示例1: 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
}
if !currentState.HasAccount(from) {
return ErrNonExistentAccount
}
// Last but not least check for nonce errors
if currentState.GetNonce(from) > tx.Nonce() {
return ErrNonce
}
// Check the transaction doesn't exceed the current
// block limit gas.
if pool.gasLimit().Cmp(tx.Gas()) < 0 {
return ErrGasLimit
}
// 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.
if tx.Value().Cmp(common.Big0) < 0 {
return ErrNegativeValue
}
// Transactor should have enough funds to cover the costs
// cost == V + GP * GL
if currentState.GetBalance(from).Cmp(tx.Cost()) < 0 {
return ErrInsufficientFunds
}
// Should supply enough intrinsic gas
if tx.Gas().Cmp(IntrinsicGas(tx.Data())) < 0 {
return ErrIntrinsicGas
}
return nil
}
示例2: newRPCPendingTransaction
// newRPCPendingTransaction returns a pending transaction that will serialize to the RPC representation
func newRPCPendingTransaction(tx *types.Transaction) *RPCTransaction {
from, _ := tx.From()
return &RPCTransaction{
From: from,

GasLimit: rpc.NewHexNumber(t.Gas()),
GasPrice: rpc.NewHexNumber(t.GasPrice()),
Hash: t.Hash(),

示例4: addTx
// addTx will add a transaction to the pending (processable queue) list of transactions
func (pool *TxPool) addTx(hash common.Hash, addr common.Address, tx *types.Transaction) {
// init delayed since tx pool could have been started before any state sync

pool.pending[hash] = tx
// Increment the nonce on the pending state. This can only happen if
// the nonce is +1 to the previous one.
pool.pendingState.SetNonce(addr, tx.Nonce()+1)
// Notify the subscribers. This event is posted in a goroutine
// because it's possible that somewhere during the post "Remove transaction"
// gets called which will then wait for the global tx pool lock and deadlock.
go pool.eventMux.Post(TxPreEvent{tx})
}
}
示例5: 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6: 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)
if err := rlp.DecodeBytes(common.FromHex(encodedTx), tx); err != nil {
return "", err
