D32 General Platform Maintenance

Overview

The main goal of the platform corrective and evolutive maintenance is to fix the listed known bugs, and implement some new requested features. As in the previous years of Deploy, these bugs and features are reported either by mail or through dedicated SourceForge trackers.

The terse list below gives an overwiew of the noteworthy features added in the main platform during the past year:

• Proof replay of undischarged POs

It often happens, while modifying a model, that a set of previously manually discharged POs are slightly changed and need to be discharged again. However, replaying the proof for those POs could most of the time be enough to discharge it. Hence, a command was added to manually try replaying the proofs for a set of undischarged POs.

• Rule Details View

When doing an interactive proof, one is guided by the proof tree appearing on the proof tree view. However, it is sometimes needed to get more informations about the rules being involved in a proof, such as instantiation details, hidden hypotheses, etc. A view displaying such details has been added.

• Refactoring plug-in

• Documentation

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

Motivations

The main evolutions of the Rodin platform are driven by the description of work for the DEPLOY project and the requirements expressed by industrial WP1 to WP4 partners or by advanced users during the lifecycle of the project.

The priorities are discussed during the WP9 meetings (bi-weekly management conference call, WP9 face-to-face meetings during DEPLOY workshops).

Choices / Decisions

The WP9 partners have agreed on a release policy (see the Rodin Platform Releases wiki page). In particular:

• A new version of the Rodin platform is released every 3 months.
• The code is frozen during the 2 weeks preceding each release.
• The Eclipse versioning policy is enforced (See Version Numbering).
• A wiki page is dedicated to each release.

The main advantages, for both developers and end-users, are summarized below:

• Information. The wiki page dedicated to each release provides instant information on the new features and improvements, which may be discussed if necessary.
• Validation. The period of code freeze is more especially devoted to bug fixes, and the frequency of the stable releases is ensured.
• Integration. A synchronization between the optional plug-ins and other plug-ins is now possible.
