933026 - (rec-JS-mem-prof) Recorded JS Memory Profile

Status: NEW

(DevTools :: Memory, defect, P3)

Description

[Axel Kratel]

As a web/app developer, I would like to be able to analyze the memory profile of my application:

Acceptance Criteria:
- Only my app memory profile is included
- Can see all of the JS Globals and DOM nodes 
- sortable by type
- sortable by counts
- sortable by number of references
- sortable by total size.

Note: this story corresponds to the classic object profile. 

May require User story splitting along DOM versus JS object/nodes.

From bug 625846#c13 - ability to sort by file the constructor is defined in.

According to Fitzgen, if we enable allocation tracking during recording (should use a refresh after recording), we can also have allocation sites as well

I think we only miss this part for now: "Can see all of the JS Globals and DOM nodes"

Or rather we can see the DOM nodes but not their size yet. We have a bug for this but I don't have it at the moment, so I'm gonna keep this bug open for now.

bug 1474383 is the one I was talking about in comment 2.
