May 1, 2025

May 2025 monthly summary for dbos-inc/dbos-transact-ts and dbos-inc/dbos-docs. Key work focused on workflow management improvements, stability, and developer experience across two repos. Major features delivered include: (1) Workflow Inspection/Management API overhaul with a newly exposed listWorkflowSteps to retrieve executed steps and improved workflow status handling, (2) Workflow timeout support with configurable initiation/execution timeouts and enforcement via Promise.race, (3) DBOS core stability and API surface cleanup to reduce duplication, privatize internal components, and clarify migration paths, and (4) Documentation enhancements for workflow management in DBOS Client/TS and related workflows, plus removal of experimental time travel docs to reflect current capabilities. Major bug fix: transaction recovery error handling fix to avoid re-recording a previously found error result, with additional tests. Business impact: greater visibility and control over long-running workflows, deterministic timeouts reducing operational stalls, reduced risk of duplicate error recordings, and a cleaner, more maintainable API surface which accelerates integration and onboarding for developers and teams relying on DBOS workflows. Technologies/skills demonstrated: TypeScript API design and refactoring, Promise-based timeout enforcement, robust error handling and testing in recovery flows, documentation craftsmanship for developer experience, and ongoing emphasis on code quality, migration guidance, and API surface clarity.

January 2025

3 Commits • 1 Features

Jan 1, 2025

January 2025 focused on improving developer onboarding and runtime reliability across dbos-docs and dbos-transact-py. Key features delivered: comprehensive documentation for asynchronous Python workflows, detailing async API usage (send_async, recv_async, set_event_async, get_event_async, sleep_async) and guidance on using coroutines as DBOS steps, including the transaction limitation. Major bugs fixed: PostgreSQL parameter placeholder syntax corrected in the tutorial sample code (replacing ? with $1, $2); introduced NoResult singleton in Outcome.intercept to distinguish no cached result from cached None, improving caching accuracy. Overall impact: higher developer productivity, more reliable tutorials, and stronger caching behavior, contributing to platform stability and reduced support needs. Technologies demonstrated: PostgreSQL parameter formatting, asynchronous Python patterns, singleton design for caching, and emphasis on maintainable documentation.
