* gh-111178: fix some USAN failures - mismatched function pointers (GH-123004)Bénédikt Tran2024-09-271-3/+3
|
* Replace PyObject_Del with PyObject_Free (#122453)Victor Stinner2024-08-011-1/+1
| | | | PyObject_Del() is just a alias to PyObject_Free() kept for backward compatibility. Use directly PyObject_Free() instead.
* gh-121288: Make error message for index() methods consistent (GH-121395)Serhiy Storchaka2024-07-051-1/+1
| | | | | | | | | Make error message for index() methods consistent Remove the repr of the searched value (which can be arbitrary large) from ValueError messages for list.index(), range.index(), deque.index(), deque.remove() and ShareableList.index(). Make the error messages consistent with error messages for other index() and remove() methods.
* gh-121040: Use __attribute__((fallthrough)) (#121044)Victor Stinner2024-06-271-1/+1
| | | | | | | | | | | | | Fix warnings when using -Wimplicit-fallthrough compiler flag. Annotate explicitly "fall through" switch cases with a new _Py_FALLTHROUGH macro which uses __attribute__((fallthrough)) if available. Replace "fall through" comments with _Py_FALLTHROUGH. Add _Py__has_attribute() macro. No longer define __has_attribute() macro if it's not defined. Move also _Py__has_builtin() at the top of pyport.h. Co-Authored-By: Nikita Sobolev <mail@sobolevn.me>

* gh-106320: Create pycore_modsupport.h header file (#106355)Victor Stinner2023-07-031-1/+2
| | | | | | | | | | Remove the following functions from the C API, move them to the internal C API: add a new pycore_modsupport.h internal header file: * PyModule_CreateInitialized() * _PyArg_NoKwnames() * _Py_VaBuildStack() No longer export these functions.
* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-1/+1
| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().
* gh-100726: Optimize construction of range object for medium sized integers ↵Pieter Eendebak2023-01-211-0/+58

* GH-91432: Specialize FOR_ITER (GH-91713)Dennis Sweeney2022-06-211-15/+8
| | | | | * Adds FOR_ITER_LIST and FOR_ITER_RANGE specializations. * Adds _PyLong_AssignValue() internal function to avoid temporary boxing of ints.
* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-45030: Fix integer overflow in __reduce__ of the range iterator (GH-28000)Serhiy Storchaka2021-09-041-16/+18

| | | | | | | | | | | | | * Add Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING, add to all relevant standard builtin classes. * Set relevant flags on collections.abc.Sequence and Mapping. * Use flags in MATCH_SEQUENCE and MATCH_MAPPING opcodes. * Inherit Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING. * Add NEWS * Remove interpreter-state map_abc and seq_abc fields.
* bpo-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)Victor Stinner2020-12-011-2/+2
| | | | | | | | | No longer use deprecated aliases to functions: * Replace PyObject_MALLOC() with PyObject_Malloc() * Replace PyObject_REALLOC() with PyObject_Realloc() * Replace PyObject_FREE() with PyObject_Free() * Replace PyObject_Del() with PyObject_Free() * Replace PyObject_DEL() with PyObject_Free()
* bpo-42161: Use _PyLong_GetZero() and _PyLong_GetOne() (GH-22995)Victor Stinner2020-10-271-22/+31

| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40170: Add _PyIndex_Check() internal function (GH-19426)Victor Stinner2020-04-081-2/+3
| | | | | | | | | Add _PyIndex_Check() function to the internal C API: fast inlined verson of PyIndex_Check(). Add Include/internal/pycore_abstract.h header file. Replace PyIndex_Check() with _PyIndex_Check() in C files of Objects and Python subdirectories.

* bpo-37207: Use vectorcall for range() (GH-18464)Petr Viktorin2020-02-181-17/+33
| | | | | | | This continues the `range()` part of #13930. The complete pull request is stalled on discussions around dicts, but `range()` should not be controversial. (And I plan to open PRs for other parts if this is merged.) On top of Mark's change, I unified `range_new` and `range_vectorcall`, which had a lot of duplicate code. https://bugs.python.org/issue37207

| | | | | | | | range_repr() (GH-8880) Also, propagate the error from PyNumber_AsSsize_t() because we don't care only about OverflowError which is not reported if the second argument is NULL. Reported by Svace static analyzer.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-6/+6
| | | | | | | | | (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.
* bpo-30592: Fixed error messages for some builtins. (#1996)Serhiy Storchaka2017-06-081-1/+1
