        The behavior here is as follows:

        * If the attribute is a column-mapped property, i.e.
          :class:`.ColumnProperty`, which is mapped directly
          to a schema-level :class:`.Column` object, this attribute
          will return the :attr:`.SchemaItem.info` dictionary associated
          with the core-level :class:`.Column` object.

        * If the attribute is a :class:`.ColumnProperty` but is mapped to
          any other kind of SQL expression other than a :class:`.Column`,
          the attribute will refer to the :attr:`.MapperProperty.info`
          dictionary associated directly with the :class:`.ColumnProperty`,
          assuming the SQL expression itself does not have its own ``.info``
          attribute (which should be the case, unless a user-defined SQL
          construct has defined one).

        * If the attribute refers to any other kind of
          :class:`.MapperProperty`, including :class:`.RelationshipProperty`,
          the attribute will refer to the :attr:`.MapperProperty.info`
          dictionary associated with that :class:`.MapperProperty`.

        * To access the :attr:`.MapperProperty.info` dictionary of the
          :class:`.MapperProperty` unconditionally, including for a
          :class:`.ColumnProperty` that's associated directly with a
          :class:`.schema.Column`, the attribute can be referred to using
          :attr:`.QueryableAttribute.property` attribute, as

��ZRS(s�A 3-tuple of added, unchanged and deleted values,
    representing the changes which have occurred on an instrumented
    attribute.

    The easiest way to get a :class:`.History` object for a particular
    attribute on an object is to use the :func:`.inspect` function::

        from sqlalchemy import inspect

        hist = inspect(myobject).attrs.myattribute.history

    Each tuple member is an iterable sequence:

    * ``added`` - the collection of items added to the attribute (the first
      tuple element).

    * ``unchanged`` - the collection of items that have not changed on the
      attribute (the second tuple element).

    * ``deleted`` - the collection of items that have been removed from the
      attribute (the third tuple element).

Return a :class:`.History` record for the given object

    This is the **pre-flush** history for a given attribute, which is
    reset each time the :class:`.Session` flushes changes to the
    current database transaction.

    .. note::

        Prefer to use the :attr:`.AttributeState.history` and
        :meth:`.AttributeState.load_history` accessors to retrieve the
        :class:`.History` for instance attributes.


    :param obj: an object whose class is instrumented by the
      attributes package.

    :param key: string attribute name.

    :param passive: indicates loading behavior for the attribute
       if the value is not already present.   This is a
       bitflag attribute, which defaults to the symbol
       :attr:`.PASSIVE_OFF` indicating all necessary SQL
       should be emitted.

    .. seealso::

        :attr:`.AttributeState.history`

        :meth:`.AttributeState.load_history` - retrieve history
        using loader callables if the value is not locally present.

    sNPassing True for 'passive' is deprecated. Use attributes.PASSIVE_NO_INITIALIZEsFPassing False for 'passive' is deprecated.

    This is the same underlying method used when a lazy loader
    fires off and loads additional data from the database.
    In particular, this method can be used by application code

    separate queries, which can then be attached to an instance

    the flush process for an object that has no changes, even if marked dirty
    via this method.  However, a :meth:`.SessionEvents.before_flush` handler
    will be able to see the object in the :attr:`.Session.dirty` collection and
    may establish changes on it, which will then be included in the SQL
