[Sugar-devel] #2295 UNSP: Sugar 0.88 [Dextrose] not reporting all favourite connections to NetworkManager at startup

[Franco Miceli]

Tomeu,

Following code traces of ListConnections from the NMSettings class within
Network.py, I've come across the following sequence of calls from NM's code:

NetworkManager.c's main function calls nm-manager-get (from nm-manager.c).

Within nm-mannager-get the function initial_get_connections gets called. I
think it is this the function we are looking for since it invokes other
functions (query_connections and poke_system_settings_daemon_cb) that call
the ListConnections through the d-bus (dbus_gproxy_begin_call()).

So effectively I think that ListConnections is the one NM calls at startup.

Hope I helped.

Cheers
