Shutting down goroutines quickly was needed so often that I wrote a package to help me with it. it is called idem, short for idempotent.
It uses the idea of an idempotent Close of a channel to signal that the goroutine should stop. This is because Go will panic if close a channel more than once (i.e. you wish to stop a goroutine from more than one place). This is a design flaw in channels, but we can work around it by using a mutex. Since the goroutine that wants the other goroutine to shutdown typically needs to wait until that is done, there is a reciprocal closing of another channel to indicate that the message has been received and will be acted on. https://github.com/glycerine/idem/blob/master/halter_test.go#L43 -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
