-Subject: lib: Add proper error and cancellable handling to UpClient
- constructor
-
-A GObject's _init() should never fail or block, but this is currently the case
-as up_client_init() connects to upowerd on D-Bus. Convert this to the GInitable
-interface and provide a new constructor up_client_new_full() which accepts a
-GCancellable and GError, so that clients can do proper error handling
-and reporting.
-
-This changes up_client_new() to return NULL when connecting to upowerd fails.
-This provides a more well-defined behaviour in this case as clients can check
-for this and our methods stop segfaulting as they have checks like
-
- g_return_val_if_fail (UP_IS_CLIENT (client), ...)
-
-Previously we returned a valid object, but trying to call any method on it
-segfaulted due to the NULL D-Bus proxy, so client code had no chance to check
-whether the UpClient object was really valid.
