Serhiy Storchaka	ad0a3f733b	gh-131927: Do not emit PEP 765 warnings in ast.parse() (GH-139642) ... ast.parse() no longer emits syntax warnings for return/break/continue in finally (see PEP-765) -- they are only emitted during compilation.	2025-10-30 13:00:42 +02:00
Victor Stinner	80f20f58b2	gh-125434: Fix non-ASCII thread names in faulthandler on Windows (#140700) ... Add _Py_DumpWideString() function to dump a wide string as ASCII. It supports surrogate pairs. Replace _Py_EncodeLocaleRaw() with _Py_DumpWideString() in write_thread_name().	2025-10-28 14:41:51 +01:00
Peter Bierma	2cefa70eb9	gh-140544: Always assume that thread locals are available (GH-140690) ... Python has required thread local support since 3.12 (see GH-103324). By assuming that thread locals are always supported, we can improve the performance of third-party extensions by allowing them to access the attached thread and interpreter states directly.	2025-10-28 09:07:19 -04:00
Ken Jin	a716091227	gh-140104: Set next_instr properly in the JIT during exceptions (GH-140233) ... Co-authored-by: devdanzin <74280297+devdanzin@users.noreply.github.com> Co-authored-by: Chris Eibl <138194463+chris-eibl@users.noreply.github.com>	2025-10-27 18:26:47 +00:00

Itamar Oren	e8b5cb8f33	gh-140641: Break out of inittab search on match (GH-140642)	2025-10-27 15:18:58 +02:00

Mark Shannon	0c01090ad9	GH-139951: Fix major GC performance regression (GH-140262) ... * Count number of actually tracked objects, instead of trackable objects. This ensures that untracking tuples has the desired effect of reducing GC overhead * Do not track most untrackable tuples during creation. This prevents large numbers of small tuples causing execessive GCs.	2025-10-21 15:22:15 +01:00
Pål Grønås Drange	b2f9fb9db2	gh-140358: Bring back elapsed time and unreachable count to gc debug output (#140359)	2025-10-21 00:54:44 +01:00

Kumar Aditya	58c44c2bf2	gh-140067: Fix memory leak in sub-interpreter creation (#140111) (#140261) ... Fix memory leak in sub-interpreter creation caused by overwriting of the previously used `_malloced` field. Now the pointer is stored in the first word of the memory block to avoid it being overwritten accidentally. Co-authored-by: Kumar Aditya <kumaraditya@python.org>	2025-10-18 16:36:58 +05:30

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
Peter Bierma	0bcb1c25f7	Revert "gh-140067: Fix memory leak in sub-interpreter creation (#140111)" (#140140) ... This reverts commit 59547a251f.	2025-10-15 07:16:43 +05:30

Serhiy Storchaka	279db6bede	gh-139640: Fix swallowing syntax warnings in different modules (GH-139755) ... Revert GH-131993. Fix swallowing some syntax warnings in different modules if they accidentally have the same message and are emitted from the same line.	2025-10-14 17:48:09 +03:00

Victor Stinner	3d3f126e86	gh-139353: Rename formatter_unicode.c to unicode_formatter.c (#139723) ... * Move Python/formatter_unicode.c to Objects/unicode_formatter.c. * Move Objects/stringlib/localeutil.h content into unicode_formatter.c. Remove localeutil.h. * Move _PyUnicode_InsertThousandsGrouping() to unicode_formatter.c and mark the function as static. * Rename unicode_fill() to _PyUnicode_Fill() and export it in pycore_unicodeobject.h. * Move MAX_UNICODE to pycore_unicodeobject.h as _Py_MAX_UNICODE.	2025-10-08 14:56:00 +02:00

Petr Viktorin	01157e0cdf	gh-139116: tracemalloc: Detach thread state when acquiring tables_lock (GH-139449) ... * gh-139116: tracemalloc: Detach thread state when acquiring tables_lock This prevents a deadlock when: - One thread is in `_PyTraceMalloc_Stop`, with `TABLES_LOCK` held, calling `PyRefTracer_SetTracer` which wants to stop the world - Another is thread in `PyTraceMalloc_Track`, just attached thread state, waiting for `TABLES_LOCK` Detaching the thread state while waiting for `TABLES_LOCK` allows `PyRefTracer_SetTracer` to stop the world.

Rok Mandeljc	7016044de9	gh-139231: Fix estimation of available stack size for recursion limit on macOS (GH-139232) ... Use `pthread_get_stackaddr_np()` and `pthread_get_stacksize_np()` to determine the stack address and size.	2025-09-24 11:57:00 +01:00
Donghee Na	c4f21d7c7c	gh-133171: Re-enable JUMP_BACKWARD to free-threading build (gh-137800)	2025-09-24 14:19:17 +09:00
Serhiy Storchaka	1a2e00c97a	gh-67795: Accept any real numbers as timestamp and timeout (GH-139224) ... Functions that take timestamp or timeout arguments now accept any real numbers (such as Decimal and Fraction), not only integers or floats, although this does not improve precision.	2025-09-23 21:31:42 +03:00
Victor Stinner	e8382e55c5	gh-74857, PEP 538: Coerce POSIX locale to UTF-8 based locale (#139238)	2025-09-23 19:20:59 +02:00

Peter Bierma	9243a4b933	gh-126016: Remove bad assertion in PyThreadState_Clear (GH-139158) ... In the _interpreters module, we use PyEval_EvalCode() to run Python code in another interpreter. However, when the process receives a KeyboardInterrupt, PyEval_EvalCode() will jump straight to finalization rather than returning. This prevents us from cleaning up and marking the thread as "not running main", which triggers an assertion in PyThreadState_Clear() on debug builds. Since everything else works as intended, remove that assertion.	2025-09-19 12:17:05 +00:00
Peter Bierma	3eec897752	gh-136003: Skip non-daemon threads when exceptions occur during finalization (GH-139129) ... During finalization, we need to mark all non-daemon threads as daemon to quickly shut down threads when sending CTRL^C to the process. This was a minor regression from GH-136004.	2025-09-18 16:04:01 -04:00
