Somebody may be able to provide clue here and save me a deal of time...
I'm intending using DO between a Foundation Tool and what is currently
a normal Cocoa app. I have used DO before between 2 normal Cocoa apps
(i.e. where NSApplication starts the run loop etc.) - that just worked
first time with no problems, but a Foundation App probably needs a
little more TLC.
Right now, I have some test code in my 'main' function that attempts
to connect to a remote object. This seems to be able to produce an
NSConnection (I provide a sendPort configured with IP and port of the
remote socket/NSConnection, and receivePort is nil).
However, when I attempt to get the 'distant object' proxy, the call
never returns.
I'm trying to figure out how to get a handle on what's happening here,
and there are a bunch of questions to work on:
1. If you manage to get a connection instance, does that mean the
connection is established correctly?
2. What runloop apparatus do I need to have various pieces of this work?
So far, regarding (1), I have tried to connect to arbitrary ports on
the remote machine, and indeed get different (expected) behaviour: an
NSPortTimeoutException. So, I have reason to believe that when the
NSConnection instance is returned, things should be set up correctly.
I'm beginning to think that (2) is where the issue lies. I've read
that replies use a special NSConnectionReplyMode, and that might also
explain why I can't even get the NSDistantObject from -[NSConnection
rootProxy] at this time (because I run a runloop at the bottom of my
main function).
Anyway, while I fiddle with trying to find a magic incantation and
particularly, how I should configure my runloop in a foundation app to
get DO to work (and then where it will work), someone might already
have some insight into how to get this going.
Cheers
