Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=202872

[dmichael (off chromium), 2013-05-29 15:17:13]

Committed patchset #1 manually as r202872.

[eseidel, 2013-05-29 19:22:33]

It looks like this is a new failure:
http://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=...

Unclear why this isn't caught by the Chromium CQ, since all Auto-Rolls go
through teh Chromium CQ.

Also, I should probably figure out what I need to do to get Drover to auto-CC
the gardeners when making a rollout.  I committed the rollout, but my account is
just being used by a bot here. :)

Here is a clean run of the interactive_ui_tests:
http://build.chromium.org/p/tryserver.chromium/builders/mac_rel/builds/132591...

Looks like this didn't fail in teh try-jobs, but did on teh tree?

Did we decide the roll was actually at fault here?

It rolled again, and the Mac bots all failed again in the same way:

http://build.chromium.org/p/chromium.mac/buildstatus?builder=Mac%2010.6%20Tes...
http://build.chromium.org/p/chromium.mac/buildstatus?builder=Mac%2010.7%20Tes...

So I have a hard time discounting this as a fluke.

[eseidel, 2013-05-29 19:35:45]

It looks like this only fails on mac, and only on debug, is that correct?

I suspect the CQ doesn't test debug configs (I'm not sure that it should).

[eseidel, 2013-05-29 19:37:12]

http://src.chromium.org/viewvc/blink?view=rev&revision=151373 appears to be the
only change in that roll which looks even possibly related to this.

[eseidel, 2013-05-29 19:39:01]

https://codereview.chromium.org/15797008 is the second roll-revert, btw.
