Bug report
Bug description:
#include <Python.h>
static int
examplemodule_exec(PyObject *module) {
// Yes I know there's no error checking...
PyObject *gil_enabled = PySys_GetObject("_is_gil_enabled");
PyObject *result = PyObject_CallNoArgs(gil_enabled);
printf("gil enabled: ");
PyObject_Print(result, stdout, 0);
printf("\n");
Py_DECREF(result);
return 0;
}
static PyModuleDef_Slot examplemodule_slots[] = {
{Py_mod_name, "examplemodule"},
{Py_mod_gil, Py_MOD_GIL_USED},
{Py_mod_exec, (void*)examplemodule_exec},
{0}
};
PyMODEXPORT_FUNC
PyModExport_examplemodule(void)
{
return examplemodule_slots;
}I believe that the code above should print "gil enabled: True". However when I run it on Python 3.15.0a2 freethreading it prints "gil enabled: False".
I don't believe this is an issue in the old style PyInit_ initialization.
