[jboss-jira] [JBoss JIRA] (WFCORE-488) Failures of undeploy of a partially failed deployment

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13042583#comment-13042583 ] 

Brian Stansberry commented on WFCORE-488:
-----------------------------------------

The failure information is correctly getting back to the master HC, but DomainFinalResultHandler ends up discarding it because the slave HCs are reporting failures as well. Basically the scenario I speculated on at https://issues.jboss.org/browse/AS7-4597?focusedCommentId=12688863&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12688863.

So I need to work out how to better handle that.

> Undeploy failed: JBAS010839: Operation failed or was rolled back on all servers.
> {noformat}
> There are several issues at play here:
> # Insufficient information is displayed along with JBAS010839
> # No actual failure logged either in DC or in individual host's logs
> # Failure to find a deployment unit on a particular host should not result in a failure of a domain-wide undeploy in DeploymentUndeployHandler
> I'll start in a reverse order of causation:
> In DeploymentUndeployHandler.execute
> {noformat}
>     public void execute(OperationContext context, ModelNode operation) throws OperationFailedException {
>         ModelNode model = context.readResourceForUpdate(PathAddress.EMPTY_ADDRESS).getModel();
> ...
> {noformat}
> OperationContextImpl.readResourceForUpdate calls OperationContextImpl.requireChild:
> {noformat}
>     private static Resource requireChild(final Resource resource, final PathElement childPath, final PathAddress fullAddress) {
>         if (resource.hasChild(childPath)) {
>             return resource.requireChild(childPath);
>         } else {
>             PathAddress missing = PathAddress.EMPTY_ADDRESS;
>             for (PathElement search : fullAddress) {

>                 if (search.equals(childPath)) {
>                     break;
>                 }
>             }
>             throw ControllerMessages.MESSAGES.managementResourceNotFound(missing);
>         }
>     }
> {noformat}
> The exception generated by {{throw ControllerMessages.MESSAGES.managementResourceNotFound(missing);}}: 
> # does not propagate from the host to DC and to CLI
> # is not logged with any level (not even TRACE) either on host or DC
> # should be handled within DeploymentUndeployHandler not to fail the undeploy operation in case of a partially failed deployment (e.g. EAR with unsatisfied CDI dependencies).
