https://bitbucket.org/zzzeek/sqlalchemy/commits/21f47124ab43/
Changeset:   21f47124ab43
Branch:      None
User:        zzzeek
Date:        2015-01-02 01:17:06+00:00
Summary:     - restate sort_tables in terms of a more fine grained
sort_tables_and_constraints function.
- The DDL generation system of :meth:`.MetaData.create_all`
and :meth:`.Metadata.drop_all` has been enhanced to in most
cases automatically handle the case of mutually dependent
foreign key constraints; the need for the
:paramref:`.ForeignKeyConstraint.use_alter` flag is greatly
reduced.  The system also works for constraints which aren't given
a name up front; only in the case of DROP is a name required for
at least one of the constraints involved in the cycle.
fixes #3282
