agronholm/anyio 4.2.0

on GitHub

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:

• anyio.run()
• TaskGroup.start_soon()
• anyio.from_thread.run()
• anyio.from_thread.run_sync()
• anyio.to_thread.run_sync()
• anyio.to_process.run_sync()
• BlockingPortal.call()
• BlockingPortal.start_task_soon()
• BlockingPortal.start_task()

(also resolves #560)

Fixed various type annotations of anyio.Path to match Typeshed:

• anyio.Path.__lt__()
• anyio.Path.__le__()
• anyio.Path.__gt__()
• anyio.Path.__ge__()
• anyio.Path.__truediv__()
• anyio.Path.__rtruediv__()
• anyio.Path.hardlink_to()
• anyio.Path.samefile()
• anyio.Path.symlink_to()
• anyio.Path.with_segments()

(PR by Ganden Schaffner)

Fixed adjusting the total number of tokens in a CapacityLimiter on asyncio failing to wake up tasks waiting to acquire the limiter in certain edge cases (fixed with help from Egor Blagov)

Fixed loop_factory and use_uvloop options not being used on the asyncio backend (#643)

Fixed cancellation propagating on asyncio from a task group to child tasks if the task hosting the task group is in a shielded cancel scope (#642)
