We do have a convention of listing owners for imported WPT directories, eg. pointerevents is listed as "Owners: mustaq@chromium.org" today: https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/W3CImportExpectations?q=W3CImportExpectations&sq=package:chromium&dr&l=291

We've talked about auto-filing bugs for new failures in directories listed as "owned".  I think that (or at least sending a notification e-mail) would be a good idea.  qyearsley@ what's your current thinking here?

For generic notifications of changes, I think it's simplest if people just subscribe to the upstream OWNERS files.  That'll be more timely and give you a link to contribute directly to the PR conversation on GitHub.

Currently the w3c-test-autoroller uses a JSON mapping of some test directories to owners (https://cs.chromium.org/chromium/src/third_party/WebKit/Tools/Scripts/webkitpy/w3c/directory_owners.json) to decide who to CC when auto-importing, and AFAIK that works now (for those directories with owners in that file). But that file isn't up to date, and isn't based on the "Owners" lines in W3CImportExpectations, so I think we need to improve our solution to make sure that the owners map is always kept up to date.

I still think that auto-filing bugs for new failures is likely be a good idea, although care should be taken to make sure it's not too noisy (e.g. we probably don't want a separate bug for every single individual test, and some for some newly-imported tests with -expected.txt files, we may not necessarily want to file a bug; in previous discussion (when the interns were here), we talked about filing one bug per directory upon importing, and only for directories that had opted-in to auto-bug-filing.

That said, w3c-test-autoroller still hasn't had a very long streak of successes, and there are probably other issues to fix first :-/

rbyers@' suggestion to subscribe to upstream OWNERS files sounds like a good idea for keeping up with changes in general. Although this won't tell you directly whether tests are now failing in Blink.

The related bug for auto-filing bugs for new failures is:  bug 626529 .

Thanks Quinten, that's great!

Ideally we'd have just one place that lists the WPT directories we care about, and who in the project cares about them.  Perhaps we could eliminate W3CImportExpectations entirely and rely just on directory_owners.json to indicate what directories to import (after updating to match our current list of course)?
