Go 1.5 is released - The Go Programming Language
Andrew Gerrand 19 August 2015 Today the Go project is proud to release Go 1.5, the sixth major stable release of Go. This release includes significant changes to the implementation. The compiler tool chain was translated from C to Go, removing the last vestiges of C code from the Go code base. The garbage collector was completely redesigned, yielding a dramatic reduction in garbage collection paus
Generating code - The Go Programming Language
Rob Pike 22 December 2014 A property of universal computation—Turing completeness—is that a computer program can write a computer program. This is a powerful idea that is not appreciated as often as it might be, even though it happens frequently. It’s a big part of the definition of a compiler, for instance. It’s also how the go test command works: it scans the packages to be tested, writes out a
Deploying Go servers with Docker - The Go Programming Language
Andrew Gerrand 26 September 2014 Introduction This week Docker announced official base images for Go and other major languages, giving programmers a trusted and easy way to build containers for their Go programs. In this article we’ll walk through a recipe for creating a Docker container for a simple Go web application and deploying that container to Google Compute Engine. If you’re not familiar w
Inside the Go Playground - The Go Programming Language
The playground service has three parts: A back end that runs on Google’s servers. It receives RPC requests, compiles the user program using the gc tool chain, executes the user program, and returns the program output (or compilation errors) as the RPC response. A front end that runs on Google App Engine. It receives HTTP requests from the client and makes corresponding RPC requests to the back end
Strings, bytes, runes and characters in Go - The Go Programming Language
Rob Pike 23 October 2013 Introduction The previous blog post explained how slices work in Go, using a number of examples to illustrate the mechanism behind their implementation. Building on that background, this post discusses strings in Go. At first, strings might seem too simple a topic for a blog post, but to use them well requires understanding not only how they work, but also the difference b
A conversation with the Go team - The Go Programming Language
We also hosted a similar session at I/O last year: Meet the Go team. There were many more questions from Google Moderator than we were able to answer in the short 40 minute session. Here we answer some of those we missed in the live session. Linking speed (and memory usage) for the gc toolchain are a known problem. Are there any plans to address this during the 1.2 cycle? Rob: Yes. We are always t
Go maps in action - The Go Programming Language
Andrew Gerrand 6 February 2013 Introduction One of the most useful data structures in computer science is the hash table. Many hash table implementations exist with varying properties, but in general they offer fast lookups, adds, and deletes. Go provides a built-in map type that implements a hash table. Declaration and initialization A Go map type looks like this: map[KeyType]ValueType where KeyT
A preview of Go version 1 - The Go Programming Language
Russ Cox 5 October 2011 We want to be able to provide a stable base for people using Go. People should be able to write Go programs and expect that they will continue to compile and run without change, on a timescale of years. Similarly, people should be able to write books about Go, be able to say which version of Go the book is describing, and have that version number still be meaningful much la
Go for App Engine is now generally available - The Go Programming Language
Andrew Gerrand 21 July 2011 The Go and App Engine teams are excited to announce that the Go runtime for App Engine is now generally available. This means you can take that Go app you’ve been working on (or meaning to work on) and deploy it to App Engine right now with the new 1.5.2 SDK. Since we announced the Go runtime at Google I/O we have continued to improve and extend Go support for the App E
