Has anyone come across a good way, non-racy way to ensure that N tasks are guaranteed to be completed after a function is called? Essentially I have a “Close” function that must be guaranteed to block until all tasks are finished. Achieving this was pretty simple: wrap each task in an RLock, and then a Lock on close.
Example: https://play.golang.org/p/7lhBPUhkUE Now I want to write a solid test to guarantee Close will meet that requirement of all tasks must finish first for posterity. In that example, try commenting out the RLock/RUnlock on lines 25/26. You'll see that it no longer outputs many, if any, lines. I'm trying to prevent that from happening in the future by some cowboy refactor! All of the ways I can come up with involve Sleeping or launching more tasks than I _think_ can be finished in time--obviously not good! I feel like I must be missing some obvious way to test this and I'll end up feeling silly once someone replies with the solution. I'm okay with that! -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
