* 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!)

* New strict speed calculator that goes off the actual number of messages verifiably sent through the peer by way of tunnels. Initially, this only contains the successful message count on inbound tunnels, but may be augmented later to include verified outbound messages, peers queried in the netDb, etc. The speed calculation decays quickly, but should give a better differential than the previous stat (both values are shown on the /profiles.jsp page)

2005-03-11 jrandom * Rather than the fixed resend timeout floor (10s), use 10s+RTT as the minimum (increased on resends as before, of course). * Always prod the clock update listeners, even if just to tell them that the time hasn't changed much. * Added support for explicit peer selection for individual tunnel pools, which will be useful in debugging but not recommended for use by normal end users. * More aggressively search for the next hop's routerInfo on tunnel join. * Give messages received via inbound tunnels that are bound to remote locations sufficient time (taking into account clock skew). * Give alternate direct send messages sufficient time (10s min, not 5s) * Always give the end to end data message the explicit timeout (though the old default was sufficient before) * No need to give end to end messages an insane expiration (+2m), as we are already handling skew on the receiving side. * Don't complain too loudly about expired TunnelCreateMessages (at least, not until after all those 0.5 and 0.5.0.1 users upgrade ;) * Properly keep the sendBps stat * When running the router with router.keepHistory=true, log more data to messageHistory.txt * Logging updates * Minor formatting updates

2005-03-06 jrandom * Allow the I2PTunnel web interface to select streaming lib options for individual client tunnels, rather than sharing them across all of them, as we do with the session options. This way people can (and should) set the irc proxy to interactive and the eepproxy to bulk. * Added a startRouter.sh script to new installs which simply calls "sh i2prouter start". This should make it clear how people should start I2P.

* Filter HTTP response headers in the eepproxy, forcing Connection: close so that broken (/malicious) webservers can't allow persistent connections. All HTTP compliant browsers should now always close the socket. * Enabled the GZIPInputStream's cache (they were'nt cached before) * Make sure our first send is always a SYN (duh) * Workaround for some buggy compilers

* Loop while starting up the I2PTunnel instances, in case the I2CP listener isn't up yet (thanks detonate!) * Implement custom reusable GZIP streams to both reduce memory churn and prevent the exposure of data in the standard GZIP header (creation time, OS, etc). This is RFC1952 compliant, and backwards compatible, though has only been tested within the confines of I2P's compression use (DataHelper.[de]compress). * Preemptively support the next protocol version, so that after the 0.5.0.2 release, we'll be able to drop protocol=2 to get rid of 0.5 users.

* 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.

* Further streaming lib caching improvements * Reduce the minimum RTT (used to calculate retry timeouts), but also increase the RTT on resends. * Lower the default message size to 4KB from 16KB to further reduce the chance of failed fragmentation. * Extend tunnel rebuild throttling to include fallback rebuilds * If there are less than 20 routers known, don't drop the last 20 (to help avoid dropping all peers under catastrophic failures) * New stats for end to end messages - "client.leaseSetFoundLocally", "client.leaseSetFoundRemoteTime", and "client.leaseSetFailedRemoteTime"

* Reworked the tunnel (re)building process to remove the tokens and provide cleaner controls on the tunnels built. * Fixed situations where the timestamper wanted to test more servers than were provided (thanks Tracker!) * Get rid of the dead SAM sessions by using the streaming lib's callbacks (thanks Tracker!)

* Adjusted (and fixed...) the timestamper change detection * Deal with a rare reordering bug at the beginning of a stream (so we don't drop it unnecessarily) * Cleaned up some dropped message handling in the router * Reduced job queue churn when dealing with a large number of tunnels by sharing an expiration job * Keep a separate list of the most recent CRIT messages (shown on the logs.jsp). This way they don't get buried among any other messages. * For clarity, display the tunnel variance config as "Randomization" on the web console. * If lease republishing fails (boo! hiss!) try it again * Actually fix the negative jobLag in the right place (this time) * Allow reseeding when there are less than 10 known peer references * Lots of logging updates.

* Allow the streaming lib resend frequency to drop down to 20s as the minimum, so that up to 2 retries can get sent on an http request. * Add further limits to failsafe tunnels. * Keep exploratory and client tunnel testing and building stats separate. * Only use the 60s period for throttling tunnel requests due to transient network overload. * Rebuild tunnels earlier (1-3m before expiration, by default) * Cache the next hop's routerInfo for participating tunnels so that the tunnel participation doesn't depend on the netDb. * Fixed a long standing bug in the streaming lib where we wouldn't always unchoke messages when the window size grows. * Make sure the window size never reaches 0 (duh)

* Only build failsafe tunnels if we need them * Properly implement the selectNotFailingPeers so that we get a random selection of peers, rather than using the strictOrdering (thanks dm!) * Don't include too many "don't tell me about" peer references in the lookup message - only send the 10 peer references closest to the target.

* Only build new extra tunnels on failure if we don't have enough * Fix a fencepost in the tunnel building so that e.g. a variance of 2 means +/- 2, not +/- 1 (thanks dm!) * Avoid an NPE on client disconnect * Never select a shitlisted peer to participate in a tunnel * Have netDb store messages timeout after 10s, not the full 60s (duh) * Keep session tags around for a little longer, just in case (grr) * Cleaned up some closing event issues on the streaming lib * Stop bundling the jetty 5.1.2 and updated wrapper.config in the update so that 0.4.* users will need to do a clean install, but we don't need to shove an additional 2MB in each update to those already on 0.5. * Imported the susimail css (oops, thanks susi!)

* Fixed the braindead tunnel testing logic * If a large number of tunnels are failing (within the last 5-10 minutes) and the current tunnel pool's configuration allows it, randomly build a zero hop tunnel to replace failed tunnels. * Enable postman's POP3 and SMTP tunnels by default -
* Added some error handling when the number of session tags exceeds the realistic capacity, dropping a random chunk of received tag sets and conducting some minor analysis of the remaining ones. This is a part of a pretty serious error condition, and logs as CRIT (if/when people see "TOO MANY SESSION TAGS!", please let me know the full log line it puts in the wrapper.log or /logs.jsp) * Update the addressbook to only write to the published hosts location if the addressbook's config contains "should_publish=true" (by default, it contains "should_publish=false")

* (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++). -
