[Openstack] swift object versions

I've recently started working on adding versioning to objects stored in swift (https://github.com/notmyname/swift/tree/version_manifest). Since this is such a requested feature, I thought it would be a good idea to get early input. I've created an etherpad (http://etherpad.openstack.org/swift-ob

Re: [Openstack] [RFC] Common config options module

Overall, I think it's a great thing to have commonality between the projects on option names and environment variables. I think it's worthwhile to push for that in the swift cli tool in the essex timeframe. On the topic of common config libraries, though, I think the differences are less import

Re: [Openstack] rpms for rhel5.x to install Open stack Object Storage

I suspect there is a communication gap somewhere, but this is certainly not the case. Openstack Object Storage (swift) is not deprecated. Glance provides a bridge between nova and swift, but all three are important, active projects. Sudhaker, I know that rpms exist for swift, but I don't know

Re: [Openstack] Keystone & Swift: swiftauth tenant namespace collisions?

I don't think that is exactly right, but my understanding of tenants vs accounts vs users may be lacking. Nonetheless, auth v2.0 support was added to the swift cli tool by Chmouel recently. Have you tried with the code in swift's trunk (also the 1.4.4 release scheduled for Tuesday)? --John On
