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

Bug fixes
---------

*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:`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:*

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`.

: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:*

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. ``&quot;application/gzip&quot;``), 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.

*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(&quot;rb&quot;) 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[&quot;domain&quot;], m[&quot;path&quot;].rstrip(&quot;/&quot;))][name] = m

   with file_path.open(&quot;wb&quot;) as f:
       pickle.dump(cookies, f, pickle.HIGHEST_PROTOCOL)

:issue:`8062`.




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&#x27;ve changed this logic to only wait on request handlers. This means that it&#x27;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: \
