Abstract

The mainstream adoption of free and open source software (FOSS) has widely popularised notions like software packages or plugins, maintained in a distributed fashion and evolving at a very quick pace. Each of these components is equipped with metadata, such as dependencies, which define the other components it needs to function properly, and the incompatible components it cannot work with. In this paper, we introduce the notion of strong conflicts, defined from the component dependencies, that can be effectively computed. It gives important insights on the quality issues faced when adding or upgrading components in a given component repository, which is one of the facets of the predictable assembly problem.Our work contains concrete examples drawn from the world of GNU/Linux distributions, that validate the proposed approach. It also shows that the measures defined can be easily applied to the Eclipse world, or to any other coarse-grained software component model.
