Ubuntu 22.04 ships with mpdecimal 2.5.1, installable using 'apt install libmpdec-dev'.
It is set by compiler with the line number of the first line of the class definition.
Documentation wording taken from the withdrawn PEP 558 (which had switched to the Python level semantics proposed in PEP 667 prior to its withdrawal).
#118624) Properly implement the `sq_contains` slot for frame locals proxy containment checks.
Only include underscored names in name suggestions for AttributeError and ImportError if the original name was underscored.
…GH-118273) * Add PhotoImage.read() to read an image from a file. * Add PhotoImage.data() to get the image data. * Add background and grayscale parameters to PhotoImage.write().
…18291) This is an experimental feature, for internal use. Setting tkinter._debug = True before creating the root window enables printing every executed Tcl command (or a Tcl command equivalent to the used Tcl C API). This will help to convert a Tkinter example into Tcl script to check whether the issue is caused by Tkinter or exists in the underlying Tcl/Tk library.
…GH-117906) * GH-117714: replace athrow().close() and asend().close() stubs with implimentations * test athrow().close() and asend().close() raises RuntimeError * 📜🤖 Added by blurb_it. * Update Objects/genobject.c Co-authored-by: Petr Viktorin <encukou@gmail.com> --------- Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com> Co-authored-by: Petr Viktorin <encukou@gmail.com>
…e face of concurrent mutators (#118454) Add _PyType_LookupRef and use incref before setting attribute on type Makes setting an attribute on a class and signaling type modified atomic Avoid adding re-entrancy exposing the type cache in an inconsistent state by decrefing after type is updated

…#118808) Some embedders and extensions include parts of the internal API. The pycore_mimalloc.h file is transitively include by a number of other internal headers. This avoids include errors for code that was already including those headers.
Avoid immortalizing objects in tests that verify garbage collection of classes or modules. This fixes test_ordered_dict and test_struct.
Using `race:` filters out warnings if the function appears anywhere in the stack trace. This can hide a lot of unrelated warnings, especially for a function like `_PyEval_EvalFrameDefault`, which is somewhere on the stack more often than not. Change all free-threaded suppressions to `race_top:`, which only matches the top frame, and add any new suppressions this exposes.

* shm_unlink() parameter becomes positional-only. * shm_open() first parameter (path) becomes positional-only, the two following parameters remain positional-or-keyword.
Move types to the datetime_state structure of the _datetime extension.
_PyWeakref_ClearRef was previously exposed in the public C-API, although it begins with an underscore and is not documented. It's used by a few C-API extensions. There is currently no alternative public API that can replace its use. _PyWeakref_ClearWeakRefsExceptCallbacks is the only thread-safe way to use _PyWeakref_ClearRef in the free-threaded build. This exposes the C symbol, but does not make the API public.
…118865) Use relaxed loads/stores when reading/writing to this field.
`_Py_qsbr_unregister` is called when the PyThreadState is already detached, so the access to `tstate->qsbr` isn't safe without locking the shared mutex. Grab the `struct _qsbr_shared` from the interpreter instead.
…w` in `secrets.rst` (GH-118098) Correct the argument names for `secrets.choice` and `secrets.randbelow` in `secrets.rst`.
…ents (#118780) Remove support for supplying additional positional arguments to `PurePath.relative_to()` and `is_relative_to()`. This has been deprecated since Python 3.12.
Unfortunately, released versions of typing_extensions monkeypatch this function without the extra parameter, which makes it so things break badly if current main is used with typing_extensions. Fortunately, the monkeypatching is not needed on Python 3.13, because CPython now implements PEP 696. By renaming the function, we prevent the monkeypatch from breaking typing.py internals. We keep the old name (raising a DeprecationWarning) to help other external users who call it.
* BaseException_vectorcall() now creates a tuple from 'args' array. * Creation an exception using BaseException_vectorcall() is now a single function call, rather than having to call BaseException_new() and then BaseException_init(). Calling BaseException_init() is inefficient since it overrides the 'args' attribute. * _PyErr_SetKeyError() now uses PyObject_CallOneArg() to create the KeyError instance to use BaseException_vectorcall().
…18864) The free-threaded build currently immortalizes some objects once the first thread is started. This can lead to test failures depending on the order in which tests are run. This PR addresses those failures by suppressing immortalization or skipping the affected tests.
