There is a need to distinguish between server side py26 support which is
generally under the control of the service provider and py26 support on the
client side. For a service provider to push all of their hypervisors and
service machines to RHEL 7 is under their control but requiring all of their
users to do the same is much more difficult.

 

Thus, I feel there should be different decisions and communication w.r.t.
the time scales for deprecation of py26 on clients compared to the server
side. A project may choose to make them together but equally some may choose
to delay the mandatory client migration to py27 while requiring the server
to move.

Thanks Clark and Jeremy! This is very helpful. 

Serg, now knowing that CI testing is not going to continue in few weeks and
many other projects has dropped python 2.6 support or getting there, if
Murano decides the same that would be great. If Murano team decide to
continue the 2.6 support, we will need to enable support in tosca-parser as
well. As you mentioned it may not be a lot of work for us and we are totally
fine in making changes, but without automated tests it can be challenging in
future. 

Thanks!
