This applies to the SQLAlchemy Cinder backend. Reproduced in icehouse, but looks like it's present in master as well.
Reproduce:
- start an instance
- take a snapshot, give it a non-ASCII name (mine was "ceilometer-dev-β")
- create a volume from the resulting image
Observed behaviour: volume transitions from "Downloading" to "Error"; checking the cinder log results in the attached stacktrace. The same process works fine without non-ASCII characters in the image name. I infer that this is not expected from this[0] wiki page.
Looking in cinder/db/sqlalchemy/api.py, I see this: https://github.com/openstack/cinder/blob/master/cinder/db/sqlalchemy/api.py#L2488
which looks like it could benefit from using the safe encoding functions in openstack.common.strutils, but these aren't used elsewhere in the module and I'm unsure if there's a reason for that or not (rather new to Openstack at the moment). Happy to submit a patch if I haven't misunderstood anything.
