bug#1019: 23.0.60; emacs --daemon doesn't work on a console

[Tassilo Horn]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I'd like to start an emacs daemon on startup in a runlevel script.  So I
added

  su --login --command 'emacs --daemon' horn

but that doesn't start a daemon.  So I tried issuing

  emacs --daemon

or

  emacs -Q --daemon

on a login shell, but that returns instantly and doesn't start an emacs
daemon, too.  Running inside gdb only says "Program exited normally."

When issuing the same commands inside a X terminal emulator they work as
they should, though.

What's going wrong?

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.60/etc/DEBUG for instructions.

Yes, it works now.  Thanks a lot.

But I have two additional questions.

1) How do I shutdown the emacs server cleanly? 

  IMO there should be some --kill-daemon option so that it can really be
  integrated as a system service.  Then of course there's the question
  what to do if unsaved buffers and running processes exist, where I
  don't have a good answer now.  Maybe killing processes unconditionally
  and saving files as #<filerame>#.  Unsaved buffers could be saved as
  ~/.emacs.d/unsaved-buffers/<buffername>.

2) In my .emacs I have (if (fboundp 'tool-bar-mode) (tool-bar-mode -1)).
   But when I start emacsclient -c the first time, it has a toolbar,
   although the value of `tool-bar-mode' is nil.  Then I have to toggle
   t-b-m twice, and from there on it's disabled for the current and all
   new frames.  I disable the scroll- and menu-bars the same way, and
   they are disabled directly, e.g. even for the first X frame.

Use emacsclient to eval `save-buffers-kill-emacs'?

  > 2) In my .emacs I have (if (fboundp 'tool-bar-mode) (tool-bar-mode -1)).

There's a better way to do this, use ~/.Xdefaults:

Emacs.ToolBar:                  0
Emacs.verticalScrollBars:       off

I checked in a fix to fix the initialization of tool-bar-mode and menu-bar-mode.

I'm pretty sure I tried `kill-emacs' yesterday and the emacs process
survived, but the server was shut down, so I couldn't connect anymore.
But I tested again and it works.  Thanks for the hint.

Yes, I know.  But I like to have all my emacs customizations in lisp and
in ~/.emacs.

Nothing visible has changed for me.  Still the first X11 frame after
starting the daemon has a tool-bar (and tool-bar-mode is nil).

Did you recompile startup.el and dump emacs again?

I used my package manager (paludis).  It always copies the fresh source
tree to some location and makes a full bootstrap.

It works for me with a .emacs containing just your code:
 (if (fboundp 'tool-bar-mode) (tool-bar-mode -1))

Yes, I updated my sources 30 minutes ago and made a complete bootstrap
to be sure.  Still, emacsclient -c gives a frame with toolbar and
tool-bar-mode set to nil.  `C-x 5 0' and another emacsclient -c again
gives another frame with toolbar.  So I really have to toggle t-b-m
twice and from then on it's all fine for this and all next frames.

When did you check it out?  I checked in a fix a few hours ago that
should have fixed this problem.

Your fix works for me.  There's no tool-bar on the initial frame.

I will have to test it again but if it can help, here is the
output from C-u M-x emacs-version:

This issue seem to have been fixed by:

2008-10-04  Dan Nicolaescu  <dann@ics.uci.edu>

      * faces.el (x-create-frame-with-faces): Only setup the toolbar if
      tool-bar-mode is on.

but I had to back out that change later because it was causing problems
in compile.el.  The compile.el problems are independent of this change,
and are described in bug#1133.
