Wait until the Python thread state of all non-daemon threads get deleted (join all non-daemon threads), rather than just wait until Python threads complete. * Add threading._shutdown_locks: set of Thread._tstate_lock locks of non-daemon threads used by _shutdown() to wait until all Python thread states get deleted. See Thread._set_tstate_lock(). * Add also threading._shutdown_locks_lock to protect access to threading._shutdown_locks. * Add test_finalization_shutdown() test. ---------- components: Library (Lib) messages: 345476 nosy: vstinner priority: normal severity: normal status: open title: Memory leaks regression caused by: Fix threading._shutdown() race condition versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37265> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
