* Add keywords to MutableList.sort()Mike Bayer2020-01-231-0/+24
| | | | | | | | Added keyword arguments to the :meth:`.MutableList.sort` function so that a key function as well as the "reverse" keyword argument can be provided. Fixes: #5114 Change-Id: Iefb29e1ccadfad6ecba558ce575029307001b88e
* Add __reduce_ex__ to MutableList; add compat for older picklesMike Bayer2019-04-091-0/+94
| | | | | | | | | | | | | | | | | | Fixed bug where using ``copy.copy()`` or ``copy.deepcopy()`` on :class:`.MutableList` would cause the items within the list to be duplicated, due to an inconsistency in how Python pickle and copy both make use of ``__getstate__()`` and ``__setstate__()`` regarding lists. In order to resolve, a ``__reduce_ex__`` method had to be added to :class:`.MutableList`. In order to maintain backwards compatibility with existing pickles based on ``__getstate__()``, the ``__setstate__()`` method remains as well; the test suite asserts that pickles made against the old version of the class can still be deserialized by the pickle module. Also modified sqlalchemy.testing.util.picklers to return picklers all the way through pickle.HIGHEST_PROTOCOL. Fixes: #4603 Change-Id: I7f78b9cfb89d59a706248536c553dc5e1d987b88
* Implement relationship to AliasedClass; deprecate non primary mappersMike Bayer2019-01-251-18/+0
| | | | | | | | | | | | | | | | | | | | | | | | Implemented a new feature whereby the :class:`.AliasedClass` construct can now be used as the target of a :func:`.relationship`. This allows the concept of "non primary mappers" to no longer be necessary, as the :class:`.AliasedClass` is much easier to configure and automatically inherits all the relationships of the mapped class, as well as preserves the ability for loader options to work normally. - introduce new name for mapped_table, "persist_selectable". this is the selectable that selects against the local mapper and its superclasses, but does not include columns local only to subclasses. - relationship gains "entity" which is the mapper or aliasedinsp. - clarfiy name "entity" vs. "query_entity" in loader strategies. Fixes: #4423 Fixes: #4422 Fixes: #4421 Fixes: #3348 Change-Id: Ic3609b43dc4ed115006da9ad9189e574dc0c72d9
* Post black reformattingMike Bayer2019-01-061-10/+23
| | | | | | | | | | | | | Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues. Change-Id: I4f72d3ba1380dd601610ff80b8fb06a2aff8b0fe
* Run black -l 79 against all source filesMike Bayer2019-01-061-204/+251
| | | | | | | | | | | | | | This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues. Change-Id: I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9
* Ignore non-primary mappers within mutable instrumentationMike Bayer2018-03-121-0/+22
| | | | | | | | | | | | 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. Change-Id: I2630d9f771a171aece03181ccf9159885f68f25e Fixes: #4215
* Propagate attachment events for ARRAYMike Bayer2017-12-041-0/+20
| | | | | | | | | | | | 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`. Change-Id: If8c57615860883837f6cf72661e46180a77778c1 Fixes: #4141
* Implement in-place mutation operators for MutableSet, MutableListMike Bayer2017-06-051-0/+60
| | | | | | | | | | | 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. Change-Id: Ib357a96d3b06c5deb6b53eb304a8b9f1dc9e9ede Fixes: #3853
* Add AttributeEvents.modifiedMike Bayer2017-05-231-0/+16
| | | | | | | | | | 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. Change-Id: Ic152f1d5c53087d780b24ed7f1f1571527b9e8fc Fixes: #3303
* Ensure we check that SQL expression has an .info attributeMike Bayer2017-04-041-2/+4
| | | | | | | | | | 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()Mike Bayer2017-03-301-0/+43
| | | | | | | | | | | | | | 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. Change-Id: Ib04df862c58263185dbae686c548fea3e12c46f1 Fixes: #3950

* - Fixed regression in the :mod:`sqlalchemy.ext.mutable` extensionMike Bayer2015-05-211-9/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | as a result of the bugfix for :ticket:`3167`, where attribute and validation events are no longer called within the flush process. The mutable extension was relying upon this behavior in the case where a column level Python-side default were responsible for generating the new value on INSERT or UPDATE, or when a value were fetched from the RETURNING clause for "eager defaults" mode. The new value would not be subject to any event when populated and the mutable extension could not establish proper coercion or history listening. A new event :meth:`.InstanceEvents.refresh_flush` is added which the mutable extension now makes use of for this use case. fixes #3427 - Added new event :meth:`.InstanceEvents.refresh_flush`, invoked when an INSERT or UPDATE level default value fetched via RETURNING or Python-side default is invoked within the flush process. This is to provide a hook that is no longer present as a result of :ticket:`3167`, where attribute and validation events are no longer called within the flush process. - Added a new semi-public method to :class:`.MutableBase` :meth:`.MutableBase._get_listen_keys`. Overriding this method is needed in the case where a :class:`.MutableBase` subclass needs events to propagate for attribute keys other than the key to which the mutable type is associated with, when intercepting the :meth:`.InstanceEvents.refresh` or :meth:`.InstanceEvents.refresh_flush` events. The current example of this is composites using :class:`.MutableComposite`.

* - [bug] the value of a composite attribute is nowMike Bayer2011-10-261-7/+36
| | | | | | | | | | | | | | | | | expired after an insert or update operation, instead of regenerated in place. This ensures that a column value which is expired within a flush will be loaded first, before the composite is regenerated using that value. [ticket:2309] - [bug] The fix in [ticket:2309] also emits the "refresh" event when the composite value is loaded on access, even if all column values were already present, as is appropriate. This fixes the "mutable" extension which relies upon the "load" event to ensure the _parents dictionary is up to date, fixes [ticket:2308]. Thanks to Scott Torborg for the test case here.
