[dev] 'sqlalchemy.exc.NoSuchTableError: migration_tmp' errors due to SQLite 3.26.0

Just to note that I'm currently unable to run nova unit tests locally on Fedora 29 without downgrading my sqlite package. The error I'm seeing is: sqlalchemy.exc.NoSuchTableError: migration_tmp The root cause appears to be a change in 3.26.0 which is breaking sqlalchemy-migrate, as noted here: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1807262 Corey Bryant has proposed the patch for this patch, linked below, which should resolve this. Any chance an sqlalchemy-migrate core could look at this before I reach the point of not being able to downgrade my sqlite package and run nova unit tests? :) https://review.openstack.org/#/c/623564/5 Stephen
