Graceful stopping in Go â€” Richard Crowleyâ€™s blog
Itâ€™s rude to deploy early and often if deploys interrupt user requests so we build our Go services at Betable to stop gracefully without interrupting anyone.Â The idea is to stop listening, presumably so a new process can take over, and let all open connections respond to any in-progress requests before finally stopping service.Â Incidentally, we use goagain to restart without even stopping listen

Smaller Go 1.7 binaries - The Go Programming Language
David Crawshaw 18 August 2016 Introduction Go was designed for writing servers. That is how it is most widely used today, and as a result a lot of work on the runtime and compiler is focused on issues that matter to servers: latency, ease of deployment, precise garbage collection, fast startup time, performance. As Go gets used for a wider variety of programs, there are new issues that must be con

Matt's Musings: Handling Errors in HTTP Handlers in Go
What do you do when things go wrong in your HTTP handlers? This post briefly examines three possible ways to handle errors in web applications. It is a recap of this lightning talk. I will not get into the philosophies of error handling or the details of how to implement an error handler. But the relationship between HTTP handlers and error handlers is an important one to consider. No one way is s

Synchronize goroutines in your tests
Jack of all Trades, Professional Software Craftsman I have been working on an emulator for the MOS 6502 Microprocessor, written in Go. As part of this package I have also implemented a minimal 6551 Asynchronous Communication Interface Adapter. The 6551 provides serial IO and is easy to use in combination with the 6502. When the microprocessor writes a byte to the 6551 it is stored in the tx (trans

How to Wait for All Goroutines to Finish Executing Before Continuing | I care, I share, I'm Nathan LeClaire.
EDIT: As pointed out by effenn in this Reddit comment, a lot of information in this article is â€œdangerously inaccurateâ€. OOPS! Iâ€™ve written a followup/correction article here for your viewing pleasure, but Iâ€™m leaving this article up for â€œhistorical purposesâ€. Goroutines and channels are one of Goâ€™s nicest language features. They provide a rather headache-free way to use the power of concurrency i
