[jira] [Commented] (QPID-6695) Make model tasks have useful
toStrings so that task submit/completion debug logs are useful
[ https://issues.apache.org/jira/browse/QPID-6695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14697288#comment-14697288 ]
Keith Wall commented on QPID-6695:
----------------------------------
The approach that looks most appealing is to enhance Task so it is capable of encapsulating the action, the subject and object of the action. TaskExecutor implementation would then be changed to log these details in a standard fashion. However, this change is impeded by the variety of ways in which we represent actions; sometimes we use Task, sometimes Callback, sometimes Runnable. On some code paths, Callables are wrapped in Tasks only to be wrapped in Callbacks again! This makes giving consistent logging more difficult. It seems that refactoring TaskExcecutor is the logical place to start.

> At the moment, when running the Broker at debug, we currently write the following as each task is submitted to the task executor:
> {noformat}
> 2015-07-31 15:29:45,096 DEBUG [VirtualHostNode-bdb-Config] (o.a.q.s.c.u.TaskExecutorImpl) - Task org.apache.qpid.server.model.AbstractConfiguredObject$2@201982d
> is performed successfully with result: null
> 2015-07-31 15:29:45,116 DEBUG [VirtualHostNode-bdb-Config] (o.a.q.s.c.u.TaskExecutorImpl) - Task org.apache.qpid.server.model.AbstractConfiguredObject$2@73dc353
> 4 is performed successfully with result: null
> {noformat}
> The ability to diagnose errors would be improved if the logging were improved to include the details of the operation and the action being performed.
