Downgraded logging of invalid HTTP method exceptions on the first request to debug level -- by :user:bdraco.

HTTP requests starting with an invalid method are relatively common, especially when connected to the public internet, because browsers or other clients may try to speak SSL to a plain-text server or vice-versa. These exceptions can quickly fill the log with noise when nothing is wrong.

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.

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.

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.

Creating these objects without a running event loop was deprecated in :issue:3372 which was released in version 3.5.0.

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: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.

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.

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.

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.

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:
