Victor Stinner	bb7c54d5ba	[3.12] gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191) (#129217) (#129221) ... [3.13] gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191) (#129217) gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191) 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().

Victor Stinner	6df22cbf60	[3.12] gh-128679: Fix tracemalloc.stop() race conditions (#128897) (#129022) ... [3.13] gh-128679: Fix tracemalloc.stop() race conditions (#128897) tracemalloc_alloc(), tracemalloc_realloc(), PyTraceMalloc_Track(), PyTraceMalloc_Untrack() and _PyTraceMalloc_TraceRef() now check tracemalloc_config.tracing after calling TABLES_LOCK(). _PyTraceMalloc_Stop() now protects more code with TABLES_LOCK(), especially setting tracemalloc_config.tracing to 1. Add a test using PyTraceMalloc_Track() to test tracemalloc.stop() race condition. Call _PyTraceMalloc_Init() at Python startup. (cherry picked from commit 6b47499510)	2025-01-19 13:24:14 +00:00
Miss Islington (bot)	9e542f9a46	[3.12] gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391) (#121393) ... gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391) The tracemalloc_tracebacks hash table has traceback keys and NULL values, but its destructors do not reflect this -- key_destroy_func is NULL while value_destroy_func is raw_free. Swap these to free the traceback keys instead. (cherry picked from commit db39bc42f9) Co-authored-by: Josh Brobst <jbrobst@proton.me>	2024-07-05 06:59:06 +00:00
