STINNER Victor added the comment: > It still seems to me that this is pretty atypical use of selectors
I already implemented something similar to subprocess.Popen.communicate() when I was working on old Python versions without the timeout parameter of communicate(). http://ufwi.org/projects/edw-svn/repository/revisions/master/entry/trunk/src/nucentral/nucentral/common/process.py#L222 IMO calling select with a few file descriptors (between 1 and 3) and destroying quickly the "selector" is no a rare use case. If I would port my code to selectors, I don't want to rewrite it to keep the selector alive longer, just because selectors force me to use the super-powerful fast epoll/kqueue selector. (To be honest, I will probably not notice any performance impact. But I like reducing the number of syscalls, not the opposite :-)) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19465> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
