Sure, but that's not we're talking about here are we? The other tasks, like backporting changes for example, have been taken on by project teams. Even in your other email you mentioned that you've been doing backports and other tasks that you consider stable maint in a glance only context. That's something we changed in kilo which ttx referenced in [1] to enable that to happen, and it was the only way to scale things. The discussion here is about the cross project effort around stable branches, which by design is a more limited scope now. Right now the cross project effort around stable branch policy is really 2 things (both of which ttx already mentioned): 1. Keeping the gates working on the stable branches 2. Defining and enforcing stable branch policy. The only lever on #2 is that the global stable-maint-core is the only group which has add permissions to the per project stable core groups. (also the stable branch policy wiki, but that rarely changes) We specifically shrunk it to these 2 things in. [1] Well, really 3 things there, but since we're not doing integrated stable point releases in the future its now only 2. This is my whole argument that creating a new team doesn't do anything. Living under rel-mgt, some other project, or creating a new one isn't going to change the fact that cross-project stable maint is the same 2 tasks which basically nobody cares about, which TBH your email is just an indication of. Even if we wanted to grow to something beyond these 2 tasks they would still be the core of whatever it becomes and a lack of people caring about them will just block any potential scope growth. Frankly, this is the problem with any ML or open discussion about stable branch maint. Everyone has an opinion about everything but lacks actual context or never steps up to work on the cross-project side of this. I don't think creating a new team that has no repos or other artifacts and therefore no stackalytics credit (and by extension corporate chest thumping) is magically going to create people actually working on this. The logical follow on idea to the above is to create a stable branch policy doc repo and a project team to own that. But, I still don't think that solves the problem, especially since the real priority issue in this space is #1 which at most is a handful of us bothering to look at that, (well that and the stable policy barely ever changes) which honestly really isn't the majority of the stable-maint-core group. We also have a similar problem with gate issues on master and it's mostly the same people looking at these things there too. IMHO the only way for creating a separate project team to be useful is to re-centralize more responsibilities of stable maint, which is something I don't think we should do because we'll just hit the same scaling issues we had before kilo which prompted that change in the first place. It's the same problem every horizontal, cross project, or whatever you want to call it effort has with OpenStack's growth and why most have moved to the distributed self service models. But, if the goal is just to not make Doug responsible for #2, which is something ttx was primarily doing before, then I guess it's fine but we should be honest about it and just make ttx the new team leader. :) I honestly don't think anything else discussed will change by explicitly making it a separate team. -Matt Treinish > > > > > > > > > > [1] > > > > http://lists.openstack.org/pipermail/openstack-dev/2015-November/078 > > > > 281.html > > > >
