Title:
servers.list, filtering on metadata doesn't work. unicode error
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
I'm trying to list servers by filtering on system_metadata or
metadata.
I should be able to do something like (looking into the code)
nclient.servers.list(search_opts={'system_metadata': {"some_value":
"some_key"}, 'all_tenants': 1})
But this dictionary gets turned into a unicode string. I get a 500
back from nova with the below stack trace in nova-api.
The offending code is in exact_filter in the db api. It is expecting a
list of dicts or a single dict when using system_metadata or metadata
key when searching. It looks like this used to work but now somewhere
higher up is ensuring this is a string.
