Abstract

Refactoring is a critical task in software maintenance and is usually performed to enforce best design practices, or to cope with design defects. Previous studies heavily rely on defining a set of keywords to identify refactoring commits from a list of general commits extracted from a small set of software
systems. All approaches thus far consider all commits without checking whether refactorings had actually happened or not. In this paper, we aim at exploring how developers document their refactoring activities during the software life cycle. We call such activity Self-Affirmed Refactoring, which is an indication of
the developer-related refactoring events in the commit messages. Our approach relies on text mining refactoring-related change messages and identifying refactoring patterns by only considering
refactoring commits. We found that (1) developers use a variety of patterns to purposefully target refactoring-related activities; (2) developers tend to explicitly mention the improvement of specific quality attributes and code smells; and (3) commit messages with
self-affirmed refactoring patterns tend to have more significant refactoring activity
