Subject: Re: [E-devel] [Elc_Naviframe]: Crash on evas_object_del fix.
Hi,
This crash happens if pop_transition_cb gets scheduled first but transition is
not completed and before that itself evas_object_del
is called, with below code it might be hard to reproduce, as per below code
pop_transition_cb will not
even get a chance to get scheduled.
so to reproduce this crash you can call item_pop in some button click callback
and then call evas_object_del in a timer callback and give time gap of 0.3
seconds. when you do this
pop_transition_cb gets called first, then evas_object_del before animation is
complete and hence the crash can be reproduced.
I have got this crash with various apps which I am testing here on target (as
they have their own cleanup code before calling del the above scenario was
created almost everywhere)
and logically if you check the item pointer from sd->popping list needs
to be removed only after pop operation is complete. instead its being done in
pop_transition_cb which begins the animation.
Thanks & Regards
Shilpa Singh

Dear Shilpa,
it doesn't crash here.
Do you have any reproducable code?
I tried with the following code.
--- a/elementary/src/bin/test_naviframe.c
+++ b/elementary/src/bin/test_naviframe.c
@@ -190,6 +190,10 @@ _page2(void *data, Evas_Object *obj __UNUSED__, void
*event_info __UNUSED__)
Evas_Object *bt, *content, *ic, *nf = data;
Elm_Object_Item *it;
+elm_naviframe_item_pop(data);
+evas_object_del(data);
+return;
+
bt = elm_button_add(nf);
evas_object_size_hint_align_set(bt, EVAS_HINT_FILL, EVAS_HINT_FILL);
evas_object_smart_callback_add(bt, "clicked", _page3, nf);
