+sergeyberezin to be sure, since the Infra>Flakiness>Dashboard component doesn't seem to have any default owner (but maybe it's triaged anyway?).

I think you meant the other Sergiy, who has been working with this code recently. (changed on the cc line)

Sergiy is out this week but if you want to send me a CL to add chromium.webrtc.* here:
https://chromium.googlesource.com/infra/infra/+/master/go/src/infra/appengine/test-results/masters/masters.go

I will approve it and deploy it and we can see if that fixes it. Do you see the upload steps on the builder already?

Thanks Erik, you're right.
I created https://chromium-review.googlesource.com/422773 for the test-results change. I don't see any separate upload steps on our bots, so I can look into updating the recipes for that once the server-side change is landed + deployed.

Deploying #4 to prod.

Looks like the masters are still not listed in the list of builders on https://test-results.appspot.com/dashboards/flakiness_dashboard.html for browser_tests. Looks like results are not being uploaded, so there is more work to be done on this bug.

Right, I mistakenly assumed it would just work when whitelisting the master. 
I'll make sure the missing steps are added to our bots.

Well, that was useless it seems. 
We still have perf tests in browser_tests and content_browsertests binaries, so we have to have perf reporting enabled. That however (correctly) prevents us from enabling flakiness dashboard reporting for these tests (https://cs.chromium.org/chromium/build/scripts/slave/recipe_modules/chromium/api.py?rcl=0&l=338) so I guess to get this we first need to finish our work moving these tests out of there.
Marking this as fixed since what we asked for here is done. Thanks!

It wasn't useless, since otherwise Test Results Server would be ignoring data uploaded from chromium.webkit.fyi master. But o'course you'd need to actually upload the data to see the results on the Flakiness Dashboard.
