Rodin Platform 3.2 Release Notes

What's New in Rodin 3.2?

Rodin 3.2 is mainly a corrective version of the Rodin platform. However, hereafter is a short review of newly implemented or fixed features.

• Selection is now preserved when elements are reordered

• Appearance preferences are now handled by the Rodin Editor

User defined foreground color and comment foreground color are now taken into account in the Rodin Editor.
Moreover, new color features are now handled by the Rodin Editor.
These preferences now appear from the Rodin color and Fonts preferences accessible via Window > Preferences > General > Appearance > Colors and Fonts

• Tactics can now be cancelled

Potentially long running tactics do not make the platform hang anymore and can now be cancelled.

• Symbol insertion now seamlessly works with the Rodin Editor

Mathematical symbols can now be inserted in text fields of the Rodin Editor.

Changes for plug-in developers

Rodin 3.2 is built on top of Eclipse 4.4.2 (Luna).

• Changes to org.eventb.ui.itemdescription.IAttributeDesc
  • The method isMath() has been added to the API. This method tells whether mathematical symbols from the attribute value should be translated. It returns false if the attribute in not a text attribute.

• Changes to org.eventb.ui.manipulation.IAttributeManipulation
  • The following information was added to getPossibleValues() method : The returned list must include the current value of the attribute, otherwise the display if the combo box will not be accurate on Linux and Mac OS X.

• Changes to org.eventb.core.ast.FormulaFactory
  • The method isValidPredicateName(String name) has been added to the API. It tells whether the given name is a valid predicate variable name (that is any identifier name prefixed by a $).

Upgrading from Rodin 3.0

Rodin 3.2 is based on Eclipse 4, whereas Rodin 3.0 was based on Eclipse 3. This change makes it impossible to upgrade from 3.0 to 3.2. Technically speaking, it's because of hidden package dependencies in Eclipse 4 that are not automatically discovered by the update manager. Thus, Rodin 3.2 must be downloaded.

Requirements - Compatibility

• Configurations supported (and for which binaries are provided)
  • Linux 32-bit
  • Linux 64-bit
  • Windows 32-bit
  • Windows 64-bit
  • Mac OS X 64-bit

• You need to have a Java JRE (6.0 or later) installed on your computer. The Rodin product will not work with a previous version. To run Rodin 64-bit, you need a 64-bit JRE.

• To enhance your proving experience, the eclipse font settings (size, aspect...) are available from the preferences (General > Appearance > Colors and Fonts > Rodin). These settings allow you to modify the properties set on the Event-B Keyboard Text Font which is used in many views of the Proving UI. However, to enjoy these functionnalities, you need to install the Brave Sans Mono font on your system. You can download this font from the link here.

• Linux with GTK and old glibc:

A crash or display issues may happen:

• glibc <= 2.13: SIGSEGV systematic at launch
• glibc 2.17: some actions have no effect, like right click actions in the Rodin Editor

See [1].

Solutions, one of:

1. upgrade glibc >= 2.19
2. export SWT_GTK3=0
3. edit rodin.ini, in the program argument part (before vmargs), add

--launcher.GTK_version
2

• Linux 64-bit:

package 'libc6-amd64:i386' must be installed, in particular in order to run external prover binaries

depending on the distribution, you could instead need these packages: lib32z1 lib32ncurses5 lib32bz2-1.0

• Windows 64-bit:

Atelier B provers work more slowly; it can cause ML to not automatically discharge some sequents that it discharges on windows 32-bit, due to its timeout. A workaround is to download a custom profile: DefaultAuto_ML800, then Window > Preferences > Event-B > Sequent Prover > Auto/Post Tactic > Profiles (tab) > Import..., point to the downloaded file, 'Select All' profiles (there are 2), OK. Then in 'Auto/Post Tactic' tab, select 'Default Auto Tactic Profile (ML 800)' profile for auto-tactics. It is the same as the 'Default Auto Tactic Profile', except ML has a longer timeout (800 ms). You can of course change this timeout by editing the 'ML (800)' profile.

We have not noticed this problem for Linux 64-bit, nor for other platforms; however if you do, the same workaround applies.

Disclaimer

Since Rodin is continuously maintained, several unsoundness bugs which have been encountered were investigated and fixed. However, despite the total commitment of our teams to ensure the soundness of the platform, some unexpected and unknown soundness issues could remain. We would be grateful if you would report these issues to the development mailing list.
