ilistdir of ROMFS returns tuple of 3 elements

[bixb922]

When doing os.ilistdir("/") and ROMFS is enabled the result is :

>>> [ i for i in os.ilistdir(path)]
[('rom', 16384, 0), ('data', 16384, 0, 0), ('lib', 16384, 0, 0), ('main.py', 32768, 0, 2210), ('signals', 16384, 0, 0), ('software', 16384, 0, 0), ('tunelib', 16384, 0, 0)]

All files return a tuple of 4 elements, except the rom folder of ROMFS. This breaks existing code that checks for the size.

MicroPython version:

MPY: soft reboot
MicroPython v1.26.0-preview.226.g5676b45cb.dirty on 2025-06-12; Generic ESP32S3 module with Octal-SPIRAM with ESP32S3

However, extmod/vfs_rom.c seems to return 4 element tuples, with a code similar to ext_mod/vfs_lfsx.c:

// Make 4-tuple with info about this entry: (name, attr, inode, size)
        mp_obj_tuple_t *t = MP_OBJ_TO_PTR(mp_obj_new_tuple(4, NULL));

        if (self->is_str) {
            t->items[0] = mp_obj_new_str((const char *)name_str, name_len);
        } else {
            t->items[0] = mp_obj_new_bytes(name_str, name_len);
        }

        t->items[1] = MP_OBJ_NEW_SMALL_INT(type);
        t->items[2] = MP_OBJ_NEW_SMALL_INT(0);
        t->items[3] = mp_obj_new_int(data_len);

        return MP_OBJ_FROM_PTR(t);
    }

This is unexpected. Before reporting as bug, I'd like some confirmation.

I replaced this with an issue.
