Bug 31838 – Nested start/stop events in dispatchDidChangeLocationWithinPage for pages that do fragment redirect in window.onload

• Component: WebKit API
• Status: RESOLVED FIXED

[xiyuan]

Start/stop events are generated in dispatchDidChangeLocationWithinPage for WebView delegate. Currently they are generated regardless whether a frame is is loading or not. This causes nested start/stop events being fired when dispatchDidChangeLocationWithinPage happens from a fragment redirect in window.onloader handler.

Attached patch makes the start/stop events only being fired when the page's main frame has stopped loading to avoid such situation.

nit: please link to the bugs.webkit.org bug instead.  that bug can have a reference
to the chromium bug if you think it would be helpful.

also, you need to include a modification to WebCore/ChangeLog.  please see the

Is it because my diff is from git?

I have no idea why the cq failed here.  Let's spin again and see if it fails a second time.  If it does, then I'll try to debug why.

Previous patch is rejected by commit-queue bot because my base ChangeLog is too old and the bot failed to patc. I have updated the patch and hopefully it works this time.
