 # Security Policy
 
-## Supported Versions
+Python [provides a security policy and threat model](https://devguide.python.org/security/policy/)
+in the Python Developer's Guide documenting what bugs are vulnerabilities,
+how to structure reports, and what versions of Python accept reports.
 
-The Python team applies security fixes according to the table
-in [the devguide](
-https://devguide.python.org/versions/#supported-versions
-).
+Python Security Response Team (PSRT) members
+balance security work against many other responsibilities. Please be thoughtful
+about the time and attention your report requires. Repeated failure to respect
+the security policy will result in future reports being rejected, or the
+reporter being banned from the ``python`` GitHub organization, regardless of
+technical merit.
 
 ## Reporting a Vulnerability
 
-Please read the guidelines on reporting security issues [on the
-official website](https://www.python.org/dev/security/) for
-instructions on how to report a security-related problem to
-the Python team responsibly.
+The [Python security policy](https://devguide.python.org/security/policy/)
+documents [how to submit a vulnerability report](https://devguide.python.org/security/policy/#how-to-submit-a-vulnerability-report)
+using GitHub Security Advisories. Please read the security policy
+prior to filing a vulnerability report, especially the section on [what information to
+include and exclude](https://devguide.python.org/security/policy/#what-to-include-and-how-to-structure-a-vulnerability-report)
+in vulnerability reports. Following the security policy means the PSRT can
+quickly and efficiently triage your report, not following the security policy
+will only delay triaging your report.
 
-To reach the response team, email `security at python dot org`.

-# Python for Android
-
-If you obtained this README as part of a release package, then the only
-applicable sections are "Prerequisites", "Testing", and "Using in your own app".
-
-If you obtained this README as part of the CPython source tree, then you can
-also follow the other sections to compile Python for Android yourself.
-
-However, most app developers should not need to do any of these things manually.
-Instead, use one of the tools listed
-[here](https://docs.python.org/3/using/android.html), which will provide a much
-easier experience.
-
-
-## Prerequisites
-
-If you already have an Android SDK installed, export the `ANDROID_HOME`
-environment variable to point at its location. Otherwise, here's how to install
-it:
-
-* Download the "Command line tools" from <https://developer.android.com/studio>.
-* Create a directory `android-sdk/cmdline-tools`, and unzip the command line
-  tools package into it.
-* Rename `android-sdk/cmdline-tools/cmdline-tools` to
-  `android-sdk/cmdline-tools/latest`.
-* `export ANDROID_HOME=/path/to/android-sdk`
-
-The `android.py` script will automatically use the SDK's `sdkmanager` to install
-any packages it needs.
-
-The script also requires the following commands to be on the `PATH`:
-
-* `curl`
-* `java` (or set the `JAVA_HOME` environment variable)
-
-
-## Building
-
-Python can be built for Android on any POSIX platform supported by the Android
-development tools, which currently means Linux or macOS.
-
-First we'll make a "build" Python (for your development machine), then use it to
-help produce a "host" Python for Android. So make sure you have all the usual
-tools and libraries needed to build Python for your development machine.
-
-The easiest way to do a build is to use the `android.py` script. You can either
-have it perform the entire build process from start to finish in one step, or
-you can do it in discrete steps that mirror running `configure` and `make` for
-each of the two builds of Python you end up producing.
-
-The discrete steps for building via `android.py` are:
-
-```sh
-./android.py configure-build
-./android.py make-build
-./android.py configure-host HOST
-./android.py make-host HOST
-```
-
-`HOST` identifies which architecture to build. To see the possible values, run
-`./android.py configure-host --help`.
-
-To do all steps in a single command, run:
-
-```sh
-./android.py build HOST
-```
-
-In the end you should have a build Python in `cross-build/build`, and a host
-Python in `cross-build/HOST`.
-
-You can use `--` as a separator for any of the `configure`-related commands –
-including `build` itself – to pass arguments to the underlying `configure`
-call. For example, if you want a pydebug build that also caches the results from
-`configure`, you can do:
-
-```sh
-./android.py build HOST -- -C --with-pydebug
-```
-
-
-## Packaging
-
-After building an architecture as described in the section above, you can
-package it for release with this command:
-
-```sh
-./android.py package HOST
-```
-
-`HOST` is defined in the section above.
-
-This will generate a tarball in `cross-build/HOST/dist`, whose structure is
-similar to the `Android` directory of the CPython source tree.
-
-
-## Testing
-
-The Python test suite can be run on Linux, macOS, or Windows.
-
-On Linux, the emulator needs access to the KVM virtualization interface. This may
-require adding your user to a group, or changing your udev rules. On GitHub
-Actions, the test script will do this automatically using the commands shown
-[here](https://github.blog/changelog/2024-04-02-github-actions-hardware-accelerated-android-virtualization-now-available/).
-
-The test suite can usually be run on a device with 2 GB of RAM, but this is
-borderline, so you may need to increase it to 4 GB. As of Android
-Studio Koala, 2 GB is the default for all emulators, although the user interface
-may indicate otherwise. Locate the emulator's directory under `~/.android/avd`,
-and find `hw.ramSize` in both config.ini and hardware-qemu.ini. Either set these
-manually to the same value, or use the Android Studio Device Manager, which will
-update both files.
-
-You can run the test suite either:
-
-* Within the CPython repository, after doing a build as described above. On
-  Windows, you won't be able to do the build on the same machine, so you'll have
-  to copy the `cross-build/HOST/prefix` directory from somewhere else.
-
-* Or by taking a release package built using the `package` command, extracting
-  it wherever you want, and using its own copy of `android.py`.
-
-The test script supports the following modes:
-
-* In `--connected` mode, it runs on a device or emulator you have already
-  connected to the build machine. List the available devices with
-  `$ANDROID_HOME/platform-tools/adb devices -l`, then pass a device ID to the
-  script like this:
-
-  ```sh
-  ./android.py test --connected emulator-5554
-  ```
-
-* In `--managed` mode, it uses a temporary headless emulator defined in the
-  `managedDevices` section of testbed/app/build.gradle.kts. This mode is slower,
-  but more reproducible.
-
-  We currently define two devices: `minVersion` and `maxVersion`, corresponding
-  to our minimum and maximum supported Android versions. For example:
-
-  ```sh
-  ./android.py test --managed maxVersion
-  ```
-
-By default, the only messages the script will show are Python's own stdout and
-stderr. Add the `-v` option to also show Gradle output, and non-Python logcat
-messages.
-
-Any other arguments on the `android.py test` command line will be passed through
-to `python -m test` – use `--` to separate them from android.py's own options.
-See the [Python Developer's
-Guide](https://devguide.python.org/testing/run-write-tests/) for common options
-– most of them will work on Android, except for those that involve subprocesses,
-such as `-j`.
-
-Every time you run `android.py test`, changes in pure-Python files in the
-repository's `Lib` directory will be picked up immediately. Changes in C files,
-and architecture-specific files such as sysconfigdata, will not take effect
-until you re-run `android.py make-host` or `build`.
-
-The testbed app can also be used to test third-party packages. For more details,
-run `android.py test --help`, paying attention to the options `--site-packages`,
-`--cwd`, `-c` and `-m`.
-
-
-## Using in your own app
-
-See https://docs.python.org/3/using/android.html.

-# Apple XCframework build script
-#
-# This script simplifies the process of configuring, compiling and packaging an
-# XCframework for an Apple platform.
-#
-# At present, it only supports iOS, but it has been constructed so that it
-# could be used on any Apple platform.
-#
-# The simplest entry point is:
-#
-#   $ python Apple ci iOS
-#
-# which will:
-# * Clean any pre-existing build artefacts
-# * Configure and make a Python that can be used for the build
-# * Configure and make a Python for each supported iOS architecture and ABI
-# * Combine the outputs of the builds from the previous step into a single
-#   XCframework, merging binaries into a "fat" binary if necessary
-# * Clone a copy of the testbed, configured to use the XCframework
-# * Construct a tarball containing the release artefacts
-# * Run the test suite using the generated XCframework.
-#
-# This is the complete sequence that would be needed in CI to build and test
-# a candidate release artefact.
-#
-# Each individual step can be invoked individually - there are commands to
-# clean, configure-build, make-build, configure-host, make-host, package, and
-# test.
-#
-# There is also a build command that can be used to combine the configure and
-# make steps for the build Python, an individual host, all hosts, or all
-# builds.

-# Python on iOS README
-
-**iOS support is [tier 3](https://peps.python.org/pep-0011/#tier-3).**
-
-This document provides a quick overview of some iOS specific features in the
-Python distribution.
-
-These instructions are only needed if you're planning to compile Python for iOS
-yourself. Most users should *not* need to do this. If you're looking to
-experiment with writing an iOS app in Python, tools such as [BeeWare's
-Briefcase](https://briefcase.readthedocs.io) and [Kivy's
-Buildozer](https://buildozer.readthedocs.io) will provide a much more
-approachable user experience.
-
-## Compilers for building on iOS
-
-Building for iOS requires the use of Apple's Xcode tooling. It is strongly
-recommended that you use the most recent stable release of Xcode. This will
-require the use of the most (or second-most) recently released macOS version,
-as Apple does not maintain Xcode for older macOS versions. The Xcode Command
-Line Tools are not sufficient for iOS development; you need a *full* Xcode
-install.
-
-If you want to run your code on the iOS simulator, you'll also need to install
-an iOS Simulator Platform. You should be prompted to select an iOS Simulator
-Platform when you first run Xcode. Alternatively, you can add an iOS Simulator
-Platform by selecting an open the Platforms tab of the Xcode Settings panel.
-
-## Building Python on iOS
-
-### ABIs and Architectures
-
-iOS apps can be deployed on physical devices, and on the iOS simulator. Although
-the API used on these devices is identical, the ABI is different - you need to
-link against different libraries for an iOS device build (`iphoneos`) or an
-iOS simulator build (`iphonesimulator`).
-
-Apple uses the `XCframework` format to allow specifying a single dependency
-that supports multiple ABIs. An `XCframework` is a wrapper around multiple
-ABI-specific frameworks that share a common API.
-
-iOS can also support different CPU architectures within each ABI. At present,
-there is only a single supported architecture on physical devices - ARM64.
-However, the *simulator* supports 2 architectures - ARM64 (for running on Apple
-Silicon machines), and x86_64 (for running on older Intel-based machines).
-
-To support multiple CPU architectures on a single platform, Apple uses a "fat
-binary" format - a single physical file that contains support for multiple
-architectures. It is possible to compile and use a "thin" single architecture
-version of a binary for testing purposes; however, the "thin" binary will not be
-portable to machines using other architectures.
-
-### Building a multi-architecture iOS XCframework
-
-The `Apple` subfolder of the Python repository acts as a build script that
-can be used to coordinate the compilation of a complete iOS XCframework. To use
-it, run::
-
-  python Apple build iOS
-
-This will:
-
-* Configure and compile a version of Python to run on the build machine
-* Download pre-compiled binary dependencies for each platform
-* Configure and build a `Python.framework` for each required architecture and
-  iOS SDK
-* Merge the multiple `Python.framework` folders into a single `Python.xcframework`
-* Produce a `.tar.gz` archive in the `cross-build/dist` folder containing
-  the `Python.xcframework`, plus a copy of the Testbed app pre-configured to
-  use the XCframework.
-
-The `Apple` build script has other entry points that will perform the
-individual parts of the overall `build` target, plus targets to test the
-build, clean the `cross-build` folder of iOS build products, and perform a
-complete "build and test" CI run. The `--clean` flag can also be used on
-individual commands to ensure that a stale build product are removed before
-building.
-
-### Building a single-architecture framework
-
-If you're using the `Apple` build script, you won't need to build
-individual frameworks. However, if you do need to manually configure an iOS
-Python build for a single framework, the following options are available.
-
-#### iOS specific arguments to configure
-
-* `--enable-framework[=DIR]`
-
-  This argument specifies the location where the Python.framework will be
-  installed. If `DIR` is not specified, the framework will be installed into
-  a subdirectory of the `iOS/Frameworks` folder.
-
-  This argument *must* be provided when configuring iOS builds. iOS does not
-  support non-framework builds.
-
-* `--with-framework-name=NAME`
-
-  Specify the name for the Python framework; defaults to `Python`.
-
-  > [!NOTE]
-  > Unless you know what you're doing, changing the name of the Python
-  > framework on iOS is not advised. If you use this option, you won't be able
-  > to run the `Apple` build script without making significant manual
-  > alterations, and you won't be able to use any binary packages unless you
-  > compile them yourself using your own framework name.
-
-#### Building Python for iOS
-
-The Python build system will create a `Python.framework` that supports a
-*single* ABI with a *single* architecture. Unlike macOS, iOS does not allow a
-framework to contain non-library content, so the iOS build will produce a
-`bin` and `lib` folder in the same output folder as `Python.framework`.
-The `lib` folder will be needed at runtime to support the Python library.
-
-If you want to use Python in a real iOS project, you need to produce multiple
-`Python.framework` builds, one for each ABI and architecture. iOS builds of
-Python *must* be constructed as framework builds. To support this, you must
-provide the `--enable-framework` flag when configuring the build. The build
-also requires the use of cross-compilation. The minimal commands for building
-Python for the ARM64 iOS simulator will look something like:
-```
-export PATH="$(pwd)/Apple/iOS/Resources/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin"
-./configure \
-    --enable-framework \
-    --host=arm64-apple-ios-simulator \
-    --build=arm64-apple-darwin \
-    --with-build-python=/path/to/python.exe
-make
-make install
-```
-
-In this invocation:
-
-* `Apple/iOS/Resources/bin` has been added to the path, providing some shims for the
-  compilers and linkers needed by the build. Xcode requires the use of `xcrun`
-  to invoke compiler tooling. However, if `xcrun` is pre-evaluated and the
-  result passed to `configure`, these results can embed user- and
-  version-specific paths into the sysconfig data, which limits the portability
-  of the compiled Python. Alternatively, if `xcrun` is used *as* the compiler,
-  it requires that compiler variables like `CC` include spaces, which can
-  cause significant problems with many C configuration systems which assume that
-  `CC` will be a single executable.
-
-  To work around this problem, the `Apple/iOS/Resources/bin` folder contains some
-  wrapper scripts that present as simple compilers and linkers, but wrap
-  underlying calls to `xcrun`. This allows configure to use a `CC`
-  definition without spaces, and without user- or version-specific paths, while
-  retaining the ability to adapt to the local Xcode install. These scripts are
-  included in the `bin` directory of an iOS install.
-
-  These scripts will, by default, use the currently active Xcode installation.
-  If you want to use a different Xcode installation, you can use
-  `xcode-select` to set a new default Xcode globally, or you can use the
-  `DEVELOPER_DIR` environment variable to specify an Xcode install. The
-  scripts will use the default `iphoneos`/`iphonesimulator` SDK version for
-  the select Xcode install; if you want to use a different SDK, you can set the
-  `IOS_SDK_VERSION` environment variable. (e.g, setting
-  `IOS_SDK_VERSION=17.1` would cause the scripts to use the `iphoneos17.1`
-  and `iphonesimulator17.1` SDKs, regardless of the Xcode default.)
-
-  The path has also been cleared of any user customizations. A common source of
-  bugs is for tools like Homebrew to accidentally leak macOS binaries into an iOS
-  build. Resetting the path to a known "bare bones" value is the easiest way to
-  avoid these problems.
-
-* `--host` is the architecture and ABI that you want to build, in GNU compiler
-  triple format. This will be one of:
-
-  - `arm64-apple-ios` for ARM64 iOS devices.
-  - `arm64-apple-ios-simulator` for the iOS simulator running on Apple
-    Silicon devices.
-  - `x86_64-apple-ios-simulator` for the iOS simulator running on Intel
-    devices.
-
-* `--build` is the GNU compiler triple for the machine that will be running
-  the compiler. This is one of:
-
-  - `arm64-apple-darwin` for Apple Silicon devices.
-  - `x86_64-apple-darwin` for Intel devices.
-
-* `/path/to/python.exe` is the path to a Python binary on the machine that
-  will be running the compiler. This is needed because the Python compilation
-  process involves running some Python code. On a normal desktop build of
-  Python, you can compile a python interpreter and then use that interpreter to
-  run Python code. However, the binaries produced for iOS won't run on macOS, so
-  you need to provide an external Python interpreter. This interpreter must be
-  the same version as the Python that is being compiled. To be completely safe,
-  this should be the *exact* same commit hash. However, the longer a Python
-  release has been stable, the more likely it is that this constraint can be
-  relaxed - the same micro version will often be sufficient.
-
-* The `install` target for iOS builds is slightly different to other
-  platforms. On most platforms, `make install` will install the build into
-  the final runtime location. This won't be the case for iOS, as the final
-  runtime location will be on a physical device.
-
-  However, you still need to run the `install` target for iOS builds, as it
-  performs some final framework assembly steps. The location specified with
-  `--enable-framework` will be the location where `make install` will
-  assemble the complete iOS framework. This completed framework can then
-  be copied and relocated as required.
-
-For a full CPython build, you also need to specify the paths to iOS builds of
-the binary libraries that CPython depends on (such as XZ, LibFFI and OpenSSL).
-This can be done by defining library specific environment variables (such as
-`LIBLZMA_CFLAGS`, `LIBLZMA_LIBS`), and the `--with-openssl` configure
-option. Versions of these libraries pre-compiled for iOS can be found in [this
-repository](https://github.com/beeware/cpython-apple-source-deps/releases).
-LibFFI is especially important, as many parts of the standard library
-(including the `platform`, `sysconfig` and `webbrowser` modules) require
-the use of the `ctypes` module at runtime.
-
-By default, Python will be compiled with an iOS deployment target (i.e., the
-minimum supported iOS version) of 13.0. To specify a different deployment
-target, provide the version number as part of the `--host` argument - for
-example, `--host=arm64-apple-ios15.4-simulator` would compile an ARM64
-simulator build with a deployment target of 15.4.
-
-## Testing Python on iOS
-
-### Testing a multi-architecture framework
-
-Once you have a built an XCframework, you can test that framework by running:
-
-  $ python Apple test iOS
-
-This test will attempt to find an "SE-class" simulator (i.e., an iPhone SE, or
-iPhone 16e, or similar), and run the test suite on the most recent version of
-iOS that is available. You can specify a simulator using the `--simulator`
-command line argument, providing the name of the simulator (e.g., `--simulator
-'iPhone 16 Pro'`). You can also use this argument to control the OS version used
-for testing; `--simulator 'iPhone 16 Pro,OS=18.2'` would attempt to run the
-tests on an iPhone 16 Pro running iOS 18.2.
-
-If the test runner is executed on GitHub Actions, the `GITHUB_ACTIONS`
-environment variable will be exposed to the iOS process at runtime.
-
-### Testing a single-architecture framework
-
-The `Apple/testbed` folder that contains an Xcode project that is able to run
-the Python test suite on Apple platforms. This project converts the Python test
-suite into a single test case in Xcode's XCTest framework. The single XCTest
-passes if the test suite passes.
-
-To run the test suite, configure a Python build for an iOS simulator (i.e.,
-`--host=arm64-apple-ios-simulator` or `--host=x86_64-apple-ios-simulator`
-), specifying a framework build (i.e. `--enable-framework`). Ensure that your
-`PATH` has been configured to include the `Apple/iOS/Resources/bin` folder and
-exclude any non-iOS tools, then run:
-```
-make all
-make install
-make testios
-```
-
-This will:
-
-* Build an iOS framework for your chosen architecture;
-* Finalize the single-platform framework;
-* Make a clean copy of the testbed project;
-* Install the Python iOS framework into the copy of the testbed project; and
-* Run the test suite on an "entry-level device" simulator (i.e., an iPhone SE,
-  iPhone 16e, or a similar).
-
-On success, the test suite will exit and report successful completion of the
-test suite. On a 2022 M1 MacBook Pro, the test suite takes approximately 15
-minutes to run; a couple of extra minutes is required to compile the testbed
-project, and then boot and prepare the iOS simulator.
-
-### Debugging test failures
-
-Running `python Apple test iOS` generates a standalone version of the
-`Apple/testbed` project, and runs the full test suite. It does this using
-`Apple/testbed` itself - the folder is an executable module that can be used
-to create and run a clone of the testbed project. The standalone version of the
-testbed will be created in a directory named
-`cross-build/iOS-testbed.<timestamp>`.
-
-You can generate your own standalone testbed instance by running:
-```
-python cross-build/iOS/testbed clone my-testbed
-```
-
-In this invocation, `my-testbed` is the name of the folder for the new
-testbed clone.
-
-If you've built your own XCframework, or you only want to test a single architecture,
-you can construct a standalone testbed instance by running:
-```
-python Apple/testbed clone --platform iOS --framework <path/to/framework> my-testbed
-```
-
-The framework path can be the path path to a `Python.xcframework`, or the
-path to a folder that contains a single-platform `Python.framework`.
-
-You can then use the `my-testbed` folder to run the Python test suite,
-passing in any command line arguments you may require. For example, if you're
-trying to diagnose a failure in the `os` module, you might run:
-```
-python my-testbed run -- test -W test_os
-```
-
-This is the equivalent of running `python -m test -W test_os` on a desktop
-Python build. Any arguments after the `--` will be passed to testbed as if
-they were arguments to `python -m` on a desktop machine.
-
-### Testing in Xcode
-
-You can also open the testbed project in Xcode by running:
-```
-open my-testbed/iOSTestbed.xcodeproj
-```
-
-This will allow you to use the full Xcode suite of tools for debugging.
-
-The arguments used to run the test suite are defined as part of the test plan.
-To modify the test plan, select the test plan node of the project tree (it
-should be the first child of the root node), and select the "Configurations"
-tab. Modify the "Arguments Passed On Launch" value to change the testing
-arguments.
-
-The test plan also disables parallel testing, and specifies the use of the
-`Testbed.lldbinit` file for providing configuration of the debugger. The
-default debugger configuration disables automatic breakpoints on the
-`SIGINT`, `SIGUSR1`, `SIGUSR2`, and `SIGXFSZ` signals.
-
-### Testing on an iOS device
-
-To test on an iOS device, the app needs to be signed with known developer
-credentials. To obtain these credentials, you must have an iOS Developer
-account, and your Xcode install will need to be logged into your account (see
-the Accounts tab of the Preferences dialog).
-
-Once the project is open, and you're signed into your Apple Developer account,
-select the root node of the project tree (labeled "iOSTestbed"), then the
-"Signing & Capabilities" tab in the details page. Select a development team
-(this will likely be your own name), and plug in a physical device to your
-macOS machine with a USB cable. You should then be able to select your physical
-device from the list of targets in the pulldown in the Xcode titlebar.

+.....................
+
+.. versionadded:: 3.15
+
+   Support for the :samp:`PyModExport_{<name>}` export hook was added in Python
+   3.15. The older way of defining modules is still available: consult either
+   the :ref:`extension-pyinit` section or earlier versions of this
+   documentation if you plan to support earlier Python versions.
+
+The export hook must be an exported function with the following signature:
+
+.. c:function:: PySlot *PyModExport_modulename(void)
+
+For modules with ASCII-only names, the :ref:`export hook <extension-export-hook>`
+must be named :samp:`PyModExport_{<name>}`,
+with ``<name>`` replaced by the module's name.
+
+For non-ASCII module names, the export hook must instead be named
+:samp:`PyModExportU_{<name>}` (note the ``U``), with ``<name>`` encoded using
+Python's *punycode* encoding with hyphens replaced by underscores. In Python:
+
+.. code-block:: python
+
+    def hook_name(name):
+        try:
+            suffix = b'_' + name.encode('ascii')
+        except UnicodeEncodeError:
+            suffix = b'U_' + name.encode('punycode').replace(b'-', b'_')
+        return b'PyModExport' + suffix
+
+The export hook returns an array of :c:type:`PySlot` entries,
+terminated by an entry with a slot ID of ``0``.
+These slots describe how the module should be created and initialized.
+
+This array must remain valid and constant until interpreter shutdown.
+Typically, it should use ``static`` storage.
+Prefer using the :c:macro:`Py_mod_create` and :c:macro:`Py_mod_exec` slots
+for any dynamic behavior.
+
+The export hook may return ``NULL`` with an exception set to signal failure.
+
+It is recommended to define the export hook function using a helper macro:
+
+.. c:macro:: PyMODEXPORT_FUNC
+
+   Declare an extension module export hook.
+   This macro:
+
+   * specifies the :c:expr:`PySlot*` return type,
+   * adds any special linkage declarations required by the platform, and
+   * for C++, declares the function as ``extern "C"``.
+
+For example, a module called ``spam`` would be defined like this::
 
+   PyABIInfo_VAR(abi_info);
+
+   static PySlot spam_slots[] = {
+       PySlot_STATIC_DATA(Py_mod_abi, &abi_info),
+       PySlot_STATIC_DATA(Py_mod_name, "spam"),
+       PySlot_FUNC(Py_mod_init, spam_init_function),
+       ...
+       PySlot_END
+   };
+
+   PyMODEXPORT_FUNC
+   PyModExport_spam(void)
+   {
+       return spam_slots;
+   }
+
+The export hook is typically the only non-\ ``static``
+item defined in the module's C source.
+
+.. _pymodexport-api-caveats:
+
+The hook should be kept short.
+If it does more than ``return`` a static array, several caveats apply:
+
+- If you need to use any Python C API, it is recommended to call
+  :c:func:`PyABIInfo_Check` first to raise an exception,
+  rather than crash, in common cases of ABI mismatch.
+- Code in the export hook must never rely on the :term:`GIL`:
+  :term:`free-threaded builds <free-threaded build>` of Python can only check
+  the :c:macro:`Py_mod_gil` slot (or the lack of it) after the hook returns,
+- Similarly, the hook may be called in any subinterpreter, since the
+  :c:macro:`Py_mod_multiple_interpreters` slot (or lack of it)
+  is only checked after the hook returns.
+
+For example::
+
+   PyMODEXPORT_FUNC
+   PyModExport_modulename(void)
+   {
+      if (PyABIInfo_Check(&abi_info, "modulename") < 0) {
+         /* ABI mismatch. It's not safe to examine the raised exception. */
+         return NULL;
+      }
+
+      /* use Python API (as little as possible); don't rely on GIL */
+
+      return modulename_slots;
+   }
+
+.. note::
+
+   It is possible to export multiple modules from a single shared library by
+   defining multiple export hooks.
+   However, importing  them requires a custom importer or suitably named
+   copies/links of the extension file, because Python's import machinery only
+   finds the function corresponding to the filename.

+Multi-phase initialization
+..........................
+
+The process of creating an extension module follows several phases:
+
+- Python finds and calls the export hook to get information on how to
+  create the module.
 - Before any substantial code is executed, Python can determine which
   capabilities the module supports, and it can adjust the environment or
   refuse loading an incompatible extension.
-- By default, Python itself creates the module object -- that is, it does
-  the equivalent of :py:meth:`object.__new__` for classes.
-  It also sets initial attributes like :attr:`~module.__package__` and
-  :attr:`~module.__loader__`.
-- Afterwards, the module object is initialized using extension-specific
-  code -- the equivalent of :py:meth:`~object.__init__` on classes.
+  Slots like :c:data:`Py_mod_abi`, :c:data:`Py_mod_gil` and
+  :c:data:`Py_mod_multiple_interpreters` influence this step.
+- By default, Python itself then creates the module object -- that is, it does
+  the equivalent of calling :py:meth:`~object.__new__` when creating an object.
+  This step can be overridden using the :c:data:`Py_mod_create` slot.
+- Python sets initial module attributes like :attr:`~module.__package__` and
+  :attr:`~module.__loader__`, and inserts the module object into
+  :py:attr:`sys.modules`.
+- Afterwards, the module object is initialized in an extension-specific way
+  -- the equivalent of :py:meth:`~object.__init__` when creating an object,
+  or of executing top-level code in a Python-language module.
+  The behavior is specified using the :c:data:`Py_mod_exec` slot.

+      :c:func:`!local_traverse` to have these specific names; don't name them just
+      anything.
 
+   Instances of :ref:`heap-allocated types <heap-types>` hold a reference to
+   their type. Their traversal function must therefore visit the type::
 
-.. c:type:: int (*inquiry)(PyObject *self)
+       Py_VISIT(Py_TYPE(self));
 
-   Drop references that may have created reference cycles.  Immutable objects
-   do not have to define this method since they can never directly create

-   this method (don't just call :c:func:`Py_DECREF` on a reference).  The
-   collector will call this method if it detects that this object is involved
-   in a reference cycle.
+   Alternately, the type may delegate this responsibility by
+   calling ``tp_traverse`` of a heap-allocated superclass (or another
+   heap-allocated type, if applicable).
+   If they do not, the type object may not be garbage-collected.
+
+   If the :c:macro:`Py_TPFLAGS_MANAGED_DICT` bit is set in the
+   :c:member:`~PyTypeObject.tp_flags` field, the traverse function must call

+       if (err) {
+           return err;
+       }
+
+   Only the members that the instance *owns* (by having
+   :term:`strong references <strong reference>` to them) must be
+   visited. For instance, if an object supports weak references via the
+   :c:member:`~PyTypeObject.tp_weaklist` slot, the pointer supporting
+   the linked list (what *tp_weaklist* points to) must **not** be
+   visited as the instance does not directly own the weak references to itself.
+
+   The traversal function has a limitation:
+
+   .. warning::
+
+      The traversal function must not have any side effects.  Implementations
+      may not modify the reference counts of any Python objects nor create or
+      destroy any Python objects, directly or indirectly.
+
+   This means that *most* Python C API functions may not be used, since
+   they can raise a new exception, return a new reference to a result object,
+   have internal logic that uses side effects.
+   Also, unless documented otherwise, functions that happen to not have side
+   effects may start having them in future versions, without warning.
+
+   For a list of safe functions, see a
+   :ref:`separate section <duringgc-functions>` below.
+
+   .. note::
+
+      The :c:func:`Py_VISIT` call may be skipped for those members that provably
+      cannot participate in reference cycles.
+      In the ``local_traverse`` example above, there is also a ``self->key``
+      member, but it can only be ``NULL`` or a Python string and therefore
+      cannot be part of a reference cycle.
+
+      On the other hand, even if you know a member can never be part of a cycle,
+      as a debugging aid you may want to visit it anyway just so the :mod:`gc`

-
-See :ref:`Python Initialization Configuration <init-config>` for details
-on how to configure the interpreter prior to initialization.
-
-.. _pre-init-safe:
-
-Before Python Initialization
-============================
-
-In an application embedding  Python, the :c:func:`Py_Initialize` function must
-be called before using any other Python/C API functions; with the exception of
-a few functions and the :ref:`global configuration variables
-<global-conf-vars>`.
-
-The following functions can be safely called before Python is initialized:
-
-* Functions that initialize the interpreter:
-
-  * :c:func:`Py_Initialize`
-  * :c:func:`Py_InitializeEx`
-  * :c:func:`Py_InitializeFromConfig`
-  * :c:func:`Py_BytesMain`
-  * :c:func:`Py_Main`
-  * the runtime pre-initialization functions covered in :ref:`init-config`
-
-* Configuration functions:
-
-  * :c:func:`PyImport_AppendInittab`
-  * :c:func:`PyImport_ExtendInittab`
-  * :c:func:`!PyInitFrozenExtensions`
-  * :c:func:`PyMem_SetAllocator`
-  * :c:func:`PyMem_SetupDebugHooks`
-  * :c:func:`PyObject_SetArenaAllocator`
-  * :c:func:`Py_SetProgramName`
-  * :c:func:`Py_SetPythonHome`
-  * the configuration functions covered in :ref:`init-config`
-
-* Informative functions:
-
-  * :c:func:`Py_IsInitialized`
-  * :c:func:`PyMem_GetAllocator`
-  * :c:func:`PyObject_GetArenaAllocator`
-  * :c:func:`Py_GetBuildInfo`

-
-* Utilities:
-
-  * :c:func:`Py_DecodeLocale`

-
-* Synchronization:
-
-  * :c:func:`PyMutex_Lock`
-  * :c:func:`PyMutex_Unlock`
-
-.. note::
-
-   Despite their apparent similarity to some of the functions listed above,
-   the following functions **should not be called** before the interpreter has
-   been initialized: :c:func:`Py_EncodeLocale`, :c:func:`PyEval_InitThreads`, and
-   :c:func:`Py_RunMain`.

-Global configuration variables
-==============================
-
-Python has variables for the global configuration to control different features
-and options. By default, these flags are controlled by :ref:`command line
-options <using-on-interface-options>`.
-
-When a flag is set by an option, the value of the flag is the number of times
-that the option was set. For example, ``-b`` sets :c:data:`Py_BytesWarningFlag`
-to 1 and ``-bb`` sets :c:data:`Py_BytesWarningFlag` to 2.

-   Initialize the Python interpreter.  In an application embedding  Python,
-   this should be called before using any other Python/C API functions; see
-   :ref:`Before Python Initialization <pre-init-safe>` for the few exceptions.
-
-   This initializes the table of loaded modules (``sys.modules``), and creates
-   the fundamental modules :mod:`builtins`, :mod:`__main__` and :mod:`sys`.
-   It also initializes the module search path (``sys.path``). It does not set
-   ``sys.argv``; use the :ref:`Python Initialization Configuration <init-config>`
-   API for that. This is a no-op when called for a second time (without calling
-   :c:func:`Py_FinalizeEx` first).  There is no return value; it is a fatal
-   error if the initialization fails.
-
-   Use :c:func:`Py_InitializeFromConfig` to customize the
-   :ref:`Python Initialization Configuration <init-config>`.
-
-   .. note::
-      On Windows, changes the console mode from ``O_TEXT`` to ``O_BINARY``,
-      which will also affect non-Python uses of the console using the C Runtime.

-.. c:function:: void Py_InitializeEx(int initsigs)
-
-   This function works like :c:func:`Py_Initialize` if *initsigs* is ``1``. If
-   *initsigs* is ``0``, it skips initialization registration of signal handlers,
-   which may be useful when CPython is embedded as part of a larger application.
-
-   Use :c:func:`Py_InitializeFromConfig` to customize the
-   :ref:`Python Initialization Configuration <init-config>`.
-
-
-.. c:function:: PyStatus Py_InitializeFromConfig(const PyConfig *config)
-
-   Initialize Python from *config* configuration, as described in
-   :ref:`init-from-config`.
-
-   See the :ref:`init-config` section for details on pre-initializing the
-   interpreter, populating the runtime configuration structure, and querying
-   the returned status structure.
-
-
-.. c:function:: int Py_IsInitialized()
-
-   Return true (nonzero) when the Python interpreter has been initialized, false
-   (zero) if not.  After :c:func:`Py_FinalizeEx` is called, this returns false until
-   :c:func:`Py_Initialize` is called again.
-
-
-.. c:function:: int Py_IsFinalizing()
-
-   Return true (non-zero) if the main Python interpreter is
-   :term:`shutting down <interpreter shutdown>`. Return false (zero) otherwise.
-
-   .. versionadded:: 3.13
-
-
-.. c:function:: int Py_FinalizeEx()
-
-   Undo all initializations made by :c:func:`Py_Initialize` and subsequent use of
-   Python/C API functions, and destroy all sub-interpreters (see
-   :c:func:`Py_NewInterpreter` below) that were created and not yet destroyed since
-   the last call to :c:func:`Py_Initialize`.  This is a no-op when called for a second
-   time (without calling :c:func:`Py_Initialize` again first).
-
-   Since this is the reverse of :c:func:`Py_Initialize`, it should be called
-   in the same thread with the same interpreter active.  That means
-   the main thread and the main interpreter.
-   This should never be called while :c:func:`Py_RunMain` is running.
-
-   Normally the return value is ``0``.
-   If there were errors during finalization (flushing buffered data),
-   ``-1`` is returned.
-
-   Note that Python will do a best effort at freeing all memory allocated by the Python
-   interpreter.  Therefore, any C-Extension should make sure to correctly clean up all
-   of the preveiously allocated PyObjects before using them in subsequent calls to
-   :c:func:`Py_Initialize`.  Otherwise it could introduce vulnerabilities and incorrect
-   behavior.
-
-   This function is provided for a number of reasons.  An embedding application
-   might want to restart Python without having to restart the application itself.
-   An application that has loaded the Python interpreter from a dynamically
-   loadable library (or DLL) might want to free all memory allocated by Python
-   before unloading the DLL. During a hunt for memory leaks in an application a
-   developer might want to free all memory allocated by Python before exiting from
-   the application.
-
-   **Bugs and caveats:** The destruction of modules and objects in modules is done
-   in random order; this may cause destructors (:meth:`~object.__del__` methods) to fail
-   when they depend on other objects (even functions) or modules.  Dynamically
-   loaded extension modules loaded by Python are not unloaded.  Small amounts of
-   memory allocated by the Python interpreter may not be freed (if you find a leak,
-   please report it).  Memory tied up in circular references between objects is not
-   freed.  Interned strings will all be deallocated regardless of their reference count.
-   Some memory allocated by extension modules may not be freed.  Some extensions may not
-   work properly if their initialization routine is called more than once; this can
-   happen if an application calls :c:func:`Py_Initialize` and :c:func:`Py_FinalizeEx`
-   more than once.  :c:func:`Py_FinalizeEx` must not be called recursively from
-   within itself.  Therefore, it must not be called by any code that may be run
-   as part of the interpreter shutdown process, such as :py:mod:`atexit`
-   handlers, object finalizers, or any code that may be run while flushing the
-   stdout and stderr files.

-
-   This is a backwards-compatible version of :c:func:`Py_FinalizeEx` that
-   disregards the return value.
-
-
-.. c:function:: int Py_BytesMain(int argc, char **argv)
-
-   Similar to :c:func:`Py_Main` but *argv* is an array of bytes strings,
-   allowing the calling application to delegate the text decoding step to
-   the CPython runtime.
-
-   .. versionadded:: 3.8
-
-
-.. c:function:: int Py_Main(int argc, wchar_t **argv)
-
-   The main program for the standard interpreter, encapsulating a full
-   initialization/finalization cycle, as well as additional
-   behaviour to implement reading configurations settings from the environment
-   and command line, and then executing ``__main__`` in accordance with
-   :ref:`using-on-cmdline`.
-
-   This is made available for programs which wish to support the full CPython
-   command line interface, rather than just embedding a Python runtime in a
-   larger application.
-
-   The *argc* and *argv* parameters are similar to those which are passed to a
-   C program's :c:func:`main` function, except that the *argv* entries are first
-   converted to ``wchar_t`` using :c:func:`Py_DecodeLocale`. It is also
-   important to note that the argument list entries may be modified to point to
-   strings other than those passed in (however, the contents of the strings
-   pointed to by the argument list are not modified).
-
-   The return value is ``2`` if the argument list does not represent a valid
-   Python command line, and otherwise the same as :c:func:`Py_RunMain`.
-
-   In terms of the CPython runtime configuration APIs documented in the
-   :ref:`runtime configuration <init-config>` section (and without accounting
-   for error handling), ``Py_Main`` is approximately equivalent to::
-
-      PyConfig config;
-      PyConfig_InitPythonConfig(&config);
-      PyConfig_SetArgv(&config, argc, argv);
-      Py_InitializeFromConfig(&config);
-      PyConfig_Clear(&config);
-
-      Py_RunMain();
-
-   In normal usage, an embedding application will call this function
-   *instead* of calling :c:func:`Py_Initialize`, :c:func:`Py_InitializeEx` or
-   :c:func:`Py_InitializeFromConfig` directly, and all settings will be applied
-   as described elsewhere in this documentation. If this function is instead
-   called *after* a preceding runtime initialization API call, then exactly
-   which environmental and command line configuration settings will be updated
-   is version dependent (as it depends on which settings correctly support
-   being modified after they have already been set once when the runtime was
-   first initialized).
-
-
-.. c:function:: int Py_RunMain(void)
-
-   Executes the main module in a fully configured CPython runtime.
-
-   Executes the command (:c:member:`PyConfig.run_command`), the script
-   (:c:member:`PyConfig.run_filename`) or the module
-   (:c:member:`PyConfig.run_module`) specified on the command line or in the
-   configuration. If none of these values are set, runs the interactive Python
-   prompt (REPL) using the ``__main__`` module's global namespace.
-
-   If :c:member:`PyConfig.inspect` is not set (the default), the return value
-   will be ``0`` if the interpreter exits normally (that is, without raising
-   an exception), the exit status of an unhandled :exc:`SystemExit`, or ``1``
-   for any other unhandled exception.
-
-   If :c:member:`PyConfig.inspect` is set (such as when the :option:`-i` option
-   is used), rather than returning when the interpreter exits, execution will
-   instead resume in an interactive Python prompt (REPL) using the ``__main__``
-   module's global namespace. If the interpreter exited with an exception, it
-   is immediately raised in the REPL session. The function return value is
-   then determined by the way the *REPL session* terminates: ``0``, ``1``, or
-   the status of a :exc:`SystemExit`, as specified above.
-
-   This function always finalizes the Python interpreter before it returns.
-
-   See :ref:`Python Configuration <init-python-config>` for an example of a
-   customized Python that always runs in isolated mode using
-   :c:func:`Py_RunMain`.
-
-.. c:function:: int PyUnstable_AtExit(PyInterpreterState *interp, void (*func)(void *), void *data)
-
-   Register an :mod:`atexit` callback for the target interpreter *interp*.
-   This is similar to :c:func:`Py_AtExit`, but takes an explicit interpreter and
-   data pointer for the callback.
-
-   There must be an :term:`attached thread state` for *interp*.

-
-   This API is kept for backward compatibility: setting

-   Initialization Configuration <init-config>`.
-
-   This function should be called before :c:func:`Py_Initialize` is called for
-   the first time, if it is called at all.  It tells the interpreter the value
-   of the ``argv[0]`` argument to the :c:func:`main` function of the program
-   (converted to wide characters).
-   This is used by some other functions below to find
-   the Python run-time libraries relative to the interpreter executable.  The
-   default value is ``'python'``.  The argument should point to a
-   zero-terminated wide character string in static storage whose contents will not
-   change for the duration of the program's execution.  No code in the Python
-   interpreter will change the contents of this storage.
-
-   Use :c:func:`Py_DecodeLocale` to decode a bytes string to get a
-   :c:expr:`wchar_t*` string.
-
-   .. deprecated-removed:: 3.11 3.15
-
-
-.. c:function:: const char* Py_GetVersion()
-
-   Return the version of this Python interpreter.  This is a string that looks
-   something like ::
-
-      "3.0a5+ (py3k:63103M, May 12 2008, 00:53:55) \n[GCC 4.2.3]"
-
-   .. index:: single: version (in module sys)
-
-   The first word (up to the first space character) is the current Python version;
-   the first characters are the major and minor version separated by a
-   period.  The returned string points into static storage; the caller should not
-   modify its value.  The value is available to Python code as :data:`sys.version`.
-
-   See also the :c:var:`Py_Version` constant.
-
-
-.. c:function:: const char* Py_GetPlatform()
-
-   .. index:: single: platform (in module sys)
-
-   Return the platform identifier for the current platform.  On Unix, this is
-   formed from the "official" name of the operating system, converted to lower
-   case, followed by the major revision number; e.g., for Solaris 2.x, which is
-   also known as SunOS 5.x, the value is ``'sunos5'``.  On macOS, it is
-   ``'darwin'``.  On Windows, it is ``'win'``.  The returned string points into
-   static storage; the caller should not modify its value.  The value is available
-   to Python code as ``sys.platform``.
-
-
-.. c:function:: const char* Py_GetCopyright()
-
-   Return the official copyright string for the current Python version, for example
-
-   ``'Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam'``
-
-   .. index:: single: copyright (in module sys)
-
-   The returned string points into static storage; the caller should not modify its
-   value.  The value is available to Python code as ``sys.copyright``.
-
-
-.. c:function:: const char* Py_GetCompiler()
-
-   Return an indication of the compiler used to build the current Python version,
-   in square brackets, for example::
-
-      "[GCC 2.7.2.2]"
-
-   .. index:: single: version (in module sys)
-
-   The returned string points into static storage; the caller should not modify its
-   value.  The value is available to Python code as part of the variable
-   ``sys.version``.
-
-
-.. c:function:: const char* Py_GetBuildInfo()
-
-   Return information about the sequence number and build date and time  of the
-   current Python interpreter instance, for example ::
-
-      "#67, Aug  1 1997, 22:34:28"
-
-   .. index:: single: version (in module sys)

-
-   .. index::
-      single: main()
-      single: Py_FatalError()
-      single: argv (in module sys)
-
-   This API is kept for backward compatibility: setting
-   :c:member:`PyConfig.argv`, :c:member:`PyConfig.parse_argv` and
-   :c:member:`PyConfig.safe_path` should be used instead, see :ref:`Python
-   Initialization Configuration <init-config>`.
-
-   Set :data:`sys.argv` based on *argc* and *argv*.  These parameters are
-   similar to those passed to the program's :c:func:`main` function with the
-   difference that the first entry should refer to the script file to be
-   executed rather than the executable hosting the Python interpreter.  If there
-   isn't a script that will be run, the first entry in *argv* can be an empty
-   string.  If this function fails to initialize :data:`sys.argv`, a fatal
-   condition is signalled using :c:func:`Py_FatalError`.
-
-   If *updatepath* is zero, this is all the function does.  If *updatepath*
-   is non-zero, the function also modifies :data:`sys.path` according to the
-   following algorithm:
-
-   - If the name of an existing script is passed in ``argv[0]``, the absolute
-     path of the directory where the script is located is prepended to
-     :data:`sys.path`.
-   - Otherwise (that is, if *argc* is ``0`` or ``argv[0]`` doesn't point
-     to an existing file name), an empty string is prepended to
-     :data:`sys.path`, which is the same as prepending the current working
-     directory (``"."``).
-
-   Use :c:func:`Py_DecodeLocale` to decode a bytes string to get a
-   :c:expr:`wchar_t*` string.
-
-   See also :c:member:`PyConfig.orig_argv` and :c:member:`PyConfig.argv`
-   members of the :ref:`Python Initialization Configuration <init-config>`.
-
-   .. note::
-      It is recommended that applications embedding the Python interpreter
-      for purposes other than executing a single script pass ``0`` as *updatepath*,
-      and update :data:`sys.path` themselves if desired.
-      See :cve:`2008-5983`.
-
-      On versions before 3.1.3, you can achieve the same effect by manually
-      popping the first :data:`sys.path` element after having called
-      :c:func:`PySys_SetArgv`, for example using::
-
-         PyRun_SimpleString("import sys; sys.path.pop(0)\n");

-
-   Set the default "home" directory, that is, the location of the standard
-   Python libraries.  See :envvar:`PYTHONHOME` for the meaning of the
-   argument string.
-
-   The argument should point to a zero-terminated character string in static
-   storage whose contents will not change for the duration of the program's
-   execution.  No code in the Python interpreter will change the contents of

-
-Thread State and the Global Interpreter Lock
-============================================
-
-.. index::
-   single: global interpreter lock
-   single: interpreter lock
-   single: lock, interpreter
-
-Unless on a :term:`free-threaded <free threading>` build of :term:`CPython`,
-the Python interpreter is not fully thread-safe.  In order to support
-multi-threaded Python programs, there's a global lock, called the :term:`global
-interpreter lock` or :term:`GIL`, that must be held by the current thread before
-it can safely access Python objects. Without the lock, even the simplest
-operations could cause problems in a multi-threaded program: for example, when
-two threads simultaneously increment the reference count of the same object, the
-reference count could end up being incremented only once instead of twice.
-
-.. index:: single: setswitchinterval (in module sys)
-
-Therefore, the rule exists that only the thread that has acquired the
-:term:`GIL` may operate on Python objects or call Python/C API functions.
-In order to emulate concurrency of execution, the interpreter regularly
-tries to switch threads (see :func:`sys.setswitchinterval`).  The lock is also
-released around potentially blocking I/O operations like reading or writing
-a file, so that other Python threads can run in the meantime.
-
-.. index::
-   single: PyThreadState (C type)
-
-The Python interpreter keeps some thread-specific bookkeeping information
-inside a data structure called :c:type:`PyThreadState`, known as a :term:`thread state`.
-Each OS thread has a thread-local pointer to a :c:type:`PyThreadState`; a thread state
-referenced by this pointer is considered to be :term:`attached <attached thread state>`.
-
-A thread can only have one :term:`attached thread state` at a time. An attached
-thread state is typically analogous with holding the :term:`GIL`, except on
-:term:`free-threaded <free threading>` builds.  On builds with the :term:`GIL` enabled,
-:term:`attaching <attached thread state>` a thread state will block until the :term:`GIL`
-can be acquired. However,  even on builds with the :term:`GIL` disabled, it is still required
-to have an attached thread state to call most of the C API.
-
-In general, there will always be an :term:`attached thread state` when using Python's C API.
-Only in some specific cases (such as in a :c:macro:`Py_BEGIN_ALLOW_THREADS` block) will the
-thread not have an attached thread state. If uncertain, check if :c:func:`PyThreadState_GetUnchecked` returns
-``NULL``.
-
-Detaching the thread state from extension code
-----------------------------------------------
-
-Most extension code manipulating the :term:`thread state` has the following simple
-structure::
-
-   Save the thread state in a local variable.
-   ... Do some blocking I/O operation ...
-   Restore the thread state from the local variable.
-
-This is so common that a pair of macros exists to simplify it::
-
-   Py_BEGIN_ALLOW_THREADS
-   ... Do some blocking I/O operation ...
-   Py_END_ALLOW_THREADS
-
-.. index::
-   single: Py_BEGIN_ALLOW_THREADS (C macro)
-   single: Py_END_ALLOW_THREADS (C macro)
-
-The :c:macro:`Py_BEGIN_ALLOW_THREADS` macro opens a new block and declares a
-hidden local variable; the :c:macro:`Py_END_ALLOW_THREADS` macro closes the
-block.
-
-The block above expands to the following code::
-
-   PyThreadState *_save;
-
-   _save = PyEval_SaveThread();
-   ... Do some blocking I/O operation ...
-   PyEval_RestoreThread(_save);
-
-.. index::
-   single: PyEval_RestoreThread (C function)
-   single: PyEval_SaveThread (C function)
-
-Here is how these functions work:
-
-The :term:`attached thread state` holds the :term:`GIL` for the entire interpreter. When detaching
-the :term:`attached thread state`, the :term:`GIL` is released, allowing other threads to attach
-a thread state to their own thread, thus getting the :term:`GIL` and can start executing.
-The pointer to the prior :term:`attached thread state` is stored as a local variable.
-Upon reaching :c:macro:`Py_END_ALLOW_THREADS`, the thread state that was
-previously :term:`attached <attached thread state>` is passed to :c:func:`PyEval_RestoreThread`.
-This function will block until another releases its :term:`thread state <attached thread state>`,
-thus allowing the old :term:`thread state <attached thread state>` to get re-attached and the
-C API can be called again.
-
-For :term:`free-threaded <free threading>` builds, the :term:`GIL` is normally
-out of the question, but detaching the :term:`thread state <attached thread state>` is still required
-for blocking I/O and long operations. The difference is that threads don't have to wait for the :term:`GIL`
-to be released to attach their thread state, allowing true multi-core parallelism.
-
-.. note::
-   Calling system I/O functions is the most common use case for detaching
-   the :term:`thread state <attached thread state>`, but it can also be useful before calling
-   long-running computations which don't need access to Python objects, such
-   as compression or cryptographic functions operating over memory buffers.
-   For example, the standard :mod:`zlib` and :mod:`hashlib` modules detach the
-   :term:`thread state <attached thread state>` when compressing or hashing data.
-
-
-.. _gilstate:
-
-Non-Python created threads
---------------------------
-
-When threads are created using the dedicated Python APIs (such as the
-:mod:`threading` module), a thread state is automatically associated to them
-and the code showed above is therefore correct.  However, when threads are
-created from C (for example by a third-party library with its own thread
-management), they don't hold the :term:`GIL`, because they don't have an
-:term:`attached thread state`.
-
-If you need to call Python code from these threads (often this will be part
-of a callback API provided by the aforementioned third-party library),
-you must first register these threads with the interpreter by
-creating an :term:`attached thread state` before you can start using the Python/C
-API.  When you are done, you should detach the :term:`thread state <attached thread state>`, and
-finally free it.
-
-The :c:func:`PyGILState_Ensure` and :c:func:`PyGILState_Release` functions do
-all of the above automatically.  The typical idiom for calling into Python
-from a C thread is::
-
-   PyGILState_STATE gstate;
-   gstate = PyGILState_Ensure();
-
-   /* Perform Python actions here. */
-   result = CallSomeFunction();
-   /* evaluate result or handle exception */
-
-   /* Release the thread. No Python API allowed beyond this point. */
-   PyGILState_Release(gstate);
-
-Note that the ``PyGILState_*`` functions assume there is only one global
-interpreter (created automatically by :c:func:`Py_Initialize`).  Python
-supports the creation of additional interpreters (using
-:c:func:`Py_NewInterpreter`), but mixing multiple interpreters and the
-``PyGILState_*`` API is unsupported. This is because :c:func:`PyGILState_Ensure`
-and similar functions default to :term:`attaching <attached thread state>` a
-:term:`thread state` for the main interpreter, meaning that the thread can't safely
-interact with the calling subinterpreter.
-
-Supporting subinterpreters in non-Python threads
-------------------------------------------------
-
-If you would like to support subinterpreters with non-Python created threads, you
-must use the ``PyThreadState_*`` API instead of the traditional ``PyGILState_*``
-API.
-
-In particular, you must store the interpreter state from the calling
-function and pass it to :c:func:`PyThreadState_New`, which will ensure that
-the :term:`thread state` is targeting the correct interpreter::
-
-   /* The return value of PyInterpreterState_Get() from the
-      function that created this thread. */
-   PyInterpreterState *interp = ThreadData->interp;
-   PyThreadState *tstate = PyThreadState_New(interp);
-   PyThreadState_Swap(tstate);
-
-   /* GIL of the subinterpreter is now held.
-      Perform Python actions here. */
-   result = CallSomeFunction();
-   /* evaluate result or handle exception */
-
-   /* Destroy the thread state. No Python API allowed beyond this point. */
-   PyThreadState_Clear(tstate);
-   PyThreadState_DeleteCurrent();
-
-.. _fork-and-threads:
-
-Cautions about fork()
----------------------
-
-Another important thing to note about threads is their behaviour in the face
-of the C :c:func:`fork` call. On most systems with :c:func:`fork`, after a
-process forks only the thread that issued the fork will exist.  This has a
-concrete impact both on how locks must be handled and on all stored state
-in CPython's runtime.
-
-The fact that only the "current" thread remains
-means any locks held by other threads will never be released. Python solves
-this for :func:`os.fork` by acquiring the locks it uses internally before
-the fork, and releasing them afterwards. In addition, it resets any
-:ref:`lock-objects` in the child. When extending or embedding Python, there
-is no way to inform Python of additional (non-Python) locks that need to be
-acquired before or reset after a fork. OS facilities such as
-:c:func:`!pthread_atfork` would need to be used to accomplish the same thing.
-Additionally, when extending or embedding Python, calling :c:func:`fork`
-directly rather than through :func:`os.fork` (and returning to or calling
-into Python) may result in a deadlock by one of Python's internal locks
-being held by a thread that is defunct after the fork.
-:c:func:`PyOS_AfterFork_Child` tries to reset the necessary locks, but is not
-always able to.
-
-The fact that all other threads go away also means that CPython's
-runtime state there must be cleaned up properly, which :func:`os.fork`
-does.  This means finalizing all other :c:type:`PyThreadState` objects
-belonging to the current interpreter and all other
-:c:type:`PyInterpreterState` objects.  Due to this and the special
-nature of the :ref:`"main" interpreter <sub-interpreter-support>`,
-:c:func:`fork` should only be called in that interpreter's "main"
-thread, where the CPython global runtime was originally initialized.
-The only exception is if :c:func:`exec` will be called immediately
-after.

-
-Cautions regarding runtime finalization
----------------------------------------
-
-In the late stage of :term:`interpreter shutdown`, after attempting to wait for
-non-daemon threads to exit (though this can be interrupted by
-:class:`KeyboardInterrupt`) and running the :mod:`atexit` functions, the runtime
-is marked as *finalizing*: :c:func:`Py_IsFinalizing` and
-:func:`sys.is_finalizing` return true.  At this point, only the *finalization
-thread* that initiated finalization (typically the main thread) is allowed to
-acquire the :term:`GIL`.
-
-If any thread, other than the finalization thread, attempts to attach a :term:`thread state`
-during finalization, either explicitly or
-implicitly, the thread enters **a permanently blocked state**
-where it remains until the program exits.  In most cases this is harmless, but this can result
-in deadlock if a later stage of finalization attempts to acquire a lock owned by the
-blocked thread, or otherwise waits on the blocked thread.
-
-Gross? Yes. This prevents random crashes and/or unexpectedly skipped C++
-finalizations further up the call stack when such threads were forcibly exited
-here in CPython 3.13 and earlier. The CPython runtime :term:`thread state` C APIs
-have never had any error reporting or handling expectations at :term:`thread state`
-attachment time that would've allowed for graceful exit from this situation. Changing that
-would require new stable C APIs and rewriting the majority of C code in the
-CPython ecosystem to use those with error handling.
-
-
-High-level API
---------------
-
-These are the most commonly used types and functions when writing C extension
-code, or when embedding the Python interpreter:
-
-.. c:type:: PyInterpreterState
-
-   This data structure represents the state shared by a number of cooperating
-   threads.  Threads belonging to the same interpreter share their module
-   administration and a few other internal items. There are no public members in
-   this structure.
-
-   Threads belonging to different interpreters initially share nothing, except
-   process state like available memory, open file descriptors and such.  The global
-   interpreter lock is also shared by all threads, regardless of to which
-   interpreter they belong.
-
-   .. versionchanged:: 3.12
-
-      :pep:`684` introduced the possibility
-      of a :ref:`per-interpreter GIL <per-interpreter-gil>`.
-      See :c:func:`Py_NewInterpreterFromConfig`.
-
-
-.. c:type:: PyThreadState
-
-   This data structure represents the state of a single thread.  The only public
-   data member is:
-
-   .. c:member:: PyInterpreterState *interp
-
-      This thread's interpreter state.
-
-
-.. c:function:: void PyEval_InitThreads()
-
-   .. index::
-      single: PyEval_AcquireThread()
-      single: PyEval_ReleaseThread()
-      single: PyEval_SaveThread()
-      single: PyEval_RestoreThread()
-
-   Deprecated function which does nothing.
-
-   In Python 3.6 and older, this function created the GIL if it didn't exist.
-
-   .. versionchanged:: 3.9
-      The function now does nothing.
-
-   .. versionchanged:: 3.7
-      This function is now called by :c:func:`Py_Initialize()`, so you don't
-      have to call it yourself anymore.
-
-   .. versionchanged:: 3.2
-      This function cannot be called before :c:func:`Py_Initialize()` anymore.
-
-   .. deprecated:: 3.9
-
-   .. index:: pair: module; _thread
-
-
-.. c:function:: PyThreadState* PyEval_SaveThread()
-
-   Detach the :term:`attached thread state` and return it.
-   The thread will have no :term:`thread state` upon returning.
-
-
-.. c:function:: void PyEval_RestoreThread(PyThreadState *tstate)
-
-   Set the :term:`attached thread state` to *tstate*.
-   The passed :term:`thread state` **should not** be :term:`attached <attached thread state>`,
-   otherwise deadlock ensues. *tstate* will be attached upon returning.
-
-   .. note::
-      Calling this function from a thread when the runtime is finalizing will
-      hang the thread until the program exits, even if the thread was not
-      created by Python.  Refer to
-      :ref:`cautions-regarding-runtime-finalization` for more details.
-
-   .. versionchanged:: 3.14
-      Hangs the current thread, rather than terminating it, if called while the
-      interpreter is finalizing.
-
-.. c:function:: PyThreadState* PyThreadState_Get()
-
-   Return the :term:`attached thread state`. If the thread has no attached
-   thread state, (such as when inside of :c:macro:`Py_BEGIN_ALLOW_THREADS`
-   block), then this issues a fatal error (so that the caller needn't check
-   for ``NULL``).
-
-   See also :c:func:`PyThreadState_GetUnchecked`.
-
-.. c:function:: PyThreadState* PyThreadState_GetUnchecked()
-
-   Similar to :c:func:`PyThreadState_Get`, but don't kill the process with a
-   fatal error if it is NULL. The caller is responsible to check if the result
-   is NULL.
-
-   .. versionadded:: 3.13
-      In Python 3.5 to 3.12, the function was private and known as
-      ``_PyThreadState_UncheckedGet()``.
-
-
-.. c:function:: PyThreadState* PyThreadState_Swap(PyThreadState *tstate)
-
-   Set the :term:`attached thread state` to *tstate*, and return the
-   :term:`thread state` that was attached prior to calling.
-
-   This function is safe to call without an :term:`attached thread state`; it
-   will simply return ``NULL`` indicating that there was no prior thread state.
-
-   .. seealso::
-      :c:func:`PyEval_ReleaseThread`
-
-   .. note::
-      Similar to :c:func:`PyGILState_Ensure`, this function will hang the
-      thread if the runtime is finalizing.
-
-
-The following functions use thread-local storage, and are not compatible
-with sub-interpreters:
-
-.. c:type:: PyGILState_STATE
-
-   The type of the value returned by :c:func:`PyGILState_Ensure` and passed to
-   :c:func:`PyGILState_Release`.
-
-   .. c:enumerator:: PyGILState_LOCKED
-
-      The GIL was already held when :c:func:`PyGILState_Ensure` was called.
-
-   .. c:enumerator:: PyGILState_UNLOCKED
-
-      The GIL was not held when :c:func:`PyGILState_Ensure` was called.
-
-.. c:function:: PyGILState_STATE PyGILState_Ensure()
-
-   Ensure that the current thread is ready to call the Python C API regardless
-   of the current state of Python, or of the :term:`attached thread state`. This may
-   be called as many times as desired by a thread as long as each call is
-   matched with a call to :c:func:`PyGILState_Release`. In general, other
-   thread-related APIs may be used between :c:func:`PyGILState_Ensure` and
-   :c:func:`PyGILState_Release` calls as long as the thread state is restored to
-   its previous state before the Release().  For example, normal usage of the
-   :c:macro:`Py_BEGIN_ALLOW_THREADS` and :c:macro:`Py_END_ALLOW_THREADS` macros is
-   acceptable.
-
-   The return value is an opaque "handle" to the :term:`attached thread state` when
-   :c:func:`PyGILState_Ensure` was called, and must be passed to
-   :c:func:`PyGILState_Release` to ensure Python is left in the same state. Even
-   though recursive calls are allowed, these handles *cannot* be shared - each
-   unique call to :c:func:`PyGILState_Ensure` must save the handle for its call
-   to :c:func:`PyGILState_Release`.
-
-   When the function returns, there will be an :term:`attached thread state`
-   and the thread will be able to call arbitrary Python code.  Failure is a fatal error.
-
-   .. warning::
-      Calling this function when the runtime is finalizing is unsafe. Doing
-      so will either hang the thread until the program ends, or fully crash
-      the interpreter in rare cases. Refer to
-      :ref:`cautions-regarding-runtime-finalization` for more details.
-
-   .. versionchanged:: 3.14
-      Hangs the current thread, rather than terminating it, if called while the
-      interpreter is finalizing.
-
-.. c:function:: void PyGILState_Release(PyGILState_STATE)
-
-   Release any resources previously acquired.  After this call, Python's state will
-   be the same as it was prior to the corresponding :c:func:`PyGILState_Ensure` call
-   (but generally this state will be unknown to the caller, hence the use of the
-   GILState API).
-
-   Every call to :c:func:`PyGILState_Ensure` must be matched by a call to
-   :c:func:`PyGILState_Release` on the same thread.
-
-.. c:function:: PyThreadState* PyGILState_GetThisThreadState()
-
-   Get the :term:`attached thread state` for this thread.  May return ``NULL`` if no
-   GILState API has been used on the current thread.  Note that the main thread
-   always has such a thread-state, even if no auto-thread-state call has been
-   made on the main thread.  This is mainly a helper/diagnostic function.
-
-   .. note::
-      This function may return non-``NULL`` even when the :term:`thread state`
-      is detached.
-      Prefer :c:func:`PyThreadState_Get` or :c:func:`PyThreadState_GetUnchecked`
-      for most cases.
-
-   .. seealso:: :c:func:`PyThreadState_Get`
-
-.. c:function:: int PyGILState_Check()
-
-   Return ``1`` if the current thread is holding the :term:`GIL` and ``0`` otherwise.
-   This function can be called from any thread at any time.
-   Only if it has had its :term:`thread state <attached thread state>` initialized
-   via :c:func:`PyGILState_Ensure` will it return ``1``.
-   This is mainly a helper/diagnostic function.  It can be useful
-   for example in callback contexts or memory allocation functions when
-   knowing that the :term:`GIL` is locked can allow the caller to perform sensitive
-   actions or otherwise behave differently.
-
-   .. note::
-      If the current Python process has ever created a subinterpreter, this
-      function will *always* return ``1``. Prefer :c:func:`PyThreadState_GetUnchecked`
-      for most cases.
-
-   .. versionadded:: 3.4
-
-
-The following macros are normally used without a trailing semicolon; look for
-example usage in the Python source distribution.
-
-
-.. c:macro:: Py_BEGIN_ALLOW_THREADS
-
-   This macro expands to ``{ PyThreadState *_save; _save = PyEval_SaveThread();``.
-   Note that it contains an opening brace; it must be matched with a following
-   :c:macro:`Py_END_ALLOW_THREADS` macro.  See above for further discussion of this
-   macro.
-
-
-.. c:macro:: Py_END_ALLOW_THREADS
-
-   This macro expands to ``PyEval_RestoreThread(_save); }``. Note that it contains
-   a closing brace; it must be matched with an earlier
-   :c:macro:`Py_BEGIN_ALLOW_THREADS` macro.  See above for further discussion of
-   this macro.
-
-
-.. c:macro:: Py_BLOCK_THREADS
-
-   This macro expands to ``PyEval_RestoreThread(_save);``: it is equivalent to
-   :c:macro:`Py_END_ALLOW_THREADS` without the closing brace.
-
-
-.. c:macro:: Py_UNBLOCK_THREADS
-
-   This macro expands to ``_save = PyEval_SaveThread();``: it is equivalent to
-   :c:macro:`Py_BEGIN_ALLOW_THREADS` without the opening brace and variable
-   declaration.

-Low-level API
--------------
-
-All of the following functions must be called after :c:func:`Py_Initialize`.
-
-.. versionchanged:: 3.7
-   :c:func:`Py_Initialize()` now initializes the :term:`GIL`
-   and sets an :term:`attached thread state`.
-
-
-.. c:function:: PyInterpreterState* PyInterpreterState_New()
-
-   Create a new interpreter state object.  An :term:`attached thread state` is not needed,
-   but may optionally exist if it is necessary to serialize calls to this
-   function.
-
-   .. audit-event:: cpython.PyInterpreterState_New "" c.PyInterpreterState_New
-
-
-.. c:function:: void PyInterpreterState_Clear(PyInterpreterState *interp)

-
-
-.. c:function:: void PyInterpreterState_Delete(PyInterpreterState *interp)
-
-   Destroy an interpreter state object.  There **should not** be an
-   :term:`attached thread state` for the target interpreter. The interpreter

-
-
-.. c:function:: PyThreadState* PyThreadState_New(PyInterpreterState *interp)
-
-   Create a new thread state object belonging to the given interpreter object.
-   An :term:`attached thread state` is not needed.
-
-.. c:function:: void PyThreadState_Clear(PyThreadState *tstate)
-
-   Reset all information in a :term:`thread state` object.  *tstate*
-   must be :term:`attached <attached thread state>`
-
-   .. versionchanged:: 3.9
-      This function now calls the :c:member:`!PyThreadState.on_delete` callback.
-      Previously, that happened in :c:func:`PyThreadState_Delete`.
-
-   .. versionchanged:: 3.13
-      The :c:member:`!PyThreadState.on_delete` callback was removed.
-
-
-.. c:function:: void PyThreadState_Delete(PyThreadState *tstate)
-
-   Destroy a :term:`thread state` object.  *tstate* should not
-   be :term:`attached <attached thread state>` to any thread.
-   *tstate* must have been reset with a previous call to
-   :c:func:`PyThreadState_Clear`.
-
-
-.. c:function:: void PyThreadState_DeleteCurrent(void)
-
-   Detach the :term:`attached thread state` (which must have been reset
-   with a previous call to :c:func:`PyThreadState_Clear`) and then destroy it.
-
-   No :term:`thread state` will be :term:`attached <attached thread state>` upon
-   returning.
-
-.. c:function:: PyFrameObject* PyThreadState_GetFrame(PyThreadState *tstate)
-
-   Get the current frame of the Python thread state *tstate*.
-
-   Return a :term:`strong reference`. Return ``NULL`` if no frame is currently
-   executing.
-
-   See also :c:func:`PyEval_GetFrame`.

-
-   .. versionadded:: 3.9
-
-
-.. c:function:: PyInterpreterState* PyThreadState_GetInterpreter(PyThreadState *tstate)

-
-   .. versionadded:: 3.9
-
-
-.. c:function:: void PyThreadState_EnterTracing(PyThreadState *tstate)
-
-   Suspend tracing and profiling in the Python thread state *tstate*.
-
-   Resume them using the :c:func:`PyThreadState_LeaveTracing` function.
-
-   .. versionadded:: 3.11
-
-
-.. c:function:: void PyThreadState_LeaveTracing(PyThreadState *tstate)
-

-
-
-.. c:function:: int PyUnstable_ThreadState_SetStackProtection(PyThreadState *tstate, void *stack_start_addr, size_t stack_size)
-
-   Set the stack protection start address and stack protection size
-   of a Python thread state.
-
-   On success, return ``0``.
-   On failure, set an exception and return ``-1``.
-
-   CPython implements :ref:`recursion control <recursion>` for C code by raising
-   :py:exc:`RecursionError` when it notices that the machine execution stack is close
-   to overflow. See for example the :c:func:`Py_EnterRecursiveCall` function.
-   For this, it needs to know the location of the current thread's stack, which it
-   normally gets from the operating system.
-   When the stack is changed, for example using context switching techniques like the
-   Boost library's ``boost::context``, you must call
-   :c:func:`~PyUnstable_ThreadState_SetStackProtection` to inform CPython of the change.
-
-   Call :c:func:`~PyUnstable_ThreadState_SetStackProtection` either before
-   or after changing the stack.
-   Do not call any other Python C API between the call and the stack
-   change.
-
-   See :c:func:`PyUnstable_ThreadState_ResetStackProtection` for undoing this operation.
-
-   .. versionadded:: next
-
-
-.. c:function:: void PyUnstable_ThreadState_ResetStackProtection(PyThreadState *tstate)
-
-   Reset the stack protection start address and stack protection size

-
-   See :c:func:`PyUnstable_ThreadState_SetStackProtection` for an explanation.
-
-   .. versionadded:: next
-
-
-.. c:function:: PyInterpreterState* PyInterpreterState_Get(void)
-
-   Get the current interpreter.
-
-   Issue a fatal error if there no :term:`attached thread state`.
-   It cannot return NULL.
-
-   .. versionadded:: 3.9
-
-
-.. c:function:: int64_t PyInterpreterState_GetID(PyInterpreterState *interp)
-
-   Return the interpreter's unique ID.  If there was any error in doing
-   so then ``-1`` is returned and an error is set.
-
-   The caller must have an :term:`attached thread state`.
-
-   .. versionadded:: 3.7
-
-
-.. c:function:: PyObject* PyInterpreterState_GetDict(PyInterpreterState *interp)
-
-   Return a dictionary in which interpreter-specific data may be stored.
-   If this function returns ``NULL`` then no exception has been raised and
-   the caller should assume no interpreter-specific dict is available.
-
-   This is not a replacement for :c:func:`PyModule_GetState()`, which
-   extensions should use to store interpreter-specific state information.
-
-   The returned dictionary is borrowed from the interpreter and is valid until
-   interpreter shutdown.
-
-   .. versionadded:: 3.8
-
-
-.. c:type:: PyObject* (*_PyFrameEvalFunction)(PyThreadState *tstate, _PyInterpreterFrame *frame, int throwflag)
-
-   Type of a frame evaluation function.
-
-   The *throwflag* parameter is used by the ``throw()`` method of generators:
-   if non-zero, handle the current exception.
-
-   .. versionchanged:: 3.9
-      The function now takes a *tstate* parameter.
-
-   .. versionchanged:: 3.11
-      The *frame* parameter changed from ``PyFrameObject*`` to ``_PyInterpreterFrame*``.
-
-.. c:function:: _PyFrameEvalFunction _PyInterpreterState_GetEvalFrameFunc(PyInterpreterState *interp)
-
-   Get the frame evaluation function.
-
-   See the :pep:`523` "Adding a frame evaluation API to CPython".
-
-   .. versionadded:: 3.9
-
-.. c:function:: void _PyInterpreterState_SetEvalFrameFunc(PyInterpreterState *interp, _PyFrameEvalFunction eval_frame)
-
-   Set the frame evaluation function.
-
-   See the :pep:`523` "Adding a frame evaluation API to CPython".
-
-   .. versionadded:: 3.9
-
-
-.. c:function:: PyObject* PyThreadState_GetDict()
-
-   Return a dictionary in which extensions can store thread-specific state
-   information.  Each extension should use a unique key to use to store state in
-   the dictionary.  It is okay to call this function when no :term:`thread state`
-   is :term:`attached <attached thread state>`. If this function returns
-   ``NULL``, no exception has been raised and the caller should assume no
-   thread state is attached.
-
-
-.. c:function:: int PyThreadState_SetAsyncExc(unsigned long id, PyObject *exc)
-
-   Asynchronously raise an exception in a thread. The *id* argument is the thread
-   id of the target thread; *exc* is the exception object to be raised. This
-   function does not steal any references to *exc*. To prevent naive misuse, you
-   must write your own C extension to call this.  Must be called with an :term:`attached thread state`.
-   Returns the number of thread states modified; this is normally one, but will be
-   zero if the thread id isn't found.  If *exc* is ``NULL``, the pending
-   exception (if any) for the thread is cleared. This raises no exceptions.
-
-   .. versionchanged:: 3.7
-      The type of the *id* parameter changed from :c:expr:`long` to
-      :c:expr:`unsigned long`.
-
-.. c:function:: void PyEval_AcquireThread(PyThreadState *tstate)
-
-   :term:`Attach <attached thread state>` *tstate* to the current thread,
-   which must not be ``NULL`` or already :term:`attached <attached thread state>`.
-
-   The calling thread must not already have an :term:`attached thread state`.
-
-   .. note::
-      Calling this function from a thread when the runtime is finalizing will
-      hang the thread until the program exits, even if the thread was not
-      created by Python.  Refer to
-      :ref:`cautions-regarding-runtime-finalization` for more details.
-
-   .. versionchanged:: 3.8
-      Updated to be consistent with :c:func:`PyEval_RestoreThread`,
-      :c:func:`Py_END_ALLOW_THREADS`, and :c:func:`PyGILState_Ensure`,
-      and terminate the current thread if called while the interpreter is finalizing.
-
-   .. versionchanged:: 3.14
-      Hangs the current thread, rather than terminating it, if called while the
-      interpreter is finalizing.
-
-   :c:func:`PyEval_RestoreThread` is a higher-level function which is always
-   available (even when threads have not been initialized).
-
-
-.. c:function:: void PyEval_ReleaseThread(PyThreadState *tstate)
-
-   Detach the :term:`attached thread state`.
-   The *tstate* argument, which must not be ``NULL``, is only used to check
-   that it represents the :term:`attached thread state` --- if it isn't, a fatal error is
-   reported.
-
-   :c:func:`PyEval_SaveThread` is a higher-level function which is always
-   available (even when threads have not been initialized).

-
-.. _sub-interpreter-support:
-
-Sub-interpreter support
-=======================
-
-While in most uses, you will only embed a single Python interpreter, there
-are cases where you need to create several independent interpreters in the
-same process and perhaps even in the same thread. Sub-interpreters allow
-you to do that.
-
-The "main" interpreter is the first one created when the runtime initializes.
-It is usually the only Python interpreter in a process.  Unlike sub-interpreters,
-the main interpreter has unique process-global responsibilities like signal
-handling.  It is also responsible for execution during runtime initialization and
-is usually the active interpreter during runtime finalization.  The
-:c:func:`PyInterpreterState_Main` function returns a pointer to its state.
-
-You can switch between sub-interpreters using the :c:func:`PyThreadState_Swap`
-function. You can create and destroy them using the following functions:
-
-
-.. c:type:: PyInterpreterConfig
-
-   Structure containing most parameters to configure a sub-interpreter.
-   Its values are used only in :c:func:`Py_NewInterpreterFromConfig` and
-   never modified by the runtime.
-
-   .. versionadded:: 3.12
-
-   Structure fields:
-
-   .. c:member:: int use_main_obmalloc
-
-      If this is ``0`` then the sub-interpreter will use its own
-      "object" allocator state.
-      Otherwise it will use (share) the main interpreter's.
-
-      If this is ``0`` then
-      :c:member:`~PyInterpreterConfig.check_multi_interp_extensions`
-      must be ``1`` (non-zero).
-      If this is ``1`` then :c:member:`~PyInterpreterConfig.gil`
-      must not be :c:macro:`PyInterpreterConfig_OWN_GIL`.
-
-   .. c:member:: int allow_fork
-
-      If this is ``0`` then the runtime will not support forking the
-      process in any thread where the sub-interpreter is currently active.
-      Otherwise fork is unrestricted.

-   table of loaded modules (``sys.modules``) and the module search path
-   (``sys.path``) are also separate.  The new environment has no ``sys.argv``
-   variable.  It has new standard I/O stream file objects ``sys.stdin``,
-   ``sys.stdout`` and ``sys.stderr`` (however these refer to the same underlying

-   is initialized.
-
-   Upon success, *tstate_p* will be set to the first :term:`thread state`
-   created in the new sub-interpreter.  This thread state is
-   :term:`attached <attached thread state>`.
-   Note that no actual thread is created; see the discussion of thread states
-   below.  If creation of the new interpreter is unsuccessful,
-   *tstate_p* is set to ``NULL``;
-   no exception is set since the exception state is stored in the
-   :term:`attached thread state`, which might not exist.
-
-   Like all other Python/C API functions, an :term:`attached thread state`
-   must be present before calling this function, but it might be detached upon
-   returning. On success, the returned thread state will be :term:`attached <attached thread state>`.
-   If the sub-interpreter is created with its own :term:`GIL` then the
-   :term:`attached thread state` of the calling interpreter will be detached.
-   When the function returns, the new interpreter's :term:`thread state`
-   will be :term:`attached <attached thread state>` to the current thread and
-   the previous interpreter's :term:`attached thread state` will remain detached.

-
-   .. index::
-      single: Py_FinalizeEx (C function)
-      single: Py_Initialize (C function)
-
-   Extension modules are shared between (sub-)interpreters as follows:
-
-   *  For modules using multi-phase initialization,
-      e.g. :c:func:`PyModule_FromDefAndSpec`, a separate module object is
-      created and initialized for each interpreter.
-      Only C-level static and global variables are shared between these
-      module objects.
-
-   *  For modules using single-phase initialization,
-      e.g. :c:func:`PyModule_Create`, the first time a particular extension
-      is imported, it is initialized normally, and a (shallow) copy of its
-      module's dictionary is squirreled away.
-      When the same extension is imported by another (sub-)interpreter, a new
-      module is initialized and filled with the contents of this copy; the
-      extension's ``init`` function is not called.
-      Objects in the module's dictionary thus end up shared across
-      (sub-)interpreters, which might cause unwanted behavior (see
-      `Bugs and caveats`_ below).
-
-      Note that this is different from what happens when an extension is
-      imported after the interpreter has been completely re-initialized by
-      calling :c:func:`Py_FinalizeEx` and :c:func:`Py_Initialize`; in that
-      case, the extension's ``initmodule`` function *is* called again.
-      As with multi-phase initialization, this means that only C-level static
-      and global variables are shared between these modules.

-
-   Create a new sub-interpreter.  This is essentially just a wrapper
-   around :c:func:`Py_NewInterpreterFromConfig` with a config that
-   preserves the existing behavior.  The result is an unisolated
-   sub-interpreter that shares the main interpreter's GIL, allows

-   All thread states associated with this interpreter are destroyed.
-
-   :c:func:`Py_FinalizeEx` will destroy all sub-interpreters that
-   haven't been explicitly destroyed at that point.
-
-
-.. _per-interpreter-gil:
-
-A Per-Interpreter GIL
----------------------
-
-Using :c:func:`Py_NewInterpreterFromConfig` you can create
-a sub-interpreter that is completely isolated from other interpreters,
-including having its own GIL.  The most important benefit of this
-isolation is that such an interpreter can execute Python code without
-being blocked by other interpreters or blocking any others.  Thus a
-single Python process can truly take advantage of multiple CPU cores
-when running Python code.  The isolation also encourages a different
-approach to concurrency than that of just using threads.
-(See :pep:`554` and :pep:`684`.)
-
-Using an isolated interpreter requires vigilance in preserving that
-isolation.  That especially means not sharing any objects or mutable
-state without guarantees about thread-safety.  Even objects that are
-otherwise immutable (e.g. ``None``, ``(1, 5)``) can't normally be shared
-because of the refcount.  One simple but less-efficient approach around
-this is to use a global lock around all use of some state (or object).
-Alternately, effectively immutable objects (like integers or strings)
-can be made safe in spite of their refcounts by making them :term:`immortal`.
-In fact, this has been done for the builtin singletons, small integers,
-and a number of other builtin objects.
-
-If you preserve isolation then you will have access to proper multi-core
-computing without the complications that come with free-threading.
-Failure to preserve isolation will expose you to the full consequences
-of free-threading, including races and hard-to-debug crashes.
-
-Aside from that, one of the main challenges of using multiple isolated
-interpreters is how to communicate between them safely (not break
-isolation) and efficiently.  The runtime and stdlib do not provide
-any standard approach to this yet.  A future stdlib module would help
-mitigate the effort of preserving isolation and expose effective tools
-for communicating (and sharing) data between interpreters.
-
-.. versionadded:: 3.12
-
-
-Bugs and caveats
-----------------
-
-Because sub-interpreters (and the main interpreter) are part of the same
-process, the insulation between them isn't perfect --- for example, using
-low-level file operations like  :func:`os.close` they can
-(accidentally or maliciously) affect each other's open files.  Because of the
-way extensions are shared between (sub-)interpreters, some extensions may not
-work properly; this is especially likely when using single-phase initialization
-or (static) global variables.
-It is possible to insert objects created in one sub-interpreter into
-a namespace of another (sub-)interpreter; this should be avoided if possible.
-
-Special care should be taken to avoid sharing user-defined functions,
-methods, instances or classes between sub-interpreters, since import
-operations executed by such objects may affect the wrong (sub-)interpreter's
-dictionary of loaded modules. It is equally important to avoid sharing
-objects from which the above are reachable.
-
-Also note that combining this functionality with ``PyGILState_*`` APIs
-is delicate, because these APIs assume a bijection between Python thread states
-and OS-level threads, an assumption broken by the presence of sub-interpreters.
-It is highly recommended that you don't switch sub-interpreters between a pair
-of matching :c:func:`PyGILState_Ensure` and :c:func:`PyGILState_Release` calls.
-Furthermore, extensions (such as :mod:`ctypes`) using these APIs to allow calling
-of Python code from non-Python created threads will probably be broken when using
-sub-interpreters.
-
-
-Asynchronous Notifications
-==========================
-
-A mechanism is provided to make asynchronous notifications to the main
-interpreter thread.  These notifications take the form of a function
-pointer and a void pointer argument.
-
-
-.. c:function:: int Py_AddPendingCall(int (*func)(void *), void *arg)
-
-   Schedule a function to be called from the main interpreter thread.  On
-   success, ``0`` is returned and *func* is queued for being called in the
-   main thread.  On failure, ``-1`` is returned without setting any exception.
-
-   When successfully queued, *func* will be *eventually* called from the
-   main interpreter thread with the argument *arg*.  It will be called
-   asynchronously with respect to normally running Python code, but with
-   both these conditions met:
-
-   * on a :term:`bytecode` boundary;
-   * with the main thread holding an :term:`attached thread state`
-     (*func* can therefore use the full C API).
-
-   *func* must return ``0`` on success, or ``-1`` on failure with an exception
-   set.  *func* won't be interrupted to perform another asynchronous
-   notification recursively, but it can still be interrupted to switch
-   threads if the :term:`thread state <attached thread state>` is detached.
-
-   This function doesn't need an :term:`attached thread state`. However, to call this
-   function in a subinterpreter, the caller must have an :term:`attached thread state`.
-   Otherwise, the function *func* can be scheduled to be called from the wrong interpreter.
-
-   .. warning::
-      This is a low-level function, only useful for very special cases.
-      There is no guarantee that *func* will be called as quick as
-      possible.  If the main thread is busy executing a system call,
-      *func* won't be called before the system call returns.  This
-      function is generally **not** suitable for calling Python code from
-      arbitrary C threads.  Instead, use the :ref:`PyGILState API<gilstate>`.
-
-   .. versionadded:: 3.1
-
-   .. versionchanged:: 3.9
-      If this function is called in a subinterpreter, the function *func* is
-      now scheduled to be called from the subinterpreter, rather than being
-      called from the main interpreter. Each subinterpreter now has its own
-      list of scheduled calls.
-
-   .. versionchanged:: 3.12
-      This function now always schedules *func* to be run in the main
-      interpreter.

-Profiling and Tracing
-=====================
-
-.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
-
-
-The Python interpreter provides some low-level support for attaching profiling
-and execution tracing facilities.  These are used for profiling, debugging, and
-coverage analysis tools.
-
-This C interface allows the profiling or tracing code to avoid the overhead of
-calling through Python-level callable objects, making a direct C function call
-instead.  The essential attributes of the facility have not changed; the
-interface allows trace functions to be installed per-thread, and the basic
-events reported to the trace function are the same as had been reported to the
-Python-level trace functions in previous versions.
-
-
-.. c:type:: int (*Py_tracefunc)(PyObject *obj, PyFrameObject *frame, int what, PyObject *arg)
-
-   The type of the trace function registered using :c:func:`PyEval_SetProfile` and
-   :c:func:`PyEval_SetTrace`. The first parameter is the object passed to the
-   registration function as *obj*, *frame* is the frame object to which the event
-   pertains, *what* is one of the constants :c:data:`PyTrace_CALL`,
-   :c:data:`PyTrace_EXCEPTION`, :c:data:`PyTrace_LINE`, :c:data:`PyTrace_RETURN`,
-   :c:data:`PyTrace_C_CALL`, :c:data:`PyTrace_C_EXCEPTION`, :c:data:`PyTrace_C_RETURN`,
-   or :c:data:`PyTrace_OPCODE`, and *arg* depends on the value of *what*:

-
-.. c:var:: int PyTrace_CALL
-
-   The value of the *what* parameter to a :c:type:`Py_tracefunc` function when a new
-   call to a function or method is being reported, or a new entry into a generator.
-   Note that the creation of the iterator for a generator function is not reported
-   as there is no control transfer to the Python bytecode in the corresponding
-   frame.
-
-
-.. c:var:: int PyTrace_EXCEPTION
-
-   The value of the *what* parameter to a :c:type:`Py_tracefunc` function when an
-   exception has been raised.  The callback function is called with this value for
-   *what* when after any bytecode is processed after which the exception becomes
-   set within the frame being executed.  The effect of this is that as exception
-   propagation causes the Python stack to unwind, the callback is called upon
-   return to each frame as the exception propagates.  Only trace functions receives
-   these events; they are not needed by the profiler.
-
-
-.. c:var:: int PyTrace_LINE
-
-   The value passed as the *what* parameter to a :c:type:`Py_tracefunc` function
-   (but not a profiling function) when a line-number event is being reported.
-   It may be disabled for a frame by setting :attr:`~frame.f_trace_lines` to
-   *0* on that frame.
-
-
-.. c:var:: int PyTrace_RETURN
-
-   The value for the *what* parameter to :c:type:`Py_tracefunc` functions when a
-   call is about to return.
-
-

-
-   The value for the *what* parameter to :c:type:`Py_tracefunc` functions when a C

-
-   The value for the *what* parameter to :c:type:`Py_tracefunc` functions when a C
-   function has raised an exception.
-
-
-.. c:var:: int PyTrace_C_RETURN
-
-   The value for the *what* parameter to :c:type:`Py_tracefunc` functions when a C
-   function has returned.
-
-
-.. c:var:: int PyTrace_OPCODE
-
-   The value for the *what* parameter to :c:type:`Py_tracefunc` functions (but not
-   profiling functions) when a new opcode is about to be executed.  This event is
-   not emitted by default: it must be explicitly requested by setting
-   :attr:`~frame.f_trace_opcodes` to *1* on the frame.
-
-
-.. c:function:: void PyEval_SetProfile(Py_tracefunc func, PyObject *obj)
-
-   Set the profiler function to *func*.  The *obj* parameter is passed to the
-   function as its first parameter, and may be any Python object, or ``NULL``.  If
-   the profile function needs to maintain state, using a different value for *obj*
-   for each thread provides a convenient and thread-safe place to store it.  The
-   profile function is called for all monitored events except :c:data:`PyTrace_LINE`
-   :c:data:`PyTrace_OPCODE` and :c:data:`PyTrace_EXCEPTION`.
-
-   See also the :func:`sys.setprofile` function.
-
-   The caller must have an :term:`attached thread state`.
-
-.. c:function:: void PyEval_SetProfileAllThreads(Py_tracefunc func, PyObject *obj)
-
-   Like :c:func:`PyEval_SetProfile` but sets the profile function in all running threads
-   belonging to the current interpreter instead of the setting it only on the current thread.
-
-   The caller must have an :term:`attached thread state`.
-
-   As :c:func:`PyEval_SetProfile`, this function ignores any exceptions raised while
-   setting the profile functions in all threads.
-
-.. versionadded:: 3.12
-
-
-.. c:function:: void PyEval_SetTrace(Py_tracefunc func, PyObject *obj)
-
-   Set the tracing function to *func*.  This is similar to
-   :c:func:`PyEval_SetProfile`, except the tracing function does receive line-number
-   events and per-opcode events, but does not receive any event related to C function
-   objects being called.  Any trace function registered using :c:func:`PyEval_SetTrace`
-   will not receive :c:data:`PyTrace_C_CALL`, :c:data:`PyTrace_C_EXCEPTION` or
-   :c:data:`PyTrace_C_RETURN` as a value for the *what* parameter.
-
-   See also the :func:`sys.settrace` function.
-
-   The caller must have an :term:`attached thread state`.
-
-.. c:function:: void PyEval_SetTraceAllThreads(Py_tracefunc func, PyObject *obj)
-
-   Like :c:func:`PyEval_SetTrace` but sets the tracing function in all running threads
-   belonging to the current interpreter instead of the setting it only on the current thread.
-
-   The caller must have an :term:`attached thread state`.
-
-   As :c:func:`PyEval_SetTrace`, this function ignores any exceptions raised while

-
-   The type of the trace function registered using :c:func:`PyRefTracer_SetTracer`.

-   is set to :c:data:`PyRefTracer_CREATE`) or about to be destroyed (when **event**
-   is set to :c:data:`PyRefTracer_DESTROY`). The **data** argument is the opaque pointer
-   that was provided when :c:func:`PyRefTracer_SetTracer` was called.
-
-   If a new tracing function is registered replacing the current a call to the
-   trace function will be made with the object set to **NULL** and **event** set to

-
-   .. versionadded:: 3.14
-
-.. c:function:: int PyRefTracer_SetTracer(PyRefTracer tracer, void *data)
-
-   Register a reference tracer function. The function will be called when a new
-   Python has been created or when an object is going to be destroyed. If
-   **data** is provided it must be an opaque pointer that will be provided when
-   the tracer function is called. Return ``0`` on success. Set an exception and
-   return ``-1`` on error.
-
-   Not that tracer functions **must not** create Python objects inside or
-   otherwise the call will be re-entrant. The tracer also **must not** clear
-   any existing exception or set an exception.  A :term:`thread state` will be active
-   every time the tracer function is called.
-
-   There must be an :term:`attached thread state` when calling this function.
-
-   If another tracer function was already registered, the old function will be
-   called with **event** set to :c:data:`PyRefTracer_TRACKER_REMOVED` just before

-Thread Local Storage Support
-============================
-
-.. sectionauthor:: Masayuki Yamamoto <ma3yuki.8mamo10@gmail.com>
-
-The Python interpreter provides low-level support for thread-local storage
-(TLS) which wraps the underlying native TLS implementation to support the
-Python-level thread local storage API (:class:`threading.local`).  The
-CPython C level APIs are similar to those offered by pthreads and Windows:
-use a thread key and functions to associate a :c:expr:`void*` value per
-thread.
-
-A :term:`thread state` does *not* need to be :term:`attached <attached thread state>`
-when calling these functions; they supply their own locking.
-
-Note that :file:`Python.h` does not include the declaration of the TLS APIs,
-you need to include :file:`pythread.h` to use thread-local storage.
-
-.. note::
-   None of these API functions handle memory management on behalf of the
-   :c:expr:`void*` values.  You need to allocate and deallocate them yourself.
-   If the :c:expr:`void*` values happen to be :c:expr:`PyObject*`, these
-   functions don't do refcount operations on them either.
-
-.. _thread-specific-storage-api:
-
-Thread Specific Storage (TSS) API
----------------------------------
-
-TSS API is introduced to supersede the use of the existing TLS API within the
-CPython interpreter.  This API uses a new type :c:type:`Py_tss_t` instead of
-:c:expr:`int` to represent thread keys.
-
-.. versionadded:: 3.7
-
-.. seealso:: "A New C-API for Thread-Local Storage in CPython" (:pep:`539`)
-
-
-.. c:type:: Py_tss_t
-
-   This data structure represents the state of a thread key, the definition of
-   which may depend on the underlying TLS implementation, and it has an
-   internal field representing the key's initialization state.  There are no
-   public members in this structure.
-
-   When :ref:`Py_LIMITED_API <stable>` is not defined, static allocation of
-   this type by :c:macro:`Py_tss_NEEDS_INIT` is allowed.
-
-
-.. c:macro:: Py_tss_NEEDS_INIT
-
-   This macro expands to the initializer for :c:type:`Py_tss_t` variables.
-   Note that this macro won't be defined with :ref:`Py_LIMITED_API <stable>`.
-
-
-Dynamic Allocation
-~~~~~~~~~~~~~~~~~~
-
-Dynamic allocation of the :c:type:`Py_tss_t`, required in extension modules
-built with :ref:`Py_LIMITED_API <stable>`, where static allocation of this type
-is not possible due to its implementation being opaque at build time.
-
-
-.. c:function:: Py_tss_t* PyThread_tss_alloc()
-
-   Return a value which is the same state as a value initialized with
-   :c:macro:`Py_tss_NEEDS_INIT`, or ``NULL`` in the case of dynamic allocation
-   failure.
-
-
-.. c:function:: void PyThread_tss_free(Py_tss_t *key)
-
-   Free the given *key* allocated by :c:func:`PyThread_tss_alloc`, after
-   first calling :c:func:`PyThread_tss_delete` to ensure any associated
-   thread locals have been unassigned. This is a no-op if the *key*
-   argument is ``NULL``.
-
-   .. note::
-      A freed key becomes a dangling pointer. You should reset the key to
-      ``NULL``.
-
-
-Methods
-~~~~~~~
-
-The parameter *key* of these functions must not be ``NULL``.  Moreover, the
-behaviors of :c:func:`PyThread_tss_set` and :c:func:`PyThread_tss_get` are
-undefined if the given :c:type:`Py_tss_t` has not been initialized by
-:c:func:`PyThread_tss_create`.
-
-
-.. c:function:: int PyThread_tss_is_created(Py_tss_t *key)
-
-   Return a non-zero value if the given :c:type:`Py_tss_t` has been initialized
-   by :c:func:`PyThread_tss_create`.
-
-
-.. c:function:: int PyThread_tss_create(Py_tss_t *key)
-
-   Return a zero value on successful initialization of a TSS key.  The behavior
-   is undefined if the value pointed to by the *key* argument is not
-   initialized by :c:macro:`Py_tss_NEEDS_INIT`.  This function can be called
-   repeatedly on the same key -- calling it on an already initialized key is a
-   no-op and immediately returns success.
-
-
-.. c:function:: void PyThread_tss_delete(Py_tss_t *key)
-
-   Destroy a TSS key to forget the values associated with the key across all
-   threads, and change the key's initialization state to uninitialized.  A
-   destroyed key is able to be initialized again by
-   :c:func:`PyThread_tss_create`. This function can be called repeatedly on
-   the same key -- calling it on an already destroyed key is a no-op.
-
-
-.. c:function:: int PyThread_tss_set(Py_tss_t *key, void *value)
-
-   Return a zero value to indicate successfully associating a :c:expr:`void*`
-   value with a TSS key in the current thread.  Each thread has a distinct
-   mapping of the key to a :c:expr:`void*` value.
-
-
-.. c:function:: void* PyThread_tss_get(Py_tss_t *key)
-
-   Return the :c:expr:`void*` value associated with a TSS key in the current
-   thread.  This returns ``NULL`` if no value is associated with the key in the
-   current thread.
-
-
-.. _thread-local-storage-api:
-
-Thread Local Storage (TLS) API
-------------------------------
-
-.. deprecated:: 3.7
-   This API is superseded by
-   :ref:`Thread Specific Storage (TSS) API <thread-specific-storage-api>`.
-
-.. note::
-   This version of the API does not support platforms where the native TLS key
-   is defined in a way that cannot be safely cast to ``int``.  On such platforms,
-   :c:func:`PyThread_create_key` will return immediately with a failure status,
-   and the other TLS functions will all be no-ops on such platforms.
-
-Due to the compatibility problem noted above, this version of the API should not
-be used in new code.
-
-.. c:function:: int PyThread_create_key()
-.. c:function:: void PyThread_delete_key(int key)
-.. c:function:: int PyThread_set_key_value(int key, void *value)
-.. c:function:: void* PyThread_get_key_value(int key)
-.. c:function:: void PyThread_delete_key_value(int key)
-.. c:function:: void PyThread_ReInitTLS()
-
-Synchronization Primitives
-==========================
-
-The C-API provides a basic mutual exclusion lock.
-
-.. c:type:: PyMutex
-
-   A mutual exclusion lock.  The :c:type:`!PyMutex` should be initialized to
-   zero to represent the unlocked state.  For example::
-
-      PyMutex mutex = {0};
-
-   Instances of :c:type:`!PyMutex` should not be copied or moved.  Both the
-   contents and address of a :c:type:`!PyMutex` are meaningful, and it must
-   remain at a fixed, writable location in memory.
-
-   .. note::
-
-      A :c:type:`!PyMutex` currently occupies one byte, but the size should be
-      considered unstable.  The size may change in future Python releases
-      without a deprecation period.
-
-   .. versionadded:: 3.13
-
-.. c:function:: void PyMutex_Lock(PyMutex *m)
-
-   Lock mutex *m*.  If another thread has already locked it, the calling
-   thread will block until the mutex is unlocked.  While blocked, the thread
-   will temporarily detach the :term:`thread state <attached thread state>` if one exists.
-
-   .. versionadded:: 3.13
-
-.. c:function:: void PyMutex_Unlock(PyMutex *m)
-
-   Unlock mutex *m*. The mutex must be locked --- otherwise, the function will
-   issue a fatal error.
-
-   .. versionadded:: 3.13
-
-.. c:function:: int PyMutex_IsLocked(PyMutex *m)
-
-   Returns non-zero if the mutex *m* is currently locked, zero otherwise.
-
-   .. note::
-
-      This function is intended for use in assertions and debugging only and
-      should not be used to make concurrency control decisions, as the lock
-      state may change immediately after the check.
-
-   .. versionadded:: 3.14
-
-.. _python-critical-section-api:
-
-Python Critical Section API
----------------------------
-
-The critical section API provides a deadlock avoidance layer on top of
-per-object locks for :term:`free-threaded <free threading>` CPython.  They are
-intended to replace reliance on the :term:`global interpreter lock`, and are
-no-ops in versions of Python with the global interpreter lock.
-
-Critical sections are intended to be used for custom types implemented
-in C-API extensions. They should generally not be used with built-in types like
-:class:`list` and :class:`dict` because their public C-APIs
-already use critical sections internally, with the notable
-exception of :c:func:`PyDict_Next`, which requires critical section
-to be acquired externally.
-
-Critical sections avoid deadlocks by implicitly suspending active critical
-sections, hence, they do not provide exclusive access such as provided by
-traditional locks like :c:type:`PyMutex`.  When a critical section is started,
-the per-object lock for the object is acquired. If the code executed inside the
-critical section calls C-API functions then it can suspend the critical section thereby
-releasing the per-object lock, so other threads can acquire the per-object lock
-for the same object.
-
-Variants that accept :c:type:`PyMutex` pointers rather than Python objects are also
-available. Use these variants to start a critical section in a situation where
-there is no :c:type:`PyObject` -- for example, when working with a C type that
-does not extend or wrap :c:type:`PyObject` but still needs to call into the C
-API in a manner that might lead to deadlocks.
-
-The functions and structs used by the macros are exposed for cases
-where C macros are not available. They should only be used as in the
-given macro expansions. Note that the sizes and contents of the structures may
-change in future Python versions.
-
-.. note::
-
-   Operations that need to lock two objects at once must use
-   :c:macro:`Py_BEGIN_CRITICAL_SECTION2`.  You *cannot* use nested critical
-   sections to lock more than one object at once, because the inner critical
-   section may suspend the outer critical sections.  This API does not provide
-   a way to lock more than two objects at once.
-
-Example usage::
-
-   static PyObject *
-   set_field(MyObject *self, PyObject *value)
-   {
-      Py_BEGIN_CRITICAL_SECTION(self);
-      Py_SETREF(self->field, Py_XNewRef(value));
-      Py_END_CRITICAL_SECTION();
-      Py_RETURN_NONE;
-   }
-
-In the above example, :c:macro:`Py_SETREF` calls :c:macro:`Py_DECREF`, which
-can call arbitrary code through an object's deallocation function.  The critical
-section API avoids potential deadlocks due to reentrancy and lock ordering
-by allowing the runtime to temporarily suspend the critical section if the
-code triggered by the finalizer blocks and calls :c:func:`PyEval_SaveThread`.
-
-.. c:macro:: Py_BEGIN_CRITICAL_SECTION(op)
-
-   Acquires the per-object lock for the object *op* and begins a
-   critical section.
-
-   In the free-threaded build, this macro expands to::
-
-      {
-          PyCriticalSection _py_cs;
-          PyCriticalSection_Begin(&_py_cs, (PyObject*)(op))
-
-   In the default build, this macro expands to ``{``.
-
-   .. versionadded:: 3.13
-
-.. c:macro:: Py_BEGIN_CRITICAL_SECTION_MUTEX(m)

-     {
-          PyCriticalSection _py_cs;
-          PyCriticalSection_BeginMutex(&_py_cs, m)
-
-   Note that unlike :c:macro:`Py_BEGIN_CRITICAL_SECTION`, there is no cast for

-
-.. c:macro:: Py_END_CRITICAL_SECTION()
-
-   Ends the critical section and releases the per-object lock.
-
-   In the free-threaded build, this macro expands to::

-      }
-
-   In the default build, this macro expands to ``}``.
-
-   .. versionadded:: 3.13
-
-.. c:macro:: Py_BEGIN_CRITICAL_SECTION2(a, b)
-
-   Acquires the per-objects locks for the objects *a* and *b* and begins a
-   critical section.  The locks are acquired in a consistent order (lowest
-   address first) to avoid lock ordering deadlocks.
-
-   In the free-threaded build, this macro expands to::
-
-      {
-          PyCriticalSection2 _py_cs2;
-          PyCriticalSection2_Begin(&_py_cs2, (PyObject*)(a), (PyObject*)(b))

-Delaying main module execution
-==============================
 
-In some embedding use cases, it may be desirable to separate interpreter initialization
-from the execution of the main module.
+Multi-Phase Initialization Private Provisional API
+==================================================
+
+This section is a private provisional API introducing multi-phase
+initialization, the core feature of :pep:`432`:
+
+* "Core" initialization phase, "bare minimum Python":
+
+  * Builtin types;
+  * Builtin exceptions;
+  * Builtin and frozen modules;
+  * The :mod:`sys` module is only partially initialized
+    (ex: :data:`sys.path` doesn't exist yet).
+
+* "Main" initialization phase, Python is fully initialized:
+
+  * Install and configure :mod:`importlib`;
+  * Apply the :ref:`Path Configuration <init-path-config>`;
+  * Install signal handlers;
+  * Finish :mod:`sys` module initialization (ex: create :data:`sys.stdout`
+    and :data:`sys.path`);
+  * Enable optional features like :mod:`faulthandler` and :mod:`tracemalloc`;
+  * Import the :mod:`site` module;
+  * etc.
+
+Private provisional API:
+
+.. c:member:: int PyConfig._init_main
+
+   If set to ``0``, :c:func:`Py_InitializeFromConfig` stops at the "Core"
+   initialization phase.
+
+.. c:function:: PyStatus _Py_InitializeMain(void)
+
+   Move to the "Main" initialization phase, finish the Python initialization.
+
+No module is imported during the "Core" phase and the ``importlib`` module is
+not configured: the :ref:`Path Configuration <init-path-config>` is only
+applied during the "Main" phase. It may allow to customize Python in Python to
+override or tune the :ref:`Path Configuration <init-path-config>`, maybe
+install a custom :data:`sys.meta_path` importer or an import hook, etc.
+
+It may become possible to calculate the :ref:`Path Configuration
+<init-path-config>` in Python, after the Core phase and before the Main phase,
+which is one of the :pep:`432` motivation.
+
+The "Core" phase is not properly defined: what should be and what should
+not be available at this phase is not specified yet. The API is marked
+as private and provisional: the API can be modified or even be removed
+anytime until a proper public API is designed.
+
+Example running Python code between "Core" and "Main" initialization
+phases::
+
+    void init_python(void)
+    {
+        PyStatus status;
+
+        PyConfig config;
+        PyConfig_InitPythonConfig(&config);
+        config._init_main = 0;
+
+        /* ... customize 'config' configuration ... */
+
+        status = Py_InitializeFromConfig(&config);
+        PyConfig_Clear(&config);
+        if (PyStatus_Exception(status)) {
+            Py_ExitStatusException(status);
+        }
+
+        /* Use sys.stderr because sys.stdout is only created
+           by _Py_InitializeMain() */
+        int res = PyRun_SimpleString(
+            "import sys; "
+            "print('Run Python code before _Py_InitializeMain', "
+                   "file=sys.stderr)");
+        if (res < 0) {
+            exit(1);
+        }
+
+        /* ... put more configuration code here ... */
 
-This separation can be achieved by setting ``PyConfig.run_command`` to the empty
-string during initialization (to prevent the interpreter from dropping into the
-interactive prompt), and then subsequently executing the desired main module
-code using ``__main__.__dict__`` as the global namespace.
+        status = _Py_InitializeMain();
+        if (PyStatus_Exception(status)) {
+            Py_ExitStatusException(status);

+
+Before Python initialization
+----------------------------
+
+In an application embedding Python, the :c:func:`Py_Initialize` function must
+be called before using any other Python/C API functions; with the exception of
+a few functions and the :ref:`global configuration variables
+<global-conf-vars>`.
+
+The following functions can be safely called before Python is initialized:
+

+  * :c:func:`Py_InitializeFromConfig`
+  * :c:func:`Py_BytesMain`

+
+   Despite their apparent similarity to some of the functions listed above,

+
+Global configuration variables
+------------------------------
+
+Python has variables for the global configuration to control different features
+and options. By default, these flags are controlled by :ref:`command line
+options <using-on-interface-options>`.
+
+When a flag is set by an option, the value of the flag is the number of times
+that the option was set. For example, ``-b`` sets :c:data:`Py_BytesWarningFlag`
+to 1 and ``-bb`` sets :c:data:`Py_BytesWarningFlag` to 2.
+
+
+.. c:var:: int Py_BytesWarningFlag
+
+   This API is kept for backward compatibility: setting
+   :c:member:`PyConfig.bytes_warning` should be used instead, see :ref:`Python
+   Initialization Configuration <init-config>`.
+
+   Issue a warning when comparing :class:`bytes` or :class:`bytearray` with
+   :class:`str` or :class:`bytes` with :class:`int`.  Issue an error if greater
+   or equal to ``2``.

+
+   Initialize the Python interpreter.  In an application embedding Python,
+   this should be called before using any other Python/C API functions; see
+   :ref:`Before Python Initialization <pre-init-safe>` for the few exceptions.
+
+   This initializes the table of loaded modules (``sys.modules``), and creates
+   the fundamental modules :mod:`builtins`, :mod:`__main__` and :mod:`sys`.
+   It also initializes the module search path (``sys.path``). It does not set
+   ``sys.argv``; use the :ref:`Python Initialization Configuration <init-config>`
+   API for that. This is a no-op when called for a second time (without calling
+   :c:func:`Py_FinalizeEx` first).  There is no return value; it is a fatal
+   error if the initialization fails.
+
+   Use :c:func:`Py_InitializeFromConfig` to customize the
+   :ref:`Python Initialization Configuration <init-config>`.
+
+   .. note::
+      On Windows, changes the console mode from ``O_TEXT`` to ``O_BINARY``,
+      which will also affect non-Python uses of the console using the C Runtime.
+
+
+.. c:function:: void Py_InitializeEx(int initsigs)
+
+   This function works like :c:func:`Py_Initialize` if *initsigs* is ``1``. If
+   *initsigs* is ``0``, it skips initialization registration of signal handlers,
+   which may be useful when CPython is embedded as part of a larger application.
+
+   Use :c:func:`Py_InitializeFromConfig` to customize the
+   :ref:`Python Initialization Configuration <init-config>`.
+
+
+.. c:function:: PyStatus Py_InitializeFromConfig(const PyConfig *config)
+
+   Initialize Python from *config* configuration, as described in
+   :ref:`init-from-config`.
+
+   See the :ref:`init-config` section for details on pre-initializing the
+   interpreter, populating the runtime configuration structure, and querying
+   the returned status structure.
+
+
+.. c:function:: int Py_IsInitialized()
+
+   Return true (nonzero) when the Python interpreter has been initialized, false
+   (zero) if not.  After :c:func:`Py_FinalizeEx` is called, this returns false until
+   :c:func:`Py_Initialize` is called again.
+
+   .. versionchanged:: 3.15
+      This function no longer returns true until initialization has fully
+      completed, including import of the :mod:`site` module.  Previously it
+      could return true while :c:func:`Py_Initialize` was still running.
+
+
+.. c:function:: int Py_IsFinalizing()
+
+   Return true (non-zero) if the main Python interpreter is
+   :term:`shutting down <interpreter shutdown>`. Return false (zero) otherwise.
+
+   .. versionadded:: 3.13
+
+
+.. c:function:: int Py_FinalizeEx()
+
+   Undo all initializations made by :c:func:`Py_Initialize` and subsequent use of
+   Python/C API functions, and destroy all sub-interpreters (see
+   :c:func:`Py_NewInterpreter` below) that were created and not yet destroyed since
+   the last call to :c:func:`Py_Initialize`.  This is a no-op when called for a second
+   time (without calling :c:func:`Py_Initialize` again first).
+
+   Since this is the reverse of :c:func:`Py_Initialize`, it should be called
+   in the same thread with the same interpreter active.  That means
+   the main thread and the main interpreter.
+   This should never be called while :c:func:`Py_RunMain` is running.
+
+   Normally the return value is ``0``.
+   If there were errors during finalization (flushing buffered data),
+   ``-1`` is returned.
+
+   Note that Python will do a best effort at freeing all memory allocated by the Python
+   interpreter.  Therefore, any C-Extension should make sure to correctly clean up all
+   of the previously allocated PyObjects before using them in subsequent calls to
+   :c:func:`Py_Initialize`.  Otherwise it could introduce vulnerabilities and incorrect
+   behavior.
+
+   This function is provided for a number of reasons.  An embedding application
+   might want to restart Python without having to restart the application itself.
+   An application that has loaded the Python interpreter from a dynamically
+   loadable library (or DLL) might want to free all memory allocated by Python
+   before unloading the DLL. During a hunt for memory leaks in an application a
+   developer might want to free all memory allocated by Python before exiting from
+   the application.
+
+   **Bugs and caveats:** The destruction of modules and objects in modules is done
+   in random order; this may cause destructors (:meth:`~object.__del__` methods) to fail
+   when they depend on other objects (even functions) or modules.  Dynamically
+   loaded extension modules loaded by Python are not unloaded.  Small amounts of
+   memory allocated by the Python interpreter may not be freed (if you find a leak,
+   please report it).  Memory tied up in circular references between objects is not
+   freed.  Interned strings will all be deallocated regardless of their reference count.
+   Some memory allocated by extension modules may not be freed.  Some extensions may not
+   work properly if their initialization routine is called more than once; this can
+   happen if an application calls :c:func:`Py_Initialize` and :c:func:`Py_FinalizeEx`
+   more than once.  :c:func:`Py_FinalizeEx` must not be called recursively from
+   within itself.  Therefore, it must not be called by any code that may be run
+   as part of the interpreter shutdown process, such as :py:mod:`atexit`
+   handlers, object finalizers, or any code that may be run while flushing the
+   stdout and stderr files.

+   disregards the return value.
+
+
+.. c:function:: int Py_BytesMain(int argc, char **argv)
+
+   Similar to :c:func:`Py_Main` but *argv* is an array of bytes strings,
+   allowing the calling application to delegate the text decoding step to
+   the CPython runtime.
+
+   .. versionadded:: 3.8
+
+
+.. c:function:: int Py_Main(int argc, wchar_t **argv)
+
+   The main program for the standard interpreter, encapsulating a full
+   initialization/finalization cycle, as well as additional
+   behaviour to implement reading configurations settings from the environment
+   and command line, and then executing ``__main__`` in accordance with
+   :ref:`using-on-cmdline`.
+
+   This is made available for programs which wish to support the full CPython
+   command line interface, rather than just embedding a Python runtime in a
+   larger application.
+
+   The *argc* and *argv* parameters are similar to those which are passed to a
+   C program's :c:func:`main` function, except that the *argv* entries are first
+   converted to ``wchar_t`` using :c:func:`Py_DecodeLocale`. It is also
+   important to note that the argument list entries may be modified to point to
+   strings other than those passed in (however, the contents of the strings
+   pointed to by the argument list are not modified).
+
+   The return value is ``2`` if the argument list does not represent a valid
+   Python command line, and otherwise the same as :c:func:`Py_RunMain`.
+
+   In terms of the CPython runtime configuration APIs documented in the
+   :ref:`runtime configuration <init-config>` section (and without accounting
+   for error handling), ``Py_Main`` is approximately equivalent to::
+
+      PyConfig config;
+      PyConfig_InitPythonConfig(&config);
+      PyConfig_SetArgv(&config, argc, argv);
+      Py_InitializeFromConfig(&config);
+      PyConfig_Clear(&config);
+
+      Py_RunMain();
+
+   In normal usage, an embedding application will call this function
+   *instead* of calling :c:func:`Py_Initialize`, :c:func:`Py_InitializeEx` or
+   :c:func:`Py_InitializeFromConfig` directly, and all settings will be applied
+   as described elsewhere in this documentation. If this function is instead
+   called *after* a preceding runtime initialization API call, then exactly
+   which environmental and command line configuration settings will be updated
+   is version dependent (as it depends on which settings correctly support
+   being modified after they have already been set once when the runtime was
+   first initialized).
+
+
+.. c:function:: int Py_RunMain(void)
+
+   Executes the main module in a fully configured CPython runtime.
+
+   Executes the command (:c:member:`PyConfig.run_command`), the script
+   (:c:member:`PyConfig.run_filename`) or the module
+   (:c:member:`PyConfig.run_module`) specified on the command line or in the
+   configuration. If none of these values are set, runs the interactive Python
+   prompt (REPL) using the ``__main__`` module's global namespace.
+
+   If :c:member:`PyConfig.inspect` is not set (the default), the return value
+   will be ``0`` if the interpreter exits normally (that is, without raising
+   an exception), the exit status of an unhandled :exc:`SystemExit`, or ``1``
+   for any other unhandled exception.
+
+   If :c:member:`PyConfig.inspect` is set (such as when the :option:`-i` option
+   is used), rather than returning when the interpreter exits, execution will
+   instead resume in an interactive Python prompt (REPL) using the ``__main__``
+   module's global namespace. If the interpreter exited with an exception, it
+   is immediately raised in the REPL session. The function return value is
+   then determined by the way the *REPL session* terminates: ``0``, ``1``, or
+   the status of a :exc:`SystemExit`, as specified above.
+
+   This function always finalizes the Python interpreter before it returns.
+
+   See :ref:`Python Configuration <init-python-config>` for an example of a
+   customized Python that always runs in isolated mode using
+   :c:func:`Py_RunMain`.
+
+.. c:function:: int PyUnstable_AtExit(PyInterpreterState *interp, void (*func)(void *), void *data)
+
+   Register an :mod:`atexit` callback for the target interpreter *interp*.

+
+
+.. _cautions-regarding-runtime-finalization:
+
+Cautions regarding interpreter finalization
+-------------------------------------------
+
+In the late stage of :term:`interpreter shutdown`, after attempting to wait for
+non-daemon threads to exit (though this can be interrupted by
+:class:`KeyboardInterrupt`) and running the :mod:`atexit` functions, the runtime
+is marked as finalizing, meaning that :c:func:`Py_IsFinalizing` and
+:func:`sys.is_finalizing` return true.  At this point, only the finalization
+thread (the thread that initiated finalization; this is typically the main thread)
+is allowed to :term:`attach <attached thread state>` a thread state.
+
+Other threads that attempt to attach during finalization, either explicitly
+(such as via :c:func:`PyThreadState_Ensure` or :c:macro:`Py_END_ALLOW_THREADS`)
+or implicitly (such as in-between bytecode instructions), will enter a
+**permanently blocked state**. Generally, this is harmless, but this can
+result in deadlocks. For example, a thread may be permanently blocked while
+holding a lock, meaning that the finalization thread can never acquire that
+lock.
+
+Prior to CPython 3.13, the thread would exit instead of hanging,
+which led to other issues (see the warning note at
+:c:func:`PyThread_exit_thread`).
+
+Gross? Yes. Starting in Python 3.15, there are a number of C APIs that make
+it possible to avoid these issues by temporarily preventing finalization:
+
+.. _interpreter-guards:
+
+.. seealso::
+
+   :pep:`788` explains the design, motivation and rationale
+   for these APIs.
+
+.. c:type:: PyInterpreterGuard
+
+   An opaque interpreter guard structure.
+
+   By holding an interpreter guard, the caller can ensure that the interpreter
+   will not finalize until the guard is closed (through
+   :c:func:`PyInterpreterGuard_Close`).
+
+   When a guard is held, a thread attempting to finalize the interpreter will
+   block until the guard is closed before starting finalization.
+   After finalization has started, threads are forever unable to acquire
+   guards for that interpreter. This means that if you forget to close an
+   interpreter guard, the process will **permanently hang** during
+   finalization!
+
+   Holding a guard for an interpreter is similar to holding a
+   :term:`strong reference` to a Python object, except finalization does not happen
+   automatically after all guards are released: it requires an explicit
+   :c:func:`Py_EndInterpreter` call.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: PyInterpreterGuard *PyInterpreterGuard_FromCurrent(void)
+
+   Create a finalization guard for the current interpreter. This will prevent
+   finalization until the guard is closed.
+
+   For example:
+
+   .. code-block:: c
+
+      // Temporarily prevent finalization.
+      PyInterpreterGuard *guard = PyInterpreterGuard_FromCurrent();
+      if (guard == NULL) {
+         // Finalization has already started or we're out of memory.
+         return NULL;
+      }
+
+      Py_BEGIN_ALLOW_THREADS;
+      // Do some critical processing here. For example, we can safely acquire
+      // locks that might be acquired by the finalization thread.
+      Py_END_ALLOW_THREADS;
+
+      // Now that we're done with our critical processing, the interpreter is
+      // allowed to finalize again.
+      PyInterpreterGuard_Close(guard);
+
+   On success, this function returns a guard for the current interpreter;
+   on failure, it returns ``NULL`` with an exception set.
+
+   This function will fail only if the current interpreter has already started
+   finalizing, or if the process is out of memory.
+
+   The guard pointer returned by this function must be eventually closed
+   with :c:func:`PyInterpreterGuard_Close`; failing to do so will result in
+   the Python process infinitely hanging.
+
+   The caller must hold an :term:`attached thread state`.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: PyInterpreterGuard *PyInterpreterGuard_FromView(PyInterpreterView *view)
+
+   Create a finalization guard for an interpreter through a view.
+
+   On success, this function returns a guard to the interpreter
+   represented by *view*. The view is still valid after calling this
+   function. The guard must eventually be closed with
+   :c:func:`PyInterpreterGuard_Close`.
+
+   If the interpreter no longer exists, is already finalizing, or out of memory,
+   then this function returns ``NULL`` without setting an exception.
+
+   The caller does not need to hold an :term:`attached thread state`.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: void PyInterpreterGuard_Close(PyInterpreterGuard *guard)
+
+   Close an interpreter guard, allowing the interpreter to start
+   finalization if no other guards remain. If an interpreter guard
+   is never closed, the interpreter will infinitely wait when trying
+   to enter finalization!
+
+   After an interpreter guard is closed, it may not be used in
+   :c:func:`PyThreadState_Ensure`. Doing so will result in undefined
+   behavior.
+
+   This function cannot fail, and the caller doesn't need to hold an
+   :term:`attached thread state`.
+
+   .. versionadded:: 3.15
+
+
+.. _interpreter-views:
+
+Interpreter views
+-----------------
+
+In some cases, it may be necessary to access an interpreter that may have been
+deleted. This can be done using interpreter views.
+
+.. c:type:: PyInterpreterView
+
+   An opaque view of an interpreter.
+
+   This is a thread-safe way to access an interpreter that may have be
+   finalizing or already destroyed.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: PyInterpreterView *PyInterpreterView_FromCurrent(void)
+
+   Create a view to the current interpreter.
+
+   This function is generally meant to be used alongside
+   :c:func:`PyInterpreterGuard_FromView` or :c:func:`PyThreadState_EnsureFromView`.
+
+   On success, this function returns a view to the current interpreter; on
+   failure, it returns ``NULL`` with an exception set.
+
+   The caller must hold an :term:`attached thread state`.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: void PyInterpreterView_Close(PyInterpreterView *view)
+
+   Close an interpreter view.
+
+   If an interpreter view is never closed, the view's memory will never be
+   freed, but there are no other consequences. (In contrast, forgetting to

+
+   The first word (up to the first space character) is the current Python version;

+
+   Set :data:`sys.argv` based on *argc* and *argv*.  These parameters are
+   similar to those passed to the program's :c:func:`main` function with the
+   difference that the first entry should refer to the script file to be
+   executed rather than the executable hosting the Python interpreter.  If there
+   isn't a script that will be run, the first entry in *argv* can be an empty
+   string.  If this function fails to initialize :data:`sys.argv`, a fatal
+   condition is signalled using :c:func:`Py_FatalError`.
+
+   If *updatepath* is zero, this is all the function does.  If *updatepath*
+   is non-zero, the function also modifies :data:`sys.path` according to the
+   following algorithm:
+
+   - If the name of an existing script is passed in ``argv[0]``, the absolute
+     path of the directory where the script is located is prepended to
+     :data:`sys.path`.
+   - Otherwise (that is, if *argc* is ``0`` or ``argv[0]`` doesn't point
+     to an existing file name), an empty string is prepended to
+     :data:`sys.path`, which is the same as prepending the current working
+     directory (``"."``).
+
+   Use :c:func:`Py_DecodeLocale` to decode a bytes string to get a
+   :c:expr:`wchar_t*` string.
+
+   See also :c:member:`PyConfig.orig_argv` and :c:member:`PyConfig.argv`
+   members of the :ref:`Python Initialization Configuration <init-config>`.
+
+   .. note::
+      It is recommended that applications embedding the Python interpreter
+      for purposes other than executing a single script pass ``0`` as *updatepath*,
+      and update :data:`sys.path` themselves if desired.
+      See :cve:`2008-5983`.
+
+      On versions before 3.1.3, you can achieve the same effect by manually
+      popping the first :data:`sys.path` element after having called
+      :c:func:`PySys_SetArgv`, for example using::

+   If Python is :ref:`built in debug mode <debug-build>` (if the :c:macro:`Py_DEBUG`
+   macro is defined), the :c:macro:`Py_ALWAYS_INLINE` macro does nothing.
+
+   It must be specified before the function return type. Usage::
+
+       static inline Py_ALWAYS_INLINE int random(void) { return 4; }
+
+   .. versionadded:: 3.11
+
+.. c:macro:: Py_NO_INLINE
+
+   Disable inlining on a function. For example, it reduces the C stack
+   consumption: useful on LTO+PGO builds which heavily inline code (see
+   :issue:`33720`).
+
+   Corresponds to the ``noinline`` attribute/specification on GCC and MSVC.
+
+   Usage::
+
+       Py_NO_INLINE static int random(void) { return 4; }
+
+   .. versionadded:: 3.11
+
+.. c:macro:: Py_DEPRECATED(version)
+
+   Use this to declare APIs that were deprecated in a specific CPython version.
+   The macro must be placed before the symbol name.
 
    Example::
 
-      static PyMethodDef pysqlite_row_methods[] = {
-          {"keys", (PyCFunction)pysqlite_row_keys, METH_NOARGS,
-              PyDoc_STR("Returns the keys of the row.")},
-          {NULL, NULL}
-      };
+      Py_DEPRECATED(3.8) PyAPI_FUNC(int) Py_OldFunction(void);
 
-.. c:macro:: PyDoc_VAR(name)
+   .. versionchanged:: 3.8
+      MSVC support was added.
 
-   Declares a static character array variable with the given name *name*.
+.. c:macro:: Py_LOCAL(type)
 
-   For example::
+   Declare a function returning the specified *type* using a fast-calling
+   qualifier for functions that are local to the current file.
+   Semantically, this is equivalent to :samp:`static {type}`.
+
+.. c:macro:: Py_LOCAL_INLINE(type)
+
+   Equivalent to :c:macro:`Py_LOCAL` but additionally requests the function
+   be inlined.
+
+.. c:macro:: Py_LOCAL_SYMBOL
+
+   Macro used to declare a symbol as local to the shared library (hidden).
+   On supported platforms, it ensures the symbol is not exported.
+
+   On compatible versions of GCC/Clang, it
+   expands to ``__attribute__((visibility("hidden")))``.
+
+.. c:macro:: Py_EXPORTED_SYMBOL
+
+   Macro used to declare a symbol (function or data) as exported.
+   On Windows, this expands to ``__declspec(dllexport)``.
+   On compatible versions of GCC/Clang, it
+   expands to ``__attribute__((visibility("default")))``.
+   This macro is for defining the C API itself; extension modules should not use it.
+
+
+.. c:macro:: Py_IMPORTED_SYMBOL
+
+   Macro used to declare a symbol as imported.
+   On Windows, this expands to ``__declspec(dllimport)``.
+   This macro is for defining the C API itself; extension modules should not use it.
+
+
+.. c:macro:: PyAPI_FUNC(type)
+
+   Macro used by CPython to declare a function as part of the C API.
+   Its expansion depends on the platform and build configuration.
+   This macro is intended for defining CPython's C API itself;
+   extension modules should not use it for their own symbols.
+
+
+.. c:macro:: PyAPI_DATA(type)
+
+   Macro used by CPython to declare a public global variable as part of the C API.
+   Its expansion depends on the platform and build configuration.
+   This macro is intended for defining CPython's C API itself;
+   extension modules should not use it for their own symbols.

+have been standardized in C11 (or previous standards).
+
+.. c:macro:: Py_ALIGNED(num)
+
+   On some GCC-like compilers, specify alignment to *num* bytes.
+   This does nothing on other compilers.
+
+   Use the standard ``alignas`` specifier rather than this macro.

+
+   .. soft-deprecated:: 3.15
+
+.. c:macro:: Py_LL(number)
+             Py_ULL(number)
+
+   Use *number* as a ``long long`` or ``unsigned long long`` integer literal,
+   respectively.
+
+   Expands to *number* followed by ``LL`` or ``LLU``, respectively, but will
+   expand to some compiler-specific suffixes on some older compilers.
+
+   Consider using the C99 standard suffixes ``LL`` and ``LLU`` directly.

+See :ref:`capi-slots` for more information on slots in general.
 
-Modules defined using the C API typically use a *module definition*,
-:c:type:`PyModuleDef` -- a statically allocated, constant “description" of
-how a module should be created.
+.. versionchanged:: 3.15
 
-The definition is usually used to define an extension's “main” module object
-(see :ref:`extension-modules` for details).
-It is also used to
-:ref:`create extension modules dynamically <moduledef-dynamic>`.
+   Previously, a :c:type:`PyModuleDef` struct was necessary to define modules.
+   The older way of defining modules is still available: consult either the
+   :ref:`pymoduledef` section or earlier versions of this documentation
+   if you plan to support earlier Python versions.
 
-Unlike :c:func:`PyModule_New`, the definition allows management of
-*module state* -- a piece of memory that is allocated and cleared together
-with the module object.
-Unlike the module's Python attributes, Python code cannot replace or delete
-data stored in module state.

-      Name for the new module.
+   Note that modules are typically created using a
+   :py:class:`~importlib.machinery.ModuleSpec`, and when they are, the

+Module state
+------------
 
-   .. versionadded:: 3.12
+Extension modules can have *module state* -- a
+piece of memory that is allocated on module creation,
+and freed when the module object is deallocated.
+The module state is specified using :ref:`dedicated slots <ext-module-state-slots>`.
 
-.. c:macro:: Py_mod_gil
+A typical use of module state is storing an exception type -- or indeed *any*
+type object defined by the module --
 
-   Specifies one of the following values:
+Unlike the module's Python attributes, Python code cannot replace or delete
+data stored in module state.
 
-   .. c:namespace:: NULL
+Keeping per-module information in attributes and module state, rather than in
+static globals, makes module objects *isolated* and safer for use in
+multiple sub-interpreters.
+It also helps Python do an orderly clean-up when it shuts down.
 
-   .. c:macro:: Py_MOD_GIL_USED
+Extensions that keep references to Python objects as part of module state must
+implement :c:macro:`Py_mod_state_traverse` and :c:macro:`Py_mod_state_clear`
+functions to avoid reference leaks.
 
-      The module depends on the presence of the global interpreter lock (GIL),
-      and may access global state without synchronization.
+To retrieve the state from a given module, use the following functions:
 
-   .. c:macro:: Py_MOD_GIL_NOT_USED
+.. c:function:: void* PyModule_GetState(PyObject *module)
 
-      The module is safe to run without an active GIL.
+   Return the "state" of the module, that is, a pointer to the block of memory
+   allocated at module creation time, or ``NULL``.  See
+   :c:macro:`Py_mod_state_size`.
 
-   This slot is ignored by Python builds not configured with
-   :option:`--disable-gil`.  Otherwise, it determines whether or not importing
-   this module will cause the GIL to be automatically enabled. See
-   :ref:`whatsnew313-free-threaded-cpython` for more detail.
+   On error, return ``NULL`` with an exception set.
+   Use :c:func:`PyErr_Occurred` to tell this case apart from missing
+   module state.
 
-   Multiple ``Py_mod_gil`` slots may not be specified in one module definition.
 
-   If ``Py_mod_gil`` is not specified, the import machinery defaults to
-   ``Py_MOD_GIL_USED``.
+.. c:function:: int PyModule_GetStateSize(PyObject *module, Py_ssize_t *result)
 
-   .. versionadded:: 3.13
+   Set *\*result* to the size of *module*'s state, as specified
+   using :c:macro:`Py_mod_state_size` (or :c:member:`PyModuleDef.m_size`),
+   and return 0.
 
-.. c:macro:: Py_mod_abi
+   On error, set *\*result* to -1, and return -1 with an exception set.
 
-   A pointer to a :c:struct:`PyABIInfo` structure that describes the ABI that
-   the extension is using.
+   .. versionadded:: 3.15
 
-   When the module is loaded, the :c:struct:`!PyABIInfo` in this slot is checked
-   using :c:func:`PyABIInfo_Check`.
 
-   A suitable :c:struct:`!PyABIInfo` variable can be defined using the
-   :c:macro:`PyABIInfo_VAR` macro, as in:

-      static PyModuleDef_Slot mymodule_slots[] = {

+The following :c:member:`slot IDs <PySlot.sl_id>`  are available for
+defining the module state.
+
+.. c:macro:: Py_mod_state_size
+
+   :c:member:`Slot ID <PySlot.sl_id>` for the size of the module state,
+   in bytes.
+
+   Setting the value to a non-negative value means that the module can be
+   re-initialized and specifies the additional amount of memory it requires
+   for its state.
+
+   See :PEP:`3121` for more details.
+
+   Use :c:func:`PyModule_GetStateSize` to retrieve the size of a given module.

+
+   .. c:function:: int traverse_module_state(PyObject *module, visitproc visit, void *arg)
+      :no-index-entry:
+      :no-contents-entry:
+
+   This function is not called if the module state was requested but is not
+   allocated yet. This is the case immediately after the module is created
+   and before the module is executed (:c:data:`Py_mod_exec` function). More
+   precisely, this function is not called if the state size
+   (:c:data:`Py_mod_state_size`) is greater than 0 and the module state
+   (as returned by :c:func:`PyModule_GetState`) is ``NULL``.

+
+   The signature of the function is:
+
+   .. c:function:: int clear_module_state(PyObject* module)
+      :no-index-entry:
+      :no-contents-entry:
+
+   This function is not called if the module state was requested but is not

+   (:c:data:`Py_mod_state_size`) is greater than 0 and the module state
+   (as returned by :c:func:`PyModule_GetState`) is ``NULL``.
+
+   Like :c:member:`PyTypeObject.tp_clear`, this function is not *always*
+   called before a module is deallocated. For example, when reference
+   counting is enough to determine that an object is no longer used,
+   the cyclic garbage collector is not involved and
+   the :c:macro:`Py_mod_state_free` function is called directly.
+
+   .. versionadded:: 3.15
+
+      Use :c:member:`PyModuleDef.m_clear` instead to support previous versions.
+
+.. c:macro:: Py_mod_state_free
+
+   :c:member:`Slot ID <PySlot.sl_id>` for a function to call during
+   deallocation of the module object.
+
+   The signature of the function is:
+
+   .. c:function:: int free_module_state(PyObject* module)
+      :no-index-entry:
+      :no-contents-entry:
+
+   This function is not called if the module state was requested but is not

+
+
+.. _ext-module-token:
+
+Module token
+............
+
+Each module may have an associated *token*: a pointer-sized value intended to
+identify of the module state's memory layout.
+This means that if you have a module object, but you are not sure if it
+“belongs” to your extension, you can check using code like this:
+
+.. code-block:: c
+
+   PyObject *module = <the module in question>
+
+   void *module_token;
+   if (PyModule_GetToken(module, &module_token) < 0) {
+       return NULL;
+   }
+   if (module_token != your_token) {
+       PyErr_SetString(PyExc_ValueError, "unexpected module")
+       return NULL;
+   }
+
+   // This module's state has the expected memory layout; it's safe to cast
+   struct my_state state = (struct my_state*)PyModule_GetState(module)
+
+A module's token -- and the *your_token* value to use in the above code -- is:
+
+- For modules created with :c:type:`PyModuleDef`: the address of that
+  :c:type:`PyModuleDef`;
+- For modules defined with the :c:macro:`Py_mod_token` slot: the value
+  of that slot;
+- For modules created from an ``PyModExport_*``
+  :ref:`export hook <extension-export-hook>`: the slots array that the export
+  hook returned (unless overridden with :c:macro:`Py_mod_token`).
+
+.. c:macro:: Py_mod_token
+
+   :c:member:`Slot ID <PySlot.sl_id>` for the module token.
+
+   If you use this slot to set the module token (rather than rely on the
+   default), you must ensure that:
+
+   * The pointer outlives the class, so it's not reused for something else
+     while the class exists.
+   * It "belongs" to the extension module where the class lives, so it will not
+     clash with other extensions.
+   * If the token points to a :c:type:`PyModuleDef` struct, the module should
+     behave as if it was created from that :c:type:`PyModuleDef`.
+     In particular, the module state must have matching layout and semantics.
+
+   Modules created from :c:type:`PyModuleDef` always use the address of
+   the :c:type:`PyModuleDef` as the token.
+   This means that :c:macro:`!Py_mod_token` cannot be used in
+   :c:member:`PyModuleDef.m_slots`.
+
+   .. versionadded:: 3.15
+
+.. c:function:: int PyModule_GetToken(PyObject *module, void** result)

+
+.. c:function:: PyObject *PyModule_FromSlotsAndSpec(const PySlot *slots, PyObject *spec)
+
+   Create a new module object, given an array of :ref:`slots <pymoduledef_slot>`
+   and the :py:class:`~importlib.machinery.ModuleSpec` *spec*.
+
+   The *slots* argument must point to an array of :c:type:`PySlot`
+   structures, terminated by an entry with slot ID of 0
+   (typically written as :c:macro:`PySlot_END`).
+   The array must include a :c:data:`Py_mod_abi` entry.
+
+   The *spec* argument may be any ``ModuleSpec``-like object, as described
+   in :c:macro:`Py_mod_create` documentation.
+   Currently, the *spec* must have a ``name`` attribute.
+
+   On success, return the new module.
+   On error, return ``NULL`` with an exception set.
+
+   Note that this does not process the module's execution slot
+   (:c:data:`Py_mod_exec`).
+   Both :c:func:`!PyModule_FromSlotsAndSpec` and :c:func:`PyModule_Exec`

+.. _pymoduledef:
+
+Module definition struct
+------------------------
+
+Traditionally, extension modules were defined using a *module definition*
+as the “description" of how a module should be created.
+Rather than using an array of :ref:`slots <pymoduledef_slot>` directly,
+the definition has dedicated members for most common functionality,
+and allows additional slots as an extension mechanism.
+
+This way of defining modules is still available and there are no plans to
+remove it.
+
+.. c:type:: PyModuleDef
+
+   The module definition struct, which holds information needed to create
+   a module object.
+
+   This structure must be statically allocated (or be otherwise guaranteed
+   to be valid while any modules created from it exist).
+   Usually, there is only one variable of this type for each extension module
+   defined this way.
+
+   The struct, including all members, is part of the
+   :ref:`Stable ABI <stable-abi>` for non-free-threaded builds (``abi3``).
+   In the Stable ABI for free-threaded builds (``abi3t``),
+   this struct is opaque, and unusable in practice; see :ref:`pymoduledef_slot`
+   for a replacement.
+
+   .. c:member:: PyModuleDef_Base m_base
+
+      Always initialize this member to :c:macro:`PyModuleDef_HEAD_INIT`:
+
+      .. c:namespace:: NULL
+
+      .. c:type:: PyModuleDef_Base
+
+         The type of :c:member:`!PyModuleDef.m_base`.
+
+         The struct is part of the :ref:`Stable ABI <stable-abi>` for
+         non-free-threaded builds (``abi3``).
+         In the Stable ABI for Free-Threaded Builds
+         (``abi3t``), this struct is opaque, and unusable in practice.
+
+      .. c:macro:: PyModuleDef_HEAD_INIT
+
+         The required initial value for :c:member:`!PyModuleDef.m_base`.
+
+   .. c:member:: const char *m_name
+
+      Corresponds to the :c:macro:`Py_mod_name` slot.
+
+   .. c:member:: const char *m_doc
+
+      These members correspond to the :c:macro:`Py_mod_doc` slot.
+      Setting this to NULL is equivalent to omitting the slot.
+
+   .. c:member:: Py_ssize_t m_size
+
+      Corresponds to the :c:macro:`Py_mod_state_size` slot.
+      Setting this to zero is equivalent to omitting the slot.
+
+      When using :ref:`legacy single-phase initialization <single-phase-initialization>`
+      or when creating modules dynamically using :c:func:`PyModule_Create`
+      or :c:func:`PyModule_Create2`, :c:member:`!m_size` may be set to -1.
+      This indicates that the module does not support sub-interpreters,
+      because it has global state.
+
+   .. c:member:: PyMethodDef *m_methods
+
+      Corresponds to the :c:macro:`Py_mod_methods` slot.
+      Setting this to NULL is equivalent to omitting the slot.
+
+   .. c:member:: PyModuleDef_Slot* m_slots
+
+      An array of additional slots, terminated by a ``{0, NULL}`` entry.
+      Note that the entries use the older :c:type:`PyModuleDef_Slot` structure,
+      rather than :c:type:`PySlot`.
+
+      If the array contains slots corresponding to :c:type:`PyModuleDef`
+      members, the values must match.
+      For example, if you use :c:macro:`Py_mod_name` in :c:member:`!m_slots`,
+      :c:member:`PyModuleDef.m_name` must be set to the same pointer
+      (not just an equal string).
+
+      .. versionchanged:: 3.5
+
+         Prior to version 3.5, this member was always set to ``NULL``,
+         and was defined as:
+
+           .. c:member:: inquiry m_reload
+
+      .. c:namespace:: NULL
+
+      .. c:type:: PyModuleDef_Slot
+
+         Older structure defining additional slots of a module.
+
+         Note that a :c:type:`!PyModuleDef_Slot` array may be included in a
+         :c:type:`!PySlot` array using :c:macro:`Py_mod_slots`,
+         and vice versa using :c:macro:`Py_slot_subslots`.
+
+         Each :c:type:`!PyModuleDef_Slot` structure ``modslot`` is interpreted
+         as the following :c:type:`PySlot` structure::
+
+            (PySlot){
+               .sl_id=modslot.slot,
+               .sl_flags=PySlot_INTPTR | sub_static,
+               .sl_ptr=modslot.value
+            }
+
+         where ``sub_static`` is ``PySlot_STATIC`` if the slot requires
+         the flag (such as for :c:macro:`Py_mod_methods`), or if this flag
+         is present on the "parent" :c:macro:`!Py_mod_slots` slot (if any).
+
+         .. c:member:: int slot
+
+            Corresponds to :c:member:`PySlot.sl_id`.
+
+         .. c:member:: void* value

+=====================

+
+This C interface allows the profiling or tracing code to avoid the overhead of
+calling through Python-level callable objects, making a direct C function call
+instead.  The essential attributes of the facility have not changed; the

+   exception has been raised.  The callback function is called with this value for
+   *what* when after any bytecode is processed after which the exception becomes
+   set within the frame being executed.  The effect of this is that as exception

+Definition slots
+================
+
+To define :ref:`module objects <moduleobjects>` and
+:ref:`classes <creating-heap-types>` using the C API, you may use
+an array of *slots* -- essentially, key-value pairs that describe features
+of the object to create.
+This decouples the data from the structures used at runtime, allowing CPython
+-- and other Python C API implementations -- to update the structures without
+breaking backwards compatibility.
+
+This section documents slots in general.
+For object-specific behavior and slot values, see documentation for functions
+that apply slots:
+
+- :c:func:`PyType_FromSlots` for types;
+- :c:func:`PyModule_FromSlotsAndSpec` and :ref:`extension-export-hook`
+  for modules.
+
+When slots are passed to a function that applies them, the function will
+not modify the slot array, nor any data it points to (recursively).
+After the function is done, the caller is allowed to modify or deallocate
+the array and any data it points to (recursively), except data
+explicitly marked with :c:macro:`PySlot_STATIC`.
+
+Except when documented otherwise, multiple slots with the same ID
+(:c:member:`~PySlot.sl_id`) may not occur in a single slots array.
+
+.. versionadded:: 3.15
+
+   Slot arrays generalize an earlier way of defining objects:
+   using :c:type:`PyType_Spec` with :c:type:`PyType_Slot` for types, and
+   :c:type:`PyModuleDef` with :c:type:`PyModuleDef_Slot` for modules.
+   The earlier API is :term:`soft deprecated`; there are no plans to remove it.
+
+Entries of the slots array use the following structure:
+
+.. c:type:: PySlot
+
+   An entry in a slots array. Defined as:
+
+   .. code-block:: c
+
+    typedef struct {
+        uint16_t sl_id;
+        uint16_t sl_flags;
+        uint32_t _reserved;  // must be 0
+        union {
+            void *sl_ptr;
+            void (*sl_func)(void);
+            Py_ssize_t sl_size;
+            int64_t sl_int64;
+            uint64_t sl_uint64;
+        };
+    } PySlot;
+
+   .. c:member:: uint16_t sl_id
+
+      A slot ID, chosen from:
+
+      - ``Py_slot_*`` values documented in :ref:`pyslot-common-ids` below;
+      - ``Py_mod_*`` values for modules, as documented in :ref:`c_module_slots`;
+      - Values for types, as documented in :ref:`pyslot_type_slot_ids`.
+
+      A :c:member:`!sl_id` of zero (:c:macro:`Py_slot_end`) marks the end of a
+      slots array.
+
+   .. c:member:: void *sl_ptr
+                 void (*sl_func)(void)
+                 Py_ssize_t sl_size
+                 int64_t sl_int64
+                 uint64_t sl_uint64
+
+      The data for the slot.
+      These members are part of an anonymous union;
+      the member to use depends on which data type is required by the slot ID:
+      data pointer, function pointer, size, signed or unsigned
+      integer, respectively.
+
+      Except when documented otherwise for a specific slot ID, pointers
+      (that is :c:member:`!sl_ptr` and :c:member:`!sl_func`) may not be NULL.
+
+   .. c:member:: uint16_t sl_flags
+
+      Zero or more of the following flags, OR-ed together:
+
+      .. c:namespace:: NULL
+
+      .. c:macro:: PySlot_STATIC
+
+         All data the slot points to is statically allocated and constant.
+         Thus, the interpreter does not need to copy the information.
+
+         This flag is implied for function pointers.
+
+         The flag applies even to data the slot points to “indirectly”,
+         except for slots nested via :c:macro:`Py_slot_subslots` which may
+         have their own :c:macro:`!PySlot_STATIC` flags.
+         For example, if applied to a :c:macro:`Py_tp_members` slot that
+         points to an array of :c:type:`PyMemberDef` structures,
+         then the entire array, as well as the name and doc strings
+         in its elements, must be static and constant.
+
+      .. c:macro:: PySlot_INTPTR
+
+         The data is stored in ``sl_ptr``; CPython will cast it to
+         the appropriate type.
+
+         This flag can simplify porting from the older :c:type:`PyType_Slot`
+         and :c:type:`PyModuleDef_Slot` structures.
+
+      .. c:macro:: PySlot_OPTIONAL
+
+         If the slot ID is unknown, the interpreter should ignore the
+         slot, rather than fail.
+
+         For example, if Python 3.16 adds a new feature with a new slot ID,attr
+         the corresponding slot may be marked :c:macro:`!PySlot_OPTIONAL`
+         so that Python 3.15 ignores it.
+
+         Note that the "optionality" only applies to unknown slot IDs.
+         This flag does not make Python skip invalid values of known slots.
+
+   .. versionadded:: 3.15

+
+Convenience macros

+
+.. c:macro:: PySlot_DATA(name, value)

-Limited C API
--------------
+   For simplicity, this document talks about *extensions*, but Stable ABI
+   works the same way for all uses of the API – for example, embedding Python.
 
-Python 3.2 introduced the *Limited API*, a subset of Python's C API.
-Extensions that only use the Limited API can be
-compiled once and be loaded on multiple versions of Python.
-Contents of the Limited API are :ref:`listed below <limited-api-list>`.
+There are two Stable ABIs:
 
-.. c:macro:: Py_LIMITED_API
+- ``abi3``, introduced in Python 3.2, is compatible with
+  **non**-:term:`free-threaded <free-threaded build>` builds of CPython.
 
-   Define this macro before including ``Python.h`` to opt in to only use
-   the Limited API, and to select the Limited API version.
+- ``abi3t``, introduced in Python 3.15, is compatible with
+  :term:`free-threaded <free-threaded build>` builds of CPython.
+  It has stricter API limitations than ``abi3``.
 
-   Define ``Py_LIMITED_API`` to the value of :c:macro:`PY_VERSION_HEX`
-   corresponding to the lowest Python version your extension supports.
-   The extension will be ABI-compatible with all Python 3 releases
-   from the specified one onward, and can use Limited API introduced up to that
-   version.
+   .. versionadded:: 3.15
 
-   Rather than using the ``PY_VERSION_HEX`` macro directly, hardcode a minimum
-   minor version (e.g. ``0x030A0000`` for Python 3.10) for stability when
-   compiling with future Python versions.
+      ``abi3t`` was added in :pep:`803`
 
-   You can also define ``Py_LIMITED_API`` to ``3``. This works the same as
-   ``0x03020000`` (Python 3.2, the version that introduced Limited API).
+It is possible for an extension to be compiled for *both* ``abi3`` and
+``abi3t`` at the same time; the result will be compatible with
+both free-threaded and non-free-threaded builds of Python.
+Currently, this has no downsides compared to compiling for ``abi3t`` only.
 
+Each Stable ABI is versioned using the first two numbers of the Python version.
+For example, Stable ABI 3.14 corresponds to Python 3.14.
+An extension compiled for Stable ABI 3.x is ABI-compatible with Python 3.x
+and above.
 
-.. _stable-abi:
+Extensions that target a stable ABI must only use a limited subset of
+the C API. This subset is known as the :dfn:`Limited API`; its contents
+are :ref:`listed below <limited-api-list>`.
 
-Stable ABI
-----------
+On Windows, extensions that use a Stable ABI should be linked against
+``python3.dll`` rather than a version-specific library such as
+``python39.dll``.
+This library only exposes the relevant symbols.
+
+On some platforms, Python will look for and load shared library files named
+with the ``abi3`` or ``abi3t`` tag (for example, ``mymodule.abi3.so``).
+:term:`Free-threaded <free-threaded build>` interpreters only recognize the
+``abi3t`` tag, while non-free-threaded ones will prefer ``abi3`` but fall back
+to ``abi3t``.
+Thus, extensions compatible with both ABIs should use the ``abi3t`` tag.
+
+Python does not necessarily check that extensions it loads
+have compatible ABI.
+Extension authors are encouraged to add a check using the :c:macro:`Py_mod_abi`
+slot or the :c:func:`PyABIInfo_Check` function, but the user
+(or their packaging tool) is ultimately responsible for ensuring that,
+for example, extensions built for Stable ABI 3.10 are not installed for lower
+versions of Python.
 
-To enable this, Python provides a *Stable ABI*: a set of symbols that will
-remain ABI-compatible across Python 3.x versions.
+All functions in Stable ABI are present as functions in Python's shared
+library, not solely as macros.
+This makes them usable in languages that don't use the C
+preprocessor, including Python's :py:mod:`ctypes`.
+
+
+.. _abi3-compiling:
+
+Compiling for Stable ABI
+------------------------
 
 .. note::
 
-   The Stable ABI prevents ABI issues, like linker errors due to missing
-   symbols or data corruption due to changes in structure layouts or function
-   signatures.
-   However, other changes in Python can change the *behavior* of extensions.
-   See Python's Backwards Compatibility Policy (:pep:`387`) for details.
+   Build tools (such as, for example, meson-python, scikit-build-core,
+   or Setuptools) often have a mechanism for setting macros and synchronizing
+   them with extension filenames and other metadata.
+   Prefer using such a mechanism, if it exists, over defining the
+   macros manually.
 
-The Stable ABI contains symbols exposed in the :ref:`Limited API
-<limited-c-api>`, but also other ones – for example, functions necessary to
-support older versions of the Limited API.
+   The rest of this section is mainly relevant for tool authors, and for
+   people who compile extensions manually.
 
-On Windows, extensions that use the Stable ABI should be linked against
-``python3.dll`` rather than a version-specific library such as
-``python39.dll``.
+   .. seealso:: `list of recommended tools`_ in the Python Packaging User Guide
 
-On some platforms, Python will look for and load shared library files named
-with the ``abi3`` tag (e.g. ``mymodule.abi3.so``).
-It does not check if such extensions conform to a Stable ABI.
-The user (or their packaging tools) need to ensure that, for example,
-extensions built with the 3.10+ Limited API are not installed for lower
-versions of Python.
+      .. _list of recommended tools: https://packaging.python.org/en/latest/guides/tool-recommendations/#build-backends-for-extension-modules
+
+To compile for a Stable ABI, define one or both of the following macros
+to the lowest Python version your extension should support, in
+:c:macro:`Py_PACK_VERSION` format.
+Typically, you should choose a specific value rather than the version of
+the Python headers you are compiling against.
+
+The macros must be defined before including ``Python.h``.
+Since :c:macro:`Py_PACK_VERSION` is not available at this point, you
+will need to use the numeric value directly.
+For reference, the values for a few recent Python versions are:
+
+.. version-hex-cheatsheet::
 
-All functions in the Stable ABI are present as functions in Python's shared
-library, not solely as macros. This makes them usable from languages that don't
-use the C preprocessor.
+When one of the macros is defined, ``Python.h`` will only expose API that is
+compatible with the given Stable ABI -- that is, the
+:ref:`Limited API <limited-api-list>` plus some definitions that need to be
+visible to the compiler but should not be used directly.

+Stable ABI Scope and Performance
+--------------------------------

+The goal for Stable ABI is to allow everything that is possible with the
 full C API, but possibly with a performance penalty.

+extension's source code.

 The macro can be faster because it can rely on version-specific implementation

-Limited API Caveats

+Stable ABI Caveats
+------------------
 
-Note that compiling with ``Py_LIMITED_API`` is *not* a complete guarantee that
-code conforms to the :ref:`Limited API <limited-c-api>` or the :ref:`Stable ABI
-<stable-abi>`. ``Py_LIMITED_API`` only covers definitions, but an API also
-includes other issues, such as expected semantics.
+Note that compiling for Stable ABI is *not* a complete guarantee that code will
+be compatible with the expected Python versions.
+Stable ABI prevents *ABI* issues, like linker errors due to missing
+symbols or data corruption due to changes in structure layouts or function
+signatures.
+However, other changes in Python can change the *behavior* of extensions.
 
-One issue that ``Py_LIMITED_API`` does not guard against is calling a function
-with arguments that are invalid in a lower Python version.
+One issue that the :c:macro:`Py_TARGET_ABI3T` and :c:macro:`Py_LIMITED_API`
+macros do not guard against is calling a function with arguments that are
+invalid in a lower Python version.
 For example, consider a function that starts accepting ``NULL`` for an
 argument. In Python 3.9, ``NULL`` now selects a default behavior, but in
 Python 3.8, the argument will be used directly, causing a ``NULL`` dereference
 and crash. A similar argument works for fields of structs.
 
-Another issue is that some struct fields are currently not hidden when
-``Py_LIMITED_API`` is defined, even though they're part of the Limited API.
-
 For these reasons, we recommend testing an extension with *all* minor Python
-versions it supports, and preferably to build with the *lowest* such version.
+versions it supports.
 
 We also recommend reviewing documentation of all used API to check
 if it is explicitly part of the Limited API. Even with ``Py_LIMITED_API``
 defined, a few private declarations are exposed for technical reasons (or
 even unintentionally, as bugs).
 
-Also note that the Limited API is not necessarily stable: compiling with
-``Py_LIMITED_API`` with Python 3.8 means that the extension will
-run with Python 3.12, but it will not necessarily *compile* with Python 3.12.
-In particular, parts of the Limited API may be deprecated and removed,
-provided that the Stable ABI stays stable.
+Also note that while compiling with ``Py_LIMITED_API`` 3.8 means that the
+extension should *load* on Python 3.12, and *compile* with Python 3.12,
+the same source will not necessarily compile with ``Py_LIMITED_API``
+set to 3.12.
+In general, parts of the Limited API may be deprecated and removed,
+provided that Stable ABI stays stable.

+Multiple interpreters in a Python process
+=========================================
+
+While in most uses, you will only embed a single Python interpreter, there
+are cases where you need to create several independent interpreters in the
+same process and perhaps even in the same thread. Sub-interpreters allow
+you to do that.
+
+The "main" interpreter is the first one created when the runtime initializes.
+It is usually the only Python interpreter in a process.  Unlike sub-interpreters,
+the main interpreter has unique process-global responsibilities like signal
+handling.  It is also responsible for execution during runtime initialization and
+is usually the active interpreter during runtime finalization.  The
+:c:func:`PyInterpreterState_Main` function returns a pointer to its state.
+
+You can switch between sub-interpreters using the :c:func:`PyThreadState_Swap`
+function. You can create and destroy them using the following functions:
+
+
+.. c:type:: PyInterpreterConfig
+
+   Structure containing most parameters to configure a sub-interpreter.
+   Its values are used only in :c:func:`Py_NewInterpreterFromConfig` and

+   Structure fields:

+   .. c:member:: int use_main_obmalloc
+
+      If this is ``0`` then the sub-interpreter will use its own
+      "object" allocator state.
+      Otherwise it will use (share) the main interpreter's.
+
+      If this is ``0`` then
+      :c:member:`~PyInterpreterConfig.check_multi_interp_extensions`
+      must be ``1`` (non-zero).

+      process in any thread where the sub-interpreter is currently active.
+      Otherwise fork is unrestricted.
+
+      Note that the :mod:`subprocess` module still works
+      when fork is disallowed.

+   .. c:member:: int allow_exec
+
+      If this is ``0`` then the runtime will not support replacing the
+      current process via exec (e.g. :func:`os.execv`) in any thread
+      where the sub-interpreter is currently active.
+      Otherwise exec is unrestricted.
+
+      Note that the :mod:`subprocess` module still works
+      when exec is disallowed.
+
+   .. c:member:: int allow_threads
+
+      If this is ``0`` then the sub-interpreter's :mod:`threading` module
+      won't create threads.
+      Otherwise threads are allowed.
+
+   .. c:member:: int allow_daemon_threads
+
+      If this is ``0`` then the sub-interpreter's :mod:`threading` module
+      won't create daemon threads.

+      :c:member:`~PyInterpreterConfig.allow_threads` is non-zero).

+      Otherwise only multi-phase init extension modules
+      (see :pep:`489`) may be imported.
+      (Also see :c:macro:`Py_mod_multiple_interpreters`.)
+
+      This must be ``1`` (non-zero) if
+      :c:member:`~PyInterpreterConfig.use_main_obmalloc` is ``0``.
+
+   .. c:member:: int gil
+
+      This determines the operation of the GIL for the sub-interpreter.

+
+         Use (share) the main interpreter's GIL.
+
+      .. c:macro:: PyInterpreterConfig_OWN_GIL
+
+         Use the sub-interpreter's own GIL.
+
+      If this is :c:macro:`PyInterpreterConfig_OWN_GIL` then
+      :c:member:`PyInterpreterConfig.use_main_obmalloc` must be ``0``.

+      }
+
+   Note that the config is used only briefly and does not get modified.
+   During initialization the config's values are converted into various
+   :c:type:`PyInterpreterState` values.  A read-only copy of the config
+   may be stored internally on the :c:type:`PyInterpreterState`.
+
+   .. index::
+      single: Py_FinalizeEx (C function)
+      single: Py_Initialize (C function)
+
+   Extension modules are shared between (sub-)interpreters as follows:
+
+   *  For modules using multi-phase initialization,
+      e.g. :c:func:`PyModule_FromDefAndSpec`, a separate module object is
+      created and initialized for each interpreter.
+      Only C-level static and global variables are shared between these
+      module objects.
+
+   *  For modules using legacy
+      :ref:`single-phase initialization <single-phase-initialization>`,
+      e.g. :c:func:`PyModule_Create`, the first time a particular extension
+      is imported, it is initialized normally, and a (shallow) copy of its
+      module's dictionary is squirreled away.
+      When the same extension is imported by another (sub-)interpreter, a new
+      module is initialized and filled with the contents of this copy; the
+      extension's ``init`` function is not called.
+      Objects in the module's dictionary thus end up shared across
+      (sub-)interpreters, which might cause unwanted behavior (see
+      `Bugs and caveats`_ below).
+
+      Note that this is different from what happens when an extension is
+      imported after the interpreter has been completely re-initialized by
+      calling :c:func:`Py_FinalizeEx` and :c:func:`Py_Initialize`; in that
+      case, the extension's ``initmodule`` function *is* called again.
+      As with multi-phase initialization, this means that only C-level static
+      and global variables are shared between these modules.
+

+      single: stdin (in module sys)
+
+   Create a new sub-interpreter.  This is essentially just a wrapper
+   around :c:func:`Py_NewInterpreterFromConfig` with a config that
+   preserves the existing behavior.  The result is an unisolated
+   sub-interpreter that shares the main interpreter's GIL, allows
+   fork/exec, allows daemon threads, and allows single-phase init
+   modules.
+
+
+.. c:function:: void Py_EndInterpreter(PyThreadState *tstate)
+

+   The given thread state must be :term:`attached <attached thread state>`.
+   When the call returns, there will be no :term:`attached thread state`.
+   All thread states associated with this interpreter are destroyed.
+
+   :c:func:`Py_FinalizeEx` will destroy all sub-interpreters that
+   haven't been explicitly destroyed at that point.
+
+
+.. _per-interpreter-gil:
+
+A per-interpreter GIL
+---------------------
+
+.. versionadded:: 3.12
+
+Using :c:func:`Py_NewInterpreterFromConfig` you can create
+a sub-interpreter that is completely isolated from other interpreters,
+including having its own GIL.  The most important benefit of this
+isolation is that such an interpreter can execute Python code without
+being blocked by other interpreters or blocking any others.  Thus a
+single Python process can truly take advantage of multiple CPU cores
+when running Python code.  The isolation also encourages a different
+approach to concurrency than that of just using threads.
+(See :pep:`554` and :pep:`684`.)
+
+Using an isolated interpreter requires vigilance in preserving that
+isolation.  That especially means not sharing any objects or mutable
+state without guarantees about thread-safety.  Even objects that are
+otherwise immutable (e.g. ``None``, ``(1, 5)``) can't normally be shared
+because of the refcount.  One simple but less-efficient approach around
+this is to use a global lock around all use of some state (or object).
+Alternately, effectively immutable objects (like integers or strings)
+can be made safe in spite of their refcounts by making them :term:`immortal`.
+In fact, this has been done for the builtin singletons, small integers,
+and a number of other builtin objects.
+
+If you preserve isolation then you will have access to proper multi-core
+computing without the complications that come with free-threading.
+Failure to preserve isolation will expose you to the full consequences
+of free-threading, including races and hard-to-debug crashes.
+
+Aside from that, one of the main challenges of using multiple isolated
+interpreters is how to communicate between them safely (not break
+isolation) and efficiently.  The runtime and stdlib do not provide
+any standard approach to this yet.  A future stdlib module would help
+mitigate the effort of preserving isolation and expose effective tools
+for communicating (and sharing) data between interpreters.
+
+
+Bugs and caveats
+----------------
+
+Because sub-interpreters (and the main interpreter) are part of the same
+process, the insulation between them isn't perfect --- for example, using
+low-level file operations like :func:`os.close` they can
+(accidentally or maliciously) affect each other's open files.  Because of the
+way extensions are shared between (sub-)interpreters, some extensions may not
+work properly; this is especially likely when using single-phase initialization
+or (static) global variables.
+It is possible to insert objects created in one sub-interpreter into
+a namespace of another (sub-)interpreter; this should be avoided if possible.
+
+Special care should be taken to avoid sharing user-defined functions,
+methods, instances or classes between sub-interpreters, since import
+operations executed by such objects may affect the wrong (sub-)interpreter's
+dictionary of loaded modules. It is equally important to avoid sharing
+objects from which the above are reachable.
+
+Also note that combining this functionality with ``PyGILState_*`` APIs
+is delicate, because these APIs assume a bijection between Python thread states
+and OS-level threads, an assumption broken by the presence of sub-interpreters.
+It is highly recommended that you don't switch sub-interpreters between a pair
+of matching :c:func:`PyGILState_Ensure` and :c:func:`PyGILState_Release` calls.
+Furthermore, extensions (such as :mod:`ctypes`) using these APIs to allow calling
+of Python code from non-Python created threads will probably be broken when using
+sub-interpreters.
+
+
+High-level APIs
+---------------
+
+.. c:type:: PyInterpreterState
+
+   This data structure represents the state shared by a number of cooperating
+   threads.  Threads belonging to the same interpreter share their module
+   administration and a few other internal items. There are no public members in
+   this structure.
+
+   Threads belonging to different interpreters initially share nothing, except
+   process state like available memory, open file descriptors and such.  The global
+   interpreter lock is also shared by all threads, regardless of to which
+   interpreter they belong.
+
+   .. versionchanged:: 3.12
+
+      :pep:`684` introduced the possibility
+      of a :ref:`per-interpreter GIL <per-interpreter-gil>`.
+      See :c:func:`Py_NewInterpreterFromConfig`.
+
+
+.. c:function:: PyInterpreterState* PyInterpreterState_Get(void)
+
+   Get the current interpreter.
+
+   Issue a fatal error if there is no :term:`attached thread state`.
+   It cannot return NULL.
+
+   .. versionadded:: 3.9
+
+
+.. c:function:: int64_t PyInterpreterState_GetID(PyInterpreterState *interp)
+
+   Return the interpreter's unique ID.  If there was any error in doing
+   so then ``-1`` is returned and an error is set.
+
+   The caller must have an :term:`attached thread state`.
+
+   .. versionadded:: 3.7
+
+
+.. c:function:: PyObject* PyInterpreterState_GetDict(PyInterpreterState *interp)
+
+   Return a dictionary in which interpreter-specific data may be stored.
+   If this function returns ``NULL`` then no exception has been raised and
+   the caller should assume no interpreter-specific dict is available.
+
+   This is not a replacement for :c:func:`PyModule_GetState()`, which
+   extensions should use to store interpreter-specific state information.
+
+   The returned dictionary is borrowed from the interpreter and is valid until
+   interpreter shutdown.
+
+   .. versionadded:: 3.8
+
+
+.. c:type:: PyObject* (*_PyFrameEvalFunction)(PyThreadState *tstate, _PyInterpreterFrame *frame, int throwflag)
+
+   Type of a frame evaluation function.
+
+   The *throwflag* parameter is used by the ``throw()`` method of generators:
+   if non-zero, handle the current exception.
+
+   .. versionchanged:: 3.9
+      The function now takes a *tstate* parameter.
+
+   .. versionchanged:: 3.11
+      The *frame* parameter changed from ``PyFrameObject*`` to ``_PyInterpreterFrame*``.
+
+
+.. c:function:: _PyFrameEvalFunction _PyInterpreterState_GetEvalFrameFunc(PyInterpreterState *interp)
+
+   Get the frame evaluation function.
+
+   See the :pep:`523` "Adding a frame evaluation API to CPython".
+
+   .. versionadded:: 3.9
+
+
+.. c:function:: void _PyInterpreterState_SetEvalFrameFunc(PyInterpreterState *interp, _PyFrameEvalFunction eval_frame)
+
+   Set the frame evaluation function.
+
+   See the :pep:`523` "Adding a frame evaluation API to CPython".
+
+   .. versionadded:: 3.9
+
+.. c:function:: void _PyInterpreterState_SetEvalFrameAllowSpecialization(PyInterpreterState *interp, int allow_specialization)
+
+   Enables or disables specialization why a custom frame evaluator is in place.
+
+   If *allow_specialization* is non-zero, the adaptive specializer will
+   continue to specialize bytecodes even though a custom eval frame function
+   is set. When *allow_specialization* is zero, setting a custom eval frame
+   disables specialization. The standard interpreter loop will continue to deopt
+   while a frame evaluation API is in place - the frame evaluation function needs
+   to handle the specialized opcodes to take advantage of this.
+
+   .. versionadded:: 3.15
+
+.. c:function:: int _PyInterpreterState_IsSpecializationEnabled(PyInterpreterState *interp)
+
+   Return non-zero if adaptive specialization is enabled for the interpreter.
+   Specialization is enabled when no custom eval frame function is set, or
+   when one is set with *allow_specialization* enabled.
+
+   .. versionadded:: 3.15

+
+All of the following functions must be called after :c:func:`Py_Initialize`.
+
+.. versionchanged:: 3.7
+   :c:func:`Py_Initialize()` now initializes the :term:`GIL`
+   and sets an :term:`attached thread state`.
+
+
+.. c:function:: PyInterpreterState* PyInterpreterState_New()
+
+   Create a new interpreter state object.  An :term:`attached thread state` is not needed,
+   but may optionally exist if it is necessary to serialize calls to this
+   function.
+
+   .. audit-event:: cpython.PyInterpreterState_New "" c.PyInterpreterState_New
+
+
+.. c:function:: void PyInterpreterState_Clear(PyInterpreterState *interp)
+
+   Reset all information in an interpreter state object.  There must be
+   an :term:`attached thread state` for the interpreter.
+
+   .. audit-event:: cpython.PyInterpreterState_Clear "" c.PyInterpreterState_Clear
+
+
+.. c:function:: void PyInterpreterState_Delete(PyInterpreterState *interp)
+
+   Destroy an interpreter state object.  There **should not** be an
+   :term:`attached thread state` for the target interpreter. The interpreter
+   state must have been reset with a previous call to :c:func:`PyInterpreterState_Clear`.
+
+
+.. _advanced-debugging:
+
+Advanced debugger support
+-------------------------
+
+These functions are only intended to be used by advanced debugging tools.

+
+   Return the interpreter state object at the head of the list of all such objects.
+
+
+.. c:function:: PyInterpreterState* PyInterpreterState_Main()
+
+   Return the main interpreter state object.
+
+

+
+   Return the pointer to the first :c:type:`PyThreadState` object in the list of
+   threads associated with the interpreter *interp*.
+
+
+.. c:function:: PyThreadState* PyThreadState_Next(PyThreadState *tstate)
+
+   Return the next thread state object after *tstate* from the list of all such
+   objects belonging to the same :c:type:`PyInterpreterState` object.

+==========================
+
+The C-API provides a basic mutual exclusion lock.
+
+.. c:type:: PyMutex
+
+   A mutual exclusion lock.  The :c:type:`!PyMutex` should be initialized to
+   zero to represent the unlocked state.  For example::
+
+      PyMutex mutex = {0};
+
+   Instances of :c:type:`!PyMutex` should not be copied or moved.  Both the
+   contents and address of a :c:type:`!PyMutex` are meaningful, and it must
+   remain at a fixed, writable location in memory.
+
+   .. note::
+
+      A :c:type:`!PyMutex` currently occupies one byte, but the size should be
+      considered unstable.  The size may change in future Python releases

+
+.. c:function:: void PyMutex_Lock(PyMutex *m)
+
+   Lock mutex *m*.  If another thread has already locked it, the calling

+   will temporarily detach the :term:`thread state <attached thread state>` if one exists.

+.. _python-critical-section-api:
+
+Python critical section API
+---------------------------
+
+The critical section API provides a deadlock avoidance layer on top of
+per-object locks for :term:`free-threaded <free threading>` CPython.  They are
+intended to replace reliance on the :term:`global interpreter lock`, and are
+no-ops in versions of Python with the global interpreter lock.
+
+Critical sections are intended to be used for custom types implemented
+in C-API extensions. They should generally not be used with built-in types like
+:class:`list` and :class:`dict` because their public C-APIs
+already use critical sections internally, with the notable
+exception of :c:func:`PyDict_Next`, which requires critical section
+to be acquired externally.
+
+Critical sections avoid deadlocks by implicitly suspending active critical
+sections, hence, they do not provide exclusive access such as provided by
+traditional locks like :c:type:`PyMutex`.  When a critical section is started,
+the per-object lock for the object is acquired. If the code executed inside the
+critical section calls C-API functions then it can suspend the critical section thereby
+releasing the per-object lock, so other threads can acquire the per-object lock
+for the same object.
+
+Variants that accept :c:type:`PyMutex` pointers rather than Python objects are also
+available. Use these variants to start a critical section in a situation where
+there is no :c:type:`PyObject` -- for example, when working with a C type that
+does not extend or wrap :c:type:`PyObject` but still needs to call into the C
+API in a manner that might lead to deadlocks.
+
+.. note::
+
+   Operations that need to lock two objects at once must use
+   :c:macro:`Py_BEGIN_CRITICAL_SECTION2`.  You *cannot* use nested critical
+   sections to lock more than one object at once, because the inner critical
+   section may suspend the outer critical sections.  This API does not provide
+   a way to lock more than two objects at once.
+
+Example usage::
+
+   static PyObject *
+   set_field(MyObject *self, PyObject *value)
+   {
+      Py_BEGIN_CRITICAL_SECTION(self);
+      Py_SETREF(self->field, Py_XNewRef(value));
+      Py_END_CRITICAL_SECTION();
+      Py_RETURN_NONE;
+   }
+
+In the above example, :c:macro:`Py_SETREF` calls :c:macro:`Py_DECREF`, which
+can call arbitrary code through an object's deallocation function.  The critical
+section API avoids potential deadlocks due to reentrancy and lock ordering
+by allowing the runtime to temporarily suspend the critical section if the
+code triggered by the finalizer blocks and calls :c:func:`PyEval_SaveThread`.

+Thread states and the global interpreter lock
+=============================================
+
+.. index::
+   single: global interpreter lock
+   single: interpreter lock
+   single: lock, interpreter
+
+Unless on a :term:`free-threaded build` of :term:`CPython`,
+the Python interpreter is generally not thread-safe.  In order to support
+multi-threaded Python programs, there's a global lock, called the :term:`global
+interpreter lock` or :term:`GIL`, that must be held by a thread before
+accessing Python objects. Without the lock, even the simplest operations
+could cause problems in a multi-threaded program: for example, when
+two threads simultaneously increment the reference count of the same object, the
+reference count could end up being incremented only once instead of twice.
+
+As such, only a thread that holds the GIL may operate on Python objects or
+invoke Python's C API.
+
+.. index:: single: setswitchinterval (in module sys)
+
+In order to emulate concurrency, the interpreter regularly tries to switch
+threads between bytecode instructions (see :func:`sys.setswitchinterval`).
+This is why locks are also necessary for thread-safety in pure-Python code.
+
+Additionally, the global interpreter lock is released around blocking I/O
+operations, such as reading or writing to a file. From the C API, this is done
+by :ref:`detaching the thread state <detaching-thread-state>`.
+
+
+.. index::
+   single: PyThreadState (C type)
+
+The Python interpreter keeps some thread-local information inside
+a data structure called :c:type:`PyThreadState`, known as a :term:`thread state`.
+Each thread has a thread-local pointer to a :c:type:`PyThreadState`; a thread state
+referenced by this pointer is considered to be :term:`attached <attached thread state>`.
+
+A thread can only have one :term:`attached thread state` at a time. An attached
+thread state is typically analogous with holding the GIL, except on
+free-threaded builds.  On builds with the GIL enabled, attaching a thread state
+will block until the GIL can be acquired. However, even on builds with the GIL
+disabled, it is still required to have an attached thread state, as the interpreter
+needs to keep track of which threads may access Python objects.
+
+.. note::
+
+   Even on the free-threaded build, attaching a thread state may block, as the
+   GIL can be re-enabled or threads might be temporarily suspended (such as during
+   a garbage collection).
+
+Generally, there will always be an attached thread state when using Python's
+C API, including during embedding and when implementing methods, so it's uncommon
+to need to set up a thread state on your own. Only in some specific cases, such
+as in a :c:macro:`Py_BEGIN_ALLOW_THREADS` block or in a fresh thread, will the
+thread not have an attached thread state.
+If uncertain, check if :c:func:`PyThreadState_GetUnchecked` returns ``NULL``.
+
+If it turns out that you do need to create a thread state, it is recommended to
+use :c:func:`PyThreadState_Ensure` or :c:func:`PyThreadState_EnsureFromView`,
+which will manage the thread state for you.
+
+
+.. _detaching-thread-state:
+
+Detaching the thread state from extension code
+----------------------------------------------
+
+Most extension code manipulating the :term:`thread state` has the following simple
+structure::
+
+   Save the thread state in a local variable.
+   ... Do some blocking I/O operation ...
+   Restore the thread state from the local variable.
+
+This is so common that a pair of macros exists to simplify it::
+
+   Py_BEGIN_ALLOW_THREADS
+   ... Do some blocking I/O operation ...
+   Py_END_ALLOW_THREADS
+
+.. index::
+   single: Py_BEGIN_ALLOW_THREADS (C macro)
+   single: Py_END_ALLOW_THREADS (C macro)
+
+The :c:macro:`Py_BEGIN_ALLOW_THREADS` macro opens a new block and declares a
+hidden local variable; the :c:macro:`Py_END_ALLOW_THREADS` macro closes the
+block.
+
+The block above expands to the following code::
+
+   PyThreadState *_save;
+
+   _save = PyEval_SaveThread();
+   ... Do some blocking I/O operation ...
+   PyEval_RestoreThread(_save);
+
+.. index::
+   single: PyEval_RestoreThread (C function)
+   single: PyEval_SaveThread (C function)
+
+Here is how these functions work:
+
+The attached thread state implies that the GIL is held for the interpreter.
+To detach it, :c:func:`PyEval_SaveThread` is called and the result is stored
+in a local variable.
+
+By detaching the thread state, the GIL is released, which allows other threads
+to attach to the interpreter and execute while the current thread performs
+blocking I/O. When the I/O operation is complete, the old thread state is
+reattached by calling :c:func:`PyEval_RestoreThread`, which will wait until
+the GIL can be acquired.
+
+.. note::
+   Performing blocking I/O is the most common use case for detaching
+   the thread state, but it is also useful to call it over long-running
+   native code that doesn't need access to Python objects or Python's C API.
+   For example, the standard :mod:`zlib` and :mod:`hashlib` modules detach the
+   :term:`thread state <attached thread state>` when compressing or hashing
+   data.
+
+On a :term:`free-threaded build`, the :term:`GIL` is usually out of the question,
+but **detaching the thread state is still required**, because the interpreter
+periodically needs to block all threads to get a consistent view of Python objects
+without the risk of race conditions.
+For example, CPython currently suspends all threads for a short period of time
+while running the garbage collector.
+
+.. warning::
+
+   Detaching the thread state can lead to unexpected behavior during interpreter
+   finalization. See :ref:`cautions-regarding-runtime-finalization` for more
+   details.
+
+
+APIs
+^^^^
+
+The following macros are normally used without a trailing semicolon; look for
+example usage in the Python source distribution.
+
+.. note::
+
+    These macros are still necessary on the :term:`free-threaded build` to prevent
+    deadlocks.
+
+.. c:macro:: Py_BEGIN_ALLOW_THREADS
+
+   This macro expands to ``{ PyThreadState *_save; _save = PyEval_SaveThread();``.
+   Note that it contains an opening brace; it must be matched with a following
+   :c:macro:`Py_END_ALLOW_THREADS` macro.  See above for further discussion of this
+   macro.
+
+
+.. c:macro:: Py_END_ALLOW_THREADS
+
+   This macro expands to ``PyEval_RestoreThread(_save); }``. Note that it contains
+   a closing brace; it must be matched with an earlier
+   :c:macro:`Py_BEGIN_ALLOW_THREADS` macro.  See above for further discussion of
+   this macro.
+
+
+.. c:macro:: Py_BLOCK_THREADS
+
+   This macro expands to ``PyEval_RestoreThread(_save);``: it is equivalent to
+   :c:macro:`Py_END_ALLOW_THREADS` without the closing brace.
+
+
+.. c:macro:: Py_UNBLOCK_THREADS
+
+   This macro expands to ``_save = PyEval_SaveThread();``: it is equivalent to
+   :c:macro:`Py_BEGIN_ALLOW_THREADS` without the opening brace and variable
+   declaration.
+
+
+.. _non-python-created-threads:
+.. _c-api-foreign-threads:
+
+
+Using the C API from foreign threads
+------------------------------------
+
+When threads are created using the dedicated Python APIs (such as the
+:mod:`threading` module), a thread state is automatically associated with them,
+However, when a thread is created from native code (for example, by a
+third-party library with its own thread management), it doesn't hold an
+attached thread state.
+
+If you need to call Python code from these threads (often this will be part
+of a callback API provided by the aforementioned third-party library),
+you must first register these threads with the interpreter by
+creating a new thread state and attaching it.
+
+The easiest way to do this is through :c:func:`PyThreadState_Ensure`
+or :c:func:`PyThreadState_EnsureFromView`.
+
+.. note::
+   These functions require an argument pointing to the desired
+   interpreter; such a pointer can be acquired via a call to
+   :c:func:`PyInterpreterGuard_FromCurrent` (for ``PyThreadState_Ensure``) or
+   :c:func:`PyInterpreterView_FromCurrent` (for ``PyThreadState_EnsureFromView``)
+   from the function that creates the thread. If no pointer is available (such
+   as when the given native thread library doesn't provide a data argument),
+   :c:func:`PyInterpreterView_FromMain` can be used to get a view for the main
+   interpreter, but note that this will make the code incompatible with
+   subinterpreters.
+
+
+For example::
+
+   // The return value of PyInterpreterGuard_FromCurrent() from the
+   // function that created this thread.
+   PyInterpreterGuard *guard = thread_data->guard;
+
+   // Create a new thread state for the interpreter.
+   PyThreadStateToken *token = PyThreadState_Ensure(guard);
+   if (token == NULL) {
+      PyInterpreterGuard_Close(guard);
+      return;
+   }
+
+   // We have a valid thread state -- perform Python actions here.
+   result = CallSomeFunction();
+   // Evaluate result or handle exceptions.
+
+   // Release the thread state. No calls to the C API are allowed beyond this
+   // point.
+   PyThreadState_Release(token);
+   PyInterpreterGuard_Close(guard);
+
+
+Keep in mind that calling ``PyThreadState_Ensure`` might not always create a new
+thread state, and calling ``PyThreadState_Release`` might not always detach it.
+These functions may reuse an existing attached thread state, or may re-attach
+a thread state that was previously attached for the current thread.
+
+.. seealso::
+   :pep:`788`
+
+.. _c-api-reuse-thread-state:
+
+Reusing a thread state across repeated calls
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Creating and destroying a :c:type:`PyThreadState` is not free, and is more
+expensive on a :term:`free-threaded build`.  A foreign thread that calls into
+the interpreter many times -- for example, a worker thread in a native thread
+pool -- should avoid creating a fresh thread state on every entry and
+destroying it on every exit.  Instead, set up one thread state when the thread
+starts (or lazily on its first call into Python), attach and detach it around
+each call, and tear it down once when the thread exits.
+
+Manage the thread state explicitly with :c:func:`PyThreadState_New`, attaching
+and detaching it with :c:func:`PyEval_RestoreThread` and
+:c:func:`PyEval_SaveThread`.  This happens in three distinct phases, at
+different points in the thread's life.
+
+When the thread starts, create one thread state for it.  ``interp`` is the
+target interpreter, captured by the code that created this thread while it held
+an attached thread state (for example via :c:func:`PyInterpreterState_Get`)::
+
+   PyThreadState *tstate = PyThreadState_New(interp);
+
+Then, on each call into Python -- which may happen many times over the thread's
+life -- attach the thread state, make the Python C API calls that require it,
+and detach again so the thread does not hold the GIL while off doing non-Python
+work::
+
+   PyEval_RestoreThread(tstate);
+   result = CallSomeFunction();  /* your Python C API calls go here */
+   PyEval_SaveThread();
+
+When the thread is finished calling into Python, destroy the thread state once::
+
+   PyEval_RestoreThread(tstate);
+   PyThreadState_Clear(tstate);
+   PyThreadState_DeleteCurrent();
+
+The general-purpose entry points for calling in from a foreign thread --
+:c:func:`PyThreadState_Ensure` and the older :c:func:`PyGILState_Ensure` -- do
+*not* guarantee a persistent thread state: their thread-state lifetime is
+deliberately implementation-defined, so a matched acquire/release pair may
+create and destroy a thread state each time.  Use :c:func:`PyThreadState_New`,
+as shown here, whenever you specifically want to reuse one thread state across
+calls.
+
+The code that created the foreign thread must arrange for the shutdown sequence
+to run before the thread exits, and before :c:func:`Py_FinalizeEx` is called.
+If interpreter finalization begins first, the shutdown
+:c:func:`PyEval_RestoreThread` call will hang the thread rather than return (see
+:ref:`cautions-regarding-runtime-finalization`).  If the thread exits without
+running the shutdown sequence, the thread state is leaked for the remainder of
+the process.
+
+.. _c-api-attach-detach:
+
+Attaching/detaching thread states
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. c:function:: PyThreadStateToken *PyThreadState_Ensure(PyInterpreterGuard *guard)
+
+   Ensure that the thread has an attached thread state for the
+   interpreter protected by *guard*, and thus can safely invoke that
+   interpreter.
+
+   It is OK to call this function if the thread already has an
+   attached thread state, as long as there is a subsequent call to
+   :c:func:`PyThreadState_Release` that matches this one (meaning that "nested"
+   calls to this function are permitted).
+
+   The function's effect (if any) will be reversed by the matching call to
+   :c:func:`PyThreadState_Release`.
+
+   On error, this function returns ``NULL`` *without* an exception set.
+   Do not call :c:func:`!PyThreadState_Release` in this case.
+
+   On success, this function returns a pointer value that must be passed
+   to the matching call to :c:func:`!PyThreadState_Release`.
+
+   The conditions in which this function creates a new :term:`thread state` are
+   considered unstable and implementation-dependent. If you need to control the
+   exact lifetime of a thread state, consider using :c:func:`PyThreadState_New`.
+   However, do not avoid this function solely on the basis that the lifetime
+   of the thread state may be inconsistent across versions; changes to this
+   function will be done with caution and in a backwards-compatible manner.
+   In particular, the saving of thread-local variables and similar state will
+   be retained across Python versions.
+
+   .. impl-detail::
+
+      The exact behavior of whether this function creates a new thread state is
+      described below, but be aware that this may change in the future.
+
+      First, this function checks if an attached thread state is present.
+      If there is, this function then checks if the interpreter of that
+      thread state matches the interpreter guarded by *guard*. If that is
+      the case, this function simply marks the thread state as being used
+      by a ``PyThreadState_Ensure`` call and returns.
+
+      If there is no attached thread state, then this function checks if any
+      thread state has been used by the current OS thread. (This is
+      returned by :c:func:`PyGILState_GetThisThreadState`.)
+      If there was, then this function checks if that thread state's interpreter
+      matches *guard*. If it does, it is re-attached and marked as used.
+
+      Otherwise, if both of the above cases fail, a new thread state is created
+      for *guard*. It is then attached and marked as owned by ``PyThreadState_Ensure``.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: PyThreadStateToken *PyThreadState_EnsureFromView(PyInterpreterView *view)
+
+   Get an attached thread state for the interpreter referenced by *view*.
+
+   The behavior and return value are the same as for :c:func:`PyThreadState_Ensure`;
+   additionally, if the function succeeds, the interpreter referenced by *view* will
+   be implicitly guarded. The guard will be released upon the corresponding
+   :c:func:`PyThreadState_Release` call.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: void PyThreadState_Release(PyThreadStateToken *token)
+
+   Undo a :c:func:`PyThreadState_Ensure` or
+   :c:func:`PyThreadState_EnsureFromView` call.
+
+   This must be called exactly once for each successful *Ensure* call, with
+   *token* set to that call's return value.
+
+   The state that was attached before the corresponding *Ensure* call
+   (if any) will be attached when :c:func:`PyThreadState_Release` returns.
+
+   The exact behavior of whether this function deletes a thread state is
+   considered unstable and implementation-dependent.
+
+   .. impl-detail::
+
+      Currently, this function will decrement an internal counter on the
+      attached thread state. If this counter ever reaches below zero, this
+      function emits a fatal error (via :c:func:`Py_FatalError`).
+
+      If the attached thread state is owned by ``PyThreadState_Ensure``, then the
+      attached thread state will be deallocated and deleted upon the internal counter
+      reaching zero. Otherwise, nothing happens when the counter reaches zero.
+
+   .. versionadded:: 3.15
+
+.. c:type:: PyThreadStateToken

+
+
+.. _legacy-api:
+.. _gilstate:
+
+GIL-state APIs
+--------------
+
+The following APIs are generally not compatible with subinterpreters and
+will hang the process during interpreter finalization (see
+:ref:`cautions-regarding-runtime-finalization`). As such, these APIs were
+:term:`soft deprecated` in Python 3.15 in favor of the :ref:`new APIs
+<c-api-foreign-threads>`.
+
+
+.. c:type:: PyGILState_STATE
+
+   The type of the value returned by :c:func:`PyGILState_Ensure` and passed to
+   :c:func:`PyGILState_Release`.
+
+   .. c:enumerator:: PyGILState_LOCKED
+
+      The GIL was already held when :c:func:`PyGILState_Ensure` was called.
+
+   .. c:enumerator:: PyGILState_UNLOCKED
+
+      The GIL was not held when :c:func:`PyGILState_Ensure` was called.
+
+
+.. c:function:: PyGILState_STATE PyGILState_Ensure()
+
+   Ensure that the current thread is ready to call the Python C API regardless
+   of the current state of Python, or of the :term:`attached thread state`. This may
+   be called as many times as desired by a thread as long as each call is
+   matched with a call to :c:func:`PyGILState_Release`. In general, other
+   thread-related APIs may be used between :c:func:`PyGILState_Ensure` and
+   :c:func:`PyGILState_Release` calls as long as the thread state is restored to
+   its previous state before the Release().  For example, normal usage of the
+   :c:macro:`Py_BEGIN_ALLOW_THREADS` and :c:macro:`Py_END_ALLOW_THREADS` macros is
+   acceptable.
+
+   The return value is an opaque "handle" to the :term:`attached thread state` when
+   :c:func:`PyGILState_Ensure` was called, and must be passed to
+   :c:func:`PyGILState_Release` to ensure Python is left in the same state. Even
+   though recursive calls are allowed, these handles *cannot* be shared - each
+   unique call to :c:func:`PyGILState_Ensure` must save the handle for its call
+   to :c:func:`PyGILState_Release`.
+
+   When the function returns, there will be an :term:`attached thread state`
+   and the thread will be able to call arbitrary Python code.
+
+   This function has no way to return an error. As such, errors are either fatal
+   (that is, they send ``SIGABRT`` and crash the process; see
+   :c:func:`Py_FatalError`), or the thread will be permanently blocked (such as
+   during interpreter finalization).
+
+   .. warning::
+      Calling this function when the interpreter is finalizing will
+      infinitely hang the thread, which may cause deadlocks.
+      :ref:`cautions-regarding-runtime-finalization` for more details.
+
+      In addition, this function generally does not work with subinterpreters
+      when used from foreign threads, because this function has no way of
+      knowing which interpreter created the thread (and as such, will implicitly
+      pick the main interpreter).

+
+   Release any resources previously acquired.  After this call, Python's state will
+   be the same as it was prior to the corresponding :c:func:`PyGILState_Ensure` call
+   (but generally this state will be unknown to the caller, hence the use of the
+   GIL-state API).
+
+   Every call to :c:func:`PyGILState_Ensure` must be matched by a call to
+   :c:func:`PyGILState_Release` on the same thread.

+   .. soft-deprecated:: 3.15
+      Use :c:func:`PyThreadState_Release` instead.
+
+
+.. c:function:: PyThreadState* PyGILState_GetThisThreadState()
+
+   Get the :term:`thread state` that was most recently :term:`attached
+   <attached thread state>` for this thread. (If the most recent thread state
+   has been deleted, this returns ``NULL``.)
+
+   If the caller has an attached thread state, it is returned.
+
+   In other terms, this function returns the thread state that will be used by
+   :c:func:`PyGILState_Ensure`. If this returns ``NULL``, then
+   ``PyGILState_Ensure`` will create a new thread state.
+
+   This function cannot fail.
+
+   .. soft-deprecated:: 3.15
+      Use :c:func:`PyThreadState_Get` or :c:func:`PyThreadState_GetUnchecked`
+      instead.
+
+
+.. c:function:: int PyGILState_Check()
+
+   Return ``1`` if the current thread has an :term:`attached thread state`
+   that matches the thread state returned by
+   :c:func:`PyGILState_GetThisThreadState`. If the caller has no attached thread
+   state or it otherwise doesn't match, then this returns ``0``.
+
+   If the current Python process has ever created a subinterpreter, this
+   function will *always* return ``1``.
+
+   This is mainly a helper/diagnostic function.
+
+   .. versionadded:: 3.4
+

+
+Cautions about fork()
+---------------------
+
+Another important thing to note about threads is their behaviour in the face
+of the C :c:func:`fork` call. On most systems with :c:func:`fork`, after a
+process forks only the thread that issued the fork will exist.  This has a
+concrete impact both on how locks must be handled and on all stored state
+in CPython's runtime.
+
+The fact that only the "current" thread remains
+means any locks held by other threads will never be released. Python solves
+this for :func:`os.fork` by acquiring the locks it uses internally before
+the fork, and releasing them afterwards. In addition, it resets any
+:ref:`lock-objects` in the child. When extending or embedding Python, there
+is no way to inform Python of additional (non-Python) locks that need to be
+acquired before or reset after a fork. OS facilities such as
+:c:func:`!pthread_atfork` would need to be used to accomplish the same thing.
+Additionally, when extending or embedding Python, calling :c:func:`fork`
+directly rather than through :func:`os.fork` (and returning to or calling
+into Python) may result in a deadlock by one of Python's internal locks
+being held by a thread that is defunct after the fork.
+:c:func:`PyOS_AfterFork_Child` tries to reset the necessary locks, but is not
+always able to.
+
+The fact that all other threads go away also means that CPython's
+runtime state there must be cleaned up properly, which :func:`os.fork`
+does.  This means finalizing all other :c:type:`PyThreadState` objects
+belonging to the current interpreter and all other
+:c:type:`PyInterpreterState` objects.  Due to this and the special
+nature of the :ref:`"main" interpreter <sub-interpreter-support>`,
+:c:func:`fork` should only be called in that interpreter's "main"
+thread, where the CPython global runtime was originally initialized.
+The only exception is if :c:func:`exec` will be called immediately
+after.

+High-level APIs
+---------------
+
+These are the most commonly used types and functions when writing multi-threaded
+C extensions.
+
+
+.. c:type:: PyThreadState
+
+   This data structure represents the state of a single thread.  The only public
+   data member is:
+
+   .. c:member:: PyInterpreterState *interp
+
+      This thread's interpreter state.
+
+
+.. c:function:: void PyEval_InitThreads()
+
+   .. index::
+      single: PyEval_AcquireThread()
+      single: PyEval_ReleaseThread()
+      single: PyEval_SaveThread()
+      single: PyEval_RestoreThread()
+
+   Deprecated function which does nothing.
+
+   In Python 3.6 and older, this function created the GIL if it didn't exist.
+
+   .. versionchanged:: 3.9
+      The function now does nothing.
+
+   .. versionchanged:: 3.7
+      This function is now called by :c:func:`Py_Initialize()`, so you don't
+      have to call it yourself anymore.
+
+   .. versionchanged:: 3.2
+      This function cannot be called before :c:func:`Py_Initialize()` anymore.
+
+   .. deprecated:: 3.9
+
+   .. index:: pair: module; _thread
+
+
+.. c:function:: PyThreadState* PyEval_SaveThread()
+
+   Detach the :term:`attached thread state` and return it.
+   The thread will have no :term:`thread state` upon returning.
+
+
+.. c:function:: void PyEval_RestoreThread(PyThreadState *tstate)
+
+   Set the :term:`attached thread state` to *tstate*.
+   The passed :term:`thread state` **should not** be :term:`attached <attached thread state>`,
+   otherwise deadlock ensues. *tstate* will be attached upon returning.
+
+   .. note::
+      Calling this function from a thread when the runtime is finalizing will
+      hang the thread until the program exits, even if the thread was not
+      created by Python.  Refer to
+      :ref:`cautions-regarding-runtime-finalization` for more details.
+
+   .. versionchanged:: 3.14
+      Hangs the current thread, rather than terminating it, if called while the
+      interpreter is finalizing.
+
+.. c:function:: PyThreadState* PyThreadState_Get()
+
+   Return the :term:`attached thread state`. If the thread has no attached
+   thread state, (such as when inside of :c:macro:`Py_BEGIN_ALLOW_THREADS`
+   block), then this issues a fatal error (so that the caller needn't check
+   for ``NULL``).
+
+   See also :c:func:`PyThreadState_GetUnchecked`.
+
+.. c:function:: PyThreadState* PyThreadState_GetUnchecked()
+
+   Similar to :c:func:`PyThreadState_Get`, but don't kill the process with a
+   fatal error if it is NULL. The caller is responsible to check if the result
+   is NULL.
+
+   .. versionadded:: 3.13
+      In Python 3.5 to 3.12, the function was private and known as
+      ``_PyThreadState_UncheckedGet()``.
+
+
+.. c:function:: PyThreadState* PyThreadState_Swap(PyThreadState *tstate)
+
+   Set the :term:`attached thread state` to *tstate*, and return the
+   :term:`thread state` that was attached prior to calling.
+
+   This function is safe to call without an :term:`attached thread state`; it
+   will simply return ``NULL`` indicating that there was no prior thread state.
+
+   .. seealso::
+      :c:func:`PyEval_ReleaseThread`
+
+   .. note::
+      Similar to :c:func:`PyGILState_Ensure`, this function will hang the

+
+
+Low-level APIs
+--------------
+
+.. c:function:: PyThreadState* PyThreadState_New(PyInterpreterState *interp)
+
+   Create a new thread state object belonging to the given interpreter object.
+   An :term:`attached thread state` is not needed.
+
+.. c:function:: void PyThreadState_Clear(PyThreadState *tstate)
+
+   Reset all information in a :term:`thread state` object.  *tstate*
+   must be :term:`attached <attached thread state>`
+
+   .. versionchanged:: 3.9
+      This function now calls the :c:member:`!PyThreadState.on_delete` callback.
+      Previously, that happened in :c:func:`PyThreadState_Delete`.
+
+   .. versionchanged:: 3.13
+      The :c:member:`!PyThreadState.on_delete` callback was removed.
+
+
+.. c:function:: void PyThreadState_Delete(PyThreadState *tstate)
+
+   Destroy a :term:`thread state` object.  *tstate* should not
+   be :term:`attached <attached thread state>` to any thread.
+   *tstate* must have been reset with a previous call to
+   :c:func:`PyThreadState_Clear`.
+
+
+.. c:function:: void PyThreadState_DeleteCurrent(void)
+
+   Detach the :term:`attached thread state` (which must have been reset
+   with a previous call to :c:func:`PyThreadState_Clear`) and then destroy it.
+
+   No :term:`thread state` will be :term:`attached <attached thread state>` upon
+   returning.
+
+.. c:function:: PyFrameObject* PyThreadState_GetFrame(PyThreadState *tstate)
+
+   Get the current frame of the Python thread state *tstate*.
+
+   Return a :term:`strong reference`. Return ``NULL`` if no frame is currently
+   executing.
+
+   See also :c:func:`PyEval_GetFrame`.
+
+   *tstate* must not be ``NULL``, and must be :term:`attached <attached thread state>`.
+
+   .. versionadded:: 3.9
+
+
+.. c:function:: uint64_t PyThreadState_GetID(PyThreadState *tstate)
+
+   Get the unique :term:`thread state` identifier of the Python thread state *tstate*.
+
+   *tstate* must not be ``NULL``, and must be :term:`attached <attached thread state>`.
+
+   .. versionadded:: 3.9
+
+
+.. c:function:: PyInterpreterState* PyThreadState_GetInterpreter(PyThreadState *tstate)
+
+   Get the interpreter of the Python thread state *tstate*.
+
+   *tstate* must not be ``NULL``, and must be :term:`attached <attached thread state>`.
+
+   .. versionadded:: 3.9
+
+
+.. c:function:: void PyThreadState_EnterTracing(PyThreadState *tstate)
+
+   Suspend tracing and profiling in the Python thread state *tstate*.
+
+   Resume them using the :c:func:`PyThreadState_LeaveTracing` function.
+
+   .. versionadded:: 3.11
+
+
+.. c:function:: void PyThreadState_LeaveTracing(PyThreadState *tstate)
+
+   Resume tracing and profiling in the Python thread state *tstate* suspended
+   by the :c:func:`PyThreadState_EnterTracing` function.
+
+   See also :c:func:`PyEval_SetTrace` and :c:func:`PyEval_SetProfile`
+   functions.
+
+   .. versionadded:: 3.11
+
+
+.. c:function:: int PyUnstable_ThreadState_SetStackProtection(PyThreadState *tstate, void *stack_start_addr, size_t stack_size)
+
+   Set the stack protection start address and stack protection size
+   of a Python thread state.
+
+   On success, return ``0``.
+   On failure, set an exception and return ``-1``.
+
+   CPython implements :ref:`recursion control <recursion>` for C code by raising
+   :py:exc:`RecursionError` when it notices that the machine execution stack is close
+   to overflow. See for example the :c:func:`Py_EnterRecursiveCall` function.
+   For this, it needs to know the location of the current thread's stack, which it
+   normally gets from the operating system.
+   When the stack is changed, for example using context switching techniques like the
+   Boost library's ``boost::context``, you must call
+   :c:func:`~PyUnstable_ThreadState_SetStackProtection` to inform CPython of the change.
+
+   Call :c:func:`~PyUnstable_ThreadState_SetStackProtection` either before
+   or after changing the stack.
+   Do not call any other Python C API between the call and the stack
+   change.
+
+   See :c:func:`PyUnstable_ThreadState_ResetStackProtection` for undoing this operation.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: void PyUnstable_ThreadState_ResetStackProtection(PyThreadState *tstate)
+
+   Reset the stack protection start address and stack protection size
+   of a Python thread state to the operating system defaults.
+
+   See :c:func:`PyUnstable_ThreadState_SetStackProtection` for an explanation.
+
+   .. versionadded:: 3.15
+
+
+.. c:function:: PyObject* PyThreadState_GetDict()
+
+   Return a dictionary in which extensions can store thread-specific state
+   information.  Each extension should use a unique key to store a state in
+   the dictionary.  It is okay to call this function when no :term:`thread state`
+   is :term:`attached <attached thread state>`. If this function returns
+   ``NULL`` and no exception has been raised, then the caller should assume no
+   thread state is attached.
+
+
+.. c:function:: void PyEval_AcquireThread(PyThreadState *tstate)
+
+   :term:`Attach <attached thread state>` *tstate* to the current thread,
+   which must not be ``NULL`` or already :term:`attached <attached thread state>`.
+
+   The calling thread must not already have an :term:`attached thread state`.
+
+   .. note::
+      Calling this function from a thread when the runtime is finalizing will
+      hang the thread until the program exits, even if the thread was not
+      created by Python.  Refer to
+      :ref:`cautions-regarding-runtime-finalization` for more details.
+
+   .. versionchanged:: 3.8
+      Updated to be consistent with :c:func:`PyEval_RestoreThread`,
+      :c:func:`Py_END_ALLOW_THREADS`, and :c:func:`PyGILState_Ensure`,
+      and terminate the current thread if called while the interpreter is finalizing.
+
+   .. versionchanged:: 3.14
+      Hangs the current thread, rather than terminating it, if called while the
+      interpreter is finalizing.
+
+   :c:func:`PyEval_RestoreThread` is a higher-level function which is always
+   available (even when threads have not been initialized).
+
+
+.. c:function:: void PyEval_ReleaseThread(PyThreadState *tstate)
+
+   Detach the :term:`attached thread state`.
+   The *tstate* argument, which must not be ``NULL``, is only used to check
+   that it represents the :term:`attached thread state` --- if it isn't, a fatal error is
+   reported.
+
+   :c:func:`PyEval_SaveThread` is a higher-level function which is always
+   available (even when threads have not been initialized).
+
+
+Asynchronous notifications
+==========================
+
+A mechanism is provided to make asynchronous notifications to the main
+interpreter thread.  These notifications take the form of a function
+pointer and a void pointer argument.
+
+
+.. c:function:: int Py_AddPendingCall(int (*func)(void *), void *arg)
+
+   Schedule a function to be called from the main interpreter thread.  On
+   success, ``0`` is returned and *func* is queued for being called in the
+   main thread.  On failure, ``-1`` is returned without setting any exception.
+
+   When successfully queued, *func* will be *eventually* called from the
+   main interpreter thread with the argument *arg*.  It will be called
+   asynchronously with respect to normally running Python code, but with
+   both these conditions met:
+
+   * on a :term:`bytecode` boundary;
+   * with the main thread holding an :term:`attached thread state`
+     (*func* can therefore use the full C API).
+
+   *func* must return ``0`` on success, or ``-1`` on failure with an exception
+   set.  *func* won't be interrupted to perform another asynchronous
+   notification recursively, but it can still be interrupted to switch
+   threads if the :term:`thread state <attached thread state>` is detached.
+
+   This function doesn't need an :term:`attached thread state`. However, to call this
+   function in a subinterpreter, the caller must have an :term:`attached thread state`.
+   Otherwise, the function *func* can be scheduled to be called from the wrong interpreter.
+
+   .. warning::
+      This is a low-level function, only useful for very special cases.
+      There is no guarantee that *func* will be called as quick as
+      possible.  If the main thread is busy executing a system call,
+      *func* won't be called before the system call returns.  This
+      function is generally **not** suitable for calling Python code from
+      arbitrary C threads.  Instead, use :c:func:`PyThreadState_EnsureFromView`.
+
+   .. versionadded:: 3.1
+
+   .. versionchanged:: 3.9
+      If this function is called in a subinterpreter, the function *func* is
+      now scheduled to be called from the subinterpreter, rather than being
+      called from the main interpreter. Each subinterpreter now has its own
+      list of scheduled calls.
+
+   .. versionchanged:: 3.12
+      This function now always schedules *func* to be run in the main
+      interpreter.
+
+
+.. c:function:: int Py_MakePendingCalls(void)
+
+   Execute all pending calls. This is usually executed automatically by the
+   interpreter.
+
+   This function returns ``0`` on success, and returns ``-1`` with an exception
+   set on failure.
+
+   If this is not called in the main thread of the main
+   interpreter, this function does nothing and returns ``0``.
+   The caller must hold an :term:`attached thread state`.
+
+   .. versionadded:: 3.1
+
+   .. versionchanged:: 3.12
+      This function only runs pending calls in the main interpreter.
+
+
+.. c:function:: int PyThreadState_SetAsyncExc(unsigned long id, PyObject *exc)
+
+   Schedule an exception to be raised asynchronously in a thread.
+   If the thread has a previously scheduled exception, it is overwritten.
+
+   The *id* argument is the thread id of the target thread, as returned by
+   :c:func:`PyThread_get_thread_ident`.
+   *exc* is the class of the exception to be raised, or ``NULL`` to clear
+   the pending exception (if any).
+
+   Return the number of affected thread states.
+   This is normally ``1`` if *id* is found, even when no change was
+   made (the given *exc* was already pending, or *exc* is ``NULL`` but
+   no exception is pending).
+   If the thread id isn't found, return ``0``.  This raises no exceptions.
+
+   To prevent naive misuse, you must write your own C extension to call this.
+   This function must be called with an :term:`attached thread state`.
+   This function does not :term:`steal` any references to *exc*.
+   This function does not necessarily interrupt system calls such as
+   :py:func:`~time.sleep`.
+
+   .. versionchanged:: 3.7
+      The type of the *id* parameter changed from :c:expr:`long` to
+      :c:expr:`unsigned long`.
+
+
+Operating system thread APIs
+============================
+
+.. c:macro:: PYTHREAD_INVALID_THREAD_ID
+
+   Sentinel value for an invalid thread ID.
+
+   This is currently equivalent to ``(unsigned long)-1``.
+
+
+.. c:function:: unsigned long PyThread_start_new_thread(void (*func)(void *), void *arg)
+
+   Start function *func* in a new thread with argument *arg*.
+   The resulting thread is not intended to be joined.
+
+   *func* must not be ``NULL``, but *arg* may be ``NULL``.
+
+   On success, this function returns the identifier of the new thread; on failure,
+   this returns :c:macro:`PYTHREAD_INVALID_THREAD_ID`.
+
+   The caller does not need to hold an :term:`attached thread state`.
+
+
+.. c:function:: unsigned long PyThread_get_thread_ident(void)
+
+   Return the identifier of the current thread, which will never be zero.
+
+   This function cannot fail, and the caller does not need to hold an
+   :term:`attached thread state`.
+
+   .. seealso::
+      :py:func:`threading.get_ident` and :py:attr:`threading.Thread.ident`
+      expose this identifier to Python.
+
+
+.. c:function:: PyObject *PyThread_GetInfo(void)
+
+   Get general information about the current thread in the form of a
+   :ref:`struct sequence <struct-sequence-objects>` object. This information is
+   accessible as :py:attr:`sys.thread_info` in Python.
+
+   On success, this returns a new :term:`strong reference` to the thread
+   information; on failure, this returns ``NULL`` with an exception set.
+
+   The caller must hold an :term:`attached thread state`.
+
+
+.. c:macro:: PY_HAVE_THREAD_NATIVE_ID
+
+   This macro is defined when the system supports native thread IDs.
+
+
+.. c:function:: unsigned long PyThread_get_thread_native_id(void)
+
+   Get the native identifier of the current thread as it was assigned by the operating
+   system's kernel, which will never be less than zero.
+
+   This function is only available when :c:macro:`PY_HAVE_THREAD_NATIVE_ID` is
+   defined.
+
+   This function cannot fail, and the caller does not need to hold an
+   :term:`attached thread state`.
+
+   .. seealso::
+      :py:func:`threading.get_native_id`
+
+
+.. c:function:: void PyThread_exit_thread(void)
+
+   Terminate the current thread. This function is generally considered unsafe
+   and should be avoided. It is kept solely for backwards compatibility.
+
+   This function is only safe to call if all functions in the full call
+   stack are written to safely allow it.
+
+   .. warning::
+
+      If the current system uses POSIX threads (also known as "pthreads"),
+      this calls :manpage:`pthread_exit(3)`, which attempts to unwind the stack
+      and call C++ destructors on some libc implementations. However, if a
+      ``noexcept`` function is reached, it may terminate the process.
+      Other systems, such as macOS, do unwinding.
+
+      On Windows, this function calls ``_endthreadex()``, which kills the thread
+      without calling C++ destructors.
+
+      In any case, there is a risk of corruption on the thread's stack.
+
+   .. deprecated:: 3.14
+
+
+.. c:function:: void PyThread_init_thread(void)
+
+   Initialize ``PyThread*`` APIs. Python executes this function automatically,
+   so there's little need to call it from an extension module.
+
+
+.. c:function:: int PyThread_set_stacksize(size_t size)
+
+   Set the stack size of the current thread to *size* bytes.
+
+   This function returns ``0`` on success, ``-1`` if *size* is invalid, or
+   ``-2`` if the system does not support changing the stack size. This function
+   does not set exceptions.
+
+   The caller does not need to hold an :term:`attached thread state`.
+
+
+.. c:function:: size_t PyThread_get_stacksize(void)
+
+   Return the stack size of the current thread in bytes, or ``0`` if the system's
+   default stack size is in use.
+
+   The caller does not need to hold an :term:`attached thread state`.

+
+.. _thread-local-storage:
+
+Thread-local storage support
+============================
+
+The Python interpreter provides low-level support for thread-local storage
+(TLS) which wraps the underlying native TLS implementation to support the
+Python-level thread-local storage API (:class:`threading.local`).  The
+CPython C level APIs are similar to those offered by pthreads and Windows:
+use a thread key and functions to associate a :c:expr:`void*` value per
+thread.
+
+A :term:`thread state` does *not* need to be :term:`attached <attached thread state>`
+when calling these functions; they supply their own locking.
+
+Note that :file:`Python.h` does not include the declaration of the TLS APIs,
+you need to include :file:`pythread.h` to use thread-local storage.
+
+.. note::
+   None of these API functions handle memory management on behalf of the
+   :c:expr:`void*` values.  You need to allocate and deallocate them yourself.
+   If the :c:expr:`void*` values happen to be :c:expr:`PyObject*`, these
+   functions don't do refcount operations on them either.
+
+.. _thread-specific-storage-api:
+
+Thread-specific storage API
+---------------------------
+
+The thread-specific storage (TSS) API was introduced to supersede the use of the existing TLS API within the
+CPython interpreter.  This API uses a new type :c:type:`Py_tss_t` instead of
+:c:expr:`int` to represent thread keys.
+
+.. versionadded:: 3.7
+
+.. seealso:: "A New C-API for Thread-Local Storage in CPython" (:pep:`539`)
+
+
+.. c:type:: Py_tss_t
+
+   This data structure represents the state of a thread key, the definition of
+   which may depend on the underlying TLS implementation, and it has an
+   internal field representing the key's initialization state.  There are no
+   public members in this structure.
+
+   When :ref:`Py_LIMITED_API <stable>` is not defined, static allocation of
+   this type by :c:macro:`Py_tss_NEEDS_INIT` is allowed.
+
+
+.. c:macro:: Py_tss_NEEDS_INIT
+
+   This macro expands to the initializer for :c:type:`Py_tss_t` variables.
+   Note that this macro won't be defined with :ref:`Py_LIMITED_API <stable>`.
+
+
+Dynamic allocation
+------------------
+
+Dynamic allocation of the :c:type:`Py_tss_t`, required in extension modules
+built with :ref:`Py_LIMITED_API <stable>`, where static allocation of this type
+is not possible due to its implementation being opaque at build time.
+
+
+.. c:function:: Py_tss_t* PyThread_tss_alloc()
+
+   Return a value which is the same state as a value initialized with
+   :c:macro:`Py_tss_NEEDS_INIT`, or ``NULL`` in the case of dynamic allocation
+   failure.
+
+
+.. c:function:: void PyThread_tss_free(Py_tss_t *key)
+
+   Free the given *key* allocated by :c:func:`PyThread_tss_alloc`, after
+   first calling :c:func:`PyThread_tss_delete` to ensure any associated
+   thread locals have been unassigned. This is a no-op if the *key*
+   argument is ``NULL``.
+
+   .. note::
+      A freed key becomes a dangling pointer. You should reset the key to
+      ``NULL``.
+
+
+Methods
+-------
+
+The parameter *key* of these functions must not be ``NULL``.  Moreover, the
+behaviors of :c:func:`PyThread_tss_set` and :c:func:`PyThread_tss_get` are
+undefined if the given :c:type:`Py_tss_t` has not been initialized by
+:c:func:`PyThread_tss_create`.
+
+
+.. c:function:: int PyThread_tss_is_created(Py_tss_t *key)
+
+   Return a non-zero value if the given :c:type:`Py_tss_t` has been initialized
+   by :c:func:`PyThread_tss_create`.
+
+
+.. c:function:: int PyThread_tss_create(Py_tss_t *key)
+
+   Return a zero value on successful initialization of a TSS key.  The behavior
+   is undefined if the value pointed to by the *key* argument is not
+   initialized by :c:macro:`Py_tss_NEEDS_INIT`.  This function can be called
+   repeatedly on the same key -- calling it on an already initialized key is a
+   no-op and immediately returns success.
+
+
+.. c:function:: void PyThread_tss_delete(Py_tss_t *key)
+

-       the linked list (what *tp_weaklist* points to) must **not** be

 .. _extending-intro:
 
-******************************
-Extending Python with C or C++
-******************************
+********************************
+Using the C API: Assorted topics
+********************************
 
-It is quite easy to add new built-in modules to Python, if you know how to
-program in C.  Such :dfn:`extension modules` can do two things that can't be
-done directly in Python: they can implement new built-in object types, and they
-can call C library functions and system calls.
-
-To support extensions, the Python API (Application Programmers Interface)
-defines a set of functions, macros and variables that provide access to most
-aspects of the Python run-time system.  The Python API is incorporated in a C
-source file by including the header ``"Python.h"``.
-
-The compilation of an extension module depends on its intended use as well as on
-your system setup; details are given in later chapters.
-
-.. note::
-
-   The C extension interface is specific to CPython, and extension modules do
-   not work on other Python implementations.  In many cases, it is possible to
-   avoid writing C extensions and preserve portability to other implementations.
-   For example, if your use case is calling C library functions or system calls,
-   you should consider using the :mod:`ctypes` module or the `cffi
-   <https://cffi.readthedocs.io/>`_ library rather than writing
-   custom C code.
-   These modules let you write Python code to interface with C code and are more
-   portable between implementations of Python than writing and compiling a C
-   extension module.
-
-
-.. _extending-simpleexample:
-
-A Simple Example
-================
-
-Let's create an extension module called ``spam`` (the favorite food of Monty
-Python fans...) and let's say we want to create a Python interface to the C
-library function :c:func:`system` [#]_. This function takes a null-terminated
-character string as argument and returns an integer.  We want this function to
-be callable from Python as follows:
-
-.. code-block:: pycon
-
-   >>> import spam
-   >>> status = spam.system("ls -l")
-
-Begin by creating a file :file:`spammodule.c`.  (Historically, if a module is
-called ``spam``, the C file containing its implementation is called
-:file:`spammodule.c`; if the module name is very long, like ``spammify``, the
-module name can be just :file:`spammify.c`.)
-
-The first two lines of our file can be::
-
-   #define PY_SSIZE_T_CLEAN
-   #include <Python.h>
-
-which pulls in the Python API (you can add a comment describing the purpose of
-the module and a copyright notice if you like).
-
-.. note::
-
-   Since Python may define some pre-processor definitions which affect the standard
-   headers on some systems, you *must* include :file:`Python.h` before any standard
-   headers are included.
-
-   ``#define PY_SSIZE_T_CLEAN`` was used to indicate that ``Py_ssize_t`` should be
-   used in some APIs instead of ``int``.
-   It is not necessary since Python 3.13, but we keep it here for backward compatibility.
-   See :ref:`arg-parsing-string-and-buffers` for a description of this macro.
-
-All user-visible symbols defined by :file:`Python.h` have a prefix of ``Py`` or
-``PY``, except those defined in standard header files.
-
-.. tip::
-
-   For backward compatibility, :file:`Python.h` includes several standard header files.
-   C extensions should include the standard headers that they use,
-   and should not rely on these implicit includes.
-   If using the limited C API version 3.13 or newer, the implicit includes are:
-
-   * ``<assert.h>``
-   * ``<intrin.h>`` (on Windows)
-   * ``<inttypes.h>``
-   * ``<limits.h>``
-   * ``<math.h>``
-   * ``<stdarg.h>``
-   * ``<wchar.h>``
-   * ``<sys/types.h>`` (if present)
-
-   If :c:macro:`Py_LIMITED_API` is not defined, or is set to version 3.12 or older,
-   the headers below are also included:
-
-   * ``<ctype.h>``
-   * ``<unistd.h>`` (on POSIX)
-
-   If :c:macro:`Py_LIMITED_API` is not defined, or is set to version 3.10 or older,
-   the headers below are also included:
-
-   * ``<errno.h>``
-   * ``<stdio.h>``
-   * ``<stdlib.h>``
-   * ``<string.h>``
-
-The next thing we add to our module file is the C function that will be called
-when the Python expression ``spam.system(string)`` is evaluated (we'll see
-shortly how it ends up being called)::
-
-   static PyObject *
-   spam_system(PyObject *self, PyObject *args)
-   {
-       const char *command;
-       int sts;
-
-       if (!PyArg_ParseTuple(args, "s", &command))
-           return NULL;
-       sts = system(command);
-       return PyLong_FromLong(sts);
-   }
-
-There is a straightforward translation from the argument list in Python (for
-example, the single expression ``"ls -l"``) to the arguments passed to the C
-function.  The C function always has two arguments, conventionally named *self*
-and *args*.
-
-The *self* argument points to the module object for module-level functions;
-for a method it would point to the object instance.
-
-The *args* argument will be a pointer to a Python tuple object containing the
-arguments.  Each item of the tuple corresponds to an argument in the call's
-argument list.  The arguments are Python objects --- in order to do anything
-with them in our C function we have to convert them to C values.  The function
-:c:func:`PyArg_ParseTuple` in the Python API checks the argument types and
-converts them to C values.  It uses a template string to determine the required
-types of the arguments as well as the types of the C variables into which to
-store the converted values.  More about this later.
-
-:c:func:`PyArg_ParseTuple` returns true (nonzero) if all arguments have the right
-type and its components have been stored in the variables whose addresses are
-passed.  It returns false (zero) if an invalid argument list was passed.  In the
-latter case it also raises an appropriate exception so the calling function can
-return ``NULL`` immediately (as we saw in the example).
+The :ref:`tutorial <first-extension-module>` walked you through
+creating a C API extension module, but left many areas unexplained.
+This document looks at several concepts that you'll need to learn
+in order to write more complex extensions.

-Back to the Example
-===================
-
-Going back to our example function, you should now be able to understand this
-statement::
-
-   if (!PyArg_ParseTuple(args, "s", &command))
-       return NULL;
-
-It returns ``NULL`` (the error indicator for functions returning object pointers)
-if an error is detected in the argument list, relying on the exception set by
-:c:func:`PyArg_ParseTuple`.  Otherwise the string value of the argument has been
-copied to the local variable :c:data:`!command`.  This is a pointer assignment and
-you are not supposed to modify the string to which it points (so in Standard C,
-the variable :c:data:`!command` should properly be declared as ``const char
-*command``).
-
-The next statement is a call to the Unix function :c:func:`system`, passing it
-the string we just got from :c:func:`PyArg_ParseTuple`::
-
-   sts = system(command);
-
-Our :func:`!spam.system` function must return the value of :c:data:`!sts` as a
-Python object.  This is done using the function :c:func:`PyLong_FromLong`. ::
-
-   return PyLong_FromLong(sts);
-
-In this case, it will return an integer object.  (Yes, even integers are objects
-on the heap in Python!)
-
-If you have a C function that returns no useful argument (a function returning
-:c:expr:`void`), the corresponding Python function must return ``None``.   You
-need this idiom to do so (which is implemented by the :c:macro:`Py_RETURN_NONE`
-macro)::
-
-   Py_INCREF(Py_None);
-   return Py_None;
-
-:c:data:`Py_None` is the C name for the special Python object ``None``.  It is a
-genuine Python object rather than a ``NULL`` pointer, which means "error" in most
-contexts, as we have seen.

-First, we need to list its name and address in a "method table"::
-
-   static PyMethodDef spam_methods[] = {
-       ...
-       {"system",  spam_system, METH_VARARGS,
-        "Execute a shell command."},
-       ...
-       {NULL, NULL, 0, NULL}        /* Sentinel */
-   };
-
-Note the third entry (``METH_VARARGS``).  This is a flag telling the interpreter
-the calling convention to be used for the C function.  It should normally always
-be ``METH_VARARGS`` or ``METH_VARARGS | METH_KEYWORDS``; a value of ``0`` means
-that an obsolete variant of :c:func:`PyArg_ParseTuple` is used.
-
-When using only ``METH_VARARGS``, the function should expect the Python-level
-parameters to be passed in as a tuple acceptable for parsing via
-:c:func:`PyArg_ParseTuple`; more information on this function is provided below.
-
-The :c:macro:`METH_KEYWORDS` bit may be set in the third field if keyword
-arguments should be passed to the function.  In this case, the C function should
-accept a third ``PyObject *`` parameter which will be a dictionary of keywords.
-Use :c:func:`PyArg_ParseTupleAndKeywords` to parse the arguments to such a
-function.
-
-The method table must be referenced in the module definition structure::
-
-   static struct PyModuleDef spam_module = {
-       ...
-       .m_methods = spam_methods,
-       ...
-   };
-
-This structure, in turn, must be passed to the interpreter in the module's
-initialization function.  The initialization function must be named
-:c:func:`!PyInit_name`, where *name* is the name of the module, and should be the
-only non-\ ``static`` item defined in the module file::
-
-   PyMODINIT_FUNC
-   PyInit_spam(void)
-   {
-       return PyModuleDef_Init(&spam_module);
-   }
-
-Note that :c:macro:`PyMODINIT_FUNC` declares the function as ``PyObject *`` return type,
-declares any special linkage declarations required by the platform, and for C++
-declares the function as ``extern "C"``.
-
-:c:func:`!PyInit_spam` is called when each interpreter imports its module
-:mod:`!spam` for the first time.  (See below for comments about embedding Python.)
-A pointer to the module definition must be returned via :c:func:`PyModuleDef_Init`,
-so that the import machinery can create the module and store it in ``sys.modules``.
-
-When embedding Python, the :c:func:`!PyInit_spam` function is not called
-automatically unless there's an entry in the :c:data:`!PyImport_Inittab` table.
-To add the module to the initialization table, use :c:func:`PyImport_AppendInittab`,
-optionally followed by an import of the module::
-
-   #define PY_SSIZE_T_CLEAN
-   #include <Python.h>
-
-   int
-   main(int argc, char *argv[])
-   {
-       PyStatus status;
-       PyConfig config;
-       PyConfig_InitPythonConfig(&config);
-
-       /* Add a built-in module, before Py_Initialize */
-       if (PyImport_AppendInittab("spam", PyInit_spam) == -1) {
-           fprintf(stderr, "Error: could not extend in-built modules table\n");
-           exit(1);
-       }
-
-       /* Pass argv[0] to the Python interpreter */
-       status = PyConfig_SetBytesString(&config, &config.program_name, argv[0]);
-       if (PyStatus_Exception(status)) {
-           goto exception;
-       }
-
-       /* Initialize the Python interpreter.  Required.
-          If this step fails, it will be a fatal error. */
-       status = Py_InitializeFromConfig(&config);
-       if (PyStatus_Exception(status)) {
-           goto exception;
-       }
-       PyConfig_Clear(&config);
-
-       /* Optionally import the module; alternatively,
-          import can be deferred until the embedded script
-          imports it. */
-       PyObject *pmodule = PyImport_ImportModule("spam");
-       if (!pmodule) {
-           PyErr_Print();
-           fprintf(stderr, "Error: could not import module 'spam'\n");
-       }
-
-       // ... use Python C API here ...
-
-       return 0;
-
-     exception:
-        PyConfig_Clear(&config);
-        Py_ExitStatusException(status);
-   }
-
-.. note::
-
-   If you declare a global variable or a local static one, the module may
-   experience unintended side-effects on re-initialisation, for example when
-   removing entries from ``sys.modules`` or importing compiled modules into
-   multiple interpreters within a process
-   (or following a :c:func:`fork` without an intervening :c:func:`exec`).
-   If module state is not yet fully :ref:`isolated <isolating-extensions-howto>`,

+*********************************
+Your first C API extension module
+*********************************
+
+This tutorial will take you through creating a simple
+Python extension module written in C or C++.
+
+We will use the low-level Python C API directly.
+For easier ways to create extension modules, see
+the :ref:`recommended third party tools <c-api-tools>`.
+
+The tutorial assumes basic knowledge about Python: you should be able to
+define functions in Python code before starting to write them in C.
+See :ref:`tutorial-index` for an introduction to Python itself.
+
+The tutorial should be approachable for anyone who can write a basic C library.
+While we will mention several concepts that a C beginner would not be expected
+to know, like ``static`` functions or linkage declarations, understanding these
+is not necessary for success.
+
+We will focus on giving you a "feel" of what Python's C API is like.
+It will not teach you important concepts, like error handling
+and reference counting, which are covered in later chapters.
+
+We will assume that you use a Unix-like system (including macOS and
+Linux), or Windows.
+On other systems, you might need to adjust some details -- for example,
+a system command name.
+
+You need to have a suitable C compiler and Python development headers installed.
+On Linux, headers are often in a package like ``python3-dev``
+or ``python3-devel``.
+
+You need to be able to install Python packages.
+This tutorial uses `pip <https://pip.pypa.io/>`__ (``pip install``), but you
+can substitute any tool that can build and install ``pyproject.toml``-based
+projects, like `uv <https://docs.astral.sh/uv/>`_ (``uv pip install``).
+Preferably, have a :ref:`virtual environment <venv-def>` activated.
+
+
+.. note::
+
+   This tutorial uses APIs that were added in CPython 3.15.
+   To create an extension that's compatible with earlier versions of CPython,
+   please follow an earlier version of this documentation.
+
+   This tutorial uses C syntax added in C11 and C++20.
+   If your extension needs to be compatible with earlier standards,
+   please follow tutorials in documentation for Python 3.14 or below.
+
+
+What we'll do
+=============
+
+Let's create an extension module called ``spam`` [#why-spam]_,
+which will include a Python interface to the C
+standard library function :c:func:`system`.
+This function is defined in ``stdlib.h``.
+It takes a C string as argument, runs the argument as a system
+command, and returns a result value as an integer.
+A manual page for :c:func:`system` might summarize it this way::
+
+   #include <stdlib.h>
+   int system(const char *command);
+
+Note that like many functions in the C standard library,
+this function is already exposed in Python.
+In production, use :py:func:`os.system` or :py:func:`subprocess.run`
+rather than the module you'll write here.
+
+We want this function to be callable from Python as follows:
+
+.. code-block:: pycon
+
+   >>> import spam
+   >>> status = spam.system("whoami")
+   User Name
+   >>> status
+   0
+
+.. note::
+
+   The system command ``whoami`` prints out your username.
+   It's useful in tutorials like this one because it has the same name on
+   both Unix and Windows.
+
+
+Start with the headers
+======================
+
+Begin by creating a directory for this tutorial, and switching to it
+on the command line.
+Then, create a file named :file:`spammodule.c` in your directory.
+[#why-spammodule]_
+
+In this file, we'll include two headers: :file:`Python.h` to pull in
+all declarations of the Python C API, and :file:`stdlib.h` for the
+:c:func:`system` function. [#stdlib-h]_
+
+Add the following lines to :file:`spammodule.c`:
+
+.. literalinclude:: ../includes/capi-extension/spammodule-01.c
+   :start-at: <Python.h>
+   :end-at: <stdlib.h>
+
+Be sure to put :file:`stdlib.h`, and any other standard library includes,
+*after* :file:`Python.h`.
+On some systems, Python may define some pre-processor definitions
+that affect the standard headers.
+
+
+Running your build tool
+=======================
+
+With only the includes in place, your extension won't do anything.
+Still, it's a good time to compile it and try to import it.
+This will ensure that your build tool works, so that you can make
+and test incremental changes as you follow the rest of the text.
+
+CPython itself does not come with a tool to build extension modules;
+it is recommended to use a third-party project for this.
+In this tutorial, we'll use `meson-python`_.
+(If you want to use another one, see :ref:`first-extension-other-tools`.)
+
+.. at the time of writing, meson-python has the least overhead for a
+   simple extension using PyModExport.
+   Change this if another tool makes things easier.
+
+``meson-python`` requires defining a "project" using two extra files.
+
+First, add ``pyproject.toml`` with these contents:
+
+.. code-block:: toml
+
+   [build-system]
+   build-backend = 'mesonpy'
+   requires = ['meson-python']
+
+   [project]
+   # Placeholder project information
+   # (change this before distributing the module)
+   name = 'sampleproject'
+   version = '0'
+
+Then, create ``meson.build`` containing the following:
+
+.. code-block:: meson
+
+   project('sampleproject', 'c')
+
+   py = import('python').find_installation(pure: false)
+
+   py.extension_module(
+      'spam',          # name of the importable Python module
+      'spammodule.c',  # the C source file
+      install: true,
+   )
+
+.. note::
+
+   See the `meson-python documentation <meson-python_>`_ for details on
+   configuration.
+
+Now, build install the *project in the current directory* (``.``) via ``pip``:
+
+.. code-block:: sh
+
+   python -m pip -v install .
+
+The ``-v`` (``--verbose``) option causes ``pip`` to show the output from
+the compiler, which is often useful during development.
+
+.. tip::
+
+   If you don't have ``pip`` installed, run ``python -m ensurepip``,
+   preferably in a :ref:`virtual environment <venv-def>`.
+   (Or, if you prefer another tool that can build and install
+   ``pyproject.toml``-based projects, use that.)
+
+.. _meson-python: https://mesonbuild.com/meson-python/
+.. _virtual environment: https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/#create-and-use-virtual-environments
+
+Note that you will need to run this command again every time you change your
+extension.
+Unlike Python, C has an explicit compilation step.
+
+When your extension is compiled and installed, start Python and try to
+import it.
+This should fail with the following exception:
+
+.. code-block:: pycon
+
+   >>> import spam
+   Traceback (most recent call last):
+      ...
+   ImportError: dynamic module does not define module export function (PyModExport_spam or PyInit_spam)
+
+
+Module export hook
+==================
+
+The exception you got when you tried to import the module told you that Python
+is looking for a "module export function", also known as a
+:ref:`module export hook <extension-export-hook>`.
+Let's define one.
+
+First, add a prototype below the ``#include`` lines:
+
+.. literalinclude:: ../includes/capi-extension/spammodule-01.c
+   :start-after: /// Export hook prototype
+   :end-before: ///
+
+.. tip::
+   The prototype is not strictly necessary, but some modern compilers emit
+   warnings without it.
+   It's generally better to add the prototype than to disable the warning.
+
+The :c:macro:`PyMODEXPORT_FUNC` macro declares the function's
+return type, and adds any special linkage declarations needed
+to make the function visible and usable when CPython loads it.
+
+After the prototype, add the function itself.
+For now, make it return ``NULL``:
+
+.. code-block:: c
+
+   PyMODEXPORT_FUNC
+   PyModExport_spam(void)
+   {
+      return NULL;
+   }
+
+Compile and load the module again.
+You should get a different error this time.
+
+.. code-block:: pycon
+
+   >>> import spam
+   Traceback (most recent call last):
+      ...
+   SystemError: module export hook for module 'spam' failed without setting an exception
+
+Simply returning ``NULL`` is *not* correct behavior for an export hook,
+and CPython complains about it.
+That's good -- it means that CPython found the function!
+Let's now make it do something useful.
+
+
+The slot table
+==============
+
+Rather than ``NULL``, the export hook should return the information needed to
+create a module.
+Let's start with the basics: the name and docstring.
+
+The information should be defined in an array of
+:c:type:`PySlot` entries, which are essentially key-value pairs.
+Define this array just before your export hook:
+
+.. code-block:: c
+
+   PyABIInfo_VAR(abi_info);
+
+   static PySlot spam_slots[] = {
+      PySlot_STATIC_DATA(Py_mod_abi, &abi_info),
+      PySlot_STATIC_DATA(Py_mod_name, "spam"),
+      PySlot_STATIC_DATA(Py_mod_doc, "A wonderful module with an example function"),
+      PySlot_END
+   };
+
+The :c:macro:`PySlot_STATIC_DATA` macro is used when the slot value
+(here: ``&abi_info``, ``"spam"``, and the docstring) is a pointer to constant,
+statically allocated data.
+
+The ``PyABIInfo_VAR(abi_info);`` macro and the :c:data:`Py_mod_abi` slot
+are a bit of boilerplate that helps prevent extensions compiled for
+a different version of Python from crashing the interpreter.
+
+For both :c:data:`Py_mod_name` and :c:data:`Py_mod_doc`, the values are C
+strings -- that is, NUL-terminated, UTF-8 encoded byte arrays.
+
+Note ``PySlot_END`` sentinel entry at the end.
+This marks the end of the array.
+If you forget it, you'll trigger undefined behavior.
+
+The array is defined as ``static`` -- that is, not visible outside this ``.c`` file.
+This will be a common theme.
+CPython only needs to access the export hook; all global variables
+and all other functions should generally be ``static``, so that they don't
+clash with other extensions.
+
+Return this array from your export hook instead of ``NULL``:
+
+.. code-block:: c
+   :emphasize-lines: 4
+
+   PyMODEXPORT_FUNC
+   PyModExport_spam(void)
+   {
+      return spam_slots;
+   }
+
+Now, recompile and try it out:
+
+.. code-block:: pycon
+
+   >>> import spam
+   >>> print(spam)
+   <module 'spam' from '/home/encukou/dev/cpython/spam.so'>
+
+You have an extension module!
+Try ``help(spam)`` to see the docstring.
+
+The next step will be adding a function.
+
+
+.. _backtoexample:
+
+Exposing a function
+===================
+
+To expose the :c:func:`system` C function directly to Python,
+we'll need to write a layer of glue code to convert arguments from Python
+objects to C values, and the C return value back to Python.
+
+One of the simplest ways to write glue code is a ":c:data:`METH_O`" function,
+which takes two Python objects and returns one.
+All Python objects -- regardless of the Python type -- are represented in C
+as pointers to the :c:type:`PyObject` structure.
+
+Add such a function above the slots array::
+
+   static PyObject *
+   spam_system(PyObject *self, PyObject *arg)
+   {
+      Py_RETURN_NONE;
+   }
+
+For now, we ignore the arguments, and use the :c:macro:`Py_RETURN_NONE`
+macro, which expands to a ``return`` statement that properly returns
+a Python :py:data:`None` object.
+
+Recompile your extension to make sure you don't have syntax errors.
+We haven't yet added ``spam_system`` to the module, so you might get a
+warning that ``spam_system`` is unused.
+
+.. _methodtable:
+
+Method definitions
+------------------
+
+To expose the C function to Python, you will need to provide several pieces of
+information in a structure called
+:c:type:`PyMethodDef` [#why-pymethoddef]_:
+
+* ``ml_name``: the name of the Python function;
+* ``ml_doc``: a docstring;
+* ``ml_meth``: the C function to be called; and
+* ``ml_flags``: a set of flags describing details like how Python arguments are
+  passed to the C function.
+  We'll use :c:data:`METH_O` here -- the flag that matches our
+  ``spam_system`` function's signature.
+
+Because modules typically create several functions, these definitions
+need to be collected in an array, with a zero-filled sentinel at the end.
+Add this array just below the ``spam_system`` function:
+
+.. literalinclude:: ../includes/capi-extension/spammodule-01.c
+   :start-after: /// Module method table
+   :end-before: ///
+
+As with module slots, a zero-filled sentinel marks the end of the array.
+
+Next, we'll add the method to the module.
+Add a :c:data:`Py_mod_methods` slot to your :c:type:`PyMethodDef` array:
+
+.. literalinclude:: ../includes/capi-extension/spammodule-01.c
+   :start-after: /// Module slot table
+   :end-before: ///
+   :emphasize-lines: 5
+
+Recompile your extension again, and test it.
+Be sure to restart the Python interpreter, so that ``import spam`` picks
+up the new version of the module.
+
+You should now be able to call the function:
+
+.. code-block:: pycon
+
+   >>> import spam
+   >>> print(spam.system)
+   <built-in function system>
+   >>> print(spam.system('whoami'))
+   None
+
+Note that our ``spam.system`` does not yet run the ``whoami`` command;
+it only returns ``None``.
+
+Check that the function accepts exactly one argument, as specified by
+the :c:data:`METH_O` flag:
+
+.. code-block:: pycon
+
+   >>> print(spam.system('too', 'many', 'arguments'))
+   Traceback (most recent call last):
+      ...
+   TypeError: spam.system() takes exactly one argument (3 given)
+
+
+Returning an integer
+====================
+
+Now, let's take a look at the return value.
+Instead of ``None``, we'll want ``spam.system`` to return a number -- that is,
+a Python :py:type:`int` object.
+Eventually this will be the exit code of a system command,
+but let's start with a fixed value, say, ``3``.
+
+The Python C API provides a function to create a Python :py:type:`int` object
+from a C ``int`` value: :c:func:`PyLong_FromLong`. [#why-pylongfromlong]_
+
+To call it, replace the ``Py_RETURN_NONE`` with the following 3 lines:
+
+.. this could be a one-liner, but we want to show the data types here
+
+.. code-block:: c
+   :emphasize-lines: 4-6
+
+   static PyObject *
+   spam_system(PyObject *self, PyObject *arg)
+   {
+      int status = 3;
+      PyObject *result = PyLong_FromLong(status);
+      return result;
+   }
+
+
+Recompile, restart the Python interpreter again,
+and check that the function now returns 3:
+
+.. code-block:: pycon
+
+   >>> import spam
+   >>> spam.system('whoami')
+   3
+
+
+Accepting a string
+==================
+
+Finally, let's handle the function argument.
+
+Our C function, :c:func:`!spam_system`, takes two arguments.
+The first one, ``PyObject *self``, will be set to the ``spam`` module
+object.
+This isn't useful in our case, so we'll ignore it.
+
+The other one, ``PyObject *arg``, will be set to the object that the user
+passed from Python.
+We expect that it should be a Python string.
+In order to use the information in it, we will need
+to convert it to a C value -- in this case, a C string (``const char *``).
+
+There's a slight type mismatch here: Python's :py:class:`str` objects store
+Unicode text, but C strings are arrays of bytes.
+So, we'll need to *encode* the data, and we'll use the UTF-8 encoding for it.
+(UTF-8 might not always be correct for system commands, but it's what
+:py:meth:`str.encode` uses by default,
+and the C API has special support for it.)
+
+The function to encode a Python string into a UTF-8 buffer is named
+:c:func:`PyUnicode_AsUTF8AndSize` [#why-pyunicodeasutf8]_.
+Call it like this:
+
+.. code-block:: c
+   :emphasize-lines: 4
+
+   static PyObject *
+   spam_system(PyObject *self, PyObject *arg)
+   {
+      const char *command = PyUnicode_AsUTF8AndSize(arg, NULL);
+      int status = 3;
+      PyObject *result = PyLong_FromLong(status);
+      return result;
+   }
+
+If :c:func:`PyUnicode_AsUTF8AndSize` is successful, *command* will point to the
+resulting C string -- a zero-terminated array of bytes [#embedded-nul]_.
+This buffer is managed by the *arg* object, which means we don't need to free
+it, but we must follow some rules:
+
+* We should only use the buffer inside the ``spam_system`` function.
+  After ``spam_system`` returns, *arg* and the buffer it manages might be
+  garbage-collected.
+* We must not modify it. This is why we use ``const``.
+
+If :c:func:`PyUnicode_AsUTF8AndSize` was *not* successful, it returns a ``NULL``
+pointer.
+When calling *any* Python C API, we always need to handle such error cases.
+The way to do this in general is left for later chapters of this documentation.
+For now, be assured that we are already handling errors from
+:c:func:`PyLong_FromLong` correctly.
+
+For the :c:func:`PyUnicode_AsUTF8AndSize` call, the correct way to handle
+errors is returning ``NULL`` from ``spam_system``.
+Add an ``if`` block for this:
+
+
+.. code-block:: c
+   :emphasize-lines: 5-7
+
+   static PyObject *
+   spam_system(PyObject *self, PyObject *arg)
+   {
+      const char *command = PyUnicode_AsUTF8AndSize(arg);
+      if (command == NULL) {
+         return NULL;
+      }
+      int status = 3;
+      PyObject *result = PyLong_FromLong(status);
+      return result;
+   }
+
+To test that error handling works, compile again, restart Python so that
+``import spam`` picks up the new version of your module, and try passing
+a non-string value to your function:
+
+.. code-block:: pycon
+
+   >>> import spam
+   >>> spam.system(3)
+   Traceback (most recent call last):
+      ...
+   TypeError: bad argument type for built-in operation
+
+Now, all that is left is calling the C library function :c:func:`system` with
+the ``char *`` buffer, and using its result instead of the ``3``:
+
+.. code-block:: c
+   :emphasize-lines: 8
+
+   static PyObject *
+   spam_system(PyObject *self, PyObject *arg)
+   {
+      const char *command = PyUnicode_AsUTF8AndSize(arg);
+      if (command == NULL) {
+         return NULL;
+      }
+      int status = system(command);
+      PyObject *result = PyLong_FromLong(status);
+      return result;
+   }
+
+Compile your module, restart Python, and test.
+This time, you should see your username -- the output of the ``whoami``
+system command:
+
+.. code-block:: pycon
+
+   >>> import spam
+   >>> result = spam.system('whoami')
+   User Name
+   >>> result
+   0
+
+You can also test with other commands, like ``ls``, ``dir``, or one
+that doesn't exist:
+
+.. code-block:: pycon
+
+   >>> import spam
+   >>> result = spam.system('nonexistent-command')
+   sh: line 1: nonexistent-command: command not found
+   >>> result
+   32512
+
+
+The result
+==========
+
+
+Congratulations!
+You have written a complete Python C API extension module,
+and completed this tutorial!
+
+Here is the entire source file, for your convenience:
+

+
+Appendix: Other build tools
+===========================
+
+You should be able to follow this tutorial -- except the
+*Running your build tool* section itself -- with a build tool other
+than ``meson-python``.
+
+The Python Packaging User Guide has a `list of recommended tools <https://packaging.python.org/en/latest/guides/tool-recommendations/#build-backends-for-extension-modules>`_;
+be sure to choose one for the C language.
+
+
+Workaround for missing PyInit function
+--------------------------------------
+
+If your build tool output complains about missing ``PyInit_spam``,
+add the following function to your module for now:
+
+.. code-block:: c
+
+   // A workaround
+   void *PyInit_spam(void) { return NULL; }
+
+This is a shim for an old-style :ref:`initialization function <extension-export-hook>`,
+which was required in extension modules for CPython 3.14 and below.
+Current CPython does not need it, but some build tools may still assume that
+all extension modules need to define it.
+
+If you use this workaround, you will get the exception
+``SystemError: initialization of spam failed without raising an exception``
+instead of
+``ImportError: dynamic module does not define module export function``.
+
+
+Compiling directly
+------------------
+
+Using a third-party build tool is heavily recommended,
+as it will take care of various details of your platform and Python
+installation, of naming the resulting extension, and, later, of distributing
+your work.
+
+If you are building an extension for as *specific* system, or for yourself
+only, you might instead want to run your compiler directly.
+The way to do this is system-specific; be prepared for issues you will need
+to solve yourself.
+
+Linux
+^^^^^
+
+On Linux, the Python development package may include a ``python3-config``
+command that prints out the required compiler flags.
+If you use it, check that it corresponds to the CPython interpreter you'll use
+to load the module.
+Then, start with the following command:
+
+.. code-block:: sh
+
+   gcc --shared $(python3-config --cflags --ldflags) spammodule.c -o spam.so
+
+This should generate a ``spam.so`` file that you need to put in a directory
+on :py:attr:`sys.path`.
+
+
+.. rubric:: Footnotes
+
+.. [#why-spam] ``spam`` is the favorite food of Monty Python fans...
+.. [#why-spammodule] The source file name is entirely up to you,
+   though some tools can be picky about the ``.c`` extension.
+   This tutorial uses the traditional ``*module.c`` suffix.
+   Some people would just use :file:`spam.c` to implement a module
+   named ``spam``,
+   projects where Python isn't the primary language might use ``py_spam.c``,
+   and so on.
+.. [#stdlib-h] Including :file:`stdlib.h` is technically not necessary,
+   since :file:`Python.h` includes it and
+   :ref:`several other standard headers <capi-system-includes>` for its own use
+   or for backwards compatibility.
+   However, it is good practice to explicitly include what you need.
+.. [#why-pymethoddef] The :c:type:`!PyMethodDef` structure is also used
+   to create methods of classes, so there's no separate
+   ":c:type:`!PyFunctionDef`".
+.. [#why-pylongfromlong] The name :c:func:`PyLong_FromLong`
+   might not seem obvious.
+   ``PyLong`` refers to a the Python :py:class:`int`, which was originally
+   called ``long``; the ``FromLong`` refers to the C ``long`` (or ``long int``)
+   type.
+.. [#why-pyunicodeasutf8] Here, ``PyUnicode`` refers to the original name of
+   the Python :py:class:`str` class: ``unicode``.
+
+   The ``AndSize`` part of the name refers to the fact that this function can
+   also retrieve the size of the buffer, using an output argument.
+   We don't need this, so we set the second argument to NULL.
+.. [#embedded-nul] We're ignoring the fact that Python strings can also
+   contain NUL bytes, which terminate a C string.
+   In other words, our function will treat ``spam.system("foo\0bar")`` as
+   ``spam.system("foo")``.
+   This possibility can lead to security issues, so the real ``os.system``
+   function size checks for this case and raises an error.

+******************************************************
+Migrating to Stable ABI for free threading (``abi3t``)
+******************************************************
+
+Starting with the 3.15 release, CPython supports a variant of the Stable ABI
+that supports :term:`free-threaded <free threading>` Python:
+Stable ABI for Free-Threaded Builds, or ``abi3t`` for short.
+This document describes how to adapt C API extensions to support free threading.
+
+Why do this
+===========
+
+The typical reason to use Stable ABI is to reduce the number of artifacts that
+you need to build and distribute for each version of your library.
+
+Without the Stable ABI, you must build a separate shared library, and typically
+a *wheel* distribution, for each feature version of CPython you wish
+to support.
+For example, each tag in the following table represents a separate
+library/wheel:
+
++-----------------+-----------------------+------------------------+
+| CPython version | Non-free-threaded     | Free-threaded          |
++=================+=======================+========================+
+| 3.12            | ``cpython-312``       | ---                    |
++-----------------+-----------------------+------------------------+
+| 3.13            | ``cpython-313``       | ``cpython-313t``       |
++-----------------+-----------------------+------------------------+
+| 3.14            | ``cpython-314``       | ``cpython-314t``       |
++-----------------+-----------------------+------------------------+
+| 3.15            | ``cpython-315``       | ``cpython-315t``       |
++-----------------+-----------------------+------------------------+
+| 3.16            | ``cpython-316``       | ``cpython-316t``       |
++-----------------+-----------------------+------------------------+
+| Later versions  | :samp:`cpython-3{XX}` | :samp:`cpython-3{XX}t` |
++-----------------+-----------------------+------------------------+
+
+That's a lot of builds, especially when multiplied by the number
+of supported platforms.
+
+With the Stable ABI (``abi3``, introduced in CPython 3.2), a single extension
+(per platform) can cover all *non-free-threaded* builds of CPython:
+
++-----------------+-------------------+------------------------+
+| CPython version | Non-free-threaded | Free-threaded          |
++=================+===================+========================+
+| 3.12            | ``abi3``          | ---                    |
++-----------------+                   +------------------------+
+| 3.13            |                   | ``cpython-313t``       |
++-----------------+                   +------------------------+
+| 3.14            |                   | ``cpython-314t``       |
++-----------------+                   +------------------------+
+| 3.15            |                   | ``cpython-315t``       |
++-----------------+                   +------------------------+
+| 3.16            |                   | ``cpython-316t``       |
++-----------------+                   +------------------------+
+| Later versions  |                   | :samp:`cpython-3{XX}t` |
++-----------------+-------------------+------------------------+
+
+The Stable ABI for free-threaded builds (``abi3t``), introduced in
+CPython 3.15, does the same for free-threaded builds.
+And it's compatible with non-free-threaded ones as well:
+
++-----------------+-------------------+------------------+
+| CPython version | Non-free-threaded | Free-threaded    |
++=================+===================+==================+
+| 3.12            | ``abi3`` *        | ---              |
++-----------------+                   +------------------+
+| 3.13            |                   | ``cpython-313t`` |
++-----------------+                   +------------------+
+| 3.14            |                   | ``cpython-314t`` |
++-----------------+-------------------+------------------+
+| 3.15            | ``abi3t``                            |
++-----------------+                                      +

++-----------------+                                      +
+| Later versions  |                                      |
++-----------------+-------------------+------------------+
+
+\* (As above, the ``abi3`` extension is compatible with all non-free-threaded
+builds; even the 3.15+ ones that this table "attributes" to ``abi3t``.)
+
+Why *not* do this
+-----------------
+
+There are two main downsides to Stable ABI.
+
+First, you extension may become slower, since Stable ABI prioritizes
+compatibility over performance.
+The difference is usually not noticeable, and often can be mitigated by
+using the same source to build both a Stable ABI build and a few
+version-specific ones for "tier 1" CPython versions.
+
+Second, not all of the C API is available.
+Extensions need to be ported to build for Stable ABI, which may be difficult
+or, in rare cases, impossible.
+
+Specifically, ``abi3t`` requires APIs added in CPython 3.15.
+If you want to build your extension for older versions of CPython from the
+same source, you have two main options:
+
+- Use preprocessor conditionals.
+
+  When following this guide, use ``#ifdef Py_TARGET_ABI3T`` blocks whenever
+  you are told to do a change that breaks the build on CPython versions you
+  care about. Keep the pre-existing code in ``#else`` blocks.
+
+  For hand-written C extensions, this approach is reasonable down to
+  CPython 3.12, due to additions introduced in :pep:`697`.
+  Keeping compatibility with 3.11 and below may be worth it for code
+  generators (for example, Cython).
+
+- Do not port to ``abi3t``, and continue building separate extensions for
+  each version of CPython, until you can drop support for the older versions.
+
+  This is a valid approach. Not all extensions need to switch to ``abi3t``
+  right now.
+
+
+Prerequisites
+=============
+
+This guide assumes that you have an extension written directly in C (or C++),
+which you want to port to ``abi3t``.
+
+If your extenstion uses a code generator (like Cython) or language binding
+(like PyO3), it's best to wait until that tool has support for ``abi3t``.
+If you maintain such a tool, you might be able to adapt the instructions
+here for your tool.
+
+Non-free-threaded Stable ABI
+----------------------------
+
+Your extension should support the Stable ABI (``abi3t``).
+If not, either port it first, or follow this guide but be prepared to fix
+issues it does not mention.
+
+Free-threading support
+----------------------
+
+While it's technically not a hard prerequisite, you will most likely want to
+prepare your extension for free threading before you port it to ``abi3t``.
+See :ref:`freethreading-extensions-howto` for instructions.
+
+.. seealso::
+
+   `Porting Extension Modules to Support Free-Threading
+   <https://py-free-threading.github.io/porting/>`__:
+   A community-maintained porting guide for extension authors.
+
+Isolating extension modules
+---------------------------
+
+Your module should use :ref:`multi-phase initialization <multi-phase-initialization>`,
+and it should either be isolated or limit itself to be loaded at most once
+per process.
+If it is not your case, follow :ref:`isolating-extensions-howto` first.
+(See the :ref:`opt-out section <isolating-extensions-optout>` for a shortcut.)
+
+Avoiding variable-sized types
+-----------------------------
+
+If your extension defines variable-sized types (using :c:macro:`Py_tp_itemsize`
+or :c:member:`PyTypeObject.tp_itemsize`), it cannot be ported to
+``abi3t`` 3.15.
+
+
+Setting up the build
+====================
+
+If you use a build tool (such as setuptools, meson-python, scikit-build-core),
+search its documentation for a way to select ``abi3t``.
+At the time of writing, not all of them have this; but if your tool does,
+use it.
+You may want to verify that it set the right flag by temporarily adding the
+following just after ``#include <Python.h>``::
+
+   #if Py_TARGET_ABI3T+0 <= 0x30f0000
+   #error "abi3t define is not set!"
+   #endif
+
+This should result in a different error than "``abt3t`` define is not set".
+
+.. note::
+
+   If your build tool doesn't support ``abi3t`` yet, set the following macro
+   before including ``Python.h``::
+
+      #define Py_TARGET_ABI3T 0x30f0000
+
+   or specify it as a compiler flag, for example::
+
+      -DPy_TARGET_ABI3T=0x30f0000
+
+   Once your extension builds with this setting, it will be compatible with
+   CPython 3.15 and above.
+
+   If you set this macro manually, you will later need to name and tag the
+   resulting extension manually as well.
+   This is covered in :ref:`abi3t-migration-tagging` below.
+
+This guide will ask you to make a series of changes.
+After each one, verify that your extension still builds in the original
+(non-``abi3t``) configuration, and ideally run tests on all Python
+versions you support.
+This will ensure that nothing breaks as you are porting.
+
+
+.. _abi3t-howto-modexport:
+
+Module export hook
+==================
+
+Unless you've done this step already, your extension module defines a
+:ref:`module initialization function <extension-pyinit>`
+named :samp:`PyInit_{<module_name>}`.
+You will need to port it to a :ref:`module export hook <extension-export-hook>`,
+:samp:`PyModExport_{<module name>}`, a feature added in CPython 3.15 in
+:pep:`793`.
+
+Your existing init function should look like this (with your own names
+for ``<modname>`` and ``<moddef>``):
+
+.. code-block::
+   :class: bad
+
+   PyMODINIT_FUNC
+   PyInit_<modname>(void)
+   {
+       return PyModuleDef_Init(&<moddef>);
+   }
+
+If there is some code before the ``return``, move it to
+a :c:macro:`Py_mod_create` or :c:macro:`Py_mod_exec` slot function.
+See the :ref:`PyInit documentation <extension-pyinit>` for related information.
+
+The function references a ``PyModuleDef`` object (``<moddef>`` in the code
+above).
+Its definition should be similar to the following, with different values
+and perhaps some fields unnnamed or left out:
+
+.. code-block::
+   :class: bad
+
+   static PyModuleDef <moddef> = {
+       PyModuleDef_HEAD_INIT,
+       .m_name = "my_module",
+       .m_doc = "my docstring",
+       .m_size = sizeof(my_state_struct),
+       .m_methods = my_methods,
+       .m_slots = my_slots,
+       .m_traverse = my_traverse,
+       .m_clear = my_clear,
+       .m_free = my_free,
+   };
+
+Remove this definition and the ``PyInit`` function (or put them in
+an ``#ifndef Py_TARGET_ABI3T`` block, to retain backwards compatibility),
+and replace them with the following:
+
+.. code-block::
+   :class: good
+
+   PyABIInfo_VAR(abi_info);
+
+   static PySlot my_slot_array[] = {
+       PySlot_STATIC_DATA(Py_mod_abi, &abi_info),
+       PySlot_STATIC_DATA(Py_mod_name, "my_module"),
+       PySlot_STATIC_DATA(Py_mod_doc, "my docstring"),
+       PySlot_SIZE(Py_mod_state_size, sizeof(my_state_struct)),
+       PySlot_STATIC_DATA(Py_mod_methods, my_methods),
+       PySlot_STATIC_DATA(Py_mod_slots, my_slots),
+       PySlot_FUNC(Py_mod_state_traverse, my_traverse),
+       PySlot_FUNC(Py_mod_state_clear, my_clear),
+       PySlot_FUNC(Py_mod_state_free, my_free),
+       PySlot_END
+   };
+
+   PyMODEXPORT_FUNC
+   PyModExport_<modname>(void)
+   {
+       return my_slot_array;
+   }
+
+Leave out any fields that were missing (except the new :c:macro:`Py_mod_abi`),
+and substitute your own values.
+
+See the :c:type:`PySlot` and :c:ref:`export hook <extension-export-hook>`
+documentation for details on this API.
+
+As in the example, your ``PyModExport_`` function should *only* return a
+pointer to static data.
+If you cannot avoid additional code, refer to the
+:ref:`caveats in PyModExport documentation <pymodexport-api-caveats>`.
+
+
+Existing slots
+--------------
+
+If you have a ``Py_mod_slots`` slot, check the array it refers to.
+It should be a :c:type:`PyModuleDef_Slot` array like the following:
+
+.. code-block::
+   :class: bad
+
+   static PyObject *create_module(PyObject *spec, PyModuleDef *def) { ... }
+   static int my_first_module_exec(PyObject *module) { ... }
+   static int my_second_module_exec(PyObject *module) { ... }
+
+   static PyModuleDef_Slot my_slots[] = {
+      {Py_mod_gil, Py_MOD_GIL_NOT_USED},
+      {Py_mod_multiple_interpreters, Py_MOD_PER_INTERPRETER_GIL_SUPPORTED},
+      {Py_mod_create, my_module_create},
+      {Py_mod_exec, my_first_module_exec},
+      {Py_mod_exec, my_second_module_exec},
+      {0, NULL}
+   };
+
+``py_mod_create``
+.................
+
+
+If you have a :c:macro:`Py_mod_create` entry, make sure the function can be
+called with ``NULL`` as its second argument (instead of the
+:c:type:`PyModuleDef`, which you are removing).
+Often, this argument isn't used at all; you can check by renaming it:
+
+.. code-block::
+   :class: good
+
+   static PyObject *create_module(PyObject *spec, PyModuleDef *_unused) { ... }
+
+If the argument is used, find a different way to pass in the data.
+Commonly, the information is static and you can refer to it directly.
+(If you're reusing a single function for several different modules, consider
+defining several functions instead.)
+
+
+Multiple ``py_mod_exec``
+........................
+
+If you have *more than one* :c:macro:`Py_mod_exec` entry, consolidate them:
+create a new function that calls the others, and replace existing slots
+with it.
+
+.. code-block::
+   :class: good
+
+   static int my_module_exec(PyObject *module) {
+      if (my_first_module_exec(module) < 0) return -1;
+      if (my_second_module_exec(module) < 0) return -1;
+   }
+
+   static PyModuleDef_Slot my_slots[] = {
+      ...
+      /* (remove other Py_mod_exec slots) */
+      ...
+      {Py_mod_exec, my_module_exec},
+      {0, NULL}
+   };
+
+If the functions aren't used elsewhere, you can combine their bodies instead.
+
+
+Merging slot arrays
+...................
+
+Optionally, when you break compatibility with Python 3.14, you may clean up
+the code by moving slots into the :c:type:`PySlot` array, and converting the
+definitions to :c:macro:`PySlot_DATA` and :c:macro:`PySlot_FUNC`:
+
+.. code-block::
+   :class: good
+
+   static PySlot my_slot_array[] = {
+       ...
+       PySlot_DATA(Py_mod_gil, Py_MOD_GIL_NOT_USED),
+       PySlot_DATA(Py_mod_multiple_interpreters,
+            Py_MOD_PER_INTERPRETER_GIL_SUPPORTED)
+       PySlot_FUNC(Py_mod_create, my_module_create),
+       PySlot_FUNC(Py_mod_exec, my_module_exec),
+       PySlot_END
+   };
+
+If you do this, delete the original :c:type:`PyModuleDef_Slot` array and
+its ``Py_mod_slots`` entry.
+
+
+Associated ``PyModuleDef``
+--------------------------
+
+Since the new API does not use a :c:type:`!PyModuleDef` structure, a definition
+will not be associated with the resulting module.
+This changes the behavior of the following functions:
+
+- :c:func:`PyModule_GetDef`
+- :c:func:`PyType_GetModuleByDef`
+
+Check your code for these.
+If you do not use them, you can skip this section.
+
+These functions are typically used for two purposes:
+
+1. To get the definition the module was created with.
+   This is no longer possible using the new API.
+   Modules no longer keep a reference to the definition, so you will need to
+   figure out a different way to pass the relevant data around.
+
+.. _abi3t-migration-module-token:
+
+2. To check if a given module object is “yours”.
+   This use case is now served by :ref:`module tokens <ext-module-token>` --
+   opaque pointers that identify a module.
+   To use a token, declare (or reuse) a unique static variable, for example:
+
+   .. code-block::
+      :class: good
+
+      static char my_token;
+
+   and add a pointer to it in a new entry to your module's ``PySlot`` array:
+
+   .. code-block::
+      :class: good
+      :emphasize-lines: 3
+
+      static PySlot my_slot_array[] = {
+         ...
+         PySlot_STATIC_DATA(Py_mod_token, &my_token),
+         PySlot_END
+      }
+
+   Then, switch from :c:func:`PyModule_GetDef` calls such as:
+
+   .. code-block::
+      :class: bad
+
+      PyModuleDef *def = PyModule_GetDef(module);
+
+   to :c:func:`PyModule_GetToken` (which uses an output argument and may fail
+   with an exception):
+
+   .. code-block::
+      :class: good
+
+      void *token;
+      if (PyModule_GetToken(module, &token) < 0) {
+          /* handle error */
+      }
+
+   and from :c:func:`PyType_GetModuleByDef` calls such as:
+
+   .. code-block::
+      :class: bad
+
+      PyObject *module = PyType_GetModuleByDef(type, my_def);
+      /* handle error; use module */
+
+   to :c:func:`PyType_GetModuleByToken` (which returns a strong reference):
+
+   .. code-block::
+      :class: good
+
+      PyObject *module = PyType_GetModuleByToken(type, my_token);
+      /* handle error; use module */
+      Py_XDECREF(module);
+
+``PyObject`` opaqueness
+=======================
+
+The :c:type:`PyObject` and :c:type:`PyVarObject` structures are opaque
+in ``abi3t``.
+
+Accessing their members is prohibited.
+If you do this, switch to getter/setter functions mentioned in
+their documentation:
+
+- :c:member:`PyObject.ob_type`
+- :c:member:`PyObject.ob_refcnt`
+- :c:member:`PyVarObject.ob_size`
+
+Also, the *size* of the :c:type:`PyObject` structures is
+unknown to the compiler.
+It can -- and *does* -- change between different CPython builds.
+
+.. note::
+
+   While the size is available at runtime (for example as
+   ``sys.getsizeof(object())`` in Python code), you should resist the
+   temptation to calculate pointer offsets from it.
+   The object memory layout is subject to change in future
+   ``abi3t`` implementations.
+
+
+Custom type definitions
+-----------------------
+
+Since :c:type:`!PyObject` is opaque, the traditional way of defining
+custom types no longer works:
+
+.. code-block::
+   :class: bad
+
+   typedef struct {
+      PyObject_HEAD  // expands to `PyObject ob_base;` which has unknown size
+
+      int my_data;
+   } CustomObject;
+
+   static PyType_Spec CustomType_spec = {
+      ...
+      .basicsize = sizeof(CustomObject),
+      ...
+   };
+
+Most likely, all your class definitions, *and* all code that accesses
+your classes' data, will need to be rewritten.
+This will probably be the biggest change you need to support ``abi3t``.
+
+For each such type, instead of defining a ``struct`` for the entire instance,
+define one with only the “additional” fields -- ones specific to your class,
+not its superclasses:
+
+.. code-block::
+   :class: good
+
+   typedef struct {
+      int my_data;
+   } CustomObjectData;
+
+Change the name.
+Almost all code that uses the struct will need to change
+(notably, pointers to the new structure cannot be cast to/from ``PyObject*``),
+and changing the name will highlight the usages as compiler errors.
+(If you use ``typeof``, C++ ``auto``, or similar ways to avoid
+typing the type name, this won't work. Be extra careful, and consider running
+tools to detect undefined behavior.)
+
+Then, to create the class, use *negative* ``basicsize`` to indicate
+“extra” storage space rather than *total* instance size:
+
+.. code-block::
+   :class: good
+
+   static PyType_Spec CustomType_spec = {
+      ...
+      .basicsize = -sizeof(CustomObjectData), /* note the minus sign */
+      ...
+   };
+
+If you use :c:macro:`Py_tp_members`, set the :c:macro:`Py_RELATIVE_OFFSET`
+flag on each member and specify the :c:member:`~PyMemberDef.offset`
+relative to your new struct.
+
+
+Custom type data access
+-----------------------
+
+Then comes the hard part: in all code that needs to access this struct,
+you will need an additional :c:func:`PyObject_GetTypeData` call to
+retrieve a ``CustomObjectData *`` pointer from ``PyObject *``:
+
+.. code-block::
+   :class: good
+
+   PyObject *obj = ...;
+   CustomObjectData *data = PyObject_GetTypeData(obj, cls);
+
+Note that this call requires the *type object* for your class (``cls``).
+
+If your class is not subclassable (that is, it does not use the
+:c:macro:`Py_TPFLAGS_BASETYPE` flag), ``cls`` will be ``Py_TYPE(obj)``.
+Otherwise, **DO NOT USE** ``Py_TYPE`` with :c:func:`!PyObject_GetTypeData`:
+it might return memory reserved to an unrelated subclass!
+For example, if a user makes a subclass like this:
+
+.. code-block:: python
+
+   class Sub(YourCustomClass):
+      __slots__ = ('a', 'b')
+
+then ``Py_TYPE(obj)`` is ``Sub``, and the underlying memory may
+look like this:
+
+.. code-block:: text
+
+   ╭─ PyObject *obj
+   │              ╭─ the pointer you want
+   │              │                    ╭─ PyObject_GetTypeData(obj, Py_TYPE(obj))

+(Ellipses indicate possible padding.
+Note that this memory layout is not guaranteed: future versions of Python may

+
+There are two main ways to get the right class:
+
+- In instance methods, your implementation may use the :c:type:`PyCMethod`
+  signature (and the :c:macro:`METH_METHOD` bit in
+  :c:member:`PyMethodDef.ml_flags`),
+  and get the class as the ``defining_class`` argument.
+- Otherwise, give your class a unique static token using the
+  :c:macro:`Py_tp_token` slot, and use:
+
+  .. code-block::
+     :class: good
+
+     PyTypeObject cls;
+     if (PyType_GetBaseByToken(Py_TYPE(obj), my_tp_token, &cls) < 0) {
+         /* handle error */
+     }
+     CustomObjectData *data = PyObject_GetTypeData(obj, cls);
+
+  Type tokens work similarly to module tokens covered :ref:`earlier in this
+  guide <abi3t-migration-module-token>`.
+
+
+
+Avoid build-time conditionals
+=============================
+
+Check your code for API that identifies the version of Python used to
+*build* your extension.
+This no longer corresponds to the Python your extension runs on, so code
+that uses this information often needs changing.
+The macros to check for are:
+
+- :c:macro:`PY_VERSION_HEX`, :c:macro:`PY_MAJOR_VERSION`,
+  :c:macro:`PY_MINOR_VERSION`:
+
+  - to get the run-time version, use :c:data:`Py_Version`;
+  - to determine what C API is available, use :c:macro:`Py_TARGET_ABI3T`.
+    This macro is set to the minimum supported version.
+
+- :c:macro:`Py_GIL_DISABLED`: under ``abi3t``, this macro is always defined.
+  Code that works with free-threaded Python *should* also work with
+  the GIL enabled (since the GIL can be enabled at run time),
+  and usually *does* (unless it, for some reason, requires more than one
+  :term:`attached thread state <attached thread state>` at one time).
+
+
+Further code changes
+====================
+
+If you are still left with compiler errors or warnings, find a way to fix them.
+Alas, this guide is limited, and cannot cover all possible code
+changes extensions may need.
+
+If you find a problem that other extension authors might run into,
+consider :ref:`reporting an issue <reporting-documentation-bugs>` (or sending
+a pull request) for this guide.
+
+It is possible your issue cannot be fixed for the current version of ``abi3t``.
+In that case, reporting it may help it get prioritized for the next version
+of CPython.
+
+
+.. _abi3t-migration-tagging:
+
+Tagging and distribution
+========================
+
+If you are using a build tool with ``abi3t`` support, your extension is ready,
+but you might want to check that it was built correctly.
+
+Extensions built with ``abi3t`` should have the following extension:
+
+- On Windows: ``.pyd`` (like any other extension);
+- Linux, macOS, and other systems that use the ``.so`` suffix: ``.abi3t.so``
+  (**not** ``.cpython-315t.so`` or ``.abi3.so``).
+  Note that both free-threaded and non-free-threaded builds will
+  load ``.abi3t.so`` extensions;
+- Other systems: consult your distributor, and perhaps update this guide.
+
+If you distribute the extension as a *wheel*, use the following tags:
+
+* Python tag: :samp:`cp3{XX}`, where *XX* is the minimum Python version
+  the extension is built for.
+  (For example, ``cp315`` if you set ``Py_TARGET_ABI3T`` to ``0x30f0000``.
+  See :ref:`abi3-compiling` for more values.)
+* ABI tag: ``abi3.abi3t``. This is a *compressed tag set* that indicates
+  support for both non-free-threaded and free-threaded builds.
+
+For example, the wheel filename may look like this:
+
+.. code-block:: text
+
+   myproject-1.0-cp315-abi3.abi3t-macosx_11_0_arm64.whl
+
+.. seealso:: `Platform Compatibility Tags <https://packaging.python.org/en/latest/specifications/platform-compatibility-tags/>`__ in the PyPA package distribution metadata.
+
+If the filename or tags are incorrect, fix them.
+
+
+Testing
+=======
+
+Note that when you build an extension compatible with multiple versions of
+CPython, you should always *test* it with each version it supports (for
+example, 3.15, 3.16, and so on).
+Stable ABI only guarantees *ABI* compatibility; there may also be behavior
+changes -- both intentional ones (covered by :pep:`387`) and bugs.
+
+Be sure to run tests on both free-threaded and non-free-threaded builds
+of CPython.
+
+If they pass, congratulations! You have an ``abi3t`` extension.

+
+
+Increased memory usage
+----------------------
+
+The free-threaded build will typically use more memory compared to the default
+build.  There are multiple reasons for this, mostly due to design decisions.
+
+
+All interned strings are immortal
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For modern Python versions (since version 2.3), interning a string (e.g. with
+:func:`sys.intern`) does not cause it to become immortal.  Instead, if the last
+reference to that string disappears, it will be removed from the interned
+string table.  This is not the case for the free-threaded build and any interned
+string will become immortal, surviving until interpreter shutdown.
+
+
+Non-GC objects have a larger object header
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The free-threaded build uses a different :c:type:`PyObject` structure.  Instead
+of having the GC related information allocated before the :c:type:`PyObject`
+structure, like in the default build, the GC related info is part of the normal
+object header.  For example, on the AMD64 platform, ``None`` uses 32 bytes on
+the free-threaded build vs 16 bytes for the default build.  GC objects (such as
+dicts and lists) are the same size for both builds since the free-threaded
+build does not use additional space for the GC info.
+
+
+QSBR can delay freeing of memory
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In order to safely implement lock-free data structures, a safe memory
+reclamation (SMR) scheme is used, known as quiescent state-based reclamation
+(QSBR).  This means that the memory backing data structures allowing lock-free
+access will use QSBR, which defers the free operation, rather than immediately
+freeing the memory.  Two examples of these data structures are the list object
+and the dictionary keys object.  See ``InternalDocs/qsbr.md`` in the CPython
+source tree for more details on how QSBR is implemented.  Running
+:func:`gc.collect` should cause all memory being held by QSBR to be actually
+freed.  Note that even when QSBR frees the memory, the underlying memory
+allocator may not immediately return that memory to the OS and so the resident
+set size (RSS) of the process might not decrease.
+
+
+mimalloc allocator vs pymalloc
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The default build will normally use the "pymalloc" memory allocator for small
+allocations (512 bytes or smaller).  The free-threaded build does not use
+pymalloc and allocates all Python objects using the "mimalloc" allocator.  The
+pymalloc allocator has the following properties that help keep memory usage
+low: small per-allocated-block overhead, effective memory fragmentation
+prevention, and quick return of free memory to the operating system.  The
+mimalloc allocator does quite well in these respects as well but can have some
+more overhead.
+
+In the free-threaded build, mimalloc manages memory in a number of separate
+heaps (currently four).  For example, all GC supporting objects are allocated
+from their own heap.  Using separate heaps means that free memory in one heap
+cannot be used for an allocation that uses another heap.  Also, some heaps are
+configured to use QSBR (quiescent-state based reclamation) when freeing the
+memory that backs up the heap (known as "pages" in mimalloc terminology).  The
+use of QSBR creates a delay between all memory blocks for a page being freed
+and the memory page being released, either for new allocations or back to the
+OS.
+
+The mimalloc allocator also defers returning freed memory back to the OS.  You
+can reduce that delay by setting the environment variable
+:envvar:`!MIMALLOC_PURGE_DELAY` to ``0``.  Note that this will likely reduce
+the performance of the allocator.
+
+
+Free-threaded reference counting can cause objects to live longer
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In the default build, when an object's reference count reaches zero, it is
+normally deallocated.  The free-threaded build uses "biased reference
+counting", with a fast-path for objects "owned" by the current thread and a
+slow path for other objects.  See :pep:`703` for additional details.  Any time
+an object's reference count ends up in a "queued" state, deallocation can be
+deferred.  The queued state is cleared from the "eval breaker" section of the
+bytecode evaluator.
+
+The free-threaded build also allows a different mode of reference counting,
+known as "deferred reference counting".  This mode is enabled by setting a flag
+on a per-object basis.  Deferred reference counting is enabled for the
+following types:
+
+* module objects
+* module top-level functions
+* class methods defined in the class scope
+* descriptor objects
+* thread-local objects, created by :class:`threading.local`
+
+When deferred reference counting is enabled, references from Python function
+stacks are not added to the reference count.  This scheme reduces the overhead
+of reference counting, especially for objects used from multiple threads.
+Because the stack references are not counted, objects with deferred reference
+counting are not immediately freed when their internal reference count goes to
+zero.  Instead, they are examined by the next GC run and, if no stack
+references to them are found, they are freed.  This means these objects are
+freed by the GC and not when their reference count goes to zero, as is typical.
+
+
+Per-thread reference counting can delay freeing objects
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To avoid contention on the reference count fields of frequently shared
+objects, the free-threaded build also uses "per-thread reference counting"
+for a few selected object types.  Rather than updating a single shared
+reference count, each thread maintains its own local reference count array,
+indexed by a unique id assigned to the object.  The true reference count is
+only computed by summing the per-thread counts when the object's local
+count drops to zero.  Per-thread reference counting is currently used for:
+
+* heap type objects (classes created in Python)
+* code objects
+* the ``__dict__`` of module objects
+
+Because the per-thread counts must be merged back to the object before it
+can be deallocated, objects using per-thread reference counting are
+typically freed later than they would be in the default build.  In
+particular, such an object is usually not freed until the thread that
+referenced it reaches a safe point (for example, in the "eval breaker"
+section of the bytecode evaluator) or exits.  Running :func:`gc.collect`
+will merge the per-thread counts and allow these objects to be freed.

+.. _remote-debugging-threat-model:
+
+Security and threat model
+=========================
+
+The remote debugging protocol relies on the same operating system primitives
+used by native debuggers such as GDB and LLDB.  Attaching to a process
+requires the **same privileges** that those debuggers require, for example
+``ptrace`` / Yama LSM on Linux, ``task_for_pid`` on macOS, and
+``SeDebugPrivilege`` on Windows.  Python does not introduce any new privilege
+escalation path; if an attacker already possesses the permissions needed to
+attach to a process, they could equally use GDB to read memory or inject
+code.
+
+The following principles define what is, and is not, considered a security
+vulnerability in this feature:
+
+Attaching requires OS-level privileges
+   On every supported platform the operating system gates cross-process
+   memory access behind privilege checks (``CAP_SYS_PTRACE``, root, or
+   administrator rights).  A report that demonstrates an issue only after
+   these privileges have already been obtained is **not** a vulnerability in
+   CPython, since the OS security boundary was already crossed.
+
+Crashes or memory errors when reading a compromised process are not vulnerabilities
+   A tool that reads internal interpreter state from a target process must
+   trust that memory to be well-formed.  If the target process has been
+   corrupted or is controlled by an attacker, the debugger or profiler may
+   crash, produce garbage output, or behave unpredictably.  This is the same
+   risk accepted by every ``ptrace``-based debugger.  Bugs in this category
+   (buffer overflows, segmentation faults, or undefined behaviour triggered
+   by reading corrupted state) are **not** treated as security issues, though
+   fixes that improve robustness are welcome.
+
+Vulnerabilities in the target process are not in scope
+   If the Python process being debugged has already been compromised, the
+   attacker already controls execution in that process.  Demonstrating further
+   impact from that starting point does not constitute a vulnerability in the
+   remote debugging protocol.
+
+When to use ``PYTHON_DISABLE_REMOTE_DEBUG``
+-------------------------------------------
+
+The environment variable :envvar:`PYTHON_DISABLE_REMOTE_DEBUG` (and the
+equivalent :option:`-X disable_remote_debug` flag) allows operators to disable
+the in-process side of the protocol as a **defence-in-depth** measure.  This
+may be useful in hardened or sandboxed deployment environments where no
+debugging or profiling of the process is expected and reducing attack surface
+is a priority, even though the OS-level privilege checks already prevent
+unprivileged access.
+
+Setting this variable does **not** affect other OS-level debugging interfaces
+(``ptrace``, ``/proc``, ``task_for_pid``, etc.), which remain available
+according to their own permission models.

+Asynchronous generators best practices
+======================================
+
+Writing correct and efficient asyncio code requires awareness of certain pitfalls.
+This section outlines essential best practices that can save you hours of debugging.
+
+
+Close asynchronous generators explicitly
+----------------------------------------
+
+It is recommended to manually close the
+:term:`asynchronous generator <asynchronous generator iterator>`. If a generator
+exits early - for example, due to an exception raised in the body of
+an ``async for`` loop - its asynchronous cleanup code may run in an
+unexpected context. This can occur after the tasks it depends on have completed,
+or during the event loop shutdown when the async-generator's garbage collection
+hook is called.
+
+To avoid this, explicitly close the generator by calling its
+:meth:`~agen.aclose` method, or use the :func:`contextlib.aclosing`
+context manager::
+
+  import asyncio
+  import contextlib
+
+  async def gen():
+    yield 1
+    yield 2
+
+  async def func():
+    async with contextlib.aclosing(gen()) as g:
+      async for x in g:
+        break  # Don't iterate until the end
+
+  asyncio.run(func())
+
+As noted above, the cleanup code for these asynchronous generators is deferred.
+The following example demonstrates that the finalization of an asynchronous
+generator can occur in an unexpected order::
+
+  import asyncio
+  work_done = False
+
+  async def cursor():
+      try:
+          yield 1
+      finally:
+          assert work_done
+
+  async def rows():
+      global work_done
+      try:
+          yield 2
+      finally:
+          await asyncio.sleep(0.1) # imitate some async work
+          work_done = True
+
+
+  async def main():
+      async for c in cursor():
+          async for r in rows():
+              break
+          break
+
+  asyncio.run(main())
+
+For this example, we get the following output::
+
+  unhandled exception during asyncio.run() shutdown
+  task: <Task finished name='Task-3' coro=<<async_generator_athrow without __name__>()> exception=AssertionError()>
+  Traceback (most recent call last):
+    File "example.py", line 6, in cursor
+      yield 1
+  asyncio.exceptions.CancelledError
+
+  During handling of the above exception, another exception occurred:
+
+  Traceback (most recent call last):
+    File "example.py", line 8, in cursor
+      assert work_done
+             ^^^^^^^^^
+  AssertionError
+
+The ``cursor()`` asynchronous generator was finalized before the ``rows``
+generator - an unexpected behavior.
+
+The example can be fixed by explicitly closing the
+``cursor`` and ``rows`` async-generators::
+
+  async def main():
+      async with contextlib.aclosing(cursor()) as cursor_gen:
+          async for c in cursor_gen:
+              async with contextlib.aclosing(rows()) as rows_gen:
+                  async for r in rows_gen:
+                      break
+              break
+
+
+Create asynchronous generators only when the event loop is running
+------------------------------------------------------------------
+
+It is recommended to create
+:term:`asynchronous generators <asynchronous generator iterator>` only after
+the event loop has been created.
+
+To ensure that asynchronous generators close reliably, the event loop uses the
+:func:`sys.set_asyncgen_hooks` function to register callback functions. These
+callbacks update the list of running asynchronous generators to keep it in a
+consistent state.
+
+When the :meth:`loop.shutdown_asyncgens() <asyncio.loop.shutdown_asyncgens>`
+function is called, the running generators are stopped gracefully and the
+list is cleared.
+
+The asynchronous generator invokes the corresponding system hook during its
+first iteration. At the same time, the generator records that the hook has
+been called and does not call it again.
+
+Therefore, if iteration begins before the event loop is created,
+the event loop will not be able to add the generator to its list of active
+generators because the hooks are set after the generator attempts to call them.
+Consequently, the event loop will not be able to terminate the generator
+if necessary.
+
+Consider the following example::
+
+  import asyncio
+
+  async def agenfn():
+      try:
+          yield 10
+      finally:
+          await asyncio.sleep(0)
+
+
+  with asyncio.Runner() as runner:
+      agen = agenfn()
+      print(runner.run(anext(agen)))
+      del agen
+
+Output::
+
+  10
+  Exception ignored while closing generator <async_generator object agenfn at 0x000002F71CD10D70>:
+  Traceback (most recent call last):
+    File "example.py", line 13, in <module>
+      del agen
+          ^^^^
+  RuntimeError: async generator ignored GeneratorExit
+
+This example can be fixed as follows::
+
+  import asyncio
+
+  async def agenfn():
+      try:
+          yield 10
+      finally:
+          await asyncio.sleep(0)
+
+  async def main():
+      agen = agenfn()
+      print(await anext(agen))
+      del agen
+
+  asyncio.run(main())
+
+
+Avoid concurrent iteration and closure of the same generator
+------------------------------------------------------------
+
+Async generators may be reentered while another
+:meth:`~agen.__anext__` / :meth:`~agen.athrow` / :meth:`~agen.aclose` call is in
+progress. This may lead to an inconsistent state of the async generator and can
+cause errors.
+
+Let's consider the following example::
+
+  import asyncio
+
+  async def consumer():
+      for idx in range(100):
+          await asyncio.sleep(0)
+          message = yield idx
+          print('received', message)
+
+  async def amain():
+      agenerator = consumer()
+      await agenerator.asend(None)
+
+      fa = asyncio.create_task(agenerator.asend('A'))
+      fb = asyncio.create_task(agenerator.asend('B'))
+      await fa
+      await fb
+
+  asyncio.run(amain())
+
+Output::
+
+  received A
+  Traceback (most recent call last):
+    File "test.py", line 38, in <module>
+      asyncio.run(amain())
+      ~~~~~~~~~~~^^^^^^^^^
+    File "Lib/asyncio/runners.py", line 204, in run

+    File "test.py", line 36, in amain
+      await fb
+  RuntimeError: anext(): asynchronous generator is already running
+
+
+Therefore, it is recommended to avoid using asynchronous generators in parallel

+asyncio and free-threaded Python
+================================
+
+asyncio uses an event loop as a scheduler to enable highly efficient
+concurrency by switching between tasks to allow non-blocking I/O
+operations. This results in better performance for I/O-bound use
+cases. It also allows off-loading CPU-bound work to a thread or
+process pool, but that is still limited by the :term:`global
+interpreter lock` in CPython.
+
+However, in :ref:`free-threaded Python <freethreading-python-howto>`,
+the GIL is disabled and Python can run true multi-threaded code. This
+means that asyncio can now take advantage of multiple CPU cores without
+the limitations imposed by the GIL.
+
+Since Python 3.14, asyncio has first-class support for free-threaded
+Python, and the implementation of asyncio is safe to use in a
+multi-threaded environment.
+
+A single event loop on one core can handle many connections
+concurrently, but the Python code that runs to handle each one still
+executes serially. Once requests involve a non-trivial amount of
+per-request computation, that handling becomes the bottleneck, and a
+single core can no longer keep up. Combining asyncio with threads is
+most useful here: by running an event loop per thread, the handling of
+different requests can run in parallel across multiple CPU cores. It is
+also useful when you need to run blocking or CPU-bound code from an
+asyncio application.
+
+
+.. seealso::
+
+   `Scaling asyncio on Free-Threaded Python
+   <https://labs.quansight.org/blog/scaling-asyncio-on-free-threaded-python>`__,
+   a blog post by Kumar Aditya which explains the internal changes
+   that make asyncio safe and efficient under free-threaded Python,
+   together with benchmarks of the resulting improvements.
+
+
+Thread safety considerations
+----------------------------
+
+While asyncio is designed to be thread-safe in a free-threaded Python
+environment, there are still some considerations to keep in mind when
+using asyncio with threads:
+
+1. **Event loop**: Each thread should have its own event loop which
+   should not be shared across threads. This ensures that the event loop
+   can manage its own tasks and callbacks without interference from
+   other threads.
+
+2. **Task management**: Tasks and futures created in one thread should
+   not be awaited or manipulated from another thread.
+
+3. **Thread-safe APIs**: When interacting with asyncio from multiple
+   threads, it's important to use thread-safe APIs provided by asyncio,
+   such as :func:`asyncio.run_coroutine_threadsafe` for submitting
+   coroutines to an event loop from another thread. If you need to
+   call a callback from a different thread, you can use
+   :meth:`loop.call_soon_threadsafe` to schedule it safely.
+
+4. **Synchronization**: The synchronization primitives provided by
+   asyncio (like :class:`asyncio.Lock` and :class:`asyncio.Event`)
+   are not designed to be used across threads. If you need to
+   synchronize between threads, you should use the synchronization
+   primitives from the :mod:`threading` module instead.
+
+
+Using asyncio with threads
+--------------------------
+
+asyncio supports running one event loop per thread, which allows you to
+take advantage of multiple CPU cores in a free-threaded Python
+environment. Each thread can run its own event loop, and tasks can be
+scheduled on those loops independently.
+
+Here's an example of how to use asyncio with threads::
+
+    import asyncio
+    import threading
+
+    async def worker(name: str) -> None:
+        print(f"Worker {name} starting")
+        await asyncio.sleep(1)
+        print(f"Worker {name} done")
+
+    def run_loop(name: str) -> None:
+        asyncio.run(worker(name))
+
+    threads = [
+        threading.Thread(target=run_loop, args=(f"T{i}",))
+        for i in range(4)
+    ]
+    for t in threads:
+        t.start()
+    for t in threads:
+        t.join()
+
+In this example, each thread creates its own event loop with
+:func:`asyncio.run` and runs a coroutine on it. The threads execute
+concurrently, and in a free-threaded build they can run on separate
+CPU cores in parallel.
+
+
+Producer/consumer across threads
+--------------------------------
+
+When a regular (non-asyncio) thread needs to hand work to an asyncio
+event loop running in another thread, use a thread-safe primitive such
+as :class:`queue.Queue` rather than :class:`asyncio.Queue`, which is
+only safe within a single event loop.::
+
+    import asyncio
+    import queue
+    import threading
+
+    def producer(q: queue.Queue[int]) -> None:
+        for i in range(5):
+            print(f"Producing {i}")
+            q.put(i)
+        q.shutdown()
+
+    async def consumer(q: queue.Queue[int]) -> None:
+        while True:
+            try:
+                item = q.get_nowait()
+            except queue.Empty:
+                await asyncio.sleep(0.1)
+                continue
+            except queue.ShutDown:
+                break
+            print(f"Consumed {item}")
+            await asyncio.sleep(item)
+
+    q: queue.Queue[int] = queue.Queue()
+    consumer_thread = threading.Thread(
+        target=lambda: asyncio.run(consumer(q))
+    )
+    consumer_thread.start()
+    producer(q)
+    consumer_thread.join()
+
+The producer runs on the main thread while the consumer runs inside an
+event loop on its own thread, yet they communicate safely through
+``queue.Queue``. When the queue is empty the consumer sleeps briefly
+and tries again. When the producer is done it calls
+:meth:`~queue.Queue.shutdown`, which causes subsequent
+:meth:`~queue.Queue.get_nowait` calls to raise :exc:`queue.ShutDown`
+so the consumer can exit cleanly.

 Loading shared libraries
 ^^^^^^^^^^^^^^^^^^^^^^^^
 
 There are several ways to load shared libraries into the Python process.  One
-way is to instantiate one of the following classes:
+way is to instantiate :py:class:`CDLL` or one of its subclasses:
 
 
 .. class:: CDLL(name, mode=DEFAULT_MODE, handle=None, use_errno=False, use_last_error=False, winmode=None)
 
-   Instances of this class represent loaded shared libraries. Functions in these
-   libraries use the standard C calling convention, and are assumed to return
-   :c:expr:`int`.
+   Represents a loaded shared library.
+
+   Functions in this library use the standard C calling convention, and are
+   assumed to return :c:expr:`int`.
+   The Python :term:`global interpreter lock` is released before calling any
+   function exported by these libraries, and reacquired afterwards.
+   For different function behavior, use a subclass: :py:class:`~ctypes.OleDLL`,
+   :py:class:`~ctypes.WinDLL`, or :py:class:`~ctypes.PyDLL`.
+
+   If you have an existing :py:attr:`handle <ctypes.CDLL._handle>` to an already
+   loaded shared library, it can be passed as the *handle* argument to wrap
+   the opened library in a new :py:class:`!CDLL` object.
+   In this case, *name* is only used to set the :py:attr:`~ctypes.CDLL._name`
+   attribute, but it may be adjusted and/or validated.
+
+   If *handle* is ``None``, the underlying platform's :manpage:`dlopen(3)` or
+   `LoadLibraryExW`_ function is used to load the library into
+   the process, and to get a handle to it.
+
+   *name* is the pathname of the shared library to open.
+   If *name* does not contain a path separator, the library is found
+   in a platform-specific way.
+
+   On Windows, the ``.DLL`` suffix may be missing. (For details, see
+   `LoadLibraryExW`_ documentation.)
+   Other platform-specific prefixes and suffixes (for example, ``lib``,
+   ``.so``, ``.dylib``, or version numbers) must be present in *name*;
+   they are not added automatically.
+   See :ref:`ctypes-finding-shared-libraries` for more information.
+
+   On non-Windows systems, *name* can  be ``None``. In this case,
+   :c:func:`!dlopen` is called with ``NULL``, which opens the main program
+   as a "library".
+   (Some systems do the same is *name* is empty; ``None``/``NULL`` is more
+   portable.)
+
+   .. admonition:: CPython implementation detail
+
+      Since CPython is linked to ``libc``, a ``None`` *name* is often used
+      to access the C standard library::
+
+         >>> printf = ctypes.CDLL(None).printf
+         >>> printf.argtypes = [ctypes.c_char_p]
+         >>> printf(b"hello\n")
+         hello
+         6
+
+      To access the Python C API, prefer :py:data:`ctypes.pythonapi` which
+      works across platforms.
+
+   The *mode* parameter can be used to specify how the library is loaded.  For
+   details, consult the :manpage:`dlopen(3)` manpage.  On Windows, *mode* is
+   ignored.  On posix systems, RTLD_NOW is always added, and is not
+   configurable.
+
+   The *use_errno* parameter, when set to true, enables a ctypes mechanism that
+   allows accessing the system :data:`errno` error number in a safe way.
+   :mod:`!ctypes` maintains a thread-local copy of the system's :data:`errno`
+   variable; if you call foreign functions created with ``use_errno=True`` then the
+   :data:`errno` value before the function call is swapped with the ctypes private
+   copy, the same happens immediately after the function call.
+
+   The function :func:`ctypes.get_errno` returns the value of the ctypes private
+   copy, and the function :func:`ctypes.set_errno` changes the ctypes private copy
+   to a new value and returns the former value.
+
+   The *use_last_error* parameter, when set to true, enables the same mechanism for
+   the Windows error code which is managed by the :func:`GetLastError` and
+   :func:`!SetLastError` Windows API functions; :func:`ctypes.get_last_error` and
+   :func:`ctypes.set_last_error` are used to request and change the ctypes private
+   copy of the windows error code.
+
+   The *winmode* parameter is used on Windows to specify how the library is loaded
+   (since *mode* is ignored). It takes any value that is valid for the Win32 API
+   `LoadLibraryExW`_ flags parameter. When omitted, the default is to use the

+Listing loaded shared libraries
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When writing code that relies on code loaded from shared libraries, it can be
+useful to know which shared libraries have already been loaded into the current
+process.
+
+The :mod:`!ctypes.util` module provides the :func:`~ctypes.util.dllist` function,
+which calls the different APIs provided by the various platforms to help determine
+which shared libraries have already been loaded into the current process.
+
+The exact output of this function will be system dependent. On most platforms,
+the first entry of this list represents the current process itself, which may
+be an empty string.
+For example, on glibc-based Linux, the return may look like::
+
+   >>> from ctypes.util import dllist
+   >>> dllist()
+   ['', 'linux-vdso.so.1', '/lib/x86_64-linux-gnu/libm.so.6', '/lib/x86_64-linux-gnu/libc.so.6', ... ]

+   The curses library does "line-breakout optimization" by looking for typeahead
+   periodically while updating the screen.  If input is found, and it is coming

+.. function:: newpad(nlines, ncols)
 
-.. function:: set_escdelay(ms)
+   Create and return a pointer to a new pad data structure with the given number

-   Sets the number of milliseconds to wait after reading an escape character,
-   to distinguish between an individual escape character entered on the
-   keyboard from escape sequences sent by cursor and function keys.
+   A pad is like a window, except that it is not restricted by the screen size, and
+   is not necessarily associated with a particular part of the screen.  Pads can be
+   used when a large window is needed, and only a part of the window will be on the
+   screen at one time.  Automatic refreshes of pads (such as from scrolling or
+   echoing of input) do not occur.  The :meth:`~window.refresh` and :meth:`~window.noutrefresh`
+   methods of a pad require 6 arguments to specify the part of the pad to be
+   displayed and the location on the screen to be used for the display. The
+   arguments are *pminrow*, *pmincol*, *sminrow*, *smincol*, *smaxrow*, *smaxcol*; the *p*
+   arguments refer to the upper-left corner of the pad region to be displayed and

-   .. versionadded:: 3.9
+The following functions manage *soft-label keys*, a row of labels displayed
+along the bottom line of the screen, typically used to label a row of function
+keys.  :func:`slk_init` must be called before :func:`initscr` or
+:func:`newterm`; it takes one screen line away from the standard window for the
+labels.
 
-.. function:: set_tabsize(size)
 
-   Sets the number of columns used by the curses library when converting a tab
-   character to spaces as it adds the tab to a window.
+.. function:: slk_init(fmt=0)
 
-   .. versionadded:: 3.9
+   Reserve a screen line for the soft labels and choose their layout.  *fmt*
+   selects the arrangement: ``0`` for 3-2-3 (eight labels), ``1`` for 4-4
+   (eight labels).  Where the underlying curses library supports them, ``2``
+   gives 4-4-4 (twelve labels) and ``3`` gives 4-4-4 with an index line.
 
-.. function:: setsyx(y, x)
+   Must be called before :func:`initscr` or :func:`newterm`.
 
-   Set the virtual screen cursor to *y*, *x*. If *y* and *x* are both ``-1``, then

-   :envvar:`TERM` environment variable will be used.  *fd* is the
-   file descriptor to which any initialization sequences will be sent; if not
-   supplied or ``-1``, the file descriptor for ``sys.stdout`` will be used.
+   Set the text of soft label number *labnum*, in the range ``1`` through ``8``
+   (or ``12`` in a twelve-label layout).  *justify* controls how *label* is
+   placed within the label: ``0`` for left, ``1`` for centered, ``2`` for right.

+.. function:: slk_label(labnum)
 
-   :func:`start_color` initializes eight basic colors (black, red,  green, yellow,
-   blue, magenta, cyan, and white), and two global variables in the :mod:`curses`
-   module, :const:`COLORS` and :const:`COLOR_PAIRS`, containing the maximum number
-   of colors and color-pairs the terminal can support.  It also restores the colors
-   on the terminal to the values they had when the terminal was just turned on.

-.. function:: tigetflag(capname)
+   Update the soft labels on the virtual screen, like

+   screen updates.
 
-   Return the value of the Boolean capability corresponding to the terminfo

-   Instantiate the bytes object *str* with the supplied parameters, where *str* should
-   be a parameterized string obtained from the terminfo database.  E.g.
-   ``tparm(tigetstr("cup"), 5, 3)`` could result in ``b'\033[6;4H'``, the exact

+.. function:: slk_touch()
 
-.. function:: typeahead(fd)
+   Force all the soft labels to be redrawn by the next :func:`slk_refresh` or

-   Specify that the file descriptor *fd* be used for typeahead checking.  If *fd*
-   is ``-1``, then no typeahead checking is done.
+   .. versionadded:: next
 
-   The curses library does "line-breakout optimization" by looking for typeahead
-   periodically while updating the screen.  If input is found, and it is coming
-   from a tty, the current update is postponed until refresh or doupdate is called
-   again, allowing faster response to commands typed in advance. This function

+Complex character objects
+-------------------------
+
+.. class:: complexchar(text, /, attr=0, pair=0)
+
+   A *complex character* (or *complexchar*) is an immutable styled
+   character cell: a spacing character optionally followed by combining
+   characters, together with a set of attributes and a color pair.
+
+   *text* is the cell's text, *attr* a combination of the
+   :ref:`WA_* attributes <curses-wa-constants>` (equivalent to the matching
+   ``A_*`` constants), and *pair* a color pair number.  Unlike the packed
+   :class:`chtype <int>` used by :meth:`~window.inch` and the ``A_*`` methods,
+   the color pair is stored separately and is not limited to the value that
+   fits in a :func:`color_pair`.
+
+   Complex characters are returned by :meth:`window.in_wch` and
+   :meth:`window.getbkgrnd`, and are accepted (along with an integer, a byte
+   or a string) by the character-cell methods such as :meth:`window.addch`,
+   :meth:`window.insch`, :meth:`window.bkgd`, :meth:`window.border`,
+   :meth:`window.hline` and :meth:`window.vline`.  A complex character already
+   carries its own rendition, so it cannot be combined with an explicit *attr*
+   argument.
+
+   :func:`str` returns the cell's text; two complex characters are equal when
+   their text, attributes and color pair all match.
+
+   The same code works on both wide- and narrow-character builds.  On a narrow
+   build a cell holds a single character (no combining marks) that must encode to
+   one byte in the window's encoding (8-bit locales only), and *pair* is limited
+   to the value that fits in a :func:`color_pair`.
+
+   .. attribute:: attr
+
+      The attributes of the character cell (read-only).
+
+   .. attribute:: pair
+
+      The color pair number of the character cell (read-only).
+
+   .. versionadded:: next
+
+
+.. class:: complexstr(cells[, attr[, pair]])
+
+   A *complex character string* (or *complexstr*) is an immutable sequence of
+   styled character cells -- the string counterpart of
+   :class:`complexchar` (as :class:`str` is to a single character).
+
+   If *cells* is a string, it is split into character cells (each a spacing
+   character optionally followed by combining characters), and *attr* (a
+   combination of the :ref:`WA_* attributes <curses-wa-constants>`) and *pair*
+   (a color pair number), if given, are applied to every cell.
+
+   Otherwise *cells* is an iterable whose items are themselves cells, each a
+   :class:`complexchar` or a string; each item then carries its own rendition,
+   and *attr* and *pair* must be omitted.
+
+   It is returned by :meth:`window.in_wchstr`, and accepted by
+   :meth:`window.addstr`, :meth:`~window.addnstr`, :meth:`~window.insstr` and
+   :meth:`~window.insnstr`, so a run read from a window can be written back
+   unchanged.
+
+   It behaves like an immutable sequence: ``len(s)`` is the number of cells,
+   ``s[i]`` is the *i*-th cell as a :class:`complexchar`, slicing and
+   concatenation produce new :class:`!complexstr` instances, and iterating
+   yields the cells.  :func:`str` returns the cells' text joined together, and
+   two complex character strings are equal when their cells all match.  It is
+   hashable.
+
+   To build or edit a run of cells, use an ordinary :class:`list` of
+   :class:`complexchar` (or strings); a :class:`!complexstr` is the immutable
+   form returned by a read.
+
+   Like :class:`complexchar`, this type works on both wide- and narrow-character
+   builds, with the same per-cell limitations on a narrow build.

-
-    *Superseded by TraversableResources*
-
-    An :term:`abstract base class` to provide the ability to read
-    *resources*.
-
-    From the perspective of this ABC, a *resource* is a binary
-    artifact that is shipped within a package. Typically this is
-    something like a data file that lives next to the ``__init__.py``
-    file of the package. The purpose of this class is to help abstract
-    out the accessing of such data files so that it does not matter if
-    the package and its data file(s) are stored e.g. in a zip file
-    versus on the file system.
-
-    For any of methods of this class, a *resource* argument is
-    expected to be a :term:`path-like object` which represents
-    conceptually just a file name. This means that no subdirectory
-    paths should be included in the *resource* argument. This is
-    because the location of the package the reader is for, acts as the
-    "directory". Hence the metaphor for directories and file
-    names is packages and resources, respectively. This is also why
-    instances of this class are expected to directly correlate to
-    a specific package (instead of potentially representing multiple
-    packages or a module).
-
-    Loaders that wish to support resource reading are expected to
-    provide a method called ``get_resource_reader(fullname)`` which
-    returns an object implementing this ABC's interface. If the module
-    specified by fullname is not a package, this method should return
-    :const:`None`. An object compatible with this ABC should only be
-    returned when the specified module is a package.

-        acceptable to return names for which :meth:`is_resource` would
-        be false.
-
-        Allowing non-resource names to be returned is to allow for
-        situations where how a package and its resources are stored
-        are known a priori and the non-resource names would be useful.
-        For instance, returning subdirectory names is allowed so that

-The :mod:`pickle` module differs from :mod:`marshal` in several significant ways:

-Introduction to the profilers
-=============================
+.. deprecated-removed:: 3.15 3.17
 
-.. index::
-   single: statistical profiling
-   single: profiling, statistical
-   single: deterministic profiling
-   single: profiling, deterministic
+The :mod:`!profile` module is deprecated and will be removed in Python 3.17.
+Use :mod:`profiling.tracing` instead.
 
-Python provides both :dfn:`statistical profiling` and :dfn:`deterministic profiling` of
-Python programs. A :dfn:`profile` is a set of statistics that describes how
-often and for how long various parts of the program executed. These statistics
-can be formatted into reports via the :mod:`pstats` module.
+The :mod:`!profile` module provides a pure Python implementation of a
+deterministic profiler. While useful for understanding profiler internals or
+extending profiler behavior through subclassing, its pure Python implementation
+introduces significant overhead compared to the C-based :mod:`profiling.tracing`
+module.
 
-The Python standard library provides three different profiling implementations:
+For most profiling tasks, use:
 
-**Statistical Profiler:**
+- :mod:`profiling.sampling` for production debugging with zero overhead
+- :mod:`profiling.tracing` for development and testing
 
-1. :mod:`!profiling.sampling` provides statistical profiling of running Python processes
-   using periodic stack sampling. It can attach to any running Python process without
-   requiring code modification or restart, making it ideal for production debugging.
 
-**Deterministic Profilers:**
+Migration
+=========
 
-2. :mod:`cProfile` is recommended for development and testing; it's a C extension with
-   reasonable overhead that makes it suitable for profiling long-running
-   programs.  Based on :mod:`lsprof`, contributed by Brett Rosen and Ted
-   Czotter.
+Migrating from :mod:`!profile` to :mod:`profiling.tracing` is straightforward.
+The APIs are compatible::
 
-3. :mod:`profile`, a pure Python module whose interface is imitated by
-   :mod:`cProfile`, but which adds significant overhead to profiled programs.
-   If you're trying to extend the profiler in some way, the task might be easier
-   with this module.  Originally designed and written by Jim Roskind.
+   # Old (deprecated)
+   import profile
+   profile.run('my_function()')
 
-.. note::
+   # New (recommended)
+   import profiling.tracing
+   profiling.tracing.run('my_function()')
 
-   The profiler modules are designed to provide an execution profile for a given
-   program, not for benchmarking purposes (for that, there is :mod:`timeit` for
-   reasonably accurate results).  This particularly applies to benchmarking
-   Python code against C code: the profilers introduce overhead for Python code,
-   but not for C-level functions, and so the C code would seem faster than any
-   Python one.

+For most code, replacing ``import profile`` with ``import profiling.tracing``
+(and using ``profiling.tracing`` instead of ``profile`` throughout) provides
+a straightforward migration path.
 
 .. note::
 
-   The statistical profiler (:mod:`!profiling.sampling`) is recommended for most production
-   use cases due to its extremely low overhead and ability to profile running processes
-   without modification. It can attach to any Python process and collect performance
-   data with minimal impact on execution speed, making it ideal for debugging
-   performance issues in live applications.
-
-
-.. _statistical-profiling:
-
-What Is Statistical Profiling?
-==============================
-
-:dfn:`Statistical profiling` works by periodically interrupting a running
-program to capture its current call stack. Rather than monitoring every
-function entry and exit like deterministic profilers, it takes snapshots at
-regular intervals to build a statistical picture of where the program spends
-its time.
-
-The sampling profiler uses process memory reading (via system calls like
-``process_vm_readv`` on Linux, ``vm_read`` on macOS, and ``ReadProcessMemory`` on
-Windows) to attach to a running Python process and extract stack trace
-information without requiring any code modification or restart of the target
-process. This approach provides several key advantages over traditional
-profiling methods.
-
-The fundamental principle is that if a function appears frequently in the
-collected stack samples, it is likely consuming significant CPU time. By
-analyzing thousands of samples, the profiler can accurately estimate the
-relative time spent in different parts of the program. The statistical nature
-means that while individual measurements may vary, the aggregate results
-converge to represent the true performance characteristics of the application.
-
-Since statistical profiling operates externally to the target process, it
-introduces virtually no overhead to the running program. The profiler process
-runs separately and reads the target process memory without interrupting its
-execution. This makes it suitable for profiling production systems where
-performance impact must be minimized.
-
-The accuracy of statistical profiling improves with the number of samples
-collected. Short-lived functions may be missed or underrepresented, while
-long-running functions will be captured proportionally to their execution time.
-This characteristic makes statistical profiling particularly effective for
-identifying the most significant performance bottlenecks rather than providing
-exhaustive coverage of all function calls.
-
-Statistical profiling excels at answering questions like "which functions
-consume the most CPU time?" and "where should I focus optimization efforts?"
-rather than "exactly how many times was this function called?" The trade-off
-between precision and practicality makes it an invaluable tool for performance
-analysis in real-world applications.

-Instant User's Manual
-=====================
-
-This section is provided for users that "don't want to read the manual." It
-provides a very brief overview, and allows a user to rapidly perform profiling
-on an existing application.
-
-**Statistical Profiling (Recommended for Production):**
-
-To profile an existing running process::
-
-   python -m profiling.sampling 1234
-
-To profile with custom settings::
-
-   python -m profiling.sampling -i 50 -d 30 1234
-
-**Deterministic Profiling (Development/Testing):**
-
-To profile a function that takes a single argument, you can do::
-
-   import cProfile
-   import re
-   cProfile.run('re.compile("foo|bar")')
-
-(Use :mod:`profile` instead of :mod:`cProfile` if the latter is not available on
-your system.)
-
-The above action would run :func:`re.compile` and print profile results like
-the following::
-
-         214 function calls (207 primitive calls) in 0.002 seconds
-
-   Ordered by: cumulative time
-
-   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
-        1    0.000    0.000    0.002    0.002 {built-in method builtins.exec}
-        1    0.000    0.000    0.001    0.001 <string>:1(<module>)
-        1    0.000    0.000    0.001    0.001 __init__.py:250(compile)
-        1    0.000    0.000    0.001    0.001 __init__.py:289(_compile)
-        1    0.000    0.000    0.000    0.000 _compiler.py:759(compile)
-        1    0.000    0.000    0.000    0.000 _parser.py:937(parse)
-        1    0.000    0.000    0.000    0.000 _compiler.py:598(_code)
-        1    0.000    0.000    0.000    0.000 _parser.py:435(_parse_sub)
-
-The first line indicates that 214 calls were monitored.  Of those calls, 207
-were :dfn:`primitive`, meaning that the call was not induced via recursion. The
-next line: ``Ordered by: cumulative time`` indicates the output is sorted
-by the ``cumtime`` values. The column headings include:
-
-ncalls
-   for the number of calls.
-
-tottime
-   for the total time spent in the given function (and excluding time made in
-   calls to sub-functions)
-
-percall
-   is the quotient of ``tottime`` divided by ``ncalls``
-
-cumtime
-   is the cumulative time spent in this and all subfunctions (from invocation
-   till exit). This figure is accurate *even* for recursive functions.
-
-percall
-   is the quotient of ``cumtime`` divided by primitive calls
-
-filename:lineno(function)
-   provides the respective data of each function
-
-When there are two numbers in the first column (for example ``3/1``), it means
-that the function recursed.  The second value is the number of primitive calls
-and the former is the total number of calls.  Note that when the function does
-not recurse, these two values are the same, and only the single figure is
-printed.
-
-Instead of printing the output at the end of the profile run, you can save the
-results to a file by specifying a filename to the :func:`run` function::
-
-   import cProfile
-   import re
-   cProfile.run('re.compile("foo|bar")', 'restats')
-
-The :class:`pstats.Stats` class reads profile results from a file and formats
-them in various ways.

-
-Statistical Profiler Command Line Interface
-===========================================
-
-.. program:: profiling.sampling
-
-The :mod:`!profiling.sampling` module can be invoked as a script to profile running processes::

-
-**Understanding Statistical Profile Output:**
-
-The statistical profiler produces output similar to deterministic profilers but with different column meanings::
-
-   Profile Stats:
-          nsamples  sample%     tottime (ms)  cumul%    cumtime (ms)  filename:lineno(function)
-             45/67     12.5        23.450     18.6        56.780     mymodule.py:42(process_data)

-
-**Column Meanings:**
-
-- **nsamples**: ``direct/cumulative`` - Times function was directly executing / on call stack
-- **sample%**: Percentage of total samples where function was directly executing
-- **tottime**: Estimated time spent directly in this function
-- **cumul%**: Percentage of samples where function was anywhere on call stack
-- **cumtime**: Estimated cumulative time including called functions
-- **filename:lineno(function)**: Location and name of the function

-
-   Sample a Python process and generate profiling data.
-
-   This is the main entry point for statistical profiling. It creates a
-   :class:`SampleProfiler`, collects stack traces from the target process, and
-   outputs the results in the specified format.
-
-   :param int pid: Process ID of the target Python process
-   :param int sort: Sort order for pstats output (default: 2 for cumulative time)
-   :param int sample_interval_usec: Sampling interval in microseconds (default: 100)
-   :param int duration_sec: Duration to sample in seconds (default: 10)
-   :param str filename: Output filename (None for stdout/default naming)
-   :param bool all_threads: Whether to sample all threads (default: False)
-   :param int limit: Maximum number of functions to display (default: None)
-   :param bool show_summary: Whether to show summary statistics (default: True)
-   :param str output_format: Output format - 'pstats' or 'collapsed' (default: 'pstats')
-   :param bool realtime_stats: Whether to display real-time statistics (default: False)
-
-   :raises ValueError: If output_format is not 'pstats' or 'collapsed'
-
-   Examples::
-
-       # Basic usage - profile process 1234 for 10 seconds
-       import profiling.sampling
-       profiling.sampling.sample(1234)
-
-       # Profile with custom settings
-       profiling.sampling.sample(1234, duration_sec=30, sample_interval_usec=50, all_threads=True)
-
-       # Generate collapsed stack traces for flamegraph.pl
-       profiling.sampling.sample(1234, output_format='collapsed', filename='profile.collapsed')
-
-.. class:: SampleProfiler(pid, sample_interval_usec, all_threads)
-
-   Low-level API for the statistical profiler.
-
-   This profiler uses periodic stack sampling to collect performance data
-   from running Python processes with minimal overhead. It can attach to
-   any Python process by PID and collect stack traces at regular intervals.
-
-   :param int pid: Process ID of the target Python process
-   :param int sample_interval_usec: Sampling interval in microseconds
-   :param bool all_threads: Whether to sample all threads or just the main thread
-
-   .. method:: sample(collector, duration_sec=10)
-
-      Sample the target process for the specified duration.
-
-      Collects stack traces from the target process at regular intervals
-      and passes them to the provided collector for processing.
-
-      :param collector: Object that implements ``collect()`` method to process stack traces
-      :param int duration_sec: Duration to sample in seconds (default: 10)
-
-      The method tracks sampling statistics and can display real-time
-      information if realtime_stats is enabled.

-Deterministic Profiler Command Line Interface
-=============================================
-
-.. program:: cProfile
-
-The files :mod:`cProfile` and :mod:`profile` can also be invoked as a script to
-profile another script.  For example::
-
-   python -m cProfile [-o output_file] [-s sort_order] (-m module | myscript.py)
-
-.. option:: -o <output_file>
-
-   Writes the profile results to a file instead of to stdout.
-
-.. option:: -s <sort_order>
-
-   Specifies one of the :func:`~pstats.Stats.sort_stats` sort values
-   to sort the output by.
-   This only applies when :option:`-o <cProfile -o>` is not supplied.
-
-.. option:: -m <module>
-
-   Specifies that a module is being profiled instead of a script.
-
-   .. versionadded:: 3.7
-      Added the ``-m`` option to :mod:`cProfile`.
-
-   .. versionadded:: 3.8
-      Added the ``-m`` option to :mod:`profile`.
-
-The :mod:`pstats` module's :class:`~pstats.Stats` class has a variety of methods
-for manipulating and printing the data saved into a profile results file::
-
-   import pstats
-   from pstats import SortKey
-   p = pstats.Stats('restats')
-   p.strip_dirs().sort_stats(-1).print_stats()
-
-The :meth:`~pstats.Stats.strip_dirs` method removed the extraneous path from all
-the module names. The :meth:`~pstats.Stats.sort_stats` method sorted all the
-entries according to the standard module/line/name string that is printed. The
-:meth:`~pstats.Stats.print_stats` method printed out all the statistics.  You
-might try the following sort calls::
-
-   p.sort_stats(SortKey.NAME)
-   p.print_stats()
-
-The first call will actually sort the list by function name, and the second call
-will print out the statistics.  The following are some interesting calls to
-experiment with::
-
-   p.sort_stats(SortKey.CUMULATIVE).print_stats(10)
-
-This sorts the profile by cumulative time in a function, and then only prints
-the ten most significant lines.  If you want to understand what algorithms are
-taking time, the above line is what you would use.
-
-If you were looking to see what functions were looping a lot, and taking a lot
-of time, you would do::
-
-   p.sort_stats(SortKey.TIME).print_stats(10)
-
-to sort according to time spent within each function, and then print the
-statistics for the top ten functions.
-
-You might also try::
-
-   p.sort_stats(SortKey.FILENAME).print_stats('__init__')
-
-This will sort all the statistics by file name, and then print out statistics
-for only the class init methods (since they are spelled with ``__init__`` in
-them).  As one final example, you could try::
-
-   p.sort_stats(SortKey.TIME, SortKey.CUMULATIVE).print_stats(.5, 'init')
-
-This line sorts statistics with a primary key of time, and a secondary key of
-cumulative time, and then prints out some of the statistics. To be specific, the
-list is first culled down to 50% (re: ``.5``) of its original size, then only
-lines containing ``init`` are maintained, and that sub-sub-list is printed.
-
-If you wondered what functions called the above functions, you could now (``p``
-is still sorted according to the last criteria) do::
-
-   p.print_callers(.5, 'init')
-
-and you would get a list of callers for each of the listed functions.
-
-If you want more functionality, you're going to have to read the manual, or
-guess what the following functions do::
-
-   p.print_callees()
-   p.add('restats')
-
-Invoked as a script, the :mod:`pstats` module is a statistics browser for
-reading and examining profile dumps.  It has a simple line-oriented interface
-(implemented using :mod:`cmd`) and interactive help.

-The :class:`Stats` Class
-========================
+Differences from :mod:`!profiling.tracing`
+==========================================
 
-Analysis of the profiler data is done using the :class:`~pstats.Stats` class.
+The :mod:`!profile` module differs from :mod:`profiling.tracing` in several
+ways:
 
-.. module:: pstats
-   :synopsis: Statistics object for use with the profiler.
+**Higher overhead.** The pure Python implementation is significantly slower
+than the C implementation, making it unsuitable for profiling long-running
+programs or performance-sensitive code.
 
-.. class:: Stats(*filenames or profile, stream=sys.stdout)
+**Calibration support.** The :mod:`!profile` module supports calibration to
+compensate for profiling overhead. This is not needed in :mod:`profiling.tracing`
+because the C implementation has negligible overhead.
 
-   This class constructor creates an instance of a "statistics object" from a
-   *filename* (or list of filenames) or from a :class:`Profile` instance. Output
-   will be printed to the stream specified by *stream*.
+**Custom timers.** Both modules support custom timers, but :mod:`!profile`
+accepts timer functions that return tuples (like :func:`os.times`), while
+:mod:`profiling.tracing` requires a function returning a single number.
 
-   The file selected by the above constructor must have been created by the
-   corresponding version of :mod:`profile` or :mod:`cProfile`.  To be specific,
-   there is *no* file compatibility guaranteed with future versions of this
-   profiler, and there is no compatibility with files produced by other
-   profilers, or the same profiler run on a different operating system.  If
-   several files are provided, all the statistics for identical functions will
-   be coalesced, so that an overall view of several processes can be considered
-   in a single report.  If additional files need to be combined with data in an
-   existing :class:`~pstats.Stats` object, the :meth:`~pstats.Stats.add` method
-   can be used.
+**Subclassing.** The pure Python implementation is easier to subclass and
+extend for custom profiling behavior.
 
-   Instead of reading the profile data from a file, a :class:`cProfile.Profile`
-   or :class:`profile.Profile` object can be used as the profile data source.
-
-   :class:`Stats` objects have the following methods:
-
-   .. method:: strip_dirs()
-
-      This method for the :class:`Stats` class removes all leading path
-      information from file names.  It is very useful in reducing the size of
-      the printout to fit within (close to) 80 columns.  This method modifies
-      the object, and the stripped information is lost.  After performing a
-      strip operation, the object is considered to have its entries in a
-      "random" order, as it was just after object initialization and loading.
-      If :meth:`~pstats.Stats.strip_dirs` causes two function names to be
-      indistinguishable (they are on the same line of the same filename, and
-      have the same function name), then the statistics for these two entries
-      are accumulated into a single entry.
-
-
-   .. method:: add(*filenames)
-
-      This method of the :class:`Stats` class accumulates additional profiling
-      information into the current profiling object.  Its arguments should refer
-      to filenames created by the corresponding version of :func:`profile.run`
-      or :func:`cProfile.run`. Statistics for identically named (re: file, line,
-      name) functions are automatically accumulated into single function
-      statistics.
-
-
-   .. method:: dump_stats(filename)
-
-      Save the data loaded into the :class:`Stats` object to a file named
-      *filename*.  The file is created if it does not exist, and is overwritten
-      if it already exists.  This is equivalent to the method of the same name
-      on the :class:`profile.Profile` and :class:`cProfile.Profile` classes.
-
-
-   .. method:: sort_stats(*keys)
-
-      This method modifies the :class:`Stats` object by sorting it according to
-      the supplied criteria.  The argument can be either a string or a SortKey
-      enum identifying the basis of a sort (example: ``'time'``, ``'name'``,
-      ``SortKey.TIME`` or ``SortKey.NAME``). The SortKey enums argument have
-      advantage over the string argument in that it is more robust and less
-      error prone.
-
-      When more than one key is provided, then additional keys are used as
-      secondary criteria when there is equality in all keys selected before
-      them.  For example, ``sort_stats(SortKey.NAME, SortKey.FILE)`` will sort
-      all the entries according to their function name, and resolve all ties
-      (identical function names) by sorting by file name.
-
-      For the string argument, abbreviations can be used for any key names, as
-      long as the abbreviation is unambiguous.
-
-      The following are the valid string and SortKey:
-
-      +------------------+---------------------+----------------------+
-      | Valid String Arg | Valid enum Arg      | Meaning              |
-      +==================+=====================+======================+

-      | ``'pcalls'``     | SortKey.PCALLS      | primitive call count |
-      +------------------+---------------------+----------------------+
-      | ``'line'``       | SortKey.LINE        | line number          |
-      +------------------+---------------------+----------------------+
-      | ``'name'``       | SortKey.NAME        | function name        |

-      | ``'nfl'``        | SortKey.NFL         | name/file/line       |
-      +------------------+---------------------+----------------------+
-      | ``'stdname'``    | SortKey.STDNAME     | standard name        |
-      +------------------+---------------------+----------------------+
-      | ``'time'``       | SortKey.TIME        | internal time        |
-      +------------------+---------------------+----------------------+
-      | ``'tottime'``    | N/A                 | internal time        |
-      +------------------+---------------------+----------------------+
-
-      Note that all sorts on statistics are in descending order (placing most
-      time consuming items first), where as name, file, and line number searches
-      are in ascending order (alphabetical). The subtle distinction between
-      ``SortKey.NFL`` and ``SortKey.STDNAME`` is that the standard name is a
-      sort of the name as printed, which means that the embedded line numbers
-      get compared in an odd way.  For example, lines 3, 20, and 40 would (if
-      the file names were the same) appear in the string order 20, 3 and 40.
-      In contrast, ``SortKey.NFL`` does a numeric compare of the line numbers.
-      In fact, ``sort_stats(SortKey.NFL)`` is the same as
-      ``sort_stats(SortKey.NAME, SortKey.FILENAME, SortKey.LINE)``.
-
-      For backward-compatibility reasons, the numeric arguments ``-1``, ``0``,
-      ``1``, and ``2`` are permitted.  They are interpreted as ``'stdname'``,
-      ``'calls'``, ``'time'``, and ``'cumulative'`` respectively.  If this old
-      style format (numeric) is used, only one sort key (the numeric key) will
-      be used, and additional arguments will be silently ignored.
-
-      .. For compatibility with the old profiler.
-
-      .. versionadded:: 3.7
-         Added the SortKey enum.
-
-   .. method:: reverse_order()
-
-      This method for the :class:`Stats` class reverses the ordering of the
-      basic list within the object.  Note that by default ascending vs
-      descending order is properly selected based on the sort key of choice.
-
-      .. This method is provided primarily for compatibility with the old
-         profiler.
-
-
-   .. method:: print_stats(*restrictions)
-
-      This method for the :class:`Stats` class prints out a report as described
-      in the :func:`profile.run` definition.
-
-      The order of the printing is based on the last
-      :meth:`~pstats.Stats.sort_stats` operation done on the object (subject to
-      caveats in :meth:`~pstats.Stats.add` and
-      :meth:`~pstats.Stats.strip_dirs`).
-
-      The arguments provided (if any) can be used to limit the list down to the
-      significant entries.  Initially, the list is taken to be the complete set
-      of profiled functions.  Each restriction is either an integer (to select a
-      count of lines), or a decimal fraction between 0.0 and 1.0 inclusive (to
-      select a percentage of lines), or a string that will be interpreted as a
-      regular expression (to pattern match the standard name that is printed).
-      If several restrictions are provided, then they are applied sequentially.
-      For example::
-
-         print_stats(.1, 'foo:')
-
-      would first limit the printing to first 10% of list, and then only print
-      functions that were part of filename :file:`.\*foo:`.  In contrast, the
-      command::
-
-         print_stats('foo:', .1)
-
-      would limit the list to all functions having file names :file:`.\*foo:`,
-      and then proceed to only print the first 10% of them.
-
-
-   .. method:: print_callers(*restrictions)
-
-      This method for the :class:`Stats` class prints a list of all functions
-      that called each function in the profiled database.  The ordering is
-      identical to that provided by :meth:`~pstats.Stats.print_stats`, and the
-      definition of the restricting argument is also identical.  Each caller is
-      reported on its own line.  The format differs slightly depending on the
-      profiler that produced the stats:
-
-      * With :mod:`profile`, a number is shown in parentheses after each caller
-        to show how many times this specific call was made.  For convenience, a
-        second non-parenthesized number repeats the cumulative time spent in the
-        function at the right.
-
-      * With :mod:`cProfile`, each caller is preceded by three numbers: the
-        number of times this specific call was made, and the total and
-        cumulative times spent in the current function while it was invoked by
-        this specific caller.
-
-
-   .. method:: print_callees(*restrictions)
-
-      This method for the :class:`Stats` class prints a list of all function
-      that were called by the indicated function.  Aside from this reversal of
-      direction of calls (re: called vs was called by), the arguments and
-      ordering are identical to the :meth:`~pstats.Stats.print_callers` method.
-
-
-   .. method:: get_stats_profile()
-
-      This method returns an instance of StatsProfile, which contains a mapping
-      of function names to instances of FunctionProfile. Each FunctionProfile
-      instance holds information related to the function's profile such as how
-      long the function took to run, how many times it was called, etc...
-
-      .. versionadded:: 3.9

+Introduction to profiling
+=========================
+
+A :dfn:`profile` is a set of statistics that describes how often and for how
+long various parts of a program execute. These statistics help identify
+performance bottlenecks and guide optimization efforts. Python provides two
+fundamentally different approaches to collecting this information: statistical
+sampling and deterministic tracing.
+
+The :mod:`!profiling` package organizes Python's built-in profiling tools under
+a single namespace. It contains two submodules, each implementing a different
+profiling methodology:
+
+:mod:`profiling.sampling`
+   A statistical profiler that periodically samples the call stack. Run scripts
+   directly or attach to running processes by PID. Provides multiple output
+   formats (flame graphs, heatmaps, Firefox Profiler), GIL analysis, GC tracking,
+   and multiple profiling modes (wall-clock, CPU, GIL) with virtually no overhead.
+
+:mod:`profiling.tracing`
+   A deterministic profiler that traces every function call, return, and
+   exception event. Provides exact call counts and precise timing information,
+   capturing every invocation including very fast functions.
+
+.. note::
+
+   The profiler modules are designed to provide an execution profile for a
+   given program, not for benchmarking purposes. For benchmarking, use the
+   :mod:`timeit` module, which provides reasonably accurate timing
+   measurements. This distinction is particularly important when comparing
+   Python code against C code: deterministic profilers introduce overhead for
+   Python code but not for C-level functions, which can skew comparisons.
+
+

+
+Choosing a profiler
+===================
+
+For most performance analysis, use the statistical profiler
+(:mod:`profiling.sampling`). It has minimal overhead, works for both development
+and production, and provides rich visualization options including flame graphs,
+heatmaps, GIL analysis, and more.
+
+Use the deterministic profiler (:mod:`profiling.tracing`) when you need **exact
+call counts** and cannot afford to miss any function calls. Since it instruments
+every function call and return, it will capture even very fast functions that
+complete between sampling intervals. The tradeoff is higher overhead.
+
+The following table summarizes the key differences:

+The statistical profiler (:mod:`profiling.sampling`) is recommended for most
+performance analysis tasks. Use it the same way you would use
+:mod:`profiling.tracing`::
+
+   python -m profiling.sampling run script.py
+
+One of the main strengths of the sampling profiler is its variety of output
+formats. Beyond traditional pstats tables, it can generate interactive
+flame graphs that visualize call hierarchies, line-level source heatmaps that
+show exactly where time is spent in your code, and Firefox Profiler output for
+timeline-based analysis.
+
+The profiler also provides insight into Python interpreter behavior that
+deterministic profiling cannot capture. Use ``--mode gil`` to identify GIL
+contention in multi-threaded code, ``--mode cpu`` to measure actual CPU time
+excluding I/O waits, or inspect ``<GC>`` frames to understand garbage collection
+overhead. The ``--native`` option reveals time spent in C extensions, helping
+distinguish Python overhead from library performance.
+
+For multi-threaded applications, the ``-a`` option samples all threads
+simultaneously, showing how work is distributed. And for production debugging,
+the ``attach`` command connects to any running Python process by PID without
+requiring a restart or code changes.
+
+
+When to use deterministic tracing
+---------------------------------
+
+The deterministic profiler (:mod:`profiling.tracing`) instruments every function
+call and return. This approach has higher overhead than sampling, but guarantees
+complete coverage of program execution.
+
+The primary reason to choose deterministic tracing is when you need exact call
+counts. Statistical profiling estimates frequency based on sampling, which may
+undercount short-lived functions that complete between samples. If you need to
+verify that an optimization actually reduced the number of function calls, or
+if you want to trace the complete call graph to understand caller-callee
+relationships, deterministic tracing is the right choice.
+
+Deterministic tracing also excels at capturing functions that execute in
+microseconds. Such functions may not appear frequently enough in statistical
+samples, but deterministic tracing records every invocation regardless of
+duration.
+
+
+Quick start
+===========
+
+This section provides the minimal steps needed to start profiling. For complete
+documentation, see the dedicated pages for each profiler.
+
+
+Statistical profiling
+---------------------
+
+To profile a script, use the :mod:`profiling.sampling` module with the ``run``
+command::
+
+   python -m profiling.sampling run script.py
+   python -m profiling.sampling run -m mypackage.module
+
+This runs the script under the profiler and prints a summary of where time was
+spent. For an interactive flame graph::
+
+   python -m profiling.sampling run --flamegraph script.py
+
+To profile an already-running process, use the ``attach`` command with the
+process ID::
+
+   python -m profiling.sampling attach 1234
+
+For custom settings, specify the sampling interval (in microseconds) and
+duration (in seconds)::
+
+   python -m profiling.sampling run -i 50 -d 30 script.py
+
+
+Deterministic profiling
+-----------------------
+
+To profile a script from the command line::
+
+   python -m profiling.tracing script.py
+
+To profile a piece of code programmatically:
+
+.. code-block:: python
+
+   import profiling.tracing
+   profiling.tracing.run('my_function()')
+
+This executes the given code under the profiler and prints a summary showing
+exact function call counts and timing.
+
+
+.. _profile-output:
+
+Understanding profile output
+============================
+
+Both profilers collect function-level statistics, though they present them in
+different formats. The sampling profiler offers multiple visualizations
+(flame graphs, heatmaps, Firefox Profiler, pstats tables), while the
+deterministic profiler produces pstats-compatible output. Regardless of format,
+the underlying concepts are the same.
+
+Key profiling concepts:
+
+**Direct time** (also called *self time* or *tottime*)
+   Time spent executing code in the function itself, excluding time spent in
+   functions it called. High direct time indicates the function contains
+   expensive operations.
+
+**Cumulative time** (also called *total time* or *cumtime*)
+   Time spent in the function and all functions it called. This measures the
+   total cost of calling a function, including its entire call subtree.
+
+**Call count** (also called *ncalls* or *samples*)
+   How many times the function was called (deterministic) or sampled
+   (statistical). In deterministic profiling, this is exact. In statistical
+   profiling, it represents the number of times the function appeared in a
+   stack sample.
+
+**Primitive calls**
+   Calls that are not induced by recursion. When a function recurses, the total
+   call count includes recursive invocations, but primitive calls counts only
+   the initial entry. Displayed as ``total/primitive`` (for example, ``3/1``
+   means three total calls, one primitive).
+
+**Caller/Callee relationships**
+   Which functions called a given function (callers) and which functions it
+   called (callees). Flame graphs visualize this as nested rectangles; pstats
+   can display it via the :meth:`~pstats.Stats.print_callers` and
+   :meth:`~pstats.Stats.print_callees` methods.
+
+
+Legacy compatibility
+====================
+
+For backward compatibility, the ``cProfile`` module remains available as an
+alias to :mod:`profiling.tracing`. Existing code using ``import cProfile`` will
+continue to work without modification in all future Python versions.
+
+.. deprecated:: 3.15
+
+   The pure Python :mod:`profile` module is deprecated and will be removed in
+   Python 3.17. Use :mod:`profiling.tracing` (or its alias ``cProfile``)
+   instead. See :mod:`profile` for migration guidance.

+***************************************************

+
+The :mod:`!profiling.sampling` module, named **Tachyon**, provides statistical
+profiling of Python programs through periodic stack sampling. Tachyon can
+run scripts directly or attach to any running Python process without requiring
+code changes or restarts. Because sampling occurs externally to the target
+process, overhead is virtually zero, making Tachyon suitable for both
+development and production environments.
+
+
+What is statistical profiling?
+==============================
+
+Statistical profiling builds a picture of program behavior by periodically
+capturing snapshots of the call stack. Rather than instrumenting every function
+call and return as deterministic profilers do, Tachyon reads the call stack at
+regular intervals to record what code is currently running.
+
+This approach rests on a simple principle: functions that consume significant
+CPU time will appear frequently in the collected samples. By gathering thousands
+of samples over a profiling session, Tachyon constructs an accurate statistical
+estimate of where time is spent. The more samples collected, the
+more precise this estimate becomes.
+
+.. only:: html
+
+   The following interactive visualization demonstrates how sampling profiling
+   works. Press **Play** to watch a Python program execute, and observe how the
+   profiler periodically captures snapshots of the call stack. Adjust the
+   **sample interval** to see how sampling frequency affects the results.

+      HTML version of this documentation.
+
+
+How time is estimated
+---------------------
+
+The time values shown in Tachyon's output are **estimates derived from sample
+counts**, not direct measurements. Tachyon counts how many times each function
+appears in the collected samples, then multiplies by the sampling interval to
+estimate time.
+
+For example, with a 10 kHz sampling rate over a 10-second profile,
+Tachyon collects approximately 100,000 samples. If a function appears in 5,000
+samples (5% of total), Tachyon estimates it consumed 5% of the 10-second
+duration, or about 500 milliseconds. This is a statistical estimate, not a
+precise measurement.
+
+The accuracy of these estimates depends on sample count. With 100,000 samples,
+a function showing 5% has a margin of error of roughly ±0.5%. With only 1,000
+samples, the same 5% measurement could actually represent anywhere from 3% to
+7% of real time.
+
+This is why longer profiling durations and shorter sampling intervals produce
+more reliable results---they collect more samples. For most performance
+analysis, the default settings provide sufficient accuracy to identify
+bottlenecks and guide optimization efforts.
+
+Because sampling is statistical, results will vary slightly between runs. A
+function showing 12% in one run might show 11% or 13% in the next. This is
+normal and expected. Focus on the overall pattern rather than exact percentages,
+and don't worry about small variations between runs.
+
+
+When to use a different approach
+--------------------------------
+
+Statistical sampling is not ideal for every situation.
+
+For very short scripts that complete in under one second, the profiler may not
+collect enough samples for reliable results. Use :mod:`profiling.tracing`
+instead, or run the script in a loop to extend profiling time.
+
+When you need exact call counts, sampling cannot provide them. Sampling
+estimates frequency from snapshots, so if you need to know precisely how many
+times a function was called, use :mod:`profiling.tracing`.
+
+When comparing two implementations where the difference might be only 1-2%,
+sampling noise can obscure real differences. Use :mod:`timeit` for
+micro-benchmarks or :mod:`profiling.tracing` for precise measurements.
+
+
+The key difference from :mod:`profiling.tracing` is how measurement happens.
+A tracing profiler instruments your code, recording every function call and
+return. This provides exact call counts and precise timing but adds overhead
+to every function call. A sampling profiler, by contrast, observes the program
+from outside at fixed intervals without modifying its execution. Think of the
+difference like this: tracing is like having someone follow you and write down
+every step you take, while sampling is like taking photographs every second
+and inferring your path from those snapshots.
+
+This external observation model is what makes sampling profiling practical for
+production use. The profiled program runs at full speed because there is no
+instrumentation code running inside it, and the target process is never stopped
+or paused during sampling---Tachyon reads the call stack directly from the
+process's memory while it continues to run. You can attach to a live server,
+collect data, and detach without the application ever knowing it was observed.
+The trade-off is that very short-lived functions may be missed if they happen
+to complete between samples.
+
+Statistical profiling excels at answering the question, "Where is my program
+spending time?" It reveals hotspots and bottlenecks in production code where
+deterministic profiling overhead would be unacceptable. For exact call counts
+and complete call graphs, use :mod:`profiling.tracing` instead.

+
+
+Commands
+========
+
+Tachyon operates through several subcommands. ``run`` and ``attach`` collect
+samples over time; ``dump`` captures a single snapshot; ``replay`` converts
+binary profiles to other formats.
+
+
+The ``run`` command
+-------------------
+
+The ``run`` command launches a Python script or module and profiles it from
+startup::
+
+   python -m profiling.sampling run script.py
+   python -m profiling.sampling run -m mypackage.module
+
+When profiling a script, the profiler starts the target in a subprocess, waits
+for it to initialize, then begins collecting samples. The ``-m`` flag
+indicates that the target should be run as a module (equivalent to
+``python -m``). Arguments after the target are passed through to the
+profiled program::
+
+   python -m profiling.sampling run script.py --config settings.yaml
+
+
+The ``attach`` command
+----------------------
+
+The ``attach`` command connects to an already-running Python process by its
+process ID::
+
+   python -m profiling.sampling attach 12345
+
+This command is particularly valuable for investigating performance issues in
+production systems. The target process requires no modification and need not
+be restarted. The profiler attaches, collects samples for the specified
+duration, then detaches and produces output.
+
+::
+
+   python -m profiling.sampling attach --live 12345
+   python -m profiling.sampling attach --flamegraph -d 30 -o profile.html 12345
+
+On most systems, attaching to another process requires appropriate permissions.
+See :ref:`profiling-permissions` for platform-specific requirements.
+
+
+.. _dump-command:
+
+The ``dump`` command
+--------------------
+
+The ``dump`` command prints a single snapshot of a running process's Python
+stack and exits, similar to a traceback::
+
+   python -m profiling.sampling dump 12345
+
+Unlike ``attach``, ``dump`` does not run a sampling loop: it reads the
+stack once. This is useful for investigating hung or unresponsive
+processes, or for answering "what is this process doing right now?".
+
+The output mirrors a traceback (most recent call last) and annotates each
+thread with its current state (main thread, has GIL, on CPU, waiting for
+GIL, has exception, or idle):
+
+.. code-block:: text
+
+   Stack dump for PID 12345, thread 140735 (main thread, has GIL, on CPU; most recent call last):
+     File "server.py", line 28, in serve
+       await handle_request(req)
+     File "handler.py", line 91, in handle_request
+       result = expensive_call(req)
+
+When the target's source files are readable, ``dump`` prints the source
+line for each frame and highlights the executing expression.
+
+Like ``attach``, ``dump`` requires permission to read the target process's
+memory. See :ref:`profiling-permissions`.
+
+The ``dump`` command supports the following options:
+
+``-a``, ``--all-threads``
+   Dump every thread in the target process. Without this flag only the main
+   thread is shown.
+
+``--native``
+   Include synthetic ``<native>`` frames marking transitions into C
+   extensions or other non-Python code.
+
+``--no-gc``
+   Hide the synthetic ``<GC>`` frames that mark active garbage collection.
+
+``--opcodes``
+   Annotate each frame with the bytecode opcode the thread is currently
+   executing (for example, ``opcode=CALL_KW``). Useful for
+   instruction-level investigation, including identifying specializations
+   chosen by the adaptive interpreter.
+
+``--async-aware``
+   Reconstruct stacks across ``await`` boundaries. ``dump`` walks the task
+   graph and emits one section per task, with ``<task>`` markers separating
+   coroutines awaiting each other.
+
+``--async-mode {running,all}``
+   Controls which tasks are included when ``--async-aware`` is enabled.
+   ``running`` shows only the task currently executing on each thread;
+   ``all`` (the default for ``dump``) also includes tasks suspended on a
+   wait. ``attach``'s default for this flag is ``running``; ``dump``
+   defaults to ``all`` because a single snapshot is most useful when it
+   shows the full task graph.
+
+``--blocking``
+   Pause every thread in the target while reading its stack and resume
+   them after. Guarantees a fully consistent snapshot at the cost of
+   briefly stopping the target. Without it, ``dump`` reads memory while
+   the target keeps running, which is faster but can occasionally produce
+   a torn stack.
+
+
+.. _replay-command:
+
+The ``replay`` command
+----------------------
+
+The ``replay`` command converts binary profile files to other output formats::
+
+   python -m profiling.sampling replay profile.bin
+   python -m profiling.sampling replay --flamegraph -o profile.html profile.bin
+
+This command is useful when you have captured profiling data in binary format
+and want to analyze it later or convert it to a visualization format. Binary
+profiles can be replayed multiple times to different formats without
+re-profiling.
+
+::
+
+   # Convert binary to pstats (default, prints to stdout)
+   python -m profiling.sampling replay profile.bin
+
+   # Convert binary to flame graph
+   python -m profiling.sampling replay --flamegraph -o output.html profile.bin
+
+   # Convert binary to gecko format for Firefox Profiler
+   python -m profiling.sampling replay --gecko -o profile.json profile.bin
+
+   # Convert binary to heatmap
+   python -m profiling.sampling replay --heatmap -o my_heatmap profile.bin
+
+
+Profiling in production
+-----------------------
+
+The sampling profiler is designed for production use. It imposes no measurable
+overhead on the target process because it reads memory externally rather than
+instrumenting code. The target application continues running at full speed and
+is unaware it is being profiled.
+
+When profiling production systems, keep these guidelines in mind:
+
+Start with shorter durations (10-30 seconds) to get quick results, then extend
+if you need more statistical accuracy. By default, profiling runs until the
+target process completes, which is usually sufficient to identify major hotspots.
+
+If possible, profile during representative load rather than peak traffic.
+Profiles collected during normal operation are easier to interpret than those
+collected during unusual spikes.
+
+The profiler itself consumes some CPU on the machine where it runs (not on the
+target process). On the same machine, this is typically negligible. When
+profiling remote processes, network latency does not affect the target.
+
+Results from production may differ from development due to different data
+sizes, concurrent load, or caching effects. This is expected and is often
+exactly what you want to capture.
+
+
+.. _profiling-permissions:
+
+Platform requirements
+---------------------
+
+The profiler reads the target process's memory to capture stack traces. This
+requires elevated permissions on most operating systems.
+
+**Linux**
+
+On Linux, the profiler uses ``ptrace`` or ``process_vm_readv`` to read the
+target process's memory. This typically requires one of:
+
+- Running as root
+- Having the ``CAP_SYS_PTRACE`` capability
+- Adjusting the Yama ptrace scope: ``/proc/sys/kernel/yama/ptrace_scope``
+
+The default ptrace_scope of 1 restricts ptrace to parent processes only. To
+allow attaching to any process owned by the same user, set it to 0::
+
+   echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
+
+**macOS**
+
+On macOS, the profiler uses ``task_for_pid()`` to access the target process.
+This requires one of:
+
+- Running as root
+- The profiler binary having the ``com.apple.security.cs.debugger`` entitlement
+- System Integrity Protection (SIP) being disabled (not recommended)
+
+**Windows**
+
+On Windows, the profiler requires administrative privileges or the
+``SeDebugPrivilege`` privilege to read another process's memory.
+
+
+Version compatibility
+---------------------
+
+The profiler and target process must run the same Python minor version (for
+example, both Python 3.15). Attaching from Python 3.14 to a Python 3.15 process
+is not supported.
+
+Additional restrictions apply to pre-release Python versions: if either the
+profiler or target is running a pre-release (alpha, beta, or release candidate),
+both must run the exact same version.
+
+On free-threaded Python builds, the profiler cannot attach from a free-threaded
+build to a standard build, or vice versa.
+
+
+Sampling configuration
+======================
+
+Before exploring the various output formats and visualization options, it is
+important to understand how to configure the sampling process itself. The
+profiler offers several options that control how frequently samples are
+collected, how long profiling runs, which threads are observed, and what
+additional context is captured in each sample.
+
+The default configuration works well for most use cases:
+
+.. list-table::
+   :header-rows: 1
+   :widths: 25 75
+
+   * - Option
+     - Default
+   * - Default for ``--sampling-rate`` / ``-r``
+     - 1 kHz
+   * - Default for ``--duration`` / ``-d``
+     - Run to completion
+   * - Default for ``--all-threads`` / ``-a``
+     - Main thread only
+   * - Default for ``--native``
+     - No ``<native>`` frames (C code time attributed to caller)
+   * - Default for ``--no-gc``
+     - ``<GC>`` frames included when garbage collection is active
+   * - Default for ``--mode``
+     - Wall-clock mode (all samples recorded)
+   * - Default for ``--realtime-stats``
+     - Disabled
+   * - Default for ``--subprocesses``
+     - Disabled
+   * - Default for ``--blocking``
+     - Disabled (non-blocking sampling)
+
+
+Sampling rate and duration
+--------------------------
+
+The two most fundamental parameters are the sampling rate and duration.
+Together, these determine how many samples will be collected during a profiling
+session.
+
+The :option:`--sampling-rate` option (:option:`-r`) sets how frequently samples
+are collected. The default is 1 kHz (1,000 samples per second)::
+
+   python -m profiling.sampling run -r 20khz script.py
+
+Higher rates capture more samples and provide finer-grained data at the
+cost of slightly higher profiler CPU usage. Lower rates reduce profiler
+overhead but may miss short-lived functions. For most applications, the
+default rate provides a good balance between accuracy and overhead.
+
+The :option:`--duration` option (:option:`-d`) sets how long to profile in seconds. By
+default, profiling continues until the target process exits or is interrupted::
+
+   python -m profiling.sampling run -d 60 script.py
+
+Specifying a duration is useful when attaching to long-running processes or when
+you want to limit profiling to a specific time window. When profiling a script,
+the default behavior of running to completion is usually what you want.
+
+
+Thread selection
+----------------
+
+Python programs often use multiple threads, whether explicitly through the
+:mod:`threading` module or implicitly through libraries that manage thread
+pools.
+
+By default, the profiler samples only the main thread. The :option:`--all-threads`
+option (:option:`-a`) enables sampling of all threads in the process::
+
+   python -m profiling.sampling run -a script.py
+
+Multi-thread profiling reveals how work is distributed across threads and can
+identify threads that are blocked or starved. Each thread's samples are
+combined in the output, with the ability to filter by thread in some formats.
+This option is particularly useful when investigating concurrency issues or
+when work is distributed across a thread pool.
+
+
+.. _blocking-mode:
+
+Blocking mode
+-------------
+
+By default, Tachyon reads the target process's memory without stopping it.
+This non-blocking approach is ideal for most profiling scenarios because it
+imposes virtually zero overhead on the target application: the profiled
+program runs at full speed and is unaware it is being observed.
+
+However, non-blocking sampling can occasionally produce incomplete or
+inconsistent stack traces in applications with many generators or coroutines
+that rapidly switch between yield points, or in programs with very fast-changing
+call stacks where functions enter and exit between the start and end of a single
+stack read, resulting in reconstructed stacks that mix frames from different
+execution states or that never actually existed.
+
+For these cases, the :option:`--blocking` option stops the target process during
+each sample::
+
+   python -m profiling.sampling run --blocking script.py
+   python -m profiling.sampling attach --blocking 12345
+
+When blocking mode is enabled, the profiler suspends the target process,
+reads its stack, then resumes it. This guarantees that each captured stack
+represents a real, consistent snapshot of what the process was doing at that
+instant. The trade-off is that the target process runs slower because it is
+repeatedly paused.
+
+.. warning::
+
+   Do not use very high sample rates (low ``--interval`` values) with blocking
+   mode. Suspending and resuming a process takes time, and if the sampling
+   interval is too short, the target will spend more time stopped than running.
+   For blocking mode, intervals of 1000 microseconds (1 millisecond) or higher
+   are recommended. The default 100 microsecond interval may cause noticeable
+   slowdown in the target application.
+
+Use blocking mode only when you observe inconsistent stacks in your profiles,
+particularly with generator-heavy or coroutine-heavy code. For most
+applications, the default non-blocking mode provides accurate results with
+zero impact on the target process.
+
+
+Special frames
+--------------
+
+The profiler can inject artificial frames into the captured stacks to provide
+additional context about what the interpreter is doing at the moment each
+sample is taken. These synthetic frames help distinguish different types of
+execution that would otherwise be invisible.
+
+The :option:`--native` option adds ``<native>`` frames to indicate when Python has
+called into C code (extension modules, built-in functions, or the interpreter
+itself)::
+
+   python -m profiling.sampling run --native script.py
+
+These frames help distinguish time spent in Python code versus time spent in
+native libraries. Without this option, native code execution appears as time
+in the Python function that made the call. This is useful when optimizing
+code that makes heavy use of C extensions like NumPy or database drivers.
+
+By default, the profiler includes ``<GC>`` frames when garbage collection is
+active. The :option:`--no-gc` option suppresses these frames::
+
+   python -m profiling.sampling run --no-gc script.py
+
+GC frames help identify programs where garbage collection consumes significant
+time, which may indicate memory allocation patterns worth optimizing. If you
+see substantial time in ``<GC>`` frames, consider investigating object
+allocation rates or using object pooling.
+
+
+Opcode-aware profiling
+----------------------
+
+The :option:`--opcodes` option enables instruction-level profiling that captures
+which Python bytecode instructions are executing at each sample::
+
+   python -m profiling.sampling run --opcodes --flamegraph script.py
+
+This feature provides visibility into Python's bytecode execution, including
+adaptive specialization optimizations. When a generic instruction like
+``LOAD_ATTR`` is specialized at runtime into a more efficient variant like
+``LOAD_ATTR_INSTANCE_VALUE``, the profiler shows both the specialized name
+and the base instruction.
+
+Opcode information appears in several output formats:
+
+- **Flame graphs**: Hovering over a frame displays a tooltip with a bytecode
+  instruction breakdown, showing which opcodes consumed time in that function
+- **Heatmap**: Expandable bytecode panels per source line show instruction
+  breakdown with specialization percentages
+- **Live mode**: An opcode panel shows instruction-level statistics for the
+  selected function, accessible via keyboard navigation
+- **Gecko format**: Opcode transitions are emitted as interval markers in the
+  Firefox Profiler timeline
+
+This level of detail is particularly useful for:
+
+- Understanding the performance impact of Python's adaptive specialization
+- Identifying hot bytecode instructions that might benefit from optimization
+- Analyzing the effectiveness of different code patterns at the instruction level
+- Debugging performance issues that occur at the bytecode level
+
+The :option:`--opcodes` option is compatible with :option:`--live`, :option:`--flamegraph`,
+:option:`--heatmap`, and :option:`--gecko` formats. It requires additional memory to store
+opcode information and may slightly reduce sampling performance, but provides
+unprecedented visibility into Python's execution model.
+
+
+Real-time statistics
+--------------------
+
+The :option:`--realtime-stats` option displays sampling rate statistics during
+profiling::
+
+   python -m profiling.sampling run --realtime-stats script.py
+
+This shows the actual achieved sampling rate, which may be lower than requested
+if the profiler cannot keep up. The statistics help verify that profiling is
+working correctly and that sufficient samples are being collected. See
+:ref:`sampling-efficiency` for details on interpreting these metrics.
+
+
+Subprocess profiling
+--------------------
+
+The :option:`--subprocesses` option enables automatic profiling of subprocesses
+spawned by the target::
+
+   python -m profiling.sampling run --subprocesses script.py
+   python -m profiling.sampling attach --subprocesses 12345
+
+When enabled, the profiler monitors the target process for child process
+creation. When a new Python child process is detected, a separate profiler
+instance is automatically spawned to profile it. This is useful for
+applications that use :mod:`multiprocessing`, :mod:`subprocess`,
+:mod:`concurrent.futures` with :class:`~concurrent.futures.ProcessPoolExecutor`,
+or other process spawning mechanisms.
+
+.. code-block:: python
+   :caption: worker_pool.py
+
+   from concurrent.futures import ProcessPoolExecutor
+   import math
+
+   def compute_factorial(n):
+       total = 0
+       for i in range(50):
+           total += math.factorial(n)
+       return total
+
+   if __name__ == "__main__":
+       numbers = [5000 + i * 100 for i in range(50)]
+       with ProcessPoolExecutor(max_workers=4) as executor:
+           results = list(executor.map(compute_factorial, numbers))
+       print(f"Computed {len(results)} factorials")
+
+::
+
+   python -m profiling.sampling run --subprocesses --flamegraph worker_pool.py
+
+This produces separate flame graphs for the main process and each worker
+process: ``flamegraph_<main_pid>.html``, ``flamegraph_<worker1_pid>.html``,
+and so on.
+
+Each subprocess receives its own output file. The filename is derived from
+the specified output path (or the default) with the subprocess's process ID
+appended:
+
+- If you specify ``-o profile.html``, subprocesses produce ``profile_12345.html``,
+  ``profile_12346.html``, and so on
+- With default output, subprocesses produce files like ``flamegraph_12345.html``
+  or directories like ``heatmap_12345``
+- For pstats format (which defaults to stdout), subprocesses produce files like
+  ``profile_12345.pstats``
+
+The subprocess profilers inherit most sampling options from the parent (sampling
+rate, duration, thread selection, native frames, GC frames, async-aware mode,
+and output format). All Python descendant processes are profiled recursively,
+including grandchildren and further descendants.
+
+Subprocess detection works by periodically scanning for new descendants of
+the target process and checking whether each new process is a Python process
+by probing the process memory for Python runtime structures. Non-Python
+subprocesses (such as shell commands or external tools) are ignored.
+
+There is a limit of 100 concurrent subprocess profilers to prevent resource
+exhaustion in programs that spawn many processes. If this limit is reached,
+additional subprocesses are not profiled and a warning is printed.
+
+The :option:`--subprocesses` option is incompatible with :option:`--live` mode
+because live mode uses an interactive terminal interface that cannot
+accommodate multiple concurrent profiler displays.
+
+
+.. _sampling-efficiency:
+
+Sampling efficiency
+-------------------
+
+Sampling efficiency metrics help assess the quality of the collected data.
+These metrics appear in the profiler's terminal output and in the flame graph
+sidebar.
+
+**Sampling efficiency** is the percentage of sample attempts that succeeded.
+Each sample attempt reads the target process's call stack from memory. An
+attempt can fail if the process is in an inconsistent state at the moment of
+reading, such as during a context switch or while the interpreter is updating
+its internal structures. A low efficiency may indicate that the profiler could
+not keep up with the requested sampling rate, often due to system load or an
+overly aggressive interval setting.
+
+**Missed samples** is the percentage of expected samples that were not
+collected. Based on the configured interval and duration, the profiler expects
+to collect a certain number of samples. Some samples may be missed if the
+profiler falls behind schedule, for example when the system is under heavy
+load. A small percentage of missed samples is normal and does not significantly
+affect the statistical accuracy of the profile.
+
+Both metrics are informational. Even with some failed attempts or missed
+samples, the profile remains statistically valid as long as enough samples
+were collected. The profiler reports the actual number of samples captured,
+which you can use to judge whether the data is sufficient for your analysis.
+
+
+Profiling modes
+===============
+
+The sampling profiler supports four modes that control which samples are
+recorded. The mode determines what the profile measures: total elapsed time,
+CPU execution time, time spent holding the global interpreter lock, or
+exception handling.
+
+
+Wall-clock mode
+---------------
+
+Wall-clock mode (:option:`--mode`\ ``=wall``) captures all samples regardless of what the
+thread is doing. This is the default mode and provides a complete picture of
+where time passes during program execution::
+
+   python -m profiling.sampling run --mode=wall script.py
+
+In wall-clock mode, samples are recorded whether the thread is actively
+executing Python code, waiting for I/O, blocked on a lock, or sleeping.
+This makes wall-clock profiling ideal for understanding the overall time
+distribution in your program, including time spent waiting.
+
+If your program spends significant time in I/O operations, network calls, or
+sleep, wall-clock mode will show these waits as time attributed to the calling
+function. This is often exactly what you want when optimizing end-to-end
+latency.
+
+
+CPU mode
+--------
+
+CPU mode (:option:`--mode`\ ``=cpu``) records samples only when the thread is actually
+executing on a CPU core::
+
+   python -m profiling.sampling run --mode=cpu script.py
+
+Samples taken while the thread is sleeping, blocked on I/O, or waiting for
+a lock are discarded. The resulting profile shows where CPU cycles are consumed,
+filtering out idle time.
+
+CPU mode is useful when you want to focus on computational hotspots without
+being distracted by I/O waits. If your program alternates between computation
+and network calls, CPU mode reveals which computational sections are most
+expensive.
+
+
+Comparing wall-clock and CPU profiles
+-------------------------------------
+
+Running both wall-clock and CPU mode profiles can reveal whether a function's
+time is spent computing or waiting.
+
+If a function appears prominently in both profiles, it is a true computational
+hotspot---actively using the CPU. Optimization should focus on algorithmic
+improvements or more efficient code.
+
+If a function is high in wall-clock mode but low or absent in CPU mode, it is
+I/O-bound or waiting. The function spends most of its time waiting for network,
+disk, locks, or sleep. CPU optimization won't help here; consider async I/O,
+connection pooling, or reducing wait time instead.
+
+.. code-block:: python
+
+   import time
+
+   def do_sleep():
+       time.sleep(2)
+
+   def do_compute():
+       sum(i**2 for i in range(1000000))
+
+   if __name__ == "__main__":
+       do_sleep()
+       do_compute()
+
+::
+
+   python -m profiling.sampling run --mode=wall script.py  # do_sleep ~98%, do_compute ~1%
+   python -m profiling.sampling run --mode=cpu script.py   # do_sleep absent, do_compute dominates
+
+
+GIL mode
+--------
+
+GIL mode (:option:`--mode`\ ``=gil``) records samples only when the thread holds Python's
+global interpreter lock::
+
+   python -m profiling.sampling run --mode=gil script.py
+
+The GIL is held only while executing Python bytecode. When Python calls into
+C extensions, performs I/O operations, or executes native code, the GIL is
+typically released. This means GIL mode effectively measures time spent
+running Python code specifically, filtering out time in native libraries.
+
+In multi-threaded programs, GIL mode reveals which code is preventing other
+threads from running Python bytecode. Since only one thread can hold the GIL
+at a time, functions that appear frequently in GIL mode profiles are
+monopolizing the interpreter.
+
+GIL mode helps answer questions like "which functions are monopolizing the
+GIL?" and "why are my other threads starving?" It can also be useful in
+single-threaded programs to distinguish Python execution time from time spent
+in C extensions or I/O.
+
+.. code-block:: python
+
+   import hashlib
+
+   def hash_work():
+       # C extension - releases GIL during computation
+       for _ in range(200):
+           hashlib.sha256(b"data" * 250000).hexdigest()
+
+   def python_work():
+       # Pure Python - holds GIL during computation
+       for _ in range(3):
+           sum(i**2 for i in range(1000000))
+
+   if __name__ == "__main__":
+       hash_work()
+       python_work()
+
+::
+
+   python -m profiling.sampling run --mode=cpu script.py  # hash_work ~42%, python_work ~38%
+   python -m profiling.sampling run --mode=gil script.py  # hash_work ~5%, python_work ~60%
+
+
+Exception mode
+--------------
+
+Exception mode (``--mode=exception``) records samples only when a thread has
+an active exception::
+
+   python -m profiling.sampling run --mode=exception script.py
+
+Samples are recorded in two situations: when an exception is being propagated
+up the call stack (after ``raise`` but before being caught), or when code is
+executing inside an ``except`` block where exception information is still
+present in the thread state.
+
+The following example illustrates which code regions are captured:
+
+.. code-block:: python
+
+   def example():
+       try:
+           raise ValueError("error")    # Captured: exception being raised
+       except ValueError:
+           process_error()              # Captured: inside except block
+       finally:
+           cleanup()                    # NOT captured: exception already handled
+
+   def example_propagating():
+       try:
+           try:
+               raise ValueError("error")
+           finally:
+               cleanup()                # Captured: exception propagating through
+       except ValueError:
+           pass
+
+   def example_no_exception():
+       try:
+           do_work()
+       finally:
+           cleanup()                    # NOT captured: no exception involved
+
+Note that ``finally`` blocks are only captured when an exception is actively
+propagating through them. Once an ``except`` block finishes executing, Python
+clears the exception information before running any subsequent ``finally``
+block. Similarly, ``finally`` blocks that run during normal execution (when no
+exception was raised) are not captured because no exception state is present.
+
+This mode is useful for understanding where your program spends time handling
+errors. Exception handling can be a significant source of overhead in code
+that uses exceptions for flow control (such as ``StopIteration`` in iterators)
+or in applications that process many error conditions (such as network servers
+handling connection failures).
+
+Exception mode helps answer questions like "how much time is spent handling
+exceptions?" and "which exception handlers are the most expensive?" It can
+reveal hidden performance costs in code that catches and processes many
+exceptions, even when those exceptions are handled gracefully. For example,
+if a parsing library uses exceptions internally to signal format errors, this
+mode will capture time spent in those handlers even if the calling code never
+sees the exceptions.
+
+
+Output formats
+==============
+
+The profiler produces output in several formats, each suited to different
+analysis workflows. The format is selected with a command-line flag, and
+output goes to stdout, a file, or a directory depending on the format.
+
+
+pstats format
+-------------
+
+The pstats format (:option:`--pstats`) produces a text table similar to what
+deterministic profilers generate. This is the default output format::
+
+   python -m profiling.sampling run script.py
+   python -m profiling.sampling run --pstats script.py
+
+.. figure:: tachyon-pstats.png
+   :alt: Tachyon pstats terminal output
+   :align: center
+   :width: 100%
+
+   The pstats format displays profiling results in a color-coded table showing
+   function hotspots, sample counts, and timing estimates.
+
+Output appears on stdout by default::
+
+   Profile Stats (Mode: wall):
+        nsamples  sample%    tottime (ms)  cumul%   cumtime (ms)  filename:lineno(function)
+          234/892    11.7%       234.00     44.6%       892.00    server.py:145(handle_request)
+          156/156     7.8%       156.00      7.8%       156.00    <built-in>:0(socket.recv)
+           98/421     4.9%        98.00     21.1%       421.00    parser.py:67(parse_message)
+
+The columns show sampling counts and estimated times:
+
+- **nsamples**: Displayed as ``direct/cumulative`` (for example, ``10/50``).
+  Direct samples are when the function was at the top of the stack, actively
+  executing. Cumulative samples are when the function appeared anywhere on the
+  stack, including when it was waiting for functions it called. If a function
+  shows ``10/50``, it was directly executing in 10 samples and was on the call
+  stack in 50 samples total.
+
+- **sample%** and **cumul%**: Percentages of total samples for direct and
+  cumulative counts respectively.
+
+- **tottime** and **cumtime**: Estimated wall-clock time based on sample counts
+  and the profiling duration. Time units are selected automatically based on
+  the magnitude: seconds for large values, milliseconds for moderate values,
+  or microseconds for small values.
+
+The output includes a legend explaining each column and a summary of
+interesting functions that highlights:
+
+- **Hot spots**: Functions with high direct/cumulative sample ratio (ratio
+  close to 1.0). These functions spend most of their time executing their own
+  code rather than waiting for callees. High ratios indicate where CPU time
+  is actually consumed.
+
+- **Indirect calls**: Functions with large differences between cumulative and
+  direct samples. These are orchestration functions that delegate work to
+  other functions. They appear frequently on the stack but rarely at the top.
+
+- **Call magnification**: Functions where cumulative samples far exceed direct
+  samples (high cumulative/direct multiplier). These are frequently-nested
+  functions that appear deep in many call chains.
+
+Use :option:`--no-summary` to suppress both the legend and summary sections.
+
+To save pstats output to a binary file instead of stdout::
+
+   python -m profiling.sampling run -o profile.pstats script.py
+
+The pstats format supports several options for controlling the display.
+The :option:`--sort` option determines the column used for ordering results::
+
+   python -m profiling.sampling run --sort=tottime script.py
+   python -m profiling.sampling run --sort=cumtime script.py
+   python -m profiling.sampling run --sort=nsamples script.py
+
+The :option:`--limit` option restricts output to the top N entries::
+
+   python -m profiling.sampling run --limit=30 script.py
+
+The :option:`--no-summary` option suppresses the header summary that precedes the
+statistics table.
+
+
+Collapsed stacks format
+-----------------------
+
+Collapsed stacks format (:option:`--collapsed`) produces one line per unique call
+stack, with a count of how many times that stack was sampled::
+
+   python -m profiling.sampling run --collapsed script.py
+
+The output looks like:
+
+.. code-block:: text
+
+   main;process_data;parse_json;decode_utf8 42
+   main;process_data;parse_json 156
+   main;handle_request;send_response 89
+
+Each line contains semicolon-separated function names representing the call
+stack from bottom to top, followed by a space and the sample count. This
+format is designed for compatibility with external flame graph tools,
+particularly Brendan Gregg's ``flamegraph.pl`` script.
+
+To generate a flame graph from collapsed stacks::
+
+   python -m profiling.sampling run --collapsed script.py > stacks.txt
+   flamegraph.pl stacks.txt > profile.svg
+
+The resulting SVG can be viewed in any web browser and provides an interactive
+visualization where you can click to zoom into specific call paths.
+
+
+Flame graph format
+------------------
+
+Flame graph format (:option:`--flamegraph`) produces a self-contained HTML file with
+an interactive flame graph visualization::
+
+   python -m profiling.sampling run --flamegraph script.py
+   python -m profiling.sampling run --flamegraph -o profile.html script.py
+
+.. figure:: tachyon-flamegraph.png
+   :alt: Tachyon interactive flame graph
+   :align: center
+   :width: 100%
+
+   The flame graph visualization shows call stacks as nested rectangles, with
+   width proportional to time spent. The sidebar displays runtime statistics,
+   GIL metrics, and hotspot functions.
+
+.. only:: html
+
+   `Try the interactive example <../_static/tachyon-example-flamegraph.html>`__!
+
+If no output file is specified, the profiler generates a filename based on
+the process ID (for example, ``flamegraph.12345.html``).
+
+The generated HTML file requires no external dependencies and can be opened
+directly in a web browser. The visualization displays call stacks as nested
+rectangles, with width proportional to time spent. Hovering over a rectangle
+shows details about that function including source code context, and clicking
+zooms into that portion of the call tree.
+
+The flame graph interface includes:
+
+- A sidebar showing profile summary, thread statistics, sampling efficiency
+  metrics (see :ref:`sampling-efficiency`), and top hotspot functions
+- Search functionality supporting both function name matching and
+  ``file.py:42`` line patterns
+- Per-thread filtering via dropdown
+- Dark/light theme toggle (preference saved across sessions)
+- SVG export for saving the current view
+
+The thread statistics section shows runtime behavior metrics:
+
+- **GIL Held**: percentage of samples where a thread held the global interpreter
+  lock (actively running Python code)
+- **GIL Released**: percentage of samples where no thread held the GIL
+- **Waiting GIL**: percentage of samples where a thread was waiting to acquire
+  the GIL
+- **GC**: percentage of samples during garbage collection
+
+These statistics help identify GIL contention and understand how time is
+distributed between Python execution, native code, and waiting.
+
+Flame graphs are particularly effective for identifying deep call stacks and
+understanding the hierarchical structure of time consumption. Wide rectangles
+at the top indicate functions that consume significant time either directly
+or through their callees.
+
+
+Differential flame graphs
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Differential flame graphs compare two profiling runs to highlight where
+performance changed. This helps identify regressions introduced by code changes
+and validate that optimizations achieved their intended effect::
+
+   # Capture baseline profile
+   python -m profiling.sampling run --binary -o baseline.bin script.py
+
+   # After modifying code, generate differential flamegraph
+   python -m profiling.sampling run --diff-flamegraph baseline.bin -o diff.html script.py
+
+The visualization draws the current profile with frame widths showing current
+time consumption, then applies color to indicate how each function changed
+relative to the baseline.
+
+**Color coding**:
+
+- **Red**: Functions consuming more time (regressions). Lighter shades indicate
+  modest increases, while darker shades show severe regressions.
+
+- **Blue**: Functions consuming less time (improvements). Lighter shades for
+  modest reductions, darker shades for significant speedups.
+
+- **Gray**: Minimal or no change.
+
+- **Purple**: New functions not present in the baseline.
+
+Frame colors indicate changes in **direct time** (time when the function was at
+the top of the stack, actively executing), not cumulative time including callees.
+Hovering over a frame shows comparison details including baseline time, current
+time, and the percentage change.
+
+Some call paths may disappear entirely between profiles. These are called
+**elided stacks** and occur when optimizations eliminate code paths or certain
+branches stop executing. If elided stacks are present, an elided toggle appears
+allowing you to switch between the main differential view and an elided-only
+view that shows just the removed paths (colored purple).
+
+
+Gecko format
+------------
+
+Gecko format (:option:`--gecko`) produces JSON output compatible with the Firefox
+Profiler::
+
+   python -m profiling.sampling run --gecko script.py
+   python -m profiling.sampling run --gecko -o profile.json script.py
+
+The `Firefox Profiler <https://profiler.firefox.com>`__ is a sophisticated
+web-based tool originally built for profiling Firefox itself. It provides
+features beyond basic flame graphs, including a timeline view, call tree
+exploration, and marker visualization. See the
+`Firefox Profiler documentation <https://profiler.firefox.com/docs/#/>`__ for
+detailed usage instructions.
+
+To use the output, open the Firefox Profiler in your browser and load the
+JSON file. The profiler runs entirely client-side, so your profiling data
+never leaves your machine.
+
+Gecko format automatically collects additional metadata about GIL state and
+CPU activity, enabling analysis features specific to Python's threading model.
+The profiler emits interval markers that appear as colored bands in the
+Firefox Profiler timeline:
+
+- **GIL markers**: show when threads hold or release the global interpreter lock
+- **CPU markers**: show when threads are executing on CPU versus idle
+- **Code type markers**: distinguish Python code from native (C extension) code
+- **GC markers**: indicate garbage collection activity
+
+For this reason, the :option:`--mode` option is not available with Gecko format;
+all relevant data is captured automatically.
+
+.. figure:: tachyon-gecko-calltree.png
+   :alt: Firefox Profiler Call Tree view
+   :align: center
+   :width: 100%
+
+   The Call Tree view shows the complete call hierarchy with sample counts
+   and percentages. The sidebar displays detailed statistics for the
+   selected function including running time and sample distribution.
+
+.. figure:: tachyon-gecko-flamegraph.png
+   :alt: Firefox Profiler Flame Graph view
+   :align: center
+   :width: 100%
+
+   The Flame Graph visualization shows call stacks as nested rectangles.
+   Functions names are visible in the call hierarchy.
+
+.. figure:: tachyon-gecko-opcodes.png
+   :alt: Firefox Profiler Marker Chart with opcodes
+   :align: center
+   :width: 100%
+
+   The Marker Chart displays interval markers including CPU state, GIL
+   status, and opcodes. With ``--opcodes`` enabled, bytecode instructions
+   like ``BINARY_OP_ADD_FLOAT``, ``CALL_PY_EXACT_ARGS``, and
+   ``CALL_LIST_APPEND`` appear as markers showing execution over time.
+
+
+Heatmap format
+--------------
+
+Heatmap format (:option:`--heatmap`) generates an interactive HTML visualization
+showing sample counts at the source line level::
+
+   python -m profiling.sampling run --heatmap script.py
+   python -m profiling.sampling run --heatmap -o my_heatmap script.py
+
+.. figure:: tachyon-heatmap.png
+   :alt: Tachyon heatmap visualization
+   :align: center
+   :width: 100%
+
+   The heatmap overlays sample counts directly on your source code. Lines are
+   color-coded from cool (few samples) to hot (many samples). Navigation
+   buttons (▲▼) let you jump between callers and callees.
+
+Unlike other formats that produce a single file, heatmap output creates a
+directory containing HTML files for each profiled source file. If no output
+path is specified, the directory is named ``heatmap_PID``.
+
+The heatmap visualization displays your source code with a color gradient
+indicating how many samples were collected at each line. Hot lines (many
+samples) appear in warm colors, while cold lines (few or no samples) appear
+in cool colors. This view helps pinpoint exactly which lines of code are
+responsible for time consumption.
+
+The heatmap interface provides several interactive features:
+
+- **Coloring modes**: toggle between "Self Time" (direct execution) and
+  "Total Time" (cumulative, including time in called functions)
+- **Cold code filtering**: show all lines or only lines with samples
+- **Call graph navigation**: each line shows navigation buttons (▲ for callers,
+  ▼ for callees) that let you trace execution paths through your code. When
+  multiple functions called or were called from a line, a menu appears showing
+  all options with their sample counts.
+- **Scroll minimap**: a vertical overview showing the heat distribution across
+  the entire file
+- **Hierarchical index**: files organized by type (stdlib, site-packages,
+  project) with aggregate sample counts per folder
+- **Dark/light theme**: toggle with preference saved across sessions
+- **Line linking**: click line numbers to create shareable URLs
+
+When opcode-level profiling is enabled with :option:`--opcodes`, each hot line
+can be expanded to show which bytecode instructions consumed time:
+
+.. figure:: tachyon-heatmap-with-opcodes.png
+   :alt: Heatmap with expanded bytecode panel
+   :align: center
+   :width: 100%
+
+   Expanding a hot line reveals the bytecode instructions executed, including
+   specialized variants. The panel shows sample counts per instruction and the
+   overall specialization percentage for the line.

+Heatmaps are especially useful when you know which file contains a performance
+issue but need to identify the specific lines. Many developers prefer this
+format because it maps directly to their source code, making it easy to read
+and navigate. For smaller scripts and focused analysis, heatmaps provide an
+intuitive view that shows exactly where time is spent without requiring
+interpretation of hierarchical visualizations.
+
+
+Binary format
+-------------
+
+Binary format (:option:`--binary`) produces a compact binary file for efficient
+storage of profiling data::
+
+   python -m profiling.sampling run --binary -o profile.bin script.py
+   python -m profiling.sampling attach --binary -o profile.bin 12345
+
+The :option:`--compression` option controls data compression:
+
+- ``auto`` (default): Use zstd compression if available, otherwise no
+  compression
+- ``zstd``: Force zstd compression (requires :mod:`compression.zstd` support)
+- ``none``: Disable compression
+
+::
+
+   python -m profiling.sampling run --binary --compression=zstd -o profile.bin script.py
+
+To analyze binary profiles, use the :ref:`replay-command` to convert them to
+other formats like flame graphs or pstats output.
+
+
+Record and replay workflow
+==========================
+
+The binary format combined with the replay command enables a record-and-replay
+workflow that separates data capture from analysis. Rather than generating
+visualizations during profiling, you capture raw data to a compact binary file
+and convert it to different formats later.
+
+This approach has three main benefits:
+
+- Sampling runs faster because the work of building data structures for
+  visualization is deferred until replay.
+- A single binary capture can be converted to multiple output formats
+  without re-profiling: pstats for a quick overview, flame graph for visual
+  exploration, heatmap for line-level detail.
+- Binary files are compact and easy to share with colleagues who can convert
+  them to their preferred format.
+
+A typical workflow::
+
+   # Capture profile in production or during tests
+   python -m profiling.sampling attach --binary -o profile.bin 12345
+
+   # Later, analyze with different formats
+   python -m profiling.sampling replay profile.bin
+   python -m profiling.sampling replay --flamegraph -o profile.html profile.bin
+   python -m profiling.sampling replay --heatmap -o heatmap profile.bin
+
+
+Live mode
+=========
+
+Live mode (:option:`--live`) provides a terminal-based real-time view of profiling
+data, similar to the ``top`` command for system processes::
+
+   python -m profiling.sampling run --live script.py
+   python -m profiling.sampling attach --live 12345
+
+.. only:: not latex
+
+   .. figure:: tachyon-live-mode-2.gif
+      :alt: Tachyon live mode showing all threads
+      :align: center
+      :width: 100%
+
+   Live mode displays real-time profiling statistics, showing combined
+   data from multiple threads in a multi-threaded application.
+
+The display updates continuously as new samples arrive, showing the current
+hottest functions. This mode requires the :mod:`curses` module, which is
+available on Unix-like systems but not on Windows. The terminal must be at
+least 60 columns wide and 12 lines tall; larger terminals display more columns.
+
+The header displays the top 3 hottest functions, sampling efficiency metrics,
+and thread status statistics (GIL held percentage, CPU usage, GC time). The
+main table shows function statistics with the currently sorted column indicated
+by an arrow (▼).
+
+When :option:`--opcodes` is enabled, an additional opcode panel appears below the
+main table, showing instruction-level statistics for the currently selected
+function. This panel displays which bytecode instructions are executing most
+frequently, including specialized variants and their base opcodes.
+
+.. only:: not latex
+
+   .. figure:: tachyon-live-mode-1.gif
+      :alt: Tachyon live mode with opcode panel
+      :align: center
+      :width: 100%
+
+   Live mode with ``--opcodes`` enabled shows an opcode panel with a bytecode
+   instruction breakdown for the selected function.
+
+
+Keyboard commands
+-----------------
+
+Within live mode, keyboard commands control the display:
+
+:kbd:`q`
+   Quit the profiler and return to the shell.
+
+:kbd:`s` / :kbd:`S`
+   Cycle through sort orders forward/backward (sample count, percentage,
+   total time, cumulative percentage, cumulative time).
+
+:kbd:`p`
+   Pause or resume display updates. Sampling continues in the background
+   while the display is paused, so you can freeze the view to examine results
+   without stopping data collection.
+
+:kbd:`r`
+   Reset all statistics and start fresh. This is disabled after profiling
+   finishes to prevent accidental data loss.
+
+:kbd:`/`
+   Enter filter mode to search for functions by name. The filter uses
+   case-insensitive substring matching against the filename and function name.
+   Type a pattern and press Enter to apply, or Escape to cancel. Glob patterns
+   and regular expressions are not supported.
+
+:kbd:`c`
+   Clear the current filter and show all functions again.
+
+:kbd:`t`
+   Toggle between viewing all threads combined or per-thread statistics.
+   In per-thread mode, a thread counter (for example, ``1/4``) appears showing
+   your position among the available threads.
+
+:kbd:`←` :kbd:`→` or :kbd:`↑` :kbd:`↓`
+   In per-thread view, navigate between threads. Navigation wraps around
+   from the last thread to the first and vice versa.
+
+:kbd:`+` / :kbd:`-`
+   Increase or decrease the display refresh rate. The range is 0.05 seconds
+   (20 Hz, very responsive) to 1.0 second (1 Hz, lower overhead). Faster refresh
+   rates use more CPU. The default is 0.1 seconds (10 Hz).
+
+:kbd:`x`
+   Toggle trend indicators that show whether functions are becoming hotter
+   or cooler over time. When enabled, increasing metrics appear in green and
+   decreasing metrics appear in red, comparing each update to the previous one.
+
+:kbd:`h` or :kbd:`?`
+   Show the help screen with all available commands.
+
+:kbd:`j` / :kbd:`k` (or :kbd:`Up` / :kbd:`Down`)
+   Navigate through opcode entries in the opcode panel (when ``--opcodes`` is
+   enabled). These keys scroll through the instruction-level statistics for the
+   currently selected function.
+
+When profiling finishes (duration expires or target process exits), the display
+shows a "PROFILING COMPLETE" banner and freezes the final results. You can
+still navigate, sort, and filter the results before pressing :kbd:`q` to exit.
+
+Live mode is incompatible with output format options (:option:`--collapsed`,
+:option:`--flamegraph`, and so on) because it uses an interactive terminal
+interface rather than producing file output.
+
+
+Async-aware profiling
+=====================
+
+For programs using :mod:`asyncio`, the profiler offers async-aware mode
+(:option:`--async-aware`) that reconstructs call stacks based on the task structure
+rather than the raw Python frames::
+
+   python -m profiling.sampling run --async-aware async_script.py
+
+Standard profiling of async code can be confusing because the physical call
+stack often shows event loop internals rather than the logical flow of your
+coroutines. Async-aware mode addresses this by tracking which task is running
+and presenting stacks that reflect the ``await`` chain.
+
+.. code-block:: python
+
+   import asyncio
+
+   async def fetch(url):
+       await asyncio.sleep(0.1)
+       return url
+
+   async def main():
+       for _ in range(50):
+           await asyncio.gather(fetch("a"), fetch("b"), fetch("c"))
+
+   if __name__ == "__main__":
+       asyncio.run(main())
+
+::
+
+   python -m profiling.sampling run --async-aware --flamegraph -o out.html script.py
+
+.. note::
+
+   Async-aware profiling requires the target process to have the :mod:`asyncio`
+   module loaded. If you profile a script before it imports asyncio, async-aware
+   mode will not be able to capture task information.
+
+
+Async modes
+-----------
+
+The :option:`--async-mode` option controls which tasks appear in the profile::
+
+   python -m profiling.sampling run --async-aware --async-mode=running async_script.py
+   python -m profiling.sampling run --async-aware --async-mode=all async_script.py
+
+With :option:`--async-mode`\ ``=running`` (the default), only the task currently executing
+on the CPU is profiled. This shows where your program is actively spending time
+and is the typical choice for performance analysis.
+
+With :option:`--async-mode`\ ``=all``, tasks that are suspended (awaiting I/O, locks, or
+other tasks) are also included. This mode is useful for understanding what your
+program is waiting on, but produces larger profiles since every suspended task
+appears in each sample.
+
+
+Task markers and stack reconstruction
+-------------------------------------
+
+In async-aware profiles, you will see ``<task>`` frames that mark boundaries
+between asyncio tasks. These are synthetic frames inserted by the profiler to
+show the task structure. The task name appears as the function name in these
+frames.
+
+When a task awaits another task, the profiler reconstructs the logical call
+chain by following the ``await`` relationships. Only "leaf" tasks (tasks that
+no other task is currently awaiting) generate their own stack entries. Tasks
+being awaited by other tasks appear as part of their awaiter's stack instead.
+
+If a task has multiple awaiters (a diamond pattern in the task graph), the
+profiler deterministically selects one parent and annotates the task marker
+with the number of parents, for example ``MyTask (2 parents)``. This indicates
+that alternate execution paths exist but are not shown in this particular stack.
+
+
+Option restrictions
+-------------------
+
+Async-aware mode uses a different stack reconstruction mechanism and is
+incompatible with: :option:`--native`, :option:`--no-gc`, :option:`--all-threads`, and
+:option:`--mode`\ ``=cpu`` or :option:`--mode`\ ``=gil``.
+
+

+****************************************************

+.. module:: profiling.tracing
+   :synopsis: Deterministic tracing profiler for Python programs.
+
+.. module:: cProfile
+   :synopsis: Alias for profiling.tracing (backward compatibility).
+   :noindex:
+
+.. versionadded:: 3.15
+
+**Source code:** :source:`Lib/profiling/tracing/`
+
+--------------
+
+The :mod:`!profiling.tracing` module provides deterministic profiling of Python
+programs. It monitors every function call, function return, and exception event,
+recording precise timing for each. This approach provides exact call counts and
+complete visibility into program execution, making it ideal for development and
+testing scenarios.
+
+.. note::
+
+   This module is also available as ``cProfile`` for backward compatibility.
+   The ``cProfile`` name will continue to work in all future Python versions.
+   Use whichever import style suits your codebase::
+
+      # Preferred (new style)
+      import profiling.tracing
+      profiling.tracing.run('my_function()')
+
+      # Also works (backward compatible)
+      import cProfile
+      cProfile.run('my_function()')
+
+
+What is deterministic profiling?
+================================
+
+:dfn:`Deterministic profiling` captures every function call, function return,
+and exception event during program execution. The profiler measures the precise
+time intervals between these events, providing exact statistics about how the
+program behaves.
+
+In contrast to :ref:`statistical profiling <profiling-sampling>`, which samples
+the call stack periodically to estimate where time is spent, deterministic
+profiling records every event. This means you get exact call counts rather than
+statistical approximations. The trade-off is that instrumenting every event
+introduces overhead that can slow down program execution.
+
+Python's interpreted nature makes deterministic profiling practical. The
+interpreter already dispatches events for function calls and returns, so the
+profiler can hook into this mechanism without requiring code modification. The
+overhead tends to be moderate relative to the inherent cost of interpretation,
+making deterministic profiling suitable for most development workflows.
+
+Deterministic profiling helps answer questions like:
+
+- How many times was this function called?
+- What is the complete call graph of my program?
+- Which functions are called by a particular function?
+- Are there unexpected function calls happening?
+
+Call count statistics can identify bugs (surprising counts) and inline
+expansion opportunities (high call counts). Internal time statistics reveal
+"hot loops" that warrant optimization. Cumulative time statistics help identify
+algorithmic inefficiencies. The handling of cumulative times in this profiler
+allows direct comparison of recursive and iterative implementations.
+
+
+.. _profiling-tracing-cli:
+
+Command-line interface
+======================
+
+.. program:: profiling.tracing
+
+The :mod:`!profiling.tracing` module can be invoked as a script to profile
+another script or module:
+
+.. code-block:: shell-session
+
+   python -m profiling.tracing [-o output_file] [-s sort_order] (-m module | script.py)
+
+This runs the specified script or module under the profiler and prints the
+results to standard output (or saves them to a file).
+
+.. option:: -o <output_file>
+
+   Write the profile results to a file instead of standard output. The output
+   file can be read by the :mod:`pstats` module for later analysis.
+
+.. option:: -s <sort_order>
+
+   Sort the output by the specified key. This accepts any of the sort keys
+   recognized by :meth:`pstats.Stats.sort_stats`, such as ``cumulative``,
+   ``time``, ``calls``, or ``name``. This option only applies when
+   :option:`-o <profiling.tracing -o>` is not specified.
+
+.. option:: -m <module>
+
+   Profile a module instead of a script. The module is located using the
+   standard import mechanism.
+
+   .. versionadded:: 3.7
+      The ``-m`` option for ``cProfile``.
+
+   .. versionadded:: 3.8
+      The ``-m`` option for :mod:`profile`.
+
+
+Programmatic usage examples
+===========================
+
+For more control over profiling, use the module's functions and classes
+directly.
+
+
+Basic profiling
+---------------
+
+The simplest approach uses the :func:`!run` function::
+
+   import profiling.tracing
+   profiling.tracing.run('my_function()')
+
+This profiles the given code string and prints a summary to standard output.
+To save results for later analysis::
+
+   profiling.tracing.run('my_function()', 'output.prof')
+
+
+Using the :class:`!Profile` class
+---------------------------------
+
+The :class:`!Profile` class provides fine-grained control::
+
+   import profiling.tracing
+   import pstats
+   from io import StringIO
+
+   pr = profiling.tracing.Profile()
+   pr.enable()
+   # ... code to profile ...
+   pr.disable()
+
+   # Print results
+   s = StringIO()
+   ps = pstats.Stats(pr, stream=s).sort_stats(pstats.SortKey.CUMULATIVE)
+   ps.print_stats()
+   print(s.getvalue())
+
+The :class:`!Profile` class also works as a context manager::
+
+   import profiling.tracing
+
+   with profiling.tracing.Profile() as pr:
+       # ... code to profile ...
+
+   pr.print_stats()
+
+
+Module reference
+================
+
+.. currentmodule:: profiling.tracing
+
+.. function:: run(command, filename=None, sort=-1)
+
+   Profile execution of a command and print or save the results.
+
+   This function executes the *command* string using :func:`exec` in the
+   ``__main__`` module's namespace::
+
+      exec(command, __main__.__dict__, __main__.__dict__)
+
+   If *filename* is not provided, the function creates a :class:`pstats.Stats`
+   instance and prints a summary to standard output. If *filename* is
+   provided, the raw profile data is saved to that file for later analysis
+   with :mod:`pstats`.
+
+   The *sort* argument specifies the sort order for printed output, accepting
+   any value recognized by :meth:`pstats.Stats.sort_stats`.
+
+
+.. function:: runctx(command, globals, locals, filename=None, sort=-1)
+
+   Profile execution of a command with explicit namespaces.
+
+   Like :func:`run`, but executes the command with the specified *globals*
+   and *locals* mappings instead of using the ``__main__`` module's namespace::
+
+      exec(command, globals, locals)
+
+
+.. class:: Profile(timer=None, timeunit=0.0, subcalls=True, builtins=True)
+
+   A profiler object that collects execution statistics.
+
+   The optional *timer* argument specifies a custom timing function. If not
+   provided, the profiler uses a platform-appropriate default timer. When
+   supplying a custom timer, it must return a single number representing the
+   current time. If the timer returns integers, use *timeunit* to specify the
+   duration of one time unit (for example, ``0.001`` for milliseconds).
+
+   The *subcalls* argument controls whether the profiler tracks call
+   relationships between functions. The *builtins* argument controls whether
+   built-in functions are profiled.
+
+   .. versionchanged:: 3.8
+      Added context manager support.
+
+   .. method:: enable()
+
+      Start collecting profiling data.
+
+   .. method:: disable()
+
+      Stop collecting profiling data.
+
+   .. method:: create_stats()
+
+      Stop collecting data and record the results internally as the current
+      profile.
+
+   .. method:: print_stats(sort=-1)
+
+      Create a :class:`pstats.Stats` object from the current profile and print
+      the results to standard output.
+
+      The *sort* argument specifies the sorting order. It accepts a single
+      key or a tuple of keys for multi-level sorting, using the same values
+      as :meth:`pstats.Stats.sort_stats`.
+
+      .. versionadded:: 3.13
+         Support for a tuple of sort keys.
+
+   .. method:: dump_stats(filename)
+
+      Write the current profile data to *filename*. The file can be read by
+      :class:`pstats.Stats` for later analysis.
+
+   .. method:: run(cmd)
+
+      Profile the command string via :func:`exec`.
+
+   .. method:: runctx(cmd, globals, locals)
+
+      Profile the command string via :func:`exec` with the specified
+      namespaces.
+
+   .. method:: runcall(func, /, *args, **kwargs)
+
+      Profile a function call. Returns whatever *func* returns::
+
+         result = pr.runcall(my_function, arg1, arg2, keyword=value)
+
+.. note::
+
+   Profiling requires that the profiled code returns normally. If the
+   interpreter terminates (for example, via :func:`sys.exit`) during
+   profiling, no results will be available.
+
+
+Using a custom timer
+====================
+
+The :class:`Profile` class accepts a custom timing function, allowing you to
+measure different aspects of execution such as wall-clock time or CPU time.
+Pass the timing function to the constructor::
+
+   pr = profiling.tracing.Profile(my_timer_function)
+
+The timer function must return a single number representing the current time.
+If it returns integers, also specify *timeunit* to indicate the duration of
+one unit::
+
+   # Timer returns time in milliseconds
+   pr = profiling.tracing.Profile(my_ms_timer, 0.001)
+
+For best performance, the timer function should be as fast as possible. The
+profiler calls it frequently, so timer overhead directly affects profiling
+overhead.
+
+The :mod:`time` module provides several functions suitable for use as custom
+timers:
+
+- :func:`time.perf_counter` for high-resolution wall-clock time
+- :func:`time.process_time` for CPU time (excluding sleep)
+- :func:`time.monotonic` for monotonic clock time
+
+
+Limitations
+===========
+
+Deterministic profiling has inherent limitations related to timing accuracy.
+
+The underlying timer typically has a resolution of about one millisecond.
+Measurements cannot be more accurate than this resolution. With enough
+measurements, timing errors tend to average out, but individual measurements
+may be imprecise.
+
+There is also latency between when an event occurs and when the profiler
+captures the timestamp. Similarly, there is latency after reading the
+timestamp before user code resumes. Functions called frequently accumulate
+this latency, which can make them appear slower than they actually are. This
+error is typically less than one clock tick per call but can become
+significant for functions called many times.
+
+The :mod:`!profiling.tracing` module (and its ``cProfile`` alias) is
+implemented as a C extension with low overhead, so these timing issues are
+less pronounced than with the deprecated pure Python :mod:`profile` module.

+*******************************************
+:mod:`!pstats` --- Statistics for profilers
+*******************************************
+
+.. module:: pstats
+   :synopsis: Statistics object for analyzing profiler output.
+
+**Source code:** :source:`Lib/pstats.py`
+
+--------------
+
+The :mod:`!pstats` module provides tools for reading, manipulating, and
+displaying profiling statistics generated by Python's profilers. It reads
+output from both :mod:`profiling.tracing` (deterministic profiler) and
+:mod:`profiling.sampling` (statistical profiler).
+
+
+Reading and displaying profile data
+===================================
+
+The :class:`Stats` class is the primary interface for working with profile
+data. It can read statistics from files or directly from a
+:class:`~profiling.tracing.Profile` object.
+
+Load statistics from a file and print a basic report::
+
+   import pstats
+
+   p = pstats.Stats('profile_output.prof')
+   p.print_stats()
+
+The :class:`Stats` object provides methods for sorting and filtering the
+data before printing. For example, to see the ten functions with the highest
+cumulative time::
+
+   from pstats import SortKey
+
+   p = pstats.Stats('profile_output.prof')
+   p.sort_stats(SortKey.CUMULATIVE).print_stats(10)
+
+
+Working with statistics
+-----------------------
+
+The :class:`Stats` class supports method chaining, making it convenient to
+perform multiple operations::
+
+   p = pstats.Stats('restats')
+   p.strip_dirs().sort_stats(-1).print_stats()
+
+The :meth:`~Stats.strip_dirs` method removes directory paths from filenames,
+making the output more compact. The :meth:`~Stats.sort_stats` method accepts
+various keys to control the sort order.
+
+Different sort keys highlight different aspects of performance::
+
+   from pstats import SortKey
+
+   # Functions that consume the most cumulative time
+   p.sort_stats(SortKey.CUMULATIVE).print_stats(10)
+
+   # Functions that consume the most time in their own code
+   p.sort_stats(SortKey.TIME).print_stats(10)
+
+   # Functions sorted by name
+   p.sort_stats(SortKey.NAME).print_stats()
+
+
+Filtering output
+----------------
+
+The :meth:`~Stats.print_stats` method accepts restrictions that filter
+which functions are displayed. Restrictions can be integers (limiting the
+count), floats between 0 and 1 (selecting a percentage), or strings (matching
+function names via regular expression).
+
+Print only the top 10%::
+
+   p.print_stats(.1)
+
+Print only functions whose names contain "init"::
+
+   p.print_stats('init')
+
+Combine restrictions (they apply sequentially)::
+
+   # Top 10%, then only those containing "init"
+   p.print_stats(.1, 'init')
+
+   # Functions in files matching "foo:", limited to top 50%
+   p.sort_stats(SortKey.FILENAME).print_stats('foo:', .5)
+
+
+Analyzing call relationships
+----------------------------
+
+The :meth:`~Stats.print_callers` method shows which functions called each
+displayed function::
+
+   p.print_callers()
+
+The :meth:`~Stats.print_callees` method shows the opposite relationship,
+listing which functions each displayed function called::
+
+   p.print_callees()
+
+Both methods accept the same restriction arguments as :meth:`~Stats.print_stats`.
+
+
+Combining multiple profiles
+---------------------------
+
+Statistics from multiple profiling runs can be combined into a single
+:class:`Stats` object::
+
+   # Load multiple files at once
+   p = pstats.Stats('run1.prof', 'run2.prof', 'run3.prof')
+
+   # Or add files incrementally
+   p = pstats.Stats('run1.prof')
+   p.add('run2.prof')
+   p.add('run3.prof')
+
+When files are combined, statistics for identical functions (same file, line,
+and name) are accumulated, giving an aggregate view across all profiling runs.
+
+
+The :class:`!Stats` class
+=========================
+
+.. class:: Stats(*filenames_or_profile, stream=sys.stdout)
+
+   Create a statistics object from profile data.
+
+   The arguments can be filenames (strings or path-like objects) or
+   :class:`~profiling.tracing.Profile` objects. If multiple sources are
+   provided, their statistics are combined.
+
+   The *stream* argument specifies where output from :meth:`print_stats` and
+   related methods is written. It defaults to :data:`sys.stdout`.
+
+   The profile data format is specific to the Python version that created it.
+   There is no compatibility guarantee between Python versions or between
+   different profilers.
+
+   .. method:: strip_dirs()
+
+      Remove leading path information from all filenames.
+
+      This method modifies the object in place and returns it for method
+      chaining. After stripping, the statistics are considered to be in
+      random order.
+
+      If stripping causes two functions to become indistinguishable (same
+      filename, line number, and function name), their statistics are
+      combined into a single entry.
+
+   .. method:: add(*filenames)
+
+      Add profiling data from additional files.
+
+      The files must have been created by the same profiler type. Statistics
+      for identical functions are accumulated.
+
+   .. method:: dump_stats(filename)
+
+      Save the current statistics to a file.
+
+      The file is created if it does not exist and overwritten if it does.
+      The saved data can be loaded by creating a new :class:`Stats` object.
+
+   .. method:: sort_stats(*keys)
+
+      Sort the statistics according to the specified criteria.
+
+      Each key can be a string or a :class:`SortKey` enum member. When
+      multiple keys are provided, later keys break ties in earlier keys.
+
+      Using :class:`SortKey` enum members is preferred over strings as it
+      provides better error checking::
+
+         from pstats import SortKey
+         p.sort_stats(SortKey.CUMULATIVE)
+
+      Valid sort keys:
+
+      +------------------+------------------------+----------------------+
+      | String           | Enum                   | Meaning              |
+      +==================+========================+======================+
+      | ``'calls'``      | ``SortKey.CALLS``      | call count           |
+      +------------------+------------------------+----------------------+
+      | ``'cumulative'`` | ``SortKey.CUMULATIVE`` | cumulative time      |

+      +------------------+------------------------+----------------------+
+      | ``'ncalls'``     | N/A                    | call count           |
+      +------------------+------------------------+----------------------+
+      | ``'pcalls'``     | ``SortKey.PCALLS``     | primitive call count |
+      +------------------+------------------------+----------------------+
+      | ``'line'``       | ``SortKey.LINE``       | line number          |
+      +------------------+------------------------+----------------------+
+      | ``'name'``       | ``SortKey.NAME``       | function name        |
+      +------------------+------------------------+----------------------+
+      | ``'nfl'``        | ``SortKey.NFL``        | name/file/line       |
+      +------------------+------------------------+----------------------+
+      | ``'stdname'``    | ``SortKey.STDNAME``    | standard name        |
+      +------------------+------------------------+----------------------+
+      | ``'time'``       | ``SortKey.TIME``       | internal time        |
+      +------------------+------------------------+----------------------+
+      | ``'tottime'``    | N/A                    | internal time        |
+      +------------------+------------------------+----------------------+
+
+      All sorts on statistics are in descending order (most time consuming
+      first), while name, file, and line number sorts are ascending
+      (alphabetical).
+
+      The difference between ``SortKey.NFL`` and ``SortKey.STDNAME`` is that
+      NFL sorts line numbers numerically while STDNAME sorts them as strings.
+      ``sort_stats(SortKey.NFL)`` is equivalent to
+      ``sort_stats(SortKey.NAME, SortKey.FILENAME, SortKey.LINE)``.
+
+      For backward compatibility, the numeric arguments ``-1``, ``0``, ``1``,
+      and ``2`` are also accepted, meaning ``'stdname'``, ``'calls'``,
+      ``'time'``, and ``'cumulative'`` respectively.
+
+      .. versionadded:: 3.7
+         The :class:`SortKey` enum.
+
+   .. method:: reverse_order()
+
+      Reverse the current sort order.
+
+      By default, the sort direction is chosen appropriately for the sort key
+      (descending for time-based keys, ascending for name-based keys). This
+      method inverts that choice.
+
+   .. method:: print_stats(*restrictions)
+
+      Print a report of the profiling statistics.
+
+      The output includes a header line summarizing the data, followed by a
+      table of function statistics sorted according to the last
+      :meth:`sort_stats` call.
+
+      Restrictions filter the output. Each restriction is either:
+
+      - An integer: limits output to that many entries
+      - A float between 0.0 and 1.0: selects that fraction of entries
+      - A string: matches function names via regular expression
+
+      Restrictions are applied sequentially. For example::
+
+         print_stats(.1, 'foo:')
+
+      First limits to the top 10%, then filters to functions matching 'foo:'.
+
+   .. method:: print_callers(*restrictions)
+
+      Print the callers of each function in the statistics.
+
+      For each function in the filtered results, shows which functions called
+      it and how often.
+
+      With :mod:`profiling.tracing` (or ``cProfile``), each caller line
+      shows three numbers: the number of calls from that caller, and the
+      total and cumulative times for those specific calls.
+
+      Accepts the same restriction arguments as :meth:`print_stats`.
+
+   .. method:: print_callees(*restrictions)
+
+      Print the functions called by each function in the statistics.
+
+      This is the inverse of :meth:`print_callers`, showing which functions
+      each listed function called.
+
+      Accepts the same restriction arguments as :meth:`print_stats`.
+
+   .. method:: get_stats_profile()
+
+      Return a ``StatsProfile`` object containing the statistics.
+
+      The returned object provides programmatic access to the profile data,
+      with function names mapped to ``FunctionProfile`` objects
+      containing timing and call count information.
+
+      .. versionadded:: 3.9
+
+
+.. class:: SortKey
+
+   An enumeration of valid sort keys for :meth:`Stats.sort_stats`.
+

+prefixmatch() vs. match()
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Why is the :func:`~re.match` function and method discouraged in
+favor of the longer :func:`~re.prefixmatch` spelling?
+
+Many other languages have gained regex support libraries since regular
+expressions were added to Python. However in the most popular of those, they
+use the term *match* in their APIs to mean the unanchored behavior provided in
+Python by :func:`~re.search`. Thus use of the plain term *match* can be
+unclear to those used to other languages when reading or writing code and
+not familiar with the Python API's divergence from what otherwise become the
+industry norm.
+
+Quoting from the Zen Of Python (``python3 -m this``): *"Explicit is better than
+implicit"*. Anyone reading the name :func:`!prefixmatch` is likely to
+understand the intended semantics. When reading :func:`!match` there remains
+a seed of doubt about the intended behavior to anyone not already familiar with
+this old Python gotcha.
+
+We **do not** plan to remove the older :func:`!match` name,
+as it has been used in code for over 30 years.
+It has been :term:`soft deprecated`:
+code supporting older versions of Python should continue to use :func:`!match`,
+while new code should prefer :func:`!prefixmatch`.

+Startup entry points (:file:`.start` files)

+
+.. versionadded:: 3.15
+
+A startup entry point file is a file whose name has the form
+:file:`{name}.start` and exists in one of the site-packages directories
+described above.  Each file specifies entry points to be called during
+interpreter startup, using the ``pkg.mod:callable`` syntax understood by
+:func:`pkgutil.resolve_name`.
+
+Each non-blank line that does not begin with ``#`` must contain an entry
+point reference in the form ``pkg.mod:callable``.  The colon and callable
+portion are mandatory.  Each callable is invoked with no arguments, and
+any return value is discarded.
+
+:file:`.start` files are processed after all :file:`.pth` path extensions
+have been applied to :data:`sys.path`, ensuring that paths are available
+before any startup code runs.
+
+Unlike :data:`sys.path` extensions from :file:`.pth` files, duplicate entry
+points are **not** de-duplicated --- if an entry point appears more than once,
+it will be called more than once.
+
+If an exception occurs during resolution or invocation of an entry point,
+a traceback is printed to :data:`sys.stderr` and processing continues with
+the remaining entry points.
+
+:file:`.start` files must be encoded in UTF-8.
+
+:pep:`829` defined the original specification for these features.
+
+.. note::
+
+   If a :file:`{name}.start` file exists alongside a :file:`{name}.pth` file
+   with the same base name, any ``import`` lines in the :file:`.pth` file are
+   ignored in favor of the entry points in the :file:`.start` file.
+
+.. note::
+
+   Executable lines (``import`` lines in :file:`{name}.pth` files and
+   :file:`{name}.start` file entry points) are always run at Python startup
+   (unless :option:`-S` is given to disable the ``site.py`` module entirely),

-   buffer sizes for ancillary data can be calculated using
-   :func:`CMSG_SPACE` or :func:`CMSG_LEN`, and items which do not fit
-   into the buffer might be truncated or discarded.  The *flags*
-   argument defaults to 0 and has the same meaning as for
-   :meth:`recv`.
-
-   The return value is a 4-tuple: ``(data, ancdata, msg_flags,
-   address)``.  The *data* item is a :class:`bytes` object holding the
-   non-ancillary data received.  The *ancdata* item is a list of zero
-   or more tuples ``(cmsg_level, cmsg_type, cmsg_data)`` representing
-   the ancillary data (control messages) received: *cmsg_level* and
-   *cmsg_type* are integers specifying the protocol level and
-   protocol-specific type respectively, and *cmsg_data* is a
-   :class:`bytes` object holding the associated data.  The *msg_flags*
-   item is the bitwise OR of various flags indicating conditions on
-   the received message; see your system documentation for details.
-   If the receiving socket is unconnected, *address* is the address of
-   the sending socket, if available; otherwise, its value is
-   unspecified.
-
-   On some systems, :meth:`sendmsg` and :meth:`recvmsg` can be used to
-   pass file descriptors between processes over an :const:`AF_UNIX`
-   socket.  When this facility is used (it is often restricted to
-   :const:`SOCK_STREAM` sockets), :meth:`recvmsg` will return, in its
-   ancillary data, items of the form ``(socket.SOL_SOCKET,
-   socket.SCM_RIGHTS, fds)``, where *fds* is a :class:`bytes` object
-   representing the new file descriptors as a binary array of the
-   native C :c:expr:`int` type.  If :meth:`recvmsg` raises an
-   exception after the system call returns, it will first attempt to
-   close any file descriptors received via this mechanism.
-
-   Some systems do not indicate the truncated length of ancillary data
-   items which have been only partially received.  If an item appears
-   to extend beyond the end of the buffer, :meth:`recvmsg` will issue
-   a :exc:`RuntimeWarning`, and will return the part of it which is
-   inside the buffer provided it has not been truncated before the
-   start of its associated data.
-
-   On systems which support the :const:`SCM_RIGHTS` mechanism, the
-   following function will receive up to *maxfds* file descriptors,
-   returning the message data and a list containing the descriptors
-   (while ignoring unexpected conditions such as unrelated control
-   messages being received).  See also :meth:`sendmsg`. ::

+   .. method:: recvmsg(bufsize[, ancbufsize[, flags]])
+
+      Receive normal data (up to *bufsize* bytes) and ancillary data from
+      the socket.  The *ancbufsize* argument sets the size in bytes of
+      the internal buffer used to receive the ancillary data; it defaults
+      to 0, meaning that no ancillary data will be received.  Appropriate
+      buffer sizes for ancillary data can be calculated using
+      :func:`CMSG_SPACE` or :func:`CMSG_LEN`, and items which do not fit
+      into the buffer might be truncated or discarded.  The *flags*
+      argument defaults to 0 and has the same meaning as for
+      :meth:`recv`.
+
+      The return value is a 4-tuple: ``(data, ancdata, msg_flags,
+      address)``.  The *data* item is a :class:`bytes` object holding the
+      non-ancillary data received.  The *ancdata* item is a list of zero
+      or more tuples ``(cmsg_level, cmsg_type, cmsg_data)`` representing
+      the ancillary data (control messages) received: *cmsg_level* and
+      *cmsg_type* are integers specifying the protocol level and
+      protocol-specific type respectively, and *cmsg_data* is a
+      :class:`bytes` object holding the associated data.  The *msg_flags*
+      item is the bitwise OR of various flags indicating conditions on
+      the received message; see your system documentation for details.
+      If the receiving socket is unconnected, *address* is the address of
+      the sending socket, if available; otherwise, its value is
+      unspecified.
+
+      On some systems, :meth:`sendmsg` and :meth:`recvmsg` can be used to
+      pass file descriptors between processes over an :const:`AF_UNIX`
+      socket.  When this facility is used (it is often restricted to
+      :const:`SOCK_STREAM` sockets), :meth:`recvmsg` will return, in its
+      ancillary data, items of the form ``(socket.SOL_SOCKET,
+      socket.SCM_RIGHTS, fds)``, where *fds* is a :class:`bytes` object
+      representing the new file descriptors as a binary array of the
+      native C :c:expr:`int` type.  If :meth:`recvmsg` raises an
+      exception after the system call returns, it will first attempt to
+      close any file descriptors received via this mechanism.
+
+      Some systems do not indicate the truncated length of ancillary data
+      items which have been only partially received.  If an item appears
+      to extend beyond the end of the buffer, :meth:`recvmsg` will issue
+      a :exc:`RuntimeWarning`, and will return the part of it which is
+      inside the buffer provided it has not been truncated before the
+      start of its associated data.
+
+      On systems which support the :const:`!SCM_RIGHTS` mechanism, the
+      following function will receive up to *maxfds* file descriptors,
+      returning the message data and a list containing the descriptors
+      (while ignoring unexpected conditions such as unrelated control
+      messages being received).  See also :meth:`sendmsg`. ::
+
+         import socket, array
+
+         def recv_fds(sock, msglen, maxfds):
+             fds = array.array("i")   # Array of ints
+             msg, ancdata, flags, addr = sock.recvmsg(msglen, socket.CMSG_LEN(maxfds * fds.itemsize))
+             for cmsg_level, cmsg_type, cmsg_data in ancdata:
+                 if cmsg_level == socket.SOL_SOCKET and cmsg_type == socket.SCM_RIGHTS:
+                     # Append data, ignoring any truncated integers at the end.
+                     fds.frombytes(cmsg_data[:len(cmsg_data) - (len(cmsg_data) % fds.itemsize)])

    Many restrictions on expressions within f-strings have been removed.
    Notably, nested strings, comments, and backslashes are now permitted.
 
 An :dfn:`f-string` (formally a :dfn:`formatted string literal`) is
 a string literal that is prefixed with ``f`` or ``F``.
-This type of string literal allows embedding arbitrary Python expressions
-within *replacement fields*, which are delimited by curly brackets (``{}``).
-These expressions are evaluated at runtime, similarly to :meth:`str.format`,
-and are converted into regular :class:`str` objects.
-For example:
+This type of string literal allows embedding the results of arbitrary Python
+expressions within *replacement fields*, which are delimited by curly
+brackets (``{}``).
+Each replacement field must contain an expression, optionally followed by:
 
-.. doctest::
+* a *debug specifier* -- an equal sign (``=``);
+* a *conversion specifier* -- ``!s``, ``!r`` or ``!a``; and/or
+* a *format specifier* prefixed with a colon (``:``).
 
-   >>> who = 'nobody'
-   >>> nationality = 'Spanish'
-   >>> f'{who.title()} expects the {nationality} Inquisition!'
-   'Nobody expects the Spanish Inquisition!'
+See the :ref:`Lexical Analysis section on f-strings <f-strings>` for details
+on the syntax of these fields.
 
-It is also possible to use a multi line f-string:
+Debug specifier
+^^^^^^^^^^^^^^^
 
-.. doctest::
-
-   >>> f'''This is a string
-   ... on two lines'''
-   'This is a string\non two lines'
-
-A single opening curly bracket, ``'{'``, marks a *replacement field* that
-can contain any Python expression:
-
-.. doctest::
-
-   >>> nationality = 'Spanish'
-   >>> f'The {nationality} Inquisition!'
-   'The Spanish Inquisition!'
+.. versionadded:: 3.8
 
-To include a literal ``{`` or ``}``, use a double bracket:
-
-.. doctest::
+If a debug specifier -- an equal sign (``=``) -- appears after the replacement
+field expression, the resulting f-string will contain the expression's source,
+the equal sign, and the value of the expression.
+This is often useful for debugging::
 
-   >>> x = 42
-   >>> f'{{x}} is {x}'
-   '{x} is 42'
+   >>> number = 14.3
+   >>> f'{number=}'
+   'number=14.3'
 
-Functions can also be used, and :ref:`format specifiers <formatstrings>`:
+Whitespace before, inside and after the expression, as well as whitespace
+after the equal sign, is significant --- it is retained in the result::
 
-.. doctest::
+   >>> f'{ number  -  4  = }'
+   ' number  -  4  = 10.3'
 
-   >>> from math import sqrt
-   >>> f'√2 \N{ALMOST EQUAL TO} {sqrt(2):.5f}'
-   '√2 ≈ 1.41421'
 
-Any non-string expression is converted using :func:`str`, by default:
+Conversion specifier
+^^^^^^^^^^^^^^^^^^^^
 
-.. doctest::
+By default, the value of a replacement field expression is converted to
+a string using :func:`str`::
 
    >>> from fractions import Fraction
-   >>> f'{Fraction(1, 3)}'
+   >>> one_third = Fraction(1, 3)
+   >>> f'{one_third}'
    '1/3'
 
-To use an explicit conversion, use the ``!`` (exclamation mark) operator,
-followed by any of the valid formats, which are:
+When a debug specifier but no format specifier is used, the default conversion
+instead uses :func:`repr`::
 
-========== ==============
-Conversion  Meaning
-========== ==============
-``!a``      :func:`ascii`
-``!r``      :func:`repr`
-``!s``      :func:`str`
-========== ==============
+   >>> f'{one_third = }'
+   'one_third = Fraction(1, 3)'
 
-For example:
+The conversion can be specified explicitly using one of these specifiers:
 
-.. doctest::
+* ``!s`` for :func:`str`
+* ``!r`` for :func:`repr`
+* ``!a`` for :func:`ascii`
 
-   >>> from fractions import Fraction
-   >>> f'{Fraction(1, 3)!s}'
+For example::
+
+   >>> str(one_third)
    '1/3'
-   >>> f'{Fraction(1, 3)!r}'
+   >>> repr(one_third)
    'Fraction(1, 3)'
-   >>> question = '¿Dónde está el Presidente?'
-   >>> print(f'{question!a}')
-   '\xbfD\xf3nde est\xe1 el Presidente?'
-
-While debugging it may be helpful to see both the expression and its value,
-by using the equals sign (``=``) after the expression.
-This preserves spaces within the brackets, and can be used with a converter.
-By default, the debugging operator uses the :func:`repr` (``!r``) conversion.
-For example:
 
-.. doctest::
+   >>> f'{one_third!s} is {one_third!r}'
+   '1/3 is Fraction(1, 3)'
 
-   >>> from fractions import Fraction
-   >>> calculation = Fraction(1, 3)
-   >>> f'{calculation=}'
-   'calculation=Fraction(1, 3)'
-   >>> f'{calculation = }'
-   'calculation = Fraction(1, 3)'
-   >>> f'{calculation = !s}'
-   'calculation = 1/3'
-
-Once the output has been evaluated, it can be formatted using a
-:ref:`format specifier <formatstrings>` following a colon (``':'``).
-After the expression has been evaluated, and possibly converted to a string,
-the :meth:`!__format__` method of the result is called with the format specifier,
-or the empty string if no format specifier is given.
-The formatted result is then used as the final value for the replacement field.
-For example:
+   >>> string = "¡kočka 😸!"
+   >>> ascii(string)
+   "'\\xa1ko\\u010dka \\U0001f638!'"
+
+   >>> f'{string = !a}'
+   "string = '\\xa1ko\\u010dka \\U0001f638!'"
 
-.. doctest::
+
+Format specifier
+^^^^^^^^^^^^^^^^
+
+After the expression has been evaluated, and possibly converted using an
+explicit conversion specifier, it is formatted using the :func:`format` function.
+If the replacement field includes a *format specifier* introduced by a colon
+(``:``), the specifier is passed to :func:`!format` as the second argument.
+The result of :func:`!format` is then used as the final value for the
+replacement field. For example::
 
    >>> from fractions import Fraction
-   >>> f'{Fraction(1, 7):.6f}'
-   '0.142857'
-   >>> f'{Fraction(1, 7):_^+10}'
-   '___+1/7___'
+   >>> one_third = Fraction(1, 3)
+   >>> f'{one_third:.6f}'
+   '0.333333'
+   >>> f'{one_third:_^+10}'
+   '___+1/3___'
+   >>> >>> f'{one_third!r:_^20}'
+   '___Fraction(1, 3)___'
+   >>> f'{one_third = :~>10}~'

+Template String Literals (t-strings)
+------------------------------------
+
+An :dfn:`t-string` (formally a :dfn:`template string literal`) is
+a string literal that is prefixed with ``t`` or ``T``.
+
+These strings follow the same syntax and evaluation rules as
+:ref:`formatted string literals <stdtypes-fstrings>`,
+with for the following differences:
+
+* Rather than evaluating to a ``str`` object, template string literals evaluate
+  to a :class:`string.templatelib.Template` object.
+
+* The :func:`format` protocol is not used.
+  Instead, the format specifier and conversions (if any) are passed to
+  a new :class:`~string.templatelib.Interpolation` object that is created
+  for each evaluated expression.
+  It is up to code that processes the resulting :class:`~string.templatelib.Template`
+  object to decide how to handle format specifiers and conversions.
+
+* Format specifiers containing nested replacement fields are evaluated eagerly,
+  prior to being passed to the :class:`~string.templatelib.Interpolation` object.
+  For instance, an interpolation of the form ``{amount:.{precision}f}`` will
+  evaluate the inner expression ``{precision}`` to determine the value of the
+  ``format_spec`` attribute.
+  If ``precision`` were to be ``2``, the resulting format specifier
+  would be ``'.2f'``.
+
+* When the equals sign ``'='`` is provided in an interpolation expression,
+  the text of the expression is appended to the literal string that precedes
+  the relevant interpolation.
+  This includes the equals sign and any surrounding whitespace.
+  The :class:`!Interpolation` instance for the expression will be created as
+  normal, except that :attr:`~string.templatelib.Interpolation.conversion` will
+  be set to '``r``' (:func:`repr`) by default.
+  If an explicit conversion or format specifier are provided,
+  this will override the default behaviour.

+Iterator synchronization
+------------------------
+
+By default, Python iterators do not support concurrent access. Most iterators make
+no guarantees when accessed simultaneously from multiple threads. Generator
+iterators, for example, raise :exc:`ValueError` if one of their iterator methods
+is called while the generator is already executing. The tools in this section
+allow reliable concurrency support to be added to ordinary iterators and
+iterator-producing callables.
+
+The :class:`serialize_iterator` wrapper lets multiple threads share a single iterator and
+take turns consuming from it. While one thread is running ``__next__()``, the
+others block until the iterator becomes available. Each value produced by the
+underlying iterator is delivered to exactly one caller.
+
+The :func:`concurrent_tee` function lets multiple threads each receive the full
+stream of values from one underlying iterator. It creates independent iterators
+that all draw from the same source. Values are buffered until consumed by all
+of the derived iterators.
+
+.. class:: serialize_iterator(iterable)
+
+   Return an iterator wrapper that serializes concurrent calls to
+   :meth:`~iterator.__next__` using a lock.
+
+   If the wrapped iterator also defines :meth:`~generator.send`,
+   :meth:`~generator.throw`, or :meth:`~generator.close`, those calls
+   are serialized as well.
+
+   This makes it possible to share a single iterator, including a generator
+   iterator, between multiple threads. A lock ensures that calls are handled
+   one at a time. No values are duplicated or skipped by the wrapper itself.
+   Each item from the underlying iterator is given to exactly one caller.
+
+   This wrapper does not copy or buffer values. Threads that call
+   :func:`next` while another thread is already advancing the iterator will
+   block until the active call completes.
+
+   Example:
+
+   .. code-block:: python
+
+      import threading
+
+      def squares(n):
+          for x in range(n):
+              yield x * x
+
+      def consume(name, iterable):
+          for item in iterable:
+              print(name, item)
+
+      source = threading.serialize_iterator(squares(5))
+
+      t1 = threading.Thread(target=consume, args=("left", source))
+      t2 = threading.Thread(target=consume, args=("right", source))
+      t1.start()
+      t2.start()
+      t1.join()
+      t2.join()
+
+   In this example, each number is printed exactly once, but the work is shared
+   between the two threads.
+
+   .. versionadded:: 3.15
+
+
+.. function:: synchronized_iterator(func)
+
+   Wrap an iterator-producing callable so that each iterator it returns is
+   automatically passed through :class:`serialize_iterator`.
+
+   This is especially useful as a :term:`decorator` for generator functions,
+   allowing their generator-iterators to be consumed from multiple threads.
+
+   Example:
+
+   .. code-block:: python
+
+      import threading
+
+      @threading.synchronized_iterator
+      def squares(n):
+          for x in range(n):
+              yield x * x
+
+      def consume(name, iterable):
+          for item in iterable:
+              print(name, item)
+
+      source = squares(5)
+
+      t1 = threading.Thread(target=consume, args=("left", source))
+      t2 = threading.Thread(target=consume, args=("right", source))
+      t1.start()
+      t2.start()
+      t1.join()
+      t2.join()
+
+   The returned wrapper preserves the metadata of *func*, such as its name and
+   wrapped function reference.
+
+   .. versionadded:: 3.15
+
+
+.. function:: concurrent_tee(iterable, n=2)
+
+   Return *n* independent iterators from a single input *iterable*, with
+   guaranteed behavior when the derived iterators are consumed concurrently.
+
+   This function is similar to :func:`itertools.tee`, but is intended for cases
+   where the source iterator may feed consumers running in different threads.
+   Each returned iterator yields every value from the underlying iterable, in
+   the same order.
+
+   Internally, values are buffered until every derived iterator has consumed
+   them.
+
+   The returned iterators share the same underlying synchronization lock. Each
+   individual derived iterator is intended to be consumed by one thread at a
+   time. If a single derived iterator must itself be shared by multiple
+   threads, wrap it with :class:`serialize_iterator`.
+
+   If *n* is ``0``, return an empty tuple. If *n* is negative, raise
+   :exc:`ValueError`.
+
+   Example:
+
+   .. code-block:: python
+
+      import threading
+
+      def squares(n):
+          for x in range(n):
+              yield x * x
+
+      def consume(name, iterable):
+          for item in iterable:
+              print(name, item)
+
+      source = squares(5)
+      left, right = threading.concurrent_tee(source)
+
+      t1 = threading.Thread(target=consume, args=("left", left))
+      t2 = threading.Thread(target=consume, args=("right", right))
+      t1.start()
+      t2.start()
+      t1.join()
+      t2.join()
+
+   In this example, both consumer threads see the full sequence of squares
+   from a single generator expression.

+
+************************
+Thread Safety Guarantees
+************************
+
+This page documents thread-safety guarantees for built-in types in Python's
+free-threaded build. The guarantees described here apply when using Python with
+the :term:`GIL` disabled (free-threaded mode). When the GIL is enabled, most
+operations are implicitly serialized.
+
+For general guidance on writing thread-safe code in free-threaded Python, see
+:ref:`freethreading-python-howto`.
+
+
+.. _threadsafety-levels:
+
+Thread safety levels
+====================
+
+The C API documentation uses the following levels to describe the thread
+safety guarantees of each function. The levels are listed from least to
+most safe.
+
+.. _threadsafety-level-incompatible:
+
+Incompatible
+------------
+
+A function or operation that cannot be made safe for concurrent use even
+with external synchronization. Incompatible code typically accesses
+global state in an unsynchronized way and must only be called from a single
+thread throughout the program's lifetime.
+
+Example: a function that modifies process-wide state such as signal handlers
+or environment variables, where concurrent calls from any threads, even with
+external locking, can conflict with the runtime or other libraries.
+
+.. _threadsafety-level-compatible:
+
+Compatible
+----------
+
+A function or operation that is safe to call from multiple threads
+*provided* the caller supplies appropriate external synchronization, for
+example by holding a :term:`lock` for the duration of each call. Without
+such synchronization, concurrent calls may produce :term:`race conditions
+<race condition>` or :term:`data races <data race>`.
+
+Example: a function that reads from or writes to an object whose internal
+state is not protected by a lock. Callers must ensure that no two threads
+access the same object at the same time.
+
+.. _threadsafety-level-distinct:
+
+Safe on distinct objects
+------------------------
+
+A function or operation that is safe to call from multiple threads without
+external synchronization, as long as each thread operates on a **different**
+object. Two threads may call the function at the same time, but they must
+not pass the same object (or objects that share underlying state) as
+arguments.
+
+Example: a function that modifies fields of a struct using non-atomic
+writes. Two threads can each call the function on their own struct
+instance safely, but concurrent calls on the *same* instance require
+external synchronization.
+
+.. _threadsafety-level-shared:
+
+Safe on shared objects
+----------------------
+
+A function or operation that is safe for concurrent use on the **same**
+object. The implementation uses internal synchronization (such as
+:term:`per-object locks <per-object lock>` or
+:ref:`critical sections <python-critical-section-api>`) to protect shared
+mutable state, so callers do not need to supply their own locking.
+
+Example: :c:func:`PyList_GetItemRef` can be called from multiple threads on the
+same :c:type:`PyListObject` - it uses internal synchronization to serialize
+access.
+
+.. _threadsafety-level-atomic:
+
+Atomic
+------
+
+A function or operation that appears :term:`atomic <atomic operation>` with
+respect to other threads - it executes instantaneously from the perspective
+of other threads. This is the strongest form of thread safety.
+
+Example: :c:func:`PyMutex_IsLocked` performs an atomic read of the mutex
+state and can be called from any thread at any time.
+
+
+.. _thread-safety-list:
+
+Thread safety for list objects
+==============================
+
+Reading a single element from a :class:`list` is
+:term:`atomic <atomic operation>`:
+
+.. code-block::
+   :class: good
+
+   lst[i]   # list.__getitem__
+
+The following methods traverse the list and use :term:`atomic <atomic operation>`
+reads of each item to perform their function. That means that they may
+return results affected by concurrent modifications:
+
+.. code-block::
+   :class: maybe
+
+   item in lst
+   lst.index(item)
+   lst.count(item)
+
+All of the above operations avoid acquiring :term:`per-object locks
+<per-object lock>`. They do not block concurrent modifications. Other
+operations that hold a lock will not block these from observing intermediate
+states.
+
+All other operations from here on block using the :term:`per-object lock`.
+
+Writing a single item via ``lst[i] = x`` is safe to call from multiple
+threads and will not corrupt the list.
+
+The following operations return new objects and appear
+:term:`atomic <atomic operation>` to other threads:
+
+.. code-block::
+   :class: good
+
+   lst1 + lst2    # concatenates two lists into a new list
+   x * lst        # repeats lst x times into a new list
+   lst.copy()     # returns a shallow copy of the list
+
+The following methods that only operate on a single element with no shifting
+required are :term:`atomic <atomic operation>`:
+
+.. code-block::
+   :class: good
+
+   lst.append(x)  # append to the end of the list, no shifting required
+   lst.pop()      # pop element from the end of the list, no shifting required
+
+The :meth:`~list.clear` method is also :term:`atomic <atomic operation>`.
+Other threads cannot observe elements being removed.
+
+The :meth:`~list.sort` method is not :term:`atomic <atomic operation>`.
+Other threads cannot observe intermediate states during sorting, but the
+list appears empty for the duration of the sort.
+
+The following operations may allow :term:`lock-free` operations to observe
+intermediate states since they modify multiple elements in place:
+
+.. code-block::
+   :class: maybe
+
+   lst.insert(idx, item)  # shifts elements
+   lst.pop(idx)           # idx not at the end of the list, shifts elements
+   lst *= x               # copies elements in place
+
+The :meth:`~list.remove` method may allow concurrent modifications since
+element comparison may execute arbitrary Python code (via
+:meth:`~object.__eq__`).
+
+:meth:`~list.extend` is safe to call from multiple threads.  However, its
+guarantees depend on the iterable passed to it. If it is a :class:`list`, a
+:class:`tuple`, a :class:`set`, a :class:`frozenset`, a :class:`dict` or a
+:ref:`dictionary view object <dict-views>` (but not their subclasses), the
+``extend`` operation is safe from concurrent modifications to the iterable.
+Otherwise, an iterator is created which can be concurrently modified by
+another thread.  The same applies to inplace concatenation of a list with
+other iterables when using ``lst += iterable``.
+
+Similarly, assigning to a list slice with ``lst[i:j] = iterable`` is safe
+to call from multiple threads, but ``iterable`` is only locked when it is
+also a :class:`list` (but not its subclasses).
+
+Operations that involve multiple accesses, as well as iteration, are never
+atomic. For example:
+
+.. code-block::
+   :class: bad
+
+   # NOT atomic: read-modify-write
+   lst[i] = lst[i] + 1
+
+   # NOT atomic: check-then-act
+   if lst:
+       item = lst.pop()
+
+   # NOT thread-safe: iteration while modifying
+   for item in lst:
+       process(item)  # another thread may modify lst
+
+Consider external synchronization when sharing :class:`list` instances
+across threads.
+
+
+.. _thread-safety-dict:
+
+Thread safety for dict objects
+==============================
+
+Creating a dictionary with the :class:`dict` constructor is atomic when the
+argument to it is a :class:`dict` or a :class:`tuple`. When using the
+:meth:`dict.fromkeys` method, dictionary creation is atomic when the
+argument is a :class:`dict`, :class:`tuple`, :class:`set` or
+:class:`frozenset`.
+
+The following operations and functions are :term:`lock-free` and
+:term:`atomic <atomic operation>`.
+
+.. code-block::
+   :class: good
+
+   d[key]       # dict.__getitem__
+   d.get(key)   # dict.get
+   key in d     # dict.__contains__
+   len(d)       # dict.__len__
+
+All other operations from here on hold the :term:`per-object lock`.
+
+Writing or removing a single item is safe to call from multiple threads
+and will not corrupt the dictionary:
+
+.. code-block::
+   :class: good
+
+   d[key] = value        # write
+   del d[key]            # delete
+   d.pop(key)            # remove and return
+   d.popitem()           # remove and return last item
+   d.setdefault(key, v)  # insert if missing
+
+These operations may compare keys using :meth:`~object.__eq__`, which can
+execute arbitrary Python code. During such comparisons, the dictionary may
+be modified by another thread. For built-in types like :class:`str`,
+:class:`int`, and :class:`float`, that implement :meth:`~object.__eq__` in C,
+the underlying lock is not released during comparisons and this is not a
+concern.
+
+The following operations return new objects and hold the :term:`per-object lock`
+for the duration of the operation:
+
+.. code-block::
+   :class: good
+
+   d.copy()      # returns a shallow copy of the dictionary
+   d | other     # merges two dicts into a new dict
+   d.keys()      # returns a new dict_keys view object
+   d.values()    # returns a new dict_values view object
+   d.items()     # returns a new dict_items view object
+
+The :meth:`~dict.clear` method holds the lock for its duration. Other
+threads cannot observe elements being removed.
+
+The following operations lock both dictionaries. For :meth:`~dict.update`
+and ``|=``, this applies only when the other operand is a :class:`dict`
+that uses the standard dict iterator (but not subclasses that override
+iteration). For equality comparison, this applies to :class:`dict` and
+its subclasses:
+
+.. code-block::
+   :class: good
+
+   d.update(other_dict)  # both locked when other_dict is a dict
+   d |= other_dict       # both locked when other_dict is a dict
+   d == other_dict       # both locked for dict and subclasses
+
+All comparison operations also compare values using :meth:`~object.__eq__`,
+so for non-built-in types the lock may be released during comparison.
+
+:meth:`~dict.fromkeys` locks both the new dictionary and the iterable
+when the iterable is exactly a :class:`dict`, :class:`set`, or
+:class:`frozenset` (not subclasses):
+
+.. code-block::
+   :class: good
+
+   dict.fromkeys(a_dict)      # locks both
+   dict.fromkeys(a_set)       # locks both
+   dict.fromkeys(a_frozenset) # locks both
+
+When updating from a non-dict iterable, only the target dictionary is
+locked. The iterable may be concurrently modified by another thread:
+
+.. code-block::
+   :class: maybe
+
+   d.update(iterable)        # iterable is not a dict: only d locked
+   d |= iterable             # iterable is not a dict: only d locked
+   dict.fromkeys(iterable)   # iterable is not a dict/set/frozenset: only result locked
+
+Operations that involve multiple accesses, as well as iteration, are never
+atomic:
+
+.. code-block::
+   :class: bad
+
+   # NOT atomic: read-modify-write
+   d[key] = d[key] + 1
+
+   # NOT atomic: check-then-act (TOCTOU)
+   if key in d:
+       del d[key]
+
+   # NOT thread-safe: iteration while modifying
+   for key, value in d.items():
+       process(key)  # another thread may modify d
+
+To avoid time-of-check to time-of-use (TOCTOU) issues, use atomic
+operations or handle exceptions:
+
+.. code-block::
+   :class: good
+
+   # Use pop() with default instead of check-then-delete
+   d.pop(key, None)
+
+   # Or handle the exception
+   try:
+       del d[key]
+   except KeyError:
+       pass
+
+To safely iterate over a dictionary that may be modified by another
+thread, iterate over a copy:
+
+.. code-block::
+   :class: good
+
+   # Make a copy to iterate safely
+   for key, value in d.copy().items():
+       process(key)
+
+Consider external synchronization when sharing :class:`dict` instances
+across threads.
+
+
+.. _thread-safety-set:
+
+Thread safety for set objects
+==============================
+
+The :func:`len` function is lock-free and :term:`atomic <atomic operation>`.
+
+The following read operation is lock-free. It does not block concurrent
+modifications and may observe intermediate states from operations that
+hold the per-object lock:
+
+.. code-block::
+   :class: good
+
+   elem in s    # set.__contains__
+
+This operation may compare elements using :meth:`~object.__eq__`, which can
+execute arbitrary Python code. During such comparisons, the set may be
+modified by another thread. For built-in types like :class:`str`,
+:class:`int`, and :class:`float`, :meth:`!__eq__` does not release the
+underlying lock during comparisons and this is not a concern.
+
+All other operations from here on hold the per-object lock.
+
+Adding or removing a single element is safe to call from multiple threads
+and will not corrupt the set:
+
+.. code-block::
+   :class: good
+
+   s.add(elem)      # add element
+   s.remove(elem)   # remove element, raise if missing
+   s.discard(elem)  # remove element if present
+   s.pop()          # remove and return arbitrary element
+
+These operations also compare elements, so the same :meth:`~object.__eq__`
+considerations as above apply.
+
+The :meth:`~set.copy` method returns a new object and holds the per-object lock
+for the duration so that it is always atomic.
+
+The :meth:`~set.clear` method holds the lock for its duration. Other
+threads cannot observe elements being removed.
+
+The following operations only accept :class:`set` or :class:`frozenset`
+as operands and always lock both objects:
+
+.. code-block::
+   :class: good
+
+   s |= other                   # other must be set/frozenset
+   s &= other                   # other must be set/frozenset
+   s -= other                   # other must be set/frozenset
+   s ^= other                   # other must be set/frozenset
+   s & other                    # other must be set/frozenset
+   s | other                    # other must be set/frozenset
+   s - other                    # other must be set/frozenset
+   s ^ other                    # other must be set/frozenset
+
+:meth:`set.update`, :meth:`set.union`, :meth:`set.intersection` and
+:meth:`set.difference` can take multiple iterables as arguments. They all
+iterate through all the passed iterables and do the following:
+
+   * :meth:`set.update` and :meth:`set.union` lock both objects only when
+      the other operand is a :class:`set`, :class:`frozenset`, or :class:`dict`.
+   * :meth:`set.intersection` and :meth:`set.difference` always try to lock
+      all objects.
+
+:meth:`set.symmetric_difference` tries to lock both objects.
+
+The update variants of the above methods also have some differences between
+them:
+
+   * :meth:`set.difference_update` and :meth:`set.intersection_update` try
+      to lock all objects one-by-one.
+   * :meth:`set.symmetric_difference_update` only locks the arguments if it is
+      of type :class:`set`, :class:`frozenset`, or :class:`dict`.
+
+The following methods always try to lock both objects:
+
+.. code-block::
+   :class: good
+
+   s.isdisjoint(other)          # both locked
+   s.issubset(other)            # both locked
+   s.issuperset(other)          # both locked
+
+Operations that involve multiple accesses, as well as iteration, are never
+atomic:
+
+.. code-block::
+   :class: bad
+
+   # NOT atomic: check-then-act
+   if elem in s:
+         s.remove(elem)
+
+   # NOT thread-safe: iteration while modifying
+   for elem in s:
+         process(elem)  # another thread may modify s
+
+Consider external synchronization when sharing :class:`set` instances
+across threads.  See :ref:`freethreading-python-howto` for more information.
+
+
+.. _thread-safety-bytearray:
+
+Thread safety for bytearray objects
+===================================
+
+   The :func:`len` function is lock-free and :term:`atomic <atomic operation>`.
+
+   Concatenation and comparisons use the buffer protocol, which prevents
+   resizing but does not hold the per-object lock. These operations may
+   observe intermediate states from concurrent modifications:
+
+   .. code-block::
+      :class: maybe
+
+      ba + other    # may observe concurrent writes
+      ba == other   # may observe concurrent writes
+      ba < other    # may observe concurrent writes
+
+   All other operations from here on hold the per-object lock.
+
+   Reading a single element or slice is safe to call from multiple threads:
+
+   .. code-block::
+      :class: good
+
+      ba[i]        # bytearray.__getitem__
+      ba[i:j]      # slice
+
+   The following operations are safe to call from multiple threads and will
+   not corrupt the bytearray:
+
+   .. code-block::
+      :class: good
+
+      ba[i] = x         # write single byte
+      ba[i:j] = values  # write slice
+      ba.append(x)      # append single byte
+      ba.extend(other)  # extend with iterable
+      ba.insert(i, x)   # insert single byte
+      ba.pop()          # remove and return last byte
+      ba.pop(i)         # remove and return byte at index
+      ba.remove(x)      # remove first occurrence
+      ba.reverse()      # reverse in place
+      ba.clear()        # remove all bytes
+
+   Slice assignment locks both objects when *values* is a :class:`bytearray`:
+
+   .. code-block::
+      :class: good
+
+      ba[i:j] = other_bytearray  # both locked
+
+   The following operations return new objects and hold the per-object lock
+   for the duration:
+
+   .. code-block::
+      :class: good
+
+      ba.copy()     # returns a shallow copy
+      ba * n        # repeat into new bytearray
+
+   The membership test holds the lock for its duration:
+
+   .. code-block::
+      :class: good
+
+      x in ba       # bytearray.__contains__
+
+   All other bytearray methods (such as :meth:`~bytearray.find`,
+   :meth:`~bytearray.replace`, :meth:`~bytearray.split`,
+   :meth:`~bytearray.decode`, etc.) hold the per-object lock for their
+   duration.
+
+   Operations that involve multiple accesses, as well as iteration, are never
+   atomic:
+
+   .. code-block::
+      :class: bad
+
+      # NOT atomic: check-then-act
+      if x in ba:
+          ba.remove(x)
+
+      # NOT thread-safe: iteration while modifying
+      for byte in ba:
+          process(byte)  # another thread may modify ba
+
+   To safely iterate over a bytearray that may be modified by another
+   thread, iterate over a copy:
+
+   .. code-block::
+      :class: good
+
+      # Make a copy to iterate safely
+      for byte in ba.copy():
+          process(byte)
+
+   Consider external synchronization when sharing :class:`bytearray` instances
+   across threads.  See :ref:`freethreading-python-howto` for more information.
+
+
+.. _thread-safety-memoryview:
+
+Thread safety for memoryview objects
+====================================
+
+:class:`memoryview` objects provide access to the internal data of an
+underlying object without copying. Thread safety depends on both the
+memoryview itself and the underlying buffer exporter.
+
+The memoryview implementation uses atomic operations to track its own
+exports in the :term:`free-threaded build`. Creating and
+releasing a memoryview are thread-safe. Attribute access (e.g.,
+:attr:`~memoryview.shape`, :attr:`~memoryview.format`) reads fields that
+are immutable for the lifetime of the memoryview, so concurrent reads
+are safe as long as the memoryview has not been released.
+
+However, the actual data accessed through the memoryview is owned by the
+underlying object. Concurrent access to this data is only safe if the
+underlying object supports it:
+
+* For immutable objects like :class:`bytes`, concurrent reads through
+  multiple memoryviews are safe.
+
+* For mutable objects like :class:`bytearray`, reading and writing the
+  same memory region from multiple threads without external
+  synchronization is not safe and may result in data corruption.
+  Note that even read-only memoryviews of mutable objects do not
+  prevent data races if the underlying object is modified from
+  another thread.
+
+.. code-block::
+   :class: bad
+
+   # NOT safe: concurrent writes to the same buffer
+   data = bytearray(1000)
+   view = memoryview(data)
+   # Thread 1: view[0:500] = b'x' * 500
+   # Thread 2: view[0:500] = b'y' * 500
+
+.. code-block::
+   :class: good
+
+   # Safe: use a lock for concurrent access
+   import threading
+   lock = threading.Lock()
+   data = bytearray(1000)
+   view = memoryview(data)
+
+   with lock:
+       view[0:500] = b'x' * 500
+
+Resizing or reallocating the underlying object (such as calling
+:meth:`bytearray.resize`) while a memoryview is exported raises
+:exc:`BufferError`. This is enforced regardless of threading.

-   application, and initialize a Tcl interpreter for this widget.  Each
-   instance has its own associated Tcl interpreter.
-
-   The :class:`Tk` class is typically instantiated using all default values.
-   However, the following keyword arguments are currently recognized:
-
-   *screenName*
-      When given (as a string), sets the :envvar:`DISPLAY` environment
-      variable. (X11 only)
-   *baseName*
-      Name of the profile file.  By default, *baseName* is derived from the
-      program name (``sys.argv[0]``).
-   *className*
-      Name of the widget class.  Used as a profile file and also as the name
-      with which Tcl is invoked (*argv0* in *interp*).
-   *useTk*
-      If ``True``, initialize the Tk subsystem.  The :func:`tkinter.Tcl() <Tcl>`
-      function sets this to ``False``.
-   *sync*
-      If ``True``, execute all X server commands synchronously, so that errors
-      are reported immediately.  Can be used for debugging. (X11 only)
-   *use*
-      Specifies the *id* of the window in which to embed the application,
-      instead of it being created as an independent toplevel window. *id* must
-      be specified in the same way as the value for the -use option for
-      toplevel widgets (that is, it has a form like that returned by
-      :meth:`winfo_id`).
-
-      Note that on some platforms this will only work correctly if *id* refers
-      to a Tk frame or toplevel that has its -container option enabled.
-
-   :class:`Tk` reads and interprets profile files, named
-   :file:`.{className}.tcl` and :file:`.{baseName}.tcl`, into the Tcl
-   interpreter and calls :func:`exec` on the contents of
-   :file:`.{className}.py` and :file:`.{baseName}.py`.  The path for the
-   profile files is the :envvar:`HOME` environment variable or, if that
-   isn't defined, then :data:`os.curdir`.
-
-   .. attribute:: tk
-
-      The Tk application object created by instantiating :class:`Tk`.  This
-      provides access to the Tcl interpreter.  Each widget that is attached
-      the same instance of :class:`Tk` has the same value for its :attr:`tk`
-      attribute.
-
-   .. attribute:: master
-
-      The widget object that contains this widget.  For :class:`Tk`, the
-      *master* is :const:`None` because it is the main window.  The terms
-      *master* and *parent* are similar and sometimes used interchangeably
-      as argument names; however, calling :meth:`winfo_parent` returns a
-      string of the widget name whereas :attr:`master` returns the object.
-      *parent*/*child* reflects the tree-like relationship while
-      *master*/*slave* reflects the container structure.
-
-   .. attribute:: children
-
-      The immediate descendants of this widget as a :class:`dict` with the
-      child widget names as the keys and the child instance objects as the
-      values.
-
-
-.. function:: Tcl(screenName=None, baseName=None, className='Tk', useTk=False)
-
-   The :func:`Tcl` function is a factory function which creates an object much like
-   that created by the :class:`Tk` class, except that it does not initialize the Tk
-   subsystem.  This is most often useful when driving the Tcl interpreter in an
-   environment where one doesn't want to create extraneous toplevel windows, or
-   where one cannot (such as Unix/Linux systems without an X server).  An object
-   created by the :func:`Tcl` object can have a Toplevel window created (and the Tk
-   subsystem initialized) by calling its :meth:`loadtk` method.

+      The :meth:`!getvar` and :meth:`!setvar` methods give direct access to Tcl
+      variables.
+      In most code you will instead use a :class:`Variable` subclass such as
+      :class:`StringVar` or :class:`IntVar`, which wraps a Tcl variable and
+      converts its value to and from a Python type.
+
+   .. method:: register(func, subst=None, needcleanup=1)
+
+      Register the Python callable *func* as a Tcl command and return the name
+      of the new command as a string.
+      Whenever Tcl invokes that command, *func* is called; if *subst* is given,
+      it is applied to the command's arguments first.
+      This is the mechanism used internally to turn Python callbacks into the
+      command names passed to Tk options such as *command*.
+      Unless *needcleanup* is false, the command is deleted automatically when
+      the widget is destroyed.
+
+      .. versionchanged:: 3.13
+         The arguments passed to *func* are no longer converted to strings.
+
+   .. method:: deletecommand(name)
+
+      Delete the Tcl command named *name*, such as one previously returned by
+      :meth:`register`.
+
+   .. method:: nametowidget(name)
+
+      Return the widget instance corresponding to the Tk pathname *name*.
+
+   .. method:: send(interp, cmd, *args)
+
+      Send the Tcl command *cmd*, with the given *args*, to the Tcl interpreter
+      registered under the name *interp*, and return its result.
+      This is not available on all platforms.
+
+   .. method:: destroy()
+
+      Destroy this widget and all of its descendant widgets, and delete the Tcl
+      commands associated with them.
+
+   .. method:: lift(aboveThis=None)
+      :no-typesetting:
+
+   .. method:: tkraise(aboveThis=None)
+
+      Raise this widget in the stacking order so that it is drawn on top of its
+      siblings.
+      If *aboveThis* is given, the widget is moved to be just above it in the
+      stacking order instead.
+
+      :meth:`lift` is an alias of :meth:`!tkraise`.
+
+   .. method:: lower(belowThis=None)
+
+      Lower this widget in the stacking order so that it is drawn beneath its
+      siblings.
+      If *belowThis* is given, the widget is moved to be just below it in the
+      stacking order instead.
+
+      :meth:`tkraise`/:meth:`lift` and :meth:`lower` are overridden by the
+      :class:`Canvas` widget,
+      where they restack canvas items instead.
+
+   .. method:: image_names()
+
+      Return the names of all images that currently exist in the Tcl
+      interpreter.
+
+      This is overridden by the :class:`Text` widget,
+      where :meth:`!image_names` returns the names of its embedded images
+      instead.
+
+   .. method:: image_types()
+
+      Return the available image types, such as ``'photo'`` and ``'bitmap'``.
+
+   .. method:: anchor(anchor=None)
+      :no-typesetting:
+
+   .. method:: grid_anchor(anchor=None)
+
+      Set the anchor that controls where the grid is placed inside this
+      container when the container is larger than the grid and no row or column
+      has a non-zero weight.
+      *anchor* is one of the usual anchor strings, such as ``'nw'`` (the
+      default) or ``'center'``.
+      Called with no argument, this method has no effect.
+
+      :meth:`anchor` is an alias of :meth:`!grid_anchor`.

+
+      Return the bounding box, in pixels, of a region of the grid laid out in
+      this container, as a 4-tuple ``(xoffset, yoffset, width, height)``.
+      With no arguments the bounding box of the whole grid is returned.
+      If *column* and *row* are given, the box spans from the cell at row and
+      column 0 to that cell; if *col2* and *row2* are also given, it spans from
+      the cell (*column*, *row*) to the cell (*col2*, *row2*).
+
+      :meth:`bbox` is an alias of :meth:`!grid_bbox`,
+      except on :class:`Canvas`, :class:`Listbox`, :class:`Spinbox`,
+      :class:`Text`, :class:`ttk.Entry <tkinter.ttk.Entry>` and

+
+   .. method:: columnconfigure(index, cnf={}, **kw)
+      :no-typesetting:
+
+   .. method:: grid_columnconfigure(index, cnf={}, **kw)
+
+      Query or set the properties of the column (or columns) *index* of the
+      grid managed by this container.
+      *index* may be a column number; when setting options it may also be a
+      list of column numbers, the string ``'all'`` to affect every column, or
+      a child widget whose occupied columns are affected.
+      The supported options are:
+
+      *minsize*
+         The column's minimum size, in pixels.
+
+      *weight*
+         An integer setting how much of any extra space is apportioned to the
+         column.
+         A weight of ``0`` keeps the column at its requested size, and a column
+         of weight two grows twice as fast as a column of weight one.
+
+      *uniform*
+         The name of a uniform group.
+         Columns sharing a non-empty group name are kept in sizes that are
+         strictly proportional to their weights.
+
+      *pad*
+         Extra space, in pixels, added to the largest widget in the column when
+         computing the column's size.
+
+      With a single option name, return that option's value; with no options,
+      return a dictionary of all of them.

+
+   .. method:: rowconfigure(index, cnf={}, **kw)

+   .. method:: grid_rowconfigure(index, cnf={}, **kw)
+
+      Query or set the properties of the row (or rows) *index* of the grid
+      managed by this container.
+      *index* is interpreted as for :meth:`grid_columnconfigure`, and the
+      supported options (*minsize*, *weight*, *uniform* and *pad*) are the
+      same, applied to a row instead of a column.
+
+      :meth:`rowconfigure` is an alias of :meth:`!grid_rowconfigure`.
+
+   .. method:: grid_location(x, y)
+
+      Return the ``(column, row)`` of the grid cell that contains the pixel at
+      position (*x*, *y*), given in pixels relative to this container.
+      For locations above or to the left of the grid, ``-1`` is returned for
+      the corresponding coordinate.
+
+   .. method:: grid_propagate()
+               grid_propagate(flag)
+
+      Enable or disable geometry propagation for this container when it manages
+      its children with the grid geometry manager.
+      When *flag* is true, the container resizes itself to fit the requested
+      sizes of its children; when it is false, its size is left under your
+      control.
+      Called with no argument, return the current setting as a boolean.
+
+   .. method:: size()
+      :no-typesetting:
+
+   .. method:: grid_size()
+
+      Return the size of the grid managed by this container as a

+
+      :meth:`size` is an alias of :meth:`!grid_size`,
+      except on :class:`Listbox` and

+      which provide their own :meth:`!size` method.
+
+   .. method:: grid_slaves(row=None, column=None)
+
+      Return a list of the child widgets managed in this container's grid, most
+      recently managed first.
+      If *row* or *column* is given, only the children in that row or column
+      are returned.
+
+   .. method:: grid_content(row=None, column=None)
+

+
+   The methods with the ``bind`` and ``unbind`` prefixes associate event
+   patterns with callbacks and remove those associations.
+
+   .. method:: bind(sequence=None, func=None, add=None)
+
+      Bind the event pattern *sequence* on this widget to the callable *func*.
+
+      *sequence* is an event pattern, such as ``'<Button-1>'`` (a mouse click)
+      or ``'<KeyPress-a>'``, optionally a concatenation of several such
+      patterns that must occur shortly after one another.
+      When the event occurs, *func* is called with an :class:`Event` instance
+      describing it as its only argument; if *func* returns the string
+      ``'break'``, no further bindings for the event are invoked.
+
+      If *add* is true, *func* is added to any functions already bound to
+      *sequence*; otherwise it replaces them.
+      The binding applies only to this widget.
+
+      :meth:`!bind` returns a string identifier (a *funcid*) that can later be
+      passed to :meth:`unbind` to remove the binding without leaking the
+      associated Tcl command.
+
+      If *func* is omitted, return the binding currently associated with
+      *sequence*; if *sequence* is also omitted, return a list of all the
+      sequences for which bindings exist on this widget.
+
+   .. method:: bind_class(className, sequence=None, func=None, add=None)
+
+      Like :meth:`bind`, but bind *func* to the binding tag *className* rather
+      than to a single widget, so that the binding applies to every widget
+      having that tag.
+      *className* is usually the name of a widget class, such as ``'Button'``,
+      in which case the binding affects all widgets of that class.
+      The set of binding tags for a widget can be inspected and changed with
+      :meth:`bindtags`.
+
+      The remaining arguments and the return value are as for :meth:`bind`.
+
+   .. method:: bind_all(sequence=None, func=None, add=None)
+
+      Like :meth:`bind`, but bind *func* to the special binding tag ``'all'``,
+      so that the binding applies to every widget in the application.
+
+      The remaining arguments and the return value are as for :meth:`bind`.
+
+   .. method:: unbind(sequence, funcid=None)
+
+      Remove bindings for the event pattern *sequence* on this widget.
+
+      If *funcid* is given, only the function identified by it (a value
+      returned from a previous call to :meth:`bind`) is removed, and its
+      associated Tcl command is deleted.
+      Otherwise all bindings for *sequence* are destroyed, leaving it unbound.
+
+      .. versionchanged:: 3.13
+         If *funcid* is given, only that callback is unbound; other callbacks
+         bound to *sequence* are kept.
+
+
+   .. method:: unbind_class(className, sequence)
+
+      Remove all bindings for the event pattern *sequence* from the binding tag
+      *className*.
+      See :meth:`bind_class`.
+
+   .. method:: unbind_all(sequence)
+
+      Remove all bindings for the event pattern *sequence* from the special
+      binding tag ``'all'``.
+      See :meth:`bind_all`.
+
+   .. method:: bindtags(tagList=None)
+
+      If *tagList* is omitted, return a tuple of the binding tags associated
+      with this widget.
+      When an event occurs in a widget, it is applied to each of the widget's
+      binding tags in order, and for each tag the most specific matching
+      binding is executed.
+      By default a widget has four binding tags: its own pathname, its widget
+      class, the pathname of its nearest toplevel ancestor, and ``'all'``, in
+      that order.
+
+      If *tagList* is given, it must be a sequence of strings; the widget's
+      binding tags are set to its elements, which determines the order in which
+      bindings are evaluated.
+
+   The methods with the ``event_`` prefix define virtual events and generate
+   events programmatically.
+
+   .. method:: event_add(virtual, *sequences)
+
+      Associate the virtual event *virtual*, whose name has the form
+      ``'<<Paste>>'``, with each of the physical event patterns given by
+      *sequences*, so that the virtual event triggers whenever any of them
+      occurs.
+      If *virtual* is already defined, the new sequences are added to its
+      existing ones.
+
+   .. method:: event_delete(virtual, *sequences)
+
+      Remove each of *sequences* from those associated with the virtual event
+      *virtual*.
+      Sequences that are not currently associated with *virtual* are ignored.
+      If no *sequences* are given, all physical event sequences are removed, so
+      that *virtual* no longer triggers.
+
+   .. method:: event_generate(sequence, **kw)
+
+      Generate the event *sequence* on this widget and arrange for it to be
+      processed just as if it had come from the window system.
+      *sequence* must be a single event pattern, such as ``'<Button-1>'`` or
+      ``'<<Paste>>'``, not a concatenation of several.
+      Keyword arguments specify additional fields of the event, for example *x*
+      and *y* for the pointer position, or *when* to control when the event is
+      processed; refer to the Tk ``event`` manual page for the full list.
+
+   .. method:: event_info(virtual=None)
+
+      If *virtual* is omitted, return a tuple of all the virtual events that
+      are currently defined.
+      If *virtual* is given, return a tuple of the physical event sequences
+      currently associated with it, or an empty tuple if it is not defined.
+
+   The methods with the ``after`` prefix schedule callbacks to run after a
+   delay or when the application is idle.
+
+   .. method:: after(ms, func=None, *args, **kw)
+
+      Schedule the callable *func* to be called after *ms* milliseconds, with
+      *args* and *kw* passed to it as positional and keyword arguments.
+      Return an identifier that can be passed to :meth:`after_cancel` to cancel
+      the call.
+
+      If *func* is omitted, sleep for *ms* milliseconds instead, processing no
+      events during that time, and return ``None``.
+
+      .. versionchanged:: 3.10
+         *func* can now be any callable object, not only a function.
+
+      .. versionchanged:: 3.14
+         Keyword arguments are now passed to *func*.
+
+
+   .. method:: after_cancel(id)
+
+      Cancel a callback previously scheduled with :meth:`after` or
+      :meth:`after_idle`.
+      *id* must be an identifier returned by one of those methods; passing a
+      value that is not such an identifier raises :exc:`ValueError`.
+      If the callback has already run or been cancelled, this has no effect.
+
+      .. versionchanged:: 3.7
+         Passing ``None`` (or any false value) as *id* now raises
+         :exc:`ValueError`.
+
+
+   .. method:: after_idle(func, *args, **kw)
+
+      Schedule the callable *func* to be called, with *args* and *kw* passed to
+      it, when the Tk main loop next becomes idle, that is, when it has no
+      other events to process.
+      Return an identifier that can be passed to :meth:`after_cancel` to cancel
+      the call.
+
+      .. versionchanged:: 3.14
+         Keyword arguments are now passed to *func*.
+
+
+   .. method:: after_info(id=None)
+
+      If *id* is omitted, return a tuple of the identifiers of all callbacks
+      currently scheduled with :meth:`after` and :meth:`after_idle` for this
+      interpreter.
+
+      If *id* is given, it must identify a callback that has not yet run or
+      been cancelled, and the return value is a tuple ``(script, type)``, where
+      *script* refers to the function to be called and *type* is either
+      ``'idle'`` or ``'timer'``.
+      A :exc:`TclError` is raised if *id* does not exist.
+
+      .. versionadded:: 3.13
+
+
+   .. method:: mainloop(n=0)
+
+      Enter the Tk event loop, which processes events until all windows are
+      destroyed.
+      This is normally called once, on the root window, to run the application.
+
+   .. method:: quit()
+
+      Quit the Tcl interpreter, causing :meth:`mainloop` to return.
+
+   .. method:: update()
+
+      Enter the event loop until all pending events, including idle callbacks,
+      have been processed.
+      This brings the display up to date and handles any events that are
+      already queued, then returns.
+
+   .. method:: update_idletasks()
+
+      Enter the event loop until all pending idle callbacks have been called.
+      This updates the display of windows, for example after geometry changes,
+      but does not process events caused by the user.
+
+   .. method:: waitvar(name)
+      :no-typesetting:
+
+   .. method:: wait_variable(name)
+
+      Wait until the Tcl variable *name* is modified, continuing to process
+      events in the meantime so that the application stays responsive.
+      *name* is usually a :class:`Variable` instance, such as an
+      :class:`IntVar` or :class:`StringVar`.
+
+      :meth:`waitvar` is an alias of :meth:`!wait_variable`.
+
+   .. method:: wait_window(window=None)
+
+      Wait until *window* is destroyed, continuing to process events in the
+      meantime.
+      If *window* is omitted, this widget is used.
+      This is typically used to wait for the user to finish interacting with a
+      dialog box.
+
+   .. method:: wait_visibility(window=None)
+
+      Wait until the visibility state of *window* changes, for example when it
+      first appears on the screen, continuing to process events in the
+      meantime.
+      If *window* is omitted, this widget is used.
+      This is typically used to wait for a newly created window to become
+      visible before acting on it.
+
+   The methods with the ``focus_`` prefix manage the keyboard focus.
+
+   .. method:: focus_set()
+      :no-typesetting:
+
+   .. method:: focus()
+
+      Direct the keyboard input focus for this widget's display to this widget.
+      If the application does not currently have the input focus on this
+      widget's display, the widget is remembered as the focus window for its
+      top level, and the focus will be redirected to it the next time the
+      window manager gives the focus to the top level.
+      :meth:`focus` is an alias of :meth:`!focus_set`,
+      except on the :class:`Canvas` and
+      :class:`ttk.Treeview <tkinter.ttk.Treeview>` widgets,
+      which provide their own :meth:`!focus` method.
+
+   .. method:: focus_force()
+
+      Direct the keyboard input focus to this widget even if the application
+      does not currently have the input focus for the widget's display.
+      This method should be used sparingly, if at all; normally an application
+      should wait for the window manager to give it the focus rather than
+      claiming it.
+
+   .. method:: focus_get()
+
+      Return the widget that currently has the keyboard focus in the
+      application, or ``None`` if no widget in the application has the focus.
+      Use :meth:`focus_displayof` to work correctly with several displays.
+
+   .. method:: focus_displayof()
+
+      Return the widget that currently has the keyboard focus on the display
+      where this widget is located, or ``None`` if no widget in the application
+      has the focus on that display.
+
+   .. method:: focus_lastfor()
+
+      Return the most recent widget to have had the keyboard focus among all
+      the widgets in the same top level as this widget; this is the widget that
+      will receive the focus the next time the window manager gives the focus
+      to the top level.
+      If no widget in that top level has ever had the focus, or if the most
+      recent focus widget has been deleted, the top level itself is returned.
+
+   .. method:: tk_focusFollowsMouse()
+
+      Reconfigure Tk to use an implicit focus model in which the focus is set
+      to a widget whenever the mouse pointer enters it.
+      This cannot easily be disabled once enabled.
+
+   .. method:: tk_focusNext()
+
+      Return the next widget after this one in the keyboard traversal order, or
+      ``None`` if there is none.
+      The traversal order goes first to the next child, then recursively to the
+      children of that child, and then to the next sibling higher in the
+      stacking order.
+      A widget is skipped if its ``takefocus`` option is set to ``0``.
+      This method is used in the default bindings for the :kbd:`Tab` key.
+
+   .. method:: tk_focusPrev()
+
+      Return the previous widget before this one in the keyboard traversal
+      order, or ``None`` if there is none.
+      See :meth:`tk_focusNext` for how the order is defined.
+      This method is used in the default bindings for the :kbd:`Shift-Tab` key.
+
+   The methods with the ``grab_`` prefix set and query the input grab, which
+   directs all input events to a single widget.
+
+   .. method:: grab_set()
+
+      Set a local grab on this widget.
+      A grab confines pointer events to this widget and its descendants: while
+      the pointer is outside the widget's subtree, button presses and releases
+      and pointer motion are reported to the grab widget, and windows outside
+      the subtree become insensitive until the grab is released.
+      A local grab affects only the grabbing application.
+      Any grab previously set by this application on the widget's display is
+      automatically released.
+      Setting a grab is the usual way to make a dialog modal: while the grab is
+      in effect the user cannot interact with the other windows of the
+      application.
+
+   .. method:: grab_set_global()
+
+      Set a global grab on this widget.
+      A global grab is like the local grab set by :meth:`grab_set`, but it
+      locks out all other applications on the screen, so that only this
+      widget's subtree is sensitive to pointer events, and it also grabs the
+      keyboard.
+      Use with caution: it is easy to render a display unusable with a global
+      grab, since other applications stop receiving events until it is
+      released.
+
+   .. method:: grab_release()
+
+      Release the grab on this widget if there is one; otherwise do nothing.
+
+   .. method:: grab_current()
+
+      Return the widget that currently holds the grab in this application for
+      this widget's display, or ``None`` if there is no such widget.
+
+   .. method:: grab_status()
+
+      Return ``None`` if no grab is currently set on this widget, ``"local"``
+      if a local grab is set, or ``"global"`` if a global grab is set.
+
+   The methods with the ``selection_`` prefix retrieve and manage the X
+   selection.
+
+   .. method:: selection_clear(**kw)
+
+      Clear the X selection, so that no window owns it anymore.
+      The selection to clear is given by the keyword argument *selection*, an
+      atom name such as ``'PRIMARY'`` or ``'CLIPBOARD'``; it defaults to
+      ``PRIMARY``.
+      The *displayof* keyword argument names a widget that determines the
+      display on which to operate, and defaults to this widget.
+
+      This is overridden by the :class:`Entry`, :class:`Listbox` and
+      :class:`Spinbox` widgets,
+      where :meth:`!selection_clear` clears the widget's own selection instead.
+
+   .. method:: selection_get(**kw)
+
+      Return the contents of the current X selection.
+      The keyword argument *selection* names the selection and defaults to
+      ``PRIMARY``.
+      The keyword argument *type* specifies the form in which the data is to be
+      returned (the desired conversion target), an atom name such as
+      ``'STRING'`` or ``'FILE_NAME'``; it defaults to ``STRING``, except on
+      X11, where ``UTF8_STRING`` is tried first and ``STRING`` is used as a
+      fallback.
+      The *displayof* keyword argument names a widget that determines the
+      display from which to retrieve the selection, and defaults to this
+      widget.
+
+   .. method:: selection_handle(command, **kw)
+
+      Register *command* as a handler to supply the X selection owned by this
+      widget when another application requests it.
+      When the selection is retrieved, *command* is called with two arguments,
+      the starting character offset and the maximum number of characters to
+      return, and must return at most that many characters of the selection
+      starting at that offset; for very long selections it is called repeatedly
+      with increasing offsets.
+      The keyword argument *selection* names the selection (default
+      ``PRIMARY``) and the keyword argument *type* gives the form of the
+      selection that the handler supplies (such as ``'STRING'`` or
+      ``'FILE_NAME'``, default ``STRING``).
+
+   .. method:: selection_own(**kw)
+
+      Make this widget the owner of the X selection on its display.
+      The previous owner, if any, is notified that it has lost the selection.
+      The keyword argument *selection* names the selection and defaults to
+      ``PRIMARY``.
+
+   .. method:: selection_own_get(**kw)
+
+      Return the widget in this application that owns the X selection on the
+      display containing this widget, or ``None`` if no widget in this
+      application owns the selection.
+      The keyword argument *selection* names the selection and defaults to
+      ``PRIMARY``.
+      The *displayof* keyword argument names a widget that determines the
+      display to query, and defaults to this widget.
+
+   The methods with the ``clipboard_`` prefix manage the clipboard.
+
+   .. method:: clipboard_append(string, **kw)
+
+      Append *string* to the Tk clipboard and claim ownership of the clipboard
+      on this widget's display.
+      Before appending, the clipboard should be emptied with
+      :meth:`clipboard_clear`; all appends should be completed before returning
+      to the event loop so that the clipboard is updated atomically.
+      The keyword argument *type* specifies the form of the data, an atom name
+      such as ``'STRING'`` or ``'FILE_NAME'`` (default ``STRING``), and the
+      keyword argument *format* specifies the representation used to transmit
+      it (default ``STRING``).
+      The *displayof* keyword argument names a widget that determines the
+      target display, and defaults to this widget.
+      The contents can be retrieved with :meth:`clipboard_get` or
+      :meth:`selection_get`.
+
+   .. method:: clipboard_clear(**kw)
+
+      Claim ownership of the clipboard on this widget's display and remove any
+      previous contents.
+      The *displayof* keyword argument names a widget that determines the
+      target display, and defaults to this widget.
+
+   .. method:: clipboard_get(**kw)
+
+      Retrieve data from the clipboard on this widget's display.
+      The keyword argument *type* specifies the form in which the data is to be
+      returned, an atom name such as ``'STRING'`` or ``'FILE_NAME'``; it
+      defaults to ``STRING``, except on X11, where ``UTF8_STRING`` is tried
+      first and ``STRING`` is used as a fallback.
+      The *displayof* keyword argument names a widget that determines the
+      display, and defaults to the root window of the application.
+      This is equivalent to ``selection_get(selection='CLIPBOARD')``.
+
+   The methods with the ``option_`` prefix query and modify the Tk option
+   database.
+
+   .. method:: option_add(pattern, value, priority=None)
+
+      Add an option to the Tk option database that associates *value* with
+      *pattern*.
+      *pattern* consists of names and/or classes separated by asterisks or
+      dots, in the usual X format.
+      *priority* is an integer between 0 and 100, or one of the symbolic names
+      ``'widgetDefault'`` (20), ``'startupFile'`` (40), ``'userDefault'`` (60),
+      or ``'interactive'`` (80); it defaults to ``interactive``.
+
+   .. method:: option_clear()
+
+      Clear the Tk option database.
+      Default options from the :envvar:`!RESOURCE_MANAGER` property or the
+      :file:`.Xdefaults` file are reloaded automatically the next time an
+      option is added to or removed from the database.
+
+   .. method:: option_get(name, className)
+
+      Return the value of the option matching this widget under *name* and
+      *className* from the Tk option database, or an empty string if there is
+      no matching entry.
+      When several entries match, the one with the highest priority is
+      returned, and among entries of equal priority the most recently added
+      one.
+
+   .. method:: option_readfile(fileName, priority=None)
+
+      Read the file named *fileName*, which should have the standard format for
+      an X resource database such as :file:`.Xdefaults`, and add all the
+      options it specifies to the Tk option database.
+      *priority* is interpreted as for :meth:`option_add` and defaults to
+      ``interactive``.
+
+   .. method:: bell(displayof=0)
+
+      Ring the bell on the display for this widget, using the display's current
+      bell-related settings, and reset the screen saver for the screen.
+      If *displayof* is given as a widget, the bell is rung on that widget's
+      display instead.
+
+   .. method:: tk_setPalette(background, /)
+               tk_setPalette(*args, **kw)
+
+      Set a new color scheme for all Tk widget elements.
+      Existing widgets are updated and the option database is changed so that
+      future widgets use the new colors.
+      A single color argument is taken as the normal background color, from
+      which a complete palette is computed.
+      Alternatively, the arguments may be given as keyword *name*/*value* pairs
+      naming individual options in the option database.
+      The recognized option names are ``activeBackground``,
+      ``activeForeground``, ``background``, ``disabledForeground``,
+      ``foreground``, ``highlightBackground``, ``highlightColor``,
+      ``insertBackground``, ``selectColor``, ``selectBackground``,
+      ``selectForeground``, and ``troughColor``; reasonable defaults are
+      computed for any that are not specified.
+
+   .. method:: tk_bisque()
+
+      Restore the application's colors to the light brown (bisque) color scheme
+      used in Tk 3.6 and earlier versions.
+      Provided for backward compatibility.
+
+   .. method:: tk_strictMotif(boolean=None)
+
+      Query or set whether Tk's look and feel should strictly adhere to Motif.
+      A true *boolean* value enables strict Motif compliance (for example, no
+      color change when the mouse passes over a slider).
+      Return the resulting setting.
+
+   .. method:: tk_appname(name=None)
+
+      Query or set the name used to communicate with this application through
+      the ``send`` command.
+      With no argument, return the current name; otherwise change it to *name*
+      and return the actual name set, which may have a suffix appended to keep
+      it unique among the applications on the display.
+
+      .. versionadded:: next
+
+   .. method:: tk_useinputmethods(boolean=None, *, displayof=0)
+
+      Query or set whether Tk uses the X Input Methods (XIM) for filtering
+      events, and return the resulting state.
+      This is significant only on X11; if XIM support is not available it
+      always returns ``False``.
+
+      .. versionadded:: next
+
+   .. method:: tk_caret(*, x=None, y=None, height=None)
+
+      Set or query the caret location for the widget's display.
+      The caret is the per-display insertion position used for global focus
+      indication (for accessibility) and for placing the input method
+      (XIM or IME) window.
+      With no argument, return the current location as a dictionary with the
+      keys ``'x'``, ``'y'`` and ``'height'``; otherwise update the given
+      coordinates.
+
+      .. versionadded:: next
+
+   .. method:: tk_scaling(number=None, *, displayof=0)
+
+      Query or set the scaling factor used by Tk to convert between physical
+      units (such as points, inches or millimeters) and pixels, expressed as
+      the number of pixels per point (where a point is 1/72 inch).
+      With no argument, return the current factor; otherwise set it to the
+      floating-point *number*.
+
+      .. versionadded:: next
+
+   .. method:: tk_inactive(reset=False, *, displayof=0)
+
+      Return the number of milliseconds since the last time the user interacted
+      with the system, or ``-1`` if the windowing system does not support this.
+      If *reset* is true, reset the inactivity timer to zero instead and return
+      ``None``.
+
+      .. versionadded:: next
+
+   The methods with the ``busy_`` prefix manage the busy state of a window,
+   which shows a busy cursor and ignores user input.

+   .. method:: tk_busy(**kw)
+      :no-typesetting:
+
+   .. method:: tk_busy_hold(**kw)
+
+      Make this widget appear busy.
+      A transparent window is placed in front of the widget, so that it and all
+      of its descendants in the widget hierarchy are blocked from pointer
+      events and display a busy cursor.
+      Normally :meth:`update` should be called immediately afterwards to ensure
+      that the hold operation is in effect before the application starts its
+      processing.
+
+      The only supported configuration option is *cursor*, the cursor to be
+      displayed while the widget is busy; it may have any of the values
+      accepted by :meth:`!configure`.
+
+      :meth:`busy_hold`, :meth:`busy` and :meth:`tk_busy` are aliases of
+      :meth:`!tk_busy_hold`.

+      :no-typesetting:
+
+   .. method:: tk_busy_configure(cnf=None, **kw)
+
+      Query or modify the configuration options of the busy window.
+      The widget must have been previously made busy by :meth:`tk_busy_hold`.
+      With no arguments, return a dictionary describing all of the available
+      options; if *cnf* is the name of an option, return a tuple describing
+      that one option.
+      Otherwise set the given options to the given values.
+      Options may have any of the values accepted by :meth:`tk_busy_hold`.
+
+      The option database is referenced through the widget name or class.
+      For example, if a :class:`Frame` widget named ``frame`` is to be made
+      busy, the busy cursor can be specified for it by either of the calls::
+
+         w.option_add('*frame.busyCursor', 'gumby')
+         w.option_add('*Frame.BusyCursor', 'gumby')
+
+      :meth:`busy_configure`, :meth:`busy_config` and :meth:`tk_busy_config`

+      :no-typesetting:
+
+   .. method:: tk_busy_cget(option)
+
+      Return the current value of the busy configuration *option*.
+      The widget must have been previously made busy by :meth:`tk_busy_hold`,
+      and *option* may have any of the values accepted by that method.
+
+      :meth:`busy_cget` is an alias of :meth:`!tk_busy_cget`.

+      :no-typesetting:
+
+   .. method:: tk_busy_forget()
+
+      Make this widget no longer busy, releasing the resources (including the
+      transparent window) allocated when it was made busy.
+      User events will again be received by the widget.
+      These resources are also released when the widget is destroyed.
+
+      :meth:`busy_forget` is an alias of :meth:`!tk_busy_forget`.
+
+      .. versionadded:: 3.13
+
+
+   .. method:: busy_status()

+
+      :meth:`busy_current` is an alias of :meth:`!tk_busy_current`.
+
+      .. versionadded:: 3.13
+
+   The methods with the ``winfo_`` prefix retrieve information about windows
+   managed by Tk.
+
+   .. method:: winfo_atom(name, displayof=0)
+
+      Return the integer identifier for the atom whose name is *name*, creating
+      a new atom if none exists.
+      If *displayof* is given, the atom is looked up on the display of that
+      window; otherwise it is looked up on the display of the application's
+      main window.
+
+   .. method:: winfo_atomname(id, displayof=0)
+
+      Return the textual name for the atom whose integer identifier is *id*.
+      This is the inverse of :meth:`winfo_atom`.
+      If *displayof* is given, the identifier is looked up on the display of

+
+   .. method:: winfo_containing(rootX, rootY, displayof=0)
+
+      Return the widget containing the point given by *rootX* and *rootY*, or
+      ``None`` if no window in this application contains the point.
+      The coordinates are in screen units in the coordinate system of the root
+      window.
+      If *displayof* is given, the coordinates refer to the screen containing
+      that window; otherwise they refer to the screen of the application's main
+      window.
+
+   .. method:: winfo_depth()
+
+      Return the depth of the widget, that is, the number of bits per pixel.
+
+   .. method:: winfo_exists()
+
+      Return ``1`` if the widget exists, ``0`` otherwise.
+
+   .. method:: winfo_fpixels(number)
+
+      Return a floating-point value giving the number of pixels in the widget
+      corresponding to the screen distance *number* (for example,

+      All dimensions are in pixels.
+      An offset can be negative; see :meth:`~Wm.geometry`.
+
+   .. method:: winfo_height()
+
+      Return the height of the widget in pixels.
+      When a window is first created its height is 1 pixel; it is eventually

+      See also :meth:`winfo_reqheight`.
+
+   .. method:: winfo_id()
+
+      Return a low-level platform-specific identifier for the widget.
+      On Unix this is the X window identifier, and on Windows it is the window
+      handle.
+
+   .. method:: winfo_interps(displayof=0)
+
+      Return a tuple of the names of all Tcl interpreters currently registered
+      for a particular display.
+      If *displayof* is given, the return value refers to the display of that

+      widget is the main window of the application.
+
+   .. method:: winfo_pathname(id, displayof=0)
+
+      Return the path name of the window whose identifier is *id*.
+      If *displayof* is given, the identifier is looked up on the display of

+
+   .. method:: winfo_pixels(number)
+
+      Return the number of pixels in the widget corresponding to the screen
+      distance *number* (for example, ``"2.0c"`` or ``"1i"``).

+
+   .. method:: winfo_pointerx()
+
+      Return the pointer's *x* coordinate, in pixels, relative to the screen's

+      geometry.
+
+   .. method:: winfo_reqwidth()
+
+      Return the widget's requested width in pixels.
+      This is the value used by the widget's geometry manager to compute its

+
+   .. method:: winfo_toplevel()
+
+      Return the top-of-hierarchy window containing the widget.
+      In standard Tk this is always a :class:`Toplevel` widget.
+
+   .. method:: winfo_viewable()
+
+      Return ``1`` if the widget and all of its ancestors up through the
+      nearest toplevel window are mapped, ``0`` otherwise.
+

+
+   .. method:: winfo_visualsavailable(includeids=False)
+
+      Return a list describing the visuals available for the widget's screen.
+      Each item consists of a visual class (see :meth:`winfo_visual`) followed

+      included.
+
+   .. method:: winfo_vrootheight()

+
+   .. method:: winfo_vrootx()
+
+      Return the *x* offset of the virtual root window associated with the

+
+   .. method:: winfo_vrooty()
+
+      Return the *y* offset of the virtual root window associated with the

+      See also :meth:`winfo_reqwidth`.
+
+   .. method:: winfo_x()
+
+      Return the *x* coordinate, in the widget's parent, of the upper-left

+      as :data:`sys.version_info`: *major*, *minor*, *micro*, *releaselevel*
+      and *serial*.
+      *releaselevel* is ``'alpha'``, ``'beta'`` or ``'final'``.
+      Converting it to a string gives the version in the usual Tcl/Tk notation,
+      for example ``'9.0.3'`` for a final release or ``'9.1b2'`` for a

+
+
+.. class:: Wm()
+
+   The :class:`!Wm` mixin provides access to the window manager, allowing an
+   application to control such things as the title, geometry and icon of a
+   top-level window, the way it is resized, and how it responds to window
+   manager protocols.
+   It is mixed into :class:`Tk` and :class:`Toplevel`, so its methods are
+   available on every top-level window.
+   Each method has two equivalent spellings: a short name and a
+   ``wm_``-prefixed name (for example, :meth:`title` and :meth:`wm_title`).
+
+   .. method:: wm_aspect(minNumer=None, minDenom=None, maxNumer=None, maxDenom=None)
+      :no-typesetting:
+
+   .. method:: aspect(minNumer=None, minDenom=None, maxNumer=None, maxDenom=None)
+
+      Constrain the aspect ratio (the ratio of width to height) of the window.
+      If all four arguments are given, the window manager keeps the ratio
+      between ``minNumer/minDenom`` and ``maxNumer/maxDenom``; passing empty
+      strings removes any existing restriction.
+      With no arguments, return a tuple of the four current values, or an empty
+      string if no aspect restriction is in effect.
+      :meth:`wm_aspect` is an alias of :meth:`!aspect`.

+   .. method:: wm_attributes(*args, return_python_dict=False, **kwargs)
+      :no-typesetting:
+
+   .. method:: attributes(*args, return_python_dict=False, **kwargs)
+
+      Query or set platform-specific attributes of the window.
+      With no arguments, return the platform-specific flags and their values;
+      pass *return_python_dict* as true to get them as a dictionary.
+      A single option name such as ``'alpha'`` returns the value of that
+      option, and options are set using keyword arguments (``alpha=0.5``).
+
+      The available attributes differ by platform.
+      All platforms support:
+
+      *alpha*
+         The window's opacity, from ``0.0`` (fully transparent) to ``1.0``
+         (opaque).
+         Where transparency is unsupported the value stays at ``1.0``.
+
+      *appearance*
+         Whether the window is rendered in dark mode on Windows and macOS:
+         ``'auto'``, ``'light'`` or ``'dark'`` (this has no effect on X11).
+
+      *fullscreen*
+         Whether the window takes up the entire screen and has no borders.
+
+      *topmost*
+         Whether the window is displayed above all other windows.
+
+      Windows additionally supports:
+
+      *disabled*
+         Whether the window is in a disabled state.
+
+      *toolwindow*
+         Whether the window uses the tool window style.
+
+      *transparentcolor*
+         The color that is made fully transparent, or an empty string for none.
+
+      macOS additionally supports:
+
+      *class*
+         Whether the underlying Aqua window is an ``nswindow`` or an
+         ``nspanel``; this can only be set before the window is created.
+
+      *modified*
+         The modification state shown by the window's close button and proxy
+         icon.
+
+      *notify*
+         Whether the application's dock icon bounces to request attention.
+
+      *stylemask*
+         The style mask of the underlying Aqua window, given as a list of bit
+         names such as ``titled`` or ``resizable``.
+
+      *tabbingid*
+         The identifier of the tab group that the window belongs to.
+
+      *tabbingmode*
+         Whether the window may be opened as a tab: ``'auto'``, ``'preferred'``
+         or ``'disallowed'``.
+
+      *titlepath*
+         The path of the file represented by the window's proxy icon.
+
+      *transparent*
+         Whether the content area is transparent and the window shadow is
+         turned off.
+
+      X11 additionally supports:
+
+      *type*
+         The window type, or a list of types in order of preference, that the
+         window manager should use to interpret the window, such as
+         ``'dialog'`` or ``'splash'``.
+
+      *zoomed*
+         Whether the window is maximized.
+
+      .. note::
+
+         Tk 8.6 added the *type* attribute, and Tk 9.0 added the *appearance*,
+         *class*, *stylemask*, *tabbingid* and *tabbingmode* attributes.
+
+      On X11 changes are applied asynchronously, so a queried value may not yet
+      reflect the most recent request.
+      :meth:`wm_attributes` is an alias of :meth:`!attributes`.
+
+      .. versionchanged:: 3.13

+         ``-``, and attributes may be set using keyword arguments.
+         The *return_python_dict* parameter was added.
+
+      .. deprecated:: 3.13
+         Setting an attribute by passing the option name (with a leading
+         ``-``) and its value as two positional arguments, as in
+         ``w.attributes('-alpha', 0.5)``, is deprecated; use keyword arguments

+
+   .. method:: colormapwindows(*wlist)
+
+      Manipulate the ``WM_COLORMAP_WINDOWS`` property, which tells the window
+      manager about windows that have private colormaps.
+      If *wlist* is given, overwrite the property with those windows (their

+      :no-typesetting:
+
+   .. method:: deiconify()
+
+      Display the window in normal (non-iconified) form by mapping it.
+      If the window has never been mapped, this ensures it appears de-iconified
+      when it is first mapped.
+      On Windows the window is also raised and given the focus.
+      :meth:`wm_deiconify` is an alias of :meth:`!deiconify`.
+
+   .. method:: wm_focusmodel(model=None)
+      :no-typesetting:
+
+   .. method:: focusmodel(model=None)
+
+      Set or query the focus model for the window.
+      *model* is either ``'active'`` (the window claims the input focus for
+      itself or its descendants, even when the focus is in another application)
+      or ``'passive'`` (the window relies on the window manager to give it the
+      focus).
+      With no argument, return the current model.
+      The default is ``'passive'``, which is what the :meth:`!focus` command
+      assumes.
+      :meth:`wm_focusmodel` is an alias of :meth:`!focusmodel`.
+
+   .. method:: wm_forget(window)

+
+   .. method:: forget(window)
+
+      Unmap *window* from the screen so that it is no longer managed by the
+      window manager.
+      A :class:`Toplevel` is then treated like a :class:`Frame`, although its
+      ``-menu`` configuration is remembered and the menu reappears if the
+      widget is managed again.
+      :meth:`wm_forget` is an alias of :meth:`!forget`.
+
+      Not to be confused with :meth:`Pack.forget`.

+
+   .. method:: wm_frame()
+      :no-typesetting:
+
+   .. method:: frame()
+
+      Return the platform-specific window identifier for the outermost

+      :no-typesetting:
+
+   .. method:: geometry(newGeometry=None)
+
+      Set or query the geometry of the window.
+      *newGeometry* has the form ``=widthxheight+x+y``, where any of ``=``,
+      ``widthxheight`` and the ``+x+y`` position may be omitted.
+      *width* and *height* are in pixels (or grid units for a gridded window);
+      a position preceded by ``+`` is measured from the left or top edge of the
+      screen and one preceded by ``-`` from the right or bottom edge.
+      An offset can be negative, as in ``'200x100+-9+-8'``, when the window
+      edge is positioned beyond the corresponding screen edge.
+      An empty string cancels any user-specified geometry, letting the window
+      revert to its natural size.
+      With no argument, return the current geometry as a string of the form
+      ``'200x200+10+10'``.

+
+      Manage the window as a gridded window and define the relationship between
+      grid units and pixels.
+      *baseWidth* and *baseHeight* are the numbers of grid units for the
+      window's internally requested size, and *widthInc* and *heightInc* are
+      the pixel sizes of a horizontal and vertical grid unit.
+      Empty strings turn off gridded management.
+      With no arguments, return a tuple of the four current values, or an empty
+      string if the window is not gridded.
+      :meth:`wm_grid` is an alias of :meth:`!grid`.

+
+   .. method:: group(pathName=None)
+
+      Set or query the leader of a group of related windows.
+      *pathName* gives the path name of the group leader; the window manager
+      may, for example, unmap all windows in the group when the leader is
+      iconified.
+      An empty string removes the window from any group.
+      With no argument, return the path name of the current group leader, or an

+      *badge* may be a positive integer (for example a count of unread
+      messages) or an exclamation point to denote that attention is needed;
+      an empty string removes the badge.
+      On X11 the variable ``::tk::icons::base_icon(window)`` must be set to the

+
+      Set or query the bitmap used by the window manager for the window's icon.
+      *bitmap* names a bitmap in one of the standard forms accepted by Tk; an
+      empty string cancels the current icon bitmap.
+      With no argument, return the name of the current icon bitmap, or an empty

+      When the window is iconified, *pathName* is mapped to serve as its icon
+      and unmapped again when it is de-iconified.
+      An empty string cancels the association.

+
+   Geometry manager that arranges widgets by packing them against the sides of

+      The supported options are:
+
+      *side*
+         Which side of the container to pack the widget against: ``'top'`` (the
+         default), ``'bottom'``, ``'left'`` or ``'right'``.
+
+      *fill*
+         Whether to stretch the widget to fill its parcel: ``'none'`` (the

+
+      *expand*
+         Whether the widget should expand to consume any extra space in its

+
+      *anchor*
+         Where to position the widget in its parcel when the parcel is larger

+
+      *ipadx*, *ipady*
+         Internal padding added on the left and right (*ipadx*) or top and

+         External padding left on the left and right (*padx*) or top and bottom
+         (*pady*) of the widget, as a screen distance or a pair of two
+         distances for the two sides (default ``0``).
+
+      *after*
+         Pack the widget after the given widget in the packing order, using the
+         same container.
+
+      *before*
+         Pack the widget before the given widget in the packing order, using
+         the same container.

+      The supported options are:
+
+      *x*, *y*
+         The absolute horizontal and vertical position of the widget's anchor
+         point, as a screen distance (default ``0``).
+
+      *relx*, *rely*
+         The horizontal and vertical position of the widget's anchor point as a
+         fraction of the container's width and height, where ``0.0`` is the
+         left or top edge and ``1.0`` is the right or bottom edge.
+         If both the absolute and the relative option are given, their values
+         are summed.
+
+      *anchor*
+         Which point of the widget is placed at the given position: an anchor

+
+      *width*, *height*
+         The absolute width and height of the widget, as a screen distance.
+         By default the widget's requested size is used.
+
+      *relwidth*, *relheight*
+         The width and height of the widget as a fraction of the container's
+         width and height.
+         If both the absolute and the relative option are given, their values
+         are summed.
+
+      *bordermode*
+         How the container's border affects placement: ``'inside'`` (the
+         default) measures the area inside the border, ``'outside'`` measures
+         the area including the border, and ``'ignore'`` uses the official X
+         area.
+
+      *in_*

+
+      *rowspan*, *columnspan*
+         The number of rows and columns the widget should span (default ``1``).
+
+      *sticky*
+         How to position or stretch the widget when its cell is larger than the
+         widget: a string containing zero or more of the characters ``'n'``,
+         ``'s'``, ``'e'`` and ``'w'``, naming the cell sides the widget sticks

+      between 0 and 1 giving the portion of the document that is currently
+      visible.
+      Otherwise the arguments are passed to the Tk ``yview`` widget command,
+      usually generated by a scrollbar; :meth:`yview_moveto` and
+      :meth:`yview_scroll` provide a more convenient interface.
+
+   .. method:: yview_moveto(fraction)
+
+      Adjust the view so that *fraction* of the total height of the document is
+      off-screen above the top.
+      *fraction* is a number between 0 and 1.
+
+   .. method:: yview_scroll(number, what)
+
+      Shift the view up or down by *number* units.
+      *what* is either ``'units'`` or ``'pages'``; a negative *number* scrolls
+      up and a positive one scrolls down.
+
+
+.. class:: BaseWidget(master, widgetName, cnf={}, kw={}, extra=())
+
+   Internal base class for all widgets.
+   It inherits from :class:`Misc` and adds the machinery that creates the
+   underlying Tk widget; application code normally uses :class:`Widget` or a
+   concrete widget class rather than instantiating :class:`!BaseWidget`
+   directly.
+
+   .. method:: destroy()
+
+      Destroy this widget and all of its children, removing the corresponding
+      Tk widgets and deleting the associated Tcl commands.
+
+
+.. class:: Widget(master, widgetName, cnf={}, kw={}, extra=())
+
+   Internal base class for the standard widgets.
+   It combines :class:`BaseWidget` with the geometry-manager mix-ins
+   :class:`Pack`, :class:`Place` and :class:`Grid`, so that every widget can be
+   managed by any of the three geometry managers.
+   The concrete widget classes (:class:`Button`, :class:`Label`, and so on)
+   derive from :class:`!Widget`.
+
+
+Toplevel widgets
+^^^^^^^^^^^^^^^^
+
+.. class:: Tk(screenName=None, baseName=None, className='Tk', useTk=True, sync=False, use=None)
+
+   Construct a toplevel Tk widget, which is usually the main window of an
+   application, and initialize a Tcl interpreter for this widget.  Each
+   instance has its own associated Tcl interpreter.
+   Inherits from :class:`Misc` and :class:`Wm`.
+
+   To create a Tcl interpreter without initializing the Tk subsystem, use the
+   :func:`Tcl` factory function instead.
+
+   The :class:`Tk` class is typically instantiated using all default values.
+   However, the following keyword arguments are currently recognized:
+
+   *screenName*
+      When given (as a string), sets the :envvar:`DISPLAY` environment
+      variable. (X11 only)
+   *baseName*
+      Name of the profile file.  By default, *baseName* is derived from the
+      program name (``sys.argv[0]``).
+   *className*
+      Name of the widget class.  Used as a profile file and also as the name
+      with which Tcl is invoked (*argv0* in *interp*).
+   *useTk*
+      If ``True``, initialize the Tk subsystem.  The :func:`tkinter.Tcl() <Tcl>`
+      function sets this to ``False``.
+   *sync*
+      If ``True``, execute all X server commands synchronously, so that errors
+      are reported immediately.  Can be used for debugging. (X11 only)
+   *use*
+      Specifies the *id* of the window in which to embed the application,
+      instead of it being created as an independent toplevel window. *id* must
+      be specified in the same way as the value for the -use option for
+      toplevel widgets (that is, it has a form like that returned by
+      :meth:`~Misc.winfo_id`).
+
+      Note that on some platforms this will only work correctly if *id* refers
+      to a Tk frame or toplevel that has its -container option enabled.
+
+   :class:`Tk` reads and interprets profile files, named
+   :file:`.{className}.tcl` and :file:`.{baseName}.tcl`, into the Tcl
+   interpreter and calls :func:`exec` on the contents of
+   :file:`.{className}.py` and :file:`.{baseName}.py`.  The path for the
+   profile files is the :envvar:`HOME` environment variable or, if that
+   isn't defined, then :data:`os.curdir`.
+
+   .. note::
+
+      On Windows, creating a Tcl interpreter (by instantiating :class:`Tk` or
+      calling :func:`Tcl`) sets the :envvar:`HOME` environment variable for
+      the process, if it is not already set, to ``%HOMEDRIVE%%HOMEPATH%`` (or
+      :envvar:`USERPROFILE`, or ``c:\``).  This is done by Tcl and can affect
+      other code that reads :envvar:`HOME`.
+
+   .. attribute:: tk
+
+      The Tk application object created by instantiating :class:`Tk`.  This
+      provides access to the Tcl interpreter.  Each widget that is attached
+      the same instance of :class:`Tk` has the same value for its :attr:`tk`
+      attribute.
+
+   .. attribute:: master
+
+      The widget object that contains this widget.
+      For :class:`Tk`, the :attr:`!master` is :const:`None` because it is the
+      main window.
+      The terms *master* and *parent* are similar and sometimes used
+      interchangeably as argument names; however, calling
+      :meth:`~Misc.winfo_parent` returns a string of the widget name whereas
+      :attr:`!master` returns the object.
+      *parent*/*child* reflects the tree-like relationship while *master* (or
+      *container*)/*content* reflects the container structure.
+
+   .. attribute:: children
+
+      The immediate descendants of this widget as a :class:`dict` with the
+      child widget names as the keys and the child instance objects as the
+      values.
+
+   .. method:: destroy()
+
+      Destroy this and all descendant widgets and, for the main window, end the
+      connection to the underlying Tcl interpreter.
+
+   .. method:: loadtk()
+
+      Finish loading and initializing the Tk subsystem.
+      This is needed only when the interpreter was created without Tk (for
+      example through :func:`Tcl`); it is called automatically when *useTk* is
+      true.
+
+   .. method:: readprofile(baseName, className)
+
+      Read and source the user's profile files :file:`.{className}.tcl` and
+      :file:`.{baseName}.tcl` into the Tcl interpreter, and execute the
+      corresponding :file:`.{className}.py` and :file:`.{baseName}.py` files.
+      This is called during initialization; see the description of the
+      constructor above.
+
+   .. method:: report_callback_exception(exc, val, tb)
+
+      Report a callback exception.
+      This is called when an exception propagates out of a Tkinter callback;
+      *exc*, *val* and *tb* are the exception type, value and traceback as
+      returned by :func:`sys.exc_info`.
+      The default implementation prints a traceback to :data:`sys.stderr`.
+      It can be overridden to customize error handling, for example to display
+      the traceback in a dialog.
+
+
+.. class:: Toplevel(master=None, cnf={}, **kw)
+
+   A :class:`!Toplevel` widget is a top-level window, similar to a
+   :class:`Frame` except that its X parent is the root window of a screen
+   rather than its logical parent.
+   Its primary purpose is to serve as a container for dialog boxes and other
+   collections of widgets; its only visible features are its background and an
+   optional 3-D border.
+   Notable options include *menu*, which installs a :class:`Menu` as the
+   window's menubar.
+   Inherits from :class:`BaseWidget` and :class:`Wm`, so a toplevel is managed
+   by the window manager.
+   Refer to the Tk ``toplevel`` manual page for the full list of options.
+
+
+Widget classes
+^^^^^^^^^^^^^^
+
+.. class:: Button(master=None, cnf={}, **kw)
+
+   A :class:`!Button` widget displays a textual string, bitmap or image and
+   invokes a command when the user presses it (by clicking mouse button 1 over
+   the button or, when the button has focus, by pressing the space key).
+   Inherits from :class:`Widget`.
+   In addition to the standard widget options, a button accepts the options
+   documented in the Tk ``button`` manual page, such as *command* (the callback
+   invoked when the button is pressed), *textvariable*, *state* and *default*.
+
+   .. method:: invoke()
+
+      Invoke the command associated with the button, if there is one, and
+      return its result, or an empty string if no command is associated with
+      the button.
+      This is ignored if the button's state is ``disabled``.
+
+   .. method:: flash()
+
+      Flash the button by redisplaying it several times, alternating between
+      the active and normal colors.
+      At the end of the flash the button is left in the same normal or active
+      state as when the method was called.
+      This is ignored if the button's state is ``disabled``.
+
+
+.. class:: Canvas(master=None, cnf={}, **kw)
+
+   A :class:`!Canvas` widget implements structured graphics.
+   It displays any number of *items*, such as arcs, lines, ovals, polygons,
+   rectangles, text, bitmaps, images and embedded windows, which may be drawn,
+   moved, re-colored and bound to events.
+   Inherits from :class:`Widget`, :class:`XView` and :class:`YView`, so the
+   view can be scrolled horizontally and vertically with :meth:`~XView.xview`
+   and :meth:`~YView.yview`.
+   Refer to the Tk ``canvas`` manual page for the full list of widget and item
+   options.
+
+   Each item has a unique integer *id*, assigned when it is created, and zero
+   or more string *tags*.
+   A tag is an arbitrary string that does not have the form of an integer; the
+   same tag may be shared by many items, which makes tags convenient for
+   grouping items.
+   The special tag ``'all'`` matches every item in the canvas, and
+   ``'current'`` matches the topmost item under the mouse pointer.
+   Most methods take a *tagOrId* argument that may be an integer id naming a
+   single item, or a tag naming zero or more items; as described in the Tk
+   ``canvas`` manual page, a tag may also be a logical expression of tags
+   combined with the operators ``&&``, ``||``, ``^``, ``!`` and parentheses.
+   When a method that operates on a single item is given a *tagOrId* matching
+   several items, it normally uses the lowest matching item in the display
+   list.
+
+   The items are kept in a *display list* that determines drawing order: items
+   later in the list are drawn on top of earlier ones.
+   A newly created item is placed at the top of the list; the order can be
+   changed with :meth:`tag_raise` and :meth:`tag_lower`.
+
+   .. method:: create_arc(*args, **kw)
+               create_bitmap(*args, **kw)
+               create_image(*args, **kw)
+               create_line(*args, **kw)
+               create_oval(*args, **kw)
+               create_polygon(*args, **kw)
+               create_rectangle(*args, **kw)
+               create_text(*args, **kw)
+               create_window(*args, **kw)
+
+      Create a new item of the corresponding type and return its integer id.
+      Each method is called as ``create_TYPE(coord..., **options)``: the
+      leading positional arguments give the coordinates that define the item
+      (as separate numbers, as a single sequence of numbers, or as coordinate
+      pairs), and the keyword arguments set item-specific options.
+      Coordinates and screen distances may be given as numbers (interpreted as
+      pixels) or as strings with a unit suffix (``'m'``, ``'c'``, ``'i'`` or
+      ``'p'`` for millimetres, centimetres, inches or printer's points), but
+      are always stored and returned in pixels.
+
+      The item types are: ``arc`` (an arc-shaped region that is a section of an
+      oval, defined by two diagonally opposite corners ``x1, y1, x2, y2`` of
+      the enclosing rectangle); ``bitmap`` (a two-color bitmap positioned at a
+      point ``x, y``); ``image`` (a Tk image positioned at a point ``x, y``);
+      ``line`` (a line or curve through the points ``x1, y1, ..., xn, yn``);
+      ``oval`` (a circle or ellipse inscribed in the rectangle
+      ``x1, y1, x2, y2``); ``polygon`` (a closed polygon through the points
+      ``x1, y1, ..., xn, yn``); ``rectangle`` (a rectangle with corners
+      ``x1, y1, x2, y2``); ``text`` (a string of text positioned at a point
+      ``x, y``); and ``window`` (a child widget embedded in the canvas at a
+      point ``x, y``, specified with the *window* option).
+
+      Most item types accept a common set of *standard item options*, plus a
+      few options specific to each type.
+      Option names are passed as keyword arguments, without the leading
+      hyphen.
+
+      The standard item options are:
+
+      *fill*
+         The color used to fill the item's interior, or to draw a *line*
+         item or the characters of a *text* item.
+         An empty string (the default for all types except *line* and *text*)
+         leaves the item unfilled.
+
+      *outline*
+         The color used to draw the item's outline.
+         An empty string draws no outline.
+
+      *width*
+         The width of the outline, defaulting to ``1.0``.
+         Has no effect if *outline* is empty.
+
+      *dash*
+         A dash pattern for the outline, given either as a sequence of
+         segment lengths in pixels or as a string of the characters
+         ``'.'``, ``','``, ``'-'``, ``'_'`` and space.
+         An empty pattern (the default) draws a solid outline.
+
+      *dashoffset*
+         The starting offset in pixels into the *dash* pattern.
+         Ignored if there is no *dash* pattern.
+
+      *stipple*
+         A bitmap used as a stipple pattern when filling the item.
+         Only well supported on X11.
+
+      *outlinestipple*
+         A bitmap used as a stipple pattern when drawing the outline.
+         Has no effect if *outline* is empty.
+
+      *offset*, *outlineoffset*
+         The offset of the fill and outline stipple patterns, given as
+         ``'x,y'`` or as a side such as ``'n'``, ``'se'`` or ``'center'``.
+         Stipple offsets are only supported on X11.
+
+      *state*
+         Overrides the canvas state for this item; one of ``'normal'``,
+         ``'disabled'`` or ``'hidden'``.
+
+      *tags*
+         A single tag or a sequence of tags to associate with the item,
+         replacing any existing tags.
+
+      Many of these options have *active...* and *disabled...* variants
+      (such as *activefill*, *disabledfill*, *activewidth*, *disableddash*,
+      *activeoutline*, *disabledstipple*) that override the base option when
+      the item is the active item (under the mouse pointer) or is in the
+      disabled state.
+
+      The following item types support additional options.
+
+      For ``arc`` items:
+
+      *start*
+         The start of the arc's angular range, in degrees measured
+         counter-clockwise from the 3-o'clock position.
+
+      *extent*
+         The size of the angular range, in degrees counter-clockwise from
+         *start*.
+
+      *style*
+         How the arc is drawn: ``'pieslice'`` (the default), ``'chord'`` or
+         ``'arc'``.
+
+      For ``line`` items:
+
+      *arrow*
+         Where to draw arrowheads: ``'none'`` (the default), ``'first'``,
+         ``'last'`` or ``'both'``.
+
+      *arrowshape*
+         A sequence of three distances describing the shape of the
+         arrowheads.
+
+      *capstyle*
+         How line ends are drawn: ``'butt'`` (the default), ``'projecting'``
+         or ``'round'``.
+
+      *joinstyle*
+         How line vertices are drawn: ``'round'`` (the default), ``'bevel'``
+         or ``'miter'``.
+
+      *smooth*
+         The smoothing method: a false value (the default) for no smoothing,
+         or ``'true'``/``'bezier'`` or ``'raw'`` to draw the line as a curve.
+
+      *splinesteps*
+         The number of line segments approximating each spline when
+         *smooth* is enabled.
+
+      For ``polygon`` items:
+
+      *joinstyle*, *smooth*, *splinesteps*
+         As for ``line`` items, applied to the polygon's outline.
+
+      For ``text`` items:
+
+      *text*
+         The string to display; newline characters start new lines.
+
+      *font*
+         The font used for the text.
+
+      *justify*
+         How lines are justified: ``'left'`` (the default), ``'right'`` or
+         ``'center'``.
+
+      *anchor*
+         How the text is positioned relative to its point, defaulting to
+         ``'center'``.
+
+      *width*
+         The maximum line length; if non-zero, lines are wrapped at spaces.
+
+      *angle*
+         How many degrees to rotate the text counter-clockwise about its
+         positioning point, from ``0.0`` to ``360.0`` (default ``0.0``).
+
+      *underline*
+         The index of a character to underline, or ``-1`` for none.
+
+      For ``bitmap`` items:
+
+      *bitmap*
+         The bitmap to display.
+
+      *anchor*
+         How the bitmap is positioned relative to its point.
+
+      *background*, *foreground*
+         The colors used for the bitmap's ``0`` and ``1`` pixels; an empty
+         *background* makes the ``0`` pixels transparent.
+         Both have *active...* and *disabled...* variants, and *bitmap* has
+         *activebitmap* and *disabledbitmap* variants.
+
+      For ``image`` items:
+
+      *image*
+         The Tk image to display, previously created with the image
+         protocols.
+
+      *anchor*
+         How the image is positioned relative to its point.
+
+      Both options have *active...* and *disabled...* variants
+      (*activeimage*, *disabledimage*) used in the active and disabled
+      states.
+
+      For ``window`` items:
+
+      *window*
+         The widget to embed; it must be a child of the canvas or of one of
+         its ancestors, and may not be a top-level window.
+
+      *anchor*
+         How the window is positioned relative to its point.
+
+      *width*, *height*
+         The size to assign to the window; if zero (the default), the window
+         is given its requested size.
+
+      ``oval`` and ``rectangle`` items have no type-specific options; they
+      use only the standard item options.
+
+      .. note::
+
+         Tk 8.6 added the *angle* option and Tk 9.0 added the *underline*
+         option for ``text`` items.
+
+   .. method:: coords(tagOrId)
+               coords(tagOrId, coordList, /)
+               coords(tagOrId, /, *coordList)
+
+      Query or modify the coordinates of an item.
+      With only *tagOrId*, return a list of the floating-point coordinates of
+      the item given by *tagOrId* (the first matching item if it matches
+      several).
+      Given new coordinates, replace the coordinates of that item with them;
+      like the ``create_*`` methods, the coordinates may be given as separate
+      numbers, as a single sequence, or as coordinate pairs.
+      The returned coordinates are always in pixels, regardless of the units
+      used to specify them; for rectangles, ovals and arcs they are ordered
+      left, top, right, bottom.
+
+      .. versionchanged:: 3.12
+         The arguments are now flattened: the coordinates may be given as
+         separate arguments, as a single sequence, or grouped in pairs, like
+         the ``create_*`` methods.
+
+
+   .. method:: move(tagOrId, xAmount, yAmount, /)
+
+      Move each of the items given by *tagOrId* in the canvas coordinate space
+      by adding *xAmount* to every x-coordinate and *yAmount* to every
+      y-coordinate of the item.
+
+   .. method:: moveto(tagOrId, x='', y='')
+
+      Move the items given by *tagOrId* so that the first coordinate pair (the
+      upper-left corner of the bounding box) of the lowest matching item is at
+      position (*x*, *y*).
+      *x* or *y* may be an empty string, in which case the corresponding
+      coordinate is unchanged.
+      All matching items keep their positions relative to each other.
+
+      .. versionadded:: 3.8
+
+
+   .. method:: scale(tagOrId, xOrigin, yOrigin, xScale, yScale, /)
+
+      Rescale the coordinates of all items given by *tagOrId* in canvas
+      coordinate space.
+      Each x-coordinate is adjusted so that its distance from *xOrigin* changes
+      by a factor of *xScale*, and each y-coordinate so that its distance from
+      *yOrigin* changes by a factor of *yScale* (a factor of ``1.0`` leaves the
+      coordinate unchanged).
+
+   .. method:: rotate(tagOrId, xOrigin, yOrigin, angle, /)
+
+      Rotate the coordinates of all items given by *tagOrId* in canvas
+      coordinate space about the origin (*xOrigin*, *yOrigin*) by *angle*
+      degrees anticlockwise.
+      Negative values of *angle* rotate clockwise.
+
+      .. versionadded:: next
+
+   .. method:: delete(*tagOrIds)
+
+      Delete each of the items given by the *tagOrIds* arguments.
+
+   .. method:: dchars(tagOrId, first, /)
+               dchars(tagOrId, first, last, /)
+
+      Delete from each of the items given by *tagOrId* the characters (for text
+      items) or coordinates (for line and polygon items) in the range from
+      *first* to *last* inclusive; *last* defaults to *first*.
+      Items that do not support indexing ignore this operation.
+
+   .. method:: insert(tagOrId, beforeThis, string, /)
+
+      Insert *string* into each of the items given by *tagOrId* just before the
+      character or coordinate whose index is *beforeThis*.
+      For line and polygon items *string* must be a valid sequence of
+      coordinates.
+
+   .. method:: rchars(tagOrId, first, last, string, /)
+
+      Replace the characters (for text items) or coordinates (for line and
+      polygon items) in the range from *first* to *last* inclusive of each of
+      the items given by *tagOrId* with *string*.
+      For line and polygon items *string* must be a valid sequence of
+      coordinates.
+      Items that do not support indexing ignore this operation.
+
+      .. versionadded:: next
+
+   .. method:: itemcget(tagOrId, option)
+
+      Return the current value of the configuration option *option* for the
+      item given by *tagOrId* (the lowest matching item if it matches several).
+      This is like :meth:`~Misc.cget` but applies to an individual item.
+
+   .. method:: itemconfig(tagOrId, cnf=None, **kw)
+      :no-typesetting:
+
+   .. method:: itemconfigure(tagOrId, cnf=None, **kw)
+
+      Query or modify the configuration options of the items given by
+      *tagOrId*.
+      This mirrors :meth:`~Misc.configure`, except that it applies to
+      individual items rather than to the canvas as a whole.
+      With no options, it returns a dictionary describing the current options
+      of the first matching item; otherwise it sets the given options on every
+      matching item.
+      The legal options are those accepted by the corresponding ``create_*``
+      method.
+      :meth:`itemconfig` is an alias of :meth:`!itemconfigure`.
+
+   .. method:: type(tagOrId)
+
+      Return the type of the item given by *tagOrId* (the first matching item
+      if it matches several), such as ``'rectangle'`` or ``'text'``, or
+      ``None`` if *tagOrId* does not match any item.
+
+   .. method:: gettags(tagOrId, /)
+
+      Return a tuple of the tags associated with the item given by *tagOrId*
+      (the first matching item in display-list order if it matches several).
+      Return an empty tuple if no item matches or the item has no tags.
+
+   .. method:: dtag(tagOrId, /)
+               dtag(tagOrId, tagToDelete, /)
+
+      Remove the tag *tagToDelete* (which defaults to *tagOrId*) from each of
+      the items given by *tagOrId*.
+      Items that do not have that tag are unaffected.
+
+   .. method:: addtag(newtag, searchSpec, /, *args)
+
+      Add the tag *newtag* to each item selected by the search specification
+      *searchSpec* (and any further *args*).
+      *searchSpec* is one of ``'above'``, ``'all'``, ``'below'``,
+      ``'closest'``, ``'enclosed'``, ``'overlapping'`` or ``'withtag'``; the
+      ``addtag_*`` methods below are convenient wrappers that supply each of
+      these forms.
+
+   .. method:: addtag_above(newtag, tagOrId)
+
+      Add the tag *newtag* to the item just above (after) *tagOrId* in the
+      display list.
+
+   .. method:: addtag_all(newtag)
+
+      Add the tag *newtag* to all items in the canvas.
+
+   .. method:: addtag_below(newtag, tagOrId)
+
+      Add the tag *newtag* to the item just below (before) *tagOrId* in the
+      display list.
+
+   .. method:: addtag_closest(newtag, x, y, halo=None, start=None)
+
+      Add the tag *newtag* to the item closest to the point (*x*, *y*).
+      If *halo* is given, any item within that distance of the point is treated
+      as overlapping it.
+      If *start* is given (a tag or id), select the topmost closest item that
+      lies below *start* in the display list, which can be used to step through
+      all the closest items.
+
+   .. method:: addtag_enclosed(newtag, x1, y1, x2, y2)
+
+      Add the tag *newtag* to every item completely enclosed within the
+      rectangle (*x1*, *y1*, *x2*, *y2*), where *x1* <= *x2* and *y1* <= *y2*.
+
+   .. method:: addtag_overlapping(newtag, x1, y1, x2, y2)
+
+      Add the tag *newtag* to every item that overlaps or is enclosed within
+      the rectangle (*x1*, *y1*, *x2*, *y2*), where *x1* <= *x2* and *y1* <=
+      *y2*.
+
+   .. method:: addtag_withtag(newtag, tagOrId)
+
+      Add the tag *newtag* to every item given by *tagOrId*.
+
+   .. method:: find(searchSpec, /, *args)
+
+      Return a tuple of the ids of all items selected by the search
+      specification *searchSpec* (and any further *args*), in stacking order
+      with the lowest item first.
+      The search specification has any of the forms accepted by :meth:`addtag`.
+      The ``find_*`` methods below are more convenient wrappers around it.
+
+   .. method:: find_above(tagOrId)
+
+      Return a tuple containing the id of the item just above *tagOrId* in the
+      display list.
+
+   .. method:: find_all()
+
+      Return a tuple of the ids of all items in the canvas, in stacking order.
+
+   .. method:: find_below(tagOrId)
+
+      Return a tuple containing the id of the item just below *tagOrId* in the
+      display list.
+
+   .. method:: find_closest(x, y, halo=None, start=None)
+
+      Return a tuple containing the id of the item closest to the point (*x*,
+      *y*).
+      *halo* and *start* are interpreted as for :meth:`addtag_closest`.
+
+   .. method:: find_enclosed(x1, y1, x2, y2)
+
+      Return a tuple of the ids of all items completely enclosed within the
+      rectangle (*x1*, *y1*, *x2*, *y2*).
+
+   .. method:: find_overlapping(x1, y1, x2, y2)
+
+      Return a tuple of the ids of all items that overlap or are enclosed
+      within the rectangle (*x1*, *y1*, *x2*, *y2*).
+
+   .. method:: find_withtag(tagOrId)
+

+   .. method:: tkraise(tagOrId, aboveThis=None, /)
+      :no-typesetting:
+

+
+      Move all items given by *tagOrId* to a new position in the display list
+      just above the item given by *aboveThis*, or to the top of the display
+      list if *aboveThis* is omitted.
+      When several items are moved their relative order is preserved.
+      This has no effect on embedded window items, whose stacking order is
+      controlled by :meth:`Misc.tkraise` and :meth:`Misc.lower` instead.
+      :meth:`lift` and :meth:`tkraise` are aliases of :meth:`!tag_raise`.
+
+   .. method:: lower(tagOrId, belowThis=None, /)
+      :no-typesetting:
+
+   .. method:: tag_lower(tagOrId, belowThis=None, /)
+
+      Move all items given by *tagOrId* to a new position in the display list
+      just below the item given by *belowThis*, or to the bottom of the display
+      list if *belowThis* is omitted.
+      When several items are moved their relative order is preserved.
+      This has no effect on embedded window items.
+      :meth:`lower` is an alias of :meth:`!tag_lower`.
+
+      .. note::
+
+         On a :class:`Canvas`, :meth:`tkraise`/:meth:`lift` and :meth:`lower`
+         restack canvas items,
+         shadowing the inherited :meth:`Misc.tkraise`/:meth:`Misc.lift` and
+         :meth:`Misc.lower` methods that restack the widget itself,
+         which are therefore not available.
+
+   .. method:: tag_bind(tagOrId, sequence=None, func=None, add=None)
+
+      Bind the callback *func* to the event *sequence* for all items given by
+      *tagOrId*, so that *func* is invoked whenever that event occurs for one
+      of the items.
+      This is like :meth:`Widget.bind <Misc.bind>` but operates on canvas items
+      rather than on whole widgets; only mouse, keyboard and virtual events may
+      be bound.
+      Mouse events are directed to the current item and keyboard events to the
+      focus item (see :meth:`focus`).
+      If *add* is true the new binding is added to any existing bindings for
+      the same sequence, rather than replacing them.
+      Return the identifier of the bound function, which can be passed to
+      :meth:`tag_unbind`.
+
+   .. method:: tag_unbind(tagOrId, sequence, funcid=None)
+
+      Remove for all items given by *tagOrId* the binding for the event
+      *sequence*.
+      If *funcid* is given, only that callback (as returned by
+      :meth:`tag_bind`) is unbound and deregistered.
+
+      .. versionchanged:: 3.13
+         If *funcid* is given, only that callback is unbound.
+
+
+   .. method:: bbox(tagOrId, /, *tagOrIds)
+
+      Return a 4-tuple ``(x1, y1, x2, y2)`` giving an approximate bounding box,
+      in pixels, that encloses all the items given by *tagOrId* and any further
+      *tagOrIds*.
+      The result may overestimate the true bounding box by a few pixels.
+      Return ``None`` if no item matches or the matching items have nothing to
+      display.
+
+      This shadows the inherited :meth:`!Misc.bbox`;
+      use :meth:`~Misc.grid_bbox` for the grid bounding box.
+
+   .. method:: canvasx(screenx, gridspacing=None)
+
+      Given a window x-coordinate *screenx*, return the canvas x-coordinate
+      displayed at that location.
+      If *gridspacing* is given, the result is rounded to the nearest multiple
+      of *gridspacing* units.
+
+   .. method:: canvasy(screeny, gridspacing=None)
+
+      Given a window y-coordinate *screeny*, return the canvas y-coordinate
+      displayed at that location.
+      If *gridspacing* is given, the result is rounded to the nearest multiple
+      of *gridspacing* units.
+
+   .. method:: focus()
+               focus(tagOrId, /)
+
+      With *tagOrId*, set the keyboard focus for the canvas to the first item
+      given by *tagOrId* that supports the insertion cursor; the focus is left
+      unchanged if no such item exists.
+      If *tagOrId* is an empty string, reset the focus so that no item has it.
+      With no argument, return the id of the item that currently has the focus,
+      or an empty string if none does.
+      An item only displays the insertion cursor when both it is the focus item
+      and its canvas has the input focus.
+
+      This shadows the inherited :meth:`!Misc.focus`;
+      use :meth:`~Misc.focus_set` to focus the widget itself.
+
+   .. method:: icursor(tagOrId, index, /)
+
+      Set the insertion cursor of the items given by *tagOrId* to just before
+      the character given by *index*.
+      Items that do not support an insertion cursor are unaffected.
+      The cursor is only displayed when the item has the focus, but its
+      position may be set at any time.
+
+   .. method:: index(tagOrId, index, /)
+
+      Return as an integer the numerical index within *tagOrId* corresponding
+      to *index*, which is a textual description of a position (for text items
+      an index into the characters, for line and polygon items an index into
+      the coordinates).
+      If *tagOrId* matches several items, the first one that supports indexing
+      is used.
+
+   .. method:: select_adjust(tagOrId, index)
+
+      Adjust the end of the selection in *tagOrId* nearest to *index* so that
+      it is at *index*, and make the other end the anchor point for future
+      :meth:`select_to` calls.
+      If the selection is not currently in *tagOrId*, this behaves like
+      :meth:`select_to`.
+
+   .. method:: select_clear()
+
+      Clear the selection if it is in this canvas; otherwise do nothing.
+
+   .. method:: select_from(tagOrId, index)
+
+      Set the selection anchor point to just before the character given by
+      *index* in the item given by *tagOrId*.
+      This does not change the selection itself; it sets the fixed end for
+      future :meth:`select_to` calls.
+
+   .. method:: select_item()
+
+      Return the id of the item that holds the selection, or ``None`` if the
+      selection is not in this canvas.
+      Unlike :meth:`find` and the ``find_*`` methods, this returns the id as a
+      string rather than an integer.
+
+   .. method:: select_to(tagOrId, index)
+
+      Set the selection to the characters of *tagOrId* between the selection
+      anchor point and *index*, inclusive of *index*.
+      The anchor point is the one set by the most recent :meth:`select_adjust`
+      or :meth:`select_from` call.
+
+   .. method:: scan_mark(x, y)
+
+      Record *x*, *y* and the current view, for use with later
+      :meth:`scan_dragto` calls.
+      This is typically bound to a mouse button press in the widget.
+
+   .. method:: scan_dragto(x, y, gain=10)
+
+      Scroll the canvas by *gain* times the difference between *x*, *y* and the
+      coordinates passed to the last :meth:`scan_mark` call.
+      This is typically bound to mouse motion events in the widget, producing
+      the effect of dragging the canvas at high speed through its window.
+
+   .. method:: postscript(cnf={}, **kw)
+
+      Generate a PostScript (Encapsulated PostScript, version 3.0)
+      representation of part or all of the canvas.
+      If the *file* or *channel* option is given, the PostScript is written
+      there and an empty string is returned; otherwise it is returned as a
+      string.
+      By default only the area currently visible in the window is generated, so
+      it is usually necessary either to call :meth:`~Misc.update` first or to
+      use the *width* and *height* options.
+      Supported options include *colormap*, *colormode*, *file*, *fontmap*,
+      *height*, *pageanchor*, *pageheight*, *pagewidth*, *pagex*, *pagey*,
+      *rotate*, *width*, *x* and *y*.
+
+
+.. class:: Checkbutton(master=None, cnf={}, **kw)
+
+   A :class:`!Checkbutton` widget displays a textual string, bitmap or image
+   together with a square indicator, and toggles a boolean selection when
+   pressed.
+   It has all the behavior of a simple button and, in addition, can be
+   selected: when selected the indicator is drawn with a check mark and the
+   associated variable is set to the ``onvalue``, and when deselected the
+   indicator is drawn empty and the variable is set to the ``offvalue``.
+   Inherits from :class:`Widget`.
+   In addition to the standard widget options, a checkbutton accepts the
+   options documented in the Tk ``checkbutton`` manual page, such as
+   *variable*, *onvalue*, *offvalue* and *command*.
+
+   .. method:: invoke()
+
+      Do just what would happen if the user pressed the checkbutton with the
+      mouse: toggle the selection state of the button and invoke the associated
+      command, if there is one.
+      Return the result of the command, or an empty string if no command is
+      associated with the checkbutton.
+      This is ignored if the checkbutton's state is ``disabled``.
+
+   .. method:: select()
+
+      Select the checkbutton and set the associated variable to its
+      ``onvalue``.
+
+   .. method:: deselect()
+
+      Deselect the checkbutton and set the associated variable to its
+      ``offvalue``.
+
+   .. method:: toggle()
+
+      Toggle the selection state of the button, redisplaying it and modifying
+      its associated variable to reflect the new state.
+
+   .. method:: flash()
+
+      Flash the checkbutton by redisplaying it several times, alternating
+      between the active and normal colors.
+      At the end of the flash the checkbutton is left in the same normal or
+      active state as when the method was called.
+      This is ignored if the checkbutton's state is ``disabled``.
+
+
+.. class:: Entry(master=None, cnf={}, **kw)
+
+   An :class:`!Entry` widget displays a single line of text and lets the user
+   edit it.
+   Inherits from :class:`Widget` and :class:`XView`; since entries can hold
+   strings too long to fit in the window, they support horizontal scrolling
+   through :meth:`~XView.xview`.
+
+   In addition to the standard widget options, an entry accepts the options
+   documented in the Tk ``entry`` manual page.
+   Notable ones are *textvariable* (the name of a variable kept in sync with
+   the entry's contents), *show* (if set, each character is displayed as the
+   given character rather than its true value, useful for password entry),
+   *validate* and *validatecommand* (which together let a callback accept or
+   reject edits), and *state* (one of ``'normal'``, ``'disabled'`` or
+   ``'readonly'``).
+
+   Many of the methods below take an *index* argument that selects a character
+   in the entry's string.
+   As described in the Tk ``entry`` manual page, *index* may be a number
+   (counting from 0), ``'insert'`` (the character just after the insertion
+   cursor), ``'end'`` (just after the last character), ``'anchor'`` (the
+   selection anchor point), ``'sel.first'`` and ``'sel.last'`` (the ends of the
+   selection), or ``@x`` (the character covering pixel x-coordinate *x* in the
+   window).
+   Out-of-range indices are rounded to the nearest legal value.
+
+   .. method:: delete(first, last=None)
+
+      Delete the characters from index *first* up to but not including index
+      *last*.
+      If *last* is omitted, only the single character at *first* is deleted.
+
+   .. method:: get()
+
+      Return the entry's current string.
+
+   .. method:: insert(index, string)
+
+      Insert *string* just before the character given by *index*.
+
+   .. method:: icursor(index)
+
+      Arrange for the insertion cursor to be displayed just before the
+      character given by *index*.
+
+   .. method:: index(index)
+
+      Return the numerical index corresponding to *index*.
+
+   .. method:: select_adjust(index)
+      :no-typesetting:
+
+   .. method:: selection_adjust(index)
+
+      Locate the end of the selection nearest to the character given by
+      *index*, and adjust that end to be at *index* (including but not going
+      beyond it); the other end becomes the anchor point for future
+      :meth:`selection_to` calls.
+      If there is no selection in the entry, a new one is created between
+      *index* and the most recent anchor point, inclusive.
+      :meth:`select_adjust` is an alias of :meth:`!selection_adjust`.
+
+   .. method:: select_clear()
+      :no-typesetting:
+
+   .. method:: selection_clear()
+
+      Clear the selection if it is currently in this widget.
+      If the selection is not in this widget the method has no effect.
+      :meth:`select_clear` is an alias of :meth:`!selection_clear`.
+
+      .. note::
+
+         This shadows the inherited :meth:`Misc.selection_clear`,
+         which clears the X selection;
+         that method is not available on an :class:`Entry`.
+
+   .. method:: select_from(index)
+      :no-typesetting:
+
+   .. method:: selection_from(index)
+
+      Set the selection anchor point to just before the character given by
+      *index*, without changing the selection.
+      :meth:`select_from` is an alias of :meth:`!selection_from`.
+
+   .. method:: select_present()
+      :no-typesetting:
+
+   .. method:: selection_present()
+
+      Return ``True`` if there are characters selected in the entry, ``False``
+      otherwise.
+      :meth:`select_present` is an alias of :meth:`!selection_present`.
+
+   .. method:: select_range(start, end)
+      :no-typesetting:
+
+   .. method:: selection_range(start, end)
+
+      Set the selection to include the characters starting with the one indexed
+      by *start* and ending with the one just before *end*.
+      If *end* refers to the same character as *start* or an earlier one, the
+      selection is cleared.
+      :meth:`select_range` is an alias of :meth:`!selection_range`.
+
+   .. method:: select_to(index)
+      :no-typesetting:
+
+   .. method:: selection_to(index)
+
+      Set the selection between the anchor point and *index*: if *index* is
+      before the anchor point, the selection runs from *index* up to but not
+      including the anchor; if *index* is after it, from the anchor up to but
+      not including *index*; if they coincide, nothing happens.
+      The anchor point is the one set by the most recent :meth:`selection_from`
+      or :meth:`selection_adjust` call.
+      If there is no selection in the entry, a new one is created using the
+      most recent anchor point.
+      :meth:`select_to` is an alias of :meth:`!selection_to`.
+
+   .. method:: scan_mark(x)
+
+      Record *x* and the current view in the entry window, for use with later
+      :meth:`scan_dragto` calls.
+      Typically associated with a mouse button press in the widget.
+
+   .. method:: scan_dragto(x)
+
+      Compute the difference between *x* and the *x* given to the last
+      :meth:`scan_mark` call, and adjust the view left or right by 10 times
+      that difference.
+      Typically associated with mouse motion events, to produce the effect of
+      dragging the entry at high speed through the window.
+
+   .. method:: validate()
+
+      Force an evaluation of the command given by the *validatecommand* option,
+      independently of the conditions specified by the *validate* option, and
+      return whether the value is considered valid.
+
+      .. versionadded:: next

+
+.. class:: Frame(master=None, cnf={}, **kw)
+
+   A :class:`!Frame` widget is a simple container.
+   Its primary purpose is to act as a spacer or container for complex window
+   layouts; its only features are its background and an optional 3-D border to
+   make the frame appear raised or sunken.
+   Inherits from :class:`Widget`.
+   Refer to the Tk ``frame`` manual page for the full list of options.
+
+
+.. class:: Label(master=None, cnf={}, **kw)
+
+   A :class:`!Label` widget displays a non-interactive textual string, bitmap
+   or image.
+   The displayed text is set with the *text* option or linked to a variable
+   through *textvariable*, and an image can be shown using the *image* option.
+   Text must all be in a single font but may occupy multiple lines, and one
+   character may be underlined with the *underline* option.
+   Inherits from :class:`Widget`.
+   Refer to the Tk ``label`` manual page for the full list of options.
+
+
+.. class:: LabelFrame(master=None, cnf={}, **kw)
+
+   A :class:`!LabelFrame` widget is a container that has the features of a
+   :class:`Frame` plus the ability to display a label.
+   The label text is set with the *text* option and positioned with
+   *labelanchor*, or an arbitrary widget may be used as the label by giving it
+   as the *labelwidget* option.
+   Inherits from :class:`Widget`.
+   Refer to the Tk ``labelframe`` manual page for the full list of options.
+
+
+.. class:: Listbox(master=None, cnf={}, **kw)
+
+   A :class:`!Listbox` widget displays a list of single-line text items, one
+   per line, of which the user can select one or more.
+   The way the selection behaves is governed by the *selectmode* option, which
+   is one of ``browse`` (the default; at most one item, which may be dragged
+   with the mouse), ``single`` (at most one item), ``multiple`` (any number of
+   items, toggled individually), or ``extended`` (any number of items,
+   including discontiguous ranges, selected by clicking and dragging).
+   Inherits from :class:`Widget`, :class:`XView` and :class:`YView`, so the
+   view can be scrolled horizontally and vertically with :meth:`~XView.xview`
+   and :meth:`~YView.yview`.
+   Refer to the Tk ``listbox`` manual page for the full list of options.
+
+   Many of the methods take an *index* argument identifying a particular item.
+   As described in the Tk ``listbox`` manual page, *index* may be a numeric
+   index (counting from 0 at the top), ``'active'`` (the item with the location
+   cursor, set with :meth:`activate`), ``'anchor'`` (the selection anchor, set
+   with :meth:`selection_anchor`), ``'end'`` (the last item, or for
+   :meth:`index` and :meth:`insert` the position just after it), or ``@x,y``
+   (the item covering pixel coordinates *x*, *y* in the listbox window).
+   Arguments named *first* and *last* are indices of the same forms.
+
+   .. method:: insert(index, *elements)
+
+      Insert the given *elements* as new items just before the item given by
+      *index*.
+      If *index* is ``'end'``, the new items are appended to the end of the
+      list.
+
+   .. method:: delete(first, last=None)
+
+      Delete the items in the range from *first* to *last* inclusive.
+      If *last* is omitted, it defaults to *first*, so that a single item is
+      deleted.
+
+   .. method:: get(first, last=None)
+
+      If *last* is omitted, return the contents of the item given by *first*,
+      or an empty string if *first* refers to a non-existent item.
+      If *last* is given, return a tuple of all the items in the range from
+      *first* to *last* inclusive.
+
+   .. method:: size()
+
+      Return the total number of items in the listbox.
+
+      This shadows the inherited :meth:`!Misc.size`;
+      use :meth:`~Misc.grid_size` for the grid size.
+
+   .. method:: index(index)
+
+      Return the integer index value corresponding to *index*, or ``None`` if
+      *index* is out of range.
+      If *index* is ``'end'``, the result is a count of the number of items in
+      the listbox (not the index of the last item).
+
+   .. method:: bbox(index)
+
+      Return a tuple ``(x, y, width, height)`` describing the bounding box, in
+      pixels relative to the widget, of the text of the item given by *index*.
+      Return ``None`` if no part of that item is visible on the screen, or if
+      *index* refers to a non-existent item; if the item is only partly
+      visible, the result still gives the full area of the item, including the
+      parts that are not visible.
+
+      This shadows the inherited :meth:`!Misc.bbox`;
+      use :meth:`~Misc.grid_bbox` for the grid bounding box.
+
+   .. method:: nearest(y)
+
+      Given a y-coordinate within the listbox window, return the index of the
+      visible item nearest to that y-coordinate.
+
+   .. method:: see(index)
+
+      Adjust the view so that the item given by *index* is visible.
+      If the item is already visible the method has no effect; if it is near an
+      edge of the window the listbox scrolls just enough to bring it into view
+      at that edge, otherwise the listbox scrolls to center the item.
+
+   .. method:: activate(index)
+
+      Set the active item to the one given by *index*.
+      If *index* is outside the range of items, the closest item is activated
+      instead.
+      The active item is drawn as specified by the *activestyle* option when
+      the widget has the input focus, and its index may be retrieved with the
+      ``'active'`` index.
+
+   .. method:: curselection()
+
+      Return a tuple containing the numerical indices of all of the items that
+      are currently selected, or an empty tuple if no items are selected.
+
+   .. method:: select_anchor(index)
+      :no-typesetting:
+
+   .. method:: selection_anchor(index)
+
+      Set the selection anchor to the item given by *index*.
+      If *index* refers to a non-existent item, the closest item is used.
+      The selection anchor is the end of the selection that is fixed while
+      dragging out a selection with the mouse, and may afterwards be referred
+      to with the ``'anchor'`` index.
+      :meth:`select_anchor` is an alias of :meth:`!selection_anchor`.
+
+   .. method:: select_clear(first, last=None)
+      :no-typesetting:
+
+   .. method:: selection_clear(first, last=None)
+
+      Deselect any of the items in the range from *first* to *last* inclusive
+      that are selected.
+      The selection state of items outside this range is not changed.
+      :meth:`select_clear` is an alias of :meth:`!selection_clear`.
+
+      .. note::
+
+         This shadows the inherited :meth:`Misc.selection_clear`,
+         which clears the X selection;
+         that method is not available on a :class:`Listbox`.
+
+   .. method:: select_includes(index)
+      :no-typesetting:
+
+   .. method:: selection_includes(index)
+
+      Return ``True`` if the item given by *index* is currently selected,
+      ``False`` otherwise.
+      :meth:`select_includes` is an alias of :meth:`!selection_includes`.
+
+   .. method:: select_set(first, last=None)
+      :no-typesetting:
+
+   .. method:: selection_set(first, last=None)
+
+      Select all of the items in the range from *first* to *last* inclusive,
+      without affecting the selection state of items outside that range.
+      :meth:`select_set` is an alias of :meth:`!selection_set`.
+
+   .. method:: itemcget(index, option)
+
+      Return the current value of the configuration option *option* for the
+      item given by *index*.
+
+   .. method:: itemconfig(index, cnf=None, **kw)
+      :no-typesetting:
+
+   .. method:: itemconfigure(index, cnf=None, **kw)
+
+      Query or modify the configuration options of the item given by *index*.
+      This mirrors :meth:`~Misc.configure`, except that it applies to an
+      individual item rather than to the listbox as a whole.
+      With no options, it returns a dictionary describing the current options
+      of the item; otherwise it sets the given options.
+      The supported item options are *background*, *foreground*,
+      *selectbackground* and *selectforeground*.
+      :meth:`itemconfig` is an alias of :meth:`!itemconfigure`.
+
+   .. method:: scan_mark(x, y)
+
+      Record *x*, *y* and the current view, for use with later
+      :meth:`scan_dragto` calls.
+      This is typically bound to a mouse button press in the widget.
+
+   .. method:: scan_dragto(x, y)
+
+      Scroll the listbox by 10 times the difference between *x*, *y* and the
+      coordinates passed to the last :meth:`scan_mark` call.
+      This is typically bound to mouse motion events in the widget, producing
+      the effect of dragging the list at high speed through the window.
+
+
+.. class:: Menu(master=None, cnf={}, **kw)
+
+   A :class:`!Menu` widget displays a column of entries, each of which may be a
+   command, a checkbutton, a radiobutton, a cascade (which posts an associated
+   submenu) or a separator.
+   Menus are used as the menubar of a toplevel window, as pulldown menus posted
+   from a cascade entry or menubutton, and as popup menus.
+   Inherits from :class:`Widget`.
+
+   Many of the entry methods take an *index* argument that selects which entry
+   to operate on.
+   As described in the Tk ``menu`` manual page, *index* may be a numeric index
+   (counting from 0 at the top), ``'active'`` (the currently active entry),
+   ``'end'`` or ``'last'`` (the bottommost entry), ``'none'`` (no entry at all,
+   written ``{}`` in Tcl), ``@y`` (the entry covering pixel y-coordinate *y* in
+   the menu window), or a pattern matched against the labels of the entries
+   from the top down.
+
+   .. method:: add(itemType, cnf={}, **kw)
+
+      Add a new entry to the bottom of the menu.
+      *itemType* is one of ``'command'``, ``'cascade'``, ``'checkbutton'``,
+      ``'radiobutton'`` or ``'separator'`` and determines the type of the new
+      entry; the remaining options configure it.
+      The :meth:`!add_command`, :meth:`!add_cascade`, :meth:`!add_checkbutton`,
+      :meth:`!add_radiobutton` and :meth:`!add_separator` convenience methods
+      call this method with the corresponding *itemType*.
+
+      The entry is configured by the following options, although not every
+      option applies to every entry type (a separator accepts none of them):
+
+      *label*
+         The text to display in the entry.
+
+      *command*
+         The function to call when the entry is invoked (command, checkbutton
+         and radiobutton entries).
+
+      *accelerator*
+         A string displayed at the right of the entry to advertise an
+         accelerator keystroke; it does not itself create the binding.
+
+      *underline*
+         The index of a character in the label to underline for keyboard
+         traversal.
+
+      *state*
+         One of ``'normal'``, ``'active'`` or ``'disabled'``.
+
+      *image*
+         An image to display instead of, or together with, the text label.
+
+      *compound*
+         Where to show the image relative to the text: ``'none'`` (the
+         default), ``'text'``, ``'image'``, ``'top'``, ``'bottom'``, ``'left'``
+         or ``'right'``.
+
+      *bitmap*
+         A bitmap to display instead of the text label.
+
+      *font*
+         The font to use for the text.
+
+      *background*, *foreground*
+         The entry's background and foreground colors in its normal state
+         (ignored on macOS).
+
+      *activebackground*, *activeforeground*
+         The background and foreground colors used when the entry is active
+         (ignored on macOS).
+
+      *columnbreak*
+         If true, the entry starts a new column instead of being placed below
+         the previous entry.
+
+      *hidemargin*
+         If true, the standard margin around the entry is omitted, which is
+         useful when a menu is used as a palette.
+
+      *menu*
+         The submenu posted by a cascade entry; it must be a child of this
+         menu.
+
+      *variable*
+         The variable associated with a checkbutton or radiobutton entry.
+
+      *onvalue*, *offvalue*
+         The values stored in *variable* when a checkbutton entry is selected
+         or cleared.
+
+      *value*
+         The value stored in *variable* when a radiobutton entry is selected.
+
+      *indicatoron*
+         Whether to display the indicator of a checkbutton or radiobutton
+         entry.
+
+      *selectcolor*
+         The color of the indicator of a checkbutton or radiobutton entry when
+         it is selected.
+
+      *selectimage*
+         The image displayed when a checkbutton or radiobutton entry is
+         selected and *image* is also given.
+
+   .. method:: add_cascade(cnf={}, **kw)
+
+      Add a new cascade entry to the bottom of the menu.
+      A cascade entry has an associated submenu, given by its *menu* option,
+      which must be a child of this menu; posting the entry posts the submenu
+      next to it.
+
+   .. method:: add_checkbutton(cnf={}, **kw)
+
+      Add a new checkbutton entry to the bottom of the menu.
+      When invoked, a checkbutton entry toggles between its *onvalue* and
+      *offvalue*, storing the result in its associated *variable*, and displays
+      an indicator showing whether it is selected.
+
+   .. method:: add_command(cnf={}, **kw)
+
+      Add a new command entry to the bottom of the menu.
+      A command entry behaves much like a button: when it is invoked, the
+      callback given by its *command* option is called.
+
+   .. method:: add_radiobutton(cnf={}, **kw)
+
+      Add a new radiobutton entry to the bottom of the menu.
+      Radiobutton entries sharing the same *variable* form a group of which
+      only one may be selected at a time; selecting an entry stores its *value*
+      in the variable.
+
+   .. method:: add_separator(cnf={}, **kw)
+
+      Add a separator to the bottom of the menu.
+      A separator is displayed as a horizontal dividing line and cannot be
+      activated or invoked.
+
+   .. method:: insert(index, itemType, cnf={}, **kw)
+
+      Same as :meth:`add`, except that the new entry is inserted just before
+      the entry given by *index* instead of being appended to the end of the
+      menu.
+      *itemType* is one of ``'command'``, ``'cascade'``, ``'checkbutton'``,
+      ``'radiobutton'`` or ``'separator'``.
+      The :meth:`!insert_command`, :meth:`!insert_cascade`,
+      :meth:`!insert_checkbutton`, :meth:`!insert_radiobutton` and
+      :meth:`!insert_separator` convenience methods call this method with the
+      corresponding *itemType*.
+
+   .. method:: insert_cascade(index, cnf={}, **kw)
+
+      Insert a new cascade entry before the entry given by *index* (see
+      :meth:`add_cascade`).
+
+   .. method:: insert_checkbutton(index, cnf={}, **kw)
+
+      Insert a new checkbutton entry before the entry given by *index* (see
+      :meth:`add_checkbutton`).
+
+   .. method:: insert_command(index, cnf={}, **kw)
+
+      Insert a new command entry before the entry given by *index* (see
+      :meth:`add_command`).
+
+   .. method:: insert_radiobutton(index, cnf={}, **kw)
+
+      Insert a new radiobutton entry before the entry given by *index* (see
+      :meth:`add_radiobutton`).
+
+   .. method:: insert_separator(index, cnf={}, **kw)
+
+      Insert a separator before the entry given by *index* (see
+      :meth:`add_separator`).
+
+   .. method:: delete(index1, index2=None)
+
+      Delete all of the menu entries between *index1* and *index2* inclusive.
+      If *index2* is omitted, it defaults to *index1*, so that a single entry
+      is deleted.
+      Attempts to delete a tear-off entry are ignored; remove it by changing
+      the *tearoff* option instead.
+
+   .. method:: entrycget(index, option)
+
+      Return the current value of the configuration option *option* for the
+      entry given by *index*.
+
+   .. method:: entryconfig(index, cnf=None, **kw)
+      :no-typesetting:
+
+   .. method:: entryconfigure(index, cnf=None, **kw)
+
+      Query or modify the configuration options of the entry given by *index*.
+      This mirrors :meth:`~Misc.configure`, except that it applies to an
+      individual entry rather than to the menu as a whole.
+      With no options, it returns a dictionary describing the current options
+      of the entry; otherwise it sets the given options.
+      The supported options are those accepted by :meth:`add` for the entry's
+      type.
+      :meth:`entryconfig` is an alias of :meth:`!entryconfigure`.
+
+   .. method:: index(index)
+
+      Return the numerical index corresponding to *index*, or ``None`` if
+      *index* selects no entry.
+
+   .. method:: type(index)
+
+      Return the type of the entry given by *index*: one of ``'command'``,
+      ``'cascade'``, ``'checkbutton'``, ``'radiobutton'``, ``'separator'`` or
+      ``'tearoff'`` (for the tear-off entry).
+
+   .. method:: activate(index)
+
+      Make the entry given by *index* the active entry, redisplaying it with
+      its active colors, and deactivate any previously active entry.
+      If *index* selects no entry, or the selected entry is disabled, the menu
+      ends up with no active entry.
+
+   .. method:: invoke(index)
+
+      Invoke the action of the entry given by *index*, as if it had been
+      clicked.
+      Nothing happens if the entry is disabled.
+      If the entry has a *command* associated with it, the result of that
+      command is returned; otherwise the result is an empty string.
+
+   .. method:: post(x, y)
+
+      Display the menu on the screen at the root-window coordinates *x* and
+      *y*, adjusting them if necessary so that the whole menu is visible.
+      If the *postcommand* option has been specified, it is evaluated before
+      the menu is posted.
+
+   .. method:: postcascade(index)
+
+      Post the submenu associated with the cascade entry given by *index*,
+      unposting any previously posted submenu.
+      This has no effect if *index* does not name a cascade entry or if the
+      menu itself is not posted.
+
+      .. versionadded:: next
+
+   .. method:: tk_popup(x, y, entry='')
+
+      Post the menu as a popup at the root-window coordinates *x* and *y*.
+      If *entry* is given, the menu is positioned so that this entry is
+      displayed under the pointer.
+
+   .. method:: unpost()
+
+      Unmap the menu so that it is no longer displayed, also unposting any
+      posted lower-level cascaded submenu.
+      This has no effect on Windows and macOS, which manage the unposting of
+      menus themselves.
+
+   .. method:: xposition(index)
+
+      Return the x-coordinate, within the menu window, of the leftmost pixel of
+      the entry given by *index*.
+
+      .. versionadded:: 3.3
+
+   .. method:: yposition(index)
+
+      Return the y-coordinate, within the menu window, of the topmost pixel of
+      the entry given by *index*.
+
+
+.. class:: Menubutton(master=None, cnf={}, **kw)
+
+   A :class:`!Menubutton` widget displays a textual string, bitmap or image and
+   posts an associated :class:`Menu`, given by its *menu* option, when the user
+   presses it.
+   Like a :class:`Label` it can show *text*, a *textvariable*, or an *image*,
+   and the *direction* option controls where the menu appears relative to the
+   button.
+   Inherits from :class:`Widget`.
+   Refer to the Tk ``menubutton`` manual page for the full list of options.
+
+
+.. class:: Message(master=None, cnf={}, **kw)
+
+   A :class:`!Message` widget displays a non-interactive textual string, given
+   by the *text* option or linked to a variable through *textvariable*.
+   Unlike a :class:`Label`, it breaks the string into multiple lines in order
+   to produce a given aspect ratio, choosing line breaks at word boundaries,
+   and it can justify the text left, centered or right.
+   Inherits from :class:`Widget`.
+   Refer to the Tk ``message`` manual page for the full list of options.
+
+
+.. class:: OptionMenu(master, variable, value, *values, **kwargs)
+
+   A helper subclass of :class:`Menubutton` that displays a pop-up menu of
+   mutually exclusive choices.
+   *variable* is a :class:`Variable` kept in sync with the selection, *value*
+   is the initial choice, and *values* are the remaining menu entries.
+   The keyword argument *command* may be given a callback that is invoked with
+   the selected value, and the keyword argument *name* sets the Tk widget name.
+   Other keyword arguments are passed to the underlying :class:`Menubutton`
+   and may override its default appearance.
+
+   .. method:: destroy()
+
+      Destroy the widget, also cleaning up the associated pop-up menu.
+
+   .. versionchanged:: 3.14
+      Added support for the *name* keyword argument.
+
+   .. versionchanged:: next
+      Other :class:`Menubutton` options can now be passed as keyword arguments.
+
+
+
+.. class:: PanedWindow(master=None, cnf={}, **kw)
+
+   A :class:`!PanedWindow` is a geometry-manager widget that arranges any
+   number of child *panes* in a row (when *orient* is ``'horizontal'``) or a
+   column (when *orient* is ``'vertical'``).
+   Each pane holds one widget, and each pair of adjacent panes is separated by
+   a movable *sash* that the user can drag with the mouse to resize the widgets
+   on either side of it.
+   Inherits from :class:`Widget`.
+
+   The *orient* option selects the layout direction, *sashwidth* sets the width
+   of each sash and *sashrelief* its relief.
+   When *showhandle* is true a small handle is drawn on each sash that the user
+   can grab to drag it.
+   Refer to the Tk ``panedwindow`` manual page for the full list of options.
+
+   .. method:: add(child, **kw)
+
+      Add *child* to the panedwindow as a new pane, placed after any existing
+      panes.
+      The keyword arguments specify per-pane management options for *child*;
+      they may be any of the options accepted by :meth:`paneconfigure`.
+
+   .. method:: forget(child)
+      :no-typesetting:
+
+   .. method:: remove(child)
+
+      Remove the pane containing *child* from the panedwindow.
+      All geometry management options for *child* are forgotten.
+      :meth:`forget` is an alias of :meth:`!remove`.
+      This shadows the inherited geometry-manager :meth:`!forget`;
+      use :meth:`~Pack.pack_forget`, :meth:`~Grid.grid_forget` or
+      :meth:`~Place.place_forget` to remove the widget itself from its manager.
+
+   .. method:: panes()
+
+      Return a tuple of the widgets managed by the panedwindow, one per pane,
+      in order.
+
+   .. method:: panecget(child, option)
+
+      Return the current value of the management option *option* for the pane
+      containing *child*.
+      *option* may be any value allowed by :meth:`paneconfigure`.
+
+   .. method:: paneconfig(tagOrId, cnf=None, **kw)
+      :no-typesetting:
+
+   .. method:: paneconfigure(tagOrId, cnf=None, **kw)
+
+      Query or modify the management options of the pane containing the widget
+      *tagOrId*.
+      With no options, it returns a dictionary describing all of the available
+      options for the pane; given a single option name as a string, it returns
+      a description of that one option; otherwise it sets the given options.
+      The supported options include *after* and *before* (insert the pane after
+      or before another managed window), *height* and *width* (the outer
+      dimensions of the window, including any border), *minsize* (the minimum
+      size in the paned dimension), *padx* and *pady* (extra space to leave on
+      each side of the window), *sticky* (position or stretch the window within
+      an oversized pane, using a string of the characters ``n``, ``s``, ``e``
+      and ``w``), *hide* (hide the pane while keeping it in the list of panes)
+      and *stretch* (how extra space is allocated to the pane: one of
+      ``'always'``, ``'first'``, ``'last'``, ``'middle'`` or ``'never'``).
+      :meth:`paneconfig` is an alias of :meth:`!paneconfigure`.
+
+   .. method:: identify(x, y)
+
+      Identify the panedwindow component underneath the point given by *x* and
+      *y*, in window coordinates.
+      If the point is over a sash or a sash handle, the result is a two-element
+      tuple containing the index of the sash or handle and a word indicating
+      whether it is over a sash or a handle, such as ``(0, 'sash')`` or
+      ``(2, 'handle')``.
+      If the point is over any other part of the panedwindow, the result is an
+      empty string.
+
+   .. method:: sash(*args)
+
+      Query or change the position of the sashes in the panedwindow.
+      This is a thin wrapper around the Tk ``sash`` subcommand; the convenience
+      methods :meth:`sash_coord`, :meth:`sash_mark` and :meth:`sash_place`
+      should normally be used instead.
+
+   .. method:: sash_coord(index)
+
+      Return the current x and y coordinate pair for the sash given by *index*,
+      which must be an integer between 0 and one less than the number of panes
+      in the panedwindow.
+      The coordinates returned are those of the top left corner of the region
+      containing the sash.
+
+   .. method:: sash_mark(index)
+
+      Record the current mouse position for the sash given by *index*, for use
+      together with later sash-drag operations to move the sash.
+
+   .. method:: sash_place(index, x, y)
+
+      Place the sash given by *index* at the coordinates *x* and *y*.
+
+   .. method:: proxy(*args)
+
+      Query or change the position of the sash proxy, the "ghost" sash shown
+      while a sash is being dragged with non-opaque resizing.
+      This is a thin wrapper around the Tk ``proxy`` subcommand; the
+      convenience methods :meth:`proxy_coord`, :meth:`proxy_forget` and
+      :meth:`proxy_place` should normally be used instead.
+
+   .. method:: proxy_coord()
+
+      Return a tuple containing the x and y coordinates of the most recent
+      proxy location.
+
+   .. method:: proxy_forget()
+
+      Remove the proxy from the display.
+
+   .. method:: proxy_place(x, y)
+
+      Place the proxy at the coordinates *x* and *y*.
+
+
+.. class:: Radiobutton(master=None, cnf={}, **kw)
+
+   A :class:`!Radiobutton` widget displays a textual string, bitmap or image
+   together with a diamond or circular indicator, and selects one choice out of
+   several.
+   It has all the behavior of a simple button and, in addition, can be
+   selected: typically several radiobuttons share a single *variable*, and
+   selecting one sets that variable to the radiobutton's *value*; each
+   radiobutton also monitors the variable and automatically selects or
+   deselects itself when the variable changes.
+   Inherits from :class:`Widget`.
+   In addition to the standard widget options, a radiobutton accepts the
+   options documented in the Tk ``radiobutton`` manual page, such as
+   *variable*, *value* and *command*.
+
+   .. method:: invoke()
+
+      Do just what would happen if the user pressed the radiobutton with the
+      mouse: select the button and invoke the associated command, if there is
+      one.
+      Return the result of the command, or an empty string if no command is
+      associated with the radiobutton.
+      This is ignored if the radiobutton's state is ``disabled``.
+
+   .. method:: select()
+
+      Select the radiobutton and set the associated variable to the value
+      corresponding to this widget.
+
+   .. method:: deselect()
+
+      Deselect the radiobutton and set the associated variable to an empty
+      string.
+      If this radiobutton was not currently selected, this has no effect.
+
+   .. method:: flash()
+
+      Flash the radiobutton by redisplaying it several times, alternating
+      between the active and normal colors.
+      At the end of the flash the radiobutton is left in the same normal or
+      active state as when the method was called.
+      This is ignored if the radiobutton's state is ``disabled``.
+
+
+.. class:: Scale(master=None, cnf={}, **kw)
+
+   A :class:`!Scale` widget lets the user select a numerical value by moving a
+   slider along a trough.
+   It can be oriented vertically or horizontally and can optionally display a
+   label and the current value.
+   Inherits from :class:`Widget`.
+
+   In addition to the standard widget options, a scale accepts the options
+   documented in the Tk ``scale`` manual page, such as *from_*, *to*,
+   *resolution*, *orient*, *tickinterval*, *variable* and *command*.
+   As elsewhere in :mod:`!tkinter`, the leading ``-`` of the Tk option name is
+   dropped; *from* is spelled ``from_`` because :keyword:`from` is a Python
+   keyword.
+
+   With a non-integer *resolution*, see :ref:`numeric values and the locale
+   <tkinter-numeric-locale>`.
+
+   .. method:: get()
+
+      Return the current value of the scale.
+      The result is an integer if the scale's *resolution* yields whole
+      numbers, and a float otherwise.
+
+   .. method:: set(value)
+
+      Set the scale to *value*, moving the slider accordingly.
+      This has no effect if the scale is disabled.
+
+   .. method:: coords(value=None)
+
+      Return a tuple ``(x, y)`` giving the pixel coordinates, relative to the
+      widget, of the point on the centerline of the trough that corresponds to
+      *value*.
+      If *value* is omitted, the scale's current value is used.
+
+   .. method:: identify(x, y)
+
+      Return a string describing the part of the scale at the pixel coordinates
+      *x*, *y*: ``'slider'``, ``'trough1'`` (the part of the trough above or to
+      the left of the slider), ``'trough2'`` (below or to the right of the
+      slider), or an empty string if the point is not over any of these
+      elements.
+
+
+.. class:: Scrollbar(master=None, cnf={}, **kw)
+
+   A :class:`!Scrollbar` widget displays a slider and two arrows that let the
+   user scroll an associated widget, such as a :class:`Listbox`, :class:`Text`,
+   :class:`Canvas` or :class:`Entry`.
+   It is connected to the scrolled widget by setting that widget's
+   *xscrollcommand* or *yscrollcommand* option to the scrollbar's :meth:`set`
+   method, and the scrollbar's *command* option to the scrolled widget's
+   :meth:`~XView.xview` or :meth:`~YView.yview` method.
+   Inherits from :class:`Widget`.
+
+   .. method:: get()
+
+      Return the current scrollbar settings as a tuple ``(first, last)`` of two
+      fractions between 0 and 1, describing the portion of the document that is
+      currently visible, as last passed to :meth:`set`.
+
+   .. method:: set(first, last)
+
+      Set the scrollbar.
+      *first* and *last* are fractions between 0 and 1 giving the positions of
+      the start and end of the visible portion of the associated document.
+      This method is normally registered as the scrolled widget's
+      *xscrollcommand* or *yscrollcommand* and called by that widget.
+
+   .. method:: activate(index=None)
+
+      Mark the element *index* (one of ``'arrow1'``, ``'slider'`` or
+      ``'arrow2'``) as active, displaying it according to the
+      *activebackground* and *activerelief* options.
+      If *index* is omitted, return the name of the currently active element,
+      or ``None`` if no element is active.
+
+      .. versionchanged:: 3.5
+         The *index* argument is now optional.
+
+   .. method:: delta(deltax, deltay)
+
+      Return a float indicating the fractional change in the scrollbar setting
+      that corresponds to moving the slider by *deltax* pixels horizontally
+      (for horizontal scrollbars) or *deltay* pixels vertically (for vertical
+      scrollbars).
+
+   .. method:: fraction(x, y)
+
+      Return a float between 0 and 1 indicating where the point at pixel
+      coordinates *x*, *y* lies in the trough: 0 corresponds to the top or left
+      of the trough and 1 to the bottom or right.
+
+   .. method:: identify(x, y)
+
+      Return the name of the element under the pixel coordinates *x*, *y* (such
+      as ``'arrow1'``), or an empty string if the point does not lie in any
+      element of the scrollbar.
+
+
+.. class:: Spinbox(master=None, cnf={}, **kw)
+
+   A :class:`!Spinbox` widget is an :class:`Entry`-like widget with a pair of
+   up/down arrow buttons that let the user step through a range of values in
+   addition to editing the value directly.
+   The set of values may be a numeric range given by the *from_*, *to* and
+   *increment* options, or an explicit list of strings given by the *values*
+   option (which takes precedence over the range).
+   Each time an arrow is invoked the *command* callback, if any, is called; the
+   *wrap* option controls whether stepping past either end of the range wraps
+   around to the other end; the *format* option specifies how numeric values
+   are formatted; and the *validate* option enables validation of the entered
+   text.
+   Inherits from :class:`Widget` and :class:`XView`.
+
+   With a non-integer *increment*, see :ref:`numeric values and the locale
+   <tkinter-numeric-locale>`.
+
+   Many of the methods take an *index* argument identifying a character in the
+   spinbox's string.
+   As described in the Tk ``spinbox`` manual page, *index* may be a numeric
+   index (counting from 0), ``'anchor'`` (the selection anchor point),
+   ``'end'`` (just after the last character), ``'insert'`` (the character just
+   after the insertion cursor), ``'sel.first'`` or ``'sel.last'`` (the ends of
+   the selection), or ``@x`` (the character covering pixel x-coordinate *x* in
+   the window).
+
+   .. method:: get()
+
+      Return the spinbox's string.
+
+   .. method:: insert(index, s)
+
+      Insert the characters of the string *s* just before the character given
+      by *index*.
+
+   .. method:: delete(first, last=None)
+
+      Delete one or more characters of the spinbox.
+      *first* is the index of the first character to delete, and *last* is the
+      index of the character just after the last one to delete.
+      If *last* is omitted, a single character at *first* is deleted.
+
+   .. method:: icursor(index)
+
+      Arrange for the insertion cursor to be displayed just before the
+      character given by *index*.
+
+   .. method:: index(index)
+
+      Return the numerical index corresponding to *index*, as a string.
+
+   .. method:: bbox(index)
+
+      Return a tuple of four integers ``(x, y, width, height)`` describing the
+      bounding box of the character given by *index*.
+      *x* and *y* are the pixel coordinates of the upper-left corner of the
+      character relative to the widget, and *width* and *height* are its size
+      in pixels.
+      The bounding box may refer to a region outside the visible area of the
+      window.
+
+      This shadows the inherited :meth:`!Misc.bbox`;
+      use :meth:`~Misc.grid_bbox` for the grid bounding box.
+
+   .. method:: identify(x, y)
+
+      Return the name of the window element at the pixel coordinates *x*, *y*:
+      one of ``'buttondown'``, ``'buttonup'``, ``'entry'`` or ``'none'``.
+
+   .. method:: invoke(element)
+
+      Invoke the spin button given by *element*, either ``'buttonup'`` or
+      ``'buttondown'``, triggering the action associated with it.
+
+   .. method:: scan(*args)
+
+      A thin wrapper around the Tk ``scan`` widget subcommand, used to
+      implement fast dragging of the view: ``scan('mark', x)`` records *x* and
+      the current view, and ``scan('dragto', x)`` adjusts the view relative to
+      that mark.
+      The :meth:`scan_mark` and :meth:`scan_dragto` methods wrap the two forms.
+
+   .. method:: scan_mark(x)
+
+      Record *x* and the current view in the spinbox window, for use with a
+      later :meth:`scan_dragto` call.
+      This is typically associated with a mouse button press in the widget.
+
+   .. method:: scan_dragto(x)
+
+      Adjust the view by 10 times the difference between *x* and the *x* passed
+      to the last :meth:`scan_mark` call.
+      This is typically associated with mouse motion events, producing the
+      effect of dragging the spinbox at high speed through the window.
+
+   .. method:: selection(*args)
+
+      A thin wrapper around the Tk ``selection`` widget subcommand, used to
+      adjust the selection within the spinbox.
+      It has several forms depending on the first argument, such as
+      ``selection('adjust', index)``, ``selection('clear')``,
+      ``selection('element', ?elem?)``, ``selection('from', index)``,
+      ``selection('present')``, ``selection('range', start, end)`` and
+      ``selection('to', index)``.
+      The :meth:`selection_adjust`, :meth:`selection_clear`,
+      :meth:`selection_element`, :meth:`selection_from`,
+      :meth:`selection_present`, :meth:`selection_range` and
+      :meth:`selection_to` methods wrap these forms.
+
+   .. method:: selection_adjust(index)
+
+      Locate the end of the selection nearest to the character given by *index*
+      and adjust that end of the selection to be at *index* (including but not
+      going beyond *index*).
+      The other end becomes the anchor point for future :meth:`selection_to`
+      calls.
+      If the selection is not currently in the spinbox, a new selection is
+      created to include the characters between *index* and the most recent
+      anchor point, inclusive.
+
+   .. method:: selection_clear()
+
+      Clear the selection if it is currently in this widget.
+      If the selection is not in this widget, the method has no effect.
+
+      .. note::
+
+         This shadows the inherited :meth:`Misc.selection_clear`,
+         which clears the X selection;
+         that method is not available on a :class:`Spinbox`.
+
+   .. method:: selection_element(element=None)
+
+      Set or get the currently selected element.
+      If *element* (one of ``'buttonup'``, ``'buttondown'`` or ``'none'``) is
+      given, that spin button is selected and displayed depressed; otherwise
+      the name of the currently selected element is returned.
+
+   .. method:: selection_from(index)
+
+      Set the selection anchor point to just before the character given by
+      *index*, without changing the selection itself.
+
+      .. versionadded:: 3.8
+
+
+   .. method:: selection_present()
+
+      Return ``True`` if there are characters selected in the spinbox,
+      ``False`` otherwise.
+
+      .. versionadded:: 3.8
+
+
+   .. method:: selection_range(start, end)
+
+      Set the selection to include the characters starting with the one indexed
+      by *start* and ending with the one just before *end*.
+      If *end* refers to the same character as *start* or an earlier one, the
+      selection is cleared.
+
+      .. versionadded:: 3.8
+
+
+   .. method:: selection_to(index)
+
+      Set the selection between *index* and the anchor point.
+      If *index* is before the anchor point, the selection runs from *index* up
+      to but not including the anchor point; if it is after, the selection runs
+      from the anchor point up to but not including *index*; if it is the same,
+      nothing happens.
+      The anchor point is the one set by the most recent :meth:`selection_from`
+      or :meth:`selection_adjust` call.
+      If the selection is not in this widget, a new selection is created using
+      the most recent anchor point.
+
+      .. versionadded:: 3.8
+
+   .. method:: validate()
+
+      Force an evaluation of the command given by the *validatecommand* option,
+      independently of the conditions specified by the *validate* option, and
+      return whether the value is considered valid.
+
+      .. versionadded:: next
+
+
+
+.. class:: Text(master=None, cnf={}, **kw)
+
+   A :class:`!Text` widget displays and edits multi-line text.
+   Portions of the text may be styled with **tags**, particular positions may
+   be annotated with floating **marks**, and arbitrary images and other widgets
+   may be embedded in the text.
+   The widget also provides an unlimited undo/redo mechanism and supports peer
+   widgets that share the same underlying data.
+   Inherits from :class:`Widget`, :class:`XView` and :class:`YView`, so the
+   view can be scrolled horizontally and vertically with :meth:`~XView.xview`
+   and :meth:`~YView.yview`.
+   Refer to the Tk ``text`` manual page for the full list of options.
+
+   Most of the methods take one or more *index* arguments that identify a
+   position within the text.
+   As described in the Tk ``text`` manual page, an index is a string consisting
+   of a base, optionally followed by one or more modifiers.
+   The base may be ``'line.char'`` (line *line*, character *char*, where lines
+   are counted from 1 and characters within a line from 0; ``'line.end'``
+   refers to the newline ending the line), ``'end'`` (the position just after
+   the last newline), the name of a mark, ``'tag.first'`` or ``'tag.last'``
+   (the first character tagged with *tag*, or the position just after the last
+   such character), the name of an embedded image or window, or ``@x,y`` (the
+   character covering pixel coordinates *x*, *y* in the widget).
+   A modifier such as ``'+5 chars'``, ``'-3 lines'``, ``'linestart'``,
+   ``'lineend'``, ``'wordstart'`` or ``'wordend'`` adjusts the index relative
+   to its base; several modifiers may be combined and are applied from left to
+   right, for example ``'insert wordstart - 1 c'``.
+
+   .. method:: insert(index, chars, *args)
+
+      Insert the string *chars* just before the character at *index* (if
+      *index* is ``'end'``, just before the final newline).
+      By default the new text inherits any tags present on both sides of the
+      insertion point.
+      If *args* is given, it consists of alternating *tagList*, *chars* values:
+      the preceding *chars* receives exactly the tags listed (a tag list may be
+      a single tag name or a sequence of names), overriding the surrounding
+      tags.
+
+   .. method:: delete(index1, index2=None)
+
+      Delete the range of characters from *index1* up to but not including
+      *index2*.
+      If *index2* is omitted, the single character at *index1* is deleted.
+      The widget always keeps a newline as its last character, so a deletion
+      that would remove it is adjusted accordingly.
+
+   .. method:: replace(index1, index2, chars, *args)
+
+      Replace the range of characters from *index1* up to but not including
+      *index2* with *chars*.
+      This is equivalent to a :meth:`delete` followed by an :meth:`insert` at
+      *index1*; *args* is interpreted as for :meth:`insert`.
+
+      .. versionadded:: 3.3
+
+   .. method:: get(index1, index2=None)
+
+      Return the text from *index1* up to but not including *index2* as a
+      string.
+      If *index2* is omitted, return the single character at *index1*.
+      Embedded images and windows are omitted from the result.
+
+   .. method:: index(index)
+
+      Return the position corresponding to *index* in the canonical
+      ``'line.char'`` form.
+
+   .. method:: compare(index1, op, index2)
+
+      Compare the positions of *index1* and *index2* using the relational
+      operator *op*, which must be one of ``'<'``, ``'<='``, ``'=='``,
+      ``'>='``, ``'>'`` or ``'!='``, and return the boolean result.
+
+   .. method:: count(index1, index2, *options, return_ints=False)
+
+      Count the number of items of the requested kinds between *index1* and
+      *index2*; the count is negative if *index1* is after *index2*.
+      Each of *options* names a kind of item to count: ``'chars'``,
+      ``'displaychars'``, ``'displayindices'``, ``'displaylines'``,
+      ``'indices'``, ``'lines'``, ``'xpixels'`` or ``'ypixels'`` (the default,
+      used when no option is given, is ``'indices'``).
+      The pseudo-option ``'update'`` forces any out-of-date layout information
+      to be recalculated before the following options are evaluated.
+      When *return_ints* is true and a single counting option is given, return
+      a plain integer; otherwise return a tuple with one integer per counting
+      option (or ``None`` if the result is empty).
+
+      .. versionadded:: 3.3
+
+      .. versionchanged:: 3.13
+         Added the *return_ints* parameter.
+
+
+   .. method:: see(index)
+
+      Adjust the view so that the character given by *index* is visible.
+      If it is already visible the method has no effect; if it is a short
+      distance out of view the widget scrolls just enough to bring it to the
+      nearest edge, otherwise it scrolls to center *index* in the window.
+
+   .. method:: bbox(index)
+
+      Return a tuple ``(x, y, width, height)`` giving the bounding box, in
+      pixels, of the visible part of the character at *index*, or ``None`` if
+      that character is not visible on the screen.
+
+      This shadows the inherited :meth:`!Misc.bbox`;
+      use :meth:`~Misc.grid_bbox` for the grid bounding box.
+
+   .. method:: dlineinfo(index)
+
+      Return a tuple ``(x, y, width, height, baseline)`` describing the display
+      line that contains *index*: the first four values give the bounding box
+      of the line in pixels and *baseline* gives the offset of the baseline
+      measured down from the top of the area.
+      Return ``None`` if that display line is not visible on the screen.
+
+   .. method:: mark_set(markName, index)
+
+      Set the mark named *markName* to the position just before the character
+      at *index*, creating the mark if it does not already exist.
+      A mark created this way has right gravity by default.
+
+   .. method:: mark_unset(*markNames)
+
+      Remove each of the marks named in *markNames*.
+      The special ``insert`` and ``current`` marks may not be removed.
+
+   .. method:: mark_names()
+
+      Return a tuple of the names of all marks currently set in the widget.
+
+   .. method:: mark_gravity(markName, direction=None)
+
+      If *direction* is omitted, return the gravity of mark *markName*, either
+      ``'left'`` or ``'right'``.
+      Otherwise set its gravity to *direction*.
+      The gravity determines on which side of the mark text inserted at the
+      mark's position appears: a mark with right gravity (the default) stays to
+      the right of such text.
+
+   .. method:: mark_next(index)
+
+      Return the name of the first mark at or after *index*, or ``None`` if
+      there is none.
+      When *index* is the name of a mark, the search starts just after that
+      mark.
+
+   .. method:: mark_previous(index)
+
+      Return the name of the last mark at or before *index*, or ``None`` if
+      there is none.
+      When *index* is the name of a mark, the search starts just before that
+      mark.
+
+   .. method:: tag_add(tagName, index1, *args)
+
+      Add the tag *tagName* to the range of characters from *index1* up to but
+      not including the next index in *args*.
+      Further pairs of indices may follow in *args* to tag additional ranges; a
+      trailing single index tags just the character at that index.
+
+   .. method:: tag_remove(tagName, index1, index2=None)
+
+      Remove the tag *tagName* from the characters from *index1* up to but not
+      including *index2* (or from the single character at *index1* if *index2*
+      is omitted).
+      The tag itself continues to exist even if no characters carry it.
+
+   .. method:: tag_delete(*tagNames)
+
+      Delete each of the tags named in *tagNames*, removing them from all
+      characters and discarding their options and bindings.
+
+   .. method:: tag_config(tagName, cnf=None, **kw)
+      :no-typesetting:
+
+   .. method:: tag_configure(tagName, cnf=None, **kw)
+
+      Query or modify the configuration options of the tag *tagName*.
+      This mirrors :meth:`~Misc.configure`, except that it applies to a tag
+      rather than to the widget as a whole: with no options it returns a
+      dictionary describing the current options, otherwise it sets the given
+      options.
+      Defining a tag this way also gives it a priority higher than any existing
+      tag.
+
+      The supported tag options, all controlling the appearance of the tagged
+      text, are:
+
+      *font*
+         The font to use for the text.
+
+      *foreground*
+         The color to use for the text.
+
+      *background*
+         The color to use for the area behind the text.
+
+      *fgstipple*, *bgstipple*
+         Bitmaps used to stipple the foreground (text) and the background;
+         only well supported on X11.
+
+      *borderwidth*
+         The width of the border drawn around the text according to *relief*
+         (default ``0``).
+
+      *relief*
+         The 3-D appearance of the text's border: ``'flat'`` (the default),
+         ``'raised'``, ``'sunken'``, ``'ridge'``, ``'groove'`` or ``'solid'``.
+
+      *offset*
+         How far the text is raised above (or, if negative, lowered below) the
+         baseline, for superscripts and subscripts.
+
+      *underline*
+         Whether to underline the text.
+
+      *underlinefg*
+         The color of the underline; it defaults to the text color.
+
+      *overstrike*
+         Whether to draw a line through the middle of the text.
+
+      *overstrikefg*
+         The color of the overstrike line; it defaults to the text color.
+
+      *elide*
+         Whether the text is elided (hidden).
+
+      *justify*
+         How to justify the first character of a display line: ``'left'`` (the
+         default), ``'right'`` or ``'center'``.
+
+      *wrap*
+         How to wrap lines that are too long: ``'char'``, ``'word'`` or
+         ``'none'``.
+
+      *lmargin1*, *lmargin2*
+         The indentation, in pixels, of the first display line of a logical
+         line and of the remaining display lines.
+
+      *lmargincolor*
+         The color of the left margin area.
+
+      *rmargin*
+         The right-hand margin, in pixels.
+
+      *rmargincolor*
+         The color of the right margin area.
+
+      *spacing1*, *spacing2*, *spacing3*
+         Extra space, in pixels, above the first display line of a logical
+         line, between its display lines, and below its last display line.
+
+      *tabs*
+         The set of tab stops, in the same form as the widget's *tabs* option.
+
+      *tabstyle*
+         How tab stops are interpreted: ``'tabular'`` or ``'wordprocessor'``.
+
+      *selectbackground*, *selectforeground*
+         The background and foreground colors used for the text while it is
+         selected.
+
+      .. note::
+
+         Tk 8.6 added the *lmargincolor*, *overstrikefg*, *rmargincolor*,
+         *selectbackground*, *selectforeground* and *underlinefg* options.
+
+      :meth:`tag_config` is an alias of :meth:`!tag_configure`.
+
+   .. method:: tag_cget(tagName, option)
+
+      Return the current value of the configuration option *option* for the tag
+      *tagName*.
+
+   .. method:: tag_names(index=None)
+
+      If *index* is omitted, return a tuple of the names of all tags defined in
+      the widget; otherwise return only the names of the tags applied to the
+      character at *index*.
+      The names are ordered from lowest to highest priority.
+
+   .. method:: tag_ranges(tagName)
+
+      Return a tuple of indices describing all ranges of text tagged with
+      *tagName*.
+      The result alternates start and end indices, so that elements ``2*i`` and
+      ``2*i+1`` bound the *i*-th range.
+
+   .. method:: tag_nextrange(tagName, index1, index2=None)
+
+      Search forward from *index1* (up to *index2* if given) for the first
+      range of characters tagged with *tagName*, and return a two-element tuple
+      of its start and end indices, or an empty tuple if there is no such
+      range.
+
+   .. method:: tag_prevrange(tagName, index1, index2=None)
+
+      Search backward from *index1* (down to *index2* if given) for the nearest
+      preceding range of characters tagged with *tagName*, and return a
+      two-element tuple of its start and end indices, or an empty tuple if
+      there is no such range.
+
+   .. method:: tag_raise(tagName, aboveThis=None)
+
+      Raise the priority of tag *tagName* so that it is just above the priority
+      of *aboveThis*, or to the highest priority of all tags if *aboveThis* is
+      omitted.
+      When the display options of overlapping tags conflict, the
+      higher-priority tag wins.
+
+   .. method:: tag_lower(tagName, belowThis=None)
+
+      Lower the priority of tag *tagName* so that it is just below the priority
+      of *belowThis*, or to the lowest priority of all tags if *belowThis* is
+      omitted.
+
+   .. method:: tag_bind(tagName, sequence, func, add=None)
+
+      Bind the event *sequence* on characters tagged with *tagName* to the
+      callback *func*, so that *func* is invoked when that event occurs over
+      such a character.
+      If *add* is true the binding is added alongside any existing bindings for
+      *sequence*, otherwise it replaces them.
+      Works like :meth:`~Misc.bind` and returns the identifier of the new
+      binding.
+
+   .. method:: tag_unbind(tagName, sequence, funcid=None)
+
+      Remove the bindings of the event *sequence* on characters tagged with
+      *tagName*.
+      If *funcid* is given, only that binding (as returned by :meth:`tag_bind`)
+      is removed and its callback is unregistered.
+
+      .. versionchanged:: 3.13
+         If *funcid* is given, only that callback is unbound.
+
+
+   .. method:: image_create(index, cnf={}, **kw)
+
+      Embed an image at *index* and return the name assigned to this image
+      instance, which may then be used as an index or passed to the other
+      ``image_*`` methods.
+      The options, given in *cnf* and *kw*, include *image* (the Tk image to
+      display), *name* (a base name for the instance), *align*, *padx* and
+      *pady*.
+
+   .. method:: image_cget(index, option)
+
+      Return the current value of the configuration option *option* for the
+      embedded image at *index*.
+
+   .. method:: image_configure(index, cnf=None, **kw)
+
+      Query or modify the configuration options of the embedded image at
+      *index*, like :meth:`~Misc.configure` but applied to that image.
+
+   .. method:: image_names()
+
+      Return a tuple of the names of all images embedded in the widget.
+
+      .. note::
+
+         This shadows the inherited :meth:`Misc.image_names`,
+         which returns the names of all images in the Tcl interpreter;
+         that method is not available on a :class:`Text`.
+
+   .. method:: window_create(index, cnf={}, **kw)
+
+      Embed a window (any widget) at *index*.
+      The options, given in *cnf* and *kw*, include *window* (the widget to
+      embed), *create* (a callback that creates the widget on demand), *align*,
+      *stretch*, *padx* and *pady*.
+      The embedded widget must be a descendant of the text widget's parent.
+
+   .. method:: window_cget(index, option)
+
+      Return the current value of the configuration option *option* for the
+      embedded window at *index*.
+
+   .. method:: window_config(index, cnf=None, **kw)
+      :no-typesetting:
+
+   .. method:: window_configure(index, cnf=None, **kw)
+
+      Query or modify the configuration options of the embedded window at
+      *index*, like :meth:`~Misc.configure` but applied to that window.
+
+      :meth:`window_config` is an alias of :meth:`!window_configure`.
+
+   .. method:: window_names()
+
+      Return a tuple of the names of all windows embedded in the widget.
+
+   .. method:: edit(*args)
+
+      Low-level wrapper around the Tk ``edit`` widget command that controls the
+      undo/redo mechanism and the modified flag; *args* is the ``edit``
+      subcommand and its arguments.
+      The :meth:`!edit_\*` methods below are thin wrappers around it and are
+      usually more convenient.
+
+   .. method:: edit_modified(arg=None)
+
+      If *arg* is omitted, return the current state of the modified flag as
+      ``0`` or ``1``; the flag is set automatically whenever the text is
+      inserted or deleted.
+      Otherwise set the flag to the boolean *arg*.
+
+   .. method:: edit_canundo()
+
+      Return ``True`` if there is an edit action on the undo stack that can be
+      undone, and ``False`` otherwise.
+
+      .. versionadded:: next
+
+   .. method:: edit_canredo()
+
+      Return ``True`` if there is an edit action on the redo stack that can be
+      reapplied, and ``False`` otherwise.
+
+      .. versionadded:: next
+
+   .. method:: edit_undo()
+
+      Undo the most recent edit action, that is, all the inserts and deletes
+      recorded on the undo stack since the previous separator, and move it to
+      the redo stack.
+      Raises :exc:`TclError` if the undo stack is empty.
+      Has no effect unless the *undo* option is true.
+      Since Tk 9.0, returns a tuple of indices delimiting the ranges of text
+      that were changed.
+
+   .. method:: edit_redo()
+
+      Reapply the most recently undone edit action, provided no further edits
+      have been made since, and move it back to the undo stack.
+      Raises :exc:`TclError` if the redo stack is empty.
+      Has no effect unless the *undo* option is true.
+      Since Tk 9.0, returns a tuple of indices delimiting the ranges of text
+      that were changed.
+
+   .. method:: edit_reset()
+
+      Clear the undo and redo stacks.
+
+   .. method:: edit_separator()
+
+      Push a separator onto the undo stack, marking a boundary between edit
+      actions for undo and redo.
+      Has no effect unless the *undo* option is true.
+      Separators are inserted automatically when the *autoseparators* option is
+      true.
+
+   .. method:: search(pattern, index, stopindex=None, forwards=None, backwards=None, exact=None, regexp=None, nocase=None, count=None, elide=None, *, nolinestop=None, strictlimits=None)
+
+      Search for *pattern* starting at *index* and return the index of the
+      first character of the first match, or an empty string if there is no
+      match.
+      Searching stops at *stopindex* if given; otherwise it wraps around the
+      ends of the text until the starting position is reached again.
+      The following boolean keyword flags control the search: *forwards* or
+      *backwards* select the direction (forward is the default); *exact* (the
+      default) or *regexp* select literal or regular-expression matching;
+      *nocase* makes the match case-insensitive; *elide* causes hidden text to
+      be searched as well; *nolinestop* (regexp only) lets ``.`` and ``[^``
+      match newlines; and *strictlimits* requires the whole match to lie within
+      *index* and *stopindex*.
+      If *count* is a :class:`Variable`, the number of index positions in the
+      match is stored in it.
+
+      .. versionchanged:: 3.15
+         Added the *nolinestop* and *strictlimits* parameters.
+
+
+   .. method:: search_all(pattern, index, stopindex=None, *, forwards=None, backwards=None, exact=None, regexp=None, nocase=None, count=None, elide=None, nolinestop=None, overlap=None, strictlimits=None)
+
+      Like :meth:`search`, but find every match in the searched range and
+      return a tuple of the starting indices of all matches (empty if there are
+      none).
+      By default overlapping matches are not reported; passing a true *overlap*
+      returns every match that is not wholly contained in another.
+      If *count* is a :class:`Variable`, it receives a list with one element
+      per match.
+
+      .. versionadded:: 3.15
+
+
+   .. method:: scan_mark(x, y)
+
+      Record *x*, *y* and the current view, for use with later
+      :meth:`scan_dragto` calls.
+      This is typically bound to a mouse button press in the widget.
+
+   .. method:: scan_dragto(x, y)
+
+      Scroll the widget by 10 times the difference between *x*, *y* and the
+      coordinates passed to the last :meth:`scan_mark` call.
+      This is typically bound to mouse motion events, producing the effect of
+      dragging the text at high speed through the window.
+
+   .. method:: debug(boolean=None)
+
+      If *boolean* is omitted, return whether internal consistency checks of
+      the B-tree data structure are enabled.
+      Otherwise enable or disable them.
+      The setting is shared by all text widgets and may noticeably slow down
+      widgets holding large amounts of text.
+
+   .. method:: dump(index1, index2=None, command=None, **kw)
+
+      Return the contents of the widget from *index1* up to but not including
+      *index2* (or just the segment at *index1* if *index2* is omitted),
+      including text and information about marks, tags, images and windows.
+      The result is a list of ``(key, value, index)`` triples, where *key* is
+      one of ``'text'``, ``'mark'``, ``'tagon'``, ``'tagoff'``, ``'image'`` or
+      ``'window'``.
+      By default all kinds are reported; passing any of the keyword arguments
+      *all*, *text*, *mark*, *tag*, *image* or *window* as true restricts the
+      dump to the selected kinds.
+      If *command* is given, it is called once per triple with the three values
+      as arguments and nothing is returned.
+
+   .. method:: peer_create(newPathName, cnf={}, **kw)
+
+      Create a peer text widget with the path name *newPathName* that shares
+      this widget's underlying data (text, marks, tags, images and the undo
+      stack).
+      Changes made through any peer are reflected in all of them.
+      By default the peer covers the same lines as this widget; standard text
+      options, including *startline* and *endline*, may be given to override
+      this.
+
+      .. versionadded:: 3.3
+
+   .. method:: peer_names()
+
+      Return a tuple of the path names of this widget's peers, not including
+      the widget itself.
+
+      .. versionadded:: 3.3
+
+   .. method:: sync(command=None)
+
+      Control the synchronization of the displayed view with the underlying
+      text, which may lag behind when line heights have not yet been computed
+      (for example, for lines that have never been displayed).
+      If *command* is omitted, bring the line metrics up to date immediately by
+      forcing computation of any outdated line heights, and return once they
+      are current.
+      Otherwise schedule *command* to be called, with no arguments, exactly
+      once as soon as all line heights are up to date; if there are no pending
+      calculations, it is called immediately.
+
+      .. versionadded:: next
+
+   .. method:: pendingsync()
+
+      Return ``True`` if the line height calculations are not up to date, and
+      ``False`` otherwise.
+      The ``<<WidgetViewSync>>`` virtual event fires whenever this state
+      changes, with the *detail* field set to the new value.
+
+      .. versionadded:: next
+
+   .. method:: yview_pickplace(*what)
+
+      Adjust the view so that the location given by *what* is visible.
+      This is an obsolete equivalent of :meth:`see`, which should be used
+      instead.
+
+
+Variable classes
+^^^^^^^^^^^^^^^^
+
+.. class:: Variable(master=None, value=None, name=None)
+
+   The base class for the Tk variable wrappers.
+   A Tk variable is a value stored in the Tcl interpreter that can be linked to
+   widgets through their *variable* or *textvariable* options (see
+   :ref:`coupling-widget-variables`), so that changes propagate both ways:
+   updating the variable updates every widget bound to it, and a user editing
+   such a widget updates the variable.
+
+   *master* is the widget whose Tcl interpreter owns the variable; if omitted,
+   the default root window is used.
+   *value* is the initial value; if omitted, a type-specific default is used.
+   *name* is the name of the variable in the Tcl interpreter; if omitted, a
+   unique name of the form ``'PY_VARnum'`` is generated.
+   If *name* matches an existing variable and *value* is omitted, the existing
+   value is retained.
+
+   In most cases you should use one of the typed subclasses below --
+   :class:`StringVar`, :class:`IntVar`, :class:`DoubleVar` or
+   :class:`BooleanVar` -- rather than :class:`!Variable` directly.
+
+   .. note::
+
+      When a :class:`!Variable` is garbage collected, its Tcl variable is unset.
+      Keep a reference to it for as long as a widget is linked to it, for example
+      by storing it as an attribute rather than in a local variable.
+      Otherwise Tk recreates the Tcl variable to keep the widget working, but it
+      is never unset again, leaking one Tcl variable per dropped wrapper.
+
+   .. versionchanged:: 3.10
+      Two variables now compare equal (``==``) only when they have the same
+      name, are of the same class, and belong to the same Tcl interpreter.
+
+   .. method:: get()
+
+      Return the current value of the variable.
+      For the base class the value is returned as a string; the typed
+      subclasses convert it to the appropriate Python type.
+
+   .. method:: initialize(value)
+      :no-typesetting:
+
+   .. method:: set(value)
+
+      Set the variable to *value*.
+      :meth:`initialize` is an alias of :meth:`!set`.
+
+      .. versionadded:: 3.3
+         The *initialize* spelling.
+
+   .. method:: trace_add(mode, callback)
+
+      Register *callback* to be called when the variable is accessed according
+      to *mode*.
+      *mode* is one of the strings ``'array'``, ``'read'``, ``'write'`` or
+      ``'unset'``, or a list or tuple of such strings.
+
+      When triggered, *callback* is called with three arguments: the name of
+      the Tcl variable, an index (or an empty string if the variable is not an
+      element of an array), and the *mode* that triggered the call.
+
+      Return the internal name of the registered callback, which can be passed
+      to :meth:`trace_remove`.
+
+      .. versionadded:: 3.6
+
+   .. method:: trace_remove(mode, cbname)
+
+      Remove a trace callback from the variable.
+      *mode* must match the *mode* that was passed to :meth:`trace_add`, and
+      *cbname* is the callback name returned by :meth:`trace_add`.
+
+      .. versionadded:: 3.6
+
+   .. method:: trace_info()
+
+      Return a list of ``(modes, cbname)`` pairs describing all traces
+      currently set on the variable, where *modes* is a tuple of mode strings
+      and *cbname* is the internal callback name.
+
+      .. versionadded:: 3.6
+
+   .. method:: trace(mode, callback)
+      :no-typesetting:
+
+   .. method:: trace_variable(mode, callback)
+
+      Register *callback* to be called when the variable is accessed according
+      to *mode*.
+      *mode* is one of the strings ``'r'``, ``'w'`` or ``'u'``, for read, write
+      or unset.
+      Return the internal name of the registered callback.
+      :meth:`trace` is an alias of :meth:`!trace_variable`.
+
+      .. deprecated:: 3.6
+         Use :meth:`trace_add` instead.  This method wraps a Tcl feature that
+         was removed in Tcl 9.0.
+
+   .. method:: trace_vdelete(mode, cbname)
+
+      Remove the trace callback named *cbname* registered for *mode* with
+      :meth:`trace_variable`.
+
+      .. deprecated:: 3.6
+         Use :meth:`trace_remove` instead.  This method wraps a Tcl feature
+         that was removed in Tcl 9.0.
+
+   .. method:: trace_vinfo()
+
+      Return a list of ``(mode, cbname)`` pairs for all traces set on the
+      variable with :meth:`trace_variable`.
+
+      .. deprecated:: 3.6
+         Use :meth:`trace_info` instead.  This method wraps a Tcl feature that
+         was removed in Tcl 9.0.
+
+
+.. class:: StringVar(master=None, value=None, name=None)
+
+   A :class:`Variable` subclass that holds a string.

+
+Image classes
+^^^^^^^^^^^^^
+
+.. class:: Image(imgtype, name=None, cnf={}, master=None, **kw)
+
+   Base class for Tk images.
+   *imgtype* is the Tk image type, one of ``'photo'`` or ``'bitmap'``.
+   An image is a named object that can be displayed by widgets through their
+   *image* option; deleting all references to the :class:`!Image` object
+   deletes the underlying Tk image.
+   Usually you create a :class:`PhotoImage` or :class:`BitmapImage` rather than
+   an :class:`!Image` directly.
+
+   The image's configuration options are given by *cnf* and *kw* and may be
+   queried and changed later with the mapping protocol (using ``image[key]``)
+   or with the :meth:`configure` method.
+
+   .. method:: config(**kw)
+      :no-typesetting:
+
+   .. method:: configure(**kw)
+
+      Modify one or more configuration options of the image.
+      The valid options depend on the image type; see :class:`PhotoImage` and
+      :class:`BitmapImage`.
+      :meth:`config` is an alias of :meth:`!configure`.
+
+   .. method:: height()
+
+      Return the height of the image, in pixels.
+
+   .. method:: width()
+
+      Return the width of the image, in pixels.
+
+   .. method:: type()
+
+      Return the type of the image, that is the value of *imgtype* with which
+      it was created (for example ``'photo'`` or ``'bitmap'``).
+
+
+.. class:: PhotoImage(name=None, cnf={}, master=None, **kw)
+
+   A full-color image (the Tk ``photo`` image type), stored internally with a
+   varying degree of transparency per pixel.
+   It can read and write GIF, PPM/PGM and (in Tk 8.6 and later) PNG files, read
+   SVG files (in Tk 9.0 and later), and be drawn in widgets.
+   Inherits from :class:`Image`.
+
+   The configuration options include *data* (the image contents as a string),
+   *file* (the name of a file to read the contents from), *format* (the name of
+   the file format handler), *width* and *height* (the size of the image, used
+   when building it up piece by piece), *gamma* and *palette*.
+
+   .. method:: blank()
+
+      Blank the image; that is, set the entire image to have no data, so that
+      it is displayed as transparent and the background of whatever window it
+      is displayed in shows through.
+
+   .. method:: redither()
+
+      Recalculate the dithered image in each window where it is displayed.
+      This is useful when the image data was supplied in pieces, in which case
+      the dithered image may not be exactly correct.
+
+      .. versionadded:: next
+
+   .. method:: cget(option)
+
+      Return the current value of the configuration option *option*.
+
+   .. method:: copy(*, from_coords=None, zoom=None, subsample=None)
+
+      Return a new :class:`PhotoImage` with a copy of this image.
+
+      *from_coords* specifies a rectangular sub-region of the source image to
+      be copied.
+      It must be a tuple or a list of 1 to 4 integers ``(x1, y1, x2, y2)``.
+      ``(x1, y1)`` and ``(x2, y2)`` specify diagonally opposite corners of the
+      rectangle.
+      If *x2* and *y2* are not specified, they default to the bottom-right
+      corner of the source image.
+      The pixels copied include the left and top edges of the rectangle but not
+      the bottom or right edges.
+      If *from_coords* is not given, the whole source image is copied.
+
+      If *zoom* or *subsample* are specified, the image is transformed as in
+      the :meth:`zoom` or :meth:`subsample` methods.
+      The value must be a single integer or a pair of integers.
+
+      .. versionchanged:: 3.13
+         Added the *from_coords*, *zoom* and *subsample* parameters.

+                            compositingrule=None)
+
+      Copy a region from *sourceImage* (which must be a :class:`PhotoImage`)
+      into this image, possibly with pixel zooming and/or subsampling.
+      If no options are specified, the whole of *sourceImage* is copied into
+      this image, starting at coordinates ``(0, 0)``.
+
+      *from_coords* specifies a rectangular sub-region of the source image to
+      be copied, as in the :meth:`copy` method.
+
+      *to* specifies a rectangular sub-region of the destination image to be
+      affected.
+      It must be a tuple or a list of 1 to 4 integers ``(x1, y1, x2, y2)``.
+      If *x2* and *y2* are not specified, they default to ``(x1, y1)`` plus the
+      size of the source region (after subsampling and zooming, if specified).
+      If *x2* and *y2* are specified, the source region is replicated if
+      necessary to fill the destination region in a tiled fashion.
+
+      If *shrink* is true, the size of the destination image is reduced, if
+      necessary, so that the region being copied into is at the bottom-right
+      corner of the image.
+
+      If *zoom* or *subsample* are specified, the image is transformed as in
+      the :meth:`zoom` or :meth:`subsample` methods.
+      The value must be a single integer or a pair of integers.
+
+      *compositingrule* specifies how transparent pixels in the source image
+      are combined with the destination image.
+      With ``'overlay'`` (the default), the old contents of the destination
+      image remain visible, as if the source image were printed on a piece of
+      transparent film and placed over the top of the destination.
+      With ``'set'``, the old contents of the destination image are discarded
+      and the source image is used as-is.

+
+      *format* specifies the name of the image file format handler to use.
+      If it is not given, the data is returned as a tuple (one element per row)

+      colors in ``#RRGGBB`` format.
+
+      *from_coords* specifies a rectangular region of the image to be returned.
+      It must be a tuple or a list of 1 to 4 integers ``(x1, y1, x2, y2)``.

+      If all four coordinates are given, they specify diagonally opposite
+      corners of the region, including ``(x1, y1)`` and excluding ``(x2, y2)``.
+      If *from_coords* is not given, the whole image is returned.

+      example ``"{red green} {blue yellow}"``).
+
+      *to* specifies the coordinates of the region of the image into which the

+   For pixels where the mask is zero the image displays nothing; for other
+   pixels it displays the foreground color where the source is one and the
+   background color where the source is zero.
+   If *background* is set to an empty string, the background pixels are
+   transparent.
+
+   :class:`!BitmapImage` has no methods of its own beyond those inherited from

+
+
+Other classes
+^^^^^^^^^^^^^
+
+.. class:: Event()
+
+   A container for the attributes of an event passed to a callback bound with
+   :meth:`Misc.bind`.
+   An :class:`!Event` instance has the following attributes, each corresponding
+   to a field of the underlying Tk event; depending on the event type, some
+   attributes may be set to the string ``'??'`` to indicate that they are not
+   meaningful.
+   See :ref:`bindings-and-events`.
+
+   .. attribute:: serial
+
+      The serial number of the event.

+
+      The keycode of the key that was pressed or released.
+
+   .. attribute:: state
+
+      The state of the event, as a number (for most events) or a string (for
+      ``Visibility`` events).
+
+   .. attribute:: time
+
+      The timestamp of the event, in milliseconds.
+
+   .. attribute:: x
+                  y

+      The pointer position relative to the top-left corner of the screen, in
+      pixels.
+
+   .. attribute:: char
+
+      The character typed, as a string (for key events).
+
+   .. attribute:: send_event
+
+      ``True`` if the event was sent by another application.
+
+   .. attribute:: keysym
+
+      The symbolic name of the key that was pressed or released.
+
+   .. attribute:: keysym_num
+
+      The numeric value of :attr:`keysym`.
+
+   .. attribute:: type
+
+      The :class:`EventType` of the event.
+
+   .. attribute:: widget
+
+      The widget on which the event occurred.
+
+   .. attribute:: delta
+
+      The amount the mouse wheel was rotated (for ``MouseWheel`` events).
+
+   .. attribute:: user_data
+
+      The data string of a virtual event, as passed to the *data* option of

+      It is ``'??'`` for non-virtual events.
+
+      .. versionadded:: 3.15
+
+   .. attribute:: detail
+
+      A fixed detail string for ``Enter``, ``Leave``, ``FocusIn``, ``FocusOut``
+      and ``ConfigureRequest`` events (see the Tcl/Tk documentation).
+      It is ``'??'`` for other events.
+
+      .. versionadded:: 3.15
+
+
+.. class:: EventType(*values)
+
+   An :class:`enum.StrEnum` enumerating the Tk event types, used as the value

+
+   .. versionadded:: 3.6
+
+
+
+.. class:: CallWrapper(func, subst, widget)
+
+   Internal helper that wraps a Python callback so that it can be invoked from
+   Tcl.
+   *func* is the Python function, *subst* is an optional function that
+   pre-processes the Tcl arguments, and *widget* is the widget used for error
+   reporting.
+   Instances are created automatically by :meth:`Misc.register`; this class is
+   not normally used directly.
+
+
+Module-level functions
+^^^^^^^^^^^^^^^^^^^^^^
+
+.. function:: Tcl(screenName=None, baseName=None, className='Tk', useTk=False)
+
+   The :func:`Tcl` function is a factory function which creates an object much
+   like that created by the :class:`Tk` class, except that it does not
+   initialize the Tk subsystem.
+   This is most often useful when driving the Tcl interpreter in an environment
+   where one doesn't want to create extraneous toplevel windows, or where one
+   cannot (such as Unix/Linux systems without an X server).
+   An object created by the :func:`Tcl` object can have a Toplevel window
+   created (and the Tk subsystem initialized) by calling its :meth:`~Tk.loadtk`
+   method.
+
+.. function:: NoDefaultRoot()
+
+   Inhibit the creation of an implicit default root window.
+   Afterwards :mod:`!tkinter` no longer creates a shared default root
+   automatically, and operations that rely on one --- such as constructing a
+   widget without an explicit *master* --- raise a :exc:`RuntimeError`.
+   Call this early in larger applications to make the root window explicit.
+
+.. function:: mainloop(n=0)
+
+   Run the Tk main event loop on the default root window until all windows are
+   destroyed.
+   Equivalent to calling :meth:`Misc.mainloop` on the default root.
+
+.. function:: getboolean(s)
+
+   Convert the Tcl boolean string *s* (one of ``'1'``, ``'true'``, ``'yes'``,
+   ``'on'`` and similar, or their false counterparts) to a Python
+   :class:`bool`.
+   Raise :exc:`TclError` for an invalid value.
+
+.. function:: getdouble(s)
+
+   Convert *s* to a floating-point number.
+   This is the built-in :class:`float`.
+
+.. function:: getint(s)
+
+   Convert *s* to an integer.
+   This is the built-in :class:`int`.
+
+.. function:: image_names()
+
+   Return the names of all existing images in the default root's interpreter.
+
+.. function:: image_types()
+
+   Return the available image types (such as ``'photo'`` and ``'bitmap'``) in
+   the default root's interpreter.
+
+
+.. _tkinter-file-handlers:
+
+File handlers
+^^^^^^^^^^^^^
+
+Tk allows you to register and unregister a callback function which will be
+called from the Tk mainloop when I/O is possible on a file descriptor.
+Only one handler may be registered per file descriptor. Example code::
+
+   import tkinter
+   widget = tkinter.Tk()
+   mask = tkinter.READABLE | tkinter.WRITABLE
+   widget.tk.createfilehandler(file, mask, callback)
+   ...
+   widget.tk.deletefilehandler(file)
+
+This feature is not available on Windows.
+
+Since you don't know how many bytes are available for reading, you may not
+want to use the :class:`~io.BufferedIOBase` or :class:`~io.TextIOBase`
+:meth:`~io.BufferedIOBase.read` or :meth:`~io.IOBase.readline` methods,
+since these will insist on reading a predefined number of bytes.

+------------------
+
+The following themed widgets complete the :mod:`tkinter.ttk` widget set.
+Each is the themed counterpart of the like-named classic :mod:`tkinter` widget
+and inherits the common methods of :class:`Widget`.
+
+.. class:: Button(master=None, **kw)
+
+   Ttk :class:`Button` widget, displays a textual label and/or image, and

+   toggled on and off.
+   It is the themed counterpart of :class:`tkinter.Checkbutton` and inherits
+   the common widget methods from :class:`Widget`.
+
+   .. method:: invoke()
+
+      Toggle the button between its selected and deselected states, invoke the
+      command associated with the button, and return its result.
+
+
+.. class:: Entry(master=None, widget=None, **kw)
+
+   Ttk :class:`Entry` widget, displays a one-line text string and allows the
+   user to edit it.
+   It is the themed counterpart of :class:`tkinter.Entry` and inherits the
+   common widget methods from :class:`Widget` as well as the editing methods
+   from :class:`tkinter.Entry`.
+
+   .. method:: bbox(index)
+
+      Return a tuple ``(x, y, width, height)`` giving the bounding box of the
+      character at the given *index*.
+
+      This shadows the inherited :meth:`!Misc.bbox`;
+      use :meth:`~tkinter.Misc.grid_bbox` for the grid bounding box.
+
+   .. method:: identify(x, y)
+
+      Return the name of the element under the point given by *x* and *y*, or
+      the empty string if no element is present at that location.
+
+   .. method:: validate()
+
+      Force validation of the entry and return ``True`` if validation
+      succeeded, and ``False`` otherwise.

+   label around its contents.
+   It is the themed counterpart of :class:`tkinter.LabelFrame` and inherits the
+   common widget methods from :class:`Widget`.
+
+
+.. class:: Menubutton(master=None, **kw)
+
+   Ttk :class:`Menubutton` widget, displays a textual label and/or image, and
+   pops up a menu when pressed.
+   It is the themed counterpart of :class:`tkinter.Menubutton` and inherits the
+   common widget methods from :class:`Widget`.
+
+
+.. class:: OptionMenu(master, variable, default=None, *values, **kwargs)
+
+   Ttk :class:`OptionMenu` widget, a :class:`Menubutton` that pops up a menu of
+   mutually exclusive choices.
+   *variable* is the variable that tracks the currently selected value,
+   *default* is the value to set initially, and *values* are the entries to
+   display in the menu.
+   A *command* keyword argument may be given to specify a callable that is
+   invoked with the selected value whenever the selection changes; the *style*
+   keyword argument sets the style used by the underlying menubutton; and the
+   *name* keyword argument sets the Tk widget name.
+
+   .. method:: set_menu(default=None, *values)
+
+      Replace the entries of the menu with *values*.
+      If *default* is given, also set it as the current value of the

+
+   .. method:: insert(pos, child, **kw)
+
+      Insert a pane containing *child* at the position *pos*.
+      *pos* is either the string ``'end'``, an integer index, or the name of a
+      managed subwindow.
+      If *child* is already managed by the paned window, move it to the
+      specified position.
+      Any keyword arguments set pane options.
+
+   .. method:: forget(child)
+
+      Remove *child*, which may be either an integer index or the name of a
+      managed subwindow, from the panes.
+
+      This shadows the inherited geometry-manager :meth:`!forget`;
+      use :meth:`~tkinter.Pack.pack_forget`, :meth:`~tkinter.Grid.grid_forget`
+      or :meth:`~tkinter.Place.place_forget` to remove the widget itself from
+      its manager.
+
+   .. method:: pane(pane, option=None, **kw)
+
+      Query or modify the options of the specified *pane*, where *pane* is
+      either an integer index or the name of a managed subwindow.
+      If no arguments are given, return a dictionary of the pane option values.
+      If *option* is specified, return the value of that option.
+      Otherwise, set the options given as keyword arguments to their
+      corresponding values.
+
+   .. method:: sashpos(index, newpos=None)
+
+      If *newpos* is specified, set the position of sash number *index* and
+      return its new position.
+      This may adjust the positions of adjacent sashes to ensure that positions
+      are monotonically increasing; positions are also constrained to be
+      between 0 and the total size of the widget.
+      If *newpos* is omitted, return the current position of the sash.
+
+
+.. class:: Radiobutton(master=None, **kw)
+
+   Ttk :class:`Radiobutton` widget, used as part of a group to control a single
+   shared variable by selecting one of several mutually exclusive values.
+   It is the themed counterpart of :class:`tkinter.Radiobutton` and inherits
+   the common widget methods from :class:`Widget`.
+
+   .. method:: invoke()
+
+      Set the option variable to the button's value, select the button, invoke
+      the command associated with the button, and return its result.
+
+
+.. class:: Scale(master=None, **kw)
+
+   Ttk :class:`Scale` widget, displays a slider that lets the user select a
+   numeric value from a range by moving the slider along a trough.
+   It is the themed counterpart of :class:`tkinter.Scale` and inherits the
+   common widget methods from :class:`Widget`.
+
+   .. method:: configure(cnf=None, **kw)
+
+      Modify or query the widget options, like
+      :meth:`Widget.configure <tkinter.Misc.configure>`.
+      In addition, this method clips the ``from`` and ``to`` values so that the
+      current value stays within the range defined by them.
+
+      .. versionchanged:: 3.9
+         Now returns the configuration value, like
+         :meth:`Widget.configure <tkinter.Misc.configure>`.
+
+
+   .. method:: get(x=None, y=None)
+
+      Return the current value of the scale.
+      If *x* and *y* are given, return the value corresponding to the pixel
+      coordinate *x*, *y* instead.
+
+
+.. class:: Scrollbar(master=None, **kw)
+
+   Ttk :class:`Scrollbar` widget, controls the viewport of an associated
+   scrollable widget such as a :class:`Treeview`, :class:`Entry` or
+   :class:`tkinter.Text`.
+   It is the themed counterpart of :class:`tkinter.Scrollbar` and inherits the
+   common widget methods from :class:`Widget`, as well as the :meth:`!set` and
+   :meth:`!get` methods from :class:`tkinter.Scrollbar`.

+
+.. class:: Separator(master=None, **kw)
+
+   Ttk :class:`Separator` widget, displays a horizontal or vertical separator
+   line.
+   It has no direct counterpart in :mod:`tkinter` and inherits the common
+   widget methods from :class:`Widget`.
+
+
+.. class:: Sizegrip(master=None, **kw)
+
+   Ttk :class:`Sizegrip` widget, displays a grip that allows the user to resize
+   the containing toplevel window by pressing and dragging the grip, typically
+   placed in the bottom-right corner.
+   It has no direct counterpart in :mod:`tkinter` and inherits the common
+   widget methods from :class:`Widget`.
+
+
+.. class:: LabeledScale(master=None, variable=None, from_=0, to=10, **kw)
+
+   A :class:`Frame` containing a :class:`Scale` and a :class:`Label` that shows
+   the scale's current value.
+   *variable* is the :class:`~tkinter.IntVar` tracked by the scale (one is
+   created if it is not given), and *from_* and *to* define the range of the
+   scale.
+
+   .. method:: destroy()
+
+      Destroy this widget and remove the trace callback registered on the
+      associated variable.
+
+
+.. class:: LabelFrame(master=None, **kw)
+
+   Alias of :class:`Labelframe`, kept for naming compatibility with
+   :class:`tkinter.LabelFrame`.
+
+
+.. class:: PanedWindow(master=None, **kw)
+
+   Alias of :class:`Panedwindow`, kept for naming compatibility with

+
+   If *removed* is provided, it must be a sequence of :class:`ZipInfo` objects
+   representing the recently removed members, and only their corresponding
+   local file entries will be removed.  Otherwise, the archive is scanned to
+   locate and remove local file entries that are no longer referenced in the
+   central directory.
+
+   Passing *removed* is the most reliable way to reclaim space: the
+   corresponding local file entries are located directly from the central
+   directory and removed regardless of how they were written, whereas the scan
+   used when *removed* is omitted may leave some entries in place (see
+   *strict_descriptor* below).  To remove members and reclaim their space in a
+   single step::
+
+      with ZipFile('spam.zip', 'a') as myzip:
+          removed = [myzip.remove(name) for name in ('ham.txt', 'eggs.txt')]
+          myzip.repack(removed)
+
+   When scanning, *strict_descriptor* controls how entries written with an
+   unsigned *data descriptor* are handled.  A data descriptor is an optional
+   record holding an entry's CRC and sizes, stored just after the entry's data;
+   it is used when the archive is written to a non-seekable stream, and is
+   *signed* when it begins with a marker signature or *unsigned* otherwise.
+   Unsigned descriptors have been deprecated by the `PKZIP Application Note`_
+   since version 6.3.0 (released in 2006) and are written only by some legacy
+   tools; signed descriptors—written by Python and other modern tools—are always
+   detected.  When *strict_descriptor* is true (the default), only signed data
+   descriptors are detected, so an unreferenced entry written with an unsigned
+   descriptor is not located and its space is not reclaimed by the scan.
+   Setting ``strict_descriptor=False`` additionally detects unsigned
+   descriptors, at the cost of a significantly slower scan—around 100 to 1000
+   times in the worst case—which may be exploitable as a denial-of-service
+   vector on untrusted input.  This does not affect entries without a data
+   descriptor, and is not needed when *removed* is provided.
+
+   *chunk_size* may be specified to control the buffer size when moving
+   entry data (default is 1 MiB).
+
+   Calling :meth:`repack` on a closed ZipFile will raise a :exc:`ValueError`.
+
+   .. note::
+      The scanning algorithm is heuristic-based and assumes that the ZIP file
+      is normally structured—for example, with local file entries stored
+      consecutively, without overlap or interleaved binary data.  Prepended
+      binary data, such as a self-extractor stub, is recognized and preserved
+      unless it happens to contain bytes that coincidentally resemble a valid
+      local file entry in multiple respects—an extremely rare case. Embedded
+      ZIP payloads are also handled correctly, as long as they follow normal
+      structure.  However, the algorithm does not guarantee correctness or

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
 All literals correspond to immutable data types, and hence the object's identity
 is less important than its value.  Multiple evaluations of literals with the
 same value (either the same occurrence in the program text or a different
 occurrence) may obtain the same object or a different object with the same
 value.
 
+.. admonition:: CPython implementation detail
+
+   For example, in CPython, *small* integers with the same value evaluate
+   to the same object::
+
+      >>> x = 7
+      >>> y = 7
+      >>> x is y
+      True
+
+   However, large integers evaluate to different objects::

+      >>> x = 123456789
+      >>> y = 123456789
+      >>> x is y
+      False
+
+   This behavior may change in future versions of CPython.
+   In particular, the boundary between "small" and "large" integers has
+   already changed in the past.
+
+   CPython will emit a :py:exc:`SyntaxWarning` when you compare literals

+Comprehensions
+--------------
+
+List, set and dictionary :dfn:`comprehensions` are a form of
+:ref:`container displays <displays>` where items are computed via a set of
+looping and filtering instructions rather than listed explicitly.
+
+In its simplest form, a comprehension consists of a single expression
+followed by a :keyword:`!for` clause.
+The :keyword:`!for` clause has the same syntax as the header of a
+:ref:`for statement <for>`, without a trailing colon.
+
+For example, a list of the first ten squares is::
 
-.. index:: pair: immutable; object
-           hashable
+   >>> [x**2 for x in range(10)]
+   [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
 
-Restrictions on the types of the key values are listed earlier in section
-:ref:`types`.  (To summarize, the key type should be :term:`hashable`, which excludes
-all mutable objects.)  Clashes between duplicate keys are not detected; the last
-value (textually rightmost in the display) stored for a given key value
-prevails.
+At run time, a list comprehension creates a new list.
+The expression after :keyword:`!in` must evaluate to an :term:`iterable`.
+For each element of this iterable, the element is bound to the :keyword:`!for`
+clause's target as in a :keyword:`!for` statement, then the expression
+before :keyword:`!for` is evaluated with the target in scope and the result
+is added to the new list.
+Thus, the example above is roughly equivalent to defining and calling
+the following function::
+
+   def make_list_of_squares(iterable):
+       result = []
+       for x in iterable:
+           result.append(x**2)
+       return result
+
+   make_list_of_squares(range(10))
+
+Set comprehensions work similarly.
+For example, here is a set of lowercase letters::
+
+   >>> {x.lower() for x in ['a', 'A', 'b', 'C']}
+   {'c', 'a', 'b'}
+
+At run time, this corresponds roughly to calling this function::
+
+   def make_lowercase_set(iterable):
+       result = set(iterable)
+       for x in iterable:
+           result.append(x.lower())
+       return result
+
+   make_lowercase_set(['a', 'A', 'b', 'C'])
+
+Dictionary comprehensions start with a colon-separated key-value pair instead
+of an expression. For example::
+
+   >>> {func.__name__: func for func in [print, hex, any]}
+   {'print': <built-in function print>,
+    'hex': <built-in function hex>,
+    'any': <built-in function any>}
+
+At run time, this corresponds roughly to::
+
+   def make_dict_mapping_names_to_functions(iterable):
+       result = {}
+       for func in iterable:
+           result[func.__name__] = func
+       return result
+
+   iterable([print, hex, any])
+
+As in other kinds of dictionary displays, the same key may be specified
+multiple times.
+Earlier values are overwritten by ones that are evaluated later.
+
+There are no *tuple comprehensions*.
+A similar syntax is instead used for :ref:`generator expressions <genexpr>`,
+from which you can construct a tuple like this::
+
+   >>> tuple(x**2 for x in range(10))
+   (0, 1, 4, 9, 16, 25, 36, 49, 64, 81)

+Filtering in comprehensions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The :keyword:`!for` clause may be followed by an :keyword:`!if` clause
+with an expression.
+
+For example, a list of names from the :mod:`math` module
+that start with ``f`` is::
+
+   >>> [name for name in vars(math) if name.startswith('f')]
+   ['fabs', 'factorial', 'floor', 'fma', 'fmod', 'frexp', 'fsum']
+
+At run time, the expression after :keyword:`!if` is evaluated before
+each element is added to the resulting container, and if it is false,
+the element is skipped.
+Thus, the above example roughly corresponds to defining and calling the
+following function::
+
+   def get_math_f_names(iterable):
+       result = []
+       for name in iterable:

+Complex comprehensions
+^^^^^^^^^^^^^^^^^^^^^^
+
+Generally, a comprehension's initial :keyword:`!for` clause may be followed by
+zero or more additional :keyword:`!for` or :keyword:`!if` clauses.
+For example, here is a list of names exposed by two Python modules,
+filtered to only include names that start with ``a``::
+
+   >>> import array
+   >>> import math
+   >>> [
+   ...     name
+   ...     for module in [array, math]

+                   result.append(name)
+       return result
+
+   get_a_names([array, math])
+
+The elements of the new container are those that would be produced by
+considering each of the :keyword:`!for` or :keyword:`!if` clauses a block,
+nesting from left to right, and evaluating the expression to produce an
+element (or dictionary entry) each time the innermost block is reached.
+
+Aside from the iterable expression in the leftmost :keyword:`!for` clause,
+the comprehension is executed in a separate implicitly nested scope.
+This ensures that names assigned to in the target list don't "leak" into
+the enclosing scope.
+For example::
+
+   >>> x = 'old value'
+   >>> [x**2 for x in range(10)]  # this `x` is local to the comprehension
+   >>> x
+   'old value'
+
+The iterable expression in the leftmost :keyword:`!for` clause is evaluated

+
+Subsequent :keyword:`!for` clauses and any filter condition in the
+leftmost :keyword:`!for` clause cannot be evaluated in the enclosing scope as
+they may depend on the values obtained from the leftmost iterable.
+
+To ensure the comprehension always results in a container of the appropriate
+type, ``yield`` and ``yield from`` expressions are prohibited in the implicitly

-When an object is subscripted, the interpreter will evaluate the primary and
-the expression list.
+In the subscription syntax, the object being subscribed -- a
+:ref:`primary <primaries>` -- is followed by a :dfn:`subscript` in
+square brackets.
+In the simplest case, the subscript is a single expression.
+
+Depending on the type of the object being subscribed, the subscript is
+sometimes called a :term:`key` (for mappings), :term:`index` (for sequences),
+or *type argument* (for :term:`generic types <generic type>`).
+Syntactically, these are all equivalent::
+
+   >>> colors = ['red', 'blue', 'green', 'black']
+   >>> colors[3]  # Subscripting a list using the index 3
+   'black'
+
+   >>> list[str]  # Parameterizing the list type using the type argument str
+   list[str]
+
+At runtime, the interpreter will evaluate the primary and
+the subscript, and call the primary's :meth:`~object.__getitem__` or
+:meth:`~object.__class_getitem__` :term:`special method` with the subscript
+as argument.
+For more details on which of these methods is called, see
+:ref:`classgetitem-versus-getitem`.
+
+To show how subscription works, we can define a custom object that
+implements :meth:`~object.__getitem__` and prints out the value of
+the subscript::
+
+   >>> class SubscriptionDemo:
+   ...     def __getitem__(self, key):
+   ...         print(f'subscripted with: {key!r}')
+   ...
+   >>> demo = SubscriptionDemo()
+   >>> demo[1]
+   subscripted with: 1
+   >>> demo['a' * 3]
+   subscripted with: 'aaa'
 
-The primary must evaluate to an object that supports subscription. An object
-may support subscription through defining one or both of
-:meth:`~object.__getitem__` and :meth:`~object.__class_getitem__`. When the
-primary is subscripted, the evaluated result of the expression list will be
-passed to one of these methods. For more details on when ``__class_getitem__``
-is called instead of ``__getitem__``, see :ref:`classgetitem-versus-getitem`.
+See :meth:`~object.__getitem__` documentation for how built-in types handle
+subscription.
 
-If the expression list contains at least one comma, or if any of the expressions
-are starred, the expression list will evaluate to a :class:`tuple` containing
-the items of the expression list. Otherwise, the expression list will evaluate
-to the value of the list's sole member.
+Subscriptions may also be used as targets in :ref:`assignment <assignment>` or
+:ref:`deletion <del>` statements.
+In these cases, the interpreter will call the subscripted object's
+:meth:`~object.__setitem__` or :meth:`~object.__delitem__`
+:term:`special method`, respectively, instead of :meth:`~object.__getitem__`.

-For built-in objects, there are two types of objects that support subscription
-via :meth:`~object.__getitem__`:
-
-1. Mappings. If the primary is a :term:`mapping`, the expression list must
-   evaluate to an object whose value is one of the keys of the mapping, and the
-   subscription selects the value in the mapping that corresponds to that key.
-   An example of a builtin mapping class is the :class:`dict` class.
-2. Sequences. If the primary is a :term:`sequence`, the expression list must
-   evaluate to an :class:`int` or a :class:`slice` (as discussed in the
-   following section). Examples of builtin sequence classes include the
-   :class:`str`, :class:`list` and :class:`tuple` classes.
-
-The formal syntax makes no special provision for negative indices in
-:term:`sequences <sequence>`. However, built-in sequences all provide a :meth:`~object.__getitem__`
-method that interprets negative indices by adding the length of the sequence
-to the index so that, for example, ``x[-1]`` selects the last item of ``x``. The
-resulting value must be a nonnegative integer less than the number of items in
-the sequence, and the subscription selects the item whose index is that value
-(counting from zero). Since the support for negative indices and slicing
-occurs in the object's :meth:`~object.__getitem__` method, subclasses overriding
-this method will need to explicitly add that support.

+Slicings
+^^^^^^^^
 
-.. index::
-   single: start (slice object attribute)
-   single: stop (slice object attribute)
-   single: step (slice object attribute)
-
-The semantics for a slicing are as follows.  The primary is indexed (using the
-same :meth:`~object.__getitem__` method as
-normal subscription) with a key that is constructed from the slice list, as
-follows.  If the slice list contains at least one comma, the key is a tuple
-containing the conversion of the slice items; otherwise, the conversion of the
-lone slice item is the key.  The conversion of a slice item that is an
-expression is that expression.  The conversion of a proper slice is a slice
-object (see section :ref:`types`) whose :attr:`~slice.start`,
-:attr:`~slice.stop` and :attr:`~slice.step` attributes are the values of the
-expressions given as lower bound, upper bound and stride, respectively,
-substituting ``None`` for missing expressions.
+A more advanced form of subscription, :dfn:`slicing`, is commonly used
+to extract a portion of a :ref:`sequence <datamodel-sequences>`.
+In this form, the subscript is a :term:`slice`: up to three
+expressions separated by colons.
+Any of the expressions may be omitted, but a slice must contain at least one
+colon::
+
+   >>> number_names = ['zero', 'one', 'two', 'three', 'four', 'five']
+   >>> number_names[1:3]
+   ['one', 'two']
+   >>> number_names[1:]
+   ['one', 'two', 'three', 'four', 'five']

+   >>> number_names[:-3]
+   ['zero', 'one', 'two']
+   >>> del number_names[4:]
+   >>> number_names
+   ['zero', 'one', 'two', 'three']
+
+When a slice is evaluated, the interpreter constructs a :class:`slice` object
+whose :attr:`~slice.start`, :attr:`~slice.stop` and
+:attr:`~slice.step` attributes, respectively, are the results of the
+expressions between the colons.
+Any missing expression evaluates to :const:`None`.
+This :class:`!slice` object is then passed to the :meth:`~object.__getitem__`
+or :meth:`~object.__class_getitem__` :term:`special method`, as above. ::

+   subscripted with: (slice(1, 2, None), 3)
+
+This form is commonly used with numerical libraries for slicing
+multi-dimensional data.
+In this case, the interpreter constructs a :class:`tuple` of the results of the
+expressions or slices, and passes this tuple to the :meth:`~object.__getitem__`
+or :meth:`~object.__class_getitem__` :term:`special method`, as above.

+Non-ASCII characters in names
+-----------------------------
+
+Names that contain non-ASCII characters need additional normalization
+and validation beyond the rules and grammar explained
+:ref:`above <identifiers>`.
+For example, ``ř_1``, ``蛇``, or ``साँप``  are valid names, but ``r〰2``,
+``€``, or ``🐍`` are not.
+
+This section explains the exact rules.
+
+All names are converted into the `normalization form`_ NFKC while parsing.
+This means that, for example, some typographic variants of characters are
+converted to their "basic" form. For example, ``fiⁿₐˡᵢᶻₐᵗᵢᵒₙ`` normalizes to
+``finalization``, so Python treats them as the same name::
+
+   >>> fiⁿₐˡᵢᶻₐᵗᵢᵒₙ = 3
+   >>> finalization
+   3
+
+.. note::
+
+   Normalization is done at the lexical level only.
+   Run-time functions that take names as *strings* generally do not normalize
+   their arguments.
+   For example, the variable defined above is accessible at run time in the
+   :func:`globals` dictionary as ``globals()["finalization"]`` but not
+   ``globals()["fiⁿₐˡᵢᶻₐᵗᵢᵒₙ"]``.
+
+Similarly to how ASCII-only names must contain only letters, digits and
+the underscore, and cannot start with a digit, a valid name must
+start with a character in the "letter-like" set ``xid_start``,
+and the remaining characters must be in the "letter- and digit-like" set
+``xid_continue``.
+
+These sets are based on the *XID_Start* and *XID_Continue* sets as defined by the
+Unicode standard annex `UAX-31`_.
+Python's ``xid_start`` additionally includes the underscore (``_``).
+Note that Python does not necessarily conform to `UAX-31`_.
+
+A non-normative listing of characters in the *XID_Start* and *XID_Continue*
+sets as defined by Unicode is available in the `DerivedCoreProperties.txt`_
+file in the Unicode Character Database.
+For reference, the construction rules for the ``xid_*`` sets are given below.
+
+The set ``id_start`` is defined as the union of:
+
+* Unicode category ``<Lu>`` - uppercase letters (includes ``A`` to ``Z``)
+* Unicode category ``<Ll>`` - lowercase letters (includes ``a`` to ``z``)
+* Unicode category ``<Lt>`` - titlecase letters
+* Unicode category ``<Lm>`` - modifier letters
+* Unicode category ``<Lo>`` - other letters
+* Unicode category ``<Nl>`` - letter numbers
+* {``"_"``} - the underscore
+* ``<Other_ID_Start>`` - an explicit set of characters in `PropList.txt`_
+  to support backwards compatibility
+
+The set ``xid_start`` then closes this set under NFKC normalization, by
+removing all characters whose normalization is not of the form
+``id_start id_continue*``.
+
+The set ``id_continue`` is defined as the union of:
+
+* ``id_start`` (see above)
+* Unicode category ``<Nd>`` - decimal numbers (includes ``0`` to ``9``)
+* Unicode category ``<Pc>`` - connector punctuations

+expressions in the replacement field.
+The exact way the work is split is a CPython implementation detail.
+
+Correspondingly, the f-string grammar is a mix of
+:ref:`lexical and syntactic definitions <notation-lexical-vs-syntactic>`.
+
+Whitespace is significant in these situations:
+
+* There may be no whitespace in :py:data:`~token.FSTRING_START` (between
+  the prefix and quote).
+* Whitespace in :py:data:`~token.FSTRING_MIDDLE` is part of the literal
+  string contents.
+* In ``fstring_replacement_field``, if ``f_debug_specifier`` is present,
+  all whitespace after the opening brace until the ``f_debug_specifier``,
+  as well as whitespace immediately following ``f_debug_specifier``,
+  is retained as part of the expression.
+
+  .. impl-detail::
+
+     The expression is not handled in the tokenization phase; it is
+     retrieved from the source code using locations of the ``{`` token
+     and the token after ``=``.
+
+
+The ``FSTRING_MIDDLE`` definition uses
+:ref:`negative lookaheads <lexical-lookaheads>` (``!``)
+to indicate special characters (backslash, newline, ``{``, ``}``) and
+sequences (``f_quote``).

+
+The :keyword:`lazy` keyword is a :ref:`soft keyword <soft-keywords>` that
+only has special meaning when it appears immediately before an
+:keyword:`import` or :keyword:`from` statement. When an import statement is
+preceded by the :keyword:`lazy` keyword, the import becomes *lazy*: the
+module is not loaded immediately at the import statement. Instead, a lazy
+proxy object is created and bound to the name. The actual module is loaded
+on first use of that name.
+
+Lazy imports are only permitted at module scope. Using :keyword:`lazy`
+inside a function, class body, or
+:keyword:`try`/:keyword:`except`/:keyword:`finally` block raises a
+:exc:`SyntaxError`. Star imports cannot be lazy (``lazy from module import
+*`` is a syntax error), and :ref:`future statements <future>` cannot be
+lazy.
+
+When using ``lazy from ... import``, each imported name is bound to a lazy
+proxy object. The first access to any of these names triggers loading of the
+entire module and resolves only that specific name to its actual value.
+Other names remain as lazy proxies until they are accessed.
+
+Example::
+
+   lazy import json
+   import sys
+
+   print('json' in sys.modules)  # False - json module not yet loaded
+
+   # First use triggers loading
+   result = json.dumps({"hello": "world"})
+
+   print('json' in sys.modules)  # True - now loaded
+
+If an error occurs during module loading (such as :exc:`ImportError` or
+:exc:`SyntaxError`), it is raised at the point where the lazy import is first
+used, not at the import statement itself.
+
+See :pep:`810` for the full specification of lazy imports.

+   single: __lazy_modules__
+
+As an alternative to using the :keyword:`lazy` keyword, a module can opt
+into lazy loading for specific imports by defining a module-level
+:attr:`~module.__lazy_modules__` variable.  When present, it must be a
+container of fully qualified module name strings.  Any regular (non-``lazy``)
+:keyword:`import` statement at module scope whose target appears in
+:attr:`!__lazy_modules__` is treated as a lazy import, exactly as if the
+:keyword:`lazy` keyword had been used.
+
+This provides a way to enable lazy loading for specific dependencies without
+changing individual ``import`` statements. This is useful when supporting
+Python versions older than 3.15 while using lazy imports in 3.15+::
+
+   __lazy_modules__ = ["json", "pathlib"]
+
+   import json     # loaded lazily (name is in __lazy_modules__)
+   import os       # loaded eagerly (name not in __lazy_modules__)
+
+   import pathlib  # loaded lazily
+
+Relative imports are resolved to their absolute name before the lookup, so
+:attr:`!__lazy_modules__` must always contain fully qualified module names.
+
+For ``from``-style imports, the relevant name is the module following
+``from``, not the names of its members::
+
+   # In mypackage/mymodule.py
+   __lazy_modules__ = ["mypackage", "mypackage.sub.utils"]
+
+   from . import helper         # loaded lazily: . resolves to mypackage
+   from .sub.utils import func  # loaded lazily: .sub.utils resolves to mypackage.sub.utils
+   import json                  # loaded eagerly (not in __lazy_modules__)
+
+Imports inside functions, class bodies, or
+:keyword:`try`/:keyword:`except`/:keyword:`finally` blocks are always eager,
+regardless of :attr:`!__lazy_modules__`.

+Unpacking in Lists and List Comprehensions
+------------------------------------------
+
+The section on :ref:`tut-unpacking-arguments` describes the use of ``*`` to
+"unpack" the elements of an iterable object, providing each one separately as
+an argument to a function.  Unpacking can also be used in other contexts, for
+example, when creating lists.  When specifying elements of a list, prefixing an
+expression by a ``*`` will unpack the result of that expression, adding each of
+its elements to the list we're creating::
+
+   >>> x = [1, 2, 3]
+   >>> [0, *x, 4, 5, 6]
+   [0, 1, 2, 3, 4, 5, 6]
+
+This only works if the expression following the ``*`` evaluates to an iterable
+object; trying to unpack a non-iterable object will raise an exception::
+
+   >>> x = 1
+   >>> [0, *x, 2, 3, 4]
+   Traceback (most recent call last):
+     File "<python-input-1>", line 1, in <module>
+       [0, *x, 2, 3, 4]
+   TypeError: Value after * must be an iterable, not int
+
+Unpacking can also be used in list comprehensions, as a way to build a new list
+representing the concatenation of an arbitrary number of iterables::
+
+   >>> x = [[1, 2, 3], [4, 5, 6], [], [7], [8, 9]]
+   >>> [*element for element in x]
+   [1, 2, 3, 4, 5, 6, 7, 8, 9]
+
+Note that the effect is that each element from ``x`` is unpacked.  This works
+for arbitrary iterable objects, not just lists::
+
+   >>> x = [[1, 2, 3], 'cat', {'spam': 'eggs'}]
+   >>> [*element for element in x]
+   [1, 2, 3, 'c', 'a', 't', 'spam']

+Index signatures
+----------------
+
+.. versionadded:: 26.2
+
+Index files may be signed to detect tampering. A signature is a catalog file
+at the same URL as the index with ``.cat`` added to the filename. The catalog
+file should contain the hash of its matching index file, and should be signed
+with a valid Authenticode signature. This allows standard tooling (on Windows)
+to generate a signature, and any certificate may be used as long as the client
+operating system already trusts its certification authority (root CA).
+
+Index signatures are only downloaded and checked when the local configuration's
+``source_settings`` section includes the index URL and ``requires_signature`` is
+true, or the index JSON contains ``requires_signature`` set to true. When the
+setting exists in local configuration, even when false, settings in the index
+are ignored.
+
+As well as requiring a valid signature, the ``required_root_subject`` and
+``required_publisher_subject`` settings can further restrict acceptable
+signatures based on the certificate Subject fields. Any attribute specified in
+the configuration must match the attribute in the certificate (additional
+attributes in the certificate are ignored). Typical attributes are ``CN=`` for
+the common name, ``O=`` for the organizational unit, and ``C=`` for the
+publisher's country.
+
+Finally, the ``required_publisher_eku`` setting allows requiring that a specific
+Enhanced Key Usage (EKU) has been assigned to the publisher certificate. For
+example, the EKU ``1.3.6.1.5.5.7.3.3`` indicates that the certificate was
+intended for code signing (as opposed to server or client authentication).
+In combination with a specific root CA, this provides another mechanism to
+verify a legitimate signature.
+
+This is an example ``source_settings`` section from a configuration file. In
+this case, the publisher of the feed is uniquely identified by the combination
+of the Microsoft Identity Verification root and the EKU assigned by that root.
+The signature for this case would be found at
+``https://www.python.org/ftp/python/index-windows.json.cat``.
+
+.. code:: json5
+
+   {
+     "source_settings": {
+       "https://www.python.org/ftp/python/index-windows.json": {

+       }
+     }
+   }
+
+The same settings could be specified in the ``index.json`` file instead. In this
+case, the root and EKU are omitted, meaning that the signature must be valid and
+have a specific common name in the publisher's certificate, but no other checks
+are used.
+

+     "required_publisher_subject": "CN=Python Software Foundation",
+     "versions": [
+       // ...
+     ]
+   }
+
+When settings from inside a feed are used, the user is notified and the settings
+are shown in the log file or verbose output. It is recommended to copy these
+settings into a local configuration file for feeds that will be used frequently,
+so that unauthorised modifications to the feed cannot disable verification.
+
+It is not possible to override the location of the signature file in the feed or
+through a configuration file. Administrators can provide their own
+``source_settings`` in a mandatory configuration file (see
+:ref:`pymanager-admin-config`).
+
+If signature validation fails, you will be notified and prompted to continue.
+When interactive confirmation is not allowed (for example, because ``--yes`` was
+specified), it will always abort. To use a feed with invalid configuration in
+this scenario, you must provide a configuration file that disables signature
+checking for that feed.

 New features
 ============
 
+.. _whatsnew315-lazy-imports:
+
+:pep:`810`: Explicit lazy imports
+---------------------------------
+
+Large Python applications often suffer from slow startup times. A
+significant contributor to this problem is the import system: when a module
+is imported, Python must locate the file, read it from disk, compile it to
+bytecode, and execute all top-level code. For applications with deep
+dependency trees, this process can take seconds, even when most of the
+imported code is never actually used during a particular run.
+
+Developers have worked around this by moving imports inside functions, using
+:mod:`importlib` to load modules on demand, or restructuring code to avoid
+unnecessary dependencies. These approaches work but make code harder to read
+and maintain, scatter import statements throughout the codebase, and require
+discipline to apply consistently.
+
+Python now provides a cleaner solution through explicit :keyword:`lazy`
+imports using the new ``lazy`` soft keyword. When you mark an import as
+lazy, Python defers the actual module loading until the imported name is
+first used. This gives you the organizational benefits of declaring all
+imports at the top of the file while only paying the loading cost for
+modules you actually use.
+
+The ``lazy`` keyword works with both ``import`` and ``from ... import``
+statements. When you write ``lazy import heavy_module``, Python does not
+immediately load the module. Instead, it creates a lightweight proxy object.
+The actual module loading happens transparently when you first access the
+name:
+
+.. code-block:: python
+
+   lazy import json
+   lazy from pathlib import Path
+
+   print("Starting up...")  # json and pathlib not loaded yet
+
+   data = json.loads('{"key": "value"}')  # json loads here
+   p = Path(".")  # pathlib loads here
+
+This mechanism is particularly useful for applications that import many
+modules at the top level but may only use a subset of them in any given run.
+The deferred loading reduces startup latency without requiring code
+restructuring or conditional imports scattered throughout the codebase.
+
+In the case where loading a lazily imported module fails (for example, if
+the module does not exist), Python raises the exception at the point of
+first use rather than at import time. The associated traceback includes both
+the location where the name was accessed and the original import statement,
+making it straightforward to diagnose and debug the failure.
+
+For cases where you want to enable lazy loading globally without modifying
+source code, Python provides the :option:`-X lazy_imports <-X>` command-line
+option and the :envvar:`PYTHON_LAZY_IMPORTS` environment variable. Both
+accept two values: ``all`` makes all imports lazy by default, and ``normal``
+(the default) respects the ``lazy`` keyword in source code. The
+:func:`sys.set_lazy_imports` and :func:`sys.get_lazy_imports` functions allow
+changing and querying this mode at runtime.
+
+For more selective control, :func:`sys.set_lazy_imports_filter` accepts a
+callable that determines whether a specific module should be loaded lazily.
+The filter receives three arguments: the importing module's name (or
+``None``), the imported module's name, and the fromlist (or ``None`` for
+regular imports). It should return ``True`` to allow the import to be lazy,
+or ``False`` to force eager loading. This allows patterns like making only
+your own application's modules lazy while keeping third-party dependencies
+eager:
+
+.. code-block:: python
+
+   import sys
+
+   def myapp_filter(importing, imported, fromlist):
+       return imported.startswith("myapp.")
+   sys.set_lazy_imports_filter(myapp_filter)
+   sys.set_lazy_imports("all")
+
+   import myapp.slow_module  # lazy (matches filter)
+   import json               # eager (does not match filter)
+
+The proxy type itself is available as :class:`types.LazyImportType` for code
+that needs to detect lazy imports programmatically.
+
+There are some restrictions on where the ``lazy`` keyword can be used. Lazy
+imports are only permitted at module scope; using ``lazy`` inside a
+function, class body, or ``try``/``except``/``finally`` block raises a
+:exc:`SyntaxError`. Neither star imports nor future imports can be lazy
+(``lazy from module import *`` and ``lazy from __future__ import ...`` both
+raise :exc:`SyntaxError`).
+
+For code that cannot use the ``lazy`` keyword directly (for example, when
+supporting Python versions older than 3.15 while still using lazy
+imports on 3.15+), a module can define
+:attr:`~module.__lazy_modules__` as a container of fully qualified module
+name strings.  Regular ``import`` statements for those modules are then treated
+as lazy, with the same semantics as the ``lazy`` keyword::
+
+   __lazy_modules__ = ["json", "pathlib"]
+
+   import json     # lazy
+   import os       # still eager
+
+.. seealso:: :pep:`810` for the full specification and rationale.

+
+
+.. _whatsnew315-frozendict:
+
+:pep:`814`: Add frozendict built-in type
+----------------------------------------
+
+A new :term:`immutable` type, :class:`frozendict`, is added to the :mod:`builtins` module.
+It does not allow modification after creation. A :class:`!frozendict` is not a subclass of ``dict``;
+it inherits directly from ``object``. A :class:`!frozendict` is :term:`hashable`
+as long as all of its keys and values are hashable. A :class:`!frozendict` preserves
+insertion order, but comparison does not take order into account.
+
+For example::
+
+    >>> a = frozendict(x=1, y=2)
+    >>> a
+    frozendict({'x': 1, 'y': 2})
+    >>> a['z'] = 3
+    Traceback (most recent call last):
+      File "<python-input-2>", line 1, in <module>
+        a['z'] = 3
+        ~^^^^^
+    TypeError: 'frozendict' object does not support item assignment
+    >>> b = frozendict(y=2, x=1)
+    >>> hash(a) == hash(b)
+    True
+    >>> a == b
+    True
+
+The following standard library modules have been updated to accept
+:class:`!frozendict`: :mod:`copy`, :mod:`decimal`, :mod:`json`, :mod:`marshal`,
+:mod:`plistlib` (only for serialization), :mod:`pickle`, :mod:`pprint` and
+:mod:`xml.etree.ElementTree`.
+
+:func:`eval` and :func:`exec` accept :class:`!frozendict` for *globals*, and
+:func:`type` and :meth:`str.maketrans` accept :class:`!frozendict` for *dict*.
+
+Code checking for :class:`dict` type using ``isinstance(arg, dict)`` can be
+updated to ``isinstance(arg, (dict, frozendict))`` to accept also the
+:class:`!frozendict` type, or to ``isinstance(arg, collections.abc.Mapping)``
+to accept also other mapping types such as :class:`~types.MappingProxyType`.
+
+.. seealso:: :pep:`814` for the full specification and rationale.

+
+
+.. _whatsnew315-sentinel:
+
+:pep:`661`: Add sentinel built-in type
+--------------------------------------
+
+A new :class:`sentinel` type is added to the :mod:`builtins` module for
+creating unique sentinel values with a concise representation.  Sentinel
+objects preserve identity when copied, support use in type expressions with
+the ``|`` operator, and can be pickled when they are importable by module and
+name.

+
+
+.. _whatsnew315-profiling-package:
+
+:pep:`799`: A dedicated profiling package
+-----------------------------------------
+
+A new :mod:`profiling` module has been added to organize Python's built-in
+profiling tools under a single, coherent namespace. This module contains:
+
+* :mod:`profiling.tracing`: deterministic function-call tracing (relocated from
+  ``cProfile``).
+* :mod:`profiling.sampling`: a new statistical sampling profiler (named Tachyon).
+
+The ``cProfile`` module remains as an alias for backwards compatibility.
+The :mod:`profile` module is deprecated and will be removed in Python 3.17.

+
+* **Multiple profiling modes**: Choose what to measure based on your performance investigation:
+
+  * **Wall-clock time** (``--mode wall``, default): Measures real elapsed time including I/O,

+  * **GIL-holding time** (``--mode gil``): Measures time spent holding Python's Global Interpreter
+    Lock. Use this to identify which threads dominate GIL usage in multi-threaded applications.
+  * **Exception handling time** (``--mode exception``): Captures samples only from threads with

+.. _whatsnew315-frame-pointers:
+
+:pep:`831`: Frame pointers enabled by default
+---------------------------------------------
+
+CPython is now built with frame pointers by default on platforms that support
+them.  This uses the compiler flags ``-fno-omit-frame-pointer`` and
+``-mno-omit-leaf-frame-pointer``, making native stack unwinding faster and
+more reliable for system profilers, debuggers, crash analysis tools, and
+eBPF-based observability tools.
 
-.. code-block:: shell
+The flags are exposed through :mod:`sysconfig`, so extension modules built by
+tools that consume Python's build configuration inherit frame pointers by
+default.  This propagation is intentional: mixed Python/native profiling needs
+an unbroken frame-pointer chain through the interpreter, extension modules,
+embedding applications, and native libraries.
 
-  python -m profiling.sampling --collapsed 1234
+.. important::
+
+   Third-party build backends and native build systems should preserve these
+   flags when they consume Python's :mod:`sysconfig` values.  Build systems
+   that compile C, C++, Rust, or other native code without inheriting Python's
+   compiler flags should enable equivalent frame-pointer flags themselves.  A
+   single native component built without frame pointers can break stack
+   unwinding for the whole Python process.

+
+
+.. _whatsnew315-unpacking-in-comprehensions:
+
+:pep:`798`: Unpacking in comprehensions
+---------------------------------------
+
+List, set, and dictionary comprehensions, as well as generator expressions, now
+support unpacking with ``*`` and ``**``.  This extends the unpacking syntax
+from :pep:`448` to comprehensions, providing a new syntax for combining an
+arbitrary number of iterables or dictionaries into a single flat structure.
+This new syntax is a direct alternative to nested comprehensions,
+:func:`itertools.chain`, and :meth:`itertools.chain.from_iterable`.  For
+example::
+
+    >>> lists = [[1, 2], [3, 4], [5]]
+    >>> [*L for L in lists]  # equivalent to [x for L in lists for x in L]
+    [1, 2, 3, 4, 5]
+
+    >>> sets = [{1, 2}, {2, 3}, {3, 4}]
+    >>> {*s for s in sets}  # equivalent to {x for s in sets for x in s}
+    {1, 2, 3, 4}
+
+    >>> dicts = [{'a': 1}, {'b': 2}, {'a': 3}]
+    >>> {**d for d in dicts}  # equivalent to {k: v for d in dicts for k,v in d.items()}
+    {'a': 3, 'b': 2}
+
+Generator expressions can similarly use unpacking to yield values from multiple
+iterables::
+
+    >>> gen = (*L for L in lists)  # equivalent to (x for L in lists for x in L)
+    >>> list(gen)
+    [1, 2, 3, 4, 5]
+
+This change also extends to asynchronous generator expressions, such that, for
+example, ``(*a async for a in agen())`` is equivalent to ``(x async for a in
+agen() for x in a)``.

+:pep:`829`: Package startup configuration files
+-----------------------------------------------
+
+Loaded by the :mod:`site` module when ``-S`` is not given, :ref:`.pth files <site-pth-files>`
+can contain lines that both extend :data:`sys.path` and execute arbitrary code
+when the line starts with ``import`` (followed by a space or tab).  The latter
+functionality can be problematic, since it is difficult to know exactly what
+gets executed when Python starts up.
 
-Profile all threads and sort by total time:
+As a step towards improving the ability to audit pre-start executable code,
+Python 3.15 introduces :ref:`.start files <site-start-files>` which contain entry point
+specifications of the form ``pkg.mod:callable`` where ``pkg.mod`` is the
+import path to the given callable.  When Python starts up, the callable is
+located and called with no arguments.

+:pep:`803` -- Stable ABI for free-threaded builds
+-------------------------------------------------
 
-  Summary of Interesting Functions:
+C extensions that target the :ref:`Stable ABI <stable-abi>` can now be
+compiled for the new *Stable ABI for Free-Threaded Builds* (also known
+as ``abi3t``), which makes them compatible with
+:term:`free-threaded builds <free-threaded build>` of CPython.
+This usually requires some non-trivial changes to the source code;
+specifically:
 
-  Functions with Highest Direct/Cumulative Ratio (Hot Spots):
-    1.000 direct/cumulative ratio, 33.3% direct samples: test_compile.py:(TestSpecifics.test_compiler_recursion_limit.<locals>.check_limit)
-    1.000 direct/cumulative ratio, 27.2% direct samples: ast.py:(parse)
-    1.000 direct/cumulative ratio, 3.6% direct samples: subprocess.py:(Popen._execute_child)
+- Switching to API introduced in :pep:`697` (Python 3.12), such as
+  negative :c:member:`~PyType_Spec.basicsize` and
+  :c:func:`PyObject_GetTypeData`, rather than making :c:type:`PyObject`
+  part of the instance struct; and
+- Switching from a ``PyInit_`` function to a new export hook,
+  :c:func:`PyModExport_* <PyModExport_modulename>`, introduced for this
+  purpose in :pep:`793`, with a new :c:type:`PySlot` structure
+  introduced in :pep:`820`.
 
-  Functions with Highest Call Frequency (Indirect Calls):
-    418815 indirect calls, 87.9% total stack presence: case.py:(TestCase.run)
-    415519 indirect calls, 87.9% total stack presence: case.py:(TestCase._callTestMethod)
-    159470 indirect calls, 33.5% total stack presence: test_compile.py:(TestSpecifics.test_compiler_recursion_limit)
+Note that Stable ABI does not offer all the functionality that CPython
+has to offer.
+Extensions that cannot switch to ``abi3t`` should continue to build for
+the existing Stable ABI (``abi3``) and the version-specific ABI for
+free-threading (``cp315t``) separately.
+
+Stable ABI for Free-Threaded Builds should typically
+be selected in a build tool (such as, for example, Setuptools, meson-python,
+scikit-build-core, or Maturin).
+At the time of writing, these tools did **not** support ``abi3t``.
+If this is the case for your tool, compile for ``cp315t`` separately.
+If not using a build tool -- or when writing such a tool -- you can select
+``abi3t`` by setting the macro :c:macro:`!Py_TARGET_ABI3T` as discussed
+in :ref:`abi3-compiling`.
 
-  Functions with Highest Call Magnification (Cumulative/Direct):
-    12267.9x call magnification, 159470 indirect calls from 13 direct: test_compile.py:(TestSpecifics.test_compiler_recursion_limit)
-    10581.7x call magnification, 116388 indirect calls from 11 direct: test_ast.py:(AST_Tests.test_ast_recursion_limit)
-    9740.9x call magnification, 418815 indirect calls from 43 direct: case.py:(TestCase.run)
+A practical :ref:`migration guide <abi3t-migration-howto>` for switching to
+``abi3t`` is available.
 
-The profiler automatically identifies performance bottlenecks through statistical
-analysis, highlighting functions with high CPU usage and call frequency patterns.

-(Contributed by Pablo Galindo and László Kiss Kollár in :gh:`135953`.)
+:pep:`788`: Protecting the C API from interpreter finalization
+--------------------------------------------------------------
+
+In the C API, :term:`interpreter finalization <interpreter shutdown>` can be
+problematic for many extensions, because :term:`attaching <attached thread
+state>` a thread state will permanently hang the thread, resulting in deadlocks
+and other spurious issues. Additionally, it has historically been impossible
+to safely check whether an interpreter is alive before using it, leading to crashes
+when a thread concurrently deletes an interpreter while another thread is
+trying to attach to it.
+
+There are now several new suites of APIs to circumvent these problems:
+
+* :ref:`Interpreter guards <interpreter-guards>`, which prevent an interpreter
+  from finalizing.
+* :ref:`Interpreter views <interpreter-views>`, which allow thread-safe access
+  to an interpreter that may be concurrently finalizing or deleted.
+* :ref:`New APIs <c-api-attach-detach>` to automatically attach and detach
+  thread states that come with built-in protection against finalization.
+
+In addition, APIs in the ``PyGILState`` family (most notably
+:c:func:`PyGILState_Ensure` and :c:func:`PyGILState_Release`) have been
+:term:`soft deprecated`. There is **no** plan to remove them, and existing
+code will continue to work, but there will be no new ``PyGILState`` APIs
+in future versions of Python.

+.. seealso:: :pep:`788` for further details.

+          },
+       }

+    and the ``\e`` escape for the escape character:
+
+    .. code-block:: toml
+
+       null = "null byte: \x00; letter a: \x61"

 types
-------
+-----
 
 * Expose the write-through :func:`locals` proxy type
-  as :data:`types.FrameLocalsProxyType`.
+  as :class:`types.FrameLocalsProxyType`.
   This represents the type of the :attr:`frame.f_locals` attribute,
   as described in :pep:`667`.
 
 
+typing
+------
+
+.. _whatsnew315-typeform:
+
+* :pep:`747`: Add :data:`~typing.TypeForm`, a new special form for annotating
+  values that are themselves type expressions.
+  ``TypeForm[T]`` means "a type form object describing ``T`` (or a type
+  assignable to ``T``)". At runtime, ``TypeForm(x)`` simply returns ``x``,
+  which allows explicit annotation of type-form values without changing
+  behavior.
+
+  This helps libraries that accept user-provided type expressions
+  (for example ``int``, ``str | None``, :class:`~typing.TypedDict`
+  classes, or ``list[int]``) expose precise signatures:
+
+  .. code-block:: python
+
+     from typing import Any, TypeForm
+
+     def cast[T](typ: TypeForm[T], value: Any) -> T: ...
+
+  (Contributed by Jelle Zijlstra in :gh:`145033`.)
+
+.. _whatsnew315-typeddict:
+
+* :pep:`728`: Add support in :class:`~typing.TypedDict` for the *closed*
+  and *extra_items* class arguments. A closed :class:`~typing.TypedDict`
+  does not allow extra keys beyond those specified in the class body, while
+  a :class:`~typing.TypedDict` with ``extra_items`` allows arbitrary extra
+  items where the values are of the specified type. (Contributed by Angela
+  Liss in :gh:`137840`.)
+
+* Code like ``class ExtraTypeVars(P1[S], Protocol[T, T2]): ...`` now raises
+  a :exc:`TypeError`, because ``S`` is not listed in ``Protocol`` parameters.
+  (Contributed by Nikita Sobolev in :gh:`137191`.)
+
+* Code like ``class B2(A[T2], Protocol[T1, T2]): ...`` now correctly handles
+  type parameters order: it is ``(T1, T2)``, not ``(T2, T1)``
+  as it was incorrectly inferred at runtime before.
+  (Contributed by Nikita Sobolev in :gh:`137191`.)
+
+* :pep:`800`: Add :deco:`typing.disjoint_base`, a new decorator marking a class
+  as a disjoint base. This is an advanced feature primarily intended to allow
+  type checkers to faithfully reflect the runtime semantics of types defined
+  as builtins or in compiled extensions. If a class ``C`` is a disjoint base, then
+  child classes of that class cannot inherit from other disjoint bases that are
+  not parent or child classes of ``C``. (Contributed by Jelle Zijlstra in :gh:`148639`.)
+
+* :class:`~typing.TypeVarTuple` now accepts ``bound``, ``covariant``,
+  ``contravariant``, and ``infer_variance`` keyword arguments, matching the
+  interface of :class:`~typing.TypeVar` and :class:`~typing.ParamSpec`.
+  ``bound`` semantics remain undefined in the specification.

+Upgraded JIT compiler
+---------------------
+
+Results from the `pyperformance <https://github.com/python/pyperformance>`__
+benchmark suite report
+`8-9% <https://www.doesjitgobrrr.com/run/2026-04-29>`__
+geometric mean performance improvement for the JIT over the standard CPython
+interpreter built with all optimizations enabled on x86-64 Linux. On AArch64
+macOS, the JIT has a
+`12-13% <https://www.doesjitgobrrr.com/run/2026-04-29>`__
+speedup over the :ref:`tail calling interpreter <whatsnew314-tail-call-interpreter>`
+with all optimizations enabled. The speedups for JIT
+builds versus no JIT builds range from roughly 15% slowdown to over
+100% speedup (ignoring the ``unpack_sequence`` microbenchmark) on
+x86-64 Linux and AArch64 macOS systems.
+
+.. attention::
+    These results are not yet final.
+
+The major upgrades to the JIT are:
+
+* LLVM 21 build-time dependency
+* New tracing frontend
+* Basic register allocation in the JIT
+* More JIT optimizations
+* GDB and GNU ``backtrace()`` unwinding support
+* Better machine code generation
+
+.. rubric:: LLVM 21 build-time dependency
+
+The JIT compiler now uses LLVM 21 for build-time stencil generation. As
+always, LLVM is only needed when building CPython with the JIT enabled;
+end users running Python do not need LLVM installed. Instructions for
+installing LLVM can be found in the `JIT compiler documentation
+<https://github.com/python/cpython/blob/main/Tools/jit/README.md>`__
+for all supported platforms.
+(Contributed by Savannah Ostrowski in :gh:`140973`.)
+
+.. rubric:: A new tracing frontend
+
+The JIT compiler now supports significantly more bytecode operations and
+control flow than in Python 3.14, enabling speedups on a wider variety of
+code. For example, simple Python object creation is now understood by the
+3.15 JIT compiler. Overloaded operations and generators are also partially
+supported. This was made possible by an overhauled JIT tracing frontend
+that records actual execution paths through code, rather than estimating
+them as the previous implementation did.
+(Contributed by Ken Jin in :gh:`139109`. Support for Windows added by
+Mark Shannon in :gh:`141703`.)
+
+.. rubric:: Basic register allocation in the JIT
+
+A basic form of register allocation has been added to the JIT compiler's
+optimizer. This allows the JIT compiler to avoid certain stack operations
+altogether and instead operate on registers. This allows the JIT to produce
+more efficient traces by avoiding reads and writes to memory.
+(Contributed by Mark Shannon in :gh:`135379`.)
+
+.. rubric:: More JIT optimizations
+
+More `constant-propagation <https://en.wikipedia.org/wiki/Constant_folding>`__
+is now performed. This means when the JIT compiler detects that certain user
+code results in constants, the code can be simplified by the JIT.

+
+:term:`Reference count`\ s are avoided whenever it is safe to do so. This generally
+reduces the cost of most operations in Python.
+(Contributed by Ken Jin, Donghee Na, Zheao Li, Hai Zhu, Savannah Ostrowski,
+Reiden Ong, Noam Cohen, Tomas Roun, PuQing, Cajetan Rodrigues, and Sacul in :gh:`134584`.)
+
+By tracking unique references to objects, the JIT optimizer can now eliminate
+reference count updates and perform in-place operations on ints and floats.
+(Contributed by Reiden Ong, and Pieter Eendebak in :gh:`143414` and :gh:`146306`.)
+
+The JIT optimizer now supports significantly more operations than in 3.14.
+(Contributed by Kumar Aditya, Ken Jin, Jiahao Li, and Sacul in :gh:`131798`.)
+
+.. rubric:: GDB and GNU ``backtrace()`` unwinding support
+
+The JIT compiler now publishes unwind information for generated machine code to the
+GDB interface on supported Linux ELF platforms. When libgcc frame
+registration is available, the same unwind information is also registered for
+GNU ``backtrace()`` stack walkers. This allows native debuggers, crash
+handlers, and diagnostic tools using these mechanisms to unwind through JIT
+frames instead of stopping at generated code.
+(Contributed by Diego Russo and Pablo Galindo Salgado in :gh:`146071` and
+:gh:`149104`.)
+
+.. rubric:: Better machine code generation
+
+The JIT compiler's machine code generator now produces better machine code
+for x86-64 and AArch64 macOS and Linux targets. In general, users should
+experience lower memory usage for generated machine code and more efficient
+machine code versus 3.14.

+Additional optimizations for AArch64 contributed by Mark Shannon and
+Diego Russo in :gh:`140683` and :gh:`142305`.)

+
+The JIT optimizer's operations have been simplified.
+This was made possible by a refactoring of JIT data structures.

+
+   * Anyone can add text to this document.  Do not spend very much time
+   on the wording of your changes, because your text will probably
+   get rewritten to some degree.
+
+   * The maintainer will go through Misc/NEWS periodically and add
+   changes; it's therefore more important to add your changes to
+   Misc/NEWS than to this file.
+
+   * This is not a complete list of every single change; completeness
+   is the purpose of Misc/NEWS.  Some changes I consider too small
+   or esoteric to include.  If such a change is added to the text,
+   I'll just remove it.  (This is another reason you shouldn't spend
+   too much time on writing your addition.)
+
+   * If you want to draw your new text to the attention of the
+   maintainer, add 'XXX' to the beginning of the paragraph or
+   section.
+
+   * It's OK to just add a fragmentary note about a change.  For
+   example: "XXX Describe the transmogrify() function added to the
+   socket module."  The maintainer will research the change and
+   write the necessary text.
+
+   * You can comment out your additions if you like, but it's not
+   necessary (especially when a final release is some months away).
+
+   * Credit the author of a patch or bugfix.   Just the name is
+   sufficient; the e-mail address isn't necessary.
+
+   * It's helpful to add the issue number as a comment:
+
+   XXX Describe the transmogrify() function added to the socket
+   module.

+

+This article explains the new features in Python 3.16, compared to 3.15.
+
+For full details, see the :ref:`changelog <changelog>`.
+
+.. note::
+
+   Prerelease users should be aware that this document is currently in draft
+   form. It will be updated substantially as Python 3.16 moves towards release,
+   so it's worth checking back even after reading earlier versions.

+
+Improved modules
+================
+
+curses
+------
+
+* Add support for multiple terminals to the :mod:`curses` module:
+  the new functions :func:`curses.newterm`, :func:`curses.set_term`
+  and :func:`curses.new_prescr`,
+  the corresponding :ref:`screen <curses-screen-objects>` object,
+  and the :meth:`window.use() <curses.window.use>` method.
+  (Contributed by Serhiy Storchaka in :gh:`90092`.)
+
+* The :mod:`curses` character-cell window methods now accept a full character
+  cell --- a spacing character optionally followed by combining characters ---
+  in addition to a single integer or byte character.  This affects
+  :meth:`~curses.window.addch`, :meth:`~curses.window.bkgd`,
+  :meth:`~curses.window.bkgdset`, :meth:`~curses.window.border`,
+  :meth:`~curses.window.box`, :meth:`~curses.window.echochar`,
+  :meth:`~curses.window.hline`, :meth:`~curses.window.insch` and
+  :meth:`~curses.window.vline`.
+  Also add the wide-character read methods :meth:`~curses.window.get_wstr` and
+  :meth:`~curses.window.in_wstr`, the counterparts of
+  :meth:`~curses.window.getstr` and :meth:`~curses.window.instr` that return a
+  :class:`str` rather than :class:`bytes`,
+  and the module functions :func:`curses.erasewchar`, :func:`curses.killwchar`
+  and :func:`curses.wunctrl`, the wide-character counterparts of
+  :func:`curses.erasechar`, :func:`curses.killchar` and :func:`curses.unctrl`.
+  On a narrow (non-ncursesw) build the character cell holds a single character
+  without combining marks, representable as one byte in the window's encoding,
+  and :meth:`~curses.window.in_wstr` returns its decoded text.
+  (Contributed by Serhiy Storchaka in :gh:`151757`.)
+
+* The wide-character :mod:`curses` functions and methods
+  :meth:`~curses.window.get_wch`, :meth:`~curses.window.get_wstr`,
+  :func:`curses.unget_wch`, :func:`curses.erasewchar`,
+  :func:`curses.killwchar` and :func:`curses.wunctrl` now also work when Python
+  is not built against a wide-character-aware curses library, on an 8-bit
+  locale, where each character is a single byte in the relevant encoding.
+  :func:`curses.ungetch` now also accepts a one-character string, like
+  :func:`curses.unget_wch`; on a wide-character build it can be any character
+  (previously a multibyte character raised :exc:`OverflowError`).
+  (Contributed by Serhiy Storchaka in :gh:`152470`.)
+
+* Add :func:`curses.nofilter`, which undoes the effect of :func:`curses.filter`.
+  (Contributed by Serhiy Storchaka in :gh:`151744`.)
+
+* Add the :mod:`curses` functions :func:`curses.alloc_pair`,
+  :func:`curses.find_pair`, :func:`curses.free_pair` and
+  :func:`curses.reset_color_pairs` for dynamic color-pair management,
+  available when built against a wide-character ncurses with extended-color
+  support.
+  (Contributed by Serhiy Storchaka in :gh:`151774`.)
+
+* Add :mod:`curses` functions and window methods that report state which could
+  previously only be set, such as :meth:`curses.window.is_keypad`,
+  :meth:`curses.window.getparent` and :func:`curses.is_cbreak`,
+  available when built against an ncurses with ``NCURSES_EXT_FUNCS``.
+  (Contributed by Serhiy Storchaka in :gh:`151776`.)
+
+* Add the :mod:`curses` window methods :meth:`~curses.window.attr_get`,
+  :meth:`~curses.window.attr_set`, :meth:`~curses.window.attr_on`,
+  :meth:`~curses.window.attr_off` and :meth:`~curses.window.color_set`, which
+  pass the color pair as a separate argument instead of packing it into the
+  attribute value, and the corresponding ``WA_*`` attribute constants.
+  (Contributed by Serhiy Storchaka in :gh:`152219`.)
+
+* Add the :class:`curses.complexchar` type, representing a styled
+  character cell (its text, attributes and color pair), and the window
+  methods :meth:`~curses.window.in_wch` and :meth:`~curses.window.getbkgrnd`
+  that return one --- the counterparts of
+  :meth:`~curses.window.inch` and :meth:`~curses.window.getbkgd`.  The
+  character-cell methods, such as :meth:`~curses.window.addch` and
+  :meth:`~curses.window.border`, now also accept a
+  :class:`~curses.complexchar`.  These work whether or not Python was built
+  against a wide-character-aware curses library; on a narrow build a cell holds a
+  single character representable as one byte in the window's encoding (so only
+  8-bit locales are supported).
+  (Contributed by Serhiy Storchaka in :gh:`152233`.)
+
+* Add the :class:`curses.complexstr` type, an immutable run of styled cells
+  (the string counterpart of :class:`~curses.complexchar`), and the window
+  method :meth:`~curses.window.in_wchstr` that returns one.  The string-cell
+  methods :meth:`~curses.window.addstr`, :meth:`~curses.window.addnstr`,
+  :meth:`~curses.window.insstr` and :meth:`~curses.window.insnstr` now also
+  accept a :class:`~curses.complexstr`.  Like :class:`~curses.complexchar`, it
+  works whether or not Python was built against a wide-character-aware curses
+  library.
+  (Contributed by Serhiy Storchaka in :gh:`152233`.)
+
+* Add the :mod:`curses` window method :meth:`~curses.window.dupwin`, which
+  returns a new window that is an independent duplicate of an existing one.
+  (Contributed by Serhiy Storchaka in :gh:`152258`.)
+
+* Add the :mod:`curses` functions :func:`~curses.scr_dump`,
+  :func:`~curses.scr_restore`, :func:`~curses.scr_init` and
+  :func:`~curses.scr_set`, which dump the whole screen to a file and restore it.
+  (Contributed by Serhiy Storchaka in :gh:`152260`.)
+
+* Add the soft-label-key functions to the :mod:`curses` module, which manage a
+  row of labels along the bottom line of the screen:
+  :func:`~curses.slk_init`, :func:`~curses.slk_set`, :func:`~curses.slk_label`,
+  :func:`~curses.slk_refresh`, :func:`~curses.slk_noutrefresh`,
+  :func:`~curses.slk_clear`, :func:`~curses.slk_restore`,
+  :func:`~curses.slk_touch`, the attribute functions
+  :func:`~curses.slk_attron`, :func:`~curses.slk_attroff`,
+  :func:`~curses.slk_attrset`, :func:`~curses.slk_attr`,
+  :func:`~curses.slk_attr_on`, :func:`~curses.slk_attr_off`,
+  :func:`~curses.slk_attr_set`, and :func:`~curses.slk_color`.
+  (Contributed by Serhiy Storchaka in :gh:`152263`.)

+  (Contributed by Serhiy Storchaka in :gh:`152332`.)
+
+* Add the :mod:`curses` key-management functions :func:`~curses.define_key`,
+  :func:`~curses.key_defined` and :func:`~curses.keyok`, available when built
+  against an ncurses with ``NCURSES_EXT_FUNCS``.
+  (Contributed by Serhiy Storchaka in :gh:`152334`.)
+
+* Add the :func:`curses.has_mouse` function and the
+  :meth:`curses.window.mouse_trafo` method, completing the :mod:`curses`

+  (Contributed by Serhiy Storchaka in :gh:`152325`.)
+

+  full Unicode range, including combining characters, when curses is built with
+  wide-character support.
+  (Contributed by Serhiy Storchaka in :gh:`133031`.)
+
+gzip

+* Add :meth:`io.BytesIO.peek` method to read without advancing position.
+  (Contributed by Marcel Martin in :gh:`90533`.)
+
+
+imaplib
+-------
+
+* Add the :meth:`~imaplib.IMAP4.id` method,
+  a wrapper for the ``ID`` command (:rfc:`2971`).
+  (Contributed by Serhiy Storchaka in :gh:`98092`.)
+
+* Add the :meth:`~imaplib.IMAP4.move` method,
+  a wrapper for the ``MOVE`` command (:rfc:`6851`).
+  (Contributed by Serhiy Storchaka in :gh:`77508`.)
+
+* Add the :meth:`~imaplib.IMAP4.login_plain` method, which authenticates
+  using the ``PLAIN`` SASL mechanism (:rfc:`4616`) and supports non-ASCII
+  user names and passwords.
+  (Contributed by Przemysław Buczkowski and Serhiy Storchaka in :gh:`89869`.)
+
+
+logging
+-------
+
+* :class:`~logging.handlers.TimedRotatingFileHandler` now uses the creation
+  time instead of the last modification time of an existing log file as
+  the basis for the first rotation after handler creation, if supported by
+  the OS and file system.
+  This allows it to be used in short-running programs that start and end
+  before the rotation interval expires.
+  (Contributed by Iván Márton and Serhiy Storchaka in :gh:`84649`.)
+
+
+lzma
+----
+
+* Add support of new BCJ filters ARM64 and RISC-V via
+  :const:`!lzma.FILTER_ARM64` and :const:`!lzma.FILTER_RISCV`.  Note that the
+  new filters will work only if the runtime library supports them. ARM64 filter
+  requires ``lzma`` 5.4.0 or newer while RISC-V requires 5.6.0 or newer.
+  (Contributed by Chien Wong in :gh:`115988`.)
+
+
+math
+----
+
+* Added trigonometric functions that work in units of half turns, rather than
+  radians. The new functions :func:`math.acospi`, :func:`math.asinpi`,
+  :func:`math.atanpi`, and :func:`math.atan2pi` return half-turn angles. The
+  new functions :func:`math.cospi`, :func:`math.sinpi`, and :func:`math.tanpi`
+  take half-turn angle arguments. These functions are recommended by IEEE
+  754-2019 and standardized in C23.
+  (Contributed by Jeff Epler in :gh:`150534`.)
+
+
+os
+--
+
+* Add :func:`os.pidfd_getfd` for duplicating a file descriptor from another
+  process via a pidfd.  Available on Linux 5.6+.
+  (Contributed by Maurycy Pawłowski-Wieroński in :gh:`149464`.)
+
+
+re
+--
+
+* :mod:`re` now supports set operations and nested sets in character classes,
+  as described in `Unicode Technical Standard #18
+  <https://unicode.org/reports/tr18/>`__: set difference (``[A--B]``),
+  intersection (``[A&&B]``) and union (``[A||B]``), where an operand may be a
+  nested set written in square brackets.  For example, ``[a-z--[aeiou]]``
+  matches an ASCII lowercase consonant.
+  (Contributed by Serhiy Storchaka in :gh:`152100`.)
+
+* Regular expressions now support Unicode property escapes ``\p{...}`` and
+  ``\P{...}``, which match a character by a Unicode property -- for example
+  ``\p{Lu}`` (an uppercase letter), ``\p{Cased}`` or ``\p{ASCII}``.  See
+  :ref:`the regular expression syntax <re-syntax>` for the supported
+  properties.
+  (Contributed by Serhiy Storchaka in :gh:`95555`.)
+
+
+shlex
+-----
+
+* Add keyword-only parameter *force* to :func:`shlex.quote` to force quoting
+  a string, even if it is already safe for a shell without being quoted.
+  (Contributed by Jay Berry in :gh:`148846`.)
+
+
+tkinter
+-------
+
+* Added many :class:`tkinter.ttk.Treeview` methods wrapping the enhanced
+  ``ttk::treeview`` widget commands from Tk 9.1, such as
+  :meth:`~tkinter.ttk.Treeview.sort`, :meth:`~tkinter.ttk.Treeview.search`,
+  :meth:`~tkinter.ttk.Treeview.expand`, :meth:`~tkinter.ttk.Treeview.collapse`,
+  :meth:`~tkinter.ttk.Treeview.hide`, :meth:`~tkinter.ttk.Treeview.unhide`, and
+  methods for cell focus, selection and tagging.  The
+  :meth:`~tkinter.ttk.Treeview.expand` and :meth:`~tkinter.ttk.Treeview.collapse`
+  methods (without recursion) also work on Tk older than 9.1.
+  (Contributed by Serhiy Storchaka in :gh:`151910`.)
+
+* Added new :class:`!tkinter.Text` methods :meth:`~tkinter.Text.edit_canundo`
+  and :meth:`~tkinter.Text.edit_canredo` which return whether an undo or redo
+  is possible.
+  (Contributed by Serhiy Storchaka in :gh:`151674`.)
+
+* Added new :class:`!tkinter.Text` methods :meth:`~tkinter.Text.sync` and
+  :meth:`~tkinter.Text.pendingsync` which control and report the
+  synchronization of the displayed view with the underlying text.
+  (Contributed by Serhiy Storchaka in :gh:`151675`.)
+
+* Added the :meth:`ttk.Style.theme_styles
+  <tkinter.ttk.Style.theme_styles>` method which returns the list of styles
+  defined in a theme.
+  (Contributed by Serhiy Storchaka in :gh:`151920`.)
+
+* Added new :class:`!tkinter.Canvas` methods :meth:`~tkinter.Canvas.rchars`
+  which replaces the text or coordinates of canvas items, and
+  :meth:`~tkinter.Canvas.rotate` which rotates the coordinates of canvas items.
+  (Contributed by Serhiy Storchaka in :gh:`151876`.)
+
+* Added a :meth:`!validate` method to the :class:`!tkinter.Entry` and
+  :class:`!tkinter.Spinbox` widgets, which forces an evaluation of the
+  validation command.
+  (Contributed by Serhiy Storchaka in :gh:`151878`.)
+
+* Added the :meth:`tkinter.Menu.postcascade` method, and the
+  :meth:`~tkinter.Misc.tk_scaling` and :meth:`~tkinter.Misc.tk_inactive`
+  methods which respectively query or set the display scaling factor and
+  report the user idle time.
+  (Contributed by Serhiy Storchaka in :gh:`151881`.)
+
+* Added new window-management methods :meth:`~tkinter.Misc.winfo_isdark`
+  (dark mode detection), :meth:`~tkinter.Wm.wm_iconbadge` (application icon
+  badge) and :meth:`~tkinter.Wm.wm_stackorder` (toplevel stacking order).
+  (Contributed by Serhiy Storchaka in :gh:`151874`.)
+
+* Added the :meth:`~tkinter.Misc.tk_appname`,
+  :meth:`~tkinter.Misc.tk_useinputmethods` and :meth:`~tkinter.Misc.tk_caret`
+  methods, exposing the application send name, the X Input Methods state and
+  the input method caret location.
+  (Contributed by Serhiy Storchaka in :gh:`151886`.)
+
+* Added support for more options in :class:`!tkinter.PhotoImage` methods: the
+  *format* parameter of :meth:`~tkinter.PhotoImage.put`, the *metadata*
+  parameter of :meth:`~tkinter.PhotoImage.put`, :meth:`~tkinter.PhotoImage.read`,
+  :meth:`~tkinter.PhotoImage.write` and :meth:`~tkinter.PhotoImage.data`, and
+  the *withalpha* parameter of :meth:`~tkinter.PhotoImage.get`.
+  (Contributed by Serhiy Storchaka in :gh:`151890`.)
+
+* Added the :meth:`~tkinter.PhotoImage.redither` method which recalculates the
+  dithered image when its data was supplied in pieces.
+  (Contributed by Serhiy Storchaka in :gh:`151888`.)
+
+* :class:`tkinter.OptionMenu` now accepts arbitrary :class:`!tkinter.Menubutton`
+  options as keyword arguments, which can also override its default appearance.
+  (Contributed by Serhiy Storchaka in :gh:`101284`.)
+
+* The :mod:`tkinter.simpledialog` dialogs were modernized to match the look
+  and feel of the native Tk dialogs.
+  :class:`!tkinter.simpledialog.SimpleDialog` and the
+  :func:`~tkinter.simpledialog.askinteger`,
+  :func:`~tkinter.simpledialog.askfloat` and
+  :func:`~tkinter.simpledialog.askstring` dialogs are now built from the themed
+  :mod:`tkinter.ttk` widgets instead of the classic :mod:`tkinter` widgets;
+  the :class:`!tkinter.simpledialog.Dialog` base class still defaults to the
+  classic widgets for compatibility.  Both :class:`!Dialog` and
+  :class:`!SimpleDialog` gained a *use_ttk* parameter that selects between the
+  classic Tk widgets and the themed ttk widgets.  :class:`!SimpleDialog` also
+  gained *bitmap* and
+  *detail* parameters, draws the standard icons with themed images in the
+  ttk version, and accepts mappings of button options as *buttons* entries.
+  (Contributed by Serhiy Storchaka in :gh:`59396`.)
+
+* The :class:`!tkinter.filedialog.FileDialog` dialog and its
+  :class:`!tkinter.filedialog.LoadFileDialog` and
+  :class:`!tkinter.filedialog.SaveFileDialog` subclasses are now built from the
+  themed :mod:`tkinter.ttk` widgets by default instead of the classic
+  :mod:`tkinter` widgets, and gained a *use_ttk* parameter to select between
+  them.
+  (Contributed by Serhiy Storchaka in :gh:`59396`.)
+
+xml
+---
+
+* Add support for multiple multi-byte encodings in the :mod:`XML parser
+  <xml.parsers.expat>`: "cp932", "cp949", "cp950", "Big5", "EUC-JP",
+  "GB2312", "GBK", "johab", and "Shift_JIS".
+  Add partial support (only BMP characters) for multi-byte encodings
+  "Big5-HKSCS", "EUC_JIS-2004", "EUC_JISX0213", "Shift_JIS-2004",
+  "Shift_JISX0213", "utf-8-sig" and non-standard aliases like "UTF8"
+  (without hyphen).
+  The parser now raises :exc:`ValueError` for known unsupported
+  multi-byte encodings such as "ISO-2022-JP" or "raw-unicode-escape"
+  instead of failing later, when encountering non-ASCII data.
+  (Contributed by Serhiy Storchaka in :gh:`62259`.)
+
+zipfile
+-------
+
+* Add :meth:`ZipFile.remove() <zipfile.ZipFile.remove>` to remove a member
+  from an archive's central directory, and
+  :meth:`ZipFile.repack() <zipfile.ZipFile.repack>` to reclaim the space used
+  by the local file entries of removed members.

+=============
+
+re
+--
+
+* Character class escapes (``\d``, ``\D``, ``\s``, ``\S``, ``\w`` and ``\W``)
+  outside a character set, and character sets containing a single such escape
+  (such as ``[\d]`` or ``[^\s]``), are now compiled to a single ``CATEGORY``
+  opcode instead of being wrapped in an ``IN`` block.  This speeds up matching
+  of patterns such as ``\d+`` and reduces the size of the compiled byte code.

+Porting to Python 3.16
+======================
+
+This section lists previously described changes and other bugfixes
+that may require changes to your code.
+
+* In :mod:`tkinter`, the *name* parameter of the
+  :meth:`~tkinter.Misc.wait_variable`, :meth:`~tkinter.Misc.setvar` and
+  :meth:`~tkinter.Misc.getvar` methods and the *value* parameter of
+  :meth:`!setvar` are now required.  Calling these methods without
+  them, which formerly defaulted to ``'PY_VAR'`` and ``'1'``, now raises
+  :exc:`TypeError`.

+
+
+Build changes
+=============
+
+* Remove the bundled copy of the libmpdec_ decimal library from the CPython source tree
+  to simplify maintenance and updates. The :mod:`decimal` module will now
+  unconditionally use the system's libmpdec decimal library. Also remove the
+  now unused :option:`!--with-system-libmpdec` :program:`configure` flag.
+  This change has no impact on binary releases of Python, which have been
+  built against a separate copy of libmpdec for the past several releases.
+
+  (Contributed by Sergey B Kirpichev in :gh:`115119`.)
+
+  .. _libmpdec: https://www.bytereef.org/mpdecimal/
+
+* Add a :option:`--with-build-details-suffix` configure flag to allow
+  Linux distributions that co-install multiple versions of Python in the
+  same tree to avoid ``build-details.json`` clashes.

-// Python critical sections
-//
-// Conceptually, critical sections are a deadlock avoidance layer on top of
-// per-object locks. These helpers, in combination with those locks, replace
-// our usage of the global interpreter lock to provide thread-safety for
-// otherwise thread-unsafe objects, such as dict.
-//
-// NOTE: These APIs are no-ops in non-free-threaded builds.

 // Straightforward per-object locking could introduce deadlocks that were not
 // present when running with the GIL. Threads may hold locks for multiple
 // objects simultaneously because Python operations can nest. If threads were

 // `_PyThreadState_Attach()`, it resumes the top-most (i.e., most recent)
 // critical section by reacquiring the associated lock or locks.  See
 // `_PyCriticalSection_Resume()`.
-//
-// NOTE: Only the top-most critical section is guaranteed to be active.
-// Operations that need to lock two objects at once must use
-// `Py_BEGIN_CRITICAL_SECTION2()`. You *CANNOT* use nested critical sections
-// to lock more than one object at once, because the inner critical section
-// may  suspend the outer critical sections. This API does not provide a way
-// to lock more than two objects at once (though it could be added later
-// if actually needed).
-//
-// NOTE: Critical sections implicitly behave like reentrant locks because
-// attempting to acquire the same lock will suspend any outer (earlier)
-// critical sections. However, they are less efficient for this use case than
-// purposefully designed reentrant locks.
-//
-// Example usage:
-//  Py_BEGIN_CRITICAL_SECTION(op);
-//  ...
-//  Py_END_CRITICAL_SECTION();

+//
+// Conceptually, critical sections are a deadlock avoidance layer on top of

+// otherwise thread-unsafe objects, such as dict.
+//
+// NOTE: These APIs are no-ops in non-free-threaded builds.
+//
+// NOTE: Only the top-most critical section is guaranteed to be active.
+// Operations that need to lock two objects at once must use
+// `Py_BEGIN_CRITICAL_SECTION2()`. You *CANNOT* use nested critical sections
+// to lock more than one object at once, because the inner critical section
+// may suspend the outer critical sections. This API does not provide a way
+// to lock more than two objects at once (though it could be added later
+// if actually needed).
+//
+// NOTE: Critical sections implicitly behave like reentrant locks because
+// attempting to acquire the same lock will suspend any outer (earlier)
+// critical sections. However, they are less efficient for this use case than
+// purposefully designed reentrant locks.
+//
+// Example usage:
+//  Py_BEGIN_CRITICAL_SECTION(op);
+//  ...
+//  Py_END_CRITICAL_SECTION();

 instruction which cleans up the shim frame and returns.
 
 
+### Base frame
+
+Each thread state contains an embedded `_PyInterpreterFrame` called the "base frame"
+that serves as a sentinel at the bottom of the frame stack. This frame is allocated
+in `_PyThreadStateImpl` (the internal extension of `PyThreadState`) and initialized
+when the thread state is created. The `owner` field is set to `FRAME_OWNED_BY_INTERPRETER`.
+
+External profilers and sampling tools can validate that they have successfully unwound
+the complete call stack by checking that the frame chain terminates at the base frame.
+The `PyThreadState.base_frame` pointer provides the expected address to compare against.
+If a stack walk doesn't reach this frame, the sample is incomplete (possibly due to a
+race condition) and should be discarded.
+
+The base frame is embedded in `_PyThreadStateImpl` rather than `PyThreadState` because
+`_PyInterpreterFrame` is defined in internal headers that cannot be exposed in the
+public API. A pointer (`PyThreadState.base_frame`) is provided for profilers to access
+the address without needing internal headers.
+
+See the initialization in `new_threadstate()` in [Python/pystate.c](../Python/pystate.c).
+
+#### How profilers should use the base frame
+
+External profilers should read `tstate->base_frame` before walking the stack, then
+walk from `tstate->current_frame` following `frame->previous` pointers until reaching
+a frame with `owner == FRAME_OWNED_BY_INTERPRETER`. After the walk, verify that the
+last frame address matches `base_frame`. If not, discard the sample as incomplete
+since the frame chain may have been in an inconsistent state due to concurrent updates.
+
+
+### Remote Profiling Frame Cache
+
+The `last_profiled_frame` and `last_profiled_frame_seq` fields in
+`PyThreadState` support an optimization for remote profilers that sample call
+stacks from external processes. When a remote profiler reads the call stack, it
+writes the current frame address to `last_profiled_frame`. The eval loop then
+keeps this pointer valid by updating it to the parent frame whenever a frame
+returns (in `_PyEval_FrameClearAndPop`) and increments the sequence.
+
+This creates a "high-water mark" that always points to a frame still on the stack.
+On subsequent samples, the profiler can walk from `current_frame` until it reaches
+`last_profiled_frame`, then validate the pointer and sequence before using cached
+callers. This prevents a later frame that reuses the same `_PyInterpreterFrame`
+address from being mistaken for the sampled frame. The cache significantly
+reduces the amount of remote memory reads needed when call stacks are deep and
+stable at their base.
+
+The update in `_PyEval_FrameClearAndPop` is guarded: it only advances the
+pointer and sequence when `last_profiled_frame` is non-NULL AND matches the
+frame being popped. This prevents transient frames (called and returned between
+profiler samples) from corrupting the cache anchor, while avoiding any overhead
+when profiling is inactive.

 generational hypothesis: Most objects die young.
@@ -368,76 +373,29 @@ This has proven to be very close to the reality of many Python
 programs as many temporary objects are created and destroyed very quickly.
 
 To take advantage of this fact, all container objects are segregated into
-two generations: young and old. Every new object starts in the young generation.
-Each garbage collection scans the entire young generation and part of the old generation.
-
-The time taken to scan the young generation can be controlled by controlling its
-size, but the size of the old generation cannot be controlled.
-In order to keep pause times down, scanning of the old generation of the heap
-occurs in increments.
-
-To keep track of what has been scanned, the old generation contains two lists:
-
-* Those objects that have not yet been scanned, referred to as the `pending` list.
-* Those objects that have been scanned, referred to as the `visited` list.
-
-To detect and collect all unreachable objects in the heap, the garbage collector
-must scan the whole heap. This whole heap scan is called a full scavenge.
-
-Increments
-----------
-
-Each full scavenge is performed in a series of increments.
-For each full scavenge, the combined increments will cover the whole heap.
-
-Each increment is made up of:
-
-* The young generation
-* The old generation's least recently scanned objects
-* All objects reachable from those objects that have not yet been scanned this full scavenge
-
-The surviving objects (those that are not collected) are moved to the back of the
-`visited` list in the old generation.
-
-When a full scavenge starts, no objects in the heap are considered to have been scanned,
-so all objects in the old generation must be in the `pending` space.
-When all objects in the heap have been scanned a cycle ends, and all objects are moved
-to the `pending` list again. To avoid having to traverse the entire list, which list is
-`pending` and which is `visited` is determined by a field in the `GCState` struct.
-The `visited` and `pending` lists can be swapped by toggling this bit.
-
-Correctness
------------
-
-The [algorithm for identifying cycles](#Identifying-reference-cycles) will find all
-unreachable cycles in a list of objects, but will not find any cycles that are
-even partly outside of that list.
-Therefore, to be guaranteed that a full scavenge will find all unreachable cycles,
-each cycle must be fully contained within a single increment.
-
-To make sure that no partial cycles are included in the increment we perform a
-[transitive closure](https://en.wikipedia.org/wiki/Transitive_closure)
-over reachable, unscanned objects from the initial increment.
-Since the transitive closure of objects reachable from an object must be a (non-strict)
-superset of any unreachable cycle including that object, we are guaranteed that a
-transitive closure cannot contain any partial cycles.
-We can exclude scanned objects, as they must have been reachable when scanned.
-If a scanned object becomes part of an unreachable cycle after being scanned, it will
-not be collected at this time, but it will be collected in the next full scavenge.

+Collecting the oldest generation
+--------------------------------
+
+In addition to the various configurable thresholds, the GC only triggers a full
+collection of the oldest generation if the ratio `long_lived_pending / long_lived_total`
+is above a given value (hardwired to 25%). The reason is that, while "non-full"
+collections (that is, collections of the young and middle generations) will always
+examine roughly the same number of objects (determined by the aforementioned
+thresholds) the cost of a full collection is proportional to the total
+number of long-lived objects, which is virtually unbounded.  Indeed, it has
+been remarked that doing a full collection every <constant number> of object
+creations entails a dramatic performance degradation in workloads which consist
+of creating and storing lots of long-lived objects (for example, building a large list
+of GC-tracked objects would show quadratic performance, instead of linear as
+expected). Using the above ratio, instead, yields amortized linear performance
+in the total number of objects (the effect of which can be summarized thusly:
+"each full garbage collection is more and more costly as the number of objects
+grows, but we do fewer and fewer of them").
+
 
 Optimization: excluding reachable objects
 =========================================
 
 An object cannot be garbage if it can be reached. To avoid having to identify
-reference cycles across the whole heap, we can reduce the amount of work done
-considerably by first identifying objects reachable from objects known to be
-alive.  These objects are excluded from the normal cyclic detection process.
-
-The default and free-threaded build both implement this optimization but in
-slightly different ways.
-
-Finding reachable objects for the default build GC
---------------------------------------------------
-
-This works by first moving most reachable objects to the `visited` space.
-Empirically, most reachable objects can be reached from a small set of global
-objects and local variables. This step does much less work per object, so
-reduces the time spent performing garbage collection by at least half.
-
-> [!NOTE]
-> Objects that are not determined to be reachable by this pass are not necessarily
-> unreachable. We still need to perform the main algorithm to determine which objects
-> are actually unreachable.
-We use the same technique of forming a transitive closure as the incremental
-collector does to find reachable objects, seeding the list with some global
-objects and the currently executing frames.
-
-This phase moves objects to the `visited` space, as follows:
-
-1. All objects directly referred to by any builtin class, the `sys` module, the `builtins`
-module and all objects directly referred to from stack frames are added to a working
-set of reachable objects.
-2. Until this working set is empty:
-   1. Pop an object from the set and move it to the `visited` space
-   2. For each object directly reachable from that object:
-      * If it is not already in `visited` space and it is a GC object,
-        add it to the working set
-
-

+# Profiling Binary Format
+
+The profiling module includes a binary file format for storing sampling
+profiler data. This document describes the format's structure and the
+design decisions behind it.
+
+The implementation is in
+[`Modules/_remote_debugging/binary_io_writer.c`](../Modules/_remote_debugging/binary_io_writer.c)
+and [`Modules/_remote_debugging/binary_io_reader.c`](../Modules/_remote_debugging/binary_io_reader.c),
+with declarations in
+[`Modules/_remote_debugging/binary_io.h`](../Modules/_remote_debugging/binary_io.h).
+
+## Overview
+
+The sampling profiler can generate enormous amounts of data. A typical
+profiling session sampling at 1000 Hz for 60 seconds produces 60,000 samples.
+Each sample contains a full call stack, often 20-50 frames deep, and each
+frame includes a filename, function name, and line number. In a text-based
+format like collapsed stacks, this would mean repeating the same long file
+paths and function names thousands of times.
+
+The binary format addresses this through two key strategies:
+
+1. **Deduplication**: Strings and frames are stored once in lookup tables,
+   then referenced by small integer indices. A 100-character file path that
+   appears in 50,000 samples is stored once, not 50,000 times.
+
+2. **Compact encoding**: Variable-length integers (varints) encode small
+   values in fewer bytes. Since most indices are small (under 128), they
+   typically need only one byte instead of four.
+
+Together with optional zstd compression, these techniques reduce file sizes
+by 10-50x compared to text formats while also enabling faster I/O.
+
+## File Layout
+
+The file consists of five sections:
+
+```
++------------------+  Offset 0
+|     Header       |  64 bytes (fixed)
++------------------+  Offset 64
+|                  |
+|   Sample Data    |  Variable size (optionally compressed)
+|                  |
++------------------+  string_table_offset
+|   String Table   |  Variable size
++------------------+  frame_table_offset
+|   Frame Table    |  Variable size
++------------------+  file_size - 32
+|     Footer       |  32 bytes (fixed)
++------------------+  file_size
+```
+
+The layout is designed for streaming writes during profiling. The profiler
+cannot know in advance how many unique strings or frames will be encountered,
+so these tables must be built incrementally and written at the end.
+
+The header comes first so readers can quickly validate the file and locate
+the metadata tables. The sample data follows immediately, allowing the writer
+to stream samples directly to disk (or through a compression stream) without
+buffering the entire dataset in memory.
+
+The string and frame tables are placed after sample data because they grow
+as new unique entries are discovered during profiling. By deferring their
+output until finalization, the writer avoids the complexity of reserving
+space or rewriting portions of the file.
+
+The footer at the end contains counts needed to allocate arrays before
+parsing the tables. Placing it at a fixed offset from the end (rather than
+at a variable offset recorded in the header) means readers can locate it
+with a single seek to `file_size - 32`, without first reading the header.
+
+## Header
+
+```
+ Offset   Size   Type      Description
++--------+------+---------+----------------------------------------+
+|    0   |  4   | uint32  | Magic number (0x54414348 = "TACH")     |
+|    4   |  4   | uint32  | Format version                         |
+|    8   |  4   | bytes   | Python version (major, minor, micro,   |
+|        |      |         | reserved)                              |
+|   12   |  8   | uint64  | Start timestamp (microseconds)         |
+|   20   |  8   | uint64  | Sample interval (microseconds)         |
+|   28   |  4   | uint32  | Total sample count                     |
+|   32   |  4   | uint32  | Thread count                           |
+|   36   |  8   | uint64  | String table offset                    |
+|   44   |  8   | uint64  | Frame table offset                     |
+|   52   |  4   | uint32  | Compression type (0=none, 1=zstd)      |
+|   56   |  8   | bytes   | Reserved (zero-filled)                 |
++--------+------+---------+----------------------------------------+
+```
+
+The magic number `0x54414348` ("TACH" for Tachyon) identifies the file format
+and also serves as an **endianness marker**. When read on a system with
+different byte order than the writer, it appears as `0x48434154`. The reader
+uses this to detect cross-endian files and automatically byte-swap all
+multi-byte integer fields.
+
+The Python version field records the major, minor, and micro version numbers
+of the Python interpreter that generated the file. This allows analysis tools
+to detect version mismatches when replaying data collected on a different
+Python version, which may have different internal structures or behaviors.
+
+The header is written as zeros initially, then overwritten with actual values
+during finalization. This requires the output stream to be seekable, which
+is acceptable since the format targets regular files rather than pipes or
+network streams.
+
+## Sample Data
+
+Sample data begins at offset 64 and extends to `string_table_offset`. Samples
+use delta compression to minimize redundancy when consecutive samples from the
+same thread have identical or similar call stacks.
+
+### Stack Encoding Types
+
+Each sample record begins with thread identification, then an encoding byte:
+
+| Code | Name | Description |
+|------|------|-------------|
+| 0x00 | REPEAT | RLE: identical stack repeated N times |
+| 0x01 | FULL | Complete stack (first sample or no match) |
+| 0x02 | SUFFIX | Shares N frames from bottom of previous stack |
+| 0x03 | POP_PUSH | Remove M frames from top, add N new frames |
+
+### Record Formats
+
+**REPEAT (0x00) - Run-Length Encoded Identical Stacks:**
+```
++-----------------+-----------+----------------------------------------+
+| thread_id       | 8 bytes   | Thread identifier (uint64, fixed)      |
+| interpreter_id  | 4 bytes   | Interpreter ID (uint32, fixed)         |
+| encoding        | 1 byte    | 0x00 (REPEAT)                          |
+| count           | varint    | Number of samples in this RLE group    |
+| samples         | varies    | Interleaved: [delta: varint, status: 1]|
+|                 |           | repeated count times                   |
++-----------------+-----------+----------------------------------------+
+```
+The stack is inherited from this thread's previous sample. Each sample in the
+group gets its own timestamp delta and status byte, stored as interleaved pairs
+(delta1, status1, delta2, status2, ...) rather than separate arrays.
+
+**FULL (0x01) - Complete Stack:**
+```
++-----------------+-----------+----------------------------------------+
+| thread_id       | 8 bytes   | Thread identifier (uint64, fixed)      |
+| interpreter_id  | 4 bytes   | Interpreter ID (uint32, fixed)         |
+| encoding        | 1 byte    | 0x01 (FULL)                            |
+| timestamp_delta | varint    | Microseconds since thread's last sample|
+| status          | 1 byte    | Thread state flags                     |
+| stack_depth     | varint    | Number of frames in call stack         |
+| frame_indices   | varint[]  | Array of frame table indices           |
++-----------------+-----------+----------------------------------------+
+```
+Used for the first sample from a thread, or when delta encoding would not
+provide savings.
+
+**SUFFIX (0x02) - Shared Suffix Match:**
+```
++-----------------+-----------+----------------------------------------+
+| thread_id       | 8 bytes   | Thread identifier (uint64, fixed)      |
+| interpreter_id  | 4 bytes   | Interpreter ID (uint32, fixed)         |
+| encoding        | 1 byte    | 0x02 (SUFFIX)                          |
+| timestamp_delta | varint    | Microseconds since thread's last sample|
+| status          | 1 byte    | Thread state flags                     |
+| shared_count    | varint    | Frames shared from bottom of prev stack|
+| new_count       | varint    | New frames at top of stack             |
+| new_frames      | varint[]  | Array of new_count frame indices       |
++-----------------+-----------+----------------------------------------+
+```
+Used when a function call added frames to the top of the stack. The shared
+frames from the previous stack are kept, and new frames are prepended.
+
+**POP_PUSH (0x03) - Pop and Push:**
+```
++-----------------+-----------+----------------------------------------+
+| thread_id       | 8 bytes   | Thread identifier (uint64, fixed)      |
+| interpreter_id  | 4 bytes   | Interpreter ID (uint32, fixed)         |
+| encoding        | 1 byte    | 0x03 (POP_PUSH)                        |
+| timestamp_delta | varint    | Microseconds since thread's last sample|
+| status          | 1 byte    | Thread state flags                     |
+| pop_count       | varint    | Frames to remove from top of prev stack|
+| push_count      | varint    | New frames to add at top               |
+| new_frames      | varint[]  | Array of push_count frame indices      |
++-----------------+-----------+----------------------------------------+
+```
+Used when the code path changed: some frames were popped (function returns)
+and new frames were pushed (different function calls).
+
+### Thread and Interpreter Identification
+
+Thread IDs are 64-bit values that can be large (memory addresses on some
+platforms) and vary unpredictably. Using a fixed 8-byte encoding avoids
+the overhead of varint encoding for large values and simplifies parsing
+since the reader knows exactly where each field begins.
+
+The interpreter ID identifies which Python sub-interpreter the thread
+belongs to, allowing analysis tools to separate activity across interpreters
+in processes using multiple sub-interpreters.
+
+### Status Byte
+
+The status byte is a bitfield encoding thread state at sample time:
+
+| Bit | Flag                  | Meaning                                    |
+|-----|-----------------------|--------------------------------------------|
+|  0  | THREAD_STATUS_HAS_GIL | Thread holds the GIL (Global Interpreter Lock) |
+|  1  | THREAD_STATUS_ON_CPU  | Thread is actively running on a CPU core   |
+|  2  | THREAD_STATUS_UNKNOWN | Thread state could not be determined       |
+|  3  | THREAD_STATUS_GIL_REQUESTED | Thread is waiting to acquire the GIL  |
+|  4  | THREAD_STATUS_HAS_EXCEPTION | Thread has a pending exception         |
+
+Multiple flags can be set simultaneously (e.g., a thread can hold the GIL
+while also running on CPU). Analysis tools use these to filter samples or
+visualize thread states over time.
+
+### Timestamp Delta Encoding
+
+Timestamps use delta encoding rather than absolute values. Absolute
+timestamps in microseconds require 8 bytes each, but consecutive samples
+from the same thread are typically separated by the sampling interval
+(e.g., 1000 microseconds), so the delta between them is small and fits
+in 1-2 varint bytes. The writer tracks the previous timestamp for each
+thread separately. The first sample from a thread encodes its delta from
+the profiling start time; subsequent samples encode the delta from that
+thread's previous sample. This per-thread tracking is necessary because
+samples are interleaved across threads in arrival order, not grouped by
+thread.
+
+For REPEAT (RLE) records, timestamp deltas and status bytes are stored as
+interleaved pairs (delta, status, delta, status, ...) - one pair per
+repeated sample - allowing efficient batching while preserving the exact
+timing and state of each sample.
+
+### Frame Indexing
+
+Each frame in a call stack is represented by an index into the frame table
+rather than inline data. This provides massive space savings because call
+stacks are highly repetitive: the same function appears in many samples
+(hot functions), call stacks often share common prefixes (main -> app ->
+handler -> ...), and recursive functions create repeated frame sequences.
+A frame index is typically 1-2 varint bytes. Inline frame data would be
+20-200+ bytes (two strings plus a line number). For a profile with 100,000
+samples averaging 30 frames each, this reduces frame data from potentially
+gigabytes to tens of megabytes.
+
+Frame indices are written innermost-first (the currently executing frame
+has index 0 in the array). This ordering works well with delta compression:
+function calls typically add frames at the top (index 0), while shared
+frames remain at the bottom.
+
+## String Table
+
+The string table stores deduplicated UTF-8 strings (filenames and function
+names). It begins at `string_table_offset` and contains entries in order of
+their assignment during writing:
+
+```
++----------------+
+| length: varint |
+| data: bytes    |
++----------------+  (repeated for each string)
+```
+
+Strings are stored in the order they were first encountered during writing.
+The first unique filename gets index 0, the second gets index 1, and so on.
+Length-prefixing (rather than null-termination) allows strings containing
+null bytes and enables readers to allocate exact-sized buffers. The varint
+length encoding means short strings (under 128 bytes) need only one length
+byte.
+
+## Frame Table
+
+The frame table stores deduplicated frame entries with full source position
+information and bytecode opcode:
+
+```
++----------------------------+
+| filename_idx: varint       |
+| funcname_idx: varint       |
+| lineno: svarint            |
+| end_lineno_delta: svarint  |
+| column: svarint            |
+| end_column_delta: svarint  |
+| opcode: u8                 |
++----------------------------+  (repeated for each frame)
+```
+
+### Field Definitions
+
+| Field            | Type          | Description                                              |
+|------------------|---------------|----------------------------------------------------------|
+| filename_idx     | varint        | Index into string table for file name                    |
+| funcname_idx     | varint        | Index into string table for function name                |
+| lineno           | zigzag varint | Start line number (-1 for synthetic frames)              |
+| end_lineno_delta | zigzag varint | Delta from lineno (end_lineno = lineno + delta)          |
+| column           | zigzag varint | Start column offset in UTF-8 bytes (-1 if not available) |
+| end_column_delta | zigzag varint | Delta from column (end_column = column + delta)          |
+| opcode           | u8            | Python bytecode opcode (0-254) or 255 for None           |
+
+### Delta Encoding
+
+Position end values use delta encoding for efficiency:
+
+- `end_lineno = lineno + end_lineno_delta`
+- `end_column = column + end_column_delta`
+
+Typical values:
+- `end_lineno_delta`: Usually 0 (single-line expressions) → encodes to 1 byte
+- `end_column_delta`: Usually 5-20 (expression width) → encodes to 1 byte
+
+This saves ~1-2 bytes per frame compared to absolute encoding. When the base
+value (lineno or column) is -1 (not available), the delta is stored as 0 and
+the reconstructed value is -1.
+
+### Sentinel Values
+
+- `opcode = 255`: No opcode captured
+- `lineno = -1`: Synthetic frame (no source location)
+- `column = -1`: Column offset not available
+
+### Deduplication
+
+Each unique (filename, funcname, lineno, end_lineno, column, end_column,
+opcode) combination gets one entry. This enables instruction-level profiling
+where multiple bytecode instructions on the same line can be distinguished.
+
+Strings and frames are deduplicated separately because they have different
+cardinalities and reference patterns. A codebase might have hundreds of
+unique source files but thousands of unique functions. Many functions share
+the same filename, so storing the filename index in each frame entry (rather
+than the full string) provides an additional layer of deduplication. A frame
+entry is typically 7-9 bytes rather than two full strings plus location data.
+
+### Size Analysis
+
+Typical frame size with delta encoding:
+- file_idx: 1-2 bytes
+- func_idx: 1-2 bytes
+- lineno: 1-2 bytes
+- end_lineno_delta: 1 byte (usually 0)
+- column: 1 byte (usually < 64)
+- end_column_delta: 1 byte (usually < 64)
+- opcode: 1 byte
+
+**Total: ~7-9 bytes per frame**
+
+Line numbers and columns use signed varint (zigzag encoding) to handle
+sentinel values efficiently. Synthetic frames—generated frames that don't
+correspond directly to Python source code, such as C extension boundaries or
+internal interpreter frames—use -1 to indicate the absence of a source
+location. Zigzag encoding ensures these small negative values encode
+efficiently (−1 becomes 1, which is one byte) rather than requiring the
+maximum varint length.
+
+## Footer
+
+```
+ Offset   Size   Type      Description
++--------+------+---------+----------------------------------------+
+|    0   |  4   | uint32  | String count                           |
+|    4   |  4   | uint32  | Frame count                            |

++--------+------+---------+----------------------------------------+
+```
+
+The string and frame counts allow readers to pre-allocate arrays of the
+correct size before parsing the tables. Without these counts, readers would
+need to either scan the tables twice (once to count, once to parse) or use
+dynamically-growing arrays.
+
+The file size field provides a consistency check: if the actual file size
+does not match, the file may be truncated or corrupted.
+
+The checksum field is reserved for future use. A checksum would allow
+detection of corruption but adds complexity and computation cost. The
+current implementation leaves this as zeros.
+
+## Variable-Length Integer Encoding
+
+The format uses LEB128 (Little Endian Base 128) for unsigned integers and
+zigzag + LEB128 for signed integers. These encodings are widely used
+(Protocol Buffers, DWARF debug info, WebAssembly) and well-understood.
+
+### Unsigned Varint (LEB128)
+
+Each byte stores 7 bits of data. The high bit indicates whether more bytes
+follow:
+
+```
+Value        Encoded bytes
+0-127        [0xxxxxxx]                    (1 byte)
+128-16383    [1xxxxxxx] [0xxxxxxx]         (2 bytes)
+16384+       [1xxxxxxx] [1xxxxxxx] ...     (3+ bytes)
+```
+
+Most indices in profiling data are small. A profile with 1000 unique frames
+needs at most 2 bytes per frame index. The common case (indices under 128)
+needs only 1 byte.
+
+### Signed Varint (Zigzag)
+
+Standard LEB128 encodes −1 as a very large unsigned value, requiring many
+bytes. Zigzag encoding interleaves positive and negative values:
+
+```
+ 0 -> 0    -1 -> 1     1 -> 2    -2 -> 3     2 -> 4
+```
+
+This ensures small-magnitude values (whether positive or negative) encode
+in few bytes.
+
+## Compression
+
+When compression is enabled, the sample data region contains a zstd stream.
+The string table, frame table, and footer remain uncompressed so readers can
+access metadata without decompressing the entire file. A tool that only needs
+to report "this file contains 50,000 samples of 3 threads" can read the header
+and footer without touching the compressed sample data. This also simplifies
+the format: the header's offset fields point directly to the tables rather
+than to positions within a decompressed stream.
+
+Zstd provides an excellent balance of compression ratio and speed. Profiling
+data compresses very well (often 5-10x) due to repetitive patterns: the same
+small set of frame indices appears repeatedly, and delta-encoded timestamps
+cluster around the sampling interval. Zstd's streaming API allows compression
+without buffering the entire dataset. The writer feeds sample data through
+the compressor incrementally, flushing compressed chunks to disk as they
+become available.
+
+Level 5 compression is used as a default. Lower levels (1-3) are faster but
+compress less; higher levels (6+) compress more but slow down writing. Level
+5 provides good compression with minimal impact on profiling overhead.
+
+## Reading and Writing
+
+### Writing
+
+1. Open the output file and write 64 zero bytes as a placeholder header
+2. Initialize empty string and frame dictionaries for deduplication
+3. For each sample:
+   - Intern any new strings, assigning sequential indices
+   - Intern any new frames, assigning sequential indices
+   - Encode the sample record and write to the buffer
+   - Flush the buffer through compression (if enabled) when full
+4. Flush remaining buffered data and finalize compression
+5. Write the string table (length-prefixed strings in index order)
+6. Write the frame table (varint-encoded entries in index order)
+7. Write the footer with final counts
+8. Seek to offset 0 and write the header with actual values
+
+The writer maintains two dictionaries: one mapping strings to indices, one
+mapping (filename_idx, funcname_idx, lineno) tuples to frame indices. These
+enable O(1) lookup during interning.
+
+### Reading
+
+1. Read the header magic number to detect endianness (set `needs_swap` flag
+   if the magic appears byte-swapped)
+2. Validate version and read remaining header fields (byte-swapping if needed)
+3. Seek to end − 32 and read the footer (byte-swapping counts if needed)
+4. Allocate string array of `string_count` elements
+5. Parse the string table, populating the array
+6. Allocate frame array of `frame_count * 3` uint32 elements
+7. Parse the frame table, populating the array
+8. If compressed, decompress the sample data region
+9. Iterate through samples, resolving indices to strings/frames
+   (byte-swapping thread_id and interpreter_id if needed)
+
+The reader builds lookup arrays rather than dictionaries since it only needs
+index-to-value mapping, not value-to-index.
+
+## Platform Considerations
+
+### Byte Ordering and Cross-Platform Portability
+
+The binary format uses **native byte order** for all multi-byte integer
+fields when writing. However, the reader supports **cross-endian reading**:
+files written on a little-endian system (x86, ARM) can be read on a
+big-endian system (s390x, PowerPC), and vice versa.
+
+The magic number doubles as an endianness marker. When read on a system with
+different byte order, it appears byte-swapped (`0x48434154` instead of
+`0x54414348`). The reader detects this and automatically byte-swaps all
+fixed-width integer fields during parsing.
+
+Writers must use `memcpy()` from properly-sized integer types when writing
+fixed-width integer fields. When the source variable's type differs from the
+field width (e.g., `size_t` written as 4 bytes), explicit casting to the
+correct type (e.g., `uint32_t`) is required before `memcpy()`. On big-endian
+systems, copying from an oversized type would copy the wrong bytes—high-order
+zeros instead of the actual value.
+
+The reader tracks whether byte-swapping is needed via a `needs_swap` flag set
+during header parsing. All fixed-width fields in the header, footer, and
+sample data are conditionally byte-swapped using Python's internal byte-swap
+functions (`_Py_bswap32`, `_Py_bswap64` from `pycore_bitutils.h`).
+
+Variable-length integers (varints) are byte-order independent since they
+encode values one byte at a time using the LEB128 scheme, so they require
+no special handling for cross-endian reading.
+
+### Memory-Mapped I/O
+
+On Unix systems (Linux, macOS), the reader uses `mmap()` to map the file
+into the process address space. The kernel handles paging data in and out
+as needed, no explicit read() calls or buffer management are required,
+multiple readers can share the same physical pages, and sequential access
+patterns benefit from kernel read-ahead.
+
+The implementation uses `madvise()` to hint the access pattern to the kernel:
+`MADV_SEQUENTIAL` indicates the file will be read linearly, enabling
+aggressive read-ahead. `MADV_WILLNEED` requests pre-faulting of pages.
+On Linux, `MAP_POPULATE` pre-faults all pages at mmap time rather than on
+first access, moving page fault overhead from the parsing loop to the
+initial mapping for more predictable performance. For large files (over
+32 MB), `MADV_HUGEPAGE` requests transparent huge pages (2 MB instead of
+4 KB) to reduce TLB pressure when accessing large amounts of data.
+
+On Windows, the implementation falls back to standard file I/O with full
+file buffering. Profiling data files are typically small enough (tens to
+hundreds of megabytes) that this is acceptable.
+
+The writer uses a 512 KB buffer to batch small writes. Each sample record
+is typically tens of bytes; writing these individually would incur excessive
+syscall overhead. The buffer accumulates data until full, then flushes in
+one write() call (or feeds through the compression stream).
+
+## Future Considerations
+
+The format reserves space for future extensions. The 12 reserved bytes in
+the header could hold additional metadata. The 16-byte checksum field in
+the footer is currently unused. The version field allows incompatible
+changes with graceful rejection. New compression types could be added
+(compression_type > 1).
+
+Any changes that alter the meaning of existing fields or the parsing logic
+should increment the version number to prevent older readers from
+misinterpreting new files.

+# Stack references (`_PyStackRef`)
+
+Stack references are the interpreter's tagged representation of values on the evaluation stack.
+They carry metadata to track ownership and support optimizations such as tagged small ints.
+
+## Shape and tagging
+
+- A `_PyStackRef` is a tagged pointer-sized value (see `Include/internal/pycore_stackref.h`).
+- Tag bits distinguish three cases:
+  - `Py_TAG_REFCNT` unset - reference count lives on the pointed-to object.
+  - `Py_TAG_REFCNT` set - ownership is "borrowed" (no refcount to drop on close) or the object is immortal.
+  - `Py_INT_TAG` set - tagged small integer stored directly in the stackref (no heap allocation).
+- Special constants: `PyStackRef_NULL`, `PyStackRef_ERROR`, and embedded `None`/`True`/`False`.
+
+In GIL builds, most objects carry their refcount; tagged borrowed refs skip decref on close. In free
+threading builds, the tag is also used to mark deferred refcounted objects so the GC can see them and
+to avoid refcount contention on commonly shared objects.
+
+## Converting to and from PyObject*
+
+Three conversions control ownership:
+
+- `PyStackRef_FromPyObjectNew(obj)` - create a new reference (INCREF if mortal).
+- `PyStackRef_FromPyObjectSteal(obj)` - take over ownership without changing the count unless the
+  object is immortal.
+- `PyStackRef_FromPyObjectBorrow(obj)` - create a borrowed stackref (never decref on close).
+
+The `obj` argument must not be `NULL`.
+
+Going back to `PyObject*` mirrors this:
+
+- `PyStackRef_AsPyObjectBorrow(ref)` - borrow the underlying pointer
+- `PyStackRef_AsPyObjectSteal(ref)` - transfer ownership from the stackref; if ref is borrowed or
+   deferred, this creates a new owning `PyObject*` reference.
+- `PyStackRef_AsPyObjectNew(ref)` - create a new owning reference
+
+Only `PyStackRef_AsPyObjectBorrow` allows ref to be `PyStackRef_NULL`.
+
+## Operations on stackrefs
+
+The interpreter treats `_PyStackRef` as the unit of stack storage. Ownership must be managed with
+the stackref primitives:
+
+- `PyStackRef_DUP` - like `Py_NewRef` for stackrefs; preserves the original.
+- `PyStackRef_Borrow` - create a borrowed stackref from another stackref.
+- `PyStackRef_CLOSE` / `PyStackRef_XCLOSE` - like `Py_DECREF`; invalidates the stackref.
+- `PyStackRef_CLEAR` - like `Py_CLEAR`; closes and sets the stackref to `PyStackRef_NULL`
+- `PyStackRef_MakeHeapSafe` - converts borrowed reference to owning reference
+
+Borrow tracking (for debug builds with `Py_STACKREF_DEBUG`) records who you borrowed from and reports
+double-close, leaked borrows, or use-after-close via fatal errors.
+
+## Borrow-friendly opcodes
+
+The interpreter can push borrowed references directly. For example, `LOAD_FAST_BORROW` loads a local
+variable as a borrowed `_PyStackRef`, avoiding both INCREF and DECREF for the temporary lifetime on
+the evaluation stack.
+
+## Tagged integers on the stack
+
+Small ints can be stored inline with `Py_INT_TAG`, so no heap object is involved. Helpers like
+`PyStackRef_TagInt`, `PyStackRef_UntagInt`, and `PyStackRef_IncrementTaggedIntNoOverflow` operate on
+these values. Type checks use `PyStackRef_IsTaggedInt` and `PyStackRef_LongCheck`.
+
+## Free threading considerations
+
+Objects that support deferred reference counting can be pushed to the evaluation
+stack and stored in local variables without directly incrementing the reference
+count because they are only freed during cyclic garbage collection. This avoids
+reference count contention on commonly shared objects such as methods and types. The GC
+scans each thread's locals and evaluation stack to keep objects that use
+deferred reference counting alive.
+
+## Debugging support
+
+`Py_STACKREF_DEBUG` builds replace the inline tags with table-backed IDs so the runtime can track
+creation sites, borrows, closes, and leaks. Enabling `Py_STACKREF_CLOSE_DEBUG` additionally records
+double closes. The tables live on `PyInterpreterState` and are initialized in `pystate.c`; helper
+routines reside in `Python/stackrefs.c`.

+# On Finding Cycles
+# -----------------
+# There is a (at least one) total order if and only if the graph is
+# acyclic.
+#
+# When it is cyclic, "there's a cycle - somewhere!" isn't very helpful.
+# In theory, it would be most helpful to partition the graph into
+# strongly connected components (SCCs) and display those with more than
+# one node. Then all cycles could easily be identified "by eyeball".
+#
+# That's a lot of work, though, and we can get most of the benefit much
+# more easily just by showing a single specific cycle.
+#
+# Approaches to that are based on breadth first or depth first search
+# (BFS or DFS). BFS is most natural, which can easily be arranged to
+# find a shortest-possible cycle. But memory burden can be high, because
+# every path-in-progress has to keep its own idea of what "the path" is
+# so far.
+#
+# DFS is much easier on RAM, only requiring keeping track of _the_ path
+# from the starting node to the current node at the current recursion
+# level. But there may be any number of nodes, and so there's no bound
+# on recursion depth short of the total number of nodes.
+#
+# So we use an iterative version of DFS, keeping an exploit list
+# (`stack`) of the path so far. A parallel stack (`itstack`) holds the
+# `__next__` method of an iterator over the current level's node's
+# successors, so when backtracking to a shallower level we can just call
+# that to get the node's next successor. This is state that a recursive
+# version would implicitly store in a `for` loop's internals.
+#
+# `seen()` is a set recording which nodes have already been, at some
+# time, pushed on the stack. If a node has been pushed on the stack, DFS
+# will find any cycle it's part of, so there's no need to ever look at
+# it again.
+#
+# Finally, `node2stacki` maps a node to its index on the current stack,
+# for and only for nodes currently _on_ the stack. If a successor to be
+# pushed on the stack is in that dict, the node is already on the path,
+# at that index. The cycle is then `stack[that_index :] + [node]`.
+#
+# As is often the case when removing recursion, the control flow looks a
+# bit off. The "while True:" loop here rarely actually loops - it's only
+# looking to go "up the stack" until finding a level that has another
+# successor to consider, emulating a chain of returns in a recursive
+# version.
+#
+# Worst cases: O(V+E) for time, and O(V) for memory, where V is the
+# number of nodes and E the number of edges (which may be quadratic in
+# V!). It requires care to ensure these bounds are met.

+What's New in IDLE 3.15.0
+(since 3.14.0)
+Released on 2026-10-01
+=========================
+
+
+gh-152745:  When "Run... Customized" with "Restart shell" unchecked
+while Shell is running code, including waiting for an input('prompt:')
+response, just report that the shell is executing instead of
+reporting twice and restarting anyway.  Patch by Serhiy Storchaka.
+
+gh-152743: When an integer entry in IDLE's Settings dialog, such as
+"Auto squeeze min lines", is deleted, do not save '', which is an
+invalid configuration value.  Patch by Serhiy Storchaka.
+
+gh-152742: MakeChange the default extension when saving a Shell or
+Output window '.txt' and list text files before Python files.  Their
+content is not Python source. Patch by Serhiy Storchaka and Claude Code.
+
+gh-152740: Fill the "In files:" field of IDLE's Find in Files dialog
+with a full directory path, even for an unsaved editor or the Shell.
+In the grep output whow which directory was searched.  Patch by Serhiy
+Storchaka and Claude Code.
+
+gh-152739: Omit the idlelib directory from the path of the IDLE user
+process. User code imports such as `import help' can no longer import
+an idlelib submodule (here idlelib.help) instead of the intended
+top-level module.  Patch by Serhiy Storchaka and Claude Code.
+
+gh-152738: Fix a rare crash in the IDLE editor when the completion
+window is closed: deleting a key binding for a sequence that is not
+bound to the virtual event is now ignored instead of raising a
+ValueError. Patch by Serhiy Storchaka and Claude Code.
+
+gh-152737: Fix Replace All in the IDLE editor's Replace dialog when the
+search direction is "Up" and "Wrap around" is off: it now replaces all
+matches above the current position instead of only the first one.
+Patch by Serhiy Storchaka and Claude Code.
+
+gh-152733: For X11 window managers, set toplevel window classes to
+"Idle".  Patch by Serhiy Storchaka and Claude Code.
+
+gh-152728: Move functions run.fix_scaling, editor.fixwordbreaks
+(as 'fix_word_breaks') and pyshell.fix_x11_paste to module util.
+Patch by Terry J. Reedy.
+
+gh-85320: IDLE now reads and writes its configuration files and the
+breakpoints file using UTF-8 instead of the locale encoding.
+Files with non-ASCII characters and non-UTF-8 encoding may need
+to be opened in an editor and resaved with UTF-8 encoding.
+
+gh-143774: Better explain the operation of Format / Format Paragraph.
+Patch by Terry J. Reedy.
+
+gh-139742: Colorize t-string prefixes for template strings in IDLE,
+as done for f-string prefixes.  Patch by Anuradha Agrawal.
+
 What's New in IDLE 3.14.0
 (since 3.13.0)
 Released on 2025-10-07
 =========================
 
-
 gh-129873: Simplify displaying the IDLE doc by only copying the text
 section of idle.html to idlelib/help.html. Patch by Stan Ulbrych.

+"""JSON Lines (JSONL) collector for the sampling profiler.
+
+Emits a normalized newline-delimited JSON record stream suitable for
+programmatic consumption by external tools, scripts, and agents. Each line
+is one JSON object; consumers can parse the file incrementally line by
+line, but the producer writes the whole file at the end of the run (it is
+not a live/streaming producer).
+
+Record schema
+=============
+
+Every record is a JSON object with at least ``"type"``, ``"v"`` (record
+schema version), and ``"run_id"`` (UUID4 hex tagging the run; allows
+demultiplexing concatenated streams). Records appear in this fixed order:
+
+1. ``meta`` (exactly one, first line)::
+
+      {"type":"meta","v":0,"run_id":"<hex>",
+       "sample_interval_usec":<int>,"mode":"wall|cpu|gil|all|exception"}
+
+   ``mode`` is omitted when not provided.
+
+2. ``string_table`` (zero or more)::
+
+      {"type":"string_table","v":0,"run_id":"<hex>",
+       "strings":[{"str_id":<int>,"value":"<str>"}, ...]}
+
+   Strings (filenames, function names) are interned to keep repeated values
+   compact. IDs are zero-based. Each chunk holds up to ``_CHUNK_SIZE``
+   entries, and each entry carries its explicit ``str_id`` so consumers do
+   not need to infer offsets across chunks.
+
+3. ``frame_table`` (zero or more)::
+
+      {"type":"frame_table","v":0,"run_id":"<hex>",
+       "frames":[{"frame_id":<int>,"path_str_id":<int>,"func_str_id":<int>,
+                  "line":<int>,"end_line":<int>,"col":<int>,
+                  "end_col":<int>}, ...]}
+
+   ``end_line``/``col``/``end_col`` are *omitted* when source location data
+   is unavailable (a missing key means "not available", not zero or null).
+   ``line`` is ``0`` for synthetic frames (for example, internal marker
+   frames whose source location is None). Frame IDs are zero-based.
+
+4. ``agg`` (zero or more)::
+
+      {"type":"agg","v":0,"run_id":"<hex>","kind":"frame","scope":"final",
+       "samples_total":<int>,
+       "entries":[{"frame_id":<int>,"self":<int>,"cumulative":<int>}, ...]}
+
+   ``self`` counts samples where the frame was the leaf (currently
+   executing); ``cumulative`` counts samples where the frame appeared
+   anywhere in the stack (deduped per sample so recursion does not
+   double-count). ``samples_total`` is the run-wide total, repeated on
+   each chunk so a streaming consumer always knows the denominator.
+
+5. ``end`` (exactly one, last line)::
+
+      {"type":"end","v":0,"run_id":"<hex>","samples_total":<int>}
+
+   Presence of ``end`` is the consumer's signal that the file is complete.
+
+Forward compatibility
+=====================
+
+Consumers MUST ignore unknown record ``"type"`` values and unknown object
+fields. New fields will be added by adding optional keys; an incompatible
+schema change will bump the per-record ``"v"``.

+
+Architecture:
+
+The live collector is organized into four layers. The data collection layer
+(LiveStatsCollector) aggregates stack samples into per-function statistics without
+any knowledge of how they will be presented. The display abstraction layer
+(DisplayInterface) defines rendering operations without coupling to curses or any
+specific UI framework. The widget layer (Widget, HeaderWidget, TableWidget,
+FooterWidget, HelpWidget, ProgressBarWidget) encapsulates individual UI components
+with their own rendering logic, promoting modularity and reusability. The
+presentation layer (CursesDisplay/MockDisplay) implements the actual rendering for
+terminal output and testing.
+
+The system runs two independent update loops. The sampling loop is driven by the
+profiler at the configured interval (e.g., 10000µs) and continuously collects
+stack frames and updates statistics. The display loop runs at a fixed refresh rate
+(default 10Hz) and updates the terminal independently of sampling frequency. This
+separation allows high-frequency sampling without overwhelming the terminal with
+constant redraws.
+
+Statistics are computed incrementally as samples arrive. The collector maintains
+running counters (direct calls and cumulative calls) in a dictionary keyed by
+function location. Derived metrics like time estimates and percentages are computed
+on-demand during display updates rather than being stored, which minimizes memory
+overhead as the number of tracked functions grows.
+
+User input is processed asynchronously during display updates using non-blocking I/O.
+This allows interactive controls (sorting, filtering, pausing) without interrupting
+the data collection pipeline. The collector maintains mode flags (paused,
+filter_input_mode) that affect what gets displayed but not what gets collected.

+A *literal* is a textual representation of a value. Python supports
+numeric, string and bytes literals. Format strings and template
+strings are treated as string literals.
+
+Numeric literals consist of a single "NUMBER" token, which names an
+integer, floating-point number, or an imaginary number. See the
+Numeric literals section in Lexical analysis documentation for
+details.
+
+String and bytes literals may consist of several tokens. See section
+String literal concatenation for details.
+
+Note that negative and complex numbers, like "-3" or "3+4.2j", are
+syntactically not literals, but unary or binary arithmetic operations
+involving the "-" or "+" operator.
+
+Evaluation of a literal yields an object of the given type ("int",
+"float", "complex", "str", "bytes", or "Template") with the given
+value. The value may be approximated in the case of floating-point and
+imaginary literals.
+
+The formal grammar for literals is:
 
    literal: strings | NUMBER
 
-Evaluation of a literal yields an object of the given type (string,
-bytes, integer, floating-point number, complex number) with the given
-value.  The value may be approximated in the case of floating-point
-and imaginary (complex) literals. See section Literals for details.
-See section String literal concatenation for details on "strings".

+
+Non-ASCII characters in names
+=============================
+
+Names that contain non-ASCII characters need additional normalization
+and validation beyond the rules and grammar explained above. For
+example, "ř_1", "蛇", or "साँप"  are valid names, but "r〰2", "€", or
+"🐍" are not.
+
+This section explains the exact rules.
+
+All names are converted into the normalization form NFKC while
+parsing. This means that, for example, some typographic variants of
+characters are converted to their “basic” form. For example,
+"fiⁿₐˡᵢᶻₐᵗᵢᵒₙ" normalizes to "finalization", so Python treats them as
+the same name:
+
+   >>> fiⁿₐˡᵢᶻₐᵗᵢᵒₙ = 3
+   >>> finalization
+   3
+
+Note:
+
+  Normalization is done at the lexical level only. Run-time functions
+  that take names as *strings* generally do not normalize their
+  arguments. For example, the variable defined above is accessible at
+  run time in the "globals()" dictionary as
+  "globals()["finalization"]" but not "globals()["fiⁿₐˡᵢᶻₐᵗᵢᵒₙ"]".
+
+Similarly to how ASCII-only names must contain only letters, digits
+and the underscore, and cannot start with a digit, a valid name must
+start with a character in the “letter-like” set "xid_start", and the
+remaining characters must be in the “letter- and digit-like” set
+"xid_continue".
+
+These sets are based on the *XID_Start* and *XID_Continue* sets as
+defined by the Unicode standard annex UAX-31. Python’s "xid_start"
+additionally includes the underscore ("_"). Note that Python does not
+necessarily conform to UAX-31.
+
+A non-normative listing of characters in the *XID_Start* and
+*XID_Continue* sets as defined by Unicode is available in the
+DerivedCoreProperties.txt file in the Unicode Character Database. For
+reference, the construction rules for the "xid_*" sets are given
+below.
+
+The set "id_start" is defined as the union of:
+
+* Unicode category "<Lu>" - uppercase letters (includes "A" to "Z")
+
+* Unicode category "<Ll>" - lowercase letters (includes "a" to "z")
+
+* Unicode category "<Lt>" - titlecase letters
+
+* Unicode category "<Lm>" - modifier letters
+
+* Unicode category "<Lo>" - other letters
+
+* Unicode category "<Nl>" - letter numbers
+
+* {""_""} - the underscore
+
+* "<Other_ID_Start>" - an explicit set of characters in PropList.txt
+  to support backwards compatibility
+
+The set "xid_start" then closes this set under NFKC normalization, by
+removing all characters whose normalization is not of the form
+"id_start id_continue*".
+
+The set "id_continue" is defined as the union of:
+
+* "id_start" (see above)
+
+* Unicode category "<Nd>" - decimal numbers (includes "0" to "9")
+
+* Unicode category "<Pc>" - connector punctuations
+
+* Unicode category "<Mn>" - nonspacing marks
+
+* Unicode category "<Mc>" - spacing combining marks
+
+* "<Other_ID_Continue>" - another explicit set of characters in
+  PropList.txt to support backwards compatibility
+
+Again, "xid_continue" closes this set under NFKC normalization.

+Lazy imports
+============
+
+The "lazy" keyword is a soft keyword that only has special meaning
+when it appears immediately before an "import" or "from" statement.
+When an import statement is preceded by the "lazy" keyword, the import
+becomes *lazy*: the module is not loaded immediately at the import
+statement. Instead, a lazy proxy object is created and bound to the
+name. The actual module is loaded on first use of that name.
+
+Lazy imports are only permitted at module scope. Using "lazy" inside a
+function, class body, or "try"/"except"/"finally" block raises a
+"SyntaxError". Star imports cannot be lazy ("lazy from module import
+*" is a syntax error), and future statements cannot be lazy.
+
+When using "lazy from ... import", each imported name is bound to a
+lazy proxy object. The first access to any of these names triggers
+loading of the entire module and resolves only that specific name to
+its actual value. Other names remain as lazy proxies until they are
+accessed.
+
+Example:
+
+   lazy import json
+   import sys
+
+   print('json' in sys.modules)  # False - json module not yet loaded
+
+   # First use triggers loading
+   result = json.dumps({"hello": "world"})
+
+   print('json' in sys.modules)  # True - now loaded
+
+If an error occurs during module loading (such as "ImportError" or
+"SyntaxError"), it is raised at the point where the lazy import is
+first used, not at the import statement itself.
+
+See **PEP 810** for the full specification of lazy imports.
+
+Added in version 3.15.
+
+
+Compatibility via "__lazy_modules__"
+------------------------------------
+
+As an alternative to using the "lazy" keyword, a module can opt into
+lazy loading for specific imports by defining a module-level
+"__lazy_modules__" variable.  When present, it must be a container of
+fully qualified module name strings.  Any regular (non-"lazy")
+"import" statement at module scope whose target appears in
+"__lazy_modules__" is treated as a lazy import, exactly as if the
+"lazy" keyword had been used.
+
+This provides a way to enable lazy loading for specific dependencies
+without changing individual "import" statements. This is useful when
+supporting Python versions older than 3.15 while using lazy imports in
+3.15+:
+
+   __lazy_modules__ = ["json", "pathlib"]
+
+   import json     # loaded lazily (name is in __lazy_modules__)
+   import os       # loaded eagerly (name not in __lazy_modules__)
+
+   import pathlib  # loaded lazily
+
+Relative imports are resolved to their absolute name before the
+lookup, so "__lazy_modules__" must always contain fully qualified
+module names.
+
+For "from"-style imports, the relevant name is the module following
+"from", not the names of its members:
+
+   # In mypackage/mymodule.py
+   __lazy_modules__ = ["mypackage", "mypackage.sub.utils"]
+
+   from . import helper         # loaded lazily: . resolves to mypackage
+   from .sub.utils import func  # loaded lazily: .sub.utils resolves to mypackage.sub.utils
+   import json                  # loaded eagerly (not in __lazy_modules__)
+
+Imports inside functions, class bodies, or "try"/"except"/"finally"
+blocks are always eager, regardless of "__lazy_modules__".
+
+Setting "-X lazy_imports=none" (or the "PYTHON_LAZY_IMPORTS"
+environment variable to "none") overrides "__lazy_modules__" and
+forces all imports to be eager.
+
+Added in version 3.15.

-A slicing selects a range of items in a sequence object (e.g., a
-string, tuple or list).  Slicings may be used as expressions or as
-targets in assignment or "del" statements.  The syntax for a slicing:
-
-   slicing:      primary "[" slice_list "]"
-   slice_list:   slice_item ("," slice_item)* [","]
-   slice_item:   expression | proper_slice
-   proper_slice: [lower_bound] ":" [upper_bound] [ ":" [stride] ]
-   lower_bound:  expression
-   upper_bound:  expression
-   stride:       expression
-
-There is ambiguity in the formal syntax here: anything that looks like
-an expression list also looks like a slice list, so any subscription
-can be interpreted as a slicing.  Rather than further complicating the
-syntax, this is disambiguated by defining that in this case the
-interpretation as a subscription takes priority over the
-interpretation as a slicing (this is the case if the slice list
-contains no proper slice).
-
-The semantics for a slicing are as follows.  The primary is indexed
-(using the same "__getitem__()" method as normal subscription) with a
-key that is constructed from the slice list, as follows.  If the slice
-list contains at least one comma, the key is a tuple containing the
-conversion of the slice items; otherwise, the conversion of the lone
-slice item is the key.  The conversion of a slice item that is an
-expression is that expression.  The conversion of a proper slice is a
-slice object (see section The standard type hierarchy) whose "start",
-"stop" and "step" attributes are the values of the expressions given
-as lower bound, upper bound and stride, respectively, substituting
-"None" for missing expressions.
+A more advanced form of subscription, *slicing*, is commonly used to
+extract a portion of a sequence. In this form, the subscript is a
+*slice*: up to three expressions separated by colons. Any of the
+expressions may be omitted, but a slice must contain at least one
+colon:
+
+   >>> number_names = ['zero', 'one', 'two', 'three', 'four', 'five']
+   >>> number_names[1:3]
+   ['one', 'two']
+   >>> number_names[1:]

+   >>> number_names[:-3]
+   ['zero', 'one', 'two']
+   >>> del number_names[4:]
+   >>> number_names
+   ['zero', 'one', 'two', 'three']
+
+When a slice is evaluated, the interpreter constructs a "slice" object
+whose "start", "stop" and "step" attributes, respectively, are the

-A *formatted string literal* or *f-string* is a string literal that is
-prefixed with ‘"f"’ or ‘"F"’.  These strings may contain replacement
-fields, which are expressions delimited by curly braces "{}". While
-other string literals always have a constant value, formatted strings
-are really expressions evaluated at run time.
-
-Escape sequences are decoded like in ordinary string literals (except
-when a literal is also marked as a raw string).  After decoding, the
-grammar for the contents of the string is:
-
-   f_string:          (literal_char | "{{" | "}}" | replacement_field)*
-   replacement_field: "{" f_expression ["="] ["!" conversion] [":" format_spec] "}"
-   f_expression:      (conditional_expression | "*" or_expr)
-                        ("," conditional_expression | "," "*" or_expr)* [","]
-                      | yield_expression
-   conversion:        "s" | "r" | "a"
-   format_spec:       (literal_char | replacement_field)*
-   literal_char:      <any code point except "{", "}" or NULL>
-
-The parts of the string outside curly braces are treated literally,
-except that any doubled curly braces "'{{'" or "'}}'" are replaced
-with the corresponding single curly brace.  A single opening curly
-bracket "'{'" marks a replacement field, which starts with a Python
-expression. To display both the expression text and its value after
-evaluation, (useful in debugging), an equal sign "'='" may be added
-after the expression. A conversion field, introduced by an exclamation
-point "'!'" may follow.  A format specifier may also be appended,
-introduced by a colon "':'". A replacement field ends with a closing
-curly bracket "'}'".
-
-Expressions in formatted string literals are treated like regular
-Python expressions surrounded by parentheses, with a few exceptions.
-An empty expression is not allowed, and both "lambda"  and assignment
-expressions ":=" must be surrounded by explicit parentheses. Each
-expression is evaluated in the context where the formatted string
-literal appears, in order from left to right.  Replacement expressions
-can contain newlines in both single-quoted and triple-quoted f-strings
-and they can contain comments.  Everything that comes after a "#"
-inside a replacement field is a comment (even closing braces and
-quotes). In that case, replacement fields must be closed in a
-different line.
-
-   >>> f"abc{a # This is a comment }"
-   ... + 3}"
-   'abc5'
-
-Changed in version 3.7: Prior to Python 3.7, an "await" expression and
-comprehensions containing an "async for" clause were illegal in the
-expressions in formatted string literals due to a problem with the
-implementation.
+Changed in version 3.7: The "await" and "async for" can be used in
+expressions within f-strings.
 
-Changed in version 3.12: Prior to Python 3.12, comments were not
-allowed inside f-string replacement fields.
+Changed in version 3.8: Added the debug specifier ("=")
 
-When the equal sign "'='" is provided, the output will have the
-expression text, the "'='" and the evaluated value. Spaces after the
-opening brace "'{'", within the expression and after the "'='" are all
-retained in the output. By default, the "'='" causes the "repr()" of
-the expression to be provided, unless there is a format specified.
-When a format is specified it defaults to the "str()" of the
-expression unless a conversion "'!r'" is declared.
+Changed in version 3.12: Many restrictions on expressions within
+f-strings have been removed. Notably, nested strings, comments, and
+backslashes are now permitted.

-the result, "'!r'" calls "repr()", and "'!a'" calls "ascii()".
+A *formatted string literal* or *f-string* is a string literal that is
+prefixed with ‘"f"’ or ‘"F"’. Unlike other string literals, f-strings
+do not have a constant value. They may contain *replacement fields*
+delimited by curly braces "{}". Replacement fields contain expressions
+which are evaluated at run time. For example:
+
+   >>> who = 'nobody'
+   >>> nationality = 'Spanish'
+   >>> f'{who.title()} expects the {nationality} Inquisition!'
+   'Nobody expects the Spanish Inquisition!'
+
+Any doubled curly braces ("{{" or "}}") outside replacement fields are
+replaced with the corresponding single curly brace:
+
+   >>> print(f'{{...}}')
+   {...}
+
+Other characters outside replacement fields are treated like in
+ordinary string literals. This means that escape sequences are decoded
+(except when a literal is also marked as a raw string), and newlines
+are possible in triple-quoted f-strings:
+
+   >>> name = 'Galahad'
+   >>> favorite_color = 'blue'
+   >>> print(f'{name}:\\t{favorite_color}')
+   Galahad:       blue
+   >>> print(rf"C:\\Users\\{name}")
+   C:\\Users\\Galahad
+   >>> print(f\'\'\'Three shall be the number of the counting
+   ... and the number of the counting shall be three.\'\'\')
+   Three shall be the number of the counting
+   and the number of the counting shall be three.
 
-The result is then formatted using the "format()" protocol.  The
-format specifier is passed to the "__format__()" method of the
-expression or conversion result.  An empty string is passed when the
-format specifier is omitted.  The formatted result is then included in
-the final value of the whole string.
+Expressions in formatted string literals are treated like regular
+Python expressions. Each expression is evaluated in the context where
+the formatted string literal appears, in order from left to right. An
+empty expression is not allowed, and both "lambda" and assignment
+expressions ":=" must be surrounded by explicit parentheses:

-These nested fields may include their own conversion fields and format
-specifiers, but may not include more deeply nested replacement fields.
-The format specifier mini-language is the same as that used by the

-Formatted string literals may be concatenated, but replacement fields
-cannot be split across literals.

+Formal grammar for f-strings
+============================
+
+F-strings are handled partly by the *lexical analyzer*, which produces
+the tokens "FSTRING_START", "FSTRING_MIDDLE" and "FSTRING_END", and
+partly by the parser, which handles expressions in the replacement
+field. The exact way the work is split is a CPython implementation
+detail.
+
+Correspondingly, the f-string grammar is a mix of lexical and
+syntactic definitions.
+
+Whitespace is significant in these situations:
+
+* There may be no whitespace in "FSTRING_START" (between the prefix
+  and quote).
+
+* Whitespace in "FSTRING_MIDDLE" is part of the literal string
+  contents.
+
+* In "fstring_replacement_field", if "f_debug_specifier" is present,
+  all whitespace after the opening brace until the
+  "f_debug_specifier", as well as whitespace immediately following
+  "f_debug_specifier", is retained as part of the expression.
+
+  **CPython implementation detail:** The expression is not handled in
+  the tokenization phase; it is retrieved from the source code using
+  locations of the "{" token and the token after "=".
+
+The "FSTRING_MIDDLE" definition uses negative lookaheads ("!") to
+indicate special characters (backslash, newline, "{", "}") and
+sequences ("f_quote").
+
+   fstring:    FSTRING_START fstring_middle* FSTRING_END

+Note:
+
+  In the above grammar snippet, the "f_quote" and "FSTRING_MIDDLE"
+  rules are context-sensitive – they depend on the contents of
+  "FSTRING_START" of the nearest enclosing "fstring".Constructing a
+  more traditional formal grammar from this template is left as an
+  exercise for the reader.

+prefix.

+    'subscriptions': r'''Subscriptions and slicings
+**************************
+
+The *subscription* syntax is usually used for selecting an element
+from a container – for example, to get a value from a "dict":
+
+   >>> digits_by_name = {'one': 1, 'two': 2}
+   >>> digits_by_name['two']  # Subscripting a dictionary using the key 'two'
+   2
+
+In the subscription syntax, the object being subscribed – a primary –
+is followed by a *subscript* in square brackets. In the simplest case,
+the subscript is a single expression.
 
-The subscription of an instance of a container class will generally
-select an element from the container. The subscription of a *generic
-class* will generally return a GenericAlias object.
+Depending on the type of the object being subscribed, the subscript is
+sometimes called a *key* (for mappings), *index* (for sequences), or
+*type argument* (for *generic types*). Syntactically, these are all
+equivalent:
 
-   subscription: primary "[" flexible_expression_list "]"
+   >>> colors = ['red', 'blue', 'green', 'black']
+   >>> colors[3]  # Subscripting a list using the index 3
+   'black'
 
-When an object is subscripted, the interpreter will evaluate the
-primary and the expression list.
+   >>> list[str]  # Parameterizing the list type using the type argument str
+   list[str]
 
-The primary must evaluate to an object that supports subscription. An
-object may support subscription through defining one or both of
-"__getitem__()" and "__class_getitem__()". When the primary is
-subscripted, the evaluated result of the expression list will be
-passed to one of these methods. For more details on when
-"__class_getitem__" is called instead of "__getitem__", see
+At runtime, the interpreter will evaluate the primary and the
+subscript, and call the primary’s "__getitem__()" or
+"__class_getitem__()" *special method* with the subscript as argument.
+For more details on which of these methods is called, see
 __class_getitem__ versus __getitem__.
 
-If the expression list contains at least one comma, or if any of the
-expressions are starred, the expression list will evaluate to a
-"tuple" containing the items of the expression list. Otherwise, the
-expression list will evaluate to the value of the list’s sole member.
-
-Changed in version 3.11: Expressions in an expression list may be
-starred. See **PEP 646**.
-
-For built-in objects, there are two types of objects that support
-subscription via "__getitem__()":
-
-1. Mappings. If the primary is a *mapping*, the expression list must
-   evaluate to an object whose value is one of the keys of the
-   mapping, and the subscription selects the value in the mapping that
-   corresponds to that key. An example of a builtin mapping class is
-   the "dict" class.
-
-2. Sequences. If the primary is a *sequence*, the expression list must
-   evaluate to an "int" or a "slice" (as discussed in the following
-   section). Examples of builtin sequence classes include the "str",
-   "list" and "tuple" classes.
-
-The formal syntax makes no special provision for negative indices in
-*sequences*. However, built-in sequences all provide a "__getitem__()"
-method that interprets negative indices by adding the length of the
-sequence to the index so that, for example, "x[-1]" selects the last
-item of "x". The resulting value must be a nonnegative integer less
-than the number of items in the sequence, and the subscription selects
-the item whose index is that value (counting from zero). Since the
-support for negative indices and slicing occurs in the object’s
-"__getitem__()" method, subclasses overriding this method will need to
-explicitly add that support.
-
-A "string" is a special kind of sequence whose items are *characters*.
-A character is not a separate data type but a string of exactly one
-character.
+To show how subscription works, we can define a custom object that
+implements "__getitem__()" and prints out the value of the subscript:
+
+   >>> class SubscriptionDemo:
+   ...     def __getitem__(self, key):
+   ...         print(f'subscripted with: {key!r}')
+   ...
+   >>> demo = SubscriptionDemo()
+   >>> demo[1]
+   subscripted with: 1
+   >>> demo['a' * 3]
+   subscripted with: 'aaa'
+
+See "__getitem__()" documentation for how built-in types handle
+subscription.
+
+Subscriptions may also be used as targets in assignment or deletion
+statements. In these cases, the interpreter will call the subscripted
+object’s "__setitem__()" or "__delitem__()" *special method*,
+respectively, instead of "__getitem__()".
+
+   >>> colors = ['red', 'blue', 'green', 'black']
+   >>> colors[3] = 'white'  # Setting item at index
+   >>> colors
+   ['red', 'blue', 'green', 'white']
+   >>> del colors[3]  # Deleting item at index 3
+   >>> colors
+   ['red', 'blue', 'green']
+
+All advanced forms of *subscript* documented in the following sections
+are also usable for assignment and deletion.
+
+
+Slicings
+========
+
+A more advanced form of subscription, *slicing*, is commonly used to
+extract a portion of a sequence. In this form, the subscript is a
+*slice*: up to three expressions separated by colons. Any of the
+expressions may be omitted, but a slice must contain at least one
+colon:
+
+   >>> number_names = ['zero', 'one', 'two', 'three', 'four', 'five']
+   >>> number_names[1:3]
+   ['one', 'two']
+   >>> number_names[1:]
+   ['one', 'two', 'three', 'four', 'five']
+   >>> number_names[:3]
+   ['zero', 'one', 'two']
+   >>> number_names[:]
+   ['zero', 'one', 'two', 'three', 'four', 'five']
+   >>> number_names[::2]
+   ['zero', 'two', 'four']
+   >>> number_names[:-3]
+   ['zero', 'one', 'two']
+   >>> del number_names[4:]
+   >>> number_names
+   ['zero', 'one', 'two', 'three']
+
+When a slice is evaluated, the interpreter constructs a "slice" object
+whose "start", "stop" and "step" attributes, respectively, are the
+results of the expressions between the colons. Any missing expression
+evaluates to "None". This "slice" object is then passed to the
+"__getitem__()" or "__class_getitem__()" *special method*, as above.
+
+   # continuing with the SubscriptionDemo instance defined above:
+   >>> demo[2:3]
+   subscripted with: slice(2, 3, None)
+   >>> demo[::'spam']
+   subscripted with: slice(None, None, 'spam')
+
+
+Comma-separated subscripts
+==========================
+
+The subscript can also be given as two or more comma-separated
+expressions or slices:
+
+   # continuing with the SubscriptionDemo instance defined above:
+   >>> demo[1, 2, 3]
+   subscripted with: (1, 2, 3)
+   >>> demo[1:2, 3]
+   subscripted with: (slice(1, 2, None), 3)
+
+This form is commonly used with numerical libraries for slicing multi-
+dimensional data. In this case, the interpreter constructs a "tuple"
+of the results of the expressions or slices, and passes this tuple to
+the "__getitem__()" or "__class_getitem__()" *special method*, as
+above.
+
+The subscript may also be given as a single expression or slice
+followed by a comma, to specify a one-element tuple:
+
+   >>> demo['spam',]
+   subscripted with: ('spam',)
+
+
+“Starred” subscriptions
+=======================
+
+Added in version 3.11: Expressions in *tuple_slices* may be starred.
+See **PEP 646**.
+
+The subscript can also contain a starred expression. In this case, the
+interpreter unpacks the result into a tuple, and passes this tuple to
+"__getitem__()" or "__class_getitem__()":
+
+   # continuing with the SubscriptionDemo instance defined above:
+   >>> demo[*range(10)]
+   subscripted with: (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
+
+Starred expressions may be combined with comma-separated expressions
+and slices:
+
+   >>> demo['a', 'b', *range(3), 'c']
+   subscripted with: ('a', 'b', 0, 1, 2, 'c')
+
+
+Formal subscription grammar
+===========================
+
+   subscription:     primary '[' subscript ']'
+   subscript:        single_subscript | tuple_subscript
+   single_subscript: proper_slice | assignment_expression
+   proper_slice:     [expression] ":" [expression] [ ":" [expression] ]
+   tuple_subscript:  ','.(single_subscript | starred_expression)+ [',']
+
+Recall that the "|" operator denotes ordered choice. Specifically, in

 it is also checked for site-packages (sys.base_prefix and
 sys.base_exec_prefix will always be the "real" prefixes of the Python
 installation). If "pyvenv.cfg" (a bootstrap configuration file) contains
-the key "include-system-site-packages" set to anything other than "false"
-(case-insensitive), the system-level prefixes will still also be
-searched for site-packages; otherwise they won't.
-
-All of the resulting site-specific directories, if they exist, are
-appended to sys.path, and also inspected for path configuration
-files.
-
-A path configuration file is a file whose name has the form
-<package>.pth; its contents are additional directories (one per line)
-to be added to sys.path.  Non-existing directories (or
-non-directories) are never added to sys.path; no directory is added to
-sys.path more than once.  Blank lines and lines beginning with
-'#' are skipped. Lines starting with 'import' are executed.
-
-For example, suppose sys.prefix and sys.exec_prefix are set to
-/usr/local and there is a directory /usr/local/lib/python2.5/site-packages
-with three subdirectories, foo, bar and spam, and two path
-configuration files, foo.pth and bar.pth.  Assume foo.pth contains the
-following:
-
-  # foo package configuration
-  foo
-  bar
-  bletch
-
-and bar.pth contains:
-
-  # bar package configuration
-  bar
-
-Then the following directories are added to sys.path, in this order:
-
-  /usr/local/lib/python2.5/site-packages/bar
-  /usr/local/lib/python2.5/site-packages/foo
-
-Note that bletch is omitted because it doesn't exist; bar precedes foo
-because bar.pth comes alphabetically before foo.pth; and spam is
-omitted because it is not mentioned in either path configuration file.
-
-The readline module is also automatically configured to enable
-completion for systems that support it.  This can be overridden in
-sitecustomize, usercustomize or PYTHONSTARTUP.  Starting Python in
-isolated mode (-I) disables automatic readline configuration.
-
-After these operations, an attempt is made to import a module
-named sitecustomize, which can perform arbitrary additional
-site-specific customizations.  If this import fails with an
-ImportError exception, it is silently ignored.

+Two kinds of configuration files are processed in each site-packages
+directory:
+
+- <name>.pth files extend sys.path with additional directories (one per
+  line).  Lines starting with "import" are deprecated (see PEP 829).
+
+- <name>.start files specify startup entry points using the pkg.mod:callable
+  syntax.  These are resolved via pkgutil.resolve_name() and called with no
+  arguments.

+# Reproduction for the gc.get_stats() data race under free-threading.
+#
+# CPython issue gh-151646: in free-threading builds (``--disable-gil``) the
+# concurrent collector and ``gc.get_stats()`` touch the same per-generation
+# statistics struct (``gcstate->generation_stats``) without any synchronisation:
+#
+#   * READER -- ``gc_get_stats_impl()`` in ``Modules/gcmodule.c`` copies the
+#     ``struct gc_generation_stats`` for each generation (``collections``,
+#     ``collected``, ``uncollectable``, ``candidates``, ``duration``) with a
+#     plain struct assignment and no lock.
+#
+#   * WRITER -- at the end of every collection cycle ``gc_collect_main()`` in
+#     ``Python/gc_free_threading.c`` mutates that very struct in place
+#     (``stats->collections++``, ``stats->collected += m``, ...), again with no
+#     lock.
+#
+# When one thread is collecting while several others read the stats, the
+# unsynchronised read/write to the same memory is a data race.  The values are
+# only statistics, so the race is benign at the Python level (no crash), which
+# is exactly what lets this script double as a regression test: once the fix
+# adds proper synchronisation, ThreadSanitizer should stay quiet while the
+# script keeps exiting cleanly.
+#
+# Running this script under a free-threading CPython build compiled with
+# ThreadSanitizer (``./configure --disable-gil --with-thread-sanitizer``) is
+# expected to print a ``WARNING: ThreadSanitizer: data race`` report whose stack
+# traces point at ``gc_get_stats_impl`` (gcmodule.c) and ``gc_collect_main``
+# (gc_free_threading.c).

+*  Counts number of actually tracked objects, instead of trackable objects.

+Fix cumulative percentage calculation for recursive functions in the new
+sampling profiler. When profiling recursive functions, cumulative statistics
+(cumul%, cumtime) could exceed 100% because each recursive frame in a stack
+was counted separately. For example, a function recursing 500 times in every
+sample would show 50000% cumulative presence. The fix deduplicates locations
+within each sample so cumulative stats correctly represent "percentage of
+samples where this function was on the stack". Patch by Pablo Galindo.

+Implement a limited form of register allocation known as "top of stack

+in registers. The code generator generates multiple versions of those uops
+that do not escape and are relatively small. During JIT compilation, the
+copy that produces the least memory traffic is selected, spilling or
+reloading values when needed.

+:meth:`subprocess.Popen.wait`: when ``timeout`` is not ``None``, an
+efficient event-driven mechanism now waits for process termination, if
+available. Linux >= 5.3 uses :func:`os.pidfd_open` + :func:`select.poll`.
+macOS and other BSD variants use :func:`select.kqueue` + ``KQ_FILTER_PROC``
++ ``KQ_NOTE_EXIT``. Windows keeps using ``WaitForSingleObject`` (unchanged).
+If none of these mechanisms are available, the function falls back to the
+traditional busy loop (non-blocking call and short sleeps). Patch by

+The font and wrap length of the message and the detail message are taken from

-Update the display immediately.
+Return the complex character at the given position in the window.
 
-Synchronize actual screen with previous drawing/deleting methods.
-The 6 optional arguments can only be specified when the window is a pad
-created with newpad().  The additional parameters are needed to indicate
-what part of the pad and screen are involved.  pminrow and pmincol specify
-the upper left-hand corner of the rectangle to be displayed in the pad.
-sminrow, smincol, smaxrow, and smaxcol specify the edges of the rectangle to
-be displayed on the screen.  The lower right-hand corner of the rectangle to
-be displayed in the pad is calculated from the screen coordinates, since the
-rectangles must be the same size.  Both rectangles must be entirely contained
-within their respective structures.  Negative values of pminrow, pmincol,
-sminrow, or smincol are treated as if they were zero.
+The returned object is a complexchar carrying the cell's text,
+attributes and color pair.

 About
 =====
 
@@ -7,40 +5,3 @@ _decimal.c is a wrapper for the libmpdec library. libmpdec is a fast C
 library for correctly-rounded arbitrary precision decimal floating point
 arithmetic. It is a complete implementation of Mike Cowlishaw/IBM's
 General Decimal Arithmetic Specification.
-
-
-Build process for the module
-============================
-
-As usual, the build process for _decimal.so is driven by setup.py in the top
-level directory. setup.py autodetects the following build configurations:
-
-   1) x64         - 64-bit Python, x86_64 processor (AMD, Intel)
-
-   2) uint128     - 64-bit Python, compiler provides __uint128_t (gcc)
-
-   3) ansi64      - 64-bit Python, ANSI C
-
-   4) ppro        - 32-bit Python, x86 CPU, PentiumPro or later
-
-   5) ansi32      - 32-bit Python, ANSI C
-
-   6) ansi-legacy - 32-bit Python, compiler without uint64_t
-
-   7) universal   - Mac OS only (multi-arch)
-
-
-It is possible to override autodetection by exporting:
-
-   PYTHON_DECIMAL_WITH_MACHINE=value, where value is one of the above options.
-
-
-NOTE
-====
-
-decimal.so is not built from a static libmpdec.a since doing so led to
-failures on AIX (user report) and Windows (mixing static and dynamic CRTs
-causes locale problems and more).

-libmpdec
-========
-
-libmpdec is a fast C/C++ library for correctly-rounded arbitrary precision
-decimal floating point arithmetic. It is a complete implementation of
-Mike Cowlishaw/IBM's General Decimal Arithmetic Specification.
-
-
-Files required for the Python _decimal module
-=============================================
-
-  Core files for small and medium precision arithmetic
-  ----------------------------------------------------
-
-    basearith.{c,h}  ->  Core arithmetic in base 10**9 or 10**19.
-    bits.h           ->  Portable detection of least/most significant one-bit.
-    constants.{c,h}  ->  Constants that are used in multiple files.
-    context.c        ->  Context functions.
-    io.{c,h}         ->  Conversions between mpd_t and ASCII strings,
-                         mpd_t formatting (allows UTF-8 fill character).
-    mpalloc.{c,h}    ->  Allocation handlers with overflow detection
-                         and functions for switching between static
-                         and dynamic mpd_t.
-    mpdecimal.{c,h}  ->  All (quiet) functions of the specification.
-    typearith.h      ->  Fast primitives for double word multiplication,
-                         division etc.
-
-    Visual Studio only:
-    ~~~~~~~~~~~~~~~~~~~
-      vcdiv64.asm   ->  Double word division used in typearith.h. VS 2008 does
-                        not allow inline asm for x64. Also, it does not provide
-                        an intrinsic for double word division.
-
-  Files for bignum arithmetic:
-  ----------------------------
-
-    The following files implement the Fast Number Theoretic Transform
-    used for multiplying coefficients with more than 1024 words (see
-    mpdecimal.c: _mpd_fntmul()).
-
-      umodarith.h        ->  Fast low level routines for unsigned modular arithmetic.
-      numbertheory.{c,h} ->  Routines for setting up the Number Theoretic Transform.
-      difradix2.{c,h}    ->  Decimation in frequency transform, used as the
-                             "base case" by the following three files:
-
-        fnt.{c,h}        ->  Transform arrays up to 4096 words.
-        sixstep.{c,h}    ->  Transform larger arrays of length 2**n.
-        fourstep.{c,h}   ->  Transform larger arrays of length 3 * 2**n.
-
-      convolute.{c,h}    ->  Fast convolution using one of the three transform
-                             functions.
-      transpose.{c,h}    ->  Transpositions needed for the sixstep algorithm.
-      crt.{c,h}          ->  Chinese Remainder Theorem: use information from three
-                             transforms modulo three different primes to get the
-                             final result.
-
-
-Pointers to literature, proofs and more
-=======================================
-
-  literature/
-  -----------
-
-    REFERENCES.txt  ->  List of relevant papers.
-    bignum.txt      ->  Explanation of the Fast Number Theoretic Transform (FNT).
-    fnt.py          ->  Verify constants used in the FNT; Python demo for the
-                        O(N**2) discrete transform.
-
-    matrix-transform.txt -> Proof for the Matrix Fourier Transform used in
-                            fourstep.c.
-    six-step.txt         -> Show that the algorithm used in sixstep.c is
-                            a variant of the Matrix Fourier Transform.
-    mulmod-64.txt        -> Proof for the mulmod64 algorithm from
-                            umodarith.h.
-    mulmod-ppro.txt      -> Proof for the x87 FPU modular multiplication

-
-
-The transform in a finite field can be used for convolution in the same
-way as the Fourier Transform. The main advantages of the Number Theoretic
-Transform are that it is both exact and very memory efficient.
-
-
-Convolution in pseudo-code:
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-  fnt_convolute(a, b):
-    x = fnt(a)                          # forward transform of a
-    y = fnt(b)                          # forward transform of b
-    z = pairwise multiply x[i] and y[i]
-    result = inv_fnt(z)                 # backward transform of z.
-
-
-Extending the maximum transform length (Chinese Remainder Theorem):
--------------------------------------------------------------------
-
-The maximum transform length is quite limited when using a single
-prime field. However, it is possible to use multiple primes and
-recover the result using the Chinese Remainder Theorem.
-
-
-Multiplication in pseudo-code:
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-  _mpd_fntmul(u, v):
-    c1 = fnt_convolute(u, v, P1)  # convolute modulo prime1
-    c2 = fnt_convolute(u, v, P2)  # convolute modulo prime2
-    c3 = fnt_convolute(u, v, P3)  # convolute modulo prime3
-    result = crt3(c1, c2, c3)     # Chinese Remainder Theorem
-
-
-Optimized transform functions:
-------------------------------
-
-There are three different fnt() functions:
-
-   std_fnt: "standard" decimation in frequency transform for array lengths
-            of 2**n. Performs well up to 1024 words.
-
-   sixstep: Cache-friendly algorithm for array lengths of 2**n. Outperforms
-            std_fnt for large arrays.
-
-   fourstep: Algorithm for array lengths of 3 * 2**n. Also cache friendly
-             in large parts.
-
-
-List of bignum-only files:
---------------------------
-
-Functions from these files are only used in _mpd_fntmul().
-
-  umodarith.h    -> fast low level routines for unsigned modular arithmetic
-  numbertheory.c -> routines for setting up the FNT
-  difradix2.c    -> decimation in frequency transform, used as the
-                    "base case" by the following three files:
-
-      fnt.c          -> standard transform for smaller arrays
-      sixstep.c      -> transform large arrays of length 2**n
-      fourstep.c     -> transform arrays of length 3 * 2**n
-
-  convolute.c    -> do the actual fast convolution, using one of
-                    the three transform functions.
-  transpose.c    -> transpositions needed for the sixstep algorithm.
-  crt.c          -> Chinese Remainder Theorem: use information from three
-                    transforms modulo three different primes to get the
-                    final result.

-The Matrix Fourier Transform:
-=============================
-
-In libmpdec, the Matrix Fourier Transform [1] is called four-step transform
-after a variant that appears in [2]. The algorithm requires that the input
-array can be viewed as an R*C matrix.
-
-All operations are done modulo p. For readability, the proofs drop all
-instances of (mod p).
-
-
-Algorithm four-step (forward transform):
-----------------------------------------
-
-  a := input array
-  d := len(a) = R * C
-  p := prime
-  w := primitive root of unity of the prime field
-  r := w**((p-1)/d)
-  A := output array
-
-  1) Apply a length R FNT to each column.
-
-  2) Multiply each matrix element (addressed by j*C+m) by r**(j*m).
-
-  3) Apply a length C FNT to each row.
-
-  4) Transpose the matrix.
-
-
-Proof (forward transform):
---------------------------
-
-  The algorithm can be derived starting from the regular definition of
-  the finite-field transform of length d:
-
-            d-1
-           ,----
-           \
-    A[k] =  |  a[l]  * r**(k * l)
-           /
-           `----
-           l = 0
-
-
-  The sum can be rearranged into the sum of the sums of columns:
-
-            C-1     R-1
-           ,----   ,----
-           \       \

-           `----   `----
-           j = 0   i = 0

-  Extracting a constant from the inner sum:
-
-            C-1           R-1

-  Without any loss of generality, let k = n * R + m,
-  where n < C and m < R:

-   the term for all (m, j). After that, the original matrix is now a lookup
-   table with the mth element in the jth column at location m * C + j.
-
-   Let the complete RHS be g(m, n). Step 3) does an in-place transform of
-   length n on all rows. After that, the original matrix is now a lookup
-   table with the mth element in the nth column at location m * C + n.

-Algorithm four-step (inverse transform):
-----------------------------------------
-
-  A  := input array
-  d  := len(A) = R * C
-  p  := prime
-  d' := d**(p-2)             # inverse of d

-
-  3) Multiply each matrix element (addressed by i*C+n) by r**(i*n).
-
-  4) Apply a length R FNT to each column.
-
-
-Proof (inverse transform):
---------------------------
-
-  The algorithm can be derived starting from the regular definition of
-  the finite-field inverse transform of length d:
-
-                  d-1
-                 ,----
-                 \

-                 `----
-                 l = 0
-
-
-  The sum can be rearranged into the sum of the sums of columns. Note
-  that at this stage we still have a C*R matrix, so C denotes the number
-  of rows:
-
-                  R-1     C-1
-                 ,----   ,----
-                 \       \

-                 `----   `----
-                 i = 0   j = 0
-
-
-  Extracting a constant from the inner sum:

-==========================================================================
-                Calculate (a * b) % p using special primes
-==========================================================================
-
-A description of the algorithm can be found in the apfloat manual by
-Tommila [1].
-
-
-Definitions:
-------------
-
-In the whole document, "==" stands for "is congruent with".
-
-Result of a * b in terms of high/low words:
-
-   (1) hi * 2**64 + lo = a * b
-
-Special primes:
-
-   (2) p = 2**64 - z + 1, where z = 2**n
-
-Single step modular reduction:
-
-   (3) R(hi, lo) = hi * z - hi + lo
-
-
-Strategy:
----------
-
-   a) Set (hi, lo) to the result of a * b.
-
-   b) Set (hi', lo') to the result of R(hi, lo).
-
-   c) Repeat step b) until 0 <= hi' * 2**64 + lo' < 2*p.
-
-   d) If the result is less than p, return lo'. Otherwise return lo' - p.
-
-
-The reduction step b) preserves congruence:
--------------------------------------------
-
-    hi * 2**64 + lo == hi * z - hi + lo   (mod p)
-
-    Proof:
-    ~~~~~~
-
-       hi * 2**64 + lo = (2**64 - z + 1) * hi + z * hi - hi + lo
-
-                       = p * hi               + z * hi - hi + lo
-
-                       == z * hi - hi + lo   (mod p)
-
-
-Maximum numbers of step b):
----------------------------
-
-# To avoid unnecessary formalism, define:
-
-def R(hi, lo, z):
-     return divmod(hi * z - hi + lo, 2**64)
-
-# For simplicity, assume hi=2**64-1, lo=2**64-1 after the
-# initial multiplication a * b. This is of course impossible
-# but certainly covers all cases.
-
-# Then, for p1:
-hi=2**64-1; lo=2**64-1; z=2**32
-p1 = 2**64 - z + 1
-
-hi, lo = R(hi, lo, z)    # First reduction
-hi, lo = R(hi, lo, z)    # Second reduction
-hi * 2**64 + lo < 2 * p1 # True
-
-# For p2:
-hi=2**64-1; lo=2**64-1; z=2**34
-p2 = 2**64 - z + 1
-
-hi, lo = R(hi, lo, z)    # First reduction
-hi, lo = R(hi, lo, z)    # Second reduction
-hi, lo = R(hi, lo, z)    # Third reduction
-hi * 2**64 + lo < 2 * p2 # True
-
-# For p3:
-hi=2**64-1; lo=2**64-1; z=2**40
-p3 = 2**64 - z + 1
-
-hi, lo = R(hi, lo, z)    # First reduction
-hi, lo = R(hi, lo, z)    # Second reduction
-hi, lo = R(hi, lo, z)    # Third reduction
-hi * 2**64 + lo < 2 * p3 # True
-
-
-Step d) preserves congruence and yields a result < p:
------------------------------------------------------
-
-   Case hi = 0:
-
-       Case lo < p: trivial.
-
-       Case lo >= p:
-
-          lo == lo - p   (mod p)             # result is congruent
-
-          p <= lo < 2*p  ->  0 <= lo - p < p # result is in the correct range
-
-   Case hi = 1:
-
-       p < 2**64 /\ 2**64 + lo < 2*p  ->  lo < p  # lo is always less than p
-
-       2**64 + lo == 2**64 + (lo - p)   (mod p)   # result is congruent
-
-                  = lo - p   # exactly the same value as the previous RHS
-                             # in uint64_t arithmetic.
-
-       p < 2**64 + lo < 2*p  ->  0 < 2**64 + (lo - p) < p  # correct range

-========================================================================
-             Calculate (a * b) % p using the 80-bit x87 FPU
-========================================================================
-
-A description of the algorithm can be found in the apfloat manual by
-Tommila [1].
-
-The proof follows an argument made by Granlund/Montgomery in [2].
-
-
-Definitions and assumptions:
-----------------------------
-
-The 80-bit extended precision format uses 64 bits for the significand:
-
-  (1) F = 64
-
-The modulus is prime and less than 2**31:
-
-  (2) 2 <= p < 2**31
-
-The factors are less than p:
-
-  (3) 0 <= a < p
-  (4) 0 <= b < p
-
-The product a * b is less than 2**62 and is thus exact in 64 bits:
-
-  (5) n = a * b
-
-The product can be represented in terms of quotient and remainder:
-
-  (6) n = q * p + r
-
-Using (3), (4) and the fact that p is prime, the remainder is always
-greater than zero:
-
-  (7) 0 <= q < p  /\  1 <= r < p
-
-
-Strategy:
----------
-
-Precalculate the 80-bit long double inverse of p, with a maximum
-relative error of 2**(1-F):
-
-  (8) pinv = (long double)1.0 / p
-
-Calculate an estimate for q = floor(n/p). The multiplication has another
-maximum relative error of 2**(1-F):
-
-  (9) qest = n * pinv
-
-If we can show that q < qest < q+1, then trunc(qest) = q. It is then
-easy to recover the remainder r. The complete algorithm is:
-
-  a) Set the control word to 64-bit precision and truncation mode.
-
-  b) n = a * b              # Calculate exact product.
-
-  c) qest = n * pinv        # Calculate estimate for the quotient.
-
-  d) q = (qest+2**63)-2**63 # Truncate qest to the exact quotient.
-
-  f) r = n - q * p          # Calculate remainder.
-
-
-Proof for q < qest < q+1:
--------------------------
-
-Using the cumulative error, the error bounds for qest are:
-
-                n                       n * (1 + 2**(1-F))**2
-  (9) --------------------- <= qest <=  ---------------------
-      p * (1 + 2**(1-F))**2                       p
-
-
-  Lemma 1:
-  --------
-                       n                   q * p + r
-    (10) q < --------------------- = ---------------------
-             p * (1 + 2**(1-F))**2   p * (1 + 2**(1-F))**2
-
-
-    Proof:
-    ~~~~~~
-
-    (I)     q * p * (1 + 2**(1-F))**2 < q * p + r
-
-    (II)    q * p * 2**(2-F) + q * p * 2**(2-2*F) < r
-
-    Using (1) and (7), it is sufficient to show that:
-
-    (III)   q * p * 2**(-62) + q * p * 2**(-126) < 1 <= r
-
-    (III) can easily be verified by substituting the largest possible
-    values p = 2**31-1 and q = 2**31-2.
-
-    The critical cases occur when r = 1, n = m * p + 1. These cases
-    can be exhaustively verified with a test program.
-
-
-  Lemma 2:
-  --------
-
-           n * (1 + 2**(1-F))**2     (q * p + r) * (1 + 2**(1-F))**2
-    (11)   ---------------------  =  -------------------------------  <  q + 1
-                     p                              p
-
-    Proof:
-    ~~~~~~
-
-    (I)  (q * p + r) + (q * p + r) * 2**(2-F) + (q * p + r) * 2**(2-2*F) < q * p + p
-
-    (II)  (q * p + r) * 2**(2-F) + (q * p + r) * 2**(2-2*F) < p - r
-
-    Using (1) and (7), it is sufficient to show that:
-
-    (III) (q * p + r) * 2**(-62) + (q * p + r) * 2**(-126) < 1 <= p - r
-
-    (III) can easily be verified by substituting the largest possible
-    values p = 2**31-1, q = 2**31-2 and r = 2**31-2.
-
-    The critical cases occur when r = (p - 1), n = m * p - 1. These cases

-The Six Step Transform:
-=======================
-
-In libmpdec, the six-step transform is the Matrix Fourier Transform (See
-matrix-transform.txt) in disguise. It is called six-step transform after
-a variant that appears in [1]. The algorithm requires that the input
-array can be viewed as an R*C matrix.
-
-
-Algorithm six-step (forward transform):
----------------------------------------
-
-  1a) Transpose the matrix.
-
-  1b) Apply a length R FNT to each row.
-
-  1c) Transpose the matrix.
-
-  2) Multiply each matrix element (addressed by j*C+m) by r**(j*m).
-
-  3) Apply a length C FNT to each row.
-
-  4) Transpose the matrix.
-
-Note that steps 1a) - 1c) are exactly equivalent to step 1) of the Matrix
-Fourier Transform. For large R, it is faster to transpose twice and do
-a transform on the rows than to perform a column transpose directly.
-
-
-
-Algorithm six-step (inverse transform):
----------------------------------------
-
-  0) View the matrix as a C*R matrix.
-
-  1) Transpose the matrix, producing an R*C matrix.
-
-  2) Apply a length C FNT to each row.
-
-  3) Multiply each matrix element (addressed by i*C+n) by r**(i*n).
-
-  4a) Transpose the matrix.
-
-  4b) Apply a length R FNT to each row.
-

- * A proof of the algorithm is in literature/mulmod-ppro.txt. The FPU

- * prior to using these functions.
- *
- * Algorithm: calculate (a * b) % p:
- *
- *   p    := prime < 2**31
- *   pinv := (long double)1.0 / p (precalculated)
- *
- *   a) n = a * b              # Calculate exact product.
- *   b) qest = n * pinv        # Calculate estimate for q = n / p.
- *   c) q = (qest+2**63)-2**63 # Truncate qest to the exact quotient.
- *   d) r = n - q * p          # Calculate remainder.
- *
- * Remarks:
- *
- *   - p = dmod and pinv = dinvmod.
- *   - dinvmod points to an array of three uint32_t, which is interpreted
- *     as an 80 bit long double by fldt.
- *   - Intel compilers prior to version 11 do not seem to handle the
- *     __GNUC__ inline assembly correctly.
- *   - random tests are provided in tests/extended/ppro_mulmod.c

+/*
+ * The remote debugging tables are read from the target process and must be
+ * treated as untrusted input. This header centralizes the one-time validation
+ * that runs immediately after those tables are read, before the unwinder uses
+ * any reported sizes or offsets to copy remote structs into fixed local
+ * buffers or to interpret those local copies.
+ *
+ * The key rule is simple: every offset that is later dereferenced against a
+ * local buffer or local object view must appear in one of the field lists
+ * below. Validation then checks two bounds for each field:
+ *
+ * 1. The field must fit within the section size reported by the target.
+ * 2. The same field must also fit within the local buffer or local layout the
+ *    debugger will actually use.
+ *
+ * Sections that are copied into fixed local buffers also have their reported
+ * size checked against the corresponding local buffer size up front.
+ *
+ * This is intentionally front-loaded. Once validation succeeds, the hot path
+ * can keep using the raw offsets without adding per-sample bounds checks.
+ *
+ * Maintenance rule: if either exported table grows, the static_asserts below
+ * should yell at you. When that happens, update the matching field lists in
+ * this file in the same change. And if you add a new field that the unwinder
+ * is going to poke at later, put it in the right list here too, so nobody has
+ * to rediscover this the annoying way.

+
+Initialize a new RemoteUnwinder object for debugging a remote Python process.
+
+Args:
+    pid: Process ID of the target Python process to debug
+    all_threads: If True, initialize state for all threads in the
+        process.  If False, only initialize for the main thread.
+    only_active_thread: If True, only sample the thread holding the GIL.
+    mode: Profiling mode: 0=WALL (wall-time), 1=CPU (cpu-time), 2=GIL
+        (gil-time).  Cannot be used together with all_threads=True.
+    debug: If True, chain exceptions to explain the sequence of events
+        that lead to the exception.
+    skip_non_matching_threads: If True, skip threads that don't match
+        the selected mode.  If False, include all threads regardless of
+        mode.
+    native: If True, include artificial "<native>" frames to denote
+        calls to non-Python code.
+    gc: If True, include artificial "<GC>" frames to denote active
+        garbage collection.
+    opcodes: If True, gather bytecode opcode information for
+        instruction-level profiling.
+    cache_frames: If True, enable frame caching optimization to avoid
+        re-reading unchanged parent frames between samples.
+    stats: If True, collect statistics about cache hits, memory reads,
+        etc.  Use get_stats() to retrieve the collected statistics.
+
+The RemoteUnwinder provides functionality to inspect and debug a running
+Python process, including examining thread states, stack frames and
+other runtime data.
+
+Raises:
+    PermissionError: If access to the target process is denied
+    OSError: If unable to attach to the target process or access its
+        memory
+    RuntimeError: If unable to read debug information from the target
+        process

+_remote_debugging.RemoteUnwinder.get_stack_trace
+
+Returns stack traces for all interpreters and threads in process.
+
+Each element in the returned list is a tuple of (interpreter_id,
+thread_list), where:
+- interpreter_id is the interpreter identifier
+- thread_list is a list of tuples (thread_id, frame_list) for
+  threads in that interpreter
+  - thread_id is the OS thread identifier
+  - frame_list is a list of tuples (function_name, filename,
+    line_number) representing the Python stack frames for that
+    thread, ordered from most recent to oldest
+
+The threads returned depend on the initialization parameters:
+- If only_active_thread was True: returns only the thread holding
+  the GIL across all interpreters
+- If all_threads was True: returns all threads across all
+  interpreters
+- Otherwise: returns only the main thread of each interpreter
+
+Example:
+    [
+        (0, [  # Main interpreter
+            (1234, [
+                ('process_data', 'worker.py', 127),

+        ])
+    ]
+
+Raises:
+    RuntimeError: If there is an error copying memory from the

+    OSError: If there is an error accessing the target process
+    PermissionError: If access to the target process is denied

-Initialize a new RemoteUnwinder object for debugging a remote Python process.
-
-Args:
-    pid: Process ID of the target Python process to debug
-    all_threads: If True, initialize state for all threads in the process.
-                If False, only initialize for the main thread.
-    only_active_thread: If True, only sample the thread holding the GIL.
-    mode: Profiling mode: 0=WALL (wall-time), 1=CPU (cpu-time), 2=GIL (gil-time).
-                       Cannot be used together with all_threads=True.
-    debug: If True, chain exceptions to explain the sequence of events that
-           lead to the exception.
-    skip_non_matching_threads: If True, skip threads that don't match the selected mode.
-                              If False, include all threads regardless of mode.
-
-The RemoteUnwinder provides functionality to inspect and debug a running Python
-process, including examining thread states, stack frames and other runtime data.
-
-Raises:
-    PermissionError: If access to the target process is denied
-    OSError: If unable to attach to the target process or access its memory
-    RuntimeError: If unable to read debug information from the target process
-    ValueError: If both all_threads and only_active_thread are True

-
-Returns stack traces for all interpreters and threads in process.
-
-Each element in the returned list is a tuple of (interpreter_id, thread_list), where:
-- interpreter_id is the interpreter identifier
-- thread_list is a list of tuples (thread_id, frame_list) for threads in that interpreter
-  - thread_id is the OS thread identifier
-  - frame_list is a list of tuples (function_name, filename, line_number) representing
-    the Python stack frames for that thread, ordered from most recent to oldest
-
-The threads returned depend on the initialization parameters:
-- If only_active_thread was True: returns only the thread holding the GIL across all interpreters
-- If all_threads was True: returns all threads across all interpreters
-- Otherwise: returns only the main thread of each interpreter
-
-Example:

-
-Get all tasks and their awaited_by relationships from the remote process.
-
-This provides a tree structure showing which tasks are waiting for other tasks.
-
-For each task, returns:
-1. The call stack frames leading to where the task is currently executing
-2. The name of the task
-3. A list of tasks that this task is waiting for, with their own frames/names/etc
-
-Returns a list of [frames, task_name, subtasks] where:

-- task_name: String identifier for the task
-- subtasks: List of tasks being awaited by this task, in same format
-
-Raises:

-Description of the internal format of the line number table in Python 3.10
-and earlier.
-
-(For 3.11 onwards, see InternalDocs/code_objects.md)
-
-Conceptually, the line number table consists of a sequence of triples:
-    start-offset (inclusive), end-offset (exclusive), line-number.
-
-Note that not all byte codes have a line number so we need handle `None` for the line-number.
-
-However, storing the above sequence directly would be very inefficient as we would need 12 bytes per entry.
-
-First, note that the end of one entry is the same as the start of the next, so we can overlap entries.
-Second, we don't really need arbitrary access to the sequence, so we can store deltas.
-
-We just need to store (end - start, line delta) pairs. The start offset of the first entry is always zero.
-
-Third, most deltas are small, so we can use a single byte for each value, as long we allow several entries for the same line.
-
-Consider the following table
-     Start    End     Line
-      0       6       1
-      6       50      2
-      50      350     7
-      350     360     No line number
-      360     376     8
-      376     380     208
-
-Stripping the redundant ends gives:
-
-   End-Start  Line-delta

-
-
-Note that the end - start value is always positive.
-
-Finally, in order to fit into a single byte we need to convert start deltas to the range 0 <= delta <= 254,
-and line deltas to the range -127  <= delta <= 127.
-A line delta of -128 is used to indicate no line number.
-Also note that a delta of zero indicates that there are no bytecodes in the given range,
-which means we can use an invalid line number for that range.
-
-Final form:

-    10              -128 (No line number, treated as a delta of zero)

-    0               +127 (line 135, but the range is empty as no bytecodes are at line 135)
-    4               +73
-
-Iterating over the table.
--------------------------
-
-For the `co_lines` method we want to emit the full form, omitting the (350, 360, No line number) and empty entries.
-
-The code is as follows:
-
-def co_lines(code):
-    line = code.co_firstlineno
-    end = 0
-    table_iter = iter(code.internal_line_table):
-    for sdelta, ldelta in table_iter:
-        if ldelta == 0: # No change to line number, just accumulate changes to end
-            end += sdelta
-            continue
-        start = end
-        end = start + sdelta
-        if ldelta == -128: # No valid line number -- skip entry
-            continue
-        line += ldelta
-        if end == start: # Empty range, omit.
-            continue
-        yield start, end, line
-

-
-
-The historical co_lnotab format
--------------------------------
-
-prior to 3.10 code objects stored a field named co_lnotab.
-This was an array of unsigned bytes disguised as a Python bytes object.
-
-The old co_lnotab did not account for the presence of bytecodes without a line number,
-nor was it well suited to tracing as a number of workarounds were required.
-
-The old format can still be accessed via `code.co_lnotab`, which is lazily computed from the new format.
-
-Below is the description of the old co_lnotab format:
-
-
-The array is conceptually a compressed list of
-    (bytecode offset increment, line number increment)
-pairs.  The details are important and delicate, best illustrated by example:
-
-    byte code offset    source code line number
-        0                   1
-        6                   2
-       50                   7
-      350                 207
-      361                 208
-
-Instead of storing these numbers literally, we compress the list by storing only
-the difference from one row to the next.  Conceptually, the stored list might
-look like:
-
-    0, 1,  6, 1,  44, 5,  300, 200,  11, 1
-
-The above doesn't really work, but it's a start. An unsigned byte (byte code
-offset) can't hold negative values, or values larger than 255, a signed byte
-(line number) can't hold values larger than 127 or less than -128, and the
-above example contains two such values.  (Note that before 3.6, line number
-was also encoded by an unsigned byte.)  So we make two tweaks:
-
- (a) there's a deep assumption that byte code offsets increase monotonically,
- and
- (b) if byte code offset jumps by more than 255 from one row to the next, or if
- source code line number jumps by more than 127 or less than -128 from one row
- to the next, more than one pair is written to the table. In case #b,
- there's no way to know from looking at the table later how many were written.
- That's the delicate part.  A user of co_lnotab desiring to find the source
- line number corresponding to a bytecode address A should do something like
- this:
-
-    lineno = addr = 0
-    for addr_incr, line_incr in co_lnotab:
-        addr += addr_incr
-        if addr > A:
-            return lineno
-        if line_incr >= 0x80:
-            line_incr -= 0x100
-        lineno += line_incr
-
-(In C, this is implemented by PyCode_Addr2Line().)  In order for this to work,
-when the addr field increments by more than 255, the line # increment in each
-pair generated must be 0 until the remaining addr increment is < 256.  So, in
-the example above, assemble_lnotab in compile.c should not (as was actually done
-until 2.2) expand 300, 200 to
-    255, 255, 45, 45,
-but to
-    255, 0, 45, 127, 0, 73.
-
-The above is sufficient to reconstruct line numbers for tracebacks, but not for
-line tracing.  Tracing is handled by PyCode_CheckLineNumber() in codeobject.c
-and maybe_call_line_trace() in ceval.c.
-
-*** Tracing ***
-
-To a first approximation, we want to call the tracing function when the line
-number of the current instruction changes.  Re-computing the current line for
-every instruction is a little slow, though, so each time we compute the line
-number we save the bytecode indices where it's valid:
-
-     *instr_lb <= frame->f_lasti < *instr_ub
-
-is true so long as execution does not change lines.  That is, *instr_lb holds
-the first bytecode index of the current line, and *instr_ub holds the first
-bytecode index of the next line.  As long as the above expression is true,
-maybe_call_line_trace() does not need to call PyCode_CheckLineNumber().  Note
-that the same line may appear multiple times in the lnotab, either because the
-bytecode jumped more than 255 indices between line number changes or because
-the compiler inserted the same line twice.  Even in that case, *instr_ub holds
-the first index of the next line.
-
-However, we don't *always* want to call the line trace function when the above
-test fails.
-
-Consider this code:
-
-1: def f(a):
-2:    while a:
-3:       print(1)
-4:       break
-5:    else:
-6:       print(2)
-
-which compiles to this:
-
-  2           0 SETUP_LOOP              26 (to 28)
-        >>    2 LOAD_FAST                0 (a)
-              4 POP_JUMP_IF_FALSE       18
-
-  3           6 LOAD_GLOBAL              0 (print)
-              8 LOAD_CONST               1 (1)
-             10 CALL_NO_KW               1
-             12 POP_TOP
-
-  4          14 BREAK_LOOP
-             16 JUMP_ABSOLUTE            2
-        >>   18 POP_BLOCK
-
-  6          20 LOAD_GLOBAL              0 (print)
-             22 LOAD_CONST               2 (2)
-             24 CALL_NO_KW               1
-             26 POP_TOP
-        >>   28 LOAD_CONST               0 (None)
-             30 RETURN_VALUE
-
-If 'a' is false, execution will jump to the POP_BLOCK instruction at offset 18
-and the co_lnotab will claim that execution has moved to line 4, which is wrong.
-In this case, we could instead associate the POP_BLOCK with line 5, but that
-would break jumps around loops without else clauses.
-
-We fix this by only calling the line trace function for a forward jump if the
-co_lnotab indicates we have jumped to the *start* of a line, i.e. if the current
-instruction offset matches the offset given for the start of a line by the
-co_lnotab.  For backward jumps, however, we always call the line trace function,
-which lets a debugger stop on every evaluation of a loop guard (which usually
-won't be the first opcode in a line).
-
-Why do we set f_lineno when tracing, and only just before calling the trace
-function?  Well, consider the code above when 'a' is true.  If stepping through
-this with 'n' in pdb, you would stop at line 1 with a "call" type event, then
-line events on lines 2, 3, and 4, then a "return" type event -- but because the
-code for the return actually falls in the range of the "line 6" opcodes, you
-would be shown line 6 during this event.  This is a change from the behaviour in
-2.2 and before, and I've found it confusing in practice.  By setting and using
-f_lineno when tracing, one can report a line number different from that
-suggested by f_lasti on this one occasion where it's desirable.

+# Python for Android
+
+If you obtained this README as part of a release package, then the only
+applicable sections are "Prerequisites", "Testing", and "Using in your own app".
+
+If you obtained this README as part of the CPython source tree, then you can
+also follow the other sections to compile Python for Android yourself.
+
+However, most app developers should not need to do any of these things manually.
+Instead, use one of the tools listed
+[here](https://docs.python.org/3/using/android.html), which will provide a much
+easier experience.
+
+## Prerequisites
+
+If you already have an Android SDK installed, export the `ANDROID_HOME`
+environment variable to point at its location. Otherwise, here's how to install
+it:
+
+* Download the "Command line tools" from <https://developer.android.com/studio>.
+* Create a directory `android-sdk/cmdline-tools`, and unzip the command line
+  tools package into it.
+* Rename `android-sdk/cmdline-tools/cmdline-tools` to
+  `android-sdk/cmdline-tools/latest`.
+* `export ANDROID_HOME=/path/to/android-sdk`
+
+The `Platforms/Android` script will automatically use the SDK's `sdkmanager` to install
+any packages it needs.
+
+The script also requires the following commands to be on the `PATH`:
+
+* `curl`
+* `java` (or set the `JAVA_HOME` environment variable).
+  Java versions 17 and 21 are supported.
+
+## Building
+
+Python can be built for Android on any POSIX platform supported by the Android
+development tools, which currently means Linux or macOS.
+
+First we'll make a "build" Python (for your development machine), then use it to
+help produce a "host" Python for Android. So make sure you have all the usual
+tools and libraries needed to build Python for your development machine.
+
+The easiest way to do a build is to use the `Platforms/Android` script. You can either
+have it perform the entire build process from start to finish in one step, or
+you can do it in discrete steps that mirror running `configure` and `make` for
+each of the two builds of Python you end up producing.
+
+The discrete steps for building via `Platforms/Android` are:
+
+```sh
+python3 Platforms/Android configure-build
+python3 Platforms/Android make-build
+python3 Platforms/Android configure-host HOST
+python3 Platforms/Android make-host HOST
+```
+
+`HOST` identifies which architecture to build. To see the possible values, run
+`python3 Platforms/Android configure-host --help`.
+
+To do all steps in a single command, run:
+
+```sh
+python3 Platforms/Android build HOST
+```
+In the end you should have a build Python in `cross-build/build`, and a host
+Python in `cross-build/HOST`.
+
+You can use `--` as a separator for any of the `configure`-related commands –
+including `build` itself – to pass arguments to the underlying `configure`
+call. For example, if you want a pydebug build that also caches the results from
+`configure`, you can do:
+
+```sh
+python3 Platforms/Android build HOST -- -C --with-pydebug
+```
+
+## Packaging
+
+After building an architecture as described in the section above, you can
+package it for release with this command:
+
+```sh
+python3 Platforms/Android package HOST
+```
+
+`HOST` is defined in the section above.
+
+This will generate a tarball in `cross-build/HOST/dist`, whose structure is
+similar to the `Android` directory of the CPython source tree.
+
+## Testing
+
+Tests can be run  on Linux, macOS, or Windows, using either an Android emulator
+or a physical device.
+
+On Linux, the emulator needs access to the KVM virtualization interface. This may
+require adding your user to a group, or changing your udev rules. On GitHub
+Actions, the test script will do this automatically using the commands shown
+[here](https://github.blog/changelog/2024-04-02-github-actions-hardware-accelerated-android-virtualization-now-available/).
+
+The test script supports the following modes:
+
+* In `--connected` mode, it runs on a device or emulator you have already
+  connected to the build machine. List the available devices with
+  `$ANDROID_HOME/platform-tools/adb devices -l`, then pass a device ID to the
+  script like this:
+
+  ```sh
+  python3 Platforms/Android test --connected emulator-5554
+  ```
+
+* In `--managed` mode, it uses a temporary headless emulator defined in the
+  `managedDevices` section of testbed/app/build.gradle.kts. This mode is slower,
+  but more reproducible.
+
+  We currently define two devices: `minVersion` and `maxVersion`, corresponding
+  to our minimum and maximum supported Android versions. For example:
+
+  ```sh
+  python3 Platforms/Android test --managed maxVersion
+  ```
+
+By default, the only messages the script will show are Python's own stdout and
+stderr. Add the `-v` option to also show Gradle output, and non-Python logcat
+messages.
+
+### Testing Python
+
+You can run the test suite by doing a build as described above, and then running
+`python3 Platforms/Android test`. On Windows, you won't be able to do the build
+on the same machine, so you'll have to copy the `cross-build/HOST/prefix` directory
+from somewhere else.
+
+Extra arguments on the `Platforms/Android test` command line will be passed through
+to `python -m test` – use `--` to separate them from `Platforms/Android`'s own options.
+See the [Python Developer's
+Guide](https://devguide.python.org/testing/run-write-tests/) for common options
+– most of them will work on Android, except for those that involve subprocesses,
+such as `-j`.
+
+Every time you run `python3 Platforms/Android test`, changes in pure-Python files in the
+repository's `Lib` directory will be picked up immediately. Changes in C files,
+and architecture-specific files such as sysconfigdata, will not take effect
+until you re-run `python3 Platforms/Android make-host` or `build`.
+
+### Testing a third-party package
+
+The `Platforms/Android` script is also included as `android.py` in the root of a
+release package (i.e., the one built using `Platforms/Android package`).
+
+You can use this script to test third-party packages by taking a release
+package, extracting it wherever you want, and using the `android.py` script to
+run the test suite for your third-party package.
+
+Any argument that can be passed to `python3 Platforms/Android test` can also be
+passed to `android.py`. The following options will be of particular use when
+configuring the execution of a third-party test suite:
+
+* `--cwd`: the directory of content to copy into the testbed app as the working
+  directory.
+* `--site-packages`: the directory to copy into the testbed app to use as site
+  packages.
+
+Extra arguments on the `android.py test` command line will be passed through to
+Python – use `--` to separate them from `android.py`'s own options. You must include
+either a `-c` or `-m` argument to specify how the test suite should be started.
+
+For more details, run `android.py test --help`.
+
+## Using in your own app
+
+See https://docs.python.org/3/using/android.html.

+# Apple XCframework build script
+#
+# This script simplifies the process of configuring, compiling and packaging an
+# XCframework for an Apple platform.
+#
+# At present, it only supports iOS, but it has been constructed so that it
+# could be used on any Apple platform.
+#
+# The simplest entry point is:
+#
+#   $ python Platforms/Apple ci iOS
+#
+# which will:
+# * Clean any pre-existing build artefacts
+# * Configure and make a Python that can be used for the build
+# * Configure and make a Python for each supported iOS architecture and ABI
+# * Combine the outputs of the builds from the previous step into a single
+#   XCframework, merging binaries into a "fat" binary if necessary
+# * Clone a copy of the testbed, configured to use the XCframework
+# * Construct a tarball containing the release artefacts
+# * Run the test suite using the generated XCframework.
+#
+# This is the complete sequence that would be needed in CI to build and test
+# a candidate release artefact.
+#
+# Each individual step can be invoked individually - there are commands to
+# clean, configure-build, make-build, configure-host, make-host, package, and
+# test.
+#
+# There is also a build command that can be used to combine the configure and
+# make steps for the build Python, an individual host, all hosts, or all
+# builds.

+# Python on iOS README
+
+**iOS support is [tier 3](https://peps.python.org/pep-0011/#tier-3).**
+
+This document provides a quick overview of some iOS specific features in the
+Python distribution.
+
+These instructions are only needed if you're planning to compile Python for iOS
+yourself. Most users should *not* need to do this. If you're looking to
+experiment with writing an iOS app in Python, tools such as [BeeWare's
+Briefcase](https://briefcase.readthedocs.io) and [Kivy's
+Buildozer](https://buildozer.readthedocs.io) will provide a much more
+approachable user experience.
+
+## Compilers for building on iOS
+
+Building for iOS requires the use of Apple's Xcode tooling. It is strongly
+recommended that you use the most recent stable release of Xcode. This will
+require the use of the most (or second-most) recently released macOS version,
+as Apple does not maintain Xcode for older macOS versions. The Xcode Command
+Line Tools are not sufficient for iOS development; you need a *full* Xcode
+install.
+
+If you want to run your code on the iOS simulator, you'll also need to install
+an iOS Simulator Platform. You should be prompted to select an iOS Simulator
+Platform when you first run Xcode. Alternatively, you can add an iOS Simulator
+Platform by selecting an open the Platforms tab of the Xcode Settings panel.
+
+## Building Python on iOS
+
+### ABIs and Architectures
+
+iOS apps can be deployed on physical devices, and on the iOS simulator. Although
+the API used on these devices is identical, the ABI is different - you need to
+link against different libraries for an iOS device build (`iphoneos`) or an
+iOS simulator build (`iphonesimulator`).
+
+Apple uses the `XCframework` format to allow specifying a single dependency
+that supports multiple ABIs. An `XCframework` is a wrapper around multiple
+ABI-specific frameworks that share a common API.
+
+iOS can also support different CPU architectures within each ABI. At present,
+there is only a single supported architecture on physical devices - ARM64.
+However, the *simulator* supports 2 architectures - ARM64 (for running on Apple
+Silicon machines), and x86_64 (for running on older Intel-based machines).
+
+To support multiple CPU architectures on a single platform, Apple uses a "fat
+binary" format - a single physical file that contains support for multiple
+architectures. It is possible to compile and use a "thin" single architecture
+version of a binary for testing purposes; however, the "thin" binary will not be
+portable to machines using other architectures.
+
+### Building a multi-architecture iOS XCframework
+
+The `Platforms/Apple` subfolder of the Python repository acts as a build script that
+can be used to coordinate the compilation of a complete iOS XCframework. To use
+it, run::
+
+  python Platforms/Apple build iOS
+
+This will:
+
+* Configure and compile a version of Python to run on the build machine
+* Download pre-compiled binary dependencies for each platform
+* Configure and build a `Python.framework` for each required architecture and
+  iOS SDK
+* Merge the multiple `Python.framework` folders into a single `Python.xcframework`
+* Produce a `.tar.gz` archive in the `cross-build/dist` folder containing
+  the `Python.xcframework`, plus a copy of the Testbed app pre-configured to
+  use the XCframework.
+
+The `Platforms/Apple` build script has other entry points that will perform the
+individual parts of the overall `build` target, plus targets to test the
+build, clean the `cross-build` folder of iOS build products, and perform a
+complete "build and test" CI run. The `--clean` flag can also be used on
+individual commands to ensure that a stale build product are removed before
+building.
+
+### Building a single-architecture framework
+
+If you're using the `Platforms/Apple` build script, you won't need to build
+individual frameworks. However, if you do need to manually configure an iOS
+Python build for a single framework, the following options are available.
+
+#### iOS specific arguments to configure
+
+* `--enable-framework[=DIR]`
+
+  This argument specifies the location where the Python.framework will be
+  installed. If `DIR` is not specified, the framework will be installed into
+  a subdirectory of the `iOS/Frameworks` folder.
+
+  This argument *must* be provided when configuring iOS builds. iOS does not
+  support non-framework builds.
+
+* `--with-framework-name=NAME`
+
+  Specify the name for the Python framework; defaults to `Python`.
+
+  > [!NOTE]
+  > Unless you know what you're doing, changing the name of the Python
+  > framework on iOS is not advised. If you use this option, you won't be able
+  > to run the `Platforms/Apple` build script without making significant manual
+  > alterations, and you won't be able to use any binary packages unless you
+  > compile them yourself using your own framework name.
+
+#### Building Python for iOS
+
+The Python build system will create a `Python.framework` that supports a
+*single* ABI with a *single* architecture. Unlike macOS, iOS does not allow a
+framework to contain non-library content, so the iOS build will produce a
+`bin` and `lib` folder in the same output folder as `Python.framework`.
+The `lib` folder will be needed at runtime to support the Python library.
+
+If you want to use Python in a real iOS project, you need to produce multiple
+`Python.framework` builds, one for each ABI and architecture. iOS builds of
+Python *must* be constructed as framework builds. To support this, you must
+provide the `--enable-framework` flag when configuring the build. The build
+also requires the use of cross-compilation. The minimal commands for building
+Python for the ARM64 iOS simulator will look something like:
+```
+export PATH="$(pwd)/Platforms/Apple/iOS/Resources/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin"
+./configure \
+    --enable-framework \
+    --host=arm64-apple-ios-simulator \
+    --build=arm64-apple-darwin \
+    --with-build-python=/path/to/python.exe
+make
+make install
+```
+
+In this invocation:
+
+* `Platforms/Apple/iOS/Resources/bin` has been added to the path, providing some shims for the
+  compilers and linkers needed by the build. Xcode requires the use of `xcrun`
+  to invoke compiler tooling. However, if `xcrun` is pre-evaluated and the
+  result passed to `configure`, these results can embed user- and
+  version-specific paths into the sysconfig data, which limits the portability
+  of the compiled Python. Alternatively, if `xcrun` is used *as* the compiler,
+  it requires that compiler variables like `CC` include spaces, which can
+  cause significant problems with many C configuration systems which assume that
+  `CC` will be a single executable.
+
+  To work around this problem, the `Platforms/Apple/iOS/Resources/bin` folder contains some
+  wrapper scripts that present as simple compilers and linkers, but wrap
+  underlying calls to `xcrun`. This allows configure to use a `CC`
+  definition without spaces, and without user- or version-specific paths, while
+  retaining the ability to adapt to the local Xcode install. These scripts are
+  included in the `bin` directory of an iOS install.
+
+  These scripts will, by default, use the currently active Xcode installation.
+  If you want to use a different Xcode installation, you can use
+  `xcode-select` to set a new default Xcode globally, or you can use the
+  `DEVELOPER_DIR` environment variable to specify an Xcode install. The
+  scripts will use the default `iphoneos`/`iphonesimulator` SDK version for
+  the select Xcode install; if you want to use a different SDK, you can set the
+  `IOS_SDK_VERSION` environment variable. (e.g, setting
+  `IOS_SDK_VERSION=17.1` would cause the scripts to use the `iphoneos17.1`
+  and `iphonesimulator17.1` SDKs, regardless of the Xcode default.)
+
+  The path has also been cleared of any user customizations. A common source of
+  bugs is for tools like Homebrew to accidentally leak macOS binaries into an iOS
+  build. Resetting the path to a known "bare bones" value is the easiest way to
+  avoid these problems.
+
+* `--host` is the architecture and ABI that you want to build, in GNU compiler
+  triple format. This will be one of:
+
+  - `arm64-apple-ios` for ARM64 iOS devices.
+  - `arm64-apple-ios-simulator` for the iOS simulator running on Apple
+    Silicon devices.
+  - `x86_64-apple-ios-simulator` for the iOS simulator running on Intel
+    devices.
+
+* `--build` is the GNU compiler triple for the machine that will be running
+  the compiler. This is one of:
+
+  - `arm64-apple-darwin` for Apple Silicon devices.
+  - `x86_64-apple-darwin` for Intel devices.
+
+* `/path/to/python.exe` is the path to a Python binary on the machine that
+  will be running the compiler. This is needed because the Python compilation
+  process involves running some Python code. On a normal desktop build of
+  Python, you can compile a python interpreter and then use that interpreter to
+  run Python code. However, the binaries produced for iOS won't run on macOS, so
+  you need to provide an external Python interpreter. This interpreter must be
+  the same version as the Python that is being compiled. To be completely safe,
+  this should be the *exact* same commit hash. However, the longer a Python
+  release has been stable, the more likely it is that this constraint can be
+  relaxed - the same micro version will often be sufficient.
+
+* The `install` target for iOS builds is slightly different to other
+  platforms. On most platforms, `make install` will install the build into
+  the final runtime location. This won't be the case for iOS, as the final
+  runtime location will be on a physical device.
+
+  However, you still need to run the `install` target for iOS builds, as it
+  performs some final framework assembly steps. The location specified with
+  `--enable-framework` will be the location where `make install` will
+  assemble the complete iOS framework. This completed framework can then
+  be copied and relocated as required.
+
+For a full CPython build, you also need to specify the paths to iOS builds of
+the binary libraries that CPython depends on (such as XZ, LibFFI and OpenSSL).
+This can be done by defining library specific environment variables (such as
+`LIBLZMA_CFLAGS`, `LIBLZMA_LIBS`), and the `--with-openssl` configure
+option. Versions of these libraries pre-compiled for iOS can be found in [this
+repository](https://github.com/beeware/cpython-apple-source-deps/releases).
+LibFFI is especially important, as many parts of the standard library
+(including the `platform`, `sysconfig` and `webbrowser` modules) require
+the use of the `ctypes` module at runtime.
+
+By default, Python will be compiled with an iOS deployment target (i.e., the
+minimum supported iOS version) of 13.0. To specify a different deployment
+target, provide the version number as part of the `--host` argument - for
+example, `--host=arm64-apple-ios15.4-simulator` would compile an ARM64
+simulator build with a deployment target of 15.4.
+
+## Testing Python on iOS
+
+### Testing a multi-architecture framework
+
+Once you have a built an XCframework, you can test that framework by running:
+
+  $ python Platforms/Apple test iOS
+
+This test will attempt to find an "SE-class" simulator (i.e., an iPhone SE, or
+iPhone 16e, or similar), and run the test suite on the most recent version of
+iOS that is available. You can specify a simulator using the `--simulator`
+command line argument, providing the name of the simulator (e.g., `--simulator
+'iPhone 16 Pro'`). You can also use this argument to control the OS version used
+for testing; `--simulator 'iPhone 16 Pro,OS=18.2'` would attempt to run the
+tests on an iPhone 16 Pro running iOS 18.2.
+
+If the test runner is executed on GitHub Actions, the `GITHUB_ACTIONS`
+environment variable will be exposed to the iOS process at runtime.
+
+### Testing a single-architecture framework
+
+The `Platforms/Apple/testbed` folder that contains an Xcode project that is able to run
+the Python test suite on Apple platforms. This project converts the Python test
+suite into a single test case in Xcode's XCTest framework. The single XCTest
+passes if the test suite passes.
+
+To run the test suite, configure a Python build for an iOS simulator (i.e.,
+`--host=arm64-apple-ios-simulator` or `--host=x86_64-apple-ios-simulator`
+), specifying a framework build (i.e. `--enable-framework`). Ensure that your
+`PATH` has been configured to include the `Platforms/Apple/iOS/Resources/bin` folder and
+exclude any non-iOS tools, then run:
+```
+make all
+make install
+make testios
+```
+
+This will:
+
+* Build an iOS framework for your chosen architecture;
+* Finalize the single-platform framework;
+* Make a clean copy of the testbed project;
+* Install the Python iOS framework into the copy of the testbed project; and
+* Run the test suite on an "entry-level device" simulator (i.e., an iPhone SE,
+  iPhone 16e, or a similar).
+
+On success, the test suite will exit and report successful completion of the
+test suite. On a 2022 M1 MacBook Pro, the test suite takes approximately 15
+minutes to run; a couple of extra minutes is required to compile the testbed
+project, and then boot and prepare the iOS simulator.
+
+### Debugging test failures
+
+Running `python Platforms/Apple test iOS` generates a standalone version of the
+`Platforms/Apple/testbed` project, and runs the full test suite. It does this using
+`Platforms/Apple/testbed` itself - the folder is an executable module that can be used
+to create and run a clone of the testbed project. The standalone version of the
+testbed will be created in a directory named
+`cross-build/iOS-testbed.<timestamp>`.
+
+You can generate your own standalone testbed instance by running:
+```
+python cross-build/iOS/testbed clone my-testbed
+```
+
+In this invocation, `my-testbed` is the name of the folder for the new
+testbed clone.
+
+If you've built your own XCframework, or you only want to test a single architecture,
+you can construct a standalone testbed instance by running:
+```
+python Platforms/Apple/testbed clone --platform iOS --framework <path/to/framework> my-testbed
+```
+
+The framework path can be the path path to a `Python.xcframework`, or the
+path to a folder that contains a single-platform `Python.framework`.
+
+You can then use the `my-testbed` folder to run the Python test suite,
+passing in any command line arguments you may require. For example, if you're
+trying to diagnose a failure in the `os` module, you might run:
+```
+python my-testbed run -- test -W test_os
+```
+
+This is the equivalent of running `python -m test -W test_os` on a desktop
+Python build. Any arguments after the `--` will be passed to testbed as if
+they were arguments to `python -m` on a desktop machine.
+
+### Testing in Xcode
+
+You can also open the testbed project in Xcode by running:
+```
+open my-testbed/iOSTestbed.xcodeproj
+```
+
+This will allow you to use the full Xcode suite of tools for debugging.
+
+The arguments used to run the test suite are defined as part of the test plan.
+To modify the test plan, select the test plan node of the project tree (it
+should be the first child of the root node), and select the "Configurations"
+tab. Modify the "Arguments Passed On Launch" value to change the testing
+arguments.
+
+The test plan also disables parallel testing, and specifies the use of the
+`Testbed.lldbinit` file for providing configuration of the debugger. The
+default debugger configuration disables automatic breakpoints on the
+`SIGINT`, `SIGUSR1`, `SIGUSR2`, and `SIGXFSZ` signals.
+
+### Testing on an iOS device
+
+To test on an iOS device, the app needs to be signed with known developer
+credentials. To obtain these credentials, you must have an iOS Developer
+account, and your Xcode install will need to be logged into your account (see
+the Accounts tab of the Preferences dialog).
+
+Once the project is open, and you're signed into your Apple Developer account,
+select the root node of the project tree (labeled "iOSTestbed"), then the
+"Signing & Capabilities" tab in the details page. Select a development team
+(this will likely be your own name), and plug in a physical device to your
+macOS machine with a USB cable. You should then be able to select your physical
+device from the list of targets in the pulldown in the Xcode titlebar.

+# Python WASI (wasm32-wasi) build
+
+**WASI support is [tier 2](https://peps.python.org/pep-0011/#tier-2).**
+
+This directory contains configuration and helpers to facilitate cross
+compilation of CPython to WebAssembly (WASM) using WASI. WASI builds
+use WASM runtimes such as [wasmtime](https://wasmtime.dev/).
+
+**NOTE**: If you are looking for general information about WebAssembly that is
+not directly related to CPython, please see https://github.com/psf/webassembly.
+
+## Build
+
+See [the devguide on how to build and run for WASI](https://devguide.python.org/getting-started/setup-building/#wasi).
+
+## Detecting WASI builds
+
+### Python code
+
+```python
+import os, sys
+
+if sys.platform == "wasi":
+    # Python on WASI
+    ...
+
+if os.name == "posix":
+    # WASM platforms identify as POSIX-like.
+    # Windows does not provide os.uname().
+    machine = os.uname().machine
+    if machine.startswith("wasm"):
+        # WebAssembly (wasm32, wasm64 potentially in the future)
+```
+
+```python
+>>> import os, sys
+>>> os.uname()
+posix.uname_result(
+    sysname='wasi',
+    nodename='(none)',
+    release='0.0.0',
+    version='0.0.0',
+    machine='wasm32'
+)
+>>> os.name
+'posix'
+>>> sys.platform
+'wasi'
+```
+
+### C code
+
+WASI SDK defines several built-in macros. You can dump a full list of built-ins
+with ``/path/to/wasi-sdk/bin/clang -dM -E - < /dev/null``.
+
+* WebAssembly ``__wasm__`` (also ``__wasm``)
+* wasm32 ``__wasm32__`` (also ``__wasm32``)
+* wasm64 ``__wasm64__``
+* WASI ``__wasi__``

+# Python Emscripten (wasm32-emscripten) build
+
+**Emscripten support is [tier 3](https://peps.python.org/pep-0011/#tier-3).**
+
+This directory contains configuration and helpers to facilitate cross
+compilation of CPython to WebAssembly (WASM) using Emscripten. Emscripten builds
+run in modern browsers and JavaScript runtimes like *Node.js*.
+
+For WASI builds, see [Platforms/WASI](../../Platforms/WASI/README.md).
+
+**NOTE**: If you are looking for general information about WebAssembly that is
+not directly related to CPython, please see https://github.com/psf/webassembly.
+
+### Build
+
+See [the devguide instructions for building for Emscripten](https://devguide.python.org/getting-started/setup-building/#emscripten).
+
+### Running from node
+
+If you want to run the normal Python CLI, you can use `python.sh`. It takes the
+same options as the normal Python CLI entrypoint, though the REPL does not
+function and will crash.
+
+`python.sh` invokes `node_entry.mjs` which imports the Emscripten module for the
+Python process and starts it up with the appropriate settings. If you wish to
+make a node application that "embeds" the interpreter instead of acting like the
+CLI you will need to write your own alternative to `node_entry.mjs`.
+
+
+### Running tests
+
+After building, you can run the full test suite with:
+```shell
+./cross-build/wasm32-emscripten/build/python/python.sh -m test -uall
+```
+You can run the browser smoke test with:
+```shell
+./Platforms/emscripten/browser_test/run_test.sh
+```
+
+### The Web Example
+
+When building for Emscripten, a small web example will be built automatically
+in the ``web_example`` directory. To run the web example, ``cd`` into the
+``web_example`` directory, then run ``python server.py``. This will start a web
+server; you can then visit ``http://localhost:8000/`` in a browser to see a
+simple REPL example.
+
+The web example relies on a bug fix in Emscripten version 3.1.73 so if you build
+with earlier versions of Emscripten it may not work. The web example uses
+``SharedArrayBuffer``. For security reasons browsers only provide
+``SharedArrayBuffer`` in secure environments with cross-origin isolation. The
+webserver must send cross-origin headers and correct MIME types for the
+JavaScript and WebAssembly files. Otherwise the terminal will fail to load with
+an error message like ``ReferenceError: SharedArrayBuffer is not defined``. See
+more information here:
+https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer#security_requirements
+
+Note that ``SharedArrayBuffer`` is _not required_ to use Python itself, only the
+web example. If cross-origin isolation is not appropriate for your use case you
+may make your own application embedding `python.mjs` which does not use
+``SharedArrayBuffer`` and serve it without the cross-origin isolation headers.
+
+### Embedding Python in a custom JavaScript application
+
+You can look at `python.worker.mjs` and `node_entry.mjs` for inspiration. At a
+minimum you must import ``createEmscriptenModule`` and you need to call
+``createEmscriptenModule`` with an appropriate settings object. This settings
+object will need a prerun hook that installs the Python standard library into
+the Emscripten file system.
+
+#### NodeJs
+
+In Node, you can use the NodeFS to mount the standard library in your native
+file system into the Emscripten file system:
+```js
+import createEmscriptenModule from "./python.mjs";
+
+await createEmscriptenModule({
+    preRun(Module) {
+        Module.FS.mount(
+            Module.FS.filesystems.NODEFS,
+            { root: "/path/to/python/stdlib" },
+            "/lib/",
+        );
+    },
+});
+```
+
+#### Browser
+
+In the browser, the simplest approach is to put the standard library in a zip
+file it and install it. With Python 3.14 this could look like:
+```js
+import createEmscriptenModule from "./python.mjs";
+
+await createEmscriptenModule({
+  async preRun(Module) {
+    Module.FS.mkdirTree("/lib/python3.14/lib-dynload/");
+    Module.addRunDependency("install-stdlib");
+    const resp = await fetch("python3.14.zip");
+    const stdlibBuffer = await resp.arrayBuffer();
+    Module.FS.writeFile(`/lib/python314.zip`, new Uint8Array(stdlibBuffer), {
+      canOwn: true,
+    });
+    Module.removeRunDependency("install-stdlib");
+  },
+});
+```
+
+### Limitations and issues
+
+#### Network stack
+
+- Python's socket module does not work with Emscripten's emulated POSIX
+  sockets yet. Network modules like ``asyncio``, ``urllib``, ``selectors``,
+  etc. are not available.
+- Only ``AF_INET`` and ``AF_INET6`` with ``SOCK_STREAM`` (TCP) or
+  ``SOCK_DGRAM`` (UDP) are available. ``AF_UNIX`` is not supported.
+- ``socketpair`` does not work.
+- Blocking sockets are not available and non-blocking sockets don't work
+  correctly, e.g. ``socket.accept`` crashes the runtime. ``gethostbyname``
+  does not resolve to a real IP address. IPv6 is not available.
+- The ``select`` module is limited. ``select.select()`` crashes the runtime
+  due to lack of exectfd support.
+
+#### processes, signals
+
+- Processes are not supported. System calls like fork, popen, and subprocess
+  fail with ``ENOSYS`` or ``ENOSUP``.
+- Signal support is limited. ``signal.alarm``, ``itimer``, ``sigaction``
+  are not available or do not work correctly. ``SIGTERM`` exits the runtime.
+- Keyboard interrupt (CTRL+C) handling is not implemented yet.
+- Resource-related functions like ``os.nice`` and most functions of the
+  ``resource`` module are not available.
+
+#### threading
+
+- Threading is disabled by default. The ``configure`` option
+  ``--enable-wasm-pthreads`` adds compiler flag ``-pthread`` and
+  linker flags ``-sUSE_PTHREADS -sPROXY_TO_PTHREAD``.
+- pthread support requires WASM threads and SharedArrayBuffer (bulk memory).
+  The Node.JS runtime keeps a pool of web workers around. Each web worker
+  uses several file descriptors (eventfd, epoll, pipe).
+- It's not advised to enable threading when building for browsers or with
+  dynamic linking support; there are performance and stability issues.
+
+#### file system
+
+- Most user, group, and permission related function and modules are not
+  supported or don't work as expected, e.g.``pwd`` module, ``grp`` module,
+  ``os.setgroups``, ``os.chown``, and so on. ``lchown`` and ``lchmod`` are
+  not available.
+- ``umask`` is a no-op.
+- hard links (``os.link``) are not supported.
+- Offset and iovec I/O functions (e.g. ``os.pread``, ``os.preadv``) are not
+  available.
+- ``os.mknod`` and ``os.mkfifo``
+  [don't work](https://github.com/emscripten-core/emscripten/issues/16158)
+  and are disabled.
+- Large file support crashes the runtime and is disabled.
+- ``mmap`` module is unstable. flush (``msync``) can crash the runtime.
+
+#### Misc
+
+- Heap memory and stack size are limited. Recursion or extensive memory
+  consumption can crash Python.
+- Most stdlib modules with a dependency on external libraries are missing,
+  e.g. ``ctypes``, ``readline``, ``ssl``, and more.
+- Shared extension modules are not implemented yet. All extension modules
+  are statically linked into the main binary. The experimental configure
+  option ``--enable-wasm-dynamic-linking`` enables dynamic extension
+  support. It's currently known to crash in combination with threading.
+- glibc extensions for date and time formatting are not available.
+- ``locales`` module is affected by musl libc issues,
+  [gh-90548](https://github.com/python/cpython/issues/90548).
+- Python's object allocator ``obmalloc`` is disabled by default.
+- ``ensurepip`` is not available.
+
+#### In the browser
+
+- The interactive shell does not handle copy 'n paste and unicode support
+  well.
+- The bundled stdlib is limited. Network-related modules,
+  multiprocessing, dbm, tests and similar modules
+  are not shipped. All other modules are bundled as pre-compiled
+  ``pyc`` files.
+- In-memory file system (MEMFS) is not persistent and limited.
+- Test modules are built by default. Use ``--disable-test-modules`` to disable
+  building test modules like ``_testcapi``.

+## Detecting Emscripten builds
+
+### Python code
+
+```python
+import os, sys
+
+if sys.platform == "emscripten":
+    # Python on Emscripten
+    ...
+
+if os.name == "posix":
+    # WASM platforms identify as POSIX-like.
+    # Windows does not provide os.uname().
+    machine = os.uname().machine
+    if machine.startswith("wasm"):
+        # WebAssembly (wasm32, wasm64 potentially in the future)
+```
+
+```python
+>>> import os, sys
+>>> os.uname()
+posix.uname_result(
+    sysname='Emscripten',
+    nodename='emscripten',
+    release='4.0.2',
+    version='#1',
+    machine='wasm32'
+)
+>>> os.name
+'posix'
+>>> sys.platform
+'emscripten'
+>>> sys._emscripten_info
+sys._emscripten_info(
+    emscripten_version=(3, 1, 10),
+    runtime='Mozilla/5.0 (X11; Linux x86_64; rv:104.0) Gecko/20100101 Firefox/104.0',
+    pthreads=False,
+    shared_memory=False
+)
+```
+
+```python
+>>> sys._emscripten_info
+sys._emscripten_info(
+    emscripten_version=(3, 1, 19),
+    runtime='Node.js v14.18.2',
+    pthreads=True,
+    shared_memory=True
+)
+```
+
+### C code
+
+Emscripten SDK defines several built-in macros. You can dump a full list of
+built-ins with ``emcc -dM -E - < /dev/null``.
+
+* WebAssembly ``__wasm__`` (also ``__wasm``)
+* wasm32 ``__wasm32__`` (also ``__wasm32``)
+* wasm64 ``__wasm64__``
+* Emscripten ``__EMSCRIPTEN__`` (also ``EMSCRIPTEN``)
+* Emscripten version ``__EMSCRIPTEN_major__``, ``__EMSCRIPTEN_minor__``, ``__EMSCRIPTEN_tiny__``

+/**
+ * This is a pared down version of
+ * https://github.com/pyodide/pyodide/blob/main/src/js/streams.ts
+ *
+ * It replaces the standard streams devices that Emscripten provides with our
+ * own better ones. It fixes the following deficiencies:
+ *
+ * 1. The emscripten std streams always have isatty set to true. These set
+ *    isatty to match the value for the stdin/stdout/stderr that node sees.
+ * 2. The emscripten std streams don't support the ttygetwinsize ioctl. If
+ *    isatty() returns true, then these do, and it returns the actual window
+ *    size as the OS reports it to Node.
+ * 3. The emscripten std streams introduce an extra layer of buffering which has
+ *    to be flushed with fsync().
+ * 4. The emscripten std streams are slow and complex because they go through a
+ *    character-based handler layer. This is particularly awkward because both
+ *    sides of this character based layer deal with buffers and so we need
+ *    complex adaptors, buffering, etc on both sides. Removing this
+ *    character-based middle layer makes everything better.
+ *    https://github.com/emscripten-core/emscripten/blob/1aa7fb531f11e11e7ae49b75a24e1a8fe6fa4a7d/src/lib/libtty.js?plain=1#L104-L114
+ *
+ * Ideally some version of this should go upstream to Emscripten since it is not
+ * in any way specific to Python. But I (Hood) haven't gotten around to it yet.

+// We use the _PyRuntime.emscripten_trampoline field to store a function pointer
+// for a wasm-gc based trampoline if it works. Otherwise fall back to JS
+// trampoline. The JS trampoline breaks stack switching but every runtime that
+// supports stack switching also supports wasm-gc.
+//
+// We'd like to make the trampoline call into a direct call but currently we
+// need to import the wasmTable to compile trampolineModule. emcc >= 4.0.19
+// defines the table in WebAssembly and exports it so we won't have access to it
+// until after the main module is compiled.
+//
+// To fix this, one natural solution would be to pass a funcref to the
+// trampoline instead of a table index. Several PRs would be needed to fix
+// things in llvm and emscripten in order to make this possible.
+//
+// The performance costs of an extra call_indirect aren't that large anyways.
+// The JIT should notice that the target is always the same and turn into a
+// check
+//
+// if (call_target != expected) deoptimize;
+// direct_call(call_target, args);
+
+// Offset of emscripten_trampoline in _PyRuntimeState. There's a couple of
+// alternatives:
+//
+// 1. Just make emscripten_trampoline a real C global variable instead of a
+//    field of _PyRuntimeState. This would violate our rule against mutable
+//    globals.
+//
+// 2. #define a preprocessor constant equal to a hard coded number and make a
+//    _Static_assert(offsetof(_PyRuntimeState, emscripten_trampoline) == OURCONSTANT)
+//    This has the disadvantage that we have to update the hard coded constant
+//    when _PyRuntimeState changes

+               of tracked objects (see also issue #4074):
+
+               To limit the cost of garbage collection, there are two strategies;
+                 - make each collection faster, e.g. by scanning fewer objects
+                 - do less collections
+               This heuristic is about the latter strategy.
+
+               In addition to the various configurable thresholds, we only trigger a
+               full collection if the ratio
+
+                long_lived_pending / long_lived_total
+
+               is above a given value (hardwired to 25%).
+
+               The reason is that, while "non-full" collections (i.e., collections of
+               the young and middle generations) will always examine roughly the same
+               number of objects -- determined by the aforementioned thresholds --,
+               the cost of a full collection is proportional to the total number of
+               long-lived objects, which is virtually unbounded.
+
+               Indeed, it has been remarked that doing a full collection every
+               <constant number> of object creations entails a dramatic performance
+               degradation in workloads which consist in creating and storing lots of
+               long-lived objects (e.g. building a large list of GC-tracked objects would
+               show quadratic performance, instead of linear as expected: see issue #4074).
+
+               Using the above ratio, instead, yields amortized linear performance in
+               the total number of objects (the effect of which can be summarized
+               thusly: "each full garbage collection is more and more costly as the
+               number of objects grows, but we do fewer and fewer of them").
+
+               This heuristic was suggested by Martin von Löwis on python-dev in
+               June 2008. His original analysis and proposal can be found at:

+    * DWARF Unwind Table for Trampoline Function
+    *
+    * This section defines DWARF Call Frame Information (CFI) using encoded macros

+    * preserves and restores registers. This is used by profiling tools (e.g., `perf`)

+    *
+    * -------------------------------------------------
+    * TO REGENERATE THIS TABLE FROM GCC OBJECTS:
+    * -------------------------------------------------
+    *
+    * 1. Create a trampoline source file (e.g., `trampoline.c`):
+    *
+    *      #include <Python.h>
+    *      typedef PyObject* (*py_evaluator)(void*, void*, int);
+    *      PyObject* trampoline(void *ts, void *f, int throwflag, py_evaluator evaluator) {
+    *          return evaluator(ts, f, throwflag);
+    *      }
+    *
+    * 2. Compile to an object file with frame pointer preservation:
+    *
+    *      gcc trampoline.c -I. -I./Include -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -c
+    *
+    * 3. Extract DWARF unwind info from the object file:
+    *
+    *      readelf -w trampoline.o
+    *
+    *    Example output from `.eh_frame`:
+    *
+    *      00000000 CIE
+    *        Version:               1
+    *        Augmentation:          "zR"
+    *        Code alignment factor: 4
+    *        Data alignment factor: -8
+    *        Return address column: 30
+    *        DW_CFA_def_cfa: r31 (sp) ofs 0
+    *

+    *        DW_CFA_restore: r29

+    *
+    * -- These values can be verified by comparing with `readelf -w` or `llvm-dwarfdump --eh-frame`.
+    *
+    * ----------------------------------
+    * HOW TO TRANSLATE TO DWRF_* MACROS:
+    * ----------------------------------
+    *
+    * After compiling your trampoline with:
+    *
+    *     gcc trampoline.c -I. -I./Include -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -c
+    *
+    * run:
+    *
+    *     readelf -w trampoline.o
+    *
+    * to inspect the generated `.eh_frame` data. You will see two main components:
+    *
+    *     1. A CIE (Common Information Entry): shared configuration used by all FDEs.
+    *     2. An FDE (Frame Description Entry): function-specific unwind instructions.
+    *
+    * ---------------------
+    * Translating the CIE:
+    * ---------------------
+    * From `readelf -w`, you might see:
+    *
+    *   00000000 0000000000000010 00000000 CIE
+    *     Version:               1

+    *     Code alignment factor: 4
+    *     Data alignment factor: -8
+    *     Return address column: 30
+    *     Augmentation data:     1b
+    *     DW_CFA_def_cfa: r31 (sp) ofs 0
+    *
+    * Map this to:

+    *         DWRF_UV(1);                             // Augmentation data length = 1
+    *         DWRF_U8(DWRF_EH_PE_pcrel | DWRF_EH_PE_sdata4); // Encoding for FDE pointers
+    *
+    *         DWRF_U8(DWRF_CFA_def_cfa);              // DW_CFA_def_cfa
+    *         DWRF_UV(DWRF_REG_SP);                   // Register: SP (r31)
+    *         DWRF_UV(0);                             // Offset = 0

+    *         DWRF_ALIGNNOP(sizeof(uintptr_t));       // Align to pointer size boundary
+    *     )
+    *
+    * Notes:
+    *   - Use `DWRF_UV` for unsigned LEB128, `DWRF_SV` for signed LEB128.
+    *   - `DWRF_REG_RA` and `DWRF_REG_SP` are architecture-defined constants.

+    *      the code is in a different address space every time.
+    *   3. For each `DW_CFA_*` entry, use the corresponding `DWRF_*` macro:
+    *        - `DW_CFA_def_cfa_offset`     → DWRF_U8(DWRF_CFA_def_cfa_offset), DWRF_UV(value)
+    *        - `DW_CFA_offset: rX`         → DWRF_U8(DWRF_CFA_offset | reg), DWRF_UV(offset)
+    *        - `DW_CFA_restore: rX`        → DWRF_U8(DWRF_CFA_offset | reg) // restore is same as reusing offset
+    *        - `DW_CFA_advance_loc: N`     → DWRF_U8(DWRF_CFA_advance_loc | (N / code_alignment_factor))
+    *   4. Use `DWRF_REG_FP`, `DWRF_REG_RA`, etc., for register numbers.

-    * DWARF Unwind Table for Trampoline Function
-    *
-    * This section defines DWARF Call Frame Information (CFI) using encoded macros
-    * like `DWRF_U8`, `DWRF_UV`, and `DWRF_SECTION` to describe how the trampoline function
-    * preserves and restores registers. This is used by profiling tools (e.g., `perf`)
-    * and debuggers for stack unwinding in JIT-compiled code.
-    *
-    * -------------------------------------------------
-    * TO REGENERATE THIS TABLE FROM GCC OBJECTS:
-    * -------------------------------------------------
-    *
-    * 1. Create a trampoline source file (e.g., `trampoline.c`):
-    *
-    *      #include <Python.h>
-    *      typedef PyObject* (*py_evaluator)(void*, void*, int);
-    *      PyObject* trampoline(void *ts, void *f, int throwflag, py_evaluator evaluator) {
-    *          return evaluator(ts, f, throwflag);
-    *      }
-    *
-    * 2. Compile to an object file with frame pointer preservation:
-    *
-    *      gcc trampoline.c -I. -I./Include -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -c
-    *
-    * 3. Extract DWARF unwind info from the object file:
-    *
-    *      readelf -w trampoline.o
-    *
-    *    Example output from `.eh_frame`:
-    *
-    *      00000000 CIE
-    *        Version:               1
-    *        Augmentation:          "zR"
-    *        Code alignment factor: 4
-    *        Data alignment factor: -8
-    *        Return address column: 30
-    *        DW_CFA_def_cfa: r31 (sp) ofs 0
-    *
-    *      00000014 FDE cie=00000000 pc=0..14
-    *        DW_CFA_advance_loc: 4
-    *        DW_CFA_def_cfa_offset: 16
-    *        DW_CFA_offset: r29 at cfa-16
-    *        DW_CFA_offset: r30 at cfa-8
-    *        DW_CFA_advance_loc: 12
-    *        DW_CFA_restore: r30
-    *        DW_CFA_restore: r29
-    *        DW_CFA_def_cfa_offset: 0
-    *
-    * -- These values can be verified by comparing with `readelf -w` or `llvm-dwarfdump --eh-frame`.
-    *
-    * ----------------------------------
-    * HOW TO TRANSLATE TO DWRF_* MACROS:
-    * ----------------------------------
-    *
-    * After compiling your trampoline with:
-    *
-    *     gcc trampoline.c -I. -I./Include -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -c
-    *
-    * run:
-    *
-    *     readelf -w trampoline.o
-    *
-    * to inspect the generated `.eh_frame` data. You will see two main components:
-    *
-    *     1. A CIE (Common Information Entry): shared configuration used by all FDEs.
-    *     2. An FDE (Frame Description Entry): function-specific unwind instructions.
-    *
-    * ---------------------
-    * Translating the CIE:
-    * ---------------------
-    * From `readelf -w`, you might see:
-    *
-    *   00000000 0000000000000010 00000000 CIE
-    *     Version:               1
-    *     Augmentation:          "zR"
-    *     Code alignment factor: 4
-    *     Data alignment factor: -8
-    *     Return address column: 30
-    *     Augmentation data:     1b
-    *     DW_CFA_def_cfa: r31 (sp) ofs 0
-    *
-    * Map this to:
-    *
-    *     DWRF_SECTION(CIE,
-    *         DWRF_U32(0);                             // CIE ID (always 0 for CIEs)
-    *         DWRF_U8(DWRF_CIE_VERSION);              // Version: 1
-    *         DWRF_STR("zR");                         // Augmentation string "zR"
-    *         DWRF_UV(4);                             // Code alignment factor = 4
-    *         DWRF_SV(-8);                            // Data alignment factor = -8
-    *         DWRF_U8(DWRF_REG_RA);                   // Return address register (e.g., x30 = 30)
-    *         DWRF_UV(1);                             // Augmentation data length = 1
-    *         DWRF_U8(DWRF_EH_PE_pcrel | DWRF_EH_PE_sdata4); // Encoding for FDE pointers
-    *
-    *         DWRF_U8(DWRF_CFA_def_cfa);              // DW_CFA_def_cfa
-    *         DWRF_UV(DWRF_REG_SP);                   // Register: SP (r31)
-    *         DWRF_UV(0);                             // Offset = 0
-    *
-    *         DWRF_ALIGNNOP(sizeof(uintptr_t));       // Align to pointer size boundary
-    *     )
-    *
-    * Notes:
-    *   - Use `DWRF_UV` for unsigned LEB128, `DWRF_SV` for signed LEB128.
-    *   - `DWRF_REG_RA` and `DWRF_REG_SP` are architecture-defined constants.
-    *
-    * ---------------------
-    * Translating the FDE:
-    * ---------------------
-    * From `readelf -w`:
-    *
-    *   00000014 0000000000000020 00000018 FDE cie=00000000 pc=0000000000000000..0000000000000014

-    *     DW_CFA_restore: r30
-    *     DW_CFA_restore: r29
-    *     DW_CFA_def_cfa_offset: 0
-    *
-    * Map the FDE header and instructions to:
-    *
-    *     DWRF_SECTION(FDE,
-    *         DWRF_U32((uint32_t)(p - framep));       // Offset to CIE (relative from here)
-    *         DWRF_U32(pc_relative_offset);           // PC-relative location of the code (calculated dynamically)
-    *         DWRF_U32(ctx->code_size);               // Code range covered by this FDE
-    *         DWRF_U8(0);                             // Augmentation data length (none)
-    *
-    *         DWRF_U8(DWRF_CFA_advance_loc | 1);      // Advance location by 1 unit (1 * 4 = 4 bytes)
-    *         DWRF_U8(DWRF_CFA_def_cfa_offset);       // CFA = SP + 16
-    *         DWRF_UV(16);
-    *
-    *         DWRF_U8(DWRF_CFA_offset | DWRF_REG_FP); // Save x29 (frame pointer)
-    *         DWRF_UV(2);                             // At offset 2 * 8 = 16 bytes
-    *
-    *         DWRF_U8(DWRF_CFA_offset | DWRF_REG_RA); // Save x30 (return address)
-    *         DWRF_UV(1);                             // At offset 1 * 8 = 8 bytes
-    *
-    *         DWRF_U8(DWRF_CFA_advance_loc | 3);      // Advance location by 3 units (3 * 4 = 12 bytes)
-    *
-    *         DWRF_U8(DWRF_CFA_offset | DWRF_REG_RA); // Restore x30

-    *         DWRF_UV(0);
-    *     )
-    *
-    * To regenerate:
-    *   1. Get the `code alignment factor`, `data alignment factor`, and `RA column` from the CIE.
-    *   2. Note the range of the function from the FDE's `pc=...` line and map it to the JIT code as
-    *      the code is in a different address space every time.
-    *   3. For each `DW_CFA_*` entry, use the corresponding `DWRF_*` macro:
-    *        - `DW_CFA_def_cfa_offset`     → DWRF_U8(DWRF_CFA_def_cfa_offset), DWRF_UV(value)
-    *        - `DW_CFA_offset: rX`         → DWRF_U8(DWRF_CFA_offset | reg), DWRF_UV(offset)
-    *        - `DW_CFA_restore: rX`        → DWRF_U8(DWRF_CFA_offset | reg) // restore is same as reusing offset
-    *        - `DW_CFA_advance_loc: N`     → DWRF_U8(DWRF_CFA_advance_loc | (N / code_alignment_factor))
-    *   4. Use `DWRF_REG_FP`, `DWRF_REG_RA`, etc., for register numbers.
-    *   5. Use `sizeof(uintptr_t)` (typically 8) for pointer size calculations and alignment.

 To update the LLVM release artifact for Windows builds, follow these steps:
 1. Go to the [LLVM releases page](https://github.com/llvm/llvm-project/releases).
-1. Download x86_64 Windows artifact for the desired LLVM version (e.g. `clang+llvm-21.1.4-x86_64-pc-windows-msvc.tar.xz`).

+1. Extract and repackage each tarball with the correct directory structure. For example:
    ```bash
+   # For x86_64 (AMD64)
    tar -xf clang+llvm-21.1.4-x86_64-pc-windows-msvc.tar.xz
    mv clang+llvm-21.1.4-x86_64-pc-windows-msvc llvm-21.1.4.0

-1. Create a new release with the updated LLVM artifact.
+1. Create a new release with the LLVM artifacts.
     - Create a new tag to match the LLVM version (e.g. `llvm-21.1.4.0`).
-    - Specify the release title (e.g. `LLVM 21.1.4 for x86_64 Windows`).
-    - Upload the asset (you can leave all other fields the same).
+    - Specify the release title (e.g. `LLVM 21.1.4`).
+    - Upload both platform-specific assets to the same release.
 
 ### Other notes
 - You must make sure that the name of the artifact matches exactly what is expected in `Tools/jit/_llvm.py` and `PCbuild/get_externals.py`.
-- We don't need multiple release artifacts for each architecture because LLVM can cross-compile for different architectures on Windows; x86_64 is sufficient.
+- The artifact filename must include the architecture suffix (e.g. `llvm-21.1.4.0-x64.tar.xz`, `llvm-21.1.4.0-ARM64.tar.xz`).
 - You must have permissions to create releases in the `cpython-bin-deps` repository. If you don't have permissions, you should contact one of the organization admins.

+# Pickle Chunked Reading Benchmark
+
+This benchmark measures the performance impact of the chunked reading optimization in GH PR #119204 for the pickle module.
+
+## What This Tests
+
+The PR adds chunked reading (1MB chunks) to prevent memory exhaustion when unpickling large objects:
+- **BINBYTES8** - Large bytes objects (protocol 4+)
+- **BINUNICODE8** - Large strings (protocol 4+)
+- **BYTEARRAY8** - Large bytearrays (protocol 5)
+- **FRAME** - Large frames
+- **LONG4** - Large integers
+- An antagonistic mode that tests using memory denial of service inducing malicious pickles.
+
+## Quick Start
+
+```bash
+# Run full benchmark suite (1MiB → 200MiB, takes several minutes)
+build/python Tools/picklebench/memory_dos_impact.py
+
+# Test just a few sizes (quick test: 1, 10, 50 MiB)
+build/python Tools/picklebench/memory_dos_impact.py --sizes 1 10 50
+
+# Test smaller range for faster results
+build/python Tools/picklebench/memory_dos_impact.py --sizes 1 5 10
+
+# Output as markdown for reports
+build/python Tools/picklebench/memory_dos_impact.py --format markdown > results.md
+
+# Test with protocol 4 instead of 5
+build/python Tools/picklebench/memory_dos_impact.py --protocol 4
+```
+
+**Note:** Sizes are specified in MiB. Use `--sizes 1 2 5` for 1MiB, 2MiB, 5MiB objects.
+
+## Antagonistic Mode (DoS Protection Test)
+
+The `--antagonistic` flag tests **malicious pickles** that demonstrate the memory DoS protection:
+
+```bash
+# Quick DoS protection test (claims 10, 50, 100 MB but provides 1KB)
+build/python Tools/picklebench/memory_dos_impact.py --antagonistic --sizes 10 50 100
+
+# Full DoS test (default: 10, 50, 100, 500, 1000, 5000 MB claimed)
+build/python Tools/picklebench/memory_dos_impact.py --antagonistic
+```
+
+### What This Tests
+
+Unlike normal benchmarks that test **legitimate pickles**, antagonistic mode tests:
+- **Truncated BINBYTES8**: Claims 100MB but provides only 1KB (will fail to unpickle)
+- **Truncated BINUNICODE8**: Same for strings
+- **Truncated BYTEARRAY8**: Same for bytearrays
+- **Sparse memo attacks**: PUT at index 1 billion (would allocate huge array before PR)
+
+**Key difference:**
+- **Normal mode**: Tests real data, shows ~5% time overhead
+- **Antagonistic mode**: Tests malicious data, shows ~99% memory savings
+
+### Expected Results
+
+```
+100MB Claimed (actual: 1KB)
+  binbytes8_100MB_claim
+    Peak memory:     1.00 MB (claimed: 100 MB, saved: 99.00 MB, 99.0%)
+    Error: UnpicklingError  ← Expected!
+
+Summary:
+  Average claimed: 126.2 MB
+  Average peak:    0.54 MB
+  Average saved:   125.7 MB (99.6% reduction)
+Protection Status: ✓ Memory DoS attacks mitigated by chunked reading
+```
+
+**Before PR**: Would allocate full claimed size (100MB+), potentially crash
+**After PR**: Allocates 1MB chunks, fails fast with minimal memory
+
+This demonstrates the **security improvement** - protection against memory exhaustion attacks.
+
+## Before/After Comparison
+
+The benchmark includes an automatic comparison feature that runs the same tests on both a baseline and current Python build.
+
+### Option 1: Automatic Comparison (Recommended)
+
+Build both versions, then use `--baseline` to automatically compare:
+
+```bash
+# Build the baseline (main branch without PR)
+git checkout main
+mkdir -p build-main
+cd build-main && ../configure && make -j $(nproc) && cd ..
+
+# Build the current version (with PR)
+git checkout unpickle-overallocate
+mkdir -p build
+cd build && ../configure && make -j $(nproc) && cd ..
+
+# Run automatic comparison (quick test with a few sizes)
+build/python Tools/picklebench/memory_dos_impact.py \
+  --baseline build-main/python \
+  --sizes 1 10 50
+
+# Full comparison (all default sizes)
+build/python Tools/picklebench/memory_dos_impact.py \
+  --baseline build-main/python
+```
+
+The comparison output shows:
+- Side-by-side metrics (Current vs Baseline)
+- Percentage change for time and memory
+- Overall summary statistics
+
+### Interpreting Comparison Results
+
+- **Time change**: Small positive % is expected (chunking adds overhead, typically 5-10%)
+- **Memory change**: Negative % is good (chunking saves memory, especially for large objects)
+- **Trade-off**: Slightly slower but much safer against memory exhaustion attacks
+
+### Option 2: Manual Comparison
+
+Save results separately and compare manually:
+
+```bash
+# Baseline results
+build-main/python Tools/picklebench/memory_dos_impact.py --format json > baseline.json
+
+# Current results
+build/python Tools/picklebench/memory_dos_impact.py --format json > current.json
+
+# Manual comparison
+diff -y <(jq '.' baseline.json) <(jq '.' current.json)
+```
+
+## Understanding the Results
+
+### Critical Sizes
+
+The default test suite includes:
+- **< 1MiB (999,000 bytes)**: No chunking, allocates full size upfront
+- **= 1MiB (1,048,576 bytes)**: Threshold, chunking just starts
+- **> 1MiB (1,048,577 bytes)**: Chunked reading engaged
+- **1, 2, 5, 10MiB**: Show scaling behavior with chunking
+- **20, 50, 100, 200MiB**: Stress test large object handling
+
+**Note:** The full suite may require more than 16GiB of RAM.
+
+### Key Metrics
+
+- **Time (mean)**: Average unpickling time - should be similar before/after
+- **Time (stdev)**: Consistency - lower is better
+- **Peak Memory**: Maximum memory during unpickling - **expected to be LOWER after PR**
+- **Pickle Size**: Size of the serialized data on disk
+
+### Test Types
+
+| Test | What It Stresses |
+|------|------------------|
+| `bytes_*` | BINBYTES8 opcode, raw binary data |
+| `string_ascii_*` | BINUNICODE8 with simple ASCII |
+| `string_utf8_*` | BINUNICODE8 with multibyte UTF-8 (€ chars) |
+| `bytearray_*` | BYTEARRAY8 opcode (protocol 5) |
+| `list_large_items_*` | Multiple chunked reads in sequence |
+| `dict_large_values_*` | Chunking in dict deserialization |
+| `nested_*` | Realistic mixed data structures |
+| `tuple_*` | Immutable structures |
+
+## Expected Results
+
+### Before PR (main branch)
+- Single large allocation per object
+- Risk of memory exhaustion with malicious pickles
+
+### After PR (unpickle-overallocate branch)
+- Chunked allocation (1MB at a time)
+- **Slightly higher CPU time** (multiple allocations + resizing)
+- **Significantly lower peak memory** (no large pre-allocation)
+- Protection against DoS via memory exhaustion
+
+## Advanced Usage
+
+### Test Specific Sizes
+
+```bash
+# Test only 5MiB and 10MiB objects
+build/python Tools/picklebench/memory_dos_impact.py --sizes 5 10
+
+# Test large objects: 50, 100, 200 MiB
+build/python Tools/picklebench/memory_dos_impact.py --sizes 50 100 200
+```
+
+### More Iterations for Stable Timing
+
+```bash
+# Run 10 iterations per test for better statistics
+build/python Tools/picklebench/memory_dos_impact.py --iterations 10 --sizes 1 10
+```
+
+### JSON Output for Analysis
+
+```bash
+# Generate JSON for programmatic analysis
+build/python Tools/picklebench/memory_dos_impact.py --format json | python -m json.tool
+```
+
+## Interpreting Memory Results
+
+The **peak memory** metric shows the maximum memory allocated during unpickling:
+
+- **Without chunking**: Allocates full size immediately
+  - 10MB object → 10MB allocation upfront
+
+- **With chunking**: Allocates in 1MB chunks, grows geometrically
+  - 10MB object → starts with 1MB, grows: 2MB, 4MB, 8MB (final: ~10MB total)
+  - Peak is lower because allocation is incremental
+
+## Typical Results
+
+On a system with the PR applied, you should see:
+
+```
+1.00MiB Test Results
+  bytes_1.00MiB:     ~0.3ms, 1.00MiB peak  (just at threshold)
+
+2.00MiB Test Results
+  bytes_2.00MiB:     ~0.8ms, 2.00MiB peak  (chunked: 1MiB → 2MiB)
+
+10.00MiB Test Results
+  bytes_10.00MiB:    ~3-5ms, 10.00MiB peak (chunked: 1→2→4→8→10 MiB)
+```
+
+Time overhead is minimal (~10-20% for very large objects), but memory safety is significantly improved.

+# CPython Pixi packages
+
+This directory contains definitions for [Pixi
+packages](https://pixi.sh/latest/reference/pixi_manifest/#the-package-section) which can
+be built from the CPython source code.
+
+Downstream developers can make use of these packages by adding them as Git dependencies
+in a [Pixi workspace](https://pixi.sh/latest/first_workspace/), like:
+
+```toml
+[dependencies]
+python.git = "https://github.com/python/cpython"
+python.subdirectory = "Tools/pixi-packages/asan"
+```
+
+This is particularly useful when developers need to build CPython from source
+(for example, for an ASan or TSan-instrumented build), as it does not require any manual
+clone or build steps. Instead, Pixi will automatically handle both the build
+and installation of the package.
+
+Each package definition is contained in a subdirectory, but they share the build script
+`build.sh` in this directory. Currently defined package variants:
+
+- `default`
+- `freethreading`
+- `asan`: ASan-instrumented build
+- `tsan-freethreading`: TSan-instrumented free-threading build
+
+## Maintenance
+
+- Keep the `abi_tag` and `version` fields in each `variants.yaml` up to date with the
+  Python version
+- Update `build.sh` for any breaking changes in the `configure` and `make` workflow
+
+## Opportunities for future improvement
+
+- More package variants (such as UBSan)
+- Support for Windows
+- Using a single `pixi.toml` for all package variants is blocked on
+  [pixi#5248](https://github.com/prefix-dev/pixi/issues/5248)
+
+## Troubleshooting
+
+TSan builds may crash on Linux with
+```
+FATAL: ThreadSanitizer: unexpected memory mapping 0x7977bd072000-0x7977bd500000
+```
+To fix it, try reducing `mmap_rnd_bits`:
+
+```console
+$ sudo sysctl vm.mmap_rnd_bits
+vm.mmap_rnd_bits = 32  # too high for TSan
+$ sudo sysctl vm.mmap_rnd_bits=28  # reduce it
+vm.mmap_rnd_bits = 28
+```

-# Python WebAssembly (WASM) build
-
-**WASI support is [tier 2](https://peps.python.org/pep-0011/#tier-2).**
-**Emscripten support is [tier 3](https://peps.python.org/pep-0011/#tier-3).**
-
-This directory contains configuration and helpers to facilitate cross
-compilation of CPython to WebAssembly (WASM). Python supports Emscripten
-(*wasm32-emscripten*) and WASI (*wasm32-wasi*) targets. Emscripten builds
-run in modern browsers and JavaScript runtimes like *Node.js*. WASI builds
-use WASM runtimes such as *wasmtime*.
-
-**NOTE**: If you are looking for general information about WebAssembly that is
-not directly related to CPython, please see https://github.com/psf/webassembly.
-
-## Emscripten (wasm32-emscripten)
-
-### Build
-
-See [the devguide instructions for building for Emscripten](https://devguide.python.org/getting-started/setup-building/#emscripten).
-
-### Running from node
-
-If you want to run the normal Python CLI, you can use `python.sh`. It takes the
-same options as the normal Python CLI entrypoint, though the REPL does not
-function and will crash.
-
-`python.sh` invokes `node_entry.mjs` which imports the Emscripten module for the
-Python process and starts it up with the appropriate settings. If you wish to
-make a node application that "embeds" the interpreter instead of acting like the
-CLI you will need to write your own alternative to `node_entry.mjs`.
-
-
-### Running tests
-
-After building, you can run the full test suite with:
-```shell
-./cross-build/wasm32-emscripten/build/python/python.sh -m test -uall
-```
-You can run the browser smoke test with:
-```shell
-./Tools/wasm/emscripten/browser_test/run_test.sh
-```
-
-### The Web Example
-
-When building for Emscripten, a small web example will be built automatically
-in the ``web_example`` directory. To run the web example, ``cd`` into the
-``web_example`` directory, then run ``python server.py``. This will start a web
-server; you can then visit ``http://localhost:8000/`` in a browser to see a
-simple REPL example.
-
-The web example relies on a bug fix in Emscripten version 3.1.73 so if you build
-with earlier versions of Emscripten it may not work. The web example uses
-``SharedArrayBuffer``. For security reasons browsers only provide
-``SharedArrayBuffer`` in secure environments with cross-origin isolation. The
-webserver must send cross-origin headers and correct MIME types for the
-JavaScript and WebAssembly files. Otherwise the terminal will fail to load with
-an error message like ``ReferenceError: SharedArrayBuffer is not defined``. See
-more information here:
-https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer#security_requirements
-
-Note that ``SharedArrayBuffer`` is _not required_ to use Python itself, only the
-web example. If cross-origin isolation is not appropriate for your use case you
-may make your own application embedding `python.mjs` which does not use
-``SharedArrayBuffer`` and serve it without the cross-origin isolation headers.
-
-### Embedding Python in a custom JavaScript application
-
-You can look at `python.worker.mjs` and `node_entry.mjs` for inspiration. At a
-minimum you must import ``createEmscriptenModule`` and you need to call
-``createEmscriptenModule`` with an appropriate settings object. This settings
-object will need a prerun hook that installs the Python standard library into
-the Emscripten file system.
-
-#### NodeJs
-
-In Node, you can use the NodeFS to mount the standard library in your native
-file system into the Emscripten file system:
-```js
-import createEmscriptenModule from "./python.mjs";
-
-await createEmscriptenModule({
-    preRun(Module) {
-        Module.FS.mount(
-            Module.FS.filesystems.NODEFS,
-            { root: "/path/to/python/stdlib" },
-            "/lib/",
-        );
-    },
-});
-```
-
-#### Browser
-
-In the browser, the simplest approach is to put the standard library in a zip
-file it and install it. With Python 3.14 this could look like:
-```js
-import createEmscriptenModule from "./python.mjs";
-
-await createEmscriptenModule({
-  async preRun(Module) {
-    Module.FS.mkdirTree("/lib/python3.14/lib-dynload/");
-    Module.addRunDependency("install-stdlib");
-    const resp = await fetch("python3.14.zip");
-    const stdlibBuffer = await resp.arrayBuffer();
-    Module.FS.writeFile(`/lib/python314.zip`, new Uint8Array(stdlibBuffer), {
-      canOwn: true,
-    });
-    Module.removeRunDependency("install-stdlib");
-  },
-});
-```
-
-### Limitations and issues
-
-#### Network stack
-
-- Python's socket module does not work with Emscripten's emulated POSIX
-  sockets yet. Network modules like ``asyncio``, ``urllib``, ``selectors``,
-  etc. are not available.
-- Only ``AF_INET`` and ``AF_INET6`` with ``SOCK_STREAM`` (TCP) or
-  ``SOCK_DGRAM`` (UDP) are available. ``AF_UNIX`` is not supported.
-- ``socketpair`` does not work.
-- Blocking sockets are not available and non-blocking sockets don't work
-  correctly, e.g. ``socket.accept`` crashes the runtime. ``gethostbyname``
-  does not resolve to a real IP address. IPv6 is not available.
-- The ``select`` module is limited. ``select.select()`` crashes the runtime
-  due to lack of exectfd support.
-
-#### processes, signals
-
-- Processes are not supported. System calls like fork, popen, and subprocess
-  fail with ``ENOSYS`` or ``ENOSUP``.
-- Signal support is limited. ``signal.alarm``, ``itimer``, ``sigaction``
-  are not available or do not work correctly. ``SIGTERM`` exits the runtime.
-- Keyboard interrupt (CTRL+C) handling is not implemented yet.
-- Resource-related functions like ``os.nice`` and most functions of the
-  ``resource`` module are not available.
-
-#### threading
-
-- Threading is disabled by default. The ``configure`` option
-  ``--enable-wasm-pthreads`` adds compiler flag ``-pthread`` and
-  linker flags ``-sUSE_PTHREADS -sPROXY_TO_PTHREAD``.
-- pthread support requires WASM threads and SharedArrayBuffer (bulk memory).
-  The Node.JS runtime keeps a pool of web workers around. Each web worker
-  uses several file descriptors (eventfd, epoll, pipe).
-- It's not advised to enable threading when building for browsers or with
-  dynamic linking support; there are performance and stability issues.
-
-#### file system
-
-- Most user, group, and permission related function and modules are not
-  supported or don't work as expected, e.g.``pwd`` module, ``grp`` module,
-  ``os.setgroups``, ``os.chown``, and so on. ``lchown`` and ``lchmod`` are
-  not available.
-- ``umask`` is a no-op.
-- hard links (``os.link``) are not supported.
-- Offset and iovec I/O functions (e.g. ``os.pread``, ``os.preadv``) are not
-  available.
-- ``os.mknod`` and ``os.mkfifo``
-  [don't work](https://github.com/emscripten-core/emscripten/issues/16158)
-  and are disabled.
-- Large file support crashes the runtime and is disabled.
-- ``mmap`` module is unstable. flush (``msync``) can crash the runtime.
-
-#### Misc
-
-- Heap memory and stack size are limited. Recursion or extensive memory
-  consumption can crash Python.
-- Most stdlib modules with a dependency on external libraries are missing,
-  e.g. ``ctypes``, ``readline``, ``ssl``, and more.
-- Shared extension modules are not implemented yet. All extension modules
-  are statically linked into the main binary. The experimental configure
-  option ``--enable-wasm-dynamic-linking`` enables dynamic extensions
-  supports. It's currently known to crash in combination with threading.
-- glibc extensions for date and time formatting are not available.
-- ``locales`` module is affected by musl libc issues,
-  [gh-90548](https://github.com/python/cpython/issues/90548).
-- Python's object allocator ``obmalloc`` is disabled by default.
-- ``ensurepip`` is not available.
-
-#### In the browser
-
-- The interactive shell does not handle copy 'n paste and unicode support
-  well.
-- The bundled stdlib is limited. Network-related modules,
-  multiprocessing, dbm, tests and similar modules
-  are not shipped. All other modules are bundled as pre-compiled
-  ``pyc`` files.
-- In-memory file system (MEMFS) is not persistent and limited.
-- Test modules are disabled by default. Use ``--enable-test-modules`` build
-  test modules like ``_testcapi``.
