Code Clone Tracer (CCT): A Tracking Tool for Analyzing Human and Social Factors in Creating and Reusing Code Clones
Yusuke Kukita, Kojiro Noguchi, Masao Ohira · 2019
This paper introduces a tool called CCT (Code Clone Tracer) which is designed to help practitioners and researchers analyze the impacts of human/social factors on software quality in creating and reusing code clones. CCT tracks a history of created and reused code clones for all the revisions in a distributed version control system such as Git. The tool also has features to analyze the relationship between bug-inducing changes and developers, working together with a bug tracking system such as Bugzilla and JIRA. This paper reports our pilot case study where CCT is applied to three open source projects (RxJava, c:geo, and Jackson databind). The results of the case study indicated that a small number of particular developers were involved in many of clone changes to resolve issues.
