October 2025 MXCuBE-Web performance and stability sprint. Delivered release-ready changes, modularized components, and strengthened logging and error handling across MXCuBE-Web and MXCuBE-Core to enable faster releases and more reliable operation in production. Key features delivered: - Version bumps and release prep across mxcubeweb and related components to align minor-versioning and support a smooth minor release. - Moved sample-list functionality to the LIMS component to improve modularity and reduce cross-component coupling. - Migrated sample-changer signal handling to the dedicated sample-changer component for clearer responsibilities. - Converted the LIMS component to a full MXCuBE-Web component and moved the sample changer component to the adapter layer. - API and helper improvements (e.g., get_sc_contents_as_dict) to access contents as a dictionary. - Renamed session API (get_full_path to get_full_paths) to align with updated design. - Shortcuts handling made more robust for runtime stability. - Version bump consolidation and minor-release preparations across mxcubeweb and mxcubecore. Major bugs fixed: - Exception logger enhancement: replaced pass statements and added explicit exception logging to ensure errors are captured in logs. - Logger refactor to use class-level logger (self.log) for consistent logging behavior. - Error logging improvement: replaced traceback.print_exc with logger.exception to improve visibility and traceability of errors. Overall impact and accomplishments: - Improved maintainability through clearer component boundaries and standardized logging. - Faster release cycles with consolidated version management and release prep. - Better observability and diagnosability via enhanced error handling and class-based logging. - Reduced risk of regressions through targeted refactors and modularization (LIMS, adapter, and SampleChanger components). Technologies/skills demonstrated: - Python-based MXCuBE-Web architecture, HardwareObject patterns, and Adapter design. - Modularization and componentization of complex software (LIMS, SampleChanger, Adapter layers). - Robust logging practices (class-based log, logger.exception) and improved error reporting. - Version management and release engineering for multi-repo projects.
