Re: [xwiki-devs] [Proposal] Component isolation implementations

Hi, We have the need to isolate groups of components. For ex a wiki macro created in a subwiki should only be visible in that subwiki by default. Here's an implementation proposal that I'm planning to implement: * There's a Root Component Manager (the current CM) * There are 3 components which implement the ComponentManager role and with 3 hints: "wiki", "user" and "all". There's a CompositeComponentManager class that allows chaining CM and the "all" CM chains the "default" (root CM), "wiki" CM and "user" CM. This works the same as with the configuration module. * Other components can have CMs injected as they want (if not specified then it's the default, etc). For ex: @Requirement("all") private ComponentManager cm * Creation process. As for now the user creates the root CM and then the annotation loader will create the descriptors for the other CMs and register them against the root CM. They'll get instantiated once (singleton) the first time they're looked up. * In order to register a component for, say, a given "enterprise" wiki, we need to add a new property to the ComponentDescriptor: get/ setAdditionalData(Object data). For example: wikiCM.registerComponent(CD mycd) where cd.setAdditionalData("enterprise"). * Last, Guice uses Modules to isolate component definitions so it should be possible and relatively easy to port the implementation to Guice (even though Guice uses static Modules we can make them dynamic).
