STINNER Victor <victor.stin...@haypocalc.com> added the comment: Extract of manpage signal(7):
"The following interfaces are never restarted after being interrupted by a signal handler, regardless of the use of SA_RESTART; they always fail with the error EINTR when interrupted by a signal handler: * ... * File descriptor multiplexing interfaces: epoll_wait(2), epoll_pwait(2), poll(2), ppoll(2), select(2), and pselect(2)." Consider siginterrupt(signal, False) as a "best-effort" trick... which doesn't work with select(). If you don't want select() to be interrupted by SIGINT, use: pthread_sigmask(SIG_BLOCK, [SIGINT]); select(...) pthread_sigmask(SIG_UNBLOCK, [SIGINT]) or pselect(...., [SIGINT]) pselect() is atomic, whereas pthread_sigmask+select is not. I added recently pthread_sigmask() to the signal module in Python 3.3. pselect() is not exposed in Python currently. We may add it if it's needed. -- If you really don't care of SIGINT, you can also ignore it completly using signal(SIGINT, SIG_IGN). ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12224> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
