+
+ * glib/dbus-gvalue.c (marshal_variant): call _dbus_gvalue_marshal
+ instead of marshal basic so we can handle recursive types in a variant
+
+ * test/glib/test-dbus-glib.c: Add test for marshaling recurive types
+ in variants
+
+ * test/glib/test-service-glib.c, test-service-glib.xml
+ (my_object_echo_variant [EchoVariant],
+ my_object_process_variant_of_array_of_ints123
+ [ProcessVariantOfArrayOfInts123]):
+ Add two test methods
+
+ * python/introspect_parser.py: New module for parsing introspect
+ data.
+
+ * python/dbus_bindings.pyx:
+ (various places): when throwing errors fix to use errormsg instead
+ of message local variable because Pyrex can get confused with other
+ message variables (initial patch by Robert McQueen
+ <robert.mcqueen at collabora.co.uk>)
+ (MessageIter::parse_signature_block): new method for getting the next
+ block in a signiture.
+ (MessageIter::append_strict): new method for appending values strictly
+ using the passed in signature instead of guessing at the type
+ (MessageItter:: append_dict, append_struct, append_array): use
+ signatures to marshal children if the signature is available
+
+ * python/exceptions.py (IntrospectionParserException): new exception
+
+ * python/proxies.py (ProxyMethod::__call__): Marshal args with
+ introspected signatures if available, else we fall back to the
+ old way of doing things.
+ (ProxyObject::_introspect_reply_handler ): parse introspection data
+
+ * python/service.py (ObjectType::_reflect_on_method): Properly
+ terminate <method> if there are no args in the reflection data
+
+ * test/python/test-client.py: add tests for talking with the GLib
+ test server. This gives us better coverage for introspection since
+ python to python will always generate arguments as variants. It also
+ allows us to test the robustness of the GLib bindings and interlanguage
+ communications.
+
+
