Currently, 33 types explicitly set the Py_TPFLAGS_DISALLOW_INSTANTIATION flag: * PyStdPrinter_Type * _curses.ncurses_version type * _curses_panel.panel * _dbm.dbm * _gdbm.gdbm * _hashlib.HASH * _hashlib.HASHXOF * _hashlib.HMAC * _multibytecodec.MultibyteCodec * _sre..SRE_Scanner * _thread._localdummy * _thread.lock * _tkinter.Tcl_Obj * _tkinter.tkapp * _tkinter.tktimertoken * _winapi.Overlapped * _xxsubinterpretersmodule.ChannelID * array.arrayiterator * functools.KeyWrapper * functools._lru_list_elem * os.DirEntry * os.ScandirIterator * pyexpat.xmlparser * re.Match * re.Pattern * select.poll * sys.flags type * sys.getwindowsversion() type * sys.version_info type * unicodedata.UCD * zlib.Compress * zlib.Decompress * _xxsubinterpreters.ChannelID --- Static types with tp_base=NULL (or tp_base=&PyBaseObject_Type) and tp_new=NULL get Py_TPFLAGS_DISALLOW_INSTANTIATION flag automatically. Example of 70 static types which gets this flag automatically: * CArgObject * EncodingMap * Generic * GenericAlias * PyCapsule * TaskStepMethWrapper * Token.MISSING * _RunningLoopHolder * _asyncio.FutureIter * _ctypes.CThunkObject * _ctypes.StructParam_Type * _ctypes._CData * _elementtree._element_iterator * _io._BytesIOBuffer * _pickle.Pdata * _pickle.PicklerMemoProxy * _pickle.UnpicklerMemoProxy * _xxsubinterpreters.ChannelID * anext_awaitable * async_generator * async_generator_asend * async_generator_athrow * async_generator_wrapped_value * builtin_function_or_method * bytearray_iterator * bytes_iterator * callable_iterator * classmethod_descriptor * coroutine * coroutine_wrapper * decimal.ContextManager * dict_itemiterator * dict_items * dict_keyiterator * dict_keys * dict_reverseitemiterator * dict_reversekeyiterator * dict_reversevalueiterator * dict_valueiterator * dict_values * fieldnameiterator * formatteriterator * frame * generator * getset_descriptor * hamt_array_node * hamt_bitmap_node * hamt_collision_node * items * iterator * keys * list_iterator * list_reverseiterator * longrange_iterator * managedbuffer * member_descriptor * method-wrapper * method_descriptor * moduledef * odict_iterator * range_iterator * set_iterator * str_iterator * symtable entry * tuple_iterator * types.Union * values * weakcallableproxy * weakproxy * wrapper_descriptor ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43916> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
