* gh-94673: Recover Weaklist Lookup Performance (gh-95544)Eric Snow2022-08-041-0/+33
| | | gh-95302 seems to have introduced a small performance regression. Here we make some minor changes to recover that lost performance.

* gh-94673: Add Per-Interpreter Storage for Static Builtin Types (#95255)Eric Snow2022-07-263-1/+18
| | | | | | | | | | | | | | This is the last precursor to storing tp_subclasses (and tp_weaklist) on the interpreter state for static builtin types. Here we add per-type storage on PyInterpreterState, but only for the static builtin types. This involves the following: * add PyInterpreterState.types * move PyInterpreterState.type_cache to it * add a "num_builtins_initialized" field * add a "builtins" field (a static array big enough for all the static builtin types) * add _PyStaticType_GetState() to look up a static builtin type's state * (temporarily) add PyTypeObject.tp_static_builtin_index (to hold the type's index into PyInterpreterState.types.builtins) We will be eliminating tp_static_builtin_index in a later change.
* gh-91247: Use memcpy for list and tuple repeat (#91482)Pieter Eendebak2022-07-262-0/+23
| | | | | | | * Add _Py_memory_repeat function to pycore_list * Add _Py_RefcntAdd function to pycore_object * Use the new functions in tuplerepeat, list_repeat, and list_inplace_repeat

* gh-94673: Add _PyStaticType_InitBuiltin() (#95152)Eric Snow2022-07-253-1/+12
| | | | | | | | | | | | This is the first of several precursors to storing tp_subclasses (and tp_weaklist) on the interpreter state for static builtin types. We do the following: * add `_PyStaticType_InitBuiltin()` * add `_Py_TPFLAGS_STATIC_BUILTIN` * set it on all static builtin types in `_PyStaticType_InitBuiltin()` * shuffle some code around to be able to use _PyStaticType_InitBuiltin() * rename `_PyStructSequence_InitType()` to `_PyStructSequence_InitBuiltinWithFlags()` * add `_PyStructSequence_InitBuiltin()`.

| | | | | | | | | | | | | | | | Move the follow functions and type from frameobject.h to pyframe.h, so the standard <Python.h> provide frame getter functions: * PyFrame_Check() * PyFrame_GetBack() * PyFrame_GetBuiltins() * PyFrame_GetGenerator() * PyFrame_GetGlobals() * PyFrame_GetLasti() * PyFrame_GetLocals() * PyFrame_Type Remove #include "frameobject.h" from many C files.

* gh-93442: Make C++ version of _Py_CAST work with 0/NULL. (#93500)Neil Schemenauer2022-06-051-0/+14
| | | | | | | | | | | | Add C++ overloads for _Py_CAST_impl() to handle 0/NULL. This will allow C++ extensions that pass 0 or NULL to macros using _Py_CAST() to continue to compile. Without this, you get an error like: invalid ‘static_cast’ from type ‘int’ to type ‘_object*’ The modern way to use a NULL value in C++ is to use nullptr. However, we want to not break extensions that do things the old way. Co-authored-by: serge-sans-paille
