As a side note, in the general case, there's more than a performance optimization: the problem with unregister() + register() vs a real modify (e.g. EPOLL_CTL_MOD) is that it's subject to a race condition, if an event fires during the short window where the FD isn't registered anymore. But since selectors use level-triggered notification, that's not an issue: I'll probably add a comment in the code explaining why it's safe, though. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16853> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
