| | | | | | | | | | | | | | | | 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. It's no longer needed.
* Split refcount stats into 'interpreter' and 'non-interpreter' (GH-92919)Mark Shannon2022-05-181-0/+2

| | | | | | | generator. (GH-29891) * Make generator, coroutine and async gen structs all the same size. * Store interpreter frame in generator (and coroutine). Reduces the number of allocations neeeded for a generator from two to one.

* bpo-44525: Copy free variables in bytecode to allow calls to inner functions ↵Mark Shannon2021-11-231-4/+2
| | | | | | | | | | | 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.
* bpo-45813: Make sure that frame->generator is NULLed when generator is ↵Mark Shannon2021-11-221-0/+3
| | | | deallocated. (GH-29700)
* bpo-44990: Change layout of evaluation frames. "Layout B" (GH-27933)Mark Shannon2021-08-251-20/+12
| | | Places the locals between the specials and stack. This is the more "natural" layout for a C struct, makes the code simpler and gives a slight speedup (~1%)
* bpo-44590: Lazily allocate frame objects (GH-27077)Mark Shannon2021-07-261-0/+135
* Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it. * Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector. * Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation. * Move ownership of InterpreterFrame in generator from frame object to generator object. * Do not create frame objects for Python calls. * Do not create frame objects for generators.
