Open Stack

Hey all,

We recently increased the version of eventlet we're using. The bump was 
driven by python3.5 enablement for oslo.messaging, which is a great 
thing to have exist. However, it has hard-broken designate - and not 
just the docs builds like happened for other projects.

There is a patch that has landed to upstream eventlet that will fix the 
designate issues, but it is not yet released.

I'd like to propose we revert the U-C bump and block 0.20 in our 
requirements. This hamstrings the 3.5 enablement a bit, but it unbreaks 
designate, and I'd argue that we need to prioritize not breaking 
services in cases like this. (also, because designate is broken, 
openstack-ansible has gate issues, and shade had gate issues until we 
removed designate from our gate config which was extremely sad making)

Sean McGinnis already proposed a patch to revert the bump:

which I think we should restore, then modify it to also include a 
requirements block. As soon as 0.21 is released, we can upgrade to that 
and get 3.5 for oslo.messaging back on track.

Thoughts?
