OpenStack Glance upgrade script breaks with SQLAlchemy 1.1.11 but not 1.0.12

[Byron Yi]

It appears that autoincrement=True is set by default for primary key when upgrading from 1.0 to 1.1, no matter if it is integer (which is not in glance; they use VARCHAR(36)).

See https://bugs.launchpad.net/glance/+bug/1723097

It defaults to True in 1.0, the change in 1.1 is that it defaults to "auto":

http://docs.sqlalchemy.org/en/rel_1_1/changelog/migration_11.html#no-more-generation-of-an-implicit-key-for-composite-primary-key-w-auto-increment

if that migrate operation is altering a column from Integer to String,
then it's likely this is confusing things. So this is a
sqlalchemy-migrate bug.

Your migrate is out of date. this was fixed one year ago:

Thanks Mike. Glad to know it’s been fixed.
