Flavio, I'm sorry if I'm being paranoid, I just think we should first focus on migrating all projects - those that will / should migrate - successfully and then pulling oslo.db out. Absolutely agree Pulling it out during Icehouse won't slow Oslo's db development down. So the only problem is that is too late for such big changes. Here I am absolutely agree. end of H-3 is not the best time =) So are you agree with next points? 1) In Havana focus on migrating in all projects to oslo.db code [Gary Kotton] It is worth going for. 2) in IceHouse create and move to oslo.db lib [Gary Kotton] I am in favor of this pending the stability of the oslo db code (which is on the right track) And are you agree that we should start working around olso.db lib now. [Gary Kotton] I am not sure what the effort for this is, but if this is just a matter of preparing it all for the start of Icehouse then cool, go for it. I nonetheless suggest speaking with Mark McLoughlinto try and learn lessons from the process with the common config module :) To be able to start switching to it at begin of IceHouse? And what about Glance patches ?;) Š•heir are ready since Aug 6, 2013 2:41 PM and there is no reviews at all. Best regards, Boris Pavlovic --- Mirantis Inc.

I'd also like to see other project migrated before pulling oslo.db out from oslo-incubator as I wrote before oslo.db code is used by: Nova, Neutron, Cinder, Ironic, Ceilometer use oslo.db. And we have already patches to switch in Glance to id. And we are woking in Keystone and Heat. Why (nova, neutron, cinder, ironic and ceilometer) is not enough to say that the code is OK? Because we're talking about the database code here. All projects depend / will depend on it. I wouldn't consider the whole API stable until all projects have successfully migrated to it. There are corner cases that could have been missed and that would require a new oslo.db release - assuming it has been pulled out - for them to be applied to projects using it. I'm sorry if I'm being paranoid, I just think we should first focus on migrating all projects - those that will / should migrate - successfully and then pulling oslo.db out. Hm, I really don't see big problems with migrating to oslo.db lib even in this moment, because in oslo-incubator and in oslo.db is the same code.. Could you explain what problem you see in process of migartion? (For me it is add one more requirments, remove openstack/db/.. folder, switch imports).. AFAIK, doing this will require to: 1) Set up a new repository 2) Make a release / tarball that you could use in the requirements file. 3) Change imports on all projects using oslo-incubator db code. All the steps above require people to review patches and step 3 needs to be done on 5 projects. In the meantime, you're also submitting patches to the not-yet migrated projects that are based on Oslo's code and those patches, if not yet merged - will also have to be updated. My concern is that there's a lot of work yet to be done on this area and I don't think it is ready to be pulled out yet. I'd prefer a migration process similar to oslo.config. All project were using it before it was pulled out and that was done when the API was considered stable. Pulling it out during Icehouse won't slow Oslo's db development down. Remaining projects can still be migrated and released during Havanna.
