* bpo-38302: __pow__/__rpow__ now called when __ipow__ returns NotImplemented ↵Alex2021-02-261-21/+27

* bpo-40170: Always define PyIter_Check() as a function (GH-24548)Erlend Egeberg Aasland2021-02-161-5/+5

* bpo-42979: Use _Py_CheckSlotResult() to check slots result (GH-24356)Victor Stinner2021-01-291-187/+282
| | | | | | | | | | | | | | | 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).

* bpo-41974: Remove complex.__float__, complex.__floordiv__, etc (GH-22593)Serhiy Storchaka2020-10-091-5/+5
| | | | | | Remove complex special methods __int__, __float__, __floordiv__, __mod__, __divmod__, __rfloordiv__, __rmod__ and __rdivmod__ which always raised a TypeError.
* bpo-41909: Enable previously disabled recursion checks. (GH-22536)Serhiy Storchaka2020-10-041-2/+0
| | | | | | | | | | | 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.
* bpo-41428: Implementation for PEP 604 (GH-21515)Maggie Moss2020-09-091-6/+9
| | | | | See https://www.python.org/dev/peps/pep-0604/ for more information. Co-authored-by: Pablo Galindo <pablogsal@gmail.com>
* bpo-39573: Use the Py_TYPE() macro (GH-21433)Victor Stinner2020-07-101-2/+2
| | | Replace obj->ob_type with Py_TYPE(obj).
* bpo-41123: Remove PyLong_FromUnicode() (GH-21204)Inada Naoki2020-06-291-1/+1
|
* bpo-41103: Remove old buffer protocol support (#21117)Inada Naoki2020-06-251-79/+0
| | | They are deprecated since Python 3.0.
* bpo-36710: Pass tstate explicitly in abstract.c (GH-21075)Victor Stinner2020-06-231-40/+61
| | | | In functions calling more than one PyErr function, get tstate and then pass it explicitly.
* bpo-40824: Do not mask errors in __iter__ in "in" and the operator module. ↵Serhiy Storchaka2020-06-221-1/+3
| | | | | | | (GH-20537) Unexpected errors in calling the __iter__ method are no longer masked by TypeError in the "in" operator and functions operator.contains(), operator.indexOf() and operator.countOf().
* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-12/+20
| | | | | | | | | | | | (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-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-7/+24
| | | | Only __index__ should be used to make integer conversions lossless.
* bpo-38787: Add PyCFunction_CheckExact() macro for exact type checks (GH-20024)scoder2020-05-121-1/+1
| | | | | … now that we allow subtypes of PyCFunction. Also add PyCMethod_CheckExact() and PyCMethod_Check() for checks against the PyCMethod subtype.
* bpo-39465: Don't access directly _Py_Identifier members (GH-20043)Victor Stinner2020-05-111-1/+1
| | | | | * Replace id->object with _PyUnicode_FromId(&id) * Use _Py_static_string_init(str) macro to initialize statically name_op in typeobject.c.
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-4/+4
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-1/+1
|
* bpo-40170: Remove PyIndex_Check() macro (GH-19428)Victor Stinner2020-04-081-2/+0
| | | | | Always declare PyIndex_Check() as an opaque function to hide implementation details: remove PyIndex_Check() macro. The macro accessed directly the PyTypeObject.tp_as_number member.
* bpo-40170: Add _PyIndex_Check() internal function (GH-19426)Victor Stinner2020-04-081-9/+11
| | | | | | | | | Add _PyIndex_Check() function to the internal C API: fast inlined verson of PyIndex_Check(). Add Include/internal/pycore_abstract.h header file. Replace PyIndex_Check() with _PyIndex_Check() in C files of Objects and Python subdirectories.
* bpo-40170: Convert PyObject_CheckBuffer() macro to a function (GH-19376)Victor Stinner2020-04-071-0/+10
| | | | | Convert PyObject_CheckBuffer() macro to a function to hide implementation details: the macro accessed directly the PyTypeObject.tp_as_buffer member.
* bpo-39481: Implementation for PEP 585 (#18239)Guido van Rossum2020-04-071-0/+6
| | | | | | | | | | | | This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.
* bpo-39947: Move Py_EnterRecursiveCall() to internal C API (GH-18972)Victor Stinner2020-03-131-0/+1
| | | | | | Move the static inline function flavor of Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() to the internal C API: they access PyThreadState attributes. The limited C API provides regular functions which hide implementation details.
* bpo-38643: Raise SystemError instead of crashing when PyNumber_ToBase is ↵Serhiy Storchaka2020-03-091-9/+6
| | | | called with invalid base. (GH-18863)
* bpo-39573: Use Py_IS_TYPE() macro to check for types (GH-18809)Andy Lester2020-03-061-3/+2

* bpo-39382: Avoid dangling object use in abstract_issubclass() (GH-18530)Yonatan Goldschmidt2020-02-221-3/+9
| | | | | Hold reference of __bases__ tuple until tuple item is done with, because by dropping the reference the item may be destroyed.
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Use Py_TYPE() in abstract.c (GH-18390)Victor Stinner2020-02-071-94/+94
| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* Restore PyObject_IsInstance() comment (GH-18345)Victor Stinner2020-02-041-17/+23
| | | | | | | | | | | | Restore PyObject_IsInstance() comment explaining why only tuples of types are accepted, but not general sequence. Comment written by Guido van Rossum in commit 03290ecbf1661c0192e6abdbe00ae163af461d77 which implements isinstance(x, (A, B, ...)). The comment was lost in a PyObject_IsInstance() optimization: commit ec569b794737be248671d0dfac11b664fc930eef. Cleanup also the code. recursive_isinstance() is no longer recursive, so rename it to object_isinstance(), whereas object_isinstance() is recursive and so rename it to object_recursive_isinstance().
* bpo-38644: Pass tstate to Py_EnterRecursiveCall() (GH-16997)Victor Stinner2019-11-041-31/+49
| | | | | | | | | | | | | * Add _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() which require a tstate argument. * Pass tstate to _Py_MakeRecCheck() and _Py_CheckRecursiveCall(). * Convert Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() macros to static inline functions. _PyThreadState_GET() is the most efficient way to get the tstate, and so using it with _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() should be a little bit more efficient than using Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() which use the "slower" PyThreadState_GET().

* bpo-15913: Implement PyBuffer_SizeFromFormat() (GH-13873)Joannah Nanjekye2019-08-201-0/+42
| | | | Implement PyBuffer_SizeFromFormat() function (previously documented but not implemented): call struct.calcsize().
* bpo-37648: Fixed minor inconsistency in some __contains__. (GH-14904)Serhiy Storchaka2019-08-041-1/+1

* bpo-35992: Use PySequence_GetItem only if sq_item is not NULL (GH-11857)Ivan Levkivskyi2019-02-171-2/+5
| | | | Not using `__class_getitem__()` fallback if there is a non-subcriptable metaclass was caused by a certain asymmetry between how `PySequenceMethods` and `PyMappingMethods` are used in `PyObject_GetItem`. This PR removes this asymmetry. No tests failed, so I assume it was not intentional.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* closes bpo-34504: Remove the useless NULL check in PySequence_Check(). (GH-8935)Alexey Izbyshev2018-08-251-1/+1

* bpo-33738: Fix macros which contradict PEP 384 (GH-7477)Christian Tismer2018-06-091-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During development of the limited API support for PySide, we saw an error in a macro that accessed a type field. This patch fixes the 7 errors in the Python headers. Macros which were not written as capitals were implemented as function. To do the necessary analysis again, a script was included that parses all headers and looks for "->tp_" in serctions which can be reached with active limited API. It is easily possible to call this script as a test. Error listing: ../../Include/objimpl.h:243 #define PyObject_IS_GC(o) (PyType_IS_GC(Py_TYPE(o)) && \ (Py_TYPE(o)->tp_is_gc == NULL || Py_TYPE(o)->tp_is_gc(o))) Action: commented only ../../Include/objimpl.h:362 #define PyType_SUPPORTS_WEAKREFS(t) ((t)->tp_weaklistoffset > 0) Action: commented only ../../Include/objimpl.h:364 #define PyObject_GET_WEAKREFS_LISTPTR(o) \ ((PyObject **) (((char *) (o)) + Py_TYPE(o)->tp_weaklistoffset)) Action: commented only ../../Include/pyerrors.h:143 #define PyExceptionClass_Name(x) \ ((char *)(((PyTypeObject*)(x))->tp_name)) Action: implemented function ../../Include/abstract.h:593 #define PyIter_Check(obj) \ ((obj)->ob_type->tp_iternext != NULL && \ (obj)->ob_type->tp_iternext != &_PyObject_NextNotImplemented) Action: implemented function ../../Include/abstract.h:713 #define PyIndex_Check(obj) \ ((obj)->ob_type->tp_as_number != NULL && \ (obj)->ob_type->tp_as_number->nb_index != NULL) Action: implemented function ../../Include/abstract.h:924 #define PySequence_ITEM(o, i)\ ( Py_TYPE(o)->tp_as_sequence->sq_item(o, i) ) Action: commented only
