Re: [Swingosc-devel] "failed to start" message

[James H. <jam...@gm...>]

I think I see what the problem is. I put in some debugging statements 
this morning, and found that the line "cancel.stop" is not guaranteed to 
prevent the cancel action from running.

SwingOSC : server connected.
swing updatelistener: is running: true
stopped cancel thread

// later:
cancel thread awake

^^ Whoa!! That last line shouldn't happen.

My suggestion, if you don't like the conditional inside 'cancel', is to 
use a Task instead of a routine. If it's a Task, "cancel.stop" will set 
the task's stream variable to nil. The task remains in the scheduler 
queue, but when it wakes up, it looks to 'stream' to know what to do and 
finds nothing.

That is, replace the current 'cancel' assignment with this:

             cancel = Task({
                 timeout.wait;
                 upd.remove;
                 "SwingOSC server failed to start".error;
                 serverBooting = false;
             }).play(clock);

// debug statements, for reference


     doWhenBooted { arg onComplete, timeout = 20.0;
         var cancel, upd;

         if( serverRunning.not, {
             upd = UpdateListener.newFor( this, {
                 if( serverRunning.debug("swing updatelistener: is 
running"), {
                     cancel.stop;
"stopped cancel thread".debug;
                     upd.remove;
                     fork(onComplete);
                 });
             }, \serverRunning);
             cancel = {
                 timeout.wait;
"cancel thread awake".debug;
                 upd.remove;
                 if(serverRunning.not) {
                     "SwingOSC server failed to start".error;
                 };
                 serverBooting = false;
             }.fork( clock );
         }, { fork(onComplete) });
     }
