Less specific number wording (as there is no one right number - the old 100k is too big for some applications and woefully small for others). We now link to NIST SP 800-132 to tell people what to read in there on how to decide for their application.

Revert "bpo-45162: Remove many old deprecated unittest features (GH-28268)"
This reverts commit b0a6ede3d0.
We're deferring this change until 3.12 while upstream projects that use
the legacy assertion method names are fixed. See the issue for links
to the discussion. Many upstream projects now have issues and PRs
filed.
In the File menu, 'Close' and 'Exit' are now 'Close Window' (the current
one) and 'Exit' is now 'Exit IDLE' (by closing all windows).
In Shell, 'quit()' and 'exit()' mean 'close Shell'.
If there are no other windows, this also exits IDLE.
When configuring the logging stack, accept already built filters (or
just callables) in the filters array of loggers and handlers.
This facilitates passing quick callables as filters.

A small change to the documentation of datetime module , in the format codes section of stftime and strptime. Changed the description of format code '%W' from 'as a decimal number' to 'a zero padded decimal number' so it's in line with the example having leading zeros. Similar to the format code '%U' above.

The documentation on ``GenericAlias`` objects implies at multiple points that
only container classes can define ``__class_getitem__``. This is misleading.
This PR proposes a rewrite of the documentation to clarify that non-container
classes can define ``__class_getitem__``, and to clarify what it means when a
non-container class is parameterized.
See also: initial discussion of issues with this piece of documentation in
GH-29308, and previous BPO issue [42280](https://bugs.python.org/issue42280).
Also improved references in glossary and typing docs. Fixed some links.

- skip doctest that changes depending on target system
- skip doctest that only fails on CI
- substitute in values that change depending on target system
Undo rejected PEP-663 changes:
- restore `repr()` to its 3.10 status
- restore `str()` to its 3.10 status
New changes:
- `IntEnum` and `IntFlag` now leave `__str__` as the original `int.__str__` so that str() and format() return the same result
- zero-valued flags without a name have a slightly changed repr(), e.g. `repr(Color(0)) == '<Color: 0>'`
- update `dir()` for mixed-in types to return all the methods and attributes of the mixed-in type
- added `_numeric_repr_` to `Flag` to control display of unnamed values
- enums without doc strings have a more comprehensive doc string added
- `ReprEnum` added -- inheriting from this makes it so only `__repr__` is replaced, not `__str__` nor `__format__`; `IntEnum`, `IntFlag`, and `StrEnum` all inherit from `ReprEnum`
Add `string.Template.get_identifiers()` method that returns the identifiers within the template. By default, raises an error if it encounters an invalid identifier (like `substitute()`). The keyword-only argument `raise_on_invalid` can be set to `False` to ignore invalid identifiers (like `safe_substitute()`).

`@dataclass` in 3.10 prohibits using list, dict, or set as default values. It does this to avoid the mutable default problem. This test is both too strict, and not strict enough. Too strict, because some immutable subclasses should be safe, and not strict enough, because other mutable types should be prohibited. With this change applied, `@dataclass` now uses unhashability as a proxy for mutability: if objects aren't hashable, they're assumed to be mutable.
Modify the ``EnumType.__dir__()`` and ``Enum.__dir__()`` to ensure
that user-defined methods and methods inherited from mixin classes always
show up in the output of `help()`. This change also makes it easier for
IDEs to provide auto-completion.
Document the `port` parameter to `loop.create_server` in `asyncio`. In
particular, note that if `host` resolves to multiple network interfaces,
passing in `port=0` will result in a different random unused port being
used for each interface.

It is now considered a historical accident that e.g. `for` loops and the `iter()` built-in function do not require the iterators they work with to define `__iter__`, only `__next__`.
The documentation explaining Python's data model does not adequately explain
the differences between ``__getitem__`` and ``__class_getitem__``, nor does it
explain when each is called. There is an attempt at explaining
``__class_getitem__`` in the documentation for ``GenericAlias`` objects, but
this does not give sufficient clarity into how the method works. Moreover, it
is the wrong place for that information to be found; the explanation of
``__class_getitem__`` should be in the documentation explaining the data model.

* bpo-45772: socket.socket should be a class instead of a function
Currently `socket.socket` is documented as a function, but it is really
a class (and thus has function-like usage to construct an object). This
correction would ensure that Python projects that are interlinking
Python's documentation can properly locate `socket.socket` as a type.
This gains 10% or more in startup time for `python -c pass` on UNIX-ish systems.
The Makefile.pre.in generating code builds on Eric's work for bpo-45020, but the .c file generator is new.
Windows version TBD.
``typing.Tuple`` has been deprecated since Python 3.9, so it makes no sense to mention it so prominently in the documentation for the ``typing`` module.
Specify that SSLContext.set_default_verify_paths is called on ALL systems.
The code of SSLContext.load_default_certs was changed in bpo-22449 to do this,
this fix corrects the documentation to match that change.
The link broke for Python 3.10 since importlib.metadata was made from a module into a package
I think this is trivial enough to not need a bpo issue.

Currently custom modules (the array set on PyImport_FrozenModules) replace all the frozen stdlib modules. That can be problematic and is unlikely to be what the user wants. This change treats the custom frozen modules as additions instead. They take precedence over all other frozen modules except for those needed to bootstrap the import system. If the "code" field of an entry in the custom array is NULL then that frozen module is treated as disabled, which allows a custom entry to disable a frozen stdlib module.
This change allows us to get rid of is_essential_frozen_module() and simplifies the logic for which frozen modules should be ignored.

The list of PEPs at the top of the documentation for the ``typing`` module has

Correctly hand various failure modes when resizing an mmap on Windows:
* Resizing a pagefile-backed mmap now creates a new mmap and copies data
* Attempting to resize when another mapping is held on the same file raises an OSError
* Attempting to resize a nametagged mmap raises an OSError if another mapping is held with the same nametag
Rename namespace package __loader__ class to be public.
Make the old name, i.e. _NamespaceLoader, an alias for the public name, for backward compatibility.
Added non parallel-safe :func:`~contextlib.chdir` context manager to change
the current working directory and then restore it on exit. Simple wrapper
around :func:`~os.chdir`.

I considered only falling back when both were 0, but that still seems
wrong, and the highly popular rich[1] library does it this way, so I
thought we should probably inherit that behavior.

This is true of all dictionaries in Python, but this one tends to
catch people off guard as they don't realize when sys.modules might
change out from underneath them as a hidden side effect of their
code. Copying it first avoids the RuntimeError. An example when
this happens in single threaded code are codecs being loaded which
are an implicit time of use import that most need not think about.
It took me longer than I expected to figure out why a random class
I dealt with didn't support weak references. I believe this addition
will make the __slots__/weakref interaction more discoverable to people
having troubles with this. (Before this patch __slots__ was not
mentioned in weakref documentation even once).
