Subject [jira] Commented: (CONTINUUM-2371) Unable to view queues after loss of build agent
Date Tue, 29 Sep 2009 20:58:35 GMT


Wendy Smoak commented on CONTINUUM-2371:

The second time I tried this, I was able to edit and disable the build agent which had been
lost, however the Queues page still showed the error.

Removing the bad agent from the build agent group also did not help.

If an agent is disabled, I don't think it should be contacted to see what is in its queue.

If it is going to be contacted, then the system needs to handle the case where it is not reachable.

>             Project: Continuum
>          Issue Type: Bug
>          Components: Distributed Builds
>    Affects Versions: 1.3.4
>            Reporter: Wendy Smoak
> When a build agent goes down unexpectedly, the system does not handle it gracefully.
> The Queues page (/displayQueues!display.action) shows Error Occurred org.apache.maven.continuum.ContinuumException:
Error retrieving projects currently preparing build in http://localhost:8181/continuum-buildagent/xmlrpc

> To reproduce, add 2 or more agents, force a bunch of builds, then stop one of the agents
without disabling it from the master.
> I notice  that the Build Agents page (/buildAgentList.action) still shows the agent as
Enabled=true, even though it is not responding.
> There should probably be some concept of the system automatically disabling an agent
that is not behaving correctly.  For now I'd be happy with the admin having to manually re-enable
it, but an auto-recovery feature might be a nice enhancement for later.
