A protobuf message will be corrupted in the following scenario:
1. Use LITE_RUNTIME.
2. Have an optional enum field following some other field.
3. Update protocol by adding new values to the enum.
4. Have an old client parse and serialize a message having enum field
set to a value the client does not understand.
5. Field preceeding the enum is now corrupted.
The bug is due to the fact that optimized fallthrough in parser code
does not update variablle 'tag' when jumping to the parser code for the
next field.

Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
https://developers.google.com/protocol-buffers/
Overview
Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can find protobuf's documentation on the Google Developers site.
This README file contains protobuf installation instructions. To install protobuf, you need to install the protocol compiler (used to compile .proto files) and the protobuf runtime for your chosen programming language.
Protocol Compiler Installation
The protocol compiler is written in C++. If you are using C++, please follow the C++ Installation Instructions to install protoc along with the C++ runtime.
For non-C++ users, the simplest way to install the protocol compiler is to download a pre-built binary from our release page:
https://github.com/google/protobuf/releases
In the downloads section of each release, you can find pre-built binaries in zip packages: protoc-$VERSION-$PLATFORM.zip. It contains the protoc binary as well as a set of standard .proto files distributed along with protobuf.
If you are looking for an old version that is not available in the release page, check out the maven repo here:
http://repo1.maven.org/maven2/com/google/protobuf/protoc/
These pre-built binaries are only provided for released versions. If you want to use the github master version at HEAD, or you need to modify protobuf code, or you are using C++, it's recommended to build your own protoc binary from source.
If you would like to build protoc binary from source, see the C++ Installation Instructions.
Protobuf Runtime Installation
Protobuf supports several different programming languages. For each programming language, you can find instructions in the corresponding source directory about how to install protobuf runtime for that specific language:
| Language | Source |
|---|---|
| C++ (include C++ runtime and protoc) | src |
| Java | java |
| Python | python |
| Objective-C | objectivec |
| C# | csharp |
| JavaNano | javanano |
| JavaScript | js |
| Ruby | ruby |
| Go | golang/protobuf |
| PHP | TBD |
Usage
