Release Notes

agronholm/anyio (anyio)

v4.14.0

Compare Source

• Added support for Python 3.15

• Added an asynchronous implementation of the itertools module (#​998; PR by @​11kkw)

• Added the local_port parameter to connect_tcp() to allow binding to a specific local port before connecting (#​1067; PR by @​nullwiz)

• Added support for custom capacity limiters in async path and file I/O functions and classes

• Added the create_task() task group method for easier asyncio migration (returns a TaskHandle) (#​1098)

• Changed TaskGroup.start_soon() to return a TaskHandle

• Added an option for TaskGroup.start() to return a TaskHandle (which then contains the start value in the start_value property)

• Added the cancel() convenience method to TaskGroup as a shortcut for cancelling the task group's cancel scope

• Improved the error message when a known backend is not installed to suggest the install command (#​1115; PR by @​EmmanuelNiyonshuti)

• Improved anyio.Path to preserve subclass types by returning Self in methods that return path objects (#​1130; PR by @​EmmanuelNiyonshuti)

• Changed the parameter type annotation in anyio.Path.write_bytes() to accept any ReadableBuffer, thus allowing it to accept bytearray and memoryview to match pathlib.Path.write_bytes() (#​1135; PR by @​SAY-5)

• Changed several type annotations to only accept callables returning coroutine-like objects instead of arbitrary awaitables:

  • TaskGroup.start_soon()
  • TaskGroup.start()
  • anyio.from_thread.run()

  This reverts an earlier change from v3.7.0 which was made in error. (#​1153)

• Changed anyio.run to support callables returning arbitrary awaitables at runtime on all backends. Previously, this only worked on asyncio (#​1171; PR by @​gschaffner)

• Changed several classes (and their subclasses) to have __slots__ (with __weakref__):

  • anyio.CancelScope
  • anyio.CapacityLimiter
  • anyio.Condition
  • anyio.Event
  • anyio.Lock
  • anyio.ResourceGuard
  • anyio.Semaphore

• Fixed cancellation exception escaping a cancel scope when triggered via check_cancelled() in a worker thread (#​1113)

• Fixed TaskGroup raising AttributeError instead of a clear error when entered more than once (#​1109; PR by @​bahtya)

• Fixed lost type information when passing arguments to lru_cache (#​1104; PR by @​Graeme22)

• Fixed test resumption after KeyboardInterrupt in async generator fixtures on the asyncio backend (#​1060; PR by @​EmmanuelNiyonshuti)

• Fixed import of __main__ in to_process workers when entrypoint script doesn't end in .py, such as when using console_script entrypoints. (#​1027; PR by @​tapetersen)

• Fixed SocketListener.from_socket() returning a TCP listener for AF_UNIX listening sockets, causing accept() to fail with ENOTSUP (#​1132; PR by @​kudato)

• Fixed UDPSocket.aclose() and ConnectedUDPSocket.aclose() on asyncio returning before the underlying socket FD was actually released (#​1147; PR by @​matias-arrelid)

• Fixed trio backend test runner hanging indefinitely instead of raising an error when dynamically accessing an async fixture via request.getfixturevalue (#​1148; PR by @​EmmanuelNiyonshuti)

• Fixed cancelling tasks started through a BlockingPortal after the portal has been stopped (#​1013; PR by @​puneetdixit200)

• Fixed backend_options being ignored when running the Trio backend via anyio.run(); the options are now passed as keyword arguments to trio.run() again, as documented (a regression from AnyIO 3) (#​1161; PR by @​Zac-HD)

• Fixed asyncio Lock and Semaphore deadlocks caused by cancelled waiters left queued during release (#​1145; PR by @​rasmusfaber, @​x42005e1f and @​agronholm)

• 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 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)

• 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 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

• 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 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)

v4.8.0

Compare Source

• Added experimental support for running functions in subinterpreters on Python 3.13 and later
• Added support for the copy(), copy_into(), move() and move_into() methods in anyio.Path, available in Python 3.14

• Configure SO_RCVBUF, SO_SNDBUF and TCP_NODELAY on the selector thread waker socket pair (this should improve the performance of wait_readable() and wait_writable() when using the ProactorEventLoop) (#​836; PR by @​graingert)
• Fixed AssertionError when using nest-asyncio (#​840)

v4.7.0

Compare Source

• Changed EventAdapter (an Event with no bound async backend) to allow set() to work even before an async backend is bound to it (#​819)
• Added support for wait_readable() and wait_writable() on ProactorEventLoop (used on asyncio + Windows by default)
• Fixed a misleading ValueError in the context of DNS failures (#​815; PR by @​graingert)

Compare Source

• Dropped support for Python 3.8 (as #​698 cannot be resolved without cancel message support)
• Fixed 100% CPU use on asyncio while waiting for an exiting task group to finish while said task group is within a cancelled cancel scope (#​695)
