Month 2025-09 – RS-PYTHON/rs-client-libraries: Reliability improvement for wait_for_job. Removed client-side timeout due to missing cancel_job endpoint in rs-server staging, replacing a potentially erroneous finite timeout with an infinite wait that waits for staging to complete (success or failure). This aligns client behavior with server capabilities, reducing false timeouts and unnecessary retries, and stabilizing deployment workflows.

March 2025 monthly summary for RS-PYTHON repositories. Delivered key features and reliability improvements in rs-server and rs-client-libraries, with a focus on CI readiness, distributed task coordination, and clear documentation. Highlights include reorganizing diagram ownership by moving python-rs-client.plantuml to rs-client, implementing robust Dask token handling with a new token-info lock and timestamped logs, and refactoring the station token refreshment flow to use local locks/lists for safer parallel execution. Also improved documentation quality and CI stability through warnings/docstring fixes, __init__.py for module imports, and SonarQube/pylint/test fixes. Additional notebook debugging support and RS Client architecture documentation updates completed.

February 2025 performance snapshot: Key features and improvements delivered across RS-PYTHON/rs-client-libraries and RS-PYTHON/rs-server. In rs-client-libraries, the STAC Client Core Refactor and Unified API consolidated STAC clients under a common base (StacBase), standardized service URL handling (href_srv), centralized error handling, and streamlined initialization across Auxip/Cadip/Stac. This work is reflected in commits such as f4870f34..., 942014b8..., e9743e8..., 268ca780..., 0ff95efd..., and f136f209...; and added targeted item retrieval enhancements to get_items (f70d4c68..., c7c0558c...). Dependency and test infrastructure updates include upgrades and lockfile synchronization (4195c704..., 958fc849..., b0c4d7a5..., 91732052). In rs-server, observability improvements were achieved by enhancing logs with collection name and full query parameters and by trimming extraneous content from openapi.json in tests (f2dc5928..., eab0cf6a...). Overall, these changes improve maintainability, data access efficiency, observability, and test reliability.
