Class TrackerClient

  • All Implemented Interfaces:

    public class TrackerClient
    extends Object
    implements Runnable
    Informs metainfo tracker of events and gets new peers for peer coordinator. start() creates a thread and starts it. At the end of each run, a TimedEvent is queued on the SimpleTimer2 queue. The TimedEvent creates a new thread and starts it, so it does not clog SimpleTimer2. The thread runs one pass through the trackers, the PEX, and the DHT, then queues a new TimedEvent and exits. Thus there are only threads that are actively announcing, not one thread per torrent forever. start() may be called again after halt().

      • start

        public void start()
      • halted

        public boolean halted()
      • started

        public boolean started()
      • halt

        public void halt​(boolean fast)
        Interrupts this Thread to stop it.
        fast - if true, limit the life of the unannounce threads
      • run

        public void run()
        Setup the first time only, then one pass (usually) through the trackers, PEX, and DHT. This will take several seconds to several minutes.
        Specified by:
        run in interface Runnable
      • urlencode

        public static String urlencode​(byte[] bs)
        Very lazy byte[] to URL encoder. Just encodes almost everything, even some "normal" chars. By not encoding about 1/4 of the chars, we make random data like hashes about 16% smaller. RFC1738: 0-9a-zA-Z$-_.+!*'(), Us: 0-9a-zA-Z
      • isValidAnnounce

        public static boolean isValidAnnounce​(String ann)
        ann - an announce URL, may be null, returns false if null
        true for i2p hosts only
