Brian Stansberry created WFCORE-3628: ---------------------------------------- Summary: Ensure services installed by HostControllerService and ApplicationServerService are tracked by the ContainerStateMonitor Key: WFCORE-3628 URL: https://issues.jboss.org/browse/WFCORE-3628 Project: WildFly Core Issue Type: Enhancement Components: Domain Management Reporter: Brian Stansberry Assignee: Brian Stansberry WFCORE-3624 is a specific example of a more general problem -- services that may be recorded as dependencies of services installed by management ops are not tracked by the ContainerStateMonitor. This makes it possible to get problems like WFCORE-3624. In practice WFCORE-3624 is fairly unique, as the problem service was ON_DEMAND. Also, most services installed by HostControllerService and ApplicationServerService are themselves dependencies of DomainModelControllerService and ServerService (which provide the ModelController) so if they are not started no management ops can proceed. But the code would be more robust if the way these were installed involved logic that led to them being tracked by the StabilityMonitor used by ContainerStateMonitor. Doing this would help ensure that future services like this don't fall into a crack the way ExternalManagementRequestExecutor did. Note -- I don't think DomainModelControllerService and ServerService themselves should be monitored. Not HostControllerService and ApplicationServerService either. Here's some analysis I did when trying to figure out WFCORE-3624: HostControllerService --------------------- ProcessControllerConnectionService -- DMCS depends HostControllerExecutorService -- DMCS depends HostPathManagerService - DMCS depends HostControllerScheduledExecutorService -- no dep Value<ProductConfig> -- no dep ExternalManagementRequestExecutor -- no dep ApplicationServerService ------------------------ ContentRepositoryImpl or RemoteFileRepositoryService -- SS depends ContentCleanerService -- no dep ServerDeploymentRepositoryImpl -- SS depends ServiceModuleLoader -- SS depends ExternalModuleService -- SS depends ServerPathManagerService -- SS depends ServerEnvironmentService -- no dep Value<ProductConfig> -- no dep ServerExecutorService -- SS dep *if* executor is configured ServerScheduledExecutorService -- no dep ExternalManagementRequestExecutor -- no dep -- This message was sent by Atlassian JIRA (v7.5.0#75005)
