Feb 1, 2025

February 2025 monthly summary for uc-cdis/gen3sdk-python: Focused on enabling more flexible file retrieval, improving reliability of tests and CI, and keeping dependencies current. Delivered a feature to make external_oidc_idp optional and rely on file_retriever as the primary field to enable non-token workflows, with a complementary regression fix reinstating explicit requirements to ensure robust token retrieval when needed. Updated Dataverse retriever tests to reflect current behavior, and hardened CI workflows with GitHub Actions version bumps and secret handling, while aligning dependencies (Poetry/Gen3) to recent minor versions. Also performed documentation build cleanup and restoration to ensure consistent docs output. These changes collectively reduce integration risk, improve data retrieval reliability, speed up release cycles, and deliver greater flexibility for clients using non-token authentication flows. Technologies/skills demonstrated include Python, Poetry, GitHub Actions, and robust testing practices.
