It looks like the OS never sent an event for more.txt.

andrewkroh · 2018-08-23T19:21:16Z

Looks like this occurred again in

There have been spurious test failures in test_file_integrity.Test.test_recursive (elastic#7731). This makes sure all errors encountered in recursiveWatcher are caught and logged, and also adds a debug message when a new recursive watch is added.

Even before more.txt, it never finds subdir/other/. This has been happening a few times each of the last few months. It's always on Linux, and always test_recursive (and not test_non_recursive which is similar). It might be a problem in fsnotify - unfortunately, it does not have any debug output. It might also be something in recursiveWatcher before it's reported.

Maybe something related to the concurrent map access in #8009 in which case #8027 should help.

I opened #8087 to add error catching everywhere the event could have been held up before being reported. If this happens again, we should have more information either way - a new error message or we've excluded a possible cause and need to dive into fsnotify (I hope not, it does not look pretty).

cwurm · 2018-08-28T17:10:38Z

I've merged #8087. I suggest we keep this issue open for a month or so to see if it still happens.

There have been spurious test failures in test_file_integrity.Test.test_recursive (#7731). This makes sure all errors encountered in recursiveWatcher are caught and logged, and also adds a debug message when a new recursive watch is added.

Skipping this test as it was flaky several times. See elastic#7731 for report.

This exact test failure does not seem to be happening anymore. There were others in this test that were fixed since then. Closing for now.
