Description Alexey Proskuryakov 2015-08-31 09:51:18 PDT

There are currently many timeouts on Web Inspector tests. The failures follow a similar pattern:
- on Mavericks Debug, the tests rarely time out, but have uneven performance, jumping from ~2 seconds to ~20 seconds;
- on Yosemite Debug and Leaks, they also have the uneven performance, but also frequently time out.

These tests fail so frequently that they make the dashboard red all the time. I'll add test expectation now.

Added expectation in http://trac.webkit.org/r189171

Ugh :( Joe and I hope to get this diagnosed during this week. I'll start investigating with the involuntary AppNap idea.

Comment 3 Alexey Proskuryakov 2015-09-06 23:23:45 PDT

Added inspector/indexeddb/requestDatabaseNames.html in r189459.
