There was indeed a missing route. I added the following routes:

Hi,
Is there a particular reason why an owner can't be specified when adding an
image? I.e., the following:
$ glance add name=testing owner=99 < testing
results in:
URI: http://jabba:9292/v1/images/22
Id: 22
Public: No
Name: testing
Status: active
Size: 36614
Disk format: None
Container format
Hi Juerg,
That's because 'owner' is not supported as an explicit parameter to 'glance
add'.
So as a result the CLI treats it a generic image property, and passes this to
the
API service via the header:
x-image-meta-property-owner: 2
The 'x-image-meta-property-' prefix is used to distinguis

Yup, makes sense. Thanks for the feedback. I agree that the external
caches are troublesome and we'll likely be focusing on the internal
ones. Whether that manifests itself as a memcache-like implementation or
another db view is unknown.
The other thing about in-process caching I like is the abili

Was reading up some more on cache invalidation schemes last night. The
best practice approach seems to be using a sequence ID in the key. When
you want to invalidate a large set of keys, just bump the sequence id.
This could easily be handled with a notifier that listens to instance
state changes.
I'd prefer to just set a different expectation for the user. Rather than
worrying about state change and invalidation, lets just set the expectation
that the system as a whole is eventually consistent. I would love to prevent

Alas, I let my patch get too stale to rebase properly. However, it is a
fairly "dumb" approach I took that can be demonstrated just from the

Here’s the way we’ve approached this:

is the only action that is always allowed).
- Once a VM has a task_state of “Deleting” (set in the API server) the
only action they can perform is delete
