1502917 - Adding ChromeUtils.RequestProcInfo()

Status: RESOLVED FIXED

(Core :: Widget, enhancement)

Description

[Tarek Ziadé (:tarek)]

Adding a function that returns Firefox processes info.

The work in done in two layers:

- a new platform-agnostic module in widget/procinfo that returns info on a process given its pid
- a Chrome util function that iterates on processes started by Firefox and use procinfo to collect info

This function can be used to collect Firefox' processes behavior over time.

The platform agnostic function will be developed only for Linux/Win32/macOs for now and might be extended later to support all OSes flavors Firefox currently supports.

RE: discussion in mozlando, about adding proc/thread info. Especially interested in getting any thread info for web assembly! But starting with any level of thread info is great.
