Request for PyModule_GetModuleByDef()

Core Development
1

In moving my code to use module states I have the need to obtain the module object for the “current” module. All I have in the way of context is the PyModuleSpec structure for the module. The following should work (no error checking)…

PyObject *PyModule_GetModuleByDef(struct PyModuleDef *target_def)
{
    PyObject *modules = PySys_GetAttrString(“modules”);

    Py_ssize_t pos;
    PyObject *name, *module;

    while (PyDict_Next(modules, &pos, &name, &module))
    {
        struct PyModuleDef *module_def;

        PyModule_GetToken(module, &module_def);

        if (module_def == target_def)
        {
            Py_DECREF(modules);
            return module;
        }
    }

    Py_DECREF(modules);

    return NULL;
}

…but is there any chance of this being implemented in the stable ABI (and made more efficient of course)?

…and that should have been PyModule_GetModuleByToken(void *mod_token).
