STINNER Victor added the comment: I commited asyncio_read_from_self.patch into Tulip, Python 3.4 and 3.5. If someone is interested to work on more advanced enhancement, please open a new issue.
Oh by, a workaround is to limit the number of concurrent processes. Without the patch, "./python test_subprocess_error.py 5 1000" (max: 5 concurrenet processes) emits a lot of "BlockingIOError: [Errno 11] Resource temporarily unavailable" message. With the patch, I start getting messages with 140 concurrent processes, which is much better :-) IMO more than 100 concurrent processes is crazy, don't do that at home :-) I mean processes with a very short lifetime. The limit is the number of SIGCHLD per second, so the number of processes which end at the same second. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21595> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
