Update aiohttp to 3.10.10

[pyup-bot]

This PR updates aiohttp from 3.9.1 to 3.10.10.

Changelog

3.10.9

===================

Bug fixes
---------

- Fixed proxy headers being used in the ``ConnectionKey`` hash when a proxy was not being used -- by :user:`bdraco`.

If default headers are used, they are also used for proxy headers. This could have led to creating connections that were not needed when one was already available.


*Related issues and pull requests on GitHub:*
:issue:`9368`.



- Widened the type of the ``trace_request_ctx`` parameter of
:meth:`ClientSession.request() <aiohttp.ClientSession.request>` and friends
-- by :user:`layday`.


*Related issues and pull requests on GitHub:*
:issue:`9397`.




Removals and backward incompatible breaking changes
---------------------------------------------------

- Fixed failure to try next host after single-host connection timeout -- by :user:`brettdh`.

The default client :class:`aiohttp.ClientTimeout` params has changed to include a ``sock_connect`` timeout of 30 seconds so that this correct behavior happens by default.


*Related issues and pull requests on GitHub:*
:issue:`7342`.




Miscellaneous internal changes
------------------------------

- Improved performance of resolving hosts with Python 3.12+ -- by :user:`bdraco`.

*Related issues and pull requests on GitHub:*
:issue:`9309`.




Miscellaneous internal changes
------------------------------

- Improved performance of determining if a URL is absolute -- by :user:`bdraco`.

The property :attr:`~yarl.URL.absolute` is more performant than the method ``URL.is_absolute()`` and preferred when newer versions of yarl are used.


*Related issues and pull requests on GitHub:*

*Related issues and pull requests on GitHub:*
:issue:`8748`.




Removals and backward incompatible breaking changes
---------------------------------------------------

- Improved middleware performance -- by :user:`bdraco`.

The ``set_current_app`` method was removed from ``UrlMappingMatchInfo`` because it is no longer used, and it was unlikely external caller would ever use it.


*Related issues and pull requests on GitHub:*
:issue:`9200`.

*Related issues and pull requests on GitHub:*
:issue:`4414`.



- Clarified that auth parameter in ClientSession will persist and be included with any request to any origin, even during redirects to different origins.  -- by :user:`MaximZemskov`.


*Related issues and pull requests on GitHub:*

If yarl is older than 1.11.0, the previous slower hand rolled version will be used.


*Related issues and pull requests on GitHub:*
:issue:`9068`.



- Improved performance of checking if a host is an IP Address -- by :user:`bdraco`.


*Related issues and pull requests on GitHub:*
:issue:`9095`.



- Significantly improved performance of middlewares -- by :user:`bdraco`.

The construction of the middleware wrappers is now cached and is built once per handler instead of on every request.

---------

- Fixed :meth:`aiohttp.ClientResponse.json()` not setting ``status`` when :exc:`aiohttp.ContentTypeError` is raised -- by :user:`bdraco`.


*Related issues and pull requests on GitHub:*
:issue:`8742`.




Miscellaneous internal changes

---------

- Fixed decoding base64 chunk in BodyPartReader -- by :user:`hyzyla`.


*Related issues and pull requests on GitHub:*
:issue:`3867`.



- Fixed a race closing the server-side WebSocket where the close code would not reach the client -- by :user:`bdraco`.


*Related issues and pull requests on GitHub:*
:issue:`8680`.



- Fixed unconsumed exceptions raised by the WebSocket heartbeat -- by :user:`bdraco`.

If the heartbeat ping raised an exception, it would not be consumed and would be logged as an warning.


*Related issues and pull requests on GitHub:*
:issue:`8685`.



- Fixed an edge case in the Python parser when chunk separators happen to align with network chunks -- by :user:`Dreamsorcerer`.


*Related issues and pull requests on GitHub:*
:issue:`8720`.




Improved documentation
----------------------

- Added ``aiohttp-apischema`` to supported libraries -- by :user:`Dreamsorcerer`.


*Related issues and pull requests on GitHub:*
:issue:`8700`.




Miscellaneous internal changes
------------------------------

- Improved performance of starting request handlers with Python 3.12+ -- by :user:`bdraco`.

This change is a followup to :issue:`8661` to make the same optimization for Python 3.12+ where the request is connected.


*Related issues and pull requests on GitHub:*
:issue:`8681`.




----

3.10.3

========================

Bug fixes
---------

- Fixed multipart reading when stream buffer splits the boundary over several read() calls -- by :user:`Dreamsorcerer`.


*Related issues and pull requests on GitHub:*
:issue:`8653`.



- Fixed :py:class:`aiohttp.TCPConnector` doing blocking I/O in the event loop to create the ``SSLContext`` -- by :user:`bdraco`.

The blocking I/O would only happen once per verify mode. However, it could cause the event loop to block for a long time if the ``SSLContext`` creation is slow, which is more likely during startup when the disk cache is not yet present.


*Related issues and pull requests on GitHub:*
:issue:`8672`.




Miscellaneous internal changes
------------------------------

- Improved performance of :py:meth:`~aiohttp.ClientWebSocketResponse.receive` and :py:meth:`~aiohttp.web.WebSocketResponse.receive` when there is no timeout. -- by :user:`bdraco`.

The timeout context manager is now avoided when there is no timeout as it accounted for up to 50% of the time spent in the :py:meth:`~aiohttp.ClientWebSocketResponse.receive` and :py:meth:`~aiohttp.web.WebSocketResponse.receive` methods.


*Related issues and pull requests on GitHub:*
:issue:`8660`.



- Improved performance of starting request handlers with Python 3.12+ -- by :user:`bdraco`.


*Related issues and pull requests on GitHub:*
:issue:`8661`.



- Improved performance of HTTP keep-alive checks -- by :user:`bdraco`.

Previously, when processing a request for a keep-alive connection, the keep-alive check would happen every second; the check is now rescheduled if it fires too early instead.


*Related issues and pull requests on GitHub:*
:issue:`8662`.



- Improved performance of generating random WebSocket mask -- by :user:`bdraco`.


*Related issues and pull requests on GitHub:*

3.10.2

===================

Bug fixes
---------

- Fixed server checks for circular symbolic links to be compatible with Python 3.13 -- by :user:`steverep`.


*Related issues and pull requests on GitHub:*
:issue:`8565`.



- Fixed request body not being read when ignoring an Upgrade request -- by :user:`Dreamsorcerer`.


*Related issues and pull requests on GitHub:*
:issue:`8597`.



- Fixed an edge case where shutdown would wait for timeout when the handler was already completed -- by :user:`Dreamsorcerer`.


*Related issues and pull requests on GitHub:*
:issue:`8611`.



- Fixed connecting to ``npipe://``, ``tcp://``, and ``unix://`` urls -- by :user:`bdraco`.


*Related issues and pull requests on GitHub:*
:issue:`8632`.



- Fixed WebSocket ping tasks being prematurely garbage collected -- by :user:`bdraco`.

There was a small risk that WebSocket ping tasks would be prematurely garbage collected because the event loop only holds a weak reference to the task. The garbage collection risk has been fixed by holding a strong reference to the task. Additionally, the task is now scheduled eagerly with Python 3.12+ to increase the chance it can be completed immediately and avoid having to hold any references to the task.


*Related issues and pull requests on GitHub:*
:issue:`8641`.



- Fixed incorrectly following symlinks for compressed file variants -- by :user:`steverep`.


*Related issues and pull requests on GitHub:*
:issue:`8652`.




Removals and backward incompatible breaking changes
---------------------------------------------------

- Removed ``Request.wait_for_disconnection()``, which was mistakenly added briefly in 3.10.0 -- by :user:`Dreamsorcerer`.


*Related issues and pull requests on GitHub:*
:issue:`8636`.




Contributor-facing changes
--------------------------

- Fixed monkey patches for ``Path.stat()`` and ``Path.is_dir()`` for Python 3.13 compatibility -- by :user:`steverep`.


*Related issues and pull requests on GitHub:*
:issue:`8551`.




Miscellaneous internal changes
------------------------------

- Improved WebSocket performance when messages are sent or received frequently -- by :user:`bdraco`.

The WebSocket heartbeat scheduling algorithm was improved to reduce the ``asyncio`` scheduling overhead by decreasing the number of ``asyncio.TimerHandle`` creations and cancellations.


*Related issues and pull requests on GitHub:*
:issue:`8608`.



- Minor improvements to various type annotations -- by :user:`Dreamsorcerer`.


*Related issues and pull requests on GitHub:*
:issue:`8634`.




----

3.10.1

========================

Bug fixes
---------

- Fixed WebSocket server heartbeat timeout logic to terminate :py:meth:`~aiohttp.ClientWebSocketResponse.receive` and return :py:class:`~aiohttp.ServerTimeoutError` -- by :user:`arcivanov`.

When a WebSocket pong message was not received, the :py:meth:`~aiohttp.ClientWebSocketResponse.receive` operation did not terminate. This change causes ``_pong_not_received`` to feed the ``reader`` an error message, causing pending :py:meth:`~aiohttp.ClientWebSocketResponse.receive` to terminate and return the error message. The error message contains the exception :py:class:`~aiohttp.ServerTimeoutError`.


*Related issues and pull requests on GitHub:*
:issue:`8540`.



- Fixed url dispatcher index not matching when a variable is preceded by a fixed string after a slash -- by :user:`bdraco`.


*Related issues and pull requests on GitHub:*
:issue:`8566`.




Removals and backward incompatible breaking changes
---------------------------------------------------

- Creating :py:class:`aiohttp.TCPConnector`, :py:class:`aiohttp.ClientSession`, :py:class:`~aiohttp.resolver.ThreadedResolver` :py:class:`aiohttp.web.Server`, or :py:class:`aiohttp.CookieJar` instances without a running event loop now raises a :exc:`RuntimeError` -- by :user:`asvetlov`.

Creating these objects without a running event loop was deprecated in :issue:`3372` which was released in version 3.5.0.

This change first appeared in version 3.10.0 as :issue:`6378`.


*Related issues and pull requests on GitHub:*
:issue:`8555`, :issue:`8583`.




----

3.10.0

========================

Bug fixes
---------

- Fixed server response headers for ``Content-Type`` and ``Content-Encoding`` for
static compressed files -- by :user:`steverep`.

Server will now respond with a ``Content-Type`` appropriate for the compressed
file (e.g. ``"application/gzip"``), and omit the ``Content-Encoding`` header.
Users should expect that most clients will no longer decompress such responses
by default.


*Related issues and pull requests on GitHub:*
:issue:`4462`.



- Fixed duplicate cookie expiration calls in the CookieJar implementation


*Related issues and pull requests on GitHub:*
:issue:`7784`.



- Adjusted ``FileResponse`` to check file existence and access when preparing the response -- by :user:`steverep`.

The :py:class:`~aiohttp.web.FileResponse` class was modified to respond with
403 Forbidden or 404 Not Found as appropriate.  Previously, it would cause a
server error if the path did not exist or could not be accessed.  Checks for
existence, non-regular files, and permissions were expected to be done in the
route handler.  For static routes, this now permits a compressed file to exist
without its uncompressed variant and still be served.  In addition, this
changes the response status for files without read permission to 403, and for
non-regular files from 404 to 403 for consistency.


*Related issues and pull requests on GitHub:*
:issue:`8182`.



- Fixed ``AsyncResolver`` to match ``ThreadedResolver`` behavior
-- by :user:`bdraco`.

On system with IPv6 support, the :py:class:`~aiohttp.resolver.AsyncResolver` would not fallback
to providing A records when AAAA records were not available.
Additionally, unlike the :py:class:`~aiohttp.resolver.ThreadedResolver`, the :py:class:`~aiohttp.resolver.AsyncResolver`
did not handle link-local addresses correctly.

This change makes the behavior consistent with the :py:class:`~aiohttp.resolver.ThreadedResolver`.


*Related issues and pull requests on GitHub:*
:issue:`8270`.



- Fixed ``ws_connect`` not respecting `receive_timeout`` on WS(S) connection.
-- by :user:`arcivanov`.


*Related issues and pull requests on GitHub:*
:issue:`8444`.



- Removed blocking I/O in the event loop for static resources and refactored
exception handling -- by :user:`steverep`.

File system calls when handling requests for static routes were moved to a
separate thread to potentially improve performance. Exception handling
was tightened in order to only return 403 Forbidden or 404 Not Found responses
for expected scenarios; 500 Internal Server Error would be returned for any
unknown errors.


*Related issues and pull requests on GitHub:*
:issue:`8507`.




Features
--------

- Added a Request.wait_for_disconnection() method, as means of allowing request handlers to be notified of premature client disconnections.


*Related issues and pull requests on GitHub:*
:issue:`2492`.



- Added 5 new exceptions: :py:exc:`~aiohttp.InvalidUrlClientError`, :py:exc:`~aiohttp.RedirectClientError`,
:py:exc:`~aiohttp.NonHttpUrlClientError`, :py:exc:`~aiohttp.InvalidUrlRedirectClientError`,
:py:exc:`~aiohttp.NonHttpUrlRedirectClientError`

:py:exc:`~aiohttp.InvalidUrlRedirectClientError`, :py:exc:`~aiohttp.NonHttpUrlRedirectClientError`
are raised instead of :py:exc:`ValueError` or :py:exc:`~aiohttp.InvalidURL` when the redirect URL is invalid. Classes
:py:exc:`~aiohttp.InvalidUrlClientError`, :py:exc:`~aiohttp.RedirectClientError`,
:py:exc:`~aiohttp.NonHttpUrlClientError` are base for them.

The :py:exc:`~aiohttp.InvalidURL` now exposes a ``description`` property with the text explanation of the error details.

- Added a feature to retry closed connections automatically for idempotent methods. -- by :user:`Dreamsorcerer`


*Related issues and pull requests on GitHub:*
:issue:`7297`.



- Implemented filter_cookies() with domain-matching and path-matching on the keys, instead of testing every single cookie.
This may break existing cookies that have been saved with `CookieJar.save()`. Cookies can be migrated with this script::

   import pickle
   with file_path.open("rb") as f:
       cookies = pickle.load(f)

   morsels = [(name, m) for c in cookies.values() for name, m in c.items()]
   cookies.clear()
   for name, m in morsels:
       cookies[(m["domain"], m["path"].rstrip("/"))][name] = m

   with file_path.open("wb") as f:
       pickle.dump(cookies, f, pickle.HIGHEST_PROTOCOL)

Removals and backward incompatible breaking changes
---------------------------------------------------

- The shutdown logic in 3.9 waited on all tasks, which caused issues with some libraries.
In 3.10 we've changed this logic to only wait on request handlers. This means that it's
important for developers to correctly handle the lifecycle of background tasks using a
library such as ``aiojobs``. If an application is using ``handler_cancellation=True`` then
it is also a good idea to ensure that any :func:`asyncio.shield` calls are replaced with
:func:`aiojobs.aiohttp.shield`.

Please read the updated documentation on these points: \
