All contributors of the "org.eclipse.core.resources.modelProviders" extension point will be eagerly (and uselessly) activated through org.eclipse.team.core.mapping.provider.SynchronizationScopeManager.getMappings(IModelProviderDescriptor, ResourceTraversal[], ResourceMappingContext, IProgressMonitor) This method properly retrieves the array of "matching" traversals for the model provider descriptor (according to their "enablement" value)... but doesn't check for the potential emptiness of this array before calling "descriptor.getModelProvider", which will activate the contributing plugin even if there isn't a reason to. This is the same kind of issue that's been resolved in org.eclipse.team.internal.ui.mapping.ModelEnablementPreferencePage.getLabel(IModelProviderDescriptor) through bug 133604. Basically, ResourceTraversal[] matchingTraversals = descriptor.getMatchingTraversals(traversals); return descriptor.getModelProvider().getMappings(matchingTraversals, context, monitor); should be changed to ResourceTraversal[] matchingTraversals = descriptor.getMatchingTraversals(traversals); if (matchingTraversals.length > 0) return descriptor.getModelProvider().getMappings(matchingTraversals, context, monitor); return new ResourceMapping[0];
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
