* gh-106168: PyTuple_SET_ITEM() now checks the index (#106164)Victor Stinner2023-06-281-0/+6
| | | | | | | | | | | | | PyTuple_SET_ITEM() and PyList_SET_ITEM() now check the index argument with an assertion if Python is built in debug mode or is built with assertions. * list_extend() and _PyList_AppendTakeRef() now set the list size before calling PyList_SET_ITEM(). * PyStructSequence_GetItem() and PyStructSequence_SetItem() now check the index argument: must be lesser than REAL_SIZE(op). * PyStructSequence_GET_ITEM() and PyStructSequence_SET_ITEM() are now aliases to PyStructSequence_GetItem() and PyStructSequence_SetItem().
* Revert "GH-96145: Add AttrDict to JSON module for use with object_hook ↵Łukasz Langa2023-06-261-8/+0
| | | | | (#96146)" (#105948) This reverts commit 1f0eafa844bf5a380603d55e8d4b42d8c2a3439d.
* GH-105793: Add follow_symlinks argument to `pathlib.Path.is_dir()` and ↵Barney Gale2023-06-261-3/+4
| | | | | | | `is_file()` (GH-105794) Brings `pathlib.Path.is_dir()` and `in line with `os.DirEntry.is_dir()`, which will be important for implementing generic path walking and globbing. Likewise `is_file()`.
* gh-105927: Deprecate PyWeakref_GetObject() function (#106006)Victor Stinner2023-06-261-1/+9
| | | Deprecate PyWeakref_GetObject() and PyWeakref_GET_OBJECT() functions.
* gh-106084: Remove old PyObject call aliases (#106085)Victor Stinner2023-06-261-0/+14
| | | | | | | | | | | | | | Remove old aliases which were kept backwards compatibility with Python 3.8: * _PyObject_CallMethodNoArgs() * _PyObject_CallMethodOneArg() * _PyObject_CallOneArg() * _PyObject_FastCallDict() * _PyObject_Vectorcall() * _PyObject_VectorcallMethod() * _PyVectorcall_Function() Update code which used these aliases to use new names.
* GH-89812: Add `pathlib.UnsupportedOperation` (GH-105926)Barney Gale2023-06-221-0/+4
| | | | | | | This new exception type is raised instead of `NotImplementedError` when a path operation is not supported. It can be raised from `Path.readlink()`, `symlink_to()`, `hardlink_to()`, `owner()` and `group()`. In a future version of pathlib, it will be raised by `AbstractPath` for these methods and others, such as `AbstractPath.mkdir()` and `unlink()`.
* gh-104212: Explain how to port imp.load_source() (#105978)Victor Stinner2023-06-211-1/+15
| | | | Explain how to port removed imp.load_source() to importlib in What's New in Python 3.12.

* gh-105875: Require SQLite 3.15.2 or newer (#105876)Erlend E. Aasland2023-06-181-0/+3
| | | SQLite 3.15.2 was released 2016-11-28.
* gh-105570: Deprecate unusual ways of creating empty TypedDicts (#105780)Alex Waygood2023-06-141-6/+9
| | | Deprecate two methods of creating typing.TypedDict classes with 0 fields using the functional syntax: `TD = TypedDict("TD")` and `TD = TypedDict("TD", None)`. Both will be disallowed in Python 3.15. To create a TypedDict class with 0 fields, either use `class TD(TypedDict): pass` or `TD = TypedDict("TD", {})`.
* gh-105566: Deprecate unusual ways of creating `typing.NamedTuple` classes ↵Alex Waygood2023-06-141-0/+11
| | | | | | | (#105609) Deprecate creating a typing.NamedTuple class using keyword arguments to denote the fields (`NT = NamedTuple("NT", x=int, y=str)`). This will be disallowed in Python 3.15. Use the class-based syntax or the functional syntax instead. Two methods of creating `NamedTuple` classes with 0 fields using the functional syntax are also deprecated, and will be disallowed in Python 3.15: `NT = NamedTuple("NT")` and `NT = NamedTuple("NT", None)`. To create a `NamedTuple` class with 0 fields, either use `class NT(NamedTuple): pass` or `NT = NamedTuple("NT", [])`.

* gh-102304: Fix Py_INCREF() stable ABI in debug mode (#104763)Victor Stinner2023-06-061-0/+9
| | | | | | | | | | | When Python is built in debug mode (if the Py_REF_DEBUG macro is defined), the Py_INCREF() and Py_DECREF() function are now always implemented as opaque functions to avoid leaking implementation details like the "_Py_RefTotal" variable or the _Py_DecRefTotal_DO_NOT_USE_THIS() function. * Remove _Py_IncRefTotal_DO_NOT_USE_THIS() and _Py_DecRefTotal_DO_NOT_USE_THIS() from the stable ABI. * Remove _Py_NegativeRefcount() from limited C API.
