David Bolen added the comment: In running the test under a local build, the issue is very repeatable, but I believe it's actually due to slow process startup rather than a quick exit.
That is, adding a brief sleep after process creation and just before the Request() call seems to fix the problem. I'm guessing the buildbot is sluggish enough that it just takes a bit longer for the process to start and be ready to be used. Whether or not that's purely a machine or test problem, or whether it means that perhaps subprocess.Popen() is returning sooner than it should with a process that isn't ready yet is unclear. (Or even if subprocess can tell) With the machine fairly idle, it looks like the minimum workable delay is about 200ms - probably something a bit longer would be safer under load, if looking for a quick workaround. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30225> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
