Subject: 24.2; C-c C-c in shell mode on OSX sends SIGINT
Date: Tue, 18 Dec 2012 22:35:14 -0800

If you ssh someplace in shell mode and hit C-c C-c, it kills the ssh
process.  It wasn't always that way.  The intended effect is just to
kill the foreground process on the remote host, as if you'd hit C-c
at a terminal.

It looks like Darwin doesn't have SIGNALS_VIA_CHARACTERS defined.  Since
it's BSD-like I'd guess it really should.

Could someone with a Mac try this out with the emacs-24 branch, and see
if it fixes the issue and doesn't cause any obvious problems?
One way to do it is to run configure as normal, then edit src/config.h
and uncomment

#define SIGNALS_VIA_CHARACTERS 1

(Seems surprising this has not been reported before. AFAICS, S_VIA_C has
never been defined on Darwin, so this issue should be present in Emacs
23 as well. Would be good if someone could check that too.)

I had it in emacs 23 as well.  I'll do a build of the latest with that change RSN.

Thanks,
Tim

Hello.

The problem exists in 23.  Defining SIGNALS_VIA_CHARACTERS fixes the issue.

Thanks. Any opinion on whether this change should go into emacs-24 or
trunk? Since the issue is present in 23 as well, that suggests trunk.
But if it's a safe fix, might as well go in emacs-24.

It sounds like it can go into emacs-24.
