Pav Status/Result hangs, Run_Complete into BUILD_CREATED #334

Open CalvinDSeamons opened 4 years ago

CalvinDSeamons commented 4 years ago

I ran into a very strange bug while testing snow today. This happened on the Yellow front end where there are approximately 11,000 more tests sitting in the working_dir than the Turquoise, just wanted to mention that as that seems to be the only notable difference.

After launching my tests I ran watch pav status. Upon the loading of the status table (which only took 3-5 seconds) a few license-tests had already completed with PASS and the rest where all SCHEDULED, everything seemed fine. 20ish minutes later after everything had finished my watch pav status which updates every 3 seconds showed everything as fine, PASS. I quit out (don't ask me why) and ran just pav status as to copy the contents out into the ticket. The command hanged, as did pav result or any permutation of pav log build/run $series/$id ect. I even logged into snow from a different terminal session, loaded pavilion/2.0 and could not access the test run. Upon using thecat command i received the following status file from one of the tests that I had observed passing:

The PASS is what I observed inside watch pav status. When I exited watch pav status the test status changed to BUILD_CREATED and was unreachable from pav status.

I thought I'd make a note of it as @kjeverson could also not access anything through pav status. I was able to fix this by using scancel -u $user; pav cancel --all; module unload and reran my test. To whomever wants to investigate this further s377 still hangs when called and can be poked at in the yellow.

Update: 0013259 appears to be the test that is hanging.

I found out that the hanging was caused by one of the test_run's configs keeping a lock file (there was a config.lockfile in it's directory.)

But other than that all of the test_run statuses still end up in the BUILD_CREATED state:

This was another test I thought I'd throw into the issue:
