[Bug 1717891] Re: Canonical-pike setup: cinder-api broken, fails to import _LE from i18n

[Corey Bryant]

Hi Akshay,

I'm unable to recreate this, unfortunately. Are there any more details
that you can share to help me reproduce this?

The following line of code in cinder/exception.py changed from this in ocata:
  from cinder.i18n import _, _LE
to this in pike:
  from cinder.i18n import _

And the following line of code in cinder/i18n.py existed in ocata but was removed in pike:
  _LE = _translators.log_error

I just tested an install of cinder-api from ocata, that I then upgraded
to pike, these files are updated correctly as described above.

Is there any chance that you had an upgrade from ocata->pike that
failed?

Thanks,
Corey

  When took a look at /usr/lib/python2.7/dist-packages/cinder/i18n.py,
  found that _LE is missing over here.

  import oslo_i18n as i18n

  DOMAIN = 'cinder'

  _translators = i18n.TranslatorFactory(domain=DOMAIN)

  # The primary translation function using the well-known name "_"
  _ = _translators.primary

  
  def enable_lazy(enable=True):
      return i18n.enable_lazy(enable)

  
  def translate(value, user_locale=None):
      return i18n.translate(value, user_locale)

  
  def get_available_languages():
      return i18n.get_available_languages(DOMAIN)
