Dear OpenStack Support Team, I'm a DEVOPS engineer who works for Zadara LTD. I hope this email finds you well. I am reaching out to inquire about the python-keystone package provided by OpenStack. Currently, our company utilizes Ubuntu Bionic (18.04.6) on our machines, and we have the python-keystone package installed and in use. However, we are now looking to upgrade to Python 3 and, consequently, need to transition from python-keystone to python3-keystone. In our codebase, we've integrated interfaces and APIs that rely on functions from the python-keystone Python library. However, as we transition to python3-keystone, I've identified several deprecated functions and modules which are no longer supported within the new package. To address this, I'm reaching out for assistance in finding suitable replacements within the new package. The deprecated functions/modules that require replacement (no longer supported by the new package) are: 1. keystone.common.dependency.resolve_future_dependencies() 2. keystone.auth.controllers.Auth.validate_token() 3. keystone.contrib.ec2.controllers.Ec2ControllerV3 - specifically: create_credential(), delete_credential() and get_credential() 4. keystone.resource.controllers.ProjectV3 - specifically: get_project, update_project, delete_project, create_project. 5. keystone.assignment.controllers 6. keystone.token.persistence.PersistenceManager Any guidance or assistance you can provide on this matter would be greatly appreciated. Thank you for your attention to this inquiry, and I look forward to hearing from you soon.
