0.14.0

Added

• Experimental curio support.

Changed

• Support for libraries has been redefined with wrapt via post import hooks. Previously, available libraries were determined after the first use, which could lead to unexpected behavior in interactive scenarios. Now support for a library is activated when the corresponding library is imported.
• Support for greenlet-based libraries has been simplified. Detecting the current green library is now done by hub: if any eventlet or gevent function was called in the current thread, the current thread starts using the corresponding library. This eliminates the need to specify a green library both before and after monkey patching.
• Corrected type annotations:
  • aiologic.BoundedSemaphore extends aiologic.Semaphore, and aiologic.Semaphore returns an instance of aiologic.BoundedSemaphore when passing max_value. Previously, the classes were independent in stubs, which was inconsistent with the behavior added in 0.2.0.
  • aiologic.lowlevel.current_thread() returns Optional[threading.Thread]. Previously, threading.Thread was returned, which was inconsistent with the special handling of threading._DummyThread.

Removed

• Aliases to old modules (affects objects pickled before 0.13.0).
• Patcher-related exports (such as aiologic.lowlevel.start_new_thread()).
• aiologic.lowlevel.current_async_library_cvar: the sniffio equivalent is deprecated and not used by modern libraries, and the performance impact of using it is only negative.

Fixed

• asyncio was not considered running when the current task was None. This resulted in the inability to use any async functions in asyncio REPR without explicitly setting the current async library. Related: python-trio/sniffio#35.
• There was a missing branch for the optimistic case of non-waiting lock acquiring during race condition, which caused hangs in a free-threaded mode (0.13.1 regression).
