Alex Eagle d2b71b347d feat: automate publishing releases to Bazel Central Registry (#16014)
Note, recent releases on the BCR have a patch set applied, and it seems these patches are developed independently to "fix" each protobuf release, rather than make changes to protobuf repo.

The effect of this PR will be to create a *broken* publish to BCR for each protobuf release. At least this red PR on BCR will be our indication that the patches need to be manually replayed there.

In parallel, starting with #16013 I'll apply as many of those patches to the protobuf repo as possible. That will reduce the manual effort for each release.

Replaces https://github.com/protocolbuffers/protobuf/pull/14565 which originated from my fork so the tests wouldn't run.

Closes #16014

README.md

Protocol Buffers - Google's data interchange format

OpenSSF Scorecard

Copyright 2023 Google LLC

Overview

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can learn more about it in protobuf's documentation.

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.

Working With Protobuf Source Code

Most users will find working from supported releases to be the easiest path.

If you choose to work from the head revision of the main branch your build will occasionally be broken by source-incompatible changes and insufficiently-tested (and therefore broken) behavior.

If you are using C++ or otherwise need to build protobuf from source as a part of your project, you should pin to a release commit on a release branch.

This is because even release branches can experience some instability in between release commits.

Protobuf Compiler Installation

The protobuf 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 GitHub release page.

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 repository.

These pre-built binaries are only provided for released versions. If you want to use the github main 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
Ruby ruby
Go protocolbuffers/protobuf-go
PHP php
Dart dart-lang/protobuf
JavaScript protocolbuffers/protobuf-javascript

Quick Start

The best way to learn how to use protobuf is to follow the tutorials in our developer guide.

If you want to learn from code examples, take a look at the examples in the examples directory.

Documentation

The complete documentation is available at the Protocol Buffers doc site.

Support Policy

Read about our version support policy to stay current on support timeframes for the language libraries.
