KeyError: u'memory_mb_limit' in nova.po

[Lance Bragstad]

Discovered Key Error while trying to boot instances. The following code in nova.po at line 3743:

#: nova/compute/resource_tracker.py:168
#, fuzzy, python-format
msgid ""
"Attempting claim: memory %(memory_mb)d MB, disk %(disk_gb)d GB, VCPUs "
"%(vcpus)d"
msgstr ""
"Attempting claim: memory %(memory_mb)d MB, disk %(disk_gb)d GB, mem limit"
" %(memory_mb_limit)s"

https://github.com/openstack/nova/blob/master/nova/locale/en_US/LC_MESSAGES/nova.po#L3740

Produces the following error:

2013-01-18 15:56:22.796 ERROR nova.compute.manager [req-d7b141a1-f91b-4615-b344-518092b618dd 65836e9a4c594e7a929bad924d411b51 8712bc7ce33d452aba3c810e3825b63f] [instance: efa7e6ca-a66e-4b42-b76e-971d1868c8d2] Error: ['Traceback (most recent call last):\n', ' File "/usr/lib/python2.6/site-packages/nova/compute/manager.py", line 680, in _run_instance\n with rt.instance_claim(context, instance, limits):\n', ' File "/usr/lib/python2.6/site-packages/nova/openstack/common/lockutils.py", line 234, in inner\n retval = f(*args, **kwargs)\n', ' File "/usr/lib/python2.6/site-packages/nova/compute/resource_tracker.py", line 102, in instance_claim\n if claim.test(self.compute_node, limits):\n', ' File "/usr/lib/python2.6/site-packages/nova/compute/claims.py", line 120, in test\n LOG.audit(msg % params, instance=self.instance)\n', "KeyError: u'memory_mb_limit'\n"]

The string message can't be translated because it is trying to reference 'memory_mb_limit' as the key, which is not found.

 the ./nova/locale/en_US/LC_MESSAGES/nova.po has a bad msgstr for at least one msgid - what's the process for updating the .po files? do we start by running extract_messages again?

    Update en_US message translations.

    Fixes bug 1101587.

    * nova/locale/en_US/LC_MESSAGES/nova.po: This "translation" was
    woefully outdated, causing KeyError exceptions under a number of
    circumstances for users of this particular locale when format
    strings wound up containing incorrect substitution variables. This
    change attempts to sync up the msgstr entries to match msgid given
    this is the source language for the pot file. I did not see any
    obvious instances where en_US should differ from C locale for these.
