Worked on enhancing vacuum reliability in the tursodatabase/turso repository by expanding test coverage and improving code clarity. Focused on verifying that the vacuum operation effectively compacts fragmented data, which helps maintain data integrity and reduces storage footprint. Refactored existing tests to improve SQL command formatting and error messages, making the test suite easier to maintain and understand. Addressed Clippy lint issues to uphold code quality and minimize continuous integration noise. Utilized Rust and SQL for database management and testing, enabling safer future changes and faster regression detection. The work laid a foundation for more robust and maintainable database operations.
