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-pr...@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.

Thanks. I checked in a fix, can you please try again?

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.

Bye,
Tassilo

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
