           Summary: Feature request: Tool for tracking down javascript
                    object allocations
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Enhancement
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jon at steelskies.com


I'm working on a fairly complex javascript application at the moment, which is
gaining 600 objects on each xhr request.  I'm really struggling to find out
where those objects are coming from.
Hopefully I'll have fixed this by the time this feature request is fulfilled,
but for those that might struggle with this in future : 

It would be incredibly helpful if there was a debugging tool that would show a
report of javascript objects created between two time points, and show what
objects reference them.  Something along the lines of ObjectAlloc would be
perfect.  I'm not aware of such a tool on any browser - it would be a great
asset to js developers.
