3.8.5 (2023-07-19)
==================
Security bugfixes
-----------------
- Upgraded the vendored copy of llhttp_ to v8.1.1 -- by :user:`webknjaz`
and :user:`Dreamsorcerer`.
Thanks to :user:`sethmlarson` for reporting this and providing us with
comprehensive reproducer, workarounds and fixing details! For more
information, see
.. _llhttp: https://llhttp.org
Features
--------
- Added information to C parser exceptions to show which character caused the error. -- by :user:`Dreamsorcerer`
Bugfixes
--------
- Fixed a transport is :data:`None` error -- by :user:`Dreamsorcerer`.
----
3.8.4 (2023-02-12)
==================
Bugfixes
--------
- Fixed incorrectly overwriting cookies with the same name and domain, but different path.
- Fixed ``ConnectionResetError`` not being raised after client disconnection in SSL environments.
----
3.8.3 (2022-09-21)
==================
.. 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``.
----
3.8.2 (2022-09-20, subsequently yanked on 2022-09-21)
=====================================================
.. note::
This release has some compatibility fixes for Python 3.11 but it may
still have some quirks. Some tests are still flaky in the CI.
.. caution::
This release has been yanked from PyPI. Modern pip will not pick it
up automatically. The reason is that is has ``multidict < 6`` set in
the distribution package metadata (see :pr:`6950`). Please, use
``aiohttp ~= 3.8.3, != 3.8.1`` instead, if you can.
Bugfixes
--------
- Added support for registering :rfc:`OPTIONS <9110#OPTIONS>`
HTTP method handlers via :py:class:`~aiohttp.web.RouteTableDef`.
- Started supporting :rfc:`authority-form <9112#authority-form>` and
:rfc:`absolute-form <9112#absolute-form>` URLs on the server-side.
- Fixed Python 3.11 incompatibilities by using Cython 0.29.25.
- Extended the ``sock`` argument typing declaration of the
:py:func:`~aiohttp.web.run_app` function as optionally
accepting iterables.
- Fixed a regression where :py:exc:`~asyncio.CancelledError`
occurs on client disconnection.
- Started exporting :py:class:`~aiohttp.web.PrefixedSubAppResource`
under :py:mod:`aiohttp.web` -- by :user:`Dreamsorcerer`.
This fixes a regression introduced by :pr:`3469`.
- Dropped the :class:`object` type possibility from
the :py:attr:`aiohttp.ClientSession.timeout`
property return type declaration.
Improved Documentation
----------------------
- Added clarification on configuring the app object with
settings such as a database connection.
- Extended the ``sock`` argument typing declaration of the
:py:func:`~aiohttp.web.run_app` function as optionally
accepting iterables.
- Dropped the :class:`object` type possibility from
the :py:attr:`aiohttp.ClientSession.timeout`
property return type declaration.
Deprecations and Removals
-------------------------
- Dropped Python 3.5 support, :doc:`aiohttp <index>` only works
under Python 3.6 and higher from now on.
Misc
----
- Removed a deprecated usage of :py:func:`pytest.warns(None)
<pytest.warns>` in tests.
----
3.8.1 (2021-11-14)
==================
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 a index out of range error in aiohttp. For example, if user compile CPython with
`--disable-ipv6` option but his system enable the ipv6.
- Do not install "examples" as a top-level package.
- Restored ability to connect IPv6-only host.
- Remove ``Signal`` from ``__all__``, replace ``aiohttp.Signal`` with ``aiosignal.Signal`` in docs
- Made chunked encoding HTTP header check stricter.
Improved Documentation
----------------------
- update quick starter demo codes.
- Added an explanation of how tiny timeouts affect performance to the client reference document.
- Add flake8-docstrings to flake8 configuration, enable subset of checks.
- Added information on running complex applications with additional tasks/processes -- :user:`Dreamsorcerer`.
Misc

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.
- Switch from ``http-parser`` to ``llhttp``
- Use Brotli instead of brotlipy
- 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.
- Make access log use local time with timezone
- Implemented ``readuntil`` in ``StreamResponse``
- FileResponse now supports ETag.
- Add a request handler type alias ``aiohttp.typedefs.Handler``.
- ``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``.
- Add validation of HTTP header keys and values to prevent header injection.
- Add predicate to ``AbstractCookieJar.clear``.
Add ``AbstractCookieJar.clear_domain`` to clean all domain and subdomains cookies only.
- Add keepalive_timeout parameter to web.run_app.
- Tracing for client sent headers
- Make type hints for http parser stricter
- Add final declarations for constants.
- Switch to external frozenlist and aiosignal libraries.
- 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.
- 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.
- Add ``aiohttp.pytest_plugin.AiohttpClient`` for static typing of pytest plugin.
- Added a ``socket_factory`` argument to ``BaseTestServer``.
- Add compression strategy parameter to enable_compression method.
- Added support for Python 3.10 to Github Actions CI/CD workflows and fix the related deprecation warnings -- :user:`Hanaasagi`.
- Switched ``chardet`` to ``charset-normalizer`` for guessing the HTTP payload body encoding -- :user:`Ousret`.
- Added optional auto_decompress argument for HttpRequestParser
- Added support for HTTPS proxies to the extent CPython's
:py:mod:`asyncio` supports it -- by :user:`bmbouter`,
:user:`jborean93` and :user:`webknjaz`.
- Added ``base_url`` parameter to the initializer of :class:`~aiohttp.ClientSession`.
- Add Trove classifier and create binary wheels for 3.10. -- :user:`hugovk`.
- Started shipping platform-specific wheels with the ``musl`` tag targeting typical Alpine Linux runtimes — :user:`asvetlov`.
- Started shipping platform-specific arm64 wheels for Apple Silicon — :user:`asvetlov`.
Bugfixes
--------
- Modify _drain_helper() to handle concurrent `await resp.write(...)` or `ws.send_json(...)` calls without race-condition.
- Started using `MultiLoopChildWatcher` when it's available under POSIX while setting up the test I/O loop.
- Only encode content-disposition filename parameter using percent-encoding.
Other parameters are encoded to quoted-string or RFC2231 extended parameter
value.
- Fixed HTTP client requests to honor ``no_proxy`` environment variables.
- Fix supporting WebSockets proxies configured via environment variables.
- Change return type on URLDispatcher to UrlMappingMatchInfo to improve type annotations.
- Ensure a cleanup context is cleaned up even when an exception occurs during startup.
- Added a new exception type for Unix socket client errors which provides a more useful error message.
- Remove Transfer-Encoding and Content-Type headers for 204 in StreamResponse
- Only depend on typing_extensions for Python <3.8
- Add ABNORMAL_CLOSURE and BAD_GATEWAY to WSCloseCode
- Fix cookies disappearing from HTTPExceptions.
- StaticResource prefixes no longer match URLs with a non-folder prefix. For example ``routes.static('/foo', '/foo')`` no longer matches the URL ``/foobar``. Previously, this would attempt to load the file ``/foo/ar``.
- Acquire the connection before running traces to prevent race condition.
- Add missing slots to ```_RequestContextManager`` and ``_WSRequestContextManager``
- Ensure sending a zero byte file does not throw an exception (round 2)
- Set "text/plain" when data is an empty string in client requests.
- Stop automatically releasing the ``ClientResponse`` object on calls to the ``ok`` property for the failed requests.
- Include query parameters from `params` keyword argument in tracing `URL`.
- Fix annotations
- Fixed the multipart POST requests processing to always release file
descriptors for the ``tempfile.Temporaryfile``-created
``_io.BufferedRandom`` instances of files sent within multipart request
bodies via HTTP POST requests -- by :user:`webknjaz`.
- Fix 0 being incorrectly treated as an immediate timeout.
- Fixes failing tests when an environment variable <scheme>_proxy is set.
- Replace deprecated app handler design in ``tests/autobahn/server.py`` with call to ``web.run_app``; replace deprecated ``aiohttp.ws_connect`` calls in ``tests/autobahn/client.py`` with ``aiohttp.ClienSession.ws_connect``.
- Fixed test for ``HTTPUnauthorized`` that access the ``text`` argument. This is not used in any part of the code, so it's removed now.
- Remove incorrect default from docs
- Remove external test dependency to http://httpbin.org
- Don't cancel current task when entering a cancelled timer.
- Added ``params`` keyword argument to ``ClientSession.ws_connect``. -- :user:`hoh`.
- Uses :py:class:`~asyncio.ThreadedChildWatcher` under POSIX to allow setting up test loop in non-main thread.
- 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 a index out of range error in aiohttp. For example, if user compile CPython with
`--disable-ipv6` option but his system enable the ipv6.
- Removed the deprecated ``loop`` argument from the ``asyncio.sleep``/``gather`` calls
- Return ``None`` from ``request.if_modified_since``, ``request.if_unmodified_since``, ``request.if_range`` and ``response.last_modified`` when corresponding http date headers are invalid.
- Fix resetting `SIGCHLD` signals in Gunicorn aiohttp Worker to fix `subprocesses` that capture output having an incorrect `returncode`.
- Raise ``400: Content-Length can't be present with Transfer-Encoding`` if both ``Content-Length`` and ``Transfer-Encoding`` are sent by peer by both C and Python implementations
Improved Documentation
----------------------
- Refactored OpenAPI/Swagger aiohttp addons, added ``aio-openapi``
- Fixed docs on request cookies type, so it matches what is actually used in the code (a
read-only dictionary-like object).
- Documented that the HTTP client ``Authorization`` header is removed
on redirects to a different host or protocol.

3.7.4.post0 (2021-03-06)
========================
Misc
----
- Bumped upper bound of the ``chardet`` runtime dependency
to allow their v4.0 version stream.
----
3.7.4 (2021-02-25)
==================
Bugfixes
--------
- **(SECURITY BUG)** Started preventing open redirects in the
``aiohttp.web.normalize_path_middleware`` middleware. For
more details, see
Thanks to `Beast Glatisant <https://github.com/g147>`__ for
finding the first instance of this issue and `Jelmer Vernooij
<https://jelmer.uk/>`__ for reporting and tracking it down
in aiohttp.
- 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.
----

----
3.7.1 (2020-10-25)
==================
Bugfixes
--------
- Fixed a type error caused by the conditional import of `Protocol`.
- Server doesn't send Content-Length for 1xx or 204
- Fix run_app typing
- Always require ``typing_extensions`` library.
- Fix a variable-shadowing bug causing `ThreadedResolver.resolve` to
return the resolved IP as the ``hostname`` in each record, which prevented

----
3.7.0 (2020-10-24)
==================
Features
--------
- Response headers are now prepared prior to running ``on_response_prepare`` hooks, directly before headers are sent to the client.
- Add a ``quote_cookie`` option to ``CookieJar``, a way to skip quotation wrapping of cookies containing special characters.
- Call ``AccessLogger.log`` with the current exception available from ``sys.exc_info()``.
- `web.UrlDispatcher.add_routes` and `web.Application.add_routes` return a list
of registered `AbstractRoute` instances. `AbstractRouteDef.register` (and all
subclasses) return a list of registered resources registered resource.
- Added properties of default ClientSession params to ClientSession class so it is available for introspection
- Don't cancel web handler on peer disconnection, raise `OSError` on reading/writing instead.
- Implement BaseRequest.get_extra_info() to access a protocol transports' extra info.
- Added `ClientSession.timeout` property.
- allow use of SameSite in cookies.
- Use ``loop.sendfile()`` instead of custom implementation if available.
- Apply SO_REUSEADDR to test server's socket.
- Use .raw_host instead of slower .host in client API
- Allow configuring the buffer size of input stream by passing ``read_bufsize`` argument.
- Pass tests on Python 3.8 for Windows.

- Add ClientResponse.ok property for checking status code under 400.
- Don't ceil timeouts that are smaller than 5 seconds.
- TCPSite now listens by default on all interfaces instead of just IPv4 when `None` is passed in as the host.
- Bump ``http_parser`` to 2.9.4
Bugfixes
--------
- Fix keepalive connections not being closed in time
- Fix failed websocket handshake leaving connection hanging.
- Fix tasks cancellation order on exit. The run_app task needs to be cancelled first for cleanup hooks to run with all tasks intact.
- Don't start heartbeat until _writer is set
- Fix handling of multipart file uploads without a content type.
- Preserve view handler function attributes across middlewares
- Fix the string representation of ``ServerDisconnectedError``.
- Raising RuntimeError when trying to get encoding from not read body
- Remove warning messages from noop.
- Raise ClientPayloadError if FormData re-processed.
- Fix a warning about unfinished task in ``web_protocol.py``
- Fixed 'deflate' compression. According to RFC 2616 now.

- Fixed request.body_exists returns wrong value for methods without body.
- Fix connecting to link-local IPv6 addresses.
- Fix a problem with connection waiters that are never awaited.
- Always make sure transport is not closing before reuse a connection.
Reuse a protocol based on keepalive in headers is unreliable.
For example, uWSGI will not support keepalive even it serves a
HTTP 1.1 request, except explicitly configure uWSGI with a
``--http-keepalive`` option.
Servers designed like uWSGI could cause aiohttp intermittently
raise a ConnectionResetException when the protocol poll runs
out and some protocol is reused.
- Handle the last CRLF correctly even if it is received via separate TCP segment.

- Add HTTPMove to _all__.
- Fixed the type annotations in the ``tracing`` module.
- Fix typing for multipart ``__aiter__``.
- Fix for race condition on connections in BaseConnector that leads to exceeding the connection limit.
- Add forced UTF-8 encoding for ``application/rdap+json`` responses.
- Fix inconsistency between Python and C http request parsers in parsing pct-encoded URL.
- Fix connection closing issue in HEAD request.
- Fix type hint on BaseRunner.addresses (from ``List[str]`` to ``List[Any]``)
- Make `web.run_app()` more responsive to Ctrl+C on Windows for Python < 3.8. It slightly
increases CPU load as a side effect.
Improved Documentation
----------------------

Improved Documentation
----------------------
- Added minimal required logging configuration to logging documentation.
- Update docs to reflect proxy support.
- Fix typo in code example in testing docs.

----
3.6.0 (2019-09-06)
==================
Features
--------

Bugfixes
--------
- Raise a ClientResponseError instead of an AssertionError for a blank
HTTP Reason Phrase.
- Fix an issue where cookies would sometimes not be set during a redirect.

This behavior should prevent clients from being unable to use PUT/POST
methods on endpoints that are redirected because of a trailing slash.
- Drop the processed task from ``all_tasks()`` list early. It prevents logging about a
task with unhandled exception when the server is used in conjunction with
``asyncio.run()``. `#3587 <https://github.com/aio-libs/aiohttp/issues/3587>`_
- ``Signal`` type annotation changed from ``Signal[Callable[['TraceConfig'],
Awaitable[None]]]`` to ``Signal[Callable[ClientSession, SimpleNamespace, ...]``.

- Send custom per-request cookies even if session jar is empty
- Restore Linux binary wheels publishing on PyPI
----
3.5.2 (2019-01-08)
==================
Features
--------
- ``FileResponse`` from ``web_fileresponse.py`` uses a ``ThreadPoolExecutor`` to work
with files asynchronously. I/O based payloads from ``payload.py`` uses a
``ThreadPoolExecutor`` to work with I/O objects asynchronously. `#3313
- Internal Server Errors in plain text if the browser does not support HTML.
Bugfixes
--------
- Preserve MultipartWriter parts headers on write. Refactor the way how
``Payload.headers`` are handled. Payload instances now always have headers and
Content-Type defined. Fix Payload Content-Disposition header reset after initial
- Log suppressed exceptions in ``GunicornWebWorker``.
- Remove wildcard imports.
- Use the same task for app initialization and web server handling in gunicorn workers.
It allows to use Python3.7 context vars smoothly.
- Fix handling of chunked+gzipped response when first chunk does not give uncompressed
- Replace ``collections.MutableMapping`` with ``collections.abc.MutableMapping`` to
avoid a deprecation warning. `#3480

3.5.1 (2018-12-24)
====================
- Fix a regression about ``ClientSession._requote_redirect_url`` modification in debug
mode.
3.5.0 (2018-12-22)
====================
Features
--------
- The library type annotations are checked in strict mode now.
- Add support for setting cookies for individual request (`#2387
- Application.add_domain implementation (`#2809
- The default ``app`` in the request returned by ``test_utils.make_mocked_request`` can
now have objects assigned to it and retrieved using the ``[]`` operator. (`#3174
- Make ``request.url`` accessible when transport is closed. (`#3177
- Add ``zlib_executor_size`` argument to ``Response`` constructor to allow compression
to run in a background executor to avoid blocking the main thread and potentially
triggering health check failures. (`#3205
- Enable users to set ``ClientTimeout`` in ``aiohttp.request`` (`#3213
- Don't raise a warning if ``NETRC`` environment variable is not set and ``~/.netrc``
file doesn't exist. (`#3267 <https://github.com/aio-libs/aiohttp/pull/3267>`_)
- Add default logging handler to web.run_app If the ``Application.debug``` flag is set
and the default logger ``aiohttp.access`` is used, access logs will now be output
using a *stderr* ``StreamHandler`` if no handlers are attached. Furthermore, if the
default logger has no log level set, the log level will be set to ``DEBUG``. (`#3324
- Add method argument to ``session.ws_connect()``. Sometimes server API requires a
different HTTP method for WebSocket connection establishment. For example, ``Docker
exec`` needs POST. (`#3378 <https://github.com/aio-libs/aiohttp/pull/3378>`_)
- Create a task per request handling. (`#3406
Bugfixes
--------
- Enable passing ``access_log_class`` via ``handler_args`` (`#3158
