* We're not translating LOG.debug, so change example. * Do not use locals() for translations. This synces the text as appropriate with the nova and cinder versions of this file. Change-Id: Ibcf16f1a93acaac0d06ccbd627233bfc62bc62ba

manila uses gettext so that user-facing strings such as log messages appear in the appropriate language in different locales.
To use gettext, make sure that the strings passed to the logger are
wrapped in a _() function call. For example:
LOG.info(_("block_device_mapping %s"), block_device_mapping)Do not use locals() for formatting messages because: 1.
It is not as clear as using explicit dicts. 2. It could produce hidden
errors during refactoring. 3. Changing the name of a variable causes a
change in the message. 4. It creates a lot of otherwise unused
variables.
If you do not follow the project conventions, your code may cause the LocalizationTestCase.test_multiple_positional_format_placeholders test to fail in manila/tests/test_localization.py.
The _() function is brought into the global scope by
doing:
from manila.openstack.common import gettextutils
gettextutils.install("manila")These lines are needed in any toplevel script before any manila modules are imported. If this code is missing, it may result in an error that looks like:
NameError: name '_' is not defined
