I'm trying to understand how the 'select' statement works internally. The execution process of select as described in https://golang.org/ref/spec#Select_statements says on number 2: "If one or more of the communications can proceed, a single one that can proceed is chosen via a uniform pseudo-random selection."
However, in this example: https://play.golang.org/p/1GKsbhES8s I've defined two cases each calling a different function: A() and B(). When I execute this code it seems to evaluate both functions (it waits till the longest sleep in A and B finishes but returns a random 1 or 2). Does this means that select choses a random case (as stated in the docs) but evaluates both cases? Does anyone know what kind of concurrency 'select' uses internally to evaluate both functions? Thanks for your help, Pablo Note: The Go Playground doesn't seem to return random responses as the ones I see when I run the same code on my local computer. It might be related to internal caching effects. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
