Thanks.

The explicit call to PassRefPtr<DOMWindow> shouldn't be necessary here.

I just copied it.  I'll move it. 

It looks like there were some new IDB bugs recently introduced, so this patch is failing 4 idb tests. Should I disable the tests in chrome and file a bug for someone to fix that or wait for fix before committing this?

We should see what jsbell and alecflett would like you to do.

It looks like there are also some LayoutTests that fail with your patch.

I added blocking bug 101725 which describes the problem and offers an ugly potential solution.

The 4 inspector/indexeddb tests that are listed above?

I've cc'd vsevik on this bug.

The inspector's IDB code was just rewritten to talk to the front-end APIs rather than the back-end APIs which may have introduced the problem, given that it will be calling into IDB APIs without necessarily having V8 on the stack.

added CRASH instead of ASSERT when no context is entered and UseCurrentWorld is called

Looks like this comment still applies to the final patch.

Yeah, I had to rebase that patch by hand and didn't see it.

I don't think it is fixed. The test still fails both on bots an on my local build.
