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




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

- Improved performance of the WebSocket reader -- by :user:`bdraco`.


  *Related issues and pull requests on GitHub:*
  :issue:`8736`, :issue:`8747`.




----


3.10.4 (2024-08-17)
===================

Bug fixes
---------

- 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 (2024-08-10)
========================

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:*
  :issue:`8667`.




----


3.10.2 (2024-08-08)
===================

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 (2024-08-03)
========================

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 (2024-07-30)
========================

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.

  -- by :user:`setla`, :user:`AraHaan`, and :user:`bdraco`


  *Related issues and pull requests on GitHub:*
  :issue:`2507`, :issue:`3315`, :issue:`6722`, :issue:`8481`, :issue:`8482`.



- 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)


  *Related issues and pull requests on GitHub:*
  :issue:`7583`, :issue:`8535`.



- Separated connection and socket timeout errors, from ServerTimeoutError.


  *Related issues and pull requests on GitHub:*
  :issue:`7801`.



- Implemented happy eyeballs


  *Related issues and pull requests on GitHub:*
  :issue:`7954`.



- Added server capability to check for static files with Brotli compression via a ``.br`` extension -- by :user:`steverep`.


  *Related issues and pull requests on GitHub:*
  :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'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: \
  https://docs.aiohttp.org/en/stable/web_advanced.html#graceful-shutdown \
  https://docs.aiohttp.org/en/stable/web_advanced.html#web-handler-cancellation

  -- by :user:`Dreamsorcerer`

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

- Enabled HTTP parser tests originally intended for 3.9.2 release -- by :user:`pajod`.


  *Related issues and pull requests on GitHub:*
  :issue:`8088`.




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

- Improved URL handler resolution time by indexing resources in the UrlDispatcher.
  For applications with a large number of handlers, this should increase performance significantly.
  -- by :user:`bdraco`


  *Related issues and pull requests on GitHub:*
  :issue:`7829`.



- Added `nacl_middleware <https://github.com/CosmicDNA/nacl_middleware>`_ to the list of middlewares in the third party section of the documentation.


  *Related issues and pull requests on GitHub:*
  :issue:`8346`.



- Minor improvements to static typing -- by :user:`Dreamsorcerer`.


  *Related issues and pull requests on GitHub:*
  :issue:`8364`.



- Added a 3.11-specific overloads to ``ClientSession``  -- by :user:`max-muoto`.


  *Related issues and pull requests on GitHub:*
  :issue:`8463`.



- Simplified path checks for ``UrlDispatcher.add_static()`` method -- by :user:`steverep`.


  *Related issues and pull requests on GitHub:*
  :issue:`8491`.



- Avoided creating a future on every websocket receive -- by :user:`bdraco`.


  *Related issues and pull requests on GitHub:*
  :issue:`8498`.



- Updated identity checks for all ``WSMsgType`` type compares -- by :user:`bdraco`.


  *Related issues and pull requests on GitHub:*
  :issue:`8501`.



- When using Python 3.12 or later, the writer is no longer scheduled on the event loop if it can finish synchronously. Avoiding event loop scheduling reduces latency and improves performance. -- by :user:`bdraco`.


  *Related issues and pull requests on GitHub:*
  :issue:`8510`.



- Restored :py:class:`~aiohttp.resolver.AsyncResolver` to be the default resolver. -- by :user:`bdraco`.

  :py:class:`~aiohttp.resolver.AsyncResolver` was disabled by default because
  of IPv6 compatibility issues. These issues have been resolved and
  :py:class:`~aiohttp.resolver.AsyncResolver` is again now the default resolver.


  *Related issues and pull requests on GitHub:*
  :issue:`8522`.




----


3.9.5 (2024-04-16)
==================

Bug fixes
---------

- Fixed "Unclosed client session" when initialization of
  :py:class:`~aiohttp.ClientSession` fails -- by :user:`NewGlad`.


  *Related issues and pull requests on GitHub:*
  :issue:`8253`.



- Fixed regression (from :pr:`8280`) with adding ``Content-Disposition`` to the ``form-data``
  part after appending to writer -- by :user:`Dreamsorcerer`/:user:`Olegt0rr`.


  *Related issues and pull requests on GitHub:*
  :issue:`8332`.



- Added default ``Content-Disposition`` in ``multipart/form-data`` responses to avoid broken
  form-data responses -- by :user:`Dreamsorcerer`.


  *Related issues and pull requests on GitHub:*
  :issue:`8335`.




----


3.9.4 (2024-04-11)
==================

---------

- The asynchronous internals now set the underlying causes
  when assigning exceptions to the future objects
  -- by :user:`webknjaz`.


  *Related issues and pull requests on GitHub:*
  :issue:`8089`.

  for gzip files -- by :user:`steverep`.


  *Related issues and pull requests on GitHub:*
  :issue:`8104`.



- Improved the DNS resolution performance on cache hit -- by :user:`bdraco`.

  This is achieved by avoiding an :mod:`asyncio` task creation in this case.


  *Related issues and pull requests on GitHub:*
  :issue:`8163`.


- Changed the type annotations to allow ``dict`` on :meth:`aiohttp.MultipartWriter.append`,
  :meth:`aiohttp.MultipartWriter.append_json` and
  :meth:`aiohttp.MultipartWriter.append_form` -- by :user:`cakemanny`


  *Related issues and pull requests on GitHub:*
  :issue:`7741`.



- Ensure websocket transport is closed when client does not close it
  -- by :user:`bdraco`.

  The transport could remain open if the client did not close it. This
  change ensures the transport is closed when the client does not close
  it.


  *Related issues and pull requests on GitHub:*
  :issue:`8200`.



- Leave websocket transport open if receive times out or is cancelled
  -- by :user:`bdraco`.

  This restores the behavior prior to the change in #7978.

  answer a question about the long-term maintenance challenges
  they envision as a result of merging their patches
  -- by :user:`webknjaz`.


  *Related issues and pull requests on GitHub:*
  :issue:`8099`.



- Updated CI and documentation to use NPM clean install and upgrade
  node to version 18 -- by :user:`steverep`.


  *Related issues and pull requests on GitHub:*
  :issue:`8116`.



- A pytest fixture ``hello_txt`` was introduced to aid
  static file serving tests in
  :file:`test_web_sendfile_functional.py`. It dynamically
  provisions ``hello.txt`` file variants shared across the
  tests in the module.

  -- by :user:`steverep`


  *Related issues and pull requests on GitHub:*
  :issue:`8136`.




Packaging updates and notes for downstreams
-------------------------------------------

- Added an ``internal`` pytest marker for tests which should be skipped
  by packagers (use ``-m 'not internal'`` to disable them) -- by :user:`Dreamsorcerer`.


  *Related issues and pull requests on GitHub:*
  :issue:`8299`.




----


3.9.3 (2024-01-29)
==================

Bug fixes
---------

- Added runtime type check for ``ClientSession`` ``timeout`` parameter.


  *Related issues and pull requests on GitHub:*
  :issue:`8021`.



- Fixed an unhandled exception in the Python HTTP parser on header lines starting with a colon -- by :user:`pajod`.

  Invalid request lines with anything but a dot between the HTTP major and minor version are now rejected.
  Invalid header field names containing question mark or slash are now rejected.
  Such requests are incompatible with :rfc:`9110#section-5.6.2` and are not known to be of any legitimate use.

   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

Misc
----

- `#6205 <https://github.com/aio-libs/aiohttp/issues/6205>`_


----


3.8.0 (2021-10-31)
==================

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``

  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.

- ``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``.

- Fix interpretation difference of the pure-Python and the Cython-based
  HTTP parsers construct a ``yarl.URL`` object for HTTP request-target.

  Before this fix, the Python parser would turn the URI's absolute-path
  for ``//some-path`` into ``/`` while the Cython code preserved it as
  ``//some-path``. Now, both do the latter.

----


3.1.0 (2018-03-21)
==================

Welcome to aiohttp 3.1 release.

This is an *incremental* release, fully backward compatible with *aiohttp 3.0*.

But we have added several new features.

The most visible one is ``app.add_routes()`` (an alias for existing
``app.router.add_routes()``. The addition is very important because
all *aiohttp* docs now uses ``app.add_routes()`` call in code
snippets. All your existing code still do register routes / resource
without any warning but you've got the idea for a favorite way: noisy
``app.router.add_get()`` is replaced by ``app.add_routes()``.

The library does not make a preference between decorators::

   routes = web.RouteTableDef()

   @routes.get('/')
   async def hello(request):
       return web.Response(text="Hello, world")

   app.add_routes(routes)

and route tables as a list::

   async def hello(request):
       return web.Response(text="Hello, world")

   app.add_routes([web.get('/', hello)])

Both ways are equal, user may decide basing on own code taste.

Also we have a lot of minor features, bug fixes and documentation
updates, see below.

Features
--------

- Relax JSON content-type checking in the ``ClientResponse.json()`` to allow
  "application/xxx+json" instead of strict "application/json". (`#2206 <https://github.com/aio-libs/aiohttp/pull/2206>`_)
- Bump C HTTP parser to version 2.8 (`#2730 <https://github.com/aio-libs/aiohttp/pull/2730>`_)
- Accept a coroutine as an application factory in ``web.run_app`` and gunicorn
  worker. (`#2739 <https://github.com/aio-libs/aiohttp/pull/2739>`_)
- Implement application cleanup context (``app.cleanup_ctx`` property). (`#2747 <https://github.com/aio-libs/aiohttp/pull/2747>`_)
- Make ``writer.write_headers`` a coroutine. (`#2762 <https://github.com/aio-libs/aiohttp/pull/2762>`_)
- Add tracking signals for getting request/response bodies. (`#2767 <https://github.com/aio-libs/aiohttp/pull/2767>`_)

- Install a test event loop as default by ``asyncio.set_event_loop()``. The
  change affects aiohttp test utils but backward compatibility is not broken
  for 99.99% of use cases. (`#2804 <https://github.com/aio-libs/aiohttp/pull/2804>`_)

  arguments mandatory, drop ``_post_init()`` method. (`#2820 <https://github.com/aio-libs/aiohttp/pull/2820>`_)
- Use ``app.add_routes()`` in server docs everywhere (`#2830 <https://github.com/aio-libs/aiohttp/pull/2830>`_)

  ``range.start`` rather then in ``range.stop`` (`#2805 <https://github.com/aio-libs/aiohttp/pull/2805>`_)
- Close a connection if an unexpected exception occurs while sending a request
  (`#2827 <https://github.com/aio-libs/aiohttp/pull/2827>`_)
