This repo is now testing only with Python 3, so let's make a few cleanups: - Remove obsolete sections from setup.cfg - Update requirements, no need for python_version anymore - Switch to using sphinx-build, fix problems found - Use newer openstackdocstheme and Sphinx versions - Cleanup */source/conf.py to remove now obsolete content. - Remove install_command from tox.ini, the default is fine Change-Id: I6c593dff382a7aac4d758f802173f5a9f1e66182

Remove SQL Schema Downgrades
Trove still has the downgrade method on its migration files. Following the cross-project spec https://review.openstack.org/#/c/152337/ we are supposed to remove the downgrade to avoid data inconsistency, lack of integrity, etc. This approach was already done in many projects like Keystone, Magnum, Nova and others [2][3][4][5].
Launchpad Blueprint: https://blueprints.launchpad.net/trove/+spec/remove-sql-schema-downgrades
Problem Description
Downgrades are not the best idea when thinking about data integrity. A cross project spec was proposed to start removing downgrades and it was already done in many projects. We need to delete downgrade from migration files.
Proposed Change
Remove downgrades from migration files and remove the command from trove-manage.
