Bug 46154 – XMLHttpRequest.open() in iframe fail in some tests

• Status: NEW
• Component: XML

[Jian Li]

XMLHttpRequest.open() in iframe fail in some tests. Not sure if there is a bug in XHR code or in the tests.

Tests:
http://tc.labs.opera.com/apis/XMLHttpRequest/open-url-multi-window-2.htm
http://tc.labs.opera.com/apis/XMLHttpRequest/open-url-multi-window-3.htm

This is a consequence of WebCore's network stack depending on Frame.  There was a recent webkit-dev thread about directions for fixing this architectural problem.

It's not clear to me why these requests are supposed to run to completion. Stopping XMLHttpRequests whose opener frame goes away seems to be a good thing in general.

We are still failing some of these test cases (though doing better than other browsers):

1) open-url-multi-window-6.htm
2) open-url-multi-window-3.htm

Direct Links to test below:

Link - http://wpt.live/xhr/open-url-multi-window-3.htm
Link 2 - http://wpt.live/xhr/open-url-multi-window-6.htm. (Timeout - Pop-up Blocker kicks-in)

Just wanted to share updated testing status. Thanks!
