Ah. fixing it in python neutron client would be just fine too. Its just the unfortunate usability issue that your on the cli, try and update the tenant's quota and it says "ok, done" and it didn't actually do the thing you thought it did. If your using the api or rest, the documentation should be ok to handle the tenant_id only thing.

I suppose we could just fail in that case. As quota-update is usually restricted to admin users this should not be a problem, unless the deployment uses per-service admin users. Let's see what happens with the nova spec Salvatore linked. That spec seems stuck to me. I think the reason is lack of reasons for raising its priority.

You'd just have to check if keystone was in use, and then do the extra resolve on update. I think the rest of the stuff can just remain using uuids? Once you accept that it's not a big deal to do a round trip to keystone, then we can do whatever we want. If there is value from a API usability perspective we'll just do that. If the issue is instead more the CLI UX, I would consider doing resolving the name (and possibly validating the tenant uuid) in python-neutronclient. Also, I've checked the docs [1] and [2] and neutron quota-update is not supposed to accept tenant name - so probably the claim made in the initial post on this thread did not apply to neutron after all.

Unfortunately the other issues are going to be the hard part to deal with. I probably shouldn't have brought up performance as a complaint at this stage. :) On Thu, Jul 30, 2015 at 3:26 AM, Fox, Kevin M <kevin....@pnnl.gov<mailto:kevin....@pnnl.gov>> wrote: Can a non admin update quotas?

This is something that has come up in Neutron discussions before. There are two issues here: 1. Performance: it will require a round-trip to Keystone on every request. 2. If the Neutron keystone user in unprivileged and the request context is unprivileged, we might not actually be allowed to tell if the tenant exists. The first we can deal with, but the second is going to be an issue that we might not be able to get around. How about as a temporary solution, we just confirm that the input is a UUID so names don't get used?

[nova,cinder,neutron] will allow you to do a quota-update using the tenant-name (instead of tenant-id). They will also allow you to do a quota-show tenant-name and get the expected values back. Then you go to the tenant and end up surprised that the quotas have not been applied and you can still do things you were not supposed to. It turns out that [nova,cinder,neutron] just created an entry on the quota table, inserting the tenant-name on the tenant-id field. "Surprise, surprise!" Ops lessons learned: use the tenant-id! Dev lessons learned: we need to validate better our inputs and refuse to update a tenant-id that does not exist. I have documented this behaviour on https://bugs.launchpad.net/neutron/+bug/1399065 and https://bugs.launchpad.net/neutron/+bug/1317515. I can reproduce it in IceHouse. Could someone please confirm if this is still the case on master? If not, which version of OpenStack addressed that?
