Part 2 - nsIUrlClassifierDBService.lookup() takes principal

Review of attachment 644098 [details] [diff] [review]:

Seems reasonable. It is not good that we do not have any tests that actually check to ensure that the data is being isolated on a per-app-ID basis though. I guess that is the case for the other related changes too. What's the plan for testing that?

This needs to use the innermost URI.

Why are we not checking the return value here.

I bet this is a common pattern in callers, so TestPermissionFromPrincipal and related Test* functions should be made to set the value of *perm to the safest possible value (permission not granted).

nit: (void) since you are ignoring the return value.

Part 1 - nsIURIClassifier.classify() takes a principal

Review of attachment 644096 [details] [diff] [review]:

Again, seems reasonable but we're not actually testing the intended effect of this change; we're just testing that we didn't break the existing functionality.

check return value or (void) if GetURI is infallable.

I am not a toolkit reviewer, so CCing dolske so he's aware I'm playing in his yard.
