As it says in its documentation, walk_stack was meant to just
follow `f.f_back` like other functions in the traceback module.
Instead it was previously doing `f.f_back.f_back` and then this
changed to `f_back.f_back.f_back.f_back' in Python 3.11 breaking
its behavior for external users.
This happened because the walk_stack function never really had
any good direct tests and its only consumer in the traceback module was
`extract_stack` which passed the result into `StackSummary.extract`.
As a generator, it was previously capturing the state of the stack
when it was first iterated over, rather than the stack when `walk_stack`
was called. Meaning when called inside the two method deep
`extract` and `extract_stack` calls, two `f_back`s were needed.
When 3.11 modified the sequence of calls in `extract`, two more
`f_back`s were needed to make the tests happy.
This changes the generator to capture the stack when `walk_stack` is
called, rather than when it is first iterated over. Since this is
technically a breaking change in behavior, there is a versionchanged
to the documentation. In practice, this is unlikely to break anyone,
you would have been needing to store the result of `walk_stack` and
expecting it to change.
Updates error messages in datetime and makes them consistent between Python and C.

The call to `PySequence_List()` could temporarily unlock and relock the
set, allowing the items to be cleared and return the incorrect
notation `{}` for a empty set (it should be `set()`).

Fix a few thread-safety bugs to enable test_opcache when run with TSAN:
* Use relaxed atomics when clearing `ht->_spec_cache.getitem`
(gh-115999)
* Add temporary suppression for type slot modifications (gh-127266)
* Use atomic load when reading `*dictptr`
GH-127712: Fix `secure` argument of `logging.handlers.SMTPHandler`
Python 3.12 removed support for the `keyfile` and `certfile` parameters
in `smtplib.SMTP.starttls()`, requiring a `ssl.SSLContext` instead.
`SMTPHandler` now creates a context from the `secure` tuple and passes
that to `starttls`.
In case gcc is not available, the test will fail with FileNotFoundError.
So catch the exception to skip the test correctly.

Move pathlib's private `CopyReader`, `LocalCopyReader`, `CopyWriter` and
`LocalCopyWriter` classes into `pathlib._os`, where they can live alongside
the low-level copying functions (`copyfileobj()` etc) and high-level path
querying interface (`PathInfo`).
This sets the stage for merging `LocalCopyReader` into `PathInfo`.
No change of behaviour; just moving some code around.
In `help.copy_strip`, only copy the text `<section>`. In `help.HelpParser.handle_starttag` and elsewhere, remove code to skip the no longer present html. Add a reminder at the top of idle.rst to run copy_strip after changes.

* gh-128657: Run test_hashlib with `--parallel-threads`
This catches the race in `py_digest_by_name` that is fixed separately
in gh-128886.
* Adjust assertion order
Also extend the 'idlelib' section header. These additions affect both the displayed idle.html file and the contents.html file displayed by clicking the Complete table of contents link on the main docs.python.org page.

Add function to list the currently loaded libraries to ctypes.util
The dllist() function calls platform-specific APIs in order to
list the runtime libraries loaded by Python and any imported modules.
On unsupported platforms the function may be missing.

In the private pathlib ABCs, make `ReadablePath.glob('')` yield a path with
a trailing slash (if it yields anything at all). As a result, `glob()`
works similarly to `joinpath()` when given a non-magic pattern.
In the globbing implementation, we preemptively add trailing slashes to
intermediate paths if there are pattern parts remaining; this removes the
need to check for existing trailing slashes (in the removed `add_slash()`
method) at subsequent steps.
Add `pathlib.Path.info` attribute, which stores an object implementing the `pathlib.types.PathInfo` protocol (also new). The object supports querying the file type and internally caching `os.stat()` results. Path objects generated by `Path.iterdir()` are initialised with status information from `os.DirEntry` objects, which is gleaned from scanning the parent directory.
The `PathInfo` protocol has four methods: `exists()`, `is_dir()`, `is_file()` and `is_symlink()`.
