Can I get a test log link for the failing test?

Looks good overall; r- for a couple of relatively minor issues. Unfortunately I don't think it's possible to get the full test logs off the EWS bots; if you haven't already, build DumpRenderTree in your Chromium workspace and use src/webkit/tools/layout_tests/run_webkit_tests.sh to check the expected results. I'm doing this now and will update this bug if anything turns up.

4 space indent. (Style queue should have caught this.)

Please split this change off into a second bug.

I ran the tests locally with the default Mac bindings (whatever that's called, the one which runs WebCore under the Safari shell).

Will fix that (the style checking script didn't actually catch it).

Will do.

I split the second part of the patch to bug 77462.

Looks good. Let's see what the Chromium EWS bot has to say before cq+'ing it. r=me

The problem is in the test of getSupportedExtensions()' return value; if the implementation had a different number of extensions then the output would be different. I've updated the Khronos version of the test; please update the copy of the test in this patch and its expectations.

[Ehsan Akhgari [:ehsan]]

Good catch!  What is the Khronos rev id which fixes this?

[Kenneth Russell]

It's Khronos r16797.

Let's wait for it to clear the EWS bots before cq+'ing it.
