Py_REFCNT(), Py_TYPE(), Py_SIZE() and Py_IS_TYPE() functions argument
type is now "PyObject*", rather than "const PyObject*".
* Replace also "const PyObject*" with "PyObject*" in functions:
* _Py_strhex_impl()
* _Py_strhex_with_sep()
* _Py_strhex_bytes_with_sep()
* Remove _PyObject_CAST_CONST() and _PyVarObject_CAST_CONST() macros.
* Py_IS_TYPE() can now use Py_TYPE() in its implementation.
* Stores all location info in linetable to conform to PEP 626.
* Remove column table from code objects.
* Remove end-line table from code objects.
* Document new location table format
* Revert "bpo-46850: Move _PyInterpreterState_SetEvalFrameFunc() to internal C API (GH-32054)"
This reverts commit f877b40e3f.
* Revert "bpo-46850: Move _PyEval_EvalFrameDefault() to internal C API (GH-32052)"
This reverts commit b9a5522dd9.
The fact interpreter frames were split out from full frame objects
rather than always being part of the eval loop implementation means
that it's tricky to infer the expected naming conventions simply
from looking at the code.
Documenting the de facto conventions in pycore_frame.h means future
readers of the code will have a clear explanation of the rationale
for those conventions (i.e. minimising non-functional code churn).
Move the private _PyFrameEvalFunction type, and private
_PyInterpreterState_GetEvalFrameFunc() and
_PyInterpreterState_SetEvalFrameFunc() functions to the internal C
API. The _PyFrameEvalFunction callback function type now uses the
_PyInterpreterFrame type which is part of the internal C API.
Update the _PyFrameEvalFunction documentation.
Move the private undocumented _PyEval_EvalFrameDefault() function to
the internal C API. The function now uses the _PyInterpreterFrame
type which is part of the internal C API.
* `PyFrame_FastToLocalsWithError` and `PyFrame_LocalsToFast` are no longer called during profile and tracing.
(Contributed by Fabio Zadrozny)
* Make accesses to a frame's `f_locals` safe from C code, not relying on calls to `PyFrame_FastToLocals` or `PyFrame_LocalsToFast`.
* Document new `PyFrame_GetLocals` C-API function.
In a gh-32003 comment, I realized it wasn't very clear how _Py_DECLARE_STR() should be used. This changes adds a comment to clarify.

* Moves the bytecode to the end of the corresponding PyCodeObject, and quickens it in-place.
* Removes the almost-always-unused co_varnames, co_freevars, and co_cellvars member caches
* _PyOpcode_Deopt is a new mapping from all opcodes to their un-quickened forms.
* _PyOpcode_InlineCacheEntries is renamed to _PyOpcode_Caches
* _Py_IncrementCountAndMaybeQuicken is renamed to _PyCode_Warmup
* _Py_Quicken is renamed to _PyCode_Quicken
* _co_quickened is renamed to _co_code_adaptive (and is now a read-only memoryview).
* Do not emit unused nonzero opargs anymore in the compiler.
Remove the private undocumented function
_PyEval_GetCoroutineOriginTrackingDepth() from the C API. Call the
public sys.get_coroutine_origin_tracking_depth() function instead.
Change the internal function
_PyEval_SetCoroutineOriginTrackingDepth():
* Remove the 'tstate' parameter;
* Add return value and raises an exception if depth is negative;
* No longer export the function: call the public
sys.set_coroutine_origin_tracking_depth() function instead.
Uniformize also function declarations in pycore_ceval.h.
Remove the following private undocumented functions from the C API:
* _PyEval_GetAsyncGenFirstiter()
* _PyEval_GetAsyncGenFinalizer()
* _PyEval_SetAsyncGenFirstiter()
* _PyEval_SetAsyncGenFinalizer()
Call the public sys.get_asyncgen_hooks() and sys.set_asyncgen_hooks()
functions instead.
Add new functions to pack and unpack C double (serialize and
deserialize):
* PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8()
* PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8()
Document these functions and add unit tests.
Rename private functions and move them from the internal C API
to the public C API:
* _PyFloat_Pack2() => PyFloat_Pack2()
* _PyFloat_Pack4() => PyFloat_Pack4()
* _PyFloat_Pack8() => PyFloat_Pack8()
* _PyFloat_Unpack2() => PyFloat_Unpack2()
* _PyFloat_Unpack4() => PyFloat_Unpack4()
* _PyFloat_Unpack8() => PyFloat_Unpack8()
Replace the "unsigned char*" type with "char*" which is more common
and easy to use.
Add methods __typing_subst__() in TypeVar and ParamSpec.
Simplify code by using more object-oriented approach, especially
the C code for types.GenericAlias and the Python code for
collections.abc.Callable.
Rename also struct _cframe to struct _PyCFrame.
Add a comment suggesting using public functions rather than using
directly the private _PyCFrame structure.
