Disabling Direct Mapping Feature Output on Local Test Validator
As a developer working with Solana, you are probably familiar with the importance of testing and validation. One feature that can significantly impact your development process is the direct mapping feature output, also known as the “feature gate” or “devnet only” setting.
In this article, we will explore how to disable the direct mapping feature gate on a local test validator for Solana.
What is direct mapping?
Direct mapping allows users to create and manage their own nodes without interacting with the mainnet. This feature is designed to provide a more seamless testing experience and ensure that your code runs correctly in isolation.
However, as we mentioned earlier, direct mapping feature input can pose a security risk on local test validators, as it requires users to have access to mainnet features, including the ability to create new nodes.
Why disable Direct Mapping feature access?
Disabling Direct Mapping feature output provides several benefits:
- Improved security: By not exposing your user accounts to backend features, you can significantly reduce the risk of unauthorized access and data breaches.
- Faster testing: Local test validators enable faster testing and code validation without relying on backend infrastructure.
- Better performance:
Without the need to create new nodes or manage complex network configurations, local test validators can work more efficiently.
How to disable Direct Mapping feature ports on a local test validator
To disable Direct Mapping feature output on your local test validator:
Method 1: Using the Solana CLI
You can use the solana CLI command-line interface (CLI) to switch the feature port. Here’s an example:
solana config feature-gate --set true
Replace with the name of the feature you want to disable.
For example, to disable the direct mapping feature port, run:
solana config feature-gate direct-mapping --set true
Method 2: Using a configuration file
You can also configure feature ports using a configuration file. Create a new file named config.json in your Solana project directory with the following content:
{
"feature-gates": {
"direct mapping": {
"enabled": true
}
}
}
Then use solana config feature-gate command to enable/disable the feature.
Conclusion
Disabling the direct mapping feature output on your local test validator provides several security, testing, and performance benefits. By following these steps, you can safely disable this feature and provide a more controlled development environment for your Solana projects. Remember to always follow best practices when working with sensitive features such as direct mapping feature access.
