175868 - Allow multiple instances of Mozilla to run (with different profiles)

Status: VERIFIED FIXED

(Core Graveyard :: Profile: BackEnd, defect)

Description

[Steve Dagley]

Now that we support locking of a profile there's no reason we should prevent
multiple instances of Mozilla from launching.

I take it you'll get rid of this resource:

Do we have per-profile locking in CFM that we know works?
Are there other non-profile files (e.g. Global.regs, Application Registry) that
don't use file locking, and need to if we allow the user to run several builds
at the same time?

Comment 5

[Steve Dagley]

Simon suggested the following scenario and I tested it which reveals at least
one problem with the Application Registry when running multiple Mozilla builds:

1) launch Mozilla build A and select a profile
2) launch Mozilla build B and create a new profile
3) quit Mozilla build B
4) quit Mozilla build A
5) launch Mozilla (either build) and note that the profile created in step 2 is
not listed

True, but all other platforms would suffer the same problem and it's not been
reported as of yet. I'll file a bug on that since it's a separate (and XP) bug.
 But, since it's an obscure one, I don't think it should block this patch.

I too think that the failure case described here is rare, and hopefilly will not block others from enjoying this feature. let's pcommit the proposed patch.

Checked in

[Peter Lairo]

So to launch mozilla a second time, the user just doubleclicks the mozilla icon
on his desktop? If not, how is it done?

Would be a pitty to have a feature that no-one knows how to use. ;)

This is a feature targeted mainly at developers.  It doesn't mean you can have 2
copies of the same app binary running.  It means you can have Netscape 7.x or a
Mozilla release build running and also run a debug build you want to test
without quitting the other apps.
