Hi,

We made great progress on porting Glance to Python 3. tox -e py34 now 
pass with a subset of tests and there is a non-voting py34 check job. I 
propose to make the py34 gate voting to avoid Python 3 regressions:

https://review.openstack.org/194048
"Make gate-glance-python34 voting"

When the py34 will become voting, it will no more possible to introduce 
code incompatible with Python 3, at least in the code tested by tox -e py34.



Currently, py34 uses the development branch of glance_store because 
there is no release including my Python 3 fixes. For glance_store, it 
would be nice if someone can review my last patches:

https://review.openstack.org/#/q/status:open+project:openstack/glance_store+branch:master+topic:py3,n,z

With these 3 patches to port drivers, it becomes to possible to run all 
tests in "tox -e py34", not only a subset of tests. So glance_store will 
be fully compatible with Python 3. My current patch "tox -e py34: use a 
subset of working tests" may be updated to run all tests, not only a 
subset, when other py3 patches will be merged.



Glance currently only uses PyMySQL on Python 3. For Python 2, there is a 
pending patch. It was blocked by oslo.db which didn't use PyMySQL. It 
changed: oslo.db now also uses PyMySQL driver by default for MySQL (but 
there is no release yet including this change). Glance patch:
