  has session tags within it, send an additional ping to the peer,
  bundling those tags a second time, ACKing those tags on the pong.
* handle packets transferred during a race after the receiver ACKs the
  connection but before the establisher receives the ACK.
* notify the messageInputStream reader on close (duh)
* new stream sink test, shoving lots and lots of data down a stream
  with the existing StreamSinkServer and StreamSinkClient apps
* logging

    * Allow explicit inclusion of session tags in the SDK, enabling the
      resending of tags bundled with messages that would not otherwise
      be ACKed.
    * Don't force mode=guaranteed for end to end delivery - if mode=bestEffort
      no DeliveryStatusMessage will be bundled (and as such, client apps using
      it will need to do their own session tag ack/nack).
    * Handle client errors when notifying them of message availability.
    * New StreamSinkSend which sends a file to a destination and disconnects.
    * Update the I2PSocketManagerFactory to build the specific
      I2PSocketManager instance based on the "i2p.streaming.manager" property,
      containing the class name of the I2PSocketManager implementation to instantiate.

* deal with window size > 1, especially before receiving the first ACK
* disable congestion control for the moment (aka unlimited window size)

    * Minor ministreaming lib refactoring to simplify integration of the full
      streaming lib.
    * Minor bugfixes to data structure serialization.

very basic tests pass (ping, open then pause then close, open then echo back and forth a few times then close)

    * Allow sending messages with a section of a byte array.
    * Reduced stats published.

    * Don't b0rk on whitespace in the router address.

    * More aggressively reduce the capacity of peers if their tunnels are
      failing so that we move off them quicker.

jrandom authored 20 years ago and zzz committed 20 years ago

    * More aggressively fail peers if their tunnels are failing so that we
      move off them quicker.
    * Simplify some data structure serialization for reuse in the streaming
      lib, as well as add support for signing and verifying partial byte
      arrays.
    * Logging updates

packet spec is at a save point)

    * 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).

jrandom authored 20 years ago and zzz committed 20 years ago

    * 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.

jrandom authored 20 years ago and zzz committed 20 years ago

    * 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.

jrandom authored 20 years ago and zzz committed 20 years ago

    * 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!)

jrandom authored 20 years ago and zzz committed 20 years ago

    * 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.

jrandom authored 20 years ago and zzz committed 20 years ago

    * 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.

jrandom authored 20 years ago and zzz committed 20 years ago

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

jrandom authored 20 years ago and zzz committed 20 years ago

    * 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.

jrandom authored 20 years ago and zzz committed 20 years ago

    * 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).
