This commit migrates Eventlet-specific components to the newly introduced backend system, isolating their implementation within the `oslo_service.backend.eventlet` module. The following changes have been made: - Eventlet Components: - Moved Eventlet-specific implementations of `service`, `loopingcall`, and `threadgroup` into `oslo_service/backend/eventlet/`. - Introduced an `EventletBackend` class with `get_service_components()` to expose these implementations dynamically. - Core Refactors: - Updated `service.py`, `loopingcall.py`, and `threadgroup.py` to retrieve Eventlet components via the backend system (`get_backend()`). - Backward Compatibility: - Ensured no changes to public APIs in `service.py`, `loopingcall.py`, and `threadgroup.py`. - Tests: Existing tests for Eventlet components remain applicable as the logic in the core files has not been modified. - Documentation: This change completes the migration of Eventlet-specific logic and prepares the codebase for alternative backend implementations in the future.

class SleepFixture(fixtures.Fixture):
|
|
"""A fixture for mocking the ``wait()`` within :doc:`loopingcall` events.
|
|
|
|
This exists so test cases can exercise code that uses :doc:`loopingcall`
|
|
without actually incurring wall clock time for sleeping.
|
|
|
|
The mock for the ``wait()`` is accessible via the fixture's ``mock_wait``
|
|
attribute.
|
|
|
|
.. note:: It is not recommended to assert specific arguments (i.e. timeout
|
|
values) to the mock, as this relies on the internals of
|
|
:doc:`loopingcall` not changing.
|
|
|
|
.. todo:: Figure out a way to make an enforceable contract allowing
|
|
verification of timeout values.
|
|
|
|
Example usage::
|
|
|
|
from oslo.service import fixture
|
|
...
|
|
class MyTest(...):
|
|
def setUp(self):
