Mar 1, 2026

Month: 2026-03 Concise monthly summary focused on key accomplishments and business value for ramsey/php-src. Key features delivered: - AIX Signal Handling Robustness: Implemented storage size promotion for num_signals to uint16_t to align with AIX NSIG behavior, preventing overflow and incorrect signal handler installation when using pcntl. This reduced runtime errors and improved resilience of signal-related tooling on AIX. - POSIX Spawn Compatibility Improvement: Replaced deprecated _np variant with non-deprecated posix_spawn_file_actions_addchdir where available, improving compatibility on macOS and other POSIX-heavy environments and reducing future deprecation warnings. - Build System Stabilization and Cross-Platform Compatibility: Updated bundled libtool to 2.5.4 to fix build race conditions in parallel builds and enhance macOS/NixOS compatibility, increasing reliability of releases across platforms. Major bugs fixed: - pcntl signal handling overflow on AIX (addressed by widening storage, preventing crashes and ValueError during signal installation). Overall impact and accomplishments: - Increased cross-platform stability for PHP builds and runtime behavior across AIX, macOS, and NixOS. - Reduced build failures and packaging friction, enabling smoother releases and faster iteration. - Clear improvements in developer experience due to mitigated platform-specific edge cases and clearer signaling behavior in critical tooling. technologies/skills demonstrated: - C-level signal handling and PCNTL, AIX-specific considerations - Libtool and autotools build system maintenance - POSIX spawn API usage and deprecation awareness - Cross-platform testing mindset and release engineering
