However, this search is usually performed manually and relies heavily on developers. In this paper, we propose a feature location approach that, instead of searching directly into code from a natural language query as other approaches do, transforms a natural language query to a query that is made up of the requirements that are located as relevant. Furthermore, our approach limits the scope of the code search space by selecting only the code of those products that hold relevant requirements. We evaluate the overall effectiveness of our approach in the industrial domain of train control software. Our results show that our approach improves in 18.1% the results of precision with regard to searching directly into code, which encourages further research in this direction.","PeriodicalId":128559,"journal":{"name":"Proceedings of the 20th International Systems and Software Product Line Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134563833","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}

Software Product Lines (SPL) engineering is increasingly being applied to handle variability in industrial software systems. Problem. The research community has pointed out a series of benefits which modularity brings to software composition, a key aspect in SPL engineering. However, in practice, the reuse in Javascript-based systems relies on the use of package managers (e.g., npm, jam, bower, requireJS), but these approaches do not allow the management of project features. Method. This paper presents the RiPLE-HC, a strategy aimed at blending compositional and annotative approaches to implement variability in Javascript-based systems. Results. We applied the approach in an industrial environment and conducted an academic case study with six open-source systems to evaluate its robustness and scalability. Additionally, we carried a controlled experiment to analyze the impact of the RiPLE-HC code organization on the feature location maintenance tasks. Conclusion. The empirical evaluations yielded evidence of reduced effort in feature location, and positive benefits when introducing systematic reuse aspects in Javascript-based systems.","PeriodicalId":128559,"journal":{"name":"Proceedings of the 20th International Systems and Software Product Line Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133087060","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 produce products with purposefully different quality attributes, several challenges must be addressed. First, one must be able to distinguish product quality attributes to the customers in a meaningful way. Second, one must create the desired quality attribute differences during product-line architecture design and derivation. To study how performance is varied purposefully in software product lines, we conducted a comparison and re-analysis of two industrial case studies in the telecommunication and mobile game domains. The results show that performance variants must be communicated to the customer in a way that links to customer value and her role. When performance or its adaptation are crucial for the customer, performance differences must be explicitly \"designed in\" with software or hardware means. Due to the emergent nature of performance, it is important to test performance and manage how other variability affects performance.","PeriodicalId":128559,"journal":{"name":"Proceedings of the 20th International Systems and Software Product Line Conference","volume":"517 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123101345","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 refactoring and conservative extension scenarios, we can avoid this problem by checking for behavior preservation, either by testing the generated products or by using formal theories. Product line refinement theories support that by requiring behavior preservation for all existing products. However, in many evolution scenarios, such as bug fixing, there is a high chance that only some of the products are refined. To support developers in these and other non full-refinement situations, we define a theory of partial product line refinement that helps to precisely understand which products should not be affected by an evolution scenario. This provides a kind of impact analysis that could, for example, reduce test effort, since products not affected do not need to be tested. Additionally, we formally derive a catalog of eight partial refinement templates that capture evolution scenarios, and associated preconditions, not covered before. Finally, by analyzing 79218 commits from the Linux repository, we find evidence that the proposed templates could cover a number of practical evolution scenarios.","PeriodicalId":128559,"journal":{"name":"Proceedings of the 20th International Systems and Software Product Line Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122893881","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}

Moreover, we provide two algorithms for detecting all such interactions with little measurement effort and potentially guaranteed accuracy and confidence level.

Due to conflicting requirements, software is developed in multiple variants to satisfy the needs of individual customers. While software product lines allow the efficient development of a high number of variants, many projects in industrial software development start with few variants, where each variant is developed separately. Unfortunately, for an increasing number of variants, this clone-and-own approach becomes error-prone and unprofitable regarding synchronization of changes between variants. With VariantSync, we demonstrate a tool to reduce the gap between clone-and-own and product lines by automating the synchronization of software variants and simplifying a potential later transition to a product line.","PeriodicalId":128559,"journal":{"name":"Proceedings of the 20th International Systems and Software Product Line Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130341675","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}

This workshop aims to foster research about making the most of two main inputs for SPL migration: 1) domain knowledge and 2) existing legacy assets. Domain knowledge, usually implicit and spread across an organization, is key to define the SPL scope and to validate the variability model and its semantics. At the technical level, domain expertise is also needed to create reusable software components. Regarding legacy assets, they use to be similar product variants (e.g. requirements, models, source code etc.) that were implemented using ad-hoc reuse techniques such as clone-and-own. These assets can be leveraged in extractive SPL adoption processes. The workshop REverse Variability Engineering (REVE) attracts researchers and practitioners contributing processes, techniques, tools, or empirical studies related to the automatic, semi-automatic or manual extraction or refinement of SPL assets.","PeriodicalId":128559,"journal":{"name":"Proceedings of the 20th International Systems and Software Product Line Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123689489","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 cope with this problem, we present DyMMer, a tool to support the automatic extraction of quality measures from feature models in DSPLs.

Thus, a common practice is to clone and adapt existing systems to new customer requirements. With the extractive approach, those derived variants can be migrated into a software product line. However, changing to a new development process is risky and may result in unnecessary costs. Therefore, companies apply cost estimations to predict whether another development approach is beneficial. Existing cost models for software-product-line engineering focus on development from scratch. Contrarily, the extractive approach is more common in practice but specialized models are missing. Thus, in this work we focus on product-line extraction from a set of legacy systems. We i) describe according cost factors, ii) put them in context with the development process and cost curves, and iii) identify open challenges in product-line economics. This way, our work supports cost estimations for the extractive approach and provides a basis for further research.","PeriodicalId":128559,"journal":{"name":"Proceedings of the 20th International Systems and Software Product Line Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115353503","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}
