Almost every software system provides configuration options to tailor the system to the target
platform and application scenario. Often, this configurability renders the analysis of every …

The advent of variability management and generator technology enables users to derive
individual system variants from a configurable code base by selecting desired configuration …

The C preprocessor is used in many C projects to support variability and portability.
However, researchers and practitioners criticize the C preprocessor because of its negative …

The bioinformatics software domain contains thousands of applications for automating tasks
such as the pairwise alignment of DNA sequences, building and reasoning about metabolic …

Abstract Maintenance consumes 40% to 80% of software development costs. So, it is
essential to write source code that is easy to understand to reduce the costs with …

Configurable software makes up most of the software in use today. Configurability, ie, the
ability of software to be customized without additional programming, is pervasive, and due to …

Preprocessor directives (# ifdefs) are often used to implement compile-time variability,
despite the critique that they increase complexity, hamper maintainability, and impair code …

The C preprocessor is a simple, effective, and language-independent tool. Developers use
the preprocessor in practice to deal with portability and variability issues. Despite the …

In order to get insight into challenges with quality in highly-configurable software, we
analyze one of the largest open source projects, the Linux kernel, and quantify basic …

Context: Maintaining software families is not a trivial task. Developers commonly introduce
bugs when they do not consider existing dependencies among features. When such …
