* bpo-43682: Make staticmethod objects callable (GH-25117)Victor Stinner2021-04-121-1/+8
| | | Static methods (@staticmethod) are now callable as regular functions.
* bpo-43682: @staticmethod inherits attributes (GH-25268)Victor Stinner2021-04-091-9/+71
| | | | | | | | | | Static methods (@staticmethod) and class methods (@classmethod) now inherit the method attributes (__module__, __name__, __qualname__, __doc__, __annotations__) and have a new __wrapped__ attribute. Changes: * Add a repr() method to staticmethod and classmethod types. * Add tests on the @classmethod decorator.
* bpo-43541: Fix PyEval_EvalCodeEx() regression (GH-24918)Victor Stinner2021-03-181-1/+1
| | | | | | | | | | | * Remove an assertion which required CO_NEWLOCALS and CO_OPTIMIZED code flags. It is ok to call this function on a code with these flags set. * Fix reference counting on builtins: remove Py_DECREF(). Fix regression introduced in the commit 46496f9d12582bf11f4911ad0f23315d6f277907. Add also a comment to document that _PyEval_BuiltinsFromGlobals() returns a borrowed reference.
* bpo-42990: Functions inherit current builtins (GH-24564)Victor Stinner2021-02-201-2/+6
| | | | | | | | | | | | | | | | | | | | The types.FunctionType constructor now inherits the current builtins if the globals dictionary has no "__builtins__" key, rather than using {"None": None} as builtins: same behavior as eval() and exec() functions. Defining a function with "def function(...): ..." in Python is not affected, globals cannot be overriden with this syntax: it also inherits the current builtins. PyFrame_New(), PyEval_EvalCode(), PyEval_EvalCodeEx(), PyFunction_New() and PyFunction_NewWithQualName() now inherits the current builtins namespace if the globals dictionary has no "__builtins__" key. * Add _PyEval_GetBuiltins() function. * _PyEval_BuiltinsFromGlobals() now uses _PyEval_GetBuiltins() if builtins cannot be found in globals. * Add tstate parameter to _PyEval_BuiltinsFromGlobals().
* bpo-42990: Refactor _PyFrame_New_NoTrack() (GH-24566)Victor Stinner2021-02-181-52/+59
| | | | | | | | | | | | * Refactor _PyFrame_New_NoTrack() and PyFunction_NewWithQualName() code. * PyFrame_New() checks for _PyEval_BuiltinsFromGlobals() failure. * Fix a ref leak in _PyEval_BuiltinsFromGlobals() error path. * Complete PyFunction_GetModule() documentation: it returns a borrowed reference and it can return NULL. * Move _PyEval_BuiltinsFromGlobals() definition to the internal C API. * PyFunction_NewWithQualName() uses _Py_IDENTIFIER() API for the "__name__" string to make it compatible with subinterpreters.
* bpo-42990: Add __builtins__ attribute to functions (GH-24559)Victor Stinner2021-02-181-0/+1
| | | | | | Expose the new PyFunctionObject.func_builtins member in Python as a new __builtins__ attribute on functions. Document also the behavior change in What's New in Python 3.10.
* bpo-42990: Further refactoring of PyEval_ functions. (GH-24368)Mark Shannon2021-02-011-2/+2
| | | | | | | | | | * 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-42990: Introduce 'frame constructor' struct to simplify API for ↵Mark Shannon2021-01-291-2/+11
| | | | | | | PyEval_CodeEval and friends (GH-24298) * Introduce 'frame constructor' to simplify API for frame creation * Embed struct using a macro to conform to PEP 7
* bpo-42202: Store func annotations as a tuple (GH-23316)Yurii Karabas2020-11-251-0/+19
| | | | | | | | | | | | | Reduce memory footprint and improve performance of loading modules having many func annotations. >>> sys.getsizeof({"a":"int","b":"int","return":"int"}) 232 >>> sys.getsizeof(("a","int","b","int","return","int")) 88 The tuple is converted into dict on the fly when `func.__annotations__` is accessed first.

* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-36347: stop using RESTRICTED constants (GH-12684)Jeroen Demeyer2020-02-181-6/+4
| | | | | | | | The constants `RESTRICTED` and `PY_WRITE_RESTRICTED` no longer have a meaning in Python 3. Therefore, CPython should not use them. CC @matrixise https://bugs.python.org/issue36347
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-1/+1
