[openstack-dev] [neutron] alembic 0.7.1 will break neutron's "heal" feature which assumes a fixed set of potential autogenerate types

hey neutron -

Just an FYI, I’ve added https://review.openstack.org/#/c/137989/ / https://launchpad.net/bugs/1397796 to refer to an issue in neutron’s “heal” script that is going to start failing when I put out Alembic 0.7.1, which is potentially later today / this week.

The issue is pretty straightforward,  Alembic 0.7.1 is adding foreign key autogenerate (and really, could add more types of autogenerate at any time), and as these new commands are revealed within the execute_alembic_command(), they are not accounted for, so it fails.   I’d recommend folks try to push this one through or otherwise decide how this issue (which should be expected to occur many more times) should be handled.

Just a heads up in case you start seeing builds failing!
