  1. Tijs van der Storm Component-Based Configuration, Integration and Delivery

  2. Introduction • Me: Tijs van der Storm • Phd project “Deliver” • Intelligent Knowledge Management for Software Delivery • Collaboration CWI/University of Utrecht • Focus: • Improving Software Configuration Management (SCM) in Component-Based Software Engineering (CBSE)

  3. Component-Based SCM • SCM: know the state of the product at all times • Controlled evolution of software artifacts • Selection and configuration of artifacts • CBSE: components, interface, dependencies • Reduce complexity (factoring) • Increase time-to-market (parallelism) • Problem: no identification of compositions • No support for architectural variation and evolution • Impairs tracking, release and delivery

  4. Traceability issues • Lack of identification impairs tracing: • Which version of a dependency was used during this build? • Which versions of components are installed at the customer site? • What is the difference between release X and Y? • How to produce an update between from X to Y? • The answers are in the Bill of Materials (BOM)

  5. Approach: extend continuous integration • BOMs derive from Continuous Integration • Build compositions on every affecting change • Identify the input to the build (transitively) • Store results in database • Benefits • Fully automatic • Fully reproduceable builds • Push button releases • “Pure” distributions

  6. Results and ongoing work • Sisyphus Continuous Integration Tool • Incremental & backtracking for optimal results • Populates the Bills of Materials database • Current work: architectural evolution • Temporary (branches) • Permanent (variants) • Towards compositional SCM
