This introduces a new decorator `@inspect.markcoroutinefunction`,
which, applied to a sync function, makes it appear async to
`inspect.iscoroutinefunction()`.
gh-100176: Remove redundant compat code for Python 3.2 and older
Python 3.2 has been EOL since 2016-02-20 and 2.7 since 2020-01-01, so we
can remove this old compatibility check and unindent the old else-block.
Also, in the unindented block, replace a .format() call with an f-string.
Plus similar changes in the documentation.
Example needed to be indented. Was trying to call a context manger `pr` (from ` with cProfile.Profile() as pr:`) wot perform ` pr.print_stats()` once it had already exited.

A few TCP socket options have been added to the Linux kernel these last
few years.
This commit adds all the ones available in Linux 6.0:
https://elixir.bootlin.com/linux/v6.0/source/include/uapi/linux/tcp.h#L91
While at it, the TCP_FASTOPEN option has been moved lower in the list
just to keep the same order as in tcp.h to ease future synchronisations.

asyncio.get_event_loop() now always return either running event loop or
the result of get_event_loop_policy().get_event_loop() call. The latter
should now raise an RuntimeError if no current event loop was set
instead of creating and setting a new event loop.
It affects also a number of asyncio functions and constructors which
call get_event_loop() implicitly: ensure_future(), shield(), gather(),
etc.
DeprecationWarning is no longer emitted if there is no running event loop but
the current event loop was set.

Replace control characters in http.server.BaseHTTPRequestHandler.log_message with an escaped \xHH sequence to avoid causing problems for the terminal the output is printed to.
* Change documentation for sys.float_info.rounds
Change the documentation for sys.float_info.rounds to remove
references to C99 section 5.2.4.2.2 and instead place the
available values inline.
* Correction to previous documentation change
Newlines were not preserved in generated HTML on previous
commit. I have changes the list to a comma-separated list
of values and their meanings.
* Clarify source for value of FLT_ROUNDS
Clarify the source of the FLT_ROUNDS value and
change 'floating-point addition' to 'floating-point
arithmetic' to indicate that the rounding mode
applies to all arithmetic operations.
* nail down a couple examples to have more predictable output
* update a number of things, but this is really just a stash...
* added an applications section to describe typical uses for native and machine-independent formats
* make sure all format strings use a format prefix character
* responding to comments from @gpshead. Not likely finished yet.
* This got more involved than I expected...
* respond to several PR comments
* a lot of wordsmithing
* try and be more consistent in use of ``x`` vs ``'x'``
* expand examples a bit
* update the "see also" to be more up-to-date
* original examples relied on import * so present all examples as if
* reformat based on @gpshead comment (missed before)
* responding to comments
* missed this
* one more suggested edit
* wordsmithing
On some platforms, and in particular macOS/arm64, the calling
convention for variadic arguments is different from the regular
calling convention. Add a section to the documentation to document
this.
os.remove can raise PermissionError instead of IsADirectoryError,
when the object to be removed is a directory (in particular on
macOS).
This reverts a change done in #14262.
# DOC: Improvements in library/stdtypes
This PR does the following:
1. Replaces :meth: by :func: around repr function
2. Adds links to Unicode Standard site
3. Makes explicit "when" you can call the `iskeyword` function. The previous text could cause confusion to readers, especially those with English as a second language. The reader could understand that the `isidentifier` method calls the `iskeyword` function. Now, it is explicit that the dev can do it.
4. Replaces a URL with an inline link.

Improves the docstring on signal.strsignal to make it explain when it returns a message, None, or when it raises ValueError.

* fix auto() failure during multiple assignment
i.e. `ONE = auto(), 'text'` will now have `ONE' with the value of `(1,
'text')`. Before it would have been `(<an auto instance>, 'text')`
A backslash-character pair that is not a valid escape sequence now
generates a SyntaxWarning, instead of DeprecationWarning. For
example, re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an
invalid escape sequence), use raw strings for regular expression:
re.compile(r"\d+\.\d+"). In a future Python version, SyntaxError will
eventually be raised, instead of SyntaxWarning.
Octal escapes with value larger than 0o377 (ex: "\477"), deprecated
in Python 3.11, now produce a SyntaxWarning, instead of
DeprecationWarning. In a future Python version they will be
eventually a SyntaxError.
codecs.escape_decode() and codecs.unicode_escape_decode() are left
unchanged: they still emit DeprecationWarning.
* The parser only emits SyntaxWarning for Python 3.12 (feature
version), and still emits DeprecationWarning on older Python
versions.
* Fix SyntaxWarning by using raw strings in Tools/c-analyzer/ and
wasm_build.py.
The function has been removed. In the ssl documentation, replace
references to the ssl.wrap_socket() function with references to the
ssl.SSLContext.wrap_socket() method.

In very rare circumstances the JUMP opcode could be confused with the
argument of the opcode in the "then" part which doesn't end with the
JUMP opcode. This led to incorrect detection of the final JUMP opcode
and incorrect calculation of the size of the subexpression.
NOTE: Changed return value of functions _validate_inner() and
_validate_charset() in Modules/_sre/sre.c. Now they return 0 on success,
-1 on failure, and 1 if the last op is JUMP (which usually is a failure).
Previously they returned 1 on success and 0 on failure.
By default, :meth:`pathlib.PurePath.relative_to` doesn't deal with paths that are not a direct prefix of the other, raising an exception in that instance. This change adds a *walk_up* parameter that can be set to allow for using ``..`` to calculate the relative path.
example:
```
>>> p = PurePosixPath('/etc/passwd')
>>> p.relative_to('/etc')
PurePosixPath('passwd')
>>> p.relative_to('/usr')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pathlib.py", line 940, in relative_to
raise ValueError(error_message.format(str(self), str(formatted)))
ValueError: '/etc/passwd' does not start with '/usr'
>>> p.relative_to('/usr', strict=False)
PurePosixPath('../etc/passwd')
```

Change FOR_ITER to have the same stack effect regardless of whether it branches or not.
Performance is unchanged as FOR_ITER (and specialized forms jump over the cleanup code).

This is the next step for deprecating child watchers.
Until we've removed the API completely we have to use it, so this PR is mostly suppressing a lot of warnings when using the API internally.
Once the child watcher API is totally removed, the two child watcher implementations we actually use and need (Pidfd and Thread) will be turned into internal helpers.
