I agree that it's somewhat unfortunate tripleo is using a different
default region name than devstack, but at the same time I wouldn't
expect to be able to use a devstack rc file to talk to a tripleo cloud.
 Tripleo has its own rc files to be used for that.

The general standard in OpenStack has been case sensitivity. There are
performance and security implications on case insensitive environments.

It just sounds like tripleo is using a bad default here, and that's what
should be addressed.

That’s true, but the OP was asking whether the region name should be case 
sensitive or not. 

I think it probably makes sense that regionOne should be the same as RegionONE, 
or RegionOne.

Both glance/nova python client libraries allows users to specify region
name (see http://docs.openstack.org/user-guide/content/sdk_auth_nova.html).
So, you are free to metion any region you want.

[openstack-dev] [Keystone] Should region name be case insensitive?

2015-01-07 Thread Zhou, Zhenzan 
Hi,

I meet such an issue when using glance/nova client deployed with Devstack to 
talk with a cloud deployed with TripleO:

[minicloud@minicloud allinone]$ glance image-list
public endpoint for image service in RegionOne region not found

The reason is that Devstack uses “RegionOne” as default but TripleO uses 
“regionOne” and
keystoneclient/service_catalog.py: get_endpoints() does a case sensitive string 
compare.

I’m not a DB expert but normally database does case insensitive collation, so 
should we use do case insensitive compare here?
Thanks a lot.
