Fantastic write-up. I can't +1 enough the problem statement, which I think you've done a nice job of framing. We've taken steps to try to improve this, but none of them have been big enough. I feel we've reached a tipping point. I think many others do too, and several proposals being discussed all seem rooted in this same core issue. When it comes to the proposed solution, I'm +1 on that too, but part of that is that it's hard for me to ignore the limitations placed on us by our current review infrastructure (gerrit). If we ignored gerrit for a moment, is rapid increase in splitting out components the ideal workflow? Would we be better off finding a way to finally just implement a model more like the Linux kernel with sub-system maintainers and pull requests to a top-level tree? Maybe. I'm not convinced that split of repos is obviously better. You make some good arguments for why splitting has other benefits. Besides, even if we weren't going to split them and instead wanted to have separate branches, we'd have to take interface stability much more seriously. I think the work immediately needed overlaps quite a bit. In any case, let's not completely side-tracked on the end game workflow. I am completely on board with the idea that we have to move to a model that involves more than one team and spreading out the responsibility further than we have thus far. I don't think we can afford to wait much longer without drastic change, so let's make it happen. -- Russell Bryant _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
