Bug 89789 – [Chromium] Layout tests plugins/embed-attributes-style.html and userscripts/user-script-video-document.html failing on Mac

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Plug-ins

[Kenneth Russell]

Support for the QuickDraw drawing model was removed from Chrome in http://src.chromium.org/viewvc/chrome?view=rev&revision=143721 . At that point layout test plugins/embed-attributes-style.html started failing:

Presumably the test plugin is requesting the QuickDraw drawing model. Given that this is the only plugin test failing, I think it should be possible to fix up the test.

Marking the test as a known failure in TestExpectations for the moment.

Hm, this uses the QuickTime plugin, which should use Core Animation and be fine on 10.6+. Oh, but do we run this test binary with OSMesa and thus not have CA support? Or are these tests run in a simplified host that doesn't use Chromium's model negotiation?

If it's the former, maybe we should add wmode="transparent" to the QuickTime embed; that should cause it to use CG mode.

Alternately, it's not clear to me why this test uses QuickTime in the first place, so perhaps the better approach would be to make it use the normal test plugin instead of relying on a specific plugin.

QuickTime simply won't run on 10.5 any more, so this is expected. We should presumably be shutting down the 10.5 testers anyway.

I don't have a WebKit tree set up, and I'm not sure when I'll have to set one up. If someone who does could try changing this test to use the test plugin and see if it works (we'd have to change the expected.png obviously), that would be awesome.

userscripts/user-script-video-document.html has started failing on Win7 debug as well: 

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=userscripts%2Fuser-script-video-document.html

Updating the test expectation for that one, also scoping it to Debug.
