[Starlingx-discuss] Python 2to3 code porting

[Rowsell, Brent]

The priority of this needs to be discussed at the next architecture meeting.
With all  current churn and lack of a working build, this activity in my opinion needs to wait.

Subject: [Starlingx-discuss] Python 2to3 code porting

Hi, there,
I just wonder if anyone is already working on this task now?
I created a story days ago, and studied most of our Python code and the python rpms in the system.
Here's the conclusions:

1.       Most of the Tis dependency python packages are already Python 2/3 compatible, but still some exceptions:

a.       The following packages are Python2 only and same for the latest code tree:

                                                               i.      createrepo-0.9.9 (used by cgcs-patch-controller)

                                                             ii.      net-snmp-5.7.2 (used by snmp-audittrail)

                                                            iii.      pyparted-3.9 (used by sysinv)

b.      The following packages are Python 2 but the latest version has Python 3 support, need upgrade:

                                                               i.      python-daemon-1.6 (used by logmgmt)
             * This analysis is still on-going, more packages may be found.

2.       The Python modules for Python 2/3 compatibility (python-futures and python-six) are already included.

3.       Some of the openstack packages/dependencies are Python 2 only, we may need to find a good version of Openstack to upgrade.

We can start to clean our code first, I think we follow the guideline here, one topic each time, how do you think?
