GBus discussion

[Fan Wu]

Hi,

I can only speak for myself here. The reason I'm looking at gbus is
mainly for the support of proxy and name/signal/owner tracker. Since
I'm going to use threads, I don't feel less convenient without the
glib mainloop.

If that is the case you can go further by getting rid of all the
register/unregister calls, and ask user to fill in a big table which
has all the callback/type/path/name information, and then pass the
table to a dbus_start() which will set up the loop and get the
connection and call the callbacks if needed.

Why would you need multiple NameOwner objects for one name?

The difference between NameLost and FailedToAcquire is, for NameLost
most likely something needs to be cleaned up before exit; while for
FailedToAcquire, probably nothing has been started yet so the clean up
can be saved. I would say some application might appreciate the extra
information, if just for logging purpose.

Thanks,
