Client fails with global name '_' is not defined error when env[OS_USERNAME] is not exported

[Michal Dulko]

Due to latest changes to support Keystone v3 API client produces strange error when environment variables with OpenStack credentials are not exported:

mdulko@gklab-044-100:~/devstack$ glance image-list
global name '_' is not defined
mdulko@gklab-044-100:~/devstack$ source openrc
mdulko@gklab-044-100:~/devstack$ glance image-list

As of Dec 24 2014 i have same issue.
If OS env vars not set i have the same error.
You can get rid of it by sourcing the env file.

glancerc
export OS_TENANT_NAME=service
export OS_USERNAME=glance
export OS_PASSWORD=pass
export OS_AUTH_URL=http://controller:5000/v2.0

    Unit tests covering missing username or password

    After fixing message displayed when client is executed without
    required environment variables exported (OS_USERNAME, OS_PASSWORD,
    OS_PROJECT_NAME, OS_AUTH_URL) regression tests should be added. I've
    also fixed an issue causing tests using make_env method to always use
    FAKE_V2_ENV, even in ShellTestWithKeystoneV3Auth.
