CloneWorks: A Fast and Flexible Large-Scale Near-Miss Clone Detection Tool

摘要

Clone detection within large inter-project source-code repositories has numerous rich applications. CloneWorks is a fast and flexible clone detector for large-scale near-miss clone detection experiments. CloneWorks gives the user full control over the processing of the source code before clone detection, enabling the user to target any clone type or perform custom clone detection experiments. Scalable clone detection is achieved, even on commodity hardware, using our partitioned partial indexes approach. CloneWorks scales to 250MLOC in just four hours on an average workstation with good recall and precision.
