* gh-114685: Check flags in PyObject_GetBuffer() (GH-114707)Serhiy Storchaka2024-01-311-0/+6
| | | | | PyObject_GetBuffer() now raises a SystemError if called with PyBUF_READ or PyBUF_WRITE as flags. These flags should only be used with the PyMemoryView_* C API.

* gh-106672: C API: Report indiscriminately ignored errors (GH-106674)Serhiy Storchaka2023-11-071-18/+40
| | | | | Functions which indiscriminately ignore all errors now report them as unraisable errors.
* gh-76785: Move the Cross-Interpreter Code to Its Own File (gh-111502)Eric Snow2023-10-301-0/+1
| | | This is partly to clear this stuff out of pystate.c, but also in preparation for moving some code out of _xxsubinterpretersmodule.c. This change also moves this stuff to the internal API (new: Include/internal/pycore_crossinterp.h). @vstinner did this previously and I undid it. Now I'm re-doing it. :/
* gh-76785: Add SendChannel.send_buffer() (#110246)Eric Snow2023-10-091-0/+22
| | | (This is still a test module.)
* gh-108511: Add C API functions which do not silently ignore errors (GH-109025)Serhiy Storchaka2023-09-171-0/+18
| | | | | | | | | Add the following functions: * PyObject_HasAttrWithError() * PyObject_HasAttrStringWithError() * PyMapping_HasKeyWithError() * PyMapping_HasKeyStringWithError()
* gh-106307: Fix PyMapping_GetOptionalItemString() (GH-108797)Serhiy Storchaka2023-09-061-0/+2
| | | | | | The resulting pointer was not set to NULL if the creation of a temporary string object was failed. The tests were also missed due to oversight.
* gh-108765: Python.h no longer includes <ctype.h> (#108831)Victor Stinner2023-09-031-2/+1
| | | | | | | | | | | | | | | | | | | | | | | Remove <ctype.h> in C files which don't use it; only sre.c and _decimal.c still use it. Remove _PY_PORT_CTYPE_UTF8_ISSUE code from pyport.h: * Code added by commit b5047fd01948ab108edcc1b3c2c901d915814cfd in 2004 for MacOSX and FreeBSD. * Test removed by commit 52ddaefb6bab1a74ecffe8519c02735794ebfbe1 in 2007, since Python str type now uses locale independent functions like Py_ISALPHA() and Py_TOLOWER() and the Unicode database. Modules/_sre/sre.c replaces _PY_PORT_CTYPE_UTF8_ISSUE with new functions: sre_isalnum(), sre_tolower(), sre_toupper(). Remove unused includes: * _localemodule.c: remove <stdio.h>. * getargs.c: remove <float.h>. * dynload_win.c: remove <direct.h>, it no longer calls _getcwd() since commit fb1f68ed7cc1536482d1debd70a53c5442135fe2 (in 2001).

* gh-106084: Remove _PyObject_RealIsInstance() function (#106106)Victor Stinner2023-06-261-2/+2
| | | | | | | | | | | | | | | Remove the following functions from the public C API: * _PyObject_RealIsInstance() * _PyObject_RealIsSubclass() * _Py_add_one_to_index_F() * _Py_add_one_to_index_C() Move _PyObject_RealIsInstance() and _PyObject_RealIsSubclass() to the internal C API (pycore_abstract.h) and no longer export their symbols (in libpython). Make _Py_add_one_to_index_F() and _Py_add_one_to_index_C() functions static: no longer export them.
* gh-106084: Remove _PySequence_BytesToCharpArray() function (#106088)Victor Stinner2023-06-261-77/+0
| | | | | Remove private _PySequence_BytesToCharpArray() and _Py_FreeCharPArray() functions from the public C API: move these functions from Objects/abstract.c to Modules/_posixsubprocess.c.
* gh-85275: Remove old buffer APIs (#105137)Inada Naoki2023-06-021-9/+35

* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-1/+2
| | | | | | | | | | * 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-99537: Use Py_SETREF(var, NULL) in C code (#99687)Victor Stinner2022-11-231-6/+3
| | | Replace "Py_DECREF(var); var = NULL;" with "Py_SETREF(var, NULL);".
* gh-99300: Use Py_NewRef() in Objects/ directory (#99332)Victor Stinner2022-11-101-15/+7
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Objects/ directory.
* gh-93741: Add private C API _PyImport_GetModuleAttrString() (GH-93742)Serhiy Storchaka2022-06-141-8/+1
| | | | | | It combines PyImport_ImportModule() and PyObject_GetAttrString() and saves 4-6 lines of code on every use. Add also _PyImport_GetModuleAttr() which takes Python strings as arguments.
* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-041-11/+11
| | | | | | | | | | | | | | | | Currently, calling Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() may use a function call or a static inline function call, depending if the internal pycore_ceval.h header file is included or not. Use a different name for the static inline function to ensure that the static inline function is always used in Python internals for best performance. Similar approach than PyThreadState_GET() (function call) and _PyThreadState_GET() (static inline function). * Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate() * Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate() * pycore_ceval.h: Rename Py_EnterRecursiveCall() to _Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and _Py_LeaveRecursiveCall()

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-32/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-44977: Deprecate delegation of int to __trunc__ (GH-31031)Zackery Spytz2022-02-031-0/+5
| | | | | Calling int(a) when type(a) implements __trunc__ but not __int__ or __index__ now raises a DeprecationWarning.

* bpo-35134: Move classobject.h to Include/cpython/ (GH-28968)Victor Stinner2021-10-151-1/+0
| | | | | | | | | Move classobject.h, context.h, genobject.h and longintrepr.h header files from Include/ to Include/cpython/. Remove redundant "#ifndef Py_LIMITED_API" in context.h. Remove explicit #include "longintrepr.h" in C files. It's not needed, Python.h already includes it.
* 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 Stinner2021-10-111-2/+2

| | | | | | | | | | | | | | | When Python is built in debug mode (with C assertions), calling a type slot like sq_length (__len__() in Python) now fails with a fatal error if the slot succeeded with an exception set, or failed with no exception set. The error message contains the slot, the type name, and the current exception (if an exception is set). * Check the result of all slots using _Py_CheckSlotResult(). * No longer pass op_name to ternary_op() in release mode. * Replace operator with dunder Python method name in error messages. For example, replace "*" with "__mul__". * Fix compiler_exit_scope() when an exception is set. * Fix bytearray.extend() when an exception is set: don't call bytearray_setslice() with an exception set.
* bpo-42979: Enhance abstract.c assertions checking slot result (GH-24352)Victor Stinner2021-01-271-8/+9
| | | | | | | | * bpo-42979: Enhance abstract.c assertions checking slot result Add _Py_CheckSlotResult() function which fails with a fatal error if a slot function succeeded with an exception set or failed with no exception set: write the slot name, the type name and the current exception (if an exception is set).

| | | | | | | | | | | Enable recursion checks which were disabled when get __bases__ of non-type objects in issubclass() and isinstance() and when intern strings. It fixes a stack overflow when getting __bases__ leads to infinite recursion. Originally recursion checks was disabled for PyDict_GetItem() which silences all errors including the one raised in case of detected recursion and can return incorrect result. But now the code uses PyDict_GetItemWithError() and PyDict_SetDefault() instead.
