  • Replaced code that can now be handled by yarl -- by :user:`bdraco`.

    Related issues and pull requests on GitHub: :issue:`9301`.

3.10.6 (2024-09-24)

Bug fixes

Features

Removals and backward incompatible breaking changes

  • Improved middleware performance -- by :user:`bdraco`.

    The set_current_app method was removed from UrlMappingMatchInfo because it is no longer used, and it was unlikely external caller would ever use it.

    Related issues and pull requests on GitHub: :issue:`9200`.

  • Increased minimum yarl version to 1.12.0 -- by :user:`bdraco`.

    Related issues and pull requests on GitHub: :issue:`9267`.

Packaging updates and notes for downstreams

Miscellaneous internal changes

3.10.5 (2024-08-19)

Bug fixes

Miscellaneous internal changes

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

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

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

Removals and backward incompatible breaking changes

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`.

    -- 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`.

  • 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 and are not known to be of any legitimate use.

    Related issues and pull requests on GitHub: :issue:`8074`.

  • Improved validation of paths for static resources requests to the server -- by :user:`bdraco`.

    Related issues and pull requests on GitHub: :issue:`8079`.

    #7561

Features

  • Enabled lenient response parsing for more flexible parsing in the client (this should resolve some regressions when dealing with badly formatted HTTP responses). -- by :user:`Dreamsorcerer`

    #7490

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

3.8.2 (2022-09-20, subsequently yanked on 2022-09-21)

Bugfixes

Improved Documentation

Deprecations and Removals

  • Drop Python 3.5 support, aiohttp works on 3.6+ now. #4046

Misc

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 an index out of range error in aiohttp. For example, if user compile CPython with --disable-ipv6 option, but his system enable the ipv6. #5901
  • Do not install "examples" as a top-level package. #6189
  • Restored ability to connect IPv6-only host. #6195
  • Remove Signal from __all__, replace aiohttp.Signal with aiosignal.Signal in docs #6201

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. #2988

  • Switch from http-parser to llhttp #3561

  • Use Brotli instead of brotlipy #3803

  • 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. #3828

  • Make access log use local time with timezone #3853

  • Implemented readuntil in StreamResponse #4054

  • FileResponse now supports ETag. #4594

  • Add a request handler type alias aiohttp.typedefs.Handler. #4686

  • 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. #4700

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)
  • Bump C HTTP parser to version 2.8 (#2730)
  • Accept a coroutine as an application factory in web.run_app and gunicorn worker. (#2739)
  • Implement application cleanup context (app.cleanup_ctx property). (#2747)
  • Make writer.write_headers a coroutine. (#2762)
  • Add tracking signals for getting request/response bodies. (#2767)
  • Deprecate ClientResponseError.code in favor of .status to keep similarity with response classes. (#2781)
  • Implement app.add_routes() method. (#2787)
  • Implement web.static() and RouteTableDef.static() API. (#2795)
  • 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)
  • Refactor ClientResponse constructor: make logically required constructor arguments mandatory, drop _post_init() method. (#2820)
  • Use app.add_routes() in server docs everywhere (#2830)
  • Websockets refactoring, all websocket writer methods are converted into coroutines. (#2836)

3.0.6 (2018-03-05)

  • Add _reuse_address and _reuse_port to web_runner.TCPSite.__slots__. (#2792)
