Need to extend DumpRenderTree to expose number of worker threads

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Andrew Wilson]

There's currently no way to track if/when worker threads actually shut down from javascript layout tests.

We need to extend DumpRenderTree to expose this information so we can write layout tests to verify this functionality.

proposed patch

Turns out adding new APIs to WebKit is trickier than it appears. We need to put together a wiki page on this.

Wow.  I'm just blown away by how thorough this change is.  Really, wow.  I don't think I would have had the stamina to change all 4 platforms like that.

This is technically a style violation:
 32         if (layoutTestController.workerThreadCount == 1) {
 33             log("PASS: Worker thread created");
 34         } else {
 35             log("FAIL: After thread creation: layoutTestController.workerThreadCount = " + layoutTestController.workerThreadCount);
 36         }

As far as I can tell, this all looks correct.  I'm certainly no COM expert, so there could be errors there, but looks fine to me.
