Follow-up Comment #11, bug #44485 (project octave):
Good question. That error looks like it is coming from the Octave core,
right? I assumed that quitting the application would gracefully stop the
Octave CLI thread. But apparently not. I'm going to think about this one for
a bit, and if you'd like to try something, let me know if it works. It should
be just one or two strategically placed signals or function calls.
The question I have is whether we might have to stop the CLI thread (actually
two threads that I see). The reason is that if we issue the current Qt signal
that causes and interrupt, i.e.,
connect (command_window, SIGNAL (interrupt_signal (void)),
_octave_qt_link, SLOT (terminal_interrupt (void)));
and
void
terminal_dock_widget::terminal_interrupt (void)
{
emit interrupt_signal ();
}
it's doesn't solve this issue (I think) because signals across threads are
queued, slots across threads aren't processed immediately, unlike in-thread
signals/slots. I think we'd have to simply stop the threads.
As I said, there are two threads, one for the octave CLI and one for the
command queue:
QApplication application (argc, argv);
octave_cli_thread main_thread (argc, argv);
application.setQuitOnLastWindowClosed (false);
main_thread.start ();
return application.exec ();
and
octave_qt_link::octave_qt_link (QWidget *p)
: octave_link (), main_thread (new QThread ()),
command_interpreter (new octave_interpreter ())
{
connect (this, SIGNAL (execute_interpreter_signal (void)),
command_interpreter, SLOT (execute (void)));
connect (command_interpreter, SIGNAL (octave_ready_signal ()),
p, SLOT (handle_octave_ready ()));
command_interpreter->moveToThread (main_thread);
main_thread->start ();
We need some way of accessing and stopping these threads directly, not with
slots. There need to be a couple extra pointers and short functions to do
that.
I'll think about for a day or so.
