[jboss-jira] [JBoss JIRA] (WFCORE-3327) Confusing between recording of the org.wildfly.remoting.endpoint and the resource that configures it

Brian Stansberry created WFCORE-3327: ---------------------------------------- Summary: Confusing between recording of the org.wildfly.remoting.endpoint and the resource that configures it Key: WFCORE-3327 URL: https://issues.jboss.org/browse/WFCORE-3327 Project: WildFly Core Issue Type: Bug Components: Domain Management, Remoting Affects Versions: 3.0.3.Final Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: 4.0.0.Beta1 The org.wildfly.remoting.endpoint capability is reported by the /subsystem=remoting resource, but it is the /subsystem=remoting/configuration=endpoint that actually configures it. This is confusing for humans and difficult for tooling like the new provisioning tools. The configuration=endpoint child is essentially a singleton and internally it just provides configuration to its parent. Further, if the user does not configure this resource, a default one is added automatically. This child resources is really just a configuration chunk for its parent. In the end it is the parent resource that actually provides the capability, by installing a service. It reads its child resource to configure the capability. There are a couple possibilities here: 1) Simply move the declaration of the capability to the child resource. Per discussion with [~aloubyansky] is seems that solves the tool problem. It leaves the actual situation obscure though, because now a seemingly non-required child resource is the thing that provides a capability that actually will always be present. 2) Deprecate that child resource and add a complex attribute to the parent. The child resource continues to exist in the API for compatibility reasons, but simply modifies the attribute on the parent. The cap remains on the parent. Note that 2) may require some manipulation of how we handle undefined complex attributes; i.e. that when we resolve them, even if the root attribute is undefined, we need to resolve the fields, in case those have default values, with the resolved parent then including the default field values. That can be tricky though, e.g. in cases of things like the defaulted attribute having requires, or other fields in the complex attribute being required. This latter point is relevant because it would be a 'worker' field in a complex attribute that would actually declare the name of the needed io worker capability. That field would have a default value 'default'. Perhaps the declaration of the complex attribute itself (i.e. ObjectTypeAttributeDefinition) would need to indicate how things should be handled. That could just be the complex attribute itself has a default value, {"worker"=>"default"}. Or it could be a flag that enables looking at the fields for defaults if the top level attribute is undefined. Or maybe investigation will show this isn't a problem at all. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
