Herein, we propose an approach to check the equivalence of source code before and after refactoring using the AST-based model extracted from source code. In order to detect unintended changes to the program structure, our approach first transforms the model from the refactored code in accordance with the refactoring pattern so that the refactoring is cancelled, and then compares it with the model from the code before refactoring. We also built a tool named POM/EQ based on the Eclipse Modeling Framework for checking C/C++ source code. As a result of the case study using the tool, we successfully checked 56 % of the refactoring changes that are performed on an industrial product.","PeriodicalId":433677,"journal":{"name":"Proceedings of the 1st International Workshop on Software Refactoring","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130998138","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}

It is a key component of Agile methods, the most popular family of software development methodologies in industrial practice. Refactoring has also been the subject of much attention from researchers and many practitioner textbooks have been written on the topic. It would be natural to assume then that the benefits of refactoring would be easy agree upon, and easy to measure. In this position paper we review a selection of the empirical studies that have attempted to measure the benefits of refactoring and find the situation to be quite unclear. The evidence suggests that what motivates developers to refactor, and what benefits accrue from refactoring, are open issues that require further research.","PeriodicalId":433677,"journal":{"name":"Proceedings of the 1st International Workshop on Software Refactoring","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131661825","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}

However, existing approaches aimed at performance-driven refactoring of software models suffer from fragmentation across different paradigms, languages, and meta-models. This paper aims at reducing such fragmentation by exploiting the EPSILON environment, which provides a suite of languages for checking properties and applying refactoring on models. In particular, we introduce automation aimed at translating performance antipattern detection rules and refactoring actions among three EPSILON languages. Such automation helps to reduce code writing effort, in the context of performance-driven refactoring of UML models, while exploiting the specific support provided by the different execution semantics of considered languages.","PeriodicalId":433677,"journal":{"name":"Proceedings of the 1st International Workshop on Software Refactoring","volume":"329 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133433134","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}

OSS is generally developed by highly experienced developers who have multiple perspectives. However, previous studies have indicated that OSS has quality limitations in software maintainability. In general, OSS developers typically focus on achieving the correct functionality. In contrast, in addition to focusing on building software functionality, software engineering practices also focus on the structure of the software and on its maintainability. Code with a well-designed structure is more likely to result in high quality software. To better understand how peer code review can reduce ``code smells\" in existing OSS projects, we examined comments from code reviewers that identified code smells in OSS projects. This paper is a proof-of-concept that presents the preliminary results from an analysis of comments we obtained for two OSS projects, OpenStack and WikiMedia, both of which use the code review data repository called Gerrit. The preliminary results of this ongoing research show that code reviewers comment on only a small number of code smells. The full-scale results would contribute to the empirical body of validated knowledge in the field of OSS quality and code review.","PeriodicalId":433677,"journal":{"name":"Proceedings of the 1st International Workshop on Software Refactoring","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129237486","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}

Extract interface refactoring is a well known local refactoring which is commonly used in development tools. Beyond that local refactoring, there is a need for mass extraction of an interface hierarchy from a class hierarchy. In this paper, we made an experience with master students to put into practice an existing Formal Concept Analysis (FCA) based approach for solving that problem. The results show that the data selection (selected datatypes: interfaces, abstract classes, concrete classes; attributes; attribute description; methods; method description; etc.) was not obvious as it was expected to be, and that the students used the approach more as an analysis technique that would guide the extraction, than as a turn key solution.","PeriodicalId":433677,"journal":{"name":"Proceedings of the 1st International Workshop on Software Refactoring","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134016780","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}

Many of existing approaches are not correctly viable for detecting impure refactoring. To mitigate this problem, we propose an approach that detects impure refactoring from commits stored in the repositories using a graph search algorithm. In case study, we applied our approach to two actual classes in Apache Xerces project and confirmed the feasibility of the approach.","PeriodicalId":433677,"journal":{"name":"Proceedings of the 1st International Workshop on Software Refactoring","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131070930","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}
