    * Increased the default minimum tunnel test time to 5 seconds, since we
      still see the occational message processing time spike to 2 seconds.
    * Update the SimpleTimer to allow rescheduling a task thats already
      queued (useful for the new streaming lib).

jrandom authored 20 years ago and zzz committed 20 years ago

    * Replaced old minimum tunnel test timeout of 1s with a configurable
      value (router.config property "router.tunnelTestMinimum", with the
      default of 2s).

    * Tunnel rejection is no longer a sign of an overwhelmingly loaded
      peer, so don't use it as a key point of the IsFailing calculator.
      We still use it as a key point of the Capacity calculator, however.

    * Allow for a configurable tunnel "growth factor", rather than trying
      to achieve a steady state.  This will let us grow gradually when
      the router is needed more, rather than blindly accepting the request
      or arbitrarily choking it at an averaged value.  Configure this with
      "router.tunnelGrowthFactor" in the router.config (default "1.5").
    * Adjust the tunnel test timeouts dynamically - rather than the old
      flat 30s (!!!) timeout, we set the timeout to 2x the average tunnel
      test time (the deviation factor can be adjusted by setting
      "router.tunnelTestDeviation" to "3.0" or whatever).  This should help
      find the 'good' tunnels.
    * Added some crazy debugging to try and track down an intermittent hang.

    * Fix the probabalistic tunnel reject (we always accepted everything,
      since the docs on java.util.Random.nextDouble() are wrong..)
    * Fixed a race on startup (thanks Quadn!)

    * Disable the probabalistic drop by default (enable via the router config
      property "tcp.dropProbabalistically=true")
    * Disable the actual watchdog shutdown by default, but keep track of more
      variables and log a lot more when it occurs (enable via the router
      config property "watchdog.haltOnHang=true")
    * Implement some tunnel participation smoothing by refusing requests
      probabalistically as our participating tunnel count exceeds the previous
      hour's, or when the 10 minute average tunnel test time exceeds the 60
      minute average tunnel test time.  The probabilities in both cases are
      oldAverage / #current, so if you're suddenly flooded with 200 tunnels
      and you had previously only participated in 50, you'll have a 25% chance
      of accepting a subsequent request.

    * Update the I2PTunnel HTTP proxy to strip out the i2paddresshelper from
      the request.

    * Added a watchdog timer to do some baseline liveliness checking to help
      debug some odd errors.
    * Added a pair of summary stats for bandwidth usage, allowing easy export
      with the other stats ("bw.sendBps" and "bw.receiveBps")
    * Trimmed another memory allocation on message reception.

    * Revamp the AESInputStream so it doesn't allocate any temporary objects
      during its operation.

    * Don't kill the establisher threads during a soft restart.
    * Attempt to validate the peer's routerInfo earlier during handshaking.
    * Revamp the AESOutputStream so it doesn't allocate any temporary objects
      during its operation.

    * Reimplement the I2NP reading with less temporary memory allocation.
      There is still significant GC churn, especially under load, but this
      should help.
    * Catch some oddball errors in the transport (message timeout while
      establishing).

jrandom authored 20 years ago and zzz committed 20 years ago

    * Expire queued messages even when the writer is blocked.
    * Reimplement most of the I2NP writing with less temporary memory
      allocations (I2NP reading still gobbles memory).

    * Implement an active queue management scheme on the TCP transports,
      dropping messages probabalistically as the queue fills up.  The
      estimated queue capacity is determined by the rate at which messages
      have been sent to the peer (averaged at 1, 5, and 60m periods).  As
      we exceed 1/2 of the estimated capacity, we drop messages throughout
      the queue probabalistically with regards to their size.  This is based
      on RFC 2309's RED, with the minimum threshold set to 1/2 the
      estimated connection capacity.  We may want to consider using a send
      rate and queue size measured across all connections, to deal with our
      own local bandwidth saturation, but we'll try the per-con metrics first.

    * Enable explicit disabling of the systray entirely for windows machines
      with strange configurations: add -Dsystray.disable=true to the java
      command line.  (thanks mihi!)

    * Allow peers on the same LAN to communicate with each other safely even
      when they cannot talk to each other through the external address.

    * Display how much time is left before the graceful shutdown is complete.
    * Debug some improperly failed messages on timeout or disconnection.

    * Don't go into a fast busy if an I2PTunnel 'server' is explicitly killed
      (thanks mule!)
    * Handle some more error conditions regarding abruptly closing sockets
      (thanks Jonva!)

    * Update the shitlist to reject a peer for an exponentially increasing
      period of time (with an upper bounds of an hour).
    * Various minor stat and debugging fixes
