Alexey Izbyshev <izbys...@ispras.ru> added the comment: Regarding fixing (1), I'm worrying about backward compatibility a bit. Some people who discovered that behavior might rely on such "move" semantics and expect that the redirected descriptor is not leaked into the child. OTOH, since descriptors are non-inheritable by default since 3.4, it might be less of an issue now. What do you think?
Otherwise, yes, I'd like to fix this, but fixing is a bit trickier than it may seem because sometimes descriptors are duplicated in _posixsubprocess.c (in case of low fds), so we need to track the ownership properly. I've already performed some work and discovered another issue: in a corner case involving closed standard fds, pipes created by subprocess may leak into the child and/or an incorrect redirection may occur. Since I can't completely fix this issue without affecting a discovered one, I think I'll do the opposite: file a new issue, fix it, and then go back to this one. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32270> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
