“…Feature location is an activity for recovering the traceability of some pre-existing features to the reusable code assets in an SPL [16,50]. Whereas, feature identification is an activity for identifying the common and varying units, as potential features, among some related software systems [41,68]. In both cases, a set of clone-and-own or legacy systems are analysed.…”

In many variability-intensive systems, variability is implemented in code units provided by a host language, such as classes or functions, which do not align well with the domain features. 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.

“…To understand variability and to identify the statistical data describing the commonality and variability across PVs of each android family, we develop a process presented in Figure 3. This process extends the BUT4Reuse (Bottom-Up-Technologies for Reuse) framework [9] to analyze commonality and variability corresponding to each RQ. We select to extend BUT4Reuse because: (i) it is generic that allows to use it to analyze different software artifact types (e.g., source code and XML configuration files), and (ii) it is an open-source extensible framework that allows us to (re)implement new algorithms, visualization capabilities and metric extractors.…”

Software developers rely on the clone-and-own approach to rapidly develop software product variants (PVs) that meet variability in market needs. To improve the comprehension of how PVs are evolved and varied, we analyze the clone-andown practices applied by developers of these PVs. We perform an empirical study on 75 android families to gain insights about observable phenomena related to the commonality and variability between the source code of PVs of these families.In particular, we study three research questions to identify the commonality and variability related to the organization of source code files, cloning Java methods, and configuration parameters of AndroidManifest.xml files. The results show that cloning packages, Java files and Java methods is a common practice used by developers of all android families. Maintainers should put efforts for managing the diverse implementations (bodies) of the modified cloned methods and it is essential to consider the commonality and variability of configuration parameters.

Much has been investigated about software reuse since the software crisis. The development of software reuse methods, implementation techniques, and cost models has resulted in a significant amount of research over years. Nevertheless, the increasing adoption of reuse techniques, many of them subsumed under higher level software engineering processes, and advanced programming techniques that ease the way to reuse software assets, have hidden somehow in the recent years new research trends on the practice of reuse and caused the disappearance of several reuse conferences. Also, new forms of reuse like open data and feature models have brought new opportunities for reuse beyond the traditional software components.From past to present, we summarize in this research the recent history of software reuse, and we report new research areas and forms of reuse according to current needs in industry and application domains, as well as promising research trends for the upcoming years.
