with 3.3.0 coming soon, one of the questions I heard is "what about 3.3.1" considering the number of patches fox bugs that went into master branch since since we branched to stabilize 3.3.0. i.e., most of the work in master branch has been focused on bug fixes)
so my suggestion is for 3.3.1 that we rebase from master, then move to backporting patches to that branch for the rest of 3.3 time frame.
while this poses a small risk, i believe its the best course forward to making ovirt 3.3 a more robust and stable version going forward.
this is mostly about ovirt-engine, and probably vdsm. for the other projects, its up to the maintainer, based on risk/benefit.
To make this happen for Vdsm, we need to slow things down a bit, stabilize what we have, and test it out.
Most of our work since ovirt-3.3 was bug fixing (23 patches), but some of the 101 patches we've got are related to refactoring (19), cleanups (27), test improvements (21), behind-the-scenes features (6), and visible features (5).
Refactoring included Zhou Zheng Sheng's Ubuntu-readiness patches, which may still incur surprises to sysV/systemd/upstart service framework, and changes to how network configurators are to be used.
Behind-the-scenes features include speedup to block-based storage: - One shot teardown. - Avoid Img and Vol produces in fileVolume.getV*Size - Make lvm.listPVNames() be based on vgs information. - One shot prepare. - Introduce lvm short filters.
Visible features are few, and only one of them: - clientIF: automatically unpause vms in EIO when SD becomes active carries some kind of a risk to a timely release. The rest of them are: - Support for multiple heads for Qxl display device - Add support for direct setting of cpu_shares when creating a VM - Introducing hidden_vlans configurable. - macspoof hooks: new hook script to enable macspoof filtering per vnic.
I think we can release vdsm-4.13.0 within a week if we put a hold on new features and big changes, and put enough effort into testing the mostly-changed areas: - service framework - VM lifecycle over block storage (including auto unpause) - network configuration
Then, we could release vdsm-4.13.z without risking the stability of ovirt-3.3.1.
Let's do it!
