* gh-90350: Optimize builtin functions min() and max() (GH-30286)colorfulappl2023-12-111-36/+45
| | | | Builtin functions min() and max() now use METH_FASTCALL
* gh-74616: Raise ValueError in case of null character in input prompt (GH-1738)Kushal Das2023-12-071-0/+5
| | | | | | | If the input prompt to the builtin input function on terminal has any null character, then raise ValueError instead of silently truncating it. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* gh-110014: Include explicitly <unistd.h> header (#110155)Victor Stinner2023-09-301-0/+5
| | | | | | | | | | | * Remove unused <locale.h> includes. * Remove unused <fcntl.h> include in traceback.h. * Remove redundant <assert.h> and <stddef.h> includes. They are already included by "Python.h". * Remove <object.h> include in faulthandler.c. Python.h already includes it. * Add missing <stdbool.h> in pycore_pythread.h if HAVE_PTHREAD_STUBS is defined. * Fix also warnings in pthread_stubs.h: don't redefine macros if they are already defined, like the __NEED_pthread_t macro.
* gh-109611: Add convenient C API function _PyFile_Flush() (GH-109612)Serhiy Storchaka2023-09-231-15/+7

* gh-108765: Python.h no longer includes <ctype.h> (#108831)Victor Stinner2023-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | 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-108634: Py_TRACE_REFS uses a hash table (#108663)Victor Stinner2023-08-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python built with "configure --with-trace-refs" (tracing references) is now ABI compatible with Python release build and debug build. Moreover, it now also supports the Limited API. Change Py_TRACE_REFS build: * Remove _PyObject_EXTRA_INIT macro. * The PyObject structure no longer has two extra members (_ob_prev and _ob_next). * Use a hash table (_Py_hashtable_t) to trace references (all objects): PyInterpreterState.object_state.refchain. * Py_TRACE_REFS build is now ABI compatible with release build and debug build. * Limited C API extensions can now be built with Py_TRACE_REFS: xxlimited, xxlimited_35, _testclinic_limited. * No longer rename PyModule_Create2() and PyModule_FromDefAndSpec2() functions to PyModule_Create2TraceRefs() and PyModule_FromDefAndSpec2TraceRefs(). * _Py_PrintReferenceAddresses() is now called before finalize_interp_delete() which deletes the refchain hash table. * test_tracemalloc find_trace() now also filters by size to ignore the memory allocated by _PyRefchain_Trace(). Test changes for Py_TRACE_REFS: * Add test.support.Py_TRACE_REFS constant. * Add test_sys.test_getobjects() to test sys.getobjects() function. * test_exceptions skips test_recursion_normalizing_with_no_memory() and test_memory_error_in_PyErr_PrintEx() if Python is built with Py_TRACE_REFS. * test_repl skips test_no_memory(). * test_capi skisp test_set_nomemory().
* gh-106320: Remove private pythonrun API (#108599)Victor Stinner2023-08-291-0/+1
| | | | | | | | | | | Remove these private functions from the public C API: * _PyRun_AnyFileObject() * _PyRun_InteractiveLoopObject() * _PyRun_SimpleFileObject() * _Py_SourceAsString() Move them to the internal C API: add a new pycore_pythonrun.h header file. No longer export these functions.
* gh-106320: Remove private _PySys functions (#108452)Victor Stinner2023-08-241-0/+1
| | | | | | | | | | Move private functions to the internal C API (pycore_sysmodule.h): * _PySys_GetAttr() * _PySys_GetSizeOf() No longer export most of these functions. Fix also a typo in Include/cpython/optimizer.h: add a missing space.

* gh-94673: Ensure Builtin Static Types are Readied Properly (gh-103940)Eric Snow2023-04-271-1/+1

* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-8/+8
| | | | | | | | | | * 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-102660: Fix Refleaks in import.c (#102744)Eric Snow2023-03-161-3/+0
| | | | | gh-102661 introduced some leaks. This fixes them. https://github.com/python/cpython/issues/102660
* gh-102660: Handle m_copy Specially for the sys and builtins Modules (gh-102661)Eric Snow2023-03-141-0/+3
| | | | | | | It doesn't make sense to use multi-phase init for these modules. Using a per-interpreter "m_copy" (instead of PyModuleDef.m_base.m_copy) makes this work okay. (This came up while working on gh-101660.) Note that we might instead end up disallowing re-load for sys/builtins since they are so special. https://github.com/python/cpython/issues/102660

| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* gh-99537: Use Py_SETREF(var, NULL) in C code (#99687)Victor Stinner2022-11-231-8/+4

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-42/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Clear more static types (GH-30796)Victor Stinner2022-01-221-5/+0
| | | | | | | * Move PyContext static types into object.c static_types list. * Rename PyContextTokenMissing_Type to _PyContextTokenMissing_Type and declare it in pycore_context.h. * _PyHamtItems types are no long exported: replace PyAPI_DATA() with extern.
* bpo-46417: Use _PyType_CAST() in Python directory (GH-30769)Victor Stinner2022-01-211-2/+2

* bpo-44024: Improve the TypeError message in getattr and hasattr (GH-25863)Géry Ogam2022-01-181-10/+0
| | | | | | Use common error message for non-string attribute name in the builtin functions getattr and hasattr. The special check no longer needed since Python 3.0.
* bpo-44525: Copy free variables in bytecode to allow calls to inner functions ↵Mark Shannon2021-11-231-2/+1
| | | | | | | | | | | to be specialized (GH-29595) * Make internal APIs that take PyFrameConstructor take a PyFunctionObject instead. * Add reference to function to frame, borrow references to builtins and globals. * Add COPY_FREE_VARS instruction to allow specialization of calls to inner functions.
* pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)Victor Stinner2021-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | Redefining the PyThreadState_GET() macro in pycore_pystate.h is useless since it doesn't affect files not including it. Either use _PyThreadState_GET() directly, or don't use pycore_pystate.h internal C API. For example, the _testcapi extension don't use the internal C API, but use the public PyThreadState_Get() function instead. Replace PyThreadState_Get() with _PyThreadState_GET(). The _PyThreadState_GET() macro is more efficient than PyThreadState_Get() and PyThreadState_GET() function calls which call fail with a fatal Python error. posixmodule.c and _ctypes extension now include <windows.h> before pycore header files (like pycore_call.h). _PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead of PyErr_Fetch()/PyErr_Restore(). The _decimal and _xxsubinterpreters extensions are now built with the Py_BUILD_CORE_MODULE macro defined to get access to the internal C API.
