Worked on stabilizing binary log processing in the MariaDB/server repository, focusing on a regression fix for multi-file handling when the --stop-datetime option is used. Addressed an issue where mariadb-binlog could not process more than one log file under these conditions by implementing last-processed-event timestamp tracking and introducing a warning if the stop-datetime is not reached after all eligible files are processed. This solution, developed in C++ and leveraging skills in database administration and regression testing, improved the reliability and correctness of time-based binlog stopping, ensuring more predictable and accurate outcomes for users relying on stop-datetime semantics.
