Real-World Clone-Detection in Go

In the early stage of development, developers copied internal code snippets to enhance developing efficiency. With the rapid growth of Bytedance, similar or equivalent code snip-pets across different repositories or different product lines' codebases would potentially increase the cost of maintenance and distribute vulnerable code snippets. With the application of Clone-Detection, there are multiple well-established tools or techniques used for detecting similar code snippets in Java, JavaScript, Objective C and etc [1], [3]. We could hardly find similar tools available for Go, a widely-used programming language in the field of server development, especially at Bytedance. For the lack of public and labeled datasets, we utilized a great number of code snippets in Bytedance's codebase and trained an unsupervised model to propose Go-CopyCatch (GoCC), a tool and technique for Clone-Detection in Go.
