[dev] [jira] [Commented] (LIBCLOUD-105) "list_nodes" on Eucalytus forces
a "500 Internal Server Error"
[ https://issues.apache.org/jira/browse/LIBCLOUD-105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13080590#comment-13080590 ]
Rick Bross commented on LIBCLOUD-105:
-------------------------------------
Note that this issue only manifests itself if there is a single instance in the node list in the "Running" state. This seems to point to an issue in the "shortcut" filter code in ec2.py:
if len(nodes) == 1:
params.update({
'Filter.0.Name': 'instance-id',
'Filter.0.Value.0': nodes[0].id
})

> Key: LIBCLOUD-105
> URL: https://issues.apache.org/jira/browse/LIBCLOUD-105
> Project: Libcloud
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.5.2
> Environment: Eucalyptus 1.6, Python 2.7.1, Ubuntu 11.04
> Reporter: Rick Bross
> Fix For: 0.5.2
>
>
> Note that in the debug log below, when calling "list_nodes" the "DescribeInstances" call is successful. But "list_nodes" then goes on to do an additional (and unnecessary?) "DescribeAddresse" call which causes the error.

> CODE:
> logfile = open('/home/user/lc.log', "a")
> enable_debug(logfile)
> EC2_ACCESS_ID = 'WKy3rMzOWPouVOxK1p3Ar1C2uRBwa2FBXnCw'
> EC2_SECRET_KEY = 'QhVkQMPZXd6i6qVH8tkIEqGmdVGkk1cuzJEgg'
> EUCDriver = get_driver(Provider.EUCALYPTUS)
> conn = EUCDriver(EC2_ACCESS_ID, secret=EC2_SECRET_KEY, host="192.168.0.170", secure=False, port=8773, path="/services/Eucalyptus")
> # This should iterate over driver types and create a generic list of nodes with required fields
> nodes = []
> nodes += conn.list_nodes()
