[Octave-patch-tracker] [patch #8016] Prototype octave_value_list transfer

[Dan Sebald]

Follow-up Comment #1, patch #8016 (project octave):

Will try something like this at a later time:

octave_value_list result = eval_string(...,nout)
if (OK)
  for i=0; i< nout; i++
  {
    copy_count(i) = result(i).rep.count;
    result(i).rep.count = -1;
  }
  emit command_result (result)

  put_thread_to_sleep()

  //Restore the count
  for i=0; i< nout; i++
  {
    result(i).rep.count = copy_count(i);
  }

None of the copy/deletes going on in the signal/slot mechanism will have any
effect on the rep-count.  In the GUI thread would be:

octave-link::handle_command_result (QObject *ID, octave_value_list& result)
{
  // Transmit result to other objects in GUI.
  emit have_command_result (ID, result);

  // No longer need this data
  wake_up_the_worker_thread()
}
