#178 closed defect (fixed)

Deal with missing frame URL gracefully

Adblock Plus for Chrome 1.7.4

How to reproduce


Observed behaviour

isWhitelisted() calls stripFragmentFromURL() with a null frame URL which causes an exception. In future Chrome versions that exception will cause the request to be cancelled.

Expected behaviour

isWhitelisted() should ignore frames without a URL. It might also be a good idea to check why we have a null frame URL in this scenario and whether there is some issue with our frame tracking code.

This currently happens when encountering an unknown frame in an unknown tab. However considering that this is a Chrome-specific issue and that isWhitelisted() isn't the only case where unknown frames break our code, it should rather be handled into the abstraction layer.

This was already fixed properly with, by retrieving existing frames at startup, and ignoring frames that are still unkown.

Even if my proposed solution isn't optimal, that doesn't make the issue itself invalid ;)

It merely means that it will be resolved by this review. Reopening.
