研究方向
This issue tracks fuzzing of several TiKV coprocessor and util modules. Many sub tasks are unchecked, such as coprocessor::codec::mysql::json::binary. To get started, examine completed fuzz targets (e.g., linked PRs for decimal, duration) for structure and patterns. Focus on a single unchecked module, writing fuzz harnesses using existing infrastructure. The issue body contains explicit file paths and uncovered bugs for reference.
