Discard two leading slashes from the beginning of a `file:` URI if they
introduce an empty authority section. As a result, file URIs like
`///etc/hosts` are correctly parsed as `/etc/hosts`.
* gh-123832: Adjust `socket.getaddrinfo` docs for better POSIX compliance
This changes nothing changes for CPython supported platforms,
but hints how to deal with platforms that stick to the letter of
the spec.
It also marks `socket.getaddrinfo` as a wrapper around `getaddrinfo(3)`;
specifically, workarounds to make the function work consistently across
platforms are out of scope in its code.
Include wording similar to the POSIX's “by providing options and by
limiting the returned information”, which IMO suggests that the
hints limit the resulting list compared to the defaults, *but* can
be interpreted differently. Details are added in a note.
Specifically say that this wraps the underlying C function. So, the
details are in OS docs. The “full range of results” bit goes away.
Use `AF_UNSPEC` rather than zero for the *family* default, although
I don't think a system where it's nonzero would be very usable.
Suggest setting proto and/or type (with examples, as the appropriate
values aren't obvious). Say why you probably want to do that that
on all systems; mention the behavior on the “letter of the spec”
systems.
Suggest that the results should be tried in order, which is,
AFAIK best practice -- see RFC 6724 section 2, and its predecessor
from 2003 (which are specific to IP, but indicate how people use this):
> Well-behaved applications SHOULD iterate through the list of
> addresses returned from `getaddrinfo()` until they find a working address.

One of the most common reasons I see the old `pipes` module still in use
when porting to Python 3.13 is for the undocumented `pipes.quote`
function, which can easily be replaced with `shlex.quote`. I think it's
worth specifically calling this out, since being directed to the
`subprocess` module would be confusing in this case.
In strict mode, raise `NotADirectoryError` if we encounter a non-directory
while we still have path parts left to process.
We use a `part_count` variable rather than `len(rest)` because the `rest`
stack also contains markers for unresolved symlinks.
* gh-71936: Fix race condition in multiprocessing.Pool
Proxes of shared objects register a Finalizer in BaseProxy._incref(), and it
will call BaseProxy._decref() when it is GCed. This may cause a race condition
with Pool(maxtasksperchild=None) on Windows.
A connection would be closed and raised TypeError when a GC occurs between
_ConnectionBase._check_writable() and _ConnectionBase._send_bytes() in
_ConnectionBase.send() in the second or later task, and a new object
is allocated that shares the id() of a previously deleted one.
Instead of using the id() of the token (or the proxy), use a unique,
non-reusable number.

Previously, this would cause an `AttributeError` if the patch stopped more than once after this, and would also disrupt the original patched object.

The PyMutex implementation supports unlocking after fork because we
clear the list of waiters in parking_lot.c. This doesn't work as well
for _PyRecursiveMutex because on some systems, such as SerenityOS, the
thread id is not preserved across fork().
Accepting objects with false values (like 0 and []) except empty strings
and byte-like objects and None in urllib.parse functions parse_qsl() and
parse_qs() is now deprecated.
These changes makes it easier to backport the _interpreters, _interpqueues, and _interpchannels modules to Python 3.12.
This involves the following:
* add the _PyXI_GET_STATE() and _PyXI_GET_GLOBAL_STATE() macros
* add _PyXIData_lookup_context_t and _PyXIData_GetLookupContext()
* add _Py_xi_state_init() and _Py_xi_state_fini()

* Removes erroneous explanation of the `global` statement restrictions; a name declared as global can be subsequently bound using any kind of name binding operation.
* Updates `test_global.py` to also test various name-binding scenarios for global
variables to ensure correct behavior
These changes makes it easier to backport the _interpreters, _interpqueues, and _interpchannels modules to Python 3.12.
This involves the following:
* rename several structs and typedefs
* add several typedefs
* stop using the PyThreadState.state field directly in parking_lot.c
