PROFILE
Nikolay Govorov
Over six months, contributed to the lightpanda-io/browser repository by building and refining core browser automation infrastructure using Zig and C/C++. Delivered features such as a modular CSS tokenizer, a multi-CDP architecture for concurrent browser sessions, and a centralized configuration model to streamline initialization. Enhanced network programming with a global runtime, TCP keepalive, and robust HTTP handling, while improving thread safety and memory management through atomic operations and integration with Thread Sanitizer. Addressed critical bugs in session teardown and garbage collection, reducing crash risk and improving reliability. The work emphasized maintainability, scalability, and safe cross-platform backend development practices throughout.

May 1, 2026May 2026 monthly summary for lightpanda-io/browser focused on stability and lifecycle improvements in the browser component. Addressed crashes during session teardown and garbage collection by tightening memory-pressure handling and using weak callbacks in V8 GC during deinitialization. Also ensured CDP browser context cleanup is deferred until the connection closes to avoid dereferencing freed state during script evaluation. These changes reduce crash risk across teardown paths and improve reliability for both automated tests and end-user sessions. Commits involved: 5cc8a0daff900f65b45725db063e0186db580ee6 (Fix v8 crash) and e5a9f8ba2ef040ca64bac6db3f3ce3251131824c (Fix ony more crash).

Feb 1, 2026February 2026: Achieved significant architectural modernization and reliability improvements in lightpanda-io/browser. Key deliverables: - Implemented multi-CDP architecture with a dedicated CDP thread and per-CDP HttpClient, enabling concurrent CDP connections and improved responsiveness. - Moved IO loops from Server to CDP Client and centralized curl handling in modular layers (Connection, Net) with a type-safe curl wrapper for safer API usage. - Strengthened core thread-safety across ArenaPool, Robots and Env; introduced strict visibility for Net functions. - Reworked build and dependency management: switched to Zig package manager, modularized C libraries, updated libcurl, and increased CI memory limit for reproducible builds. Major bugs fixed: - Fixed race condition in sighandler. - Fixed use-after-free in Fetch. - Fixed a typo in build.zig. Overall impact: - Improved scalability to support multiple CDP connections, reduced risk from race conditions, and enhanced build stability and reproducibility, enabling faster iteration and safer deployments. Technologies/skills demonstrated: - Zig, multi-CDP architecture, thread safety, modular networking, type-safe wrappers, CI optimization.
