However, we still It is not known whether feature dependencies are prone to change during the lifetime of configurable systems. To minimize this lack, we perform an empirical study to assess the evolution of feature dependencies. We focus in feature dependencies at the source-code level written with preprocessor directives, for this, we analyze the history of feature dependency changes in 15 preprocessor based systems written in C. In order to identify the most common types of changes on feature dependencies, we propose a catalog of possible changes in these dependencies. We found out that about 9% of the feature dependencies between two subsequent versions are added, and less of 4% are excluded. Whereas, about 87% of the dependencies between two subsequent versions are preserved, and 14% has some kind of structural modification. Besides, the results show that functions are 3x more prone to change than variables in feature dependencies. In summary, our results show that: (i) feature dependencies prone to be preserved during the evolution; (ii) about 1/5 of the dependencies preserved between two versions have structural changes; (iii) functions changes more than variables; (iv) developers may have to deal with 1/4 of the dependencies on each evolution of the configurable system.","PeriodicalId":300036,"journal":{"name":"Proceedings of the 13th International Workshop on Variability Modelling of Software-Intensive Systems","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133888770","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}

Especially software developers are heavily relying on such systems to identify solutions for their problems. While the content of community-question-answering systems may be less scientific, it usually represents practical knowledge from various perspectives and backgrounds. Thus, analyzing this content can be valuable for the scientific community to understand previous and current (i.e., open questions) needs of practitioners. In this paper, we report a systematic analysis of two websites that comprise communities with a focus on software development: Stack Exchange and Quora. We extract questions, answers, comments, and discussions on software product lines in general and feature modeling in particular. The results provide a historical perspective, an overview on commonly addressed scopes, and a classification of discussed topics and problems. Moreover, our findings are interesting to understand the practical impact of software-product-line techniques outside of well-analyzed case studies, to support lectures by identifying regularly asked questions, and to scope tool development based on reported technical problems.","PeriodicalId":300036,"journal":{"name":"Proceedings of the 13th International Workshop on Variability Modelling of Software-Intensive Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122380941","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}

Previous works have proposed classifying product line evolution into safe or partially safe, depending on the number of products that have their behavior preserved after evolution. Based on these notions, it is possible to derive transformation templates that abstract common evolution scenarios, such as adding an optional feature. However, existing works are focused on evaluating either safe or partially safe templates. Hence, in this work we aim to characterize product line evolution as a whole, measuring to what extent the evolution history is safe compared to partially safe, to better understand how product lines evolve. We measure how often existing templates happen using 2,300 commits from an open-source product line. According to our study, 91.7% of the commits represent partially safe evolution scenarios. Our results also show that 1,800 of these commits can automatically be classified as instances of existing templates. Among these, commits that do not modify other variability-aware models, are the most frequent, accounting for 72.3% out of the total of commits. For the remaining 500 commits, we identify that 24.4% are related to changes in the configuration knowledge, that is, the file responsible for the mapping between features and code.","PeriodicalId":300036,"journal":{"name":"Proceedings of the 13th International Workshop on Variability Modelling of Software-Intensive Systems","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127671249","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}
