Modifies the test helper that counts the list of open file descriptors to use
the optimised ``/dev/fd`` approach on all Apple platforms, not just macOS. This
avoids crashes caused by guarded file descriptors.
Fix: Prevent crash in ctypes.CField when byte_size does not match type size (gh-132470)
When creating a ctypes.CField with an incorrect byte_size (e.g., using `byte_size=2` for `ctypes.c_byte`), the code would previously abort due to the failed assertion `byte_size == info->size`.
This commit replaces the assertion with a proper error handling mechanism that raises a `ValueError` when `byte_size` does not match the expected type size. This prevents the crash and provides a more informative error message to the us

This also reverts loghelper() change in 75f59bb629 for integer
input. The error message shouldn't include argument value here.

Commit `0e9c364f` introduced the `_handle` field on instances of
`threading.Thread`. Unfortunately it's fairly common for subclasses
of `threading.Thread` to define a `_handle()` method, which is shadowed
by the new field.

Improve the error message with a suggestion when an object supporting the synchronous
(resp. asynchronous) context manager protocol is entered using `async with` (resp. `with`)
instead of `with` (resp. `async with`).
This is an option that allows the user to specify, which selected tests should
execute first, even if the order is otherwise randomized. This is particularly
useful for tests that run the longest.
Fixed an assertion error (so, it could be reproduced only in builds with assertions enabled)
for `exec` when the `source` argument is a string and the `closure` argument is not `None`.

This ensures that if we jump through some hoops to make sure something is imported
lazily, we don't regress on importing it.
I recently already accidentally made typing import warnings and annotationlib eagerly.

When the `showwarning()` function is replaced, make sure to restore
it after the test finishes. Add a timeout for `Barrier()` so we
don't hang for a long time if something goes wrong.
I started with just moving ForwardRefTests to test_annotationlib,
but found that it contained a number of tests for no_type_check, which
I moved to a new class in test_typing, as well as a number of tests that
are more appropriately classified as tests for get_type_hints().
One test, test_forward_equality_namespace(), was somewhat accidentally
depending on a global class A in test_typing. I added a class A in the
annotationlib tests instead.
Also add a useful comment in annotationlib.
Previously only an integer packed in a tuple was accepted, while
getsockname() could return a raw integer.
Now the result of getsockname() is always acceptable as an address.
In `_is_local_authority()`, return early if the authority matches the
machine hostname from `socket.gethostname()`, rather than resolving the
names and matching IP addresses.
Now all protocols always accept the Bluetooth address as string and
getsockname() always returns the Bluetooth address as string.
* BTPROTO_SCO now accepts not only bytes, but str.
* BTPROTO_SCO now checks address for embedded null.
* On *BSD, BTPROTO_HCI now accepts str instead of bytes.
* On FreeBSD, getsockname() for BTPROTO_HCI now returns str instead of bytes.
* On NetBSD and DragonFly BDS, BTPROTO_HCI now checks address for embedded null.
Add optional *add_scheme* argument to `urllib.request.pathname2url()`; when
set to true, a complete URL is returned. Likewise add optional
*require_scheme* argument to `url2pathname()`; when set to true, a complete
URL is accepted.

Add extra audit hooks to catch C function calling from ctypes,
reading/writing files through readline and executing external
programs through _posixsubprocess.
* Make audit-tests for open pass when readline.append_history_file is unavailable
* Less direct testing of _posixsubprocess for audit hooks
* Also remove the audit hook from call_cdeclfunction now that _ctypes_callproc does it instead.
* reword the NEWS entry.
* mention readline in NEWS
* add versionchanged markers
* fix audit_events.rst versionadded
* doc lint

* Also add support for cid and bdaddr_type in the BTPROTO_L2CAP address on FreeBSD.
* Return cid in getsockname() for BTPROTO_L2CAP if it is not zero.
* Fix a compiler warning on FreeBSD.
- Correctly test missing `digestmod` and `digest` parameters.
- Test when chunks of length > 2048 are passed to `update()`.
- Test one-shot HMAC-BLAKE2.
In `urllib.request.url2pathname()`, if the authority resolves to the
current host, discard it. If an authority is present but resolves somewhere
else, then on Windows we return a UNC path (as before), and on other
platforms we raise `URLError`.
Affects `pathlib.Path.from_uri()` in the same way.

Make `warnings.catch_warnings()` use a context variable for holding
the warning filtering state if the `sys.flags.context_aware_warnings`
flag is set to true. This makes using the context manager thread-safe in
multi-threaded programs.
Add the `sys.flags.thread_inherit_context` flag. If true, starting a new
thread with `threading.Thread` will use a copy of the context
from the caller of `Thread.start()`.
Both these flags are set to true by default for the free-threaded build
and false for the default build.
Move the Python implementation of warnings.py into _py_warnings.py.
Make _contextvars a builtin module.

* Always quote strings with non-ASCII characters.
* Allow some non-separator and non-control characters (like "." or "-")
be unquoted.
* Always quote strings that end with "\n".
* Use the fullmatch() method for clarity and optimization.
Non-tuple sequences are deprecated as argument for the "(items)" format unit
in PyArg_ParseTuple() and other argument parsing functions if items contains
format units which store borrowed buffer or reference (e.g. "s" and "O").
str and bytearray are no longer accepted as valid sequences.
Adding aliases for Thai language support. The current code page is an implementation of the windows code page.
This will alias '874', 'ms874', and 'windows_874' to cp874, adding Thai language support for those users.

* Add _PYTHON_SUBPROCESS_USE_POSIX_SPAWN environment knob
Add support for disabling the use of `posix_spawn` via a variable in
the process environment.
While it was previously possible to toggle this by modifying the value
of `subprocess._USE_POSIX_SPAWN`, this required either patching CPython
or modifying it within the interpreter instance which is not always
possible, such as when running applications or scripts not under a
user's control.

The `http.server` module now supports serving over HTTPS using the `http.server.HTTPSServer` class.
This functionality is also exposed by the command-line interface (`python -m http.server`) through the
`--tls-cert`, `--tls-key` and `--tls-password-file` options.
