New submission from Christian Heimes: I have seen complains from e.g. Tarek that os.urandom() fails under high load: https://twitter.com/tarek_ziade/status/362281268215418880
The problem is caused by file descriptor limits. os.urandom() opens /dev/urandom for every call. How about os.urandom() uses a persistent file descriptor? That should eliminate the error. It may alsos speed up os.urandom() because a persistent FD gets rid of open() and close() syscalls. * open /dev/urandom on first call of os.urandom() and store the fd in a static var * invalidate, close fd on read() -> EINVAL; open /dev/urandom again * close fd when interpreter shuts down ---------- components: Extension Modules messages: 195338 nosy: christian.heimes, haypo, hynek, tarek priority: normal severity: normal stage: needs patch status: open title: os.urandom() fails under high load type: behavior versions: Python 2.7, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18756> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
