Go: Building Web Applications

A little bit about CSP

We touched on CSP briefly in the previous chapter, but it's worth exploring a bit more in the context of how Go's concurrency model operates.

CSP evolved in the late 1970s and early 1980s through the work of Sir Tony Hoare and is still in the midst of evolution today. Go's implementation is heavily based on CSP, but it neither entirely follows all the rules and conventions set forth in its initial description nor does it follow its evolution since.

One of the ways in which Go differs from true CSP is that as it is defined, a process in Go will only continue so long as there exists a channel ready to receive from that process. We've already encountered a couple of deadlocks that were the result of a listening channel with nothing ...
