- Thus we can remove Revert-gh105127-left-tests.patch, which is
now useless.
* Mon Sep 04 2023 Daniel Garcia <daniel.garcia@suse.com>
- Add fix-sphinx-72.patch to make it work with latest sphinx version
gh#python/cpython#97950
- Update to 3.10.13 (bsc#1214692):
- 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.
- gh-107845: tarfile.data_filter() now takes the location of

- Update to 3.10.12:
- 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-2023-24329-blank-URL-bypass.patch

argument to argparse.ArgumentParser.add_argument() were
dropped. Patch by Yeojin Kim.
- gh-102179: Fix os.dup2() error message for negative fds.
- gh-101961: For the binary mode, fileinput.hookcompressed()
doesn’t set the encoding value even if the value is
None. Patch by Gihwan Kim.

local variables.
- gh-96931: Fix incorrect results from
ssl.SSLSocket.shared_ciphers()
- gh-88233: Correctly preserve “extra” fields in zipfile

- gh-95495: When built against OpenSSL 3.0, the ssl module
had a bug where it reported unauthenticated EOFs (i.e.
without close_notify) as a clean TLS-level EOF. It now
raises SSLEOFError, matching the behavior in previous
versions of OpenSSL. The options attribute on SSLContext
also no longer includes OP_IGNORE_UNEXPECTED_EOF by
default. This option may be set to specify the previous
OpenSSL 3.0 behavior.
- gh-94440: Fix a concurrent.futures.process bug where
ProcessPoolExecutor shutdown could hang after a future has
been quickly submitted and canceled.

- Removed upstreamed:
- invalid-json.patch
* Mon Mar 13 2023 Matej Cepl <mcepl@suse.com>
- Add invalid-json.patch fixing invalid JSON in
Doc/howto/logging-cookbook.rst (somehow similar to
gh#python/cpython#102582).
* Wed Mar 01 2023 Matej Cepl <mcepl@suse.com>
- Update to 3.10.10:
Bug fixes and regressions handling, no change of behaviour and
no security bugs fixed.
- Add CVE-2023-24329-blank-URL-bypass.patch (CVE-2023-24329,
bsc#1208471) blocklists bypass via the urllib.parse component
when supplying a URL that starts with blank characters
* Tue Feb 21 2023 Matej Cepl <mcepl@suse.com>
- Add provides for readline and sqlite3 to the main Python
package.
* Fri Jan 27 2023 Thorsten Kukuk <kukuk@suse.com>
- Disable NIS for new products, it's deprecated and gets removed
* Thu Dec 08 2022 Matej Cepl <mcepl@suse.com>
- Update to 3.10.9:
- 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.
- Update bundled libexpat to 2.5.0
- Port XKCP’s fix for the buffer overflows in SHA-3
(CVE-2022-37454).
- 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 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
- Update faulthandler to emit an error message with
the proper unexpected signal number. Patch by Dong-hee Na.
- Fix subscription of types.GenericAlias instances
containing bare generic types: for example tuple[A, T][int],
where A is a generic type, and T is a type variable.
- 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.
- 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.
- Fixed bug where inspect.signature() reported
incorrect arguments for decorated methods.
- Fix SystemError in ctypes when exception was not
set during __initsubclass__.
- Fix statistics.NormalDist pickle with 0 and 1
protocols.
- Update the bundled copy of pip to version 22.3.1.
- Apply bugfixes from importlib_metadata 4.11.4,
namely: In PathDistribution._name_from_stem, avoid
including parts of the extension in the result. In
PathDistribution._normalized_name, ensure names loaded from
the stem of the filename are also normalized, ensuring
duplicate entry points by packages varying only by
non-normalized name are hidden.
- 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.
- Fix argument typechecks in _overlapped.WSAConnect()
and _overlapped.Overlapped.WSASendTo() functions.
- 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.
- Update the bundled copies of pip and setuptools to
versions 22.3 and 65.5.0 respectively.
- 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.
- Make sure patch.dict() can be applied on async
functions.
- 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.
- Prevent error when activating venv in nested fish
instances.
- 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).
- Skip test_normalization() of test_unicodedata
if it fails to download NormalizationTest.txt file from
pythontest.net. Patch by Victor Stinner.
- 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 -Wimplicit-int compiler warning in configure
check for PTHREAD_SCOPE_SYSTEM.
- Specify the full path to the source location for
make docclean (needed for cross-builds).
- Fix NO_MISALIGNED_ACCESSES being not defined
for the SHA3 extension when HAVE_ALIGNED_REQUIRED is
set. Allowing builds on hardware that unaligned memory
accesses are not allowed.
- Fix handling of module docstrings in
Tools/i18n/pygettext.py.
- Remove upstreamed patches:
- 98437-sphinx.locale._-as-gettext-in-pyspecific.patch
- CVE-2015-20107-mailcap-unsafe-filenames.patch
- CVE-2022-42919-loc-priv-mulitproc-forksrv.patch
- CVE-2022-45061-DoS-by-IDNA-decode.patch
* Wed Nov 09 2022 Matej Cepl <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.
* Thu Nov 03 2022 Matej Cepl <mcepl@suse.com>
- Add CVE-2022-42919-loc-priv-mulitproc-forksrv.patch to avoid
CVE-2022-42919 (bsc#1204886) avoiding Linux specific local
privilege escalation via the multiprocessing forkserver start
method.
* Fri Oct 21 2022 Matej Cepl <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).
* Wed Oct 19 2022 Matej Cepl <mcepl@suse.com>
- Update to 3.10.8:
- Fix multiplying a list by an integer (list *= int): detect
the integer overflow when the new allocated length is close
to the maximum size.
- 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. (originally
filed as CVE-2022-37460, later withdrawn)
- 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.
- 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.
- The deprecated mailcap module now refuses to inject unsafe
text (filenames, MIME types, parameters) into shell
commands. Instead of using such text, it will warn and act
as if a match was not found (or for test commands, as if the
test failed).
- os.sched_yield() now release the GIL while calling
sched_yield(2).
- Bugfix: PyFunction_GetAnnotations() should return a borrowed
reference. It was returning a new reference.
- Fixed a missing incref/decref pair in
Exception.__setstate__().
- Fix overly-broad source position information for chained
comparisons used as branching conditions.
- Fix undefined behaviour in _testcapimodule.c.
- 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.
- 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.
- Do not expose KeyWrapper in _functools.
- When loading a file with invalid UTF-8 inside a multi-line
string, a correct SyntaxError is emitted.
- Disable incorrect pickling of the C implemented classmethod
descriptors.
- Fix AttributeError missing name and obj attributes in .
object.__getattribute__() bpo-42316: Document some places .
where an assignment expression needs parentheses .
- 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.
- Fixes AttributeError when subprocess.check_output() is used
with argument input=None and either of the arguments encoding
or errors are used.
- 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.
- Make Semaphore run faster.
- 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.
- 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 the faulthandler implementation of
faulthandler.register(signal, chain=True) if the sigaction()
function is not available: don’t call the previous signal
handler if it’s NULL.
- In inspect, fix overeager replacement of “typing.” in
formatting annotations.
- Fix asyncio.streams.StreamReaderProtocol to keep a strong
reference to the created task, so that it’s not garbage
collected
- 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.
- Fixed flickering of the turtle window when the tracer is
turned off.
- Allow asyncio.StreamWriter.drain() to be awaited concurrently
by multiple tasks.
- Fix broken asyncio.Semaphore when acquire is cancelled.
- Fix ast.unparse() when ImportFrom.level is None
- Improve performance of urllib.request.getproxies_environment
when there are many environment variables
- Fix ! in c domain ref target syntax via a conf.py patch, so
it works as intended to disable ref target resolution.
- 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.
- Update tutorial introduction output to use 3.10+ SyntaxError
invalid range.
- Remove upstreamed test-int-timing.patch.
* Sun Sep 18 2022 Andreas Schwab <schwab@suse.de>
- test-int-timing.patch: gh-96710: Make the test timing more lenient for
the int/str DoS regression test. (#96717)
* Sun Sep 11 2022 Matej Cepl <mcepl@suse.com>
- Update to 3.10.7:
- Fix for CVE-2020-10735 (bsc#1203125) 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.
- Other bug fixes:
- Fixed a bug that caused _PyCode_GetExtra to return garbage
for negative indexes.
- Fix format string in _PyPegen_raise_error_known_location

positional-only params when passed feature_version less
than (3, 8).

the rollover time has passed.
- Fix unused localName parameter in the Attr class in
xml.dom.minidom.

over a list comprehension could misbehave or crash.
- gh-92112: Fix crash triggered by an evil custom mro() on
a metaclass.
- gh-92036: Fix a crash in subinterpreters related to the
garbage collector. When a subinterpreter is deleted,
untrack all objects tracked by its GC. To prevent a crash
in deallocator functions expecting objects to be tracked by
the GC, leak a strong reference to these objects on
purpose, so they are never deleted and their deallocator
functions are not called. Patch by Victor Stinner.
- gh-91421: Fix a potential integer overflow in
_Py_DecodeUTF8Ex.
- bpo-47212: Raise IndentationError instead of SyntaxError
for a bare except with no following indent. Improve
SyntaxError locations for an un-parenthesized generator
used as arguments. Patch by Matthieu Dartiailh.
- bpo-47182: Fix a crash when using a named unicode character
like "\N{digit nine}" after the main interpreter has been
initialized a second time.

interactive mode if the tokenizer buffers are
uninitialized. Patch by Pablo Galindo.
- bpo-39829: Removed the __len__() call when initializing
a list and moved initializing to list_extend. Patch by
Jeremiah Pascual.
- bpo-46962: Classes and functions that unconditionally
declared their docstrings ignoring the
- -without-doc-strings compilation flag no longer do so.
- The classes affected are ctypes.UnionType,
pickle.PickleBuffer, testcapi.RecursingInfinitelyError, and
types.GenericAlias.
- The functions affected are 24 methods in ctypes.
- Patch by Oleg Iarygin.
- bpo-36819: Fix crashes in built-in encoders with error
handlers that return position less or equal than the
starting position of non-encodable characters.
- Library
- gh-93156: Accessing the pathlib.PurePath.parents sequence
of an absolute path using negative index values produced
incorrect results.
- gh-89973: Fix re.error raised in fnmatch if the pattern
contains a character range with upper bound lower than
lower bound (e.g. [c-a]). Now such ranges are interpreted
as empty ranges.
- gh-93010: In a very special case, the email package tried
to append the nonexistent InvalidHeaderError to the defect
list. It should have been InvalidHeaderDefect.
- gh-92839: Fixed crash resulting from calling
bisect.insort() or bisect.insort_left() with the key
argument not equal to None.
- gh-91581: utcfromtimestamp() no longer attempts to resolve
fold in the pure Python implementation, since the fold is
never 1 in UTC. In addition to being slightly faster in the
common case, this also prevents some errors when the
timestamp is close to datetime.min. Patch by Paul Ganssle.
- gh-92530: Fix an issue that occurred after interrupting
threading.Condition.notify().
- gh-92049: Forbid pickling constants re._constants.SUCCESS
etc. Previously, pickling did not fail, but the result
could not be unpickled.
- bpo-47029: Always close the read end of the pipe used by
multiprocessing.Queue after the last write of buffered data
to the write end of the pipe to avoid BrokenPipeError at
garbage collection and at multiprocessing.Queue.close()
calls. Patch by Géry Ogam.
- gh-91401: Provide a fail-safe way to disable subprocess use
of vfork() via a private subprocess._USE_VFORK attribute.
While there is currently no known need for this, if you
find a need please only set it to False. File a CPython
issue as to why you needed it and link to that from
a comment in your code. This attribute is documented as
a footnote in 3.11.
- gh-91910: Add missing f prefix to f-strings in error
messages from the multiprocessing and asyncio modules.
- gh-91810: ElementTree method write() and function
tostring() now use the text file’s encoding (“UTF-8” if not
available) instead of locale encoding in XML declaration
when encoding="unicode" is specified.
- gh-91832: Add required attribute to argparse.Action repr
output.
- gh-91700: Compilation of regular expression containing
a conditional expression (?(group)...) now raises an
appropriate re.error if the group number refers to not
defined group. Previously an internal RuntimeError was
raised.

the per test event loop executor before returning from its
run method so that a not yet stopped or garbage collected
executor state does not persist beyond the test.
- gh-90568: Parsing \N escapes of Unicode Named Character
Sequences in a regular expression raises now re.error
instead of TypeError.
- gh-91595: Fix the comparison of character and integer
inside Tools.gdb.libpython.write_repr(). Patch by Yu Liu.
- gh-90622: Worker processes for
concurrent.futures.ProcessPoolExecutor are no longer
spawned on demand (a feature added in 3.9) when the
multiprocessing context start method is "fork" as that can
lead to deadlocks in the child processes due to a fork
happening while threads are running.
- gh-91575: Update case-insensitive matching in the re module
to the latest Unicode version.
- gh-91581: Remove an unhandled error case in the
C implementation of calls to datetime.fromtimestamp with no
time zone (i.e. getting a local time from an epoch
timestamp). This should have no user-facing effect other
than giving a possibly more accurate error message when
called with timestamps that fall on 10000-01-01 in the
local time. Patch by Paul Ganssle.
- bpo-47260: Fix os.closerange() potentially being a no-op in
a Linux seccomp sandbox.
- bpo-39064: zipfile.ZipFile now raises zipfile.BadZipFile
instead of ValueError when reading a corrupt zip file in
which the central directory offset is negative.
- bpo-47151: When subprocess tries to use vfork, it now falls
back to fork if vfork returns an error. This allows use in
situations where vfork isn’t allowed by the OS kernel.
- bpo-27929: Fix asyncio.loop.sock_connect() to only resolve
names for socket.AF_INET or socket.AF_INET6 families.
Resolution may not make sense for other families, like
socket.AF_BLUETOOTH and socket.AF_UNIX.
- bpo-43323: Fix errors in the email module if the charset
itself contains undecodable/unencodable characters.
- bpo-47101: hashlib.algorithms_available now lists only
algorithms that are provided by activated crypto providers

exception memory leak
- bpo-45393: Fix the formatting for await x and not x in the
operator precedence table when using the help() system.

does not have __doc__.
- bpo-45138: Fix a regression in the sqlite3 trace callback
where bound parameters were not expanded in the passed
statement string. The regression was introduced in Python
3.10 by bpo-40318. Patch by Erlend E. Aasland.
- bpo-44493: Add missing terminated NUL in sockaddr_un’s
length
- This was potentially observable when using non-abstract
AF_UNIX datagram sockets to processes written in another
programming language.
- bpo-42627: Fix incorrect parsing of Windows registry proxy
settings
- bpo-36073: Raise ProgrammingError instead of segfaulting on
recursive usage of cursors in sqlite3 converters. Patch by

to this was to always feed the function data in increments
smaller than 4GiB or to just call the zlib module function.
- bpo-39394: A warning about inline flags not at the start of
the regular expression now contains the position of the flag.
- bpo-47061: Deprecate the various modules listed by PEP 594:

- bpo-46615: When iterating over sets internally in
setobject.c, acquire strong references to the resulting items
from the set. This prevents crashes in corner-cases of
various set operations where the set gets mutated.
- bpo-45773: Remove two invalid “peephole” optimizations from
the bytecode compiler.
- bpo-43721: Fix docstrings of getter, setter, and deleter to
clarify that they create a new copy of the property.
- bpo-46503: Fix an assert when parsing some invalid N escape
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.
- bpo-46383: Fix invalid signature of _zoneinfo’s module_free
function to resolve a crash on wasm32-emscripten platform.
- bpo-46070: Py_EndInterpreter() now explicitly untracks all
objects currently tracked by the GC. Previously, if an object
was used later by another interpreter, calling
PyObject_GC_UnTrack() on the object crashed if the previous
or the next object of the PyGC_Head structure became
a dangling pointer. Patch by Victor Stinner.
- bpo-46339: Fix a crash in the parser when retrieving the
error text for multi-line f-strings expressions that do not
start in the first line of the string. Patch by Pablo Galindo
- bpo-46240: Correct the error message for unclosed parentheses
when the tokenizer doesn’t reach the end of the source when
the error is reported. Patch by Pablo Galindo
- bpo-46091: Correctly calculate indentation levels for lines
with whitespace character that are ended by line continuation
characters. Patch by Pablo Galindo

including bugfix for EntryPoint.extras, which was returning
match objects and not the extras strings.
- bpo-46985: Upgrade pip wheel bundled with ensurepip (pip
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.

urllib.request.HTTPPasswordMgr.find_user_password() and
urllib.request.HTTPPasswordMgrWithPriorAuth.is_authenticated()
which allowed to bypass authorization. For example, access to
URI example.org/foobar was allowed if the user was authorized
for URI example.org/foo.
- bpo-46643: In typing.get_type_hints(), support evaluating
stringified ParamSpecArgs and ParamSpecKwargs annotations.
Patch by Gregory Beauregard.
- bpo-45863: When the tarfile module creates a pax format
archive, it will put an integer representation of timestamps
in the ustar header (if possible) for the benefit of older
unarchivers, in addition to the existing full-precision
timestamps in the pax extended header.
- bpo-46676: Make typing.ParamSpec args and kwargs equal to
themselves. Patch by Gregory Beauregard.
- bpo-46672: Fix NameError in asyncio.gather() when initial
type check fails.

bare stringified TypeAlias annotations. Patch by Gregory
Beauregard.
- bpo-45948: Fixed a discrepancy in the C implementation of the
xml.etree.ElementTree module. Now, instantiating an
xml.etree.ElementTree.XMLParser with a target=None keyword
provides a default xml.etree.ElementTree.TreeBuilder target
as the Python implementation does.
- bpo-46521: Fix a bug in the codeop module that was
incorrectly identifying invalid code involving string quotes
as valid code.
- bpo-46581: Brings ParamSpec propagation for GenericAlias in
line with Concatenate (and others).

clickable.
- bpo-46400: expat: Update libexpat from 2.4.1 to 2.4.4
- bpo-46487: Add the get_write_buffer_limits method to
asyncio.transports.WriteTransport and to the SSL transport.
- bpo-45173: Note the configparser deprecations will be removed
in Python 3.12.
- bpo-46539: In typing.get_type_hints(), support evaluating
stringified ClassVar and Final annotations inside Annotated.
Patch by Gregory Beauregard.
- bpo-46491: Allow typing.Annotated to wrap typing.Final and
typing.ClassVar. Patch by Gregory Beauregard.
- bpo-46436: Fix command-line option -d/--directory in module
http.server which is ignored when combined with command-line
option --cgi. Patch by Géry Ogam.
- bpo-41403: Make mock.patch() raise a TypeError with
a relevant error message on invalid arg. Previously it
allowed a cryptic AttributeError to escape.
- bpo-46474: In importlib.metadata.EntryPoint.pattern, avoid
potential REDoS by limiting ambiguity in consecutive
whitespace.
- bpo-46469: asyncio generic classes now return
types.GenericAlias in __class_getitem__ instead of the same
class.
- bpo-46434: pdb now gracefully handles help when __doc__ is
missing, for example when run with pregenerated optimized
.pyc files.
- bpo-46333: The __eq__() and __hash__() methods of
typing.ForwardRef now honor the module parameter of
typing.ForwardRef. Forward references from different modules
are now differentiated.
- bpo-46246: Add missing __slots__ to
importlib.metadata.DeprecatedList. Patch by Arie Bovenberg.
- bpo-46266: Improve day constants in calendar.
- Now all constants (MONDAY … SUNDAY) are documented, tested,
and added to __all__.
- bpo-46232: The ssl module now handles certificates with bit
strings in DN correctly.
- bpo-43118: Fix a bug in inspect.signature() that was causing
it to fail on some subclasses of classes with
a __text_signature__ referencing module globals. Patch by
Weipeng Hong.

a argparse.BooleanOptionalAction argument’s default is
argparse.SUPPRESS and it has help specified. Patch by Felix
Fontein.
- bpo-44439: Fix .write() method of a member file in ZipFile,
when the input data is an object that supports the buffer
protocol, the file length may be wrong.
- bpo-45703: When a namespace package is imported before
another module from the same namespace is created/installed
in a different sys.path location while the program is
running, calling the importlib.invalidate_caches() function
will now also guarantee the new module is noticed.
- bpo-24959: Fix bug where unittest sometimes drops frames from
tracebacks of exceptions raised in tests.
- bpo-44791: Fix substitution of ParamSpec in Concatenate with
different parameter expressions. Substitution with a list of
types returns now a tuple of types. Substitution with
Concatenate returns now a Concatenate with concatenated lists
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 ‘-’.
Patch contributed by Josh Rosenberg
- bpo-46463: Fixes escape4chm.py script used when building the
CHM documentation file
- bpo-46913: Fix test_faulthandler.test_sigfpe() if Python is

optimization when testing compilation of its own C extensions
to significantly speed up the testing on non-debug builds of
CPython.
- bpo-46542: Fix test_json tests checking for RecursionError:
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__.
- bpo-45296: Clarify close, quit, and exit in IDLE. In the File
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.

- 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 Ben Greiner <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 Matej Cepl <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.

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.

- bsc1167501-invalid-alignment.patch
- skip_random_failing_tests.patch
- CVE-2019-5010-null-defer-x509-cert-DOS.patch
* Tue Feb 09 2021 Steve Kowalik <steven.kowalik@suse.com>
- Add Obsoletes for python3-base when primary interpreter is set to
properly replace it during upgrades. (bsc#1181324)
* Mon Feb 08 2021 Matej Cepl <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
GenericAlias. They have now been changed to do so.
- webbrowser: Ignore NotADirectoryError when calling
xdg-settings.
- binhex.binhex() consisently writes macOS 9 line endings.
- Fix a stack overflow error for asyncio Task or Future repr().
- The overflow occurs under some circumstances when a Task or
Future recursively returns itself.
- Fix memory leak in subprocess.Popen() in case an uid (gid)
specified in user (group, extra_groups) overflows uid_t
(gid_t).
- Improve asyncio.wait function to create the futures set just
one time.
- InvalidFileException and RecursionError are now the only
errors caused by loading malformed binary Plist file
(previously ValueError and TypeError could be raised in some
specific cases).
- Pickling heap types implemented in C with protocols 0 and
1 raises now an error instead of producing incorrect data.
- plistlib: fix parsing XML plists with hexadecimal integer
values
- Fix an incorrectly formatted error from
_codecs.charmap_decode() when called with a mapped value
outside the range of valid Unicode code points. PR by Max
Bernstein.
- Fix pickling pure Python datetime.time subclasses. Patch by
Dean Inwood.
- Fixed a bug that was causing ctypes.util.find_library() to
return None when triying to locate a library in an
environment when gcc>=9 is available and ldconfig is not.
Patch by Pablo Galindo
- C14N 2.0 serialisation in xml.etree.ElementTree failed for
unprefixed attributes when a default namespace was defined.
- Fix a bug in the symtable module that was causing
module-scope global variables to not be reported as both
local and global. Patch by Pablo Galindo.
- str() for the type attribute of the tkinter.Event object
always returns now the numeric code returned by Tk instead of
the name of the event type.
- fix tkinter.EventType Enum so all members are strings, and
none are tuples
- Fix SQLite3 segfault when backing up closed database. Patch
contributed by Peter David McCormick.
- Fix the tarfile module to write only basename of TAR file to
GZIP compression header.
- Allow ctypes.wintypes to be imported on non-Windows systems.
- shutil.which() now ignores empty entries in PATHEXT instead
of treating them as a match.
- Fix time-of-check/time-of-action issue in
subprocess.Popen.send_signal.
- Fix --outfile for cProfile / profile not writing the output
file in the original directory when the program being
profiled changes the working directory. PR by Anthony
Sottile.
- ZipFile truncates files to avoid corruption when a shorter
comment is provided in append (“a”) mode. Patch by Jan Mazur.
- Fixed KeyError exception when flattening an email to a string
attempts to replace a non-existent Content-Transfer-Encoding
header.
Documentation
- Fix the URL for the IMAP protocol documents.
- Document __format__ functionality for IP addresses.
- Clarify that subscription expressions are also valid for
certain classes and types in the standard library, and for
user-defined classes and types if the classmethod
__class_getitem__() is provided.
- Documented generic alias type and types.GenericAlias. Also
added an entry in glossary for generic types.
- In Programming FAQ “Sequences (Tuples/Lists)” section, add
“How do you remove multiple items from a list”.
- Fix RemovedInSphinx40Warning when building the documentation.
Patch by Dong-hee Na.
- Update the refcounts info of PyType_FromModuleAndSpec.
- Fix tarfile’s extractfile documentation
- Document some restrictions on the default string
representations of numeric classes.
Tests
- Reenable test_gdb on gdb 9.2 and newer:
https://bugzilla.redhat.com/show_bug.cgi?id=1866884 bug is
fixed in gdb 10.1.
- Fix test_asyncio.test_call_later() race condition: don’t
measure asyncio performance in the call_later() unit test.
The test failed randomly on the CI.
- Include _testinternalcapi module in Windows installer for
test suite
- Fix test_logging.test_race_between_set_target_and_flush():
the test now waits until all threads complete to avoid
leaking running threads.
- Avoid a test failure in test_lib2to3 if the module has
already imported at the time the test executes. Patch by
Pablo Galindo.
- Tests for CJK codecs no longer call eval() on content
received via HTTP.
- Fix test_site.test_license_exists_at_url(): call
urllib.request.urlcleanup() to reset the global
urllib.request._opener. Patch by Victor Stinner.
- test_ssl: skip test_min_max_version_mismatch when TLS 1.0 is
not available
- Add tests for SIGINT handling in the runpy module.
- Fixed a failure in test_tk.test_widgets.ScaleTest happening
when executing the test with Tk 8.6.10.
Build
- Fix a race condition in “make regen-all” when make -jN option
is used to run jobs in parallel. The clinic.py script now
only use atomic write to write files. Moveover, generated
files are now left unchanged if the content does not change,
to not change the file modification time.
- Update Py_UNREACHABLE to use __builtin_unreachable() if only
the compiler is able to use it. Patch by Dong-hee Na.
- Addressed three compiler warnings found by undefined behavior
sanitizer (ubsan).
IDLE
- Fix reporting offset of the RE error in searchengine.
- Get docstrings for IDLE calltips more often by using
inspect.getdoc.
- Mostly finish using ttk widgets, mainly for editor, settings,
and searches. Some patches by Mark Roseman.
- Use ‘IDLE Shell’ as shell title
- Rewrite the Calltips doc section.
- In calltips, stop reminding that ‘/’ marks the end of
positional-only arguments.
- Typing opening and closing parentheses inside the parentheses
of a function call will no longer cause unnecessary
“flashing” off and on of an existing open call-tip, e.g. when
typed in a string literal.
C API
- Fix potential crash in deallocating method objects when
dynamically allocated PyMethodDef’s lifetime is managed
through the self argument of a PyCFunction.
- Py_FileSystemDefaultEncodeErrors and Py_UTF8Mode are
available again in limited API.
- Readjustet and reapplied patches:
