Example 1 with BlockchainConfig

use of org.ethereum.config.BlockchainConfig in project rskj by rsksmart.

the class TransactionExecutor method create.

private void create() {
    RskAddress newContractAddress = tx.getContractAddress();
    if (isEmpty(tx.getData())) {
        mEndGas = toBI(tx.getGasLimit()).subtract(BigInteger.valueOf(basicTxCost));
        cacheTrack.createAccount(newContractAddress);
    } else {
        ProgramInvoke programInvoke = programInvokeFactory.createProgramInvoke(tx, txindex, executionBlock, cacheTrack, blockStore);
        this.vm = new VM(vmConfig, precompiledContracts);
        BlockchainConfig configForBlock = config.getBlockchainConfig().getConfigForBlock(executionBlock.getNumber());
        this.program = new Program(vmConfig, precompiledContracts, configForBlock, tx.getData(), programInvoke, tx);
        // reset storage if the contract with the same address already exists
        // TCK test case only - normally this is near-impossible situation in the real network
        ContractDetails contractDetails = program.getStorage().getContractDetails(newContractAddress);
