Excerpts from Renat Akhmerov's message of 2016-05-17 19:10:55 +0700: > Team, > > Our stable/mitaka branch is now broken by oslo.messaging 5.0.0. Global requirements for stable/mitaka has oslo.messaging>=4.0.0 so it can fetch 5.0.0. > > Just reminding that it breaks us because we intentionally modified RPCDispatcher like in [1]. It was needed for “at-least-once” delivery. In master we already agreed to remove that hack and work towards having a decent solution (there are options). The patch is [2]. But we need to handle it in mitaka somehow. > > Options I see: > Constrain oslo.messaging in global-requirements.txt for stable/mitaka with 4.6.1. Hard to do since it requires wide cross-project coordination. > Remove that hack in stable/mitaka as we did with master. It may be bad because this was wanted very much by some of the users > > Not sure what else we can do. You could set up your test jobs to use the upper-constraints.txt file in the requirements repo. What was the outcome of the discussion about adding the at-least-once semantics to oslo.messaging?
