* Add more stats for freelist use and allocations. (GH-92211)Mark Shannon2022-05-031-0/+2
|
* gh-90667: Add specializations of Py_DECREF when types are known (GH-30872)Dennis Sweeney2022-04-191-14/+27
|
* 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-44954: Fix wrong result in float.fromhex corner case (GH-27834)Mark Dickinson2021-08-201-2/+2
|
* 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
| | | | | Co-authored-by: Guido van Rossum <guido@python.org> Co-authored-by: Talin <viridia@gmail.com> Co-authored-by: Pablo Galindo <pablogsal@gmail.com>
* 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.
* bpo-41873: Add vectorcall for float() (GH-22432)Dennis Sweeney2020-09-291-0/+19
|
* bpo-40521: Cleanup code of free lists (GH-21082)Victor Stinner2020-06-231-7/+14
| | | Add get_xxx_state() function to factorize duplicated code.
* bpo-40989: PyObject_INIT() becomes an alias to PyObject_Init() (GH-20901)Victor Stinner2020-06-151-2/+3
| | | | | | | | | | | | | | The PyObject_INIT() and PyObject_INIT_VAR() macros become aliases to, respectively, PyObject_Init() and PyObject_InitVar() functions. Rename _PyObject_INIT() and _PyObject_INIT_VAR() static inline functions to, respectively, _PyObject_Init() and _PyObject_InitVar(), and move them to pycore_object.h. Remove their return value: their return type becomes void. The _datetime module is now built with the Py_BUILD_CORE_MODULE macro defined. Remove an outdated comment on _Py_tracemalloc_config.
* bpo-40887: Don't use finalized free lists (GH-20700)Victor Stinner2020-06-081-3/+16
| | | | | | In debug mode, ensure that free lists are no longer used after being finalized. Set numfree to -1 in finalization functions (eg. _PyList_Fini()), and then check that numfree is not equal to -1 before using a free list (e.g list_dealloc()).
* bpo-40521: Make float free list per-interpreter (GH-20636)Victor Stinner2020-06-041-26/+29
| | | | | | | | Each interpreter now has its own float free list: * Move tuple numfree and free_list into PyInterpreterState. * Add _Py_float_state structure. * Add tstate parameter to _PyFloat_ClearFreeList() and _PyFloat_Fini().
* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-1/+1
| | | | | | | | | | | | (GH-20443) Previously, the result could have been an instance of a subclass of int. Also revert bpo-26202 and make attributes start, stop and step of the range object having exact type int. Add private function _PyNumber_Index() which preserves the old behavior of PyNumber_Index() for performance to use it in the conversion functions like PyLong_AsLong().
* bpo-37973: Improve the docstrings of sys.float_info (GH-19218)Zackery Spytz2020-05-241-2/+4
| | | Taken from https://docs.python.org/3/library/sys.html#sys.float_info
* bpo-37986: Improve perfomance of PyLong_FromDouble() (GH-15611)Sergey Fedoseev2020-05-101-21/+1
| | | | | | | | | * bpo-37986: Improve perfomance of PyLong_FromDouble() * Use strict bound check for safety and symmetry * Remove possibly outdated performance claims Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* bpo-40428: Remove PyTuple_ClearFreeList() function (GH-19769)Victor Stinner2020-04-291-7/+4
| | | | | | | | | | | | | | | | | | | Remove the following function from the C API: * PyAsyncGen_ClearFreeLists() * PyContext_ClearFreeList() * PyDict_ClearFreeList() * PyFloat_ClearFreeList() * PyFrame_ClearFreeList() * PyList_ClearFreeList() * PySet_ClearFreeList() * PyTuple_ClearFreeList() Make these functions private, move them to the internal C API and change their return type to void. Call explicitly PyGC_Collect() to free all free lists. Note: PySet_ClearFreeList() did nothing.
* bpo-35081: Move dtoa.h header to the internal C API (GH-18489)Victor Stinner2020-02-121-0/+1
| | | | | | | Move the dtoa.h header file to the internal C API as pycore_dtoa.h: it only contains private functions (prefixed by "_Py"). The math and cmath modules must now be compiled with the Py_BUILD_CORE macro defined.
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of this patch was generated automatically with: for name in \ PyObject_Vectorcall \ Py_TPFLAGS_HAVE_VECTORCALL \ PyObject_VectorcallMethod \ PyVectorcall_Function \ PyObject_CallOneArg \ PyObject_CallMethodNoArgs \ PyObject_CallMethodOneArg \ ; do echo $name git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g" done old=_PyObject_FastCallDict new=PyObject_VectorcallDict git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g" and then cleaned up: - Revert changes to in docs & news - Revert changes to backcompat defines in headers - Nudge misaligned comments
* bpo-39573: Add Py_SET_TYPE() function (GH-18394)Victor Stinner2020-02-071-1/+1
| | | Add Py_SET_TYPE() function to set the type of an object.
* bpo-39573: Use Py_TYPE() macro in Objects directory (GH-18392)Victor Stinner2020-02-071-3/+3
| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* Fix 5-space indentation and trailing whitespace (GH-18311)Mark Dickinson2020-02-021-11/+11
|
* bpo-39434: Improve float __floordiv__ performance and error message (GH-18147)Dong-hee Na2020-01-301-31/+39
|
* closes bpo-39415: Remove unused codes from longobject.c complexobject.c ↵Dong-hee Na2020-01-221-37/+0
| | | | floatobject.c. (GH-18105)
* bpo-38629: implement __floor__ and __ceil__ for float type (GH-16985)Batuhan Taşkaya2019-12-151-0/+30
|
* bpo-38835: Don't use PyFPE_START_PROTECT and PyFPE_END_PROTECT (GH-17231)Victor Stinner2019-11-201-20/+0
| | | | | The PyFPE_START_PROTECT() and PyFPE_END_PROTECT() macros are empty: they have been doing nothing for the last year (since commit 735ae8d139a673b30b321dc10acfd3d14f0d633b), so stop using them.
* bpo-38631: Avoid Py_FatalError() in float.__getformat__() (GH-17232)Victor Stinner2019-11-181-1/+2
| | | | Replace Py_FatalError() with a regular RuntimeError exception in float.__getformat__().
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-3/+3
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.
* bpo-38096: Clean up the "struct sequence" / "named tuple" docs (GH-15895)Raymond Hettinger2019-09-111-1/+1
| | | | | | | | * bpo-38096: Clean up the "struct sequence" / "named tuple" docs * Fix remaining occurrences of "struct sequence" * Repair a user visible docstring
* Make PyXXX_Fini() functions private (GH-15531)Victor Stinner2019-08-261-1/+1
| | | | | For example, rename PyTuple_Fini() to _PyTuple_Fini(). These functions are only declared in the internal C API.
