D45 General Platform Maintenance

Overview

The Rodin platform versions concerned by this deliverable are:

• 2.1(08.02.2011),
• 2.2(01.06.2011),
• 2.2.2(01.08.2011),
• 2.3(04.10.2011),
• 2.4(31.01.2011),
• 2.5(30.04.2011).

This year, the maintenance carried on fixing identified bugs, although an emphasis has been put on correcting usability issues. Indeed, during the meeting in Nice, the WP9 members agreed to refocus on the needed tasks to address some specific bugs and issues reported by DEPLOY partners, and wished resolved by the end of DEPLOY. Thus, no new features were implemented but those appearing in the description of work. The tasks to be performed by the WP9 members were then scheduled, prioritized and regularly updated during the WP9 bi-weekly meetings. The following paragraphs will give an overview of the the work that has been performed concerning maintenance on the existing platform components (i.e. core platform and plug-ins).

See the Release Notes and the SourceForge databases (bugs and feature requests) for details about the previous and upcoming releases of the Rodin platform.

• Core platform maintenance (Thomas Muller)

According to the previously mentionned refocus, the maintenance tasks performed on the core plateform basically aimed to overcome Rodin scalability weaknesses, and the continuous need of seamless proving experience. The performance was enhanced by core implementation and user interface refactorings. The proving usability was enhanced by the possibility to customize, combine, and parameterize tactics and the addition of new inference and rewriting rules.

Motivations

Platform maintenance

The DEPLOY partners raised issues that appeared mandatory to address by the end of the project. The tasks to address these issues have been listed and grouped according to their priority. The group 1 has the highest priority, the group 2 has an intermediate priority,and the group 3 has the lowest priority. The group 4 concerns topics that could not be ressourced during the lifetime of DEPLOY. Although the Prover Integrity item not being directly covered, the WP9 members managed to partially address it thanks to Isabelle and SMT integration. Export of full proofs is beyond the scope of DEPLOY.

Group 1 (highest priority)	Responsible
Performance - Core (large models, etc.) - GUI (incl. prover UI, edition, etc.)	Systerel
Prover Performances - New rewriting rules / inference rules - Automatic tactics (preferences, import/export, timeout,etc.)	Systerel
ProB Disprover (incl. counter examples to deadlock freedom POs)	Düsseldorf
Stability (crash, corruption, etc.)	Systerel
Editors	Systerel/Düsseldorf

Group 2	Responsible
Prover Performances - SMT provers integration - connection with Isabelle - Mathematical extensions - ProB	Systerel ETH Zurich Southampton/Systerel Düsseldorf
Scalability - Decomposition - Modularisation plug-in - Team-based development	Southampton Newcastle Southampton
Plug-in incompatibilities	Newcastle
Model-based testing	Pitesti/Düsseldorf
ProR	Düsseldorf

Group 3	Responsible
Scalability - Generic instantiation - UML-B maintenance	Southampton ETH Zurich/Southampton
Code Generation	Southampton

Group 4	Responsible
Prover Integrity
Integrity of Code Generation
