| | | | | | | | | | | | | | | | | | Move the follow functions and type from frameobject.h to pyframe.h, so the standard <Python.h> provide frame getter functions: * PyFrame_Check() * PyFrame_GetBack() * PyFrame_GetBuiltins() * PyFrame_GetGenerator() * PyFrame_GetGlobals() * PyFrame_GetLasti() * PyFrame_GetLocals() * PyFrame_Type Remove #include "frameobject.h" from many C files.

| | | | | | | | | | | * Fix the compatibility of the Python C API with C++ older than C++11. * _Py_NULL is only defined as nullptr on C++11 and newer. (cherry picked from commit 4caf5c2753f1aa28d6f4bc1aa377975fd2a62331) * test_cppext now builds the C++ extension with setuptools. * Add @test.support.requires_venv_with_pip.

| | | | | | | | | | (GH-93742) (GH-93792) It combines PyImport_ImportModule() and PyObject_GetAttrString() and saves 4-6 lines of code on every use. Add also _PyImport_GetModuleAttr() which takes Python strings as arguments. (cherry picked from commit 6fd4c8ec7740523bb81191c013118d9d6959bc9d)
* gh-93442: Make C++ version of _Py_CAST work with 0/NULL. (GH-93500) (gh-93507)Miss Islington (bot)2022-06-051-0/+14
| | | | | | | | | | | | | | | | | Add C++ overloads for _Py_CAST_impl() to handle 0/NULL. This will allow C++ extensions that pass 0 or NULL to macros using _Py_CAST() to continue to compile. Without this, you get an error like: invalid ‘static_cast’ from type ‘int’ to type ‘_object*’ The modern way to use a NULL value in C++ is to use nullptr. However, we want to not break extensions that do things the old way.

| | | | | | | | | | | | | (GH-93306) (cherry picked from commit caa279d6fd5f151e57f891cd4f6ba51b532501c6) This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing: * the configure option * the macro * the code enabled by the macro Automerge-Triggered-By: GH:ericsnowcurrently

| | | | | | | | | | | | | | | Use _Py_CAST() and _Py_STATIC_CAST() in macros wrapping static inline functions of unicodeobject.h. Change also the kind type from unsigned int to int: same parameter type than PyUnicode_FromKindAndData(). The limited API version 3.11 no longer casts arguments to expected types.

* gh-91321: Fix _PyObject_EXTRA_INIT for C++ (#92396)Victor Stinner2022-05-061-1/+1
| | | | | | | | In C++, the _PyObject_EXTRA_INIT macro now uses nullptr, rather than 0, to initialize the _ob_next and _ob_prev members of the PyObject structure. Fix test_cppext failure when Python is built with ./configure --with-trace-refs.
* gh-88279: Deprecate PySys_SetArgvEx() (#92363)Victor Stinner2022-05-061-3/+3

| | | | | | | | | | Convert the following macros to static inline functions: * PyCFunction_GET_CLASS() * PyCFunction_GET_FLAGS() * PyCFunction_GET_FUNCTION() * PyCFunction_GET_SELF() Limited C API version 3.11 no longer casts arguments.
* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-041-12/+8
| | | | | | | | | | | | | | | | Currently, calling Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() may use a function call or a static inline function call, depending if the internal pycore_ceval.h header file is included or not. Use a different name for the static inline function to ensure that the static inline function is always used in Python internals for best performance. Similar approach than PyThreadState_GET() (function call) and _PyThreadState_GET() (static inline function). * Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate() * Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate() * pycore_ceval.h: Rename Py_EnterRecursiveCall() to _Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and _Py_LeaveRecursiveCall()

* gh-91321: Fix PyModuleDef_HEAD_INIT on C++ (#92259)Victor Stinner2022-05-031-5/+5

* gh-91321: Add _Py_NULL macro (#92253)Victor Stinner2022-05-034-14/+22
| | | | | | | | Fix C++ compiler warnings: "zero as null pointer constant" (clang -Wzero-as-null-pointer-constant). * Add the _Py_NULL macro used by static inline functions to use nullptr in C++. * Replace NULL with nullptr in _testcppext.cpp.
* gh-91320: Fix more old-style cast warnings in C++ (#92247)Victor Stinner2022-05-032-16/+17
| | | | | | | Use _Py_CAST(), _Py_STATIC_CAST() and _PyASCIIObject_CAST() in static inline functions to fix C++ compiler warnings: "use of old-style cast" (clang -Wold-style-cast). test_cppext now builds the C++ test extension with -Wold-style-cast.
* gh-89653: PEP 670: Convert PyBytes macros to functions (#91990)Victor Stinner2022-05-032-10/+43

| | | | | | | | | | Fix C++ compiler warnings on cast macros, like _PyObject_CAST(), when casting a constant expression to a non constant type: use const_cast<> in C++. * In C++, Py_SAFE_DOWNCAST() now uses static_cast<> rather than reinterpret_cast<>. * Add tests to the _testcppext C++ extension. * test_cppext no longer captures stdout in verbose mode.
