805531 - Turn off javascript.options.mem.log for b2g

Status: RESOLVED FIXED

(Firefox OS Graveyard :: General, defect)

Description

[Dave Hylands [:dhylands]]

Currently, in Firefox OS, one of the largest polluters of the console log are these messages:

CC(T+65519.1) duration: 17ms, suspected: 58, visited: 995 RCed and 1644 GCed, collected: 0 RCed and 0 GCed (0 waiting for GC)
ForgetSkippable 3 times before CC, min: 1 ms, max: 1 ms, avg: 1 ms, total: 3 ms, removed: 200

ForgetSkippable 3 times before CC, min: 0 ms, max: 1 ms, avg: 1 ms, total: 3 ms, removed: 211

These messages are controlled by the javascript.options.mem.log pref, which is set to true in b2g/app/b2g.js.

We should disable this by default, since most people (that I'm aware of) find these messages annoying.

fabrice suggested that I get aurora approval, so I'm doing that.

This particular patch only affects b2g.
