2005-10-24 Robert McQueen <robot101@debian.org> * python/dbus_bindings.pyx (String, MessageIter): make D-Bus strings derive from unicode instead of str, and encode/decode UTF-8 when marshalling/unmarshalling bus messages * python/introspect_parser.py: encode introspection data as UTF-8 before passing the buffer into libxml2 * test/python/test-client.py: add unicode test strings * test/data/valid-service-files/.cvsignore, test/python/.cvsignore: ignore generated python test files

2005-11-07 Robert McQueen <robot101@debian.org> * python/decorators.py: Change emit_signal function to use the signature annotation of the signal when marhsalling the arguments from the service. Fix a bug where the code checking signature length against argument length referenced the wrong variable. * python/introspect_parser.py: Avoid adding the type signature of signal arguments to any methods which occur after them in the introspection data (!) by making the parser a little more careful about its current state. * python/service.py: Remove debug prints from last commit (again :D). * test/python/test-client.py, test/python/test-service.py: Add test signals with signature decorators to test the strict marshalling code gives errors at the right time. Could do with checking the signals actually get emitted too, given that the test does nothing with signals at the moment...
