In the tests for `pathlib.Path.walk()`, avoid using the path class under
test (`self.cls`) in test setup. Instead we use `os` functions in
`test_pathlib`, and direct manipulation of `DummyPath` internal data in
`test_pathlib_abc`.
These methods combine `_delete()` and `copy()`, but `_delete()` isn't part
of the public interface, and it's unlikely to be added until the pathlib
ABCs are made official, or perhaps even later.
* 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
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.
- 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}`
There was a data race on the utf8 field between `PyUnicode_SET_UTF8` and
`_PyUnicode_CheckConsistency`. Use the `_PyUnicode_UTF8()` accessor,
which uses an atomic load internally, to avoid the data race.
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
a53cc3f494 (GH-116687). Remove the incorrect
checks for `owner != FRAME_CLEARED` as well.
Expose error code ``XML_ERROR_NOT_STARTED`` in `xml.parsers.expat.errors` which was
introduced in Expat 2.6.4.

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.
