Hello,
I think that there is a small problem in ooRexx 4.0 trunk:
common/platform/unix/SysThread.cpp
...
// create a new thread and attach to an activity
void SysThread::createThread(void)
{
pthread_attr_t newThreadAttr;
int schedpolicy, maxpri, minpri;
struct sched_param schedparam;
// Create an attr block for Thread.
pthread_attr_init(&newThreadAttr);
#if defined(LINUX) || defined(OPSYS_SUN) || defined(AIX)
/* scheduling on two threads controlled by the result method of the */
/* message object do not work properly without an enhanced priority */
pthread_getschedparam(pthread_self(), &schedpolicy, &schedparam);
#ifdef _POSIX_PRIORITY_SCHEDULING
maxpri = sched_get_priority_max(schedpolicy);
minpri = sched_get_priority_min(schedpolicy);
#endif
schedparam.sched_priority = (minpri + maxpri) / 2;
...
If _POSIX_PRIORITY_SCHEDULING is not defined then minpri / maxpri is
undefined.
Should we move the "schedparam.sched_priority = (minpri + maxpri) / 2;"
in the
#ifdef _POSIX_PRIORITY_SCHEDULING or should we use a default value for
schedparam.sched_priority if _POSIX_PRIORITY_SCHEDULING is not defined.
If we move it then the original values would be used in case
_POSIX_PRIORITY_SCHEDULING is not defined....
Bye
Rainer
