Hi all, I'm trying to understand the idioms around cancellation of contexts. I've read the godoc and the relevant blog (https://blog.golang.org/context).
Should you always call the cancelFunc of a cancellable context? Or should it only be called if the operation is terminated before successful completion? The godoc says: "Canceling this context releases resources associated with it, so code should call cancel as soon as the operations running in this Context complete." This implies to me that it must always be called. If so, then how can the Err function report the reason for the termination of the operation? The godoc says "Err returns Canceled if the context was canceled" So if cancel must always be called to release resources, Err will always return a value of Canceled.
