• Status: REOPENED
• Component: New Bugs

TestWebKitAPI.Fullscreen.Delegate is consistently timing out on macOS Debug bots, and appears to be flaky on macOS release bots.

        _RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL.

Patch looks good. A better patch would audit all of the unit tests and fix this up. For future thought, design to prevent this kind of mistake or detect it.

This ok as-is. No change needed. Optimal solution would use auto.

Ditto.

Ditto.

Ditto.

Indeed. This was the result of a minor audit itself.

Okay, for the sake of expediency, I'm not going to update these all to use auto at this time. 

Thanks!

Sadly, this has not resolved the timeouts on the bots.

Reopening since it isn't fixed.

Disabled the test in https://trac.webkit.org/changeset/261243/webkit to get the bots to green.

Specifically, I disabled the Fullscreen.Alert test since it was causing the subsequent test to fail.
