Package: nethack
Version: 3.2.2-16
Pressing ^Z in xnethack, when it's being run from the window manager's
menu, can cause the window manager to stop. Which is rather difficult
to fix if you don't know what you're going. (If I were less
knowledgable, I'd probably have thought that the system had hung.) A
SIGTSTP causes the entire process group to suspend, not just the
foremost process (this is presumably so that you can suspend,
e.g. your editor *and* mailer, or the like.)
Actually, there's little or no reason to even support ^Z in xnethack.
It makes sense for the terminal version, but not for the X version.
Something more along the lines of what emacs does (suspends in a
terminal, iconizes in X) would make more sense.
The worst part is that ^Z is right next to ^A, which is a very useful
command in nethack, so this is really not difficult to do by
accident. (I'm only surprised I didn't discover this years ago.)
I've looked over the code just a little, and I can say that the
problem is basically in sys/share/ioctl.c, the last function,
dosuspend(), which *unconditionally* sends SIGTSTP. Unfortunately, I
don't have a quick patch as yet, but I might be able to come up with
one if pressed. But I thought you might have some contact with the NH
dev team, who are probably more qualified than I to provide a
reasonable, portable solution.

Hi,
it seems that upstream has changed something, at least when I press ^Z, I
get "suspend not available."
Closing therefore, please reopen if I failed to reproduce appropiatly.
