457746 - mChannel can be bogusly null in XMLHttpRequest

Status: RESOLVED DUPLICATE of bug 390219

(Core :: DOM: Core & HTML, defect)

Description

[Boris Zbarsky [:bzbarsky]]

We reset mChannel when we get OnStopRequest, but we aren't verifying that it's OnStopRequest for the right channel.  So in a testcase like this:

      var xhr = new XMLHttpRequest();
      xhr.open("GET", uri);
      xhr.send("");
      xhr.abort();
      xhr.open("GET", uri);
      xhr.send("");

we will null out mChannel once we get OnStopRequest for the first channel, and after that get various things wrong about the second channel....  Testcases and patch hopefully coming up soon.

Nevermind.  This was branch-only.

I checked in a test for this too.
