STINNER Victor added the comment: I can reproduce the issue using "python test.py|cat". The problem is that sys.stdout is buffered and the buffer is flushed twice: once in the parent, once in the child. Just call sys.stdout.flush() before os.fork() should fix your issue.
I don't think that Python should flush buffers of all streams before fork, so I propose to close this issue. Except if you see something interesting to add to Python documentation. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17230> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
