[E-devel] Eo del/unref question

[Davide A. <da...@gu...>]

Hi all,
I'm working/studying Eo while trying to optimize the python bindings
and I have some problems deleting eo objects.

see this super simple example:
(pastebin.com/1C0dqdYA for a "colored" version)


#include <Eo.h>
#include <Elementary.h>

void
my_win_del(void *data, Evas_Object *obj, void *event_info)
{
   elm_exit();
}

EAPI_MAIN int
elm_main(int argc, char **argv)
{
    Evas_Object *win, *r;

    win = elm_win_add(NULL, "main", ELM_WIN_BASIC);
    elm_win_title_set(win, "Elementary Tests");
    evas_object_smart_callback_add(win, "delete,request", my_win_del, NULL);
    evas_object_resize(win, 320, 320);
    evas_object_show(win);

    r = evas_object_rectangle_add(evas_object_evas_get(win));
    evas_object_resize(r, 100, 100);
    evas_object_show(r);

    evas_object_del(r); // this one work as expected
    // eo_del(r);               // this give a bad warnig
    // eo_unref(r);            // this cause an endless loop on elm_shutdown

    elm_run();
    elm_shutdown();

    return 0;
}

ELM_MAIN()



The example simply create a rectangle and then delete it, the only working
way to delete the rect
seems to be the evas_object_del call (that work as expected)

Using eo_del() to delete the rect cause this warning:
ERR<3219>:eo lib/eo/eo.c:1306 _eo_unref() Object 0x21d9920 already deleted.
ERR<3219>:eo lib/eo/eo.c:1306 _eo_unref() Object 0x21d9920 already deleted.
as soon as you call eo_del()

While eo_unref() cause an endless loop on elm_shutdown with this warning
repeated forever:
CRI<3242>: lib/eo/eo.c:1081 eo_parent_set() *** Eina Magic Check Failed at
0x1a88f80 !!!
    Input handle is wrong type
    Expected: a186bc32 - Eo
    Supplied: afda6798 - (unknown)

I'm doing something wrong? I'm misunderstanding something?

any help is appreciated

thanks
