* gh-129201: Use prefetch in GC mark alive phase. (gh-129203)Neil Schemenauer2025-02-051-42/+430
| | | For the free-threaded version of the cyclic GC, restructure the "mark alive" phase to use software prefetch instructions. This gives a speedup in most cases when the number of objects is large enough. The prefetching is enabled conditionally based on the number of long-lived objects the GC finds.
* gh-129354: Use PyErr_FormatUnraisable() function (#129523)Victor Stinner2025-02-051-3/+7

* gh-126835: Move optimization of constant sequence creation from codegen to ↵Kirill Podoprigora2025-02-012-47/+71
| | | | | | | | | | | | | | | | | | | | | | CFG (#129426) Codegen phase has an optimization that transforms ``` LOAD_CONST x LOAD_CONST y LOAD_CONXT z BUILD_LIST/BUILD_SET (3) ``` -> ``` BUILD_LIST/BUILD_SET (0) LOAD_CONST (x, y, z) LIST_EXTEND/SET_UPDATE 1 ``` This optimization has now been moved to CFG phase to make #128802 work.

* gh-129236: Use `stackpointer` in free threaded GC (#129240)Sam Gross2025-01-291-28/+52
| | | | | | The stack pointers in interpreter frames are nearly always valid now, so use them when visiting each thread's frame. For now, don't collect objects with deferred references in the rare case that we see a frame with a NULL stack pointer.

* GH-128914: Remove all but one conditional stack effects (GH-129226)Mark Shannon2025-01-279-436/+229

* gh-129185: Simplify PyTraceMalloc_Track() (#129256)Victor Stinner2025-01-242-26/+3
| | | | | | | | | | Since tracemalloc uses PyMutex, it becomes safe to use TABLES_LOCK() even after _PyTraceMalloc_Fini(): remove the "pre-check" in PyTraceMalloc_Track() and PyTraceMalloc_Untrack(). PyTraceMalloc_Untrack() no longer needs to acquire the GIL. _PyTraceMalloc_Fini() can be called earlier during Python finalization.
* gh-129185: Use PyMutex in tracemalloc (#129246)Victor Stinner2025-01-241-14/+3

* gh-129173: Use `_PyUnicodeError_GetParams` in `PyCodec_IgnoreErrors` (#129174)Bénédikt Tran2025-01-241-19/+43
| | | | We also cleanup `PyCodec_StrictErrors` and the error message rendered when an object of incorrect type is passed to codec error handlers.
* gh-126004: Fix positions handling in `codecs.backslashreplace_errors` (#127676)Bénédikt Tran2025-01-231-65/+64
| | | | This fixes how `PyCodec_BackslashReplaceErrors` handles the `start` and `end` attributes of `UnicodeError` objects via the `_PyUnicodeError_GetParams` helper.
* gh-129185: Remove internal TRACE_RAW_MALLOC macro (#129218)Victor Stinner2025-01-231-45/+3
| | | Always build tracemalloc with PyMem_RawMalloc() hooks.
* gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191)Victor Stinner2025-01-232-3/+26
| | | | | | | | | Support calling PyTraceMalloc_Track() and PyTraceMalloc_Untrack() during late Python finalization. * Call _PyTraceMalloc_Fini() later in Python finalization. * Test also PyTraceMalloc_Untrack() without the GIL * PyTraceMalloc_Untrack() now gets the GIL. * Test also PyTraceMalloc_Untrack() in test_tracemalloc_track_race().
* gh-126004: Fix positions handling in `codecs.replace_errors` (#127674)Bénédikt Tran2025-01-231-24/+22
