* gh-106320: Create pycore_modsupport.h header file (#106355)Victor Stinner2023-07-031-2/+3
| | | | | | | | | | Remove the following functions from the C API, move them to the internal C API: add a new pycore_modsupport.h internal header file: * PyModule_CreateInitialized() * _PyArg_NoKwnames() * _Py_VaBuildStack() No longer export these functions.

* gh-82012: Deprecate bitwise inversion (~) of bool (#103487)Tim Hoffmann2023-05-031-1/+17
| | | | | | | | | | | | | | The bitwise inversion operator on bool returns the bitwise inversion of the underlying int value; i.e. `~True == -2` such that `bool(~True) == True`. It's a common pitfall that users mistake `~` as negation operator and actually want `not`. Supporting `~` is an artifact of bool inheriting from int. Since there is no real use-case for the current behavior, let's deprecate `~` on bool and later raise an error. This removes a potential source errors for users.

* gh-84436: Implement Immortal Objects (gh-19474)Eddie Elizondo2023-04-221-3/+7
| | | | | | | | | This is the implementation of PEP683 Motivation: The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime. Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.
* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-2/+7
| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().
* gh-101266: Fix __sizeof__ for subclasses of int (#101394)Mark Dickinson2023-02-051-2/+4
| | | | | | | Fix the behaviour of the `__sizeof__` method (and hence the results returned by `sys.getsizeof`) for subclasses of `int`. Previously, `int` subclasses gave identical results to the `int` base class, ignoring the presence of the instance dictionary. <!-- gh-issue-number: gh-101266 --> * Issue: gh-101266 <!-- /gh-issue-number -->

The tests that are expected to break are: test_codecencodings_cn test_codecencodings_hk test_codecencodings_jp test_codecencodings_kr test_codecencodings_tw test_codecs test_multibytecodec This merge fixes an actual test failure (test_weakref) in this branch, though, so I believe merging is the right thing to do anyway.

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.
