952198 - Support SOW for proxy bindings

Status: RESOLVED DUPLICATE of bug 825392

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

Description

[William Chen [:wchen]]

I'm hitting this assertion when trying to access a select element in anonymous content:
http://mxr.mozilla.org/mozilla-central/source/dom/bindings/BindingUtils.h#518
IsDOMClass(js::GetObjectJSClass(obj)) && !(js::GetObjectJSClass(obj)->flags & JSCLASS_DOM_GLOBAL)

The select element has a proxy binding, it looks like I'm hitting the issue mentioned here:

This requires that we either free up the expando slot by moving the same-origin expando object into the Xray expando linked list, or that we make proxies like normal objects by moving the handler into the JS class (but that seems like a longer term project).

efaust actually has patches for the latter, pretty much.

But also, I thought bholley was trying to kill off SOWs.

[Bobby Holley (:bholley)]

If we're going to spend any engineering effort on SOWs, it should be to remove them. This is bug 825392.
