was zero, bypassing validation performed for non-empty slices.

gh-150319: Replace all documentation which says "See PEP 585" (#150325)
* Replace all documentation which says "See PEP 585"
The following classes in the stdlib get simple updates:
- array.array
- asyncio.Future
- asyncio.Task
- collections.defaultdict
- collections.deque
- contextvars.ContextVar
- contextvars.Token
- ctypes.Array
- os.DirEntry
- re.Match
- re.Pattern
- string.templatelib.Interpolation
- string.templatelib.Template
- types.MappingProxyType
- queue.SimpleQueue
- weakref.ref
The following classes are documented publicly as functions, and are
therefore updated internally (`__class_getitem__.__doc__`) but not in the
public docs:
- functools.partial
- itertools.chain
The following builtin types have updates to `__class_getitem__.__doc__`
but not to any documentation pages:
- BaseExceptionGroup
- coroutines (from generators)
- dict
- enumerate
- frozendict
- frozenset
- generators (and async generators)
- list
- memoryview
- set
- slice
- tuple
Special cases:
- union objects are now documented as "supporting class-level []",
rather than anything to do with generics.
- Templates might be generic over a single type (union, in theory) or
over a TypeVarTuple. As this is not currently fully settled, it is
marked with a comment and a mild hint that it is a single type is used
(namely, "type" is singular rather than "types", plural)
* Apply suggestions from code review
* Correct several class getitem docs
And expand the text for tuples.
* Add notes on generic typing of builtins
* Fix typo in tuple.__class_getitem__ docstring
* Typo fix: malformed refs
Fix `generic` links which weren't marked as `:ref:`.
* Strike unnecessary docs on generic-ness
* Apply suggestions from code review
These are applied at both the originally indicated locations and in the
corresponding docstring definitions.
* Update Doc/library/re.rst
* Update Objects/enumobject.c
* Remove tuple generic doc in 'stdtypes' page
This is covered in more detail in the cross-linked typing documentation.
The other copy of this documentation -- in the docstring for
`tuple.__class_getitem__` -- is left in place.
* Fix whitespace around new doc of generics
Per review, do not introduce or remove whitespace such that section
breaks are altered by the introduction of doc on various generic types.
In most cases, this is a removal of an extra line.
In one case (Arrays), it is the reintroduction of a line.
Additionally, two other minor fixes are included:
- incorrect indent on 'defaultdicts'
- make `mappingproxy.__class_getitem__.__doc__` consistent with other
mapping type generic docs
* Move placement of memoryview generic note
Previous placement was at the end of the main docstring, which is
consistent with other types but places it after a section on various
methods (which makes it read somewhat inconsistently). Moving it up
helps resolve.
* Ensure sphinxdoc does not start sentences lowercase
Lowercase class names at the start of sentences are marked out with the
`class` role. In the case of `deque`, documentation already refers to
these as `Deques`, so this form is preferred.
* Apply suggestions from code review
* Fix line endings and wrap more tightly
Line endings fixed by pre-commit ; also re-wrapped the MappingProxyType
text which was too long.
* Use 'ContextVars' style in sphinx doc

Replace the insertion sort used for canonical ordering of combining
characters with a hybrid approach: insertion sort for short runs (< 20)
and counting sort for longer runs, reducing worst-case complexity from
O(n^2) to O(n). This prevents denial of service via crafted Unicode
strings with many combining characters in alternating CCC order.

gh-142831: Fix use-after-free in json encoder during re-entrant mutation (gh-142851)
User callbacks invoked during JSON encoding (e.g. the `default` callback or
a custom string encoder) can mutate or clear the dict or sequence being
encoded, invalidating borrowed references to items, keys, and values. Hold
strong references unconditionally while iterating.

`faulthandler_traverse` visits Python objects owned by `_PyRuntime`, not
by the module instance. With multi-phase init allowing multiple module
instances, each instance's GC traversal decrements `gc_refs` on the same
runtime-owned objects, driving it negative when two instances are
collected simultaneously.

gh-149707: Fix compiler warning in _ctypes_test on strchr() (#149791)
Change my_strchr() return type to "const char*" (add "const").
Fix the compiler warning:
Modules/_ctypes/_ctypes_test.c: In function 'my_strchr':
Modules/_ctypes/_ctypes_test.c:451:12: warning: return discards
'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
451 | return strchr(s, c);
| ^~~~~~
When using C23, strchr(text, ch) return type is "const char*" if text
type is "const char*".

gh-145105: Fix crash in csv.reader with re-entrant iterator (GH-145106)
When a custom iterator calls next() on the same csv.reader from
within __next__, the inner iteration sets self->fields to NULL.
The outer iteration then crashes in parse_save_field() by passing
NULL to PyList_Append.
Add a guard after PyIter_Next() to detect that fields was set to
NULL by a re-entrant call, and raise csv.Error instead of crashing.

The long_from_string_base() might return a small integer, when the
_pylong.py is used to do conversion. Hence, we must be careful here to
not smash it "small int" bit by using the _PyLong_FlipSign().

Base64 decoder (see binascii.a2b_base64(), base64.b64decode(), etc)
no longer ignores excess data after the first padded quad in non-strict

pad character, "=", if it is present before the end of the encoded data.
