* gh-92203: Add closure support to exec(). (#92204)larryhastings2022-05-061-8/+52
| | | Add a closure keyword-only parameter to exec(). It can only be specified when exec-ing a code object that uses free variables. When specified, it must be a tuple, with exactly the number of cell variables referenced by the code object. closure has a default value of None, and it must be None if the code object doesn't refer to any free variables.

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-42/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-46417: Clear more static types (GH-30796)Victor Stinner2022-01-221-5/+0
| | | | | | | * Move PyContext static types into object.c static_types list. * Rename PyContextTokenMissing_Type to _PyContextTokenMissing_Type and declare it in pycore_context.h. * _PyHamtItems types are no long exported: replace PyAPI_DATA() with extern.
* bpo-46417: Use _PyType_CAST() in Python directory (GH-30769)Victor Stinner2022-01-211-2/+2

* bpo-44024: Improve the TypeError message in getattr and hasattr (GH-25863)Géry Ogam2022-01-181-10/+0
| | | | | | Use common error message for non-string attribute name in the builtin functions getattr and hasattr. The special check no longer needed since Python 3.0.
* bpo-44525: Copy free variables in bytecode to allow calls to inner functions ↵Mark Shannon2021-11-231-2/+1
| | | | | | | | | | | to be specialized (GH-29595) * Make internal APIs that take PyFrameConstructor take a PyFunctionObject instead. * Add reference to function to frame, borrow references to builtins and globals. * Add COPY_FREE_VARS instruction to allow specialization of calls to inner functions.
* 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 Stinner2021-10-121-0/+1
| | | | | | | * 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 Stinner2021-10-111-1/+1
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().

* bpo-43413: Fix handling keyword arguments in subclasses of some buitin ↵Serhiy Storchaka2021-09-121-2/+4
| | | | | | | | classes (GH-26456) * Constructors of subclasses of some buitin classes (e.g. tuple, list, frozenset) no longer accept arbitrary keyword arguments. * Subclass of set can now define a __new__() method with additional keyword parameters without overriding also __init__().
* bpo-45123: PyAiter_Check and PyObject_GetAiter fix & rename. (GH-28194)Yury Selivanov2021-09-071-1/+1
| | | | | | | | Fix PyAiter_Check to only check for the `__anext__` presense (not for `__aiter__`). Rename `PyAiter_Check()` to `PyAIter_Check()`, `PyObject_GetAiter()` -> `PyObject_GetAIter()`. Co-authored-by: Pablo Galindo Salgado <Pablogsal@gmail.com>

* bpo-43244: Remove Yield macro from pycore_ast.h (GH-25243)Victor Stinner2021-04-071-1/+0
| | | | | | | | * pycore_ast.h no longer defines the Yield macro. * Fix a compiler warning on Windows: "warning C4005: 'Yield': macro redefinition". * Python-ast.c now defines directly functions with their real _Py_xxx() name, rather than xxx(). * Remove "#undef Yield" in C files including pycore_ast.h.

* bpo-43244: Remove the pyarena.h header (GH-25007)Victor Stinner2021-03-241-4/+4
| | | | | | | | | | | | | | | | | | Remove the pyarena.h header file with functions: * PyArena_New() * PyArena_Free() * PyArena_Malloc() * PyArena_AddPyObject() These functions were undocumented, excluded from the limited C API, and were only used internally by the compiler. Add pycore_pyarena.h header. Rename functions: * PyArena_New() => _PyArena_New() * PyArena_Free() => _PyArena_Free() * PyArena_Malloc() => _PyArena_Malloc() * PyArena_AddPyObject() => _PyArena_AddPyObject()
* bpo-43244: Add pycore_compile.h header file (GH-25000)Victor Stinner2021-03-231-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the compiler functions using "struct _mod" type, because the public AST C API was removed: * PyAST_Compile() * PyAST_CompileEx() * PyAST_CompileObject() * PyFuture_FromAST() * PyFuture_FromASTObject() These functions were undocumented and excluded from the limited C API. Rename functions: * PyAST_CompileObject() => _PyAST_Compile() * PyFuture_FromASTObject() => _PyFuture_FromAST() Moreover, _PyFuture_FromAST() is no longer exported (replace PyAPI_FUNC() with extern). _PyAST_Compile() remains exported for test_peg_generator. Remove also compatibility functions: * PyAST_Compile() * PyAST_CompileEx() * PyFuture_FromAST()

* bpo-43244: Remove ast.h, asdl.h, Python-ast.h headers (GH-24933)Victor Stinner2021-03-231-2/+1
| | | | | | | | | | | | | | | | These functions were undocumented and excluded from the limited C API. Most names defined by these header files were not prefixed by "Py" and so could create names conflicts. For example, Python-ast.h defined a "Yield" macro which was conflict with the "Yield" name used by the Windows <winbase.h> header. Use the Python ast module instead. * Move Include/asdl.h to Include/internal/pycore_asdl.h. * Move Include/Python-ast.h to Include/internal/pycore_ast.h. * Remove ast.h header file. * pycore_symtable.h no longer includes Python-ast.h.

* bpo-43244: Remove the PyAST_Validate() function (GH-24911)Victor Stinner2021-03-181-1/+2
| | | | | | | | | | | | Remove the PyAST_Validate() function. It is no longer possible to build a AST object (mod_ty type) with the public C API. The function was already excluded from the limited C API (PEP 384). Rename PyAST_Validate() function to _PyAST_Validate(), move it to the internal C API, and don't export it anymore (replace PyAPI_FUNC with extern). The function was added in bpo-12575 by the commit 832bfe2ebd5ecfa92031cd40c8b41835ba90487f.

* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-2/+2
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
* bpo-42990: Further refactoring of PyEval_ functions. (GH-24368)Mark Shannon2021-02-011-3/+4
| | | | | | | | | | * Further refactoring of PyEval_EvalCode and friends. Break into make-frame, and eval-frame parts. * Simplify function vector call using new _PyEval_Vector. * Remove unused internal functions: _PyEval_EvalCodeWithName and _PyEval_EvalCode. * Don't use legacy function PyEval_EvalCodeEx.
* bpo-42536: GC track recycled tuples (GH-23623)Brandt Bucher2020-12-051-0/+5
| | | | | | | | | | | | | | | | Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector: - collections.OrderedDict.items - dict.items - enumerate - functools.reduce - itertools.combinations - itertools.combinations_with_replacement - itertools.permutations - itertools.product - itertools.zip_longest - zip Previously, they could have become untracked by a prior garbage collection.
* bpo-42519: Replace PyMem_MALLOC() with PyMem_Malloc() (GH-23586)Victor Stinner2020-12-011-1/+1
| | | | | | | | | | | 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-42152: Use PyDict_Contains and PyDict_SetDefault if appropriate. (GH-22986)Serhiy Storchaka2020-10-261-10/+10
| | | | | | | If PyDict_GetItemWithError is only used to check whether the key is in dict, it is better to use PyDict_Contains instead. And if it is used in combination with PyDict_SetItem, PyDict_SetDefault can replace the combination.
* bpo-41078: Fix bltinmodule.c with Py_TRACE_REFS (GH-21058)Victor Stinner2020-06-221-0/+1
| | | | Add pycore_object.h include to fix bltinmodule.c when Py_TRACE_REFS macro is defined.
