Changelog for python39-base-3.9.20-222.1.i586.rpm :

* Wed Oct 02 2024 Matej Cepl - Drop .pyc files from docdir for reproducible builds (bsc#1230906).
* Fri Sep 20 2024 Matej Cepl - Add sphinx-802.patch to overcome working both with the most recent and older Sphinx versions.
* Mon Sep 09 2024 Matej Cepl - Update to 3.9.20: - Tests - gh-112769: The tests now correctly compare zlib version when :const:`zlib.ZLIB_RUNTIME_VERSION` contains non-integer suffixes. For example zlib-ng defines the version as ``1.3.0.zlib-ng``. - gh-117187: Fix XML tests for vanilla Expat <2.6.0. - Security - gh-123678: Upgrade libexpat to 2.6.3 - gh-121957: Fixed missing audit events around interactive use of Python, now also properly firing for ``python -i``, as well as for ``python -m asyncio``. The event in question is ``cpython.run_stdin``. - gh-122133: Authenticate the socket connection for the ``socket.socketpair()`` fallback on platforms where ``AF_UNIX`` is not available like Windows. Patch by Gregory P. Smith and Seth Larson . Reported by Ellie - gh-121285: Remove backtracking from tarfile header parsing for ``hdrcharset``, PAX, and GNU sparse headers (bsc#1230227, CVE-2024-6232). - gh-118486: :func:`os.mkdir` on Windows now accepts
*mode
* of ``0o700`` to restrict the new directory to the current user. This fixes CVE-2024-4030 affecting :func:`tempfile.mkdtemp` in scenarios where the base temporary directory is more permissive than the default. - gh-114572: :meth:`ssl.SSLContext.cert_store_stats` and :meth:`ssl.SSLContext.get_ca_certs` now correctly lock access to the certificate store, when the :class:`ssl.SSLContext` is shared across multiple threads (bsc#1226447, CVE-2024-0397). - gh-116741: Update bundled libexpat to 2.6.2 - Library - gh-123270: Applied a more surgical fix for malformed payloads in :class:`zipfile.Path` causing infinite loops (gh-122905) without breaking contents using legitimate characters (bsc#1229704, CVE-2024-8088). - gh-123067: Fix quadratic complexity in parsing ``\"``-quoted cookie values with backslashes by :mod:`http.cookies` (bsc#1229596, CVE-2024-7592). - gh-121650: :mod:`email` headers with embedded newlines are now quoted on output. The :mod:`~email.generator` will now refuse to serialize (write) headers that are unsafely folded or delimited; see :attr:`~email.policy.Policy.verify_generated_headers`. (Contributed by Bas Bloemsaat and Petr Viktorin in :gh:`121650`; CVE-2024-6923, bsc#1228780). - gh-113171: Fixed various false positives and false negatives in
* :attr:`ipaddress.IPv4Address.is_private` (see these docs for details)
* :attr:`ipaddress.IPv4Address.is_global`
* :attr:`ipaddress.IPv6Address.is_private`
* :attr:`ipaddress.IPv6Address.is_global` Also in the corresponding :class:`ipaddress.IPv4Network` and :class:`ipaddress.IPv6Network` attributes Fixes bsc#1226448 (CVE-2024-4032). - gh-102988: :func:`email.utils.getaddresses` and :func:`email.utils.parseaddr` now return ``(\'\', \'\')`` 2-tuples in more situations where invalid email addresses are encountered instead of potentially inaccurate values. Add optional
*strict
* parameter to these two functions: use ``strict=False`` to get the old behavior, accept malformed inputs. ``getattr(email.utils, \'supports_strict_parsing\', False)`` can be use to check if the
*strict
* paramater is available. Patch by Thomas Dwyer and Victor Stinner to improve the CVE-2023-27043 fix (bsc#1210638). - gh-67693: Fix :func:`urllib.parse.urlunparse` and :func:`urllib.parse.urlunsplit` for URIs with path starting with multiple slashes and no authority. Based on patch by Ashwin Ramaswami. - Core and Builtins - gh-112275: A deadlock involving ``pystate.c``\'s ``HEAD_LOCK`` in ``posixmodule.c`` at fork is now fixed.

It now raises BadZipFile when try to read an entry that overlaps with other entry or central directory (CVE-2024-0450, bsc#1221854). - 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 - gh-91133: Fix a bug in tempfile.TemporaryDirectory cleanup, which now no longer dereferences symlinks when working around file system permission errors (CVE-2023-6597, bsc#1219666). - Documentation - gh-115399: Document CVE-2023-52425 of Expat <2.6.0 under “XML vulnerabilities”. - Tools/Demos - gh-109991: Update GitHub CI workflows to use OpenSSL 3.0.11 and multissltests to use 1.1.1w and 3.0.11.- Remove upstreamed patches: - CVE-2023-6597-TempDir-cleaning-symlink.patch - libexpat260.patch- Refreshed patches: - F00251-change-user-install-location.patch - python-3.3.0b1-localpath.patch

* Tue Feb 20 2024 Matej Cepl - Remove double definition of /usr/bin/idle%%{version} in %%files.
* Thu Feb 15 2024 Daniel Garcia - Add upstream patch libexpat260.patch, Fix tests for XMLPullParser with Expat 2.6.0, gh#python/cpython#115289
* Mon Dec 18 2023 Matej Cepl - 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 Sep 06 2023 Daniel Garcia - Update to 3.9.18 (bsc#1214692): - (bsc#1215454, 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 symlinks into account when determining their target, so it will no longer reject some valid tarballs with LinkOutsideDestinationError. - gh-107565: Update multissltests and GitHub CI workflows to use OpenSSL 1.1.1v, 3.0.10, and 3.1.2.- Refresh all patches: - 98437-sphinx.locale._-as-gettext-in-pyspecific.patch - 99366-patch.dict-can-decorate-async.patch - Revert-gh105127-left-tests.patch - bpo-31046_ensurepip_honours_prefix.patch - decimal.patch - distutils-reproducible-compile.patch - gh-78214-marshal_stabilize_FLAG_REF.patch - python-3.3.0b1-localpath.patch - python-3.3.0b1-test-posix_fadvise.patch - python3-imp-returntype.patch - subprocess-raise-timeout.patch - support-expat-CVE-2022-25236-patched.patch - downport-Sphinx-features.patch
* Thu Aug 03 2023 Matej Cepl - 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).
* Sat Jul 29 2023 Matej Cepl - Add bpo-37596-make-set-marshalling.patch making marshalling of `set` and `frozenset` deterministic (bsc#1211765).

* Wed Jun 28 2023 Matej Cepl - Update to 3.9.17 (bsc#1212015): - 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). - gh-102126: Fixed a deadlock at shutdown when clearing thread states if any finalizer tries to acquire the runtime head lock. - gh-100892: Fixed a crash due to a race while iterating over thread states in clearing threading.local.- Remove upstreamed patches: - CVE-2023-24329-blank-URL-bypass.patch - CVE-2007-4559-filter-tarfile_extractall.patch
* Sat May 06 2023 Matej Cepl - Add 99366-patch.dict-can-decorate-async.patch fixing gh#python/cpython#98086 (backport from Python 3.10 patch in gh#python/cpython!99366), fixing bsc#1211158.
* Wed May 03 2023 Matej Cepl - Add CVE-2007-4559-filter-tarfile_extractall.patch to fix CVE-2007-4559 (bsc#1203750) by adding the filter for tarfile.extractall (PEP 706).
* Tue Apr 18 2023 Steve Kowalik - Use python3 modules to build the documentation.
* Wed Mar 01 2023 Matej Cepl - 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 - Add provides for readline and sqlite3 to the main Python package.
* Fri Jan 27 2023 Thorsten Kukuk - Disable NIS for new products, it\'s deprecated and gets removed
* Fri Jan 13 2023 Martin Liška - Suppress warnings for Sphinx 6.0+.
* Thu Dec 08 2022 Matej Cepl - Update to 3.9.16: - python -m http.server no longer allows terminal control characters sent within a garbage request to be printed to the stderr server log. This is done by changing the http.server BaseHTTPRequestHandler .log_message method to replace control characters with a \\xHH hex escape before printing. - 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-2015-20107). - 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. - 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).- Removed upstreamed patches: - 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 - 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 - 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 - 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 - Update to 3.9.15: - 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. - Update bundled libexpat to 2.4.9
* Sun Sep 11 2022 Matej Cepl - Update to 3.9.14: - (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. 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. - Also other bug fixes: - http.server: Fix an open redirection vulnerability in the HTTP server when an URI path starts with //. Vulnerability discovered, and initial fix proposed, by Hamza Avvan. - Fix contextvars HAMT implementation to handle iteration over deep trees. The bug was discovered and fixed by Eli Libman. See MagicStack/immutables#84 for more details. - Fix binding of unix socket to empty address on Linux to use an available address from the abstract namespace, instead of “0”. - Suppress writing an XML declaration in open files in ElementTree.write() with encoding=\'unicode\' and xml_declaration=None. - Fix the formatting for await x and not x in the operator precedence table when using the help() system. - Fix ensurepip environment isolation for subprocess running pip. - Fix problem with test_ssl test_get_ciphers on systems that require perfect forward secrecy (PFS) ciphers. - test_ssl is now checking for supported TLS version and protocols in more tests.- Removed upstreamed patches: - CVE-2021-28861-double-slash-path.patch- Realign patches: - bpo-31046_ensurepip_honours_prefix.patch - sphinx-update-removed-function.patch
* Thu Sep 01 2022 Steve Kowalik - Add patch CVE-2021-28861-double-slash-path.patch:
* http.server: Fix an open redirection vulnerability in the HTTP server when an URI path starts with //. (bsc#1202624, CVE-2021-28861)
* Thu Jul 21 2022 Matej Cepl - Switch from %primary_interpreter to prjconf-defined %primary_python (gh#openSUSE/python-rpm-macros#127).
* Thu Jun 09 2022 Matej Cepl - Add CVE-2015-20107-mailcap-unsafe-filenames.patch to avoid CVE-2015-20107 (bsc#1198511, gh#python/cpython#68966), the command injection in the mailcap module.- Fix building of documentation and the universal configuration of the %primary_interpreter.- (bsc#1196784, CVE-2022-25236) Rename patch: support-expat-245.patch to support-expat-CVE-2022-25236-patched.patch and update the patch to detect expat >= 2.4.4 instead of >= 2.4.5 as it was fully patched against CVE-2022-25236.
* Fri May 20 2022 Matej Cepl - Update to 3.9.13: - Core and Builtins - gh-92311: Fixed a bug where setting frame.f_lineno to jump 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-46775: Some Windows system error codes(>= 10000) are now mapped into the correct errno and may now raise a subclass of OSError. Patch by Dong-hee Na. - 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 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-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-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-91734: Fix OSS audio support on Solaris. - 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. - gh-91676: Fix unittest.IsolatedAsyncioTestCase to shutdown 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-34480: Fix a bug where _markupbase raised an UnboundLocalError when an invalid keyword was found in marked section.

* Wed Oct 13 2021 Dominique Leuenberger - BuildRequire rpm-build-python: The provider to inject python(abi) has been moved there. rpm-build pulls rpm-build-python automatically in when building anything against python3-base, but this implies that the initial build of python3-base does not trigger the automatic installation.
* Tue Aug 31 2021 Matej Cepl - Update to 3.9.7: - Security - Replaced usage of tempfile.mktemp() with TemporaryDirectory to avoid a potential race condition. - Add auditing events to the marshal module, and stop raising code.__init__ events for every unmarshalled code object. Directly instantiated code objects will continue to raise an event, and audit event handlers should inspect or collect the raw marshal data. This reduces a significant performance overhead when loading from .pyc files. - Made the internal putcmd function in smtplib sanitize input for presence of \\r and \
characters to avoid (unlikely) command injection. - Core and Builtins - Fixed pickling of range iterators that iterated for over 2
*

Patch by Pablo Galindo. - Fix undefined behaviour in complex object exponentiation. - Remove uses of PyObject_GC_Del() in error path when initializing types.GenericAlias. - Remove the pass-through for hash() of weakref.proxy objects to prevent unintended consequences when the original referred object dies while the proxy is part of a hashable object. Patch by Pablo Galindo. - Fix ltrace functionality when exceptions are raised. Patch by Pablo Galindo - Fix a crash at Python exit when a deallocator function removes the last strong reference to a heap type.

For a while the ipaddress module used to accept ambiguous leading zeros. - bpo-43075 (CVE-2021-3733, bsc#1189287): 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).

* Wed Apr 28 2021 Matej Cepl - 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().

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.

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).

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: - CVE-2021-3177-buf_ovrfl_PyCArg_repr.patch - bpo-31046_ensurepip_honours_prefix.patch - python-3.3.0b1-fix_date_time_compiler.patch - skip_random_failing_tests.patch - sphinx-update-removed-function.patch
