Description Mikhail Naganov 2010-12-03 20:12:05 PST
The current heap snapshots doesn't provide enough data for comfortable leaks hunting, e.g. it's impossible to identify the exact object that retains too much memory, or point out object instances that were created since the last snapshot taken, also it's impossible to determine, what are the names of the properties that hold an object.

I'm working on the new version of heap profiler that provides those richer capabilities. We create a detailed snapshot of JS VM heap containing each individual object, and provide processing tools in Inspector.

The first commit was this one, providing JSON transport for heap profiles: https://bugs.webkit.org/show_bug.cgi?id=49974
