Bug 48368 – Update ProgressTracker when moving a frame between documents

• Status: RESOLVED
• Resolution: FIXED
• Component: Page Loading

[Jenn Braithwaite]

When a live iframe is moved to a different document via adoptNode, the frame's resources are still being tracked by the former page's ProgressTracker.

When a resource load is transferred to a different document/page, the ProgressTracker should treat that item as being completed.  (Decrementing the progress of bytes received seems wrong.)

Need more study to determine how the new page's ProgressTracker is affected by the resource load being transferred to the new page.

If someone knows of a way to test this from JS, I'm all ears.

Looks good!
One small iteration...

> WebCore/loader/ResourceLoadNotifier.cpp:167
> +    oldPage->progress()->completeProgress(identifier);

Could we add ASSERT documenting that new page and old page are guaranteed different here? This code actually uses this assumptions (because otherwise it immediately deletes the just-transfered 'identifier' from the progress tracker).
