geth: can not resend transaction - transaction not found

Question

I'm trying to resend a transaction unrecognized by network with increased gas price:

tx = eth.pendingTransactions[0]
eth.resend(tx, web3.toWei(0.5, "szabo"))

What I'm getting is:

Transaction 0x1c6f5e5ffd2109167fa2bad731224d5e5b3cec8a654debffaa665bdc12969020 not found
at web3.js:3119:20
at web3.js:6023:15
at web3.js:4995:36

What's wrong?

Answer 1

Running this patch at the console works for me:

eth.resend = function (tx, gasPrice, gas) {
  if (gasPrice) {
    tx.gasPrice = gasPrice;
  }
  if (gas) {
    tx.gas = gas;
  }
  tx.data = tx.input;
  return eth.sendTransaction(tx);
};

I prefer to also add this convenience version:

eth.resendgwei = function (tx, gasPriceInGwei, gas) {
  if (gasPriceInGwei) {
    return eth.resend(tx, web3.toWei(gasPriceInGwei, 'gwei'), gas);
  }
  else {
    return eth.resend(tx, null, gas);
  }
};

Now, if your pending transaction is stuck because the gas price is too low, you can speed it up with:

eth.resendgwei(eth.pendingTransactions[0], 51);
