Ignore non-primary mappers within mutable instrumentation

2018-03-12T16:51:54+00:00

Fixed bug where using :meth:`.Mutable.associate_with` or
:meth:`.Mutable.as_mutable` in conjunction with a class that has non-
primary mappers set up with alternatively-named attributes would produce an
attribute error.  Since non-primary mappers are not used for persistence,
the mutable extension now excludes non-primary mappers from its
instrumentation steps.

Fixes: #4215

Propagate attachment events for ARRAY

2017-12-04T21:49:02+00:00

Fixed regression in :class:`.ARRAY` datatype caused by
:ticket:`3964`, which is essentially the same
issue as that of :ticket:`3832`, where column attachment events
for :class:`.ARRAY` would not be invoked.   This breaks the use case
of using declarative mixins that declare a :class:`.Column` which
makes use of :meth:`.MutableList.as_mutable`.

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`.

Change-Id: I38254834d3d79c9b339289a8163eb4789ec4c931
Fixes: #3956

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.
