Jan 1, 2025January 2025 monthly work summary for rocicorp/mono: Delivered critical correctness and quality improvements across the ZQL execution path, enabled more flexible data consumption patterns, and upgraded tooling to raise code quality without sacrificing essential logging. Key bug fixes improved reliability and user-visible correctness, while a major refactor and tooling upgrade advanced performance and developer efficiency. Specifically, hydration errors in take operator now propagate correctly with tests added; whereExists now behaves correctly when preceded by where by ensuring filters are consistently applied in MemorySource and TableSource. A major refactor made ZQL node relationships callable, enabling multiple consumption, reduced redundant data fetching in Exist operator, and aligned ChildChange semantics with Node while ensuring drained nodes are properly cleaned up. ESLint config upgraded to 0.7.0 with controlled console usage to preserve necessary logs. Overall impact: lower runtime error rates, fewer debugging cycles, more predictable query results, and a stronger foundation for upcoming features.
