* bpo-45530: speed listobject.c's unsafe_tuple_compare() (GH-29076)Tim Peters2021-10-251-13/+64
| | | | | | | | Keep track of whether unsafe_tuple_compare() calls are resolved by the very first tuple elements, and adjust strategy accordingly. This can significantly cut the number of calls made to the full-blown PyObject_RichCompareBool(), and especially when duplicates are rare. Co-authored-by: Łukasz Langa <lukasz@langa.pl>

* bpo-45521: Fix a bug in the obmalloc radix tree code. (GH-29051)Neil Schemenauer2021-10-211-1/+1
| | | | | MAP_BOT_LENGTH was incorrectly used to compute MAP_TOP_MASK instead of MAP_TOP_LENGTH. On 64-bit machines, the error causes the tree to hold 46-bits of virtual addresses, rather than the intended 48-bits.
* bpo-45522: Allow to disable freelists on build time (GH-29056)Christian Heimes2021-10-216-26/+98
| | | | | | | | 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/longobject.h (GH-29044)Victor Stinner2021-10-192-0/+2
| | | | | | | | | | Move Include/longobject.h non-limited API to a new Include/cpython/longobject.h header file. Move the following definitions to the internal C API: * _PyLong_DigitValue * _PyLong_FormatAdvancedWriter() * _PyLong_FormatWriter()
* bpo-45256: Avoid C calls for most Python to Python calls. (GH-28937)Mark Shannon2021-10-181-1/+3
| | | | | | * Avoid making C calls for most calls to Python functions. * Change initialize_locals(steal=true) and _PyTuple_FromArraySteal to consume the argument references regardless of whether they succeed or fail.
* bpo-45482: Rename namespaceobject.h to pycore_namespace.h (GH-28975)Victor Stinner2021-10-152-2/+3
| | | | | | | | | Rename Include/namespaceobject.h to Include/internal/pycore_namespace.h. The _testmultiphase extension is now built with the Py_BUILD_CORE_MODULE macro defined to access _PyNamespace_Type. object.c: remove unused "pycore_context.h" include.
* bpo-35081: Move interpreteridobject.h to Include/internal/ (GH-28969)Victor Stinner2021-10-152-2/+2
| | | | Move the interpreteridobject.h header file from Include/ to Include/internal/. It only provides private functions.
* bpo-35134: Move classobject.h to Include/cpython/ (GH-28968)Victor Stinner2021-10-153-3/+0
| | | | | | | | | Move classobject.h, context.h, genobject.h and longintrepr.h header files from Include/ to Include/cpython/. Remove redundant "#ifndef Py_LIMITED_API" in context.h. Remove explicit #include "longintrepr.h" in C files. It's not needed, Python.h already includes it.

| | | Remove dead variables and control flow.
* bpo-35134: Add Include/cpython/floatobject.h (GH-28957)Victor Stinner2021-10-143-0/+4
| | | | | Split Include/floatobject.h into sub-files: add Include/cpython/floatobject.h and Include/internal/pycore_floatobject.h.
* bpo-45439: Move _PyObject_VectorcallTstate() to pycore_call.h (GH-28893)Victor Stinner2021-10-142-5/+43
| | | | | | | | | | | * 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-45434: pyport.h no longer includes <stdlib.h> (GH-28914)Victor Stinner2021-10-133-1/+4
| | | | | Include <stdlib.h> explicitly in C files. Python.h includes <wchar.h>.
* bpo-45434: Remove pystrhex.h header file (GH-28923)Victor Stinner2021-10-133-7/+7
| | | | | | | | | | | | | | | Move Include/pystrhex.h to Include/internal/pycore_strhex.h. The header file only contains private functions. The following C extensions are now built with Py_BUILD_CORE_MODULE macro defined to get access to the internal C API: * _blake2 * _hashopenssl * _md5 * _sha1 * _sha3 * _ssl * binascii
* bpo-45340: Don't create object dictionaries unless actually needed (GH-28802)Mark Shannon2021-10-133-231/+487
| | | | | | | | | | | | | | * Never change types' cached keys. It could invalidate inline attribute objects. * Lazily create object dictionaries. * Update specialization of LOAD/STORE_ATTR. * Don't update shared keys version for deletion of value. * Update gdb support to handle instance values. * Rename SPLIT_KEYS opcodes to INSTANCE_VALUE.
* pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)Victor Stinner2021-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | Redefining the PyThreadState_GET() macro in pycore_pystate.h is useless since it doesn't affect files not including it. Either use _PyThreadState_GET() directly, or don't use pycore_pystate.h internal C API. For example, the _testcapi extension don't use the internal C API, but use the public PyThreadState_Get() function instead. Replace PyThreadState_Get() with _PyThreadState_GET(). The _PyThreadState_GET() macro is more efficient than PyThreadState_Get() and PyThreadState_GET() function calls which call fail with a fatal Python error. posixmodule.c and _ctypes extension now include <windows.h> before pycore header files (like pycore_call.h). _PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead of PyErr_Fetch()/PyErr_Restore(). The _decimal and _xxsubinterpreters extensions are now built with the Py_BUILD_CORE_MODULE macro defined to get access to the internal C API.
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-1212-27/+37
| | | | | | | * 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 Stinner2021-10-1113-25/+25
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* bpo-45439: _PyObject_Call() only checks tp_vectorcall_offset once (GH-28890)Victor Stinner2021-10-111-23/+36
| | | | | | Add _PyVectorcall_Call() helper function. Add "assert(PyCallable_Check(callable));" to PyVectorcall_Call(), similar check than PyVectorcall_Function().
* bpo-45412: Remove Py_SET_ERRNO_ON_MATH_ERROR() macro (GH-28820)Victor Stinner2021-10-112-2/+4
| | | | | | | | | | | | | | | | | | | | | | 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()
* bpo-45256: Remove the usage of the C stack in Python to Python calls (GH-28488)Pablo Galindo Salgado2021-10-091-0/+20
