> File descriptors 0, 1, 2 are special: stdin, stdout and stderr file > descriptors. You should use stdin, stdout, and stderr parameter of subprocess. I finally find why `fd 0` is inherited. The reason is that os.dup2() has a parameter "inheritable" which defaults to True. Not because it's special stdin. I still think this is a bug. If some one closes fd 0, then he reopens it. it will not be inherited. ---------- _______________________________________ Python tracker <[email protected]> <https://bugs.python.org/issue46454> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
