Bash Script for EVM Initialization and Configuration
Winnode opened this issue · comments
The provided bash script aims to perform initialization and configuration of the EVM (Ethereum Virtual Machine). However, there are several potential issues that need to be addressed to enhance the script's security, stability, and overall performance.
Recommended Improvements:
-
Parameter Validation:
- Add validation to check whether the
$1
(MONIKER) and$2
(RPC URL) parameters have been provided before proceeding with the script execution. This will help prevent errors that may occur due to invalid inputs. - Example improvement:
MONIKER=$1 RPC=$2 if [[ -z $MONIKER ]]; then echo >&2 "Invalid MONIKER" exit 1 fi if [[ -z $RPC ]]; then echo >&2 "Invalid RPC URL" exit 1 fi
- Add validation to check whether the
-
Error Handling:
- Add error handling when executing the
SGX_MODE=SW make build-enclave
andmake install
commands. This will help to know if there are any issues during the compilation or installation process and provide better information about those errors. - Example improvement:
cd $HOME/chain/ && git pull && SGX_MODE=SW make build-enclave if [ $? -ne 0 ]; then echo >&2 "Failed to compile SGX_MODE=SW" exit 1 fi cd $HOME/chain/ && make install if [ $? -ne 0 ]; then echo >&2 "Failed to install" exit 1 fi
- Add error handling when executing the
-
Optimize Commands:
- Simplify some sequential commands to improve code readability and compactness.
- Example improvement:
cd $HOME/chain/ && git pull && SGX_MODE=SW make build-enclave && make install
-
Appropriate Access Rights:
- Ensure that this script is executed with appropriate access rights for the
sudo rm -rf $HOMEDIR
command. This command has the potential to delete directories and their contents, which could have significant impacts on the system. - Use with caution and ensure that root access is not misused in this script.
- Ensure that this script is executed with appropriate access rights for the
-
Environment Testing:
- Ensure that the environment required by the script is properly configured, including variables like
$HOME/chain/
and external dependencies such asjq
and theswisstronikd
service. Make sure that all dependencies are met before running the script.
- Ensure that the environment required by the script is properly configured, including variables like
-
Default Value Replacements:
- Some values in the
genesis.json
file will be replaced. Ensure that these changes align with the needs and purposes of the initialized and configured EVM.
- Some values in the
