and fixed all the broken mainstream applications depending on it. Fixed a grave bug in SimpleTimer. Fixed Steraming Timer to be public. Fixed a pile of JavaDoc comments, and reformatted the files I touched.

* Reduced the growth factor on the slow start and congestion avoidance for the streaming lib. * Adjusted some of the I2PTunnelServer threading to use a small pool of handlers, rather than launching off new threads which then immediately launch off an I2PTunnelRunner instance (which launches 3 more threads..) * Don't persist session keys / session tags (not worth it, for now) * Added some detection and handling code for duplicate session tags being delivered (root cause still not addressed) * Make the PRNG's buffer size configurable (via the config property "i2p.prng.totalBufferSizeKB=4096") * Disable SSU flooding by default (duh) * Updates to the StreamSink apps for better throttling tests.

* Within the tunnel, use xor(IV, msg[0:16]) as the flag to detect dups, rather than the IV by itself, preventing an attack that would let colluding internal adversaries tag a message to determine that they are in the same tunnel. Thanks dvorak for the catch! * Drop long inactive profiles on startup and shutdown * /configstats.jsp: web interface to pick what stats to log * Deliver more session tags to account for wider window sizes * Cache some intermediate values in our HMACSHA256 and BC's HMAC * Track the client send rate (stream.sendBps and client.sendBpsRaw) * UrlLauncher: adjust the browser selection order * I2PAppContext: hooks for dummy HMACSHA256 and a weak PRNG * StreamSinkClient: add support for sending an unlimited amount of data * Migrate the tests out of the default build jars 2005-06-22 Comwiz * Migrate the core tests to junit

* 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)

* Update the old speed calculator and associated profile data points to use a non-tiered moving average of the tunnel test time, avoiding the freshness issues of the old tiered speed stats. * Explicitly synchronize all of the methods on the PRNG, rather than just the feeder methods (sun and kaffe only need the feeder, but it seems ibm needs all of them synchronized). * Properly use the tunnel tests as part of the profile stats. * Don't flood the jobqueue with sequential persist profile tasks, but instead, inject a brief scheduling delay between them. * Reduce the TCP connection establishment timeout to 20s (which is still absurdly excessive) * Reduced the max resend delay to 30s so we can get some resends in when dealing with client apps that hang up early (e.g. wget) * Added more alternative socketManager factories (good call aum!) -
* Adjust the old speed calculator to include end to end RTT data in its estimates, and use that as the primary speed calculator again. * Use the mean of the high capacity speeds to determine the fast threshold, rather than the median. Perhaps we should use the mean of all active non-failing peers? * Updated the profile page to sort by tier, then alphabetically. * Added some alternative socketManager factories (good call aum!)

* Really disable the streaming lib packet caching * Synchronized a message handling point in the SDK (even though its use is already essentially single threaded, its better to play it safe) * Don't add new RepublishLeaseSetJobs on failure, just requeue up the existing one (duh) * Throttle the number of concurrent pending tunnel builds across all pools, in addition to simply throttling the number of new requests per minute for each pool individually. This should avoid the cascading failure when tunnel builds take too long, as no new builds will be created until the previous ones are handled. * Factored out and extended the DataHelper's unit tests for dealing with long and date formatting. * Explicitly specify the HTTP auth realm as "i2prouter", though this alone doesn't address the bug where jetty asks for authentication too much. (thanks orion!) * Updated the StreamSinkServer to ignore all read bytes, rather than write them to the filesystem.

* (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!)

* 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.

* 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.

* 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

* Toss in a small pool of threads (3) to execute the events queued up with the SimpleTimer, as we do currently see the occational event notification spiking up to a second or so. * Implement a SAM client API in java, useful for event based streaming (or for testing the SAM bridge) * Added support to shut down the SAM bridge on OOM (useful if the SAM bridge is being run outside of the router). * Include the SAM test code in the sam.jar * Remove an irrelevent warning message from SAM, which was caused by perfectly normal operation due to a session being closed. * Removed some unnecessary synchronization in the streaming lib's PacketQueue * More quickly clean up the memory used by the streaming lib by immediately killing each packet's resend job as soon as it is ACKed (or cancelled), so that there are no longer any valid pointers to the (potentially 32KB) packet. * Fixed the timestamps dumped to stdout when debugging the PacketHandler. * Drop packets that would expand our inbound window beyond our maximum buffer size (default 32 messages) * Always read the ACK/NACK data from the verified packets received, even if we are going to drop them * Always adjust the window when there are messages ACKed, though do not change its size except as before. * Streamlined some synchronization in the router's I2CP handling * Streamlined some memory allocation in the SAM bridge * Default the streaming lib to disconnect on inactivity, rather than send an empty message. this still doesnt get the BT to where it needs to be, or fix the timeout problem, but i dont like having so many commits outstanding and these updates are sound

* Revised the installer to include start menu and desktop shortcuts for windows platforms, including pretty icons (thanks DrWoo!) * Allow clients specified in clients.config to have an explicit startup delay. * Update the default install to launch a browser pointing at the console whenever I2P starts up, rather than only the first time it starts up (configurable on /configservice.jsp, or in clients.config) * Bugfix to the clock skew checking code to monitor the delta between offsets, not the offset itself (duh) * Router console html update * New (and uuuuugly) code to verify that the wrapper.config contains the necessary classpath entries on update. If it has to update the wrapper.config, it will stop the JVM and service completely, since the java service wrapper doesn't reread the wrapper.config on JVM restart - requiring the user to manually restart the service after an update. * Increase the TCP connection timeout to 30s (which is obscenely long) ------------------------------------------------

* Remove spurious flush calls from I2PTunnel, and work with the I2PSocket's output stream directly (as the various implementations do their own buffering). * Another pass at a long standing JobQueue bug - dramatically simplify the job management synchronization since we dont need to deal with high contention (unlike last year when we had dozens of queue runners going at once). * Logging

2004-10-30 jrandom * Cache the temporary objects used in the AES encryption/decryption process so that AES doesn't require any memory allocation to process data. * Dramatically reduce memory usage within various crypto implementations by avoiding unnecessary (though simplifying) buffers. * If we specify some tags to be sent in an I2CP message explicitly, use only those, not those plus a new set (otherwise we aren't sure on ACK which set was delivered) * Allow configuration for the partial send timeout (how long before resending a message down a different tunnel in a lease). This can be updated with the "router.clientPartialSendTimeout" router config prop. * 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. -
