* gh-99300: Use Py_NewRef() in Python/ directory (#99302)Victor Stinner2022-11-101-4/+2
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Python/ directory.
* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-0/+1
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)Victor Stinner2021-10-111-1/+1
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* bpo-42157: unicodedata avoids references to UCD_Type (GH-22990)Victor Stinner2020-10-261-4/+2
| | | | | | | | | | * UCD_Check() uses PyModule_Check() * Simplify the internal _PyUnicode_Name_CAPI structure: * Remove size and state members * Remove state and self parameters of getcode() and getname() functions * Remove global_module_state
* bpo-1635741: _PyUnicode_Name_CAPI moves to internal C API (GH-22713)Victor Stinner2020-10-261-7/+10
| | | | | | | | | | The private _PyUnicode_Name_CAPI structure of the PyCapsule API unicodedata.ucnhash_CAPI moves to the internal C API. Moreover, the structure gets a new state member which must be passed to the getcode() and getname() functions. * Move Include/ucnhash.h to Include/internal/pycore_ucnhash.h * unicodedata module is now built with Py_BUILD_CORE_MODULE. * unicodedata: move hashAPI variable into unicodedata_module_state.

* bpo-41842: Add codecs.unregister() function (GH-22360)Hai Shi2020-09-281-0/+25
| | | | Add codecs.unregister() and PyCodec_Unregister() functions to unregister a codec search function.

| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-0/+1

| | | | | | | Replace _PyInterpreterState_Get() function call with _PyInterpreterState_GET_UNSAFE() macro which is more efficient but don't check if tstate or interp is NULL. _Py_GetConfigsAsDict() now uses _PyThreadState_GET().

| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).
* Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-051-1/+1
| | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.
