Version history

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

UNRELEASED

• Added the BlockingPortalProvider class to aid with constructing synchronous counterparts to asynchronous interfaces that would otherwise require multiple blocking portals
• Fixed erroneous RuntimeError: called 'started' twice on the same task status when cancelling a task in a TaskGroup created with the start() method before the first checkpoint is reached after calling task_status.started() ([#706](https://github.com/agronholm/anyio/issues/706) <https://github.com/agronholm/anyio/issues/706>_; PR by Dominik Schwabe)
• Fixed cancellation delivery on asyncio incrementing the wrong cancel scope's cancellation counter when cascading a cancel operation to a child scope, thus failing to uncancel the host task ([#716](https://github.com/agronholm/anyio/issues/716) <https://github.com/agronholm/anyio/issues/716>_)
• Fixed erroneous TypedAttributeLookupError if a typed attribute getter raises KeyError
• Fixed the asyncio backend not respecting the PYTHONASYNCIODEBUG environment variable when setting the debug flag in anyio.run()
• Fixed SocketStream.receive() not detecting EOF on asyncio if there is also data in the read buffer ([#701](https://github.com/agronholm/anyio/issues/701) <https://github.com/agronholm/anyio/issues/701>_)
• Emit a ResourceWarning for MemoryObjectReceiveStream and MemoryObjectSendStream that were garbage collected without being closed (PR by Andrey Kazantcev)

4.3.0

• Added support for the Python 3.12 walk_up keyword argument in anyio.Path.relative_to() (PR by Colin Taylor)

• Fixed passing total_tokens to anyio.CapacityLimiter() as a keyword argument not working on the trio backend ([#515](https://github.com/agronholm/anyio/issues/515) <https://github.com/agronholm/anyio/issues/515>_)

• Fixed Process.aclose() not performing the minimum level of necessary cleanup when cancelled. Previously:

  • Cancellation of Process.aclose() could leak an orphan process
  • Cancellation of run_process() could very briefly leak an orphan process.
  • Cancellation of Process.aclose() or run_process() on Trio could leave standard streams unclosed

  (PR by Ganden Schaffner)

• Fixed Process.stdin.aclose(), Process.stdout.aclose(), and Process.stderr.aclose() not including a checkpoint on asyncio (PR by Ganden Schaffner)

• Fixed documentation on how to provide your own typed attributes

4.2.0
