Logging is a common programming practice of practical importance to collect system runtime information for postmortem analysis. Strategic logging placement is desired to cover necessary runtime information without incurring unintended consequences (e.g., Performance overhead, trivial logs). However, in current practice, there is a lack of rigorous specifications for developers to govern their logging...
Preprocessors (e.g., cpp) provide simple means to manage software product variants by including/excluding required feature code to/from base program. Feature-related customizations occur at variation points in base program marked with preprocessing directives. Problems emerge when the number of inter-dependent features grows, and each feature maps to many variation points in many base program components...
Managing features that have fine-grained impact on base programs is a challenging task in software product line development. Despite well-known problems, preprocessing (e.g., cpp) is often used to handle features by including/excluding variant code to/from a base program. In this paper, we show how some of common preprocessing problems can be alleviated with a query-based environment that assists...
