Benchmark results

Benchmark results look neutral.

[Keith Miller]

Failing tests are kosher. The cross domain issues are just because we are attempting to get the Symbol.toStringTag from a different window and should be blocked anyway. I'll update the expected files.

Looking.

[Keith Miller]

Test failures should be fixed in <http://trac.webkit.org/changeset/191821>. I forgot to mark those tests as passing.

Cool. Thanks for taking a look!

32-bit JSC tests have been failing with strange crashes every time after this patch:

https://build.webkit.org/builders/Apple%20Mavericks%2032-bit%20JSC%20%28BuildAndTest%29/builds/13823/steps/webkit-32bit-jsc-test/logs/stdio

I'm going to try rolling out to see if that helps.

Re-landed in r191864, as this wasn't the culprit. I wonder what was!

Re-landing this did introduce test failures.

Regressions: Unexpected text-only failures (3)
  http/tests/history/cross-origin-replace-history-object-child.html [ Failure ]
  http/tests/security/cross-frame-access-custom.html [ Failure ]
  http/tests/security/cross-frame-access-object-setPrototypeOf.html [ Failure ]

I think this may have to be rolled out after all. Could someone please investigate?

[Darin Adler]

And EWS shows those same failures, so we should not have ignored them in EWS!

[Darin Adler]

Oh, wait, you say those failures are actually progressions.

My new question then is: Why haven’t the new expected results been landed yet?

[Darin Adler]

Looks like when Alexey re-landed in r191864, the changes to http/tests expected results didn’t land.

[Darin Adler]

I tried to fix things in http://trac.webkit.org/changeset/191869
