"auto" index names when using the "index=True"
flag on Column. The truncation only takes
place with the auto-generated name, not one
that is user-defined (an error would be
raised instead), and the truncation scheme
itself is now based on a fragment of an md5
hash of the identifier name, so that multiple
indexes on columns with similar names still
have unique names. [ticket:1855]
constraint gets moved to column level due to SQLite
AUTOINCREMENT keyword being rendered. [ticket:1812]
- remove some extra space in between constraint DDL
- added alias() to binary comparison test, fixing pg + mysql failures
- SchemaType and subclasses Boolean, Enum are now serializable,
including their ddl listener and other event callables.
[ticket:1694] [ticket:1698]
- AddConstraint/DropConstraint use the wrapper for _create_rule
- added test coverage for AddConstraint override of _create_rule
Uses a straight CheckConstraint with a generic expression. Preparing for boolean
constraint in [ticket:1589]
- CheckConstraint now accepts SQL expressions, though support for quoting of values
will be very limited. we don't want to get into formatting dates and such.
