Bump anyio from 3.6.2 to 4.9.0

[dependabot]

Bumps anyio from 3.6.2 to 4.9.0.

Release notes

Sourced from anyio's releases.

4.9.0

• 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)

4.8.0

• 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
• Changed TaskGroup on asyncio to always spawn tasks non-eagerly, even if using a task factory created via asyncio.create_eager_task_factory(), to preserve expected Trio-like task scheduling semantics (PR by @​agronholm and @​graingert)
• 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)
• Fixed return type annotation of various context managers' __exit__ method (#847; PR by @​Enegg)

4.7.0

• Updated TaskGroup to work with asyncio's eager task factories (#764)
• Added the wait_readable() and wait_writable() functions which will accept an object with a .fileno() method or an integer handle, and deprecated their now obsolete versions (wait_socket_readable() and wait_socket_writable()) (PR by @​davidbrochart)
• 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)
• Fixed the return type annotations of readinto() and readinto1() methods in the anyio.AsyncFile class (#825)
• Fixed TaskInfo.has_pending_cancellation() on asyncio returning false positives in cleanup code on Python >= 3.11 (#832; PR by @​gschaffner)
• Fixed cancelled cancel scopes on asyncio calling asyncio.Task.uncancel when propagating a CancelledError on exit to a cancelled parent scope (#790; PR by @​gschaffner)

4.6.2

• Fixed regression caused by (#807) that prevented the use of parametrized async fixtures

4.6.1

This release contains all the changes from both v4.5.1 and v4.6.0, plus:

• Fixed TaskGroup and CancelScope producing cyclic references in tracebacks when raising exceptions (#806) (PR by @​graingert)

4.6.0

• 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)
• Fixed cancel scopes on asyncio not propagating CancelledError on exit when the enclosing cancel scope has been effectively cancelled (#698)
• Fixed asyncio task groups not yielding control to the event loop at exit if there were no child tasks to wait on
• Fixed inconsistent task uncancellation with asyncio cancel scopes belonging to a task group when said task group has child tasks running

4.5.2

Version history

This library adheres to Semantic Versioning 2.0 <http://semver.org/>_.

UNRELEASED

• 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](https://github.com/agronholm/anyio/issues/905) <https://github.com/agronholm/anyio/pull/905>_; PR by by @​agronholm and @​tapetersen)

• Added the ability to specify the thread name in start_blocking_portal() ([#818](https://github.com/agronholm/anyio/issues/818) <https://github.com/agronholm/anyio/issues/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](https://github.com/agronholm/anyio/issues/896) <https://github.com/agronholm/anyio/pull/896>_; PR by @​graingert)

• 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](https://github.com/agronholm/anyio/issues/913) <https://github.com/agronholm/anyio/pull/913>_; PR by @​Enegg)

• Fixed rollover boundary check in SpooledTemporaryFile so that rollover only occurs when the buffer size exceeds max_size ([#915](https://github.com/agronholm/anyio/issues/915) <https://github.com/agronholm/anyio/pull/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](https://github.com/agronholm/anyio/issues/926) <https://github.com/agronholm/anyio/issues/926>_; PR by @​hroncok)

• Fixed SyntaxWarning on Python 3.14 about return in finally ([#816](https://github.com/agronholm/anyio/issues/816) <https://github.com/agronholm/anyio/issues/816>_)

• Fixed RunVar name conflicts. RunVar instances with the same name should not share storage. ([#880](https://github.com/agronholm/anyio/issues/880) <https://github.com/agronholm/anyio/issues/880>_; PR by @​vimfu)

4.9.0

• Added async support for temporary file handling ([#344](https://github.com/agronholm/anyio/issues/344) <https://github.com/agronholm/anyio/issues/344>_; PR by @​11kkw)
• Added 4 new fixtures for the AnyIO pytest plugin:
