* 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-106320: Remove private AC converter functions (#108505)Victor Stinner2023-08-261-0/+1
| | | | | | | | | | | | | | Move these private functions to the internal C API (pycore_abstract.h): * _Py_convert_optional_to_ssize_t() * _PyNumber_Index() Argument Clinic now emits #include "pycore_abstract.h" when these functions are used. The parser of the c-analyzer tool now uses a list of files which use the limited C API, rather than a list of files using the internal C API.
* gh-106320: Remove private _PyObject C API (#107147)Victor Stinner2023-07-231-1/+1
| | | | | | | | | | | | | | | | Move private debug _PyObject functions to the internal C API (pycore_object.h): * _PyDebugAllocatorStats() * _PyObject_CheckConsistency() * _PyObject_DebugTypeStats() * _PyObject_IsFreed() No longer export most of these functions, except of _PyObject_IsFreed(). Move test functions using _PyObject_IsFreed() from _testcapi to _testinternalcapi. check_pyobject_is_freed() test no longer catch _testcapi.error: the tested function cannot raise _testcapi.error.
* gh-106320: Create pycore_modsupport.h header file (#106355)Victor Stinner2023-07-031-0/+1
| | | | | | | | | | 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-104263: Rely on Py_NAN and introduce Py_INFINITY (GH-104202)Sebastian Berg2023-05-101-12/+1
| | | | | | | | | | This PR removes `_Py_dg_stdnan` and `_Py_dg_infinity` in favour of using the standard `NAN` and `INFINITY` macros provided by C99. This change has the side-effect of fixing a bug on MIPS where the hard-coded value used by `_Py_dg_stdnan` gave a signalling NaN rather than a quiet NaN. --------- Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* gh-94673: Properly Initialize and Finalize Static Builtin Types for Each ↵Eric Snow2023-05-021-5/+4
| | | | | Interpreter (gh-104072) Until now, we haven't been initializing nor finalizing the per-interpreter state properly.
* gh-84436: Immortalize in _PyStructSequence_InitBuiltinWithFlags() (gh-104054)Eric Snow2023-05-011-2/+2
| | | This also does some cleanup.
* gh-94673: Ensure Builtin Static Types are Readied Properly (gh-103940)Eric Snow2023-04-271-13/+3
| | | There were cases where we do unnecessary work for builtin static types. This also simplifies some work necessary for a per-interpreter GIL.
* gh-101825: Clarify that as_integer_ratio() output is always normalized (#101843)Sergey B Kirpichev2023-02-271-6/+4
| | | | | | | | | Make docstrings for `as_integer_ratio` consistent across types, and document that the returned pair is always normalized (coprime integers, with positive denominator). --------- Co-authored-by: Owain Davies <116417456+OTheDev@users.noreply.github.com> Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* gh-99537: Use Py_SETREF() function in C code (#99657)Victor Stinner2022-11-221-6/+3
| | | | | | | | | | | | | | | Fix potential race condition in code patterns: * Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);" * Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);" * Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);" Other changes: * Replace "old = var; var = new; Py_DECREF(var)" with "Py_SETREF(var, new);" * Replace "old = var; var = new; Py_XDECREF(var)" with "Py_XSETREF(var, new);" * And remove the "old" variable.
* gh-81057: Move More Globals in Core Code to _PyRuntimeState (gh-99516)Eric Snow2022-11-161-10/+17
| | | https://github.com/python/cpython/issues/81057
* gh-99300: Use Py_NewRef() in Objects/ directory (#99335)Victor Stinner2022-11-101-9/+8
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Objects/ directory.
* gh-95605: Fix `float(s)` error message when `s` contains only whitespace ↵Mark Dickinson2022-08-101-1/+8
| | | | | (GH-95665) This PR fixes the error message from float(s) in the case where s contains only whitespace.
* gh-94673: Add _PyStaticType_InitBuiltin() (#95152)Eric Snow2022-07-251-1/+2
| | | | | | | | | | | | This is the first of several precursors to storing tp_subclasses (and tp_weaklist) on the interpreter state for static builtin types. We do the following: * add `_PyStaticType_InitBuiltin()` * add `_Py_TPFLAGS_STATIC_BUILTIN` * set it on all static builtin types in `_PyStaticType_InitBuiltin()` * shuffle some code around to be able to use _PyStaticType_InitBuiltin() * rename `_PyStructSequence_InitType()` to `_PyStructSequence_InitBuiltinWithFlags()` * add `_PyStructSequence_InitBuiltin()`.
* Fix missing word in sys.float_info docstring (GH-93489)Mark Dickinson2022-06-041-1/+1

* bpo-46906: Add PyFloat_Pack8() to the C API (GH-31657)Victor Stinner2022-03-111-7/+13
| | | | | | | | | | | | | | | | | | | | | | Add new functions to pack and unpack C double (serialize and deserialize): * PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8() * PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8() Document these functions and add unit tests. Rename private functions and move them from the internal C API to the public C API: * _PyFloat_Pack2() => PyFloat_Pack2() * _PyFloat_Pack4() => PyFloat_Pack4() * _PyFloat_Pack8() => PyFloat_Pack8() * _PyFloat_Unpack2() => PyFloat_Unpack2() * _PyFloat_Unpack4() => PyFloat_Unpack4() * _PyFloat_Unpack8() => PyFloat_Unpack8() Replace the "unsigned char*" type with "char*" which is more common and easy to use.
* bpo-46852: Remove the float.__set_format__() method (GH-31585)Victor Stinner2022-02-251-74/+2
| | | | | | Remove the undocumented private float.__set_format__() method, previously known as float.__set_format__() in Python 3.7. Its docstring said: "You probably don't want to use this function. It exists mainly to be used in Python's test suite."
* bpo-46852: Rename float.__set_format__() to float.__setformat__() (GH-31558)Victor Stinner2022-02-251-5/+5
| | | | | | | | | | | Rename the private undocumented float.__set_format__() method to float.__setformat__() to fix a typo introduced in Python 3.7. The method is only used by test_float. The change enables again test_float tests on the float format which were previously skipped because of the typo. The typo was introduced in Python 3.7 by bpo-20185 in commit b5c51d3dd95bbfde533655fb86ac0f96f771ba7b.
* bpo-46656: Remove Py_NO_NAN macro (GH-31160)Victor Stinner2022-02-251-8/+0
| | | | Building Python now requires support for floating point Not-a-Number (NaN): remove the Py_NO_NAN macro.
* bpo-45412: Add _PY_SHORT_FLOAT_REPR macro (GH-31171)Victor Stinner2022-02-231-8/+8
| | | | | | | | | | Remove the HAVE_PY_SET_53BIT_PRECISION macro (moved to the internal C API). * Move HAVE_PY_SET_53BIT_PRECISION macro to pycore_pymath.h. * Replace PY_NO_SHORT_FLOAT_REPR macro with _PY_SHORT_FLOAT_REPR macro which is always defined. gcc -Wundef emits a warning when using _PY_SHORT_FLOAT_REPR but the macro is not defined, if pycore_pymath.h include was forgotten.
* bpo-46417: Use _PyType_CAST() in Objects directory (GH-30764)Victor Stinner2022-01-211-1/+1
|
* bpo-46417: _curses uses PyStructSequence_NewType() (GH-30736)Victor Stinner2022-01-211-0/+1
| | | | | | | | 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/+8
| | | | | | | | | | | | | | | | | | 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()
* Revert "bpo-46131: add fastpath for PyFloat_Check() (GH-30200)" (GH-30208)Raymond Hettinger2021-12-191-1/+0
| | | This reverts commit 2ef06d412531d1163dbc72877c88aedf3ed82a25.
* bpo-46131: add fastpath for PyFloat_Check() (#30200)Matti Picus2021-12-191-0/+1

* bpo-46008: Make runtime-global object/type lifecycle functions and state ↵Eric Snow2021-12-091-5/+19
| | | | | | | | | | | | 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-45522: Allow to disable freelists on build time (GH-29056)Christian Heimes2021-10-211-4/+17
| | | | | | | | Freelists for object structs can now be disabled. A new ``configure`` option ``--without-freelists`` can be used to disable all freelists except empty tuple singleton. Internal Py*_MAXFREELIST macros can now be defined as 0 without causing compiler warnings and segfaults. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-35134: Add Include/cpython/floatobject.h (GH-28957)Victor Stinner2021-10-141-0/+1
| | | | | Split Include/floatobject.h into sub-files: add Include/cpython/floatobject.h and Include/internal/pycore_floatobject.h.
* bpo-45434: pyport.h no longer includes <stdlib.h> (GH-28914)Victor Stinner2021-10-131-0/+1
| | | | | Include <stdlib.h> explicitly in C files. Python.h includes <wchar.h>.
* bpo-45412: Remove Py_SET_ERRNO_ON_MATH_ERROR() macro (GH-28820)Victor Stinner2021-10-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | Remove the following math macros using the errno variable: * Py_ADJUST_ERANGE1() * Py_ADJUST_ERANGE2() * Py_OVERFLOWED() * Py_SET_ERANGE_IF_OVERFLOW() * Py_SET_ERRNO_ON_MATH_ERROR() Create pycore_pymath.h internal header file. Rename Py_ADJUST_ERANGE1() and Py_ADJUST_ERANGE2() to _Py_ADJUST_ERANGE1() and _Py_ADJUST_ERANGE2(), and convert these macros to static inline functions. Move the following macros to pycore_pymath.h: * _Py_IntegralTypeSigned() * _Py_IntegralTypeMax() * _Py_IntegralTypeMin() * _Py_InIntegralTypeRange()
* Fix typos in the Objects directory (GH-28766)Christian Clauss2021-10-061-1/+1

* bpo-43475: Fix worst case collision behavior for NaN instances (GH-25493)Raymond Hettinger2021-04-221-1/+1
|
* bpo-43687: Py_Initialize() creates singletons earlier (GH-25147)Victor Stinner2021-04-021-3/+7
| | | | | 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.
* bpo-42128: Structural Pattern Matching (PEP 634) (GH-22917)Brandt Bucher2021-02-261-1/+2

* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-5/+5
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
* 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 Stinner2020-10-271-5/+14
| | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Objects/ and Python/ directories.
* bpo-41974: Remove complex.__float__, complex.__floordiv__, etc (GH-22593)Serhiy Storchaka2020-10-091-1/+1
| | | | | | Remove complex special methods __int__, __float__, __floordiv__, __mod__, __divmod__, __rfloordiv__, __rmod__ and __rdivmod__ which always raised a TypeError.
