Serhiy Storchaka	364ae607d8	gh-140634: Fix a reference counting bug in os.sched_param.__reduce__() (GH-140667)	2025-10-27 21:42:32 +02:00
Cody Maloney	0f0a362768	gh-140607: Validate returned byte count in RawIOBase.read (#140611) ... While `RawIOBase.readinto` should return a count of bytes between 0 and the length of the given buffer, it is not required to. Add validation inside RawIOBase.read() that the returned byte count is valid. Co-authored-by: Shamil <ashm.tech@proton.me> Co-authored-by: Victor Stinner <vstinner@python.org>	2025-10-27 18:06:46 +00:00
Alper	9479a62a51	gh-116738: Use PyMutex for bz2 module (gh-140555) ... The methods are already wrapped with a lock, which makes them thread-safe in free-threaded build. This replaces `PyThread_acquire_lock` with `PyMutex` and removes some macros and allocation handling code. Also add a test for free-threading to ensure we aren't getting data races and that the locking is working.	2025-10-27 09:52:30 -04:00
Petr Viktorin	18e4a89e42	gh-134160: Add more comments for the xxlimited module (GH-140214)	2025-10-27 11:39:42 +01:00

Kumar Aditya	95e5d59630	gh-140414: add fastpath for current running loop in asyncio.all_tasks (#140542) ... Optimize `asyncio.all_tasks()` for the common case where the event loop is running in the current thread by avoiding stop-the-world pauses and locking. This optimization is already present for `asyncio.current_task()` so we do the same for `asyncio.all_tasks()`.	2025-10-24 20:02:17 +05:30
Victor Stinner	5d2edf72d2	gh-83714: Set os.statx().stx_mode to None if missing from stx_mask (#140484) ... * Set stx_mode to None if STATX_TYPE|STATX_MODE is missing from stx_mask. * Enhance os.statx() tests. * statx_result structure: remove atime_sec, btime_sec, ctime_sec and mtime_sec members. Compute them on demand when stx_atime, stx_btime, stx_ctime and stx_mtime are read. * Doc: fix statx members sorting.	2025-10-23 22:35:17 +02:00
Abhishek Tiwari	f0291c3f2d	gh-140443: Use fma in loghelper to improve accuracy of log for very large integers (#140469) ... * gh-140443:use fma in loghelper to improve accuracy of log for very large integers Use fused multiply-add in log_helper() for huge ints. Saving a rounding here is remarkably effective. Across some millions of randomized test cases with ints up to a billion bits, on Windows and using log10, the ULP error distribution was dramatically flattened, and its range was nearly cut in half. In fact, the largest error Tim saw was under 0.6 ULP. --------- Co-authored-by: abhi210 <27881020+Abhi210@users.noreply.github.com> Co-authored-by: Stan Ulbrych <89152624+StanFromIreland@users.noreply.github.com>	2025-10-23 12:05:12 -05:00

Jeffrey Bosboom	60df1d7e0c	gh-83714: Check for struct statx members in configure (#140402) ... Some systems have the definitions of the mask bits without having the corresponding members in struct statx. Add configure checks for members added after Linux 4.11 (when statx itself was added).	2025-10-21 18:13:14 +02:00

Sam Gross	f11ec6e643	gh-140263: Fix data race in test_lock_two_threads (gh-140264) ... Clang-20 detects a data race between the unlock and the non-atomic read of the lock state. Use a relaxed load for the assertion to avoid the race.	2025-10-20 09:58:05 -04:00

Jeffrey Bosboom	5a31024da4	gh-83714: Check for struct statx.stx_atomic_write_unit_max_opt in configure (#140185) ... stx_atomic_write_unit_max_opt was added in Linux 6.16, but is controlled by the STATX_WRITE_ATOMIC mask bit added in Linux 6.11. That's safe at runtime because all kernels clear the reserved space in struct statx and zero is a valid value for stx_atomic_write_unit_max_opt, and it avoids allocating another mask bit, which are a limited resource. But it also means the kernel headers don't provide a way to check whether stx_atomic_write_unit_max_opt exists, so add a configure check.	2025-10-16 13:40:47 +02:00
Victor Stinner	4641925bf2	Set type names earlier in posixmodule.c (#140168)	2025-10-16 12:54:57 +02:00
Serhiy Storchaka	2a2bc82cef	gh-130567: Remove optimistic allocation in locale.strxfrm() (GH-137143) ... On modern systems, the result of wcsxfrm() is much larger the size of the input string (from 4+2*n on Windows to 4+5*n on Linux for simple ASCII strings), so optimistic allocation of the buffer of the same size never works. The exception is if the locale is "C" (or unset), but in that case the `wcsxfrm` call should be fast (and calling `locale.strxfrm()` doesn't make too much sense in the first place).	2025-10-16 09:54:41 +02:00
Jonathan Protzenko	3a81313019	gh-140120: Refresh HACL* to fix an hmac memory leak (GH-140188) ... This pulls an updated version of HACL* that fixes the memory leak reported in #140120, via an upstream fix.	2025-10-16 05:25:51 +00:00

yihong	a05aece543	gh-140080: Clear atexit callbacks when memory allocation fails during finalization (GH-140103) ... This fixes a regression introduced by GH-136004, in which finalization would hang while executing atexit handlers if the system was out of memory. --------- Signed-off-by: yihong0618 <zouzou0208@gmail.com> Co-authored-by: Peter Bierma <zintensitydev@gmail.com> Co-authored-by: Victor Stinner <vstinner@python.org>	2025-10-15 09:49:55 -04:00
Sergey Miryanov	32c264982e	gh-140061: Use _PyObject_IsUniquelyReferenced() to check if objects are uniquely referenced (gh-140062) ... The previous `Py_REFCNT(x) == 1` checks can have data races in the free threaded build. `_PyObject_IsUniquelyReferenced(x)` is a more conservative check that is safe in the free threaded build and is identical to `Py_REFCNT(x) == 1` in the default GIL-enabled build.	2025-10-15 09:48:21 -04:00

Emma Smith	f262297d52	gh-139877: Use PyBytesWriter in pycore_blocks_output_buffer.h (#139976) ... Previously, the _BlocksOutputBuffer code creates a list of bytes objects to handle the output data from compression libraries. This ends up being slow due to the output buffer code needing to copy each bytes element of the list into the final bytes object buffer at the end of compression. The new PyBytesWriter API introduced in PEP 782 is an ergonomic and fast method of writing data into a buffer that will later turn into a bytes object. Benchmarks show that using the PyBytesWriter API is 10-30% faster for decompression across a variety of settings. The performance gains are greatest when the decompressor is very performant, such as for Zstandard (and likely zlib-ng). Otherwise the decompressor can bottleneck decompression and the gains are more modest, but still sizable (e.g. 10% faster for zlib)!
