STINNER Victor <vstin...@python.org> added the comment:
The script fails with "ChildProcessError: [Errno 10] No child processes" on line: > os.waitpid(child.pid, 0) The line before, you call child.kill() which sends SIGKILL signal to the process. So it's likely that the process will complete (killed by SIGKILL) soon. I don't think that it's a good idea to attempt reading the process status directly (by calling os.waitpid), since subprocess already tracks the process status. There is the public child.poll() API which calls os.waitpid(child.pid, 0) in a safe way for you. Why not using this API? IMO this issue is not a bug. Note: Python 3.8 behaves differently, but it doesn't mean that calling directly os.waitpid() was a good idea in Python 3.8 and older ;-) ---------- nosy: +gregory.p.smith, vstinner _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42558> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
