* bpo-40137: Add pycore_moduleobject.h internal header (GH-25507)Victor Stinner2021-04-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-42519: Replace PyMem_MALLOC() with PyMem_Malloc() (GH-23586)Victor Stinner2020-12-011-3/+3
| | | | | | | | | | | No longer use deprecated aliases to functions: * Replace PyMem_MALLOC() with PyMem_Malloc() * Replace PyMem_REALLOC() with PyMem_Realloc() * Replace PyMem_FREE() with PyMem_Free() * Replace PyMem_Del() with PyMem_Free() * Replace PyMem_DEL() with PyMem_Free() Modify also the PyMem_DEL() macro to use directly PyMem_Free().

* 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-40217: Ensure Py_VISIT(Py_TYPE(self)) is always called for ↵Pablo Galindo2020-05-271-0/+1

| | | | | | | | | | * PEP-384 _struct * More PEP-384 fixes for _struct Summary: Add a couple of more fixes for `_struct` that were previously missed such as removing `tp_*` accessors and using `PyBytesWriter` instead of calling `PyBytes_FromStringAndSize` with `NULL`. Also added a test to confirm that `iter_unpack` type is still uninstantiable. * 📜🤖 Added by blurb_it.

* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

* Rename struct.unpack() 2nd parameter to "buffer"Victor Stinner2017-02-021-4/+4
| | | | | | | | | | Issue #29300: Rename struct.unpack() second parameter from "inputstr" to "buffer", and use the Py_buffer type. Fix also unit tests on struct.unpack() which passed a Unicode string instead of a bytes string as struct.unpack() second parameter. The purpose of test_trailing_counter() is to test invalid format strings, not to test the buffer parameter.
* Issue #29300: Convert _struct module to Argument ClinicVictor Stinner2017-02-021-226/+246
| | | | | | | | | | | | | | | | | | | | | | | | | * The struct module now requires contiguous buffers. * Convert most functions and methods of the _struct module to Argument Clinic * Use "Py_buffer" type for the "buffer" argument. Argument Clinic is responsible to create and release the Py_buffer object. * Use "PyStructObject *" type for self to avoid explicit conversions. * Add an unit test on the _struct.Struct.unpack_from() method to test passing arguments as keywords. * Rephrase docstrings. * Rename "fmt" argument to "format" in docstrings and the documentation. As a side effect, functions and methods which used METH_VARARGS calling convention like struct.pack() now use the METH_FASTCALL calling convention which avoids the creation of temporary tuple to pass positional arguments and so is faster. For example, struct.pack("i", 1) becomes 1.56x faster (-36%):: $ ./python -m perf timeit \ -s 'import struct; pack=struct.pack' 'pack("i", 1)' \ --compare-to=../default-ref/python Median +- std dev: 119 ns +- 1 ns -> 76.8 ns +- 0.4 ns: 1.56x faster (-36%) Significant (t=295.91) Patch co-written with Serhiy Storchaka.

* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+1
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
