This was added in 3.15; let's use a real sentinel instead of an ad-hoc list object.

gh-129011: Update docs for Raw I/O read, readinto, and write (GH-135328)
Update `RawIOBase` and `FileIO` documentation to match implementation
behavior around `.read`, `.readinto`, `.readall` and `.write`.
In particular:
- They may make more than one system call (PEP-475)
- Add warnings if `.write()` requires a wrapping retry loop (see: gh-126606)
- "Raw I/O" `.write`` may not write all bytes
- `buffering=0` example results in a "Raw I/O"

The current documentation says:
>
> METH_FASTCALL
> Part of the Stable ABI since version 3.7.
>
> [...]
>
> Added in version 3.7.
>
> Changed in version 3.10: METH_FASTCALL is now part of the stable ABI.
so is contradictory about when it was added to the Stable ABI. Looking at the header it seems like 3.10 is right.

gh-150436: Skip subprocess test on STATUS_DLL_INIT_FAILED (GH-150704)
If a subprocess spawned with CREATE_NEW_CONSOLE creation flag fails
with STATUS_DLL_INIT_FAILED return code, skip the test. It's likely a
memory allocation failure in the desktop heap memory which caused the
DLL init failure.

gh-150723: Fix perf jitdump files on macOS (GH-150728)
The perf jitdump format defines the thread id field of the JR_CODE_LOAD
record as a 32-bit value, but on macOS it was declared as a uint64_t
(since pthread_threadid_np() returns a uint64_t). Those extra 8 bytes
plus alignment padding shifted every following field, so parsers reading
the file by the spec misread code_size as the code address and failed to
resolve any Python frames.
Declare thread_id as uint32_t on all platforms and truncate the macOS
thread id when writing the record. The value is only informational.
Symbols are resolved by address, and not thread ids so truncation is
safe here.
* Use mach_absolute_time for macOS jitdump timestamps
On macOS the jitdump file is consumed by profilers such as samply, which
timestamp their samples using mach_absolute_time(). The jitdump events were
stamped with clock_gettime(CLOCK_MONOTONIC), a different clock domain that
keeps advancing while the system is asleep, so the JIT code mappings could be
off by days relative to the samples and no Python frame would resolve. Stamp
jitdump events with mach_absolute_time() on macOS so they share the sampler's
clock domain. Linux continues to use CLOCK_MONOTONIC to stay aligned with perf.
Exercise the -Xperf_jit (jitdump) backend through samply and assert that
Python frames resolve, exercising the binary jitdump path end to end.
Skipped when samply is not installed.

gh-150319: Replace all documentation which says "See PEP 585" (GH-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
