_ seems to have gone missing

[Joshua Harlow]

It seems like builds are now failing due to the following.

>>> from cinder.volume import utils as volume_utils
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "cinder/volume/__init__.py", line 29, in <module>

  File "cinder/exception.py", line 92, in CinderException
    message = _("An unknown exception occurred.")
NameError: name '_' is not defined

Has '_' been moved somewhere by a dependent project.

It could be caused by commit 7cfb0388fff7a1282141ed50b9b6d6cf65af55a1

Remove gettext.install() from cinder/__init__.py

[John Griffith (john-griffith)]

from openstack.common.gettextutils import _

[John Griffith (john-griffith)]

BTW, I marked as invalid as I haven't seen this or reproduced it and I *think* the patch set you were running into this on you found the issue and addressed it. If I'm wrong here feel free to re-open or ping me.

@ John Griffith
I am confused why there is no "from openstack.common.gettextutils import _" in cinder/exception.py ?

It will report this Error when I use sphinx to build cinder doc. This Error showed up in the following four files:
*****************************************
   cinder/cinder/exception.py
    cinder/cinder/policy.py
    cinder/cinder/common/config.py
    cinder/cinder/api/v1/limits.py
 *****************************************
Missing "from openstack.common.gettextutils import _" in these files caused this Error. Is this not a bug or a defect?

[wangchy (wangchy)]

gettext.install() was removed from cinder/__init__.py with this commit https://review.openstack.org/#/c/28543/2.
But this is needed for doc build with sphinx because the toplevel script is not any of the scripts under path "bin", but cinder/api/openstack/__init__.py. Without gettext.install() invoked in cinder/api/openstack/__init__.py, sphinx-build will fail and no docs on APIs can be generated. I thinks the cases are the same withe other components including nova, neutron, etc.

[wangchy (wangchy)]

I changed the status to new because this should be an issue for it introduces errors in doc build, although it does not affect runtime functions. It should not be changed in invalid .

    Provide gettext _ in missing locations

    A while back a change was merged that moved
    our shortcut for gettext out of __init__
    (change here: If4125d6bcbde63df95de129ac5c83b4a6d6f130a)

    This worked out fine for the most part but broke the sphinx doc
    builder for a number of files. This patch just adds the proper
    import to each of these files to get the builder working correctly
    again.
