Bug 62469 – Fetching a Worker with url that isn't allowed from a file based test causes DRT to crash.

• Component: DOM
• Status: RESOLVED FIXED

[David Levin]

The problem is that this results in a synchronous failure (in ResourceLoaderDelegate.mm, willSendRequest) which results in deleting the WorkerScriptLoader and calling ActiveDOMObject::unsetPendingActivity (before setPendingActivity has been called).

Could be fixed as a separate patch...

The cahnge to xcodeproj file seems unrelated.

The test added by this patch is failing on GTK.  Maybe we just need to add a platform-specific result?

Looks like the GTK DumpRenderTree isn't very good at blocking external network requests!  It's probably hitting the example.com redirect to iana.org on every test run!

That sounds like a really annoying bug for iana.org :(

I suspect they're pretty used to it...  (but we should fix it, of course).

This test is also failing on Windows:

Windows is also failing fast/workers/worker-event-listener.html. I think there is some other issue going on there that a Window WebKit developer could look at.

Addressed http://trac.webkit.org/changeset/88675 (Made it skipped and added a bug for gtk).

After further review, it appears that the other Web Worker failure only started occurring after my new test, so I filed a bug and put it in the Skipped list for Windows (http://trac.webkit.org/changeset/88688).
