Our current APIVersion object has an is_null method to check when the
version instance is null (major=0 and minor=0).
While this works it is not very pythonic, since you have to write
expressions such as:
if not min_version and not max_version:
return True
elif ((min_version and max_version) and
max_version.is_null() and min_version.is_null()):
return True
This patch removes the is_null method and instead implements the truth
value testing to simplify expressions and make code more pythonic.
So previous code would just look like:
if not min_version and not max_version:
return True
Because this will work with min_version being None or being an
APIVersion instance with major=0 and minor=0.

Python bindings to the OpenStack Cinder API
This is a client for the OpenStack Cinder API. There's a Python API
(the cinderclient module), and a command-line script
(cinder). Each implements 100% of the OpenStack Cinder
API.
See the OpenStack
CLI Reference for information on how to use the cinder
command-line tool. You may also want to look at the OpenStack API
documentation.
The project is hosted on Launchpad, where bugs can be filed. The code is hosted on OpenStack. Patches must be submitted using Gerrit.
This code is a fork of Jacobian's python-cloudservers. If you need API support for the Rackspace API solely or the BSD license, you should use that repository. python-cinderclient is licensed under the Apache License like the rest of OpenStack.

Command-line API
Installing this package gets you a shell command,
cinder, that you can use to interact with any Rackspace
compatible API (including OpenStack).
You'll need to provide your OpenStack username and password. You can
do this with the --os-username, --os-password
and --os-tenant-name params, but it's easier to just set
them as environment variables:
export OS_USERNAME=openstack
export OS_PASSWORD=yadayada
export OS_TENANT_NAME=myprojectYou will also need to define the authentication url with
--os-auth-url and the version of the API with
--os-volume-api-version. Or set them as environment
variables as well:
export OS_AUTH_URL=http://example.com:8774/v1.1/
export OS_VOLUME_API_VERSION=1If you are using Keystone, you need to set the OS_AUTH_URL to the keystone endpoint:
export OS_AUTH_URL=http://example.com:5000/v2.0/Since Keystone can return multiple regions in the Service Catalog,
you can specify the one you want with --os-region-name (or
export OS_REGION_NAME). It defaults to the first in the
list returned.
You'll find complete documentation on the shell by running
cinder help:

There's also a complete Python API, but it has not yet been documented.
Quick-start using keystone:
# use v2.0 auth with http://example.com:5000/v2.0/
>>> from cinderclient.v1 import client
>>> nt = client.Client(USER, PASS, TENANT, AUTH_URL, service_type="volume")
>>> nt.volumes.list()
