delta/python-packages/sqlalchemy.git/test/ext, branch setinputsizes_oracle_string github.com: zzzeek/sqlalchemy.git Support AssociationProxy any() / has() / contains() to another AssociationProxy 2017-06-12T20:31:59+00:00 Mike Bayer mike_mp@zzzcomputing.com 2017-06-12T16:56:04+00:00 27a0bdcae0eb534dac9844e2ffa3d6bd3b1e8989 The :meth:`.AssociationProxy.any`, :meth:`.AssociationProxy.has` and :meth:`.AssociationProxy.contains` comparison methods now support linkage to an attribute that is itself also an :class:`.AssociationProxy`, recursively. After some initial attempts it's clear that the any() / has() of AssociationProxy needed to be reworked into a generic _criterion_exists() to allow this to work recursively without excess complexity. For the case of the multi-linked associationproxy, the usual checks of "any()" / "has()" correctness simply don't take place; for a single-link association proxy the error checking logic that takes place in relationship() has been ported to the local any() / has() methods.

and :meth:`.AssociationProxy.contains`
comparison methods now support linkage to an attribute that
is itself also an :class:`.AssociationProxy`, recursively.

After some initial attempts it's clear that the any() / has()
of AssociationProxy needed to be reworked into a generic
_criterion_exists() to allow this to work recursively without
excess complexity.  For the case of the multi-linked associationproxy,
the usual checks of "any()" / "has()" correctness simply don't
take place; for a single-link association proxy the error
checking logic that takes place in relationship() has been
ported to the local any() / has() methods.

Warn when declared_attr.cascading detected on mapped class 2017-06-06T21:16:58+00:00 Mike Bayer mike_mp@zzzcomputing.com 2017-06-06T21:13:54+00:00 4e1f5377d1c5443016cc6c5ae86b8053ead41647 A warning is emitted if the :attr:`.declared_attr.cascading` modifier is used with a declarative attribute that is itself declared on a class that is to be mapped, as opposed to a declarative mixin class or ``__abstract__`` class.

Implement in-place mutation operators for MutableSet, MutableList 2017-06-05T19:49:04+00:00 Mike Bayer mike_mp@zzzcomputing.com 2017-06-05T19:49:04+00:00 e8ad3988621a3caa69074fae8e9320bcabcf806d 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.

Don't hard-evaluate non-ORM @declared_attr for AbstractConcreteBase 2017-05-26T17:28:15+00:00 Mike Bayer mike_mp@zzzcomputing.com 2017-05-26T17:26:40+00:00 8b82369347641d1c9d64406462fa5527132c4880 Fixed bug where using :class:`.declared_attr` on an :class:`.AbstractConcreteBase` where a particular return value were some non-mapped symbol, including ``None``, would cause the attribute to hard-evaluate just once and store the value to the object dictionary, not allowing it to invoke for subclasses. This behavior is normal when :class:`.declared_attr` is on a mapped class, and does not occur on a mixin or abstract class. Since :class:`.AbstractConcreteBase` is both "abstract" and actually "mapped", a special exception case is made here so that the "abstract" behavior takes precedence for :class:`.declared_attr`.

Call proxied collection before invoking creator in associationlist.append() 2017-04-28T14:14:09+00:00 Mike Bayer mike_mp@zzzcomputing.com 2017-04-27T15:24:41+00:00 36275b0c2d8d3501bc0023e80d8433c0d54c0d9a Improved the association proxy list collection so that premature autoflush against a newly created association object can be prevented in the case where ``list.append()`` is being used, and a lazy load would be invoked when the association proxy accesses the endpoint collection.

Use baked lazyloading by default 2017-04-13T18:22:59+00:00 Mike Bayer mike_mp@zzzcomputing.com 2017-04-07T18:18:22+00:00 b7644319e85ce38c1a576802317a9058a6aed82d The ``lazy="select"`` loader strategy now makes used of the :class:`.BakedQuery` query caching system in all cases. This removes most overhead of generating a :class:`.Query` object and running it into a :func:`.select` and then string SQL statement from the process of lazy-loading related collections and objects. The "baked" lazy loader has also been improved such that it can now cache in most cases where query load options are used. Change-Id: Ic96792fffaa045ae9aa0a4657d6d29235d3efb85 Fixes: #3954

Track SchemaEventTarget types in as_mutable() 2017-03-30T21:52:10+00:00 Mike Bayer mike_mp@zzzcomputing.com 2017-03-30T21:52:10+00:00 07b63894cb8ff9529b406f196b5d7cb9af209e9e 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
