New submission from Alexey Poryadin: When is called `select`, but registered no one `fileobject` rise exception: ... polled = self._selector.select(timeout) File "/usr/lib/python3.4/selectors.py", line 424, in select fd_event_list = self._epoll.poll(timeout, max_ev) ValueError: maxevents must be greater than 0, got 0
Of course, it makes no sense to call `select` if there is nothing to watch. But "select.epol.poll" is not raises exception in the same case if `max_ev`=-1. And this simplifies the application code and is useful if need just sleep for a timeout. So, I suggest a small fix: - fd_event_list = self._epoll.poll(timeout, max_ev) + fd_event_list = self._epoll.poll(timeout, max_ev or -1) ---------- messages: 232300 nosy: Alexey.Poryadin priority: normal severity: normal status: open title: selectors.EpollSelector.select raises exception when nothing to select. type: behavior versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23009> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
