I've tried changing the default of the field to -1. Without rebuilding the Messages, re-reading them with the new definitions simply gives me the following: has_uploadlimit = false; uploadlimit= -1.
Since this is the case, I assume that the field in the Message itself isn't initialized, and that the problem isn't in the C++ porting, but rather in the way protobuf-net serializes the data (I'm using a C# application to do that). When the field isn't initialized, the has_ method in c++ returns false, but the Python implementation provides the default value, and so does the C# implementation. Does that sound like a realistic explanation?
