Release Notes

agronholm/anyio (anyio)

v4.15.0

Compare Source

• Added support for the newer keyword-only arguments on anyio.Path methods to match the standard library pathlib.Path:

  • follow_symlinks on exists() (Python 3.12+)
  • follow_symlinks on is_dir() (Python 3.13+)
  • follow_symlinks on is_file() (Python 3.13+)
  • follow_symlinks on owner() (Python 3.13+)
  • follow_symlinks on group() (Python 3.13+)
  • newline on read_text() (Python 3.13+)

  (#​1286, #​1293; PR by @​jaideeppyne)

• Added amap, gather, and as_completed utility functions to simplify common patterns (#​1173; PR by @​Graeme22)

• Added --anyio-mode command-line option as an alternative to the anyio_mode ini setting, and fix the pytest plugin's auto mode detection to recognize the mode when set via either mechanism(e.g: pytest_asyncio). (#​1242; PR by @​EmmanuelNiyonshuti)

• Added the anyio.Future synchronization primitive which behaves similar to asyncio.Future, allowing tasks to wait for a value (or exception) from another task (#​1146; PR by @​Vizonex)

• Added guidance for managing multiple memory object stream producers and consumers with cloned streams (#​330; PR by @​nightcityblade)

• Added StapledObjectStream.send_nowait() that delegates to the underlying ObjectSendStream, if it implements it (#​1241; PR by @​davidbrochart)

• Added the move_on_at() and fail_at() functions to complement move_on_after() and fail_after()

• Changed the default name for a task spawned with TaskGroup.create_task(func()) to match the default task name for the analogous task spawned with TaskGroup.start_soon(func) or TaskGroup.start(func) in more situations. Previously, the default name of a TaskGroup.create_task task never included the module name. (The default name for a task spawned with TaskGroup.start_soon or TaskGroup.start typically includes the module name.) (#​1234; PR by @​gschaffner)

• Changed the anyio and anyio.abc modules to lazily (much like 810) import the necessary submodules. This is done by parsing the AST of the module and building a lookup table from the if TYPE_CHECKING: block. A fallback mode has been provided for installations where the source code is unavailable (e.g. PyInstaller). (#​1169)

• Fixed free-threading compatibility issues arising from the fact that on Python 3.14 free-threading builds, newly created threads inherit the current context by default, causing AnyIO to behave erroneously in relation to start_blocking_portal() and anyio.to_thread.run_sync() (#​1224; PR by @​EmmanuelNiyonshuti)

• Fixed SpooledTemporaryFile.readinto() and readinto1() reading twice before rollover, so the destination buffer was overwritten by the second read and the file position advanced twice, silently losing data (#​1215; PR by @​c-tonneslan)

• Added a reason parameter to fail_after (and the new fail_at) allowing for added exception context when raising TimeoutError (#​1227; PR by @​Graeme22)

• Fixed the default TaskHandle.name missing part of the task name for tasks started with TaskGroup.start on Trio (#​1231; PR by @​gschaffner)

• Fixed anyio.run leaking, or at least, delaying collection of loop and root_task due to the root task being cached in a RunVar. (#​1203; PR by @​tapetersen)

• Fixed anyio.Path.with_stem() silently producing a wrong path (e.g. Path(".txt")) instead of raising ValueError when given an empty stem on a path with a non-empty suffix, unlike pathlib.PurePath.with_stem (#​1200; PR by @​Sanjays2402)

• Fixed UNIXSocketStream.aclose() raising asyncio.InvalidStateError when a concurrent receive or send operation had just been cancelled on the asyncio backend (#​1267; PR by @​alloutflo)

• Fixed the pytest plugin importing the deprecated _pytest.python.CallSpec2 alias, which triggers PytestRemovedIn10Warning on pytest>=9.2 and crashes pytest at startup when filterwarnings = error is configured (#​1271; PR by @​matthewfeickert)

• Fixed an asyncio worker thread race that could raise RuntimeError when the event loop closed between checking its state and scheduling the worker result (#​1265; PR by @​hansu650)

• Fixed CapacityLimiter on the asyncio backend over-granting tokens when total_tokens was raised while the limiter was over-subscribed (#​1223; PR by @​zelinewang)

• Fixed asyncio task groups leaking unawaited coroutines when a custom task constructor fails; default task creation is unaffected (#​1274; PR by @​dsfaccini)

• Fixed inconsistencies between Trio and asyncio when target TaskGroup is cancelled before a task created with .start() calls TaskStatus.started()

  • The started task shouldn't get a CancelledError until the first checkpoint after the started() call.
  • A value passed to started() should be available on the TaskHandle and correctly passed back to the caller of start even if cancelled.
  • The CancelledError shouldn't leak out of the TaskGroup.start() call to the calling task.

  (#​1197; PR by @​tapetersen)

• Fixed TemporaryDirectory not cleaning up when the host task was cancelled while exiting the context manager, as the cleanup now runs in a shielded cancel scope (#​1304; PR by @​smurfix)

v4.14.2

Compare Source

• Changed ByteReceiveStream.receive() implementations to raise a ValueError when max_bytes is not a positive integer (#​1191)
• Fixed CapacityLimiter.total_tokens rejecting float("inf") when the limiter was instantiated outside of an event loop. The adapter setter checked for infinity by identity (value is math.inf), so only the exact math.inf singleton was accepted, while every backend setter (using math.isinf()) accepts any positive infinity (#​1189; PR by @​greymoth-jp).
• Fixed to_process.run_sync() deadlocking when the worker function writes enough data to sys.stderr to fill the (undrained) pipe buffer. The worker process now redirects sys.stderr to os.devnull as well, matching the documented behavior
• Fixed TLSStream.wrap() matching an internationalized (unicode) host name against the peer certificate using IDNA 2003 (via the standard library) instead of IDNA 2008, which could cause the host name to be matched against the wrong certificate (#​1208)
• Fixed anyio.open_process() (and run_process()) ignoring the extra_groups argument, as it mistakenly passed the value of the group argument instead (#​1209)
• Fixed CapacityLimiter.acquire_nowait() and CapacityLimiter.acquire_nowait_on_behalf_of() raising trio.WouldBlock instead of anyio.WouldBlock on the trio backend when there are no tokens available (#​1218)
• Fixed CapacityLimiter on the asyncio backend over-granting tokens (borrowed_tokens exceeding total_tokens and available_tokens going negative) when a non-blocking acquire was made in the window between a token being released and the notified waiter resuming. The freed token is now reserved for the woken waiter right away, so the non-blocking acquire correctly raises WouldBlock (#​1170; PR by @​gaoflow)
• Fixed unnecessary CPU spin when delivering cancellation from CancelScope on asyncio under certain conditions, including improper cancel scope nesting (#​1111)

v4.14.1

Compare Source

• Fixed teardown of higher-scoped async fixtures failing on asyncio with RuntimeError: Attempted to exit cancel scope in a different task than it was entered in when an async test raise an outcome exception (e.g., pytest.skip(), pytest.xfail(), or pytest.fail()) (#​1179; PR by @​EmmanuelNiyonshuti)
• Fixed CapacityLimiter.total_tokens rejecting a value of 0 when the limiter was instantiated outside of an event loop, contradicting the documented behavior of allowing 0 total tokens (#​1183; PR by @​nyxst4ck)
