* [3.12] gh-104690 Disallow thread creation and fork at interpreter ↵Miss Islington (bot)2023-06-041-0/+16
| | | | | | | | | | | | | | | | | | | | | finalization (GH-104826) (#105277) gh-104690 Disallow thread creation and fork at interpreter finalization (GH-104826) Disallow thread creation and fork at interpreter finalization. in the following functions, check if interpreter is finalizing and raise `RuntimeError` with appropriate message: * `_thread.start_new_thread` and thus `threading` * `posix.fork` * `posix.fork1` * `posix.forkpty` * `_posixsubprocess.fork_exec` when a `preexec_fn=` is supplied. --------- (cherry picked from commit ce558e69d4087dd3653207de78345fbb8a2c7835) Co-authored-by: chgnrdv <52372310+chgnrdv@users.noreply.github.com> Co-authored-by: Gregory P.

* gh-99726: Improves correctness of stat results for Windows, and uses faster ↵Steve Dower2023-03-161-1/+11
| | | | | API when available (GH-102149) This deprecates `st_ctime` fields on Windows, with the intent to change them to contain the correct value in 3.14. For now, they should keep returning the creation time as they always have.

* gh-102519: Add os.listdrives, os.listvolumes and os.listmounts on Windows ↵Steve Dower2023-03-101-0/+43

* 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-101881: Support (non-)blocking read/write functions on Windows pipes ↵Rayyan Ansari2023-02-161-0/+1
| | | | | | | | | | | | (GH-101882) * fileutils: handle non-blocking pipe IO on Windows Handle erroring operations on non-blocking pipes by reading the _doserrno code. Limit writes on non-blocking pipes that are too large. * Support blocking functions on Windows Use the GetNamedPipeHandleState and SetNamedPipeHandleState Win32 API functions to add support for os.get_blocking and os.set_blocking.

* 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.
* gh-89727: Fix os.walk RecursionError on deep trees (#99803)Jon Burdo2022-12-191-0/+43
| | | | | Use a stack to implement os.walk iteratively instead of recursively to avoid hitting recursion limits on deeply nested trees.

* gh-98393: Update test_os for bytes-like types (#98487)Victor Stinner2022-11-021-34/+12
| | | Address Serhiy Storchaka's review.
* gh-98393: os module reject bytes-like, only accept bytes (#98394)Victor Stinner2022-10-181-20/+12
| | | | | The os module and the PyUnicode_FSDecoder() function no longer accept bytes-like paths, like bytearray and memoryview types: only the exact bytes type is accepted for bytes strings.
* gh-43414: os.get_terminal_size() now uses the actual file descriptor on ↵Raghunandan Bhat2022-07-281-0/+13
| | | | Windows instead of mapping to standard handles (#93203)

* gh-90473: Make chmod a dummy on WASI, skip chmod tests (GH-93534)Christian Heimes2022-06-061-2/+3
| | | WASI does not have the ``chmod(2)`` syscall yet.
* gh-90473: WASI requires proper open(2) flags (GH-93529)Christian Heimes2022-06-061-1/+2
|
* gh-90473: Skip and document more failing tests on WASI (GH-93436)Christian Heimes2022-06-021-1/+7
| | | | | | | - Mark more ``umask()`` cases - ``dup()`` is not supported - ``/dev/null`` is not available - document missing features - mark more modules as not available
* gh-90473: Misc test fixes for WASI (GH-93218)Christian Heimes2022-05-251-0/+2
| | | | | | | | * ``sys.executable`` is not set * WASI does not support subprocess * ``pwd`` module is not available * WASI checks ``open`` syscall flags more strict, needs r, w, rw flag. * ``umask`` is not available * ``/dev/null`` may not be accessible
* gh-90473: Decrease recursion limit and skip tests on WASI (GH-92803)Christian Heimes2022-05-191-2/+7

* bpo-40280: Skip more tests on Emscripten (GH-31947)Christian Heimes2022-03-171-1/+9
| | | | | | - lchmod, lchown are not fully implemented - skip umask tests - cannot fstat unlinked or renamed files yet - ignore musl libc issues that affect Emscripten
* bpo-40280: Skip more tests/features that don't apply to Emscripten (GH-31791)Christian Heimes2022-03-101-0/+3
| | | | | | | - fd inheritance can't be modified because Emscripten doesn't support subprocesses anyway. - setpriority always fails - geteuid no longer causes problems with latest emsdk - umask is a stub - geteuid / getuid always return 0, but process cannot chown to random uid.
* bpo-40280: Block more non-working syscalls in Emscripten (GH-31757)Christian Heimes2022-03-081-0/+1
| | | | | | | | | - getgroups always fails. - geteuid and getegid always return 0 (root), which confuse tarfile and tests. - hardlinks (link, linkat) always fails. - non-encodable file names are not supported by NODERAWFS layer. - mark more tests with dependency on subprocess and multiprocessing. Mocking does not work if the module fails to import.
* bpo-40280: Address more test failures on Emscripten (GH-31050)Christian Heimes2022-02-051-0/+4

* bpo-42540: reallocation of id_mutex should not force default allocator ↵Sam Gross2021-11-171-0/+16
| | | | | | | (GH-29564) Unlike the other locks reinitialized by _PyRuntimeState_ReInitThreads, the "interpreters.main->id_mutex" is not freed by _PyRuntimeState_Fini and should not force the default raw allocator.
