* [3.12] GH-89727: Fix FD leak on `os.fwalk()` generator finalization. ↵Miss Islington (bot)2024-05-301-0/+21
| | | | | | | | | | | (GH-119766) (#119768) GH-89727: Fix FD leak on `os.fwalk()` generator finalization. (GH-119766) Follow-up to 3c890b50. Ensure we `os.close()` open file descriptors when the `os.fwalk()` generator is finalized.

* [3.12] gh-113964: Don't prevent new threads until all non-daemon threads ↵Sam Gross2024-03-191-8/+9
| | | | | | | | | | | | | | exit (GH-116677) (#117029) Starting in Python 3.12, we prevented calling fork() and starting new threads during interpreter finalization (shutdown). This has led to a number of regressions and flaky tests. We should not prevent starting new threads (or `fork()`) until all non-daemon threads exit and finalization starts in earnest. This changes the checks to use `_PyInterpreterState_GetFinalizing(interp)`, which is set immediately before terminating non-daemon threads.

* gh-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-3/+5
| | | | | Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs). CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes. `MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.

* gh-100228: Warn from os.fork() if other threads exist. (#100229)Gregory P. Smith2022-12-291-0/+28
| | | | | Not comprehensive, best effort warning. There are cases when threads exist on some platforms that this code cannot detect. macOS when API permissions allow and Linux with a readable /proc procfs present are the currently supported cases where a warning should show up reliably. Starting with a DeprecationWarning for now, it is less disruptive than something like RuntimeWarning and most likely to only be seen in people's CI tests - a good place to start with this messaging.
