After having some conversations with folks at the Ops Midcycle a
few weeks ago, and observing some of the more recent email threads
related to glance, glance-store, the client, and the API, I spent
last week contacting a few of you individually to learn more about
some of the issues confronting the Glance team. I had some very
frank, but I think constructive, conversations with all of you about
the issues as you see them. As promised, this is the public email
thread to discuss what I found, and to see if we can agree on what
the Glance team should be focusing on going into the Mitaka summit
and development cycle and how the rest of the community can support
you in those efforts.

Doug, thanks for reaching out here.

I've been looking into the existing task-based-upload that Doug mentions:
can anyone clarify the following?

On a default devstack install you can do this 'task' call:

http://paste.openstack.org/show/462919

as an alternative to the traditional image upload (the bytes are streamed
from the URL).

It's not clear to me if this is just an interesting example of the kind
of operator specific thing you can configure tasks to do, or a real
attempt to define an alternative way to upload images.

It's the old copy-from moved to a task to allow for other tasks to be
executed before the image data is stored. This effort was called "new
upload workflow"[0], which intended to allow for the above but also to
avoid blocking webheads on image download.

That said, and as mentioned in other replies on this thread, I think
this is an API that would be useful for OPs not just for importing
images but also execute other "tasks". As far as the public API goes,
I don't think we should recommend it nor make it public. At least not
in its current state.
