Description Chris Dumez 2012-05-04 05:21:55 PDT
The media/video-poster-blocked-by-willsendrequest.html test is flaky on the EFL build bot.

It appears the flakyness is caused by media/crash-closing-page-with-media-as-plugin-fallback.html:

This succeeds:
./Tools/Scripts/run-webkit-tests --efl -p media/video-poster-blocked-by-willsendrequest.html

But this willl cause media/video-poster-blocked-by-willsendrequest.html to fail:
./Tools/Scripts/run-webkit-tests --efl -p LayoutTests/media/crash-closing-page-with-media-as-plugin-fallback.html media/video-poster-blocked-by-willsendrequest.html
Comment 1 Chris Dumez 2012-05-04 05:24:05 PDT
This is related to the poster parameter of the video tag because the following removes flakyness:

Same flakyness seems to happen on Lion (Bug 82976)

Patch

The issue was caused by the fact that media/crash-closing-page-with-media-as-plugin-fallback.html and media/video-poster-blocked-by-willsendrequest.html use the same PNG file as poster attribute in the video tag. The PNG file gets cached when the first test is executed and this somehow causes the second test to fail. I addressed this by clearing the caches between the tests in DumpRenderTreeChrome::resetDefaultsToConsistentValues().

The tests are no longer flaky.

BTW, it'd be awesome if you could add the explanation in comment #3 to the ChangeLog.
