08 — Resources

The primary sources

Everything in this library can be checked against these. Where a page says what Go promises, it links one of them.

• The Go Programming Language Specification ↗ — Go statements, Channel types, Send statements, Select statements, Program execution.
• The Go Memory Model ↗ — what one goroutine may assume about another's writes, and which operations synchronize.
• Packages: sync ↗, sync/atomic ↗, context ↗, testing/synctest ↗.
• Data Race Detector ↗ — how -race works, what it costs, and its exit status.
• Effective Go: Concurrency ↗ and the Go blog's Share Memory By Communicating ↗ — the idiom behind chapters 02 and 06.
• Go Concurrency Patterns: Pipelines and cancellation ↗ — the source of chapter 06's first lessons.
• Testing concurrent code with testing/synctest ↗ and the Go 1.25 release notes ↗ — synctest and WaitGroup.Go.

The Concurrency library keeps a longer list of concurrency books for every language, with their chapters: books ↗.

The same ideas in other languages

Each Go lesson's In other languages section links its counterparts. The Concurrency library's concept map ↗ goes the other way: a page per idea — goroutine, channel, select, mutex, cancellation, pipeline, race detector — with the construct in each language, and a link back to the lesson here.
