The heap profiler records heap allocations, and exports heap dumps via Chrome tracing.

The code is divided into three directories:

• components/services/heap_profiling/ contains the core logic that records allocations.

• components/heap_profiling/multi_process contains

  • Logic that hooks up processes to the heap_profiling service [depends on content/].
  • End to end tests [depends on content/].

• components/heap_profiling/in_process contains

  • Logic that hooks browser process to the heap_profiling service

• chrome/browser/profiling_host/ contains:

  • Logic that hooks up UI surfaces to the heap_profiling service.
  • Logic to automatically upload heap dumps in the wild.
