As part of upgrading py-alembic to latest upstream version this version of py-alembic is forked as the latest version uses sqlalchemy from 1.3.X branches. Once the dependent ports are fixed py-alembic will be updated to the latest.

Alembic is a new database migrations tool, written by the author of
|
|
SQLAlchemy. A migrations tool offers the following functionality:
|
|
|
|
- Can emit ALTER statements to a database in order to change the structure of
|
|
tables and other constructs
|
|
- Provides a system whereby "migration scripts" may be constructed; each
|
|
script indicates a particular series of steps that can "upgrade" a target
|
|
database to a new version, and optionally a series of steps that can
|
|
"downgrade" similarly, doing the same steps in reverse.
|
|
- Allows the scripts to execute in some sequential manner.
|
|
|
|
This is 1.4.X branch that works with sqlalchemy 1.2.X branch.
