exit_on_disconnect

[Cem Eliguzel]

Thanks Thiago.


What I don't understand is why there does not exist  a propagation mechanism
from dbus to applications via function
callbacks in order to handle disconnection mechanism.


Also, I strive to understand why the connection is broken. It's not because
of the fact that dbus-daemon died.
The dbus-daemon and thus the session is still alive. The application can
reconnect the dbus session next time
it is launched.


And, I can't see anything wrong with the dbus communictaion. Here is the
last few messages printed by dbus-monitor:


signal sender=:1.2 -> dest=(null destination) serial=1717
path=/org/gnome/Rygel1; interface=org.gnome.Rygel1; member=PlayerPlaying
   string "Bob Acri"
   string "Sleep Away"

signal sender=:1.2 -> dest=(null destination) serial=1718
path=/org/gnome/Rygel1; interface=org.gnome.Rygel1; member=PlayerStopped

signal sender=org.freedesktop.DBus -> dest=(null destination) serial=7
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus;
member=NameOwnerChanged
   string "org.gnome.Rygel1"
   string ":1.2"
   string ""
signal sender=org.freedesktop.DBus -> dest=(null destination) serial=8
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus;
member=NameOwnerChanged
   string ":1.2"
   string ":1.2"
   string ""


Do you see anything wrong here?


Kind regards,
Cem Eliguzel
