* Revert "bpo-44800: Document internal frame naming conventions (GH-32281)" ↵Mark Shannon2022-04-041-69/+0
| | | | | (#32301) This reverts commit 124227c95f310d2ecd4b567271ab1919fc7000cb.

* bpo-44800: Document internal frame naming conventions (GH-32281)Nick Coghlan2022-04-031-0/+69
| | | | | | | | | | 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).
* bpo-47186: Replace JUMP_IF_NOT_EXC_MATCH by CHECK_EXC_MATCH + jump (GH-32231)Irit Katriel2022-04-011-36/+36

* bpo-46850: Move _PyInterpreterState_SetEvalFrameFunc() to internal C API ↵Victor Stinner2022-04-013-12/+16
| | | | | | | | | | | (GH-32054) 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.
* bpo-46850: Move _PyEval_EvalFrameDefault() to internal C API (GH-32052)Victor Stinner2022-04-012-2/+5
| | | | | 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.

* bpo-47164: Add _PyCFunctionObject_CAST() macr (GH-32190)Victor Stinner2022-03-311-6/+11
| | | | | | | | Add _PyCFunctionObject_CAST() and _PyCMethodObject_CAST() macros to make macros casting their argument easier to read, but also to check the type of their input in debug mode: assert(PyCFunction_Check(func) and assert(PyCMethod_Check(func). Reformat also PyCFunction_XXX() macros for readability.
* bpo-47164: Add _PyCFunction_CAST() macro (GH-32192)Victor Stinner2022-03-311-0/+18
| | | Use the macro in C files of the Python/ directory.
* bpo-47164: Add _PyASCIIObject_CAST() macro (GH-32191)Victor Stinner2022-03-312-34/+35
| | | | | | | | | | | | Add macros to cast objects to PyASCIIObject*, PyCompactUnicodeObject* and PyUnicodeObject*: _PyASCIIObject_CAST(), _PyCompactUnicodeObject_CAST() and _PyUnicodeObject_CAST(). Using these new macros make the code more readable and check their argument with: assert(PyUnicode_Check(op)). Remove redundant assert(PyUnicode_Check(op)) in macros using directly or indirectly these new CAST macros. Replacing existing casts with these macros.

| | | | | | | | | | | (GH-32055) * `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.
