* (Merged the 0.5-pre branch back into CVS HEAD) * Replaced the old tunnel routing crypto with the one specified in router/doc/tunnel-alt.html, including updates to the web console to view and tweak it. * Provide the means for routers to reject tunnel requests with a wider range of responses: probabalistic rejection, due to approaching overload transient rejection, due to temporary overload bandwidth rejection, due to persistent bandwidth overload critical rejection, due to general router fault (or imminent shutdown) The different responses are factored into the profiles accordingly. * Replaced the old I2CP tunnel related options (tunnels.depthInbound, etc) with a series of new properties, relevent to the new tunnel routing code: inbound.nickname (used on the console) inbound.quantity (# of tunnels to use in any leaseSets) inbound.backupQuantity (# of tunnels to keep in the ready) inbound.length (# of remote peers in the tunnel) inbound.lengthVariance (if > 0, permute the length by adding a random # up to the variance. if < 0, permute the length by adding or subtracting a random # up to the variance) outbound.* (same as the inbound, except for the, uh, outbound tunnels in that client's pool) There are other options, and more will be added later, but the above are the most relevent ones. * Replaced Jetty 4.2.21 with Jetty 5.1.2 * Compress all profile data on disk. * Adjust the reseeding functionality to work even when the JVM's http proxy is set. * Enable a poor-man's interactive-flow in the streaming lib by choking the max window size. * Reduced the default streaming lib max message size to 16KB (though still configurable by the user), also doubling the default maximum window size. * Replaced the RouterIdentity in a Lease with its SHA256 hash. * Reduced the overall I2NP message checksum from a full 32 byte SHA256 to the first byte of the SHA256. * Added a new "netId" flag to let routers drop references to other routers who we won't be able to talk to. * Extended the timestamper to get a second (or third) opinion whenever it wants to actually adjust the clock offset. * Replaced that kludge of a timestamp I2NP message with a full blown DateMessage. * Substantial memory optimizations within the router and the SDK to reduce GC churn. Client apps and the streaming libs have not been tuned, however. * More bugfixes thank you can shake a stick at. 2005-02-13 jrandom * Updated jbigi source to handle 64bit CPUs. The bundled jbigi.jar still only contains 32bit versions, so build your own, placing libjbigi.so in your install dir if necessary. (thanks mule!) * Added support for libjbigi-$os-athlon64 to NativeBigInteger and CPUID (thanks spaetz!)

* Initial check-in of Pants, a new utility to help us manage our 3rd-party dependencies (Fortuna, Jetty, Java Service Wrapper, etc.). Some parts of Pants are still non-functional at this time so don't mess with it yet unless you want to potentially mangle your working copy of CVS.

* i2pProxy.pac, i2pbench.sh, and i2ptest.sh are now shipped with the dist packages and installed to $i2pinstalldir/scripts. * Added command line params to i2ptest.sh and i2pbench.sh: --gij to run them using gij + libgcj, and --sourcedir to run them from the source tree instead of the installation directory. * Fixed unreachable for() statement clause in the KBucketImpl class that was causing gcj to toss a compilation warning (jrandom++). -

* Added meaningful support for adjusting the preferred message size in the streaming lib by setting the i2p.streaming.maxMessageSize=32768 (or whatever). The other side will mimic a reduction (but never an increase). * Always make sure to use distinct ConnectionOption objects for each connection (duh) * Reduced the default ACK delay to 500ms on in the streaming lib * Only shrink the streaming window once per window * Don't bundle a new jetty.xml with updates * Catch another local routerInfo corruption issue on startup.

* Added support to the eepproxy for URLs such as http://localhost:4444/eepproxy/foo.i2p/bar/baz or even http://localhost:4444/eepproxy/foo.i2p/?i2paddresshelper=base64 -
* Caught a series of (previously unhandled) errors caused by requeueing messages that had timed out on the TCP transport (thanks mae^!) * Reduce the barrier to dropping session tags on streaming lib resends - every fourth send should drop the tags, forcing ElGamal encryption. This will help speed up the recovery after a disconnect, rather than the drop every fifth send.

2005-01-06 jrandom * Added a startup message to the addressbook, printing its version number to stdout (which is sent to wrapper.config) when it loads. * Updated the addressbook to reread the config file periodically * Added orion.i2p to the list of eepsites on the default homepage -
* Handle unexpected network read errors more carefully (thanks parg!) * Added more methods to partially compare (DataHelper) and display arrays (Base64.encode). * Exposed the AES encryptBlock/decryptBlock on the context.aes() * Be more generous on the throttle when just starting up the router * Fix a missing scheduled event in the streaming lib (caused after reset) * Add a new DisconnectListener on the I2PSocketManager to allow notification of session destruction. * Make sure our own router identity is valid, and if it isn't, build a new one and restart the router. Alternately, you can run the Router with the single command line argument "rebuild" and it will do the same.

* Revised the I2PTunnel client and httpclient connection establishment throttles. There is now a pool of threads that build the I2PSocket connections with a default size of 5, configurable via the I2PTunnel client option 'i2ptunnel.numConnectionBuilders' (if set to 0, it will not throttle the number of concurrent builders, but will launch a thread per socket during establishment). In addition, sockets accepted but not yet allocated to one of the connection builders will be destroyed after 30 seconds, configurable via 'i2ptunnel.maxWaitTime' (if set to 0, it will wait indefinitely).

* Add in a new keepalive event on each TCP connection, proactively sending a (tiny) time message every minute or two, as well as killing the connection if no message has been fully sent within 5 minutes or so. This should help deal with hung connections from IP address changes. -

* Cleaned up the postinstall/startup scripts a bit more to handle winME, and added windows info to the headless docs. (thanks ardvark!) * Fixed a harmless (yet NPE inspiring) race during the final shutdown of a stream (thanks frosk!) * Add a pair of new stats for monitoring tunnel participation - tunnel.participatingBytesProcessed (total # bytes transferred) and tunnel.participatingBytesProcessedActive (total # bytes transferred for tunnels whose byte count exceed the 10m average). This should help further monitor congestion issues. * Made the NamingService factory property public (thanks susi!)

* Added a new i2ptunnel type: 'httpserver', allowing you to specify what hostname should be sent to the webserver. By default, new installs will have an httpserver pointing at their jetty instance with the spoofed name 'mysite.i2p' (editable on the /i2ptunnel/edit.jsp page). -

* Catch another oddball case for a reset connection in the streaming lib. * Add a dumpprofile.jsp page, called with ?peer=base64OfPeerHash, which dumps the current state of that peer's profile. Instead of the full base64, you can pass in however many characters you have and it will return the first match found. -
* Remove the randomized factor in the tunnel rejection by bandwidth - we now accept the request if we've allocated less than our limit and reject it if we've allocated more. * Stick to the standard capacity scale on tunnel rejection, even for the 10m period. * Build the time message at the very last possible moment -
* Handle hard disconnects more gracefully within the streaming lib, and log unmonitored events more aggressively. * If we drop a peer after connection due to clock skew, log it to the /logs.jsp#connectionlogs with relevent info. In addition, toss it in the stat 'tcp.disconnectAfterSkew'. * Fixed the formatting in the skew display * Added an ERROR message that is fired once after we run out of routerInfo files (thanks susi!) * Set the connect timeout equal to the streaming lib's disconnect timeout if not already specified (the I2PTunnel httpclient already enforces a 60s connect timeout) * Fix for another connection startup problem in the streaming lib. * Fix for a stupid error in the probabalistic drop (rand <= P, not > P) * Adjust the capacity calculations so that tunnel failures alone in the last 10m will not trigger a 0 capacity rank.

* Periodically send a message along all I2NP connections with the router's current time, allowing the receiving peer to determine that the clock has skewed too much, and hence, disconnect. For backwards compatability reasons, this is being kludged into a DeliveryStatusMessage (ewww). The next time we have a backwards compatability break, we can put in a proper message setup for it. -
* Reenable the probabalistic drop on the TCP queues to deal with good old fashioned bandwidth limiting. However, by default the probability is rigged to reserve 0% of the queue free - meaning we just aggressively fail messages in the queue if we're transferring too slowly. That reservation factor can be increased with 'tcp.queueFreeFactor=0.25' (or whatever) and the drop code can be disabled with the parameter 'tcp.dropProbabalistically=false'. * Still penalize a peer on tunnel failure, but don't immediately drop their capacity to 0. * More aggressively ACK duplicates * Randomize the timestamper period * Display the clock skew on the connection logs when a peer sends it. * Allow the timestamper to fix skews of up to 10 minutes * Logging

* Added some error checking on the new client send job (thanks duck!) * Implemented tunnel rejection based on bandwidth usage (rejecting tunnels proportional to the bytes allocated in existing tunnels vs the bytes allowed through the bandwidth limiter). * Enable a new configuration parameter for triggering a tunnel rebuild (tunnel.maxTunnelFailures), where that is the max allowed test failures before killing the tunnel (default 0). * Gather more data that we rank capacity by (now we monitor and balance the data from 10m/30m/60m/1d instead of just 10m/60m/1d). * Fix a truncation/type conversion problem on the long term capacity values (we were ignoring the daily stats outright)

* Fix the missing HTTP timeout, which was caused by the deferred syn used by default. This, in turn, meant the I2PSocket creation doesn't fail on .connect, but is unable to transfer any data in any direction. We now detect that condition for the I2PTunnelHTTPClient and throw up the right error page. * Logging -
* Use a simpler and less memory intensive job for processing outbound client messages when the session is in mode=bestEffort. We can immediately discard the data as soon as its sent the first time, rather than wait for an ack, since we will never internally resend. * Reduce some synchronization to avoid a rare deadlock * Replaced 'localhost' with 127.0.0.1 in the i2ptunnel config, and special case it within the tunnel controller. * Script cleanup for building jbigi/jcpuid * Logging
