Serhiy Storchaka	20d5494c88	Revert "gh-66234: Add flag to disable the use of mmap in dbm.gnu (GH-135005)" (GH-136989) ... This reverts commit 0cec424af5.	2025-09-20 11:01:44 +03:00
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
Pablo Galindo Salgado	67636f72d2	gh-138709: Implement CPU time profiling in profiling.sample (#138710)	2025-09-19 19:17:28 +01:00

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

Adam Turner	1ebd726c9b	gh-64490: Argument Clinic: Add support for `**kwds` (#138344) ... This adds a scaffold of support, initially only working with strictly positional-only arguments. The FASTCALL calling convention is not yet supported.	2025-09-18 13:31:42 +00:00

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
Benjamin Johnson	ab6893ab5c	gh-138514: getpass: restrict echo_char to a single ASCII character (#138591) ... This amends commit bf8bbe9a81 by restricting `echo_char` in `getpass.getpass` to single printable ASCII characters as it would be uncommon to use long strings or multi-byte characters for keyboard feedback. --------- Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com> Co-authored-by: Brian Schubert <brianm.schubert@gmail.com>	2025-09-16 16:21:55 +02:00

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
