The Nova Compute API returns a series of headers as a result of create operation. The location header is being returned as a unicode value which is not compliant with the RFC for HTTP.
I haven't figured out yet whether this is a global thing or specific to something more localised.
While not a problem when running with nova-api services directly the problem manifests itself if a user was to front the API with something that requires rfc compliant headers to be returned, such as Apache.
Eg execute: nova image-create 69136d40-8de0-4a63-b03a-16543d390c8e test-snap-20131004-10
Response:
ERROR: <attribute 'message' of 'exceptions.BaseException' objects> (HTTP 500)
Apache's error log shows:
[Fri Oct 04 14:08:42 2013] [error] [client 192.168.4.63] mod_wsgi (pid=20280): Exception occurred processing WSGI script '/etc/apache2/wsgi/nova-api-os-compute'.
[Fri Oct 04 14:08:42 2013] [error] [client 192.168.4.63] TypeError: expected byte string object for header value, value of type unicode found
The actual image-create ends up being successful, even though the client receives a HTTP 500 response.
Environment: Openstack Grizzly on Ubuntu with package level 2013.1.3 |

While this is the same result as https://bugs.launchpad.net/nova/+bug/938114 It appears to me that this is more localised. |
