Description

Title:Automated Detection of Refactorings in Evolving Components
Author(s):Dig, Danny; Comertoglu, Can; Marinov, Darko; Johnson, Ralph
Subject(s):computer science
Abstract:One of the costs of reusing software components is migrating applications to use the new version of the components. Migrating an application can be error-prone, tedious, and disruptive of the development process. Our previous work shows that more than 80% of the disruptive changes in four different components were caused by refactorings. If the refactorings that happened between two versions of a component could be automatically detected, a refactoring tool could replay them on applications. We present an algorithm that detects refactorings performed during component evolution. Our algorithm uses a combination of a fast syntactic analysis to detect refactoring candidates and a more expensive semantic analysis to refine the results. The experiments on codebases ranging from 17 KLOC to 350 KLOC show that our algorithm detects refactorings in real-world components with accuracy over 85%.
