[Dextrose] [sugar PATCH v2] sl#3326: Do not allow two telepathy-coonection objects to be instantiated, for a single Telepathy-Gabble-Account.

[Ajay Garg]

Thanks to Jerry Vonau, for inspiring and guiding me to solve this :-)

Thanks to Daniel Drake, for the review of version-1 patch.

===================================================================================


Changes of version-2 over version-1 :
=====================================

Version-1 attached callback signals to only one of the two telepathy-connection-objects,
instantiated per telepathy-gabble-account. However, two telepathy-connection-objects 
were instantiated nevertheless. So, we needed to ensure that only one telepathy-connection-object
per telepathy-gabble-account be created (Thanks Daniel again).



Note that ::

a)
In the method "def __account_property_changed_cb(self, properties)", the properties were
investigated in each hit of this function. Unfortunately, in each call, 
 
                 properties['ConnectionStatus'] = 1
                               or
                 properties['ConnectionStatus'] = 2

which correspond to "Connecting" and "Disconnected" states, respectively.



At no time, was the value

                 properties['ConnectionStatus'] = 0

which would have corresponded to "Connected" state.


Please see ::  http://telepathy.freedesktop.org/spec/Connection.html#Enum:Connection_Status





b)
For every hit of the function "def __account_property_changed_cb(self, properties)", the value of

                properties['Connection'] 

was either "/", or one other connection-string, WHICH REMAINED CONSTANT IN EVERY CALL (i.e. whenever
the value was not "/").





c)
So, simply ensuring that there would be just one telepathy-connection-object per telepathy-connection-path
(the OTHER value besides "/" in step b)), we would be done.
