161626 - mozilla can't read pref when the ioservice is initialized

Status: RESOLVED INVALID

(Core :: Networking, defect)

I found a problem in ioservice:init() function. I saw it want to read 
preference file for modify the port list in ioservice:init(). But it seems 
didn't work due to we can not get portlist form preference file. I guess we can 
not read the preferrnce file when mozilla starting ioservice. the below code 
can not work in ioservice:init().

nsCOMPtr<nsIPrefBranch> prefBranch;
221     GetPrefBranch(getter_AddRefs(prefBranch));
222     if (prefBranch) {
223         nsCOMPtr<nsIPrefBranchInternal> pbi = do_QueryInterface(prefBranch);
224         if (pbi) {
225             pbi->AddObserver(PORT_PREF_PREFIX, this, PR_TRUE);
226             pbi->AddObserver(AUTODIAL_PREF, this, PR_TRUE);
227         }
228         PrefsChanged(prefBranch);
229     }

mozilla can support customer editing portlist.  But sometime, customer change 
the pref.js for making mozilla to open/block some port. The function must let 
ioservice read perf for change portlist when the ioservice is initialized. But 
ioservice can't read pref when the ioservice is initialized. So the customer 
still couldn't change the ioservice's portlist.
Expected Results: The ioservice can read pref when the ioservice is initialized

reporter: When the ioservice is initialized, the user's profile has not been
selected, and the user's prefs.js file has not been read, so we cannot get the
portlist from the preference file. But once the preference file is read, it
notifies all its observers, and the ioservice is able to read the prefs.
