* bpo-30654: Do not reset SIGINT handler to SIG_DFL in finisignal (GH-7146) ↵Miss Islington (bot)2018-06-011-12/+2
| | | | | | | (GH-7307) (cherry picked from commit e905c84494526363086f66a979e317e155bf9536) Co-authored-by: pkerling <pkerling@casix.org>
* [3.6] bpo-33329: Fix multiprocessing regression on newer glibcs (GH-6575) ↵Antoine Pitrou2018-04-231-6/+8
| | | | | | | | | | (GH-6582) Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some reserved signal numbers between 1 and NSIG. The `range(1, NSIG)` idiom is commonly used to select all signals for blocking with `pthread_sigmask`. So we ignore the sigaddset() return value until we expose sigfillset() to provide a better idiom. (cherry picked from commit 25038ecfb665bef641abf8cb61afff7505b0e008)

* [3.6] bpo-30807: signal.setitimer() may disable the timer by mistake ↵Antoine Pitrou2017-06-301-0/+4

* bpo-30038: fix race condition in signal delivery + wakeup fd (#1082) (#2075)Victor Stinner2017-06-101-7/+26
| | | | | | | | | | | | | | | | | | | | Before, it was possible to get the following sequence of events (especially on Windows, where the C-level signal handler for SIGINT is run in a separate thread): - SIGINT arrives - trip_signal is called - trip_signal writes to the wakeup fd - the main thread wakes up from select()-or-equivalent - the main thread checks for pending signals, but doesn't see any - the main thread drains the wakeup fd - the main thread goes back to sleep - trip_signal sets is_tripped=1 and calls Py_AddPendingCall to notify the main thread the it should run the Python-level signal handler - the main thread doesn't notice because it's asleep This has been causing repeated failures in the Trio test suite: https://github.com/python-trio/trio/issues/119 (cherry picked from commit 4ae01496971624c75080431806ed1c08e00f22c7)
