Re: [openstack-dev] [Fuel] Dropping Python-2.6 support
I just made a general remark regarding why migrating to 2.7 is profitable (I understood Bartek's question this way). The point about Red Hat guaranteeing security fixes to 2.6 is a good one. Also, it's true we don't use SSL for fuelclient so yes, if other OpenStack projects keep 2.6 we should stick to it also. P.

Re: [openstack-dev] [Fuel] Dropping Python-2.6 support
Guys, The question not about Do we want to drop 2.6 or not?. The question about Do we have resources to do that in this release cycle?. It may be not as easy at it seems and it obviously requires additional testing. - Igor On Wed, Jan 14, 2015 at 11:18 AM, Przemyslaw Kaminski pkamin...@mirantis.com wrote: I just made a general remark regarding why migrating to 2.7 is profitable (I understood Bartek's question this way).

Re: [openstack-dev] [Fuel] Dropping Python-2.6 support
Hi, Roman, Indeed, we have to go forward and drop python 2.6 support. That's how it supposed to be, but, unfortunately, it may not be as easy as it seems at first glance. Fuel Master is flying on top of Cent OS 6.5 which doesn't have python 2.7 at all. So we must either run master node on Cent OS 7 or build python2.7 for Cent OS 6.5. The first case, obviously, requires a lot of work, while the second one is not.

Re: [openstack-dev] [Fuel] Dropping Python-2.6 support
Hi Dmitry, Client uses REST API to interact with Fuel, how is Python version a factor? Fuel client is written in python it means it won't work on the master node with 2.6 python if you drop compatibility with it. What exactly is the use cases that requires a new client deployed on an old Fuel master node (or vice versa)? Fuel master node upgrade, we install newer client during the upgrade. It's not that hard ... It looks not so hard, but it should be well tested before it's merged, and it's risky because fuel client is installed on the host system, not into the container, hence in case if something goes wrong we cannot make automatic rollback.

Re: [openstack-dev] [Fuel] Dropping Python-2.6 support
The python27 packages Ihar has linked do not conflict with the system python 2.6, so I don't see any problems with the rollback here. Is rollback the only concern for the master node upgrade use case?

Fuel client is written in python it means it won't work on the master node with 2.6 python if you drop compatibility with it. What exactly is the use cases that requires a new client deployed on an old Fuel master node (or vice versa)? Fuel master node upgrade, we install newer client during the upgrade. It's not that hard ... It looks not so hard, but it should be well tested before it's merged, and it's risky because fuel client is installed on the host system, not into the container, hence in case if something goes wrong we cannot make automatic rollback.

Client uses REST API to interact with Fuel, how is Python version a factor? What exactly is the use cases that requires a new client deployed on an old Fuel master node (or vice versa)? Or we can try to install python 2.7 on the master during the upgrade. Lets do this. It's not that hard, see the link in an email from Ihar Hrachyshka on this thread. As for Nailgun I don't see any problems to use 2.7.
