Bug 165170 – Web Inspector: Improve name sorting in HeapSnapshot data grids

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

Summary:
Improve name sorting in HeapSnapshot data grids

Steps to Reproduce:
1. Inspect this page
2. Take a Heap Snapshot
3. Drill into Heap Snapshot > Object Graph
4. Expand Window object
5. Sort by "Class Name" column
  => Sorting is difficult to follow. Named properties are mingled with unnamed (internal) properties.

A better sort would be grouping named properties and unnamed properties:

  - Sort named properties by their property name (property names will be unique if they exist)
  - Sort unnamed properties by their class name (guaranteed)
  - Sort any tied class names by their object id

Now "Class Name" becomes an ambiguous DataGrid column title in Object Graph, so rename it to just "Name".

This sort will improve the "Class Name" sort in both the Instances view and the Object Graph, because we fallback to sorting by object id in ties.

Was this screenshot taken before the column rename to "Name"?

Nope, the Instances view keeps the name "Class Name". Only the "Object Graph" one changed to "Name". Do you think it would make sense to change both to be "Name"?

I think they should both be "Name", since the column has a mix of class names, property names, etc.
