Opening sirius session [message #1808424]

While opening a sirius session for the very first time in Workspace, editor is getting opened nearly after 10 secs. While opening the sirius session there is a call to initialize Model Accessor, here all the ecore models(created for custom use as well as the ecore model in dependent plugins) are being loaded and assigned to a static reference.

The line below is how that static object is intialized in org.eclipse.sirius.ecore.extender.business.internal.accessor.ecore.EcoreIntrinsicExtender class

private static PackageRegistryIndex platformIndex = new PackageRegistryIndex(EPackage.Registry.INSTANCE, Predicates.<EPackage> alwaysTrue());

It seems due to this opening of session gets time for the very first time. Is this can be prevented or any work around to reduce the time consumption

To prevent this ecore package indexing used the system property org.eclipse.sirius.enableUnsafeOptimisations and set it to true like

-Dorg.eclipse.sirius.enableUnsafeOptimisations=true

With this it seems no issues found with our use case, we want to ensure this. So any points on this system property usage is welcome. Thanks in advance

Hello,

Indeed, this option prevent some indexing and notification. If your VSM is deployed in a .odesign file, and you don't register new metamodels on the fly, you should be able to use this optimization without trouble.

Regards,
Steve
