示例1: TestRemoveLeaseIfExpiring

func TestRemoveLeaseIfExpiring(t *testing.T) {
	defer leaktest.AfterTest(t)()

	p := planner{}
	mc := hlc.NewManualClock(0)
	p.leaseMgr = &LeaseManager{LeaseStore: LeaseStore{clock: hlc.NewClock(mc.UnixNano)}}
	p.leases = make([]*LeaseState, 0)
	txn := client.Txn{}
	p.setTxn(&txn)

	if p.removeLeaseIfExpiring(nil) {
		t.Error("expected false with nil input")
	}

	// Add a lease to the planner.
	d := int64(LeaseDuration)
	l1 := &LeaseState{expiration: parser.DTimestamp{Time: time.Unix(0, mc.UnixNano()+d+1)}}
	p.leases = append(p.leases, l1)
	et := hlc.Timestamp{WallTime: l1.Expiration().UnixNano()}
	txn.UpdateDeadlineMaybe(et)

	if p.removeLeaseIfExpiring(l1) {
		t.Error("expected false wih a non-expiring lease")
	}
	if !p.txn.GetDeadline().Equal(et) {
		t.Errorf("expected deadline %s but got %s", et, p.txn.GetDeadline())
	}

	// Advance the clock so that l1 will be expired.
	mc.Increment(d + 1)

	// Add another lease.
	l2 := &LeaseState{expiration: parser.DTimestamp{Time: time.Unix(0, mc.UnixNano()+d+1)}}
	p.leases = append(p.leases, l2)
	if !p.removeLeaseIfExpiring(l1) {
		t.Error("expected true with an expiring lease")
	}
	et = hlc.Timestamp{WallTime: l2.Expiration().UnixNano()}
	txn.UpdateDeadlineMaybe(et)

	if !(len(p.leases) == 1 && p.leases[0] == l2) {
		t.Errorf("expected leases to contain %s but has %s", l2, p.leases)
	}

	if !p.txn.GetDeadline().Equal(et) {
		t.Errorf("expected deadline %s, but got %s", et, p.txn.GetDeadline())
	}

示例2: setTxnTimestamps

// setTxnTimestamps sets the transaction's proto timestamps and deadline
// to ts. This is for use with AS OF queries, and should be called in the
// retry block (except in the case of prepare which doesn't use retry). The
// deadline-checking code checks that the `Timestamp` field of the proto
// hasn't exceeded the deadline. Since we set the Timestamp field each retry,
// it won't ever exceed the deadline, and thus setting the deadline here is
// not strictly needed. However, it doesn't do anything incorrect and it will
// possibly find problems if things change in the future, so it is left in.
func setTxnTimestamps(txn *client.Txn, ts hlc.Timestamp) {
	txn.Proto.Timestamp = ts
	txn.Proto.OrigTimestamp = ts
	txn.Proto.MaxTimestamp = ts
	txn.UpdateDeadlineMaybe(ts)
}
