* gh-123923: Defer refcounting for `f_funcobj` in `_PyInterpreterFrame` (#124026)Sam Gross2024-09-241-32/+19
| | | | | | Use a `_PyStackRef` and defer the reference to `f_funcobj` when possible. This avoids some reference count contention in the common case of executing the same code object from multiple threads concurrently in the free-threaded build.

* gh-117139: Replace _PyList_FromArraySteal with stack ref variant (#122830)Sam Gross2024-08-121-9/+1
| | | | | | | This replaces `_PyList_FromArraySteal` with `_PyList_FromStackRefSteal`. It's functionally equivalent, but takes a `_PyStackRef` array instead of an array of `PyObject` pointers. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-117139: Fix a few `_PyStackRef` related bugs (#122831)Sam Gross2024-08-121-3/+2
| | | | | | `BUILD_SET` should use a borrow instead of a steal. The cleanup in `_DO_CALL` `CONVERSION_FAILED` was incorrect. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-118926: Spill deferred references to stack in cases generator (#122748)Sam Gross2024-08-071-17/+17
| | | | | | | This automatically spills the results from `_PyStackRef_FromPyObjectNew` to the in-memory stack so that the deferred references are visible to the GC before we make any possibly escaping call. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-117139: Fix an incorrect borrow in bytecodes.c (#122318)Sam Gross2024-08-071-4/+5
| | | `_PyDict_SetItem_Take2` steals both the key (i.e., `sub`) and the value.

* gh-117139: Convert the evaluation stack to stack refs (#118450)Ken Jin2024-06-261-1211/+1550
| | | | | | | | | | | | | | | | | This PR sets up tagged pointers for CPython. The general idea is to create a separate struct _PyStackRef for everything on the evaluation stack to store the bits. This forces the C compiler to warn us if we try to cast things or pull things out of the struct directly. Only for free threading: We tag the low bit if something is deferred - that means we skip incref and decref operations on it. This behavior may change in the future if Mark's plans to defer all objects in the interpreter loop pans out. This implies a strict stack reference discipline is required. ALL incref and decref operations on stackrefs must use the stackref variants. It is unsafe to untag something then do normal incref/decref ops on it. The new incref and decref variants are called dup and close. They mimic a "handle" API operating on these stackrefs. Please read Include/internal/pycore_stackref.h for more information! --------- Co-authored-by: Mark Shannon <9448417+markshannon@users.noreply.github.com>
