Integrate recent changes from google3.
protoc
- New flags --encode and --decode can be used to convert between protobuf text
format and binary format from the command-line.
- New flag --descriptor_set_out can be used to write FileDescriptorProtos for
all parsed files directly into a single output file. This is particularly
useful if you wish to parse .proto files from programs written in languages
other than C++: just run protoc as a background process and have it output
a FileDescriptorList, then parse that natively.
C++
- Reflection objects are now per-class rather than per-instance. To make this
possible, the Reflection interface had to be changed such that all methods
take the Message instance as a parameter. This change improves performance
significantly in memory-bandwidth-limited use cases, since it makes the
message objects smaller. Note that source-incompatible interface changes
like this will not be made again after the library leaves beta.
Python
- MergeFrom(message) and CopyFrom(message) are now implemented.
- SerializeToString() raises an exception if the message is missing required
fields.
- Code organization improvements.
- Fixed doc comments for RpcController and RpcChannel, which had somehow been
swapped.
