Open Stack

Hi there,

we raised a bug https://bugs.launchpad.net/devstack/+bug/1193112 where the 
default configuration of swift in devstack interacts badly with keystone. We 
end up with the following exception iwth swift-proxy-server:

$ cd /opt/stack/swift && /opt/stack/swift/bin/swift-proxy-server 
/etc/swift/proxy-server.conf -v || touch "/opt/stack/status/stack/s-
proxy.failure"
proxy-server Starting keystone auth_token middleware
proxy-server Using /var/cache/swift as cache directory for signing certificate
proxy-server signing_dir mode is 0755 instead of 0700
proxy-server Starting the S3 Token Authentication component
Traceback (most recent call last):

__init__
    self.http_client_class = environment.httplib.HTTPConnection
AttributeError: 'NoneType' object has no attribute 'HTTPConnection'

I raised a work around here https://review.openstack.org/#/c/34207/ not in the 
hope that this code will get committed but in the hope that someone will see 
this and know what to do. That review is also a work around for anyone hit by 
this bug.

So if anyone knows what to do for this bug please help,

Michael
