Hello Everyone,

Below is the progress on "Drop Python 2.7 Support" at end of R-13 week.

Schedule: https://governance.openstack.org/tc/goals/selected/ussuri/drop-py27.html#schedule

* Deadline was M-2 (R-13 week).

* Things are breaking and being fixed daily. 

* Do not worry about the gate failure, it is better to break it now and fix so that we can smoothly release Ussuri.

* Tempest has dropped the py2 and stop running the py2 jobs and so does devstack. 

* tempest-full job has been moved to py2 (it started running on py3 when devstack default to py3). This job is not supposed
to run on master gate (except d-g which should keep running on py2 jobs). tempest-full-py3 is the py3 version of it. But few
master jobs derived from tempest-full needs to either start using tempest-full-py3 or explicitly enable py3. I will be working 
on those next week.

* Bugs & Status:  No open bugs as of now. Below is the status of last week's bugs.

** QA dropped py3.5 support also from many tooling like stackviz etc which are branchless and should keep working on
stable py3.5 env. We have reverted the dropping py3.5 and working now.

** Nova stable branches are still falling for the u-c reason on nova-live-migration. Fixes are up[2]
*** Fixed and gate is green.

* * Tempest tox 'all-plugin' usage issue[3]
*** Fixed and gate is green.

** neutron-vpass in-tree plugin issue
*** Fixed and gate is green.

NOTE: I know few py2.7 drop patches are failing on few projects, I will continue debugging those. Help from the failing project will be greatly appreciated to meet the deadline.

Project wise status and need reviews:
Phase-1 status:
The OpenStack services have not merged the py2 drop patches:
NOTE: This was supposed to be completed by milestone-1 (Dec 13th, 19).

Phase-2 status:
By today, we should be completing the phase-2 work which is nothing but drop py2 from everything except requirement repo.
But we have few repos to merge the patches on priority. 

* Open review: https://review.opendev.org/#/q/topic:drop-py27-support+status:open

How you can help:
- Review the patches. Push the patches if I missed any repo.
