Method release

pkg/server/idempotency.go:55–68

release forgets key so a subsequent request with it is processed again. Used to roll back a reservation when the reserved operation fails, so a failure is retryable rather than being mistaken for a completed duplicate.

(key string)

// failure is retryable rather than being mistaken for a completed duplicate.
func (c *idempotencyCache) release(key string) {
	c.mu.Lock()
	defer c.mu.Unlock()

		return
	}
	delete(c.set, key)
	for i, k := range c.ring {
		if k == key {
			c.ring = append(c.ring[:i], c.ring[i+1:]...)
			break
		}
