* gh-94673: Ensure Builtin Static Types are Readied Properly (gh-103940)Eric Snow2023-04-271-2/+2
| | | There were cases where we do unnecessary work for builtin static types. This also simplifies some work necessary for a per-interpreter GIL.
* gh-99537: Use Py_SETREF(var, NULL) in C code (#99687)Victor Stinner2022-11-231-4/+2
| | | Replace "Py_DECREF(var); var = NULL;" with "Py_SETREF(var, NULL);".
* gh-99300: Use Py_NewRef() in Objects/ directory (#99332)Victor Stinner2022-11-101-16/+8
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in C files of the Objects/ directory.

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-45439: Move _PyObject_VectorcallTstate() to pycore_call.h (GH-28893)Victor Stinner2021-10-141-0/+1
| | | | | | | | | | | * Move _PyObject_VectorcallTstate() and _PyObject_FastCallTstate() to pycore_call.h (internal C API). * Convert PyObject_CallOneArg(), PyObject_Vectorcall(), _PyObject_FastCall() and PyVectorcall_Function() static inline functions to regular functions. * Add _PyVectorcall_FunctionInline() static inline function. * PyObject_Vectorcall(), _PyObject_FastCall(), and PyObject_CallOneArg() now call _PyThreadState_GET() rather than PyThreadState_Get().

* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-2/+2
| | | | | | 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 Demeyer2020-02-181-3/+3
| | | | | | | | 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

| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* bpo-37340: Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() ↵Victor Stinner2019-11-201-14/+0
| | | | | | | | (GH-17284) Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() functions: the free lists of bound method objects have been removed. Remove also _PyMethod_Fini() and _PyCFunction_Fini() functions.
* bpo-38644: Add _PyObject_VectorcallTstate() (GH-17052)Victor Stinner2019-11-081-7/+12
| | | | | * Add _PyObject_VectorcallTstate() function: similar to _PyObject_Vectorcall(), but with tstate parameter * Add tstate parameter to _PyObject_MakeTpCall()
* Make PyXXX_Fini() functions private (GH-15531)Victor Stinner2019-08-261-1/+1
| | | | | For example, rename PyTuple_Fini() to _PyTuple_Fini(). These functions are only declared in the internal C API.

* closes bpo-36188: Clean up 'unbound' method left-overs. (GH-12169)Martijn Pieters2019-03-051-18/+3
| | | | | | | | | | Methods are always bound, and `__self__` can no longer be `NULL` (`method_new()` and `PyMethod_New()` both explicitly check for this). Moreover, once a bound method is bound, it *stays* bound and won't be re-bound to something else, so the section in the datamodel that talks about accessing an methods in a different descriptor-binding context doesn't apply any more in Python 3.
* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-5/+2
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-35059: PyObject_INIT() casts to PyObject* (GH-10674)Victor Stinner2018-11-231-1/+1
| | | | | | PyObject_INIT() and PyObject_INIT_VAR() now cast their first argument to PyObject*, as done in Python 3.7. Revert partially commit b4435e20a92af474f117b78b98ddc6f515363af5.

* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-2/+2
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".

| | | | | * Convert PyObject_INIT() and PyObject_INIT_VAR() macros to static inline functions. * Fix usage of these functions: cast to PyObject* or PyVarObject*.

| | | | | | | | | | | value of self. (GH-7848) * The hash of BuiltinMethodType instances no longer depends on the hash of __self__. It depends now on the hash of id(__self__). * The hash and equality of ModuleType and MethodWrapperType instances no longer depend on the hash and equality of __self__. They depend now on the hash and equality of id(__self__). * MethodWrapperType instances no longer support ordering.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

| | | | | | | Issue #27841: Add _PyObject_Call_Prepend() helper function to prepend an argument to existing arguments to call a function. This helper uses fast calls. Modify method_call() and slot_tp_new() to use _PyObject_Call_Prepend().
