April 2026 monthly summary for trinodb/trino focused on security hardening and correctness in column-level permissions for SQL Server. Delivered a robust fix to determine case sensitivity by reading column names and collations from the system catalog, replacing a failing permission-check path with a reliable query. Added tests ensuring users can access permitted columns and are denied access to restricted ones. This work decreases risk of unintended data exposure and improves cross-connection consistency for SQL Server permissions.

Month: 2026-03 — Focused on strengthening test reliability for the trinodb/trino project by implementing a robust test-table naming strategy for SQL Server and validating it through CI. Key outcomes include reduced flaky test failures, clearer test artifacts, and a foundation for scalable test parallelism. No major bugs were reported this month; efforts centered on feature delivery and test infrastructure resilience. Overall impact: more reliable CI runs, faster feedback, and improved stability for SQL Server tests. Technologies and skills demonstrated include test automation, naming strategies, concurrency handling, and CI integration with commit-based delivery.
