Update of bug #51903 (project octave):
Status: Confirmed => Patch Submitted
_______________________________________________________
Follow-up Comment #17:
The attached patch works for me. I'm not sure that it's the best
implementation, but it's a starting point. The idea is to block SIGTSTP in
all threads except the interpreter, and to also unblock it for any processes
we create. I didn't add SIGTSTP to the list of async signals in
signal-wrappers.c because then it would be unblocked in the thread that
watches signals and only delivered with a delay (set a global variable, check
it when octave_quit() is called). The nice thing about this method is that we
don't have to install our own signal handler for SIGTSTP that might interfere
with the one readline installs.
(file #45304)
