Add g_main_context_ref_thread_default(), which always returns a reffed GMainContext, rather than sometimes returning a (non-reffed) GMainContext, and sometimes returning NULL. This simplifies the bookkeeping in any code that needs to keep a reference to the thread-default context for a while. https://bugzilla.gnome.org/show_bug.cgi?id=660994

|
*
|

|
* handling the call (e.g. return an error via
|
|
* g_dbus_method_invocation_return_error()).
|
|
*
|
|
* Otherwise, if %TRUE is returned, signal emission continues. If no
|
|
* handlers return %FALSE, then the method is dispatched. If
|
|
* @interface has an enclosing #GDBusObjectSkeleton, then the
|
|
* #GDBusObjectSkeleton::authorize-method signal handlers run before
|
|
* the handlers for this signal.
|
|
*
|
|
* The default class handler just returns %TRUE.
|
|
*
|
|
* Please note that the common case is optimized: if no signals

* handlers are connected and the default class handler isn't
|
|
* overridden (for both @interface and the enclosing
|
|
* #GDBusObjectSkeleton, if any) and #GDBusInterfaceSkeleton:g-flags does

|
* not have the
|
|
* %G_DBUS_INTERFACE_SKELETON_FLAGS_HANDLE_METHOD_INVOCATIONS_IN_THREAD
|
|
* flags set, no dedicated thread is ever used and the call will be
|
|
* handled in the same thread as the object that @interface belongs
|
|
* to was exported in.
|
|
*
|
|
* Returns: %TRUE if the call is authorized, %FALSE otherwise.
