示例1: add
// validate and queue transactions.
func (self *TxPool) add(tx *types.Transaction) error {
hash := tx.Hash()
if self.pending[hash] != nil {
return fmt.Errorf("Known transaction (%x)", hash[:4])
}
err := self.validateTx(tx)
if err != nil {
return err
}
self.queueTx(hash, tx)
if glog.V(logger.Debug) {
var toname string
if to := tx.To(); to != nil {
toname = common.Bytes2Hex(to[:4])
} else {
toname = "[NEW_CONTRACT]"
}
// we can ignore the error here because From is
// verified in ValidateTransaction.
f, _ := tx.From()
from := common.Bytes2Hex(f[:4])
glog.Infof("(t) %x => %s (%v) %x\n", from, toname, tx.Value, hash)
}
return nil
}
示例2: validateTx
// validateTx checks whether a transaction is valid according
// to the consensus rules.
func (pool *TxPool) validateTx(tx *types.Transaction) error {
// Validate sender
var (
from common.Address
err error
)
local := pool.localTx.contains(tx.Hash())
// Drop transactions under our own minimal accepted gas price
if !local && pool.minGasPrice.Cmp(tx.GasPrice()) > 0 {
return ErrCheap
}
// Validate the transaction sender and it's sig. Throw
// if the from fields is invalid.
if from, err = tx.From(); err != nil {
return ErrInvalidSender
}
// Make sure the account exist. Non existent accounts
// haven't got funds and well therefor never pass.
currentState, err := pool.currentState()
if err != nil {
return err
}

return ErrNonExistentAccount
}
// Last but not least check for nonce errors

return ErrNonce

// Check the transaction doesn't exceed the current
// block limit gas.
if pool.gasLimit().Cmp(tx.Gas()) < 0 {

// Transactions can't be negative. This may never happen
// using RLP decoded transactions but may occur if you create
// a transaction using the RPC for example.

return nil
}
示例3: AddTx
// AddTx adds a transaction to the generated block. If no coinbase has
// been set, the block's coinbase is set to the zero address.
//
// AddTx panics if the transaction cannot be executed. In addition to
// the protocol-imposed limitations (gas limit, etc.), there are some
// further limitations on the content of transactions that can be
// added. Notably, contract code relying on the BLOCKHASH instruction
// will panic during execution.

示例4: newRPCPendingTransaction
// newRPCPendingTransaction returns a pending transaction that will serialize to the RPC representation

示例6: ApplyTransaction
// ApplyTransaction attemps to apply a transaction to the given state database
// and uses the input parameters for its environment.
//
// ApplyTransactions returns the generated receipts and vm logs during the
// execution of the state transition phase.
func ApplyTransaction(bc *BlockChain, gp *GasPool, statedb *state.StateDB, header *types.Header, tx *types.Transaction, usedGas *big.Int) (*types.Receipt, vm.Logs, *big.Int, error) {

示例7: SendRawTransaction
// SendRawTransaction will add the signed transaction to the transaction pool.
// The sender is responsible for signing the transaction and using the correct nonce.
func (s *PublicTransactionPoolAPI) SendRawTransaction(encodedTx string) (string, error) {
tx := new(types.Transaction)

示例8: SetLocal
// SetLocal marks a transaction as local, skipping gas price
// check against local miner minimum in the future
