Move types to the ctypes_state structure:

  • PyCArray_Type
  • PyCData_Type
  • PyCFuncPtr_Type
  • PyCPointer_Type
  • Simple_Type

The following macros get an additional state parameter:

  • ArrayObject_Check()
  • CDataObject_Check()
  • CDataObject_CheckExact()
  • PointerObject_Check()
  • PyCFuncPtrObject_Check()

The following function gets an additional state parameter:

  • _PyCData_set()

Move types to the ctypes_state structure:* PyCArray_Type* PyCData_Type* PyCFuncPtr_Type* PyCPointer_Type* Simple_TypeThe following macros get an additional state parameter:* ArrayObject_Check()* CDataObject_Check()* CDataObject_CheckExact()* PointerObject_Check()* PyCFuncPtrObject_Check()The following function gets an additional state parameter:* _PyCData_set()Co-Authored-By: neonene <53406459+neonene@users.noreply.github.com>

This change only prepares the code to convert static types to heap types. It doesn't change the behavior.

It only moves references to types from global variables to the_ctypesstate and pass the state to macros and functions using it.

To keep this change as small as possible, I didn't change the following macros to add a newstate parameter.

#define PyCSimpleTypeObject_CheckExact(v)       Py_IS_TYPE(v, GLOBAL_STATE()->PyCSimpleType_Type)#define PyCSimpleTypeObject_Check(v)    PyObject_TypeCheck(v, GLOBAL_STATE()->PyCSimpleType_Type)#define PyCArrayTypeObject_Check(v)     PyObject_TypeCheck(v, GLOBAL_STATE()->PyCArrayType_Type)#define PyCPointerTypeObject_Check(v)   PyObject_TypeCheck(v, GLOBAL_STATE()->PyCPointerType_Type)#define PyCFuncPtrTypeObject_Check(v)   PyObject_TypeCheck(v, GLOBAL_STATE()->PyCFuncPtrType_Type)#define PyCStructTypeObject_Check(v)    PyObject_TypeCheck(v, GLOBAL_STATE()->PyCStructType_Type)

These macros can be changed afterwards.

PR#113857, which expects fewer follow-up PRs, can be closed after this is landed.

I merged#113857 instead.
