Operating Systems Solaris Solaris 8 -> Solaris 10 = problem :/ Post 302508747 by Tinkh on Tuesday 29th of March 2011 02:33:57 AM

They start on the same OS (solaris 8 when it works, solaris 10 when it does'nt work).

Thread 1 (very simplification of source code) :
Code:
 
main_function {  /*(called every 20ms)*/
 
   (... some functions ...)
 
   pthread_mutex_lock(&mutexA);
   Read_data1;
   Read_data2;
   if (Status1)     {
      Status1=0;
      pthread_cond_wait(&synchroA,&mutexA);
   }
   else {
      pthread_cond_signal(&synchroB);
      Status2=1;
   }
   pthread_mutex_unlock(&mutexA);
 
   (... some functions ...)
 
   pthread_mutex_lock(&mutexA);
   Write_data3;
   Write_data4;
   if (Status2)     {
      Status2=0;
      pthread_cond_wait(&synchroA,&mutexA);
   }
   else {
      pthread_cond_signal(&synchroB);
      Status2=1;
   }
   pthread_mutex_unlock(&mutexA);
 
   Read_data5
}

Thread 2 is the same code with mutexB instead of mutexA, and synchroB instead of synchroA.

On Solaris 8 : no problem.
On Solaris 10 : On the first pthread_cond_wait (in thread 1 per example), program never returns to thread2 for mystery reasons.
