However, with an increasing number of cloned systems, the problems of this approach become severe, due to synchronization efforts. In such cases, organizations often decide to extract a software product line, which promises to reduce development and maintenance costs. While this scenario is common in practice, the research community is still missing knowledge about best practices and needs datasets to evaluate supportive techniques. In this paper, we report our experiences with extracting a preprocessor-based software product line from five cloned Android games of the Apo-Games challenge. Besides the process we employed, we also discuss lessons learned and contribute corresponding artifacts, namely a feature model and source code. The insights into the processes help researchers and practitioners to improve their understanding of extractive software-product-line adoption. Our artifacts can serve as a valuable dataset for evaluations and can be extended in the future to support researchers as a real-world baseline.","PeriodicalId":417872,"journal":{"name":"Proceedings of the 23rd International Systems and Software Product Line Conference - Volume A","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115501556","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}

Annotating or creating an orthogonal decomposition of code in terms of features implies extra effort, as well as massive and cumbersome refactoring activities. In this paper, we introduce an approach for identifying and visualizing the variability implementation places within the main decomposition structure of object-oriented code assets in a single variability-rich system. First, we propose to use symmetry, as a common property of some main implementation techniques, such as inheritance or overloading, to identify uniformly these places. We study symmetry in different constructs (e.g., classes), techniques (e.g., subtyping, overloading) and design patterns (e.g., strategy, factory), and we also show how we can use such symmetries to find variation points with variants. We then report on the implementation and application of a toolchain, symfinder, which automatically identifies and visualizes places with symmetry. The publicly available application to several large open-source systems shows that symfinder can help in characterizing code bases that are variability-rich or not, as well as in discerning zones of interest w.r.t. variability.","PeriodicalId":417872,"journal":{"name":"Proceedings of the 23rd International Systems and Software Product Line Conference - Volume A","volume":"31 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124657781","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}

A number of systematic literature reviews exist that identify the main characteristics offered by existing tools and the SPL phases in which they can be applied. However, these reviews do not really help to understand if those tools are offering what is really needed to apply SPLs to complex projects. These studies are mainly based on information extracted from the tool documentation or published papers. In this paper, we follow a different approach, in which we firstly identify those characteristics that are currently essential for the development of an SPL, and secondly analyze whether the tools provide or not support for those characteristics. We focus on those tools that satisfy certain selection criteria (e.g., they can be downloaded and are ready to be used). The paper presents a state of practice with the availability and usability of the existing tools for SPL, and defines different roadmaps that allow carrying out a complete SPL process with the existing tool support.","PeriodicalId":417872,"journal":{"name":"Proceedings of the 23rd International Systems and Software Product Line Conference - Volume A","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129194769","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}

Family-based analysis techniques operate on a single artifact, referred to as a family model, that is annotated with variability constraints. This modeling approach paves the way for efficient model-based testing and model checking for SPLs. Albeit reasonably efficient, the creation and maintenance of family models tend to be time consuming and error-prone, especially if there are crosscutting features. To tackle this issue, we introduce FFSMDiff, a fully automated technique to learn featured finite state machines (FFSM), a family-based formalism that unifies Mealy Machines from SPLs into a single representation. Our technique incorporates variability to compare and merge Mealy machines and annotate states and transitions with feature constraints. We evaluate our technique using 34 products derived from three different SPLs. Our results support the hypothesis that families of Mealy machines can be effectively merged into succinct FFSMs with fewer states, especially if there is high feature sharing among products. These indicate that FFSMDiff is an efficient family-based model learning technique.","PeriodicalId":417872,"journal":{"name":"Proceedings of the 23rd International Systems and Software Product Line Conference - Volume A","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127661128","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}

Microservice architecture is widely used to overcome the limitations of monolithic legacy systems, such as limited maintainability and reusability. Migration to a microservice architecture is increasingly becoming the focus of academic research. However, there is little knowledge on how microservices are extracted from legacy systems in practice. Among these limitations, there is a lack of understanding if variability is considered useful along the microservice extraction from a configurable system. In order to address this gap, we performed an exploratory study composed of two phases. Firstly, we conducted an online survey with 26 specialists that contributed to the migration of existing systems to a microservice architecture. Secondly, we performed individual interviews with seven survey participants. A subset of the participants (13 out of 26) dealt with systems with variability during the extraction, which stated that variability is a key criterion for structuring the microservices. Moreover, variability in the legacy system is usually implemented with simple mechanisms. Finally, initial evidence points out that microservices extraction can increase software customization.","PeriodicalId":417872,"journal":{"name":"Proceedings of the 23rd International Systems and Software Product Line Conference - Volume A","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126732280","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}
