Python 3.9.8

Core and Builtins
bpo-30570: Fixed a crash in issubclass() from infinite recursion when searching \ 
pathological __bases__ tuples.
bpo-45494: Fix parser crash when reporting errors involving invalid continuation \ 
characters. Patch by Pablo Galindo.
bpo-45385: Fix reference leak from descr_check. Patch by Dong-hee Na.
bpo-45167: Fix deepcopying of types.GenericAlias objects.
bpo-44219: Release the GIL while performing isatty system calls on arbitrary \ 
file descriptors. In particular, this affects os.isatty(), os.device_encoding() \ 
and io.TextIOWrapper. By extension, io.open() in text mode is also affected. \ 
This change solves a deadlock in os.isatty(). Patch by Vincent Michel in \ 
bpo-44219.
bpo-44959: Added fallback to extension modules with ‘.sl’ suffix on HP-UX
bpo-44050: Extensions that indicate they use global state (by setting m_size to \ 
-1) can again be used in multiple interpreters. This reverts to behavior of \ 
Python 3.8.
bpo-45121: Fix issue where Protocol.__init__ raises RecursionError when it’s \ 
called directly or via super(). Patch provided by Yurii Karabas.
bpo-45083: When the interpreter renders an exception, its name now has a \ 
complete qualname. Previously only the class name was concatenated to the module \ 
name, which sometimes resulted in an incorrect full name being displayed.

(This issue impacted only the C code exception rendering, the traceback module \ 
was using qualname already).
Library
bpo-45678: Fix bug in Python 3.9 that meant functools.singledispatchmethod \ 
failed to properly wrap the attributes of the target method. Patch by Alex \ 
Waygood.
bpo-45679: Fix caching of multi-value typing.Literal. Literal[True, 2] is no \ 
longer equal to Literal[1, 2].
bpo-45438: Fix typing.Signature string representation for generic builtin types.
bpo-45581: sqlite3.connect() now correctly raises MemoryError if the underlying \ 
SQLite API signals memory error. Patch by Erlend E. Aasland.
bpo-39679: Fix bug in functools.singledispatchmethod that caused it to fail when \ 
attempting to register a classmethod() or staticmethod() using type annotations. \ 
Patch contributed by Alex Waygood.
bpo-45515: Add references to zoneinfo in the datetime documentation, mostly \ 
replacing outdated references to dateutil.tz. Change by Paul Ganssle.
bpo-45467: Fix incremental decoder and stream reader in the \ 
“raw-unicode-escape” codec. Previously they failed if the escape sequence \ 
was split.
bpo-45461: Fix incremental decoder and stream reader in the “unicode-escape” \ 
codec. Previously they failed if the escape sequence was split.
bpo-45239: Fixed email.utils.parsedate_tz() crashing with UnboundLocalError on \ 
certain invalid input instead of returning None. Patch by Ben Hoyt.
bpo-44904: Fix bug in the doctest module that caused it to fail if a docstring \ 
included an example with a classmethod property. Patch by Alex Waygood.
bpo-45406: Make inspect.getmodule() catch FileNotFoundError raised by \ 
:’func:inspect.getabsfile, and return None to indicate that the module could \ 
not be determined.
bpo-45262: Prevent use-after-free in asyncio. Make sure the cached running loop \ 
holder gets cleared on dealloc to prevent use-after-free in get_running_loop
bpo-45386: Make xmlrpc.client more robust to C runtimes where the underlying C \ 
strftime function results in a ValueError when testing for year formatting \ 
options.
bpo-45371: Fix clang rpath issue in distutils. The UnixCCompiler now uses \ 
correct clang option to add a runtime library directory (rpath) to a shared \ 
library.
bpo-20028: Improve error message of csv.Dialect when initializing. Patch by \ 
Vajrasky Kok and Dong-hee Na.
bpo-45343: Update bundled pip to 21.2.4 and setuptools to 58.1.0
bpo-41710: On Unix, if the sem_clockwait() function is available in the C \ 
library (glibc 2.30 and newer), the threading.Lock.acquire() method now uses the \ 
monotonic clock (time.CLOCK_MONOTONIC) for the timeout, rather than using the \ 
system clock (time.CLOCK_REALTIME), to not be affected by system clock changes. \ 
Patch by Victor Stinner.
bpo-45328: Fixed http.client.HTTPConnection to work properly in OSs that don’t \ 
support the TCP_NODELAY socket option.
bpo-1596321: Fix the threading._shutdown() function when the threading module \ 
was imported first from a thread different than the main thread: no longer log \ 
an error at Python exit.
bpo-45274: Fix a race condition in the Thread.join() method of the threading \ 
module. If the function is interrupted by a signal and the signal handler raises \ 
an exception, make sure that the thread remains in a consistent state to prevent \ 
a deadlock. Patch by Victor Stinner.
bpo-45238: Fix unittest.IsolatedAsyncioTestCase.debug(): it runs now \ 
asynchronous methods and callbacks.
bpo-36674: unittest.TestCase.debug() raises now a unittest.SkipTest if the class \ 
or the test method are decorated with the skipping decorator.
bpo-45235: Fix an issue where argparse would not preserve values in a provided \ 
namespace when using a subparser with defaults.
bpo-45234: Fixed a regression in copyfile(), copy(), copy2() raising \ 
FileNotFoundError when source is a directory, which should raise \ 
IsADirectoryError
bpo-45228: Fix stack buffer overflow in parsing J1939 network address.
bpo-45192: Fix the tempfile._infer_return_type function so that the dir argument \ 
of the tempfile functions accepts an object implementing the os.PathLike \ 
protocol.

Patch by Kyungmin Lee.
bpo-45160: When tracing a tkinter variable used by a ttk OptionMenu, callbacks \ 
are no longer made twice.
bpo-35474: Calling mimetypes.guess_all_extensions() with strict=False no longer \ 
affects the result of the following call with strict=True. Also, mutating the \ 
returned list no longer affects the global state.
bpo-45166: typing.get_type_hints() now works with Final wrapped in ForwardRef.
bpo-45097: Remove deprecation warnings about the loop argument in asyncio \ 
incorrectly emitted in cases when the user does not pass the loop argument.
bpo-45081: Fix issue when dataclasses that inherit from typing.Protocol \ 
subclasses have wrong __init__. Patch provided by Yurii Karabas.
bpo-24444: Fixed an error raised in argparse help display when help for an \ 
option is set to 1+ blank spaces or when choices arg is an empty container.
bpo-45021: Fix a potential deadlock at shutdown of forked children when using \ 
concurrent.futures module
bpo-45030: Fix integer overflow in pickling and copying the range iterator.
bpo-39039: tarfile.open raises ReadError when a zlib error occurs during file \ 
extraction.
bpo-44594: Fix an edge case of ExitStack and AsyncExitStack exception chaining. \ 
They will now match with block behavior when __context__ is explicitly set to \ 
None when the exception is in flight.
Documentation
bpo-45726: Improve documentation for functools.singledispatch() and \ 
functools.singledispatchmethod.
bpo-45680: Amend the docs on GenericAlias objects to clarify that non-container \ 
classes can also implement __class_getitem__. Patch contributed by Alex Waygood.
bpo-45655: Add a new “relevant PEPs” section to the top of the documentation \ 
for the typing module. Patch by Alex Waygood.
bpo-45604: Add level argument to multiprocessing.log_to_stderr function docs.
bpo-45464: Mention in the documentation of Built-in Exceptions that inheriting \ 
from multiple exception types in a single subclass is not recommended due to \ 
possible memory layout incompatibility.
bpo-45449: Add note about PEP 585 in collections.abc.
bpo-45516: Add protocol description to the importlib.abc.Traversable documentation.
bpo-20692: Add Programming FAQ entry explaining that int literal attribute \ 
access requires either a space after or parentheses around the literal.
bpo-45216: Remove extra documentation listing methods in difflib. It was \ 
rendering twice in pydoc and was outdated in some places.
Tests
bpo-45578: Add tests for dis.distb()
bpo-45577: Add subtests for all pickle protocols in test_zoneinfo.
bpo-43592: test.libregrtest now raises the soft resource limit for the maximum \ 
number of file descriptors when the default is too low for our test suite as was \ 
often the case on macOS.

bpo-45209: Fix UserWarning: resource_tracker warning in \ 
_test_multiprocessing._TestSharedMemory.test_shared_memory_cleaned_after_process \ 
_termination
bpo-45195: Fix test_readline.test_nonascii(): sometimes, the newline character \ 
is not written at the end, so don’t expect it in the output. Patch by Victor \ 
Stinner.
bpo-45156: Fixes infinite loop on unittest.mock.seal() of mocks created by \ 
create_autospec().
bpo-45042: Fixes that test classes decorated with \ 
@hashlib_helper.requires_hashdigest were skipped all the time.
Build
bpo-43158: setup.py now uses values from configure script to build the _uuid \ 
extension module. Configure now detects util-linux’s libuuid, too.
bpo-45571: Modules/Setup now use PY_CFLAGS_NODIST instead of PY_CFLAGS to \ 
compile shared modules.
bpo-45532: Update sys.version to use main as fallback information. Patch by \ 
Jeong YunWon.
bpo-45405: Prevent internal configure error when running configure with recent \ 
versions of non-Apple clang. Patch by David Bohman.
bpo-45220: Avoid building with the Windows 11 SDK previews automatically. This \ 
may be overridden by setting the DefaultWindowsSDKVersion environment variable \ 
before building.
Windows
bpo-45337: venv now warns when the created environment may need to be accessed \ 
at a different path, due to redirections, links or junctions. It also now \ 
correctly installs or upgrades components when the alternate path is required.

Tk 8.6.11 provided by python.org macOS installers. Patch by Marc Culler of the \ 
Tk project.
IDLE

file has already been buffered.
bpo-44751: Remove crypt.h include from the public Python.h header.
