* gh-128002: fix many thread safety issues in asyncio (#128147)Kumar Aditya2025-01-043-175/+951
| | | | | | * Makes `_asyncio.Task` and `_asyncio.Future` thread-safe by adding critical sections * Add assertions to check for thread safety checking locking of object by critical sections in internal functions * Make `_asyncio.all_tasks` thread safe when eager tasks are used * Add a thread safety test
* gh-125985: Fix `cmodule_function()` scaling benchmark (#128460)Sam Gross2025-01-031-3/+11
| | | | | | | | | | | Add a separate benchmark that measures the effect of `_PyObject_LookupSpecial()` on scaling. In the process of cleaning up the scaling benchmarks for inclusion, I unintentionally changed the "cmodule_function" benchmark to pass an `int` to `math.floor()` instead of a `float`, which causes it to use the `_PyObject_LookupSpecial()` code path. `_PyObject_LookupSpecial()` has its own scaling issues that we want to measure separately from calling a function on a C module.

* gh-127787: refactor helpers for `PyUnicodeErrorObject` internal interface ↵Bénédikt Tran2025-01-032-155/+293
| | | | | | | | | | | | | | | | | | | | | | (GH-127789) - Unify `get_unicode` and `get_string` in a single function. - Allow to retrieve the underlying `object` attribute, its size, and the adjusted 'start' and 'end', all at once. Add a new `_PyUnicodeError_GetParams` internal function for this. (In `exceptions.c`, it's somewhat common to not need all the attributes, but the compiler has opportunity to inline the function and optimize unneeded work away. Outside that file, we'll usually need all or most of them at once.) - Use a common implementation for the following functions: - `PyUnicode{Decode,Encode}Error_GetEncoding` - `PyUnicode{Decode,Encode,Translate}Error_GetObject` - `PyUnicode{Decode,Encode,Translate}Error_{Get,Set}Reason` - `PyUnicode{Decode,Encode,Translate}Error_{Get,Set}{Start,End}`

* Remove asserts that confuse `enum _framestate` with `enum _frameowner` ↵Anders Kaseorg2025-01-021-2/+0
| | | | | | | | | | | | (GH-124148) The `owner` field of `_PyInterpreterFrame` is supposed to be a member of `enum _frameowner`, but `FRAME_CLEARED` is a member of `enum _framestate`. At present, it happens that `FRAME_CLEARED` is not numerically equal to any member of `enum _frameowner`, but that could change in the future. The code that incorrectly assigned `owner = FRAME_CLEARED` was deleted in commit a53cc3f49463e50cb3e2b839b3a82e6bf7f73fee (GH-116687). Remove the incorrect checks for `owner != FRAME_CLEARED` as well.

* gh-121676: Raise a ``DeprecationWarning`` if the Python implementation of ↵Kirill Podoprigora2025-01-015-5/+47
| | | | | | | | | | | | | | | | | | ``functools.reduce`` is called with `function` or `sequence` as a keyword args (#121677) Python implementation of `functools` allows calling `reduce` with `function` or `sequence` as keyword args. This doesn't match behavior of our C accelerator and our documentation for `functools.reduce` states that `function`and `sequence` are positional-only arguments. Now calling a Python implementation of `functools.reduce` with `function` or `sequence` as keyword args would raise a `DeprecationWarning` and is planned to be prohibited in Python 3.16.
