示例1: InternalHeartbeatTxn
// InternalHeartbeatTxn updates the transaction status and heartbeat
// timestamp after receiving transaction heartbeat messages from
// coordinator. Returns the updated transaction.
func (r *Range) InternalHeartbeatTxn(batch engine.Engine, ms *engine.MVCCStats,
args *proto.InternalHeartbeatTxnRequest, reply *proto.InternalHeartbeatTxnResponse) {
key := keys.TransactionKey(args.Txn.Key, args.Txn.ID)
var txn proto.Transaction
ok, err := engine.MVCCGetProto(batch, key, proto.ZeroTimestamp, true, nil, &txn)
if err != nil {
reply.SetGoError(err)
return
}
// If no existing transaction record was found, initialize
// to the transaction in the request header.
if !ok {
gogoproto.Merge(&txn, args.Txn)
}
if txn.Status == proto.PENDING {
if txn.LastHeartbeat == nil {
txn.LastHeartbeat = &proto.Timestamp{}
}
if txn.LastHeartbeat.Less(args.Header().Timestamp) {
*txn.LastHeartbeat = args.Header().Timestamp
}
if err := engine.MVCCPutProto(batch, ms, key, proto.ZeroTimestamp, nil, &txn); err != nil {
reply.SetGoError(err)
return
}
}
reply.Txn = &txn
}示例2: InternalHeartbeatTxn
// InternalHeartbeatTxn updates the transaction status and heartbeat
// timestamp after receiving transaction heartbeat messages from
// coordinator. Returns the udpated transaction.
func (r *Range) InternalHeartbeatTxn(args *proto.InternalHeartbeatTxnRequest, reply *proto.InternalHeartbeatTxnResponse) {
// Create the actual key to the system-local transaction table.
key := engine.MakeKey(engine.KeyLocalTransactionPrefix, args.Key)
var txn proto.Transaction

}示例3: InternalHeartbeatTxn
// InternalHeartbeatTxn updates the transaction status and heartbeat
// timestamp after receiving transaction heartbeat messages from
// coordinator. The range will return the current status for this
// transaction to the coordinator.

// Create the actual key to the system-local transaction table.
key := engine.MakeKey(engine.KeyLocalTransactionPrefix, args.Key)
