Changelog

Unreleased

  • Added PyAwaitable_AddExpr.
  • Fix assertion failures when running in debug mode.

[2.0.1] - 2025-06-15

  • Pinned dependencies to a specific version to prevent incompatibility problems.

[2.0.0] - 2025-03-30

  • Moved away from function pointer tables for loading PyAwaitable--everything is now vendored upon installation.
  • Improved performance with compiler optimizations.
  • PyAwaitable_ prefixes are now required, and the old pyawaitable_* functions have been removed.
  • The warning emitted when a PyAwaitable object is not awaited is now a ResourceWarning (was a RuntimeWarning).
  • PyAwaitable_AddAwait now raises a ValueError if the passed object is NULL or self, and also now raises a TypeError if the passed object is not a coroutine.
  • Added a simple CLI, primarily for getting the include directory from meson-python (pyawaitable --include).
  • PyAwaitable objects now support garbage collection.
  • Breaking Change: PyAwaitable_Init no longer takes a module object.
  • Breaking Change: Renamed awaitcallback to PyAwaitable_Callback
  • Breaking Change: Renamed awaitcallback_err to PyAwaitable_Error
  • Breaking Change: Renamed defercallback to PyAwaitable_Defer
  • Breaking Change: Removed the integer value APIs (SaveIntValues, LoadIntValues, SetIntValue, GetIntValue). They proved to be maintenance heavy, unintuitive, and most of all replaceable with the arbitrary values API (via mallocing an integer and storing it).

[1.4.0] - 2025-02-09

  • Significantly reduced awaitable object size by dynamically allocating it.
  • Reduced memory footprint by removing preallocated awaitable objects.
  • Objects returned by a PyAwaitable object's __await__ are now garbage collected (i.e., they don't leak with rare circular references).
  • Removed limit on number of stored callbacks or values.
  • Switched some user-error messages to RuntimeError instead of SystemError.
  • Added PyAwaitable_DeferAwait for executing code without a coroutine when the awaitable object is called by the event loop.

[1.3.0] - 2024-10-26

  • Added support for async with via pyawaitable_async_with.

[1.2.0] - 2024-08-06

  • Added getting and setting of value storage.

[1.1.0] - 2024-08-03

  • Changed error message when attempting to await a non-awaitable object (i.e., it has no __await__).
  • Fixed coroutine iterator reference leak.
  • Fixed reference leak in error callbacks.
  • Fixed early exit of pyawaitable_unpack_arb if a NULL value was saved.
  • Added integer value saving and unpacking (pyawaitable_save_int and pyawaitable_unpack_int).
  • Callbacks are now preallocated for better performance.
  • Fixed reference leak in the coroutine send() method.

[1.0.0] - 2024-06-24

  • Initial release.
