some Glance-specific stuff. README.rst shows what
WILL be the way to do things, not what is currently coded :)

Glance Style Commandments
=========================
- Step 1: Read http://www.python.org/dev/peps/pep-0008/
- Step 2: Read http://www.python.org/dev/peps/pep-0008/ again
- Step 3: Read on
General
-------
- Put two newlines between top-level code (funcs, classes, etc)
- Put one newline between methods in classes and anywhere else
- Do not write "except:", use "except Exception:" at the very least
- Include your name with TODOs as in "#TODO(termie)"
- Do not name anything the same name as a built-in or reserved word
Imports
-------
- Do not make relative imports
- Order your imports by the full module path
- Organize your imports according to the following template
Example::
# vim: tabstop=4 shiftwidth=4 softtabstop=4
{{stdlib imports in human alphabetical order}}
\n
{{third-party lib imports in human alphabetical order}}
\n
{{glance imports in human alphabetical order}}
\n
\n
{{begin your code}}
Human Alphabetical Order Examples
---------------------------------
Example::
import httplib
import logging
import random
import StringIO
import time
import unittest
import eventlet
import webob.exc
import glance.api.middleware
from glance.api import images
from glance.auth import users
import glance.common
from glance.endpoint import cloud
from glance import test
Docstrings
----------
Docstrings are required for all functions and methods.
Docstrings should ONLY use triple-double-quotes (``"""``)
Single-line docstrings should NEVER have extraneous whitespace
between enclosing triple-double-quotes.
**INCORRECT** ::
""" There is some whitespace between the enclosing quotes :( """
**CORRECT** ::
"""There is no whitespace between the enclosing quotes :)"""
Docstrings that span more than one line should look like this:
Example::
"""
Start the docstring on the line following the opening triple-double-quote
If you are going to describe parameters and return values, use Sphinx, the
appropriate syntax is as follows.
:param foo: the foo parameter
:param bar: the bar parameter
:returns: return_type -- description of the return value
:returns: description of the return value
:raises: AttributeError, KeyError
"""
**DO NOT** leave an extra newline before the closing triple-double-quote.
Dictionaries/Lists
------------------
If a dictionary (dict) or list object is longer than 80 characters, its items
should be split with newlines. Embedded iterables should have their items
indented. Additionally, the last item in the dictionary should have a trailing
comma. This increases readability and simplifies future diffs.
Example::
my_dictionary = {
"image": {
"name": "Just a Snapshot",
"size": 2749573,
"properties": {
"user_id": 12,
"arch": "x86_64",
},
"things": [
"thing_one",
"thing_two",
],
"status": "ACTIVE",
},
}
Calling Methods
---------------
Calls to methods 80 characters or longer should format each argument with
newlines. This is not a requirement, but a guideline::
unnecessarily_long_function_name('string one',
'string two',
kwarg1=constants.ACTIVE,
kwarg2=['a', 'b', 'c'])
Rather than constructing parameters inline, it is better to break things up::
list_of_strings = [
'what_a_long_string',
'not as long',
]
dict_of_numbers = {
'one': 1,
'two': 2,
'twenty four': 24,
}
object_one.call_a_method('string three',
'string four',
kwarg1=list_of_strings,
kwarg2=dict_of_numbers)
Internationalization (i18n) Strings
-----------------------------------
In order to support multiple languages, we have a mechanism to support
automatic translations of exception and log strings.
Example::
msg = _("An error occurred")
raise HTTPBadRequest(explanation=msg)
If you have a variable to place within the string, first internationalize the
template string then do the replacement.
Example::
msg = _("Missing parameter: %s") % ("flavor",)
LOG.error(msg)
If you have multiple variables to place in the string, use keyword parameters.
This helps our translators reorder parameters when needed.
Example::
msg = _("The server with id %(s_id)s has no key %(m_key)s")
LOG.error(msg % {"s_id": "1234", "m_key": "imageId"})
Creating Unit Tests
-------------------
For every new feature, unit tests should be created that both test and
(implicitly) document the usage of said feature. If submitting a patch for a
bug that had no unit test, a new passing unit test should be added. If a
submitted bug fix does have a unit test, be sure to add a new one that fails
without the patch and passes with the patch.

Python bindings to the OpenStack Glance API
=============================================
This is a client for the OpenStack Glance API. There's a Python API (the
``glanceclient`` module), and a command-line script (``glance``). The
Glance 2.0 API is still a moving target, so this module will remain in
"Beta" status until the API is finalized and fully implemented.
Development takes place via the usual OpenStack processes as outlined in
the `OpenStack wiki`_. The master repository is on GitHub__.
__ http://wiki.openstack.org/HowToContribute
__ http://github.com/openstack/python-glanceclient
This code a fork of `Rackspace's python-novaclient`__ which is in turn a fork of
`Jacobian's python-cloudservers`__. The python-glanceclient is licensed under
the Apache License like the rest of OpenStack.
__ http://github.com/rackspace/python-novaclient
__ http://github.com/jacobian/python-cloudservers
.. contents:: Contents:

Python API
----------
By way of a quick-start::
# use v2.0 auth with http://example.com:5000/v2.0")
>>> from glanceclient.v2_0 import client
>>> glance = client.Client(username=USERNAME, password=PASSWORD, tenant_name=TENANT, auth_url=KEYSTONE_URL)
>>> glance.images.list()
>>> image = glance.images.create(name="My Test Image")
>>> print image.status
'queued'
>>> image.upload(open('/tmp/myimage.iso', 'rb'))
>>> print image.status
'active'
>>> image_file = image.image_file
>>> with open('/tmp/copyimage.iso', 'wb') as f:
for chunk in image_file:
f.write(chunk)
>>> image.delete()
Command-line API
----------------
Installing this package gets you a command-line tool, ``glance``, that you
can use to interact with Glance's Identity API.
You'll need to provide your OpenStack tenant, username and password. You can do this
with the ``tenant_name``, ``--username`` and ``--password`` params, but it's
easier to just set them as environment variables::
export OS_TENANT_NAME=project
export OS_USERNAME=user
export OS_PASSWORD=pass
You will also need to define the authentication url with ``--auth_url`` and the
version of the API with ``--identity_api_version``. Or set them as an environment
variables as well::
export OS_AUTH_URL=http://example.com:5000/v2.0
export OS_IDENTITY_API_VERSION=2.0
Since the Identity service that Glance uses can return multiple regional image
endpoints in the Service Catalog, you can specify the one you want with
``--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
``glance help``::
usage: glance [--username USERNAME] [--password PASSWORD]
[--tenant_name TENANT_NAME | --tenant_id TENANT_ID]
[--auth_url AUTH_URL] [--region_name REGION_NAME]
[--identity_api_version IDENTITY_API_VERSION]
<subcommand> ...
Command-line interface to the OpenStack Identity API.
Positional arguments:
<subcommand>
catalog List all image services in service catalog
image-create Create new image
image-delete Delete image
image-list List images
image-update Update image's name and other properties
image-upload Upload an image file
image-download Download an image file
help Display help about this program or one of its
subcommands.
Optional arguments:
--username USERNAME Defaults to env[OS_USERNAME]
--password PASSWORD Defaults to env[OS_PASSWORD]
--tenant_name TENANT_NAME
Defaults to env[OS_TENANT_NAME]
--tenant_id TENANT_ID
Defaults to env[OS_TENANT_ID]
--auth_url AUTH_URL Defaults to env[OS_AUTH_URL]
--region_name REGION_NAME
Defaults to env[OS_REGION_NAME]
--identity_api_version IDENTITY_API_VERSION
Defaults to env[OS_IDENTITY_API_VERSION] or 2.0
See "glance help COMMAND" for help on a specific command.
