979723 - (mem-diff) Diff comparison between two complete memory snapshots

Status: RESOLVED INVALID

(DevTools :: Memory, defect)

Description

[Axel Kratel]

As a developer, I would like to be able to compare two different snapshots of the memory heap and see what objects were created and are still reachable (referenced) between the first and second snapshot. 

Acceptance criteria:
- be able to choose from available snapshots
- snapshots should be compatible, i.e. from the same app/unchanged code base, user should not be able to compare incompatible snapshots. 
- The most basic functionality the diff tool should provide is the following:
* show which objects remain reachable
* be able to browse object content
* see changes in the references
* show what references still existi
* show name changes to the object and any object property references
* objects should be grouped with the same available choices as in the real time memory tool.

I believe we have a diff these days. If we want to improve it let's file new bugs that would be more targeted.
