Add a new Py_TPFLAGS_DISALLOW_INSTANTIATION type flag to disallow creating type instances: set tp_new to NULL and don't create the "__new__" key in the type dictionary. The flag is set automatically on static types if tp_base is NULL or &PyBaseObject_Type and tp_new is NULL. Use the flag on the following types: * _curses.ncurses_version type * _curses_panel.panel * _tkinter.Tcl_Obj * _tkinter.tkapp * _tkinter.tktimertoken * _xxsubinterpretersmodule.ChannelID * sys.flags type * sys.getwindowsversion() type * sys.version_info type Update MyStr example in the C API documentation to use Py_TPFLAGS_DISALLOW_INSTANTIATION. Add _PyStructSequence_InitType() function to create a structseq type with the Py_TPFLAGS_DISALLOW_INSTANTIATION flag set. type_new() calls _PyType_CheckConsistency() at exit. |
