Hamid Rkp modernized the DNS resolution stack in the denoland/deno repository by replacing the unmaintained trust-dns library with HickoryDNS within the deno_net extension. This work involved updating dependencies and refactoring imports to ensure compatibility with the new DNS library, directly addressing reliability and long-term maintainability concerns. Using Rust, Hamid focused on dependency management and networking, enabling future support and reducing the risk associated with outdated libraries. The changes were delivered as a targeted feature refactor, demonstrating a clear understanding of the project’s infrastructure needs and providing a solid foundation for ongoing DNS functionality within the Deno ecosystem.
