------------------------------------------------------------------- Thu Nov 14 07:06:20 UTC 2024 - Matej Cepl - Remove -IVendor/ from python-config boo#1231795 ------------------------------------------------------------------- Mon Nov 11 14:37:12 UTC 2024 - Matej Cepl - Require exact clang18 and llvm18, because apparently CPython is not ready for 19 yet (gh#python/cpython!125499). ------------------------------------------------------------------- Wed Oct 16 07:00:15 UTC 2024 - Matej Cepl - Update to the first development version of 3.14.0a1. Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far: - PEP 649: deferred evaluation of annotations - Improved error messages - Upstream doesn't sign tarballs with GPG anymore, but uses sigstore. Remove python.keyring. - Patches rebased and refreshed: - CVE-2023-52425-libexpat-2.6.0-backport-15.6.patch - bpo-31046_ensurepip_honours_prefix.patch - fix-test-recursion-limit-15.6.patch - python-3.3.0b1-fix_date_time_compiler.patch - Add patch to fix build: - gh125535-Lib_IntVector_Intrinsics_vec128.patch (gh#python/cpython#125535) - With python311-Sphinx we don't need no-skipif-doctests.patch any more. - Binary module _opcode is not build any more (gh#python/cpython!121555) - Add fix_test_ftp_error.patch to mark test_ftp_error as requiring network access, and explicitly declare we have no network. - Add fix_test_generated_data.patch to skip failing test (gh#python/cpython#121938). - Fix version number to 3.14.0~a1 ------------------------------------------------------------------- Thu Oct 10 11:18:19 UTC 2024 - Matej Cepl - Add warning about no-GIL builds being experimental. ------------------------------------------------------------------- Tue Oct 8 07:08:34 UTC 2024 - Matej Cepl - Update to 3.13.0: Major new features of the 3.13 series, compared to 3.12 Some of the new major new features and changes in Python 3.13 are: - New features - A new and improved interactive interpreter, based on PyPy's, featuring multi-line editing and color support, as well as colorized exception tracebacks. - An experimental free-threaded build mode, which disables the Global Interpreter Lock, allowing threads to run more concurrently. The build mode is available as an experimental feature in the Windows and macOS installers as well. - A preliminary, experimental JIT, providing the ground work for significant performance improvements. - The locals() builtin function (and its C equivalent) now has well-defined semantics when mutating the returned mapping, which allows debuggers to operate more consistently. - A modified version of mimalloc is now included, optional but enabled by default if supported by the platform, and required for the free-threaded build mode. - Docstrings now have their leading indentation stripped, reducing memory use and the size of .pyc files. (Most tools handling docstrings already strip leading indentation.) - The dbm module has a new dbm.sqlite3 backend that is used by default when creating new files. - WASI is now a Tier 2 supported platform. Emscripten is no longer an officially supported platform (but Pyodide continues to support Emscripten). - Typing - Support for type defaults in type parameters. - A new type narrowing annotation, typing.TypeIs. - A new annotation for read-only items in TypeDicts. - A new annotation for marking deprecations in the type system. - Removals and new deprecations - PEP 594 (Removing dead batteries from the standard library) scheduled removals of many deprecated modules: aifc, audioop, chunk, cgi, cgitb, crypt, imghdr, mailcap, msilib, nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau, telnetlib, uu, xdrlib, lib2to3. - Many other removals of deprecated classes, functions and methods in various standard library modules. - C API removals and deprecations. (Some removals present in alpha 1 were reverted in alpha 2, as the removals were deemed too disruptive at this time.) - New deprecations, most of which are scheduled for removal from Python 3.15 or 3.16. - For more details on the changes to Python 3.13, see What's new in Python 3.13 in the documentation. ------------------------------------------------------------------- Tue Oct 1 15:40:31 UTC 2024 - Matej Cepl - Update to 3.13.0~rc3: - The most important change is rolling back the incremental cyclic garbage collector (GC), which was added in one of the alpha releases.

Patch By Donghee Na. - gh-118836: Fix an AssertionError when building with --enable-experimental-jit and the compiler emits a SHT_NOTE section. - gh-118943: Fix a possible race condition affecting parallel builds configured with --enable-experimental-jit, in which compilation errors could be caused by an incompletely-generated header file. - Windows - gh-119679: Ensures correct import libraries are included in Windows installs. - gh-119690: Adds Unicode support and fixes audit events for _winapi.CreateNamedPipe. - gh-111201: Add support for new pyrepl on Windows - gh-119070: Fixes py.exe handling of shebangs like /usr/bin/env python3.12, which were previously interpreted as python3.exe instead of python3.12.exe. - gh-117505: Fixes an issue with the Windows installer not running ensurepip in a fully isolated environment. This could cause unexpected interactions with the user site-packages. - gh-118209: Avoid crashing in mmap on Windows when the mapped memory is inaccessible due to file system errors or access violations. - gh-116145: Updated bundled Tcl/Tk to 8.6.14. - C API - gh-119585: Fix crash when a thread state that was created by PyGILState_Ensure() calls a destructor that during PyThreadState_Clear() that calls back into PyGILState_Ensure() and PyGILState_Release(). This might occur when in the free-threaded build or when using thread-local variables whose destructors call PyGILState_Ensure(). - gh-119336: Restore the removed _PyLong_NumBits() function. It is used by the pywin32 project. Patch by Ethan Smith - gh-119247: Added Py_BEGIN_CRITICAL_SECTION_SEQUENCE_FAST and Py_END_CRITICAL_SECTION_SEQUENCE_FAST macros to make it possible to use PySequence_Fast APIs safely when free-threaded, and update str.join to work without the GIL using them. - gh-111389: Add PyHASH_MULTIPLIER constant: prime multiplier used in string and various other hashes. Patch by Victor Stinner. - gh-116984: Make mimalloc includes relative to the current file to avoid embedders or extensions needing to include Internal/mimalloc if they are already including internal CPython headers. - gh-118789: Restore _PyWeakref_ClearRef that was previously removed in Python 3.13 alpha 1. ------------------------------------------------------------------- Thu May 9 12:29:28 UTC 2024 - Matej Cepl - Use proper version name including tilda to separate pre-release version. https://en.opensuse.org/openSUSE:Package_versioning_guidelines ------------------------------------------------------------------- Thu May 9 08:18:00 UTC 2024 - Daniel Garcia - Update to 3.13.0b1: - Security - gh-116741: Update bundled libexpat to 2.6.2 - gh-117233: Detect BLAKE2, SHA3, Shake, & truncated SHA512 support in the OpenSSL-ish libcrypto library at build time. This allows hashlib to be used with libraries that do not to support every algorithm that upstream OpenSSL does. - Core and Builtins - gh-118414: Add instrumented opcodes to YIELD_VALUE assertion for tracing cases. - gh-117953: When a builtin or extension module is imported for the first time, while a subinterpreter is active, the module’s init function is now run by the main interpreter first before import continues in the subinterpreter. Consequently, single-phase init modules now fail in an isolated subinterpreter without the init function running under that interpreter, whereas before it would run under the subinterpreter before failing, potentially leaving behind global state and callbacks and otherwise leaving the module in an inconsistent state. - gh-117549: Don’t use designated initializer syntax in inline functions in internal headers. They cause problems for C++ or MSVC users who aren’t yet using the latest C++ standard (C++20). While internal, pycore_backoff.h, is included (indirectly, via pycore_code.h) by some key 3rd party software that does so for speed. - gh-95382: Improve performance of json.dumps() and json.dump() when using the argument indent. Depending on the data the encoding using json.dumps() with indent can be up to 2 to 3 times faster. - gh-116322: In --disable-gil builds, the GIL will be enabled while loading C extension modules. If the module indicates that it supports running without the GIL, the GIL will be disabled once loading is complete. Otherwise, the GIL will remain enabled for the remainder of the interpreter’s lifetime. This behavior does not apply if the GIL has been explicitly enabled or disabled with PYTHON_GIL or -Xgil. - gh-118513: Fix incorrect UnboundLocalError when two comprehensions in the same function both reference the same name, and in one comprehension the name is bound while in the other it’s an implicit global. - gh-118518: Allow the Linux perf support to work without frame pointers using perf’s advanced JIT support. The feature is activated when using the PYTHON_PERF_JIT_SUPPORT environment variable or when running Python with -Xperf_jit. Patch by Pablo Galindo. - gh-117514: Add sys._is_gil_enabled() function that returns whether the GIL is currently enabled. In the default build it always returns True because the GIL is always enabled. In the free-threaded build, it may return True or False. - gh-118164: Break a loop between the Python implementation of the decimal module and the Python code for integer to string conversion. Also optimize integer to string conversion for values in the range from 9_000 to 135_000 decimal digits. - gh-118473: Fix sys.set_asyncgen_hooks() not to be partially set when raising TypeError. - gh-118465: Compiler populates the new __firstlineno__ field on a class with the line number of the first line of the class definition. - gh-118492: Fix an issue where the type cache can expose a previously accessed attribute when a finalizer is run. - gh-117714: update async_generator.athrow().close() and async_generator.asend().close() to close their section of the underlying async generator - gh-111201: The interactive interpreter is now implemented in Python, which allows for a number of new features like colors, multiline input, history viewing, and paste mode. Contributed by Pablo Galindo, Łukasz Langa and Lysandros Nikolaou based on code from the PyPy project. - gh-74929: Implement PEP 667: converted FrameType.f_locals and PyFrame_GetLocals() to return a write-through proxy object when the frame refers to a function or comprehension. - gh-116767: Fix crash in compiler on ‘async with’ that has many context managers. - gh-118335: Change how to use the tier 2 interpreter. Instead of running Python with -X uops or setting the environment variable PYTHON_UOPS=1, this choice is now made at build time by configuring with --enable-experimental-jit=interpreter. - Beware! This changes the environment variable to enable or disable micro-ops to PYTHON_JIT. The old PYTHON_UOPS is no longer used. - gh-118306: Update JIT compilation to use LLVM 18 - gh-118160: Annotation scopes within classes can now contain comprehensions. However, such comprehensions are not inlined into their parent scope at runtime. Patch by Jelle Zijlstra. - gh-118272: Fix bug where generator.close does not free the generator frame’s locals. - gh-118216: Don’t consider __future__ imports with dots before the module name. - gh-118074: Make sure that the Executor objects in the COLD_EXITS array aren’t assumed to be GC-able (which would access bytes outside the object). - gh-107674: Lazy load frame line number to improve performance of tracing - gh-118082: Improve SyntaxError message for imports without names, like in from x import and import cases. It now points out to users that import expects at least one name after it. - gh-118090: Improve SyntaxError message for empty type param brackets. - gh-102511: Speed up os.path.splitroot() with a native implementation. - gh-117958: Added a get_jit_code() method to access JIT compiled machine code from the UOp Executor when the experimental JIT is enabled. Patch by Anthony Shaw. - gh-117901: Add option for compiler’s codegen to save nested instruction sequences for introspection. - gh-116622: Redirect stdout and stderr to system log when embedded in an Android app. - gh-109118: annotation scope within class scopes can now contain lambdas. - gh-117894: Prevent agen.aclose() objects being re-used after .throw(). - gh-117881: prevent concurrent access to an async generator via athrow().throw() or asend().throw() - gh-115874: Fixed a possible segfault during garbage collection of _asyncio.FutureIter objects - gh-117536: Fix a RuntimeWarning when calling agen.aclose().throw(Exception). - gh-117755: Fix mimalloc allocator for huge memory allocation (around 8,589,934,592 GiB) on s390x. Patch by Victor Stinner. - gh-117750: Fix issue where an object’s dict would get out of sync with the object’s internal values when being cleared. obj.__dict__.clear() now clears the internal values, but leaves the dict attached to the object. - gh-117431: Improve the performance of the following bytes and bytearray methods by adapting them to the METH_FASTCALL calling convention: count() find() index() rfind() rindex() - gh-117709: Speed up calls to str() with positional-only argument, by using the PEP 590 vectorcall calling convention. Patch by Erlend Aasland. - gh-117680: Give _PyInstructionSequence a Python interface and use it in tests. - gh-115776: Statically allocated objects are, by definition, immortal so must be marked as such regardless of whether they are in extension modules or not. - gh-117641: Speedup os.path.commonpath() on Unix. - gh-117636: Speedup os.path.join(). - gh-117607: Speedup os.path.relpath(). - gh-117385: Remove unhandled PY_MONITORING_EVENT_BRANCH and PY_MONITORING_EVENT_EXCEPTION_HANDLED events from sys.settrace(). - gh-116322: Extension modules may indicate to the runtime that they can run without the GIL. Multi-phase init modules do so by calling providing Py_MOD_GIL_NOT_USED for the Py_mod_gil slot, while single-phase init modules call PyUnstable_Module_SetGIL(mod, Py_MOD_GIL_NOT_USED) from their init function. - gh-116129: Implement PEP 696, adding support for defaults on type parameters. Patch by Jelle Zijlstra. - gh-93502: Add two new functions to the C-API, PyRefTracer_SetTracer() and PyRefTracer_GetTracer(), that allows to track object creation and destruction the same way the tracemalloc module does. Patch by Pablo Galindo - gh-107674: Improved the performance of sys.settrace() significantly - gh-95754: Improve the error message when a script shadowing a module from the standard library causes AttributeError to be raised. Similarly, improve the error message when a script shadowing a third party module attempts to access an attribute from that third party module while still initialising. - gh-99180: Elide uninformative traceback indicators in return and simple assignment statements. Patch by Pablo Galindo. - gh-105879: Allow the globals and locals arguments to exec() and eval() to be passed as keywords. - Library - gh-118418: A DeprecationWarning is now emitted if you fail to pass a value to the new type_params parameter of typing._eval_type() or typing.ForwardRef._evaluate(). (Using either of these private and undocumented functions is discouraged to begin with, but failing to pass a value to the type_params parameter may lead to incorrect behaviour on Python 3.12 or newer.) - gh-118660: Add an optional second type parameter to typing.ContextManager and typing.AsyncContextManager, representing the return types of __exit__() and __aexit__() respectively. This parameter defaults to bool | None. - gh-118650: The enum module allows method named _repr_* to be defined on Enum types. - gh-118648: Add type parameter defaults to typing.Generator and typing.AsyncGenerator. - gh-101137: Mime type text/x-rst is now supported by mimetypes. - gh-118164: The Python implementation of the decimal module could appear to hang in relatively small power cases (like 2**117) if context precision was set to a very high value. A different method to check for exactly representable results is used now that doesn’t rely on computing 10**precision (which could be effectively too large to compute). - gh-111744: breakpoint() and pdb.set_trace() now enter the debugger immediately after the call rather than before the next line is executed. - gh-118500: Add pdb support for zipapps - gh-118406: Add signature for sqlite3.Connection objects. - gh-101732: Use a Y2038 compatible openssl time function when available. - gh-118404: Fix inspect.signature() for non-comparable callables. - gh-118402: Fix inspect.signature() for the result of the functools.cmp_to_key() call. - gh-116622: On Android, sysconfig.get_platform now returns the format specified by PEP 738. - gh-118285: Allow to specify the signature of custom callable instances of extension type by the __text_signature__ attribute. Specify signatures of operator.attrgetter, operator.itemgetter, and operator.methodcaller instances. - gh-118314: Fix an edge case in binascii.a2b_base64() strict mode, where excessive padding is not detected when no padding is necessary. - gh-118271: Add the PhotoImage methods read() to read an image from a file and data() to get the image data. Add background and grayscale parameters to PhotoImage method write(). - gh-118225: Add the PhotoImage method copy_replace() to copy a region from one image to other image, possibly with pixel zooming and/or subsampling. Add from_coords parameter to PhotoImage methods copy(), zoom() and subsample(). Add zoom and subsample parameters to PhotoImage method copy(). - gh-118221: Fix a bug where sqlite3.Connection.iterdump() could fail if a custom row factory was used. Patch by Erlend Aasland. - gh-118013: Fix regression introduced in gh-103193 that meant that calling inspect.getattr_static() on an instance would cause a strong reference to that instance’s class to persist in an internal cache in the inspect module. This caused unexpected memory consumption if the class was dynamically created, the class held strong references to other objects which took up a significant amount of memory, and the cache contained the sole strong reference to the class. The fix for the regression leads to a slowdown in getattr_static(), but the function should still be significantly faster than it was in Python 3.11. Patch by Alex Waygood. - gh-118218: Speed up itertools.pairwise() in the common case by up to 1.8x. - gh-117486: Improve the behavior of user-defined subclasses of ast.AST. Such classes will now require no changes in the usual case to conform with the behavior changes of the ast module in Python 3.13. Patch by Jelle Zijlstra. - gh-90848: Fixed unittest.mock.create_autospec() to configure parent mock with keyword arguments. - gh-118168: Fix incorrect argument substitution when typing.Unpack is used with the builtin tuple. typing.Unpack now raises TypeError when used with certain invalid types. Patch by Jelle Zijlstra. - gh-118131: Add command-line interface for the random module. Patch by Hugo van Kemenade. - gh-118107: Fix zipimport reading of ZIP64 files with file entries that are too big or offset too far. - gh-117535: Change the unknown filename of warnings from sys to to clarify that it’s not a real filename. - gh-114053: Fix erroneous NameError when calling typing.get_type_hints() on a class that made use of PEP 695 type parameters in a module that had from __future__ import annotations at the top of the file. Patch by Alex Waygood. - gh-116931: Add parameter fileobj check for tarfile.TarFile.addfile() - gh-117995: Don’t raise DeprecationWarning when a sequence of parameters is used to bind indexed, nameless placeholders. See also gh-100668. - gh-80361: Fix TypeError in email.Message.get_payload() when the charset is RFC 2231 encoded. - gh-86650: Fix IndexError when parse some emails with invalid Message-ID (including one-off addresses generated by Microsoft Outlook). - gh-117691: Improve the error messages emitted by tarfile deprecation warnings relating to PEP 706. If a filter argument is not provided to extract() or extractall, the deprecation warning now points to the line in the user’s code where the relevant function was called. Patch by Alex Waygood. - gh-115060: Speed up pathlib.Path.glob() by omitting an initial is_dir() call. As a result of this change, glob() can no longer raise OSError. - gh-77102: site module now parses .pth file with UTF-8 first, and locale encoding if UnicodeDecodeError happened. It supported only locale encoding before. - gh-76785: We’ve exposed the low-level _interpreters module for the sake of the PyPI implementation of PEP 734. It was sometimes available as the _xxsubinterpreters module and was formerly used only for testing. For the most part, it should be considered an internal module, like _thread and _imp. See https://discuss.python.org/t/pep-734-multiple-interpreters-in-the-stdlib/41147/26. - gh-115060: Speed up pathlib.Path.glob() by not scanning directories for non-wildcard pattern segments. - gh-117727: Speed up pathlib.Path.iterdir() by using os.scandir() internally. - gh-117586: Speed up pathlib.Path.walk() by working with strings internally. - gh-117722: Change the new multi-separator support in asyncio.Stream.readuntil() to only accept tuples of separators rather than arbitrary iterables. - gh-117692: Fixes a bug when doctest.DocTestFinder was failing on wrapped builtin_function_or_method. - gh-117348: Largely restored import time performance of configparser by avoiding dataclasses. - gh-117663: Fix _simple_enum to detect aliases when multiple arguments are present but only one is the member value. - gh-117618: Support package.module as filename for break command of pdb - gh-102247: the status codes enum with constants in http.HTTPStatus are updated to include the names from RFC9110. This RFC includes some HTTP statuses previously only used for WEBDAV and assigns more generic names to them. - The old constants are preserved for backwards compatibility. - gh-117586: Speed up pathlib.Path.glob() by working with strings internally. - gh-117225: Add colour to doctest output. Patch by Hugo van Kemenade. - gh-117566: ipaddress.IPv6Address.is_loopback() will now return True for IPv4-mapped loopback addresses, i.e. addresses in the ::ffff:127.0.0.0/104 address space. - gh-117546: Fix issue where os.path.realpath() stopped resolving symlinks after encountering a symlink loop on POSIX. - gh-116720: Improved behavior of asyncio.TaskGroup when an external cancellation collides with an internal cancellation. For example, when two task groups are nested and both experience an exception in a child task simultaneously, it was possible that the outer task group would misbehave, because its internal cancellation was swallowed by the inner task group. - In the case where a task group is cancelled externally and also must raise an ExceptionGroup, it will now call the parent task’s cancel() method. This ensures that a asyncio.CancelledError will be raised at the next await, so the cancellation is not lost. - An added benefit of these changes is that task groups now preserve the cancellation count (asyncio.Task.cancelling()). - In order to handle some corner cases, asyncio.Task.uncancel() may now reset the undocumented _must_cancel flag when the cancellation count reaches zero. - gh-117516: Add typing.TypeIs, implementing PEP 742. Patch by Jelle Zijlstra. - gh-117503: Fix support of non-ASCII user names in bytes paths in os.path.expanduser() on Posix. - gh-117394: os.path.ismount() is now 2-3 times faster if the user has permissions. - gh-117313: Only treat '\n', '\r' and '\r\n' as line separators in re-folding the email messages. Preserve control characters '\v', '\f', '\x1c', '\x1d' and '\x1e' and Unicode line separators '\x85', '\u2028' and '\u2029' as is. - gh-117142: Convert _ctypes to multi-phase initialisation (PEP 489). - gh-66543: Add the mimetypes.guess_file_type() function which works with file path. Passing file path instead of URL in guess_type() is soft deprecated. - gh-68583: webbrowser CLI: replace getopt with argparse, add long options. Patch by Hugo van Kemenade. - gh-116871: Name suggestions for AttributeError and ImportError now only include underscored names if the original name was underscored. - gh-116023: Don’t show empty fields (value None or []) in ast.dump() by default. Add show_empty=False parameter to optionally show them. - gh-115961: Added name and mode attributes for compressed and archived file-like objects in modules bz2, lzma, tarfile and zipfile. The value of the mode attribute of gzip.GzipFile was changed from integer (1 or 2) to string ('rb' or 'wb'). The value of the mode attribute of the readable file-like object returned by zipfile.ZipFile.open() was changed from 'r' to 'rb'. - gh-82062: Fix inspect.signature() to correctly handle parameter defaults on methods in extension modules that use names defined in the module namespace. - gh-83856: Honor atexit for all multiprocessing start methods - gh-113081: Print colorized exception just like built-in traceback in pdb - gh-112855: Speed up pickling of pathlib.PurePath objects. Patch by Barney Gale. - gh-111744: Support opcode events in bdb - gh-109617: ncurses: fixed a crash that could occur on macOS 13 or earlier when Python was built with Apple Xcode 15’s SDK. - gh-83151: Enabled arbitrary statements and evaluations in pdb shell to access the local variables of the current frame, which made it possible for multi-scope code like generators or nested function to work. - gh-110209: Add __class_getitem__() to types.GeneratorType and types.CoroutineType for type hinting purposes. Patch by James Hilton-Balfe. - gh-108191: The types.SimpleNamespace now accepts an optional positional argument which specifies initial values of attributes as a dict or an iterable of key-value pairs. - gh-62090: Fix assertion errors caused by whitespace in metavars or SUPPRESS-ed groups in argparse by simplifying usage formatting. Patch by Ali Hamdan. - gh-102402: Adjust logging.LogRecord to use time.time_ns() and fix minor bug related to floating point math. - gh-100242: Bring pure Python implementation functools.partial.__new__ more in line with the C-implementation by not just always checking for the presence of the attribute 'func' on the first argument of partial. Instead, both the Python version and the C version perform an isinstance(func, partial) check on the first argument of partial. - gh-99730: HEAD requests are no longer upgraded to GET request during redirects in urllib. - gh-66410: Callbacks registered in the tkinter module now take arguments as various Python objects (int, float, bytes, tuple), not just str. To restore the previous behavior set tkinter module global wantobject to 1 before creating the Tk object or call the wantobject() method of the Tk object with argument 1. Calling it with argument 2 restores the current default behavior. - bpo-40943: Fix several IndexError when parse emails with truncated Message-ID, address, routes, etc, e.g. example@. - bpo-39324: Add mime type mapping for .md <-> text/markdown - bpo-18108: shutil.chown() now supports dir_fd and follow_symlinks keyword arguments. - bpo-30988: Fix parsing of emails with invalid address headers having a leading or trailing dot. Patch by tsufeki. - bpo-32839: Add the after_info() method for Tkinter widgets. - Documentation - gh-117928: The minimum Sphinx version required for the documentation is now 6.2.1. - Build - gh-118734: Fixes Windows build when invoked directly (not through the build.bat script) without specifying a value for UseTIER2. - gh-115119: The configure option --with-system-libmpdec now defaults to yes. The bundled copy of libmpdecimal will be removed in Python 3.15. - gh-117845: Fix building against recent libedit versions by detecting readline hook signatures in configure. - gh-116622: A testbed project was added to run the test suite on Android. - gh-117645: Increase WASI stack size from 512 KiB to 8 MiB and the initial memory from 10 MiB to 20 MiB. Patch by Victor Stinner. - gh-115119: configure now uses pkg-config to detect decimal dependencies if the --with-system-libmpdec option is given. - Windows - gh-115119: Update Windows installer to use libmpdecimal 4.0.0. - gh-118486: os.mkdir() now accepts mode of 0o700 to restrict the new directory to the current user. - gh-118347: Fixes launcher updates not being installed. - gh-118293: The multiprocessing module now passes the STARTF_FORCEOFFFEEDBACK flag when spawning processes to tell Windows not to change the mouse cursor. - gh-115009: Update Windows installer to use SQLite 3.45.3. - gh-90329: Suppress the warning displayed on virtual environment creation when the requested and created paths differ only by a short (8.3 style) name. Warnings will continue to be shown if a junction or symlink in the path caused the venv to be created in a different location than originally requested. - gh-117786: Fixes virtual environments not correctly launching when created from a Store install. - macOS - gh-115119: Update macOS installer to use libmpdecimal 4.0.0. - gh-114099: iOS preprocessor symbol usage was made compatible with older macOS SDKs. - gh-115009: Update macOS installer to use SQLite 3.45.3. - gh-91629: Use ~/.config/fish/conf.d configs and fish_add_path to set PATH when installing for the Fish shell. - IDLE - bpo-34774: Use user-selected color theme for Help => IDLE Doc. - C API - gh-118124: Fix Py_BUILD_ASSERT and Py_BUILD_ASSERT_EXPR for non-constant expressions: use static_assert() on C11 and newer. Patch by Victor Stinner. - gh-110850: Add “Raw” variant of PyTime functions PyTime_MonotonicRaw() PyTime_PerfCounterRaw() PyTime_TimeRaw() Patch by Victor Stinner. - gh-117987: Restore functions removed in Python 3.13 alpha 1: Py_SetPythonHome() Py_SetProgramName() PySys_SetArgvEx() PySys_SetArgv() Patch by Victor Stinner. - gh-117929: Restore removed PyEval_InitThreads() function. Patch by Victor Stinner. - gh-117534: Improve validation logic in the C implementation of datetime.datetime.fromisoformat() to better handle invalid years. Patch by Vlad Efanov. - gh-68114: Fixed skipitem()’s handling of the old ‘w’ and ‘w#’ formatters. These are no longer supported and now raise an exception if used. - gh-111997: Add a C-API for firing monitoring events. - Python 3.13.0 alpha 6: - Core and Builtins - gh-117648: Improve performance of os.path.join() and os.path.expanduser(). - gh-117584: Raise TypeError for non-paths in posixpath.relpath(). - gh-117494: Refactored the instruction sequence data structure out of compile.c into instruction_sequence.c. - gh-116968: Introduce a unified 16-bit backoff counter type (_Py_BackoffCounter), shared between the Tier 1 adaptive specializer and the Tier 2 optimizer. The API used for adaptive specialization counters is changed but the behavior is (supposed to be) identical. - The behavior of the Tier 2 counters is changed: There are no longer dynamic thresholds (we never varied these). All counters now use the same exponential backoff. The counter for JUMP_BACKWARD starts counting down from 16. The temperature in side exits starts counting down from 64. - gh-117431: Improve the performance of the following bytes and bytearray methods by adapting them to the METH_FASTCALL calling convention: endswith() startswith() - gh-117431: Improve the performance of the following str methods by adapting them to the METH_FASTCALL calling convention: count() endswith() find() index() rfind() rindex() startswith() - gh-117411: Move PyFutureFeatures to an internal header and make it private. - gh-109120: Added handle of incorrect star expressions, e.g f(3, *). Patch by Grigoryev Semyon - gh-117381: Fix error message for ntpath.commonpath(). - gh-117349: Optimise several functions in os.path. - gh-117335: Raise TypeError for non-sequences for ntpath.commonpath(). - gh-117266: Fix crashes for certain user-created subclasses of ast.AST. Such classes are now expected to set the _field_types attribute. - gh-99108: Updated the hashlib built-in HACL* project C code from upstream that we use for many implementations when they are not present via OpenSSL in a given build. This also avoids the rare potential for a C symbol name one definition rule linking issue. - gh-117108: Change the old space bit of objects in the young generation from 0 to gcstate->visited, so that any objects created during GC will have the old bit set correctly if they get moved into the old generation. - gh-117108: The cycle GC now chooses the size of increments based on the total heap size, instead of the rate of object creation. This ensures that it can keep up with growing heaps. - gh-117114: Make os.path.isdevdrive() available on all platforms. For those that do not offer Dev Drives, it will always return False. - gh-116735: For INSTRUMENTED_CALL_FUNCTION_EX, set arg0 to sys.monitoring.MISSING instead of None for CALL event. - gh-113964: Starting new threads and process creation through os.fork() are now only prevented once all non-daemon threads exit. - gh-116626: Ensure INSTRUMENTED_CALL_FUNCTION_EX always emits CALL - gh-116554: list.sort() now exploits more cases of partial ordering, particularly those with long descending runs with sub-runs of equal values. Those are recognized as single runs now (previously, each block of repeated values caused a new run to be created). - gh-114099: Added a Loader that can discover extension modules in an iOS-style Frameworks folder. - gh-115775: Compiler populates the new __static_attributes__ field on a class with the names of attributes of this class which are accessed through self.X from any function in its body. - gh-115776: The array of values, the PyDictValues struct is now embedded in the object during allocation. This provides better performance in the common case, and does not degrade as much when the object’s __dict__ is materialized. - gh-108362: Implement an incremental cyclic garbage collector. By collecting the old generation in increments, there is no need for a full heap scan. This can hugely reduce maximum pause time for programs with large heaps. - Reduce the number of generations from three to two. The old generation is split into two spaces, “visited” and “pending”. - Collection happens in two steps:: * An increment is formed from the young generation and a small part of the pending space. * This increment is scanned and the survivors moved to the end of the visited space. - When the collecting space becomes empty, the two spaces are swapped. - gh-109870: Dataclasses now calls exec() once per dataclass, instead of once per method being added. This can speed up dataclass creation by up to 20%. - gh-97901: Mime type text/rtf is now supported by mimetypes. - bpo-24612: Improve the SyntaxError that happens when ‘not’ appears after an operator. Patch by Pablo Galindo - Library - gh-117467: Preserve mailbox ownership when rewriting in mailbox.mbox.flush(). Patch by Tony Mountifield. - gh-114848: Raise FileNotFoundError when getcwd() returns ‘(unreachable)’, which can happen on Linux >= 2.6.36 with glibc < 2.27. - gh-117459: asyncio.asyncio.run_coroutine_threadsafe() now keeps the traceback of CancelledError, TimeoutError and InvalidStateError which are raised in the coroutine. - gh-117337: Deprecate undocumented glob.glob0() and glob.glob1() functions. Use glob.glob() and pass a directory to its root_dir argument instead. - gh-117348: Refactored configparser.RawConfigParser._read() to reduce cyclometric complexity and improve comprehensibility. - gh-66449: configparser.ConfigParser now accepts unnamed sections before named ones, if configured to do so. - gh-88014: In documentation of gzip.GzipFile in module gzip, explain data type of optional constructor argument mtime, and recommend mtime = 0 for generating deterministic streams. - gh-117310: Fixed an unlikely early & extra Py_DECREF triggered crash in ssl when creating a new _ssl._SSLContext if CPython was built implausibly such that the default cipher list is empty or the SSL library it was linked against reports a failure from its C SSL_CTX_set_cipher_list() API. - gh-117294: A DocTestCase now reports as skipped if all examples in the doctest are skipped. - gh-98966: In subprocess, raise a more informative message when stdout=STDOUT. - gh-117225: doctest: only print “and X failed” when non-zero, don’t pluralise “1 items”. Patch by Hugo van Kemenade. - gh-117205: Speed up compileall.compile_dir() by 20% when using multiprocessing by increasing chunksize. - gh-117178: Fix regression in lazy loading of self-referential modules, introduced in gh-114781. - gh-112383: Fix dis module’s handling of ENTER_EXECUTOR instructions. - gh-117182: Lazy-loading of modules that modify their own __class__ no longer reverts the __class__ to types.ModuleType. - gh-117084: Fix zipfile extraction for directory entries with the name containing backslashes on Windows. - gh-117110: Fix a bug that prevents subclasses of typing.Any to be instantiated with arguments. Patch by Chris Fu. - gh-109653: Deferred select imports in importlib.metadata and importlib.resources for a 14% speedup. - gh-70647: Start the deprecation period for the current behavior of datetime.datetime.strptime() and time.strptime() which always fails to parse a date string with a ValueError involving a day of month such as strptime("02-29", "%m-%d") when a year is not specified and the date happen to be February 29th. This should help avoid users finding new bugs every four years due to a natural mistaken assumption about the API when parsing partial date values. - gh-116987: Fixed inspect.findsource() for class code objects. - gh-114099: Modify standard library to allow for iOS platform differences. - gh-90872: On Windows, subprocess.Popen.wait() no longer calls WaitForSingleObject() with a negative timeout: pass 0 ms if the timeout is negative. Patch by Victor Stinner. - gh-116957: configparser: Don’t leave ConfigParser values in an invalid state (stored as a list instead of a str) after an earlier read raised DuplicateSectionError or DuplicateOptionError. - gh-115538: _io.WindowsConsoleIO now emit a warning if a boolean value is passed as a filedescriptor argument. - gh-90095: Ignore empty lines and comments in .pdbrc - gh-106531: Refreshed zipfile._path from zipp 3.18, providing better compatibility for PyPy, better glob performance for deeply nested zipfiles, and providing internal access to CompleteDirs.inject for use in other tests (like importlib.resources). - gh-63207: On Windows, time.time() now uses the GetSystemTimePreciseAsFileTime() clock to have a resolution better than 1 us, instead of the GetSystemTimeAsFileTime() clock which has a resolution of 15.6 ms. Patch by Victor Stinner. - gh-116764: Restore support of None and other false values in urllib.parse functions parse_qs() and parse_qsl(). Also, they now raise a TypeError for non-zero integers and non-empty sequences. - gh-116811: In PathFinder.invalidate_caches, delegate to MetadataPathFinder.invalidate_caches. - gh-116647: Fix recursive child in dataclasses - gh-113171: Fixed various false positives and false negatives in ipaddress.IPv4Address.is_private (see these docs for details) ipaddress.IPv4Address.is_global ipaddress.IPv6Address.is_private ipaddress.IPv6Address.is_global - Also in the corresponding ipaddress.IPv4Network and ipaddress.IPv6Network attributes. - Fixes bsc#1226448 (CVE-2024-4032). - gh-63283: In encodings.idna, any capitalization of the the ACE prefix (xn--) is now acceptable. Patch by Pepijn de Vos and Zackery Spytz. - gh-71042: Add platform.android_ver(), which provides device and OS information on Android. - gh-73468: Added new math.fma() function, wrapping C99’s fma() operation: fused multiply-add function. Patch by Mark Dickinson and Victor Stinner. - gh-116608: The importlib.resources functions is_resource(), open_binary(), open_text(), path(), read_binary(), and read_text() are un-deprecated, and support subdirectories via multiple positional arguments. The contents() function also allows subdirectories, but remains deprecated. - gh-116484: Change automatically generated tkinter.Checkbutton widget names to avoid collisions with automatically generated tkinter.ttk.Checkbutton widget names within the same parent widget. - gh-114314: In ctypes, ctype data is now stored in type objects directly rather than in a dict subclass. This is an internal change that should not affect usage. - gh-116401: Fix blocking os.fwalk() and shutil.rmtree() on opening named pipe. - gh-71052: Implement ctypes.util.find_library() on Android. - gh-90535: Fix support of interval values > 1 in logging.TimedRotatingFileHandler for when='MIDNIGHT' and when='Wx'. - gh-113308: Remove some internal protected parts from uuid: _has_uuid_generate_time_safe, _netbios_getnode, _ipconfig_getnode, and _load_system_functions. They were unused. - gh-115627: Fix the ssl module error handling of connection terminate by peer. It now throws an OSError with the appropriate error code instead of an EOFError. - gh-114847: Speed up os.path.realpath() on non-Windows platforms. - gh-114271: Fix a race in threading.Thread.join(). - threading._MainThread now always represents the main thread of the main interpreter. - PyThreadState.on_delete and PyThreadState.on_delete_data have been removed. - gh-113538: Add asyncio.Server.close_clients() and asyncio.Server.abort_clients() methods which allow to more forcefully close an asyncio server. - gh-85287: Changes Unicode codecs to return UnicodeEncodeError or UnicodeDecodeError, rather than just UnicodeError. - gh-113548: pdb now allows CLI arguments to pdb -m. - gh-112948: Make completion of pdb similar to Python REPL - gh-105866: Fixed _get_slots bug which caused error when defining dataclasses with slots and a weakref_slot. - gh-96471: Add asyncio.Queue termination with shutdown() method. - gh-89739: The zipimport module can now read ZIP64 files. - bpo-33533: asyncio.as_completed() now returns an object that is both an asynchronous iterator and plain iterator. The new asynchronous iteration pattern allows for easier correlation between prior tasks and their completed results. This is a closer match to concurrent.futures.as_completed()’s iteration pattern. Patch by Justin Arthur. - bpo-27578: inspect.getsource() (and related functions) work with empty module files, returning '\n' (or reasonable equivalent) instead of raising OSError. Patch by Kernc. - bpo-37141: Accept an iterable of separators in asyncio.StreamReader.readuntil(), stopping when one of them is encountered. - gh-66543: Make mimetypes.guess_type() properly parsing of URLs with only a host name, URLs containing fragment or query, and filenames with only a UNC sharepoint on Windows. Based on patch by Dong-hee Na. - bpo-15010: unittest.TestLoader.discover() now saves the original value of unittest.TestLoader._top_level_dir and restores it at the end of the call. - Documentation - gh-115977: Remove compatibilty references to Emscripten. - gh-114099: Add an iOS platform guide, and flag modules not available on iOS. - gh-91565: Changes to documentation files and config outputs to reflect the new location for reporting bugs - i.e. GitHub rather than bugs.python.org. - Tests - gh-83434: Disable JUnit XML output (--junit-xml=FILE command line option) in regrtest when hunting for reference leaks (-R option). Patch by Victor Stinner. - gh-117187: Fix XML tests for vanilla Expat <2.6.0. - gh-116333: Tests of TLS related things (error codes, etc) were updated to be more lenient about specific error message strings and behaviors as seen in the BoringSSL and AWS-LC forks of OpenSSL. - gh-117089: Consolidated tests for importlib.metadata in their own metadata package. - gh-115979: Update test_importlib so that it passes under WASI SDK 21. - gh-112536: Add –tsan to test.regrtest for running TSAN tests in reasonable execution times. Patch by Donghee Na. - gh-116307: Added import helper isolated_modules as CleanImport does not remove modules imported during the context.

After the deprecation period, st_ctime will be the metadata change time (or unavailable through DirEntry), and only st_birthtime will contain the creation time. - gh-116195: Improves performance of os.getppid() by using an alternate system API when available. Contributed by vxiiduu. - gh-88494: On Windows, time.monotonic() now uses the QueryPerformanceCounter() clock to have a resolution better than 1 us, instead of the GetTickCount64() clock which has a resolution of 15.6 ms. Patch by Victor Stinner. - gh-116773: Fix instances of <_overlapped.Overlapped object at 0xXXX> still has pending operation at deallocation, the process may crash. - gh-91227: Fix the asyncio ProactorEventLoop implementation so that sending a datagram to an address that is not listening does not prevent receiving any more datagrams. - gh-115119: Switched from vendored libmpdecimal code to a separately-hosted external package in the cpython-source-deps repository when building the _decimal module. - C API - gh-117642: Fix PEP 737 implementation for %#T and %#N. - gh-87193: _PyBytes_Resize() can now be called for bytes objects with reference count > 1, including 1-byte bytes objects. It creates a new bytes object and destroys the old one if it has reference count > 1. - gh-117021: Fix integer overflow in PyLong_AsPid() on non-Windows 64-bit platforms. - gh-115756: PyCode_GetFirstFree() is an ustable API now and has been renamed to PyUnstable_Code_GetFirstFree().

Patch by Victor Stinner. - gh-115754: In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references. Patch by Victor Stinner. - gh-115754: Add Py_GetConstant() and Py_GetConstantBorrowed() functions to get constants. For example, Py_GetConstant(Py_CONSTANT_ZERO) returns a strong reference to the constant zero. Patch by Victor Stinner. - gh-111696: Add support for %T, %T#, %N and %N# formats to PyUnicode_FromFormat(): format the fully qualified name of an object type and of a type: call PyType_GetModuleName().

It still exits with status code 0 otherwise. - gh-105858: Improve the constructors for ast nodes. Arguments of list types now default to an empty list if omitted, and optional fields default to None. AST nodes now have an __annotations__ attribute with the expected types of their attributes. Passing unrecognized extra arguments to AST nodes is deprecated and will become an error in Python 3.15. Omitting a required argument to an AST node is deprecated and will become an error in Python 3.15. Patch by Jelle Zijlstra. - gh-101860: Expose __name__ attribute on property. - gh-96497: Fix incorrect resolution of mangled class variables used in assignment expressions in comprehensions. - Library - gh-116600: Fix repr() for global Flag members. - gh-116349: platform.java_ver() is deprecated and will be removed in 3.15. It was largely untested, had a confusing API, and was only useful for Jython support. - gh-116143: Fix a race in pydoc _start_server, eliminating a window in which _start_server can return a thread that is “serving” but without a docserver set. - gh-116127: typing: implement PEP 705 which adds typing.ReadOnly support to typing.TypedDict. - gh-116325: typing: raise SyntaxError instead of AttributeError on forward references as empty strings. - gh-115957: When asyncio.TaskGroup.create_task is called on an inactive asyncio.TaskGroup, the given coroutine will be closed (which prevents a RuntimeWarning). - gh-115978: Disable preadv(), readv(), pwritev(), and writev() on WASI. Under wasmtime for WASI 0.2, these functions don’t pass test_posix (gh-bytecodealliance/wasmtime#7830). - gh-88352: Fix the computation of the next rollover time in the logging.TimedRotatingFileHandler handler. computeRollover() now always returns a timestamp larger than the specified time and works correctly during the DST change. doRollover() no longer overwrite the already rolled over file, saving from data loss when run at midnight or during repeated time at the DST change. - gh-87115: Set __main__.__spec__ to None when running a script with pdb - gh-76511: Fix UnicodeEncodeError in email.Message.as_string() that results when a message that claims to be in the ascii character set actually has non-ascii characters. Non-ascii characters are now replaced with the U+FFFD replacement character, like in the replace error handler. - gh-89547: Add support for nested typing special forms like Final[ClassVar[int]]. - gh-65824: Improve the less prompt in pydoc. - gh-116040: [Enum] fix by-value calls when second value is falsey; e.g. Cardinal(1, 0) - gh-115821: [Enum] Improve error message when calling super().__new__() in custom __new__. - gh-85644: Use the XDG_CURRENT_DESKTOP environment variable in webbrowser to check desktop. Prefer it to the deprecated GNOME_DESKTOP_SESSION_ID for GNOME detection. - gh-75988: Fixed unittest.mock.create_autospec() to pass the call through to the wrapped object to return the real result. - gh-115881: Fix issue where ast.parse() would incorrectly flag conditional context managers (such as with (x() if y else z()): ...) as invalid syntax if feature_version=(3, 8) was passed. This reverts changes to the grammar made as part of gh-94949. - gh-115886: Fix silent truncation of the name with an embedded null character in multiprocessing.shared_memory.SharedMemory. - gh-115532: Add kernel density estimation to the statistics module. - gh-115714: On WASI, the time module no longer get process time using times() or CLOCK_PROCESS_CPUTIME_ID, system API is that is unreliable and is likely to be removed from WASI. The affected clock functions fall back to calling clock(). - gh-115809: Improve algorithm for computing which rolled-over log files to delete in logging.TimedRotatingFileHandler. It is now reliable for handlers without namer and with arbitrary deterministic namer that leaves the datetime part in the file name unmodified. - gh-74668: urllib.parse functions parse_qs() and parse_qsl() now support bytes arguments containing raw and percent-encoded non-ASCII data. - gh-67044: csv.writer() now always quotes or escapes '\r' and '\n', regardless of lineterminator value. - gh-115712: Restore support of space delimiter with skipinitialspace=True in csv. csv.writer() now quotes empty fields if delimiter is a space and skipinitialspace is true and raises exception if quoting is not possible. - gh-112364: Fixed ast.unparse() to handle format_spec with ", ' or \\. Patched by Frank Hoffmann. - gh-112997: Stop logging potentially sensitive callback arguments in asyncio unless debug mode is active. - gh-114914: Fix an issue where an abandoned StreamWriter would not be garbage collected. - gh-111358: Fix a bug in asyncio.BaseEventLoop.shutdown_default_executor() to ensure the timeout passed to the coroutine behaves as expected. - gh-115618: Fix improper decreasing the reference count for None argument in property methods getter(), setter() and deleter(). - gh-112720: Refactor dis.ArgResolver to make it possible to subclass and change the way jump args are interpreted. - gh-112006: Fix inspect.unwrap() for types with the __wrapper__ data descriptor. Fix inspect.Signature.from_callable() for builtins classmethod() and staticmethod(). - gh-101293: Support callables with the __call__() method and types with __new__() and __init__() methods set to class methods, static methods, bound methods, partial functions, and other types of methods and descriptors in inspect.Signature.from_callable(). - gh-103092: Isolate _lsprof (apply PEP 687). - gh-113942: pydoc no longer skips global functions implemented as builtin methods, such as MethodDescriptorType and WrapperDescriptorType. - gh-115256: Added DeprecationWarning when accessing the tarfile attribute of TarInfo objects. The attribute is never used internally and is only attached to TarInfos when the tarfile is opened in write-mode, not read-mode. The attribute creates an unnecessary reference cycle which may cause corruption when not closing the handle after writing a tarfile. - gh-115197: urllib.request no longer resolves the hostname before checking it against the system’s proxy bypass list on macOS and Windows. - gh-113812: DatagramTransport.sendto() will now send zero-length datagrams if called with an empty bytes object. The transport flow control also now accounts for the datagram header when calculating the buffer size. - gh-114763: Protect modules loaded with importlib.util.LazyLoader from race conditions when multiple threads try to access attributes before the loading is complete. - gh-114709: posixpath.commonpath() now raises a ValueError exception when passed an empty iterable.

Patch contributed by Rémi Lapeyre. - bpo-33775: Add ‘default’ and ‘version’ help text for localization in argparse. - Documentation - gh-115399: Document CVE-2023-52425 of Expat <2.6.0 under “XML vulnerabilities”. - gh-109653: Improve import time of uuid on Linux. - Tests - gh-71052: Add test exclusions to support running the test suite on Android. - gh-71052: Enable test_concurrent_futures on platforms that support threading but not multiprocessing. - gh-115796: Make ‘_testinternalcapi.assemble_code_object’ construct the exception table for the code object. - gh-115720: Leak tests (-R, --huntrleaks) now show a summary of the number of leaks found in each iteration. - gh-115122: Add --bisect option to regrtest test runner: run failed tests with test.bisect_cmd to identify failing tests. Patch by Victor Stinner. - gh-115596: Fix ProgramPriorityTests in test_os permanently changing the process priority. - gh-115556: On Windows, commas passed in arguments to Tools\buildbot\test.bat and PCbuild\\rt.bat are now properly handled. - gh-115420: Fix translation of exception hander targets by _testinternalcapi.optimize_cfg. - gh-115376: Fix segfault in _testinternalcapi.compiler_codegen on bad input. ------------------------------------------------------------------- Thu Mar 7 08:16:28 UTC 2024 - Daniel Garcia - Drop gh115133-XMLPullParserTest-fail.patch upstreamed now. ------------------------------------------------------------------- Wed Mar 6 14:13:58 UTC 2024 - Pedro Monreal - Use the system-wide crypto-policies [bsc#1211301] * Use the system default cipher list instead of hardcoded values * Add the --with-ssl-default-suites=openssl configure option ------------------------------------------------------------------- Tue Mar 5 10:32:33 UTC 2024 - Daniel Garcia - Update to 3.13.0a4 - Security - gh-115399: Update bundled libexpat to 2.6.0 - gh-115243: Fix possible crashes in collections.deque.index() when the deque is concurrently modified. - Core and Builtins - gh-112087: For an empty reverse iterator for list will be reduced to reversed(). Patch by Donghee Na - gh-114570: Add PythonFinalizationError exception. This exception derived from RuntimeError is raised when an operation is blocked during the Python finalization. Patch by Victor Stinner. - gh-114695: Add sys._clear_internal_caches(), which clears all internal performance-related caches (and deprecate the less-general sys._clear_type_cache() function). - gh-114828: Fix compilation crashes in uncommon code examples using super() inside a comprehension in a class body. - gh-112069: Adapt set and frozenset methods to Argument Clinic. - gh-115011: Setters for members with an unsigned integer type now support the same range of valid values for objects that has a __index__() method as for int. - gh-114887: Changed socket type validation in create_datagram_endpoint() to accept all non-stream sockets. This fixes a regression in compatibility with raw sockets. - gh-114944: Fixes a race between PyParkingLot_Park and _PyParkingLot_UnparkAll. - gh-113462: Limit the number of versions that a single class can use. Prevents a few wayward classes using up all the version numbers. - gh-76763: The chr() builtin function now always raises ValueError for values outside the valid range. Previously it raised OverflowError for very large or small values. - gh-114806: No longer specialize calls to classes, if those classes have metaclasses. Fixes bug where the __call__ method of the metaclass was not being called. - gh-107944: Improve error message for function calls with bad keyword arguments via getargs - gh-112529: The free-threaded build no longer allocates space for the PyGC_Head structure in objects that support cyclic garbage collection. A number of other fields and data structures are used as replacements, including ob_gc_bits, ob_tid, and mimalloc internal data structures. - gh-114456: Lower the recursion limit under a debug build of WASI. - gh-114083: Compiler applies folding of LOAD_CONST with following instruction in a separate pass before other optimisations. This enables jump threading in certain circumstances. - gh-114388: Fix a RuntimeWarning emitted when assign an integer-like value that is not an instance of int to an attribute that corresponds to a C struct member of type T_UINT and T_ULONG. Fix a double RuntimeWarning emitted when assign a negative integer value to an attribute that corresponds to a C struct member of type T_UINT. - gh-114265: Compiler propagates line numbers before optimization, leading to more optimization opportunities and removing the need for the guarantee_lineno_for_exits hack. - gh-112529: The free-threaded build now has its own thread-safe GC implementation that uses mimalloc to find GC tracked objects. It is non-generational, unlike the existing GC implementation. - gh-114050: Fix segmentation fault caused by an incorrect format string in TypeError exception when more than two arguments are passed to int. - gh-112354: The END_FOR instruction now pops only one value. This is to better support side exits in loops. - gh-113884: Make queue.SimpleQueue thread safe when the GIL is disabled. - gh-114058: Implement the foundations of the Tier 2 redundancy eliminator. - gh-113939: frame.clear(): Clear frame.f_locals as well, and not only the fast locals. This is relevant once frame.f_locals was accessed, which would contain also references to all the locals. - gh-112050: Convert collections.deque to use Argument Clinic. - gh-112050: Make methods on collections.deque thread-safe when the GIL is disabled. - gh-113464: Add an option (--enable-experimental-jit for configure-based builds or --experimental-jit for PCbuild-based ones) to build an experimental just-in-time compiler, based on copy-and-patch - gh-113055: Make interp->obmalloc a pointer. For interpreters that share state with the main interpreter, this points to the same static memory structure. For interpreters with their own obmalloc state, it is heap allocated. Add free_obmalloc_arenas() which will free the obmalloc arenas and radix tree structures for interpreters with their own obmalloc state. - gh-55664: Add warning when creating type using a namespace dictionary with non-string keys. Patched by Daniel Urban and Furkan Onder. - gh-104530: Use native Win32 condition variables. - Library - gh-115392: Fix a bug in doctest where incorrect line numbers would be reported for decorated functions. - gh-114563: Fix several format() bugs when using the C implementation of Decimal: * memory leak in some rare cases when using the z format option (coerce negative 0) * incorrect output when applying the z format option to type F (fixed-point with capital NAN / INF) * incorrect output when applying the # format option (alternate form) - gh-102840: Fix confused traceback when floordiv, mod, or divmod operations happens between instances of fractions.Fraction and complex. - gh-115165: Most exceptions are now ignored when attempting to set the __orig_class__ attribute on objects returned when calling typing generic aliases (including generic aliases created using typing.Annotated). Previously only AttributeError was ignored. Patch by Dave Shawley. - gh-112903: Fix “issubclass() arg 1 must be a class” errors in certain cases of multiple inheritance with generic aliases (regression in early 3.13 alpha releases). - gh-115133: Fix tests for XMLPullParser with Expat 2.6.0. - gh-115059: io.BufferedRandom.read1() now flushes the underlying write buffer. - gh-79382: Trailing ** no longer allows to match files and non-existing paths in recursive glob(). - gh-67837: Avoid race conditions in the creation of directories during concurrent extraction in tarfile and zipfile. - gh-115060: Speed up pathlib.Path.glob() by removing redundant regex matching. - gh-97928: Partially revert the behavior of tkinter.Text.count(). By default it preserves the behavior of older Python versions, except that setting wantobjects to 0 no longer has effect. Add a new parameter return_ints: specifying return_ints=True makes Text.count() always returning the single count as an integer instead of a 1-tuple or None. - gh-114628: When csv.Error is raised when handling TypeError, do not print the TypeError traceback. - gh-85984: Added _POSIX_VDISABLE from C’s to termios. - gh-114965: Update bundled pip to 24.0 - gh-114959: tarfile no longer ignores errors when trying to extract a directory on top of a file. - gh-114894: Add array.array.clear(). - gh-114071: Support tuple subclasses using auto() for enum member value. - gh-109475: Fix support of explicit option value “–” in argparse (e.g. --option=--). - gh-49766: Fix date-datetime comparison. Now the special comparison methods like __eq__ and __lt__ return NotImplemented if one of comparands is date and other is datetime instead of ignoring the time part and the time zone or forcefully return “not equal” or raise TypeError. It makes comparison of date and datetime subclasses more symmetric and allows to change the default behavior by overriding the special comparison methods in subclasses. - gh-110190: Fix ctypes structs with array on Windows ARM64 platform by setting MAX_STRUCT_SIZE to 32 in stgdict. Patch by Diego Russo - gh-114678: Ensure that deprecation warning for ‘N’ specifier in Decimal format is not raised for cases where ‘N’ appears in other places in the format specifier. Based on patch by Stefan Krah. - gh-70303: Return both files and directories from pathlib.Path.glob() if a pattern ends with “**”. Previously only directories were returned. - gh-109653: Improve import time of importlib.metadata and email.utils. - gh-113280: Fix a leak of open socket in rare cases when error occurred in ssl.SSLSocket creation. - gh-77749: email.policy.EmailPolicy.fold() now always encodes non-ASCII characters in headers if utf8 is false. - gh-83383: Synchronization of the dbm.dumb database is now no-op if there was no modification since opening or last synchronization. The directory file for a newly created empty dbm.dumb database is now created immediately after opening instead of deferring this until synchronizing or closing. - gh-91602: Add filter keyword-only parameter to sqlite3.Connection.iterdump() for filtering database objects to dump. Patch by Mariusz Felisiak. - gh-112451: Prohibit subclassing pure-Python datetime.timezone. This is consistent with C-extension implementation. Patch by Mariusz Felisiak. - gh-69893: Add the close() method for the iterator returned by xml.etree.ElementTree.iterparse(). - gh-109653: Reduce the import time of threading module by ~50%.

Previously it could leave a random garbage in some fields. - gh-114315: Make threading.Lock a real class, not a factory function. Add __new__ to _thread.lock type. - gh-100414: Add dbm.sqlite3 as a backend to dbm, and make it the new default dbm backend. Patch by Raymond Hettinger and Erlend E. Aasland. - gh-113267: Revert changes in gh-106584 which made calls of TestResult methods startTest() and stopTest() unbalanced. - gh-75128: Ignore an OSError in asyncio.BaseEventLoop.create_server() when IPv6 is available but the interface cannot actually support it. - gh-114423: _DummyThread entries in threading._active are now automatically removed when the related thread dies. - gh-114257: Dismiss the FileNotFound error in ctypes.util.find_library() and just return None on Linux. - gh-114321: Expose more platform specific constants in the fcntl module on Linux, macOS, FreeBSD and NetBSD. - gh-114328: The tty.setcbreak() and new tty.cfmakecbreak() no longer clears the terminal input ICRLF flag. This fixes a regression introduced in 3.12 that no longer matched how OSes define cbreak mode in their stty(1) manual pages. - gh-114281: Remove type hints from Lib/asyncio/staggered.py. The annotations in the typeshed project should be used instead. - gh-101438: Avoid reference cycle in ElementTree.iterparse. The iterator returned by ElementTree.iterparse may hold on to a file descriptor. The reference cycle prevented prompt clean-up of the file descriptor if the returned iterator was not exhausted. - gh-114198: The signature for the __replace__ method on dataclasses now has the first argument named self, rather than obj. - gh-104522: OSError raised when run a subprocess now only has filename attribute set to cwd if the error was caused by a failed attempt to change the current directory. - gh-114149: Enum: correctly handle tuple subclasses in custom __new__. - gh-83648: Support deprecation of options, positional arguments and subcommands in argparse. - gh-114087: Speed up dataclasses.asdict up to 1.35x. - gh-109534: Fix a reference leak in asyncio.selector_events.BaseSelectorEventLoop when SSL handshakes fail. Patch contributed by Jamie Phan. - gh-79634: Accept path-like objects as patterns in pathlib.Path.glob() and rglob(). - gh-112202: Ensure that a asyncio.Condition.notify() call does not get lost if the awakened Task is simultaneously cancelled or encounters any other error. - gh-113951: Fix the behavior of tag_unbind() methods of tkinter.Text and tkinter.Canvas classes with three arguments. Previously, widget.tag_unbind(tag, sequence, funcid) destroyed the current binding for sequence, leaving sequence unbound, and deleted the funcid command. Now it removes only funcid from the binding for sequence, keeping other commands, and deletes the funcid command. It leaves sequence unbound only if funcid was the last bound command. - gh-97959: Fix rendering class methods, bound methods, method and function aliases in pydoc. Class methods no longer have “method of builtins.type instance” note. Corresponding notes are now added for class and unbound methods. Method and function aliases now have references to the module or the class where the origin was defined if it differs from the current. Bound methods are now listed in the static methods section. Methods of builtin classes are now supported as well as methods of Python classes. - gh-113796: Add more validation checks in the csv.Dialect constructor. ValueError is now raised if the same character is used in different roles. - gh-113732: Fix support of QUOTE_NOTNULL and QUOTE_STRINGS in csv.reader(). - gh-113225: Speed up pathlib.Path.walk() by using os.DirEntry.path where possible. - gh-89039: When replace() method is called on a subclass of datetime, date or time, properly call derived constructor. Previously, only the base class’s constructor was called. - Also, make sure to pass non-zero fold values when creating subclasses in various methods. Previously, fold was silently ignored. - gh-112919: Speed-up datetime.datetime.replace(), datetime.date.replace() and datetime.time.replace(). - gh-59013: Set breakpoint on the first executable line of the function, instead of the line of function definition when the user do break func using pdb - gh-112343: Improve handling of pdb convenience variables to avoid replacing string contents. - gh-112240: Add option to calendar module CLI to specify the weekday to start each week. Patch by Steven Ward. - gh-111741: Recognise image/webp as a standard format in the mimetypes module. - gh-43457: Fix the tkinter widget method wm_attributes(). It now accepts the attribute name without the minus prefix to get window attributes and allows to specify attributes and values to set as keyword arguments. Add new optional keyword argument return_python_dict: calling w.wm_attributes(return_python_dict=True) returns the attributes as a dict instead of a tuple. Calling w.wm_attributes() now returns a tuple instead of string if wantobjects was set to 0. - gh-82626: Many functions now emit a warning if a boolean value is passed as a file descriptor argument. - gh-111051: Added check for file modification during debugging with pdb - gh-110345: Show the Tcl/Tk patchlevel (rather than version) in tkinter._test(). - gh-38807: Fix race condition in trace. Instead of checking if a directory exists and creating it, directly call os.makedirs() with the kwarg exist_ok=True. - gh-75705: Set unixfrom envelope in mailbox.mbox and mailbox.MMDF. - gh-106233: Fix stacklevel in InvalidTZPathWarning during zoneinfo module import. - gh-105102: Allow ctypes.Union to be nested in ctypes.Structure when the system endianness is the opposite of the classes. - gh-104282: Fix null pointer dereference in lzma._decode_filter_properties() due to improper handling of BCJ filters with properties of zero length. Patch by Radislav Chugunov. - gh-96471: Add queue.Queue termination with shutdown(). - gh-101599: Changed argparse flag options formatting to remove redundancy. - gh-85984: Add POSIX pseudo-terminal functions os.posix_openpt(), os.grantpt(), os.unlockpt(), and os.ptsname(). - gh-102512: When os.fork() is called from a foreign thread (aka _DummyThread), the type of the thread in a child process is changed to _MainThread. Also changed its name and daemonic status, it can be now joined. - gh-88569: Add os.path.isreserved(), which identifies reserved pathnames such as “NUL”, “AUX” and “CON”. This function is only available on Windows. - Deprecate pathlib.PurePath.is_reserved(). - bpo-38364: The inspect functions isgeneratorfunction, iscoroutinefunction, isasyncgenfunction now support functools.partialmethod wrapped functions the same way they support functools.partial. - Documentation - gh-115233: Fix an example for LoggerAdapter in the Logging Cookbook. - gh-114123: Move the csv module docstring to the csv module instead of reexporting it from the internal _csv module, and remove __doc__ from csv.__all__. - Move csv.__version__ to the csv module instead of reexporting it from the internal _csv module, and remove __version__ from csv.__all__. Test- s - gh-114099: Added test exclusions required to run the test suite on iOS. - gh-105089: Fix test.test_zipfile.test_core.TestWithDirectory.test_create_directory_with_write test in AIX by doing a bitwise AND of 0xFFFF on mode , so that it will be in sync with zinfo.external_attr Buil- d - gh-115167: Avoid vendoring vcruntime140_threads.dll when building with Visual Studio 2022 version 17.8. - gh-113632: Promote WASI to a tier 2 platform and drop Emscripten from tier 3 in configure.ac. - gh-114099: configure and Makefile were refactored to accomodate framework builds on Apple platforms other than macOS. - gh-114875: Add getgrent() as a prerequisite for building the grp module.

Only the positional parameter count was checked; any keyword argument passed would be silently accepted. - C API - gh-111140: Adds PyLong_AsNativeBytes(), PyLong_FromNativeBytes() and PyLong_FromUnsignedNativeBytes() functions. - gh-114685: PyBuffer_FillInfo() now raises a SystemError if called with PyBUF_READ or PyBUF_WRITE as flags. These flags should only be used with the PyMemoryView_* C API. - gh-114685: PyObject_GetBuffer() now raises a SystemError if called with PyBUF_READ or PyBUF_WRITE as flags. These flags should only be used with the PyMemoryView_* C API. - gh-114626: Add PyCFunctionFast and PyCFunctionFastWithKeywords typedefs (identical to the existing _PyCFunctionFast and _PyCFunctionFastWithKeywords typedefs, just without a leading _ prefix). - gh-114329: Add PyList_GetItemRef(), which is similar to PyList_GetItem() but returns a strong reference instead of a borrowed reference. - gh-110850: Add PyTime C API: * PyTime_t type. * PyTime_MIN and PyTime_MAX constants. * PyTime_AsSecondsDouble(), PyTime_Monotonic(), PyTime_PerfCounter(), and PyTime_Time() functions. - gh-112066: Add PyDict_SetDefaultRef(): insert a key and value into a dictionary if the key is not already present. This is similar to dict.setdefault(), but returns an integer value indicating if the key was already present. It is also similar to PyDict_SetDefault(), but returns a strong reference instead of a borrowed reference. ------------------------------------------------------------------- Tue Feb 20 18:12:05 UTC 2024 - Matej Cepl - Add gh115133-XMLPullParserTest-fail.patch to make Python building with the current libexpat 2.6.0 (gh#python/cpython#115133). - Switch to %%autopatch. Let’s try it as an experiment, and if we need conditional patch, we should put condition inside of it. - Remove double definition of /usr/bin/idle%%{version} in %%files. ------------------------------------------------------------------- Thu Feb 8 08:10:09 UTC 2024 - Daniel Garcia - Update to 3.13.0a3 - Security - gh-113659: Skip .pth files with names starting with a dot or hidden file attribute. - gh-112302: Created a Software Bill-of-Materials document and tooling for tracking dependencies. - Core and Builtins - gh-107901: Compiler duplicates basic blocks that have an eval breaker check, no line number, and multiple predecessors. - gh-107901: A jump leaving an exception handler back to normal code no longer checks the eval breaker. - gh-113655: Set the C recursion limit to 4000 on Windows, and 10000 on Linux/OSX. This seems to be near the sweet spot to maintain safety, but not compromise backwards compatibility. - gh-113710: Add typed stack effects to the interpreter DSL, along with various instruction annotations. - gh-77046: On Windows, file descriptors wrapping Windows handles are now created non inheritable by default (PEP 446). Patch by Zackery Spytz and Victor Stinner. - gh-113853: Guarantee that all executors make progress. This then guarantees that tier 2 execution always makes progress. - gh-113753: Fix an issue where the finalizer of PyAsyncGenASend objects might not be called if they were allocated from a free list. - gh-107901: Compiler changed so that synthetic jumps which are not at loop end no longer check the eval breaker. - gh-113703: Fix a regression in the codeop module that was causing it to incorrectly identify incomplete f-strings. Patch by Pablo Galindo - gh-89811: Check for a valid tp_version_tag before performing bytecode specializations that rely on this value being usable. - gh-111488: Changed error message in case of no ‘in’ keyword after ‘for’ in list comprehensions - gh-113657: Fix an issue that caused important instruction pointer updates to be optimized out of tier two traces. - gh-113603: Fixed bug where a redundant NOP is not removed, causing an assertion to fail in the compiler in debug mode. - gh-113602: Fix an error that was causing the parser to try to overwrite existing errors and crashing in the process. Patch by Pablo Galindo - gh-113486: No longer issue spurious PY_UNWIND events for optimized calls to classes. - gh-113297: Fix segfault in the compiler on with statement with 19 context managers. - gh-113212: Improve super error messages. - gh-111375: Only use NULL in the exception stack to indicate an exception was handled. Patch by Carey Metcalfe. - gh-112215: Increase the C recursion limit by a factor of 3 for non-debug builds, except for webassembly and s390 platforms which are unchanged. This mitigates some regressions in 3.12 with deep recursion mixing builtin (C) and Python code. - gh-113054: Fixed bug where a redundant NOP is not removed, causing an assertion to fail in the compiler in debug mode. - gh-106905: Use per AST-parser state rather than global state to track recursion depth within the AST parser to prevent potential race condition due to simultaneous parsing. - The issue primarily showed up in 3.11 by multithreaded users of ast.parse(). In 3.12 a change to when garbage collection can be triggered prevented the race condition from occurring. - gh-108866: Change the API and contract of _PyExecutorObject to return the next_instr pointer, instead of the frame, and to always execute at least one instruction. - gh-90350: Optimize builtin functions min() and max(). - gh-112943: Correctly compute end column offsets for multiline tokens in the tokenize module. Patch by Pablo Galindo - gh-112125: Fix None.__ne__(None) returning NotImplemented instead of False - gh-74616: input() now raises a ValueError when output on the terminal if the prompt contains embedded null characters instead of silently truncating it. - gh-112716: Fix SystemError in the import statement and in __reduce__() methods of builtin types when __builtins__ is not a dict. - gh-112730: Use color to highlight error locations in tracebacks. Patch by Pablo Galindo - gh-112625: Fixes a bug where a bytearray object could be cleared while iterating over an argument in the bytearray.join() method that could result in reading memory after it was freed. - gh-112660: Do not clear unexpected errors during formatting error messages for ImportError and AttributeError for modules. - gh-105967: Workaround a bug in Apple’s macOS platform zlib library where zlib.crc32() and binascii.crc32() could produce incorrect results on multi-gigabyte inputs. Including when using zipfile on zips containing large data. - gh-95754: Provide a better error message when accessing invalid attributes on partially initialized modules. The origin of the module being accessed is now included in the message to help with the common issue of shadowing other modules. - gh-112217: Add check for the type of __cause__ returned from calling the type T in raise from T. - gh-111058: Change coro.cr_frame/gen.gi_frame to return None after the coroutine/generator has been closed. This fixes a bug where getcoroutinestate() and getgeneratorstate() return the wrong state for a closed coroutine/generator. - gh-112388: Fix an error that was causing the parser to try to overwrite tokenizer errors. Patch by pablo Galindo - gh-112387: Fix error positions for decoded strings with backwards tokenize errors.

Patch by Pablo Galindo - gh-112320: The Tier 2 translator now tracks the confidence level for staying “on trace” (i.e. not exiting back to the Tier 1 interpreter) for branch instructions based on the number of bits set in the branch “counter”. Trace translation ends when the confidence drops below 1/3rd. - gh-109598: PyComplex_RealAsDouble()/PyComplex_ImagAsDouble() now tries to convert an object to a complex instance using its __complex__() method before falling back to the __float__() method. Patch by Sergey B Kirpichev. - gh-94606: Fix UnicodeEncodeError when email.message.get_payload() reads a message with a Unicode surrogate character and the message content is not well-formed for surrogateescape encoding. Patch by Sidney Markowitz. - bpo-21861: Use the object’s actual class name in _io.FileIO.__repr__(), _io._WindowsConsoleIO() and _io.TextIOWrapper.__repr__(), to make these methods subclass friendly. - bpo-45369: Remove LibreSSL workarounds as per PEP 644. - bpo-34392: Added sys._is_interned(). Libr- ary - gh-114077: Fix possible OverflowError in socket.socket.sendfile() when pass count larger than 2 GiB on 32-bit platform. - gh-111803: plistlib now supports loading more deeply nested lists in binary format. - gh-114014: Fixed a bug in fractions.Fraction where an invalid string using d in the decimals part creates a different error compared to other invalid letters/characters. Patch by Jeremiah Gabriel Pascual. - gh-108364: sqlite3.Connection.iterdump() now ensures that foreign key support is disabled before dumping the database schema, if there is any foreign key violation. Patch by Erlend E. Aasland and Mariusz Felisiak. - gh-113971: The zipfile.ZipInfo previously protected ._compresslevel attribute has been made public as .compress_level with the old _compresslevel name remaining available as a property to retain compatibility. - gh-113877: Fix tkinter method winfo_pathname() on 64-bit Windows. - gh-113868: Added mmap.MAP_NORESERVE, mmap.MAP_NOEXTEND, mmap.MAP_HASSEMAPHORE, mmap.MAP_NOCACHE, mmap.MAP_JIT, mmap.MAP_RESILIENT_CODESIGN, mmap.MAP_RESILIENT_MEDIA, mmap.MAP_32BIT, mmap.MAP_TRANSLATED_ALLOW_EXECUTE, mmap.MAP_UNIX03 and mmap.MAP_TPRO. All of them are mmap(2) flags on macOS. - gh-113848: asyncio.TaskGroup() and asyncio.timeout() context managers now handle CancelledError subclasses as well as exact CancelledError. - gh-113661: unittest runner: Don’t exit 5 if tests were skipped. The intention of exiting 5 was to detect issues where the test suite wasn’t discovered at all. If we skipped tests, it was correctly discovered. - gh-96037: Insert TimeoutError in the context of the exception that was raised during exiting an expired asyncio.timeout() block. - gh-113781: Silence unraisable AttributeError when warnings are emitted during Python finalization. - gh-113238: Add Anchor to importlib.resources (in order for the code to comply with the documentation) - gh-111693: asyncio.Condition.wait() now re-raises the same CancelledError instance that may have caused it to be interrupted. Fixed race condition in asyncio.Semaphore.aquire() when interrupted with a CancelledError. - gh-113791: Add CLOCK_MONOTONIC_RAW_APPROX and CLOCK_UPTIME_RAW_APPROX to time on macOS. These are clocks available on macOS 10.12 or later. - gh-112932: Restore the ability for zipfile to extractall from zip files with a “/” directory entry in them as is commonly added to zips by some wiki or bug tracker data exporters. - gh-113568: Raise deprecation warnings from pathlib.PurePath and not its private base class PurePathBase. - gh-113594: Fix UnicodeEncodeError in email when re-fold lines that contain unknown-8bit encoded part followed by non-unknown-8bit encoded part. - gh-113538: In asyncio.StreamReaderProtocol.connection_made(), there is callback that logs an error if the task wrapping the “connected callback” fails. This callback would itself fail if the task was cancelled. Prevent this by checking whether the task was cancelled first. If so, close the transport but don’t log an error. - gh-113626: Add support for the allow_code argument in the marshal module. Passing allow_code=False prevents serialization and de-serialization of code objects which is incompatible between Python versions. - gh-85567: Fix resource warnings for unclosed files in pickle and pickletools command line interfaces. - gh-113537: Support loads str in plistlib.loads(). - gh-89850: Add default implementations of pickle.Pickler.persistent_id() and pickle.Unpickler.persistent_load() methods in the C implementation. Calling super().persistent_id() and super().persistent_load() in subclasses of the C implementation of pickle.Pickler and pickle.Unpickler classes no longer causes infinite recursion. - gh-113569: Indicate if there were no actual calls in unittest assert_has_calls() failure. - gh-101225: Increase the backlog for multiprocessing.connection.Listener objects created by multiprocessing.manager and multiprocessing.resource_sharer to significantly reduce the risk of getting a connection refused error when creating a multiprocessing.connection.Connection to them. - gh-113568: Raise audit events from pathlib.Path and not its private base class PathBase. - gh-113543: Make sure that webbrowser.MacOSXOSAScript sends webbrowser.open audit event. - gh-113028: When a second reference to a string appears in the input to pickle, and the Python implementation is in use, we are guaranteed that a single copy gets pickled and a single object is shared when reloaded. Previously, in protocol 0, when a string contained certain characters (e.g. newline) it resulted in duplicate objects. - gh-113421: Fix multiprocessing logger for %(filename)s. - gh-111784: Fix segfaults in the _elementtree module. Fix first segfault during deallocation of _elementtree.XMLParser instances by keeping strong reference to pyexpat module in module state for capsule lifetime. Fix second segfault which happens in the same deallocation process by keeping strong reference to _elementtree module in XMLParser structure for _elementtree module lifetime. - gh-113407: Fix import of unittest.mock when CPython is built without docstrings. - gh-113320: Fix regression in Python 3.12 where Protocol classes that were not marked as runtime-checkable would be unnecessarily introspected, potentially causing exceptions to be raised if the protocol had problematic members. Patch by Alex Waygood. - gh-53502: Add a new option aware_datetime in plistlib to loads or dumps aware datetime. - gh-113358: Fix rendering tracebacks with exceptions with a broken __getattr__ - gh-113214: Fix an AttributeError during asyncio SSL protocol aborts in SSL-over-SSL scenarios. - gh-113246: Update bundled pip to 23.3.2. - gh-87264: Fixed tarfile list() method to show file type. - gh-112182: asyncio.futures.Future.set_exception() now transforms StopIteration into RuntimeError instead of hanging or other misbehavior. Patch contributed by Jamie Phan. - gh-113225: Speed up pathlib.Path.glob() by using os.DirEntry.path where possible. - gh-113149: Improve error message when a JSON array or object contains a trailing comma. Patch by Carson Radtke. - gh-113117: The subprocess module can now use the os.posix_spawn() function with close_fds=True on platforms where posix_spawn_file_actions_addclosefrom_np is available. Patch by Jakub Kulik. - gh-113199: Make http.client.HTTPResponse.read1 and http.client.HTTPResponse.readline close IO after reading all data when content length is known. Patch by Illia Volochii. - gh-113191: Add support of os.fchmod() and a file descriptor in os.chmod() on Windows. - gh-113188: Fix shutil.copymode() and shutil.copystat() on Windows. Previously they worked differenly if dst is a symbolic link: they modified the permission bits of dst itself rather than the file it points to if follow_symlinks is true or src is not a symbolic link, and did not modify the permission bits if follow_symlinks is false and src is a symbolic link. - gh-113119: os.posix_spawn() now accepts env=None, which makes the newly spawned process use the current process environment. Patch by Jakub Kulik. - gh-113202: Add a strict option to batched() in the itertools module. - gh-61648: Detect line numbers of properties in doctests. - gh-113175: Sync with importlib_metadata 7.0, including improved type annotations, fixed issue with symlinked packages in package_distributions, added EntryPoints.__repr__, introduced the diagnose script, added Distribution.origin property, and removed deprecated EntryPoint access by numeric index (tuple behavior). - gh-59616: Add support of os.lchmod() and the follow_symlinks argument in os.chmod() on Windows. Note that the default value of follow_symlinks in os.lchmod() is False on Windows. - gh-112559: signal.signal() and signal.getsignal() no longer call repr on callable handlers. asyncio.run() and asyncio.Runner.run() no longer call repr on the task results. Patch by Yilei Yang. - gh-112962: dis module functions add cache information to the Instruction instance rather than creating fake Instruction instances to represent the cache entries. - gh-112989: Reduce overhead to connect sockets with asyncio SelectorEventLoop. - gh-112970: Use closefrom() on Linux where available (e.g. glibc-2.34), rather than only FreeBSD. - gh-110190: Fix ctypes structs with array on PPC64LE platform by setting MAX_STRUCT_SIZE to 64 in stgdict. Patch by Diego Russo. - gh-112540: The statistics.geometric_mean() function now returns zero for datasets containing a zero. Formerly, it would raise an exception. - gh-87286: Added LOG_FTP, LOG_NETINFO, LOG_REMOTEAUTH, LOG_INSTALL, LOG_RAS, and LOG_LAUNCHD tot the syslog module, all of them constants on used on macOS. - gh-112800: Fix asyncio SubprocessTransport.close() not to throw PermissionError when used with setuid executables. - gh-51944: Add the following constants to the termios module. These values are present in macOS system headers: ALTWERASE, B14400, B28800, B7200, B76800, CCAR_OFLOW, CCTS_OFLOW, CDSR_OFLOW, CDTR_IFLOW, CIGNORE, CRTS_IFLOW, EXTPROC, IUTF8, MDMBUF, NL2, NL3, NOKERNINFO, ONOEOT, OXTABS, VDSUSP, VSTATUS. - gh-79325: Fix an infinite recursion error in tempfile.TemporaryDirectory() cleanup on Windows. - gh-94692: shutil.rmtree() now only catches OSError exceptions. Previously a symlink attack resistant version of shutil.rmtree() could ignore or pass to the error handler arbitrary exception when invalid arguments were provided. - gh-112736: The use of del-safe symbols in subprocess was refactored to allow for use in cross-platform build environments. - gh-112727: Speed up pathlib.Path.absolute(). Patch by Barney Gale. - gh-74690: Speedup issubclass() checks against simple runtime-checkable protocols by around 6%. Patch by Alex Waygood. - gh-74690: Speedup isinstance() checks by roughly 20% for runtime-checkable protocols that only have one callable member. Speedup issubclass() checks for these protocols by roughly 10%. Patch by Alex Waygood. - gh-112645: Remove deprecation error on passing onerror to shutil.rmtree(). - gh-112640: Add kwdefaults parameter to types.FunctionType to set default keyword argument values. - gh-112622: Ensure name parameter is passed to event loop in asyncio.create_task(). - gh-112618: Fix a caching bug relating to typing.Annotated. Annotated[str, True] is no longer identical to Annotated[str, 1]. - gh-112334: Fixed a performance regression in 3.12’s subprocess on Linux where it would no longer use the fast-path vfork() system call when it could have due to a logic bug, instead falling back to the safe but slower fork(). - Also fixed a second 3.12.0 potential security bug. If a value of extra_groups=[] was passed to subprocess.Popen or related APIs, the underlying setgroups(0, NULL) system call to clear the groups list would not be made in the child process prior to exec(). - This was identified via code inspection in the process of fixing the first bug. - gh-110190: Fix ctypes structs with array on Arm platform by setting MAX_STRUCT_SIZE to 32 in stgdict. Patch by Diego Russo. - gh-81194: Fix a crash in socket.if_indextoname() with specific value (UINT_MAX).

Patch by Jelle Zijlstra. - gh-101336: Add keep_alive keyword parameter for AbstractEventLoop.create_server() and BaseEventLoop.create_server(). - gh-63284: Added support for TLS-PSK (pre-shared key) mode to the ssl module. - gh-112414: Fix regression in Python 3.12 where calling repr() on a module that had been imported using a custom loader could fail with AttributeError. Patch by Alex Waygood. - gh-112358: Revert change to struct.Struct initialization that broke some cases of subclassing. - gh-112405: Optimize pathlib.PurePath.relative_to(). Patch by Alex Waygood. - gh-94722: Fix bug where comparison between instances of DocTest fails if one of them has None as its lineno. - gh-112361: Speed up a small handful of pathlib methods by removing some temporary objects. - gh-112345: Improve error message when trying to call issubclass() against a typing.Protocol that has non-method members. Patch by Randolf Scholz. - gh-112137: Change dis output to display no-lineno as “–” instead of “None”. - gh-112332: Deprecate the exc_type field of traceback.TracebackException.

And use it in pydoc to render more readable signatures that have new lines between parameters. - gh-112105: Make readline.set_completer_delims() work with libedit - gh-106922: Display multiple lines with traceback when errors span multiple lines. - gh-111874: When creating a typing.NamedTuple class, ensure __set_name__() is called on all objects that define __set_name__ and exist in the values of the NamedTuple class’s class dictionary. Patch by Alex Waygood. - gh-68166: Add support of the “vsapi” element type in tkinter.ttk.Style.element_create(). - gh-110275: Named tuple’s methods _replace() and __replace__() now raise TypeError instead of ValueError for invalid keyword arguments. - gh-99367: Do not mangle sys.path[0] in pdb if safe_path is set - gh-111615: Fix a regression caused by a fix to gh-93162 whereby you couldn’t configure a QueueHandler without specifying handlers. - gh-75666: Fix the behavior of tkinter widget’s unbind() method with two arguments. Previously, widget.unbind(sequence, funcid) destroyed the current binding for sequence, leaving sequence unbound, and deleted the funcid command. Now it removes only funcid from the binding for sequence, keeping other commands, and deletes the funcid command. It leaves sequence unbound only if funcid was the last bound command. - gh-67790: Implement basic formatting support (minimum width, alignment, fill) for fractions.Fraction. - gh-111049: Fix crash during garbage collection of the io.BytesIO buffer object. - gh-102980: Redirect the output of interact command of pdb to the same channel as the debugger. Add tests and improve docs. - gh-102988: email.utils.getaddresses() and email.utils.parseaddr() now return ('', '') 2-tuples in more situations where invalid email addresses are encountered instead of potentially inaccurate values. Add optional strict parameter to these two functions: use strict=False to get the old behavior, accept malformed inputs. getattr(email.utils, 'supports_strict_parsing', False) can be use to check if the strict paramater is available. Patch by Thomas Dwyer and Victor Stinner to improve the CVE-2023-27043 fix (bsc#1210638). - gh-52161: cmd.Cmd.do_help() now cleans docstrings with inspect.cleandoc() before writing them. Patch by Filip Łapkiewicz. - gh-82300: Add track parameter to multiprocessing.shared_memory.SharedMemory that allows using shared memory blocks without having to register with the POSIX resource tracker that automatically releases them upon process exit. - gh-110109: Add private pathlib._PurePathBase class: a base class for pathlib.PurePath that omits certain magic methods. It may be made public (along with _PathBase) in future. - gh-109858: Protect zipfile from “quoted-overlap” zipbomb. It now raises BadZipFile when try to read an entry that overlaps with other entry or central directory. - gh-109786: Fix possible reference leaks and crash when re-enter the __next__() method of itertools.pairwise. - gh-91539: Small (10 - 20%) and trivial performance improvement of urrlib.request.getproxies_environment(), typically useful when there are many environment variables to go over. - gh-103363: Add follow_symlinks keyword-only argument to pathlib.Path.owner() and group(), defaulting to True. - gh-102130: Support tab completion in cmd for editline. - gh-99437: runpy.run_path() now decodes path-like objects, making sure __file__ and sys.argv[0] of the module being run are always strings. - gh-104003: Add warnings.deprecated(), a decorator to mark deprecated functions to static type checkers and to warn on usage of deprecated classes and functions. See PEP 702. Patch by Jelle Zijlstra. - gh-103708: Make hardcoded python name, a configurable parameter so that different implementations of python can override it instead of making huge diffs in sysconfig.py - gh-66515: mailbox.MH now supports folders that do not contain a .mh_sequences file (e.g. Claws Mail IMAP-cache folders). Patch by Serhiy Storchaka. - gh-83162: Renamed re.error to PatternError for clarity, and kept re.error for backward compatibility. Patch by Matthias Bussonnier and Adam Chhina. - gh-91133: Fix a bug in tempfile.TemporaryDirectory cleanup, which now no longer dereferences symlinks when working around file system permission errors. - bpo-43153: On Windows, tempfile.TemporaryDirectory previously masked a PermissionError with NotADirectoryError during directory cleanup. It now correctly raises PermissionError if errors are not ignored. Patch by Andrei Kulakov and Ken Jin. - bpo-32731: getpass.getuser() now raises OSError for all failures rather than ImportError on systems lacking the pwd module or KeyError if the password database is empty. - bpo-34321: mmap.mmap now has a trackfd parameter on Unix; if it is False, the file descriptor specified by fileno will not be duplicated. - bpo-35332: The shutil.rmtree() function now ignores errors when calling os.close() when ignore_errors is True, and os.close() no longer retried after error. - bpo-35928: io.TextIOWrapper now correctly handles the decoding buffer after read() and write(). - bpo-26791: shutil.move() now moves a symlink into a directory when that directory is the target of the symlink. This provides the same behavior as the mv shell command. The previous behavior raised an exception. Patch by Jeffrey Kintscher. - bpo-41422: Fixed memory leaks of pickle.Pickler and pickle.Unpickler involving cyclic references via the internal memo mapping. - bpo-19821: The pydoc.ispackage() function has been deprecated. - bpo-40262: The ssl.SSLSocket.recv_into() method no longer requires the buffer argument to implement __len__ and supports buffers with arbitrary item size. - bpo-39912: warnings.filterwarnings() and warnings.simplefilter() now raise appropriate exceptions instead of AssertionError. Patch contributed by Rémi Lapeyre. - bpo-37260: Fixed a race condition in shutil.rmtree() in which directory entries removed by another process or thread while shutil.rmtree() is running can cause it to raise FileNotFoundError. Patch by Jeffrey Kintscher. - bpo-36959: Fix some error messages for invalid ISO format string combinations in strptime() that referred to directives not contained in the format string. Patch by Gordon P. Hemsley. - bpo-18060: Fixed a class inheritance issue that can cause segfaults when deriving two or more levels of subclasses from a base class of Structure or Union. - bpo-29779: Add a new PYTHON_HISTORY environment variable to set the location of a .python_history file. - bpo-21360: mailbox.Maildir now ignores files with a leading dot. - Documentation - gh-111699: Relocate smtpd deprecation notice to its own section rather than under locale in What’s New in Python 3.12 document - gh-110746: Improved markup for valid options/values for methods ttk.treeview.column and ttk.treeview.heading, and for Layouts. - gh-95649: Document that the asyncio module contains code taken from v0.16.0 of the uvloop project, as well as the required MIT licensing information. - Tests - gh-111798: Disable test_super_deep() from test_call under pydebug builds on WASI; the stack depth is too small to make the test useful. - gh-111801: Lower the recursion limit in test_isinstance for test_infinitely_many_bases(). This prevents a stack overflow on a pydebug build of WASI. - gh-111802: Specify a low recursion depth for test_bad_getattr() in test.pickletester to avoid exhausting the stack under a pydebug build for WASI. - gh-44626: Fix os.path.isabs() incorrectly returning True when given a path that starts with exactly one (back)slash on Windows. - Fix pathlib.PureWindowsPath.is_absolute() incorrectly returning False for some paths beginning with two (back)slashes. - gh-113633: Use module state for the _testcapi extension module. - gh-109980: Fix test_tarfile_vs_tar in test_shutil for macOS, where system tar can include more information in the archive than shutil.make_archive. - gh-112769: The tests now correctly compare zlib version when zlib.ZLIB_RUNTIME_VERSION contains non-integer suffixes. For example zlib-ng defines the version as 1.3.0.zlib-ng. - gh-112334: Adds a regression test to verify that vfork() is used when expected by subprocess on vfork enabled POSIX systems (Linux). - gh-108927: Fixed order dependence in running tests in the same process when a test that has submodules (e.g. test_importlib) follows a test that imports its submodule (e.g. test_importlib.util) and precedes a test (e.g. test_unittest or test_compileall) that uses that submodule. - bpo-40648: Test modes that file can get with chmod() on Windows. - Build - gh-114013: Fix Tools/wasm/wasi.py to not include the path to python.wasm as part of HOSTRUNNER. The environment variable is meant to specify how to run the WASI host only, having python.wasm and relevant flags appended to the HOSTRUNNER. This fixes make test work. - gh-113258: Changed the Windows build to write out generated frozen modules into the build tree instead of the source tree. - gh-112305: Fixed the check-clean-src step performed on out of tree builds to detect errant $(srcdir)/Python/frozen_modules/*.h files and recommend appropriate source tree cleanup steps to get a working build again. - gh-112536: Add support for thread sanitizer (TSAN) - gh-112867: Fix the build for the case that WITH_PYMALLOC_RADIX_TREE=0 set. - gh-103065: Introduce Tools/wasm/wasi.py to simplify doing a WASI build. - bpo-11102: The os.major(), os.makedev(), and os.minor() functions are now available on HP-UX v3. - bpo-36351: Do not set ipv6type when cross-compiling. - IDLE - gh-72284: Improve the lists of features, editor key bindings, and shell key bingings in the IDLE doc. - gh-113903: Fix rare failure of test.test_idle, in test_configdialog. - gh-113729: Fix the “Help -> IDLE Doc” menu bug in 3.11.7 and 3.12.1. - gh-113269: Fix test_editor hang on macOS Catalina. - gh-112898: Fix processing unsaved files when quitting IDLE on macOS. - bpo-13586: Enter the selected text when opening the “Replace” dialog. - C API - gh-106560: Fix redundant declarations in the public C API. Declare PyBool_Type, PyLong_Type and PySys_Audit() only once. Patch by Victor Stinner. - gh-112438: Fix support of format units “es”, “et”, “es#”, and “et#” in nested tuples in PyArg_ParseTuple()-like functions. - gh-111545: Add Py_HashPointer() function to hash a pointer. Patch by Victor Stinner. - gh-65210: Change the declaration of the keywords parameter of PyArg_ParseTupleAndKeywords() and PyArg_VaParseTupleAndKeywords() for better compatibility with C++. - Refresh all patches - F00251-change-user-install-location.patch - bpo-31046_ensurepip_honours_prefix.patch - fix_configure_rst.patch - no-skipif-doctests.patch - python-3.3.0b1-fix_date_time_compiler.patch - python-3.3.0b1-localpath.patch - python-3.3.0b1-test-posix_fadvise.patch - skip-test_pyobject_freed_is_freed.patch - subprocess-raise-timeout.patch ------------------------------------------------------------------- Sat Nov 25 16:10:53 UTC 2023 - Matej Cepl - Update to 3.13.0a2: Python 3.13.0 alpha 2¶ - Core and Builtins: - Don’t include comments in f-string debug expressions. Patch by Pablo Galindo - Slightly optimize the Tier 2 (uop) interpreter by only loading oparg and operand when needed. Also double the trace size limit again, to 512 this time. - Change docstrings of __dict__ and __weakref__. - Lower the max parser stack depth to 1000 under WASI debug builds. - When Python is built in debug mode, set the C recursion limit to 500 instead of 1500. A debug build is likely built with low optimization level which implies higher stack memory usage than a release build. Patch by Victor Stinner. - Enable translating unspecialized FOR_ITER to Tier 2. - Make hashlib related modules thread-safe without the GIL - Deprecate assignment to a function’s __code__ field when the new code object is of a mismatched type (e.g., from a generator to a plain function). - Raise exception if frame.clear() is called on a suspended frame. - Implement native thread ids for GNU KFreeBSD. - Use exponential backoff to reduce the number of failed tier 2 optimization attempts by over 99%. - Joining a thread now ensures the underlying OS thread has exited. This is required for safer fork() in multi-threaded processes. - Make sure that tier 2 traces are de-optimized if the code is instrumented - Specialize slot loads and stores for _Py_T_OBJECT as well as Py_T_OBJECT_EX - Speed up BaseExceptionGroup.derive(), BaseExceptionGroup.subgroup(), and BaseExceptionGroup.split() by changing how they parse passed arguments. - Fix runtime crash when some error happens in opcode LOAD_FROM_DICT_OR_DEREF. - Add support for sharing tuples between interpreters using the cross-interpreter API. Patch by Anthony Shaw. - The oparg of YIELD_VALUE is now 1 if the instruction is part of a yield-from or await, and 0 otherwise. The SUSPENDED frame state is now split into SUSPENDED and SUSPENDED_YIELD_FROM. This simplifies the code in _PyGen_yf. - Merge the Tier 1 (bytecode) and Tier 2 (micro-ops) interpreters together, moving the Tier 2 interpreter loop and switch into _PyEval_EvalFrameDefault() in Python/ceval.c. The Python/executor.c file is gone. Also the TIER_ONE and TIER_TWO macros are now handled by the code generator. Beware! This changes the environment variables to enable micro-ops and their debugging to PYTHON_UOPS and PYTHON_LLTRACE. - Speed up Traceback object creation by lazily compute the line number. Patch by Pablo Galindo - Allow type comments in parenthesized with statements - Add support for sharing floats between interpreters using the cross-interpreter API. Patch by Anthony Shaw. - Add support for sharing of True and False between interpreters using the cross-interpreter API. Patch by Anthony Shaw. - Fix a bug where iso2022_jp_3 and iso2022_jp_2004 codecs read out of bounds - Fix an issue in the codeop that was causing SyntaxError exceptions raised in the presence of invalid syntax to not contain precise error messages. Patch by Pablo Galindo - Fix a bug that was causing SyntaxWarning to appear twice when parsing if invalid syntax is encountered later. Patch by Pablo galindo - Added a new environment variable PYTHON_FROZEN_MODULES. It determines whether or not frozen modules are ignored by the import machinery, equivalent of the -X frozen_modules command-line option. - Remove oparg from YIELD_VALUE. Change oparg of RESUME to include information about the except-depth. These changes make it possible to simplify the code in generator close. - Fix a regression that prevented jumping across is None and is not None when debugging. Patch by Savannah Ostrowski. - Show source lines in tracebacks when using the -c option when running Python. Patch by Pablo Galindo - Fix a bug where a global declaration in an except block is rejected when the global is used in the else block. - Fix error messages for indented blocks with functions and classes with generic type parameters. Patch by Pablo Galindo - Remove unnecessary instruction pointer updates before returning from frames. - Correctly display the traceback for MemoryError exceptions using the traceback module. Patch by Pablo Galindo - Fixed crash due to improperly initialized static MemoryError in subinterpreter. - Return NULL for PyTrace_RETURN events caused by an exception - Fix argument parsing by _PyArg_UnpackKeywordsWithVararg for functions defining pos-or-keyword, vararg, and kw-only parameters. - Replace prev_instr on the interpreter frame by instr_ptr which points to the beginning of the instruction that is currently executing (or will execute once the frame resumes). - Allow the repl to show source code and complete tracebacks. Patch by Pablo Galindo - Add PYTHON_PRESITE=package.module to import a module early in the interpreter lifecycle before site.py is executed. Python needs to be built in debug mode for this option to exist. - Implement biased reference counting in --disable-gil builds. - Fix regression in Python 3.12 where types.CodeType.replace() would produce a broken code object if called on a module or class code object that contains a comprehension. Patch by Jelle Zijlstra. - Removed chained classmethod descriptors (introduced in bpo-19072). This can no longer be used to wrap other descriptors such as property. The core design of this feature was flawed and caused a number of downstream problems. To “pass-through” a classmethod, consider using the __wrapped__ attribute that was added in Python 3.10. - Use local events for opcode tracing - Add mimalloc memory allocator support. - When PyConfig.stdlib_dir is explicitly set, it’s now respected and won’t be overridden by PyConfig.home. - Fix incorrect SystemError about AST constructor recursion depth mismatch. - Improve error message for unterminated strings with escapes. - Improved error messages for elif/else statements not matching any valid statements. Patch by Jeremiah Vivian. - Library - Fix SystemError in the TextIOWrapper constructor with non-encodable “errors” argument in non-debug mode. - Added the NI_IDN constant to the socket module when present in C at build time for use with socket.getnameinfo(). - Issue warning message instead of having RuntimeError be displayed when event loop has already been closed at StreamWriter.__del__(). - Fix crashes in io.TextIOWrapper.reconfigure() when pass invalid arguments, e.g. non-string encoding. - curses: restore wide character support (including curses.unget_wch() and get_wch()) on macOS, which was unavailable due to a regression in Python 3.12. - contextlib.suppress now supports suppressing exceptions raised as part of a BaseExceptionGroup, in addition to the recent support for ExceptionGroup. - The mmap.mmap class now has an seekable() method that can be used where it requires a file-like object with seekable and the seek() method return the new absolute position. Patch by Donghee Na. - Remove posix.fallocate() under WASI as the underlying posix_fallocate() is not available in WASI preview2. - Fix truncating arguments on an embedded null character in os.putenv() and os.unsetenv() on Windows. - wsgiref.util.is_hop_by_hop() is now exposed correctly in __all__. - Avoid executing the default function in cmd.Cmd in an except block - Fix doctest for SyntaxError not-builtin subclasses. - Add extra argument validation for alias command in pdb - time: Make time.clock_gettime() and time.clock_gettime_ns() functions up to 2x faster by faster calling convention. Patch by Victor Stinner. - Call loop exception handler for exceptions in client_connected_cb of asyncio.start_server() so that applications can handle it. Patch by Kumar Aditya. - Fix reference leaks in bind_class() and bind_all() methods of tkinter widgets. - asyncio.loop.create_unix_server() will now automatically remove the Unix socket when the server is closed. - Added io.text_encoding(), io.DEFAULT_BUFFER_SIZE, and io.IncrementalNewlineDecoder to io.__all__. - Remove the code to set the REMOTE_HOST header from wsgiref module, as it is unreachable. This header is used for performance reasons, which is not necessary in the wsgiref module. - Speed up pathlib.PurePath.relative_to() and is_relative_to(). - Fixed typo in math.sumprod(). - Remove mention of not supported “vsapi” element type in tkinter.ttk.Style.element_create(). Add tests for element_create() and other ttk.Style methods. Add examples for element_create() in the documentation. - Add show_group parameter to traceback.format_exception_only(), which allows to format ExceptionGroup instances. - Another attempt at fixing asyncio.Server.wait_closed(). It now blocks until both conditions are true: the server is closed, and there are no more active connections. (This means that in some cases where in 3.12.0 this function would incorrectly have returned immediately, it will now block; in particular, when there are no active connections but the server hasn’t been closed yet.) - Optimize recursive wildcards in pathlib. - Fix time not checking for errors when initializing. - Add error checking during _socket module init. - Fix _blake2 not checking for errors when initializing. - Fix select not checking for errors when initializing. - Fix ssl not checking for errors when initializing. - Fix crash in io.BytesIO.getbuffer() called repeatedly for empty BytesIO. - Postpone removal version for locale.getdefaultlocale() to Python 3.15. - Fix doctest output comparison for exceptions with notes. - Fix invalid state handling in asyncio.TaskGroup and asyncio.Timeout. They now raise proper RuntimeError if they are improperly used and are left in consistent state after this. - Make turtledemo run without default root enabled. - Support alias and convenience vars for pdb completion - Added newline parameter to pathlib.Path.read_text(). Patch by Junya Okabe. - Make pdb enter post-mortem mode even for SyntaxError - Set f_trace_lines = True on all frames upon pdb.set_trace() - Expose the setup and cleanup portions of asyncio.run_forever() as the standalone methods asyncio.run_forever_setup() and asyncio.run_forever_cleanup(). This allows for tighter integration with GUI event loops. - Support setting the asyncio.Runner loop_factory kwarg in unittest.IsolatedAsyncioTestCase - Fix tty.setraw() and tty.setcbreak(): previously they returned partially modified list of the original tty attributes. tty.cfmakeraw() and tty.cfmakecbreak() now make a copy of the list of special characters before modifying it. - Make line number of function breakpoint more precise in pdb - Emit deprecation warning for non-integer numbers in gettext functions and methods that consider plural forms even if the translation was not found. - Ensure that select.kqueue() objects correctly appear as closed in forked children, to prevent operations on an invalid file descriptor. - Add __reduce__ method to IPv6Address in order to keep scope_id - Improve errors for unsupported look-behind patterns. Now re.error is raised instead of OverflowError or RuntimeError for too large width of look-behind pattern. - Add the ipaddress.IPv4Address.ipv6_mapped property, which retuns the IPv4-mapped IPv6 address. - Implement the CLI of the symtable module and improve the repr of Symbol. - Improved error handling in pdb command line interface, making it produce more concise error messages. - Change compileall to only strip the stripdir prefix from . Prthe full path recorded in the compiled .pyc file, when . Prthe prefix matches the start of the full path in its . Prentirety. When the prefix does not match, no stripping . Pris performed and a warning to this effect is displayed . Previously all path components of the stripdir prefix that . Prmatched the full path were removed, while those that did . Prnot match were left alone (including ones interspersed . Prbetween matching components) . - Make the DictProxy and ListProxy types in multiprocessing.managers Generic Alias Types for [] use in typing contexts. - Add glob.translate(). This function converts a pathname with shell-style wildcards to a regular expression. - Define USE_XATTRS on Cygwin so that XATTR-related functions in the os module become available. - New methods mailbox.Maildir.get_info(), mailbox.Maildir.set_info(), mailbox.Maildir.get_flags(), mailbox.Maildir.set_flags(), mailbox.Maildir.add_flag(), mailbox.Maildir.remove_flag(). These methods speed up accessing a message’s info and/or flags and are useful when it is not necessary to access the message’s contents, as when iterating over a Maildir to find messages with specific flags. - Fix returning of empty byte strings after seek in zipfile module - Added a parameter local_exit for code.interact() to prevent exit() and quit from closing sys.stdin and raise SystemExit. - Change the behavior of tkinter.Text.count(). It now always returns an integer if one or less counting options are specified. Previously it could return a single count as a 1-tuple, an integer (only if option "update" was specified) or None if no items found. The result is now the same if wantobjects is set to 0. - Switch the storage of the unicode codepoint names to use a different data-structure, a directed acyclic word graph. This makes the unicodedata shared library about 440 KiB smaller. Contributed by Carl Friedrich Bolz-Tereick using code from the PyPy project. - Omit the interface scope from an IPv6 address when used as Host header by http.client. - zipinfo now supports the full range of values in the TZ string determined by RFC 8536 and detects all invalid formats. Both Python and C implementations now raise exceptions of the same type on invalid data. - Tests - Make the default value of test.support.infinite_recursion() to be conditional based on whether optimizations were used when compiling the interpreter. This helps with platforms like WASI whose stack size is greatly restricted in debug builds. - Gathering line coverage of standard libraries within the regression test suite is now precise, as well as much faster. Patch by Łukasz Langa. - Make regrtest --verbose3 option compatible with --huntrleaks -jN options. The ./python -m test -j1 -R 3:3 --verbose3 command now works as expected. Patch by Victor Stinner. - Remove no longer used functions run_unittest() and run_doctest() from the test.support module. - Fix regrtest if the SOURCE_DATE_EPOCH environment variable is defined: use the variable value as the random seed. Patch by Victor Stinner. - test_gdb: Fix detection of gdb built without Python scripting support. Patch by Victor Stinner. - Test case matching patterns specified by options --match, --ignore, --matchfile and --ignorefile are now tested in the order of specification, and the last match determines whether the test case be run or ignored. - Add unit test for usercustomize and sitecustomize hooks from site. - Build - Make make regen-unicodedata work for out-of-tree builds of CPython. - Add Tools/build/regen-configure.sh script to regenerate the configure with an Ubuntu container image. The quay.io/tiran/cpython_autoconf:271 container image (tiran/cpython_autoconf) is no longer used. Patch by Victor Stinner. - For wasi-threads, memory is now exported to fix compatibility issues with some wasm runtimes. - AIX 32bit needs -latomic to build the _testcapi extension module. - The errno, md5, resource, winsound, _ctypes_test, _multiprocessing.posixshmem, _scproxy, _stat, _testimportmultiple and _uuid C extensions are now built with the limited C API. Patch by Victor Stinner. - IDLE - Add docstrings to the IDLE debugger module. Fix two bugs: initialize Idb.botframe (should be in Bdb); in Idb.in_rpc_code, check whether prev_frame is None before trying to use it. Greatly expand test_debugger. - Tools/Demos - Argument Clinic now supports the @critical_section directive that instructs Argument Clinic to generate a critical section around the function call, which locks the self object in --disable-gil builds. Patch by Sam Gross. - C API - Add again the private _PyThreadState_UncheckedGet() function as an alias to the new public PyThreadState_GetUnchecked() function. Patch by Victor Stinner. - Restore the removed _PyDict_GetItemStringWithError() function. It is used by numpy. Patch by Victor Stinner. - Restore removed private C API functions, macros and structures which have no simple replacement for now: _PyDict_GetItem_KnownHash() _PyDict_NewPresized() _PyHASH_BITS _PyHASH_IMAG _PyHASH_INF _PyHASH_MODULUS _PyHASH_MULTIPLIER _PyLong_Copy() _PyLong_FromDigits() _PyLong_New() _PyLong_Sign() _PyObject_CallMethodId() _PyObject_CallMethodNoArgs() _PyObject_CallMethodOneArg() _PyObject_CallOneArg() _PyObject_EXTRA_INIT _PyObject_FastCallDict() _PyObject_GetAttrId() _PyObject_Vectorcall() _PyObject_VectorcallMethod() _PyStack_AsDict() _PyThread_CurrentFrames() _PyUnicodeWriter structure _PyUnicodeWriter_Dealloc() _PyUnicodeWriter_Finish() _PyUnicodeWriter_Init() _PyUnicodeWriter_Prepare() _PyUnicodeWriter_PrepareKind() _PyUnicodeWriter_WriteASCIIString() _PyUnicodeWriter_WriteChar() _PyUnicodeWriter_WriteLatin1String() _PyUnicodeWriter_WriteStr() _PyUnicodeWriter_WriteSubstring() _PyUnicode_AsString() _PyUnicode_FromId() _PyVectorcall_Function() _Py_IDENTIFIER() _Py_c_abs() _Py_c_diff() _Py_c_neg() _Py_c_pow() _Py_c_prod() _Py_c_quot() _Py_c_sum() _Py_static_string() _Py_static_string_init() - Add again and includes in Python.h, but don’t include them in the limited C API version 3.13 and newer. Patch by Victor Stinner. - Add internal-only one-time initialization API: _PyOnceFlag and _PyOnceFlag_CallOnce. - Add PyDict_Pop() and PyDict_PopString() functions: remove a key from a dictionary and optionally return the removed value. This is similar to dict.pop(), but without the default value and not raising KeyError if the key missing. Patch by Stefan Behnel and Victor Stinner. - Rename Py_NOGIL to Py_GIL_DISABLED. Patch by Hugo van Kemenade. - Add PyList_Extend() and PyList_Clear() functions: similar to Python list.extend() and list.clear() methods. Patch by Victor Stinner. - On Windows, Python.h no longer includes the standard header file. If needed, it should now be included explicitly. Patch by Victor Stinner. - Implement “Python Critical Sections” from PEP 703. These are macros to help replace the GIL with per-object locks in the --disable-gil build of CPython. The macros are no-ops in the default build. - In the limited C API version 3.13, Py_SET_REFCNT() function is now implemented as an opaque function call. Patch by Victor Stinner. - Add PyErr_FormatUnraisable() function. - Move the undocumented private _PyArg functions and _PyArg_Parser structure to internal C API (pycore_modsupport.h). Patch by Victor Stinner. - Support non-ASCII keyword names in PyArg_ParseTupleAndKeywords(). - Introduced PyUnstable_PerfTrampoline_CompileCode(), PyUnstable_PerfTrampoline_SetPersistAfterFork() and PyUnstable_CopyPerfMapFile(). These functions allow extension modules to initialize trampolines eagerly, after the application is “warmed up”. This makes it possible to have perf-trampolines running in an always-enabled fashion. - Add the PySys_Audit() function to the limited C API. Patch by Victor Stinner. - Add PyMem_RawMalloc(), PyMem_RawCalloc(), PyMem_RawRealloc() and PyMem_RawFree() to the limited C API. Patch by Victor Stinner. - Functions PyDict_GetItem(), PyDict_GetItemString(), PyMapping_HasKey(), PyMapping_HasKeyString(), PyObject_HasAttr(), PyObject_HasAttrString(), and PySys_GetObject(), which clear all errors occurred during calling the function, report now them using sys.unraisablehook(). - Remove redundant C-contiguity check in getargs.c, binascii, ssl and Argument Clinic. Patched by Stefan Krah and Furkan Onder - Adjust patches: - bpo-31046_ensurepip_honours_prefix.patch - fix_configure_rst.patch - python-3.3.0b1-fix_date_time_compiler.patch - python-3.3.0b1-test-posix_fadvise.patch ------------------------------------------------------------------- Fri Oct 13 17:35:43 UTC 2023 - Daniel Garcia - Update to 3.13.0a1: * Allow the count argument of str.replace() to be a keyword. (Contributed by Hugo van Kemenade in gh-106487.) * Compiler now strip indents from docstrings. This will reduce the size of bytecode cache (e.g. .pyc file). For example, cache file size for sqlalchemy.orm.session in SQLAlchemy 2.0 is reduced by about 5%. This change will affect tools using docstrings, like doctest. (Contributed by Inada Naoki in gh-81283.) * The compile() built-in can now accept a new flag, ast.PyCF_OPTIMIZED_AST, which is similar to ast.PyCF_ONLY_AST except that the returned AST is optimized according to the value of the optimize argument. (Contributed by Irit Katriel in gh-108113). * multiprocessing, concurrent.futures, compileall: Replace os.cpu_count() with os.process_cpu_count() to select the default number of worker threads and processes. Get the CPU affinity if supported. (Contributed by Victor Stinner in gh-109649.) * os.path.realpath() now resolves MS-DOS style file names even if the file is not accessible.

The library changes focus on cleaning up deprecated APIs, usability, and correctness. Of note, the distutils package has been removed from the standard library. Filesystem support in os and pathlib has seen a number of improvements, and several modules have better performance. The language changes focus on usability, as f-strings have had many limitations removed and ‘Did you mean …’ suggestions continue to improve. The new type parameter syntax and type statement improve ergonomics for using generic types and type aliases with static type checkers. This article doesn’t attempt to provide a complete specification of all new features, but instead gives a convenient overview. For full details, you should refer to the documentation, such as the Library Reference and Language Reference. If you want to understand the complete implementation and design rationale for a change, refer to the PEP for a particular new feature; but note that PEPs usually are not kept up-to-date once a feature has been fully implemented. - New syntax features: - PEP 695, type parameter syntax and the type statement - New grammar features: - PEP 701, f-strings in the grammar - Interpreter improvements: - PEP 684, a unique per-interpreter GIL - PEP 669, low impact monitoring - Improved ‘Did you mean …’ suggestions for NameError, ImportError, and SyntaxError exceptions - Python data model improvements: - PEP 688, using the buffer protocol from Python - Significant improvements in the standard library: - The pathlib.Path class now supports subclassing - The os module received several improvements for Windows support - A command-line interface has been added to the sqlite3 module - isinstance() checks against runtime-checkable protocols enjoy a speed up of between two and 20 times - The asyncio package has had a number of performance improvements, with some benchmarks showing a 75% speed up. - A command-line interface has been added to the uuid module - Due to the changes in PEP 701, producing tokens via the tokenize module is up to up to 64% faster. - Security improvements: - Replace the builtin hashlib implementations of SHA1, SHA3, SHA2-384, SHA2-512, and MD5 with formally verified code from the HACL* project. These builtin implementations remain as fallbacks that are only used when OpenSSL does not provide them. - C API improvements: - PEP 697, unstable C API tier - PEP 683, immortal objects - CPython implementation improvements: - PEP 709, comprehension inlining - CPython support for the Linux perf profiler - Implement stack overflow protection on supported platforms - New typing features: - PEP 692, using TypedDict to annotate **kwargs - PEP 698, typing.override() decorator - Important deprecations, removals or restrictions: - PEP 623: Remove wstr from Unicode objects in Python’s C API, reducing the size of every str object by at least 8 bytes. - PEP 632: Remove the distutils package. See the migration guide for advice replacing the APIs it provided. The third-party Setuptools package continues to provide distutils, if you still require it in Python 3.12 and beyond. - gh-95299: Do not pre-install setuptools in virtual environments created with venv. This means that distutils, setuptools, pkg_resources, and easy_install will no longer available by default; to access these run pip install setuptools in the activated virtual environment. - The asynchat, asyncore, and imp modules have been removed, along with several unittest.TestCase method aliases. - Refresh bluez-devel-vendor.tar.xz from bluez-devel 5.69-1.1. ------------------------------------------------------------------- Wed Sep 20 07:14:17 UTC 2023 - Daniel Garcia - Update to 3.12.0rc3: - Core and Builtins - gh-109496: On a Python built in debug mode, Py_DECREF() now calls _Py_NegativeRefcount() if the object is a dangling pointer to deallocated memory: memory filled with 0xDD “dead byte” by the debug hook on memory allocators. The fix is to check the reference count before checking for _Py_IsImmortal(). Patch by Victor Stinner. - gh-109371: Deopted instructions correctly for tool initialization and modified the incorrect assertion in instrumentation, when a previous tool already sets INSTRUCTION events - gh-105658: Fix bug where the line trace of an except block ending with a conditional includes an excess event with the line of the conditional expression. - gh-109219: Fix compiling type param scopes that use a name which is also free in an inner scope. - gh-109341: Fix crash when compiling an invalid AST involving a ast.TypeAlias. - gh-109195: Fix source location for the LOAD_* instruction preceding a LOAD_SUPER_ATTR to load the super global (or shadowing variable) so that it encompasses only the name super and not the following parentheses. - gh-109118: Disallow nested scopes (lambdas, generator expressions, and comprehensions) within PEP 695 annotation scopes that are nested within classes. - gh-109114: Relax the detection of the error message for invalid lambdas inside f-strings to not search for arbitrary replacement fields to avoid false positives. Patch by Pablo Galindo - gh-109118: Fix interpreter crash when a NameError is raised inside the type parameters of a generic class. - gh-108976: Fix crash that occurs after de-instrumenting a code object in a monitoring callback. - gh-108732: Make iteration variables of module- and class-scoped comprehensions visible to pdb and other tools that use frame.f_locals again. - gh-108959: Fix caret placement for error locations for subscript and binary operations that involve non-semantic parentheses and spaces. Patch by Pablo Galindo - Library - gh-108682: Enum: require names=() or type=... to create an empty enum using the functional syntax. - gh-108843: Fix an issue in ast.unparse() when unparsing f-strings containing many quote types. - Documentation - gh-102823: Document the return type of x // y when x and y have type float. - Tests - gh-109396: Fix test_socket.test_hmac_sha1() in FIPS mode. Use a longer key: FIPS mode requires at least of at least 112 bits. The previous key was only 32 bits. Patch by Victor Stinner. - gh-104736: Fix test_gdb on Python built with LLVM clang 16 on Linux ppc64le (ex: Fedora 38). Search patterns in gdb “bt” command output to detect when gdb fails to retrieve the traceback. For example, skip a test if Backtrace stopped: frame did not save the PC is found. Patch by Victor Stinner. - gh-109237: Fix test_site.test_underpth_basic() when the working directory contains at least one non-ASCII character: encode the ._pth file to UTF-8 and enable the UTF-8 Mode to use UTF-8 for the child process stdout. Patch by Victor Stinner. - gh-109230: Fix test_pyexpat.test_exception(): it can now be run from a directory different than Python source code directory. Before, the test failed in this case. Skip the test if Modules/pyexpat.c source is not available. Skip also the test on Python implementations other than CPython. Patch by Victor Stinner. - gh-109015: Fix test_asyncio, test_imaplib and test_socket tests on FreeBSD if the TCP blackhole is enabled (sysctl net.inet.tcp.blackhole). Skip the few tests which failed with ETIMEDOUT which such non standard configuration. Currently, the FreeBSD GCP image enables TCP and UDP blackhole (sysctl net.inet.tcp.blackhole=2 and sysctl net.inet.udp.blackhole=1). Patch by Victor Stinner. - gh-91960: Skip test_gdb if gdb is unable to retrieve Python frame objects: if a frame is . When Python is built with “clang -Og”, gdb can fail to retrive the frame parameter of _PyEval_EvalFrameDefault(). In this case, tests like py_bt() are likely to fail. Without getting access to Python frames, python-gdb.py is mostly clueless on retrieving the Python traceback. Moreover, test_gdb is no longer skipped on macOS if Python is built with Clang. Patch by Victor Stinner. - gh-108962: Skip test_tempfile.test_flags() if chflags() fails with “OSError: [Errno 45] Operation not supported” (ex: on FreeBSD 13). Patch by Victor Stinner. - gh-108851: Fix test_tomllib recursion tests for WASI buildbots: reduce the recursion limit and compute the maximum nested array/dict depending on the current available recursion limit. Patch by Victor Stinner. - gh-108851: Add get_recursion_available() and get_recursion_depth() functions to the test.support module. Patch by Victor Stinner. - gh-108834: Add --fail-rerun option option to regrtest: if a test failed when then passed when rerun in verbose mode, exit the process with exit code 2 (error), instead of exit code 0 (success). Patch by Victor Stinner. - gh-108834: Rename regrtest --verbose2 option (-w) to --rerun. Keep --verbose2 as a deprecated alias. Patch by Victor Stinner. - gh-108834: When regrtest reruns failed tests in verbose mode (./python -m test --rerun), tests are now rerun in fresh worker processes rather than being executed in the main process. If a test does crash or is killed by a timeout, the main process can detect and handle the killed worker process. Tests are rerun in parallel if the -jN option is used to run tests in parallel. Patch by Victor Stinner. - gh-103186: Suppress and assert expected RuntimeWarnings in test_sys_settrace.py - Build - gh-108740: Fix a race condition in make regen-all. The deepfreeze.c source and files generated by Argument Clinic are now generated or updated before generating “global objects”. Previously, some identifiers may miss depending on the order in which these files were generated. Patch by Victor Stinner. - Python 3.12.0 release candidate 2: - Security - gh-108310: Fixed an issue where instances of ssl.SSLSocket were vulnerable to a bypass of the TLS handshake and included protections (like certificate verification) and treating sent unencrypted data as if it were post-handshake TLS encrypted data. Security issue reported as CVE-2023-40217 by Aapo Oksman. Patch by Gregory P. Smith. - gh-107774: PEP 669 specifies that sys.monitoring.register_callback will generate an audit event. Pre-releases of Python 3.12 did not generate the audit event. This is now fixed. - Core and Builtins - gh-108520: Fix multiprocessing.synchronize.SemLock.__setstate__() to properly initialize multiprocessing.synchronize.SemLock._is_fork_ctx. This fixes a regression when passing a SemLock accross nested processes. - Rename multiprocessing.synchronize.SemLock.is_fork_ctx to multiprocessing.synchronize.SemLock._is_fork_ctx to avoid exposing it as public API. - gh-108654: Restore locals shadowed by an inlined comprehension if the comprehension raises an exception. - gh-108487: Change an assert that would cause a spurious crash in a devious case that should only trigger deoptimization. - gh-106176: Use a WeakValueDictionary to track the lists containing the modules each thread is currently importing. This helps avoid a reference leak from keeping the list around longer than necessary. Weakrefs are used as GC can’t interrupt the cleanup. - gh-107901: Fix missing line number on JUMP_BACKWARD at the end of a for loop. - gh-108390: Raise an exception when setting a non-local event (RAISE, EXCEPTION_HANDLED, etc.) in sys.monitoring.set_local_events. - Fixes crash when tracing in recursive calls to Python classes. - gh-91051: Fix abort / segfault when using all eight type watcher slots, on platforms where char is signed by default. - gh-107724: In pre-release versions of 3.12, up to rc1, the sys.monitoring callback function for the PY_THROW event was missing the third, exception argument. That is now fixed. - gh-107080: Trace refs builds (--with-trace-refs) were crashing when used with isolated subinterpreters. The problematic global state has been isolated to each interpreter. Other fixing the crashes, this change does not affect users. - gh-77377: Ensure that multiprocessing synchronization objects created in a fork context are not sent to a different process created in a spawn context. This changes a segfault into an actionable RuntimeError in the parent process. - Library - gh-108469: ast.unparse() now supports new f-string syntax introduced in Python 3.12. Note that the f-string quotes are reselected for simplicity under the new syntax. (Patch by Steven Sun) - gh-108682: Enum: raise TypeError if super().__new__() is called from a custom __new__. - gh-108295: Fix crashes related to use of weakrefs on typing.TypeVar. - gh-64662: Fix support for virtual tables in sqlite3.Connection.iterdump(). Patch by Aviv Palivoda. - gh-108111: Fix a regression introduced in gh-101251 for 3.12, resulting in an incorrect offset calculation in gzip.GzipFile.seek(). - gh-105736: Harmonized the pure Python version of OrderedDict with the C version. Now, both versions set up their internal state in __new__. Formerly, the pure Python version did the set up in __init__. - gh-108083: Fix bugs in the constructor of sqlite3.Connection and sqlite3.Connection.close() where exceptions could be leaked. Patch by Erlend E. Aasland. - gh-107963: Fix multiprocessing.set_forkserver_preload() to check the given list of modules names. Patch by Dong-hee Na. - gh-106242: Fixes os.path.normpath() to handle embedded null characters without truncating the path. - gh-107913: Fix possible losses of errno and winerror values in OSError exceptions if they were cleared or modified by the cleanup code before creating the exception object. - gh-107845: tarfile.data_filter() now takes the location of symlinks into account when determining their target, so it will no longer reject some valid tarballs with LinkOutsideDestinationError. - gh-107805: Fix signatures of module-level generated functions in turtle. - gh-107715: Fix doctest.DocTestFinder.find() in presence of class names with special characters. Patch by Gertjan van Zwieten. - gh-100814: Passing a callable object as an option value to a Tkinter image now raises the expected TclError instead of an AttributeError. - gh-106684: Close asyncio.StreamWriter when it is not closed by application leading to memory leaks. Patch by Kumar Aditya. - gh-107396: tarfiles; Fixed use before assignment of self.exception for gzip decompression - gh-106052: re module: fix the matching of possessive quantifiers in the case of a subpattern containing backtracking. - gh-100061: Fix a bug that causes wrong matches for regular expressions with possessive qualifier. - gh-99203: Restore following CPython <= 3.10.5 behavior of shutil.make_archive(): do not create an empty archive if root_dir is not a directory, and, in that case, raise FileNotFoundError or NotADirectoryError regardless of format choice. Beyond the brought-back behavior, the function may now also raise these exceptions in dry_run mode. - Documentation - gh-105052: Update timeit doc to specify that time in seconds is just the default. - Tests - gh-89392: Removed support of test_main() function in tests. They now always use normal unittest test runner. - gh-108388: Convert test_concurrent_futures to a package of 7 sub-tests. Patch by Victor Stinner. - gh-108388: Split test_multiprocessing_fork, test_multiprocessing_forkserver and test_multiprocessing_spawn into test packages. Each package is made of 4 sub-tests: processes, threads, manager and misc. It allows running more tests in parallel and so reduce the total test duration. Patch by Victor Stinner. - gh-105776: Fix test_cppext when the C compiler command -std=c11 option: remove -std= options from the compiler command. Patch by Victor Stinner. - gh-107178: Add the C API test for functions in the Mapping Protocol, the Sequence Protocol and some functions in the Object Protocol. - Build - gh-63760: Fix Solaris build: no longer redefine the gethostname() function. Solaris defines the function since 2005. Patch by Victor Stinner, original patch by Jakub Kulík. - gh-107814: When calling find_python.bat with -q it did not properly silence the output of nuget. That is now fixed. - Windows - gh-107565: Update Windows build to use OpenSSL 3.0.10. - gh-106242: Fixes realpath() to behave consistently when passed a path containing an embedded null character on Windows. In strict mode, it now raises OSError instead of the unexpected ValueError, and in non-strict mode will make the path absolute. - gh-106844: Fix integer overflow and truncating by the null character in _winapi.LCMapStringEx() which affects ntpath.normcase(). - macOS - gh-107565: Update macOS installer to use OpenSSL 3.0.10. - Tools/Demos - gh-107565: Update multissltests and GitHub CI workflows to use OpenSSL 1.1.1v, 3.0.10, and 3.1.2. - gh-95065: Argument Clinic now supports overriding automatically generated signature by using directive @text_signature. - C API - gh-107916: C API functions PyErr_SetFromErrnoWithFilename(), PyErr_SetExcFromWindowsErrWithFilename() and PyErr_SetFromWindowsErrWithFilename() save now the error code before calling PyUnicode_DecodeFSDefault(). - gh-107915: Such C API functions as PyErr_SetString(), PyErr_Format(), PyErr_SetFromErrnoWithFilename() and many others no longer crash or ignore errors if it failed to format the error message or decode the filename. Instead, they keep a corresponding error. - gh-107810: Improve DeprecationWarning for uses of PyType_Spec with metaclasses that have custom tp_new. ------------------------------------------------------------------- Thu Aug 10 09:33:26 UTC 2023 - Dirk Müller - restrict PEP668 to ALP/Tumbleweed ------------------------------------------------------------------- Mon Aug 7 07:31:27 UTC 2023 - Daniel Garcia - Refresh all patches - Drop Revert-gh105127-left-tests.patch, in upstream now - Update to 3.12.0rc1: - Reverted the :mod:`email.utils` security improvement change released in 3.12beta4 that unintentionally caused :mod:`email.utils.getaddresses` to fail to parse email addresses with a comma in the quoted name field. See :gh:`106669`. - Start initializing ob_digit during creation of :c:type:`PyLongObject` objects. Patch by Illia Volochii. - Increase C recursion limit for functions other than the main interpreter from 800 to 1500. This should allow functions like list.__repr__ and json.dumps to handle all the inputs that they could prior to 3.12 - Fix potential unaligned memory access on C APIs involving returned sequences of char * pointers within the :mod:`grp` and :mod:`socket` modules. These were revealed using a -fsaniziter=alignment build on ARM macOS. Patch by Christopher Chavez. - Add the exception as the third argument to PY_UNIND callbacks in sys.monitoring. This makes the PY_UNWIND callback consistent with the other exception hanlding callbacks. - Raise a ValueError when a monitoring callback funtion returns DISABLE for events that cannot be disabled locally. - Add a RERAISE event to sys.monitoring, which occurs when an exception is reraised, either explicitly by a plain raise statement, or implicitly in an except or finally block. - Unsupported modules now always fail to be imported. - Fix classmethod-style :func:`super` method calls (i.e., where the second argument to :func:`super`, or the implied second argument drawn from self/cls in the case of zero-arg super, is a type) when the target of the call is not a classmethod. - Python no longer crashes due an infrequent race when initialzing per-interpreter interned strings. The crash would manifest when the interpreter was finalized. - Python no longer crashes due to an infrequent race in setting Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors (both deprecated), when simultaneously initializing two isolated subinterpreters. Now they are only set during runtime initialization. - Fix a segmentation fault caused by a use-after-free bug in frame_dealloc when the trashcan delays the deallocation of a PyFrameObject. - No longer suppress arbitrary errors in the __annotations__ getter and setter in the type and module types. - Propagate frozen_modules to multiprocessing spawned process interpreters. - Prevent out-of-bounds memory access during mmap.find() calls. - Seems that in some conditions, OpenSSL will return SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL when a certification verification has failed, but the error parameters will still contain ERR_LIB_SSL and SSL_R_CERTIFICATE_VERIFY_FAILED. We are now detecting this situation and raising the appropiate ssl.SSLCertVerificationError. Patch by Pablo Galindo - Fix :func:`types.get_original_bases` to only return :attr:`!__orig_bases__` if it is present on cls directly. Patch by James Hilton-Balfe. - Prevent memory leak and use-after-free when using pointers to pointers with ctypes - Make :func:`gettext.pgettext` search plural definitions when translation is not found. - Document behavior of :func:`shutil.disk_usage` for non-mounted filesystems on Unix. - Do not report MultipartInvariantViolationDefect defect when the :class:`email.parser.Parser` class is used to parse emails with headersonly=True. - Fix invalid result from :meth:`PurePath.relative_to` method when attempting to walk a ".." segment in other with walk_up enabled. A :exc:`ValueError` exception is now raised in this case. - Fix potential missing NULL check of d2i_SSL_SESSION result in _ssl.c. - Update the bundled copy of pip to version 23.2.1. - Fixed several bugs in zipfile.Path, including: in Path.match`, Windows separators are no longer honored (and never were meant to be); Fixed ``name/suffix/suffixes/stem operations when no filename is present and the Path is not at the root of the zipfile; Reworked glob for performance and more correct matching behavior. - Add __copy__ and __deepcopy__ in :mod:`enum` - Revert a change to :func:`colorsys.rgb_to_hls` that caused division by zero for certain almost-white inputs. Patch by Terry Jan Reedy. - Instances of :class:`typing.TypeVar`, :class:`typing.ParamSpec`, :class:`typing.ParamSpecArgs`, :class:`typing.ParamSpecKwargs`, and :class:`typing.TypeVarTuple` once again support weak references, fixing a regression introduced in Python 3.12.0 beta 1. Patch by Jelle Zijlstra. - Detect possible memory allocation failure in the libtommath function :c:func:`mp_init` used by the _tkinter module. - Fix crash when calling repr with a manually constructed SignalDict object. Patch by Charlie Zhao. - Change the default return value of :meth:`http.client.HTTPConnection.get_proxy_response_headers` to be None and not {}. - Ensure gettext(msg) retrieve translations even if a plural form exists. In other words: gettext(msg) == ngettext(msg, '', 1). - Add documentation for :c:type:`PyInterpreterConfig` and :c:func:`Py_NewInterpreterFromConfig`. Also clarify some of the nearby docs relative to per-interpreter GIL. - Document the :mod:`curses` module variables :const:`~curses.LINES` and :const:`~curses.COLS`. - Add a number of standard external names to nitpick_ignore. - Add documentation on how to localize the :mod:`argparse` module. - test_logging: Fix test_udp_reconnection() by increasing the timeout from 100 ms to 5 minutes (LONG_TIMEOUT). Patch by Victor Stinner. - test_capi: Fix test_no_FatalError_infinite_loop() to no longer write a coredump, by using test.support.SuppressCrashReport. Patch by Victor Stinner. - Avoid creating a reference to the test object in :meth:`~unittest.TestResult.collectedDurations`. - Moved tests for zipfile.Path into Lib/test/test_zipfile/_path. Made zipfile._path a package. - Check for linux/limits.h before including it in Modules/posixmodule.c. - Detect MPI compilers in :file:`configure`. - Add experimental wasi-threads support. Patch by Takashi Yamamoto. - Update Windows build to use OpenSSL 3.0.9 - Update macOS installer to use OpenSSL 3.0.9. - Fix bugs in the Argument Clinic destination clear command; the destination buffers would never be cleared, and the destination directive parser would simply continue to the fault handler after processing the command. Patch by Erlend E. Aasland. - freeze now fetches CONFIG_ARGS from the original CPython instance the Makefile uses to call utility scripts. Patch by Ijtaba Hussain. - :c:func:`PyModule_AddObjectRef` is now only available in the limited API version 3.10 or later. ------------------------------------------------------------------- Fri Aug 4 06:37:41 UTC 2023 - Dirk Müller - add externally_managed.in to label this build as PEP-668 managed ------------------------------------------------------------------- Thu Aug 3 14:13:30 UTC 2023 - Matej Cepl - IT MEANS THAT bsc#1210638 STILL HAS NOT BEEN FIXED! - Add Revert-gh105127-left-tests.patch (gh#python/cpython!106941) partially reverting CVE-2023-27043-email-parsing-errors.patch, because of the regression in gh#python/cpython#106669. ------------------------------------------------------------------- Tue Jul 11 22:20:22 UTC 2023 - Matej Cepl - Update to 3.12.0b4: - gh-issue-102988: CVE-2023-27043 (bsc#1210638): Prevent :func:`email.utils.parseaddr` and :func:`email.utils.getaddresses` from returning the realname portion of an invalid RFC2822 email header in the email address portion of the 2-tuple returned after being parsed by :class:`email._parseaddr.AddressList`. - gh-issue-106396: When the format specification of an f-string expression is empty, the parser now generates an empty :class:`ast.JoinedStr` node for it instead of an one-element :class:`ast.JoinedStr` with an empty string :class:`ast.Constant`. - gh-issue-106145: Make ``end_lineno`` and ``end_col_offset`` required on ``type_param`` ast nodes. - gh-issue-105979: Fix crash in :func:`!_imp.get_frozen_object` due to improper exception handling. - gh-issue-98931: Ensure custom :exc:`SyntaxError` error messages are raised for invalid imports with multiple targets. Patch by Pablo Galindo - gh-issue-105908: Fixed bug where :gh:`99111` breaks future import ``barry_as_FLUFL`` in the Python REPL. - gh-issue-105340: Include the comprehension iteration variable in ``locals()`` inside a module- or class-scope comprehension. - gh-issue-105486: Change the repr of ``ParamSpec`` list of args in ``types.GenericAlias``. - gh-issue-101006: Improve error handling when read :mod:`marshal` data. - gh-issue-106524: Fix crash in :func:`!_sre.template` with templates containing invalid group indices. - gh-issue-106510: Improve debug output for atomic groups in regular expressions. - gh-issue-106503: Fix ref cycle in :class:`!asyncio._SelectorSocketTransport` by removing ``_write_ready`` in ``close``. - gh-issue-105497: Fix flag mask inversion when unnamed flags exist. - gh-issue-90876: Prevent :mod:`multiprocessing.spawn` from failing to *import* in environments where ``sys.executable`` is ``None``. This regressed in 3.11 with the addition of support for path-like objects in multiprocessing. - gh-issue-106292: Check for an instance-dict cached value in the :meth:`__get__` method of :func:`functools.cached_property`. This better matches the pre-3.12 behavior and improves compatibility for users subclassing :func:`functools.cached_property` and adding a :meth:`__set__` method. - gh-issue-106330: Fix incorrect matching of empty paths in :meth:`pathlib.PurePath.match`. This bug was introduced in Python 3.12.0 beta 1. - gh-issue-102541: Make pydoc.doc catch bad module ImportError when output stream is not None. - gh-issue-106152: Added PY_THROW event hook for :mod:`cProfile` for generators - gh-issue-106075: Added `asyncio.taskgroups.__all__` to `asyncio.__all__` for export in star imports. - gh-issue-105987: Fix crash due to improper reference counting in :mod:`asyncio` eager task factory internal routines. - gh-issue-105974: Fix bug where a :class:`typing.Protocol` class that had one or more non-callable members would raise :exc:`TypeError` when :func:`issubclass` was called against it, even if it defined a custom ``__subclasshook__`` method. The behaviour in Python 3.11 and lower -- which has now been restored -- was not to raise :exc:`TypeError` in these situations if a custom ``__subclasshook__`` method was defined. Patch by Alex Waygood. - gh-issue-96145: Reverted addition of ``json.AttrDict``. - gh-issue-105497: Fix flag inversion when alias/mask members exist. - gh-issue-104554: Add RTSPS scheme support in urllib.parse - gh-issue-94777: Fix hanging :mod:`multiprocessing` ``ProcessPoolExecutor`` when a child process crashes while data is being written in the call queue. - gh-issue-106232: Make timeit doc command lines compatible with Windows by using double quotes for arguments. This works on linux and macOS also. - gh-issue-101634: When running the Python test suite with ``-jN`` option, if a worker stdout cannot be decoded from the locale encoding report a failed testn so the exitcode is non-zero. Patch by Victor Stinner. - gh-issue-106118: Fix compilation for platforms without :data:`!O_CLOEXEC`. The issue was introduced with Python 3.12b1 in :gh:`103295`. Patch by Erlend Aasland. - gh-issue-104692: Include ``commoninstall`` as a prerequisite for ``bininstall`` This ensures that ``commoninstall`` is completed before ``bininstall`` is started when parallel builds are used (``make -j install``), and so the ``python3`` symlink is only installed after all standard library modules are installed. - gh-issue-106359: Argument Clinic now explicitly forbids "kwarg splats" in function calls used as annotations. - gh-issue-105227: The new :c:func:`PyType_GetDict` provides the dictionary for the given type object that is normally exposed by ``cls.__dict__``. Normally it's sufficient to use :c:member:`~PyTypeObject.tp_dict`, but for the static builtin types :c:member:`!tp_dict` is now always ``NULL``. :c:func:`!PyType_GetDict()` provides the correct dict object instead. ------------------------------------------------------------------- Wed Jun 28 19:59:03 UTC 2023 - Matej Cepl - Update to 3.12.0b3: - gh-103142: The version of OpenSSL used in Windows and Mac installers has been upgraded to 1.1.1u to address CVE-2023-2650, CVE-2023-0465, CVE-2023-0466, CVE-2023-0464, as well as CVE-2023-0286, CVE-2022-4303, and CVE-2022-4303 fixed previously in 1.1.1t (gh-101727). - gh-102153: urllib.parse.urlsplit() now strips leading C0 control and space characters following the specification for URLs defined by WHATWG in response to CVE-2023-24329. - gh-99889: Fixed a security in flaw in uu.decode() that could allow for directory traversal based on the input if no out_file was specified. - gh-104049: Do not expose the local on-disk location in directory indexes produced by http.client.SimpleHTTPRequestHandler. - gh-103935: trace.__main__ now uses io.open_code() for files to be executed instead of raw open(). - gh-102953: The extraction methods in tarfile, and shutil.unpack_archive(), have a new filter argument that allows limiting tar features than may be surprising or dangerous, such as creating files outside the destination directory. See Extraction filters for details. - Remove upstreamed patches: - 00398-fix-stack-overwrite-on-32-bit-in-perf-map-test-harness-gh-104811-104823.patch ------------------------------------------------------------------- Thu Jun 1 11:42:58 UTC 2023 - Daniel Garcia - Add 00398-fix-stack-overwrite-on-32-bit-in-perf-map-test-harness-gh-104811-104823.patch gh#python/cpython#104811 ------------------------------------------------------------------- Wed May 31 08:54:44 UTC 2023 - Daniel Garcia - Refresh all patches - Update to 3.12.0b1: Full changelog can be found here https://docs.python.org/dev/whatsnew/changelog.html#python-3-12-0-beta-1 ------------------------------------------------------------------- Sun Apr 30 18:11:57 UTC 2023 - Matej Cepl - Why in the world we download from HTTP? ------------------------------------------------------------------- Thu Apr 27 16:59:09 UTC 2023 - Daniel Garcia - Ignore failing test test_freeze_simple_script, it fails because it cannot import _sysconfigdata__linux_x86_64-linux-gnu that's not present in the test environment, it fails without bundled libs. - Remove non existing paths: * %{sitedir}/tkinter/test * %{sitedir}/sqlite3/test * %{dynlib _curses_panel} ------------------------------------------------------------------- Wed Apr 26 10:55:38 UTC 2023 - Daniel Garcia - Update to 3.12.0a7: Full changelog can be found here https://docs.python.org/dev/whatsnew/changelog.html#python-3-12-0-alpha-7 ------------------------------------------------------------------- Mon Mar 27 15:10:19 UTC 2023 - Matej Cepl - Switch off obsoleting previous interpreters. ------------------------------------------------------------------- Sat Mar 25 22:02:04 UTC 2023 - Matej Cepl - Update to 3.12.0a6: - Many new features for Python 3.12 are still being planned and written. Among the new major new features and changes so far: - Even more improved error messages. More exceptions potentially caused by typos now make suggestions to the user. - Support for the Linux perf profiler to report Python function names in traces. - The deprecated wstr and wstr_length members of the C implementation of unicode objects were removed, per PEP 623. - In the unittest module, a number of long deprecated methods and classes were removed. (They had been deprecated since Python 3.1 or 3.2). - The deprecated smtpd and distutils modules have been removed (see PEP 594 and PEP 632. The setuptools package (installed by default in virtualenvs and many other places) continues to provide the distutils module. - A number of other old, broken and deprecated functions, classes and methods have been removed. - Invalid backslash escape sequences in strings now warn with SyntaxWarning instead of DeprecationWarning, making them more visible. (They will become syntax errors in the future.) - The internal representation of integers has changed in preparation for performance enhancements. (This should not affect most users as it is an internal detail, but it may cause problems for Cython-generated code.) - Add the refreshed version of F00251-change-user-install-location.patch (updated from Fedora), which works together with the installation schemes in sysconfig. - Remove distutils-reproducible-compile.patch, which is not applicable anymore (because distutils was removed from the standard library). - Remove upstreamed support-expat-CVE-2022-25236-patched.patch ------------------------------------------------------------------- Fri Mar 3 17:23:35 UTC 2023 - Matej Cepl - Update to 3.11.2: Bug fixes, no changes in API and no security bugs. ------------------------------------------------------------------- Wed Mar 1 20:50:04 UTC 2023 - Matej Cepl - Add python310 Obsoletes line to obsolete_python_versioned macro. ------------------------------------------------------------------- Tue Feb 21 11:34:49 UTC 2023 - Matej Cepl - Add provides for readline and sqlite3 to the main Python package. ------------------------------------------------------------------- Thu Jan 26 13:28:24 UTC 2023 - Thorsten Kukuk - Disable NIS for new products, it's deprecated and gets removed ------------------------------------------------------------------- Tue Jan 24 12:23:34 UTC 2023 - Dirk Müller - build GLIBC hwcaps optimized versions of the interpreter ------------------------------------------------------------------- Tue Jan 10 11:11:56 UTC 2023 - Matej Cepl - Don't fail on Sphinx build warnings. - For jsc#PED-1570, providing Python 3.11 for SLE-15-SP5. ------------------------------------------------------------------- Thu Dec 8 14:59:50 UTC 2022 - Matej Cepl - Update to 3.11.1: - python -m http.server no longer allows terminal control characters sent within a garbage request to be printed to the stderr server lo This is done by changing the http.server BaseHTTPRequestHandler .log_message method to replace control characters with a \xHH hex escape before printin - Avoid publishing list of active per-interpreter audit hooks via the gc module - The IDNA codec decoder used on DNS hostnames by socket or asyncio related name resolution functions no longer involves a quadratic algorithm. This prevents a potential CPU denial of service if an out-of-spec excessive length hostname involving bidirectional characters were decoded. Some protocols such as urllib http 3xx redirects potentially allow for an attacker to supply such a name (CVE-2022-45061). - Update bundled libexpat to 2.5.0 - Fix a shell code injection vulnerability in the get-remote-certificate.py example script. The script no longer uses a shell to run openssl commands. Issue reported and initial fix by Caleb Shortt. Patch by Victor Stinner. - Fix a crash when an object which does not have a dictionary frees its instance values. - Fix a bug in the tokenizer that could cause infinite recursion when showing syntax warnings that happen in the first line of the source. Patch by Pablo Galindo - Fix an issue that could cause frames to be visible to Python code as they are being torn down, possibly leading to memory corruption or hard crashes of the interpreter. - Fix a reference bug in _imp.create_builtin() after the creation of the first sub-interpreter for modules builtins and sys. Patch by Victor Stinner. - Fixed a bug that was causing a buffer overflow if the tokenizer copies a line missing the newline caracter from a file that is as long as the available tokenizer buffer. Patch by Pablo galindo - Fix bug where an ExceptionGroup subclass can wrap a BaseException. - Fix zip path for venv created from a non-installed python on POSIX platforms. - Fix an issue that could potentially cause incorrect error handling for some bytecode instructions. - Fix an issue that prevented PyThreadState and PyInterpreterState memory from being freed properly. - Fix failure in except* with unhashable exceptions. - Fix calculation of sys._base_executable when inside a POSIX virtual environment using copies of the python binary when the base installation does not provide the executable name used by the venv. Calculation will fall back to alternative names (“python”, “python.”). - Update faulthandler to emit an error message with the proper unexpected signal number. Patch by Dong-hee Na. - Fix location of SyntaxError for a try block with both except and except*. - Fix the error reporting positions of specialized traceback anchors when the source line contains Unicode characters. - Fix subscription of type aliases containing bare generic types or types like TypeVar: for example tuple[A, T][int] and tuple[TypeVar, T][int], where A is a generic type, and T is a type variable. - Lower the recursion depth for marshal on WASI to support wasmtime 2.0/main. - Fix multiple crashes in debug mode when str subclasses are used instead of str itself. - Fix an issue where member descriptors (such as those for __slots__) could behave incorrectly or crash instead of raising a TypeError when accessed via an instance of an invalid type. - Suppress ImportError for invalid query for help() command. Patch by Dong-hee Na. - Fix detection of MAC addresses for uuid on certain OSs. Patch by Chaim Sanders - Print exception class name instead of its string representation when raising errors from ctypes calls. - os.sched_yield() now release the GIL while calling sched_yield(2). Patch by Dong-hee Na. - Fix an issue that could delay the specialization of PRECALL instructions. - Bugfix: PyFunction_GetAnnotations() should return a borrowed reference. It was returning a new reference. - Ensure that all Python frame objects are backed by “complete” frames. - Fixed a missing incref/decref pair in Exception.__setstate__(). Patch by Ofey Chan. - Fix the Python path configuration used to initialized sys.path at Python startup. Paths are no longer encoded to UTF-8/strict to avoid encoding errors if it contains surrogate characters (bytes paths are decoded with the surrogateescape error handler). Patch by Victor Stinner. - Fix overly-broad source position information for chained comparisons used as branching conditions. - At Python exit, sometimes a thread holding the GIL can wait forever for a thread (usually a daemon thread) which requested to drop the GIL, whereas the thread already exited. To fix the race condition, the thread which requested the GIL drop now resets its request before exiting. Issue discovered and analyzed by Mingliang ZHAO. Patch by Victor Stinner. - Fix a possible assertion failure, fatal error, or SystemError if a line tracing event raises an exception while opcode tracing is enabled. - Fix undefined behaviour in C code of null pointer arithmetic. - Make sure that all frame objects created are created from valid interpreter frames. Prevents the possibility of invalid frames in backtraces and signal handlers. - Disable incorrect pickling of the C implemented classmethod descriptors. - On WASI ENOTCAPABLE is now mapped to PermissionError. The errno modules exposes the new error number. getpath.py now ignores PermissionError when it cannot open landmark files pybuilddir.txt and pyenv.cfg. - Allow pdb to locate source for frozen modules in the standard library. - Raise ValueError instead of SystemError when methods of uninitialized io.IncrementalNewlineDecoder objects are called. Patch by Oren Milman. - Fix a possible assertion failure in io.FileIO when the opener returns an invalid file descriptor. - Also escape s in the http.server BaseHTTPRequestHandler.log_message so that it is technically possible to parse the line and reconstruct what the original data was. Without this a xHH is ambiguious as to if it is a hex replacement we put in or the characters r”x” came through in the original request line. - asyncio.get_event_loop() now only emits a deprecation warning when a new event loop was created implicitly. It no longer emits a deprecation warning if the current event loop was set. - Fix bug when calling trace.CoverageResults with valid infile. - Fix a bug in handling class cleanups in unittest.TestCase. Now addClassCleanup() uses separate lists for different TestCase subclasses, and doClassCleanups() only cleans up the particular class. - Release the GIL when calling termios APIs to avoid blocking threads. - Fix ast.increment_lineno() to also cover ast.TypeIgnore when changing line numbers. - Fix bug in urllib.parse.urlparse() that causes URL schemes that begin with a digit, a plus sign, or a minus sign to be parsed incorrectly. - Check the number of arguments in substitution in user generics containing a TypeVarTuple and one or more TypeVar. - Fix substitution of ParamSpec followed by TypeVarTuple in generic aliases. - Fix substitution of TypeVarTuple and ParamSpec together in user generics. - Fixed bug where inspect.signature() reported incorrect arguments for decorated methods. - Fix SystemError in ctypes when exception was not set during __initsubclass__. - Remove older version of _SSLProtocolTransport.get_write_buffer_limits in asyncio.sslproto - fix negative numbers failing in verify() - Fix statistics.NormalDist pickle with 0 and 1 protocols. - enum.auto() is now correctly activated when combined with other assignment values. E.g. ONE = auto(), 'some text' will now evaluate as (1, 'some text'). - Update the bundled copy of pip to version 22.3.1. - Clean up refleak on failed module initialisation in _zoneinfo - Clean up refleaks on failed module initialisation in in _pickle - Clean up refleak on failed module initialisation in _io. - Fix memory leak in math.dist() when both points don’t have the same dimension. Patch by Kumar Aditya. - [3.11] Applied changes from importlib_metadata 4.11.4 through 4.13, including compatibility and robustness fixes for Distribution objects without _normalized_name, disallowing invalid inputs to Distribution.from_name, and refined behaviors in PathDistribution._name_from_stem and PathDistribution._normalized_name. - Fix argument typechecks in _overlapped.WSAConnect() and _overlapped.Overlapped.WSASendTo() functions. - Prevent crashing in traceback when retrieving the byte-offset for some source files that contain certain unicode characters. - Fix internal error in the re module which in very rare circumstances prevented compilation of a regular expression containing a conditional expression without the “else” branch. - Fix asyncio.StreamWriter.drain() to call protocol.connection_lost callback only once on Windows. - Add a mutex to unittest.mock.NonCallableMock to protect concurrent access to mock attributes. - Fix hang on Windows in subprocess.wait_closed() in asyncio with ProactorEventLoop. Patch by Kumar Aditya. - Fix infinite loop in unittest when a self-referencing chained exception is raised - tkinter.Text.count() raises now an exception for options starting with “-” instead of silently ignoring them. - On uname_result, restored expectation that _fields and _asdict would include all six properties including processor. - A createSocket() method was added to SysLogHandler. - Fix bug in urllib.parse.urlparse() that causes certain port numbers containing whitespace, underscores, plus and minus signs, or non-ASCII digits to be incorrectly accepted. - Allow venv to pass along PYTHON* variables to ensurepip and pip when they do not impact path resolution - On macOS, fix a crash in syslog.syslog() in multi-threaded applications. On macOS, the libc syslog() function is not thread-safe, so syslog.syslog() no longer releases the GIL to call it. Patch by Victor Stinner. - Allow BUILTINS to be a valid field name for frozen dataclasses. - Wrap network errors consistently in urllib FTP support, so the test suite doesn’t fail when a network is available but the public internet is not reachable. - Make sure patch.dict() can be applied on async functions. - Earlier in 3.11 we deprecated asyncio.Task.cancel("message"). We realized we were too harsh, and have undeprecated it. - Change deprecate warning message in unittest from It is deprecated to return a value!=None to It is deprecated to return a value that is not None from a test case - Fixes AttributeError when subprocess.check_output() is used with argument input=None and either of the arguments encoding or errors are used. - Fix is_private properties in the ipaddress module. Previously non-private networks (0.0.0.0/0) would return True from this method; now they correctly return False. - Avoid spurious tracebacks from asyncio when default executor cleanup is delayed until after the event loop is closed (e.g. as the result of a keyboard interrupt). - Avoid a crash in the C version of asyncio.Future.remove_done_callback() when an evil argument is passed. - Remove tokenize.NL check from tabnanny. - Fix generation of the default name of tkinter.Checkbutton. Previously, checkbuttons in different parent widgets could have the same short name and share the same state if arguments “name” and “variable” are not specified. Now they are globally unique. - Update bundled libexpat to 2.4.9 - Fix race condition in asyncio where process_exited() called before the pipe_data_received() leading to inconsistent output. Patch by Kumar Aditya. - Fixed check in multiprocessing.resource_tracker that guarantees that the length of a write to a pipe is not greater than PIPE_BUF. - Corrected type annotation for dataclass attribute pstats.FunctionProfile.ncalls to be str. - Fix repr of Any subclasses. - Work around missing socket functions in socket’s __repr__. - In inspect, fix overeager replacement of “typing.” in formatting annotations. - Fix handling of bytes path-like objects in os.ismount(). - Fix handling compiler warnings (SyntaxWarning and DeprecationWarning) in codeop.compile_command() when checking for incomplete input. Previously it emitted warnings and raised a SyntaxError. Now it always returns None for incomplete input without emitting any warnings. - To avoid apparent memory leaks when asyncio.open_connection() raises, break reference cycles generated by local exception and future instances (which has exception instance as its member var). Patch by Dong Uk, Kang. - Fixed flickering of the turtle window when the tracer is turned off. Patch by Shin-myoung-serp. - Fix asyncio subprocess transport to kill process cleanly when process is blocked and avoid RuntimeError when loop is closed. Patch by Kumar Aditya. - Prevent error when activating venv in nested fish instances. - TarFile.next() now returns None when called on an empty tarfile. - Document the optional callback parameter of WeakMethod. Patch by Géry Ogam. - Restrict use of sockets instead of pipes for stdin of subprocesses created by asyncio to AIX platform only. - shutil.copytree() now applies the ignore_dangling_symlinks argument recursively. - Fix IndexError in argparse.ArgumentParser when a store_true action is given an explicit argument. - Document that calling variadic functions with ctypes requires special care on macOS/arm64 (and possibly other platforms). - Remove extra row - Clarified the conflicting advice given in the ast documentation about ast.literal_eval() being “safe” for use on untrusted input while at the same time warning that it can crash the process. The latter statement is true and is deemed unfixable without a large amount of work unsuitable for a bugfix. So we keep the warning and no longer claim that literal_eval is safe. - Restructured the documentation for the os.wait* family of functions, and improved the docs for os.waitid() with more explanation of the possible argument constants. - Skip test_normalization() of test_unicodedata if it fails to download NormalizationTest.txt file from pythontest.net. Patch by Victor Stinner. - Correct test_marsh on (32 bit) x86: test_deterministic sets was failing. - Optional big memory tests in test_sqlite3 now catch the correct sqlite.DataError exception type in case of too large strings and/or blobs passed. - Fix a bug in the typing tests where a test relying on CPython-specific implementation details was not decorated with @cpython_only and was not skipped on other implementations. - Add tests for star-unpacking with PEP 646, and some other miscellaneous PEP 646 tests. - Added explicit coverage of Py_Initialize (and hence Py_InitializeEx) back to the embedding tests (all other embedding tests migrated to Py_InitializeFromConfig in Python 3.11) - Some C API tests were moved into the new Lib/test/test_capi/ directory. - Fix -Wimplicit-int, -Wstrict-prototypes, and -Wimplicit-function-declaration compiler warnings in configure checks. - Fix a compilation issue with GCC 12 on macOS. - Fix -Wimplicit-int compiler warning in configure check for PTHREAD_SCOPE_SYSTEM. - Fix a possible fd leak in Programs/_freeze_module.c introduced in Python 3.11. - Fix build with PYTHON_FOR_REGEN=python3.8. - Specify the full path to the source location for make docclean (needed for cross-builds). - Don’t use vendored libmpdec headers if --with-system-libmpdec is passed to configure. Don’t use vendored libexpat headers if --with-system-expat is passed to !configure. - Fix the build process of clang compiler for _bootstrap_python if LTO optimization is applied. Patch by Matthias Görgens and Dong-hee Na. - wasm32-emscripten builds for browsers now include concurrent.futures for asyncio and unittest.mock. - wasm32-emscripten platform no longer builds resource module, getresuid(), getresgid(), and their setters. The APIs are stubs and not functional. - Updated pegen regeneration script on Windows to find and use Python 3.9 or higher. Prior to this, pegen regeneration already required 3.9 or higher, but the script may have used lower versions of Python. - Fix a bug in the previous bugfix that caused IDLE to not start when run with 3.10.8, 3.12.0a1, and at least Microsoft Python 3.10.2288.0 installed without the Lib/test package. 3.11.0 was never affected. - The wasm_build.py script now pre-builds Emscripten ports, checks for broken EMSDK versions, and warns about pkg-config env vars. - The new tool Tools/wasm/wasm_builder.py automates configure, compile, and test steps for building CPython on WebAssembly platforms. - Fix handling of module docstrings in Tools/i18n/pygettext.py. - PyBUF_* constants were marked as part of Limited API of Python 3.11+. These were available in 3.11.0 with Py_LIMITED_API defined for 3.11, and are necessary to use the buffer API. - Fix use-after-free in Py_SetPythonHome(NULL), Py_SetProgramName(NULL) and _Py_SetProgramFullPath(NULL) function calls. Issue reported by Benedikt Reinartz. Patch by Victor Stinner. - Py_InitializeEx now correctly calls PyConfig_Clear after initializing the interpreter (the omission didn’t cause a memory leak only because none of the dynamically allocated config fields are populated by the wrapper function) - Removed upstreamed patches: - 98437-sphinx.locale._-as-gettext-in-pyspecific.patch - CVE-2022-45061-DoS-by-IDNA-decode.patch ------------------------------------------------------------------- Wed Nov 9 18:31:23 UTC 2022 - Matej Cepl - Add CVE-2022-45061-DoS-by-IDNA-decode.patch to avoid CVE-2022-45061 (bsc#1205244) allowing DoS by IDNA decoding extremely long domain names. ------------------------------------------------------------------- Tue Oct 25 08:39:47 UTC 2022 - Matej Cepl - Update to 3.11.0 (overall changes from 3.10.*): - General changes - PEP 657 -- Include Fine-Grained Error Locations in Tracebacks - PEP 654 -- Exception Groups and except* - PEP 680 -- tomllib: Support for Parsing TOML in the Standard Library - gh-90908 -- Introduce task groups to asyncio - gh-34627 -- Atomic grouping ((?>...)) and possessive quantifiers (*+, ++, ?+, {m,n}+) are now supported in regular expressions. - The Faster CPython Project is already yielding some exciting results. Python 3.11 is up to 10-60% faster than Python 3.10. On average, we measured a 1.22x speedup on the standard benchmark suite. See Faster CPython for details. - Typing and typing language changes - PEP 673 -- Self Type - PEP 646 -- Variadic Generics - PEP 675 -- Arbitrary Literal String Type - PEP 655 -- Marking individual TypedDict items as required or potentially-missing - PEP 681 -- Data Class Transforms - (just changes from 3.11.0rc2): - Fix multiplying a list by an integer (list *= int): detect the integer overflow when the new allocated length is close to the maximum size. Issue reported by Jordan Limor. Patch by Victor Stinner. - On Linux the multiprocessing module returns to using filesystem backed unix domain sockets for communication with the forkserver process instead of the Linux abstract socket namespace. Only code that chooses to use the “forkserver” start method is affected. Abstract sockets have no permissions and could allow any user on the system in the same network namespace (often the whole system) to inject code into the multiprocessing forkserver process. This was a potential privilege escalation. Filesystem based socket permissions restrict this to the forkserver process user as was the default in Python 3.8 and earlier. This prevents Linux CVE-2022-42919. - Fix an issue where several frame objects could be backed by the same interpreter frame, possibly leading to corrupted memory and hard crashes of the interpreter. - Fix possible data corruption or crashes when accessing the f_back member of newly-created generator or coroutine frames. - Fix a crash occurring when PyEval_GetFrame() is called while the topmost Python frame is in a partially-initialized state. - Fix command line parsing: reject -X int_max_str_digits option with no value (invalid) when the PYTHONINTMAXSTRDIGITS environment variable is set to a valid limit. Patch by Victor Stinner. - Fix undefined behaviour in _testcapimodule.c. - When ValueError is raised if an integer is larger than the limit, mention the sys.set_int_max_str_digits() function in the error message. Patch by Victor Stinner. - Correctly raise SyntaxError on exception groups (PEP 654) on python versions prior to 3.11 - Document some places where an assignment expression needs parentheses. - Update the bundled copies of pip and setuptools to versions 22.3 and 65.5.0 respectively. - fix Flag to use boundary CONFORM - This restores previous Flag behavior of allowing flags with non-sequential values to be combined; e.g. - class Skip(Flag): TWO = 2 EIGHT = 8 - Skip.TWO | Skip.EIGHT -> - Fix ! in c domain ref target syntax via a conf.py patch, so it works as intended to disable ref target resolution. - Update tutorial introduction output to use 3.10+ SyntaxError invalid range. ------------------------------------------------------------------- Fri Oct 21 10:14:03 UTC 2022 - Matej Cepl - Add 98437-sphinx.locale._-as-gettext-in-pyspecific.patch to allow building of documentation with the latest Sphinx 5.3.0 (gh#python/cpython#98366). ------------------------------------------------------------------- Thu Sep 15 08:43:07 UTC 2022 - Matej Cepl - Update to 3.11.0rc2: - Converting between int and str in bases other than 2 (binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal) now raises a ValueError if the number of digits in string form is above a limit to avoid potential denial of service attacks due to the algorithmic complexity. This is a mitigation for CVE-2020-10735. This new limit can be configured or disabled by environment variable, command line flag, or sys APIs. See the integer string conversion length limitation documentation. The default limit is 4300 digits in string form. - Fix case of undefined behavior in ceval.c - Do not expose KeyWrapper in _functools. - Ensure that tracing, sys.setrace(), is turned on immediately. In pre-release versions of 3.11, some tracing events might have been lost when turning on tracing in a __del__ method or interrupt. - Fix use after free in trace refs build mode. Patch by Kumar Aditya. - When loading a file with invalid UTF-8 inside a multi-line string, a correct SyntaxError is emitted. - Make sure that incomplete frames do not show up in tracemalloc traces. - Remove two cases of undefined behavior, by adding NULL checks. - Fix possible NULL pointer dereference in _PyThread_CurrentFrames. Patch by Kumar Aditya. - Fix AttributeError missing name and obj attributes in object.__getattribute__(). Patch by Philip Georgi. - Loading a file with invalid UTF-8 will now report the broken character at the correct location. - Fixed a bug that caused _PyCode_GetExtra to return garbage for negative indexes. Patch by Pablo Galindo - Fix a deadlock in PyGILState_Ensure() when allocating new thread state. Patch by Kumar Aditya. - PyType_Ready() now initializes ht_cached_keys and performs additional checks to ensure that type objects are properly configured. This avoids crashes in 3rd party packages that don’t use regular API to create new types. - Skip over incomplete frames in PyThreadState_GetFrame(). - Fix format string in _PyPegen_raise_error_known_location that can lead to memory corruption on some 64bit systems. The function was building a tuple with i (int) instead of n (Py_ssize_t) for Py_ssize_t arguments. - Fix misleading contents of error message when converting an all-whitespace string to float. - ast.parse() will no longer parse function definitions with positional-only params when passed feature_version less than (3, 8). Patch by Shantanu Jain. - Fix incorrect error message in the io module. - Fix the faulthandler implementation of faulthandler.register(signal, chain=True) if the sigaction() function is not available: don’t call the previous signal handler if it’s NULL. Patch by Victor Stinner. - Correct conversion of numbers.Rational’s to float. - Fix TypeVarTuple.__typing_prepare_subst__. TypeError was not raised when using more than one TypeVarTuple, like [*T, *V] in type alias substitutions. - Fix asyncio.streams.StreamReaderProtocol to keep a strong reference to the created task, so that it’s not garbage collected - Fix a performance regression in logging TimedRotatingFileHandler. Only check for special files when the rollover time has passed. - Fix unused localName parameter in the Attr class in xml.dom.minidom. - Fix incorrect condition that causes sys.thread_info.name to be wrong on pthread platforms. - Remove an incompatible change from bpo-28080 that caused a regression that ignored the utf8 in ZipInfo.flag_bits. Patch by Pablo Galindo. - Fix asyncio.Runner to call asyncio.set_event_loop() only once to avoid calling attach_loop() multiple times on child watchers. Patch by Kumar Aditya. - Fix unittest.IsolatedAsyncioTestCase to set event loop before calling setup functions. Patch by Kumar Aditya. - When a task catches asyncio.CancelledError and raises some other error, the other error should generally not silently be suppressed. - Fail gracefully if EPERM or ENOSYS is raised when loading crypt methods.

Previously this event was only produced by sqlite3.connect() calls. Patch by Erlend E. Aasland. - bpo-43882: The presence of newline or tab characters in parts of a URL could allow some forms of attacks. - Following the controlling specification for URLs defined by WHATWG urllib.parse() now removes ASCII newlines and tabs from URLs, preventing such attacks. - bpo-43472: Ensures interpreter-level audit hooks receive the cpython.PyInterpreterState_New event when called through the _xxsubinterpreters module. - bpo-36384: ipaddress module no longer accepts any leading zeros in IPv4 address strings. Leading zeros are ambiguous and interpreted as octal notation by some libraries. For example the legacy function socket.inet_aton() treats leading zeros as octal notatation. glibc implementation of modern inet_pton() does not accept any leading zeros. For a while the ipaddress module used to accept ambiguous leading zeros. - 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. - bpo-42800: Audit hooks are now fired for frame.f_code, traceback.tb_frame, and generator code/frame attribute access. * 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-41735: Fix thread locks in zlib module may go wrong in rare case. Patch by Ma Lin. - bpo-36470: Fix dataclasses with InitVars and replace(). Patch by Claudiu Popa. - 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-43755: Update documentation to reflect that unparenthesized lambda expressions can no longer be the expression part in an if clause in comprehensions and generator expressions since Python 3.9. - 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-43961: Fix test_logging.test_namer_rotator_inheritance() on Windows: use os.replace() rather than os.rename(). Patch by Victor Stinner. - 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. - Refreshed patches: - bpo-31046_ensurepip_honours_prefix.patch - python-3.3.0b1-fix_date_time_compiler.patch - Add vendorized files from bluez-devel to enable building support for Bluetooth. ------------------------------------------------------------------- Sun May 2 09:20:06 UTC 2021 - Ben Greiner - Make sure to close the import_failed.map file after the exception has been raised in order to avoid ResourceWarnings when the failing import is part of a try...except block. ------------------------------------------------------------------- Wed Apr 28 16:39:54 UTC 2021 - Matej Cepl - Update to 3.9.4: - bpo#43710: Reverted the fix for https://bugs.python.org/issue42500 as it changed the PyThreadState struct size and broke the 3.9.x ABI in the 3.9.3 release (visible on 32-bit platforms using binaries compiled using an earlier version of Python 3.9.x headers). - 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#42988 (bsc#1183374) CVE-2021-3426: Remove the getfile feature of the pydoc module which could be abused to read arbitrary files on the disk (directory traversal vulnerability). Moreover, even source code of Python modules can contain sensitive data like passwords. Vulnerability reported by David Schwörer. - bpo#43285: ftplib no longer trusts the IP address value returned from the server in response to the PASV command by default. This prevents a malicious FTP server from using the response to probe IPv4 address and port combinations on the client network. Code that requires the former vulnerable behavior may set a trust_server_pasv_ipv4_address attribute on their ftplib.FTP instances to True to re-enable it. - bpo#43439: Add audit hooks for gc.get_objects(), gc.get_referrers() and gc.get_referents(). Patch by Pablo Galindo. - bpo#43660: Fix crash that happens when replacing sys.stderr with a callable that can remove the object while an exception is being printed. Patch by Pablo Galindo. - bpo#43555: Report the column offset for SyntaxError for invalid line continuation characters. Patch by Pablo Galindo. - bpo#43517: Fix misdetection of circular imports when using from pkg.mod import attr, which caused false positives in non-trivial multi-threaded code. - bpo#35883: Python no longer fails at startup with a fatal error if a command line argument contains an invalid Unicode character. The Py_DecodeLocale() function now escapes byte sequences which would be decoded as Unicode characters outside the [U+0000; U+10ffff] range. - bpo#43406: Fix a possible race condition where PyErr_CheckSignals tries to execute a non-Python signal handler. - bpo#42500: Improve handling of exceptions near recursion limit. Converts a number of Fatal Errors in RecursionErrors. - bpo#43433: xmlrpc.client.ServerProxy no longer ignores query and fragment in the URL of the server. - bpo#35930: Raising an exception raised in a “future” instance will create reference cycles. - bpo#43577: Fix deadlock when using ssl.SSLContext debug callback with ssl.SSLContext.sni_callback(). - bpo#43521: ast.unparse can now render NaNs and empty sets. - bpo#43423: subprocess.communicate() no longer raises an IndexError when there is an empty stdout or stderr IO buffer during a timeout on Windows. - bpo#27820: Fixed long-standing bug of smtplib.SMTP where doing AUTH LOGIN with initial_response_ok=False will fail. The cause is that SMTP.auth_login _always_ returns a password if provided with a challenge string, thus non-compliant with the standard for AUTH LOGIN. Also fixes bug with the test for smtpd. - bpo#43332: Improves the networking efficiency of http.client when using a proxy via set_tunnel(). Fewer small send calls are made during connection setup. - bpo#43399: Fix ElementTree.extend not working on iterators when using the Python implementation - bpo#43316: The python -m gzip command line application now properly fails when detecting an unsupported extension. It exits with a non-zero exit code and prints an error message to stderr. - bpo#43260: Fix TextIOWrapper can not flush internal buffer forever after very large text is written. - bpo#42782: Fail fast in shutil.move() to avoid creating destination directories on failure. - bpo#37193: Fixed memory leak in socketserver.ThreadingMixIn introduced in Python 3.7. - bpo#43199: Answer “Why is there no goto?” in the Design and History FAQ. - bpo#43407: Clarified that a result from time.monotonic(), time.perf_counter(), time.process_time(), or time.thread_time() can be compared with the result from any following call to the same function - not just the next immediate call. - bpo#27646: Clarify that ‘yield from ’ works with any iterable, not just iterators. - bpo#36346: Update some deprecated unicode APIs which are documented as “will be removed in 4.0” to “3.12”. See PEP 623 for detail. - bpo#37945: Fix test_getsetlocale_issue1813() of test_locale: skip the test if setlocale() fails. Patch by Victor Stinner. - bpo#41561: Add workaround for Ubuntu’s custom OpenSSL security level policy. - bpo#43288: Fix test_importlib to correctly skip Unicode file tests if the fileystem does not support them. - bpo#43617: Improve configure.ac: Check for presence of autoconf-archive package and remove our copies of M4 macros. - bpo#42225: Document that IDLE can fail on Unix either from misconfigured IP masquerage rules or failure displaying complex colored (non-ascii) characters. - bpo#43283: Document why printing to IDLE’s Shell is often slower than printing to a system terminal and that it can be made faster by pre-formatting a single string before printing. ------------------------------------------------------------------- Fri Feb 19 16:58:38 UTC 2021 - Matej Cepl - Update to 3.9.2: - bpo#42938 (bsc#1181126): Avoid static buffers when computing the repr of ctypes.c_double and ctypes.c_longdouble values. This issue was assigned CVE-2021-3177. - bpo#42967 (bsc#1182379): Fix web cache poisoning vulnerability by defaulting the query args separator to &, and allowing the user to choose a custom separator. This issue was assigned CVE-2021-23336. - Upstreamed patches were removed: - CVE-2021-3177-buf_ovrfl_PyCArg_repr.patch - bsc1167501-invalid-alignment.patch - skip_random_failing_tests.patch - CVE-2019-5010-null-defer-x509-cert-DOS.patch ------------------------------------------------------------------- Tue Feb 9 01:37:59 UTC 2021 - Steve Kowalik - Add Obsoletes for python3-base when primary interpreter is set to properly replace it during upgrades. (bsc#1181324) ------------------------------------------------------------------- Mon Feb 8 22:02:03 UTC 2021 - Matej Cepl - Update to 3.9.1: Security bugs: - Prevented potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format. - The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities. This should not affect users as entity declarations are not used in regular plist files. - Add volatile to the accumulator variable in hmac.compare_digest, making constant-time-defeating optimizations less likely. Core and Builtins - Allow assignment expressions in set literals and set comprehensions as per PEP 572. Patch by Pablo Galindo. - Fix a regression introduced by the new parser, where an unparenthesized walrus operator was not allowed within generator expressions. - types.GenericAlias objects can now be the targets of weakrefs. - Fixed a bug in the PEG parser that was causing crashes in debug mode. Now errors are checked in left-recursive rules to avoid cases where such errors do not get handled in time and appear as long-distance crashes in other places. - Fixed a possible crash in the PEG parser when checking for the ‘!=’ token in the barry_as_flufl rule. Patch by Pablo Galindo. - Fix handling of errors during creation of PyFunctionObject, which resulted in operations on uninitialized memory. Patch by Yonatan Goldschmidt. - Fix a bug in the parser, where a curly brace following a primary didn’t fail immediately. This led to invalid expressions like a {b} to throw a SyntaxError with a wrong offset, or invalid expressions ending with a curly brace like a { to not fail immediately in the REPL. - Fix possible buffer overflow in the new parser when checking for continuation lines. Patch by Pablo Galindo. - Run the parser two times. On the first run, disable all the rules that only generate better error messages to gain performance. If there’s a parse failure, run the parser a second time with those enabled. - Document the default implementation of object.__eq__. - Fix peephole optimizer misoptimize conditional jump + JUMP_IF_NOT_EXC_MATCH pair. - The garbage collector now tracks all user-defined classes. Patch by Brandt Bucher. - Fixed potential issues with removing not completely initialized module from sys.modules when import fails. - Star-unpacking is now allowed for with item’s targets in the PEG parser. - Fixed stack overflow in issubclass() and isinstance() when getting the __bases__ attribute leads to infinite recursion. - When loading a native module and a load failure occurs, prevent a possible UnicodeDecodeError when not running in a UTF-8 locale by decoding the load error message using the current locale’s encoding. - Correctly count control blocks in ‘except’ in compiler. Ensures that a syntax error, rather a fatal error, occurs for deeply nested, named exception handlers. Library - types.GenericAlias will now raise a TypeError when attempting to initialize with a keyword argument. Previously, this would cause the interpreter to crash if the interpreter was compiled with debug symbols. This does not affect interpreters compiled for release. Patch by Ken Jin. - CGIHTTPRequestHandler.run_cgi() HTTP_ACCEPT improperly parsed. Replace the special purpose getallmatchingheaders with generic get_all method and add relevant tests. - inspect.findsource() now raises OSError instead of IndexError when co_lineno of a code object is greater than the file length. This can happen, for example, when a file is edited after it was imported. PR by Irit Katriel. - Fix handling of trailing comments by inspect.getsource(). - ChainMap.__iter__ no longer calls __getitem__ on underlying maps - TracebackException no longer holds a reference to the exception’s traceback object. Consequently, instances of TracebackException for equivalent but non-equal exceptions now compare as equal. - We fixed an issue in pickle.whichmodule in which importing multiprocessing could change the how pickle identifies which module an object belongs to, potentially breaking the unpickling of those objects. - Clarify the error message for asyncio.IncompleteReadError when expected is None. - Extracting a symlink from a tarball should succeed and overwrite the symlink if it already exists. The fix is to remove the existing file or symlink before extraction. Based on patch by Chris AtLee, Jeffrey Kintscher, and Senthil Kumaran. - Fixed tkinter.ttk.Style.map(). The function accepts now the representation of the default state as empty sequence (as returned by Style.map()). The structure of the result is now the same on all platform and does not depend on the value of wantobjects. - Fix various issues with typing.Literal parameter handling (flatten, deduplicate, use type to cache key). Patch provided by Yurii Karabas. - Fix the threading.Thread class at fork: do nothing if the thread is already stopped (ex: fork called at Python exit). Previously, an error was logged in the child process. - The onerror callback from shutil.rmtree now receives correct function when os.open fails. - Fix os.sendfile() on illumos. - Fixed writing binary Plist files larger than 4 GiB. - The repr() of typing types containing Generic Alias Types previously did not show the parameterized types in the GenericAlias. They have now been changed to do so. - webbrowser: Ignore NotADirectoryError when calling xdg-settings. - binhex.binhex() consisently writes macOS 9 line endings. - Fix a stack overflow error for asyncio Task or Future repr(). - The overflow occurs under some circumstances when a Task or Future recursively returns itself. - Fix memory leak in subprocess.Popen() in case an uid (gid) specified in user (group, extra_groups) overflows uid_t (gid_t). - Improve asyncio.wait function to create the futures set just one time. - InvalidFileException and RecursionError are now the only errors caused by loading malformed binary Plist file (previously ValueError and TypeError could be raised in some specific cases). - Pickling heap types implemented in C with protocols 0 and 1 raises now an error instead of producing incorrect data. - plistlib: fix parsing XML plists with hexadecimal integer values - Fix an incorrectly formatted error from _codecs.charmap_decode() when called with a mapped value outside the range of valid Unicode code points. PR by Max Bernstein. - Fix pickling pure Python datetime.time subclasses. Patch by Dean Inwood. - Fixed a bug that was causing ctypes.util.find_library() to return None when triying to locate a library in an environment when gcc>=9 is available and ldconfig is not. Patch by Pablo Galindo - C14N 2.0 serialisation in xml.etree.ElementTree failed for unprefixed attributes when a default namespace was defined. - Fix a bug in the symtable module that was causing module-scope global variables to not be reported as both local and global. Patch by Pablo Galindo. - str() for the type attribute of the tkinter.Event object always returns now the numeric code returned by Tk instead of the name of the event type. - fix tkinter.EventType Enum so all members are strings, and none are tuples - Fix SQLite3 segfault when backing up closed database. Patch contributed by Peter David McCormick. - Fix the tarfile module to write only basename of TAR file to GZIP compression header. - Allow ctypes.wintypes to be imported on non-Windows systems. - shutil.which() now ignores empty entries in PATHEXT instead of treating them as a match. - Fix time-of-check/time-of-action issue in subprocess.Popen.send_signal. - Fix --outfile for cProfile / profile not writing the output file in the original directory when the program being profiled changes the working directory.

Build - Fix a race condition in “make regen-all” when make -jN option is used to run jobs in parallel. The clinic.py script now only use atomic write to write files. Moveover, generated files are now left unchanged if the content does not change, to not change the file modification time. - Update Py_UNREACHABLE to use __builtin_unreachable() if only the compiler is able to use it. Patch by Dong-hee Na. - Addressed three compiler warnings found by undefined behavior sanitizer (ubsan).
