Gregory P. Smith added the comment: Here's a patch with a unittest that reproduces the problem with fixes to stop using any end_fds. The max fd is only ever used in the absolute fallback situation where no way to get a list of open fd's is available. In that case it is obtained from sysconf() at the time it is needed rather than module load time as sysconf() is async-signal-safe.
I'm not worried about calling close() an additional time on EINTR in the single threaded child process prior to exec(). The most that will happen is one extra call with a different error if the fd is in a bad state from the previous one. That is better than any chance of one being left open. ---------- stage: -> patch review type: security -> behavior Added file: http://bugs.python.org/file35425/issue21618-34-gps01.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21618> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
