- Fixed issue where inadvertent use of the Python ``contains``

2016-02-02T15:41:01+00:00

override with a column expression (e.g. by using ``'x' in col``)
would cause an endless loop in the case of an ARRAY type, as Python
defers this to ``__getitem__`` access which never raises for this
type.  Overall, all use of ``__contains__`` now raises
NotImplementedError.
fixes #3642

get PG stuff working

- start trying to move things into slots. This seems to reduce the

2015-01-04T06:53:42+00:00

size of the many per-column objects we're hitting, but somehow the overall memory is
hardly being reduced at all in initial testing

- The :meth:`.Operators.match` operator is now handled such that the

2014-12-04T23:29:56+00:00

return type is not strictly assumed to be boolean; it now
returns a :class:`.Boolean` subclass called :class:`.MatchType`.
The type will still produce boolean behavior when used in Python
expressions, however the dialect can override its behavior at
result time.  In the case of MySQL, while the MATCH operator
is typically used in a boolean context within an expression,
if one actually queries for the value of a match expression, a
floating point value is returned; this value is not compatible
with SQLAlchemy's C-based boolean processor, so MySQL's result-set
behavior now follows that of the :class:`.Float` type.
A new operator object ``notmatch_op`` is also added to better allow
dialects to define the negation of a match operation.

- add postgresql_regconfig argument to PG dialect for match() operator,

2014-07-08T22:18:04+00:00

implements PG's to_tsquery('regconfig', 'arg') pattern. fixes #3078

- Fixed bug where the :meth:`.Operators.and`,

2014-05-24T18:35:28+00:00

:meth:`.Operators.__or__` and :meth:`.Operators.__invert__`
operator overload methods could not be overridden within a custom
:class:`.TypeEngine.Comparator` implementation.
