Core and Builtins

    bpo-42268: Fail the configure step if the selected compiler doesn’t support memory sanitizer. Patch by Pablo Galindo

    bpo-45727: Refine the custom syntax error that suggests that a comma may be missing to trigger only when the expressions are detected between parentheses or brackets. Patch by Pablo Galindo

    bpo-45614: Fix traceback display for exceptions with invalid module name.

    bpo-45848: Allow the parser to obtain error lines directly from encoded files. Patch by Pablo Galindo

    bpo-45826: Fixed a crash when calling .with_traceback(None) on NameError. This occurs internally in unittest.TestCase.assertRaises().

    bpo-45822: Fixed a bug in the parser that was causing it to not respect PEP 263 coding cookies when no flags are provided. Patch by Pablo Galindo

    bpo-45820: Fix a segfault when the parser fails without reading any input. Patch by Pablo Galindo

    bpo-42540: Fix crash when os.fork() is called with an active non-default memory allocator.

    bpo-45738: Fix computation of error location for invalid continuation characters in the parser. Patch by Pablo Galindo.

    bpo-45773: Fix a compiler hang when attempting to optimize certain jump patterns.

    bpo-45716: Improve the SyntaxError message when using True, None or False as keywords in a function call. Patch by Pablo Galindo.

    bpo-45688: sys.stdlib_module_names now contains the macOS-specific module _scproxy.

    bpo-30570: Fixed a crash in issubclass() from infinite recursion when searching pathological __bases__ tuples.

    bpo-45521: Fix a bug in the obmalloc radix tree code. On 64-bit machines, the bug causes the tree to hold 46-bits of virtual addresses, rather than the intended 48-bits.

    bpo-45494: Fix parser crash when reporting errors involving invalid continuation characters. Patch by Pablo Galindo.

    bpo-45408: Fix a crash in the parser when reporting tokenizer errors that occur at the same time unclosed parentheses are detected. 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, 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).

    bpo-45056: Compiler now removes trailing unused constants from co_consts.


    bpo-27946: Fix possible crash when getting an attribute of class:xml.etree.ElementTree.Element simultaneously with replacing the attrib dict.

    bpo-37658: Fix issue when on certain conditions asyncio.wait_for() may allow a coroutine to complete successfully, but fail to return the result, potentially causing memory leaks or other issues.

    bpo-44649: Handle dataclass(slots=True) with a field that has default a default value, but for which init=False.

    bpo-45803: Added missing kw_only parameter to dataclasses.make_dataclass().

    bpo-45831: faulthandler can now write ASCII-only strings (like filenames and function names) with a single write() syscall when dumping a traceback. It reduces the risk of getting an unreadable dump when two threads or two processes dump a traceback to the same file (like stderr) at the same time. Patch by Victor Stinner.

    bpo-41735: Fix thread lock in zlib.Decompress.flush() method before PyObject_GetBuffer.

    bpo-45235: Reverted an argparse bugfix that caused regression in the handling of default arguments for subparsers. This prevented leaf level arguments from taking precedence over root level arguments.

    bpo-45765: In importlib.metadata, fix distribution discovery for an empty path.

    bpo-45757: Fix bug where dis produced an incorrect oparg when EXTENDED_ARG is followed by an opcode that does not use its argument.

    bpo-45644: In-place JSON file formatting using python3 -m json.tool infile infile now works correctly, previously it left the file empty. Patch by Chris Wesseling.

    bpo-45679: Fix caching of multi-value typing.Literal. Literal[True, 2] is no longer equal to Literal[1, 2].

    bpo-45664: Fix types.resolve_bases() and types.new_class() for types.GenericAlias instance as a base.

    bpo-45663: Fix dataclasses.is_dataclass() for dataclasses which are subclasses of types.GenericAlias.

    bpo-45662: Fix the repr of dataclasses.InitVar with a type alias to the built-in class, e.g. InitVar[list[int]].

    bpo-45438: Fix typing.Signature string representation for generic builtin types.

    bpo-45574: Fix warning about print_escape being unused.

    bpo-45581: sqlite3.connect() now correctly raises MemoryError if the underlying SQLite API signals memory error. Patch by Erlend E. Aasland.

    bpo-45557: pprint.pprint() now handles underscore_numbers correctly. Previously it was always setting it to False.

    bpo-45515: Add references to zoneinfo in the datetime documentation, mostly replacing outdated references to Change by Paul Ganssle.

    bpo-45475: Reverted optimization of iterating gzip.GzipFile, bz2.BZ2File, and lzma.LZMAFile (see bpo-43787) because it caused regression when user iterate them without having reference of them. Patch by Inada Naoki.

    bpo-45428: Fix a regression in py_compile when reading filenames from standard input.

    bpo-45467: Fix incremental decoder and stream reader in the “raw-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-45249: Fix the behaviour of traceback.print_exc() when displaying the caret when the end_offset in the exception is set to 0. Patch by Pablo Galindo

    bpo-45416: Fix use of asyncio.Condition with explicit asyncio.Lock objects, which was a regression due to removal of explicit loop arguments. Patch by Joongi Kim.

    bpo-45419: Correct interfaces on DegenerateFiles.Path.

    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-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-36674: unittest.TestCase.debug() raises now a unittest.SkipTest if the class or the test method are decorated with the skipping decorator.

    bpo-45228: Fix stack buffer overflow in parsing J1939 network address.
