Abstract

The process and activities of software development are very dynamic and diverse. For instance, source code has to be written, tested and revised, e-mails have to be sent, bugs have to be communicated, managed and fixed. As a consequence, the contributions of the developers are very diversified. This paper describes an empirical study whose goal was to assess and compare the contributions of the developers through software repository mining. Two medium-sized projects -- an open source and a commercial project -- were analyzed. Overall, 17,490 commits and 10,308 bugs reports were analyzed. In the first part of our study, we have classified the developers based on their contribution to the software repository in three groups -- core, active and peripheral developers. After that, we have collected a series of metrics -- code contribution, buggy commits and resolution of priority bugs -- for all the developers of the investigated projects. Finally, we have analyzed the collected metrics for the different developer groups. Our study findings show significant differences in the contribution provided by the developers groups considering the open-source and the commercial project.

揭示代码提交背后的开发人员贡献:一项探索性研究

软件开发的过程和活动是非常动态和多样化的。例如，必须编写、测试和修改源代码，必须发送电子邮件，必须沟通、管理和修复错误。因此，开发者的贡献是非常多样化的。本文描述了一项实证研究，其目的是通过软件存储库挖掘来评估和比较开发人员的贡献。我们分析了两个中等规模的项目——一个开源项目和一个商业项目。总共分析了17,490个提交和10,308个bug报告。在我们研究的第一部分中，我们根据开发人员对软件存储库的贡献将他们分为三组——核心开发人员、活跃开发人员和外围开发人员。之后，我们收集了一系列指标——代码贡献、错误提交和优先级错误的解决——用于所有被调查项目的开发人员。最后，我们分析了针对不同开发团队收集的指标。我们的研究结果表明，考虑到开源项目和商业项目，开发团队提供的贡献存在显著差异。
