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 address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

This is a feature request to add the facility to start an emacs server
using a command-line option that runs as a foreground process instead
of forking a daemon and exiting.


Forking a daemon then exiting the main process is incompatible with
systems that manage processes as services, such as launchd on OS X,
therefore it is not possible to create an effective launchd service
using emacs in daemon mode.

Possible Solution:

For review I have included a patch that adds a --server command line
option that does what the --daemon option does, except it runs the
server in the foreground process rather than forking a daemon and

Please note that I am new to emacs and nix based operating systems and
in the short time I have had to spend on this was unable to add a SIGINT
handler to gracefully shutdown the emacs server, not that it matters
to launchd since it should send SIGTERM, but a solution would be nice.

There appear to be issues on OS X with creating a new frame using the -c option
to emacsclient as emacs crashes (so far during garbage collection) when
doing this, however I am still learning the dev tools available to me on this
platform and it will be a while before I could effectively report such bugs, so
this is just an FYI. 

As I'm using a debug build so I can investigate further, can you confirm
that the build configure options I've used are ok and not likely to be
contributing to the instability, are there any other options I should be

Please also note that this is the first time I have engaged with an open
source project so if I'm not doing it right let me know.

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'.
