[packagekit] PolicyKit dbus interfacing

[Martin Pitt]

Hi Aidan,

Two potential traps here:

 * Are you sure that self.bus points to the session bus? If it's the
   same than used for packagekit itself, it's wrong, since PackageKit
   uses the system bus. Try s/self.bus/dbus.SessionBus().

 * I haven't seen that AuthorizationManager.SingleInstance object in
   recent PolicyKit versions at least. Starting with 0.7, the object
   name is "org.freedesktop.PolicyKit.AuthenticationAgent". If you are
   still using a very old PolicyKit version, that might be different,
   of course.

I am using this code in jockey without any problems with polkit >= 0.7:

       pk_auth = dbus.Interface(dbus.SessionBus().get_object(
           'org.freedesktop.PolicyKit.AuthenticationAgent', '/', False),
           'org.freedesktop.PolicyKit.AuthenticationAgent')
       # TODO: provide xid
       res = pk_auth.ObtainAuthorization(privilege_name, dbus.UInt32(0),
           dbus.UInt32(os.getpid()), timeout=300)

>         if(policykit == None):
>            print("Error: Could not get PolicyKit D-Bus Interface\n")
>         granted =
> policykit.ObtainAuthorization("org.freedesktop.packagekit.update-system", (dbus.UInt32)(tid), (dbus.UInt32)(os.getpid()))

What is tid here? The method expects a window XID here, not a
packagekit transaction ID.

HTH,

Martin
