Log Message:
python38: updated to 3.8.10

Python 3.8.10 final

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-43472: Ensures interpreter-level audit hooks receive the \ 
cpython.PyInterpreterState_New event when called through the _xxsubinterpreters \ 
module.
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.

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-34463: Fixed discrepancy between traceback and the interpreter in formatting \ 
of SyntaxError with lineno not set (traceback was changed to match interpreter).
bpo-41735: Fix thread locks in zlib module may go wrong in rare case. Patch by \ 
Ma Lin.
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-36470: Fix dataclasses with InitVars and replace(). Patch by Claudiu Popa.
bpo-28577: The hosts method on 32-bit prefix length IPv4Networks and 128-bit \ 
prefix IPv6Networks now returns a list containing the single Address instead of \ 
an empty list.
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-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-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.

Windows
bpo-35306: Avoid raising errors from pathlib.Path.exists() when passed an \ 
invalid filename.
bpo-38822: Fixed os.stat() failing on inaccessible directories with a trailing \ 
slash, rather than falling back to the parent directory’s metadata. This \ 
implicitly affected os.path.exists() and os.path.isdir().
bpo-26227: Fixed decoding of host names in socket.gethostbyaddr() and \ 
socket.gethostbyname_ex().
bpo-43745: Actually updates Windows release to OpenSSL 1.1.1k. Earlier releases \ 
were mislabelled and actually included 1.1.1i again.
bpo-43492: Upgrade Windows installer to use SQLite 3.35.5.

macOS
bpo-44009: Provide “python3.x-intel64” executable to allow reliably forcing \ 
macOS universal2 framework builds to run under Rosetta 2 Intel-64 emulation on \ 
Apple Silicon Macs. This can be useful for testing or when universal2 wheels are \ 
not yet available.
bpo-41100: As of 3.8.10, Python now supports building and running on macOS 11 \ 
(Big Sur) and on Apple Silicon Macs (based on the ARM64 architecture). A new \ 
universal build variant, universal2, is also available to natively support both \ 
ARM64 and Intel 64 in one set of executables. This backport from Python 3.9 does \ 
not include support for “weaklinking”; to support a range of macOS versions, \ 
continue to target for and build on the oldest version in the range; for 3.8.x, \ 
the universal2 variant is only useful on macOS 11 or later.
bpo-43492: Update macOS installer to use SQLite 3.35.4.

IDLE
bpo-43655: IDLE dialog windows are now recognized as dialogs by window managers \ 
on macOS and X Window.

C API
bpo-43962: _PyInterpreterState_IDIncref() now calls \ 
_PyInterpreterState_IDInitref() and always increments id_refcount. Previously, \ 
calling _xxsubinterpreters.get_current() could create an id_refcount \ 
inconsistency when a _xxsubinterpreters.InterpreterID object was deallocated. \ 
Patch by Victor Stinner.
