Show HN: A pure ARM64 Assembly web server, now on Linux with CGI for no reason
TL;DR
Web servers often rely on complex libraries, which can introduce overhead and dependencies. ymawky is a web server written entirely in ARM64 assembly language, designed to operate without the standard C library (libc) and using a syscall-only approach. This Linux port allows for efficient file serving with minimal resource usage, demonstrating the potential of low-level programming in web server development.
✦ Why It Matters
Engineers can leverage low-level programming techniques to create efficient, lightweight web servers with minimal dependencies.
Key Takeaways
- Explore low-level programming for web server efficiency.
- Consider syscall-only architectures to reduce dependencies.
- Utilize ARM64 assembly for performance-critical applications.
- Implement a fork-per-connection model for enhanced security.
Full Summary
Web servers typically depend on high-level libraries that can add complexity and resource overhead. To address this, ymawky was developed as a pure ARM64 assembly web server, which operates without the standard C library (libc) and employs a syscall-only architecture.
Originally created for MacOS, this version is a fully functional port for Linux. The server uses a fork-per-connection model, meaning it creates a new process for each incoming request, enhancing isolation and security.
Users can compile the server with or without debugging symbols, and it requires a specific directory structure for serving files. By returning only valid JSON responses, ymawky showcases the efficiency of low-level programming in web server design, potentially inspiring engineers to explore similar approaches in their projects.
