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:


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? :)
