- `_Py_EncodeLocaleRaw`, which is private by name, undocumented,
and wasn't exported in `python3.dll`, is moved to a private header.
- `_Py_HashSecret_Initialized`, again private by name, undocumented,
and not exported in `python3.dll`, is excluded with `Py_LIMITED_API`.
- `PyMarshal_*` and `PyMember_*One` functions, declared in private headers and
not exported in `python3.dll`, are removed from `Doc/data/stable_abi.dat`.
- `PyMem_Calloc` which *was* exported in `python3dll.c`, is moved to public
headers where it joins its other `PyMem_*` friends.
Only the last change is documented in the blurb; others are not user-visible.
(Nothing uses `Doc/data/stable_abi.dat` yet.)
https://bugs.python.org/issue43795
Add the Py_Is(x, y) function to test if the 'x' object is the 'y'
object, the same as "x is y" in Python. Add also the Py_IsNone(),
Py_IsTrue(), Py_IsFalse() functions to test if an object is,
respectively, the None singleton, the True singleton or the False
singleton.
The stable_abi.py script no longer parse macros. Macro targets can be
static inline functions which are not part of the stable ABI, only
part of the limited C API.
Run "make regen-limited-abi" to exclude PyType_HasFeature from
Doc/data/stable_abi.dat.
Rename Include/symtable.h to to Include/internal/pycore_symtable.h,
don't export symbols anymore (replace PyAPI_FUNC and PyAPI_DATA with
extern) and rename functions:
* PyST_GetScope() to _PyST_GetScope()
* PySymtable_BuildObject() to _PySymtable_Build()
* PySymtable_Free() to _PySymtable_Free()
Remove PySymtable_Build(), Py_SymtableString() and
Py_SymtableStringObject() functions.
The Py_SymtableString() function was part the stable ABI by mistake
but it could not be used, since the symtable.h header file was
excluded from the limited C API.
The Python symtable module remains available and is unchanged.
