- Update to 3.11.8:
- Security
- gh-113659: Skip .pth files with names starting with a dot or
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.
- gh-109534: Fix a reference leak in
asyncio.selector_events.BaseSelectorEventLoop when SSL
handshakes fail. Patch contributed by Jamie Phan.
- gh-114077: Fix possible OverflowError in
socket.socket.sendfile() when pass count larger than 2 GiB on
32-bit platform.
- gh-114014: Fixed a bug in fractions.Fraction where an invalid
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.

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.
- gh-112769: The tests now correctly compare zlib version when
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.
- Build
- gh-101778: Fix build error when there’s a dangling symlink in
the directory containing ffi.h.
- gh-112305: Fixed the check-clean-src step performed on out of
tree builds to detect errant $(srcdir)/Python/frozen_modules/*.h
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
- gh-103053: “make check-clean-src” now also checks if the
“python” program is found in the source directory: fail with an
error if it does exist. Patch by Victor Stinner.
- gh-109191: Fix compile error when building with recent versions
of libedit.
- IDLE
- bpo-35668: Add docstrings to the IDLE debugger module. Fix two
bugs: initialize Idb.botframe (should be in Bdb); in
Idb.in_rpc_code, check whether prev_frame is None before trying
to use it. Greatly expand test_debugger.
- C API
- 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.
* Mon Dec 18 2023 mcepl@cepl.eu
- Refresh CVE-2023-27043-email-parsing-errors.patch to
gh#python/cpython!111116, fixing bsc#1210638 (CVE-2023-27043).
- Thus we can remove Revert-gh105127-left-tests.patch, which is
now useless.
* Wed Nov 15 2023 daniel.garcia@suse.com
- Remove not needed patch 103213-fetch-CONFIG_ARGS.patch
- Refresh patches:
- bpo-31046_ensurepip_honours_prefix.patch
- fix_configure_rst.patch
- Update to 3.11.6:
- Core and Builtins
- gh-109351: Fix crash when compiling an invalid AST involving a
named (walrus) expression.
- gh-109207: Fix a SystemError in __repr__ of symtable entry
object.
- gh-109179: Fix bug where the C traceback display drops notes
from SyntaxError.
- gh-88943: Improve syntax error for non-ASCII character that
follows a numerical literal. It now points on the invalid
non-ASCII character, not on the valid numerical literal.
- gh-108959: Fix caret placement for error locations for subscript
and binary operations that involve non-semantic parentheses and
spaces. Patch by Pablo Galindo
- gh-108520: Fix
multiprocessing.synchronize.SemLock.__setstate__() to properly
initialize multiprocessing.synchronize.SemLock._is_fork_ctx.
This fixes a regression when passing a SemLock accross nested
processes.
- Rename multiprocessing.synchronize.SemLock.is_fork_ctx to
multiprocessing.synchronize.SemLock._is_fork_ctx to avoid
exposing it as public API.
- Library
- gh-110036: On Windows, multiprocessing Popen.terminate() now
catchs PermissionError and get the process exit code. If the
process is still running, raise again the PermissionError.
Otherwise, the process terminated as expected: store its exit
code. Patch by Victor Stinner.
- gh-110038: Fixed an issue that caused KqueueSelector.select() to
not return all the ready events in some cases when a file
descriptor is registered for both read and write.
- gh-109631: re functions such as re.findall(), re.split(),
re.search() and re.sub() which perform short repeated matches
can now be interrupted by user.
- gh-109593: Avoid deadlocking on a reentrant call to the
multiprocessing resource tracker. Such a reentrant call, though
unlikely, can happen if a GC pass invokes the finalizer for a
multiprocessing object such as SemLock.
- gh-109613: Fix os.stat() and os.DirEntry.stat(): check for
exceptions. Previously, on Python built in debug mode, these
functions could trigger a fatal Python error (and abort the
process) when a function succeeded with an exception set. Patch
by Victor Stinner.
- gh-109375: The pdb alias command now prevents registering
aliases without arguments.
- gh-107219: Fix a race condition in concurrent.futures. When a
process in the process pool was terminated abruptly (while the
future was running or pending), close the connection write end.
If the call queue is blocked on sending bytes to a worker
process, closing the connection write end interrupts the send,
so the queue can be closed. Patch by Victor Stinner.
- gh-50644: Attempts to pickle or create a shallow or deep copy of
codecs streams now raise a TypeError. Previously, copying failed
with a RecursionError, while pickling produced wrong results
that eventually caused unpickling to fail with a RecursionError.
- gh-108987: Fix _thread.start_new_thread() race condition. If a
thread is created during Python finalization, the newly spawned
thread now exits immediately instead of trying to access freed
memory and lead to a crash. Patch by Victor Stinner.
- gh-108843: Fix an issue in ast.unparse() when unparsing
f-strings containing many quote types.
- gh-108682: Enum: raise TypeError if super().__new__() is called
from a custom __new__.
- gh-105829: Fix concurrent.futures.ProcessPoolExecutor deadlock
- gh-64662: Fix support for virtual tables in
sqlite3.Connection.iterdump(). Patch by Aviv Palivoda.
- gh-107913: Fix possible losses of errno and winerror values in
OSError exceptions if they were cleared or modified by the
cleanup code before creating the exception object.
- gh-104372: On Linux where subprocess can use the vfork() syscall
for faster spawning, prevent the parent process from blocking
other threads by dropping the GIL while it waits for the
vfork’ed child process exec() outcome. This prevents spawning a
binary from a slow filesystem from blocking the rest of the
application.
- gh-84867: unittest.TestLoader no longer loads test cases from
exact unittest.TestCase and unittest.FunctionTestCase classes.
- Documentation
- gh-109209: The minimum Sphinx version required for the
documentation is now 4.2.
- gh-105052: Update timeit doc to specify that time in seconds is
just the default.
- gh-102823: Document the return type of x // y when x and y have
type float.
- Tests
- gh-110031: Skip test_threading tests using thread+fork if Python
is built with Address Sanitizer (ASAN). Patch by Victor Stinner.
- gh-110088: Fix test_asyncio timeouts: don’t measure the maximum
duration, a test should not measure a CI performance. Only
measure the minimum duration when a task has a timeout or delay.
Add CLOCK_RES to test_asyncio.utils. Patch by Victor Stinner.
- gh-110033: Fix test_interprocess_signal() of test_signal. Make
sure that the subprocess.Popen object is deleted before the test
raising an exception in a signal handler. Otherwise,
Popen.__del__() can get the exception which is logged as
Exception ignored in: ... and the test fails. Patch by Victor
Stinner.
- gh-109594: Fix test_timeout() of
test_concurrent_futures.test_wait. Remove the future which may
or may not complete depending if it takes longer than the
timeout ot not. Keep the second future which does not complete
before wait() timeout. Patch by Victor Stinner.
- gh-109748: Fix test_zippath_from_non_installed_posix() of
test_venv: don’t copy __pycache__/ sub-directories, because they
can be modified by other Python tests running in parallel. Patch
by Victor Stinner.
- gh-103053: Skip test_freeze_simple_script() of
test_tools.test_freeze if Python is built with ./configure
- -enable-optimizations, which means with Profile Guided
Optimization (PGO): it just makes the test too slow. The freeze
tool is tested by many other CIs with other (faster) compiler
flags. Patch by Victor Stinner.
- gh-109396: Fix test_socket.test_hmac_sha1() in FIPS mode. Use a
longer key: FIPS mode requires at least of at least 112 bits.
The previous key was only 32 bits. Patch by Victor Stinner.
- gh-104736: Fix test_gdb on Python built with LLVM clang 16 on
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-109237: Fix test_site.test_underpth_basic() when the working
directory contains at least one non-ASCII character: encode the
._pth file to UTF-8 and enable the UTF-8 Mode to use UTF-8 for
the child process stdout. Patch by Victor Stinner.
- gh-109230: Fix test_pyexpat.test_exception(): it can now be run
from a directory different than Python source code directory.
Before, the test failed in this case. Skip the test if
Modules/pyexpat.c source is not available. Skip also the test on
Python implementations other than CPython. Patch by Victor
Stinner.
- gh-109015: Fix test_asyncio, test_imaplib and test_socket tests
on FreeBSD if the TCP blackhole is enabled (sysctl
net.inet.tcp.blackhole). Skip the few tests which failed with
ETIMEDOUT which such non standard configuration. Currently, the
FreeBSD GCP image enables TCP and UDP blackhole (sysctl
net.inet.tcp.blackhole=2 and sysctl net.inet.udp.blackhole=1).
Patch by Victor Stinner.
- gh-91960: Skip test_gdb if gdb is unable to retrieve Python
frame objects: if a frame is <optimized out>. When Python is
built with “clang -Og”, gdb can fail to retrive the frame
parameter of _PyEval_EvalFrameDefault(). In this case, tests
like py_bt() are likely to fail. Without getting access to
Python frames, python-gdb.py is mostly clueless on retrieving
the Python traceback. Moreover, test_gdb is no longer skipped on
macOS if Python is built with Clang. Patch by Victor Stinner.
- gh-108962: Skip test_tempfile.test_flags() if chflags() fails
with “OSError: [Errno 45] Operation not supported” (ex: on
FreeBSD 13). Patch by Victor Stinner.
- gh-89392: Removed support of test_main() function in tests. They
now always use normal unittest test runner.
- gh-108851: Fix test_tomllib recursion tests for WASI buildbots:
reduce the recursion limit and compute the maximum nested
array/dict depending on the current available recursion limit.
Patch by Victor Stinner.
- gh-108851: Add get_recursion_available() and
get_recursion_depth() functions to the test.support module.
Patch by Victor Stinner.
- gh-108822: regrtest now computes statistics on all tests:
successes, failures and skipped. test_netrc, test_pep646_syntax
and test_xml_etree now return results in their test_main()
function. Patch by Victor Stinner and Alex Waygood.
- gh-108388: Convert test_concurrent_futures to a package of 7
sub-tests. Patch by Victor Stinner.
- gh-108388: Split test_multiprocessing_fork,
test_multiprocessing_forkserver and test_multiprocessing_spawn
into test packages. Each package is made of 4 sub-tests:
processes, threads, manager and misc. It allows running more
tests in parallel and so reduce the total test duration. Patch
by Victor Stinner.
- gh-101634: When running the Python test suite with -jN option,
if a worker stdout cannot be decoded from the locale encoding
report a failed testn so the exitcode is non-zero. Patch by
Victor Stinner.
- gh-100086: The Python test runner (libregrtest) now logs Python
build information like “debug” vs “release” build, or LTO and
PGO optimizations. Patch by Victor Stinner.
- gh-98903: The Python test suite now fails wit exit code 4 if no
tests ran. It should help detecting typos in test names and test
methods.
- gh-95027: On Windows, when the Python test suite is run with the
- jN option, the ANSI code page is now used as the encoding for
the stdout temporary file, rather than using UTF-8 which can
lead to decoding errors. Patch by Victor Stinner.
- gh-93353: regrtest now checks if a test leaks temporary files or
directories if run with -jN option. Patch by Victor Stinner.
- Build
- gh-63760: Fix Solaris build: no longer redefine the
gethostname() function. Solaris defines the function since 2005.
Patch by Victor Stinner, original patch by Jakub Kulík.
- gh-108740: Fix a race condition in make regen-all. The
deepfreeze.c source and files generated by Argument Clinic are
now generated or updated before generating “global objects”.
Previously, some identifiers may miss depending on the order in
which these files were generated. Patch by Victor Stinner.
- Windows
- gh-109991: Update Windows build to use OpenSSL 3.0.11.
- gh-107565: Update Windows build to use OpenSSL 3.0.10.
- macOS
- gh-109991: Update macOS installer to use OpenSSL 3.0.11.
- Tools/Demos
- gh-109991: Update GitHub CI workflows to use OpenSSL 3.0.11 and
multissltests to use 1.1.1w, 3.0.11, and 3.1.3.
* Wed Sep 06 2023 daniel.garcia@suse.com
- Update to 3.11.5 (bsc#1214692):
- Security
- 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

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.

mmap.find() calls.
- gh-101006: Improve error handling when read marshal data.
- Library
- gh-105736: Harmonized the pure Python version of OrderedDict
with the C version. Now, both versions set up their internal
state in __new__. Formerly, the pure Python version did the set
up in __init__.
- gh-107963: Fix multiprocessing.set_forkserver_preload() to check
the given list of modules names. Patch by Dong-hee Na.
- gh-106242: Fixes os.path.normpath() to handle embedded null
characters without truncating the path (bsc#1214693,
CVE-2023-41105).
- gh-107845: tarfile.data_filter() now takes the location of
symlinks into account when determining their target, so it will
no longer reject some valid tarballs with
LinkOutsideDestinationError.
- gh-107715: Fix doctest.DocTestFinder.find() in presence of class
names with special characters. Patch by Gertjan van Zwieten.
- gh-100814: Passing a callable object as an option value to a
Tkinter image now raises the expected TclError instead of an
AttributeError.
- gh-106684: Close asyncio.StreamWriter when it is not closed by
application leading to memory leaks. Patch by Kumar Aditya.
- gh-107077: Seems that in some conditions, OpenSSL will return
SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL when a certification
verification has failed, but the error parameters will still
contain ERR_LIB_SSL and SSL_R_CERTIFICATE_VERIFY_FAILED. We are
now detecting this situation and raising the appropiate
ssl.SSLCertVerificationError. Patch by Pablo Galindo

shutil.make_archive(): do not create an empty archive if
root_dir is not a directory, and, in that case, raise
FileNotFoundError or NotADirectoryError regardless of format
choice. Beyond the brought-back behavior, the function may now
also raise these exceptions in dry_run mode.

if a worker stdout cannot be decoded from the locale encoding
report a failed testn so the exitcode is non-zero. Patch by
Victor Stinner.
- Build
- gh-107814: When calling find_python.bat with -q it did not
properly silence the output of nuget. That is now fixed.
- gh-106881: Check for linux/limits.h before including it in
Modules/posixmodule.c.
- gh-104692: Include commoninstall as a prerequisite for
bininstall
- This ensures that commoninstall is completed before bininstall
is started when parallel builds are used (make -j install), and
so the python3 symlink is only installed after all standard
library modules are installed.
- gh-100340: Allows -Wno-int-conversion for wasm-sdk 17 and
onwards, thus enables building WASI builds once against the
latest sdk.
- Windows
- gh-106242: Fixes realpath() to behave consistently when passed a
path containing an embedded null character on Windows. In strict
mode, it now raises OSError instead of the unexpected
ValueError, and in non-strict mode will make the path absolute.

OpenSSL 1.1.1v, 3.0.10, and 3.1.2.
- gh-95065: Argument Clinic now supports overriding automatically
generated signature by using directive @text_signature. See How
to override the generated signature.
- gh-106970: Fix bugs in the Argument Clinic destination <name>
clear command; the destination buffers would never be cleared,
and the destination directive parser would simply continue to
the fault handler after processing the command. Patch by Erlend
E. Aasland.
- C API
- gh-107916: C API functions PyErr_SetFromErrnoWithFilename(),
PyErr_SetExcFromWindowsErrWithFilename() and
PyErr_SetFromWindowsErrWithFilename() save now the error code
before calling PyUnicode_DecodeFSDefault().
- gh-107915: Such C API functions as PyErr_SetString(),
PyErr_Format(), PyErr_SetFromErrnoWithFilename() and many others
no longer crash or ignore errors if it failed to format the
error message or decode the filename. Instead, they keep a
corresponding error.
- gh-107226: PyModule_AddObjectRef() is now only available in the
limited API version 3.10 or later.
- gh-105375: Fix a bug in PyErr_WarnExplicit() where an exception
could end up being overwritten if the API failed internally.
- gh-99612: Fix PyUnicode_DecodeUTF8Stateful() for ASCII-only
data: *consumed was not set.
* Thu Aug 10 2023 dmueller@suse.com
- restrict PEP668 to ALP/Tumbleweed
* Fri Aug 04 2023 dmueller@suse.com
- add externally_managed.in to label this build as PEP-668 managed
* Thu Aug 03 2023 mcepl@suse.com
- IT MEANS THAT bsc#1210638 STILL HAS NOT BEEN FIXED!
- Add Revert-gh105127-left-tests.patch (gh#python/cpython!106941)
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).
* Wed Jun 28 2023 mcepl@suse.com
- Update to Python 3.11.4:
- 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).
- Remove upstreamed patches:
- CVE-2007-4559-filter-tarfile_extractall.patch
* Mon Jun 26 2023 mcepl@suse.com
- Remove obsolete_python_versioned macro again. This mechanism
has no business to be in Python 3.11, because we have abolished
with it whole interpreter+setuptools+pip product. Python 3.11
should not be replaced by later versions anymore.
* Sun Apr 30 2023 mcepl@suse.com
- Add 103213-fetch-CONFIG_ARGS.patch (gh#python/cpython#103053).
- Add skip_if_buildbot-extend.patch to avoid the bug altogether

providing Python 3.11 for SLE-15-SP4.
* Thu Dec 08 2022 mcepl@suse.com
- Update to 3.11.1:
- 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.
- Fix a reference bug in _imp.create_builtin() after the
creation of the first sub-interpreter for modules builtins
and sys. Patch by Victor Stinner.
- Fixed a bug that was causing a buffer overflow if the
tokenizer copies a line missing the newline caracter from a
file that is as long as the available tokenizer buffer. Patch
by Pablo galindo
- Fix bug where an ExceptionGroup subclass can wrap a
BaseException.
- Fix zip path for venv created from a non-installed python on
POSIX platforms.
- Fix an issue that could potentially cause incorrect error
handling for some bytecode instructions.
- Fix an issue that prevented PyThreadState and
PyInterpreterState memory from being freed properly.
- Fix failure in except* with unhashable exceptions.
- Fix calculation of sys._base_executable when inside a POSIX
virtual environment using copies of the python binary when
the base installation does not provide the executable name
used by the venv. Calculation will fall back to alternative
names (“python<MAJOR>”, “python<MAJOR>.<MINOR>”).
- Update faulthandler to emit an error message with the proper
unexpected signal number. Patch by Dong-hee Na.
- Fix location of SyntaxError for a try block with both except
and except*.
- Fix the error reporting positions of specialized traceback
anchors when the source line contains Unicode characters.
- Fix subscription of type aliases containing bare generic
types or types like TypeVar: for example tuple[A, T][int] and
tuple[TypeVar, T][int], where A is a generic type, and T is a
type variable.
- Lower the recursion depth for marshal on WASI to support
wasmtime 2.0/main.
- Fix multiple crashes in debug mode when str subclasses are
used instead of str itself.
- Fix an issue where member descriptors (such as those for
__slots__) could behave incorrectly or crash instead of
raising a TypeError when accessed via an instance of an
invalid type.
- Suppress ImportError for invalid query for help()
command. Patch by Dong-hee Na.
- Fix detection of MAC addresses for uuid on certain OSs. Patch
by Chaim Sanders
- Print exception class name instead of its string
representation when raising errors from ctypes calls.
- os.sched_yield() now release the GIL while calling
sched_yield(2). Patch by Dong-hee Na.
- Fix an issue that could delay the specialization of PRECALL
instructions.
- Bugfix: PyFunction_GetAnnotations() should return a borrowed
reference. It was returning a new reference.
- Ensure that all Python frame objects are backed by “complete”
frames.
- Fixed a missing incref/decref pair in
Exception.__setstate__(). Patch by Ofey Chan.
- Fix the Python path configuration used to initialized
sys.path at Python startup. Paths are no longer encoded
to UTF-8/strict to avoid encoding errors if it contains
surrogate characters (bytes paths are decoded with the
surrogateescape error handler). Patch by Victor Stinner.
- Fix overly-broad source position information for chained
comparisons used as branching conditions.
- At Python exit, sometimes a thread holding the GIL can
wait forever for a thread (usually a daemon thread) which
requested to drop the GIL, whereas the thread already
exited. To fix the race condition, the thread which requested
the GIL drop now resets its request before exiting. Issue
discovered and analyzed by Mingliang ZHAO. Patch by Victor
Stinner.
- Fix a possible assertion failure, fatal error, or SystemError
if a line tracing event raises an exception while opcode
tracing is enabled.
- Fix undefined behaviour in C code of null pointer arithmetic.
- Make sure that all frame objects created are created from
valid interpreter frames. Prevents the possibility of invalid
frames in backtraces and signal handlers.
- Disable incorrect pickling of the C implemented classmethod
descriptors.
- On WASI ENOTCAPABLE is now mapped to PermissionError. The
errno modules exposes the new error number. getpath.py now
ignores PermissionError when it cannot open landmark files
pybuilddir.txt and pyenv.cfg.
- Allow pdb to locate source for frozen modules in the standard
library.
- Raise ValueError instead of SystemError when methods of
uninitialized io.IncrementalNewlineDecoder objects are
called. Patch by Oren Milman.
- Fix a possible assertion failure in io.FileIO when the opener
returns an invalid file descriptor.
- Also escape s in the http.server
BaseHTTPRequestHandler.log_message so that it is technically
possible to parse the line and reconstruct what the original
data was. Without this a xHH is ambiguious as to if it is a
hex replacement we put in or the characters r”x” came through
in the original request line.
- asyncio.get_event_loop() now only emits a deprecation warning
when a new event loop was created implicitly. It no longer
emits a deprecation warning if the current event loop was
set.
- Fix bug when calling trace.CoverageResults with valid infile.
- Fix a bug in handling class cleanups in
unittest.TestCase. Now addClassCleanup() uses separate lists
for different TestCase subclasses, and doClassCleanups() only
cleans up the particular class.
- Release the GIL when calling termios APIs to avoid blocking
threads.
- Fix ast.increment_lineno() to also cover ast.TypeIgnore when
changing line numbers.
- Fix bug in urllib.parse.urlparse() that causes URL schemes
that begin with a digit, a plus sign, or a minus sign to be
parsed incorrectly.
- Check the number of arguments in substitution in user
generics containing a TypeVarTuple and one or more TypeVar.
- Fix substitution of ParamSpec followed by TypeVarTuple in
generic aliases.
- Fix substitution of TypeVarTuple and ParamSpec together in
user generics.
- Fixed bug where inspect.signature() reported incorrect
arguments for decorated methods.
- Fix SystemError in ctypes when exception was not set during
__initsubclass__.
- Remove older version of
_SSLProtocolTransport.get_write_buffer_limits in
asyncio.sslproto
- fix negative numbers failing in verify()
- Fix statistics.NormalDist pickle with 0 and 1 protocols.
- enum.auto() is now correctly activated when combined with
other assignment values. E.g. ONE = auto(), 'some text' will
now evaluate as (1, 'some text').
- Update the bundled copy of pip to version 22.3.1.
- Clean up refleak on failed module initialisation in _zoneinfo
- Clean up refleaks on failed module initialisation in in
_pickle
- Clean up refleak on failed module initialisation in _io.
- Fix memory leak in math.dist() when both points don’t have
the same dimension. Patch by Kumar Aditya.
- [3.11] Applied changes from importlib_metadata 4.11.4
through 4.13, including compatibility and robustness
fixes for Distribution objects without _normalized_name,
disallowing invalid inputs to Distribution.from_name, and
refined behaviors in PathDistribution._name_from_stem and
PathDistribution._normalized_name.
- Fix argument typechecks in _overlapped.WSAConnect() and
_overlapped.Overlapped.WSASendTo() functions.
- Prevent crashing in traceback when retrieving the byte-offset
for some source files that contain certain unicode
characters.
- Fix internal error in the re module which in very rare
circumstances prevented compilation of a regular expression
containing a conditional expression without the “else”
branch.
- Fix asyncio.StreamWriter.drain() to call
protocol.connection_lost callback only once on Windows.
- Add a mutex to unittest.mock.NonCallableMock to protect
concurrent access to mock attributes.
- Fix hang on Windows in subprocess.wait_closed() in asyncio
with ProactorEventLoop. Patch by Kumar Aditya.
- Fix infinite loop in unittest when a self-referencing chained
exception is raised
- tkinter.Text.count() raises now an exception for options
starting with “-” instead of silently ignoring them.
- On uname_result, restored expectation that _fields and
_asdict would include all six properties including processor.
- A createSocket() method was added to SysLogHandler.
- Fix bug in urllib.parse.urlparse() that causes certain port
numbers containing whitespace, underscores, plus and minus
signs, or non-ASCII digits to be incorrectly accepted.
- Allow venv to pass along PYTHON* variables to ensurepip and
pip when they do not impact path resolution
- On macOS, fix a crash in syslog.syslog() in multi-threaded
applications. On macOS, the libc syslog() function is not
thread-safe, so syslog.syslog() no longer releases the GIL to
call it. Patch by Victor Stinner.
- Allow BUILTINS to be a valid field name for frozen
dataclasses.
- Wrap network errors consistently in urllib FTP support, so
the test suite doesn’t fail when a network is available but
the public internet is not reachable.
- Make sure patch.dict() can be applied on async functions.
- Earlier in 3.11 we deprecated
asyncio.Task.cancel("message"). We realized we were too
harsh, and have undeprecated it.
- Change deprecate warning message in unittest from It is
deprecated to return a value!=None to It is deprecated to
return a value that is not None from a test case
- Fixes AttributeError when subprocess.check_output() is used
with argument input=None and either of the arguments encoding
or errors are used.
- Fix is_private properties in the ipaddress module. Previously
non-private networks (0.0.0.0/0) would return True from this
method; now they correctly return False.
- Avoid spurious tracebacks from asyncio when default executor
cleanup is delayed until after the event loop is closed (e.g.
as the result of a keyboard interrupt).
- Avoid a crash in the C version of
asyncio.Future.remove_done_callback() when an evil argument
is passed.
- Remove tokenize.NL check from tabnanny.
- Fix generation of the default name of
tkinter.Checkbutton. Previously, checkbuttons in different
parent widgets could have the same short name and share
the same state if arguments “name” and “variable” are not
specified. Now they are globally unique.
- Update bundled libexpat to 2.4.9
- Fix race condition in asyncio where process_exited() called
before the pipe_data_received() leading to inconsistent
output. Patch by Kumar Aditya.
- Fixed check in multiprocessing.resource_tracker that
guarantees that the length of a write to a pipe is not
greater than PIPE_BUF.
- Corrected type annotation for dataclass attribute
pstats.FunctionProfile.ncalls to be str.
- Fix repr of Any subclasses.
- Work around missing socket functions in socket’s __repr__.
- In inspect, fix overeager replacement of “typing.” in
formatting annotations.
- Fix handling of bytes path-like objects in os.ismount().
- Fix handling compiler warnings (SyntaxWarning and
DeprecationWarning) in codeop.compile_command() when checking
for incomplete input. Previously it emitted warnings and
raised a SyntaxError. Now it always returns None for
incomplete input without emitting any warnings.
- To avoid apparent memory leaks when asyncio.open_connection()
raises, break reference cycles generated by local exception
and future instances (which has exception instance as its
member var). Patch by Dong Uk, Kang.
- Fixed flickering of the turtle window when the tracer is
turned off. Patch by Shin-myoung-serp.
- Fix asyncio subprocess transport to kill process cleanly
when process is blocked and avoid RuntimeError when loop is
closed. Patch by Kumar Aditya.
- Prevent error when activating venv in nested fish instances.
- TarFile.next() now returns None when called on an empty
tarfile.
- Document the optional callback parameter of WeakMethod. Patch
by Géry Ogam.
- Restrict use of sockets instead of pipes for stdin of
subprocesses created by asyncio to AIX platform only.
- shutil.copytree() now applies the ignore_dangling_symlinks
argument recursively.
- Fix IndexError in argparse.ArgumentParser when a store_true
action is given an explicit argument.
- Document that calling variadic functions with ctypes requires
special care on macOS/arm64 (and possibly other platforms).
- Remove extra row
- Clarified the conflicting advice given in the ast
documentation about ast.literal_eval() being “safe” for use
on untrusted input while at the same time warning that it
can crash the process. The latter statement is true and is
deemed unfixable without a large amount of work unsuitable
for a bugfix. So we keep the warning and no longer claim that
literal_eval is safe.
- Restructured the documentation for the os.wait* family of
functions, and improved the docs for os.waitid() with more
explanation of the possible argument constants.
- Skip test_normalization() of test_unicodedata if it
fails to download NormalizationTest.txt file from
pythontest.net. Patch by Victor Stinner.
- Correct test_marsh on (32 bit) x86: test_deterministic sets
was failing.
- Optional big memory tests in test_sqlite3 now catch the
correct sqlite.DataError exception type in case of too large
strings and/or blobs passed.
- Fix a bug in the typing tests where a test relying
on CPython-specific implementation details was not
decorated with @cpython_only and was not skipped on other
implementations.
- Add tests for star-unpacking with PEP 646, and some other
miscellaneous PEP 646 tests.
- Added explicit coverage of Py_Initialize (and hence
Py_InitializeEx) back to the embedding tests (all other
embedding tests migrated to Py_InitializeFromConfig in Python
3.11)
- Some C API tests were moved into the new Lib/test/test_capi/
directory.
- Fix -Wimplicit-int, -Wstrict-prototypes, and
- Wimplicit-function-declaration compiler warnings in
configure checks.
- Fix a compilation issue with GCC 12 on macOS.
- Fix -Wimplicit-int compiler warning in configure check for
PTHREAD_SCOPE_SYSTEM.
- Fix a possible fd leak in Programs/_freeze_module.c
introduced in Python 3.11.
- Fix build with PYTHON_FOR_REGEN=python3.8.
- Specify the full path to the source location for make
docclean (needed for cross-builds).
- Don’t use vendored libmpdec headers if --with-system-libmpdec
is passed to configure. Don’t use vendored libexpat headers
if --with-system-expat is passed to !configure.
- Fix the build process of clang compiler for _bootstrap_python
if LTO optimization is applied. Patch by Matthias Görgens and
Dong-hee Na.
- wasm32-emscripten builds for browsers now include
concurrent.futures for asyncio and unittest.mock.
- wasm32-emscripten platform no longer builds resource module,
getresuid(), getresgid(), and their setters. The APIs are
stubs and not functional.
- Updated pegen regeneration script on Windows to find and
use Python 3.9 or higher. Prior to this, pegen regeneration
already required 3.9 or higher, but the script may have used
lower versions of Python.
- Fix a bug in the previous bugfix that caused IDLE to
not start when run with 3.10.8, 3.12.0a1, and at least
Microsoft Python 3.10.2288.0 installed without the Lib/test
package. 3.11.0 was never affected.
- The wasm_build.py script now pre-builds Emscripten ports,
checks for broken EMSDK versions, and warns about pkg-config
env vars.
- The new tool Tools/wasm/wasm_builder.py automates configure,
compile, and test steps for building CPython on WebAssembly
platforms.
- Fix handling of module docstrings in Tools/i18n/pygettext.py.
- PyBUF_* constants were marked as part of Limited API
of Python 3.11+. These were available in 3.11.0 with
Py_LIMITED_API defined for 3.11, and are necessary to use the
buffer API.
- Fix use-after-free in Py_SetPythonHome(NULL),
Py_SetProgramName(NULL) and _Py_SetProgramFullPath(NULL)
function calls. Issue reported by Benedikt Reinartz. Patch by
Victor Stinner.
- Py_InitializeEx now correctly calls PyConfig_Clear after
initializing the interpreter (the omission didn’t cause a
memory leak only because none of the dynamically allocated
config fields are populated by the wrapper function)
- Removed upstreamed patches:
- 98437-sphinx.locale._-as-gettext-in-pyspecific.patch
- CVE-2022-45061-DoS-by-IDNA-decode.patch
* Wed Nov 09 2022 mcepl@suse.com
- Add CVE-2022-45061-DoS-by-IDNA-decode.patch to avoid
CVE-2022-45061 (bsc#1205244) allowing DoS by IDNA decoding
extremely long domain names.
* Tue Oct 25 2022 mcepl@suse.com
- 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.
- On Linux the multiprocessing module returns to using
filesystem backed unix domain sockets for communication
with the forkserver process instead of the Linux abstract
socket namespace. Only code that chooses to use the
“forkserver” start method is affected. Abstract sockets have
no permissions and could allow any user on the system in the
same network namespace (often the whole system) to inject
code into the multiprocessing forkserver process. This was
a potential privilege escalation. Filesystem based socket
permissions restrict this to the forkserver process user as
was the default in Python 3.8 and earlier. This prevents
Linux CVE-2022-42919.
- Fix an issue where several frame objects could be backed by
the same interpreter frame, possibly leading to corrupted
memory and hard crashes of the interpreter.
- Fix possible data corruption or crashes when accessing the
f_back member of newly-created generator or coroutine frames.
- Fix a crash occurring when PyEval_GetFrame() is called while
the topmost Python frame is in a partially-initialized state.
- Fix command line parsing: reject -X int_max_str_digits option
with no value (invalid) when the PYTHONINTMAXSTRDIGITS
environment variable is set to a valid limit. Patch by Victor
Stinner.
- Fix undefined behaviour in _testcapimodule.c.
- When ValueError is raised if an integer is larger than the
limit, mention the sys.set_int_max_str_digits() function in
the error message. Patch by Victor Stinner.
- Correctly raise SyntaxError on exception groups (PEP 654) on
python versions prior to 3.11
- Document some places where an assignment expression needs
parentheses.
- Update the bundled copies of pip and setuptools to versions
22.3 and 65.5.0 respectively.
- fix Flag to use boundary CONFORM
- This restores previous Flag behavior of allowing flags with
non-sequential values to be combined; e.g.
- class Skip(Flag): TWO = 2 EIGHT = 8
- Skip.TWO | Skip.EIGHT -> <Skip.TWO|EIGHT: 10>
- Fix ! in c domain ref target syntax via a conf.py patch, so
it works as intended to disable ref target resolution.
- Update tutorial introduction output to use 3.10+ SyntaxError
invalid range.
* Fri Oct 21 2022 mcepl@suse.com
- Add 98437-sphinx.locale._-as-gettext-in-pyspecific.patch to
allow building of documentation with the latest Sphinx 5.3.0
(gh#python/cpython#98366).
* Thu Sep 15 2022 mcepl@suse.com
- Update to 3.11.0rc2:
- 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.
- Loading a file with invalid UTF-8 will now report the broken
character at the correct location.
- Fixed a bug that caused _PyCode_GetExtra to return garbage
for negative indexes. Patch by Pablo Galindo
- Fix a deadlock in PyGILState_Ensure() when allocating new
thread state. Patch by Kumar Aditya.
- PyType_Ready() now initializes ht_cached_keys and performs

configured. This avoids crashes in 3rd party packages that
don’t use regular API to create new types.
- Skip over incomplete frames in PyThreadState_GetFrame().
- Fix format string in _PyPegen_raise_error_known_location that
can lead to memory corruption on some 64bit systems. The
function was building a tuple with i (int) instead of n
(Py_ssize_t) for Py_ssize_t arguments.

- Fix TypeVarTuple.__typing_prepare_subst__. TypeError was not
raised when using more than one TypeVarTuple, like [*T, *V]
in type alias substitutions.
- Fix asyncio.streams.StreamReaderProtocol to keep a strong
reference to the created task, so that it’s not garbage
collected
- Fix a performance regression in logging
TimedRotatingFileHandler. Only check for special files when
the rollover time has passed.
- Fix unused localName parameter in the Attr class in
xml.dom.minidom.
- Fix incorrect condition that causes sys.thread_info.name to
be wrong on pthread platforms.
- Remove an incompatible change from bpo-28080 that caused a
regression that ignored the utf8 in ZipInfo.flag_bits. Patch
by Pablo Galindo.

once to avoid calling attach_loop() multiple times on child
watchers. Patch by Kumar Aditya.
- Fix unittest.IsolatedAsyncioTestCase to set event loop before
calling setup functions. Patch by Kumar Aditya.
- When a task catches asyncio.CancelledError and raises some
other error, the other error should generally not silently be
suppressed.
- Fail gracefully if EPERM or ENOSYS is raised when loading
crypt methods. This may happen when trying to load MD5 on a
Linux kernel with FIPS enabled.
- Allow asyncio.StreamWriter.drain() to be awaited concurrently
by multiple tasks. Patch by Kumar Aditya.
- Fix ast.unparse() when ImportFrom.level is None
- Improve discoverability of the higher level

compile() and other related functions. If invalid positions
are detected, a ValueError will be raised.
- Fix error detection in some builtin functions when keyword
argument name is an instance of a str subclass with
overloaded __eq__ and __hash__. Previously it could cause
SystemError or other undesired behavior.
- Library

handler is executed before any handlers in atexit.
- Tests
- Lib/test/test_asyncio/test_ssl.py exposed a bug in the
macOS kernel where intense concurrent load on non-blocking
sockets occasionally causes errno.ENOBUFS (“No buffer space
available”) to be emitted. FB11063974 filed with Apple, in
the mean time as a workaround buffer size used in tests on
macOS is decreased to avoid intermittent failures. Patch by
Fantix King.

sequences in f-strings.
- bpo-46417: Fix a race condition on setting a type __bases__
attribute: the internal function add_subclass() now gets the
PyTypeObject.tp_subclasses member after calling
PyWeakref_NewRef() which can trigger a garbage collection
which can indirectly modify PyTypeObject.tp_subclasses. Patch
by Victor Stinner.

22.0.4)
- bpo-46968: faulthandler: On Linux 5.14 and newer, dynamically
determine size of signal handler stack size CPython allocates
using getauxval(AT_MINSIGSTKSZ). This changes allows for
Python extension’s request to Linux kernel to use AMX_TILE
instruction set on Sapphire Rapids Xeon processor to succeed,
unblocking use of the ISA in frameworks.
- bpo-46955: Expose asyncio.base_events.Server as
asyncio.Server. Patch by Stefan Zabka.

of arguments.
- bpo-14156: argparse.FileType now supports an argument of ‘-’
in binary mode, returning the .buffer attribute of
sys.stdin/sys.stdout as appropriate. Modes including ‘x’ and
‘a’ are treated equivalently to ‘w’ when argument is ‘-’.

modify these tests to use support.infinite_recursion(). Patch
by Victor Stinner.
- bpo-13886: Skip test_builtin PTY tests on non-ASCII
characters if the readline module is loaded. The readline
module changes input() behavior, but test_builtin is not
intented to test the readline module. Patch by Victor
Stinner.
- bpo-38472: Fix GCC detection in setup.py when
cross-compiling. The C compiler is now run with LC_ALL=C.
Previously, the detection failed with a German locale.
- bpo-46513: configure no longer uses AC_C_CHAR_UNSIGNED macro
and pyconfig.h no longer defines reserved symbol
__CHAR_UNSIGNED__.

menu, ‘Close’ and ‘Exit’ are now ‘Close Window’ (the current
one) and ‘Exit’ is now ‘Exit IDLE’ (by closing all windows).
In Shell, ‘quit()’ and ‘exit()’ mean ‘close Shell’. If there
are no other windows, this also exits IDLE.
- bpo-45447: Apply IDLE syntax highlighting to pyi files. Patch
by Alex Waygood and Terry Jan Reedy.
- bpo-46433: The internal function _PyType_GetModuleByDef now
correctly handles inheritance patterns involving static

- Update to 3.9.5:
* Security
- bpo-43434: Creating a sqlite3.Connection object now also
produces a sqlite3.connect auditing event. Previously this
event was only produced by sqlite3.connect() calls. Patch
by Erlend E. Aasland.
- bpo-43882: The presence of newline or tab characters in
parts of a URL could allow some forms of attacks.
- Following the controlling specification for URLs defined by
WHATWG urllib.parse() now removes ASCII newlines and tabs
from URLs, preventing such attacks.
- bpo-43472: Ensures interpreter-level audit hooks receive
the cpython.PyInterpreterState_New event when called
through the _xxsubinterpreters module.
- bpo-36384: ipaddress module no longer accepts any leading
zeros in IPv4 address strings. Leading zeros are ambiguous
and interpreted as octal notation by some libraries. For
example the legacy function socket.inet_aton() treats
leading zeros as octal notatation. glibc implementation of
modern inet_pton() does not accept any leading zeros. For
a while the ipaddress module used to accept ambiguous
leading zeros.
- bpo-43075: Fix Regular Expression Denial of Service (ReDoS)
vulnerability in urllib.request.AbstractBasicAuthHandler.
The ReDoS-vulnerable regex has quadratic worst-case
complexity and it allows cause a denial of service when
identifying crafted invalid RFCs. This ReDoS issue is on
the client side and needs remote attackers to control the
HTTP server.
- bpo-42800: Audit hooks are now fired for frame.f_code,
traceback.tb_frame, and generator code/frame attribute
access.
* Core and Builtins
- bpo-43105: Importlib now resolves relative paths when
creating module spec objects from file locations.
- bpo-42924: Fix bytearray repetition incorrectly copying
data from the start of the buffer, even if the data is
offset within the buffer (e.g. after reassigning a slice at
the start of the bytearray to a shorter byte string).
* Library
- bpo-43993: Update bundled pip to 21.1.1.
- bpo-43937: Fixed the turtle module working with non-default
root window.
- bpo-43930: Update bundled pip to 21.1 and setuptools to
56.0.0
- bpo-43920: OpenSSL 3.0.0: load_verify_locations() now
returns a consistent error message when cadata contains no
valid certificate.
- bpo-43607: urllib can now convert Windows paths with \\?\
prefixes into URL paths.
- bpo-43284: platform.win32_ver derives the windows version
from sys.getwindowsversion().platform_version which in turn
derives the version from kernel32.dll (which can be of
a different version than Windows itself). Therefore change
the platform.win32_ver to determine the version using the
platform module’s _syscmd_ver private function to return an
accurate version.
- bpo-42248: [Enum] ensure exceptions raised in _missing__
are released
- bpo-43799: OpenSSL 3.0.0: define OPENSSL_API_COMPAT 1.1.1
to suppress deprecation warnings. Python requires OpenSSL
1.1.1 APIs.
- bpo-43794: Add ssl.OP_IGNORE_UNEXPECTED_EOF constants
(OpenSSL 3.0.0)
- bpo-43789: OpenSSL 3.0.0: Don’t call the password callback
function a second time when first call has signaled an
error condition.
- bpo-43788: The header files for ssl error codes are now
OpenSSL version-specific. Exceptions will now show correct
reason and library codes. The make_ssl_data.py script has
been rewritten to use OpenSSL’s text file with error codes.
- bpo-43655: tkinter dialog windows are now recognized as
dialogs by window managers on macOS and X Window.
- bpo-43534: turtle.textinput() and turtle.numinput() create
now a transient window working on behalf of the canvas
window.
- bpo-43522: Fix problem with hostname_checks_common_name.
OpenSSL does not copy hostflags from struct SSL_CTX to
struct SSL.
- bpo-42967: Allow bytes separator argument in
urllib.parse.parse_qs and urllib.parse.parse_qsl when
parsing str query strings. Previously, this raised
a TypeError.
- bpo-43176: Fixed processing of a dataclass that inherits
from a frozen dataclass with no fields. It is now correctly
detected as an error.
- bpo-41735: Fix thread locks in zlib module may go wrong in
rare case. Patch by Ma Lin.
- bpo-36470: Fix dataclasses with InitVars and replace().
Patch by Claudiu Popa.
- bpo-32745: Fix a regression in the handling of ctypes’
ctypes.c_wchar_p type: embedded null characters would cause
a ValueError to be raised. Patch by Zackery Spytz.
* Documentation
- bpo-43959: The documentation on the PyContextVar C-API was
clarified.
- bpo-43938: Update dataclasses documentation to express that
FrozenInstanceError is derived from AttributeError.
- bpo-43755: Update documentation to reflect that
unparenthesized lambda expressions can no longer be the
expression part in an if clause in comprehensions and
generator expressions since Python 3.9.
- bpo-43739: Fixing the example code in
Doc/extending/extending.rst to declare and initialize the
pmodule variable to be of the right type.
* Tests
- bpo-43961: Fix
test_logging.test_namer_rotator_inheritance() on Windows:
use os.replace() rather than os.rename(). Patch by Victor
Stinner.
- bpo-43842: Fix a race condition in the SMTP test of
test_logging. Don’t close a file descriptor (socket) from
a different thread while asyncore.loop() is polling the
file descriptor. Patch by Victor Stinner.
- bpo-43811: Tests multiple OpenSSL versions on GitHub
Actions. Use ccache to speed up testing.
- bpo-43791: OpenSSL 3.0.0: Disable testing of legacy
protocols TLS 1.0 and 1.1. Tests are failing with
TLSV1_ALERT_INTERNAL_ERROR.
- Refreshed patches:
- bpo-31046_ensurepip_honours_prefix.patch
- python-3.3.0b1-fix_date_time_compiler.patch
- Add vendorized files from bluez-devel to enable building support for
Bluetooth.
* Sun May 02 2021 code@bnavigator.de
- Make sure to close the import_failed.map file after the exception
has been raised in order to avoid ResourceWarnings when the
failing import is part of a try...except block.
* Wed Apr 28 2021 mcepl@suse.com
- Update to 3.9.4:
- bpo#43710: Reverted the fix for https://bugs.python.org/issue42500
as it changed the PyThreadState struct size and broke the 3.9.x ABI
in the 3.9.3 release (visible on 32-bit platforms using binaries
compiled using an earlier version of Python 3.9.x headers).
- bpo#26053: Fixed bug where the pdb interactive run command echoed
the args from the shell command line, even if those have been
overridden at the pdb prompt.
- bpo#42988 (bsc#1183374) CVE-2021-3426: Remove the getfile
feature of the pydoc module which could be abused to read
arbitrary files on the disk (directory traversal
vulnerability). Moreover, even source code of Python modules
can contain sensitive data like passwords. Vulnerability
reported by David Schwörer.
- bpo#43285: ftplib no longer trusts the IP address value
returned from the server in response to the PASV command by
default. This prevents a malicious FTP server from using the
response to probe IPv4 address and port combinations on the
client network. Code that requires the former vulnerable
behavior may set a trust_server_pasv_ipv4_address attribute
on their ftplib.FTP instances to True to re-enable it.
- bpo#43439: Add audit hooks for gc.get_objects(),
gc.get_referrers() and gc.get_referents(). Patch by Pablo
Galindo.
- bpo#43660: Fix crash that happens when replacing sys.stderr
with a callable that can remove the object while an exception
is being printed. Patch by Pablo Galindo.
- bpo#43555: Report the column offset for SyntaxError for
invalid line continuation characters. Patch by Pablo Galindo.
- bpo#43517: Fix misdetection of circular imports when using
from pkg.mod import attr, which caused false positives in
non-trivial multi-threaded code.
- bpo#35883: Python no longer fails at startup with a fatal
error if a command line argument contains an invalid Unicode
character. The Py_DecodeLocale() function now escapes byte
sequences which would be decoded as Unicode characters
outside the [U+0000; U+10ffff] range.
- bpo#43406: Fix a possible race condition where
PyErr_CheckSignals tries to execute a non-Python signal
handler.
- bpo#42500: Improve handling of exceptions near recursion
limit. Converts a number of Fatal Errors in RecursionErrors.
- bpo#43433: xmlrpc.client.ServerProxy no longer ignores query
and fragment in the URL of the server.
- bpo#35930: Raising an exception raised in a “future” instance
will create reference cycles.
- bpo#43577: Fix deadlock when using ssl.SSLContext debug
callback with ssl.SSLContext.sni_callback().
- bpo#43521: ast.unparse can now render NaNs and empty sets.
- bpo#43423: subprocess.communicate() no longer raises an
IndexError when there is an empty stdout or stderr IO buffer
during a timeout on Windows.
- bpo#27820: Fixed long-standing bug of smtplib.SMTP where
doing AUTH LOGIN with initial_response_ok=False will fail.
The cause is that SMTP.auth_login _always_ returns a password
if provided with a challenge string, thus non-compliant with
the standard for AUTH LOGIN. Also fixes bug with the test for
smtpd.
- bpo#43332: Improves the networking efficiency of http.client
when using a proxy via set_tunnel(). Fewer small send calls
are made during connection setup.
- bpo#43399: Fix ElementTree.extend not working on iterators
when using the Python implementation
- bpo#43316: The python -m gzip command line application now
properly fails when detecting an unsupported extension. It
exits with a non-zero exit code and prints an error message
to stderr.
- bpo#43260: Fix TextIOWrapper can not flush internal buffer
forever after very large text is written.
- bpo#42782: Fail fast in shutil.move() to avoid creating
destination directories on failure.
- bpo#37193: Fixed memory leak in socketserver.ThreadingMixIn
introduced in Python 3.7.
- bpo#43199: Answer “Why is there no goto?” in the Design and
History FAQ.
- bpo#43407: Clarified that a result from time.monotonic(),
time.perf_counter(), time.process_time(), or
time.thread_time() can be compared with the result from any
following call to the same function - not just the next
immediate call.
- bpo#27646: Clarify that ‘yield from <expr>’ works with any
iterable, not just iterators.
- bpo#36346: Update some deprecated unicode APIs which are
documented as “will be removed in 4.0” to “3.12”. See PEP 623
for detail.
- bpo#37945: Fix test_getsetlocale_issue1813() of test_locale:
skip the test if setlocale() fails. Patch by Victor Stinner.
- bpo#41561: Add workaround for Ubuntu’s custom OpenSSL
security level policy.
- bpo#43288: Fix test_importlib to correctly skip Unicode file
tests if the fileystem does not support them.
- bpo#43617: Improve configure.ac: Check for presence of
autoconf-archive package and remove our copies of M4 macros.
- bpo#42225: Document that IDLE can fail on Unix either from
misconfigured IP masquerage rules or failure displaying
complex colored (non-ascii) characters.
- bpo#43283: Document why printing to IDLE’s Shell is often
slower than printing to a system terminal and that it can be
made faster by pre-formatting a single string before
printing.
* Fri Feb 19 2021 mcepl@suse.com
- Update to 3.9.2:
- bpo#42938 (bsc#1181126): Avoid static buffers when computing
the repr of ctypes.c_double and ctypes.c_longdouble
values. This issue was assigned CVE-2021-3177.
- bpo#42967 (bsc#1182379): Fix web cache poisoning
vulnerability by defaulting the query args separator to &,
and allowing the user to choose a custom separator. This
issue was assigned CVE-2021-23336.
- Upstreamed patches were removed:
- CVE-2021-3177-buf_ovrfl_PyCArg_repr.patch

- Add Obsoletes for python3-base when primary interpreter is set to
properly replace it during upgrades. (bsc#1181324)
* Mon Feb 08 2021 mcepl@suse.com
- Update to 3.9.1:
Security bugs:
- Prevented potential DoS attack via CPU and RAM exhaustion
when processing malformed Apple Property List files in binary
format.
- The plistlib module no longer accepts entity declarations in
XML plist files to avoid XML vulnerabilities. This should not
affect users as entity declarations are not used in regular
plist files.
- Add volatile to the accumulator variable in
hmac.compare_digest, making constant-time-defeating
optimizations less likely.
Core and Builtins
- Allow assignment expressions in set literals and set
comprehensions as per PEP 572. Patch by Pablo Galindo.
- Fix a regression introduced by the new parser, where an
unparenthesized walrus operator was not allowed within
generator expressions.
- types.GenericAlias objects can now be the targets of
weakrefs.
- Fixed a bug in the PEG parser that was causing crashes in
debug mode. Now errors are checked in left-recursive rules to
avoid cases where such errors do not get handled in time and
appear as long-distance crashes in other places.
- Fixed a possible crash in the PEG parser when checking for
the ‘!=’ token in the barry_as_flufl rule. Patch by Pablo
Galindo.
- Fix handling of errors during creation of PyFunctionObject,
which resulted in operations on uninitialized memory. Patch
by Yonatan Goldschmidt.
- Fix a bug in the parser, where a curly brace following
a primary didn’t fail immediately. This led to invalid
expressions like a {b} to throw a SyntaxError with a wrong
offset, or invalid expressions ending with a curly brace like
a { to not fail immediately in the REPL.
- Fix possible buffer overflow in the new parser when checking
for continuation lines. Patch by Pablo Galindo.
- Run the parser two times. On the first run, disable all the
rules that only generate better error messages to gain
performance. If there’s a parse failure, run the parser
a second time with those enabled.
- Document the default implementation of object.__eq__.
- Fix peephole optimizer misoptimize conditional jump
+ JUMP_IF_NOT_EXC_MATCH pair.
- The garbage collector now tracks all user-defined classes.
Patch by Brandt Bucher.
- Fixed potential issues with removing not completely
initialized module from sys.modules when import fails.
- Star-unpacking is now allowed for with item’s targets in the
PEG parser.
- Fixed stack overflow in issubclass() and isinstance() when
getting the __bases__ attribute leads to infinite recursion.
- When loading a native module and a load failure occurs,
prevent a possible UnicodeDecodeError when not running in
a UTF-8 locale by decoding the load error message using the
current locale’s encoding.
- Correctly count control blocks in ‘except’ in compiler.
Ensures that a syntax error, rather a fatal error, occurs for
deeply nested, named exception handlers.
Library
- types.GenericAlias will now raise a TypeError when attempting
to initialize with a keyword argument. Previously, this would
cause the interpreter to crash if the interpreter was
compiled with debug symbols. This does not affect
interpreters compiled for release. Patch by Ken Jin.
- CGIHTTPRequestHandler.run_cgi() HTTP_ACCEPT improperly
parsed. Replace the special purpose getallmatchingheaders
with generic get_all method and add relevant tests.
- inspect.findsource() now raises OSError instead of IndexError
when co_lineno of a code object is greater than the file
length. This can happen, for example, when a file is edited
after it was imported. PR by Irit Katriel.
- Fix handling of trailing comments by inspect.getsource().
- ChainMap.__iter__ no longer calls __getitem__ on underlying
maps
- TracebackException no longer holds a reference to the
exception’s traceback object. Consequently, instances of
TracebackException for equivalent but non-equal exceptions
now compare as equal.
- We fixed an issue in pickle.whichmodule in which importing
multiprocessing could change the how pickle identifies which
module an object belongs to, potentially breaking the
unpickling of those objects.
- Clarify the error message for asyncio.IncompleteReadError
when expected is None.
- Extracting a symlink from a tarball should succeed and
overwrite the symlink if it already exists. The fix is to
remove the existing file or symlink before extraction. Based
on patch by Chris AtLee, Jeffrey Kintscher, and Senthil
Kumaran.
- Fixed tkinter.ttk.Style.map(). The function accepts now the
representation of the default state as empty sequence (as
returned by Style.map()). The structure of the result is now
the same on all platform and does not depend on the value of
wantobjects.
- Fix various issues with typing.Literal parameter handling
(flatten, deduplicate, use type to cache key). Patch provided
by Yurii Karabas.
- Fix the threading.Thread class at fork: do nothing if the
thread is already stopped (ex: fork called at Python exit).
Previously, an error was logged in the child process.
- The onerror callback from shutil.rmtree now receives correct
function when os.open fails.
- Fix os.sendfile() on illumos.
- Fixed writing binary Plist files larger than 4 GiB.
- The repr() of typing types containing Generic Alias Types
previously did not show the parameterized types in the
