Classifying Change Types for Qualifying Change Couplings
Current change history analysis approaches rely on information provided by versioning systems such as CVS. Therefore, changes are not related to particular source code entities such as classes or methods but rather to text lines added and/or removed. For analyzing whether some change coupling between source code entities is significant or only minor textual adjustments have been checked in, it is essential to reflect the changes to the source code entities. We have developed an approach for analyzing and classifying change types based on code revisions. We can differentiate between several types of changes on the method or class level and assess their significance in terms of the impact of the change types on other source code entities and whether a change may be functionality-modifying or functionality-preserving. We applied our change taxonomy to a case study and found out that in many cases large numbers of lines added and/or deleted are not accompanied by significant changes b...
