[issue19334] test_asyncio hanging for 1 hour (non-AIX version)
STINNER Victor added the comment: I looked at last tests of FreeBSD 6.4 3.x between builds 4400 and 4432. The builds 4401, 4408, 4416 and 4421 hanged but because of check_interrupted_write_retry() of test_io, but none hanged because of test_asyncio. I also checked builds 3620..3643 of x86 RHEL 6 3.x: all succeeded. Same on x86 Ubuntu Shared 3.x: no hang between builds 9560 and 9568. So I consider this issue as fixed. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19334 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

For what it's worth, the incidence of this failure dropped sharply over the subsequent 24 hours after the initial report. Could the relaxation of the timers in 042deeeb703 have had an effect?

[issue19334] test_asyncio hanging for 1 hour (non-AIX version)
New submission from Guido van Rossum: There are still some problems with asyncio tests hanging on FreeBSD and possibly other platforms. While these were originally conflated with a hang on AIX, the root causes are different; just the symptoms are the same (the test hangs forever and after exactly one hour the test runner kills the process). I'm opening a new issue to discuss the issues on platforms other than AIX. -- messages: 200790 nosy: db3l, gvanrossum, haypo, larry, ncoghlan, neologix, pitrou, python-dev, sbt, skrah priority: normal severity: normal status: open title: test_asyncio hanging for 1 hour (non-AIX version) type: behavior versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19334 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
