Fix typo in Doc/library/asyncio-task.rst (GH-118627) 2024-05-06 08:00:31 -07:00

gh-116720: Fix corner cases of taskgroups (#117407) 
This prevents external cancellations of a task group's parent task to
be dropped when an internal cancellation happens at the same time.
Also strengthen the semantics of uncancel() to clear self._must_cancel
when the cancellation count reaches zero.

gh-77714: Provide an async iterator version of as_completed (GH-22491) 
* as_completed returns object that is both iterator and async iterator
* Existing tests adjusted to test both the old and new style
* New test to ensure iterator can be resumed
* New test to ensure async iterator yields any passed-in Futures as-is

Revert "Fix a code snippet typo in asyncio docs (#108427)" (GH-111271) 
This reverts commit 7f31676340.

The change resulted in a tautology and should not have been made.  There
may be an opportunity for additional clarity in this section, but this
change wasn't it :)

GH-94398: TaskGroup: Fail create_task() during shutdown (GH-94400) 
Once the task group is shutting down, it should not be possible to create a new task.
Here "shutting down" means `self._aborting` is set, indicating that at least one task
has failed and we have cancelled all others.

bpo-46829: Deprecate passing a message into Future.cancel() and Task.cancel() (GH-31840) 
After a long deliberation we ended up feeling that the message argument for Future.cancel(), added in 3.9, was a bad idea, so we're deprecating it in 3.11 and plan to remove it in 3.13.

bpo-43216: Remove @asyncio.coroutine (GH-26369) 
Remove the @asyncio.coroutine decorator
enabling legacy generator-based coroutines to be compatible with async/await
code; remove asyncio.coroutines.CoroWrapper used for wrapping
legacy coroutine objects in the debug mode.

The decorator has been deprecated
since Python 3.8 and the removal was initially scheduled for Python 3.10.
