    * Short circuit a highly congested part of the stat logging unless its
      required (may or may not help with a synchronization issue reported by
      andreas)

complication authored 18 years ago and zzz committed 18 years ago

    * Allow a single build attempt to proceed despite 1-minute overload
      only if the 1-second rate shows enough spare bandwidth
      (e.g. overload has already eased)

complication authored 18 years ago and zzz committed 18 years ago

    * Correct a misnamed property in SummaryHelper.java
      to avoid confusion
    * Make the maximum allowance of our own concurrent
      tunnel builds slightly adaptive: one concurrent build per 6 KB/s
      within the fixed range 2..10
    * While overloaded, try to avoid completely choking our own build attempts,
      instead prefer limiting them to 1

    * Fixed URL in previous update, sorry

    * Weekly news.xml update

jrandom authored 18 years ago and zzz committed 18 years ago

    * Adjust the tunnel build timeouts to cut down on expirations, and
      increased the SSU connection establishment retransmission rate to
      something less glacial.
    * For the first 5 minutes of uptime, be less aggressive with tunnel
      exploration, opting for more reliable peers to start with.

    * Fix for a netDb lookup race (thanks cervantes!)

jrandom authored 18 years ago and zzz committed 18 years ago

    * Avoid a race in the message reply registry (thanks cervantes!)

jrandom authored 18 years ago and zzz committed 18 years ago

    * Fixed the tunnel expiration desync code (thanks Complication!)

    * weekly news.xml update

complication authored 18 years ago and zzz committed 18 years ago

    * Update news.xml to reflect 0.6.1.17

jrandom authored 18 years ago and zzz committed 18 years ago

    * Adjust how we pick high capacity peers to allow the inclusion of fast
      peers (the previous filter assumed an old usage pattern)
    * New set of stats to help track per-packet-type bandwidth usage better
    * Cut out the proactive tail drop from the SSU transport, for now
    * Reduce the frequency of tunnel build attempts while we're saturated
    * Don't drop tunnel requests as easily - prefer to explicitly reject them

complication authored 18 years ago and zzz committed 18 years ago

    * Update news.xml to reflect 0.6.1.16

jrandom authored 18 years ago and zzz committed 18 years ago

    * Adjust the proactive tunnel request dropping so we will reject what we
      can instead of dropping so much (but still dropping if we get too far
      overloaded)

jrandom authored 18 years ago and zzz committed 18 years ago

    * 0 isn't very random
    * Adjust the tunnel drop to be more reasonable

jrandom authored 18 years ago and zzz committed 18 years ago

    * -28.00230115311259 is not between 0 and 1 in any universe I know.
    * Made the bw-related tunnel join throttle much simpler

jrandom authored 18 years ago and zzz committed 18 years ago

    * Make some more stats graphable, and allow some internal tweaking on the
      tunnel pairing for creation and testing.

jrandom authored 18 years ago and zzz committed 18 years ago

    * Added a further failsafe against trying to queue up too many messages to
      a peer.

jrandom authored 18 years ago and zzz committed 18 years ago

    * Watch out for failed syndie index fetches (thanks bar!)

jrandom authored 18 years ago and zzz committed 18 years ago

    * Throttling improvements on SSU - throttle all transmissions to a peer
      when we are retransmitting, not just retransmissions.  Also, if
      we're already retransmitting to a peer, probabalistically tail drop new
      messages targetting that peer, based on the estimated wait time before
      transmission.
    * Fixed the rounding error in the inbound tunnel drop probability.

jrandom authored 18 years ago and zzz committed 18 years ago

    * Include a combined send/receive graph (good idea cervantes!)
    * Proactively drop inbound tunnel requests probabalistically as the
      estimated queue time approaches our limit, rather than letting them all
      through up to that limit.

jrandom authored 18 years ago and zzz committed 18 years ago

    * Stat summarization fix (removing the occational holes in the jrobin
      graphs)

jrandom authored 18 years ago and zzz committed 18 years ago

    * Process inbound tunnel requests more efficiently
    * Proactively drop inbound tunnel requests if the queue before we'd
      process it in is too long (dynamically adjusted by cpu load)
    * Adjust the tunnel rejection throttle to reject requeusts when we have to
      proactively drop too many requests.
    * Display the number of pending inbound tunnel join requests on the router
      console (as the "handle backlog")
    * Include a few more stats in the default set of graphs

    * Fix for a bug in the new irc ping/pong filter (thanks Complication!)

jrandom authored 18 years ago and zzz committed 18 years ago

    * Fixed a typo in the reply cleanup code

jrandom authored 18 years ago and zzz committed 18 years ago

    * Cut down on the time that we allow a tunnel creation request to sit by
      without response, and reject tunnel creation requests that are lagged
      locally.  Also switch to a bounded FIFO instead of a LIFO
    * Threading tweaks for the message handling (thanks bar!)
    * Don't add addresses to syndie with blank names (thanks Complication!)
    * Further ban clearance

    * weekly news.xml update

jrandom authored 18 years ago and zzz committed 18 years ago

    * Fix during the ssu handshake to avoid an unnecessary failure on
      packet retransmission (thanks ripple!)
    * Fix during the SSU handshake to use the negotiated session key asap,
      rather than using the intro key for more than we should (thanks ripple!)
    * Fixes to the message reply registry (thanks Complication!)
    * More comprehensive syndie banning (for repeated pushes)
    * Publish the router's ballpark bandwidth limit (w/in a power of 2), for
      testing purposes
    * Put a floor back on the capacity threshold, so too many failing peers
      won't cause us to pick very bad peers (unless we have very few good
      ones)
    * Bugfix to cut down on peers using introducers unneessarily (thanks
      Complication!)
    * Reduced the default streaming lib message size to fit into a single
      tunnel message, rather than require 5 tunnel messages to be transferred
      without loss before recomposition.  This reduces throughput, but should
      increase reliability, at least for the time being.
    * Misc small bugfixes in the router (thanks all!)
    * More tweaking for Syndie's CSS (thanks Doubtful Salmon!)

jrandom authored 18 years ago and zzz committed 18 years ago

    * Take out the router watchdog's teeth (don't restart on leaseset failure)
    * Filter the IRC ping/pong messages, as some clients send unsafe
      information in them (thanks aardvax and dust!)

jrandom authored 18 years ago and zzz committed 18 years ago

    * Substantially reduced the lock contention in the message registry (a
      major hotspot that can choke most threads).  Also reworked the locking
      so we don't need per-message timer events
    * No need to have additional per-peer message clearing, as they are
      either unregistered individually or expired.
    * Include some of the more transient tunnel throttling
