Subject: [PATCH] bpo-46811: Make test suite support Expat >=2.4.5 (GH-31453)
(GH-31472)
Curly brackets were never allowed in namespace URIs
according to RFC 3986, and so-called namespace-validating
XML parsers have the right to reject them a invalid URIs.
libexpat >=2.4.5 has become strcter in that regard due to
related security issues; with ET.XML instantiating a
namespace-aware parser under the hood, this test has no
future in CPython.
References:
- https://datatracker.ietf.org/doc/html/rfc3968
- https://www.w3.org/TR/xml-names/
Also, test_minidom.py: Support Expat >=2.4.5
(cherry picked from commit 2cae93832f46b245847bdc252456ddf7742ef45e)

Subject: [PATCH] gh-114572: Fix locking in cert_store_stats and get_ca_certs
(GH-114573)
* gh-114572: Fix locking in cert_store_stats and get_ca_certs
cert_store_stats and get_ca_certs query the SSLContext's X509_STORE with
X509_STORE_get0_objects, but reading the result requires a lock. See
https://github.com/openssl/openssl/pull/23224 for details.
Instead, use X509_STORE_get1_objects, newly added in that PR.
X509_STORE_get1_objects does not exist in current OpenSSLs, but we can
polyfill it with X509_STORE_lock and X509_STORE_unlock.
* Work around const-correctness problem
* Add missing X509_STORE_get1_objects failure check
* Add blurb
(cherry picked from commit bce693111bff906ccf9281c22371331aaff766ab)

Subject: [PATCH] gh-113171: gh-65056: Fix "private" (non-global) IP address
ranges (GH-113179) (GH-113186) (GH-118177)
* GH-113171: Fix "private" (non-global) IP address ranges (GH-113179)
The _private_networks variables, used by various is_private
implementations, were missing some ranges and at the same time had
overly strict ranges (where there are more specific ranges considered
globally reachable by the IANA registries).
This patch updates the ranges with what was missing or otherwise
incorrect.
100.64.0.0/10 is left alone, for now, as it's been made special in [1].
The _address_exclude_many() call returns 8 networks for IPv4, 121
networks for IPv6.
[1] https://github.com/python/cpython/issues/61602
* GH-65056: Improve the IP address' is_global/is_private documentation (GH-113186)
It wasn't clear what the semantics of is_global/is_private are and, when
one gets to the bottom of it, it's not quite so simple (hence the
exceptions listed).
(cherry picked from commit 2a4cbf17af19a01d942f9579342f77c39fbd23c4)
(cherry picked from commit 40d75c2b7f5c67e254d0a025e0f2e2c7ada7f69f)

Subject: [PATCH] [3.11] gh-121650: Encode newlines in headers, and verify
headers are sound (GH-122233)
GH-GH- Encode header parts that contain newlines
Per RFC 2047:
> [...] these encoding schemes allow the
> encoding of arbitrary octet values, mail readers that implement this
> decoding should also ensure that display of the decoded data on the
> recipient's terminal will not cause unwanted side-effects
It seems that the "quoted-word" scheme is a valid way to include
a newline character in a header value, just like we already allow
undecodable bytes or control characters.
They do need to be properly quoted when serialized to text, though.
GH-GH- Verify that email headers are well-formed
This should fail for custom fold() implementations that aren't careful
about newlines.

Subject: [PATCH] 00251: Change user install location
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Set values of base and platbase in sysconfig from /usr
to /usr/local when RPM build is not detected
to make pip and similar tools install into separate location.
Fedora Change: https://fedoraproject.org/wiki/Changes/Making_sudo_pip_safe
Downstream only.
We've tried to rework in Fedora 36/Python 3.10 to follow https://bugs.python.org/issue43976
but we have identified serious problems with that approach,
see https://bugzilla.redhat.com/2026979 or https://bugzilla.redhat.com/2097183

and multissltests to use 3.0.15, 3.1.7, and 3.2.3.
- Tests
- gh-125041: Re-enable skipped tests for zlib on the
s390x architecture: only skip checks of the compressed
bytes, which can be different between zlib’s software
implementation and the hardware-accelerated implementation.
- Security
- gh-126623: Upgrade libexpat to 2.6.4
- gh-122792: Changed IPv4-mapped ipaddress.IPv6Address to

- Update to 3.11.10:
- Security
- gh-123678: Upgrade libexpat to 2.6.3
- gh-121957: Fixed missing audit events around interactive
use of Python, now also properly firing for ``python -i``,
as well as for ``python -m asyncio``. The event in question
is ``cpython.run_stdin``.
- gh-122133: Authenticate the socket connection for the
``socket.socketpair()`` fallback on platforms where
``AF_UNIX`` is not available like Windows. Patch by
Gregory P. Smith <greg@krypto.org> and Seth Larson
<seth@python.org>. Reported by Ellie <el@horse64.org>
- gh-121285: Remove backtracking from tarfile header parsing
for ``hdrcharset``, PAX, and GNU sparse headers
(bsc#1230227, CVE-2024-6232).
- gh-118486: :func:`os.mkdir` on Windows now accepts
*mode* of ``0o700`` to restrict the new directory to
the current user. This fixes CVE-2024-4030 affecting
:func:`tempfile.mkdtemp` in scenarios where the base
temporary directory is more permissive than the default.
- gh-116741: Update bundled libexpat to 2.6.2
- Library
- gh-123270: Applied a more surgical fix for malformed
payloads in :class:`zipfile.Path` causing infinite loops
(gh-122905) without breaking contents using legitimate
characters (bsc#1229704, CVE-2024-8088).
- gh-123067: Fix quadratic complexity in parsing ``"``-quoted
cookie values with backslashes by :mod:`http.cookies`
(bsc#1229596, CVE-2024-7592).
- gh-122905: :class:`zipfile.Path` objects now sanitize names
from the zipfile.
- gh-121650: :mod:`email` headers with embedded newlines are
now quoted on output. The :mod:`~email.generator` will now
refuse to serialize (write) headers that are unsafely folded
or delimited; see :attr:`~email.policy.Policy.verify_generated_headers`.
(Contributed by Bas Bloemsaat and Petr Viktorin in
:gh:`121650`; CVE-2024-6923, bsc#1228780).
- gh-119506: Fix :meth:`!io.TextIOWrapper.write` method
breaks internal buffer when the method is called again
during flushing internal buffer.
- gh-118643: Fix an AttributeError in the :mod:`email` module
when re-fold a long address list. Also fix more cases of
incorrect encoding of the address separator in the address
list.
- gh-113171: Fixed various false positives and false
negatives in * :attr:`ipaddress.IPv4Address.is_private`
(see these docs for details) *
:attr:`ipaddress.IPv4Address.is_global` *
:attr:`ipaddress.IPv6Address.is_private` *
:attr:`ipaddress.IPv6Address.is_global` Also in the
corresponding :class:`ipaddress.IPv4Network` and
:class:`ipaddress.IPv6Network` attributes.
Fixes bsc#1226448 (CVE-2024-4032).
- gh-102988: :func:`email.utils.getaddresses` and
:func:`email.utils.parseaddr` now return ``('', '')``
2-tuples in more situations where invalid email addresses
are encountered instead of potentially inaccurate
values. Add optional *strict* parameter to these two
functions: use ``strict=False`` to get the old behavior,
accept malformed inputs. ``getattr(email.utils,
'supports_strict_parsing', False)`` can be use to check if
the *strict* paramater is available. Patch by Thomas Dwyer
and Victor Stinner to improve the CVE-2023-27043 fix
(bsc#1210638).
- gh-67693: Fix :func:`urllib.parse.urlunparse` and
:func:`urllib.parse.urlunsplit` for URIs with path starting
with multiple slashes and no authority. Based on patch by
Ashwin Ramaswami.
- Core and Builtins
- gh-112275: A deadlock involving ``pystate.c``'s
``HEAD_LOCK`` in ``posixmodule.c`` at fork is now
fixed. Patch by ChuBoning based on previous Python 3.12 fix
by Victor Stinner.

used in assignment expressions in comprehensions.
* Library
- gh-117310: Fixed an unlikely early & extra Py_DECREF triggered

support bytes arguments containing raw and percent-encoded
non-ASCII data.
- gh-67044: csv.writer() now always quotes or escapes '\r' and
'\n', regardless of lineterminator value.

a space and skipinitialspace is true and raises exception if
quoting is not possible.
- gh-115618: Fix improper decreasing the reference count for None
argument in property methods getter(), setter() and deleter().
- gh-115570: A DeprecationWarning is no longer omitted on access
to the __doc__ attributes of the deprecated typing.io and
typing.re pseudo-modules.

- gh-115392: Fix a bug in doctest where incorrect line numbers
would be reported for decorated functions.
- gh-114563: Fix several format() bugs when using the C
implementation of Decimal: * memory leak in some rare cases when
using the z format option (coerce negative 0) * incorrect output

non-existing paths in recursive glob().
- gh-114763: Protect modules loaded with importlib.util.LazyLoader
from race conditions when multiple threads try to access
attributes before the loading is complete.
- gh-97959: Fix rendering class methods, bound methods, method and
function aliases in pydoc. Class methods no longer have “method
of builtins.type instance” note. Corresponding notes are now
added for class and unbound methods. Method and function aliases
now have references to the module or the class where the origin
was defined if it differs from the current. Bound methods are
now listed in the static methods section. Methods of builtin
classes are now supported as well as methods of Python classes.

argparse.
- bpo-43952: Fix multiprocessing.connection.Listener.accept() to
accept empty bytes as authkey. Not accepting empty bytes as key
causes it to hang indefinitely.
- bpo-42125: linecache: get module name from __spec__ if
available. This allows getting source code for the __main__
module when a custom loader is used.
- gh-66543: Make mimetypes.guess_type() properly parsing of URLs
with only a host name, URLs containing fragment or query, and
filenames with only a UNC sharepoint on Windows. Based on patch
by Dong-hee Na.

that sending a datagram to an address that is not listening does
not prevent receiving any more datagrams.
- gh-115554: The installer now has more strict rules about
updating the Python Launcher for Windows. In general, most users
only have a single launcher installed and will see no
difference. When multiple launchers have been installed, the
option to install the launcher is disabled until all but one
have been removed. Downgrading the launcher (which was never
allowed) is now more obviously blocked.
- gh-115543: Python Launcher for Windows can now detect Python
3.13 when installed from the Microsoft Store, and will install
Python 3.12 by default when PYLAUNCHER_ALLOW_INSTALL is set.
- gh-115009: Update Windows installer to use SQLite 3.45.1.
* IDLE
- gh-88516: On macOS show a proxy icon in the title bar of editor
windows to match platform behaviour.
* Tools/Demos
