* gh-106320: Remove private _PySys functions (#108452)Victor Stinner2023-08-241-0/+2
| | | | | | | | | | Move private functions to the internal C API (pycore_sysmodule.h): * _PySys_GetAttr() * _PySys_GetSizeOf() No longer export most of these functions. Fix also a typo in Include/cpython/optimizer.h: add a missing space.

* gh-99845: Use size_t type in __sizeof__() methods (#99846)Victor Stinner2022-11-301-6/+4
| | | | | | | | The implementation of __sizeof__() methods using _PyObject_SIZE() now use an unsigned type (size_t) to compute the size, rather than a signed type (Py_ssize_t). Cast explicitly signed (Py_ssize_t) values to unsigned type (Py_ssize_t).
* gh-99300: Use Py_NewRef() in Modules/ directory (#99467)Victor Stinner2022-11-141-12/+6

* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
