* bpo-36402: Fix threading._shutdown() race condition (GH-13948) (GH-14050) ↵Miss Islington (bot)2019-06-131-3/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | (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. (cherry picked from commit 6f75c873752a16a7ad8f35855b1e29f59d048e84) (cherry picked from commit e40a97a721d46307dfdc2b0322028ccded6eb571) Co-authored-by: Victor Stinner <vstinner@redhat.com>

* bpo-32593: Drop FreeBSD 9 and older support (#5232)Victor Stinner2018-01-221-2/+1
| | | Drop support of FreeBSD 9 and older.
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-4/+4
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.

* bpo-31234: test_threading: fix ref cycle (#3150)Victor Stinner2017-08-181-0/+2
| | | | test_bare_raise_in_brand_new_thread() now explicitly breaks a reference cycle to not leak a dangling thread.
* bpo-30387: Fix warning in test_threading (#1634)Victor Stinner2017-05-171-3/+5
| | | | | | | | | test_is_alive_after_fork() now joins directly the thread to avoid the following warning added by bpo-30357: Warning -- threading_cleanup() failed to cleanup 0 threads after 2 sec (count: 0, dangling: 21) Use also a different exit code to catch generic exit code 1.
* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-3/+6
| | | | | | | | | | | * bpo-6532: Make the thread id an unsigned integer. From C API side the type of results of PyThread_start_new_thread() and PyThread_get_thread_ident(), the id parameter of PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState changed from "long" to "unsigned long". * Restore a check in thread_get_ident().

* | Get "stopped" back into repr(Thread) when appropriate.Tim Peters2013-09-091-0/+25
| | | | | | | | | | | | | | | | | | | | 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.
* | Issue 18984: Remove ._stopped Event from Thread internals.Tim Peters2013-09-081-137/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Thread.join() now waits for the underlying thread state to be ↵Antoine Pitrou2013-09-071-2/+68
