Nov 1, 2024November 2024 (2024-11) – adap/flower: Delivered a focused set of feature enhancements, robustness improvements, and developer tooling that increase reliability, multi-run readiness, and business value. Highlights include API/state improvements, user-facing tooling, and observability enhancements, paired with targeted bug fixes to reduce runtime risk and improve deployment confidence. Key features delivered: - Code cleanup and API improvements: Removed unused internal function _has_field, reducing technical debt and surface area for future changes. - State and API enhancements: Added get_run_ids to LinkState to improve run management and introspection; validated node IDs for TaskIns in LinkState.store_task_ins to prevent invalid state transitions. - User-facing tooling and CLI: Added --flwr-dir option to flower-superlink to streamline deployment and maintenance workflows; introduced flwr ls command and ExecServicer.ListRuns RPC to improve run discovery and operational visibility. - Telemetry and run model enhancements: Exposed run-related context with date utilities and Run timestamps/status to improve monitoring and auditability. Major bugs fixed: - Import management and module reload stability: Improved import handling in load_app and reloading behavior when the project directory hasn’t changed, reducing hot-reload issues during development. - Multi-run and API correctness fixes: Allow flwr-serverapp to join multiple runs; fix usage of FfsFactory in rest_api.py to ensure correct REST API factory behavior. - Server reliability and observability: Improved server-side logging, and removed TLS-specific behavior from flwr-serverapp and related log-upload flows to simplify deployments. - Versioning and dependency stability: Updated changelog and version pins to reflect 1.14.0 readiness with Unreleased hygiene and install-related cleanup. Overall impact and accomplishments: - Increased reliability for multi-run workflows and clearer run visibility with new CLI/RPC surfaces, enabling faster diagnosis and smoother deployments. - Reduced operational risk through targeted fixes in import handling, module reload, and server observability. - Strengthened developer experience with API enhancements and improved tooling, supporting faster feature delivery and iteration. Technologies/skills demonstrated: - Python refactoring and API design; state management and validation; CLI tooling and RPC design; dependency management and retry improvements; enhanced observability and logging; deployment tooling refinements.
