python39-3.9.19-1.2 RPM for aarch64

From OpenSuSE Ports Tumbleweed for aarch64

Name: python39 Distribution: openSUSE Tumbleweed
Version: 3.9.19 Vendor: openSUSE
Release: 1.2 Build date: Sun Mar 24 01:43:14 2024

Summary: Python 3 Interpreter
Python 3 is modern interpreted, object-oriented programming language,
often compared to Tcl, Perl, Scheme, or Java.  You can find an overview
of Python in the documentation and tutorials included in the python3-doc

This package supplies rich command line features provided by readline,
and sqlite3 support for the interpreter core, thus forming a so called
"extended" runtime.
Installing "python3" is sufficient for the vast majority of usecases.
In addition, recommended packages provide UI toolkit support (python3-curses,
python3-tk), legacy UNIX database bindings (python3-dbm), and the IDLE
development environment (python3-idle).

    - gh-104049: Do not expose the local on-disk
      location in directory indexes produced by

    - 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).

* 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
    - 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
* 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
* 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 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.

* 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.

      testcapi.RecursingInfinitelyError, and types.GenericAlias.
    - The functions affected are 24 methods in ctypes.
    - Patch by Oleg Iarygin.

      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
    - 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
    - gh-91734: Fix OSS audio support on Solaris.

      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. Patch by Marek Suscak.
    - 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.

      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:

      ‘a’ are treated equivalently to ‘w’ when argument is ‘-’.
      Patch contributed by Josh Rosenberg
  - Update to 3.9.11:
    - bpo-46852: Rename the private undocumented
      float.__set_format__() method to float.__setformat__() to fix

      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

      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

      for URI
    - 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-46672: Fix NameError in asyncio.gather() when initial
      type check fails.
    - 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

      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.

  - BuildRequire rpm-build-python: The provider to inject python(abi)
    has been moved there. rpm-build pulls rpm-build-python

  - 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 \n characters to avoid (unlikely)
      command injection.
    - Core and Builtins
    - Fixed pickling of range iterators that iterated for over
      2**32 times.
    - Fix a race in WeakKeyDictionary, WeakValueDictionary and
      WeakSet when two threads attempt to commit the last pending
      removal. This fixes asyncio.create_task and fixes a data
      loss in where shutdown_asyncgens is not run
    - Fixed a corner case bug where the result of
      float.fromhex('0x.8p-1074') was rounded the wrong way.

      and repeated expressions. Patch by Pablo Galindo
    - Use new trashcan macros (Py_TRASHCAN_BEGIN/END) in
      frameobject.c instead of the old ones
    - Fix segmentation fault with deep recursion when cleaning
      method objects. Patch by Augusto Goulart and Pablo Galindo.
    - Fix bug where PyErr_SetObject hangs when the current
      exception has a cycle in its context chain.
    - Fix reference leaks in the error paths of update_bases()
      and __build_class__. 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. Patch by

    - Fix crash when using passing a non-exception to
      a generator’s throw() method. Patch by Noah Oxer
    - Library
    - run() now always return a TestResult instance. Previously
      it returned None if the test class or method was decorated
      with a skipping decorator.
    - Fix bugs in cleaning up classes and modules in unittest:
    - Functions registered with addModuleCleanup() were not
      called unless the user defines tearDownModule() in
      their test module.
    - Functions registered with addClassCleanup() were not
      called if tearDownClass is set to None.
    - Buffering in TestResult did not work with functions
      registered with addClassCleanup() and
    - Errors in functions registered with addClassCleanup()
      and addModuleCleanup() were not handled correctly in
      buffered and debug modes.
    - Errors in setUpModule() and functions registered with
      addModuleCleanup() were reported in wrong order.
    - And several lesser bugs.
    - Made email date parsing more robust against malformed
      input, namely a whitespace-only Date: header. Patch by
      Wouter Bolsterlee.
    - Fix a crash in the signal handler of the faulthandler
      module: no longer modify the reference count of frame
      objects. Patch by Victor Stinner.
    - Method stopTestRun() is now always called in pair with
      method startTestRun() for TestResult objects implicitly
      created in run(). Previously it was not called for test
      methods and classes decorated with a skipping decorator.
    - argparse.BooleanOptionalAction’s default value is no longer
      printed twice when used with
    - Upgrade bundled pip to 21.2.3 and setuptools to 57.4.0
    - Fix the os.set_inheritable() function on FreeBSD 14 for
      file descriptor opened with the O_PATH flag: ignore the
      EBADF error on ioctl(), fallback on the fcntl()
      implementation. Patch by Victor Stinner.
    - The @functools.total_ordering() decorator now works with
    - sqlite3 user-defined functions and aggregators returning
      strings with embedded NUL characters are no longer
      truncated. Patch by Erlend E. Aasland.
    - Always show loop= arg deprecations in asyncio.gather() and
    - Non-protocol subclasses of typing.Protocol ignore now the
      __init__ method inherited from protocol base classes.
    - The tokenize.tokenize() doesn’t incorrectly generate
      a NEWLINE token if the source doesn’t end with a new line
      character but the last line is a comment, as the function
      is already generating a NL token. Patch by Pablo Galindo
    - Fix http.client.HTTPSConnection fails to download >2GiB
    - rcompleter does not call getattr() on property objects to
      avoid the side-effect of evaluating the corresponding
    - weakref.proxy objects referencing non-iterators now raise
      TypeError rather than dereferencing the null tp_iternext
      slot and crashing.
    - The implementation of now
      matches that of frozenset.__hash__().
    - Fixed issue in compileall.compile_file() when sys.stdout is
      redirected. Patch by Stefan Hölzl.
    - Give priority to using the current class constructor in
      inspect.signature(). Patch by Weipeng Hong.
    - Fix memory leak in _tkinter._flatten() if it is called with
      a sequence or set, but not list or tuple.
    - Update shutil.copyfile() to raise FileNotFoundError instead
      of confusing IsADirectoryError when a path ending with
      a os.path.sep does not exist; shutil.copy() and
      shutil.copy2() are also affected.
    - handle StopIteration subclass raised from
      @contextlib.contextmanager generator
    - Make the implementation consistency of indexOf() between
      C and Python versions. Patch by Dong-hee Na.
    - Fixes TypedDict to work with typing.get_type_hints() and
      postponed evaluation of annotations across modules.
    - Fix bug with pdb’s handling of import error due to
      a package which does not have a __main__ module
    - Fixed an exception thrown while parsing a malformed
      multipart email by email.message.EmailMessage.
    - pathlib.PureWindowsPath.is_reserved() now identifies
      a greater range of reserved filenames, including those with
      trailing spaces or colons.
    - Handle exceptions from parsing the arg of pdb’s run/restart
    - The sqlite3 context manager now performs a rollback (thus
      releasing the database lock) if commit failed. Patch by
      Luca Citi and Erlend E. Aasland.
    - Improved string handling for sqlite3 user-defined functions
      and aggregates:
    - It is now possible to pass strings with embedded null
      characters to UDFs
    - Conversion failures now correctly raise MemoryError
    - Patch by Erlend E. Aasland.
    - Handle RecursionError in TracebackException’s constructor,
      so that long exceptions chains are truncated instead of
      causing traceback formatting to fail.
    - Fix email.message.EmailMessage.set_content() when called
      with binary data and 7bit content transfer encoding.
    - The compresslevel and preset keyword arguments of are now both documented and tested.

      fail to compile files with a modification time after the
      year 2038.
    - Fix test___all__ on platforms lacking a shared memory
    - Pass multiprocessing BaseProxy argument manager_owned
      through AutoProxy.
    - email.utils.getaddresses() now accepts email.header.Header
      objects along with string values. Patch by Zackery Spytz.
    - lib2to3 now recognizes async generators everywhere.
    - Fix TypeError when required subparsers without dest do not
      receive arguments. Patch by Anthony Sottile.
    - Documentation
    - Removed the othergui.rst file, any references to it, and
      the list of GUI frameworks in the FAQ. In their place I’ve
      added links to the Python Wiki page on GUI frameworks.
    - Update the definition of __future__ in the glossary by
      replacing the confusing word “pseudo-module” with a more
      accurate description.
    - Add typical examples to os.path.splitext docs
    - Clarify that shutil.make_archive() is not thread-safe due
      to reliance on changing the current working directory.
    - Update of three expired hyperlinks in
      Doc/distributing/index.rst: “Project structure”, “Building
      and packaging the project”, and “Uploading the project to
      the Python Packaging Index”.
    - Updated the docstring and docs of filecmp.cmp() to be more
      accurate and less confusing especially in respect to
      shallow arg.
    - Match the docstring and python implementation of countOf()
      to the behavior of its c implementation.
    - List all kwargs for textwrap.wrap(), textwrap.fill(), and
      textwrap.shorten(). Now, there are nav links to attributes
      of TextWrap, which makes navigation much easier while
      minimizing duplication in the documentation.
    - Clarify that atexit uses equality comparisons internally.
    - Documentation of csv.Dialect is more descriptive.
    - Fix documentation for the return type of
    - Add a “Security Considerations” index which links to
      standard library modules that have explicitly documented
      security considerations.
    - Remove the unqualified claim that tkinter is threadsafe. It
      has not been true for several years and likely never was.
      An explanation of what is true may be added later, after
      more discussion, and possibly after patching _tkinter.c,
    - Tests
    - Add calls of gc.collect() in tests to support PyPy.
    - Made tests relying on the _asyncio C extension module
      optional to allow running on alternative Python
      implementations. Patch by Serhiy Storchaka.
    - Fix auto history tests of test_readline: sometimes, the
      newline character is not written at the end, so don’t
      expect it in the output.
    - Add ability to wholesale silence DeprecationWarnings while
      running the regression test suite.
    - Notify users running test_decimal regression tests on macOS
      of potential harmless “malloc can’t allocate region”
      messages spewed by test_decimal.
    - Fixed floating point precision issue in turtle tests.

      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

      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

      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
    - 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.

      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
    - 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.

      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

    properly replace it during upgrades.  (bsc#1181324)
* Mon Feb 08 2021 Matej Cepl <>
  - 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
    - 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
    - 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
    - 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.
    - 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
    - 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
    - Fixed The function accepts now the
      representation of the default state as empty sequence (as
      returned by The structure of the result is now
      the same on all platform and does not depend on the value of
    - 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 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
    - 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
    - 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
    - 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
    - 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
    - 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
    - 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
    - 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

      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.

    - 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.
