Suppose I have a long-running computation that I wish to be cancelable via a context. By this I mean something that's just churning away on some computation, not blocking on a syscall or I/O operation or anything like that. Should I just poll ctx.Err() periodically in the inner loop of my computation?
Also, can anyone give any insight into approximately how costly context.Err() is for the contexts constructed in the context package -- I don't want my computation to be dominated by checking for cancellation! -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
