November 2025 (Month: 2025-11) - Developer monthly summary for numpy/numpy focusing on SWIG wrapper compatibility and unit testing enhancements. Key features delivered: - SWIG wrapper compatibility fix for SWIG 4.4: Adjusted the return statement in the import_array macro to prevent build failures with newer SWIG versions; enhanced CI by integrating SWIG unit tests and addressing tensor type handling in tests. Major bugs fixed: - Fixed compilation error of the wrapper file generated with SWIG >= 4.4 by returning NULL or 0 depending on SWIG version, ensuring compatibility across versions; closes: numpy/numpy#30122. - CI/test updates: replaced deprecated unittest usage and fixed tensor-related test expectations to align with newer SWIG bindings; ensured SWIG binding tests run after sdist installation. Overall impact and accomplishments: - Increased build stability and compatibility with newer SWIG versions, reducing breakage risk for users and contributors. - Strengthened testing coverage for Python-C/C++ bindings, leading to faster feedback, fewer regressions, and smoother releases. - Improved CI reliability for SWIG-related workflows, enabling more robust validation of bindings before merge. Technologies/skills demonstrated: - C/C++, SWIG, Python, unit testing, CI automation, cross-language binding debugging, test design and maintenance.
