Worked on the Easya-Solutions/dolibarr repository to enhance the logging subsystem by implementing robust handling of invalid log levels within the dol_syslog path. The approach involved replacing the previous getDolGlobalInt() dependency with direct log level assignment in PHP, streamlining the codebase and reducing maintenance complexity. Error handling was improved by introducing a fallback to a default log level and adding localized error messages through a new translation key, supporting internationalization and consistent user experience across locales. The work was delivered as a focused, atomic set of backend development commits, prioritizing reliability, maintainability, and clear incident diagnosis for future deployments.
