• singleflight - a duplicate function call suppression mechanism

• syncmap - a concurrent map implementation

This package provides most of the code for running a godoc server.

This repository holds packages for writing tools that work directly with Go module mechanics. That is, it is for direct manipulation of Go modules themselves.

The specific case of loading packages should still be done by invoking the go command, which remains the single point of truth for package loading algorithms.
