Description Summer Long 2014-02-06 04:34:17 UTC

+++ This bug was initially created as a clone of Bug #929108 +++
Description of problem:

The cachemanagement API is hardcoded to use v1:

  https://github.com/openstack/glance/blob/master/glance/api/middleware/cache_manage.py#L36

whereas if the v2 API is enabled, but not v1, this is problematic as clients would want to use v2 across the board.

Steps to Reproduce:
1. Install Glance
2. Disable v1 in *-paste.ini files
3. Call any url related to the cache middleware.
  
Actual results:

$ curl -H "X-Auth-Token: $tok" http://10.130.50.34:9292/v1/cached_images | python -m json.tool
  % Total % Received % Xferd Average Speed Time Time Time Current

{
    "versions": [
        {
            "id": "v2.0",
            "links": [
                {
                    "href": "http://10.130.50.34:9292/v2/",
                    "rel": "self"
                }
            ],
            "status": "CURRENT"
        }
    ]
}


Expected results:

It should return the list of cached_images (if cache is enabled)

Comment 6 Andrew Dahms 2015-04-23 23:44:04 UTC

Moving back to 'NEW' until reassignment.

Comment 8 Andrew Dahms 2015-09-22 07:22:02 UTC

Re-assigning to Deepti for review.

Deepti - would you be able to look into this bug and determine whether it is still relevant for RHEL-OSP 7?

If not, perhaps we can close this bug.

Comment 9 Flavio Percoco 2015-09-29 06:25:03 UTC

This hasn't changed in Glance's API. The cache configuration is documented here[0] and, AFAICT, it won't change anytime soon.

This bugs depends on one that was closed as `UPSTREAM`. I'd advice to make sure the cache configuration process is documented and close this bug. If it's already documented, then I'd recommend closing this bug for now.

Comment 10 Deepti Navale 2015-09-30 00:51:34 UTC

Hi Flavio,

Appreciate the quick response. I'm adding the information to the Configuration Reference guide and will send out a link for a tech review in the next few days.

Thanks!
