how to compare the from's funds when send tx

kazaff commented 6 years ago

Hi there,

I wonder that when we create a transaction and send it with eth_sendRawTransaction RPC method, how the Geth can make sure the error(Insufficient funds for gas * price + value) was happened?

I mean i know the source code in here:

        // Transactor should have enough funds to cover the costs
    // cost == V + GP * GL
    if b := currentState.GetBalance(from); b.Cmp(tx.Cost()) < 0 {
        return core.ErrInsufficientFunds
    }

But I would like to know the detail about currentState.GetBalance(from) like:

DO the from address's balance include any transaction in pending? or just only contain completed transaction?

Thanks in advance!!

The balance is computed from the current chain head and does not include pending transactions.
