Subject: Re: [E-devel] [Patch] ecore_ipc - remove potential risk in
ecore_ipc_shutdown
I found a problem this infinite loop case.
If server is deleted, then ECORE_IPC_EVENT_SERVER_DEL callback
function will be called in client side.
It will happen infinite loop in ecore_ipc_shutdown if
ecore_ipc_shutdown called in this ECORE_IPC_EVENT_SERVER_DEL callback
function.
For example,
server_del_handler =
ecore_event_handler_add(ECORE_IPC_EVENT_SERVER_DEL, _server_del_cb, NULL);
static Eina_Bool
_server_del_cb(void *data, int type, void *event)
{
ecore_ipc_shutdown();
return EINA_TRUE;
}
If server is deleted,
1. _ecore_ipc_event_server_del : svr->event_count++
2. _server_del_cb : ecore_ipc_shutdown called
3. ecore_ipc_shutdown : while (servers) ecore_ipc_server_del(eina_list_data_get(servers))
4. ecore_ipc_server_del : can't eina_list_remove(servers, svr) because event_count != 0
5. infinite loop
I think this while code is very dangerous whether user miss or not.
I modified EINA_LIST_FOREACH_SAFE instead of EINA_LIST_FOREACH refer
to ecore_con.
Please review this patch.
