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
Working with Errors in Go 1.13 - The Go Programming Language
Damien Neil and Jonathan Amsterdam 17 October 2019 Introduction Go’s treatment of errors as values has served us well over the last decade. Although the standard library’s support for errors has been minimal—just the errors.New and fmt.Errorf functions, which produce errors that contain only a message—the built-in error interface allows Go programmers to add whatever information they desire. All i
testing package - testing - Go Packages
Package testing provides support for automated testing of Go packages. It is intended to be used in concert with the "go test" command, which automates execution of any function of the form func TestXxx(*testing.T) where Xxx does not start with a lowercase letter. The function name serves to identify the test routine. Within these functions, use the Error, Fail or related methods to signal failure
Contribution Workshop - The Go Programming Language
Steve Francia, Cassandra Salisbury, Matt Broberg, and Dmitri Shuralyov 9 August 2017 Event Overview by Steve During the community day at GopherCon, the Go team held two workshops where we worked with people to help them make their first contribution to the Go project. This was the first time the Go project has ever attempted anything like this. We had about 140 participants and about 35 people who

Networks. Clouds of CPUs. Loads of users. Our technology should help. That's where concurrency comes in. 3 Go supports concurrency Go provides: concurrent execution (goroutines) synchronization and mes

Codebase Refactoring (with help from Go)
1. Abstract Go should add the ability to create alternate equivalent names for types, in order to enable gradual code repair during codebase refactoring. This article explains the need for that ability and the implications of not having it for today’s large Go codebases. This article also examines some potential solutions, including the alias feature proposed during the development of (but not inc
Using Subtests and Sub-benchmarks - The Go Programming Language
Marcel van Lohuizen 3 October 2016 Introduction In Go 1.7, the testing package introduces a Run method on the T and B types that allows for the creation of subtests and sub-benchmarks. The introduction of subtests and sub-benchmarks enables better handling of failures, fine-grained control of which tests to run from the command line, control of parallelism, and often results in simpler and more ma

Go 1.6 is released - The Go Programming Language
Andrew Gerrand 17 February 2016 Today we release Go version 1.6, the seventh major stable release of Go. You can grab it right now from the download page. Although the release of Go 1.5 six months ago contained dramatic implementation changes, this release is more incremental. The most significant change is support for HTTP/2 in the net/http package. HTTP/2 is a new protocol, a follow-on to HTTP t
Go at Google: Language Design in the Service of Software Engineering - The Go Programming Language
1. Abstract (This is a modified version of the keynote talk given by Rob Pike at the SPLASH 2012 conference in Tucson, Arizona, on October 25, 2012.) The Go programming language was conceived in late 2007 as an answer to some of the problems we were seeing developing software infrastructure at Google. The computing landscape today is almost unrelated to the environment in which the languages being
