Do time of day and developer experience affect commit bugginess
Modern software is often developed over many years with hundreds of thousands of commits. Commit metadata is a rich source of social characteristics, including the commit’s time of day and the experience and commit frequency of its author. The “bugginess” of a commit is also a critical property of that commit. In this paper, we investigate the correlation between a commit’s social characteristics and its “bugginess”; such results can be very useful for software developers and software engineering researchers. For instance, developers or code reviewers might be well-advised to thoroughly verify commits that are more likely to be buggy. In this paper, we study the correlation between a commit’s bugginess and the time of day of the commit, the day of week of the commit, and the experience and commit frequency of the commit authors.
