Create a new Interface class which is the parent class of + Object, and make the ObjectType metaclass into InterfaceType. + + 2. Patch written with Rob Taylor to replace use of method_vtable + with code that walks the class's __MRO__ (method resolution order) + to behave like Python does when invoking methods and allow + overriding as you'd expect. Code is quite tricky because + we have to find two methods, the one to invoke which has the + right name and isn't decorated with the /wrong/ interface, + and the one to pick up the signatures from which is decorated + with the right interface. + + The same caveats apply as to normal multiple inheritance - + this has undefined behaviour if you try and inherit from two + classes that define a method with the same name but are + decorated with different interfaces. You should decorate + your overriding method with the interface you want. + + 3. Replace grungy introspection XML generation code in the metaclass + with dictionaries that cope correctly with multiple inheritance + and the overriding of methods. This also uses the signature + decorations to provide correct introspection data, including + the debut appearance of the types of your return values. :D + + * test/python/test-client.py, test/python/test-service.py: Add a test + case to try invoking an method that overrides one inherited from a + D-Bus interface class. + +2005-10-29 Robert McQueen <robot101@debian.org> + * python/dbus_bindings.pyx: Tweak 'raise AssertionError' to assert(). Add checking for the end of struct character when marshalling a struct in MessageIter.append_strict. |
