This is a large and invasive change to the underlying guts. Most casual
use should not notice a difference, but advanced users, especially those
using the Profile or Authenticator interfaces or making use of pluggable
providers will be broken.
The overall intent is to align directly on top of the mechanisms that
came from os-client-config for config and to use keystoneauth1's Adapter
interface to make use of the canonical implementations of such things as
service and version discovery. The end goal is that openstacksdk
provides the REST interaction layer for python-openstackclient, shade,
Ansible and nodepool.
Replace profile with openstack.config
os-client-config is used by shade and python-openstackclient to read
and process configuration. openstacksdk also can use the
os-client-config interface, but translates it internally into the
Profile object. As os-client-config has been injested into
openstack.config, remove Profile and just use the config classes.
Make proxy subclass of adapter
This gives every service a generic passthrough for REST calls, which
means we can map unknown service-type values to a generic proxy.
Strip endpoint_filter
We're passing Adapters around, not sessions. Doing so means that
self.service and endpoint_filter have become unnecessary.
Rename _Request.uri to _Request.url
This is a stepping-stone to replacing _Request with requests.Request and
using requests.Session.prepare_request inside of _prepare_request.
Rename service proxy instances to match their official service-type.
Aliases are kept for the old versions, but make the canonical versions
match the official name.
Rename bare_metal to baremetal
Rename cluster to clustering
Rename block_store to block_storage
Rename telemetry to meter
Create generic proxies for all services in STA
Every service listed in service types authority is an OpenStack service.
Even if we don't know about it in SDK, we should at the very least have
a low-level Adapter for it so that people can use REST calls while
waiting on the SDK to add higher-level constructs.
The pypy jobs are happily green. Run them as voting rather than
non-voting.
Add syntatic sugar alias for making connections
Typing:
import openstack.connection
conn = openstack.connection.Connection(cloud='example')
is annoying. This allows:
import openstack
conn = openstack.connect(cloud='example')
Use task_manager and Adapter from shade
As a stepping-stone towards shade and sdk codepaths being rationalized,
we need to get SDK using the Adapter from shade that submits requests
into the TaskManager. For normal operation this is a passthrough/no-op
sort of thing, but it's essential for high-volume consumers such as
nodepool.
This exposes a bunch of places in tests where we're mocking a bit too
deeply. We should go back through and fix all of those via
requests_mock, but that's WAY too much for today.
This was a 'for later' task, but it turns out that the move to Adapter
was causing exceptions to be thrown that were not the exceptions that
were intended to be caught in the SDK layer, which was causing
functional tests of things like GET operations to fail. So it became a
today task.
