STINNER Victor added the comment: asyncio_subprocess_watchdog.patch:
* add test_asyncio.watchdog.setup_watchdog(): use faulthandler.dump_traceback_later() to kill the process if it hangs more than 'timeout' seconds (do nothing if faulthandler is not present, eg. on other Python VMs than CPython) * add SubprocessTestsMixin.debug_info(): return returncode, stdout, stderr * use debug_info() on functions using subprocess may may hang The patch should give more information on the child process if it hangs. I didn't see the test_asyncio hang on "AMD64 Snow Leop 3.x" recently. The hang is probably random :-/ I chose a default timeout of 5 minutes, it should be enough for the short tests of test_asyncio. You may set the timeout to 15 minutes if a buildbot is too slow. Or set the timeout to 1 minute if you prefer to not hang a buildbot too long. I tested asyncio_subprocess_watchdog.patch manually with a shorter timeout and by adding time.sleep(60) in echo.py, echo2.py and echo3.py. ---------- keywords: +patch Added file: http://bugs.python.org/file32750/asyncio_subprocess_watchdog.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19652> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
