@hroncok see comment msg339370 Vanilla 3.7.0 (re-confirmed) didn't contain the change, nor did 3.6.8 (ok, that isn't vanilla) but both can hang using the test. It can take a while and, subjectively, it seems to depend on machine load. I've even struggled to get 3.7.3 to fail without load. Presumably there's a race and grinding the test machine into the ground increases the odds of it happening. The patch for bpo-6721 could be causing many things, but two to mind: - turning this bug into bpo-36533 (aka bpo-6721 caused a regression) - slowed down the fork (sending time acquiring locks) which increased the odds of this hang My hunch is the latter as the stack dumps look nothing like those I analyzed for bpo-36533 (see messages msg339454 and msg339458). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35866> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
