956817 - Port preference-based logging control to Log.jsm from Thunderbird's log4moz

Status: RESOLVED WONTFIX

(Toolkit :: General, defect)

Description

[:Irving Reid (No longer working on Firefox)]

A version of log4moz in the Thunderbird code base has preference-based controls. Shall we port this to toolkit/Log.jsm or do we need to bikeshed on the desired feature set first?

There are bugzilla comments somewhere (possibly bug 451283) about my opinions on this. Essentially:

1) Establish convention for defining logging settings via preferences. We can look at services.sync.log for inspiration.
2) Create a JavaScript component that reconciles preference values with Log4Moz loggers and handlers.
3) Create an XPCOM service that watches prefs branch(es) containing logging settings and have it update logging settings in real time.

We're moving towards replacing Log.sys.mjs with console.createInstance (bug 1828156). Both have preference level handling, so I think we can mark this as wontfix.
