Since 6258844c, paths that might not exist can be fed into pathlib's
globbing implementation, which will call `os.scandir()` / `os.lstat()` only
when strictly necessary. This allows us to drop an initial `self.is_dir()`
call, which saves a `stat()`.

rfc9110 obsoletes the earlier rfc 7231. This document also includes some
status codes that were previously only used for WebDAV and assigns more
generic names to these status codes.
ref: https://www.rfc-editor.org/rfc/rfc9110.html#name-changes-from-rfc-7231
- http.HTTPStatus.CONTENT_TOO_LARGE (413, previously
REQUEST_ENTITY_TOO_LARGE)
- http.HTTPStatus.URI_TOO_LONG (414, previously REQUEST_URI_TOO_LONG)
- http.HTTPStatus.RANGE_NOT_SATISFYABLE (416, previously
REQUEST_RANGE_NOT_SATISFYABLE)
- http.HTTPStatus.UNPROCESSABLE_CONTENT (422, previously
UNPROCESSABLE_ENTITY)
The new constants are added to http.HTTPStatus and the old constant names are
preserved for backwards compatibility.
References in documentation to the obsoleted rfc 7231 are updated
I think the choice of wording in these docs is great and doesn't
need to change. However, it could be useful to explicitly define
this term / the cost of doing so seems relatively low.
Guido pointed out to me that some details about the per-interpreter state for the builtin types aren't especially clear. I'm addressing that by:
* adding a comment explaining that state
* adding some asserts to point out the relationship between each index and the interp/global runtime state
Replace use of `os.listdir()` with `os.scandir()`. Forgo setting `_drv`,
`_root` and `_tail_cached`, as these usually aren't needed. Use
`os.DirEntry.path` to set `_str`.
Don't bother calling `os.scandir()` to scan for literal pattern segments,
like `foo` in `foo/*.py`. Instead, append the segment(s) as-is and call
through to the next selector with `exists=False`, which signals that the
path might not exist. Subsequent selectors will call `os.scandir()` or
`os.lstat()` to filter out missing paths as needed.
Test signatures of all public builtins and methods of builtin classes
in modules builtins, types, sys, and several other modules (either
included in the list of standard builtin modules sys.builtin_module_names,
or providing a public interface for such modules).
Most builtins should have supported signatures, with few known exceptions.
When more builtins will be converted to Argument Clinic or support of
new signatures be implemented, they will be removed from the exception
lists.
This change gives a significant speedup, as the METH_FASTCALL calling
convention is now used. The following bytes and bytearray methods are adapted:
- count()
- find()
- index()
- rfind()
- rindex()

This is similar to the situation with threading._DummyThread. The methods (incl. __del__()) of interpreters.Interpreter objects must be careful with interpreters not created by interpreters.create(). The simplest thing to start with is to disable any method that modifies or runs in the interpreter. As part of this, the runtime keeps track of where an interpreter was created. We also handle interpreter "refcounts" properly.
The free-threaded build does not currently support the combination of
single-phase init modules and non-isolated subinterpreters. Ensure that
`check_multi_interp_extensions` is always `True` for subinterpreters in
the free-threaded build so that importing these modules raises an
`ImportError`.
Detect libcrypto BLAKE2, Shake, SHA3, and Truncated-SHA512 support at hashlib build time
## BLAKE2
While OpenSSL supports both "b" and "s" variants of the BLAKE2 hash
function, other cryptographic libraries may lack support for one or both
of the variants. This commit modifies `hashlib`'s C code to detect
whether or not the linked libcrypto supports each BLAKE2 variant, and
elides references to each variant's NID accordingly. In cases where the
underlying libcrypto doesn't fully support BLAKE2, CPython's
`./configure` script can be given the following flag to use CPython's
interned BLAKE2 implementation: `--with-builtin-hashlib-hashes=blake2`.
## SHA3, Shake, & truncated SHA512.
Detect BLAKE2, SHA3, Shake, & truncated SHA512 support in the
OpenSSL-ish libcrypto library at build time. This helps allow hashlib's
`_hashopenssl` to be used with libraries that do not to support every
algorithm that upstream OpenSSL does. Such as AWS-LC & BoringSSL.

gh-16429 introduced support for an iterable of separators in
Stream.readuntil. Since bytes-like types are themselves iterable, this
can introduce ambiguities in deciding whether the argument is an
iterator of separators or a singleton separator. In gh-16429, only 'bytes'
was considered a singleton, but this will break code that passes other
buffer object types.
Fix it by only supporting tuples rather than arbitrary iterables.
Closes gh-117722.
Fall back to tp_call() for cases when arguments are passed by name.
