Subject [jira] [Created] (LIBCLOUD-547) linode labels - 1 to 48 chars
Date Tue, 29 Apr 2014 12:32:14 GMT
Gary Wilson created LIBCLOUD-547:
------------------------------------

             Summary: linode labels - 1 to 48 chars
                 Key: LIBCLOUD-547
                 URL: https://issues.apache.org/jira/browse/LIBCLOUD-547
             Project: Libcloud
          Issue Type: Bug
          Components: Compute
    Affects Versions: 0.14.0-beta3
            Reporter: Gary Wilson


The labels generated in libcloud/compute/drivers/linode.py are limited in length, however
seeing as the name is using the node name which is a hostname and can be up to 63 characters
as per RFC 1034, the generated labels can result in a string longer than the allowed 48 characters.

In this instance the name was zpf-watcher-dev-2-96g-luk1

[zpf-watcher-dev-2-96g-luk1] Configuration Profile = 51 chars

Perhaps the linode["id"] could be used instead of name as the name could be longer than 48
chars

        # Labels
        label = {
            "lconfig": "[%s] Configuration Profile" % name,
            "lroot": "[%s] %s Disk Image" % (name, image.name),
            "lswap": "[%s] Swap Space" % name
        }
        for what in ["lconfig", "lroot", "lswap"]:
            if what in kwargs:
                label[what] = kwargs[what]
