GConf+DBus in jhbuild

[Murray Cumming]

Apparently GConf has switcged to using D-Bus, which explains why I'm
getting errors from applications running in "jhbuild shell".

Is there a simple way to make my jhbuild environment use the D-Bus and
associated service files from my jhbuild-built /opt/gnome prefix? I
imagine that it would be difficult given that old versions of D-Bus (and
GConf) are already running from the regular prefix.

If there's an easy way, we should add it to the sample jhbuild .rc file.

Does your dbus session.conf have

 <standard_session_servicedirs />

in it?  If so, then it should look in $XDG_DATA_DIRS/dbus-1/services.
XDG_DATA_DIRS should already be set up to include /opt/gnome/share

Basically, I'm confused why this isn't working for you out of the box.

Yes, I have that in both
  /etc/dbus-1/session.conf
and
  /opt/gnome220/etc/dbus-1/session.conf
(actually a gnome2.23 build)

Yes, it seems to be correct in jhbuild:

murrayc@murrayc-desktop:~$ echo $XDG_DATA_DIRS
/usr/local/share/:/usr/share/:/usr/share/gdm/

murrayc@murrayc-desktop:~$ jhbuild shell
murrayc@murrayc-desktop:~$ echo $XDG_DATA_DIRS
/opt/gnome220/share:/usr/local/share/:/usr/share/:/usr/share/gdm/

Just so I understand, you are

1) logging in with a gnome 2.22 desktop
2) typing jhbuild shell
3) trying to run gnome 2.24 programs from the shell and getting errors

Is that correct?  What error messages are you getting?

Yes. In Ubuntu Hardy.

Yes.

Yes.

For instance, gedit says:

"
An error occurred while loading or saving configuration information for
Text Editor. Some of your configuration settings may not work properly.
"

Pressing the Details button gives me this repeated several times:

"
Failed to contact configuration server; some possible causes are that
you need to enable TCP/IP networking for ORBit, or you have stale NFS
locks due to a system crash. See http://www.gnome.org/projects/gconf/
for information. (Details -  1: Could not send message to gconf daemon:
The name org.gnome.GConf was not provided by any .service files)
"

I now have this on my laptop as well as my desktop PC so I really think
it must be a common problem. My .jhbuildrc (attached) is very standard,
I believe.

ps shows that the jhbuild gconfd-2 is running :

murrayc@murrayc-x61:~$ ps -ef | grep "gconfd"
murrayc   5755     1  0 08:36 ?
00:00:00 /usr/lib/libgconf2-4/gconfd-2 4
murrayc   6962  6482  0 08:43 pts/0    00:00:00 grep gconfd

I don't know if jhbuild shell ensures a fresh dbus session bus gets
started or not.

If not, that could cause your problem.

What if you do,

jhbuild shell
dbus-launch --exit-with-session bash

and then type your commands?

Yes, that fixes it. Thanks for the useful workaround.

I wonder what would be the appropriate way to fix this properly in
jhbuild. Presumably the regular non-jhbuild stuff needs to use its
regular D-Bus (and regular GConf) processes, and jhbuild should use its
own, without the two being confused.

I'd say jhbuild shell should probably just do the dbus-launch itself,
and jhbuild run (that's what's used to launch an entire session right?
or am I misremembering?) should rely on the distribution to start a
session bus.
