- Audit @todo and FIXME for security issues
- - The convenience functions in dbus-bus.h should perhaps have
- the signatures that they would have if they were autogenerated
- stubs. e.g. the acquire service function. We should also evaluate
- which of these functions to include, in light of the fact that
- GLib/Qt native stubs will probably also exist.
-
- the "break loader" and valid/invalid message tests are all disabled;
they need to be fixed and re-enabled with the new message args stuff.
I think I want to drop the .message files thing and just have code
Might as Well for 1.0
===
- - add dbus_message_has_path(), maybe has_member/interface
-
- protocol version in each message is pretty silly
Can Be Post 1.0
