New unique package - The Go Programming Language
The Go Blog New unique package Michael Knyszek 27 August 2024 The standard library of Go 1.23 now includes the new unique package. The purpose behind this package is to enable the canonicalization of comparable values. In other words, this package lets you deduplicate values so that they point to a single, canonical, unique copy, while efficiently managing the canonical copies under the hood. You
Secure Randomness in Go 1.22 - The Go Programming Language
The Go Blog Secure Randomness in Go 1.22 Russ Cox and Filippo Valsorda 2 May 2024 Computers aren’t random. On the contrary, hardware designers work very hard to make sure computers run every program the same way every time. So when a program does need random numbers, that requires extra effort. Traditionally, computer scientists and programming languages have distinguished between two different ki
More powerful Go execution traces - The Go Programming Language
The Go Blog More powerful Go execution traces Michael Knyszek 14 March 2024 The runtime/trace package contains a powerful tool for understanding and troubleshooting Go programs. The functionality within allows one to produce a trace of each goroutine’s execution over some time period. With the go tool trace command (or the excellent open source gotraceui tool), one may then visualize and explore t
Organizing a Go module - The Go Programming Language
A common question developers new to Go have is “How do I organize my Go project?”, in terms of the layout of files and folders. The goal of this document is to provide some guidelines that will help answer this question. To make the most of this document, make sure you’re familiar with the basics of Go modules by reading the tutorial and managing module source. Go projects can include packages, co
Experimenting with project templates - The Go Programming Language
Cameron Balahan 31 July 2023 When you start a new project in Go, you might begin by cloning an existing project. That way, you can start with something that already works, making incremental changes instead of starting from scratch. For a long time now, we have heard from Go developers that getting started is often the hardest part. New developers coming from other languages expect guidance on a d
Govulncheck v1.0.0 is released! - The Go Programming Language
Julie Qiu, for the Go security team 13 July 2023 We are excited to announce that govulncheck v1.0.0 has been released, along with v1.0.0 of the API for integrating scanning into other tools! Go’s support for vulnerability management was first announced last September. We have made several changes since then, culminating in today’s release. This post describes Go’s updated vulnerability tooling, an
An Introduction To Generics - The Go Programming Language
The Go 1.18 release adds support for generics. Generics are the biggest change we’ve made to Go since the first open source release. In this article we’ll introduce the new language features. We won’t try to cover all the details, but we will hit all the important points. For a more detailed and much longer description, including many examples, see the proposal document. For a more precise descrip
Fuzzing is Beta Ready - The Go Programming Language
Katie Hockman and Jay Conrod 3 June 2021 We are excited to announce that native fuzzing is ready for beta testing on tip! Fuzzing is a type of automated testing which continuously manipulates inputs to a program to find issues such as panics or bugs. These semi-random data mutations can discover new code coverage that existing unit tests may miss, and uncover edge case bugs which would otherwise g
Effective Go - The Go Programming Language
Introduction Go is a new language. Although it borrows ideas from existing languages, it has unusual properties that make effective Go programs different in character from programs written in its relatives. A straightforward translation of a C++ or Java program into Go is unlikely to produce a satisfactory result—Java programs are written in Java, not Go. On the other hand, thinking about the prob
Command PATH security in Go - The Go Programming Language
Russ Cox 19 January 2021 Today’s Go security release fixes an issue involving PATH lookups in untrusted directories that can lead to remote execution during the go get command. We expect people to have questions about what exactly this means and whether they might have issues in their own programs. This post details the bug, the fixes we have applied, how to decide whether your own programs are vu
Eleven Years of Go - The Go Programming Language
Russ Cox, for the Go team 10 November 2020 Today we celebrate the eleventh birthday of the Go open source release. The parties we had for Go turning 10 seem like a distant memory. It’s been a tough year, but we’ve kept Go development moving forward and accumulated quite a few highlights. In November, we launched go.dev and pkg.go.dev shortly after Go’s 10th birthday. In February, the Go 1.14 relea
A new Go API for Protocol Buffers - The Go Programming Language
Joe Tsai, Damien Neil, and Herbie Ong 2 March 2020 Introduction We are pleased to announce the release of a major revision of the Go API for protocol buffers, Google’s language-neutral data interchange format. Motivations for a new API The first protocol buffer bindings for Go were announced by Rob Pike in March of 2010. Go 1 would not be released for another two years. In the decade since that fi
Go 1.13 Release Notes - The Go Programming Language
Introduction to Go 1.13 The latest Go release, version 1.13, arrives six months after Go 1.12. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. As of Go 1.13, the go command by default downloads and authenticates modul
Module Mirror and Checksum Database Launched - The Go Programming Language
Katie Hockman 29 August 2019 We are excited to share that our module mirror, index, and checksum database are now production ready! The go command will use the module mirror and checksum database by default for Go 1.13 module users. See proxy.golang.org/privacy for privacy information about these services and the go command documentation for configuration details, including how to disable the use
Experiment, Simplify, Ship - The Go Programming Language
We experiment with Go as it exists now, to understand it better, learning what works well and what doesn’t. Then we experiment with possible changes, to understand them better, again learning what works well and what doesn’t. Based on what we learn from those experiments, we simplify. And then we experiment again. And then we simplify again. And so on. And so on. The Four R’s of Simplifying During
Go 1.12 Release Notes - The Go Programming Language
Introduction to Go 1.12 The latest Go release, version 1.12, arrives six months after Go 1.11. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language There are no changes to the language specification
Portable Cloud Programming with Go Cloud - The Go Programming Language
Eno Compton and Cassandra Salisbury 24 July 2018 Introduction Today, the Go team at Google is releasing a new open source project, Go Cloud, a library and tools for developing on the open cloud. With this project, we aim to make Go the language of choice for developers building portable cloud applications. This post explains why we started this project, the details of how Go Cloud works, and how t
Go 1.9 is released - The Go Programming Language
Francesc Campoy 24 August 2017 Today the Go team is happy to announce the release of Go 1.9. You can get it from the download page. There are many changes to the language, standard library, runtime, and tooling. This post covers the most significant visible ones. Most of the engineering effort put into this release went to improvements of the runtime and tooling, which makes for a less exciting an
