[Octave-bug-tracker] [bug #37672] GUI doesn't react to CTRL+C

[John W. Eaton]

Follow-up Comment #51, bug #37672 (project octave):

I'm attaching a change that allows system() to be interrupted when running
Octave with the GUI on Unixy systems.  However, I don't think we can use this
change because it will make Octave crash when interrupting calls to
multi-threaded BLAS functions, for example.

The only other thing I can think of is to somehow get (or track) the list of
processes that are in the same process group as Octave and send SIGINT to all
of them except the Octave process and then use pthread_kill to send SIGINT to
the Octave interpreter thread.  Is there some easy way to get the list of
processes in the process group?  If not, then it will take some work to keep
track of the processes that we create, and it won't be possible to track all
of the processes that might be created in .oct files (for example).
