The Go Programming Language

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

This repository, microsoft/go, contains the infrastructure Microsoft uses to build Go. The submodule named go contains the Go source code. By default, the submodule's remote URL is the official GitHub mirror of Go, golang/go. The canonical Git repository for Go source code is located at https://go.googlesource.com/go.

This project is not involved in producing the official binary distributions of Go.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.

Why does this fork exist?

This repository produces a modified version of Go that can be used to build FIPS 140-2 compliant applications. Our goal is to share this implementation with others in the Go community who have the same requirement, and to merge this capability into upstream Go as soon as possible. See eng/doc/fips for more information about this feature and the history of FIPS 140-2 compliance in Go.

The binaries produced by this repository are also intended for general use within Microsoft instead of the official binary distribution of Go.

We call this repository a fork even though it isn't a traditional Git fork. Its branches do not share Git ancestry with the Go repository. However, the repository serves the same purpose as a Git fork: maintaining a modified version of the Go source code over time.

Support

This project follows the upstream Go Release Policy. This means we support each major release (1.X) until there are two newer major releases. A new Go major version is released every six months, so each Go major version is supported for about one year.

When upstream Go releases a new minor version (1.X.Y), we release a corresponding microsoft/go version that may also include fork-specific changes. This normally happens once a month. At any time, we may release a new revision (1.X.Y-Z) to fix an issue without waiting for the next upstream minor release. Revision releases are uncommon.

Each microsoft/go release is announced at the Microsoft for Go Developers blog. Check out the upstream golang-announce mailing list for a summary of the changes in each Go version.

There are a few additional support resources internal to Microsoft:

Download and install

We build the forked Go toolset with this list of OS/Arch combinations. To use a prebuilt copy of Go while targeting a platform that is not on this list, cross-compilation may be necessary.

linux_amd64
linux_armv6l
linux_arm64
windows_amd64

The following sections list the ways to get a build of the Microsoft fork of Go.

Docker Container Images

microsoft/go-images maintains and documents container images that are available on Microsoft Artifact Registry.

Azure Linux

The Azure Linux distribution includes builds of this Go fork.

In Azure Linux 2.0, the package msft-golang installs this fork.
In Azure Linux 3.0, the golang package installs this fork.

Binary archive

Signed builds of Go for several platforms are available as zip and tar.gz files.

Build from source

Pre-patched source tarball

The microsoft/go GitHub releases include a source tarball file ending in .src.tar.gz. After downloading and extracting the tar.gz file, build it using the upstream instructions.

Clone and build

This repository wraps the upstream Go repository and includes build scripts that automate some aspects of the build process. See eng/README.md for more details about the infrastructure.

Prerequisites:

PowerShell 6+
Go install from source prerequisites
- Exception: this repository's build script automatically downloads a bootstrap version of Go.

After cloning the repository and checking out the desired tag or commit, use the following build command:

pwsh eng/run.ps1 build -refresh

The resulting Go binary can then be found at go/bin/go.
