Worked on the oven-sh/bun repository to address a critical memory leak in the TLS upgrade path, focusing on scenarios where applications use tls.connect with raw TCP sockets. Applied expertise in memory management and network programming using Zig, JavaScript, and TypeScript to implement a robust cleanup sequence that ensures proper resource release and garbage collection. Introduced defer-based cleanup, reference counting, and regression tests to validate the fix across various TLS suites and real-world drivers like MongoDB Node.js and mysql2. This work stabilized long-running services by preventing unbounded memory growth, improving reliability for production workloads that rely on secure socket upgrades.
