Implement in-place mutation operators for MutableSet, MutableList

2017-06-05T19:49:04+00:00

Implemented in-place mutation operators ``__ior__``, ``__iand__``,
``__ixor__`` and ``__isub__`` for :class:`.mutable.MutableSet`
and ``__iadd__`` for :class:`.mutable.MutableList` so that change
events are fired off when these mutator methods are used to alter the
collection.

Fixes: #3853

Add AttributeEvents.modified

2017-05-23T19:14:04+00:00

Added new event handler :meth:`.AttributeEvents.modified` which is
triggered when the func:`.attributes.flag_modified` function is
invoked, which is common when using the :mod:`sqlalchemy.ext.mutable`
extension module.

Ensure we check that SQL expression has an .info attribute

2017-04-04T13:06:13+00:00

Fixed regression released in 1.1.8 due to :ticket:`3950` where the
deeper search for information about column types in the case of a
"schema type" or a :class:`.TypeDecorator` would produce an attribute
error if the mapping also contained a :obj:`.column_property`.

Track SchemaEventTarget types in as_mutable()

2017-03-30T21:52:10+00:00

Fixed bug in :mod:`sqlalchemy.ext.mutable` where the
:meth:`.Mutable.as_mutable` method would not track a type that had
been copied using :meth:`.TypeEngine.copy`.  This became more of
a regression in 1.1 compared to 1.0 because the :class:`.TypeDecorator`
class is now a subclass of :class:`.SchemaEventTarget`, which among
other things indicates to the parent :class:`.Column` that the type
should be copied when the :class:`.Column` is.  These copies are
common when using declarative with mixins or abstract classes.

Corrects some warnings and adds tox config.  Adds DeprecationWarning
to the error category.   Large sweep for string literals w/ backslashes
as this is common in docstrings
