We should make a reproducible case that's not internal.

> Source/WebCore/loader/cache/CachedResourceLoader.cpp:482
> +#if PLATFORM(CHROMIUM) || PLATFORM(MAC)
>      // FIXME: Temporarily leave main resource caching disabled for chromium, see https://bugs.webkit.org/show_bug.cgi?id=107962
>      // Ensure main resources aren't preloaded, and other main resource loads are removed from cache to prevent reuse.

Please add a comment about Mac here.

The patch landed here fixed the bug so we need to investigate further and come up with a reduction.

It appears that WebFrameLoaderClient::dispatchDidFinishLoading or  WebFrameLoaderClient::dispatchDidFailLoading is called with identifier of 0.

5 tests started failing on Mountain Lion WK1 Release tests in between 141305 and 141310:

http://build.webkit.org/results/Apple%20MountainLion%20Release%20WK1%20(Tests)/r141310%20(6314)/results.html

http/tests/inspector/resource-har-pages.html
http/tests/loading/redirect-methods.html
http/tests/misc/link-rel-icon-beforeload.html
http/tests/misc/favicon-loads-with-images-disabled.html

Especially for the first one, this change seems very suspect

All of those (except resource-har-pages.html) are expected to change, given that their results depend on the feature disabled in r141306. It's probably best to just expect them to fail until main resource caching is re-enabled.

Marked them as expected failures in platform/mac’s TestExpectations:
http://trac.webkit.org/changeset/141469

[Jessie Berlin]

Actually, http/tests/inspector/resource-har-pages.html was changed in the checkin that enabled this feature:

http://trac.webkit.org/changeset/141136

I am going to mark it as failing for now as well.

Has anyone had a chance to test whether this suite still fails since http://trac.webkit.org/changeset/141615 landed (with main resource caching re-enabled)?

Yes, r141615 fixed the PLT when main resource caching is enabled. My plan is to post a new patch that reverts r141306. Sorry I got distracted by other work.

No problem, I just wanted to make sure there weren't other regressions blocking re-enable :)
