It enables decision-making about software systems being changed or being prepared for change. While scientific literature on architecture evaluation approaches is available, publications on practical experiences are rather limited. In this paper, we share our experiences - after having performed more than 50 architecture evaluations for industrial customers in the last decade. We compiled facts and consolidate our findings about the risk of software change and architecture evaluations as a means to mitigate change. We highlight the role of reverse engineering in these projects. In addition, we share our lessons learned and provide data on common beliefs and provide examples for frequently observed misconceptions on the power of reverse engineering. This industrial and practical perspective allows practitioners to benefit from our experience in their daily architecture work and the scientific community to focus their research work on the generalizability of our findings.","PeriodicalId":166271,"journal":{"name":"2014 Software Evolution Week - IEEE Conference on Software Maintenance, Reengineering, and Reverse Engineering (CSMR-WCRE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128555030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the past, several techniques have been developed for the detection and management of software clones. Existing code duplication can be eliminated by extracting the common functionality into a single module. However, the unification and refactoring of software clones is a challenging problem, since clones usually go through several modifications after their initial introduction. In this paper we present an approach for the unification and refactoring of software clones that overcomes the limitations of previous approaches. More specifically, our approach is able to detect and parameterize non-trivial differences between the clones. Moreover, it can find an optimal mapping between the statements of the clones that minimizes the number of differences. We compared the proposed technique with a competitive clone refactoring tool and concluded that our approach is able to find a significantly larger number of refactorable clones.","PeriodicalId":166271,"journal":{"name":"2014 Software Evolution Week - IEEE Conference on Software Maintenance, Reengineering, and Reverse Engineering (CSMR-WCRE)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134467006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we analyze a number of `little software systems' readily implementing a common feature set. We analyze source code, structured documentation, derived metadata, and other computed data. More specifically, we compare these systems on the grounds of the NCLOC metric while delegating more advanced metrics to future work. To reason about feature implementations in such a multi-language and multi-technological setup, we rely on an infrastructure which enriches traditional software artifacts (i.e., files in a repository) with additional metadata for implemented features as well as used languages and technologies. All resources are organized and exposed according to Linked Data principles so that they are conveniently explorable; both programmatic and interactive access is possible. The relevant formats and the underlying ontology are openly accessible and documented.","PeriodicalId":166271,"journal":{"name":"2014 Software Evolution Week - IEEE Conference on Software Maintenance, Reengineering, and Reverse Engineering (CSMR-WCRE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130575526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mining software repositories (MSR) field studies the valuable data available in software repositories such as source code version-control systems, issue/bug-tracking systems, or communication archives. In recent years, many researchers have used MSR techniques as a way to support software understanding and evolution. While many software systems are data-intensive, i.e., their central artefact is a database, little attention has been devoted to the analysis of this important system component in the context of software evolution. The goal of our work is to reduce this gap by considering the database evolution history as an additional information source to aid software evolution. We present DAHLIA (Database ScHema EvoLutIon Analysis), a visual analyzer of database schema evolution. Our tool mines the database schema evolution history from the software repository and allows its interactive, visual analysis. We describe DAHLIA and present our novel approach supporting data-intensive software evolution.","PeriodicalId":166271,"journal":{"name":"2014 Software Evolution Week - IEEE Conference on Software Maintenance, Reengineering, and Reverse Engineering (CSMR-WCRE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123988693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although developers often use return null to indicate that a program does not satisfy some necessary conditions, it is generally felt that a method returning null is costly to maintain. One of the reasons for is that when a method receives a value returned from a method invocation whose code includes return null, it is necessary to check whether the returned value is null or not (null check). As developers often forget to write null checks, null dereferences occur frequently. However, it has not been clarified to what degree return null affects software maintenance during software evolution. This paper shows the influences of return null by investigating return null and null check in the evolution of source code. Experiments conducted on 14 open source projects showed that developers modify return null more frequently than return statements that do not include null. This result indicates that return null has a negative effect on software maintenance. It was also found that the size and the development phases of projects have no effect on the frequency of modifications on return null and null check. In addition, we found that all the projects in this experiment had from one to four null checks per 100 lines.","PeriodicalId":166271,"journal":{"name":"2014 Software Evolution Week - IEEE Conference on Software Maintenance, Reengineering, and Reverse Engineering (CSMR-WCRE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129481647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
