PROFILE

Peter Kokot

Peter Kokot focused on modernizing and stabilizing build systems across major open-source repositories such as php/php-src, ramsey/php-src, and curl/curl. He delivered robust improvements by refactoring Autotools and CMake configurations, consolidating headers, and removing deprecated macros to ensure cross-platform compatibility and reduce build failures. Using C, Autoconf, and Shell scripting, Peter addressed environment-specific issues, enhanced CI reliability, and simplified extension integration. His work included enabling default image format support, improving Windows compatibility, and optimizing performance for different architectures. These contributions resulted in cleaner, more maintainable codebases and predictable build processes, lowering maintenance costs and supporting future development.

Sep 1, 2025

September 2025 monthly summary for php/php-src: Delivered a targeted config header cleanup that reduces macro handling risk and simplifies headers. Completed a follow-up to GH-15630 by removing redundant #undef directives for HAVE_ADABAS and HAVE_SOLID in config.w32.h.in. This work improves build reliability on Windows and eases future maintenance.

Jun 1, 2025

June 2025 focused on strengthening build reliability, cross-platform consistency, and performance stability for ramsey/php-src. Key work included consolidating and modernizing the build system across PHP extensions, removing deprecated configuration paths, and enabling architecture-aware performance optimizations. These changes reduce misconfigurations, simplify onboarding for contributors, and ensure consistent behavior across Windows and non-Windows platforms. The month delivered tangible, business-facing improvements in developer productivity, toolchain cleanliness, and runtime performance. Overall impact: a cleaner, standards-aligned codebase with a more predictable build and deployment process, lowering maintenance cost and risk while preparing the project for future extension work. Technologies and skills demonstrated: Autotools modernization, configuration header consolidation (php_config.h), Windows build flag cleanup, deprecated macro/INI directive removal, and cross-architecture performance tuning (big-endian) for TSRM hash extensions.

May 1, 2025

Month: 2025-05 — Focused on stabilizing the LDAP extension build for ramsey/php-src through Autotools. Delivered a robust fix for building the LDAP extension as a shared library and when using non-standard LDAP installation paths by refactoring include directory and library flag handling. Implemented in commit 25e8aa5cd22d5d461a5db247cfaedbba6e85e566 with the subject 'Autotools: Fix ext/ldap shared build (#18673)'. This work reduces environment-specific build failures, improves CI reliability, and simplifies integration for downstream projects.
