Subject: 24.3; emacsclient -c behavior regression
Date: Tue, 30 Apr 2013 17:48:30 +0200

I think this is a regression in emacs24 (lucid), because this used to 
work under emacs23:

If you start emacs --daemon

and you have the following:

(add-hook 'after-make-frame-functions
  (lambda (frame)
    (print (display-graphic-p))))

and you create a new frame via:

emacsclient -c

you will notice that the result is always 'f'.
Not only that, but any frame manipulation will cause the daemon to crash.

emacsclient -e '(make-frame)'

does the same(!).
Yet, if you create a new frame from *that* newly created frame via M-x 
(make-frame), the second new frame is indeed graphic.

This gave me all sorts of headache with the color-theme package actually 
crashing emacs, only in daemon mode, and only when creating a new frame 
via emacsclient.

If you set a hook in server-visit-hook though, the (selected-frame) is 
graphic. What's happening?

I'm using emacs24-lucid from debian.

(This bug report unfortunately got no response at the time.)

The result is always nil, yes -- but if you use the frame as a parameter
to that function, you get the correct results:

(setq after-make-frame-functions
      (list
       (lambda (frame)
	 (message "frame: %s %s" frame (display-graphic-p frame)))))

./lib-src/emacsclient -c

frame: #<frame GNU Emacs at xo 0x5574a438f338> t

> Not only that, but any frame manipulation will cause the daemon to crash.
>
> emacsclient -e '(make-frame)'

This seems to be fixed, though.  It now just reports an error:

*ERROR*: Unknown terminal type

So I think everything here works as designed, and I'm closing this bug
report.  If there's more to be done here, please respond to the debbugs
address and we'll reopen.
