I searched for "_PyGC_FINALIZED" in top 5000 PyPI projects. It seems like only
Cython is impacted.
ddtrace and guppy3 use directly the internal C API.
== Cython 0.29.26 ==
* Cython/Compiler/ModuleNode.py: finalised_check = '!_PyGC_FINALIZED(o)'
* Cython/Compiler/ModuleNode.py: '(!PyType_IS_GC(Py_TYPE(o)) ||
!_PyGC_FINALIZED(o))')
== ddtrace 0.57.3 ==
In ddtrace/profiling/collector/stack.pyx:
IF PY_MINOR_VERSION >= 9:
# Needed for accessing _PyGC_FINALIZED when we build with
-DPy_BUILD_CORE
cdef extern from "<internal/pycore_gc.h>":
pass
== guppy3-3.1.2 ==
In src/heapy/hv.c:
#if PY_MAJOR_VERSION >= 3 && PY_MINOR_VERSION >= 9
# define Py_BUILD_CORE
/* PyGC_Head */
# undef _PyGC_FINALIZED
# include <internal/pycore_gc.h>
# undef Py_BUILD_CORE
#endif
