+++++++++++ Python News +++++++++++ What's New in Python 3.9.7 final? ================================= *Release date: 2021-08-30* Security -------- - bpo-42278: Replaced usage of :func:`tempfile.mktemp` with :class:`~tempfile.TemporaryDirectory` to avoid a potential race condition. - bpo-41180: Add auditing events to the :mod:`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. - bpo-44394: Update the vendored copy of libexpat to 2.4.1 (from 2.2.8) to get the fix for the CVE-2013-0340 "Billion Laughs" vulnerability. This copy is most used on Windows and macOS. - bpo-43124: Made the internal ``putcmd`` function in :mod:`smtplib` sanitize input for presence of ``\r`` and ``\n`` characters to avoid (unlikely) command injection. Core and Builtins ----------------- - bpo-45018: Fixed pickling of range iterators that iterated for over 2**32 times. - bpo-44962: 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 asyncio.run where shutdown_asyncgens is not run - bpo-44954: Fixed a corner case bug where the result of ``float.fromhex('0x.8p-1074')`` was rounded the wrong way. - bpo-44947: Refine the syntax error for trailing commas in import statements. Patch by Pablo Galindo. - bpo-44698: Restore behaviour of complex exponentiation with integer-valued exponent of type :class:`float` or :class:`complex`. - bpo-44885: Correct the ast locations of f-strings with format specs and repeated expressions. Patch by Pablo Galindo - bpo-44872: Use new trashcan macros (Py_TRASHCAN_BEGIN/END) in frameobject.c instead of the old ones (Py_TRASHCAN_SAFE_BEGIN/END). - bpo-33930: Fix segmentation fault with deep recursion when cleaning method objects. Patch by Augusto Goulart and Pablo Galindo. - bpo-25782: Fix bug where ``PyErr_SetObject`` hangs when the current exception has a cycle in its context chain. - bpo-44856: Fix reference leaks in the error paths of ``update_bases()`` and ``__build_class__``. Patch by Pablo Galindo. - bpo-44698: Fix undefined behaviour in complex object exponentiation. - bpo-44562: Remove uses of :c:func:`PyObject_GC_Del` in error path when initializing :class:`types.GenericAlias`. - bpo-44523: Remove the pass-through for :func:`hash` of :class:`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. - bpo-44472: Fix ltrace functionality when exceptions are raised. Patch by Pablo Galindo - bpo-44184: Fix a crash at Python exit when a deallocator function removes the last strong reference to a heap type. Patch by Victor Stinner. - bpo-39091: Fix crash when using passing a non-exception to a generator's ``throw()`` method. Patch by Noah Oxer Library ------- - bpo-41620: :meth:`~unittest.TestCase.run` now always return a :class:`~unittest.TestResult` instance. Previously it returned ``None`` if the test class or method was decorated with a skipping decorator. - bpo-43913: Fix bugs in cleaning up classes and modules in :mod:`unittest`: * Functions registered with :func:`~unittest.addModuleCleanup` were not called unless the user defines ``tearDownModule()`` in their test module. * Functions registered with :meth:`~unittest.TestCase.addClassCleanup` were not called if ``tearDownClass`` is set to ``None``. * Buffering in :class:`~unittest.TestResult` did not work with functions registered with ``addClassCleanup()`` and ``addModuleCleanup()``. * 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. - bpo-45001: Made email date parsing more robust against malformed input, namely a whitespace-only ``Date:`` header. Patch by Wouter Bolsterlee. - bpo-44449: Fix a crash in the signal handler of the :mod:`faulthandler` module: no longer modify the reference count of frame objects. Patch by Victor Stinner. - bpo-44955: Method :meth:`~unittest.TestResult.stopTestRun` is now always called in pair with method :meth:`~unittest.TestResult.startTestRun` for :class:`~unittest.TestResult` objects implicitly created in :meth:`~unittest.TestCase.run`. Previously it was not called for test methods and classes decorated with a skipping decorator. - bpo-38956: :class:`argparse.BooleanOptionalAction`'s default value is no longer printed twice when used with :class:`argparse.ArgumentDefaultsHelpFormatter`. - bpo-44581: Upgrade bundled pip to 21.2.3 and setuptools to 57.4.0 - bpo-44849: Fix the :func:`os.set_inheritable` function on FreeBSD 14 for file descriptor opened with the :data:`~os.O_PATH` flag: ignore the :data:`~errno.EBADF` error on ``ioctl()``, fallback on the ``fcntl()`` implementation. Patch by Victor Stinner. - bpo-44605: The @functools.total_ordering() decorator now works with metaclasses. - bpo-44822: :mod:`sqlite3` user-defined functions and aggregators returning :class:`strings <str>` with embedded NUL characters are no longer truncated. Patch by Erlend E. Aasland. - bpo-44815: Always show ``loop=`` arg deprecations in :func:`asyncio.gather` and :func:`asyncio.sleep` - bpo-44806: Non-protocol subclasses of :class:`typing.Protocol` ignore now the ``__init__`` method inherited from protocol base classes. - bpo-44667: The :func:`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 - bpo-42853: Fix ``http.client.HTTPSConnection`` fails to download >2GiB data. - bpo-44752: :mod:`rcompleter` does not call :func:`getattr` on :class:`property` objects to avoid the side-effect of evaluating the corresponding method. - bpo-44720: ``weakref.proxy`` objects referencing non-iterators now raise ``TypeError`` rather than dereferencing the null ``tp_iternext`` slot and crashing. - bpo-44704: The implementation of ``collections.abc.Set._hash()`` now matches that of ``frozenset.__hash__()``. - bpo-44666: Fixed issue in :func:`compileall.compile_file` when ``sys.stdout`` is redirected. Patch by Stefan Hölzl. - bpo-40897: Give priority to using the current class constructor in :func:`inspect.signature`. Patch by Weipeng Hong. - bpo-44608: Fix memory leak in :func:`_tkinter._flatten` if it is called with a sequence or set, but not list or tuple. - bpo-41928: Update :func:`shutil.copyfile` to raise :exc:`FileNotFoundError` instead of confusing :exc:`IsADirectoryError` when a path ending with a :const:`os.path.sep` does not exist; :func:`shutil.copy` and :func:`shutil.copy2` are also affected. - bpo-44566: handle StopIteration subclass raised from @contextlib.contextmanager generator - bpo-44558: Make the implementation consistency of :func:`~operator.indexOf` between C and Python versions. Patch by Dong-hee Na. - bpo-41249: Fixes ``TypedDict`` to work with ``typing.get_type_hints()`` and postponed evaluation of annotations across modules. - bpo-44461: Fix bug with :mod:`pdb`'s handling of import error due to a package which does not have a ``__main__`` module - bpo-42892: Fixed an exception thrown while parsin
