More discussions around the adoption of Pecan.<br>
<br>
I'd like to know what is the feeling of other folks about migrating<br>
existing APIs to Pecan as opposed to waiting for a new API version as<br>
an excuse to migrate the API implementation to Pecan?<br>
<br>
We discussed this in one of the sessions at the summit, I'd like to<br>
get a final consensus on what the desired migration path is for the<br>
overall community.<br>
<br>
IIRC, Cinder has a working version of the API with Pecan but there's<br>
not a real motivation to release a new version of it that will use<br>
the new implementation. Am I right?<br>
<br>
Nova, instead, will start migrating some parts but not all of them and<br>
it'll happen as part of the API v3. AFAIU.<br>
<br>
Recently a new patch was proposed in glance[0] and it contains a base<br>
implementation for the existing API v2. I love that patch and the fact<br>
that Oleh Anufriiev is working on it. What worries me, is that the<br>
patch re-implements an existing API and I don't think we should just<br>
swap them.<br></blockquote><div><br></div><div>Yes, I'm a bit worried about just swapping in a new implementation, too, much as I think the approach using Pecan is superior to the way we initially went. At this time I don't see a really compelling reason to switch. It would be neat however if there are any people who actually want to run the Pecan implementation of the v2 API--if so it might be worth taking it on into upstream. But unless we actually think there is some future development in v2.0 that will be substantially eased by using Pecan I think we should probably not switch implementations until there is a major version bump.</div>

<br>
Yes, we have tests (unit and functional) and that should be enough to<br>
make sure the new implementation works as the old one - Should it?<br>
Should it? - but...<br>
<br>
This most likely has to be evaluated in a per-project basis. But:<br>
<br>
- What are the thoughts of other folks on this matter?<br>
<br>
