ML thread will probably work for some initial exploration, but with James leading the Zuul v3 design and implementation he's in the best position to say whether it's going to be sane to support having changes in multiple repos which must test and merge together rather than being able to merge one before the other. Previously we've seen the idea of atomic merges coordinated across multiple repositories to be a sign of poor software design, and as such have actively discouraged the notion (it did come up briefly during the original cross-repo dependencies design, and was pretty quickly rejected as unsanitary). Anyway, I'll give him a heads up on this since he likely doesn't follow Horizon-specific discussions very closely. -- Jeremy Stanley __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
