28292 - pref enumeration can go into an infinite loop

Status: VERIFIED FIXED

(Core :: Preferences: Backend, defect, P3)

Description

[(not reading, please use [e-mail] instead)]

i just found this out:

I have some default prefs (in mailnews.js) that I'm trying to iterate through
and migrate.

my PrefEnumerationFunc gets all prefs that matches "ldap_2.server.*.description"
and tries to set those prefs to a migrate value.

this causes an infinite loop, it looks like setting a default pref (thus making
it appear in the users prefs.js) causes the problem.

to reproduce, you're going to have to write some code.  I changed the code I 
wrote (to work around this bug).

try to write some code that enumerates over all the 
"ldap_2.server.*.description" prefs and tries to set them in the enumeration 
call back.

I'm not sure if it happens on all platforms, but I would suspect that it did.

this is not a beta blocker, so if you have beta bugs, work on those first.
