Bug 98086 – platform/chromium/virtual/threaded/compositing tests are flaky

• Component: Tools / Tests
• Status: RESOLVED WONTFIX

[Ojan Vafai]

Sometimes crashes. Sometimes gets ImageOnlyFailure. These seem to pass without threaded compositing enabled.

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 ...

whoops, wrong bug

[James Robinson]

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

[James Robinson]

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.

Started crashing again on WebKit Win7:
