Sean Mooney f3d48000b1 Add autopep8 to tox and pre-commit
autopep8 is a code formating tool that makes python code pep8
compliant without changing everything. Unlike black it will
not radically change all code and the primary change to the
existing codebase is adding a new line after class level doc strings.

This change adds a new tox autopep8 env to manually run it on your
code before you submit a patch, it also adds autopep8 to pre-commit
so if you use pre-commit it will do it for you automatically.

This change runs autopep8 in diff mode with --exit-code in the pep8
tox env so it will fail if autopep8 would modify your code if run
in in-place mode. This allows use to gate on autopep8 not modifying
patches that are submited. This will ensure authorship of patches is
maintianed.

The intent of this change is to save the large amount of time we spend
on ensuring style guidlines are followed automatically to make it
simpler for both new and old contibutors to work on nova and save
time and effort for all involved.

Stephen Finucane c269285568 tests: Move remaining non-libvirt fixtures
Move these to the central place. There's a large amount of test damage
but it's pretty trivial.

Stephen Finucane cc45581a18 functional: Add and use 'GlanceFixture'
This rather beefy (but also quite simple) patch replaces the
'stub_out_image_service' call and associated cleanup in all functional
tests with a new 'GlanceFixture', based on the old 'FakeImageService'.
The use of a fixture means we don't have to worry about teardown and
allows us to stub Glance in the same manners as Cinder, Neutron,
Placement etc.

Unit test cleanup is handled in a later patch.

Stephen Finucane 458d37fceb functional: Add unified '_build_server' helper function
'_IntegratedTestBase' has subclassed 'InstanceHelperMixin' since change
I0d21cb94c932e6e556eca964c57868c705b2d120, which means both now provide
a '_build_minimal_create_server_request' function. However, only
'_IntegratedTestBase' provides a '_build_server' function. The
'_build_minimal_create_server_request' and '_build_server' functions do
pretty much the same thing but there are some differences. Combine these
under the '_build_server' alias.

Stephen Finucane 7ae1a10913 functional: Remove 'api' parameter
Pretty much every test case in 'nova.tests.functional' defines an 'api'
attribute, and many define an 'admin_api' attribute. We can pull these
from the class rather than explicitly passing them to helpers. Rework
things so this happens.

Note that the bulk of the changes here are in the
'nova/tests/functional/integrated_helpers.py' file. The rest of the
changes were auto-generated using the following script (my sed-fu is
non-existent):

  $ cd nova/tests/functional
  $ python3
  >>> import glob
  >>> import re
  >>> pattern = r'_state_change\((\n\s+)?self\.(admin_)?api,\s+'
  >>> replace = r'_state_change(\1'
  >>> for path in glob.glob('*.py') + glob.glob('*/*.py'):
  ...     with open(path) as fh:
  ...         data = fh.read()
  ...     new = re.sub(pattern, replace, data, flags=re.MULTILINE)
  ...     if new != data:
  ...         with open(path, 'w') as fh:
  ...             fh.write(new)
  ...
  >>> quit()

(ditto for the other substitutions)

Some manual fixups were required after, which pre-commit highlighted :)

Balazs Gibizer 60b097a5ef Move HostNameWeigher to a common fixture
Multiple functional tests used its own copy-pasted implementation of a
weigher to make the scheduling deterministic based on host names.

This patch moves the HostNameWeigher implementation to a common place
and adds a fixtures to set up the weigher in the conf.

Balazs Gibizer b5666fb492 Remove global state from the FakeDriver
The virt driver FakeDriver used in both the functional and in the unit
test used a global state to configure the host and node names the driver
reports. This was hard to use when more then one compute service is started.
Also global state is dangerous.

It turned out that only a set of unit tests are using multiple nodes per
compute the rest of the tests can simply use host=<hostname>,
nodes=[<hostname>] setup.

So this removes the global state.

Takashi NATSUME bda4ae3884 Remove duplicate cleanup in functional tests
It is not necessary to call the following statement multiple times in
some functional tests.

self.addCleanup(fake.restore_nodes)

So remove duplicate calls in the tests.

Chris Dent 787bb33606 Use external placement in functional tests
Adjust the fixtures used by the functional tests so they
use placement database and web fixtures defined by placement
code. To avoid making redundant changes, the solely placement-
related unit and functional tests are removed, but the placement
code itself is not (yet).

openstack-placement is required by the functional tests. It is not
added to test-requirements as we do not want unit tests to depend
on placement in any way, and we enforce this by not having placement
in the test env.

The concept of tox-siblings is used to ensure that the
placement requirement will be satisfied correctly if there is a
depends-on. To make this happen, the functional jobs defined in
.zuul.yaml are updated to require openstack/placement.

tox.ini has to be updated to use a envdir that is the same
name as job. Otherwise the tox siblings role in ansible cannot work.

The handling of the placement fixtures is moved out of nova/test.py
into the functional tests that actually use it because we do not
want unit tests (which get the base test class out of test.py) to
have anything to do with placement. This requires adjusting some
test files to use absolute import.

Similarly, a test of the comparison function for the api samples tests
is moved into functional, because it depends on placement functionality,

TestUpgradeCheckResourceProviders in unit.cmd.test_status is moved into
a new test file: nova/tests/functional/test_nova_status.py. This is done
because it requires the PlacementFixture, which is only available to
functional tests. A MonkeyPatch is required in the test to make sure that
the right context managers are used at the right time in the command
itself (otherwise some tables do no exist). In the test itself, to avoid
speaking directly to the placement database, which would require
manipulating the RequestContext objects, resource providers are now
created over the API.

Matt Riedemann 4afa8c2b97 Fix race fail in test_resize_with_reschedule_then_live_migrate
The assertion in the test that the migration status is 'completed'
is flawed in that it assumes when the instance status is 'ACTIVE'
the migration is completed, which isn't True, since the instance
status gets changed before the migration is completed, but they are
very close in time so there is a race, which is how this test slipped
by. This fixes the issue by polling the migration status until it
is actually completed or we timeout.

Matt Riedemann 6647f11dc1 Don't persist RequestSpec.retry
During a resize, the RequestSpec.flavor is updated
to the new flavor. If the resize failed on one host
and was rescheduled, the RequestSpec.retry is updated
for that failed host and mistakenly persisted, which
can affect later move operations, like if an admin
targets one of those previously failed hosts for a
live migration or evacuate operation.

This change fixes the problem by not ever persisting
the RequestSpec.retry field to the database, since
retries are per-request/operation and not something
that needs to be persisted.

Alternative to this, we could reset the retry field
in the RequestSpec.reset_forced_destinations method
but that would be slightly overloading the meaning
of that method, and the approach taken in this patch
is arguably cleaner since retries shouldn't ever be
persisted. It should be noted, however, that one
advantage to resetting the 'retry' field in the
RequestSpec.reset_forced_destinations method would
be to avoid this issue for any existing DB entries
that have this problem.

The related functional regression test is updated
to show the bug is now fixed.

Matt Riedemann 89448bea57 Add regression test for persisted RequestSpec.retry from failed resize
Commit 74ab427d47 in Newton added
code to persist changes to the RequestSpec during a resize since
the flavor changes.

That change inadvertantly also persisted any failed hosts during
the resize that are stored in the RequestSpec.retry field during
a reschedule.

The problem is that later those persisted failed hosts are rejected
by the RetryFilter, which can be confusing if an admin is trying
to live migrate or evacate the instance to one of those specific
hosts.

This adds a functional regression test to show the failure, which
will be fixed in a separate change that then modifies the assertions.
