Comment (by nickm): I'm guessing that clientmap_entry_size() is something we'd extend once we have this and #24902 merged to the same branch? The geoip_client_cache_total_allocation() function needs to be much faster -- otherwise it will eat tons of CPU by walking the whole map every time cell_queues_check_size() is called -- and it is called from inside append_cell_to_circuit_queue(). How about having a static size_t that we increment when we allocate an entry, and decrement when we free it? Otherwise, looks plausible. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/25122#comment:2> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
