| | | | | | | during deprecation period (GH-117354) (cherry picked from commit 985917dc8d34e2d2f717f7a981580a8dcf18d53a) Co-authored-by: Steve Dower <steve.dower@python.org>
* [3.12] gh-113964: Don't prevent new threads until all non-daemon threads ↵Sam Gross2024-03-191-3/+3
| | | | | | | | | | | | | | 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 Bachmann2023-03-091-18/+40
| | | | | 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-100227: Isolate the Import State to Each Interpreter (gh-101941)Eric Snow2023-03-091-5/+8
| | | | | | | | | | | | Specific changes: * move the import lock to PyInterpreterState * move the "find_and_load" diagnostic state to PyInterpreterState Note that the import lock exists to keep multiple imports of the same module in the same interpreter (but in different threads) from stomping on each other. Independently, we use a distinct global lock to protect globally shared import state, especially related to loaded extension modules. For now we can rely on the GIL as that lock but with a per-interpreter GIL we'll need a new global lock. The remaining state in _PyRuntimeState.imports will (probably) continue being global. https://github.com/python/cpython/issues/100227

| | | | | | | | | | The objective of this change is to help make the GILState-related code easier to understand. This mostly involves moving code around and some semantically equivalent refactors. However, there are a also a small number of slight changes in structure and behavior: * tstate_current is moved out of _PyRuntimeState.gilstate * autoTSSkey is moved out of _PyRuntimeState.gilstate * autoTSSkey is initialized earlier * autoTSSkey is re-initialized (after fork) earlier https://github.com/python/cpython/issues/59956

* gh-100228: Warn from os.fork() if other threads exist. (#100229)Gregory P. Smith2022-12-291-0/+103
| | | | | 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.
