Release Notes

agronholm/anyio (anyio)

v4.13.0

Compare Source

• Dropped support for Python 3.9
• Added a ttl parameter to the anyio.functools.lru_cache wrapper (#​1073; PR by @​Graeme22)
• Widened the type annotations of file I/O streams to accept IO[bytes] instead of just BinaryIO (#​1078)
• Fixed anyio.Path not being compatible with Python 3.15 due to the removal of pathlib.Path.is_reserved() and the addition of pathlib.Path.__vfspath__() (#​1061; PR by @​veeceey)
• Fixed the BrokenResourceError raised by the asyncio SocketStream not having the original exception as its cause (#​1055; PR by @​veeceey)
• Fixed the TypeError raised when using "func" as a parameter name in pytest.mark.parametrize when using the pytest plugin (#​1068; PR by @​JohnnyDeuss)
• Fixed the pytest plugin not running tests that had the anyio marker added programmatically via pytest_collection_modifyitems (#​422; PR by @​chbndrhnns)
• Fixed cancellation exceptions leaking from a CancelScope on asyncio when they are contained in an exception group alongside non-cancellation exceptions (#​1091; PR by @​gschaffner)
• Fixed Condition.wait() not passing on a notification when the task is cancelled but already received a notification
• Fixed inverted condition in the process pool shutdown phase which would cause still-running pooled processes not to be terminated (#​1074; PR by @​bysiber)

v4.12.1

Compare Source

• Changed all functions currently raising the private NoCurrentAsyncBackend exception (since v4.12.0) to instead raise the public NoEventLoopError exception (#​1048)
• Fixed anyio.functools.lru_cache not working with instance methods (#​1042)

v4.12.0

Compare Source

• Added support for asyncio's task call graphs on Python 3.14 and later when using AnyIO's task groups (#​1025)
• Added an asynchronous implementation of the functools module (#​1001)
• Added support for uvloop=True on Windows via the winloop implementation (#​960; PR by @​Vizonex)
• Added support for use as a context manager to anyio.lowlevel.RunVar (#​1003)
• Added __all__ declarations to public submodules (anyio.lowlevel etc.) (#​1009)
• Added the ability to set the token count of a CapacityLimiter to zero (#​1019; requires Python 3.10 or later when using Trio)
• Added parameters case_sensitive and recurse_symlinks along with support for path-like objects to anyio.Path.glob() and anyio.Path.rglob() (#​1033; PR by @​northisup)
• Dropped sniffio as a direct dependency and added the get_available_backends() function (#​1021)
• Fixed Process.stdin.send() not raising ClosedResourceError and BrokenResourceError on asyncio. Previously, a non-AnyIO exception was raised in such cases (#​671; PR by @​gschaffner)
• Fixed Process.stdin.send() not checkpointing before writing data on asyncio (#​1002; PR by @​gschaffner)
• Fixed a race condition where cancelling a Future from BlockingPortal.start_task_soon() would sometimes not cancel the async function (#​1011; PR by @​gschaffner)
• Fixed the presence of the pytest plugin causing breakage with older versions of pytest (<= 6.1.2) (#​1028; PR by @​saper)
• Fixed a rarely occurring RuntimeError: Set changed size during iteration while shutting down the process pool when using the asyncio backend (#​985)

v4.11.0

Compare Source

• Added support for cancellation reasons (the reason parameter to CancelScope.cancel()) (#​975)
• Bumped the minimum version of Trio to v0.31.0
• Added the ability to enter the event loop from foreign (non-worker) threads by passing the return value of anyio.lowlevel.current_token() to anyio.from_thread.run() and anyio.from_thread.run_sync() as the token keyword argument (#​256)
• Added pytest option (anyio_mode = "auto") to make the pytest plugin automatically handle all async tests (#​971)
• Added the anyio.Condition.wait_for() method for feature parity with asyncio (#​974)
• Changed the default type argument of anyio.abc.TaskStatus from Any to None (#​964)
• Fixed TCP listener behavior to guarantee the same ephemeral port is used for all socket listeners when local_port=0 (#​857; PR by @​11kkw and @​agronholm)
• Fixed inconsistency between Trio and asyncio where a TCP stream that previously raised a BrokenResourceError on send() would still raise BrokenResourceError after the stream was closed on asyncio, but ClosedResourceError on Trio. They now both raise a ClosedResourceError in this scenario. (#​671)

v4.10.0

Compare Source

• Added the feed_data() method to the BufferedByteReceiveStream class, allowing users to inject data directly into the buffer
• Added various class methods to wrap existing sockets as listeners or socket streams:
  • SocketListener.from_socket()
  • SocketStream.from_socket()
  • UNIXSocketStream.from_socket()
  • UDPSocket.from_socket()
  • ConnectedUDPSocket.from_socket()
  • UNIXDatagramSocket.from_socket()
  • ConnectedUNIXDatagramSocket.from_socket()
• Added a hierarchy of connectable stream classes for transparently connecting to various remote or local endpoints for exchanging bytes or objects
• Added context manager mix-in classes (anyio.ContextManagerMixin and anyio.AsyncContextManagerMixin) to help write classes that embed other context managers, particularly cancel scopes or task groups (#​905; PR by @​agronholm and @​tapetersen)
• Added the ability to specify the thread name in start_blocking_portal() (#​818; PR by @​davidbrochart)
• Added anyio.notify_closing to allow waking anyio.wait_readable and anyio.wait_writable before closing a socket. Among other things, this prevents an OSError on the ProactorEventLoop. (#​896; PR by @​graingert)
• Incorporated several documentation improvements from the EuroPython 2025 sprint (special thanks to the sprinters: Emmanuel Okedele, Jan Murre, Euxenia Miruna Goia and Christoffer Fjord)
• Added a documentation page explaining why one might want to use AnyIO's APIs instead of asyncio's
• Updated the to_interpreters module to use the public concurrent.interpreters API on Python 3.14 or later
• Fixed anyio.Path.copy() and anyio.Path.copy_into() failing on Python 3.14.0a7
• Fixed return annotation of __aexit__ on async context managers. CMs which can suppress exceptions should return bool, or None otherwise. (#​913; PR by @​Enegg)
• Fixed rollover boundary check in SpooledTemporaryFile so that rollover only occurs when the buffer size exceeds max_size (#​915; PR by @​11kkw)
• Migrated testing and documentation dependencies from extras to dependency groups
• Fixed compatibility of anyio.to_interpreter with Python 3.14.0b2 (#​926; PR by @​hroncok)
• Fixed SyntaxWarning on Python 3.14 about return in finally (#​816)
• Fixed RunVar name conflicts. RunVar instances with the same name should not share storage (#​880; PR by @​vimfu)
• Renamed the BrokenWorkerIntepreter exception to BrokenWorkerInterpreter. The old name is available as a deprecated alias. (#​938; PR by @​ayussh-verma)
• Fixed an edge case in CapacityLimiter on asyncio where a task, waiting to acquire a limiter gets cancelled and is subsequently granted a token from the limiter, but before the cancellation is delivered, and then fails to notify the next waiting task (#​947)

v4.9.0

Compare Source

• Added async support for temporary file handling (#​344; PR by @​11kkw)
• Added 4 new fixtures for the AnyIO pytest plugin:
  • free_tcp_port_factory: session scoped fixture returning a callable that generates unused TCP port numbers
  • free_udp_port_factory: session scoped fixture returning a callable that generates unused UDP port numbers
  • free_tcp_port: function scoped fixture that invokes the free_tcp_port_factory fixture to generate a free TCP port number
  • free_udp_port: function scoped fixture that invokes the free_udp_port_factory fixture to generate a free UDP port number
• Added stdin argument to anyio.run_process() akin to what anyio.open_process(), asyncio.create_subprocess(), trio.run_process(), and subprocess.run() already accept (PR by @​jmehnle)
• Added the info property to anyio.Path on Python 3.14
• Changed anyio.getaddrinfo() to ignore (invalid) IPv6 name resolution results when IPv6 support is disabled in Python
• Changed EndOfStream raised from MemoryObjectReceiveStream.receive() to leave out the AttributeError from the exception chain which was merely an implementation detail and caused some confusion
• Fixed traceback formatting growing quadratically with level of TaskGroup nesting on asyncio due to exception chaining when raising ExceptionGroups in TaskGroup.__aexit__ (#​863; PR by @​tapetersen)
• Fixed anyio.Path.iterdir() making a blocking call in Python 3.13 (#​873; PR by @​cbornet and @​agronholm)
• Fixed connect_tcp() producing cyclic references in tracebacks when raising exceptions (#​809; PR by @​graingert)
• Fixed anyio.to_thread.run_sync() needlessly holding on to references of the context, function, arguments and others until the next work item on asyncio (PR by @​Wankupi)
