Worked on the supercollider/supercollider repository to address issues with the Bag class, focusing on preventing accidental mutations during in-place operations. Developed a robust deep copy method by implementing the Bag.copy API, ensuring that union and difference operations do not alter the original data structure. Utilized skills in class library development, data structures, and object-oriented programming with SC to resolve a shallow copy bug and improve code reliability. Added targeted tests, including TestBag.sc and test_bag_avoidsInPlaceOperation, to guard against regressions and verify non-mutating behavior. The work enhanced code quality and traceability through well-documented, focused changes and comprehensive testing.
July 2025 monthly summary for supercollider/supercollider: Implemented robust Bag.deep copy path and non-mutating bag operations to prevent accidental mutations. Introduced Bag.copy API and added targeted tests to guard union/difference behavior. Fixed shallow copy issue and ensured in-place Bag operations do not alter source. Changes are captured in commits 4e041def208731efc71adb5285d6122b090edca7 and 936ebb952d412184c23ba476d9769e55e2e7b827.
