* gh-119127: Fix _functools.Placeholder singleton (#124601)Victor Stinner2024-09-261-13/+35
| | | | | | | * The module state now stores a strong reference to the Placeholder singleton. * Use a regular dealloc function. * Add Py_TPFLAGS_HAVE_GC flag and a traverse function to help the GC to collect the type when a _functools extension is unloaded.
* gh-119127: functools.partial placeholders (gh-119827)dgpb2024-09-261-53/+281

* gh-121027: Make the functools.partial object a method descriptor (GH-121089)Serhiy Storchaka2024-07-031-8/+1
| | | Co-authored-by: d.grigonis <dgrigonis@users.noreply.github.com>
* gh-121027: Add a future warning in functools.partial.__get__ (#121086)Serhiy Storchaka2024-06-271-0/+16
|
* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-0/+1
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).
* gh-118402: Fix inspect.signature() for functools.cmp_to_key() result (GH-118427)Serhiy Storchaka2024-04-301-0/+12

| | | | | | | code (GH-100244) in partial.__new__, before checking for the existence of the attribute 'func', first check whether the argument is an instance of partial.

| | | Replace _PyObject_FastCall() calls with PyObject_Vectorcall().
* gh-106084: Remove old PyObject call aliases (#106085)Victor Stinner2023-06-261-1/+1
| | | | | | | | | | | | | | Remove old aliases which were kept backwards compatibility with Python 3.8: * _PyObject_CallMethodNoArgs() * _PyObject_CallMethodOneArg() * _PyObject_CallOneArg() * _PyObject_FastCallDict() * _PyObject_Vectorcall() * _PyObject_VectorcallMethod() * _PyVectorcall_Function() Update code which used these aliases to use new names.
* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
* gh-99537: Use Py_SETREF() function in C code (#99656)Victor Stinner2022-11-221-2/+1
| | | | | | | | | | | | | | | 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 the global Dict-Related Versions to _PyRuntimeState (gh-99497)Eric Snow2022-11-161-0/+1
| | | | | We also move the global func version. https://github.com/python/cpython/issues/81057
* gh-99300: Use Py_NewRef() in Modules/ directory (#99466)Victor Stinner2022-11-141-46/+23
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in test C files of the Modules/ directory.

|
* gh-91320: Use _PyCFunction_CAST() (#92251)Victor Stinner2022-05-031-1/+1
| | | | | | | | | | Replace "(PyCFunction)(void(*)(void))func" cast with _PyCFunction_CAST(func). Change generated by the command: sed -i -e \ 's!(PyCFunction)(void(\*)(void)) *\([A-Za-z0-9_]\+\)!_PyCFunction_CAST(\1)!g' \ $(find -name "*.c")
* bpo-46613: Add PyType_GetModuleByDef to the public API (GH-31081)Petr Viktorin2022-02-111-1/+1
| | | | | * Make PyType_GetModuleByDef public (remove underscore) Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-45439: Move _PyObject_VectorcallTstate() to pycore_call.h (GH-28893)Victor Stinner2021-10-141-1/+1
| | | | | | | | | | | * Move _PyObject_VectorcallTstate() and _PyObject_FastCallTstate() to pycore_call.h (internal C API). * Convert PyObject_CallOneArg(), PyObject_Vectorcall(), _PyObject_FastCall() and PyVectorcall_Function() static inline functions to regular functions. * Add _PyVectorcall_FunctionInline() static inline function. * PyObject_Vectorcall(), _PyObject_FastCall(), and PyObject_CallOneArg() now call _PyThreadState_GET() rather than PyThreadState_Get().
* 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 Stinner2021-10-111-1/+1
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-191-1/+1
| | | | | The cast to PyCFunction is redundant. Overuse of redundant casts can hide actual bugs.
* bpo-45094: Add Py_NO_INLINE macro (GH-28140)Victor Stinner2021-09-031-1/+1
| | | | | * Rename _Py_NO_INLINE macro to Py_NO_INLINE: make it public and document it. * Sort macros in the C API documentation.
* bpo-43908: Make heap types converted during 3.10 alpha immutable (GH-26351)Erlend Egeberg Aasland2021-06-171-4/+6

* bpo-43916: Apply Py_TPFLAGS_DISALLOW_INSTANTIATION to selected types (GH-25748)Erlend Egeberg Aasland2021-04-301-2/+2
| | | | | | | | | | | | | | | | | | | | | Apply Py_TPFLAGS_DISALLOW_INSTANTIATION to the following types: * _dbm.dbm * _gdbm.gdbm * _multibytecodec.MultibyteCodec * _sre..SRE_Scanner * _thread._localdummy * _thread.lock * _winapi.Overlapped * array.arrayiterator * functools.KeyWrapper * functools._lru_list_elem * pyexpat.xmlparser * re.Match * re.Pattern * unicodedata.UCD * zlib.Compress * zlib.Decompress
* bpo-40137: Add pycore_moduleobject.h internal header (GH-25507)Victor Stinner2021-04-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pycore_moduleobject.h internal header file with static inline functions to access module members: * _PyModule_GetDict() * _PyModule_GetDef() * _PyModule_GetState() These functions don't check at runtime if their argument has a valid type and can be inlined even if Python is not built with LTO. _PyType_GetModuleByDef() uses _PyModule_GetDef(). Replace PyModule_GetState() with _PyModule_GetState() in the extension modules, considered as performance sensitive: * _abc * _functools * _operator * _pickle * _queue * _random * _sre * _struct * _thread * _winapi * array * posix The following extensions are now built with the Py_BUILD_CORE_MODULE macro defined, to be able to use the internal pycore_moduleobject.h header: _abc, array, _operator, _queue, _sre, _struct.

* bpo-42536: GC track recycled tuples (GH-23623)Brandt Bucher2020-12-051-0/+6
| | | | | | | | | | | | | | | | Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector: - collections.OrderedDict.items - dict.items - enumerate - functools.reduce - itertools.combinations - itertools.combinations_with_replacement - itertools.permutations - itertools.product - itertools.zip_longest - zip Previously, they could have become untracked by a prior garbage collection.
* 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: Modules/ uses _PyLong_GetZero() and _PyLong_GetOne() (GH-22998)Victor Stinner2020-10-271-1/+2
| | | | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Modules/ directory. _cursesmodule.c and zoneinfo.c are now built with Py_BUILD_CORE_MODULE macro defined.
