joincontext

Build Status GoDoc

Package joincontext provides a way to combine two contexts. For example it might be useful for grpc server to cancel all handlers in addition to provided handler context.

For additional info see godoc page

Example

	ctx1, cancel1 := context.WithCancel(context.Background())
	defer cancel1()
	ctx2 := context.Background()

	ctx, cancel := joincontext.Join(ctx1, ctx2)
	defer cancel()
	select {
	case <-ctx.Done():
	default:
		fmt.Println("context alive")
	}

	cancel1()

	// give some time to propagate
	time.Sleep(100 * time.Millisecond)

	select {
	case <-ctx.Done():
		fmt.Println(ctx.Err())
	default:
	}

	// Output: context alive
	// context canceled
