Current code in test_global_setup sets a non valid user_id and leaves it like that for the rest of the tests, which can lead to error: ValueError: A string is required in field user_id, not a _SentinelObject An easy way to reproduce this error is to create a file called fail.txt with the following content: cinderlib.tests.unit.test_cinderlib.TestCinderlib.test_global_setup cinderlib.tests.unit.test_serialization.TestSerialization.test_conn_to_and_from And then run from the tox virtual environment: stestr run --serial --load-list=fail.txt This patch fixes this issue by restoring the values after the test is run.

Cinder Library
Introduction
The Cinder Library, also known as cinderlib, is a Python library that leverages the Cinder project to provide an object oriented abstraction around Cinder's storage drivers to allow their usage directly without running any of the Cinder services or surrounding services, such as KeyStone, MySQL or RabbitMQ.
- Free software: Apache Software License 2.0
- Documentation: https://docs.openstack.org/cinderlib/latest/
The library is intended for developers who only need the basic CRUD functionality of the drivers and don't care for all the additional features Cinder provides such as quotas, replication, multi-tenancy, migrations, retyping, scheduling, backups, authorization, authentication, REST API, etc.
The library was originally created as an external project, so it didn't have the broad range of backend testing Cinder does, and only a limited number of drivers were validated at the time. Drivers should work out of the box, and we'll keep a list of drivers that have added the cinderlib functional tests to the driver gates confirming they work and ensuring they will keep working.
Features
- Use a Cinder driver without running a DBMS, Message broker, or Cinder service.
- Using multiple simultaneous drivers on the same application.
- Basic operations support:
- Create volume
- Delete volume
- Extend volume
- Clone volume
- Create snapshot
- Delete snapshot
- Create volume from snapshot
- Connect volume
- Disconnect volume
- Local attach
- Local detach
- Validate connector
- Extra Specs for specific backend functionality.
- Backend QoS
- Multi-pool support
- Metadata persistence plugins:
- Stateless: Caller stores JSON serialization.
- Database: Metadata is stored in a database: MySQL, PostgreSQL, SQLite...
- Custom plugin: Caller provides module to store Metadata and cinderlib calls it when necessary.
