Update Flask-SQLAlchemy from 2.4.4 to 3.1.1.

Changelog ### 3.1.1 ``` ------------- Released 2023-09-11 - Deprecate the ``__version__`` attribute. Use feature detection, or ``importlib.metadata.version("flask-sqlalchemy")``, instead. :issue:`5230` ``` ### 3.1.0 ``` ------------- Released 2023-09-11 - Drop support for Python 3.7. :pr:`1251` - Add support for the SQLAlchemy 2.x API via ``model_class`` parameter. :issue:`1140` - Bump minimum version of SQLAlchemy to 2.0.16. - Remove previously deprecated code. - Pass extra keyword arguments from ``get_or_404`` to ``session.get``. :issue:`1149` - Fix bug with finding right bind key for clause statements. :issue:`1211` ``` ### 3.0.5 ``` ------------- Released 2023-06-21 - ``Pagination.next()`` enforces ``max_per_page``. :issue:`1201` - Improve type hint for ``get_or_404`` return value to be non-optional. :pr:`1226` ``` ### 3.0.4 ``` ------------- Released 2023-06-19 - Fix type hint for ``get_or_404`` return value. :pr:`1208` - Fix type hints for pyright (used by VS Code Pylance extension). :issue:`1205` ``` ### 3.0.3 ``` ------------- Released 2023-01-31 - Show helpful errors when mistakenly using multiple ``SQLAlchemy`` instances for the same app, or without calling ``init_app``. :pr:`1151` - Fix issue with getting the engine associated with a model that uses polymorphic table inheritance. :issue:`1155` ``` ### 3.0.2 ``` ------------- Released 2022-10-14 - Update compatibility with SQLAlchemy 2. :issue:`1122` ``` ### 3.0.1 ``` ------------- Released 2022-10-11 - Export typing information instead of using external typeshed definitions. :issue:`1112` - If default engine options are set, but ``SQLALCHEMY_DATABASE_URI`` is not set, an invalid default bind will not be configured. :issue:`1117` ``` ### 3.0.0 ``` ------------- Released 2022-10-04 - Drop support for Python 2, 3.4, 3.5, and 3.6. - Bump minimum version of Flask to 2.2. - Bump minimum version of SQLAlchemy to 1.4.18. - Remove previously deprecated code. - The session is scoped to the current app context instead of the thread. This requires that an app context is active. This ensures that the session is cleaned up after every request. - An active Flask application context is always required to access ``session`` and ``engine``, regardless of if an application was passed to the constructor. :issue:`508, 944` - Different bind keys use different SQLAlchemy ``MetaData`` registries, allowing tables in different databases to have the same name. Bind keys are stored and looked up on the resulting metadata rather than the model or table. - ``SQLALCHEMY_DATABASE_URI`` does not default to ``sqlite:///:memory:``. An error is raised if neither it nor ``SQLALCHEMY_BINDS`` define any engines. :pr:`731` - Configuring SQLite with a relative path is relative to ``app.instance_path`` instead of ``app.root_path``. The instance folder is created if necessary. :issue:`462` - Added ``get_or_404``, ``first_or_404``, ``one_or_404``, and ``paginate`` methods to the extension object. These use SQLAlchemy's preferred ``session.execute(select())`` pattern instead of the legacy query interface. :issue:`1088` - Setup methods that create the engines and session are renamed with a leading underscore. They are considered internal interfaces which may change at any time. - All parameters to ``SQLAlchemy`` except ``app`` are keyword-only. - Renamed the ``bind`` parameter to ``bind_key`` and removed the ``app`` parameter from various ``SQLAlchemy`` methods. - The extension object uses ``__getattr__`` to alias names from the SQLAlchemy package, rather than copying them as attributes. - The extension object is stored directly as ``app.extensions["sqlalchemy"]``. :issue:`698` - The session class can be customized by passing the ``class_`` key in the ``session_options`` parameter. :issue:`327` - ``SignallingSession`` is renamed to ``Session``. - ``Session.get_bind`` more closely matches the base implementation. - Model classes and the ``db`` instance are available without imports in ``flask shell``. :issue:`1089` - The ``CamelCase`` to ``snake_case`` table name converter handles more patterns correctly. If model that was already created in the database changed, either use Alembic to rename the table, or set ``__tablename__`` to keep the old name. :issue:`406` - ``Model`` ``repr`` distinguishes between transient and pending instances. :issue:`967` - A custom model class can implement ``__init_subclass__`` with class parameters. :issue:`1002` - ``db.Table`` is a subclass instead of a function. - The ``engine_options`` parameter is applied as defaults before per-engine configuration. - ``SQLALCHEMY_BINDS`` values can either be an engine URL, or a dict of engine options including URL, for each bind. ``SQLALCHEMY_DATABASE_URI`` and ``SQLALCHEMY_ENGINE_OPTIONS`` correspond to the ``None`` key and take precedence. :issue:`783` - Engines are created when calling ``init_app`` rather than the first time they are accessed. :issue:`698` - ``db.engines`` exposes the map of bind keys to engines for the current app. - ``get_engine``, ``get_tables_for_bind``, and ``get_binds`` are deprecated. - SQLite driver-level URIs that look like ``sqlite:///file:name.db?uri=true`` are supported. :issue:`998, 1045` - SQLite engines do not use ``NullPool`` if ``pool_size`` is 0. - MySQL engines use the "utf8mb4" charset by default. :issue:`875` - MySQL engines do not set ``pool_size`` to 10. - MySQL engines don't set a default for ``pool_recycle`` if not using a queue pool. :issue:`803` - ``Query`` is renamed from ``BaseQuery``. - Added ``Query.one_or_404``. - The query class is applied to ``backref`` in ``relationship``. :issue:`417` - Creating ``Pagination`` objects manually is no longer a public API. They should be created with ``db.paginate`` or ``query.paginate``. :issue:`1088` - ``Pagination.iter_pages`` and ``Query.paginate`` parameters are keyword-only. - ``Pagination`` is iterable, iterating over its items. :issue:`70` - Pagination count query is more efficient. - ``Pagination.iter_pages`` is more efficient. :issue:`622` - ``Pagination.iter_pages`` ``right_current`` parameter is inclusive. - Pagination ``per_page`` cannot be 0. :issue:`1091` - Pagination ``max_per_page`` defaults to 100. :issue:`1091` - Added ``Pagination.first`` and ``last`` properties, which give the number of the first and last item on the page. :issue:`567` - ``SQLALCHEMY_RECORD_QUERIES`` is disabled by default, and is not enabled automatically with ``app.debug`` or ``app.testing``. :issue:`1092` - ``get_debug_queries`` is renamed to ``get_recorded_queries`` to better match the config and functionality. - Recorded query info is a dataclass instead of a tuple. The ``context`` attribute is renamed to ``location``. Finding the location uses a more inclusive check. - ``SQLALCHEMY_TRACK_MODIFICATIONS`` is disabled by default. :pr:`727` - ``SQLALCHEMY_COMMIT_ON_TEARDOWN`` is deprecated. It can cause various design issues that are difficult to debug. Call ``db.session.commit()`` directly instead. :issue:`216` ``` ### 2.5.1 ``` ------------- Released 2021-03-18 - Fix compatibility with Python 2.7. ``` ### 2.5.0 ``` ------------- Released 2021-03-18 - Update to support SQLAlchemy 1.4. - SQLAlchemy ``URL`` objects are immutable. Some internal methods have changed to return a new URL instead of ``None``. :issue:`885` ```

Update SQLAlchemy from 1.3.20 to 2.0.25.

Changelog ### 2.0.25 ``` :released: January 2, 2024 .. change:: :tags: oracle, asyncio :tickets: 10679 Added support for :ref:`oracledb` in asyncio mode, using the newly released version of the ``oracledb`` DBAPI that includes asyncio support. For the 2.0 series, this is a preview release, where the current implementation does not yet have include support for :meth:`_asyncio.AsyncConnection.stream`. Improved support is planned for the 2.1 release of SQLAlchemy. .. change:: :tags: bug, orm :tickets: 10800 Fixed issue where when making use of the :paramref:`_orm.relationship.post_update` feature at the same time as using a mapper version_id_col could lead to a situation where the second UPDATE statement emitted by the post-update feature would fail to make use of the correct version identifier, assuming an UPDATE was already emitted in that flush which had already bumped the version counter. .. change:: :tags: bug, typing :tickets: 10801, 10818 Fixed regressions caused by typing added to the ``sqlalchemy.sql.functions`` module in version 2.0.24, as part of :ticket:`6810`: * Further enhancements to pep-484 typing to allow SQL functions from :attr:`_sql.func` derived elements to work more effectively with ORM-mapped attributes (:ticket:`10801`) * Fixed the argument types passed to functions so that literal expressions like strings and ints are again interpreted correctly (:ticket:`10818`) .. change:: :tags: usecase, orm :tickets: 10807 Added preliminary support for Python 3.12 pep-695 type alias structures, when resolving custom type maps for ORM Annotated Declarative mappings. .. change:: :tags: bug, orm :tickets: 10815 Fixed issue where ORM Annotated Declarative would mis-interpret the left hand side of a relationship without any collection specified as uselist=True if the left type were given as a class and not a string, without using future-style annotations. .. change:: :tags: bug, sql :tickets: 10817 Improved compilation of :func:`_sql.any_` / :func:`_sql.all_` in the context of a negation of boolean comparison, will now render ``NOT (expr)`` rather than reversing the equality operator to not equals, allowing finer-grained control of negations for these non-typical operators. .. changelog:: ``` ### 2.0.24 ``` :released: December 28, 2023 .. change:: :tags: bug, orm :tickets: 10597 Fixed issue where use of :func:`_orm.foreign` annotation on a non-initialized :func:`_orm.mapped_column` construct would produce an expression without a type, which was then not updated at initialization time of the actual column, leading to issues such as relationships not determining ``use_get`` appropriately. .. change:: :tags: bug, schema :tickets: 10654 Fixed issue where error reporting for unexpected schema item when creating objects like :class:`_schema.Table` would incorrectly handle an argument that was itself passed as a tuple, leading to a formatting error. The error message has been modernized to use f-strings. .. change:: :tags: bug, engine :tickets: 10662 Fixed URL-encoding of the username and password components of :class:`.engine.URL` objects when converting them to string using the :meth:`_engine.URL.render_as_string` method, by using Python standard library ``urllib.parse.quote`` while allowing for plus signs and spaces to remain unchanged as supported by SQLAlchemy's non-standard URL parsing, rather than the legacy home-grown routine from many years ago. Pull request courtesy of Xavier NUNN. .. change:: :tags: bug, orm :tickets: 10668 Improved the error message produced when the unit of work process sets the value of a primary key column to NULL due to a related object with a dependency rule on that column being deleted, to include not just the destination object and column name but also the source column from which the NULL value is originating. Pull request courtesy Jan Vollmer. .. change:: :tags: bug, postgresql :tickets: 10717 Adjusted the asyncpg dialect such that when the ``terminate()`` method is used to discard an invalidated connection, the dialect will first attempt to gracefully close the connection using ``.close()`` with a timeout, if the operation is proceeding within an async event loop context only. This allows the asyncpg driver to attend to finalizing a ``TimeoutError`` including being able to close a long-running query server side, which otherwise can keep running after the program has exited. .. change:: :tags: bug, orm :tickets: 10732 Modified the ``__init_subclass__()`` method used by :class:`_orm.MappedAsDataclass`, :class:`_orm.DeclarativeBase` and :class:`_orm.DeclarativeBaseNoMeta` to accept arbitrary ``**kw`` and to propagate them to the ``super()`` call, allowing greater flexibility in arranging custom superclasses and mixins which make use of ``__init_subclass__()`` keyword arguments. Pull request courtesy Michael Oliver. .. change:: :tags: bug, tests :tickets: 10747 Improvements to the test suite to further harden its ability to run when Python ``greenlet`` is not installed. There is now a tox target that includes the token "nogreenlet" that will run the suite with greenlet not installed (note that it still temporarily installs greenlet as part of the tox config, however). .. change:: :tags: bug, sql :tickets: 10753 Fixed issue in stringify for SQL elements, where a specific dialect is not passed, where a dialect-specific element such as the PostgreSQL "on conflict do update" construct is encountered and then fails to provide for a stringify dialect with the appropriate state to render the construct, leading to internal errors. .. change:: :tags: bug, sql Fixed issue where stringifying or compiling a :class:`.CTE` that was against a DML construct such as an :func:`_sql.insert` construct would fail to stringify, due to a mis-detection that the statement overall is an INSERT, leading to internal errors. .. change:: :tags: bug, orm :tickets: 10776 Ensured the use case of :class:`.Bundle` objects used in the ``returning()`` portion of ORM-enabled INSERT, UPDATE and DELETE statements is tested and works fully. This was never explicitly implemented or tested previously and did not work correctly in the 1.4 series; in the 2.0 series, ORM UPDATE/DELETE with WHERE criteria was missing an implementation method preventing :class:`.Bundle` objects from working. .. change:: :tags: bug, orm :tickets: 10784 Fixed 2.0 regression in :class:`.MutableList` where a routine that detects sequences would not correctly filter out string or bytes instances, making it impossible to assign a string value to a specific index (while non-sequence values would work fine). .. change:: :tags: change, asyncio The ``async_fallback`` dialect argument is now deprecated, and will be removed in SQLAlchemy 2.1. This flag has not been used for SQLAlchemy's test suite for some time. asyncio dialects can still run in a synchronous style by running code within a greenlet using :func:`_util.greenlet_spawn`. .. change:: :tags: bug, typing :tickets: 6810 Completed pep-484 typing for the ``sqlalchemy.sql.functions`` module. :func:`_sql.select` constructs made against ``func`` elements should now have filled-in return types. .. changelog:: ``` ### 2.0.23 ``` :released: November 2, 2023 .. change:: :tags: bug, oracle :tickets: 10509 Fixed issue in :class:`.Interval` datatype where the Oracle implementation was not being used for DDL generation, leading to the ``day_precision`` and ``second_precision`` parameters to be ignored, despite being supported by this dialect. Pull request courtesy Indivar. .. change:: :tags: bug, orm :tickets: 10516 Fixed issue where the ``__allow_unmapped__`` directive failed to allow for legacy :class:`.Column` / :func:`.deferred` mappings that nonetheless had annotations such as ``Any`` or a specific type without ``Mapped[]`` as their type, without errors related to locating the attribute name. .. change:: :tags: bug, mariadb :tickets: 10056 Adjusted the MySQL / MariaDB dialects to default a generated column to NULL when using MariaDB, if :paramref:`_schema.Column.nullable` was not specified with an explicit ``True`` or ``False`` value, as MariaDB does not support the "NOT NULL" phrase with a generated column. Pull request courtesy Indivar. .. change:: :tags: bug, mariadb, regression :tickets: 10505 Established a workaround for what seems to be an intrinsic issue across MySQL/MariaDB drivers where a RETURNING result for DELETE DML which returns no rows using SQLAlchemy's "empty IN" criteria fails to provide a cursor.description, which then yields result that returns no rows, leading to regressions for the ORM that in the 2.0 series uses RETURNING for bulk DELETE statements for the "synchronize session" feature. To resolve, when the specific case of "no description when RETURNING was given" is detected, an "empty result" with a correct cursor description is generated and used in place of the non-working cursor. .. change:: :tags: bug, orm :tickets: 10570 Fixed caching bug where using the :func:`_orm.with_expression` construct in conjunction with loader options :func:`_orm.selectinload`, :func:`_orm.lazyload` would fail to substitute bound parameter values correctly on subsequent caching runs. .. change:: :tags: usecase, mssql :tickets: 6521 Added support for the ``aioodbc`` driver implemented for SQL Server, which builds on top of the pyodbc and general aio* dialect architecture. .. seealso:: :ref:`mssql_aioodbc` - in the SQL Server dialect documentation. .. change:: :tags: bug, sql :tickets: 10535 Added compiler-level None/NULL handling for the "literal processors" of all datatypes that include literal processing, that is, where a value is rendered inline within a SQL statement rather than as a bound parameter, for all those types that do not feature explicit "null value" handling. Previously this behavior was undefined and inconsistent. .. change:: :tags: usecase, orm :tickets: 10575 Implemented the :paramref:`_orm.Session.bulk_insert_mappings.render_nulls` parameter for new style bulk ORM inserts, allowing ``render_nulls=True`` as an execution option. This allows for bulk ORM inserts with a mixture of ``None`` values in the parameter dictionaries to use a single batch of rows for a given set of dicationary keys, rather than breaking up into batches that omit the NULL columns from each INSERT. .. seealso:: :ref:`orm_queryguide_insert_null_params` .. change:: :tags: bug, postgresql :tickets: 10479 Fixed 2.0 regression caused by :ticket:`7744` where chains of expressions involving PostgreSQL JSON operators combined with other operators such as string concatenation would lose correct parenthesization, due to an implementation detail specific to the PostgreSQL dialect. .. change:: :tags: bug, postgresql :tickets: 10532 Fixed SQL handling for "insertmanyvalues" when using the :class:`.postgresql.BIT` datatype with the asyncpg backend. The :class:`.postgresql.BIT` on asyncpg apparently requires the use of an asyncpg-specific ``BitString`` type which is currently exposed when using this DBAPI, making it incompatible with other PostgreSQL DBAPIs that all work with plain bitstrings here. A future fix in version 2.1 will normalize this datatype across all PG backends. Pull request courtesy Sören Oldag. .. change:: :tags: usecase, sql :tickets: 9737 Implemented "literal value processing" for the :class:`.Interval` datatype for both the PostgreSQL and Oracle dialects, allowing literal rendering of interval values. Pull request courtesy Indivar Mishra. .. change:: :tags: bug, oracle :tickets: 10470 Fixed issue where the cx_Oracle dialect claimed to support a lower cx_Oracle version (7.x) than was actually supported in practice within the 2.0 series of SQLAlchemy. The dialect imports symbols that are only in cx_Oracle 8 or higher, so runtime dialect checks as well as setup.cfg requirements have been updated to reflect this compatibility. .. change:: :tags: sql Removed unused placeholder method :meth:`.TypeEngine.compare_against_backend` This method was used by very old versions of Alembic. See https://github.com/sqlalchemy/alembic/issues/1293 for details. .. change:: :tags: bug, orm :tickets: 10472 Fixed bug in ORM annotated declarative where using a ``ClassVar`` that nonetheless referred in some way to an ORM mapped class name would fail to be interpreted as a ``ClassVar`` that's not mapped. .. change:: :tags: bug, asyncio :tickets: 10421 Fixed bug with method :meth:`_asyncio.AsyncSession.close_all` that was not working correctly. Also added function :func:`_asyncio.close_all_sessions` that's the equivalent of :func:`_orm.close_all_sessions`. Pull request courtesy of Bryan不可思议. .. changelog:: ``` ### 2.0.22 ``` :released: October 12, 2023 .. change:: :tags: bug, orm :tickets: 10369, 10046 Fixed a wide range of :func:`_orm.mapped_column` parameters that were not being transferred when using the :func:`_orm.mapped_column` object inside of a pep-593 ``Annotated`` object, including :paramref:`_orm.mapped_column.sort_order`, :paramref:`_orm.mapped_column.deferred`, :paramref:`_orm.mapped_column.autoincrement`, :paramref:`_orm.mapped_column.system`, :paramref:`_orm.mapped_column.info` etc. Additionally, it remains not supported to have dataclass arguments, such as :paramref:`_orm.mapped_column.kw_only`, :paramref:`_orm.mapped_column.default_factory` etc. indicated within the :func:`_orm.mapped_column` received by ``Annotated``, as this is not supported with pep-681 Dataclass Transforms. A warning is now emitted when these parameters are used within ``Annotated`` in this way (and they continue to be ignored). .. change:: :tags: bug, orm :tickets: 10459 Fixed issue where calling :meth:`_engine.Result.unique` with a new-style :func:`.select` query in the ORM, where one or more columns yields values that are of "unknown hashability", typically when using JSON functions like ``func.json_build_object()`` without providing a type, would fail internally when the returned values were not actually hashable. The behavior is repaired to test the objects as they are received for hashability in this case, raising an informative error message if not. Note that for values of "known unhashability", such as when the :class:`_types.JSON` or :class:`_types.ARRAY` types are used directly, an informative error message was already raised. The "hashabiltiy testing" fix here is applied to legacy :class:`.Query` as well, however in the legacy case, :meth:`_engine.Result.unique` is used for nearly all queries, so no new warning is emitted here; the legacy behavior of falling back to using ``id()`` in this case is maintained, with the improvement that an unknown type that turns out to be hashable will now be uniqufied, whereas previously it would not. .. change:: :tags: bug, orm :tickets: 10453 Fixed regression in recently revised "insertmanyvalues" feature (likely issue :ticket:`9618`) where the ORM would inadvertently attempt to interpret a non-RETURNING result as one with RETURNING, in the case where the ``implicit_returning=False`` parameter were applied to the mapped :class:`.Table`, indicating that "insertmanyvalues" cannot be used if the primary key values are not provided. .. change:: :tags: bug, engine Fixed issue within some dialects where the dialect could incorrectly return an empty result set for an INSERT statement that does not actually return rows at all, due to artfacts from pre- or post-fetching the primary key of the row or rows still being present. Affected dialects included asyncpg, all mssql dialects. .. change:: :tags: bug, typing :tickets: 10451 Fixed typing issue where the argument list passed to :class:`.Values` was too-restrictively tied to ``List`` rather than ``Sequence``. Pull request courtesy Iuri de Silvio. .. change:: :tags: bug, orm :tickets: 10365 Fixed bug where ORM :func:`_orm.with_loader_criteria` would not apply itself to a :meth:`_sql.Select.join` where the ON clause were given as a plain SQL comparison, rather than as a relationship target or similar. .. change:: :tags: bug, sql :tickets: 10408 Fixed issue where referring to a FROM entry in the SET clause of an UPDATE statement would not include it in the FROM clause of the UPDATE statement, if that entry were nowhere else in the statement; this occurs currently for CTEs that were added using :meth:`.Update.add_cte` to provide the desired CTE at the top of the statement. .. change:: :tags: bug, mariadb :tickets: 10396 Modified the mariadb-connector driver to pre-load the ``cursor.rowcount`` value for all queries, to suit tools such as Pandas that hardcode to calling :attr:`.Result.rowcount` in this way. SQLAlchemy normally pre-loads ``cursor.rowcount`` only for UPDATE/DELETE statements and otherwise passes through to the DBAPI where it can return -1 if no value is available. However, mariadb-connector does not support invoking ``cursor.rowcount`` after the cursor itself is closed, raising an error instead. Generic test support has been added to ensure all backends support the allowing :attr:`.Result.rowcount` to succceed (that is, returning an integer value with -1 for "not available") after the result is closed. .. change:: :tags: bug, mariadb Additional fixes for the mariadb-connector dialect to support UUID data values in the result in INSERT..RETURNING statements. .. change:: :tags: bug, mssql :tickets: 10458 Fixed bug where the rule that prevents ORDER BY from emitting within subqueries on SQL Server was not being disabled in the case where the :meth:`.select.fetch` method were used to limit rows in conjunction with WITH TIES or PERCENT, preventing valid subqueries with TOP / ORDER BY from being used. .. change:: :tags: bug, sql :tickets: 10443 Fixed 2.0 regression where the :class:`.DDL` construct would no longer ``__repr__()`` due to the removed ``on`` attribute not being accommodated. Pull request courtesy Iuri de Silvio. .. change:: :tags: orm, usecase :tickets: 10202 Added method :meth:`_orm.Session.get_one` that behaves like :meth:`_orm.Session.get` but raises an exception instead of returning ``None`` if no instance was found with the provided primary key. Pull request courtesy of Carlos Sousa. .. change:: :tags: asyncio, bug Fixed the :paramref:`_asyncio.AsyncSession.get.execution_options` parameter which was not being propagated to the underlying :class:`_orm.Session` and was instead being ignored. .. change:: :tags: bug, orm :tickets: 10412 Fixed issue where :class:`.Mapped` symbols like :class:`.WriteOnlyMapped` and :class:`.DynamicMapped` could not be correctly resolved when referenced as an element of a sub-module in the given annotation, assuming string-based or "future annotations" style annotations. .. change:: :tags: bug, engine :tickets: 10414 Fixed issue where under some garbage collection / exception scenarios the connection pool's cleanup routine would raise an error due to an unexpected set of state, which can be reproduced under specific conditions. .. change:: :tags: bug, typing Updates to the codebase to support Mypy 1.6.0. .. change:: :tags: usecase, orm :tickets: 7787 Added an option to permanently close sessions. Set to ``False`` the new parameter :paramref:`_orm.Session.close_resets_only` will prevent a :class:`_orm.Session` from performing any other operation after :meth:`_orm.Session.close` has been called. Added new method :meth:`_orm.Session.reset` that will reset a :class:`_orm.Session` to its initial state. This is an alias of :meth:`_orm.Session.close`, unless :paramref:`_orm.Session.close_resets_only` is set to ``False``. .. change:: :tags: orm, bug :tickets: 10385 Fixed issue with ``__allow_unmapped__`` declarative option where types that were declared using collection types such as ``list[SomeClass]`` vs. the typing construct ``List[SomeClass]`` would fail to be recognized correctly. Pull request courtesy Pascal Corpet. .. changelog:: ``` ### 2.0.21 ``` :released: September 18, 2023 .. change:: :tags: bug, sql :tickets: 9610 Adjusted the operator precedence for the string concatenation operator to be equal to that of string matching operators, such as :meth:`.ColumnElement.like`, :meth:`.ColumnElement.regexp_match`, :meth:`.ColumnElement.match`, etc., as well as plain ``==`` which has the same precedence as string comparison operators, so that parenthesis will be applied to a string concatenation expression that follows a string match operator. This provides for backends such as PostgreSQL where the "regexp match" operator is apparently of higher precedence than the string concatenation operator. .. change:: :tags: bug, sql :tickets: 10342 Qualified the use of ``hashlib.md5()`` within the DDL compiler, which is used to generate deterministic four-character suffixes for long index and constraint names in DDL statements, to include the Python 3.9+ ``usedforsecurity=False`` parameter so that Python interpreters built for restricted environments such as FIPS do not consider this call to be related to security concerns. .. change:: :tags: bug, postgresql :tickets: 10226 Fixed regression which appeared in 2.0 due to :ticket:`8491` where the revised "ping" used for PostgreSQL dialects when the :paramref:`_sa.create_engine.pool_pre_ping` parameter is in use would interfere with the use of asyncpg with PGBouncer "transaction" mode, as the multiple PostgreSQL commands emitted by asnycpg could be broken out among multiple connections leading to errors, due to the lack of any transaction around this newly revised "ping". The ping is now invoked within a transaction, in the same way that is implicit with all other backends that are based on the pep-249 DBAPI; this guarantees that the series of PG commands sent by asyncpg for this command are invoked on the same backend connection without it jumping to a different connection mid-command. The transaction is not used if the asyncpg dialect is used in "AUTOCOMMIT" mode, which remains incompatible with pgbouncer transaction mode. .. change:: :tags: bug, orm :tickets: 10279 Adjusted the ORM's interpretation of the "target" entity used within :class:`.Update` and :class:`.Delete` to not interfere with the target "from" object passed to the statement, such as when passing an ORM-mapped :class:`_orm.aliased` construct that should be maintained within a phrase like "UPDATE FROM". Cases like ORM session synchonize using "SELECT" statements such as with MySQL/ MariaDB will still have issues with UPDATE/DELETE of this form so it's best to disable synchonize_session when using DML statements of this type. .. change:: :tags: bug, orm :tickets: 10348 Added new capability to the :func:`_orm.selectin_polymorphic` loader option which allows other loader options to be bundled as siblings, referring to one of its subclasses, within the sub-options of parent loader option. Previously, this pattern was only supported if the :func:`_orm.selectin_polymorphic` were at the top level of the options for the query. See new documentation section for example. As part of this change, improved the behavior of the :meth:`_orm.Load.selectin_polymorphic` method / loader strategy so that the subclass load does not load most already-loaded columns from the parent table, when the option is used against a class that is already being relationship-loaded. Previously, the logic to load only the subclass columns worked only for a top level class load. .. seealso:: :ref:`polymorphic_selectin_as_loader_option_target_plus_opts` .. change:: :tags: bug, typing :tickets: 10264, 9284 Fixed regression introduced in 2.0.20 via :ticket:`9600` fix which attempted to add more formal typing to :paramref:`_schema.MetaData.naming_convention`. This change prevented basic naming convention dictionaries from passing typing and has been adjusted so that a plain dictionary of strings for keys as well as dictionaries that use constraint types as keys or a mix of both, are again accepted. As part of this change, lesser used forms of the naming convention dictionary are also typed, including that it currently allows for ``Constraint`` type objects as keys as well. .. change:: :tags: usecase, typing :tickets: 10288 Made the contained type for :class:`.Mapped` covariant; this is to allow greater flexibility for end-user typing scenarios, such as the use of protocols to represent particular mapped class structures that are passed to other functions. As part of this change, the contained type was also made covariant for dependent and related types such as :class:`_orm.base.SQLORMOperations`, :class:`_orm.WriteOnlyMapped`, and :class:`_sql.SQLColumnExpression`. Pull request courtesy Roméo Després. .. change:: :tags: bug, engine :tickets: 10275 Fixed a series of reflection issues affecting the PostgreSQL, MySQL/MariaDB, and SQLite dialects when reflecting foreign key constraints where the target column contained parenthesis in one or both of the table name or column name. .. change:: :tags: bug, sql :tickets: 10280 The :class:`.Values` construct will now automatically create a proxy (i.e. a copy) of a :class:`_sql.column` if the column were already associated with an existing FROM clause. This allows that an expression like ``values_obj.c.colname`` will produce the correct FROM clause even in the case that ``colname`` was passed as a :class:`_sql.column` that was already used with a previous :class:`.Values` or other table construct. Originally this was considered to be a candidate for an error condition, however it's likely this pattern is already in widespread use so it's now added to support. .. change:: :tags: bug, setup :tickets: 10321 Fixed very old issue where the full extent of SQLAlchemy modules, including ``sqlalchemy.testing.fixtures``, could not be imported outside of a pytest run. This suits inspection utilities such as ``pkgutil`` that attempt to import all installed modules in all packages. .. change:: :tags: usecase, sql :tickets: 10269 Adjusted the :class:`_types.Enum` datatype to accept an argument of ``None`` for the :paramref:`_types.Enum.length` parameter, resulting in a VARCHAR or other textual type with no length in the resulting DDL. This allows for new elements of any length to be added to the type after it exists in the schema. Pull request courtesy Eugene Toder. .. change:: :tags: bug, typing :tickets: 9878 Fixed the type annotation for ``__class_getitem__()`` as applied to the ``Visitable`` class at the base of expression constructs to accept ``Any`` for a key, rather than ``str``, which helps with some IDEs such as PyCharm when attempting to write typing annotations for SQL constructs which include generic selectors. Pull request courtesy Jordan Macdonald. .. change:: :tags: bug, typing :tickets: 10353 Repaired the core "SQL element" class ``SQLCoreOperations`` to support the ``__hash__()`` method from a typing perspective, as objects like :class:`.Column` and ORM :class:`.InstrumentedAttribute` are hashable and are used as dictionary keys in the public API for the :class:`_dml.Update` and :class:`_dml.Insert` constructs. Previously, type checkers were not aware the root SQL element was hashable. .. change:: :tags: bug, typing :tickets: 10337 Fixed typing issue with :meth:`_sql.Existing.select_from` that prevented its use with ORM classes. .. change:: :tags: usecase, sql :tickets: 9873 Added new generic SQL function :class:`_functions.aggregate_strings`, which accepts a SQL expression and a decimeter, concatenating strings on multiple rows into a single aggregate value. The function is compiled on a per-backend basis, into functions such as ``group_concat(),`` ``string_agg()``, or ``LISTAGG()``. Pull request courtesy Joshua Morris. .. change:: :tags: typing, bug :tickets: 10131 Update type annotations for ORM loading options, restricting them to accept only `"*"` instead of any string for string arguments. Pull request courtesy Janek Nouvertné. .. changelog:: ``` ### 2.0.20 ``` :released: August 15, 2023 .. change:: :tags: bug, orm :tickets: 10169 Fixed issue where the ORM's generation of a SELECT from a joined inheritance model with same-named columns in superclass and subclass would somehow not send the correct list of column names to the :class:`.CTE` construct, when the RECURSIVE column list were generated. .. change:: :tags: bug, typing :tickets: 9185 Typing improvements: * :class:`.CursorResult` is returned for some forms of :meth:`_orm.Session.execute` where DML without RETURNING is used * fixed type for :paramref:`_orm.Query.with_for_update.of` parameter within :meth:`_orm.Query.with_for_update` * improvements to ``_DMLColumnArgument`` type used by some DML methods to pass column expressions * Add overload to :func:`_sql.literal` so that it is inferred that the return type is ``BindParameter[NullType]`` where :paramref:`_sql.literal.type_` param is None * Add overloads to :meth:`_sql.ColumnElement.op` so that the inferred type when :paramref:`_sql.ColumnElement.op.return_type` is not provided is ``Callable[[Any], BinaryExpression[Any]]`` * Add missing overload to :meth:`_sql.ColumnElement.__add__` Pull request courtesy Mehdi Gmira. .. change:: :tags: usecase, orm :tickets: 10192 Implemented the "RETURNING '*'" use case for ORM enabled DML statements. This will render in as many cases as possible and return the unfiltered result set, however is not supported for multi-parameter "ORM bulk INSERT" statements that have specific column rendering requirements. .. change:: :tags: bug, typing :tickets: 10182 Fixed issue in :class:`_orm.Session` and :class:`_asyncio.AsyncSession` methods such as :meth:`_orm.Session.connection` where the :paramref:`_orm.Session.connection.execution_options` parameter were hardcoded to an internal type that is not user-facing. .. change:: :tags: orm, bug :tickets: 10231 Fixed fairly major issue where execution options passed to :meth:`_orm.Session.execute`, as well as execution options local to the ORM executed statement itself, would not be propagated along to eager loaders such as that of :func:`_orm.selectinload`, :func:`_orm.immediateload`, and :meth:`_orm.subqueryload`, making it impossible to do things such as disabling the cache for a single statement or using ``schema_translate_map`` for a single statement, as well as the use of user-custom execution options. A change has been made where **all** user-facing execution options present for :meth:`_orm.Session.execute` will be propagated along to additional loaders. As part of this change, the warning for "excessively deep" eager loaders leading to caching being disabled can be silenced on a per-statement basis by sending ``execution_options={"compiled_cache": None}`` to :meth:`_orm.Session.execute`, which will disable caching for the full series of statements within that scope. .. change:: :tags: usecase, asyncio :tickets: 9698 Added new methods :meth:`_asyncio.AsyncConnection.aclose` as a synonym for :meth:`_asyncio.AsyncConnection.close` and :meth:`_asyncio.AsyncSession.aclose` as a synonym for :meth:`_asyncio.AsyncSession.close` to the :class:`_asyncio.AsyncConnection` and :class:`_asyncio.AsyncSession` objects, to provide compatibility with Python standard library ``contextlib.aclosing`` construct. Pull request courtesy Grigoriev Semyon. .. change:: :tags: bug, orm :tickets: 10124 Fixed issue where internal cloning used by the ORM for expressions like :meth:`_orm.relationship.Comparator.any` to produce correlated EXISTS constructs would interfere with the "cartesian product warning" feature of the SQL compiler, leading the SQL compiler to warn when all elements of the statement were correctly joined. .. change:: :tags: orm, bug :tickets: 10139 Fixed issue where the ``lazy="immediateload"`` loader strategy would place an internal loading token into the ORM mapped attribute under circumstances where the load should not occur, such as in a recursive self-referential load. As part of this change, the ``lazy="immediateload"`` strategy now honors the :paramref:`_orm.relationship.join_depth` parameter for self-referential eager loads in the same way as that of other eager loaders, where leaving it unset or set at zero will lead to a self-referential immediateload not occurring, setting it to a value of one or greater will immediateload up until that given depth. .. change:: :tags: bug, orm :tickets: 10175 Fixed issue where dictionary-based collections such as :func:`_orm.attribute_keyed_dict` did not fully pickle/unpickle correctly, leading to issues when attempting to mutate such a collection after unpickling. .. change:: :tags: bug, orm :tickets: 10125 Fixed issue where chaining :func:`_orm.load_only` or other wildcard use of :func:`_orm.defer` from another eager loader using a :func:`_orm.aliased` against a joined inheritance subclass would fail to take effect for columns local to the superclass. .. change:: :tags: bug, orm :tickets: 10167 Fixed issue where an ORM-enabled :func:`_sql.select` construct would not render any CTEs added only via the :meth:`_sql.Select.add_cte` method that were not otherwise referenced in the statement. .. change:: :tags: bug, examples The dogpile_caching examples have been updated for 2.0 style queries. Within the "caching query" logic itself there is one conditional added to differentiate between ``Query`` and ``select()`` when performing an invalidation operation. .. change:: :tags: typing, usecase :tickets: 10173 Added new typing only utility functions :func:`.Nullable` and :func:`.NotNullable` to type a column or ORM class as, respectively, nullable or not nullable. These function are no-op at runtime, returning the input unchanged. .. change:: :tags: bug, engine :tickets: 10147 Fixed critical issue where setting :paramref:`_sa.create_engine.isolation_level` to ``AUTOCOMMIT`` (as opposed to using the :meth:`_engine.Engine.execution_options` method) would fail to restore "autocommit" to a pooled connection if an alternate isolation level were temporarily selected using :paramref:`_engine.Connection.execution_options.isolation_level`. .. changelog:: ``` ### 2.0.19 ``` :released: July 15, 2023 .. change:: :tags: bug, orm :tickets: 10089 Fixed issue where setting a relationship collection directly, where an object in the new collection were already present, would not trigger a cascade event for that object, leading to it not being added to the :class:`_orm.Session` if it were not already present. This is similar in nature to :ticket:`6471` and is a more apparent issue due to the removal of ``cascade_backrefs`` in the 2.0 series. The :meth:`_orm.AttributeEvents.append_wo_mutation` event added as part of :ticket:`6471` is now also emitted for existing members of a collection that are present in a bulk set of that same collection. .. change:: :tags: bug, engine :tickets: 10093 Renamed :attr:`_result.Row.t` and :meth:`_result.Row.tuple` to :attr:`_result.Row._t` and :meth:`_result.Row._tuple`; this is to suit the policy that all methods and pre-defined attributes on :class:`.Row` should be in the style of Python standard library ``namedtuple`` where all fixed names have a leading underscore, to avoid name conflicts with existing column names. The previous method/attribute is now deprecated and will emit a deprecation warning. .. change:: :tags: bug, postgresql :tickets: 10069 Fixed regression caused by improvements to PostgreSQL URL parsing in :ticket:`10004` where "host" query string arguments that had colons in them, to support various third party proxy servers and/or dialects, would not parse correctly as these were evaluted as ``host:port`` combinations. Parsing has been updated to consider a colon as indicating a ``host:port`` value only if the hostname contains only alphanumeric characters with dots or dashes only (e.g. no slashes), followed by exactly one colon followed by an all-integer token of zero or more integers. In all other cases, the full string is taken as a host. .. change:: :tags: bug, engine :tickets: 10079 Added detection for non-string, non-:class:`_engine.URL` objects to the :func:`_engine.make_url` function, allowing ``ArgumentError`` to be thrown immediately, rather than causing failures later on. Special logic ensures that mock forms of :class:`_engine.URL` are allowed through. Pull request courtesy Grigoriev Semyon. .. change:: :tags: bug, orm :tickets: 10090 Fixed issue where objects that were associated with an unloaded collection via backref, but were not merged into the :class:`_orm.Session` due to the removal of ``cascade_backrefs`` in the 2.0 series, would not emit a warning that these objects were not being included in a flush, even though they were pending members of the collection; in other such cases, a warning is emitted when a collection being flushed contains non-attached objects which will be essentially discarded. The addition of the warning for backref-pending collection members establishes greater consistency with collections that may be present or non-present and possibly flushed or not flushed at different times based on different relationship loading strategies. .. change:: :tags: bug, postgresql :tickets: 10096 Fixed issue where comparisons to the :class:`_postgresql.CITEXT` datatype would cast the right side to ``VARCHAR``, leading to the right side not being interpreted as a ``CITEXT`` datatype, for the asyncpg, psycopg3 and pg80000 dialects. This led to the :class:`_postgresql.CITEXT` type being essentially unusable for practical use; this is now fixed and the test suite has been corrected to properly assert that expressions are rendered correctly. .. change:: :tags: bug, orm, regression :tickets: 10098 Fixed additional regression caused by :ticket:`9805` where more aggressive propagation of the "ORM" flag on statements could lead to an internal attribute error when embedding an ORM :class:`.Query` construct that nonetheless contained no ORM entities within a Core SQL statement, in this case ORM-enabled UPDATE and DELETE statements. .. changelog:: ``` ### 2.0.18 ``` :released: July 5, 2023 .. change:: :tags: usecase, typing :tickets: 10054 Improved typing when using standalone operator functions from ``sqlalchemy.sql.operators`` such as ``sqlalchemy.sql.operators.eq``. .. change:: :tags: usecase, mariadb, reflection :tickets: 10028 Allowed reflecting :class:`_types.UUID` columns from MariaDB. This allows Alembic to properly detect the type of such columns in existing MariaDB databases. .. change:: :tags: bug, postgresql :tickets: 9945 Added new parameter ``native_inet_types=False`` to all PostgreSQL dialects, which indicates converters used by the DBAPI to convert rows from PostgreSQL :class:`.INET` and :class:`.CIDR` columns into Python ``ipaddress`` datatypes should be disabled, returning strings instead. This allows code written to work with strings for these datatypes to be migrated to asyncpg, psycopg, or pg8000 without code changes other than adding this parameter to the :func:`_sa.create_engine` or :func:`_asyncio.create_async_engine` function call. .. seealso:: :ref:`postgresql_network_datatypes` .. change:: :tags: usecase, extensions :tickets: 10013 Added new option to :func:`.association_proxy` :paramref:`.association_proxy.create_on_none_assignment`; when an association proxy which refers to a scalar relationship is assigned the value ``None``, and the referenced object is not present, a new object is created via the creator. This was apparently an undefined behavior in the 1.2 series that was silently removed. .. change:: :tags: bug, typing :tickets: 10061 Fixed some of the typing within the :func:`_orm.aliased` construct to correctly accept a :class:`.Table` object that's been aliased with :meth:`.Table.alias`, as well as general support for :class:`.FromClause` objects to be passed as the "selectable" argument, since this is all supported. .. change:: :tags: bug, engine :tickets: 10025 Adjusted the :paramref:`_sa.create_engine.schema_translate_map` feature such that **all** schema names in the statement are now tokenized, regardless of whether or not a specific name is in the immediate schema translate map given, and to fallback to substituting the original name when the key is not in the actual schema translate map at execution time. These two changes allow for repeated use of a compiled object with schema schema_translate_maps that include or dont include various keys on each run, allowing cached SQL constructs to continue to function at runtime when schema translate maps with different sets of keys are used each time. In addition, added detection of schema_translate_map dictionaries which gain or lose a ``None`` key across calls for the same statement, which affects compilation of the statement and is not compatible with caching; an exception is raised for these scenarios. .. change:: :tags: bug, mssql, sql :tickets: 9932 Fixed issue where performing :class:`.Cast` to a
