The r in `rglob` stands for "recursively", so use the word in the description. Also, glob and rglob can usefully be mentioned as the pathlib equivalent of os.walk.

Support for bytes broke sometime between Python 3.2 and 3.6 and has been broken ever since. Trying to bring back supports is surprisingly difficult in the face of -b and checking for keys in sys.path_importer_cache. Since the support was broken for so long, trying to overcome the difficulty of bringing back the support has been deemed not worth it.

* Add additional pointers to pathlib's mapping to os.path functions
os.path.splitext has a somewhat quirky signature since it mixes the path and filename components but I wanted the documentation to mention `PurePath.stem` as the natural counterpart to `PurePath.suffix` for the common use of `os.path.splitext` to turn "file.py" into "file" and "py".
Technically this could have some discussion of how to handle the parent directory hierarchy but that seems a bit out of keeping with the spirit of this table so I omitted mentioning `PurePath.parents` here.
* Update Doc/library/pathlib.rst

* gh-93883: elide traceback indicators when possible
Elide traceback column indicators when the entire line of the
frame is implicated. This reduces traceback length and draws
even more attention to the remaining (very relevant) indicators.
Example:
```
Traceback (most recent call last):
File "query.py", line 99, in <module>
bar()
File "query.py", line 66, in bar
foo()
File "query.py", line 37, in foo
magic_arithmetic('foo')
File "query.py", line 18, in magic_arithmetic
return add_counts(x) / 25
^^^^^^^^^^^^^
File "query.py", line 24, in add_counts
return 25 + query_user(user1) + query_user(user2)
^^^^^^^^^^^^^^^^^
File "query.py", line 32, in query_user
return 1 + query_count(db, response['a']['b']['c']['user'], retry=True)
~~~~~~~~~~~~~~~~~~^^^^^
TypeError: 'NoneType' object is not subscriptable
```
Rather than going out of our way to provide indicator coverage
in every traceback test suite, the indicator test suite should
be responible for sufficient coverage (e.g. by adding a basic
exception group test to ensure that margin strings are covered).
Deprecate typing.Hashable/Sized. Use the collections.abc counterparts directly instead.
To be consistent with PEP 585, deprecated aliases will not raise any DeprecationWarning.
Remove the ssl.wrap_socket() function, deprecated in Python 3.7:
instead, create a ssl.SSLContext object and call its
sl.SSLContext.wrap_socket() method. Any package that still uses
ssl.wrap_socket() is broken and insecure. The function neither sends
a SNI TLS extension nor validates server hostname. Code is subject to
CWE-295 : Improper Certificate Validation.
zipimport: Remove find_loader() and find_module() methods, deprecated
in Python 3.10: use the find_spec() method instead. See PEP 451 for
the rationale.
xml.etree: Remove the ElementTree.Element.copy() method of the pure
Python implementation, deprecated in Python 3.10, use the copy.copy()
function instead. The C implementation of xml.etree has no copy()
method, only a __copy__() method.
Adds `ctypes.c_time_t` to represent the C `time_t` type accurately as its size varies.

In the queue documentation, the code snippet shows the import to be not PEP 8 compliant.
Since people typically copy-paste from such code samples, I think it's important to show best-practices here.
Once the task group is shutting down, it should not be possible to create a new task.
Here "shutting down" means `self._aborting` is set, indicating that at least one task
has failed and we have cancelled all others.

Remove dead code related to ssl.PROTOCOL_SSLv2. ssl.PROTOCOL_SSLv2
was already removed in Python 3.10.
In test_ssl, @requires_tls_version('SSLv2') always returned False.
Extract of the removed code: "OpenSSL has removed support for SSLv2".
Remove the pure Python implementation of hashlib.pbkdf2_hmac(),
deprecated in Python 3.10. Python 3.10 and newer requires OpenSSL
1.1.1 or newer (PEP 644), this OpenSSL version provides a C
implementation of pbkdf2_hmac() which is faster.
Remove the locale.format() function, deprecated in Python
3.7: use locale.format_string() instead.
Remove TestFormatPatternArg test case: it is irrelevant for
locale.format_string() which accepts complex formats.
`tarfile` already accepts a compressionlevel argument for creating
files. This patch adds the same for stream-based tarfile usage.
The default is 9, the value that was previously hard-coded.
gzip: Remove the filename attribute of gzip.GzipFile,
deprecated since Python 2.6, use the name attribute instead. In write
mode, the filename attribute added '.gz' file extension if it was not
present.
Remove io.OpenWrapper and _pyio.OpenWrapper, deprecated in Python
3.10: just use :func:`open` instead. The open() (io.open()) function
is a built-in function. Since Python 3.10, _pyio.open() is also a
static method.
When used with plain Enum, auto() returns the last numeric value assigned, skipping any incompatible member values (such as strings); starting in 3.13 the default auto() for plain Enums will require all the values to be of compatible types, and will return a new value that is 1 higher than any existing value.

Move the follow functions and type from frameobject.h to pyframe.h,
so the standard <Python.h> provide frame getter functions:
* PyFrame_Check()
* PyFrame_GetBack()
* PyFrame_GetBuiltins()
* PyFrame_GetGenerator()
* PyFrame_GetGlobals()
* PyFrame_GetLasti()
* PyFrame_GetLocals()
* PyFrame_Type
Remove #include "frameobject.h" from many C files. It's no longer

Per @brettcannon 's [suggestions on the Discourse thread](https://discuss.python.org/t/pep-594-take-2-removing-dead-batteries-from-the-standard-library/13508/51), discussed in #92611 and as a followup to PR #92612 , this PR add additional specific per-function replacement information for the utility functions in the `cgi` module deprecated by PEP 594 (PEP-594).
@brettcannon , should this be backported (without the `deprecated-removed` , which I would update it accordingly and re-add in my other PR adding that to the others for 3.11+), or just go in 3.11+?
Deprecate global configuration variable like
Py_IgnoreEnvironmentFlag: the Py_InitializeFromConfig() API should be
instead.
Fix declaration of Py_GETENV(): use PyAPI_FUNC(), not PyAPI_DATA().
Corrected targets for the following audit-events:
- sqlite3.enable_load_extension => sqlite3.Connection.enable_load_extension
- sqlite3.load_extension => sqlite3.Connection.load_extension
Align the docs for the following methods with the actual implementation:
- sqlite3.complete_statement()
- sqlite3.Connection.create_function()
- sqlite3.Connection.create_aggregate()
- sqlite3.Connection.set_progress_handler()
Documentation for `pathlib` says:
> Spurious slashes and single dots are collapsed, but double dots ('..') are not, since this would change the meaning of a path in the face of symbolic links:
However, it omits that initial double slashes also aren't collapsed.
Later, in documentation of `PurePath.drive`, `PurePath.root`, and `PurePath.name` it mentions UNC but:
- this abbreviation says nothing to a person who is unaware about existence of UNC (Wikipedia doesn't help either by [giving a disambiguation page](https://en.wikipedia.org/wiki/UNC))
- it shows up only if a person needs to use a specific property or decides to fully learn what the module provides.
For context, see the BPO entry.
This checks the bases of of a type created using the FromSpec
API to inherit the bases metaclasses. The metaclass's alloc
function will be called as is done in `tp_new` for classes
created in Python.

These are currently broken as they refer to :meth:`Path.relative_to` rather than :meth:`PurePath.relative_to`, and `relative_to` is a method on `PurePath`.
This is purely for SEO as this is the actual generic name for this kind of method and it currently does not appear in a Google search for "python constant time compare". Not creating an issue or setting this up for backports as its trivial (I think) and not a functional change.
* bpo-42272: improve message/module warning filter docs
"The Warnings Filter" section of the warnings module documentation
describes the message and module filters as "a string containing a
regular expression". While that is true when they are arguments to the
filterwarnings function, it is not true when they appear in -W or
$PYTHONWARNINGS where they are matched literally (after stripping any
starting/ending whitespace). Update the documentation to note when they
are matched literally. Also clarify that module matches the
"fully-qualified module name", rather than "module name" which is
ambiguous.

* bpo-42272: remove bad submodule warning filter doc
The `error:::mymodule[.*]` example in the "Describing Warning Filters"
section of the warnings module documentation does not behave as the
comment describes. Since the module portion of the filter string is
interpreted literally, it would match a module with a fully-qualified
name that is literally `mymodule[.*]`.
Unfortunately, there is not a way to match '"module" and any subpackages
of "mymodule"' as documented, since the module part of a filter string
is matched literally. Instead, update the filter and comment to match
only "mymodule".

This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing:
* the configure option
* the macro
* the code enabled by the macro
This is a rework of #5774 on current main. I was a bit more
conservative in making changes than the original PR.
See @csabella's comments on issue #77024 and the discussion
on #5774 for explanations of several of the changes.

Added a new stable API function ``PyType_FromMetaclass``, which mirrors
the behavior of ``PyType_FromModuleAndSpec`` except that it takes an
additional metaclass argument. This is, e.g., useful for language
binding tools that need to store additional information in the type
object.
Python now always use the ``%zu`` and ``%zd`` printf formats to
format a size_t or Py_ssize_t number. Building Python 3.12 requires a
C11 compiler, so these printf formats are now always supported.
* PyObject_Print() and _PyObject_Dump() now use the printf %zd format
to display an object reference count.
* Update PY_FORMAT_SIZE_T comment.
* Remove outdated notes about the %zd format in PyBytes_FromFormat()
and PyUnicode_FromFormat() documentations.
* configure no longer checks for the %zd format and no longer defines
PY_FORMAT_SIZE_T macro in pyconfig.h.
* pymacconfig.h no longer undefines PY_FORMAT_SIZE_T: macOS 10.4 is
no longer supported. Python 3.12 now requires macOS 10.6 (Snow
Leopard) or newer.
