#512 closed defect (fixed)

Bug in select ioqueue causing unnecessary sleep() to be invoked (thanks Sergey Bakulin)

Description (last modified by bennylp)

The pjsip endpoint will invoke pj_thread_sleep() if pj_ioqueue_poll() returns error:

  c = pj_ioqueue_poll( endpt->ioqueue, &timeout);
  if (c < 0) {

Unfortunately, the select ioqueue may incorrectly return error when select actually returns timeout:

 count = pj_sock_select(ioqueue->nfds+1, &rfdset, &wfdset, &xfdset, timeout);
 if (count <= 0)
   return -pj_get_netos_error();

Because of this, application may sleep for longer than what's required.

Please see for the details.
