Worked on enhancing the reliability of log synchronization in the Tencent/WeKnora repository by focusing on the GetSyncLogs API endpoint. Addressed a critical bug by enforcing strict validation of the limit parameter, ensuring that only valid inputs are processed and reducing the risk of downstream errors. Implemented robust error handling to gracefully manage invalid requests, and expanded test coverage to include both validation and error scenarios, thereby preventing regressions. Utilized Go for backend and API development, with a strong emphasis on testing practices. These improvements contributed to greater data integrity and increased developer confidence in the synchronization workflow.
