Summary platform/chromium/virtual/threaded/compositing tests are flaky

Reported 2012-10-01 15:57:18 PDT
Sometimes crashes. Sometimes gets ImageOnlyFailure. These seem to pass without threaded compositing enabled. http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=platform%2Fchromium%2Fvirtual%2Fthreaded%2Fcompositing Adding to these to TestExpectations.

Thanks for filing this. I only wish somebody had done it sooner so that the flakiness dashboard would be useful for tracking down when some of this flakiness started. :(

it looks like some of the software compositing bugs on this might be crashing in a way that is hanging the win (dbg)(2) bots, so I'm going to skip the following tests on windows: platform/chromium/virtual/threaded/compositing/webgl/webgl-nonpremultiplied-blend.html platform/chromium/virtual/threaded/compositing/webgl/webgl-no-alpha.html platform/chromium/virtual/threaded/compositing/webgl/webgl-reflection.html platform/chromium/virtual/threaded/compositing/webgl/webgl-background-color.html platform/chromium/virtual/threaded/compositing/webgl/webgl-repaint.html platform/chromium/virtual/threaded/compositing/visibility/visibility-simple-webgl-layer.html platform/chromium/virtual/threaded/compositing/visibility/visibility-simple-canvas2d-layer.html See http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Win7%20%28dbg%29%282%29/builds/3/steps/webkit_tests/logs/stdio for an example where the bot hung. We think we might be triggering windows dialogs on that bot ... See also: http://code.google.com/p/chromium/issues/detail?id=149795

http://trac.webkit.org/changeset/134667 will probably help with at least some of these. Running the suite locally to see...

Removed crash lines in http://trac.webkit.org/changeset/134857. If the tests look stable for the next several runs I'll remove the expectations completely.
