Types

type Detector

type Detector struct {
	// contains filtered or unexported fields
}

Detector detects deadlock.

func NewDetector

func NewDetector() *Detector

NewDetector creates a new Detector.

func (*Detector) CleanUp

func (d *Detector) CleanUp(txn uint64)

CleanUp removes the wait for entry for the transaction.

func (*Detector) CleanUpWaitFor

func (d *Detector) CleanUpWaitFor(txn, waitForTxn, keyHash uint64)

CleanUpWaitFor removes a key in the wait for entry for the transaction.

func (*Detector) Detect

func (d *Detector) Detect(sourceTxn, waitForTxn, keyHash uint64) *ErrDeadlock

Detect detects deadlock for the sourceTxn on a locked key.

func (*Detector) Expire

func (d *Detector) Expire(minTS uint64)

Expire removes entries with TS smaller than minTS.

type ErrDeadlock

type ErrDeadlock struct {
	KeyHash uint64
}

ErrDeadlock is returned when deadlock is detected.

func (*ErrDeadlock) Error

func (e *ErrDeadlock) Error() string
