SUMMARYThere are many software systems that have been used and maintained for a long time. By undergoing such a maintenance process, similar code fragments were intentionally left in the source code of such software, and knowing how to manage a software system that contains a lot of similar code fragments becomes a major concern. In this study, we proposed a method to pick up components that were commonly used in similar code fragments from a target software system. This method was realized by using the component rank model and by checking the differences of evaluation values for each component before and after merging components that had similar code fragments. In many cases, components whose evaluation value had decreased would be used by both the components that were merged, so we considered that these components were commonly used in similar code fragments. Based on the proposed approach, we implemented a system to calculate differences of evaluation values for each component, and conducted three evaluation experiments to confirm that our method was useful for detecting components that were commonly used in similar code fragments, and to confirm how our method can help developers when developers add similar components. Based on the experimental results, we also discuss some improvement methods and provide the results from applications of these methods.

Abstract-Programmers tend to write code clones unintentionally even in the case that they can easily avoid them. Clone change management is one of crucial issues in open source software (OSS) development as well as in industrial software development (e.g., development of social infrastructure, financial system, and medical equipment). When an industrial developer fixes a defect, he/she has to find the code clones corresponding to the code fragment including it. So far, several studies performed on the analysis of clone evolution in OSS. However, to our knowledge, a few researches have been reported on an application of a clone change notification system to industrial development process. In this paper, we introduce a system for notifying creation and change of code clones, and then report on the experience with 40-days application of it into a development process in NEC Corporation. In the industrial application, a developer successfully identified ten unintentionally-developed clones that should be refactored.

“…Nguyen et al [20] presented a novel clone management tool called JSync, which provides supports for developers in being aware of the clone relation among code fragments and in making consistent changes as they create or modify cloned code. Yamanaka et al [21] proposed a clone change management system, which can categorize code clones based on their evolution patterns and report changed information through a web-based UI and e-mail notification.…”

Effective clone management is essential for developers to recognize the introduction and evolution of code clones, to judge their impact on software quality, and to take appropriate measures if required. Our previous study shows that cloning practice is not simply a technical issue. It must be interpreted and considered in a larger context from technical, personal, and organizational perspectives. In this paper, we propose a contextual and on-demand code clone management approach called CCEvents (Code Cloning Events). Our approach provides timely notification about relevant code cloning events for different stakeholders through continuous monitoring of code repositories. It supports on-demand customization of clone monitoring strategies in specific technical, personal, and organizational contexts using a domain-specific language. We implemented the proposed approach and conducted an empirical study with an industrial project. The results confirm the requirements for contextual and on-demand code clone management and show the effectiveness of CCEvents in providing timely code cloning notifications and in helping to achieve effective clone management.
