04/05/2016, 3:06 PMAnd this shard keeps failing, but I have no idea why: https://travis-ci.org/pantsbuild/pants/jobs/120902256 - b

04/05/2016, 3:06 PMI don't see why it would fail on this change but not the original lock switchover - b
bored-art-40741
04/05/2016, 3:13 PMhmmmm but it seems like maybe it's happening on Jenkins too - b

04/05/2016, 5:14 PMTry clear the cache? - b
bored-art-40741
04/05/2016, 5:34 PMIt looks like this shard is failing for others as well: https://travis-ci.org/pantsbuild/pants/pull_requests - b
bored-art-40741
04/05/2016, 5:36 PMI'm going to clear the cache, yeah - b
bored-art-40741
04/05/2016, 5:37 PMIf I can figure out how? - b
bored-art-40741
04/05/2016, 5:38 PMI don't see it as an option under "more options" - b
bored-art-40741
04/05/2016, 5:38 PMAnd I can't find it anywhere else - b

04/05/2016, 5:39 PMThe fact that Jenkins also hung in the same way is very sketchy though - w

@witty-crayon-22786 do you think the engine would interact with the lock differently?tests/python/pants_test/engine/exp/test_engine.py - b
bored-art-40741
04/05/2016, 5:42 PMI think that's the same stall as here too http://jenkins.pantsbuild.org/job/pants_ci.unit_tests/SHARD=0/169/console - b
bored-art-40741
04/05/2016, 5:43 PMYeah just aborted that build and it flushed the line showing it was in test_engine.py - b
bored-art-40741
04/05/2016, 5:47 PMConsidering the multiprocessing going on in that test / the engine, I wonder if it's managing to deadlock itself by holding a file lock inappropriately - r

04/05/2016, 5:47 PMtheres a known deadlock w/ python 2.7.11 iirc, could it be that we’re getting a different python on the problem shards? - r

04/05/2016, 5:51 PMThis should be fixed - b
bored-art-40741
04/05/2016, 5:57 PMOr we should disable the test until it is - r
rough-minister-58256
04/05/2016, 6:06 PMdo we have any evidence that this is whats causing the current travis hangs? - b
bored-art-40741
04/05/2016, 6:07 PMThat's the test that's hanging, and it hangs on both travis and jenkins - b
bored-art-40741
04/05/2016, 6:07 PMIt doesn't hang for me locally - b
bored-art-40741
04/05/2016, 6:07 PM(And I upgraded to 2.11 to double check) - b

04/05/2016, 6:13 PM@bored-art-40741: are you on osx or linux? - b

witty-crayon-22786
04/05/2016, 6:14 PMi suspect it is 2.7.11 + linux, since John is on linux - r
rough-minister-58256
04/05/2016, 6:14 PMI seem to recall reproing the 2.7.11 hang on osx
