Bug 19467 – Hard crash when dragging (enabling) modules on this page

• Component: JavaScriptCore
• Status: RESOLVED DUPLICATE

[Alex Suraci]

I've allowed Guests to enable/disable modules at this URL so that you can see the crash firsthand. I am on nightly WebKit r34469, but this crash may have existed before.

There are unrelated errors in the console log (they're from drawing those conflict lines), I think you can ignore those.

The JavaScript related to this is the function "extend_draggables" at http://chyrp.net/webkit/includes/admin.js.php?action=extend_modules . I've narrowed down the crash to using the "action" variable in the callback function for $.post. The "type" variable is also affected, but it doesn't cause a crash. For some reason its value is assigned to "-498531038".

[Alexey Proskuryakov]

Confirmed with r34478.

[Mark Rowe (bdash)]

<rdar://problem/6007106>

[Cameron Zwarich (cpst)]

It seems that this works even in the 34503 nightly and onward. Alex, can you confirm this? Even if it is fixed, I may want to find the exact revision that fixes it and ensure that we have adequate test coverage.

[Alex Suraci]

I tested from 34503 and onward and it only works in the latest, 34753. :)

[Cameron Zwarich (cpst)]

You're right. If I play around with it long enough in earlier nightlies, I can get it to crash, although not always as easily as the first time I tried. Do you have something specific that always works?

I'll try to narrow down the exact revision, but if it only works in the latest nightly I have a pretty good idea of what fixed it.

[Alex Suraci]

I was just dragging things over to "Enabled". I was dragging Cacher (and sometimes Markdown), if that matters.

On another note, I'm fairly certain that it's not the actual dragging that's causing the crash, but the redrawing of the red conflict lines. That part's fixed in later versions of this software and it works fine, with no crash. Regardless, having the browser crash is still less than optimal.

[Cameron Zwarich (cpst)]

I can reproduce this consistently with nightlies before r34753 by right clicking when I stop dragging. It works in r34503, so the likely fix is r34751, which fixed bug 19716.

If I understand the code correctly at first glance, the drop function is called directly by native code as a callback on an event. Can you confirm this? I don't know much about jQuery. The actions variable is referenced by the $.post function, so if there was an exception during the callback that unwound to the top (which it seems likely, since there are lots of errors on the console), this would be an instance of bug 19716.

[Alex Suraci]

Yes, it is a callback used when dropping the draggable.

[Cameron Zwarich (cpst)]

Marking this a duplicate of bug 19716. Thanks for reporting it, Alex!
