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

Shamil	59547a251f	gh-140067: Fix memory leak in sub-interpreter creation (#140111) ... Fix memory leak in sub-interpreter creation caused by overwriting of the previously used `_malloced` field.

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.

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

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

Hood Chatham	2629ee4eb0	gh-128627: Use __builtin_wasm_test_function_pointer_signature for Emscripten trampoline (#137470) ... With https://github.com/llvm/llvm-project/pull/150201 being merged, there is now a better way to generate the Emscripten trampoline, instead of including hand-generated binary WASM content. Requires Emscripten 4.0.12.	2025-09-17 15:33:55 +01:00
Sam Gross	90fe3250f8	gh-137433: Fix deadlock with stop-the-world and daemon threads (gh-137735) ... There was a deadlock originally seen by Memray when a daemon thread enabled or disabled profiling while the interpreter was shutting down. I think this could also happen with garbage collection, but I haven't seen that in practice. The daemon thread could be hung while trying acquire the global rwmutex that prevents overlapping global and per-interpreter stop-the-world events. Since it already held the main interpreter's stop-the-world lock, it also deadlocked the main thread, which is trying to perform interpreter finalization. Swap the order of lock acquisition to prevent this deadlock. Additionally, refactor `_PyParkingLot_Park` so that the global buckets hashtable is left in a clean state if the thread is hung in `PyEval_AcquireThread`.	2025-09-16 09:21:58 +01:00

Serhiy Storchaka	af58a6f883	gh-88886: Remove excessive encoding name normalization (GH-137167) ... The codecs lookup function now performs only minimal normalization of the encoding name before passing it to the search functions: all ASCII letters are converted to lower case, spaces are replaced with hyphens. Excessive normalization broke third-party codecs providers, like python-iconv. Revert "bpo-37751: Fix codecs.lookup() normalization (GH-15092)" This reverts commit 20f59fe1f7.	2025-09-09 21:07:21 +03:00
Petr Viktorin	a92aec101e	gh-133143: Use _Py_ID for the other literals in sys (GH-138698) ... Follow-up refactoring after GH-133143, where we use `_Py_ID` for "big" and "little" in `abi_info.byteorder`. This uses `_Py_ID` for `sys.byteorder`, but also `float_repr_style` and a module name.	2025-09-09 14:57:07 +02:00
