Feb 1, 2025February 2025 focused on enhancing artifact metadata handling in the DiamondLightSource/workflows pipeline. Delivered MIME type exposure for artifacts by adding a mime_type accessor on the Artifact object, enabling more reliable routing and downstream decision-making based on content type. Implemented tests around MIME type exposure and updated dependencies to include mime_guess for robust MIME detection. A dedicated change set (Add MIME type field to artifact struct) lays the groundwork for improved data provenance and integration with external tools, with a commit reference recorded for traceability. No major bugs fixed this month; the work improves reliability, traceability, and business value of artifact handling in the workflow system.

Jan 1, 2025January 2025 (DiamondLightSource/workflows): Monthly summary focusing on delivering flexible status processing, safer data access patterns, and stronger test coverage to boost reliability and business value. Highlights include extensible status resolution, richer task data, and safer shared data handling, underpinned by targeted tests and documentation improvements. Key features delivered: - Graph proxy workflow status query tests: added tests for statuses 'failed', 'errored', 'running', and 'null' to validate status queries and edge cases. Commit coverage across four tests. - Workflow status resolver customization: introduced user-defined resolver functions for Running, Pending, and Complete to enable customizable business rules. - Task fetching and resolver enhancements: added user-defined Task resolver; removed intermediate Tasks enum for fetching missing data; moved missing task info fetching to a separate function for clarity and reuse. - Arc-based manifest storage: store top-level workflow manifest in an Arc to enable shared ownership and safer concurrency. - Tests for defaults and artifacts: added default limit handling test for multiple workflows query; introduced artifact struct and artifacts field to Task to support richer outputs. Major bugs fixed: - No explicit critical bugs reported in this period; focus was on reliability improvements, refactors, and test coverage to prevent regressions. Overall impact and accomplishments: - Substantially improved flexibility and reliability of workflow status processing with user-defined resolvers and safer data access patterns. - Reduced allocation overhead and improved data handling by moving fetch paths and using references where possible. - Enhanced concurrency safety through Arc-based manifest storage, supporting shared ownership across components. - Strengthened quality and maintainability via comprehensive tests, documentation improvements, and CI-friendly changes. Technologies/skills demonstrated: - Rust ownership and borrowing optimizations (use of references to avoid cloning). - Arc-based shared ownership and concurrency patterns. - Resolver pattern design enabling extensible status logic for workflows and tasks. - Test infrastructure enhancements and documentation hygiene (parameter schema annotations, test dir renaming).
