* bpo-47164: Add _PyCFunction_CAST() macro (GH-32192)Victor Stinner2022-03-311-13/+13

* 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-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().

| | | | | | | | * 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

* bpo-40636: Clarify the zip built-in docstring. (GH-20118)Gregory P. Smith2020-05-151-5/+8
| | | | | | | | | | | | | | | | | | | | | Clarify the zip built-in docstring. This puts much simpler text up front along with an example. As it was, the zip built-in docstring was technically correct. But too technical for the reader who shouldn't _need_ to know about `__next__` and `StopIteration` as most people do not need to understand the internal implementation details of the iterator protocol in their daily life. This is a documentation only change, intended to be backported to 3.8; it is only tangentially related to PEP-618 which might offer new behavior options in the future. Wording based a bit more on enumerate per Brandt's suggestion. This gets rid of the legacy wording paragraph which seems too tied to implementation details of the iterator protocol which isn't relevant here. Co-authored-by: Brandt Bucher <brandtbucher@gmail.com>
* bpo-40334: Support type comments (GH-19780)Guido van Rossum2020-04-301-5/+1
| | | | | | | | | | This implements full support for # type: <type> comments, # type: ignore <stuff> comments, and the func_type parsing mode for ast.parse() and compile(). Closes https://github.com/we-like-parsers/cpython/issues/95. (For now, you need to use the master branch of mypy, since another issue unique to 3.9 had to be fixed there, and there's no mypy release yet.) The only thing missing is `feature_version=N`, which is being tracked in https://github.com/we-like-parsers/cpython/issues/124.
* bpo-40334: Use old compiler when compile mode is func_type (GH-19692)Guido van Rossum2020-04-231-1/+1
| | | | | This is invoked by mypy, using ast.parse(source, "<func_type>", "func_type"). Since the new grammar doesn't yet support the func_type_input start symbol we must use the old compiler in this case to prevent a crash. https://bugs.python.org/issue40334
* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-231-3/+3
| | | | | | | | | | | * Rename PyConfig.use_peg to _use_peg_parser * Document PyConfig._use_peg_parser and mark it a deprecated * Mark -X oldparser option and PYTHONOLDPARSER env var as deprecated in the documentation. * Add use_old_parser() and skip_if_new_parser() to test.support * Remove sys.flags.use_peg: use_old_parser() uses _testinternalcapi.get_configs() instead. * Enhance test_embed tests * subprocess._args_from_interpreter_flags() copies -X oldparser
