Python message objects are unpickleable

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Run the following
import pickle
from something_pb2 import AProtobufMessage

m = AProtobufMessage()
pickle.dump(m)

What is the expected output? What do you see instead?

The message is unpickleable.

Please use labels and text to provide additional information.

Pickle used by many python libraries for IPC, and not rewriting those libraries 
is a good thing. Also, supporting pickle is as simple as adding __getstate__ 
and __setstate__. The fork below accomplishes this goal:

This will be fixed in the next release, 2.5.0, which is in progress. The change 
was unfortunately made just after the 2.4.1 release was cut.
