* bpo-36402: Fix threading._shutdown() race condition (GH-13948) (GH-14050) ↵Miss Islington (bot)2019-06-131-9/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-14054) * bpo-36402: Fix threading._shutdown() race condition (GH-13948) Fix a race condition at Python shutdown when waiting for threads. 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. (cherry picked from commit 468e5fec8a2f534f1685d59da3ca4fad425c38dd) * bpo-36402: Fix threading.Thread._stop() (GH-14047) Remove the _tstate_lock from _shutdown_locks, don't remove None.

* | Get "stopped" back into repr(Thread) when appropriate.Tim Peters2013-09-091-0/+1
| | | | | | | | | | | | | | | | | | | | Due to recent changes, a Thread doesn't know that it's over before someone calls .join() or .is_alive(). That meant repr(Thread) continued to include "started" (and not "stopped") before one of those methods was called, even if hours passed since the thread ended. Repaired that.
* | Another stab at the thread cleanup patch.Tim Peters2013-09-091-3/+26
| | | | | | | | | | | | | | | | | | | | Antoine Pitrou found a variation that worked for him on the thread+fork tests, and added an important self._is_stopped = True to the after-fork code. I confess I don't know why things passed before. But then mixing fork with threads is insane ;-)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix for issue 18808 left us checking two things to be sure a Thread was done: an Event (._stopped) and a mutex (._tstate_lock). Clumsy & brittle. This patch removes the Event, leaving just a happy lock :-) The bulk of the patch removes two excruciating tests, which were verifying sanity of the internals of the ._stopped Event after a fork. Thanks to Antoine Pitrou for verifying that's the only real value these tests had. One consequence of moving from an Event to a mutex: waiters (threads calling Thread.join()) used to block each on their own unique mutex (internal to the ._stopped event), but now all contend on the same mutex (._tstate_lock). These approaches have different performance characteristics on different platforms. I don't think it matters in this context.
* | Issue #18808 again: fix the after-fork logic for not-yet-started or ↵Antoine Pitrou2013-09-081-9/+7
| | | | | | | | | | | | already-stopped threads. (AFAICT, in theory, we must reset all the locks, not just those in use)
* | Issue 18808: blind attempt to repair some buildbot failures.Tim Peters2013-09-081-1/+6
| | | | | | | | | | | | | | test_is_alive_after_fork is failing on some old Linux kernels, but passing on all newer ones. Since virtually anything can go wrong with locks when mixing threads with fork, replace the most likely cause with a redundant simple data member.
* | Issue #18808: Thread.join() now waits for the underlying thread state to be ↵Antoine Pitrou2013-09-071-32/+55
| | | | | | | | | | | | destroyed before returning. This prevents unpredictable aborts in Py_EndInterpreter() when some non-daemon threads are still running.
