Subject: Starting emacs as a daemon, and requesting a client with -n
Date: Thu, 1 Nov 2012 17:10:42 -0400

[Message part 1 (text/plain, inline)]

For the past month or so, when compiling from the latest source, I have
been having an issue starting Emacs as a daemon (emacs --daemon) and
requesting a client with "emacsclient -c -n". If I include the "-n"
option, nothing appears to happen, though, if I request a client with
just "-c", a new frame does appear.

Thanks for the report. It works fine for me on GNU/Linux, configured
--without-dbus to match your configuration. Does it happen for you with
emacs -Q --daemon? Maybe it is Mac specific.

Can anyone else with a Mac reproduce this?

Yes.  Basically server.el does not handle the non-display situation of Nextstep.  When emacsclient connects it sends back window system unsupported, and then emacsclient tries to create a tty frame (which end up being a GUI frame).  A side effect is that emacsclient gives two "Waiting for Emacs..." messages.

But with -n, there is just window system unsupported, no attempt to create a tty frame.

The patch below fixes this, but the code is probably in the wrong place.

If it works, I'd suggest installing it in emacs-24 and maybe looking for
a better fix in trunk.

Ok, slightly different solution checked in.
