Added the BlockingPortalProvider class to aid with constructing synchronous counterparts to asynchronous interfaces that would otherwise require multiple blocking portals
Added __slots__ to AsyncResource so that child classes can use __slots__ (#733; PR by Justin Su)
Added the TaskInfo.has_pending_cancellation() method
Fixed erroneous RuntimeError: called 'started' twice on the same task status when cancelling a task in a TaskGroup created with the start() method before the first checkpoint is reached after calling task_status.started() (#706; PR by Dominik Schwabe)
Fixed two bugs with TaskGroup.start() on asyncio:
Fixed erroneous RuntimeError: called 'started' twice on the same task status when cancelling a task in a TaskGroup created with the start() method before the first checkpoint is reached after calling task_status.started() (#706; PR by Dominik Schwabe)
Fixed the entire task group being cancelled if a TaskGroup.start() call gets cancelled (#685, #710)
Fixed a race condition that caused crashes when multiple event loops of the same backend were running in separate threads and simultaneously attempted to use AnyIO for their first time (#425; PR by David Jiricek and Ganden Schaffner)
Fixed cancellation delivery on asyncio incrementing the wrong cancel scope's cancellation counter when cascading a cancel operation to a child scope, thus failing to uncancel the host task (#716)
Fixed erroneous TypedAttributeLookupError if a typed attribute getter raises KeyError
Fixed the asyncio backend not respecting the PYTHONASYNCIODEBUG environment variable when setting the debug flag in anyio.run()
Fixed SocketStream.receive() not detecting EOF on asyncio if there is also data in the read buffer (#701)
Fixed MemoryObjectStream dropping an item if the item is delivered to a recipient that is waiting to receive an item but has a cancellation pending (#728)
Emit a ResourceWarning for MemoryObjectReceiveStream and MemoryObjectSendStream that were garbage collected without being closed (PR by Andrey Kazantcev)
Fixed MemoryObjectSendStream.send() not raising BrokenResourceError when the last corresponding MemoryObjectReceiveStream is closed while waiting to send a falsey item (#731; PR by Ganden Schaffner)
4.3.0
Added support for the Python 3.12 walk_up keyword argument in anyio.Path.relative_to() (PR by Colin Taylor)
Fixed passing total_tokens to anyio.CapacityLimiter() as a keyword argument not working on the trio backend (#515)
Fixed Process.aclose() not performing the minimum level of necessary cleanup when cancelled. Previously:
Cancellation of Process.aclose() could leak an orphan process
Cancellation of run_process() could very briefly leak an orphan process.
Cancellation of Process.aclose() or run_process() on Trio could leave standard streams unclosed
(PR by Ganden Schaffner)
Fixed Process.stdin.aclose(), Process.stdout.aclose(), and Process.stderr.aclose() not including a checkpoint on asyncio (PR by Ganden Schaffner)
Fixed documentation on how to provide your own typed attributes
4.2.0
Add support for byte-based paths in connect_unix, create_unix_listeners, create_unix_datagram_socket, and create_connected_unix_datagram_socket. (PR by Lura Skye)
Enabled the Event and CapacityLimiter classes to be instantiated outside an event loop thread
Broadly improved/fixed the type annotations. Among other things, many functions and methods that take variadic positional arguments now make use of PEP 646 TypeVarTuple to allow the positional arguments to be validated by static type checkers. These changes affected numerous methods and functions, including:
This library adheres to Semantic Versioning 2.0 <http://semver.org/>_.
