ReCooPLa: a DSL for Coordination-based Reconfiguration of Software Architectures

Authors: Flávio Rodrigues, Nuno Oliveira, and Luís S. Barbosa

Published in: OASIcs, Volume 38, 3rd Symposium on Languages, Applications and Technologies (2014)

Abstract

In production environments where change is the rule rather than the exception, adaptation of software plays an important role. Such adaptations presuppose dynamic reconfiguration of the system architecture, however, it is in the static setting (design-phase) that such reconfigurations must be designed and analysed, to preclude erroneous evolutions. Modern software systems, which are built from the coordinated composition of loosely-coupled software components, are naturally adaptable; and coordination specification is, usually, the main reference point to inserting changes in these systems. In this paper, a domain-specific language—-referred to as ReCooPLa--is proposed to design reconfigurations that change the coordination structures, so that they are analysed before being applied in run time. Moreover, a reconfiguration engine is introduced, that takes conveniently translated ReCooPLa specifications and applies them to coordination structures.

Slicing Functional Programs by Calculation

Authors: Nuno Miguel Feixa Rodrigues and Luís S. Barbosa

Published in: Dagstuhl Seminar Proceedings, Volume 5451, Beyond Program Slicing (2006)

Abstract

Program slicing is a well known family of techniques used to identify code fragments which depend on or are depended upon specific program entities. They are particularly useful in the areas of reverse engineering, program understanding, testing and software maintenance. Most slicing methods, usually targeting either the imperative or the object oriented paradigms, are based on some sort of graph structure representing program dependencies. Slicing techniques amount, therefore, to (sophisticated) graph transversal algorithms. This paper proposes a completely different approach to the slicing problem for functional programs. Instead of extracting program information to build an underlying dependencies’ structure, we resort to standard program calculation strategies, based on the so-called Bird-Meertens formalism. The slicing criterion is specified either as a projection or a hiding function which, once composed with the original program, leads to the identification of the intended slice. Going through a number of examples, the paper suggests this approach may be an interesting, even if not completely general alternative to slicing functional programs.
