Comment 2

[Mark Banner (:standard8)]

Ahal, this seems worryingly close to our ESLint issue about not always reporting an issue when run in parallel - Treeherder had 8 runs and 2 failed.

However, I've also just noticed that editor/libeditor/tests/browserscope/lib/richtext2/ is in ThirdPartyPaths.txt so this failure shouldn't be happening at all...

Comment 3

[Andrew Halberstadt [:ahal]]

I seem to be able to reliably reproduce with:
./mach lint -l file-whitespace editor

This likely started happening as of bug 1608386. Though the issue is deeper than that. I think file-whitespace linter isn't handling the exclude paths that mozlint passes to it properly. Though, this raises a larger issue: it would be better if mozlint could handle the path filtering entirely rather than expecting the underlying implementations to get it right. I'll see what I can do. Might need to land a quick fix here and file a follow-up for fixing this more permanently.

As for why this is intermittent.. I am still baffled. I agree that it looks very similar to the eslint issue. Maybe it's related to using * for shell expansion in our tasks? I'll use the eslint bug (bug 1608535) to investigate that one.

Comment 4

[Andrew Halberstadt [:ahal]]

I've identified this as a bug in the collapse algorithm caused by the fact that richtext is a substring of richtext2 (both are listed in ThirdPartyPaths.txt).

Comment 5

[Andrew Halberstadt [:ahal]]

Attachment: Bug 1608783 - [mozlint] Fix bug in 'collapse' when two paths are a prefix of one another, r?Standard8

This was happening because we had two exclude paths that were run through the 'collapse' algorithm:
editor/libeditor/tests/browserscope/lib/richtext
editor/libeditor/tests/browserscope/lib/richtext2

The problem was that in order to determine the base directory, the algorithm called
'os.path.commonprefix'. This function just returns the common string prefix, which
is the '.../lib/richtext' path. Even though in the above, the base should have
been '.../lib'.

To fix the problem, we add a check to ensure the computed base doesn't have any
sibling directories with the same prefix. If there are, it means 'commonprefix' was
too greedy.
