* Handle a rare race under high bandwidth situations in the SSU transport
* Minor refactoring so we don't confuse sun's 1.6.0-b2 validator
2006-02-21 Complication
* Reactivate TCP tranport by default, in addition to re-allowing
* 2006-02-21 0.6.1.11 released
2006-02-21 jrandom
* Throttle the outbound SSU establishment queue, so it doesn't fill up the
heap when backlogged (and so that the messages queued up on it don't sit
there forever)
* Further SSU memory cleanup
* Clean up the address regeneration code so it knows when to rebuild the
local info more precisely.
2006-02-20 jrandom
* Properly enable TCP this time (oops)
* Deal with multiple form handlers on the same page in the console without
being too annoying (thanks blubb and bd_!)
2006-02-20 jrandom
* Reenable the TCP transport as a fallback (we'll continue to muck with
debugging SSU-only elsewhere)
2006-02-20 jrandom
* Major SSU and router tuning to reduce contention, memory usage, and GC
churn. There are still issues to be worked out, but this should be a
substantial improvement.
* Modified the optional netDb harvester task to support choosing whether
to use (non-anonymous) direct connections or (anonymous) exploratory
tunnels to do the harvesting. Harvesting itself is enabled via the
advanced config "netDb.shouldHarvest=true" (default is false) and the
connection type can be chosen via "netDb.harvestDirectly=false" (default
is false).
2006-02-19 dust
* Added pruning of suckers history (it used to grow indefinitely).
2006-02-19 jrandom
* Moved the current net's reseed URL to a different location than where
the old net looks (dev.i2p.net/i2pdb2/ vs .../i2pdb/)
* More aggressively expire inbound messages (on receive, not just on send)
* Add in a hook for breaking backwards compatibility in the SSU wire
protocol directly by including a version as part of the handshake. The
version is currently set to 0, however, so the wire protocol from this
build is compatible with all earlier SSU implementations.
* Increased the number of complete message readers, cutting down
substantially on the delay processing inbound messages.
* Delete the message history file on startup
* Reworked the restart/shutdown display on the console (thanks bd_!)
2006-02-18 jrandom
* Migrate the outbound packets from a central component to the individual
per-peer components, substantially cutting down on lock contention when
dealing with higher degrees.
* Load balance the outbound SSU transfers evenly across peers, rather than
across messages (so peers with few messages won't be starved by peers
with many).
* Reduce the frequency of router info rebuilds (thanks bar!)
2006-02-18 jrandom
* Add a new AIMD throttle in SSU to control the number of concurrent
messages being sent to a given peer, in addition to the throttle on the
number of concurrent bytes to that peer.
* Adjust the existing SSU outbound queue to throttle based on the queue's
lag, not an arbitrary number of packets.
2006-02-17 jrandom
* Properly fix the build request queue throttling, using queue age to
detect congestion, rather than queue size.
2006-02-17 jrandom
* Disable the message history log file by default (duh - feel free to
delete messageHistory.txt after upgrading. thanks deathfatty!)
* Limit the size of the inbound tunnel build request queue so we don't
get an insane backlog of requests that we're bound to reject, and adjust
the queue processing so we keep on churning through them when we've got
a backlog.
* Small fixes for the multiuser syndie operation (thanks Complication!)
* Renamed modified PRNG classes that were imported from gnu-crypto so we
don't conflict with JVMs using that as a JCE provider (thanks blx!)
* 2006-02-16 0.6.1.10 released
2006-02-16 jrandom
* Add a new toggle to the web config to enable/disable the load testing
2006-02-16 jrandom
* Dropped much of the abandonware from the apps/ directory
2006-02-16 jrandom
* Bugfix to the I2PTunnel web config to properly accept i2cp port settings
* Initial sucker refactoring to simplify reuse of the html parsing
* Beginnings of hooks to push imported rss/atom out to remote syndie
archives automatically (though not enabled currently)
* Further SSU peer test cleanup
2006-02-15 jrandom
* Add in per-blog RSS feeds to Syndie
* Upgraded sucker's ROME dependency to 0.8, bundling sucked enclosures
with the posts, marking additional attachments as Media RSS enclosures
(http://search.yahoo.com/mrss/), since RSS only supports one enclosure
per item.
* Don't allow the default syndie user to be set to something invalid if
its in single user mode.
2006-02-15 jrandom
* Merged in the i2p_0_6_1_10_PRE branch to the trunk, so CVS HEAD is no
longer backwards compatible (and should not be used until 0.6.1.1 is
out)
2006-02-14 jrandom
* Syndie ui bugfixes (thanks all!)
2006-02-13 jrandom
* Use the current directory for some temporary I2PSnark files, rather than
the OS default temp dir (thanks anon!)
* Increase the base streaming lib window size (still shrinks to 1 on
retransmission though, of course)
* Fixed the I2PTunnel newlines to work with lighthttpd (thanks all!)
* Implement fast retransmit in the streaming lib (fires at most once per
packet), and increased the default ack delay to 2 seconds (from .5s)
* Don't ask for garlic level message acks for end to end messages unless
they're useful (e.g. to ack session tags)
2006-02-12 cervantes
* Use a different santisation method for some SML attributes
* Make router console update config save button actually save.
* Fix console bandwidth limiter burst rate dropdowns, so the display
relates to what is saved in the config.
2006-02-12 cervantes
* SML is now stricter in it's formatting (attributes should only use
double quotes instead of being allowed to mix with singles).
* Using apostrophes in SML attributes will no longer invalidate the tag.
* Some instances of [blog] tag description were not being displayed
correctly.
2006-02-12 jrandom
* Further SSU peer test throttling
* Put the most common router console features on the main index page too
2006-02-11 jrandom
* Be more careful about SSU peer test floods
2006-02-09 jrandom
* Adjusted one of the SSU timeouts so we don't drop peers as easily (duh)
2006-02-08 jrandom
* Added transparent support for VIA C3 CPUs to jbigi (thanks Nekow42), and
bundled a precompiled libjbigi.so in the jbigi.jar
* Cleaned up the synchronization for some SSU packet handling code
* Allow explicit rejection of more lagged tunnel build requests, rather
than dropping them outright
* Use lighter load testing
2006-02-07 jrandom
* Handle HTTP headers without any values (thanks Sugadude!)
* Don't show the option to make Syndie multiuser, since very few people
need it, and multiuser mode is a lot more complex to use. Geeks can
enable it by adding "syndie.singleUser=false" to syndie/syndie.config
(or in the router's advanced config, for the embedded Syndie)
* When a peer rejects participation in a tunnel, they mean it (duh)
* Decrease tunnel test timeout period to 20s (a 40s lag is insane)
* Remove a throttle on the size of the SSU active outbound pool, since
it was essentially arbitrary
* Use a more appropriate SSU bloom filter size
* Don't "proactively" drop SSU connections if we have partially received
inbound messages (duh)
* Migrate most of the message state across SSU connection reestablishment
2006-02-06 jrandom
* Reduce the SSU retransmit timeout range, and increase the number of ACKs
piggybacked
2006-02-05 jrandom
* Experiment with short exponents for DH/ElGamal, using a 226bit x instead
of a 2048bit x, as reports suggest that size is sufficient for 2048bit
DH/ElGamal when using safe primes (see KeyGenerator.java for references)
* Enable the messageHistory.txt by default, for debugging
2006-02-05 jrandom
* Substantial bugfix for the duplicate message detection in the transport
layer
* Handle tunnel build responses ASAP, rather than queueing them up to wait
in line (processing them is really fast - just a few AES loops)
* Don't bother handling build requests that we have queued up for a while
locally, as the requestor will have timed it out anyway (perhaps we
should reply regardless, but with a backoff instead?)
2006-02-04 jrandom
* Further tunnel test cleanup and disabling of the old tunnel creation
code
2006-02-04 jrandom
* Clean up and reenable the tunnel testing for the new tunnel system.
2006-02-04 jrandom
* Don't cache the archive.txt in syndie when fetching it through the web
interface.
* Logging updates
2006-02-03 jrandom
* Added further replay prevention on the tunnel build requests
* More aggressive streaming lib closing on reset
2006-02-03 jrandom
* More aggressive refusal of peers from the wrong network (oops)
2006-02-01 jrandom
* Instruct the router to reseed against a new URL, for migration purposes:
http://dev.i2p.net/i2pdb2/
* Aggressive error handling during UDP packet creation (thanks cervantes)
2006-02-01 jrandom
* Fix the new tunnel creation crypto, including the addition of a 4 byte
"next message ID" to the encrypted request structure in the spec.
* Backwards incompatible change, using the new tunnel creation crypto, the
fixed MD5 HMAC size, and a new network ID (to prevent cross pollination
with the old incompatible network).
* Reworked the leaseSet request process to handle a race condition
* Disable the TCP transport
* Run four separate threads on the job queue to cut down on job lag
2006-01-28 jrandom
* Removed a race that could show up in leaseSet requesting with the new
tunnel building process
2006-01-25 jrandom
* Run the peer profile coalescing/reorganization outside the job queue
(on one of the timers), to cut down on some job queue congestion. Also,
trim old profiles while running, not just when starting up.
* Slightly more sane intra-floodfill-node netDb activity (only flood new
entries)
* Workaround in the I2PTunnelHTTPServer for some bad requests (though the
source of the bug is not yet addressed)
* Better I2PSnark reconnection handling
* Further cleanup in the new tunnel build process
* Make sure we expire old participants properly
* Remove much of the transient overload throttling (it wasn't using a good
metric)
2006-01-25 dust
* Fix IRC client proxy to use ISO-8859-1.
2006-01-22 jrandom
* New tunnel build process - does not use the new crypto or new peer
selection strategies. However, it does drop the fallback tunnel
procedure, except for tunnels who are configured to allow them, or for
the exploratory pool during bootstrapping or after a catastrophic
failure. This new process prefers to fail rather than use too-short
tunnels, so while it can do some pretty aggressive tunnel rebuilding,
it may expose more tunnel failures to the user.
* Always prefer normal tunnels to fallback tunnels.
* Potential fix for a bug while changing i2cp settings on I2PSnark (thanks
bar!)
* Do all of the netDb entry writing in a separate thread, avoiding
duplicates and batching them up.
2006-01-19 Complication
* Explain better where eepsite's destkey can be found
2006-01-18 cervantes
* Add title attributes to all external links in Syndie, so we can rollover
and quickly see if it's worth clicking on.
* Fixed a minor compiler warning.
2006-01-17 jrandom
* First pass of the new tunnel creation crypto, specified in the new
router/doc/tunnel-alt-creation.html (referenced in the current
router/doc/tunnel-alt.html). It isn't actually used anywhere yet, other
than in the test code, but the code verifies the technical viability, so
further scrutiny would be warranted.
2006-01-16 cervantes
* Dragged I2P kicking and screaming into 2006 (Oops)
2006-01-14 cervantes
* Removed entirely misleading memory status from the console summary.
2006-01-13 cervantes
* Further Syndie layout hardening and typeface balancing.
* 2006-01-12 0.6.1.9 released
2006-01-12 jrandom
* Only create the loadtest.log if requested to do so (thanks zzz!)
* Make sure we cleanly take into consideration the appropriate data
points when filtering out duplicate messages in the message validator,
and report the right bloom filter false positives rate (not used for
anything except debugging)
2006-01-12 cervantes
* Syndie CSS tweaks to removed some redundant declarations, improve font
scaling and layout robustness. Improved cross browser compatibility
(in other words "kicked IE"). Tightened the look of the blog template
a little.
2006-01-11 Complication
* CSS comment fixes
2006-01-11 jrandom
* Include the attachments/blogs/etc for comments on the blog view
* Syndie HTML fixes (thanks cervantes!)
* Make sure we fully reset the objects going into our cache before we
reuse them (thanks zzz!)
2006-01-10 jrandom
* Added the per-post list of attachments/blogs/etc to the blog view in
Syndie (though this does not yet include comments or some further
refinements)
* Have the I2P shortcut launch i2p.exe instead of i2psvc.exe on windows,
removing the dox box (though also removes the restart functionality...)
* Give the i2p.exe the correct java.library.path to support the systray
dll (thanks Bobcat, Sugadude, anon!)
2006-01-09 jrandom
* Removed a longstanding bug that had caused unnecessary router identity
churn due to clock skew
* Temporarily sanity check within the streaming lib for long pending
writes
* Added support for a blog-wide logo to Syndie, and automated the pushing
of updated extended blog info data along side the metadata.
2006-01-09 jrandom
* Bugfix for a rare SSU error (thanks cervantes!)
* More progress on the blog interface, allowing customizable blog-wide
links.
2006-01-08 jrandom
* First pass of the new blog interface, though without much of the useful
customization features (coming soon)
2006-01-04 jrandom
* Rather than profile individual tunnels for throughput over their
lifetime, do so at 1 minute intervals (allowing less frequently active
tunnels to be more fairly measured).
* Run the live tunnel load test across two tunnels at a time, by default.
The load test runs for a random period from 90s to the tunnel lifetime,
self paced. This should help gathering data for profiling peers that
are in exploratory tunnels.
2006-01-03 jrandom
* Calculate the overall peer throughput across the 3 fastest one minute
tunnel throughput values, rather than the single fastest throughput.
* Degrade the profiled throughput data over time (cutting the profiled
peaks in half once a day, on average)
* Enable yet another new speed calculation for profiling peers, using the
peak throughput from individual tunnels that a peer is participating in,
rather than across all tunnels they are participating in. This helps
gather a fairer peer throughput measurement, since it won't allow a slow
high capacity peer seem to have a higher throughput (pushing a little
data across many tunnels at once, as opposed to lots of data across a
single tunnel). This degrades over time like the other.
* Add basic OS/2 support to the jbigi code (though we do not bundle a
precompiled OS/2 library)
2006-01-01 jrandom
* Disable multifile torrent creation in I2PSnark's web UI for the moment
(though it can still seed and participate in multifile swarms)
* Enable a new speed calculation for profiling peers, using their peak
1 minute average tunnel throughput as their speed.
2005-12-31 jrandom
* Include a simple torrent creator in the I2PSnark web UI
* Further streaming lib closing improvements
* Refactored the load test components to run off live tunnels (though,
still not safe for normal/anonymous load testing)
2005-12-30 jrandom
* Close streams more gracefully
2005-12-30 jrandom
* Small streaming lib bugfixes for the modified timeouts
* Minor Syndie/Sucker RSS html fix
* Small synchronization fix in I2PSnark (thanks fsm!)
2005-12-30 jrandom
* Replaced the bundled linux jcpuid (written in C++) with scintilla's
jcpuid (written in C), removing the libg++.so.5 dependency that has bit
some distros (e.g. mandriva)
2005-12-29 jrandom
* Minor fix to the new ERR-ClockSkew to deal with people whose clocks are
actually correct
2005-12-27 jrandom
* Add a new Status: line on the router console - "ERR-ClockSkew", in case
the clock is too skewed to do anything useful (check the year and month,
not just the hour and minute).
* Fixed the read/write timeouts in the streaming lib (so that it actually
honors them now)
* Minor I2PSnark cleanups (no read timeout, more careful shutdown and
torrent closing)
* Handle an oddball tunnel creation failure (thanks Xunk)
2005-12-26 Complication
* Fix some integer typecasting in I2PSnark (caused >2GB torrents to fail)
* HTML readability cosmetics on "Peers" page
* 2005-12-22 0.6.1.8 released
2005-12-22 jrandom
* Bundle the standalone I2PSnark launcher in the installer and update
process (launch as "java -jar launch-i2psnark.jar", viewing the
interface on http://localhost:8002/)
* Don't autostart swarming torrents by default so that you can run a
standalone I2PSnark from the I2P install dir and not have the embedded
I2PSnark autolaunch the torrents that the standalone instance is running
* Fixed a rare streaming lib bug that could let a blocking call wait
forever.
2005-12-22 jrandom
* Cleaned up some buffer synchronization issues in I2PSnark that could
cause blockage.
2005-12-21 jrandom
* Adjusted I2PSnark's usage of the streaming lib (tweaking it for BT's
behavior)
* Fixed the I2PSnark bug that would lose track of live peers
2005-12-20 jrandom
* Enabled the control in I2PSnark to toggle whether torrents should be
started automatically or not
* Hopefully finished the last hook to close down torrents completely when
they're stopped.
2005-12-19 jrandom
* Fix for old Syndie blog bookmarks (thanks Complication!)
* Fix for I2PSnark to accept incoming connections again (oops)
* Randomize the order that peers from the tracker are contacted
2005-12-19 jrandom
* I2PSnark logging, disconnect old inactive peers rather than new ones,
memory usage reduction, better OOM handling, and a shared connection
acceptor.
* Cleaned up the Syndie blog page and the resulting filters (viewing a
blog from the blog page shows threads started by the selected author,
not those that they merely participate in)
2005-12-18 jrandom
* Added a standalone runner for the I2PSnark web ui (build with the
command "ant i2psnark", unzip i2psnark-standalone.zip somewhere, run
with "java -jar launch-i2psnark.jar", and go to http://localhost:8002/).
* Further I2PSnark error handling
2005-12-17 jrandom
* Let multiuser accounts authorize themselves to access the remote
functionality again (thanks Ch0Hag!)
* Adjust the JVM heap size to 128MB for new installs (existing users can
accomplish this by editing wrapper.config, adding the line
"wrapper.java.maxmemory=128", and then doing a full shutdown and startup
of the router). This is relevent for heavy usage of I2PSnark in the
router console.
2005-12-17 jrandom
* Use our faster SHA1, rather than the JVM's within I2PSnark, and let
'piece' sizes grow larger than before.
2005-12-16 jrandom
* Added some I2PSnark sanity checks, an OOMListener when running
standalone, and a guard against keeping memory tied up indefinitely.
* Sanity check on the watchdog (thanks zzz!)
* Handle invalid HTTP requests in I2PTunnel a little better
2005-12-16 jrandom
* Moved I2PSnark from using Threads to I2PThreads, so we handle OOMs
properly (thanks Complication!)
* More guards in I2PSnark for zany behavior (I2PSession recon w/ skew,
b0rking in the DirMonitor, etc)
2005-12-16 jrandom
* Try to run a torrent in readonly mode if we can't write to the file, and
handle failures a little more gracefully (thanks polecat!)
2005-12-16 jrandom
* Refuse torrents with too many files (128), avoiding ulimit errors.
* Remove an fd leak in I2PSnark
* Further I2PSnark web UI cleanup
2005-12-15 jrandom
* Added a first pass to the I2PSnark web UI (see /i2psnark/)
2005-12-15 jrandom
* Added multitorrent support to I2PSnark, accessible currently by running
"i2psnark.jar --config i2psnark.config" (which may or may not exist).
It then joins the swarm for any torrents in ./i2psnark/*.torrent, saving
their data in that directory as well. Removing the .torrent file stops
participation, and it is currently set to seed indefinitely. Completion
is logged to the logger and standard output, with further UI interaction
left to the (work in progress) web UI.
2005-12-14 jrandom
* Fix to drop peer references when we shitlist people again (thanks zzz!)
* Further I2PSnark fixes to deal with arbitrary torrent info attributes
(thanks Complication!)
2005-12-13 zzz
* Don't test tunnels expiring within 90 seconds
* Defer Test Tunnel jobs if job lag too large
* Use JobQueue.getMaxLag() rather than the jobQueue.jobLag stat to measure
job lag for tunnel build backoff, allowing for more agile handling
(since the stat is only updated once a minute)
* Use tunnel length override if all tunnels are expiring within one
minute.
2005-12-13 jrandom
* Fixed I2PSnark's handling of some torrent files to deal with those
created by Azureus and I2PRufus (it didn't know how to deal with
additional meta info, such as path.utf-8 or name.utf-8).
2005-12-09 zzz
* Create different strategies for exploratory tunnels (which are difficult
to create) and client tunnels (which are much easier)
* Gradually increase number of parallel build attempts as tunnel expiry
nears.
* Temporarily shorten attempted build tunnel length if builds using
configured tunnel length are unsuccessful
* React more aggressively to tunnel failure than routine tunnel
replacement
* Make tunnel creation times randomized - there is existing code to
randomize the tunnels but it isn't effective due to the tunnel creation
strategy. Currently, most tunnels get built all at once, at about 2 1/2
to 3 minutes before expiration. The patch fixes this by fixing the
randomization, and by changing the overlap time (with old tunnels) to a
range of 2 to 4 minutes.
* Reduce number of excess tunnels. Lots of excess tunnels get created due
to overlapping calls. Just about anything generated a call which could
build many tunnels all at once, even if tunnel building was already in
process.
* Miscellaneous router console enhancements
2005-12-08 jrandom
* Minor bugfix in SSU for dealing with corrupt packets
* Added some hooks for load testing
2005-12-07 jrandom
* Added a first pass at a blog view in Syndie
2005-12-07 jrandom
* Expand the thread we're viewing to its leaf
* Bugfix on intraday ordering (children are always newer than parents)
2005-12-05 jrandom
* Added an RDF and XML thread export to Syndie, reachable at
.../threadnav/rdf or .../threadnav/xml, accepting the parameters
count=$numThreads and offset=$threadIndex. If the $numThreads is -1, it
displays all threads.
2005-12-04 TLorD
* Patch for the C SAM library to null terminate strings on copy (thanks!)
2005-12-04 jrandom
* Bugfix in Syndie for a problem in the threaded indexer (thanks CofE!)
* Always include ourselves in the favorite authors (since we don't
bookmark ourselves)
2005-12-03 jrandom
* Use newgroup-like tags by default in Syndie's interface
2005-12-03 jrandom
* Added support for a 'most recent posts' view that CofE requested, which
includes the ability to filter by age (e.g. posts by your favorite
authors in the last 5 days).
2005-12-03 jrandom
* Adjusted Syndie to use the threaded view that cervantes suggested, which
displays a a single thread path at a time - from root to leaf - rather
than a depth first traversal.
2005-12-03 jrandom
* Package up a standalone Syndie install into a "syndie-standalone.zip",
buildable with "ant syndie". It extracts into ./syndie/, launches with
"java -jar launchsyndie.jar" (or javaw, on windows, to avoid a dos box),
running a single user Syndie instance (by default). It also creates a
default subscription to syndiemedia without any anonymity (using no
proxy). Upgrades can be done by just replacing the syndie.war with the
one from I2P.
* 2005-12-01 0.6.1.7 released
2005-12-01 jrandom
* Add a new criteria to the tunnel join throttle, backing off people if we
are failing to talk to our peers more than usual.
2005-11-30 jrandom
* Cleaned up the build process to deal with Jetty 5.1.6 and rename the
new commons-logging-api.jar to commons-logging.jar, which it replaces.
Jetty 5.1.6 is pushed with all updates. Also, no need to push a
separate jdom or rome, as they're inside syndie.war.
2005-11-30 jrandom
* Don't let the TCP transport alone shitlist a peer, since other
transports may be working. Also display whether TCP connections are
inbound or outbound on the peers page.
* Fixed some substantial bugs in the SSU introducers where we wouldn't
talk to anyone who didn't expose an IP (even if they had introducers),
among other goofy things.
* When dealing with SSU introducers, send them all a packet at 3s/6s/9s,
rather than sending one a packet at 3s, then another a packet at 6s,
and a third a packet at 9s.
* Fixed Syndie attachments (oops)
2005-11-29 zzz
* Added a link to orion's jump page on the 'key not found' error page.
2005-11-29 jrandom
* Further Syndie UI cleanup
* Bundled our patched MultiPartRequest code from jetty (APL2 licensed),
since it hasn't been applied to the jetty CVS yet [1]. Its packaged
into syndie.jar and renamed to net.i2p.syndie.web.MultiPartRequest, but
will be removed as soon as its integrated into Jetty. This patch allows
posting content in various character sets.
[1] http://article.gmane.org/gmane.comp.java.jetty.general/6031
* Upgraded new installs to the latest stable jetty (5.1.6), though this
isn't pushed as part of the update yet, as there aren't any critical
bugs.
2005-11-29 jrandom
* Added back in the OSX jbigi, which was accidentally removed a few revs
back (thanks for the bug report stoerte!) New installs will get the
full jbigi, or you can pull the jbigi.jar from CVS by going to
http://dev.i2p.net/cgi-bin/cvsweb.cgi/i2p/installer/lib/jbigi/jbigi.jar
and clicking on the first "download" link, saving that jbigi.jar to
lib/jbigi.jar in your I2P installation directory. After restarting your
router, it should load up fine.
2005-11-27 jrandom
* Inlined the Syndie CSS to reduce the number of HTTP requests (and
because firefox [and others?] delay rendering until they fetch the css).
* Make sure we fire the shutdown tasks when regenerating a new identity
(thanks picsou!)
* Cleaned up some of the things I b0rked in the 'dynamic keys' mode
* Don't drop SSU sessions if they're still transmitting data successfully,
even if there are transmission failures
* Adjusted the time summarization to display hours after 119m, not 90m
* Further EepGet cleanup (grr)
* 2005-11-26 0.6.1.6 released
2005-11-26 jrandom
* Update the sorting in Syndie to consider children 'newer' than parents,
even if they have the same message ID (duh)
* Cleaned up some nav links in Syndie (good idea gloin, spaetz!)
* Added a bunch of tooltips to Syndie's fields (thanks polecat!)
* Force support for nonvalidating XML in Jetty (so we can handle GCJ/etc
better)
2005-11-26 jrandom
* Be more explicit about what messages we will handle through a client
tunnel, and how we will handle them. This cuts off a set of attacks
that an active adversary could mount, though they're probably nonobvious
and would require at least some sophistication.
2005-11-26 Raccoon23
* Added support for 'dynamic keys' mode, where the router creates a new
router identity whenever it detects a substantial change in its public
address (read: SSU IP or port). This only offers minimal additional
protection against trivial attackers, but should provide functional
improvement for people who have periodic IP changes, since their new
router address would not be shitlisted while their old one would be.
* Added further infrastructure for restricted route operation, but its use
is not recommended.
2005-11-25 jrandom
* Further Syndie UI cleanups
* Logging cleanup
* Fixed link to fproxy.tino.i2p (thanks zzz!)
2005-11-25 jrandom
* Don't publish stats for periods we haven't reached yet (thanks zzz!)
* Cleaned up the syndie threaded display to show the last updated date for
a subthread, and to highlight threads updated in the last two days.
2005-11-24 jrandom
* Fix to save syndication settings in Syndie (thanks spaetz!)
2005-11-23 jrandom
* Removed spurious streaming lib RTO increase (it wasn't helpful)
* Streamlined the tunnel batching to schedule batch transmissions more
appropriately.
* Default tunnel pool variance to 2 +0-1 hops
2005-11-21 jrandom
* IE doesn't strip SPAN from <button> form fields, so add in a workaround
within I2PTunnel.
* Increase the maximum SSU retransmission timeout to accomodate slower or
more congested links (though SSU's RTO calculation will usually use a
much lower timeout)
* Moved the streaming lib timed events off the main timer queues and onto
a streaming lib specific set of timer queues. Streaming lib timed
events are more likely to have lock contention on the I2CP socket while
other timed events in the router are (largely) independent.
* Fixed a case sensitive lookup bug (thanks tino!)
* Syndie cleanup - new edit form on the preview page, and fixed some blog
links (thanks tino!)
2005-11-19 jrandom
* Implemented a trivial pure java PMTU backoff strategy, switching between
a 608 byte MTU and a 1350 byte MTU, depending upon retransmission rates.
* Fixed new user registration in Syndie (thanks Complication!)
2005-11-17 jrandom
* More cautious file handling in Syndie
2005-11-16 jrandom
* More aggressive I2PTunnel content encoding munging to work around some
rare HTTP behavior (ignoring q values on Accept-encoding, using gzip
even when only identity is specified, etc). I2PTunnelHTTPServer now
sends "Accept-encoding: \r\n" plus "X-Accept-encoding: x-i2p-gzip\r\n",
and I2PTunnelHTTPServer handles x-i2p-gzip in either the Accept-encoding
or X-Accept-encoding headers. Eepsite operators who do not know to
check for X-Accept-encoding will simply use the identity encoding.
* 2005-11-15 0.6.1.5 released
2005-11-14 jrandom
* Migrate to the new Syndie interface
2005-11-11 jrandom
* Add filtering threads by author to Syndie, populated with authors in the
user's addressbook
* When creating the default user, add
"http://syndiemedia.i2p/archive/archive.txt" to their addressbook,
configured to automatically pull updates. (what other archives should
be included?)
* Tiny servlet to help dole out the new routerconsole themes, and bundle
the installer/resources/themes/** into ./docs/themes/** on both install
and update.
2005-11-11 cervantes
* Initial pass of the routerconsole revamp, starting with I2PTunnel and
being progressively rolled out to other sections at later dates.
Featuring abstracted W3C strict XHTML1.0 markup, with CSS providing
layout and styling.
* Implemented console themes. Users can create their own themes by
creating css files in: {i2pdir}/docs/themes/console/{themename}/
and activating it using the routerconsole.theme={themename} advanced
config property. Look at the example incomplete "defCon1" theme.
Note: This is very much a work in progress. Folks might want to hold-off
creating their own skins until the markup has solidified.
* Added "routerconsole.javascript.disabled=true" to disable console
client-side scripting and "routerconsole.css.disabled=true" to remove
css styling (only rolled out in the i2ptunnel interface currently)
* Fixed long standing bug with i2ptunnel client and server edit screens
where tunnel count and depth properties would fail to save. Added
backup quantity and variance configuration options.
* Added basic accessibility support (key shortcuts, linear markup, alt and
title information and form labels).
* So far only tested on IE6, Firefox 1.0.6, Opera 8 and lynx.
2005-11-11 jrandom
* Default Syndie to single user mode, and automatically log into a default
user account (additional accounts can be logged into with the 'switch'
or login pages, and new accounts can be created with the register page).
* Disable the 'automated' column on the Syndie addressbook unless the user
is appropriately authorized (good idea Polecat!)
2005-11-10 jrandom
* First pass to a new threaded Syndie interface, which isn't enabled by
default, as its not done yet.
2005-11-06 jrandom
* Include SSU establishment failure in the peer profile as a commError,
as we do for TCP establishment failures.
* Don't throttle the initial transmission of a message because of ongoing
retransmissions to a peer, since the initial transmission of a message
is more valuable than a retransmission (since it has less latency).
* Cleaned up links to SusiDNS and I2PTunnel (thanks zzz!)
2005-11-05 jrandom
* Include the most recent ACKs with packets, rather than only sending an
ack exactly once. SSU differs from TCP in this regard, as TCP has ever
increasing sequence numbers, while each message ID in SSU is random, so
we don't get the benefit of later ACKs implicitly ACKing earlier
messages.
* Reduced the max retransmission timeout for SSU
* Don't try to send messages queued up for a long time waiting for
establishment.
2005-11-05 dust
* Fix sucker to delete its temporary files.
* Improve sucker's sml output some.
* Fix Exception in SMLParser for weird sml.
2005-11-03 zzz
* Added a new error page to the eepproxy to differentiate the full 60
second timeout from the immediate "I don't know this base64" failure.
2005-11-01 jrandom
* Added a few more css elements (thanks identiguy!)
2005-10-31 jrandom
* Fix for some syndie reply scenarios (thanks identiguy and CofE!)
* Removed a potentially infinitely recursive call (oops)
2005-10-30 dust
* Merge sucker into syndie with a rssimport.jsp page.
* Add getContentType() to EepGet.
* Make chunked transfer work (better) with EepGet.
* Do replaceAll("<","<") for logs.
* 2005-10-29 0.6.1.4 released
2005-10-29 jrandom
* Improved the bandwidth throtting on tunnel participation, especially for
low bandwidth peers.
* Improved failure handling in SSU with proactive reestablishment of
failing idle peers, and rather than shitlisting a peer who failed too
much, drop the SSU session and allow a new attempt (which, if it fails,
will cause a shitlisting)
* Clarify the cause of the shitlist on the profiles page, and include
bandwidth limiter info at the bottom of the peers page.
2005-10-26 jrandom
* In Syndie, propogate the subject and tags in a reply, and show the parent
post on the edit page for easy quoting. (thanks identiguy and CofE!)
* Streamline some netDb query handling to run outside the jobqueue -
which means they'll run on the particular SSU thread that handles the
message. This should help out heavily loaded netDb peers.
2005-10-25 jrandom
* Defer netDb searches for newly referenced peers until we actually want
them
* Ignore netDb references to peers on our shitlist
* Set the timeout for end to end client messages to the max delay after
finding the leaseSet, so we don't have as many expired messages floating
around.
* Add a floor to the streaming lib window size
* When we need to send a streaming lib ACK, try to retransmit one of the
unacked packets instead (with updated ACK/NACK fields, of course). The
bandwidth cost of an unnecessary retransmission should be minor as
compared to both an ACK packet (rounded up to 1KB in the tunnels) and
the probability of a necessary retransmission.
* Adjust the streaming lib cwin algorithm to allow growth after a full
cwin messages if the rtt is trending downwards. If it is not, use the
existing algorithm.
* Increased the maximum rto size in the streaming lib.
* Load balancing bugfix on end to end messages to distribute across
tunnels more evenly.
2005-10-22 jrandom
* Integrated GNU-Crypto's Fortuna PRNG, seeding it off /dev/urandom and
./prngseed.rnd (if they exist), and reseeding it with data out of
various crypto operations (unused bits in a DH exchange, intermediary
bits in a DSA signature generation, extra bits in an ElGamal decrypt).
The Fortuna implementation under gnu.crypto.prng has been modified to
use BouncyCastle's SHA256 and Cryptix's AES (since those are the ones
I2P uses), and the resulting gnu.crypto.prng.* are therefor available
under GPL+Classpath's linking exception (~= LGPL). I2P's SecureRandom
wrapper around it is, of course, public domain.
2005-10-20 dust
* Fix bug in ircclient that prevented it to use its own dest (i.e. was
always shared. (thx for info Ragnarok)
* Fix crash in Sucker with some bad html.
2005-10-20 jrandom
* Workaround a bug in GCJ's Calendar implementation
* Propery throw an exception in the streaming lib if we try to write to a
closed stream. This will hopefully help clear some I2Phex bugs (thanks
GregorK!)
2005-10-19 jrandom
* Ported the snark bittorrent client to I2P such that it is compatible
with i2p-bt and azneti2p. For usage information, grab an update and run
"java -jar lib/i2psnark.jar". It isn't currently multitorrent capable,
but adding in support would be fairly easy (see PeerAcceptor.java:49)
* Don't allow leaseSets expiring too far in the future (thanks postman)
2005-10-19 jrandom
* Bugfix for the auto-update code to handle different usage patterns
* Decreased the addressbook recheck frequency to once every 12 hours
instead of hourly.
* Handle dynamically changing the HMAC size (again, unless your nym is
toad or jrandom, ignore this ;)
* Cleaned up some synchronization/locking code
2005-10-17 dust
* Exchange the remaining URL with EepGet in Sucker.
* Allow /TOPIC irc command.
2005-10-17 jrandom
* Allow an env prop to configure whether we want to use the backwards
compatible (but not standards compliant) HMAC-MD5, or whether we want
to use the not-backwards compatible (but standards compliant) one. No
one should touch this setting, unless your name is toad or jrandom ;)
* Added some new dummy facades
* Be more aggressive on loading up the router.config before building the
router context
* Added new hooks for apps to deal with previously undefined I2NP message
types without having to modify any code.
* Demo code for using a castrated router for SSU comm (SSUDemo.java)
2005-10-14 jrandom
* More explicit filter for linux/PPC building (thanks anon!)
* Fixed Syndie's Sucker to not explicitly reference something only found
in sun's JVM (thanks cervantes!)
* Don't filter IRC "MAP" messages (not critical, but it doesn't hurt)
* 2005-10-14 0.6.1.3 released
2005-10-14 jrandom
* Added a key explaining peers.jsp a bit (thanks tethra!)
2005-10-13 dust
* Bundled dust's Sucker for pulling RSS/Atom content into SML, which can
then be injected into Syndie with the Syndie CLI.
* Bundled ROME and JDOM (BSD and Apache licensed, respectively) for
RSS/Atom parsing.
2005-10-13 jrandom
* SSU retransmission choke bugfix (== != !=)
* Include initial transmissions in the retransmission choke, so that
if we are already retransmitting a message, we won't send anything
to that peer other than that message (or ACKs, if necessary)
2005-10-12 jrandom
* Choke SSU retransmissions to a peer while there is already a
retransmission in flight to them. This currently lets other initial
transmissions through, since packet loss is often sporadic, but maybe
this should block initial transmissions as well?
* Display the retransmission bytes stat on peers.jsp (thanks bar!)
* Filter QUIT messages in the I2PTunnelIRCClient proxy
2005-10-11 jrandom
* Piggyback the SSU partial ACKs with data packets. This is backwards
compatible.
* Syndie RSS renderer bugfix, plus now include the full entry instead of
just the blurb before the cut.
2005-10-11 jrandom
* Piggyback the SSU explicit ACKs with data packets (partial ACKs aren't
yet piggybacked). This is backwards compatible.
* SML parser cleanup in Syndie
2005-10-10 dust
* Implemented a new I2PTunnelIRCClient which locally filters inbound and
outbound IRC commands for anonymity and security purposes, removing all
CTCP messages except ACTION, as well as stripping the hostname from the
USER message (while leaving the nick and 'full name'). The IRC proxy
doesn't use this by default, but you can enable it by creating a new
"IRC proxy" tunnel on the web interface, or by changing the tunnel type
to "ircclient" in i2ptunnel.config.
2005-10-10 jrandom
* I2PTunnel http client config cleanup and stats
* Minor SSU congestion tweaks and stats
* Reduced netDb exploration period
2005-10-09 jrandom
* Syndie CLI cleanup for simpler CLI posting. Usage shown with
java -jar lib/syndie.jar
* Beginnings of the Syndie logging cleanup
* Delete corrupt Syndie posts
2005-10-09 jrandom
* Now that the streaming lib works reasonably, set the default inactivity
event to send a 0 byte keepalive payload, rather than disconnecting the
stream. This should cut the irc netsplits and help out with other long
lived streams. The default timeout is now less than the old timeout as
well, so the keepalive will be sent before earlier builds fire their
fatal timeouts.
2005-10-08 jrandom
* Use the OS clock for stat timing, since it doesn't jump around (though
still use the NTP'ed clock for display)
* Added new DH stats
* 2005-10-07 0.6.1.2 released
2005-10-07 jrandom
* Include the 1 second bandwidth usage on the console rather than the
1 minute rate, as the 1 second value doesn't have the 1m/5m quantization
issues.
2005-10-07 jrandom
* Allow the I2PTunnelHTTPServer to send back the first few packets of an
HTTP response quicker, and initialize the streaming lib's cwin more
carefully.
* Added a small web UI to the new Syndie scheduled updater. If you log in
as a user authorized to use the remote archive funtionality, you can
request remote archives in your address book to be automatically pulled
down by checking the "scheduled?" checkbox.
2005-10-05 jrandom
* Allow the first few packets in the stream to fill in their IDs during
handshake (thanks cervantes, Complication, et al!) This should fix at
least some of the intermittent HTTP POST issues.
2005-10-04 jrandom
* Syndie patch for single user remote archives (thanks nickless_head!)
* Handle an invalid netDb store (thanks Complication!)
2005-10-04 jrandom
* Further reduction in unnecessary streaming packets.
2005-10-03 jrandom
* Properly reject unroutable IP addresses *cough*
2005-10-03 rangarok
* Changed default update delay to twelve hours, and enforced a minimum
delay of one hour.
2005-10-03 ragnarok
* Implemented a Syndie auto-updater. It will automatically pull new posts
from selected syndie archives. To try it out, add
syndie.updateArchives=<comma seperated list of syndie archives> to your
syndie.config. Archives must be specified as the full url to archive.txt
(e.g. http://syndiemedia.i2p/archive/archive.txt). By default, it checks
for new posts every hour. This can be modified by setting
syndie.updateDelay=<delay in hours> also in syndie.config.
* 2005-10-01 0.6.1.1 released
2005-09-30 ragnarok
* Implemented conditional get for syndie remote archive imports.
2005-09-30 jrandom
* Killed three more streaming lib bugs, one of which caused excess packets
to be transmitted (dupacking dupacks), one that was the root of many of
the old hung streams (shrinking highest received), and another that was
releasing data too soon.
2005-09-30 jrandom
* Only allow autodetection of our IP address if we haven't received an
inbound connection in the last two minutes.
* Increase the default max streaming resends to 8 from 5 (and down from
the earlier 10)
2005-09-29 ragnarok
* Export petnames from syndie to the router's petname db instead of
userhosts.txt.
2005-09-29 jrandom
* Support noreseed.i2p in addition to .i2pnoreseed for disabling automatic
reseeding - useful on OSes that make it hard to create dot files.
Thanks Complication (and anon)!
* Fixed the installer version string (thanks Frontier!)
* Added cleaner rejection of invalid IP addresses, shitlist those who send
us invalid IP addresses, verify again that we are not sending invalid IP
addresses, and log an error if it happens. (Thanks Complication, ptm,
and adab!)
* 2005-09-29 0.6.1 released
2005-09-29 jrandom
* Let syndie users modify their metadata.
* Reseed the router on startup if there aren't enough peer references
known locally. This can be disabled by creating the file .i2pnoreseed
in your home directory, and the existing detection and reseed handling
on the web interface is unchanged.
2005-09-28 jrandom
* Fix for at least some (all?) of the wrong stream errors in the streaming
lib
2005-09-27 jrandom
* Properly suggest filenames for attachments in Syndie (thanks all!)
* Fixed the Syndie authorization scheme for single user vs. multiuser
2005-09-27 jrandom
* I2PTunnel bugfix (thanks Complication!)
* Increase the SSU cwin slower during congestion avoidance (at k/cwin^2
instead of k/cwin)
* Limit the number of inbound SSU sessions being built at once (using
half of the i2np.udp.maxConcurrentEstablish config prop)
* Don't shitlist on a message send failure alone (unless there aren't any
common transports).
* More careful bandwidth bursting
2005-09-26 jrandom
* Reworded the SSU introductions config section (thanks duck!)
* Force identity content encoding for I2PTunnel httpserver requests
(thanks redzara!)
* Further x-i2p-gzip bugfixes for the end of streams
* Reduce the minimum bandwidth limits to 3KBps steady and burst (though
I2P's performance at 3KBps is another issue)
* Cleaned up some streaming lib structures
2005-09-25 jrandom
* Allow reseeding on the console if the netDb knows less than 30 peers,
rather than less than 10 (without internet connectivity, we keep the
last 15 router references)
* Reenable the x-i2p-gzip HTTP processing by default, flushing the stream
more aggressively.
* Show the status that used to be called "ERR-Reject" as "OK (NAT)"
* Reduced the default maximum number of streaming lib resends of a packet
(10 retransmits is a bit much with a reasonable RTO)
2005-09-25 Complication
* Better i2paddresshelper handling in the I2PTunnel httpclient, plus a new
conflict resolution page if the i2paddresshelper parameter differs from
an existing name to destination mapping.
2005-09-25 jrandom
* Fix a long standing streaming lib bug (in the inactivity detection code)
* Improved handling of initial streaming lib packet retransmissions to
kill the "lost first packet" bug (where a page shows up with the first
few KB missing)
* Add support for initial window sizes greater than 1 - useful for
eepsites to transmit e.g. 4 packets full of data along with the initial
ACK, thereby cutting down on the rtt latency. The congestion window
size can and does still shrink down to 1 packet though.
* Adjusted the streaming lib retransmission calculation algorithm to be
more TCP-like.
2005-09-21 redzara
* Use ISO-8859-1 for the susidns xml
2005-09-21 susi

2005-09-21 jrandom
* Add support for HTTP POST to EepGet
* Use HTTP POST for syndie bulk fetches, since there's a lot of data to
put in that URL.
2005-09-18 jrandom
* Added support for pure 64bit linux with jbigi and the java service
wrapper (no need for jcpuid if we're on os.arch=amd64). Thanks mule

* UI cleanup in Syndie (thanks gloin and bar!)
2005-09-18 Ragnarok
* Made MetaNamingService the default naming service.
2005-09-17 Ragnarok
* Implemented a naming service using Syndie's petname db. It's not enabled
by default, but you can try it out by setting
i2p.naming.impl=net.i2p.client.naming.PetNameNamingService in
router.config.
* Implemented a meta naming service that will first lookup names in the
PetNameNamingService then fallback on the HostTxtNamingService. Which
naming services are checked and in which order is specified by
i2p.nameservicelist. This will probably become the default naming service
so please help test it out by setting
i2p.naming.impl=net.i2p.client.naming.MetaNamingService in router.config.

2005-09-17 jrandom
* Clean up syndie a bit more and bundle a default introductory post with
both new installs and updates.
* Typo fixes on the console (thanks bar!)
2005-09-17 jrandom
* Updated the bandwidth limiter to use two tiers of bandwidth - our normal
steady state rate, plus a new limit on how fast we transfer when
bursting. This is different from the old "burst as fast as possible
until we're out of tokens" policy, and should help those with congested
networks. See /config.jsp to manage this rate.
* Bugfixes in Syndie to handle missing cache files (no data was lost, the
old posts just didn't show up).
* Log properly in EepPost
2005-09-17 jrandom
* Added the natively compiled jbigi and patched java service wrapper for
OS X. Thanks Bill Dorsey for letting me use your machine!
* Don't build i2p.exe or i2pinstall.exe when run on OS X machines, as we
don't bundle the binutils necessary (and there'd be a naming conflict
if we did).
* Added 'single user' functionality to syndie - if the single user
checkbox on the admin page is checked, all users are allowed to control
the instance and sync up with remote syndie nodes.
* Temporarily disable the x-i2p-gzip in i2ptunnel until it is more closely
debugged.
2005-09-16 jrandom
* Reject unroutable IPs in SSU like we do for the TCP transport (unless
you have i2np.udp.allowLocal=true defined - useful for private nets)
2005-09-16 jrandom
* Adjust I2PTunnelHTTPServer so it can be used for outproxy operators
(just specify the spoofed host as an empty string), allowing them to
honor x-i2p-gzip encoding.
* Let windows users build the exes too (thanks bar and redzara!)
* Allow I2PTunnel httpserver operators to disable gzip compression on
individual tunnels with the i2ptunnel.gzip=false client option
(good idea susi!)
2005-09-16 jrandom
* Added the i2p.exe and i2pinstall.exe for windows users, using launch4j.
* Added runplain.sh for *nix/osx users having problems using the java
service wrapper (called from the install dir as: sh runplain.sh)
* Bundle susidns and syndie, with links on the top nav
* Have I2PTunnelHTTPClient and I2PTunnelHTTPServer use the x-i2p-gzip
content-encoding (if offered), reducing the payload size before it
reaches the streaming lib. The existing compression is at the i2cp
level, so we've been packetizing 4KB of uncompressed data and then
compressing those messages, rather than compressing and then packetizing
4KB of compressed data. This should reduce the number of round trips
to fetch web pages substantially.
* Adjust the startup and timing of the addressbook so that susidns always
has config to work off, and expose a method for susidns to tell it to
reload its config and rerun.
2005-09-15 jrandom
* Error handling for failed intro packets (thanks red.hand!)
* More carefully verify intro addresses
2005-09-13 jrandom
* More careful error handling with introductions (thanks dust!)
* Fix the forceIntroducers checkbox on config.jsp (thanks Complication!)
* Hide the shitlist on the summary so it doesn't confuse new users.
2005-09-12 comwiz
* Migrated the router tests to junit
2005-09-12 jrandom
* Removed guaranteed delivery mode entirely (so existing i2phex clients
using it can get the benefits of mode=best_effort). Guaranteed delivery
is offered at the streaming lib level.
* Improve the peer selection code for peer testing, as everyone now
supports tests.
* Give the watchdog its fangs - if it detects obscene job lag or if
clients have been unable to get a leaseSet for more than 5 minutes,
restart the router. This was disabled a year ago due to spurious
restarts, and can be disabled by "watchdog.haltOnHang=false", but the
cause of the spurious restarts should be gone.
2005-09-12 jrandom
* Bugfix for skewed store which could kill a UDP thread (causing complete
comm failure and eventual OOM)
2005-09-12 jrandom
* More aggressively publish updated routerInfo.
* Expose the flag to force SSU introductions on the router console
* Don't give people the option to disable SNTP time sync, at least not
through the router console, because there is no reason to disable it.
No, not even if your OS is "ntp synced", because chances are, its not.
2005-09-10 jrandom
* Test the router's reachability earlier and more aggressively
* Use the low level bandwidth limiter's rates for the router console, and
if the router has net.i2p.router.transport.FIFOBandwidthLimiter=INFO in
the logger config, keep track of the 1 second transfer rates as the stat
'bw.sendBps1s' and 'bw.recvBps1s', allowing closer monitoring of burst
behavior.
2005-09-09 jrandom
* Added preliminary support for NAT hole punching through SSU introducers
* Honor peer test results from peers that we have an SSU session with if
those sessions are idle for 3 minutes or more.

* New build due to change in build number :P (thanks ugha!)
2005-09-07 BarkerJr
* HTML cleanup for the router console (thanks!)
2005-09-07 jrandom
* Lay the foundation for 'client routers' - the ability for peers to opt
out of participating in tunnels entirely due to firewall/NAT issues.
Individual routers have control over where those peers are used in
tunnels - in outbound or inbound, exploratory or client tunnels, or
none at all. The defaults with this build are to simply act as before -
placing everyone as potential participants in any tunnel.
* Another part of the foundation includes the option for netDb
participants to refuse to answer queries regarding peers who are marked
as unreachable, though this too is disabled by default (meaning the
routerInfo is retrievable from the netDb).
2005-09-05 jrandom
* Expose the HTTP headers to EepGet status listeners
* Handle DSA key failures properly (if the signature is not invertable, it
is obviously invalid)
2005-09-04 jrandom
* Don't persist peer profiles until we are shutting down, as the
persistence process gobbles RAM and wall time.
* Bugfix to allow you to check/uncheck the sharedClient setting on the
I2PTunnel web interface (thanks BarkerJr!)
* Be more careful when expiring a failed tunnel message fragment so we
don't drop the data while attempting to read it.
* 2005-09-02 0.6.0.5 released

* Don't refuse to send a netDb store if the targetted peer has failed a
bit (the value was an arbitrary amount).
* Logging changes
* 2005-09-01 0.6.0.4 released
2005-09-01 jrandom
* Don't send out a netDb store of a router if it is more than a few hours
old, even if someone asked us for it.
2005-08-31 jrandom
* Don't publish leaseSets to the netDb if they will never be looked for -
namely, if they are for destinations that only establish outbound
streams. I2PTunnel's 'client' and 'httpclient' proxies have been
modified to tell the router that it doesn't need to publish their
leaseSet (by setting the I2CP config option 'i2cp.dontPublishLeaseSet'
to 'true').
* Don't publish the top 10 peer rankings of each router in the netdb, as
it isn't being watched right now.
2005-08-29 jrandom
* Added the new test Floodfill netDb
2005-08-27 jrandom
* Minor logging and optimization tweaks in the router and SDK
* Use ISO-8859-1 in the XML files (thanks redzara!)
* The consolePassword config property can now be used to bypass the router
console's nonce checking, allowing CLI restarts
2005-08-24 jrandom
* Catch errors with corrupt tunnel messages more gracefully (no need to
kill the thread and cause an OOM...)
* Don't skip shitlisted peers for netDb store messages, as they aren't
necessarily shitlisted by other people (though they probably are).
* Adjust the netDb store per-peer timeout based on each particular peer's
profile (timeout = 4x their average netDb store response time)
* Don't republish leaseSets to *failed* peers - send them to peers who
replied but just didn't know the value.
* Set a 5 second timeout on the I2PTunnelHTTPServer reading the client's
HTTP headers, rather than blocking indefinitely. HTTP headers should be
sent entirely within the first streaming packet anyway, so this won't be
a problem.
* Don't use the I2PTunnel*Server handler thread pool by default, as it may
prevent any clients from accessing the server if the handlers get
blocked by the streaming lib or other issues.
* Don't overwrite a known status (OK/ERR-Reject/ERR-SymmetricNAT) with
Unknown.
2005-08-23 jrandom
* Removed the concept of "no bandwidth limit" - if none is specified, its
16KBps in/out.
* Include ack packets in the per-peer cwin throttle (they were part of the
bandwidth limit though).
* Tweak the SSU cwin operation to get more accurrate estimates under
congestions.
* SSU improvements to resend more efficiently.
* Added a basic scheduler to eepget to fetch multiple files sequentially.
* 2005-08-21 0.6.0.3 released
2005-08-21 jrandom
* If we already have an established SSU session with the Charlie helping
test us, cancel the test with the status of "unknown".
2005-08-17 jrandom
* Revise the SSU peer testing protocol so that Bob verifies Charlie's
viability before agreeing to Alice's request. This doesn't work with
older SSU peer test builds, but is backwards compatible (older nodes
won't ask newer nodes to participate in tests, and newer nodes won't
ask older nodes to either).
2005-08-12 jrandom
* Keep detailed stats on the peer testing, publishing the results in the
netDb.
* Don't overwrite the status with 'unknown' unless we haven't had a valid
status in a while.
* Make sure to avoid shitlisted peers for peer testing.
* When we get an unknown result to a peer test, try again soon afterwards.
* When a peer tells us that our address is different from what we expect,
if we've done a recent peer test with a result of OK, fire off a peer
test to make sure our IP/port is still valid. If our test is old or the
result was not OK, accept their suggestion, but queue up a peer test for
later.
* Don't try to do a netDb store to a shitlisted peer, and adjust the way
we monitor netDb store progress (to clear up the high netDb.storePeers
stat)
2005-08-10 jrandom
* Deployed the peer testing implementation to be run every few minutes on
each router, as well as any time the user requests a test manually. The
tests do not reconfigure the ports at the moment, merely determine under
what conditions the local router is reachable. The status shown in the
top left will be "ERR-SymmetricNAT" if the user's IP and port show up
differently for different peers, "ERR-Reject" if the router cannot
receive unsolicited packets or the peer helping test could not find a
collaborator, "Unknown" if the test has not been run or the test
participants were unreachable, or "OK" if the router can receive
unsolicited connections and those connections use the same IP and port.
* 2005-08-08 0.6.0.2 released
2005-08-08 jrandom
* Add a configurable throttle to the number of concurrent outbound SSU
connection negotiations (via i2np.udp.maxConcurrentEstablish=4). This
may help those with slow connections to get integrated at the start.
* Further fixlets to the streaming lib
2005-08-07 Complication
* Display the average clock skew for both SSU and TCP connections
2005-08-07 jrandom
* Fixed the long standing streaming lib bug where we could lose the first
packet on retransmission.
* Avoid an NPE when a message expires on the SSU queue.
* Adjust the streaming lib's window growth factor with an additional
Vegas-esque congestion detection algorithm.
* Removed an unnecessary SSU session drop
* Reduced the MTU (until we get a working PMTU lib)
* Deferr tunnel acceptance until we know how to reach the next hop,
rejecting it if we can't find them in time.
* If our netDb store of our leaseSet fails, give it a few seconds before
republishing.
* 2005-08-03 0.6.0.1 released
2005-08-03 jrandom
* Backed out an inadvertant change to the netDb store redundancy factor.
* Verify tunnel participant caching.
* Logging cleanup
2005-08-01 duck
* Update IzPack to 3.7.2 (build 2005.04.22). This fixes bug #82.
2005-08-01 duck
* Fix an addressbook NPE when a new hostname from the master addressbook
didn't exist in the router addressbook.
* Fix an addressbook bug which caused subscriptions not to be parsed at
all. (Oops!)
2005-07-31 jrandom
* Adjust the netDb search and store per peer timeouts to match the average
measured per peer success times, rather than huge fixed values.
* Optimized and reverified the netDb peer selection / retrieval process
within the kbuckets.
* Drop TCP connections that don't have any useful activity in 10 minutes.
* If i2np.udp.fixedPort=true, never change the externally published port,
even if we are autodetecting the IP address.
* 2005-07-27 0.6 released
2005-07-27 jrandom
* Enabled SSU as the default top priority transport, adjusting the
config.jsp page accordingly.
* Add verification fields to the SSU and TCP connection negotiation (not
compatible with previous builds)
* Enable the backwards incompatible tunnel crypto change as documented in
tunnel-alt.html (have each hop encrypt the received IV before using it,
then encrypt it again before sending it on)
* Disable the I2CP encryption, leaving in place the end to end garlic
encryption (another backwards incompatible change)
* Adjust the protocol versions on the TCP and SSU transports so that they
won't talk to older routers.
* Fix up the config stats handling again
* Fix a rare off-by-one in the SSU fragmentation
* Reduce some unnecessary netDb resending by inluding the peers queried
successfully in the store redundancy count.
2005-07-22 jrandom
* Use the small thread pool for I2PTunnelHTTPServer (already used for
I2PTunnelServer)
* Minor memory churn reduction in I2CP
* Small stats update
2005-07-21 jrandom
* Fix in the SDK for a bug which would manifest itself as misrouted
streaming packets when a destination has many concurrent streaming
connections (thanks duck!)
* No more "Graceful shutdown in -18140121441141s"
2005-07-20 jrandom
* Allow the user to specify an external port # for SSU even if the external
host isn't specified (thanks duck!)
2005-07-19 jrandom
* Further preparation for removing I2CP crypto
* Added some validation to the DH key agreement (thanks $anon)
* Validate tunnel data message expirations (though not really a problem,
since tunnels expire)
* Minor PRNG threading cleanup
2005-07-15 cervantes
* Added workaround for an odd win32 bug in the stats configuration console
page which meant only the first checkbox selection was saved.
2005-07-15 Romster
* Added per group selection toggles in the stats configuration console
page.
2005-07-13 jrandom
* Fixed a recently injected bug in the multitransport bidding which had
allowed an essentially arbitrary choice of transports, rather than the
properly ordered choice.
2005-07-13 jrandom
* Fixed a long standing bug where we weren't properly comparing session
tags but instead largely depending upon comparing their hashCode,
causing intermittent decryption errors.
2005-07-12 jrandom
* Add some data duplication to avoid a recently injected concurrency
problem in the session tag manager (thanks redzara and romster).
2005-07-11 jrandom
* 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.
2005-07-05 jrandom
* Use a buffered PRNG, pulling the PRNG data off a larger precalculated
buffer, rather than the underlying PRNG's (likely small) one, which in
turn reduces the frequency of recalcing.
* More tuning to reduce temporary allocation churn
2005-07-04 jrandom
* 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
2005-05-25 duck
* Fixed PRNG bug (bugzilla #107)
2005-05-01 jrandom
* Added a substantial optimization to the AES engine by caching the
prepared session keys (duh).
2005-05-01 jrandom
* Cleaned up the peers page a bit more.
2005-04-30 jrandom
* Added a small new page to the web console (/peers.jsp) which contains
the peer connection information. This will be cleaned up a lot more
before 0.6 is out, but its a start.
2005-04-30 jrandom
* Reduced some SimpleTimer churn
2005-04-29 jrandom
* 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).
2005-04-28 jrandom
* 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
2005-04-25 smeghead
* 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.
2005-04-24 jrandom
* 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).
* 2005-04-20 0.5.0.7 released
2005-04-20 jrandom
* 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^!)
2005-04-17 sirup
* 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.
2005-04-17 jrandom
* 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).
2005-04-17 zzz
* 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)
2005-04-16 jrandom
* Migrated to Bouncycastle's SHA256 and HMAC implementations for efficiency
2005-04-12 jrandom
* 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)
2005-04-08 smeghead
* Added NativeBigInteger benchmark to scripts/i2pbench.sh.
2005-04-08 smeghead
* Security improvements to TrustedUpdate: signing and verification of the
version string along with the data payload for signed update files
(consequently the positions of the DSA signature and version string fields
have been swapped in the spec for the update file's header); router will
no longer perform a trusted update if the signed update's version is lower
than or equal to the currently running router's version.
* Added two new CLI commands to TrustedUpdate: showversion, verifyupdate.
* Extended TrustedUpdate public API for use by third party applications.
* 2005-04-06 0.5.0.6 released
2005-04-05 jrandom
* Retry I2PTunnel startup if we are unable to build a socketManager for a
client or httpclient tunnel.
* Add some basic sanity checking on the I2CP settings (thanks duck!)
2005-04-05 jrandom
* After a successfull netDb search for a leaseSet, republish it to all of
the peers we have tried so far who did not give us the key (up to 10),
rather than the old K closest (which may include peers who had given us
the key)
* Don't wait 5 minutes to publish a leaseSet (duh!), and rather than
republish it every 5 minutes, republish it every 3. In addition, always
republish as soon as the leaseSet changes (duh^2).
* Minor fix for oddball startup race (thanks travis_bickle!)
* Minor AES update to allow in-place decryption.
2005-04-03 jrandom
* EepGet fix for open-ended HTTP fetches (such as the news.xml
feeding the NewsFetcher)
2005-04-01 jrandom
* Allow editing I2PTunnel server instances with five digit ports
(thanks nickless_head!)
* More NewsFetcher debugging for reported weirdness
2005-04-01 jrandom
* Fix to check for missing news file (thanks smeghead!)
* Added destination display CLI:
java -cp lib/i2p.jar net.i2p.data.Destination privKeyFilename
* Added destination display to the web interface (thanks pnspns)
* Installed CIA backdoor
* 2005-03-29 0.5.0.5 released
2005-03-29 jrandom
* Decreased the initial RTT estimate to 10s to allow more retries.
* Increased the default netDb store replication factor from 2 to 6 to take
into consideration tunnel failures.
* Address some statistical anonymity attacks against the netDb that could
be mounted by an active internal adversary by only answering lookups for
leaseSets we received through an unsolicited store.
* Don't throttle lookup responses (we throttle enough elsewhere)
* Fix the NewsFetcher so that it doesn't incorrectly resume midway through
the file (thanks nickster!)
* Updated the I2PTunnel HTML (thanks postman!)
* Added support to the I2PTunnel pages for the URL parameter "passphrase",
which, if matched against the router.config "i2ptunnel.passphrase" value,
skips the nonce check. If the config prop doesn't exist or is blank, no
passphrase is accepted.
* Implemented HMAC-SHA256.
* Enable the tunnel batching with a 500ms delay by default
* Dropped compatability with 0.5.0.3 and earlier releases
2005-03-26 jrandom
* Added some error handling and fairly safe to cache data to the streaming
lib (good call Tom!)
2005-03-25 jrandom
* Fixed up building dependencies for the routerconsole on some more
aggressive compilers (thanks polecat!)
* 2005-03-24 0.5.0.4 released
2005-03-23 jrandom
* Added more intelligent version checking in news.xml, in case we have a
version newer than the one specified.
2005-03-23 jrandom
* Added support for Transfer-Encoding: chunked to the EepGet, so that the
cvsweb.cgi doesn't puke on us.
2005-03-23 Connelly
* Fixed Bugzilla Bug #99 in the SAM Bridge, which caused pending
stream send data to not be sent if STREAM CLOSE is issued too fast.
2005-03-23 jrandom
* Implemented the news fetch / update policy code, as configurated on
/configupdate.jsp. Defaults are to grab the news every 24h (or if it
doesn't exist yet, on startup). No action is taken however, though if
the news.xml specifies that a new release is available, an option to
update will be shown on the router console.
* New initialNews.xml delivered with new installs, and moved news.xml out
of the i2pwww module and into the i2p module so that we can bundle it
within each update.
2005-03-23 jrandom
* New /configupdate.jsp page for controlling the update / notification
process, as well as various minor related updates. Note that not all
options are exposed yet, and the update detection code isn't in place
in this commit - it currently says there is always an update available.
* New EepGet component for reliable downloading, with a CLI exposed in
java -cp lib/i2p.jar net.i2p.util.EepGet url
* Added a default signing key to the TrustedUpdate component to be used
for verifying updates. This signing key can be authenticated via
gpg --verify i2p/core/java/src/net/i2p/crypto/TrustedUpdate.java
* New public domain SHA1 implementation for the DSA code so that we can
handle signing streams of arbitrary size without excess memory usage
(thanks P.Verdy!)
* Added some helpers to the TrustedUpdate to work off streams and to offer
a minimal CLI:
TrustedUpdate keygen pubKeyFile privKeyFile
TrustedUpdate sign origFile signedFile privKeyFile
TrustedUpdate verify signedFile
2005-03-22 smeghead
* New TrustedUpdate component for signing/verifying files with a DSA
signature.
2005-03-21 jrandom
* Fixed the tunnel fragmentation handler to deal with multiple fragments
in a single message properly (rather than release the buffer into the
cache after processing the first one) (duh!)
* Added the batching preprocessor which will bundle together multiple
small messages inside a single tunnel message by delaying their delivery
up to .5s, or whenever the pending data will fill a full message,
whichever comes first. This is disabled at the moment, since without the
above bugfix widely deployed, lots and lots of messages would fail.
* Within each tunnel pool, stick with a randomly selected peer for up to
.5s before randomizing and selecting again, instead of randomizing the
pool each time a tunnel is needed.
* 2005-03-18 0.5.0.3 released
2005-03-18 jrandom
* Minor tweak to the timestamper to help reduce small skews
* Adjust the stats published to include only the relevent ones
* Only show the currently used speed calculation on the profile page
* Allow the full max # resends to be sent, rather than piggybacking the
RESET packet along side the final resend (duh)
* Add irc.postman.i2p to the default list of IRC servers for new installs
* Drop support for routers running 0.5 or 0.5.0.1 while maintaining
backwards compatability for users running 0.5.0.2.
2005-03-18 jrandom
* Eepproxy Fix for corrupted HTTP headers (thanks nickster!)
* Fixed case sensitivity issues on the HTTP headers (thanks duck!)
2005-03-17 jrandom
* 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!)
2005-03-16 jrandom
* 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!)
2005-03-14 jrandom
* 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
2005-03-08 jrandom
* More aggressively adjust the clock
2005-03-07 jrandom
* Fix the HTTP response header filter to allow multiple headers with the
same name (thanks duck and spotteri!)
* 2005-03-06 0.5.0.2 released
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.
* Properly expand the HTTP response header buffer (thanks shendaras!)
2005-03-04 jrandom
* 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 weren't cached before)
* Make sure our first send is always a SYN (duh)
* Workaround for some buggy compilers
2005-03-03 jrandom
* 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.
2005-03-02 jrandom
* Fix one substantial OOM cause (session tag manager was only dropping
tags once the critical limit was met, rather than honoring their
expiration) (duh)
* Lots of small memory fixes
* Double the allowable concurrent outstanding tunnel build tasks (20)
2005-03-01 jrandom
* 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.
2005-02-27 jrandom
* Don't rerequest leaseSets if there are already pending requests
* Reverted the insufficiently tested caching in the DSA/SHA1 impl, and
temporary disabled the streaming lib packet caching.
* Reduced the resend RTT penalty to 10s
2005-02-26 jrandom
* Force 1.3-isms on the precompiled jsps too (thanks laberhost)
2005-02-26 jrandom
* 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"
2005-02-24 jrandom
* Throttle the number of tunnel rebuilds per minute, preventing CPU
overload under catastrophic failures (thanks Tracker and cervantes!)
* Block the router startup process until we've initialized the clock
2005-02-24 jrandom
* Cache temporary memory allocation in the DSA's SHA1 impl, and the packet
data in the streaming lib.
* Fixed a streaming lib bug where the connection initiator would fail the
stream if the ACK to their SYN was lost.
2005-02-23 jrandom
* Now that we don't get stale SAM sessions, it'd be nice if we didn't
get stale tunnel pools, don't you think?
* 2005-02-23 0.5.0.1 released
2005-02-22 jrandom
* 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!)
2005-02-22 jrandom
* Temporary workaround for the I2CP disconnect bug (have the streaminglib
try to automatically reconnect on accept()/connect(..)).
* Loop check for expired lease republishing (just in case)
2005-02-22 jrandom
* 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.
2005-02-20 jrandom
* 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)
2005-02-20 jrandom
* 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.
2005-02-19 jrandom
* 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!)
* 2005-02-18 0.5 released
2005-02-17 jrandom
* If the clock is adjusted during a job run, don't act as if the job took
negative time.
2005-02-17 jrandom
* Included the GPL'ed susimail 0.13 by default (thanks susi23!)
2005-02-17 jrandom
* 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
2005-02-16 jrandom
* 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")
2005-02-16 jrandom
* (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 than 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!)
2005-02-10 smeghead
* 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.
2005-02-09 duck
* Allow an unneeded newline in the SAM client connection without
disconnecting.
2005-02-07 jrandom
* Fixed a race in the streaming lib's delayed flush algorithm (thanks anon!)
2005-02-06 Sugadude
* Added a filter to the addressbook to remove entries that dont end in ".i2p"
2005-02-03 smeghead
* Added Ant buildfile in apps/fortuna for creating a custom Fortuna PRNG jar
library from GNU Crypto's CVS HEAD sources.
2005-01-26 smeghead
* 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++).
2005-01-26 smeghead
* Added a couple of scripts, i2ptest.sh and i2pbench.sh, to manage the core
tests and benchmarks.
* Routerconsole now builds under gcj 3.4.3.
* Corrected divide by zero error in TunnelId class under gcj (jrandom++).
2005-01-25 smeghead
* Tweaked some classes to enable gcj 3.4.3 to compile the router and
supporting apps (except for the routerconsole which is still being
investigated).
2005-01-24 smeghead
* C#-ification of sam-sharp: interface greatly simplified using delegates
and events; SamBaseEventHandler provides basic implementation and helper
methods but is now optional.
* NAnt buildfile and README added for sam-sharp.
2005-01-23 smeghead
* Port the java SAM client library to mono/C# and released into the
public domain. The 0.1 version of this port is available in CVS as
i2p/apps/sam/csharp/src/I2P.SAM.Client. The other nonfunctional C#
library has been removed.
2005-01-21 Jhor
* Updated jbigi build scripts for OSX.
2005-01-21 jrandom
* Added support for OSX to the NativeBigInteger code so that it will look
in the classpath for libjbigi-osx-none.jnilib. At the moment, that file
is not bundled with the shipped jbigi.jar yet though.
2005-01-18 jrandom
* Increased the max # session tags maintained and decreased slightly the
period over which they are gathered.
2005-01-17 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.
2005-01-15 cervantes
* 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
2005-01-15 jrandom
* 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 0.4.2.6 released
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
2005-01-05 jrandom
* 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.
2004-12-31 ragnarok
* Integrated latest addressbook changes (2.0.3) which include support for
deploying as a .war file with no existing addressbook configuration.
* Updated main build process to bundle the addressbook.war in the
i2pinstall.jar and i2pupdate.zip.
2004-12-31 jrandom
* Speling fxi (thanks digum!)
* Bugfix for the I2PTunnel web interface so that it now properly launches
newly added tunnels that are defined to be run on startup (thanks ugha!)
2004-12-30 jrandom
* 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).
2004-12-29 jrandom
* Imported Ragnarok's addressbook source (2.0.2) which is built but not
deployed in the i2pinstall.jar/i2pupdate.zip (yet).
* Don't treat connection inactivity closure as a connection error.
2004-12-29 jrandom
* 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.
2004-12-28 jrandom
* Cleaned up the resending and choking algorithm in the streaming lib.
* Removed the read timeout override for I2PTunnel's httpclient, allowing
it to use the default for the streaming lib.
* Revised ack triggers in the streaming lib.
* Logging.
* 2004-12-21 0.4.2.5 released
2004-12-21 jrandom
* Track a new stat for expired client leases (client.leaseSetExpired).
2004-12-21 jrandom
* 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!)
2004-12-20 jrandom
* No longer do a blocking DNS lookup within the jobqueue (thanks mule!)
* Set a 60s dns cache TTL, instead of 0s. Most users who used to use
dyndns/etc now just use IP autodetection, so the old "we need ttl=0"
reasoning is gone.
2004-12-19 jrandom
* Fix for a race on startup wrt the new stats (thanks susi!)
2004-12-19 jrandom
* Added three new stats - router.activePeers, router.fastPeers, and
router.highCapacityPeers, updated every minute
2004-12-19 jrandom
* 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).
2004-12-19 scintilla
* Convert native jcpuid code from C++ to C. This should alleviate build
problems experienced by some users.
* 2004-12-18 0.4.2.4 released
2004-12-16 jrandom
* 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.
2004-12-16 jrandom
* 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
2004-12-15 jrandom
* 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.
2004-12-14 jrandom
* 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.
2004-12-14 jrandom
* 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
2004-12-13 jrandom
* 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)
2004-12-11 jrandom
* 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
2004-12-11 jrandom
* 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
* 2004-12-08 0.4.2.3 released
2004-12-08 jrandom
* Revised the buffering when reading from the SAM client and writing
to the stream. Also added a thread (sigh) so we don't block the
SAM client from giving us more messages for abnormally long periods
of time.
* Display the router version in the logs on startup (oft requested)
* Fix a race during the closing of a messageOutputStream
2004-12-06 jrandom
* Don't do a 'passive flush' while there are already outbound messages
unacked.
* Show the reseed link if up to 10 peers profiles are active (thanks
dburton!)
2004-12-06 jrandom
* Don't propogate streaming connection failures out to the SAM bridge as
fatal errors.
* Dont barf on repeated I2CP closure.
2004-12-05 jrandom
* Explicitly use "127.0.0.1" to bind the I2CP listener, not the JVM's
getLocalhost call
2004-12-05 jrandom
* Default the I2CP listener to localhost only, unless overridden by
i2cp.tcp.bindAllInterfaces=true (thanks dm!)
* More SAM fixes for things recently broken (whee)
2004-12-05 jrandom
* Fix the recently broken SAM bridge (duh)
* Add a new pair of SAM apps - net.i2p.sam.client.SAMStreamSink and
net.i2p.sam.client.SAMStreamSend, mirroring the streaming lib's
StreamSink and StreamSend apps for transferring files.
* Make the passive flush timer fire more frequently.
2004-12-05 jrandom
* Fixed some links in the console (thanks ugha!) and the javadoc
(thanks dinoman!)
* Fix the stream's passive flush timer (oh, its supposed to work?)
2004-12-03 jrandom
* 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.
2004-12-01 jrandom
* Fix for a race in the streaming lib as caused by some odd SAM activity
* 2004-12-01 0.4.2.2 released
2004-12-01 jrandom
* Fixed a stupid typo that inadvertantly allowed persistent HTTP
connections to work (thanks duck!)
* Make sure we override the inactivity timeout too
* 2004-12-01 0.4.2.1 released
2004-12-01 jrandom
* Strip out any of the Accept-* HTTP header lines, and always make sure to
include the forged User-agent header.
* Adjust the default read timeout on the eepproxy to 60s, unless
overridden.
* Minor tweak on stream shutdown.
2004-11-30 jrandom
* Render the burst rate fields on /config.jsp properly (thanks ugha!)
* Build in a simple timeout to flush data queued into the I2PSocket but
not yet flushed.
* Don't explicitly flush after each SAM stream write, but leave it up to
the [nonblocking] passive flush.
* Don't whine about 10-99 connection events occurring in a second
* Don't wait for completion of packets that will not be ACKed (duh)
* Adjust the congestion window, even if the packet was resent (duh)
* Make sure to wake up any blocking read()'s when the MessageInputStream
is close()ed (duh)
* Never wait more than the disconnect timeout for a write to complete
2004-11-29 jrandom
* Minor fixes to avoid unnecessary errors on shutdown (thanks susi!)
2004-11-29 jrandom
* Reduced contention for local client delivery
* Drop the new code that munges the wrapper.config. Instead, updates that
need to change it will include their own wrapper.config in the
i2pupdate.zip, overwriting the existing file. If the file
"wrapper.config.updated" is included, it is deleted at first opportunity
and the router shut down, displaying a notice that the router must be
started again cleanly to allow the changes to the wrapper.config to take
effect.
* Properly stop accept()ing I2PSocket connections if we close down the
session (duh).
* Make sure we cancel any outstanding Packets in flight when a connection
is terminated (thanks susi!)
* Split up the I2PTunnel closing a little further.
2004-11-28 jrandom
* Accept IP address detection changes with a 2-out-of-3 minimum.
* As long as the router is up, keep retrying to bind the I2CP listener.
* Decrease the java service wrapper ping frequency to once every 10
minutes, rather than once every 5 seconds.
2004-11-27 jrandom
* Some cleanup and bugfixes for the IP address detection code where we
only consider connections that have actually sent and received messages
recently as active, rather than the mere presence of a TCP socket as
activity.
2004-11-27 jrandom
* Removed the I2PTunnel inactivity timeout thread, since the new streaming
lib can do that (without an additional per-connection thread).
* Close the I2PTunnel forwarder threads more aggressively
2004-11-27 jrandom
* Fix for a fast loop caused by a race in the new streaming library (thanks
DrWoo, frontier, pwk_, and thetower!)
* Minor updates to the SimpleTimer and Connection to help track down a
high CPU usage problem (dumping debug info to stdout/wrapper.log if too
many events/tasks fire in a second)
* Minor fixes for races on client disconnects (causing NPEs)
* 2004-11-26 0.4.2 released
2004-11-26 jrandom
* Enable the new streaming lib as the default. That means, for any
substantial definition, it is NOT BACKWARDS COMPATIBLE.
2004-11-25 jrandom
* 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)
2004-11-22 jrandom
* Update to the SAM bridge to reduce some unnecessary memory allocation.
* New stat to keep track of slow jobs (ones that take more than a second
to excute). This is published in the netDb as jobQueue.jobRunSlow
2004-11-21 jrandom
* Update the I2PTunnel web interface to include an option for the new
streaming lib (which is ignored until the 0.4.2 release).
* Revised the I2PTunnel web interface to keep the I2CP options of client
and httpclient tunnels in sync, as they all share the same I2CP session.
2004-11-21 jrandom
* Only allow small clock skews after the first 10 minutes of operation
(to prevent later network lag bouncing us way off course - yes, we
really need an NTP impl to balance out the network burps...)
* Revamp the I2PTunnel web interface startup process so that everything
is shown immediately, so that different pieces hanging don't hang
the rest, and other minor bugfixes.
* Take note of SAM startup error (in case you're already running a SAM
bridge...)
* Increase the bandwidth limiter burst values available to 10-60s (or
whatever is placed in /configadvanced.jsp, of course)
2004-11-21 jrandom
* Allow end of line comments in the hosts.txt and other config files,
using '#' to begin the comments (thanks susi!)
* Add support to I2PTunnel's 'client' feature for picking between multiple
target destinations (e.g. 'client 6668 irc.duck.i2p,irc.baffled.i2p')
* Add a quick link on the left hand nav to reseed if there aren't enough
known peers, as well as link to the config page if there are no active
peers. Revised config page accordingly.
2004-11-21 jrandom
* Destroy ElGamal/AES+SessionTag keys after 15 minutes of inactivity
rather that every 15 minutes, and increase the warning period in which
we refresh tags from 30s to 2 minutes.
* Bugfix for a rare problem closing an I2PTunnel stream where we'd fail
to close the I2PSocket (leaving it to timeout).
2004-11-19 jrandom
* Off-by-one fix to the tunnel pool management code, along side some
explicit initialization. This can affect clients whose lengths are
shorter than the router's default (thanks duck!)
2004-11-17 jrandom
* Fix to propogate i2psocket options into the SAM bridge correctly (thanks
Ragnarok!)
2004-11-17 jrandom
* Minor logging update.
2004-11-16 jrandom
* Clean up the propogation of i2psocket options so that various streaming
libs can honor them more precisely
2004-11-16 jrandom
* Minor logging update
2004-11-14 jrandom
* Fix a long standing leak in I2PTunnel (hanging on to i2psocket objects)
* Fix a leak injected into the SimpleTimer
* Fix a race condition in the tunnel message handling
2004-11-13 jrandom
* Added throttles on how many I2PTunnel client connections we open at once
* Replaced some buffered streams in I2PTunnel with unbuffered streams, as
the streaming library used should take care of any buffering.
* Added a cache for some objects used in I2PTunnel, especially useful when
there are many short lived connections.
* Trimmed the SimpleTimer's processing a bit
2004-11-10 jrandom
* Allow loading the (mini)streaming connection options from the
environment.
* More defensive programming in the DSA implementation.
2004-11-08 jrandom
* 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
2004-11-08 jrandom
* Make the SAM bridge more resiliant to bad handshakes (thanks duck!)
* 2004-11-06 0.4.1.4 released
2004-11-06 jrandom
* Expose a drop down on the /configclients.jsp to enter the outbound
tunnel depth.
* Improved *hosts.txt loading
* Explicitly override the JVM's timezone settings to use GMT so that
any client applications which use timezones won't leak sensitive
data (thanks gott!)
* Bundle sam.jar in the update (thanks duck!)
2004-11-06 jrandom
* Fix for a long standing synchronization bug in the SDK that in rare
instances can add a few seconds of lag.
2004-11-05 jrandom
* Bugfixes and unit tests for the SAM bridge to handle quoted message
parameters, verify proper operation after multiple session lifetimes,
as well as some synchronization problems.
* New properties method on the DataHelper class.
* Address a race on fast disconnecting clients
2004-11-02 jrandom
* Fix for a long standing synchronization bug in the JobQueue (and added
some kooky flags to make sure it stays dead)
* Update the ministreaming lib to force mode=guaranteed if the default
lib is used, and mode=best_effort for all other libs.
2004-11-02 jrandom
* Fixed up the configuration overrides for the streaming socket lib
integration so that it properly honors env settings.
* More memory usage streamlining (last major revamp for now, i promise)
2004-11-01 jrandom
* Increase the tunnel test timeout rapidly if our tunnels are failing.
* Honor message expirations for some tunnel jobs that were prematurely
expired.
* Streamline memory usage with temporary object caches and more efficient
serialization for SHA256 calculation, logging, and both I2CP and I2NP
message handling.
* Fix some situations where we forward messages too eagerly. For a
request at the tunnel endpoint, if the tunnel is inbound and the target
is remote, honor the message by tunnel routing the data rather than
sending it directly to the requested location.
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
2004-10-29 jrandom
* Strip the Referer, Via, and From headers completely, rather than
inserting a bogus value ("i2p"). This should help with the use of
SnipSnap and Geeklog (thanks nickster and DrWoo!)
2004-10-27 jrandom
* Fix a strange race condition on i2cp client disconnect.
* win98 startup fixes (thanks tester-1 and ardvark!)
* include build scripts for the new streaming lib (which is NOT ready
for use yet, but you can hack around with it)
2004-10-24 jrandom
* 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 to instantiate.
2004-10-23 jrandom
* Minor ministreaming lib refactoring to simplify integration of the full
streaming lib.
* Minor bugfixes to data structure serialization.
* 2004-10-18 0.4.1.3 released
2004-10-18 jrandom
* Allow sending messages with a section of a byte array.
* Reduced stats published.
2004-10-17 jrandom
* Don't b0rk on whitespace in the router address.
2004-10-16 jrandom
* More aggressively reduce the capacity of peers if their tunnels are
failing so that we move off them quicker.
* Simplify some data structure serialization for reuse in the streaming
lib, as well as add support for signing and verifying partial byte
arrays.
* Logging updates
2004-10-16 jrandom
* Increased the default minimum tunnel test time to 5 seconds, since we
still see the occational message processing time spike to 2 seconds.
* Update the SimpleTimer to allow rescheduling a task thats already
queued (useful for the new streaming lib).
2004-10-15 jrandom
* Replaced old minimum tunnel test timeout of 1s with a configurable
value (router.config property "router.tunnelTestMinimum", with the
default of 2s).
2004-10-14 jrandom
* Tunnel rejection is no longer a sign of an overwhelmingly loaded
peer, so don't use it as a key point of the IsFailing calculator.
We still use it as a key point of the Capacity calculator, however.
2004-10-14 jrandom
* Allow for a configurable tunnel "growth factor", rather than trying
to achieve a steady state. This will let us grow gradually when
the router is needed more, rather than blindly accepting the request
or arbitrarily choking it at an averaged value. Configure this with
"router.tunnelGrowthFactor" in the router.config (default "1.5").
* Adjust the tunnel test timeouts dynamically - rather than the old
flat 30s (!!!) timeout, we set the timeout to 2x the average tunnel
test time (the deviation factor can be adjusted by setting
"router.tunnelTestDeviation" to "3.0" or whatever). This should help
find the 'good' tunnels.
* Added some crazy debugging to try and track down an intermittent hang.
2004-10-13 jrandom
* Fix the probabalistic tunnel reject (we always accepted everything,
since the docs on java.util.Random.nextDouble() are wrong..)
* Fixed a race on startup (thanks Quadn!)
2004-10-12 jrandom
* Disable the probabalistic drop by default (enable via the router config
property "tcp.dropProbabalistically=true")
* Disable the actual watchdog shutdown by default, but keep track of more
variables and log a lot more when it occurs (enable via the router
config property "watchdog.haltOnHang=true")
* Implement some tunnel participation smoothing by refusing requests
probabalistically as our participating tunnel count exceeds the previous
hour's, or when the 10 minute average tunnel test time exceeds the 60
minute average tunnel test time. The probabilities in both cases are
oldAverage / #current, so if you're suddenly flooded with 200 tunnels
and you had previously only participated in 50, you'll have a 25% chance
of accepting a subsequent request.
* 2004-10-10 0.4.1.2 released
2004-10-10 cervantes
* Update the I2PTunnel HTTP proxy to strip out the i2paddresshelper from
the request.
2004-10-09 jrandom
* Added a watchdog timer to do some baseline liveliness checking to help
debug some odd errors.
* Added a pair of summary stats for bandwidth usage, allowing easy export
with the other stats ("bw.sendBps" and "bw.receiveBps")
* Trimmed another memory allocation on message reception.
2004-10-08 jrandom
* Revamp the AESInputStream so it doesn't allocate any temporary objects
during its operation.
2004-10-08 jrandom
* Don't kill the establisher threads during a soft restart.
* Attempt to validate the peer's routerInfo earlier during handshaking.
* Revamp the AESOutputStream so it doesn't allocate any temporary objects
during its operation.
2004-10-07 jrandom
* Reimplement the I2NP reading with less temporary memory allocation.
There is still significant GC churn, especially under load, but this
should help.
* Catch some oddball errors in the transport (message timeout while
establishing).
2004-10-07 jrandom
* Expire queued messages even when the writer is blocked.
* Reimplement most of the I2NP writing with less temporary memory
allocations (I2NP reading still gobbles memory).
2004-10-06 jrandom
* Implement an active queue management scheme on the TCP transports,
dropping messages probabalistically as the queue fills up. The
estimated queue capacity is determined by the rate at which messages
have been sent to the peer (averaged at 1, 5, and 60m periods). As
we exceed 1/2 of the estimated capacity, we drop messages throughout
the queue probabalistically with regards to their size. This is based
on RFC 2309's RED, with the minimum threshold set to 1/2 the
estimated connection capacity. We may want to consider using a send
rate and queue size measured across all connections, to deal with our
own local bandwidth saturation, but we'll try the per-con metrics first.
2004-10-06 jrandom
* Enable explicit disabling of the systray entirely for windows machines
with strange configurations: add -Dsystray.disable=true to the java
command line. (thanks mihi!)
2004-10-05 jrandom
* Allow peers on the same LAN to communicate with each other safely even
when they cannot talk to each other through the external address.
2004-10-05 jrandom
* Display how much time is left before the graceful shutdown is complete.
* Debug some improperly failed messages on timeout or disconnection.
2004-10-05 jrandom
* Don't go into a fast busy if an I2PTunnel 'server' is explicitly killed
(thanks mule!)
* Handle some more error conditions regarding abruptly closing sockets
(thanks Jonva!)
2004-10-04 jrandom
* Update the shitlist to reject a peer for an exponentially increasing
period of time (with an upper bounds of an hour).
* Various minor stat and debugging fixes
2004-10-03 jrandom
* Add a new stat logging component to optionally dump the raw stats to
disk as they are generated, rather than rely upon the summarized data.
By default, this is off, but the router property "stat.logFilters" can
be set to a comma delimited list of stats (e.g. "client.sendAckTime")
which will be written to the file "stats.log" (or whatever the property
"stat.logFile" is set to). This can also log profile related stats,
such as "dbResponseTime" or "tunnelTestResponseTime".
2004-10-02 jrandom
* Assure that we quickly fail messages bound for shitlisted peers.
* Address a race on startup where the first peer contacted could hang the
router (thanks Romster!)
* Only whine about an intermittent inability to query the time server once
2004-10-02 jrandom
* Command line utility to verify a peer's reachability - simply run
net.i2p.router.transport.tcp.ConnectionHandler hostname port# and it
will print out whether that peer is reachable or not (using a simple
verification handshake).
* 2004-10-01 0.4.1.1 released
2004-10-01 jrandom
* Handle partial reseeds, caused by seeds going away before the download
completes (thanks Sugadude!)
2004-10-01 jrandom
* Explicitly refuse IPv6 addresses, since only some peers support
them and we want fully reachable peers.
2004-10-01 jrandom
* Additional error handling for a variety of transport layer errors.
* 2004-09-30 0.4.1 released (not backwards compatible)
2004-09-30 jrandom
* Bundle the configuration necessary to run an eepsite out of the box
with Jetty - simply edit ./eepsite/docroot/index.html and give people
the key listed on the I2PTunnel configuration page, and its up.
* Router console cleanup, and some (off by default) tunnels -
smtp.postman.i2p (port 7659), pop.postman.i2p (port 7660), and
irc.baffled.i2p (port 7661)
2004-09-29 jrandom
* Always wipe the Jetty work directory on startup, so that web updates
are reflected immediately (Jetty does not honor the cache across
multiple executions)
2004-09-27 jrandom
* Limit the number of connection tags saved to 10,000. This is a huge
limit, but consumes no more than 1MB of RAM. For now, we drop them
randomly after reaching that size, forcing those dropped peers to use
a full DH negotiation.
* HTML cleanup in the console.
2004-09-26 jrandom
* Complete rewrite of the TCP transport with IP autodetection and
low CPU overhead reconnections. More concise connectivity errors
are listed on the /oldconsole.jsp as well. The IP autodetection works
by listening to the first person who tells you what your IP address is
when you have not defined one yourself and you have no other TCP
connections.
* Update to the I2NP message format to add transparent verification at
the I2NP level (beyond standard TCP verification).
* Remove a potential weakness in our AESEngine's safeEncrypt and safeDecrypt
implementation (rather than verifying with E(H(key)), we now verify with
E(H(iv))).
* The above changes are NOT BACKWARDS COMPATIBLE.
* Removed all of the old unused PHTTP code.
* Refactor various methods and clean up some javadoc.
2004-09-21 jrandom
* Have two tiers of hosts.txt files - the standard "hosts.txt" and
the new "userhosts.txt". Updates to I2P will only overwrite the former,
but values stored in the later take precedence. Both are queried on
lookup.
2004-09-16 jrandom
* Refactor the TCP transport to deal with changing identities gracefully,
and to prevent some wasted effort by keeping track of what host+port
combinations we are connected to (rather than just the identities). Also
catch a few configuration errors earlier.
* Removed no longer relevent methods from the Transport API that were
exposing ideas that probably shouldn't be exposed.
* Removed the 0.4.0.1 specific files from i2pupdate.zip (relating to script
updates)
2004-09-13 jrandom
* Update for the SDK reconnection to deal with overflow.
* Web improvements (@ not # on the /logs.jsp [thanks ugha!] and fixed the
rounding on lifetime bandwidth used [thanks gott!]).
* 2004-09-08 0.4.0.1 released
2004-09-08 jrandom
* Updated the "Active:" peer count to display the # of connections as well
as the number of recently active router identities.
* Implement some basic updating code - on startup, if there is a file named
"i2pupdate.zip" in the I2P installation directory, extract it, delete it,
then restart.
* Added an ugly little script to allow launching the router on win9x
machines without a dos box (using javaw to run a .bat file).
* Logging updates.
* Updated VERSION constants to 0.4.0.1
2004-09-08 hypercubus
* Bugfix: Running the installer as a non-privileged user on Red Hat (and
hopefully any other affected *nix systems) now properly discards non-
essential directories after installation.
* Support for Win9x in the installer and postinstall.bat.
* Changed the name of the default installation directory on all platforms
from "I2P" to "i2p" in the installer.
* Changed "wrapper.conf" to "wrapper.config" for naming consistency with the
other configuration files.
2004-09-07 cervantes:
* Proxy recursion disabled by default (strict)
* Password Authentication for session commands
* Support for http://path?i2paddresshelper=BASE64
* Support for http://i2p/BASE64/path syntax
2004-09-07 jrandom
* Make sure that peers placed in the 'fast' group are ones we both know
how to reach and have been able to reach recently. These peers may
still be placed in the 'high capacity' group however (though that group
is only queried if the 'fast' group is too small)
* Include some updates to the ProgileOrganizer's CLI.
2004-09-07 jrandom
* Disable the timestamper by default for all applications except the router
(enable via -Dtime.disabled=false)
* Simplify the retrieval of the full destination with text based browsers.
* Bundle the updated wrapper.config and hosts.txt in the i2pupdate.tar.bz2
2004-09-07 jrandom
* Write the native libraries to the current directory when they are loaded
from a resource, and load them from that file on subsequent runs (in
turn, we no longer *cough* delete the running libraries...)
* Added support for a graceful restart.
* Added new pseudo-shutdown hook specific to the router, allowing
applications to request tasks to be run when the router shuts down. We
use this for integration with the service manager, since otherwise a
graceful shutdown would cause a timeout, followed by a forced hard
shutdown.
* Made the capacity calculator a bit more dynamic by not outright ignoring
the otherwise valid capacity data for a period with a single rejected
tunnel (except for the 10 minute period). In addition, peers with an
equal capacity are ordered by speed rather than by their hashes.
* Cleaned up the SimpleTimer, addressing some threading and synchronization
issues.
* When an I2PTunnel client or httpclient is explicitly closed, destroy the
associated session (unless there are other clients using it), and deal
with a closed session when starting a new I2PTunnel instance.
* Refactoring and logging.
2004-09-06 jrandom
* Address a race condition in the key management code that would manifest
itself as a corrupt router identity.
* Properly clear old transport addresses from being displayed on the old
console after soft restarts.
* Properly refuse to load the client applications more than once in the
same JVM.
* Added support for a graceful restart (a graceful shutdown followed by a
full JVM restart - useful for restarting client apps).
* More defensive programming, HTML cleanup, logging
* wrapper.config cleanup of duplicate lines
2004-09-04 jrandom
* Added some basic guards to prevent multiple instances from running.
Specifically, a file "router.ping" in the install directory which is
written to once a minute - if that file exists and has been modified
within the last minute, refuse to start up. In turn, adjust the
service wrapper to wait a minute before restarting a crashed JVM.
* Create a "work" directory in the I2P install dir which Jetty will
use for all of its temporary files.
* Tell the browser not to cache most of the router console's pages.
2004-09-04 jrandom
* Update the SDK to automatically reconnect indefinitely with an
exponential delay on retries (capped at 5 minutes).
* 2004-09-03 0.4 released
2004-09-03 jrandom
* Updated default wrapper.config to deal with the hard restart option
* Include the history.txt in the /help.jsp page
* HTML updates (wrapper.log, and no more unix scripts)
* Updated VERSION constants to 0.4
2004-09-03 hypercubus
* Bugfix: Installer launches postinstall.bat on WinNT/2K properly.
* Temporarily removed install_i2p_service_unix and
uninstall_i2p_service_unix from distribution packages.
* postinstall.bat/postinstall.sh cleans installation directory of all files
not applicable to the host OS.
2004-09-03 oOo
* Added some filters to the HTTP request, replacing the User-Agent,
Referrer, Via, and From headers, which helps until we have a more
comprehensive filtering system.
2004-09-03 jrandom
* Disabled the old listener on port 7655.
2004-09-02 jrandom
* Cleaned up the base build.xml, adding a new target ("updater") which
builds the file i2pupdate.tar.bz2 which can be safely extracted over
existing installs.
2004-xx-xx jrandom
* Implemented the new web architecture and router console
* Implemented I2PTunnel web interface, and revamped startup process.
* Revamped peer selection code to address skew.

* Integrated Iakin's jcpuid library and jbigi update, with modifications.
2004-xx-xx hypercubus
