Luke Sy

Luke developed the Bag File Circular Logging with Retention Limit feature for the ros2/rosbag2 repository, addressing disk-space management for log data. He implemented automatic pruning of the oldest bag files when a configurable limit is reached, exposing retention controls through YAML, Python bindings, and the CLI. Using C++ and Python, Luke unified retention configuration, removed obsolete options, and improved error handling to prevent filesystem hangs. He expanded integration tests to verify real-disk deletion and metadata updates, ensuring robust end-to-end behavior. This work delivered predictable disk usage, improved storage reliability, and streamlined configuration for users managing large-scale logging workflows.

February 2026 highlights the delivery of Bag File Circular Logging with Retention Limit for rosbag2, delivering reliable disk-space management for log data. The feature introduces automatic pruning of the oldest bag files when a configured limit is reached, with storage retention exposed via YAML/params, Python bindings, and a CLI option. The initiative includes a robust integration test suite that verifies real-disk behavior (sqlite3/mcap), ensuring that files are actually removed when max_bag_files is exceeded. In addition to the feature, several quality improvements and refactors were completed: - Consolidated retention controls under max_bag_files (renaming from max_splits to max_bag_files) across CLI, C++, Python, YAML, and ROS params for clarity. - Removed obsolete options (max_record_size and max_record_duration) to simplify storage configuration and reduce surface area. - Fixed major edge cases around deletion: updated per-file per-topic metadata counts, adjusted message counts on deletion, and added graceful error handling for filesystem operations to avoid infinite loops. - Expanded test coverage with integration tests for max_bag_files deletion and file-extension checks, validating end-to-end behavior on real storage backends. - Demonstrated end-to-end business value with predictable disk usage, improved storage reliability, and clearer configuration paths for users and operators.
