hidden file attribute.
- Core and Builtins
- gh-114887: Changed socket type validation in
create_datagram_endpoint() to accept all non-stream sockets.
This fixes a regression in compatibility with raw sockets.
- gh-114388: Fix a RuntimeWarning emitted when assign an
integer-like value that is not an instance of int to an
attribute that corresponds to a C struct member of type T_UINT
and T_ULONG. Fix a double RuntimeWarning emitted when assign a
negative integer value to an attribute that corresponds to a C
struct member of type T_UINT.
- gh-89811: Check for a valid tp_version_tag before performing
bytecode specializations that rely on this value being usable.
- gh-113602: Fix an error that was causing the parser to try to
overwrite existing errors and crashing in the process. Patch by
Pablo Galindo
- gh-113566: Fix a 3.11-specific crash when the repr of a Future
is requested after the module has already been
garbage-collected.
- gh-106905: Use per AST-parser state rather than global state to
track recursion depth within the AST parser to prevent potential
race condition due to simultaneous parsing.
- The issue primarily showed up in 3.11 by multithreaded users of
ast.parse(). In 3.12 a change to when garbage collection can be
triggered prevented the race condition from occurring.
- gh-112716: Fix SystemError in the import statement and in
__reduce__() methods of builtin types when __builtins__ is not a
dict.
- gh-105967: Workaround a bug in Apple’s macOS platform zlib
library where zlib.crc32() and binascii.crc32() could produce
incorrect results on multi-gigabyte inputs. Including when using
zipfile on zips containing large data.
- gh-94606: Fix UnicodeEncodeError when
email.message.get_payload() reads a message with a Unicode
surrogate character and the message content is not well-formed
for surrogateescape encoding. Patch by Sidney Markowitz.
- Library
- gh-114965: Update bundled pip to 24.0
- gh-114959: tarfile no longer ignores errors when trying to
extract a directory on top of a file.
- gh-109475: Fix support of explicit option value “–” in argparse
(e.g. --option=--).
- gh-110190: Fix ctypes structs with array on Windows ARM64
platform by setting MAX_STRUCT_SIZE to 32 in stgdict. Patch by
Diego Russo
- gh-113280: Fix a leak of open socket in rare cases when error
occurred in ssl.SSLSocket creation.
- gh-77749: email.policy.EmailPolicy.fold() now always encodes
non-ASCII characters in headers if utf8 is false.
- gh-114492: Make the result of termios.tcgetattr() reproducible
on Alpine Linux. Previously it could leave a random garbage in
some fields.
- gh-75128: Ignore an OSError in
asyncio.BaseEventLoop.create_server() when IPv6 is available but
the interface cannot actually support it.
- gh-114257: Dismiss the FileNotFound error in
ctypes.util.find_library() and just return None on Linux.
- gh-101438: Avoid reference cycle in ElementTree.iterparse. The
iterator returned by ElementTree.iterparse may hold on to a file
descriptor. The reference cycle prevented prompt clean-up of the
file descriptor if the returned iterator was not exhausted.
- gh-104522: OSError raised when run a subprocess now only has
filename attribute set to cwd if the error was caused by a
failed attempt to change the current directory.

string using d in the decimals part creates a different error
compared to other invalid letters/characters. Patch by Jeremiah
Gabriel Pascual.
- gh-113951: Fix the behavior of tag_unbind() methods of
tkinter.Text and tkinter.Canvas classes with three arguments.
Previously, widget.tag_unbind(tag, sequence, funcid) destroyed
the current binding for sequence, leaving sequence unbound, and
deleted the funcid command. Now it removes only funcid from the
binding for sequence, keeping other commands, and deletes the
funcid command. It leaves sequence unbound only if funcid was
the last bound command.
- gh-113877: Fix tkinter method winfo_pathname() on 64-bit
Windows.
- gh-113781: Silence unraisable AttributeError when warnings are
emitted during Python finalization.
- gh-113594: Fix UnicodeEncodeError in email when re-fold lines
that contain unknown-8bit encoded part followed by
non-unknown-8bit encoded part.
- gh-113538: In asyncio.StreamReaderProtocol.connection_made(),
there is callback that logs an error if the task wrapping the
“connected callback” fails. This callback would itself fail if
the task was cancelled. Prevent this by checking whether the
task was cancelled first. If so, close the transport but don’t
log an error.
- gh-85567: Fix resource warnings for unclosed files in pickle and
pickletools command line interfaces.
- gh-101225: Increase the backlog for
multiprocessing.connection.Listener objects created by
multiprocessing.manager and multiprocessing.resource_sharer to
significantly reduce the risk of getting a connection refused
error when creating a multiprocessing.connection.Connection to
them.
- gh-113543: Make sure that webbrowser.MacOSXOSAScript sends
webbrowser.open audit event.
- gh-113028: When a second reference to a string appears in the
input to pickle, and the Python implementation is in use, we are
guaranteed that a single copy gets pickled and a single object
is shared when reloaded. Previously, in protocol 0, when a
string contained certain characters (e.g. newline) it resulted
in duplicate objects.
- gh-113421: Fix multiprocessing logger for %(filename)s.
- gh-113358: Fix rendering tracebacks for exceptions with a broken
__getattr__.
- gh-113214: Fix an AttributeError during asyncio SSL protocol
aborts in SSL-over-SSL scenarios.
- gh-113246: Update bundled pip to 23.3.2.
- gh-113199: Make http.client.HTTPResponse.read1 and
http.client.HTTPResponse.readline close IO after reading all
data when content length is known. Patch by Illia Volochii.
- gh-113188: Fix shutil.copymode() and shutil.copystat() on
Windows. Previously they worked differenly if dst is a symbolic
link: they modified the permission bits of dst itself rather
than the file it points to if follow_symlinks is true or src is
not a symbolic link, and did not modify the permission bits if
follow_symlinks is false and src is a symbolic link.
- gh-61648: Detect line numbers of properties in doctests.
- gh-112559: signal.signal() and signal.getsignal() no longer call
repr on callable handlers. asyncio.run() and
asyncio.Runner.run() no longer call repr on the task results.
Patch by Yilei Yang.
- gh-110190: Fix ctypes structs with array on PPC64LE platform by
setting MAX_STRUCT_SIZE to 64 in stgdict. Patch by Diego Russo.
- gh-79429: Ignore FileNotFoundError when remove a temporary
directory in the multiprocessing finalizer.
- gh-79325: Fix an infinite recursion error in
tempfile.TemporaryDirectory() cleanup on Windows.
- gh-110190: Fix ctypes structs with array on Arm platform by
setting MAX_STRUCT_SIZE to 32 in stgdict. Patch by Diego Russo.
- gh-81194: Fix a crash in socket.if_indextoname() with specific
value (UINT_MAX). Fix an integer overflow in
socket.if_indextoname() on 64-bit non-Windows platforms.
- gh-75666: Fix the behavior of tkinter widget’s unbind() method
with two arguments. Previously, widget.unbind(sequence, funcid)
destroyed the current binding for sequence, leaving sequence
unbound, and deleted the funcid command. Now it removes only
funcid from the binding for sequence, keeping other commands,
and deletes the funcid command. It leaves sequence unbound only
if funcid was the last bound command.
- gh-110345: Show the Tcl/Tk patchlevel (rather than version) in
tkinter._test().
- gh-109858: Protect zipfile from “quoted-overlap” zipbomb. It now
raises BadZipFile when try to read an entry that overlaps with
other entry or central directory.
- gh-38807: Fix race condition in trace. Instead of checking if a
directory exists and creating it, directly call os.makedirs()
with the kwarg exist_ok=True.
- gh-75705: Set unixfrom envelope in mailbox.mbox and
mailbox.MMDF.
- gh-105102: Allow ctypes.Union to be nested in ctypes.Structure
when the system endianness is the opposite of the classes.
- gh-104282: Fix null pointer dereference in
lzma._decode_filter_properties() due to improper handling of BCJ
filters with properties of zero length. Patch by Radislav
Chugunov.
- gh-102512: When os.fork() is called from a foreign thread (aka
_DummyThread), the type of the thread in a child process is
changed to _MainThread. Also changed its name and daemonic
status, it can be now joined.
- gh-91133: Fix a bug in tempfile.TemporaryDirectory cleanup,
which now no longer dereferences symlinks when working around
file system permission errors.
- bpo-43153: On Windows, tempfile.TemporaryDirectory previously
masked a PermissionError with NotADirectoryError during
directory cleanup. It now correctly raises PermissionError if
errors are not ignored. Patch by Andrei Kulakov and Ken Jin.
- bpo-35332: The shutil.rmtree() function now ignores errors when
calling os.close() when ignore_errors is True, and os.close() no
longer retried after error.
- bpo-35928: io.TextIOWrapper now correctly handles the decoding
buffer after read() and write().
- bpo-26791: shutil.move() now moves a symlink into a directory
when that directory is the target of the symlink. This provides
the same behavior as the mv shell command. The previous behavior
raised an exception. Patch by Jeffrey Kintscher.
- bpo-36959: Fix some error messages for invalid ISO format string
combinations in strptime() that referred to directives not
contained in the format string. Patch by Gordon P. Hemsley.
- bpo-18060: Fixed a class inheritance issue that can cause
segfaults when deriving two or more levels of subclasses from a
base class of Structure or Union.

from v0.16.0 of the uvloop project, as well as the required MIT
licensing information.
- Tests
- gh-109980: Fix test_tarfile_vs_tar in test_shutil for macOS,
where system tar can include more information in the archive
than shutil.make_archive.

zlib.ZLIB_RUNTIME_VERSION contains non-integer suffixes. For
example zlib-ng defines the version as 1.3.0.zlib-ng.
- gh-105089: Fix
test.test_zipfile.test_core.TestWithDirectory.test_create_directory_with_write
test in AIX by doing a bitwise AND of 0xFFFF on mode , so that
it will be in sync with zinfo.external_attr
- bpo-40648: Test modes that file can get with chmod() on Windows.

files and recommend appropriate source tree cleanup steps to get
a working build again.
- bpo-11102: The os.major(), os.makedev(), and os.minor()
functions are now available on HP-UX v3.

- gh-115015: Fix a bug in Argument Clinic that generated incorrect
code for methods with no parameters that use the METH_METHOD |
METH_FASTCALL | METH_KEYWORDS calling convention. Only the
positional parameter count was checked; any keyword argument
passed would be silently accepted.

Linux ppc64le (ex: Fedora 38). Search patterns in gdb “bt”
command output to detect when gdb fails to retrieve the
traceback. For example, skip a test if Backtrace stopped: frame
did not save the PC is found. Patch by Victor Stinner.
- gh-108927: Fixed order dependence in running tests in the same
process when a test that has submodules (e.g. test_importlib)
follows a test that imports its submodule (e.g.
test_importlib.util) and precedes a test (e.g. test_unittest or
test_compileall) that uses that submodule.
- Build

of libedit.
- IDLE
- bpo-35668: Add docstrings to the IDLE debugger module. Fix two

- gh-112438: Fix support of format units “es”, “et”, “es#”, and
“et#” in nested tuples in PyArg_ParseTuple()-like functions.
- gh-109521: PyImport_GetImporter() now sets RuntimeError if it
fails to get sys.path_hooks or sys.path_importer_cache or they
are not list and dict correspondingly. Previously it could
return NULL without setting error in obscure cases, crash or
raise SystemError if these attributes have wrong type.

- gh-108310: Fixed an issue where instances of ssl.SSLSocket were
vulnerable to a bypass of the TLS handshake and included
protections (like certificate verification) and treating sent
unencrypted data as if it were post-handshake TLS encrypted data.
Security issue reported as CVE-2023-40217 by Aapo Oksman. Patch by
Gregory P. Smith.
- Core and Builtins
- gh-104432: Fix potential unaligned memory access on C APIs
involving returned sequences of char * pointers within the grp
and socket modules. These were revealed using a
-fsaniziter=alignment build on ARM macOS. Patch by Christopher
Chavez.
- gh-77377: Ensure that multiprocessing synchronization objects
created in a fork context are not sent to a different process
created in a spawn context. This changes a segfault into an
actionable RuntimeError in the parent process.

bug in frame_dealloc when the trashcan delays the deallocation
of a PyFrameObject.
- gh-106719: No longer suppress arbitrary errors in the
__annotations__ getter and setter in the type and module types.
- gh-106723: Propagate frozen_modules to multiprocessing spawned
process interpreters.
- gh-105979: Fix crash in _imp.get_frozen_object() due to improper
exception handling.

partially reverting CVE-2023-27043-email-parsing-errors.patch,
because of the regression in gh#python/cpython#106669.
- (bsc#1210638, CVE-2023-27043) Add
CVE-2023-27043-email-parsing-errors.patch, which detects email
address parsing errors and returns empty tuple to indicate the
parsing error (old API). (The patch is faulty,
gh#python/cpython#106669, but upstream decided not to just
revert it).

- gh-103142: The version of OpenSSL used in Windows and
Mac installers has been upgraded to 1.1.1u to address
CVE-2023-2650, CVE-2023-0465, CVE-2023-0466, CVE-2023-0464,
as well as CVE-2023-0286, CVE-2022-4303, and CVE-2022-4303
fixed previously in 1.1.1t (gh-101727).
- gh-102153: urllib.parse.urlsplit() now strips leading C0
control and space characters following the specification for
URLs defined by WHATWG in response to CVE-2023-24329
(bsc#1208471).
- gh-99889: Fixed a security in flaw in uu.decode() that could
allow for directory traversal based on the input if no
out_file was specified.
- gh-104049: Do not expose the local on-disk
location in directory indexes produced by
http.client.SimpleHTTPRequestHandler.
- gh-103935: trace.__main__ now uses io.open_code() for files
to be executed instead of raw open().
- gh-102953: The extraction methods in tarfile, and
shutil.unpack_archive(), have a new filter argument that
allows limiting tar features than may be surprising or
dangerous, such as creating files outside the destination
directory. See Extraction filters for details (fixing
CVE-2007-4559, bsc#1203750).

- python -m http.server no longer allows terminal control
characters sent within a garbage request to be printed
to the stderr server lo This is done by changing the
http.server BaseHTTPRequestHandler .log_message method to
replace control characters with a \xHH hex escape before
printin
- Avoid publishing list of active per-interpreter audit hooks
via the gc module
- The IDNA codec decoder used on DNS hostnames by socket or
asyncio related name resolution functions no longer involves
a quadratic algorithm. This prevents a potential CPU denial
of service if an out-of-spec excessive length hostname
involving bidirectional characters were decoded. Some
protocols such as urllib http 3xx redirects potentially allow
for an attacker to supply such a name (CVE-2022-45061).
- Update bundled libexpat to 2.5.0
- Fix a shell code injection vulnerability in the
get-remote-certificate.py example script. The script no
longer uses a shell to run openssl commands. Issue reported
and initial fix by Caleb Shortt. Patch by Victor Stinner.
- Fix a crash when an object which does not have a dictionary
frees its instance values.
- Fix a bug in the tokenizer that could cause infinite
recursion when showing syntax warnings that happen in the
first line of the source. Patch by Pablo Galindo
- Fix an issue that could cause frames to be visible to Python
code as they are being torn down, possibly leading to memory
corruption or hard crashes of the interpreter.

- Update to 3.11.0 (overall changes from 3.10.*):
- General changes
- PEP 657 -- Include Fine-Grained Error Locations in
Tracebacks
- PEP 654 -- Exception Groups and except*
- PEP 680 -- tomllib: Support for Parsing TOML in the
Standard Library
- gh-90908 -- Introduce task groups to asyncio
- gh-34627 -- Atomic grouping ((?>...)) and possessive
quantifiers (*+, ++, ?+, {m,n}+) are now supported in
regular expressions.
- The Faster CPython Project is already yielding some
exciting results. Python 3.11 is up to 10-60% faster than
Python 3.10. On average, we measured a 1.22x speedup on the
standard benchmark suite. See Faster CPython for details.
- Typing and typing language changes
- PEP 673 -- Self Type
- PEP 646 -- Variadic Generics
- PEP 675 -- Arbitrary Literal String Type
- PEP 655 -- Marking individual TypedDict items as required
or potentially-missing
- PEP 681 -- Data Class Transforms
- (just changes from 3.11.0rc2):
- Fix multiplying a list by an integer (list *= int): detect
the integer overflow when the new allocated length is close
to the maximum size. Issue reported by Jordan Limor. Patch by
Victor Stinner.

- Converting between int and str in bases other than 2
(binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base
10 (decimal) now raises a ValueError if the number of digits
in string form is above a limit to avoid potential denial of
service attacks due to the algorithmic complexity. This is
a mitigation for CVE-2020-10735.
This new limit can be configured or disabled by environment
variable, command line flag, or sys APIs. See the integer
string conversion length limitation documentation. The
default limit is 4300 digits in string form.
- Fix case of undefined behavior in ceval.c
- Do not expose KeyWrapper in _functools.
- Ensure that tracing, sys.setrace(), is turned on
immediately. In pre-release versions of 3.11, some tracing
events might have been lost when turning on tracing in a
__del__ method or interrupt.
- Fix use after free in trace refs build mode. Patch by Kumar
Aditya.
- When loading a file with invalid UTF-8 inside a multi-line
string, a correct SyntaxError is emitted.
- Make sure that incomplete frames do not show up in
tracemalloc traces.
- Remove two cases of undefined behavior, by adding NULL
checks.
- Fix possible NULL pointer dereference in
_PyThread_CurrentFrames. Patch by Kumar Aditya.
- Fix AttributeError missing name and obj attributes in
object.__getattribute__(). Patch by Philip Georgi.
