I just looked at Apples latest NSWorkspace documentation, and see that, as of 
MacOS 10.3 they have a new method to launch applications, which provides more 
fine control over the way that the application is launched ... perhaps we 
should be implementing that?

Summary:  Duplicate application launching

Original Submission:  If I launch an application, that is already running, i 
get an alert panel asking me about renaming, ignoring or aborting. I would 
expect that the existing application instance will be activated instead. So the 
behaviour should be: If there is already running application, activate it, if 
there is not, launch it.



Btw. are there any situations, where one would like to have two instances of 
one application open? How are they compared to the usual situations?



>From the point of user, I consider this to be a bug. Moreover, it is another 
>additional confusion.

I'm still confused about what the problem is supposed to be.

When I use the NSWorkspace method to launch an application which is already 
running, it does not attempt to launch a duplicate copy (though neither does it 
make the existing copy active ... I think it should - a simple message to the 
running application to activate it should fix this).



When I launch a new copy by directly excuting it (rather than via the 
NSWorkspace API) it *does* launch a duplicate copy ... and I think that's 
correct behavior ... certainly it's what NeXT/QApple do too, and makes sense to 
me ... I can't see a reason for preventing people having multiple copies of an 
app runing if they want to.



The alert panel raised when launching duplicate copies is a hack we added many 
years ago, before the NSWorkspace code was implemented, and before gopen and 
GWorkspace were available to allow users to launch apps using the NSWorkspace 
API.  I think this could probably be removed now ... so when you launch 
duplicate apps intentionally, you should not longer get a warning, and the new 
copy of the app should just start up normally.



So ... I see two things to be fixed:

a) activate running app if we call the api to launch it.

b) remove the alert pan el when multiple copies are run.



but I don't actually know of any occasions where we get duplicate copies of an 
app launchd and we shouldn't.

Beeing there, you could take a look also at the bug #4410 that is probably 
correlated :-)

Matt Rice and I have been looking at the duplication issue too. We have a patch 
that fixes it, and currently I'm Thinking Really Hard about whether it's the 
Right Thing.

Alex M. applied something in cvs for me which I believe should 

fix this.

where connecting to the running application would fail in some

cases (see ChangeLog)



though i'm not seeing the ordering front of the clicked on application and 
haven't tried the keyboard modifier, I'm guessing those cases should be handled 
in GWorkspace

I'm not sure what context you are referring to (ie what application launching 
mechanism you are talking about).



Certainly I like the behavior the NeXT workspace used to haver, where double 
clicking on an application in the workspace would simply bring the app windows 
to the front if the app was already running, but a keyboard modifier would 
force the launch of another copy of the application.

I see that as an issue for the workspace manager ...

If it uses the NSWorkspace method launchApplication:shoiwIcon:autolaunche: the 
behavior should be the one we like.  Are you saying that there are 
circumstances where this method does not work properly?

Or are you talking about some other situation entirely?
