-----------------------------------------------------------------
Ran into this issue, and it got the better of my curiosity. The cause is that
libcloud doesn't have python 2 compatible \_\_repr\_\_ methods. In python 2 the
{{repr}} builtin expects a \_\_repr\_\_ method which returns an ascii string
(or something coercible to an ascii string). It's required because {{repr}}
will translate the result of {{X.\_\_repr\_\_()}} to ascii.
In the case of
[Node.__repr|https://github.com/apache/libcloud/blob/408caa9c95a197578baede0a5a1476e9201486e7/libcloud/compute/base.py#L260-L266]__,
if the node's name contains characters outside of ascii, then whenever
{{repr(node)}} is called the unicode string returned from {{repr}} will fail to
be encoded as ascii.
It looks like in python 3 the opposite is true, {{repr}} should return unicode
strings.
The builtin {{str}} has all the same caveats.
This can also easily be replicated by stubbing out a simple class:
{code:java}
class Foo:
def __repr__(self):
return u'\xe0'
> repr(Foo())
> str(Foo())
{code}

> Project: Libcloud
> Issue Type: Bug
> Environment: ubuntu 12.04, python 2.7, opennebula 3.8
> Reporter: Guillaume ZITTA
> Priority: Critical
> Attachments: debug.log, test_utf.py, utf-8_python2.patch,
> utf-8_python2_xml.workaround.patch
>
>
> We have an opennebula with French accents in networks names.
> Listing networks leads to a crash because of these accents in the XML
> response of the cloud.
