dynamic loading of extensions

[Seif Lotfy]

When wanting to use a new extension one has to restart zeitgeist. Problem with that is that all monitors are then gone.
My suggestion would be to be able to dynamically load extension by monitoring the extensions directories and pulling in the new extension on runtime.

Apps should be able to handle this, Zeitgeist restarting is something
that can happen.

The fact that all monitors are gone when restarting zeitgeist is not an argument, because there is not guarantee that the zeitgeist daemon will run forever, so if you connect a monitor to the daemon, you have to handle the case of a daemon restart/shutdown, aka reconnecting the monitors after the restart.
I don't like the overall idea of watching extension folders for new extensions, because I consider the fact that a new extension is added a very rare one.

an extension added might be rare but lets say someone installs gnome-activity-journal via software-center. He will never be able to get it to work unless he restarts the session or zeitgeist. IMHO this is not inviting to users and especially non-techies. Either we restart Zeitgeist upon installation of new extension automatically or we load new extensions in dynamically.

Restarting of zeitgeist after installation the GAJ package requires no user action, because GAJ does the right thing (tm), in its package install process a SIGHUB signal is send to zeitgeist, which shuts the daemon down. - If this is not the case right now, it's a bug in the packaging of GAJ.

And to make one thing a bit clearer, there is not need to 'restart' the daemon, all we have to do is to *stop* the daemon, the daemon will then start again whenever needed.

ups, pressed 'post comment' to early, from my POV this bug is 'won't fix'

Dynamic loading is tricky with dbus services and all - i'm not sure it's such a good idea.

And fwiw - libzeitgeist detects when the daemon comes and goes and reinstates any monitors it has running - so restarting the daemon is not an issue for libzeitgeist customers

ok since we already have 3* -1 I am changing the bug to "won' fix"
