Rodin Platform 1.3 Release Notes

What's New in Rodin 1.3?

• General Interface

Error log view is now available among the other General views. It is accessible through Window > Show view > Other... and shows the contents of the log file. This provides very useful informations to developers for correcting bugs, and is intended to be copy/pasted by users when posting bug reports.

• Modelling

New in component popup menu. "New Event-B Project" and "New Event-B Component" wizards have been added to the "New" context menu of the Event-B Explorer. Right-clicking in a blank part or on a project in the Event-B Explorer, a popup appears; then in the "New" section, these two actions are proposed. The wizards are those that also appear when clicking the buttons at the top of the Event-B Explorer, or through File > New.

new preference/properties mechanism. A new preference/properties mechanism to handle and use prefix settings. It is now possible to set prefixes for a workspace scope or a project scope. Prefix settings are extended automatically by editor contributions.

• Building

Direct children processing only. The builder now only processes direct children of project. Files located in subfolders are ignored.

• Proving

The simplification rewrites tactic has been fixed: a clean has to be performed on all projects. Many proofs use this tactic and will be marked as broken, but correct ones will replay successfully (see next item).

A new "Replay Proof" command. Right-clicking any element in the Event-B Explorer shows the contextual menu, which contains a new command "Proof Replay on Undischarged POs" next to "Retry Auto Provers" and "Recalculate Auto Status".

See also: Proof Obligation Commands

NewPP. Changed the name displayed in proofs to "NewPP" to avoid ambiguity with "PP". It used to be displayed as "Predicate Prover".

• Changes for plugin-developers

Added the origin of predicates in a proof. In the sequent of the root node of a IProofTree, the IAxiom, IInvariant, ..., a predicate (hypothesis or goal) comes from can be fetched through the origin of its source location.

For instance: proofTree.getRoot().getSequent().goal().getSourceLocation().getOrigin()

Knowing nature of proof obligations. The nature of a proof obligation (Theorem, Well-Definedness, Invariant Preservation, ...) can be known from a IPOSequent.

See IPOGNature and IPOSequent#getPOGNature().

NewPP Plug-in. The newPP tactic has been published. See PPCore#newPP()

Added ExplorerPlugin#getSelectedStatuses(). Added a function ExplorerPlugin#getSelectedStatuses() to get the PS elements under the current explorer selection.

Extensible pretty print. It is now possible to extend the pretty print page with the same kind of mechanism used to extend the structured editor.

Requirements

• It is recommended to run the Rodin platform with a Java 1.5 Runtime Environment.
• Only a 32-bit version of the Rodin platform is provided. Some optional libraries dedicated to 32-bit support may be required in order to run it on a 64-bit OS. Moreover, you will have to install a 32-bit Java Virtual Machine (JVM), and then to set the -vm option to make sure that Rodin is run with the correct JVM.

eg. /usr/local/rodin/rodin -vm /usr/lib/jvm/ia32-java-1.5.0-sun/bin/java (You have to adjust paths to your system.)

Known Issues

[bugs page]

• Early releases of XULRunner 1.9.1 may cause an SWT exception that prevents from opening an editor (as well as any browser-based ui component). More recent releases fix this bug (works fine with xulrunner-1.9.1.7). Alternatively, it is possible to specify XULRunner path to point to 1.9.0: edit "rodin.ini" and add the following line:

-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.0.14

where "/usr/lib/xulrunner-1.9.0.14" must be replaced with your actual XULRunner 1.9.0 installation directory.

• A warning like the following one is displayed to the standard output when platform starts on GNOME desktop:

(rodin:17254): GLib-WARNING **: g_set_prgname() called multiple times

It's a GNOME bug, referenced at: [[1]]

• The error log shows the following problem:

org.osgi.framework.BundleException: The bundle could not be resolved. Reason: Missing Constraint: Import-Package: org.eclipse.equinox.internal.util.event; version="1.0.0"
at org.eclipse.osgi.framework.internal.core.AbstractBundle.getResolverError(AbstractBundle.java:1313)
...

It's an Eclipse 3.5 bug. Information found there: [[2]]
