[omniORB] "multiplexed calls" in local case?

[tihomir.sokcevic@acterna.com]

Hello,

I wrote a little echo-like example to test the  "multiplexed calls" ability of
omniORB4.
I got this results:
  different machines -> everything works fine,
  different processes on one machine -> everything works fine,
  different threads in one process -> omniORB4 deadlocks!

Is this a bug or a feature (a question of speed)?

I'm using omniORB4-20011019.

The example's source fragments:

//IDL code
interface Echo {
  oneway void begin(in string mesg);
  oneway void doing(in string mesg);
  oneway void done(in string mesg);
};

//Client code
Echo_var echoref = Echo::_narrow(obj);
echoref->begin("1");
echoref->begin("2");
echoref->doing("1");
echoref->done("1");
echoref->doing("2");
echoref->done("2");


//Server code
omni_mutex mx;
int context= 0;

void Echo_i::begin(const char* mesg) {
 while(context) {}  //wait until free
 omni_mutex_lock lock(mx);
 context = (int) mesg[0];     //set current context
}

void Echo_i::doing(const char* mesg) {
 while(context!= (int) mesg[0]) {} //wait until current context is processed
}

void Echo_i::done(const char* mesg) {
 while(context!= (int) mesg[0]) {} //wait until current context is processed
 omni_mutex_lock lock(mx);
 context = 0;  //clear current context
}
