* gh-92135: Fix _Py_reinterpret_cast() for const (#92138)Victor Stinner2022-05-023-9/+18
| | | | | | | | | | 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.
* gh-90822: Make `PY_SSIZE_T_MAX` and `PY_SSIZE_T_MIN` constant expression ↵Ganesh Kathiresan2022-05-021-5/+6

* gh-89479: Export _Py_GetSpecializationStats() internal function (#92011)Victor Stinner2022-04-281-2/+3
| | | | | | When Python is built with "./configure --enable-pystats" (if the Py_STATS macro is defined), the _Py_GetSpecializationStats() function must be exported, since it's used by the _opcode extension which is built as a shared library.
* gh-91869: Fix tracing of specialized instructions with extended args (GH-91945)Dennis Sweeney2022-04-282-67/+68

* gh-91320: Add _Py_reinterpret_cast() macro (#91959)Victor Stinner2022-04-279-17/+39
| | | | | | | | | | | | | | Fix C++ compiler warnings about "old-style cast" (g++ -Wold-style-cast) in the Python C API. Use C++ reinterpret_cast<> and static_cast<> casts when the Python C API is used in C++. Example of fixed warning: Include/object.h:107:43: error: use of old-style cast to ‘PyObject*’ {aka ‘struct _object*’} [-Werror=old-style-cast] #define _PyObject_CAST(op) ((PyObject*)(op)) Add _Py_reinterpret_cast() and _Py_static_cast() macros.
* gh-91719: Add pycore_opcode.h internal header file (#91906)Victor Stinner2022-04-252-564/+583
| | | | | | | | | | | Move the following API from Include/opcode.h (public C API) to a new Include/internal/pycore_opcode.h header file (internal C API): * EXTRA_CASES * _PyOpcode_Caches * _PyOpcode_Deopt * _PyOpcode_Jump * _PyOpcode_OpName * _PyOpcode_RelativeJump
* gh-64783: Fix signal.NSIG value on FreeBSD (#91929)Victor Stinner2022-04-252-16/+35
| | | | | | | | | Fix signal.NSIG value on FreeBSD to accept signal numbers greater than 32, like signal.SIGRTMIN and signal.SIGRTMAX. * Add Py_NSIG constant. * Add pycore_signal.h internal header file. * _Py_Sigset_Converter() now includes the range of valid signals in the error message.
* gh-89653: PEP 670: Functions don't cast pointers (#91697)Victor Stinner2022-04-252-52/+113
| | | | | | | | | | | | | | | | | | | | | In the limited C API version 3.11 and newer, the following functions no longer cast their object pointer argument with _PyObject_CAST() or _PyObject_CAST_CONST(): * Py_REFCNT(), Py_TYPE(), Py_SIZE() * Py_SET_REFCNT(), Py_SET_TYPE(), Py_SET_SIZE() * Py_IS_TYPE() * Py_INCREF(), Py_DECREF() * Py_XINCREF(), Py_XDECREF() * Py_NewRef(), Py_XNewRef() * PyObject_TypeCheck() * PyType_Check() * PyType_CheckExact() Split Py_DECREF() implementation in 3 versions to make the code more readable. Update the xxlimited.c extension, which uses the limited C API version 3.11, to pass PyObject* to these functions.
* gh-80527: Deprecate PEP 623 Unicode functions (#91801)Victor Stinner2022-04-221-5/+11
| | | | | | | | | | | Deprecate functions: * PyUnicode_AS_DATA() * PyUnicode_AS_UNICODE() * PyUnicode_GET_DATA_SIZE() * PyUnicode_GET_SIZE() Previously, these functions were macros and so it wasn't possible to decorate them with Py_DEPRECATED().

* gh-89653: Add assertions to unicodeobject.h functions (#91800)Victor Stinner2022-04-211-0/+7

* gh-89653: PEP 670: Convert unicodeobject.h macros to functions (#91799)Victor Stinner2022-04-211-18/+44
| | | | | | | | | | | | Convert unicodeobject.h macros to static inline functions: * PyUnicode_AS_DATA() * PyUnicode_AS_UNICODE() * PyUnicode_GET_DATA_SIZE() * PyUnicode_GET_SIZE() Static inline functions are wrapped by macros which casts arguments with _PyObject_CAST() to prevent introducing new compiler warnings when passing "const PyObject*".
* gh-79315: Add Include/cpython/pythread.h header (#91798)Victor Stinner2022-04-212-44/+45

* gh-91768: C API no longer use "const PyObject*" type (#91769)Victor Stinner2022-04-212-15/+11
| | | | | | | | | | | | | Py_REFCNT(), Py_TYPE(), Py_SIZE() and Py_IS_TYPE() functions argument type is now "PyObject*", rather than "const PyObject*". * Replace also "const PyObject*" with "PyObject*" in functions: * _Py_strhex_impl() * _Py_strhex_with_sep() * _Py_strhex_bytes_with_sep() * Remove _PyObject_CAST_CONST() and _PyVarObject_CAST_CONST() macros. * Py_IS_TYPE() can now use Py_TYPE() in its implementation.
* gh-89653: PEP 670: Convert unicodeobject.h macros to functions (#91773)Victor Stinner2022-04-211-57/+74
| | | | | | | | | | | | | | | | | Convert unicodeobject.h macros to static inline functions: * PyUnicode_MAX_CHAR_VALUE() * PyUnicode_READ() * PyUnicode_READY() * PyUnicode_READ_CHAR() * PyUnicode_WRITE() Move PyUnicode_READY() after _PyUnicode_Ready(), since it uses _PyUnicode_Ready(). Static inline functions are wrapped by macros which casts arguments with _PyObject_CAST() and casts 'kind' arguments to "unsigned int" to prevent introducing new compiler warnings when passing "const PyObject*".
* GH-91719: Make MSVC generate somewhat faster switch code (#91718)Guido van Rossum2022-04-212-1/+79
| | | | | | | | | | | Apparently a switch on an 8-bit quantity where all cases are present generates a more efficient jump (doing only one indexed memory load instead of two). So we make opcode and use_tracing uint8_t, and generate a macro full of extra `case NNN:` lines for all unused opcodes. See https://github.com/faster-cpython/ideas/issues/321#issuecomment-1103263673
* GH-88116: Use a compact format to represent end line and column offsets. ↵Mark Shannon2022-04-212-27/+54

* gh-89653: PEP 670: Convert tuple macros to functions (#91786)Victor Stinner2022-04-212-11/+29
| | | | | | | | | | | | | | Convert macros to static inline functions: * PyTuple_GET_SIZE() * PyTuple_SET_ITEM() * PyList_GET_SIZE() * PyList_SET_ITEM() Add a macro converting arguments to PyTupleObject*, PyListObject* or PyObject* to prevent emitting new compiler warnings. According to PEP 670, PyTuple_GET_ITEM() and PyList_GET_ITEM() are left as macros.
* gh-91782: Define static_assert() macro on FreeBSD (#91787)Victor Stinner2022-04-211-0/+9
| | | | | On FreeBSD, if the static_assert() macro is not defined, define it in Python until <sys/cdefs.h> supports C11: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255290
* gh-89653: PEP 670: Convert PyWeakref_GET_OBJECT() to function (#91785)Victor Stinner2022-04-211-10/+16
| | | | | | Convert the PyWeakref_GET_OBJECT() macro to a static inline function. Add an assertion to check the argument with PyWeakref_Check(). Add a macro converting the argument to PyObject* to prevent emitting new compiler warning.
* gh-89653: PEP 670: Convert unicodeobject.h macros to functions (#91705)Victor Stinner2022-04-211-41/+61
| | | | | | | | | | | | | | | | | | Convert unicodeobject.h macros to static inline functions: * PyUnicode_CHECK_INTERNED() * PyUnicode_DATA(), _PyUnicode_COMPACT_DATA(), _PyUnicode_NONCOMPACT_DATA() * PyUnicode_GET_LENGTH() * PyUnicode_IS_ASCII() * PyUnicode_IS_COMPACT() * PyUnicode_IS_COMPACT_ASCII() * PyUnicode_IS_READY() Reorder functions to declare functions before their first usage. Static inline functions are wrapped by macros which casts arguments with _PyObject_CAST() to prevent introducing new compiler warnings when passing "const PyObject*".
