python310 py310-html-docs: updated to 3.10.3
Python 3.10.3 final
Core and Builtins
bpo-46940: Avoid overriding AttributeError metadata information for nested \
attribute access calls. Patch by Pablo Galindo.
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-46820: Fix parsing a numeric literal immediately (without spaces) followed \
by “not in” keywords, like in 1not in x. Now the parser only emits a \
warning, not a syntax error.
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-46724: Make sure that all backwards jumps use the JUMP_ABSOLUTE instruction, \
rather than JUMP_FORWARD with an argument of (2**32)+offset.
bpo-46732: Correct the docstring for the __bool__() method. Patch by Jelle Zijlstra.
bpo-46707: Avoid potential exponential backtracking when producing some syntax \
errors involving lots of brackets. Patch by Pablo Galindo.
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-45773: Remove two invalid “peephole” optimizations from the bytecode \
compiler.
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.
bpo-46070: Py_EndInterpreter() now explicitly untracks all objects currently \
tracked by the GC. Previously, if an object was used later by another \
interpreter, calling PyObject_GC_UnTrack() on the object crashed if the previous \
or the next object of the PyGC_Head structure became a dangling pointer. Patch \
by Victor Stinner.
bpo-46339: Fix a crash in the parser when retrieving the error text for \
multi-line f-strings expressions that do not start in the first line of the \
string. Patch by Pablo Galindo
bpo-46240: Correct the error message for unclosed parentheses when the tokenizer \
doesn’t reach the end of the source when the error is reported. Patch by Pablo \
Galindo
bpo-46091: Correctly calculate indentation levels for lines with whitespace \
character that are ended by line continuation characters. Patch by Pablo Galindo
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-23325: The signal module no longer assumes that SIG_IGN and SIG_DFL are \
small int singletons.
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-46643: In typing.get_type_hints(), support evaluating stringified \
ParamSpecArgs and ParamSpecKwargs annotations. Patch by Gregory Beauregard.
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-46676: Make typing.ParamSpec args and kwargs equal to themselves. Patch by \
Gregory Beauregard.
bpo-46672: Fix NameError in asyncio.gather() when initial type check fails.
bpo-46655: In typing.get_type_hints(), support evaluating bare stringified \
TypeAlias annotations. Patch by Gregory Beauregard.
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-46521: Fix a bug in the codeop module that was incorrectly identifying \
invalid code involving string quotes as valid code.
bpo-46581: Brings ParamSpec propagation for GenericAlias in line with \
Concatenate (and others).
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-45173: Note the configparser deprecations will be removed in Python 3.12.
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-46246: Add missing __slots__ to importlib.metadata.DeprecatedList. Patch by \
Arie Bovenberg.
bpo-46266: Improve day constants in calendar.
Now all constants (MONDAY … SUNDAY) are documented, tested, and added to __all__.
bpo-46232: The ssl module now handles certificates with bit strings in DN correctly.
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-26552: Fixed case where failing asyncio.ensure_future() did not close the \
coroutine. Patch by Kumar Aditya.
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.
bpo-44791: Fix substitution of ParamSpec in Concatenate with different parameter \
expressions. Substitution with a list of types returns now a tuple of types. \
Substitution with Concatenate returns now a Concatenate with concatenated lists \
of arguments.
bpo-14156: argparse.FileType now supports an argument of ‘-’ in binary mode, \
returning the .buffer attribute of sys.stdin/sys.stdout as appropriate. Modes \
including ‘x’ and ‘a’ are treated equivalently to ‘w’ when argument \
is ‘-’. Patch contributed by Josh Rosenberg
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-46678: The function make_legacy_pyc in Lib/test/support/import_helper.py no \
longer fails when PYTHONPYCACHEPREFIX is set to a directory on a different \
device from where tempfiles are stored.
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.

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-47032: Ensure Windows install builds fail correctly with a non-zero exit \
code when part of the build fails.
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.
Windows

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.
C API
bpo-46433: The internal function _PyType_GetModuleByDef now correctly handles \

Pablo Galindo.
bpo-46006: Fix a regression when a type method like __init__() is modified in a \
subinterpreter. Fix a regression in _PyUnicode_EqualToASCIIId() and type \
update_slot(). Revert the change which made the Unicode dictionary of interned \
strings compatible with subinterpreters: the internal interned dictionary is \
shared again by all interpreters. Patch by Victor Stinner.
bpo-46085: Fix iterator cache mechanism of OrderedDict.
bpo-46110: Add a maximum recursion check to the PEG parser to avoid stack \
overflow. Patch by Pablo Galindo
bpo-46054: Fix parser error when parsing non-utf8 characters in source files. \
Patch by Pablo Galindo.

by the symbol table. Patch by Pablo Galindo.
bpo-46025: Fix a crash in the atexit module involving functions that unregister \
themselves before raising exceptions. Patch by Pablo Galindo.
bpo-46009: Restore behavior from 3.9 and earlier when sending non-None to newly \
started generator. In 3.9 this did not affect the state of the generator. In \
3.10.0 and 3.10.1 gen_func().send(0) is equivalent to \
gen_func().throw(TypeError(...) which exhausts the generator. In 3.10.2 onward, \
the behavior has been reverted to that of 3.9.
bpo-46000: Improve compatibility of the curses module with NetBSD curses.
bpo-46004: Fix the SyntaxError location for errors involving for loops with \
invalid targets. Patch by Pablo Galindo

(importlib_metadata 4.8.3).
bpo-26952: argparse raises ValueError with clear message when trying to render \
usage for an empty mutually-exclusive group. Previously it raised a cryptic \
IndexError.
bpo-27718: Fix help for the signal module. Some functions (e.g. signal() and \
getsignal()) were omitted.
bpo-46032: The registry() method of functools.singledispatch() functions checks \
now the first argument or the first parameter annotation and raises a TypeError \
if it is not supported. Previously unsupported “types” were ignored (e.g. \
typing.List[int]) or caused an error at calling time (e.g. list[int]).
bpo-46018: Ensure that math.expm1() does not raise on underflow.
bpo-45755: typing generic aliases now reveal the class attributes of the \
original generic class when passed to dir(). This was the behavior up to Python \
3.6, but was changed in 3.7-3.9.
bpo-13236: unittest.TextTestResult and unittest.TextTestRunner flush now the \
output stream more often.
bpo-42378: Fixes the issue with log file being overwritten when \
logging.FileHandler is used in atexit with filemode set to 'w'. Note this will \
cause the message in atexit not being logged if the log stream is already closed \
due to shutdown of logging.

memory with junk byte.
bpo-46150: Now fakename in test_pathlib.PosixPathTest.test_expanduser is checked \
to be non-existent.
bpo-46129: Rewrite asyncio.locks tests with unittest.IsolatedAsyncioTestCase usage.
bpo-46114: Fix test case for OpenSSL 3.0.1 version. OpenSSL 3.0 uses 0xMNN00PP0L.
Build
bpo-46263: configure no longer sets MULTIARCH on FreeBSD platforms.
bpo-46106: Updated OpenSSL to 1.1.1m in Windows builds, macOS installer builds, \
and CI. Patch by Kumar Aditya.
