Method Lock

internal/lock/lock.go:216–230

Lock attempts to acquire all locks in deterministic order. If any lock acquisition fails, all previously acquired locks are released (rollback). Parameters: - ctx: The context for managing the lock request lifecycle. - timeout: The time-to-live (TTL) for each lock. Returns an error if any lock could

(ctx context.Context, timeout time.Duration)

// - timeout: The time-to-live (TTL) for each lock.
// Returns an error if any lock could not be acquired.
func (m *MultiLocker) Lock(ctx context.Context, timeout time.Duration) error {
	acquiredCount := 0

	for _, locker := range m.lockers {
		err := locker.Lock(ctx, timeout)
		if err != nil {
			// Rollback: release all previously acquired locks in reverse order
			m.rollback(ctx, acquiredCount)
			return fmt.Errorf("failed to acquire lock for key %s: %w", locker.key, err)
		}
		acquiredCount++
	}

	return nil
}

// WaitLock tries to acquire all locks within a specified waiting period.
// It will attempt to acquire locks with exponential backoff if any lock is held.
