Pablo Galindo Salgado	9df477c0ce	gh-138709: Fix race condition in test_external_inspection (#139209) ... Fix race condition in test_external_inspection thread status tests The tests test_thread_status_detection and test_thread_status_gil_detection had a race condition where the test could sample thread status between when the sleeper thread sends its "ready" message and when it actually calls time.sleep(). This caused intermittent test failures where the sleeper thread would show as running (status=0) instead of idle (status=1 or 2). The fix moves the thread status collection inside the retry loop and specifically waits for the expected thread states before proceeding with assertions. The retry loop now continues until: - The sleeper thread shows as idle (status=1 for CPU mode, status=2 for GIL mode) - The busy thread shows as running (status=0) - Both thread IDs are found in the status collection This ensures the test waits for threads to settle into their expected states before making assertions, eliminating the race condition.	2025-09-21 18:32:03 +01:00

Cody Maloney	69c6b438e8	gh-138013: Split SignalsTest from test_io.test_general (#139079) ... Increase parallelism by splitting out `SignalsTest` from test_general. `SignalsTest` takes 24.2 seconds on my dev machine when fully enabled making it the largest part of `test_io`. Code move done via copy/paste then tweak imports. After splitting `test_io.test_general` is down to 10.1 seconds on my dev box with all parts enabled.	2025-09-19 18:21:50 +00:00

Serhiy Storchaka	7257b24140	gh-139076: Fix regression in pydoc not showing extension functions (GH-139077) ... Fix a bug in the pydoc module that was hiding functions in a Python module if they were implemented in an extension module and the module did not have __all__.	2025-09-19 15:54:06 +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

Malcolm Smith	0ac377ff23	Make Android streams respect the unbuffered (-u) option (#138806) ... Android pipes stdout/stderr to the log, which means every write to the log becomes a separate log line. As a result, most practical uses of stdout/stderr should be buffered; but it doesn't hurt to preserve unbuffered handling in case it's useful.	2025-09-18 11:41:21 +01:00
Cody Maloney	db68bfc771	gh-138720: Make Buffered closed check match flush (GH-138724) ... In `_io__Buffered_flush_impl` the macro `CHECK_CLOSED` is used to check the `buffered*` is in a good state to be flushed. That differs slightly from `buffered_closed`. In some cases, that difference would result in `close()` thinking the file needed to be flushed and closed while `flush()` thought the file was already closed. This could happen during GC and would result in an unraisable exception.	2025-09-18 12:02:29 +02:00

Jelle Zijlstra	6d6aba2523	gh-137226: Fix get_type_hints() on generic TypedDict with stringified annotations (#138953) ... This issue appears specifically for TypedDicts because the TypedDict constructor code converts string annotations to ForwardRef objects, and those are not evaluated properly by the get_type_hints() stack because of other shenanigans with type parameters. This issue does not affect normal generic classes because their annotations are not pre-converted to ForwardRefs. The fix attempts to restore the pre- #137227 behavior in the narrow scenario where the issue manifests. It mostly makes changes only in the paths accessible from get_type_hints(), ensuring that newer APIs (such as evaluate_forward_ref() and annotationlib) are not affected by get_type_hints()'s past odd choices. This PR does not fix issue #138949, an older issue I discovered while playing around with this one; we'll need a separate and perhaps more invasive fix for that, but it should wait until after 3.14.0.	2025-09-16 07:28:39 -07:00

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
