[jira] [Commented] (LIBCLOUD-1011) A unicode string is not an instance of basestring on Python 2.7.5

["Nigel B (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LIBCLOUD-1011?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16603799#comment-16603799 ] 

Nigel B commented on LIBCLOUD-1011:
-----------------------------------

[Line 152 in utils/py3|https://github.com/apache/libcloud/blob/trunk/libcloud/utils/py3.py#L152] seems to be the problem.

In Python2,

{{>>> basestring = unicode = str}}
{{>>> foo = u'unicode'}}
{{>>> isinstance(foo, basestring)}}
{{False}}

That is exactly the behavior that's the cause of this bug.
