[Octave-bug-tracker] [bug #38305] file dialog causes crash

[Dan Sebald]

Follow-up Comment #21, bug #38305 (project octave):

There are a couple ways.  In Gnome (what I'm using) there is a system monitor
feature under the menu "System Tools".  I would imagine KDE has something
similar.  The system monitor shows several things like CPU usage, network
usage, system memory.  There is another category called Processes which lists
stats and tracks processes.

Or, one could use the OS command "ps -u <account name>" and that will list the
same information that is shown in the Processes tab of the system monitor. 
For example, on my system


[sebald@ ~]$ ps -u sebald
  PID TTY          TIME CMD
 1670 ?        00:00:00 gnome-keyring-d
 1678 ?        00:00:00 gnome-session
[SNIP]
 2490 pts/1    00:00:00 bash
 2506 pts/2    00:00:00 bash
 2519 pts/2    00:00:00 lt-octave
 2652 ?        00:01:37 lt-octave
 2918 ?        00:00:57 xmms
 3380 ?        00:00:00 gvim
 3742 pts/4    00:00:00 bash
 3777 pts/4    00:00:00 ps


Notice how "ps" is the last process...that's the process associated with the
command just run.

We know there should be at least two processes associated with Octave run in
the GUI.  The main application GUI is a process and then the Octave core (or
"worker process") is launched as a separate QProcess inside the GUI.  (If you
see some discussion on the list from time to time about "thread safe" and so
on, that's because we now have two separate processes interacting with one
another.)
