IPV4_RE includes a ., and the .find(".") == -1 included here is already testing to make sure there's no dot, so this part of the expression is tautological. Instead use more modern in syntax to make it clear what the check is doing here

This change is trivial so I did not open an issue.

I filed #31004 for this same change, and a bot linked linked me to some CLA instructions which tell me a bot will present me with a button in the comment. So I assume the workflow has changed and I'll get a CLA bot request on this new PR.

Hmm. I thought I saw a green "CLA signed" but upon reloading the page it's red again, and the CLA check is red. Let me know how I can sort this out and I'd be happy to sign it.

You're good on the CLA front, it seems. I added a skip-issue label, but you'll still need to add a news entry for this PR; you can do this at https://blurb-it.herokuapp.com/

This looks good to me.

I guess the only concern is whether it's useful for the IPV4_RE.search clause to be there even if it currently does nothing. But that regex doesn't seem likely to change and more importantly, the RFC 2965 wording is pretty clear:

   The term effective host name is related to host name.  If a host name
   contains no dots, the effective host name is that name with the
   string .local appended to it.  Otherwise the effective host name is
   the same as the host name.  Note that all effective host names
   contain at least one dot.

Thank you! While CPython typically does not encourage trivial changes, this clearly makes the code more readable / idiomatic and matches the RFC 2965 spec better.

Also interestingly blurbit failed for me, but I was able to push manually:

❌ Cannot create news file for GH-99588! Make sure you have access to that PR!

Seems OK; I might skip the NEWS entry since there should be no user-visible effect (unless someone monkeypatches IPv4_RE, I guess), but there's no harm in keeping it.

Going to click "update branch" in the hope it will make CI pass.

* pythongh-85267: Improvements to inspect.signature __text_signature__ handling (python#98796)

This makes a couple related changes to inspect.signature's behaviour
when parsing a signature from `__text_signature__`.

First, `inspect.signature` is documented as only raising ValueError or
TypeError. However, in some cases, we could raise RuntimeError.  This PR
changes that, thereby fixing python#83685.

(Note that the new ValueErrors in RewriteSymbolics are caught and then
reraised with a message)

Second, `inspect.signature` could randomly drop parameters that it
didn't understand (corresponding to `return None` in the `p` function).
This is the core issue in python#85267. I think this is very surprising
behaviour and it seems better to fail outright.

Third, adding this new failure broke a couple tests. To fix them (and to
e.g. allow `inspect.signature(select.epoll.register)` as in python#85267), I
add constant folding of a couple binary operations to RewriteSymbolics.

(There's some discussion of making signature expression evaluation
arbitrary powerful in python#68155. I think that's out of scope. The
additional constant folding here is pretty straightforward, useful, and
not much of a slippery slope)

Fourth, while python#85267 is incorrect about the cause of the issue, it turns
out if you had consecutive newlines in __text_signature__, you'd get
`tokenize.TokenError`.

Finally, the `if name is invalid:` code path was dead, since
`parse_name` never returned `invalid`.

* pythongh-68320, pythongh-88302 - Allow for private `pathlib.Path` subclassing (pythonGH-31691)

Users may wish to define subclasses of `pathlib.Path` to add or modify
existing methods. Before this change, attempting to instantiate a subclass
raised an exception like:

    AttributeError: type object 'PPath' has no attribute '_flavour'

Previously the `_flavour` attribute was assigned as follows:

    PurePath._flavour        = xxx not set!! xxx
    PurePosixPath._flavour   = _PosixFlavour()
    PureWindowsPath._flavour = _WindowsFlavour()

This change replaces it with a `_pathmod` attribute, set as follows:

    PurePath._pathmod        = os.path
    PurePosixPath._pathmod   = posixpath
    PureWindowsPath._pathmod = ntpath

Functionality from `_PosixFlavour` and `_WindowsFlavour` is moved into
`PurePath` as underscored-prefixed classmethods. Flavours are removed.

This improves the lives of type annotation users of `float` - which type checkers implicitly treat as `int|float` because that is what most code actually wants. Before this change a `.is_integer()` method could not be assumed to exist on things annotated as `: float` due to the method not existing on both types.

If you had a directory called index.html or index.htm within a directory, it would cause http.server to return a 404 Not Found error instead of the directory listing. This came about due to not checking that the index was a regular file.

I have also added a test case for this situation.
