```
==================
.. attention::
This is the last :doc:`aiohttp <index>` release tested under
Python 3.6. The 3.9 stream is dropping it from the CI and the
distribution package metadata.
Bugfixes
--------
- Increased the upper boundary of the :doc:`multidict:index` dependency
to allow for the version 6 -- by :user:`hugovk`.
It used to be limited below version 7 in :doc:`aiohttp <index>` v3.8.1 but
was lowered in v3.8.2 via :pr:`6550` and never brought back, causing
problems with dependency pins when upgrading. :doc:`aiohttp <index>` v3.8.3
fixes that by recovering the original boundary of ``< 7``.

### 3.8.1
```
==================
Bugfixes
--------
- Fix the error in handling the return value of `getaddrinfo`.
`getaddrinfo` will return an `(int, bytes)` tuple, if CPython could not handle the address family.
It will cause an index out of range error in aiohttp. For example, if user compile CPython with
`--disable-ipv6` option, but his system enable the ipv6.
`5901 <https://github.com/aio-libs/aiohttp/issues/5901>`_
- Do not install "examples" as a top-level package.

### 3.8.0
```
==================
Features
--------
- Added a ``GunicornWebWorker`` feature for extending the aiohttp server configuration by allowing the 'wsgi' coroutine to return ``web.AppRunner`` object.
`2988 <https://github.com/aio-libs/aiohttp/issues/2988>`_
- Switch from ``http-parser`` to ``llhttp``
`3561 <https://github.com/aio-libs/aiohttp/issues/3561>`_
- Use Brotli instead of brotlipy
`3803 <https://github.com/aio-libs/aiohttp/issues/3803>`_
- Disable implicit switch-back to pure python mode. The build fails loudly if aiohttp
cannot be compiled with C Accelerators. Use AIOHTTP_NO_EXTENSIONS=1 to explicitly
disable C Extensions complication and switch to Pure-Python mode. Note that Pure-Python
mode is significantly slower than compiled one.
`3828 <https://github.com/aio-libs/aiohttp/issues/3828>`_
- Make access log use local time with timezone
`3853 <https://github.com/aio-libs/aiohttp/issues/3853>`_
- Implemented ``readuntil`` in ``StreamResponse``
`4054 <https://github.com/aio-libs/aiohttp/issues/4054>`_
- FileResponse now supports ETag.
`4594 <https://github.com/aio-libs/aiohttp/issues/4594>`_
- Add a request handler type alias ``aiohttp.typedefs.Handler``.
`4686 <https://github.com/aio-libs/aiohttp/issues/4686>`_
- ``AioHTTPTestCase`` is more async friendly now.
For people who use unittest and are used to use :py:exc:`~unittest.TestCase`
it will be easier to write new test cases like the sync version of the :py:exc:`~unittest.TestCase` class,
without using the decorator `unittest_run_loop`, just `async def test_*`.
The only difference is that for the people using python3.7 and below a new dependency is needed, it is ``asynctestcase``.
`4700 <https://github.com/aio-libs/aiohttp/issues/4700>`_
- Add validation of HTTP header keys and values to prevent header injection.
`4818 <https://github.com/aio-libs/aiohttp/issues/4818>`_
- Add predicate to ``AbstractCookieJar.clear``.
Add ``AbstractCookieJar.clear_domain`` to clean all domain and subdomains cookies only.

- Switch to external frozenlist and aiosignal libraries.
`5293 <https://github.com/aio-libs/aiohttp/issues/5293>`_
- Don't send secure cookies by insecure transports.
By default, the transport is secure if https or wss scheme is used.
Use `CookieJar(treat_as_secure_origin="http://127.0.0.1")` to override the default security checker.
`5571 <https://github.com/aio-libs/aiohttp/issues/5571>`_
- Always create a new event loop in ``aiohttp.web.run_app()``.
This adds better compatibility with ``asyncio.run()`` or if trying to run multiple apps in sequence.
`5572 <https://github.com/aio-libs/aiohttp/issues/5572>`_
- Add ``aiohttp.pytest_plugin.AiohttpClient`` for static typing of pytest plugin.
`5585 <https://github.com/aio-libs/aiohttp/issues/5585>`_
- Added a ``socket_factory`` argument to ``BaseTestServer``.
`5844 <https://github.com/aio-libs/aiohttp/issues/5844>`_

### 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.

```
### 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.

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.

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.

:tags: bug, engine

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.

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.

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.

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.

: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.

Fixed typing issue with :meth:`_sql.Existing.select_from` that
prevented its use with ORM classes.

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()``.

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.

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__`

It will cause an index out of range error in aiohttp. For example, if user compile CPython with `--disable-ipv6` option, but his system enable the ipv6. `5901 <https://github.com/aio-libs/aiohttp/issues/5901>`_ - Do not install "examples" as a top-level package. `6189 <https://github.com/aio-libs/aiohttp/issues/6189>`_ - Restored ability to connect IPv6-only host. `6195 <https://github.com/aio-libs/aiohttp/issues/6195>`_ - Remove ``Signal`` from ``__all__``, replace ``aiohttp.Signal`` with ``aiosignal.Signal`` in docs `6201 <https://github.com/aio-libs/aiohttp/issues/6201>`_ - Made chunked encoding HTTP header check stricter. `6305 <https://github.com/aio-libs/aiohttp/issues/6305>`_ Improved Documentation ---------------------- - update quick starter demo codes. `6240 <https://github.com/aio-libs/aiohttp/issues/6240>`_ - Added an explanation of how tiny timeouts affect performance to the client reference document. `6274 <https://github.com/aio-libs/aiohttp/issues/6274>`_ - Add flake8-docstrings to flake8 configuration, enable subset of checks. `6276 <https://github.com/aio-libs/aiohttp/issues/6276>`_ - Added information on running complex applications with additional tasks/processes -- :user:`Dreamsorcerer`. `6278 <https://github.com/aio-libs/aiohttp/issues/6278>`_ Misc ---- - `6205 <https://github.com/aio-libs/aiohttp/issues/6205>`_ ---- ``` ### 3.8.0 ``` ================== Features -------- - Added a ``GunicornWebWorker`` feature for extending the aiohttp server configuration by allowing the 'wsgi' coroutine to return ``web.AppRunner`` object. `2988 <https://github.com/aio-libs/aiohttp/issues/2988>`_ - Switch from ``http-parser`` to ``llhttp`` `3561 <https://github.com/aio-libs/aiohttp/issues/3561>`_ - Use Brotli instead of brotlipy `3803 <https://github.com/aio-libs/aiohttp/issues/3803>`_ - Disable implicit switch-back to pure python mode. The build fails loudly if aiohttp cannot be compiled with C Accelerators. Use AIOHTTP_NO_EXTENSIONS=1 to explicitly disable C Extensions complication and switch to Pure-Python mode.

For people who use unittest and are used to use :py:exc:`~unittest.TestCase` it will be easier to write new test cases like the sync version of the :py:exc:`~unittest.TestCase` class, without using the decorator `unittest_run_loop`, just `async def test_*`. The only difference is that for the people using python3.7 and below a new dependency is needed, it is ``asynctestcase``. `4700 <https://github.com/aio-libs/aiohttp/issues/4700>`_ - Add validation of HTTP header keys and values to prevent header injection. `4818 <https://github.com/aio-libs/aiohttp/issues/4818>`_ - Add predicate to ``AbstractCookieJar.clear``.

By default, the transport is secure if https or wss scheme is used. Use `CookieJar(treat_as_secure_origin="http://127.0.0.1")` to override the default security checker. `5571 <https://github.com/aio-libs/aiohttp/issues/5571>`_ - Always create a new event loop in ``aiohttp.web.run_app()``. This adds better compatibility with ``asyncio.run()`` or if trying to run multiple apps in sequence. `5572 <https://github.com/aio-libs/aiohttp/issues/5572>`_ - Add ``aiohttp.pytest_plugin.AiohttpClient`` for static typing of pytest plugin. `5585 <https://github.com/aio-libs/aiohttp/issues/5585>`_ - Added a ``socket_factory`` argument to ``BaseTestServer``. `5844 <https://github.com/aio-libs/aiohttp/issues/5844>`_ - Add compression strategy parameter to enable_compression method. `5909 <https://github.com/aio-libs/aiohttp/issues/5909>`_ - Added support for Python 3.10 to Github Actions CI/CD workflows and fix the related deprecation warnings -- :user:`Hanaasagi`. `5927 <https://github.com/aio-libs/aiohttp/issues/5927>`_ - Switched ``chardet`` to ``charset-normalizer`` for guessing the HTTP payload body encoding -- :user:`Ousret`. `5930 <https://github.com/aio-libs/aiohttp/issues/5930>`_ - Added optional auto_decompress argument for HttpRequestParser `5957 <https://github.com/aio-libs/aiohttp/issues/5957>`_ - Added support for HTTPS proxies to the extent CPython's :py:mod:`asyncio` supports it -- by :user:`bmbouter`, :user:`jborean93` and :user:`webknjaz`. `5992 <https://github.com/aio-libs/aiohttp/issues/5992>`_ - Added ``base_url`` parameter to the initializer of :class:`~aiohttp.ClientSession`. `6013 <https://github.com/aio-libs/aiohttp/issues/6013>`_ - Add Trove classifier and create binary wheels for 3.10. -- :user:`hugovk`. `6079 <https://github.com/aio-libs/aiohttp/issues/6079>`_ - Started shipping platform-specific wheels with the ``musl`` tag targeting typical Alpine Linux runtimes — :user:`asvetlov`. `6139 <https://github.com/aio-libs/aiohttp/issues/6139>`_ - Started shipping platform-specific arm64 wheels for Apple Silicon — :user:`asvetlov`. `6139 <https://github.com/aio-libs/aiohttp/issues/6139>`_ Bugfixes -------- - Modify _drain_helper() to handle concurrent `await resp.write(...)` or `ws.send_json(...)` calls without race-condition. `2934 <https://github.com/aio-libs/aiohttp/issues/2934>`_ - Started using `MultiLoopChildWatcher` when it's available under POSIX while setting up the test I/O loop. `3450 <https://github.com/aio-libs/aiohttp/issues/3450>`_ - Only encode content-disposition filename parameter using percent-encoding.

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` metho
