Re: DBusService and handling Disconnected signal

["Cem Eliguzel" <celiguzel ubicom com>]

Hi Zeeshan,

In our stress tests, we see that rygel quits suddenly after a few hours.  
When I investigated the problem I saw that this happens just after dbus  
connection is broken. Later, I discovered that the default action in dbus  
library on disconnect is to call _exit system call, which forces rygel to  
quit.


BTW, the default action is set to "exit" when the connection is created  
via dbus_bus_get method, which is the case in dbus-glib and thus in rygel.


There is that dbus_connection_set_exit_on_disconnect function in dbus  
library to disable the default "exit" action. On the other hand, there is  
no corresponding dbus-glib function that we can call from Rygel/vala codes.


When I asked a similar question to the dbus mail list in order to  
understand why dbus's default action is to exit on disconnect, it was said  
that applications using dbus usually depended on dbus session and if  
session somehow ended, application must exit.


What I would like to do is
	1. to handle disconnection event and reestablish the connection without  
forcing rygel to exit.
	2. to understand why dbus connection gets broken


Any idea, recommendation is appreciated.


Thanks in advance.


Regards,
Cem Eliguzel
