New submission from Serhiy Storchaka: Proposed patch excludes the private API from the stable API. This includes:
_Py_Identifier-related API (other _Py_Identifier-related functions are already excluded): struct _Py_Identifier; #define _Py_static_string_init(value) #define _Py_static_string(varname, value) #define _Py_IDENTIFIER(varname) PyAPI_FUNC(PyObject*) _PyUnicode_FromId(_Py_Identifier*); PyAPI_FUNC(PyObject *) _PyObject_GetAttrId(PyObject *, struct _Py_Identifier *); PyAPI_FUNC(int) _PyObject_SetAttrId(PyObject *, struct _Py_Identifier *, PyObject *); PyAPI_FUNC(int) _PyObject_HasAttrId(PyObject *, struct _Py_Identifier *); PyAPI_FUNC(PyObject *) _PyObject_CallMethodId(PyObject *o, _Py_Identifier *method, const char *format, ...); PyAPI_FUNC(PyObject *) _PyObject_CallMethodId_SizeT(PyObject *o, _Py_Identifier *name, const char *format, ...); PyAPI_FUNC(PyObject *) _PyObject_CallMethodIdObjArgs(PyObject *o, struct _Py_Identifier *method, ...); PyAPI_FUNC(PyObject *) _PyDict_GetItemIdWithError(PyObject *dp, struct _Py_Identifier *key); PyAPI_FUNC(PyObject *) _PyDict_GetItemId(PyObject *dp, struct _Py_Identifier *key); PyAPI_FUNC(int) _PyDict_SetItemId(PyObject *dp, struct _Py_Identifier *key, PyObject *item); PyAPI_FUNC(PyObject *) _PySys_GetObjectId(_Py_Identifier *key); File helpers that hides OS-specific details and handle EINTR: PyAPI_FUNC(PyObject *) _Py_device_encoding(int); PyAPI_FUNC(FILE *) _Py_wfopen(const wchar_t *path, const wchar_t *mode); PyAPI_FUNC(FILE*) _Py_fopen(const char *pathname, const char *mode); PyAPI_FUNC(FILE*) _Py_fopen_obj(PyObject *path, const char *mode); PyAPI_FUNC(Py_ssize_t) _Py_read(int fd, void *buf, size_t count); PyAPI_FUNC(Py_ssize_t) _Py_write(int fd, const void *buf, size_t count); PyAPI_FUNC(Py_ssize_t) _Py_write_noraise(int fd, const void *buf, size_t count); PyAPI_FUNC(int) _Py_wreadlink(const wchar_t *path, wchar_t *buf, size_t bufsiz); PyAPI_FUNC(wchar_t*) _Py_wrealpath(const wchar_t *path, wchar_t *resolved_path, size_t resolved_path_size); PyAPI_FUNC(wchar_t*) _Py_wgetcwd(wchar_t *buf, size_t size); Other OS functions: PyAPI_FUNC(int) _PyOS_IsMainThread(void); PyAPI_FUNC(void*) _PyOS_SigintEvent(void); PyAPI_FUNC(int) _PyOS_GetOpt(int argc, wchar_t **argv, wchar_t *optstring); PyAPI_FUNC(int) _PyOS_URandom(void *buffer, Py_ssize_t size); Old helpers kept for binary compatibility of extensions built before 3.2.4: PyAPI_FUNC(void) _PyTrash_deposit_object(PyObject*); PyAPI_FUNC(void) _PyTrash_destroy_chain(void); PyAPI_DATA(int) _PyTrash_delete_nesting; PyAPI_DATA(PyObject *) _PyTrash_delete_later; And other functions and data: PyAPI_DATA(PyTypeObject) _PyNone_Type; PyAPI_DATA(PyTypeObject) _PyNotImplemented_Type; PyAPI_DATA(PyTypeObject) _PyMethodWrapper_Type; PyAPI_DATA(int) _Py_SwappedOp[]; PyAPI_FUNC(Py_ssize_t) _Py_GetAllocatedBlocks(void); PyAPI_FUNC(PyObject *) _PyObject_GC_Malloc(size_t size); PyAPI_FUNC(PyObject *) _PyObject_GC_Calloc(size_t size); PyAPI_FUNC(int) _PyObject_IsAbstract(PyObject *); PyAPI_FUNC(PyObject*) _Py_strhex(const char* argbuf, const Py_ssize_t arglen); PyAPI_FUNC(PyObject*) _Py_strhex_bytes(const char* argbuf, const Py_ssize_t arglen); PyAPI_FUNC(void) _Py_add_one_to_index_F(int nd, Py_ssize_t *index, const Py_ssize_t *shape); PyAPI_FUNC(void) _Py_add_one_to_index_C(int nd, Py_ssize_t *index, const Py_ssize_t *shape); PyAPI_DATA(PyTypeObject) _PyNamespace_Type; PyAPI_FUNC(PyObject *) _PyNamespace_New(PyObject *kwds); PyAPI_FUNC(int) _PyOS_IsMainThread(void); PyAPI_FUNC(void*) _PyOS_SigintEvent(void); PyAPI_FUNC(int) _PyOS_GetOpt(int argc, wchar_t **argv, wchar_t *optstring); PyAPI_FUNC(int) _PyOS_URandom(void *buffer, Py_ssize_t size); PyAPI_FUNC(int) _PyState_AddModule(PyObject*, struct PyModuleDef*); PyAPI_FUNC(PyThreadState *) _PyThreadState_Prealloc(PyInterpreterState *); PyAPI_FUNC(void) _PyThreadState_Init(PyThreadState *); PyAPI_FUNC(void) _PyThreadState_DeleteExcept(PyThreadState *tstate); PyAPI_FUNC(void) _PyGILState_Reinit(void); PyAPI_FUNC(PyThreadState *) _PyThreadState_UncheckedGet(void); PyAPI_FUNC(void) _PyUnicode_ClearStaticStrings(void); PyAPI_FUNC(int) _PyUnicode_EQ(PyObject *, PyObject *); PyAPI_FUNC(void) _Py_DumpTraceback(int fd, PyThreadState *tstate); PyAPI_FUNC(const char*) _Py_DumpTracebackThreads(int fd, PyInterpreterState *interp, PyThreadState *current_tstate); PyAPI_FUNC(void) _PyImportZip_Init(void); PyAPI_FUNC(PyObject *) _PyLong_GCD(PyObject *, PyObject *); All these names are not documented (except _PyObject_GC_Calloc accidentally mentioned in What's New in 3.5) and are not used implicitly in macros (except _PyObject_CallMethodId_SizeT used in _PyObject_CallMethodId). Many of these functions were added after implementing PEP 384 and changed its signature during its lifetime. They are not explicitly exclude from the stable API only by accident. ---------- components: Interpreter Core files: private_limited_api.diff keywords: patch messages: 264591 nosy: haypo, loewis, serhiy.storchaka priority: normal severity: normal stage: patch review status: open title: Exclude the private API from the stable API type: enhancement versions: Python 3.6 Added file: http://bugs.python.org/file42670/private_limited_api.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26900> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
