* Add "eager_parenthesis" late-compilation rule, use w/ PG JSON/HSTOREMike Bayer2016-10-011-0/+2
| | | | | | | | | | | | Added compiler-level flags used by Postgresql to place additional parenthesis than would normally be generated by precedence rules around operations involving JSON, HSTORE indexing operators as well as within their operands since it has been observed that Postgresql's precedence rules for at least the HSTORE indexing operator is not consistent between 9.4 and 9.5. Fixes: #3806 Change-Id: I5899677b330595264543b055abd54f3c76bfabf2
* Enable include_table for ON CONFLICT whereclausesMike Bayer2016-09-281-2/+1
| | | | | | | | | Fixed issue in new PG "on conflict" construct where columns including those of the "excluded" namespace would not be table-qualified in the WHERE clauses in the statement. Change-Id: Idfefc93e7e7b0d84805e23d5436d822d606f6a0a Fixes: #3807

* Repair PG BIGSERIAL w/ TypeDecorator, VariantMike Bayer2016-07-041-0/+3
| | | | | | | | | | | | | Some of the dialect impl memoization for TypeDecorator necessarily keeps the top-level TypeDecorator type around, since a user-defined type will have bind and result set processing behavior. For both TypeDecorator and Variant, PG dialect needs to ensure it's looking at the SQLAlchemy type to check for SmallInteger / BigInteger. Fixes: 3739 Change-Id: I2d45fb997f17c6272d6bb826a77d2dba665adae7 (cherry picked from commit 421fa6b8bf9f0c3c5041579c89ec405ce0f5e0b0)

* Support `postgresql_concurrently` on index dropping.Iuri de Silvio2016-06-081-5/+36
| | | | | | | | | | | | Also adds version detection so that DROP INDEX CONCURRENTLY only renders if the Postgresql version is 9.2 or higher; for CREATE INDEX CONCURRENTLY, version detection is added to allow the phrase to omit if the Postgresql version is less than 8.2.

| | | | | | | | | | | | | | | | | | | | | | | | | | persistence of JSON values in MySQL as well as basic operator support of "getitem" and "getpath", making use of the ``JSON_EXTRACT`` function in order to refer to individual paths in a JSON structure. fixes #3547 - Added a new type to core :class:`.types.JSON`. This is the base of the PostgreSQL :class:`.postgresql.JSON` type as well as that of the new :class:`.mysql.JSON` type, so that a PG/MySQL-agnostic JSON column may be used. The type features basic index and path searching support. fixes #3619 - reorganization of migration docs etc. to try to refer both to the fixes to JSON that helps Postgresql while at the same time indicating these are new features of the new base JSON type. - a rework of the Array/Indexable system some more, moving things that are specific to Array out of Indexable. - new operators for JSON indexing added to core so that these can be compiled by the PG and MySQL dialects individually - rename sqltypes.Array to sqltypes.ARRAY - as there is no generic Array implementation, this is an uppercase type for now, consistent with the new sqltypes.JSON type that is also not a generic implementation. There may need to be some convention change to handle the case of datatypes that aren't generic, rely upon DB-native implementations, but aren't necessarily all named the same thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

Any visit method that accepts keyword arguments (e.g. ``**kw``) will in most cases receive a keyword argument ``type_expression``, referring to the expression object that the type is contained within. For columns in DDL, the dialect's compiler class may need to alter its ``get_column_specification()`` method to support this as well. The ``UserDefinedType.get_col_spec()`` method will also receive ``type_expression`` if it provides ``**kw`` in its argument signature. fixes #3074
