v3.12.13

Compare Source

v3.12.12

Compare Source

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

Bug fixes

  • Fixed cookie unquoting to properly handle octal escape sequences in cookie values (e.g., \012 for newline) by vendoring the correct _unquote implementation from Python's http.cookies module -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:11173.

  • Fixed Cookie header parsing to treat attribute names as regular cookies per :rfc:6265#section-5.4 -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:11178.


v3.12.11

Compare Source

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

Features

  • Improved SSL connection handling by changing the default ssl_shutdown_timeout
    from 0.1 to 0 seconds. SSL connections now use Python's default graceful
    shutdown during normal operation but are aborted immediately when the connector
    is closed, providing optimal behavior for both cases. Also added support for
    ssl_shutdown_timeout=0 on all Python versions. Previously, this value was
    rejected on Python 3.11+ and ignored on earlier versions. Non-zero values on
    Python < 3.11 now trigger a RuntimeWarning -- by :user:bdraco.

    The ssl_shutdown_timeout parameter is now deprecated and will be removed in
    aiohttp 4.0 as there is no clear use case for changing the default.

    :issue:11148.

Deprecations (removal in next major release)

    from 0.1 to 0 seconds. SSL connections now use Python's default graceful
    shutdown during normal operation but are aborted immediately when the connector
    is closed, providing optimal behavior for both cases. Also added support for
    ssl_shutdown_timeout=0 on all Python versions. Previously, this value was

v3.12.10

Compare Source

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

Bug fixes

  • Fixed leak of aiodns.DNSResolver when :py:class:~aiohttp.TCPConnector is closed and no resolver was passed when creating the connector -- by :user:Tasssadar.

    This was a regression introduced in version 3.12.0 (:pr:10897).

    Related issues and pull requests on GitHub:
    :issue:11150.


v3.12.9

Compare Source

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

Bug fixes

  • Fixed IOBasePayload and TextIOPayload reading entire files into memory when streaming large files -- by :user:bdraco.

    When using file-like objects with the aiohttp client, the entire file would be read into memory if the file size was provided in the Content-Length header. This could cause out-of-memory errors when uploading large files. The payload classes now correctly read data in chunks of READ_SIZE (64KB) regardless of the total content length.

    Related issues and pull requests on GitHub:
    :issue:11138.


v3.12.8

Compare Source

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

Features

  • Added preemptive digest authentication to :class:~aiohttp.DigestAuthMiddleware -- by :user:bdraco.

    The middleware now reuses authentication credentials for subsequent requests to the same
    protection space, improving efficiency by avoiding extra authentication round trips.
    This behavior matches how web browsers handle digest authentication and follows
    :rfc:7616#section-3.6.

    Preemptive authentication is enabled by default but can be disabled by passing
    preemptive=False to the middleware constructor.

    Related issues and pull requests on GitHub:
    :issue:11128, :issue:11129.


v3.12.7

Compare Source

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

Bug fixes

  • Fixed cookie parsing to be more lenient when handling cookies with special characters
    in names or values. Cookies with characters like {, }, and / in names are now
    accepted instead of causing a :exc:~http.cookies.CookieError and 500 errors. Additionally,
    cookies with mismatched quotes in values are now parsed correctly, and quoted cookie
    values are now handled consistently whether or not they include special attributes
    like Domain. Also fixed :class:~aiohttp.CookieJar to ensure shared cookies (domain="", path="")
    respect the quote_cookie parameter, making cookie quoting behavior consistent for
    all cookies -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:2683, :issue:5397, :issue:7993, :issue:11112.

  • Fixed an issue where cookies with duplicate names but different domains or paths
    were lost when updating the cookie jar. The :class:~aiohttp.ClientSession
    cookie jar now correctly stores all cookies even if they have the same name but
    different domain or path, following the :rfc:6265#section-5.3 storage model -- by :user:bdraco.

    Note that :attr:ClientResponse.cookies <aiohttp.ClientResponse.cookies> returns
    a :class:~http.cookies.SimpleCookie which uses the cookie name as a key, so
    only the last cookie with each name is accessible via this interface. All cookies
    can be accessed via :meth:ClientResponse.headers.getall('Set-Cookie') <multidict.MultiDictProxy.getall> if needed.

Miscellaneous internal changes

  • Avoided creating closed futures in ResponseHandler that will never be awaited -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:11107.

  • Downgraded the logging level for connector close errors from ERROR to DEBUG, as these are expected behavior with TLS 1.3 connections -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:11114.


v3.12.6

Compare Source

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

Bug fixes

  • Fixed spurious "Future exception was never retrieved" warnings for connection lost errors when the connector is not closed -- by :user:bdraco.

    When connections are lost, the exception is now marked as retrieved since it is always propagated through other means, preventing unnecessary warnings in logs.

    Related issues and pull requests on GitHub:
    :issue:11100.


v3.12.4

Compare Source

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

Bug fixes

  • Fixed connector not waiting for connections to close before returning from :meth:~aiohttp.BaseConnector.close (partial backport of :pr:3733) -- by :user:atemate and :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:1925, :issue:11074.


v3.12.3

Compare Source

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

Bug fixes

  • Fixed memory leak in :py:meth:~aiohttp.CookieJar.filter_cookies that caused unbounded memory growth
    when making requests to different URL paths -- by :user:bdraco and :user:Cycloctane.

    Related issues and pull requests on GitHub:
    :issue:11052, :issue:11054.


v3.12.2

Compare Source

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

Bug fixes

  • Fixed Content-Length header not being set to 0 for non-GET requests with None body -- by :user:bdraco.

    Non-GET requests (POST, PUT, PATCH, DELETE) with None as the body now correctly set the Content-Length header to 0, matching the behavior of requests with empty bytes (b""). This regression was introduced in aiohttp 3.12.1.

    Related issues and pull requests on GitHub:
    :issue:11035.


v3.12.1

Compare Source

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

Bug fixes

  • Fixed cookie unquoting to properly handle octal escape sequences in cookie values (e.g., \012 for newline) by vendoring the correct _unquote implementation from Python's http.cookies module -- by :user:bdraco.

    Related issues and pull requests on GitHub:

v3.12.0

Compare Source

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

Bug fixes

  • Fixed :py:attr:~aiohttp.web.WebSocketResponse.prepared property to correctly reflect the prepared state, especially during timeout scenarios -- by :user:bdraco

    Related issues and pull requests on GitHub:
    :issue:6009, :issue:10988.

  • Response is now always True, instead of using MutableMapping behaviour (False when map is empty)

    Related issues and pull requests on GitHub:
    :issue:10119.

  • Fixed connection reuse for file-like data payloads by ensuring buffer
    truncation respects content-length boundaries and preventing premature
    connection closure race -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:10325, :issue:10915, :issue:10941, :issue:10943.

  • Fixed pytest plugin to not use deprecated :py:mod:asyncio policy APIs.

    Related issues and pull requests on GitHub:
    :issue:10851.

  • Fixed :py:class:~aiohttp.resolver.AsyncResolver not using the loop argument in versions 3.x where it should still be supported -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:10951.

Features

  • Added a comprehensive HTTP Digest Authentication client middleware (DigestAuthMiddleware)
    that implements RFC 7616. The middleware supports all standard hash algorithms
    (MD5, SHA, SHA-256, SHA-512) with session variants, handles both 'auth' and
    'auth-int' quality of protection options, and automatically manages the
    authentication flow by intercepting 401 responses and retrying with proper
    credentials -- by :user:feus4177, :user:TimMenninger, and :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:2213, :issue:10725.

  • Added client middleware support -- by :user:bdraco and :user:Dreamsorcerer.

    This change allows users to add middleware to the client session and requests, enabling features like
    authentication, logging, and request/response modification without modifying the core
    request logic. Additionally, the session attribute was added to ClientRequest,
    allowing middleware to access the session for making additional requests.

    Related issues and pull requests on GitHub:
    :issue:9732, :issue:10902, :issue:10945, :issue:10952, :issue:10959, :issue:10968.

  • Allow user setting zlib compression backend -- by :user:TimMenninger

    This change allows the user to call :func:aiohttp.set_zlib_backend() with the
    zlib compression module of their choice. Default behavior continues to use
    the builtin zlib library.

    Related issues and pull requests on GitHub:
    :issue:9798.

  • Added support for overriding the base URL with an absolute one in client sessions
    -- by :user:vivodi.

    Related issues and pull requests on GitHub:

  • Added socket_factory to :py:class:aiohttp.TCPConnector to allow specifying custom socket options
    -- by :user:TimMenninger.

    Related issues and pull requests on GitHub:
    :issue:10474, :issue:10520, :issue:10961, :issue:10962.

  • Started building armv7l manylinux wheels -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:10797.

  • Implemented shared DNS resolver management to fix excessive resolver object creation
    when using multiple client sessions. The new _DNSResolverManager singleton ensures
    only one DNSResolver object is created for default configurations, significantly
    reducing resource usage and improving performance for applications using multiple
    client sessions simultaneously -- by :user:bdraco.

    Related issues and pull requests on GitHub:
    :issue:10847, :issue:10923, :issue:10946.

  • Upgraded to LLHTTP 9.3.0 -- by :user:Dreamsorcerer.

    Related issues and pull requests on GitHub:
    :issue:10972.

  • Optimized small HTTP requests/responses by coalescing headers and body into a single TCP packet -- by :user:bdraco.

    This change enhances network efficiency by reducing the number of packets sent for small HTTP payloads, improving latency and reducing overhead. Most importantly, this fixes compatibility with memory-constrained IoT devices that can only perform a single read operation and expect HTTP requests in one packet. The optimization uses zero-copy writelines when coalescing data and works with both regular and chunked transfer encoding.

    When aiohttp uses client middleware to communicate with an aiohttp server, connection reuse is more likely to occur since complete responses arrive in a single packet for small payloads.

    This aligns aiohttp with other popular HTTP clients that already coalesce small requests.

    :issue:10991.

Improved documentation

  • Improved documentation for middleware by adding warnings and examples about
    request body stream consumption. The documentation now clearly explains that
    request body streams can only be read once and provides best practices for
    sharing parsed request data between middleware and handlers -- by :user:bdraco.

    :issue:2914.

Packaging updates and notes for downstreams

  • Removed non SPDX-license description from setup.cfg -- by :user:devanshu-ziphq.

    Related issues and pull requests on GitHub:
    :issue:10662.

  • Added support for building against system llhttp library -- by :user:mgorny.

    This change adds support for :envvar:AIOHTTP_USE_SYSTEM_DEPS environment variable that
    can be used to build aiohttp against the system install of the llhttp library rather
    than the vendored one.
