FEVER: An approach to analyze feature-oriented changes and artefact co-evolution in highly configurable systems

The evolution of highly configurable systems is known to be a challenging task. Thorough understanding of configuration options their relationships, and their implementation in various types of artefacts (variability model, mapping, and implementation) is required to avoid compilation errors, invalid products, or dead code. Recent studies...

Analysing the Linux kernel feature model changes using FMDiff

Evolving a large scale, highly variable system is a challenging task. For such a system, evolution operations often require to update consistently both their implementation and its feature model. In this context, the evolution of the feature model closely follows the evolution of the system. The purpose of this work is to show that fine...

Fever: Extracting feature-oriented changes from commits

The study of the evolution of highly configurable systems requires a thorough understanding of thee core ingredients of such systems: (1) the underlying variability model; (2) the assets that together implement the configurable features; and (3) the mapping from variable features to actual assets. Unfortunately, to date no systematic way to...

Safe Evolution Patterns for Software Product Lines

Despite a global recognition of the problem, and massive investment from researchers and practitioners, the evolution of complex software systems is still a major challenge for today’s architects and developers. In the context of product lines, or highly configurable systems, variability in the implementation and design makes many of the pre...

Evaluating Feature Change Impact on Multi-Product Line Configurations Using Partial Information

Evolving large-scale, complex and highly variable systems is known to be a difficult task, where a single change can ripple through various parts of the system with potentially undesirable effects. In the case of product lines, and moreover multi-product lines, a change may affect only certain variants or certain combinations of features, making...

Extracting Feature Model Changes from the Linux Kernel Using FMDiff

The Linux kernel feature model has been studied as an example of large scale evolving feature model and yet details of its evolution are not known. We present here a classification of feature changes occurring on the Linux kernel feature model, as well as a tool, FMDiff, designed to automatically extract those changes. With this tool, we...
