Rodin Platform 3.1 Release Notes

From Event-B
Jump to: navigation, search

What's New in Rodin 3.1?

  • Copy/Paste of components (machines/contexts/…) from Event-B Explorer.
  • Show/Hide elements inherited from abstractions in Rodin Editor (abstract invariants/guards/…):

This noticeably lightens model display in refinements.
  • Better proving support for theories (improved sequent translation for external provers).
  • Improved management of obsolete proofs: now, even a proof that contains rules from an invalid reasoner (old version or not installed) is properly displayed in the Proof Skeleton View.

In this case, an old version of 'simplification rewrites' has been used; running 'Proof Replay on Undischarged POs' will replay the old proof with the current version of the reasoner.

Changes for plug-in developers

Rodin 3.1 is built on top of Eclipse 4.4.1 (Luna).

Upgrading from Rodin 3.0

Rodin 3.1 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 3.1. Technically speaking, it's because of hidden package dependencies in Eclipse 4 that are not automatically discovered by the update manager. Thus, Rodin 3.1 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

  • 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.
