Andy Fingerhut contributed to the p4lang/p4c repository by developing and maintaining backend features, modernizing build and test infrastructure, and ensuring licensing compliance. He enhanced P4 action control flow handling and improved build reliability through targeted CMake configuration, using C++ and Python to refactor core components. Andy streamlined test data management and unified packet processing in the testing framework, reducing dependencies and improving CI stability. His work included upgrading CI pipelines, aligning licensing with open-source standards, and isolating flaky dependencies to maintain build health. These efforts resulted in a more robust, maintainable codebase and smoother onboarding for future contributors.
November 2025 — Focused on stabilizing the build for the p4c project by isolating flaky external dependencies. Key action: temporarily disable the p4lang-bmv2 Debian package to preserve build stability while issues are addressed. This prevented unstable builds and allowed continued progress on core development. No new user-facing features were released this month; stabilization and risk mitigation were the priority. All changes were reviewed and signed off appropriately.

March 2025: focused on testing stability, CI modernization, and license compliance for p4c/p4tc. Delivered PTF-based pcap handling in p4tc tests, upgraded CI to Ubuntu 22.04 across pipelines, and updated license metadata to GPL-2.0-only in ptf tests with Apache-2.0 fallback. These changes reduce test complexity, improve reliability, and align with current toolchains and licensing requirements.
