This is still the case on windows as the pipes created to talk to the process might be inherited by two or more simultaneous CreateProcess calls. I've found a suggested solution to this: https://devblogs.microsoft.com/oldnewthing/20111216-00/?p=8873 By only inheriting the stdout/err/in handles and them supporting close_fds for windows. Would more users be interested in a proper patch for this? For us now we have a lock around Popen.__init__ but that obviously doesn't suport subinterpreters and other calls to CreateProcess that might happen. ---------- nosy: +santagada versions: +Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue19809> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
