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 updates allowed to capture and integrate rapidly some minor changes to enhance the usability of the platform which were required by the DEPLOY partners. 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.

• General platform maintenance (Thomas Muller)

The maintenance done to overcome Rodin scalability weaknesses and enhance the proving experience will be detailed in a separate chapter. However, some features initially planned and those further added and prioritized are worth to mention and will be details in the Motivations section concerning platform maintenance.

• TODO An overview of the contribution about Mathematical extensions / Theory Plug-in (Issam Maamria)

• TODO An overview of the contribution about Plug-in Incompatibilities (All partners)

• TODO An overview of the contribution about Modularisation (Alexei Illiasov)

• TODO An overview of the contribution about Decomposition (Renato Silva)

• TODO An overview of the contribution about Team-based Development (Colin Snook, Vitaly Savicks)

• TODO An overview of the contribution about UML-B (Colin Snook, Vitaly Savicks)

• TODO An overview of the contribution about ProR (Michael Jastram)

Motivations

The tasks to solve the issues faced by the DEPLOY partners have been listed and being assigned to groups according to their priority. A high priority means a high need in the outcome of a given task. 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.The prover integrity item although not being directly covered, has been partially addressed thanks to Isabelle and SMT integration. Unfortunately, the originally planned export of full proofs and integrity check 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, timeout, etc.)	SYSTEREL
ProB Disprover (incl. counter examples to DLF 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 Zürich 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 Zürich/Southampton
Code Generation	Southampton

Group 4
Prover Integrity
Integrity of Code Generation

Platform maintenance

The platform maintenance, as it can be deduced from the above tables in section Motivations, mainly concerned stability and performance improvement. These topics will be discussed and detailed in a separate chapter about scalability improvements.
However, other prioritary improvements were added. These improvements or came from DEPLOY partners specific needs, or were corresponding to previously identified needs(listed in the D32 - Model Construction tools & Analysis III Deliverable).

Status

Platform maintenance

By the end of the project, there are :

• xx bugs reported and open. All with a priority lower or equal to 5.
• xx feature requests expressed and still open.

The necessary tasks have been performed in the last year of DEPLOY to make the platform usable and stable in an industrial context.
