* sqlite: reflect primary key constraint names, fixes #3629Diana Clarke2016-01-271-1/+10

* - unfortunately we need to match within join where col.key does not matchMike Bayer2016-01-261-2/+1
| | | | | what's given so we need to use a set() here. contains_column is not within any performance paths
* - rework ColumnCollection to no longer persist "all_col_set"; we don'tMike Bayer2016-01-261-20/+9
| | | | | | | | | | | | | need this collection except in the extend/update uses where we create it ad-hoc. simplifies pickling. Compatibility with 1.0 should be OK as ColumnColleciton uses __getstate__ in any case and the __setstate__ contract hasn't changed. - Fixed bug in :class:`.Table` metadata construct which appeared around the 0.9 series where adding columns to a :class:`.Table` that was unpickled would fail to correctly establish the :class:`.Column` within the 'c' collection, leading to issues in areas such as ORM configuration. This could impact use cases such as ``extend_existing`` and others. fixes #3632
* - The workaround for right-nested joins on SQLite, where they are rewrittenMike Bayer2016-01-262-7/+14
| | | | | | | | | | as subqueries in order to work around SQLite's lack of support for this syntax, is lifted when SQLite version 3.7.16 or greater is detected. fixes #3634 - The workaround for SQLite's unexpected delivery of column names as ``tablename.columnname`` for some kinds of queries is now disabled when SQLite version 3.10.0 or greater is detected. fixes #3633
* - add a new qualifier "native" vs. "dbapi" unicode to avoidMike Bayer2016-01-241-0/+5
| | | | | | profiling problems here - add extras_require to setup.py for the most common DBAPIs - rework tox.ini to use extras, specify a test matrix built in

| | | | per server
* - documenation updates to clarify specific SQLite versionsMike Bayer2016-01-211-2/+14
| | | | | | | | | that have problems with right-nested joins and UNION column keys; references #3633 references #3634. backport from 1.1 to 0.9 announcing 1.1 as where these behaviors will be retired based on version-specific checks - fix test_resultset so that it passes when SQLite 3.10.0 is present, references #3633
* - Added new parameter :paramref:`.orm.mapper.passive_deletes` toMike Bayer2016-01-202-1/+44
| | | | | | | | available mapper options. This allows a DELETE to proceed for a joined-table inheritance mapping against the base table only, while allowing for ON DELETE CASCADE to handle deleting the row from the subclass tables. fixes #2349
* - The unsupported Sybase dialect now raises ``NotImplementedError``Mike Bayer2016-01-201-5/+1
| | | | | when attempting to compile a query that includes "offset"; Sybase has no straightforward "offset" feature. fixes #2278
* - generalize the verbiage on LargeBinary so that it doesn'tMike Bayer2016-01-201-10/+5

* - update oracle JDBC driver URL, fixes #3554Mike Bayer2016-01-201-2/+1

* - cross link for concrete helper classesMike Bayer2016-01-201-0/+16
| | | | | - remove redundant concrete helper docs from declarative docs, two places is enough
* - add a note that the literal_binds flag should be usedMike Bayer2016-01-201-1/+11
| | | | when cross-compiling from DDL to SQL, fixes #3615
* Fix ArrayOfEnum's handling of empty arrays.pr/229Chase2016-01-191-1/+1
| | | Prior to this change a value of `'{}'` would split into the list `['']`.
* - the order in which _generate_backref() for different mappers is calledMike Bayer2016-01-191-1/+1
| | | | | is random; therefore it may be called against the subclass mapper first, so need to check .concrete on both sides, references #3630
* - calling str() on a core sql construct has been made more "friendly",Mike Bayer2016-01-196-2/+56
| | | | | | | | | | when the construct contains non-standard sql elements such as returning, array index operations, or dialect-specific or custom datatypes. a string is now returned in these cases rendering an approximation of the construct (typically the postgresql-style version of it) rather than raising an error. fixes #3631 - add within_group to top-level imports - add eq_ignore_whitespace to sqlalchemy.testing imports
* - Fixed issue where two same-named relationships that refer toMike Bayer2016-01-192-10/+16
| | | | | | | | a base class and a concrete-inherited subclass would raise an error if those relationships were set up using "backref", while setting up the identical configuration using relationship() instead with the conflicting names would succeed, as is allowed in the case of a concrete mapping. fixes #3630
* - The ``str()`` call for :class:`.Query` will now take into accountMike Bayer2016-01-192-7/+29
| | | | | | | | | | | | the :class:`.Engine` to which the :class:`.Session` is bound, when generating the string form of the SQL, so that the actual SQL that would be emitted to the database is shown, if possible. Previously, only the engine associated with the :class:`.MetaData` to which the mappings are associated would be used, if present. If no bind can be located either on the :class:`.Session` or on the :class:`.MetaData` to which the mappings are associated, then the "default" dialect is used to render the SQL, as was the case previously. fixes #3081
* - Fixed bug where some exception re-raise scenarios would attachMike Bayer2016-01-181-12/+12
| | | | | | | | the exception to itself as the "cause"; while the Python 3 interpreter is OK with this, it could cause endless loops in iPython. fixes #3625 - add tests for reraise, raise_from_cause - raise_from_cause is the same on py2k/3k, use just one function
* - 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
* - fix some old verbiage that refers to text() as an "implicit" thingMike Bayer2016-01-141-8/+7
| | | | | for SQL fragments; we've deprecated that in 1.0 and its a good idea to document like this for 0.9 as well.

* - 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
