New submission from STINNER Victor <vstin...@python.org>:
test_threading.ThreadJoinOnShutdown.test_reinit_tls_after_fork() does crash randomly on AIX in logging._after_at_fork_child_reinit_locks(): https://bugs.python.org/issue40068#msg365028 This function ends by releasing a lock: _releaseLock() # Acquired by os.register_at_fork(before=. But it is not safe to use a lock after fork (see bpo-6721 and bpo-40089). The purpose of _after_at_fork_child_reinit_locks() is already to fix locks used by logging handles: see bpo-36533 and commit 64aa6d2000665efb1a2eccae176df9520bf5f5e6. But the global logging._lock is not reset after fork. Attached PR fix the issue. ---------- components: Library (Lib) messages: 365170 nosy: vstinner priority: normal severity: normal status: open title: Crash in logging._after_at_fork_child_reinit_locks() versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40091> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
