July 2026 highlights for tursodatabase/turso: Implemented two major robustness fixes with regression tests, improving stability for large-scale queries and complex expressions. Key outcomes: - Overflow-safe fix in op_sorter_open for negative cache_size including i32::MIN; added regression test for ORDER BY; prevents ORDER BY panics when cache_size is at its minimum and ensures safe behavior across 32-bit targets. Commit d79eadfc480c65ecc9964336990ac8321a98003e. Fixes #7150. - Parser hardening: enforced a fixed expression-depth limit to prevent translator stack overflow; included comprehensive regression tests covering deeply nested and wide expression trees; commit 8011555c64449e962fb6ad6b33f61325a7d729d2. Fixes #5071. - Broader test coverage: added integration and Turso-specific conformance tests to validate stability under extreme inputs and across wasm32/other targets; strengthened CI guardrails against regressions in edge-case scenarios. Overall impact: - Increased reliability for customers with large datasets and complex queries, reducing runtime panics and parser-related outages. - Clearer safety boundaries in core components (sorter initialization and parser depth) leading to more maintainable, predictable performance. Technologies/skills demonstrated: - Rust safety practices (unsigned_abs, saturating_mul), robust error handling, and regression-testing discipline. - Regression/integration testing, fuzz guardrails, and cross-platform validation (including 32-bit targets/wasm32). - Issue-driven development with explicit tracking (fixes #7150, #5071).
