STINNER Victor <victor.stin...@haypocalc.com> added the comment: The problem is that faulthandler's thread (faulthandler_thread) receives the SIGALRM signal: the signal interrupts sem_timedwait() which returns EINTR. PyThread_acquire_lock_timed() retries sem_timedwait() and so the other thread executing sendall() is not interrupted.
The solution is to configure which signals are handled by faulthandler_thread() using pthread_sigmask(): http://hg.python.org/sandbox/haypo/rev/4257fdfa5661 I forced a build on x86 FreeBSD (custom) buildbot: http://www.python.org/dev/buildbot/all/builders/x86%20FreeBSD%20custom I already tested sigprocmask() on FreeBSD (in my VM) and it works as expected: test_socket doesn't block anymore. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11753> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
