- Abstract
Copying code fragments and then reusing those by pasting with or without modifications or adaptations are common activities in software development. This type of reuse approach of existing code is called code cloning and the pasted code fragment is called a clone of the original. Several studies show that about 5% to 20% of software systems can contain duplicated code, causing modification of all the fragments if a bug is detected in one code fragment. Although being a prime issue in software maintenance, refactoring of certain clones are not desirable and there is a risk of removing those. However, it is also widely agreed that clones should at least be detected and monitored across successive versions. Clone Region Descriptor (CRD) is an existing way for monitoring clones in evolving software systems. However, it has robustness issues for changes in code nesting level and block matcher parts called as anchors. This research works with overcoming these limitations by improving the CRDs through making those more abstract and adding more metrics for resolving block matching conflicts. The justification of the new approach is done by showing two case studies on the two proposed improvements.
