2b21b97277 * make sure we send the close message even if the I2PSocket is closed directly (rather than the outputStream)
* only fail the session tags as a last resort for the last resend, rather than on every resend after the 1st

426ede1c99 * handle con b0rkage more gracefully
* close the session on socket manager destroy (the old lib does, and SAM wants it to)

ed8eced9dd * stats
if you want to get this data and you're running outside the router, just toss on a
"-Dstat.logFilters=* -Dstat.logFile=proxy.stats" to the java command line.  the resulting
file can be parsed w/ java -cp lib/i2p.jar net.i2p.stat.StatLogSplitter proxy.stats, then fed
into gnuplot or whatever

4a029b7853 * if we timeout connecting or otherwise need to cancel tags that we've sent, go one step
further and cancel all of the tags we're using for that peer so that we can react to their
  potential restart / tag loss quicker.
* use the minimum resend delay as the base to be exponentiated if our RTT is too low
  (so we resend less)
* dont be such a wuss when flushing a closed stream

f46d0a720c * fix up the propogation of client options to the streaming lib
* add new back-off logic to reduce payload resends during transient
  lag - only let one packet be resent at a time, even if the window size
  allows it (and the packet timers request it).  this should make
  congestion less painful, and reduce the overall number of messages
  resent (as the SACKs for the one packet actively resent should clarify
  what made it through)

73a12d47de * you mean we should implement congestion *avoidance* too?

83165df7e5 * delay the ack of a syn
* make sure we ack duplicate messages received (if we aren't already doing so)

  explicit congestion notification)

9ea603caf2 * hang around for 5m (er, 2.5msl, i suppose) after connection closure no matter what, so we
can respond apropriately
* optional inactivty timer with three possible results:
  disconnect, send a (blank) message (to be ACKed), or do nothing.

2486e5e75f on some resends, drop our session tags for the peer and revert to ElGamal, since
they may have restarted or otherwise lost the tags delivered to them.

* Fix for a long standing synchronization bug in the JobQueue (and added
      some kooky flags to make sure it stays dead)
    * Update the ministreaming lib to force mode=guaranteed if the default
      lib is used, and mode=best_effort for all other libs.

* Fixed up the configuration overrides for the streaming socket lib
      integration so that it properly honors env settings.

* Increase the tunnel test timeout rapidly if our tunnels are failing.
    * Honor message expirations for some tunnel jobs that were prematurely
      expired.
    * Streamline memory usage with temporary object caches and more efficient
      serialization for SHA256 calculation, logging, and both I2CP and I2NP
      message handling.
    * Fix some situations where we forward messages too eagerly.  For a
      request at the tunnel endpoint, if the tunnel is inbound and the target
      is remote, honor the message by tunnel routing the data rather than
      sending it directly to the requested location.

* Fix a strange race condition on i2cp client disconnect.
    * win98 startup fixes (thanks tester-1 and ardvark!)
    * include build scripts for the new streaming lib (which is NOT ready
      for use yet, but you can hack around with it)

48cdf17a4f * revamped locking to block on flush and close until all of the
packets through that point have been ACKed, throwing an
  InterruptedIOException if there was a writeTimeout or an IOException
  if the con failed
* revamped the ack/nack field settings to ack as much as possible
* handle some strange timeout/resend errors on connection
* pass 1/2rtt as the packet 'optional delay' field, and use that to
  schedule the ack time (the 'last' messages in a window set the
  optional delay to 0, asking for immediate ack of all received)
* increase the optional delay to 2 bytes (#ms to delay)
* inject random failures and delays if configured to do so in
  PacketHandler.choke
* fix up the window size adjustment (increment on ack, /= 2 on resend)
* use the highest RTT in the new RTT calculation so that we fit more
  in (via SACK)
* fix up the SACK handling (duh)
* revise the resend time calculation

15c227f568 * sliding windows w/ additive increase / multiplicitive decrease
* immediately send an ack on receiving a duplicate payload message

* only adjust the RTT when there have been no resends
* added some (disabled) throttles - randomly injecting delays on
  received packets, as well as randomly dropping them

8de41acfe1 * if we send a blank ACK message (that will not in turn be ACKed) and it
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
