Hi,
I'm planning to implement an alternative for dbusbindings.c [1]. The
major difference is the use of libgio instead of libdbus.
The reason is, that Emacs is already linked with libgio, when gconf or
gsettings is enabled (pretty much the default under GNU/Linux). libgio
opens an own connection to the D-Bus session bus in parallel to the
connection managed by libdbus. This runs into problems, if you need
information about the connection managed by libgio, as it is the case
for at-spi2 [2].
The implementation shall be backwards compatible, no Lisp interface
change shall be visible. During configuration time, it will be checked
whether libgio is available; if not libdbus will be used.
Comments?
[1] The alternative could be either a new gdbusbindings.c file, or
something controlled by configure flags inside dbusbindings.c. I haven't
checked yet, what is more appropriate.
[2] See also <http://thread.gmane.org/gmane.comp.freedesktop.dbus/14880>
Best regards, Michael.

Please ensure that libgio isn't used unless the toolkit is gtk.
An athena build shouldn't have dependencies on glib.

Should be possible.

All my Athena builds link to glib since 23.1. I couldn't care less.
At least rsvg and ImageMagick support bring it in (Debian testing).

So does GSettings.

Sure. And also GConf.
But it shouldn't hurt, to enable libgio for GDBus only if HAVE_GTK is "yes".
At least for the time being.
When Emacs supports threading, it might be a good idea to use libgio
anyway for D-Bus if installed, because libdbus is said to have problems
with threads.

I don't see a particular problem in requiring glib to be able to build
with D-Bus support. The situation where someone would want to build an
Emacs that supports D-Bus but with a configuration which doesn't use
glib seems rather unlikely.

I did understand James, that he doesn't need D-Bus, and he doesn't want
a glib dependency in his athena-based build because of D-Bus.
"with-dbus" is the default configure option in Emacs.

If he doesn't want glib, then he'll have to explicitly disable dbus,
which I think is an acceptable price to pay.
