python39 py39-html-docs: updated to 3.9.11

Python 3.9.11 final

Core and Builtins

bpo-46852: Rename the private undocumented float.__set_format__() method to \ 
float.__setformat__() to fix a typo introduced in Python 3.7. The method is only \ 
used by test_float. Patch by Victor Stinner.
bpo-46794: Bump up the libexpat version into 2.4.6
bpo-46762: Fix an assert failure in debug builds when a ‘<’, ‘>’, \ 
or ‘=’ is the last character in an f-string that’s missing a closing right \ 
brace.
bpo-46732: Correct the docstring for the __bool__() method. Patch by Jelle Zijlstra.
bpo-40479: Add a missing call to va_end() in Modules/_hashopenssl.c.
bpo-46615: When iterating over sets internally in setobject.c, acquire strong \ 
references to the resulting items from the set. This prevents crashes in \ 
corner-cases of various set operations where the set gets mutated.
bpo-43721: Fix docstrings of getter, setter, and deleter to 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 by Victor Stinner.
bpo-46383: Fix invalid signature of _zoneinfo’s module_free function to \ 
resolve a crash on wasm32-emscripten platform.

Library

bpo-43253: Fix a crash when closing transports where the underlying socket \ 
handle is already invalid on the Proactor event loop.
bpo-47004: Apply bugfixes from importlib_metadata 4.11.3, including bugfix for \ 
EntryPoint.extras, which was returning match objects and not the extras strings.
bpo-46985: Upgrade pip wheel bundled with ensurepip (pip 22.0.4)
bpo-46968: faulthandler: On Linux 5.14 and newer, dynamically 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 asyncio.Server. Patch by Stefan \ 
Zabka.
bpo-46932: Update bundled libexpat to 2.4.7
bpo-25707: Fixed a file leak in xml.etree.ElementTree.iterparse() when the \ 
iterator is not exhausted. Patch by Jacob Walls.
bpo-44886: Inherit asyncio proactor datagram transport from \ 
asyncio.DatagramTransport.
bpo-46827: Support UDP sockets in asyncio.loop.sock_connect() for selector-based \ 
event loops. Patch by Thomas Grainger.
bpo-46811: Make test suite support Expat >=2.4.5
bpo-46252: Raise TypeError if ssl.SSLSocket is passed to transport-based APIs.
bpo-46784: Fix libexpat symbols collisions with user dynamically loaded or \ 
statically linked libexpat in embedded Python.
bpo-39327: shutil.rmtree() can now work with VirtualBox shared folders when \ 
running from the guest operating-system.
bpo-46756: Fix a bug in urllib.request.HTTPPasswordMgr.find_user_password() and \ 
urllib.request.HTTPPasswordMgrWithPriorAuth.is_authenticated() which allowed to \ 
bypass authorization. For example, access to URI example.org/foobar was allowed \ 
if the user was authorized for URI example.org/foo.
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 provides a default \ 
xml.etree.ElementTree.TreeBuilder target as the Python implementation does.
bpo-46591: Make the IDLE doc URL on the About IDLE dialog clickable.
bpo-46400: expat: Update libexpat from 2.4.1 to 2.4.4
bpo-46487: Add the get_write_buffer_limits method to \ 
asyncio.transports.WriteTransport and to the SSL transport.
bpo-46539: In typing.get_type_hints(), support evaluating stringified ClassVar \ 
and Final annotations inside Annotated. Patch by Gregory Beauregard.
bpo-46491: Allow typing.Annotated to wrap typing.Final and typing.ClassVar. \ 
Patch by Gregory Beauregard.
bpo-46436: Fix command-line option -d/--directory in module http.server which is \ 
ignored when combined with command-line option --cgi. Patch by Géry Ogam.
bpo-41403: Make mock.patch() raise a TypeError with a relevant error message on \ 
invalid arg. Previously it allowed a cryptic AttributeError to escape.
bpo-46474: In importlib.metadata.EntryPoint.pattern, avoid potential REDoS by \ 
limiting ambiguity in consecutive whitespace.
bpo-46469: asyncio generic classes now return types.GenericAlias in \ 
__class_getitem__ instead of the same class.
bpo-46434: pdb now gracefully handles help when __doc__ is missing, for example \ 
when run with pregenerated optimized .pyc files.
bpo-46333: The __eq__() and __hash__() methods of typing.ForwardRef now honor \ 
the module parameter of typing.ForwardRef. Forward references from different \ 
modules are now differentiated.
bpo-43118: Fix a bug in inspect.signature() that was causing it to fail on some \ 
subclasses of classes with a __text_signature__ referencing module globals. \ 
Patch by Weipeng Hong.
bpo-21987: Fix an issue with tarfile.TarFile.getmember() getting a directory \ 
name with a trailing slash.
bpo-20392: Fix inconsistency with uppercase file extensions in \ 
MimeTypes.guess_type(). Patch by Kumar Aditya.
bpo-46080: Fix exception in argparse help text generation if a \ 
argparse.BooleanOptionalAction argument’s default is argparse.SUPPRESS and it \ 
has help specified. Patch by Felix Fontein.
bpo-44439: Fix .write() method of a member file in ZipFile, 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.
bpo-24959: Fix bug where unittest sometimes drops frames from tracebacks of \ 
exceptions raised in tests.

Documentation

bpo-46463: Fixes escape4chm.py script used when building the CHM documentation file

Tests

bpo-46913: Fix test_faulthandler.test_sigfpe() if Python is built with undefined \ 
behavior sanitizer (UBSAN): disable UBSAN on the faulthandler_sigfpe() function. \ 
Patch by Victor Stinner.
bpo-46708: Prevent default asyncio event loop policy modification warning after \ 
test_asyncio execution.
bpo-46616: Ensures test_importlib.test_windows cleans up registry keys after \ 
completion.
bpo-44359: test_ftplib now silently ignores socket errors to prevent logging \ 
unhandled threading exceptions. Patch by Victor Stinner.
bpo-46542: Fix a Python crash in test_lib2to3 when using Python built in debug \ 
mode: limit the recursion limit. Patch by Victor Stinner.
bpo-46576: test_peg_generator now disables compiler optimization when testing \ 
compilation of its own C extensions to significantly speed up the testing on \ 
non-debug builds of CPython.
bpo-46542: Fix test_json tests checking for RecursionError: modify these tests \ 
to use support.infinite_recursion(). Patch by Victor Stinner.
bpo-13886: Skip test_builtin PTY tests on non-ASCII characters if the readline \ 
module is loaded. The readline module changes input() behavior, but test_builtin \ 
is not intented to test the readline module. Patch by Victor Stinner.

Build

bpo-47024: Update OpenSSL to 1.1.1n for macOS installers and all Windows builds.
bpo-38472: Fix GCC detection in setup.py when cross-compiling. The C compiler is \ 
now run with LC_ALL=C. Previously, the detection failed with a German locale.
bpo-46513: configure no longer uses AC_C_CHAR_UNSIGNED macro and pyconfig.h no \ 
longer defines reserved symbol __CHAR_UNSIGNED__.
bpo-45925: Update Windows installer to use SQLite 3.37.2.
bpo-47032: Ensure Windows install builds fail correctly with a non-zero exit \ 
code when part of the build fails.

Windows

bpo-44549: Update bzip2 to 1.0.8 in Windows builds to mitigate CVE-2016-3189 and \ 
CVE-2019-12900
bpo-46948: Prevent CVE-2022-26488 by ensuring the Add to PATH option in the \ 
Windows installer uses the correct path when being repaired.
bpo-46638: Ensures registry virtualization is consistently disabled. For 3.10 \ 
and earlier, it remains enabled (some registry writes are protected), while for \ 
3.11 and later it is disabled (registry modifications affect all applications).
macOS
bpo-45925: Update macOS installer to SQLite 3.37.2.

IDLE

bpo-46630: Make query dialogs on Windows start with a cursor in the entry box.
bpo-45296: Clarify close, quit, and exit in IDLE. In the File menu, ‘Close’ \ 
and ‘Exit’ are now ‘Close Window’ (the current one) and ‘Exit’ is \ 
now ‘Exit IDLE’ (by closing all windows). In Shell, ‘quit()’ and \ 
‘exit()’ mean ‘close Shell’. If there are no other windows, this also \ 
exits IDLE.
bpo-45447: Apply IDLE syntax highlighting to pyi files. Patch by Alex Waygood \ 
and Terry Jan Reedy.
