existing_users context cannot fetch 'tenant' and 'user' details from cloud deployment

[Chandidas Gharami]

'Existing User' context does not work properly in latest rally. It cannot fetch 'tenant' and 'user' details from cloud deployment.

Rally Version User to test:

[root@jb eu_issue]# rally --version
0.4.1~dev254

Here I captured the context it created in one sample run.

2016-07-12 07:28:49.725 31446 INFO rally.plugins.eu_issue.eu_test [-] context : {'task': <rally.common.objects.task.Task object at 0x4619390>, 'admin': {'credential': <rally.common.objects.credential.Credential object at 0x46193d0>}, 'iteration': 0L, 'user': {'credential': <rally.common.objects.credential.Credential object at 0x4619550>, 'id': None, 'tenant_id': None}, 'scenario_name': 'ExistingUserTest.log_existing_users', 'config': {'cleanup': [], 'existing_users': [{'username': 'pre_u_1', 'endpoint': None, 'region_name': 'depl-01', 'https_insecure': True, 'permission': 'user', 'tenant_name': 'pre_t_1', 'user_domain_name': None, 'https_cacert': 'ca-chaincert.pem', 'domain_name': None, 'admin_domain_name': 'Default', 'endpoint_type': 'public', 'auth_url': 'https://keystone.service.os:5000/v2.0/', 'password': 'dump1', 'project_domain_name': None}, {'username': 'pre_u_2', 'endpoint': None, 'region_name': 'depl-01', 'https_insecure': True, 'permission': 'user', 'tenant_name': 'pre_t_2', 'user_domain_name': None, 'https_cacert': 'ca-chaincert.pem', 'domain_name': None, 'admin_domain_name': 'Default', 'endpoint_type': 'public', 'auth_url': 'https://keystone.service.os:5000/v2.0/', 'password': 'dump1', 'project_domain_name': None}, {'username': 'pre_u_3', 'endpoint': None, 'region_name': 'depl-01', 'https_insecure': True, 'permission': 'user', 'tenant_name': 'pre_t_3', 'user_domain_name': None, 'https_cacert': 'ca-chaincert.pem', 'domain_name': None, 'admin_domain_name': 'Default', 'endpoint_type': 'public', 'auth_url': 'https://keystone.service.os:5000/v2.0/', 'password': 'dump1', 'project_domain_name': None}]}, 'tenant': {'id': None, 'name': 'pre_t_1'}}

User and Tenant information have below values respectively:
'user': {'credential': <rally.common.objects.credential.Credential object at 0x4619550>, 'id': None, 'tenant_id': None}
'tenant': {'id': None, 'name': 'pre_t_1'}

This shows, current existing_users context cannot retrieve required values from cloud deployment.

However, the scenario can run for all the iterations configured with this 'user' and 'tenant' values in all iterations.

Attached a simple scenario which is used to experiment this.

With the latest code, the 'tenant_id' field is getting populated with right value and as a result 'tenant-context' is also getting populated with all the configured user. This would be sufficient for distribution of tenants across scenario runs.

However, user 'id' field in user's list is still None. This might not be an issue as Credential object of the user is correctly populated. But if user id is used later in any part of a scenario, it will be None.

Working to fix the 'user id' issue.
