If we want to re-instate the old system it is a matter of a few lines.
But that would be a step back IMHO. And writing a full template based
notification system could not be done in two hours by one. It's not a
huge task, but definitely more than two hours :-)
Besides, I really think we should sto
Let me add a comment here on why we can't just emit a signal to
everyone...
In the future it is not impossible that many apps are connected to
Zeitgeist. Indeed if we have a hook in Gtk+ or Glib then *all* apps are
connected to us. Thus we'd send a signal to all desktop processes -
waking them up
I think I read somewhere in the Tracker changelogs that they committed a
fix for this, but maybe I mistook a normal comment on the matter as a
real committed fix...
Regarding 0.3 status I think we should ship 0.3.0 without it. There's
nothing stopping us having 0.3.1 next week already of we have g
I am looking into the directed signals approach, and from a look at the
DBus spec this should be possible. If we can somehow create our own
dbus.lowlevel.SignalMessage then we can call
set_destination(unique_name) on that. See
http://dbus.freedesktop.org/doc/dbus-python/api/. Alse see
http://dbus.f
Ok. I think I know how to do this now. I just need to find the time to
actually write the code :-)
Look at the nested emit_signal() method here:

In the attached branch I tried to put together a sample dbus service
which *should* send directed signals, but somehow it is not working as I
expect it to work.
There are two scripts, service.py which starts the service, and
client.py (0|1), the client. starting the client with argument '1' means
maybe this screencasts help to understand whyt I mean ;)

Cool that you did this test Markus! I am a bit troubled by the results
though...
I fear that signals are by definition always broadcasted. We may be able
to work around this by setting a match rule on each signal connection on
the client side, but I am not sure... Something like adding a named

just my piece of non techi view to this issue
we should make sure that it gets in with the 0.3.1 release since teamgeist also
depends on it.

Yeah, I agree you way is the way to go (I'm just wondering why the
Tracker guys didn't think of this, as I had a talk with Ivan at
Bolzano and he told me they also have problems with signals and that
their not optimal solution was to send a different signal for every
type of data).
