    * Reduced some SimpleTimer churn
* add hooks for per-peer choking in the outbound message queue - if/when a
  peer reaches their cwin, no further messages will enter the 'active' pool
  until there are more bytes available.  other messages waiting (either later
  on in the same priority queue, or in the queues for other priorities) may
  take that slot.
* when we have a message acked, release the acked size to the congestion
  window (duh), rather than waiting for the second to expire and refill the
  capacity.
* send packets in a volley explicitly, waiting until we can allocate the full
  cwin size for that message

* more stats. including per-peer KBps (updated every second)
* improved blocking/timeout situations on the send queue
* added drop simulation hook
* provide logical RTO limits

jrandom authored 19 years ago and zzz committed 19 years ago

    * Reduce the peer profile stat coallesce overhead by inlining it with the
      reorganize.
    * Limit each transport to at most one address (any transport that requires
      multiple entry points can include those alternatives in the address).
udp stuff:
* change the UDP transport's style from "udp" to "SSUv1"
* keep track of each peer's skew
* properly handle session reestablishment over an existing session, rather
  than requiring both sides to expire first

jrandom authored 19 years ago and zzz committed 19 years ago

    * More fixes for the I2PTunnel "other" interface handling (thanks nelgin!)
    * Add back the code to handle bids from multiple transports (though there
      is still only one transport enabled by default)
    * Adjust the router's queueing of outbound client messages when under
      heavy load by running the preparatory job in the client's I2CP handler
      thread, thereby blocking additional outbound messages when the router is
      hosed.
    * No need to validate or persist a netDb entry if we already have it
And for some udp stuff:
* only bid on what we know (duh)
* reduceed the queue size in the UDPSender itself, so that ACKs go
  through more quickly, leaving the payload messages to queue up in
  the outbound fragment scheduler
* rather than /= 2 on congestion, /= 2/3 (still AIMD, but less drastic)
* adjust the fragment selector so a wsiz throttle won't force extra
  volleys
* mark congestion when it occurs, not after the message has been
  ACKed
* when doing a round robin over the active messages, move on to the
  next after a full volley, not after each packet (causing less "fair"
  performance but better latency)
* reduced the lock contention in the inboundMessageFragments by
  moving the ack and complete queues to the ACKSender and
  MessageReceiver respectively (each of which have their own
  threads)
* prefer new and existing UDP sessions to new TCP sessions, but
  prefer existing TCP sessions to new UDP sessions

    * Added button to router console for manual update checks.
    * Fixed bug in configupdate.jsp that caused the proxy port to be updated
      every time the form was submitted even if it hadn't changed.

* fail UDP sessions after two consecutive failed messages in different minutes
* honor UDP reconnections

jrandom authored 19 years ago and zzz committed 19 years ago

    * Added a pool of PRNGs using a different synchronization technique,
      hopefully sufficient to work around IBM's PRNG bugs until we get our
      own Fortuna.
    * In the streaming lib, don't jack up the RTT on NACK, and have the window
      size bound the not-yet-ready messages to the peer, not the unacked
      message count (not sure yet whether this is worthwile).
    * Many additions to the messageHistory log.
    * Handle out of order tunnel fragment delivery (not an issue on the live
      net with TCP, but critical with UDP).

and for udp stuff:
* implemented tcp-esque rto code in the udp transport
* make sure we don't ACK too many messages at once
* transmit fragments in a simple (nonrandom) order so that we can more easily
  adjust timeouts/etc.
* let the active outbound pool grow dynamically if there are outbound slots to
  spare
* use a simple decaying bloom filter at the UDP level to drop duplicate resent
  packets.

I removed those dumb platform specific makefiles.  They weren't doing what they ought anyway.  If there are platform specific issues, someone please tell me and I'll provide support for it here.  Or patch it yourself.
And this is the big "Fix the Parser" patch.  It turns the sam_parse function in src/parse.c into something that actually works.  Generating the argument list from an incoming SAM thingy is a bit memory churn-y; perhaps when I have time I'll replace all those strdups with structures that simply track the (start,end) indices.
Oh and also I moved i2p-ping to the new system.  Which required 0 change in code.  All I did was fix the Makefile, and add shared library libtool support.  Anyway, so enjoy folks.  It's rare I'm this productive

    * In the SDK, we don't actually need to block when we're sending a message
      as BestEffort (and these days, we're always sending BestEffort).
    * Pass out client messages in fewer (larger) steps.
    * Have the InNetMessagePool short circuit dispatch requests.
    * Have the message validator take into account expiration to cut down on
      false positives at high transfer rates.
    * Allow configuration of the probabalistic window size growth rate in the
      streaming lib's slow start and congestion avoidance phases, and default
      them to a more conservative value (2), rather than the previous value
      (1).
    * Reduce the ack delay in the streaming lib to 500ms
    * Honor choke requests in the streaming lib (only affects those getting
      insanely high transfer rates)
    * Let the user specify an interface besides 127.0.0.1 or 0.0.0.0 on the
      I2PTunnel client page (thanks maestro^!)
(plus minor udp tweaks)

* removed unnecessary references to i2ptunnel (though i2ptunnelxmlobject still references i2ptunnelxmlwrapper)

jrandom authored 19 years ago and zzz committed 19 years ago

    * Added the possibility for i2ptunnel client and httpclient instances to
      have their own i2p session (and hence, destination and tunnels).  By
      default, tunnels are shared, but that can be changed on the web
      interface or with the sharedClient config option in i2ptunnel.config.

    * Marked the net.i2p.i2ptunnel.TunnelManager as deprecated.  Anyone use
      this?  If not, I want to drop it (lots of tiny details with lots of
      duplicated semantics).

    * Added new user-editable eepproxy error page templates.
2005-04-17  jrandom
    * Revamp the tunnel building throttles, fixing a situation where the
      rebuild may not recover, and defaulting it to unthrottled (users with
      slow CPUs may want to set "router.tunnel.shouldThrottle=true" in their
      advanced router config)

    * Migrated to Bouncycastle's SHA256 and HMAC implementations for efficiency

    * Migrated to Bouncycastle's SHA256 and HMAC implementations for efficiency
(also lots of udp fixes)

jrandom authored 19 years ago and zzz committed 19 years ago

* use the new raw i2np message format (the previous corruptions were due to above)
* add a new test component (UDPFlooder) which floods all peers at the rate desired
* packet munging fix for highly fragmented messages
* include basic slow start code
* fixed the UDP peer rate refilling
* cleaned up some nextSend scheduling

jrandom authored 19 years ago and zzz committed 19 years ago

the basics (negotiate a session and send I2NP messages back and forth).  Lots,
lots more left.

jrandom authored 19 years ago and zzz committed 19 years ago

    * Make sure we don't get cached updates (thanks smeghead!)
    * Clear out the callback for the TestJob after it passes (only affects the
      job timing accounting)
