Message 411998 - Python tracker (original) (raw)

Changes already done:

• Macros converted to regular functions:

  • PyObject_GET_WEAKREFS_LISTPTR(); add internal inline _PyObject_GET_WEAKREFS_LISTPTR()
  • PyType_SUPPORTS_WEAKREFS(); add internal inline _PyType_SUPPORTS_WEAKREFS()
  • PyObject_CheckBuffer(); no fast internal API
  • PyObject_IS_GC(); no fast internal API
  • PyDescr_IsData(); no fast internal API

• Always implemented as a function, remove macro optimization in the non-limited API:

  • PyIter_Check(); no fast internal API
  • PyIndex_Check(); add internal inline _PyIndex_Check()
  • PyExceptionClass_Name(); no fast internal API

• Py_TRASHCAN_BEGIN() macro now calls _PyTrash_cond() function: no longer read directly tp_dealloc member

• PyObject_NEW() macro becomes an alias to PyObject_New()

• Remove PyHeapType_GET_MEMBERS() (move it to the internal C API)

PyType_HasFeature() is left unchanged since the change caused performance issue on macOS, whereas Python is not built with LTO.
