Worked on the oven-sh/bun repository to address a stability issue affecting Bun install when using HTTP proxies with cached packages. Focused on HTTP protocol handling and network programming, the solution involved implementing unconditional handling for 304 and other no-body status codes in Zig, ensuring correct content length management through CONNECT tunnels. Added a comprehensive regression test in TypeScript to simulate proxy scenarios and verify that consecutive installs no longer hang. This targeted bug fix improved install reliability and performance, reduced the risk of prolonged install delays, and enhanced CI stability, demonstrating careful attention to protocol correctness and robust testing practices.
