Method next

enterprise/coderd/x/chatd/chatd.go:653–668

next returns the delay before the next dial and sets giveUp once attempts exceed relayMaxRetries. Adapts the math from retry.Retrier.Wait (github.com/coder/retry/retrier.go) without blocking: the library's Wait returns 0 on the first call and sets Delay to Floor only after the sleep, so we clamp to

()

// Delay to Floor only after the sleep, so we clamp to Floor up
// front.
func (s *relayRetryState) next() (delay time.Duration, giveUp bool) {
	s.attempts++
	if s.attempts > relayMaxRetries {
		return 0, true
	}
	r := s.retrier
	d := time.Duration(float64(r.Delay) * r.Rate)
	if d > r.Ceil {
		d = r.Ceil
	}
	if d < r.Floor {
		d = r.Floor
	}
	r.Delay = d
	return d, false
}

// reset returns the state to the floor delay and zero attempts.
// Called after a successful dial or a relay target change.
