| Outline of Final Research Achievements |
In this research study, we improved a tool that automatically records fine-grained edit operations during the construction of a program and proposed two methods that can support future maintenance of the program. One of the methods implements automatic detection of program changes based on programmers’ policies with respect to aggregation of recorded edit operations. The other method slices the edit operation history and replays its resulting slices, using a graph that represents the dependencies among edit operations in the history. We also developed powerful tools that implement the respective methods and demonstrated their usefulness for supporting program evolution.
