41428 - XBL prototype chain must support forking

Status: RESOLVED WONTFIX

(Core :: XBL, defect, P3)

Description

[David Hyatt]

When bindings are used with differing base classes, the prototype chain between 
the object and the binding whose base class differs must be dynamically forked 
or everything will go to hell really fast.

This is a critical XBL problem.  Probably not nsbeta2, but we can't ship with 
this.

Nominating for mozilla1.0.  This needs to be targeted at a nearer milestone than
Future before too long.

David - could you give us a pointer as to how difficult this would be to fix or 
where to start looking?
It would be really nice to have this fixed for the SVG implementation, so that 
we don't have to duplicate tons of xbl code for every single svg-element.

Can anybody confirm the relation to Bug 190970, please? Or am I just to dump?

[Boris Zbarsky [:bzbarsky]]

What is left to do here now that bug 127418 is fixed?

Comment 8

[Michael Kohler [:mkohler]]

This is a mass change. Every comment has "assigned-to-new" in it.

I didn't look through the bugs, so I'm sorry if I change a bug which shouldn't be changed. But I guess these bugs are just bugs that were once assigned and people forgot to change the Status back when unassigning.

XBL is now disabled in Firefox (Bug 1583314) and is in the process of being removed from Gecko (Bug 1566221), so I'm closing bugs related to the implementation.
