* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-30/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541

* bpo-46417: _curses uses PyStructSequence_NewType() (GH-30736)Victor Stinner2022-01-211-2/+9
| | | | | | | | The _curses module now creates its ncurses_version type as a heap type using PyStructSequence_NewType(), rather than using a static type. * Move _PyStructSequence_FiniType() definition to pycore_structseq.h. * test.pythoninfo: log curses.ncurses_version.
* bpo-46417: Finalize structseq types at exit (GH-30645)Victor Stinner2022-01-211-0/+30
| | | | | | | | | | | | | | | | | | Add _PyStructSequence_FiniType() and _PyStaticType_Dealloc() functions to finalize a structseq static type in Py_Finalize(). Currrently, these functions do nothing if Python is built in release mode. Clear static types: * AsyncGenHooksType: sys.set_asyncgen_hooks() * FlagsType: sys.flags * FloatInfoType: sys.float_info * Hash_InfoType: sys.hash_info * Int_InfoType: sys.int_info * ThreadInfoType: sys.thread_info * UnraisableHookArgsType: sys.unraisablehook * VersionInfoType: sys.version * WindowsVersionType: sys.getwindowsversion()
* bpo-46008: Make runtime-global object/type lifecycle functions and state ↵Eric Snow2021-12-091-3/+11
| | | | | | | | | | | | consistent. (gh-29998) This change is strictly renames and moving code around. It helps in the following ways: * ensures type-related init functions focus strictly on one of the three aspects (state, objects, types) * passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter * consistent naming conventions help make what's going on more clear * keeping API related to a type in the corresponding header file makes it more obvious where to look for it https://bugs.python.org/issue46008
* bpo-43916: Move the _PyStructSequence_InitType function to the internal API ↵Pablo Galindo2021-05-031-0/+1

* bpo-43916: Add Py_TPFLAGS_DISALLOW_INSTANTIATION type flag (GH-25721)Victor Stinner2021-04-301-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* bpo-43687: Py_Initialize() creates singletons earlier (GH-25147)Victor Stinner2021-04-021-1/+2
| | | | | Reorganize pycore_interp_init() to initialize singletons before the the first PyType_Ready() call. Fix an issue when Python is configured using --without-doc-strings.

| | | | | | | | | | | No longer use deprecated aliases to functions: * Replace PyMem_MALLOC() with PyMem_Malloc() * Replace PyMem_REALLOC() with PyMem_Realloc() * Replace PyMem_FREE() with PyMem_Free() * Replace PyMem_Del() with PyMem_Free() * Replace PyMem_DEL() with PyMem_Free() Modify also the PyMem_DEL() macro to use directly PyMem_Free().

* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-16/+59
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.
* bpo-40170: Use inline _PyType_HasFeature() function (GH-22375)Victor Stinner2020-09-231-1/+1
| | | | | Use _PyType_HasFeature() in the _io module and in structseq implementation. Replace PyType_HasFeature() opaque function call with _PyType_HasFeature() inlined function.

* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-2/+2
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.

| | | | | | | | | | | | Replace strncpy() with memcpy() in structseq_repr() to fix the following compiler warning: Objects/structseq.c:187:5: warning: 'strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] strncpy(pbuf, typ->tp_name, len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Objects/structseq.c:185:11: note: length computed here len = strlen(typ->tp_name) > TYPE_MAXSIZE ? TYPE_MAXSIZE : The function writes the terminating NUL byte later.
* bpo-34784: Implement correct cleanup in PyStructSequence new implementation ↵Pablo Galindo2018-11-151-0/+5
| | | | | | (GH-10536) PyTuple_Pack can fail and return NULL. If this happens, then PyType_FromSpecWithBases will incorrectly create a new type without bases. Also, it will crash on the Py_DECREF that follows. Also free members and type in error conditions.

| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

| | | | | | | | | | | | structseq.c _PyDict_GetItemId() is more efficient: it only builds the Unicode string once. Identifiers (dictionary keys) are now created at Python initialization, and if the creation failed, Python does exit with a fatal error. Before, PyDict_GetItemString() failure was not handled: structseq_new() could call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could also crash.
