* bpo-46955: Expose asyncio.base_events.Server as asyncio.Server (GH-31760)Stefan Zabka2022-03-081-1/+1
| | | | | | This change aligns the documentation at https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.Server with the actual implementation Co-authored-by: Andrew Svetlov <andrew.svetlov@gmail.com>

* bpo-46771: Remove two controversial lines from Task.cancel() (GH-31623)Guido van Rossum2022-02-281-2/+5
| | | | | | | | | | | | | | | Also from the _asyncio C accelerator module, and adjust one test that the change caused to fail. For more discussion see the discussion starting here: https://github.com/python/cpython/pull/31394#issuecomment-1053545331 (Basically, @asvetlov proposed to return False from cancel() when there is already a pending cancellation, and I went along, even though it wasn't necessary for the task group implementation, and @agronholm has come up with a counterexample that fails because of this change. So now I'm changing it back to the old semantics (but still bumping the counter) until we can have a proper discussion about this.)
* Taskgroup tweaks (GH-31559)Tin Tvrtković2022-02-261-27/+23
| | | Now uses .cancel()/.uncancel(), for even fewer broken edge cases.
* bpo-46771: Implement task cancel requests counter (GH-31513)Tin Tvrtković2022-02-241-9/+21
| | | | | This changes cancelling() and uncancel() to return the count of pending cancellations. This can be used to avoid bugs in certain edge cases (e.g. two timeouts going off at the same time).

| | | | | | | | | | | | | | | | | * Remove task group names (for now) We're not sure that they are needed, and once in the code we would never be able to get rid of them.

* bpo-46752: Add TaskGroup; add Task..cancelled(),.uncancel() (GH-31270)Guido van Rossum2022-02-154-2/+252
| | | | | | | | | | | | | | | | | asyncio/taskgroups.py is an adaptation of taskgroup.py from EdgeDb, with the following key changes: - Allow creating new tasks as long as the last task hasn't finished - Raise [Base]ExceptionGroup (directly) rather than TaskGroupError deriving from MultiError - Instead of monkey-patching the parent task's cancel() method, add a new public API to Task The Task class has a new internal flag, `_cancel_requested`, which is set when `.cancel()` is called successfully. The `.cancelling()` method returns the value of this flag. Further `.cancel()` calls while this flag is set return False. To reset this flag, call `.uncancel()`. Thus, a Task that catches and ignores `CancelledError` should call `.uncancel()` if it wants to be cancellable again; until it does so, it is deemed to be busy with uninterruptible cleanup. This new Task API helps solve the problem where TaskGroup needs to distinguish between whether the parent task being cancelled "from the outside" vs. "from inside".

* bpo-43945: [Enum] reduce scope of new format() behavior (GH-26752)Ethan Furman2021-06-181-2/+2
| | | | | | | | | | | | | | | | | | | | | * [Enum] reduce scope of new format behavior Instead of treating all Enums the same for format(), only user mixed-in enums will be affected. In other words, IntEnum and IntFlag will not be changing the format() behavior, due to the requirement that they be drop-in replacements of existing integer constants. If a user creates their own integer-based enum, then the new behavior will apply: class Grades(int, Enum): A = 5 B = 4 C = 3 D = 2 F = 0 Now: format(Grades.B) -> DeprecationWarning and '4' 3.12: -> no warning, and 'B'
