Raise priority

 Issue 888663  has been merged into this issue.

martiniss would you be able to triage this?

This is currently blocking my work...  Is there any alternative to flakiness dashboard that people are using in the meantime?

I think sean should know more about what to do here.

What are you trying to do? You can view individual results for layout tests if you need that.

Thanks! I have reports that a layout test is flakily timing out. I'd like to see whether the timeouts are due it to just being generally slow and occassionally crosses the timeout threshold or whether it clearly gets stuck sometimes. I also want to see if a related test is also timing out.

It looks like "webkit_layout_tests (with patch)" might be working:
https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=webkit_layout_tests%20(with%20patch)&tests=navigation-redirect

I see. Yeah, there probably isn't really a way to diagnose that apart from this page.

I think there's an easy fix for this problem; let me try to make a CL.

Yeah, there's some specific code which is breaking because of the literal string "webkit_layout_tests". The with patch version is run on tryserver, so if the layout test is timing out on the CQ, you can diagnose that with the data you're able to look at.

test-results: Check for extra builders before loading

There's a bug in code which was landed one year ago, which apparently never
got noticed or exposed until now. Check if we have extra builders before
trying to bind them.

Ok, the CL in #12 didn't fix this. There are several other conditions which still seem to break.

sergiyb@, you added this code originally, and have TODOS assigned to you in the code. Can you fix this?

I've changed teams and don't support flakiness dashboard anymore. Shuotao's team should be able to find an owner for this.

I uploaded a second CL which I think actually fixes this. https://crrev.com/c/1246473

test results: Remove layout tests special casing

Effectively reverts https://crrev.com/c/586720. It looks like
webkit_tests doesn't get uploaded to the flakiness dashboard anymore, so
this should be unneeded.
