python310 py310-html-docs: updated to 3.10.5

Python 3.10.5 final

Core and Builtins

gh-93418: Fixed an assert where an f-string has an equal sign ‘=’ following \ 
an expression, but there’s no trailing brace. For example, f”{i=”.

gh-91924: Fix __ltrace__ debug feature if the stdout encoding is not UTF-8. \ 
Patch by Victor Stinner.

gh-93061: Backward jumps after async for loops are no longer given dubious line \ 
numbers.

gh-93065: Fix contextvars HAMT implementation to handle iteration over deep trees.

The bug was discovered and fixed by Eli Libman. See MagicStack/immutables#84 for \ 
more details.

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.

gh-91421: Fix a potential integer overflow in _Py_DecodeUTF8Ex.

bpo-47212: Raise IndentationError instead of SyntaxError for a bare except with \ 
no following indent. Improve SyntaxError locations for an un-parenthesized \ 
generator used as arguments. Patch by Matthieu Dartiailh.

bpo-47182: Fix a crash when using a named unicode character like "\N{digit \ 
nine}" after the main interpreter has been initialized a second time.

bpo-46775: Some Windows system error codes(>= 10000) are now mapped into the \ 
correct errno and may now raise a subclass of OSError. Patch by Dong-hee Na.

bpo-47117: Fix a crash if we fail to decode characters in interactive mode if \ 
the tokenizer buffers are uninitialized. Patch by Pablo Galindo.

bpo-39829: Removed the __len__() call when initializing a list and moved \ 
initializing to list_extend. Patch by Jeremiah Pascual.

bpo-46962: Classes and functions that unconditionally declared their docstrings \ 
ignoring the --without-doc-strings compilation flag no longer do so.

The classes affected are ctypes.UnionType, pickle.PickleBuffer, \ 
testcapi.RecursingInfinitelyError, and types.GenericAlias.

The functions affected are 24 methods in ctypes.

Patch by Oleg Iarygin.

bpo-36819: Fix crashes in built-in encoders with error handlers that return \ 
position less or equal than the starting position of non-encodable characters.

Library

gh-93156: Accessing the pathlib.PurePath.parents sequence of an absolute path \ 
using negative index values produced incorrect results.

gh-89973: Fix re.error raised in fnmatch if the pattern contains a character \ 
range with upper bound lower than lower bound (e.g. [c-a]). Now such ranges are \ 
interpreted as empty ranges.

gh-93010: In a very special case, the email package tried to append the \ 
nonexistent InvalidHeaderError to the defect list. It should have been \ 
InvalidHeaderDefect.

gh-92839: Fixed crash resulting from calling bisect.insort() or \ 
bisect.insort_left() with the key argument not equal to None.

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 threading.Condition.notify().

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-91401: Provide a fail-safe way to disable subprocess use of vfork() via a \ 
private subprocess._USE_VFORK attribute. While there is currently no known need \ 
for this, if you find a need please only set it to False. File a CPython issue \ 
as to why you needed it and link to that from a comment in your code. This \ 
attribute is documented as a footnote in 3.11.

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 output.

gh-91734: Fix OSS audio support on Solaris.

gh-91700: Compilation of regular expression containing a conditional expression \ 
(?(group)...) now raises an appropriate re.error if the group number refers to \ 
not defined group. Previously an internal RuntimeError was raised.

gh-91676: Fix unittest.IsolatedAsyncioTestCase to shutdown 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-47260: Fix os.closerange() potentially being a no-op in a Linux seccomp sandbox.

bpo-39064: zipfile.ZipFile now raises zipfile.BadZipFile instead of ValueError \ 
when reading a corrupt zip file in which the central directory offset is \ 
negative.

bpo-47151: When subprocess tries to use vfork, it now falls back to fork if \ 
vfork returns an error. This allows use in situations where vfork isn’t \ 
allowed by the OS kernel.

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.

bpo-43323: Fix errors in the email module if the charset itself contains \ 
undecodable/unencodable characters.

bpo-47101: hashlib.algorithms_available now lists only algorithms that are \ 
provided by activated crypto providers on OpenSSL 3.0. Legacy algorithms are not \ 
listed unless the legacy provider has been loaded into the default OSSL context.

bpo-46787: Fix concurrent.futures.ProcessPoolExecutor exception memory leak

bpo-45393: Fix the formatting for await x and not x in the operator precedence \ 
table when using the help() system.

bpo-46415: Fix ipaddress.ip_{address,interface,network} raising TypeError \ 
instead of ValueError if given invalid tuple as address parameter.

bpo-28249: Set doctest.DocTest.lineno to None when object does not have __doc__.

bpo-45138: Fix a regression in the sqlite3 trace callback where bound parameters \ 
were not expanded in the passed statement string. The regression was introduced \ 
in Python 3.10 by bpo-40318. Patch by Erlend E. Aasland.

bpo-44493: Add missing terminated NUL in sockaddr_un’s length

This was potentially observable when using non-abstract AF_UNIX datagram sockets \ 
to processes written in another programming language.

bpo-42627: Fix incorrect parsing of Windows registry proxy settings

bpo-36073: Raise ProgrammingError instead of segfaulting on recursive usage of \ 
cursors in sqlite3 converters. Patch by Sergey Fedoseev.

Documentation

shutil.unpack_archive()
gh-91547: Remove “Undocumented modules” page.
bpo-44347: Clarify the meaning of dirs_exist_ok, a kwarg of shutil.copytree().
bpo-38668: Update the introduction to documentation for os.path to remove \ 
warnings that became irrelevant after the implementations of PEP 383 and PEP \ 
529.
bpo-47138: Pin Jinja to a version compatible with Sphinx version 3.2.1.
bpo-46962: All docstrings in code snippets are now wrapped into PyDoc_STR() to \ 
follow the guideline of PEP 7’s Documentation Strings paragraph. Patch by Oleg \ 
Iarygin.
bpo-26792: Improve the docstrings of runpy.run_module() and runpy.run_path(). \ 
Original patch by Andrew Brezovsky.
bpo-40838: Document that inspect.getdoc(), inspect.getmodule(), and \ 
inspect.getsourcefile() might return None.
bpo-45790: Adjust inaccurate phrasing in Defining Extension Types: Tutorial \ 
about the ob_base field and the macros used to access its contents.
bpo-42340: Document that in some circumstances KeyboardInterrupt may cause the \ 
code to enter an inconsistent state. Provided a sample workaround to avoid it if \ 
needed.
bpo-41233: Link the errnos referenced in Doc/library/exceptions.rst to their \ 
respective section in Doc/library/errno.rst, and vice versa. Previously this was \ 
only done for EINTR and InterruptedError. Patch by Yan “yyyyyyyan” Orestes.
bpo-38056: Overhaul the Error Handlers documentation in codecs.
bpo-13553: Document tkinter.Tk args.

gh-92886: Fixing tests that fail when running with optimizations (-O) in \ 
test_imaplib.py.
gh-92670: Skip test_shutil.TestCopy.test_copyfile_nonexistent_dir test on AIX as \ 
the test uses a trailing slash to force the OS consider the path as a directory, \ 
but on AIX the trailing slash has no effect and is considered as a file.
gh-91904: Fix initialization of PYTHONREGRTEST_UNICODE_GUARD which prevented \ 
running regression tests on non-UTF-8 locale.
gh-91607: Fix test_concurrent_futures to test the correct multiprocessing start \ 
method context in several cases where the test logic mixed this up.
bpo-47205: Skip test for sched_getaffinity() and sched_setaffinity() error case \ 
on FreeBSD.
bpo-47104: Rewrite asyncio.to_thread() tests to use unittest.IsolatedAsyncioTestCase.
bpo-29890: Add tests for ipaddress.IPv4Interface and ipaddress.IPv6Interface \ 
construction with tuple arguments. Original patch and tests by louisom.

by using errors codes returned by FindFirstFileW() when appropriate in \ 
win32_xstat_impl.
bpo-40859: Update Windows build to use xz-5.2.5

Tools/Demos
