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:
    #6009, #10988.

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

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

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

    Related issues and pull requests on GitHub:
    #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.

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.

    #2213, #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.

  • 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.

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

  • Added host parameter to aiohttp_server fixture -- by :user:christianwbrock.

  • Detect blocking calls in coroutines using BlockBuster -- by :user:cbornet.

    Related issues and pull requests on GitHub:
    #10433.

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

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

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

    Related issues and pull requests on GitHub:
    #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.

    #10847, #10923, #10946.

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

    Related issues and pull requests on GitHub:
    #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.

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.

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:
    #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.

  • aiodns is now installed on Windows with speedups extra -- by :user:bdraco.

    As of aiodns 3.3.0, SelectorEventLoop is no longer required when using pycares 4.7.0 or later.

    Related issues and pull requests on GitHub:
