* | - Fixed rare TypeError which could occur when stringifying certainMike Bayer2015-09-231-1/+1

* | - The ``legacy_schema_aliasing`` flag, introduced in version 1.0.5Mike Bayer2015-09-191-67/+37
| | | | | | | | | | | | | | as part of :ticket:`3424` to allow disabling of the MSSQL dialect's attempts to create aliases for schema-qualified tables, now defaults to False; the old behavior is now disabled unless explicitly turned on. fixes #3434
* | - Added a new type-level modifier :meth:`.TypeEngine.evaluates_none`Mike Bayer2015-09-193-7/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | which indicates to the ORM that a positive set of None should be persisted as the value NULL, instead of omitting the column from the INSERT statement. This feature is used both as part of the implementation for :ticket:`3514` as well as a standalone feature available on any type. fixes #3250 - add new documentation section illustrating the "how to force null" use case of #3250 - alter our change from #3514 so that the class-level flag is now called "should_evaluate_none"; so that "evaluates_none" is now a generative method.

| | | | | | | | | | | | | | | | | | | | | | expression element which is late-evaluated at compile time. Previously, the function was only a conversion function which would handle different expression inputs by returning either a :class:`.Label` of a column-oriented expression or a copy of a given :class:`.BindParameter` object, which in particular prevented the operation from being logically maintained when an ORM-level expression transformation would convert a column to a bound parameter (e.g. for lazy loading). fixes #3531

The state of the object within each event is also defined. fixes #2677 - Added a new session lifecycle state :term:`deleted`. This new state represents an object that has been deleted from the :term:`persistent` state and will move to the :term:`detached` state once the transaction is committed. This resolves the long-standing issue that objects which were deleted existed in a gray area between persistent and detached. The :attr:`.InstanceState.persistent` accessor will **no longer** report on a deleted object as persistent; the :attr:`.InstanceState.deleted` accessor will instead be True for these objects, until they become detached. - The :paramref:`.Session.weak_identity_map` parameter is deprecated. See the new recipe at :ref:`session_referencing_behavior` for an event-based approach to maintaining strong identity map behavior. references #3517

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ``<function> WITHIN GROUP (ORDER BY <criteria>)``, using the method :class:`.FunctionElement.within_group`. A series of common set-aggregate functions with return types derived from the set have been added. This includes functions like :class:`.percentile_cont`, :class:`.dense_rank` and others. fixes #1370 - make sure we use func.name for all _literal_as_binds in functions.py so we get consistent naming behavior for parameters.
| * | - Added support for the SQL-standard function :class:`.array_agg`,Mike Bayer2015-08-261-0/+22
| | | | | | | | | | | | | | | | | | | | | which automatically returns an :class:`.Array` of the correct type and supports index / slice operations. As arrays are only supported on Postgresql at the moment, only actually works on Postgresql. fixes #3132

| | | | | | | | | | | | | | | | | | | | | | | | "super" instead of hardcoding to "self.type" for the default return value, the base Comparator was returning other_comparator.type. It's not clear what the rationale for this was, though in theory the base Comparator should possibly even throw an exception if the two types aren't the same (or of the same affinity?) . - mysql.SET was broken on this because the bitwise version adds "0" to the value to force an integer within column_expression, we are doing type_coerces here now in any case so that there is no type ambiguity for this operation

* | - merge of ticket_3514 None-handling branchMike Bayer2015-08-174-3/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Fixes to the ORM and to the postgresql JSON type regarding the ``None`` constant in conjunction with the Postgresql :class:`.JSON` type. When the :paramref:`.JSON.none_as_null` flag is left at its default value of ``False``, the ORM will now correctly insert the Json "'null'" string into the column whenever the value on the ORM object is set to the value ``None`` or when the value ``None`` is used with :meth:`.Session.bulk_insert_mappings`, **including** if the column has a default or server default on it. This makes use of a new type-level flag "evaluates_none" which is implemented by the JSON type based on the none_as_null flag. fixes #3514 - Added a new constant :attr:`.postgresql.JSON.NULL`, indicating that the JSON NULL value should be used for a value regardless of other settings. part of fixes #3514
* | - merge of ticket_3499 indexed access branchMike Bayer2015-08-1715-727/+873
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - The "hashable" flag on special datatypes such as :class:`.postgresql.ARRAY`, :class:`.postgresql.JSON` and :class:`.postgresql.HSTORE` is now set to False, which allows these types to be fetchable in ORM queries that include entities within the row. fixes #3499 - The Postgresql :class:`.postgresql.ARRAY` type now supports multidimensional indexed access, e.g. expressions such as ``somecol[5][6]`` without any need for explicit casts or type coercions, provided that the :paramref:`.postgresql.ARRAY.dimensions` parameter is set to the desired number of dimensions. fixes #3487 - The return type for the :class:`.postgresql.JSON` and :class:`.postgresql.JSONB` when using indexed access has been fixed to work like Postgresql itself, and returns an expression that itself is of type :class:`.postgresql.JSON` or :class:`.postgresql.JSONB`. Previously, the accessor would return :class:`.NullType` which disallowed subsequent JSON-like operators to be used. part of fixes #3503 - The :class:`.postgresql.JSON`, :class:`.postgresql.JSONB` and :class:`.postgresql.HSTORE` datatypes now allow full control over the return type from an indexed textual access operation, either ``column[someindex].astext`` for a JSON type or ``column[someindex]`` for an HSTORE type, via the :paramref:`.postgresql.JSON.astext_type` and :paramref:`.postgresql.HSTORE.text_type` parameters. also part of fixes #3503 - The :attr:`.postgresql.JSON.Comparator.astext` modifier no longer calls upon :meth:`.ColumnElement.cast` implicitly, as PG's JSON/JSONB types allow cross-casting between each other as well. Code that makes use of :meth:`.ColumnElement.cast` on JSON indexed access, e.g. ``col[someindex].cast(Integer)``, will need to be changed to call :attr:`.postgresql.JSON.Comparator.astext` explicitly. This is part of the refactor in references #3503 for consistency in operator use.

* | - add tests for InstanceEvents.init, InstanceEvents.init_failureMike Bayer2015-08-142-5/+68
| | | | | | | | | | | | | | - ensure that kwargs can be modified in-place within InstanceEvents.init and that these take effect for the __init__ method. - improve documentation for these and related events, including that kwargs can be modified in-place.
* | - The behavior of the :func:`.union` construct and related constructsMike Bayer2015-08-123-3/+150
| | | | | | | | | | | | | | | | | | such as :meth:`.Query.union` now handle the case where the embedded SELECT statements need to be parenthesized due to the fact that they include LIMIT, OFFSET and/or ORDER BY. These queries **do not work on SQLite**, and will fail on that backend as they did before, but should now work on all other backends. fixes #2528
