* - A deep improvement to the recently added :meth:`.TextClause.columns`Mike Bayer2016-01-146-154/+355
| | | | | | | | | | | | | | | | | | | method, and its interaction with result-row processing, now allows the columns passed to the method to be positionally matched with the result columns in the statement, rather than matching on name alone. The advantage to this includes that when linking a textual SQL statement to an ORM or Core table model, no system of labeling or de-duping of common column names needs to occur, which also means there's no need to worry about how label names match to ORM columns and so-forth. In addition, the :class:`.ResultProxy` has been further enhanced to map column and string keys to a row with greater precision in some cases. fixes #3501 - reorganize the initialization of ResultMetaData for readability and complexity; use the name "cursor_description", define the task of "merging" cursor_description with compiled column information as its own function, and also define "name extraction" as a separate task. - fully change the name we use in the "ambiguous column" error to be the actual name that was ambiguous, modify the C ext also

* - Multi-tenancy schema translation for :class:`.Table` objects is added.Mike Bayer2016-01-089-44/+157
| | | | | | | | | This supports the use case of an application that uses the same set of :class:`.Table` objects in many schemas, such as schema-per-user. A new execution option :paramref:`.Connection.execution_options.schema_translate_map` is added. fixes #2685 - latest tox doesn't like the {posargs} in the profile rerunner

Custom plugins can be written which will be given the chance up front to alter and/or consume the engine's URL and keyword arguments, and then at engine create time will be given the engine itself to allow additional modifications or event registration. Plugins are written as a subclass of :class:`.CreateEnginePlugin`; see that class for details. fixes #3536

* | - Added :class:`.mysql.JSON` for MySQL 5.7. The JSON type providesMike Bayer2016-01-0619-273/+788
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | no longer called for an UPDATE or DELETE statement emitted via plain text or via the :func:`.text` construct, affecting those drivers that erase cursor.rowcount once the cursor is closed such as SQL Server ODBC and Firebird drivers. fixes #3622
