In case of normal fetch, the .recursionquota is attached and ns_statscounter_recursclients is incremented when the fetch is created. Then the .recursionquota is detached and the counter decremented in the fetch_callback(). In case of prefetch or rpzfetch, the quota is attached, but the counter is not incremented. When we reach the soft-quota, the function returns early but don't detach from the quota, and it gets destroyed during the ns_client_endrequest(), so no memory was leaked. But because the ns_statscounter_recursclients is only incremented during the normal fetch the counter would be incorrectly decremented on two occassions: 1) When we reached the softquota, because the quota was not properly detached 2) When the prefetch or rpzfetch was cancelled mid-flight and the callback function was never called. |
