* Add auto-detect IP/Port to NTCP. When enabled on config.jsp,
SSU will notify/restart NTCP when the external address changes.
Now you can enable inbound TCP without a static IP or dyndns service.
* First pass on EepGet and ReseedHandler improvements,
please avoid use on routers which matter!
* Give EepGet ability of downloading into an OutputStream,
such as the ByteArrayOutputStream of ReseedHandler.
* Detect failure to reseed better, report it persistently
and more verbosely, provide a link to logs
and suggest manual reseed.
* Modify ReseedHandler to query the "i2p.reseedURL" property from I2PAppContext
instead of System, so setting a reseed URL in advanced configuration has effect.
* Clean out obsolete reseed code from ConfigNetHandler.

* Removed the status display from the console, as its more confusing
than informative (though the content is still displayed in the HTML)
2006-07-18 jrandom
* Add a failsafe to the NTCP transport to make sure we keep
pumping writes when we should.
* Properly reallow 16-32KBps routers in the default config
(thanks Complication!)
* Improve the multitransport shitlisting (thanks Complication!)
* Allow routers with a capacity of 16-32KBps to be used in tunnels under
the default configuration (thanks for the stats Complication!)
* Properly allow older router references to load on startup
(thanks bar, Complication, et al!)
* Add a new "i2p.alwaysAllowReseed" advanced config property, though
hopefully today's changes should make this unnecessary (thanks void!)
* Improved NTCP buffering
* Close NTCP connections if we are too backlogged when writing to them
* New NIO-based tcp transport (NTCP), enabled by default for outbound
connections only. Those who configure their NAT/firewall to allow
inbound connections and specify the external host and port
(dyndns/etc is ok) on /config.jsp can receive inbound connections.
SSU is still enabled for use by default for all users as a fallback.
* Substantial bugfix to the tunnel gateway processing to transfer
messages sequentially instead of interleaved
* Renamed GNU/crypto classes to avoid name clashes with kaffe and other
GNU/Classpath based JVMs
* Adjust the Fortuna PRNG's pooling system to reduce contention on
refill with a background thread to refill the output buffer
* Add per-transport support for the shitlist
* Add a new async pumped tunnel gateway to reduce tunnel dispatcher
contention
* Correct a misnamed property in SummaryHelper.java
to avoid confusion
* Make the maximum allowance of our own concurrent
tunnel builds slightly adaptive: one concurrent build per 6 KB/s
within the fixed range 2..10
* While overloaded, try to avoid completely choking our own build attempts,
instead prefer limiting them to 1
* Adjust how we pick high capacity peers to allow the inclusion of fast
peers (the previous filter assumed an old usage pattern)
* New set of stats to help track per-packet-type bandwidth usage better
* Cut out the proactive tail drop from the SSU transport, for now
* Reduce the frequency of tunnel build attempts while we're saturated
* Don't drop tunnel requests as easily - prefer to explicitly reject them
* Include a combined send/receive graph (good idea cervantes!)
* Proactively drop inbound tunnel requests probabalistically as the
estimated queue time approaches our limit, rather than letting them all
through up to that limit.
* Process inbound tunnel requests more efficiently
* Proactively drop inbound tunnel requests if the queue before we'd
process it in is too long (dynamically adjusted by cpu load)
* Adjust the tunnel rejection throttle to reject requeusts when we have to
proactively drop too many requests.
* Display the number of pending inbound tunnel join requests on the router
console (as the "handle backlog")
* Include a few more stats in the default set of graphs
* Fix during the ssu handshake to avoid an unnecessary failure on
packet retransmission (thanks ripple!)
* Fix during the SSU handshake to use the negotiated session key asap,
rather than using the intro key for more than we should (thanks ripple!)
* Fixes to the message reply registry (thanks Complication!)
* More comprehensive syndie banning (for repeated pushes)
* Publish the router's ballpark bandwidth limit (w/in a power of 2), for
testing purposes
* Put a floor back on the capacity threshold, so too many failing peers
won't cause us to pick very bad peers (unless we have very few good
ones)
* Bugfix to cut down on peers using introducers unneessarily (thanks
Complication!)
* Reduced the default streaming lib message size to fit into a single
tunnel message, rather than require 5 tunnel messages to be transferred
without loss before recomposition. This reduces throughput, but should
increase reliability, at least for the time being.
* Misc small bugfixes in the router (thanks all!)
* More tweaking for Syndie's CSS (thanks Doubtful Salmon!)
* Avoid a very strange (unconfirmed) bug that people using the systray's
browser picker dialog could cause by disabling the GUI-based browser
picker.
* Cut down on subsequent streaming lib reset packets transmitted
* Use a larger MTU more often
* Allow netDb searches to query shitlisted peers, as the queries are
indirect.
* Add an option to disable non-floodfill netDb searches (non-floodfill
searches are used by default, but can be disabled by adding
netDb.floodfillOnly=true to the advanced config)
* Made the netDb search load limitations a little less stringent
* Add support for specifying the number of periods to be plotted on the
graphs - e.g. to plot only the last hour of a stat that is averaged at
the 60 second period, add &periodCount=60
* Add support for graphing the event count as well as the average stat
value (done by adding &showEvents=true to the URL). Also supports
hiding the legend (&hideLegend=true), the grid (&hideGrid=true), and
the title (&hideTitle=true).
* Removed an unnecessary arbitrary filter on the profile organizer so we
can pick high capacity and fast peers more appropriately
* Integrate basic hooks for jrobin (http://jrobin.org) into the router
console. Selected stats can be harvested automatically and fed into
in-memory RRD databases, and those databases can be served up either as
PNG images or as RRDtool compatible XML dumps (see oldstats.jsp for
details). A base set of stats are harvested by default, but an
alternate list can be specified by setting the 'stat.summaries' list on
the advanced config. For instance:
stat.summaries=bw.recvRate.60000,bw.sendRate.60000
* HTML tweaking for the general config page (thanks void!)
* Odd NPE fix (thanks Complication!)
* 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_!)
* 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).
* 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_!)
* 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)
* 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)
* 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
* 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)
* 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.
* Merge sucker into syndie with a rssimport.jsp page.
* Add getContentType() to EepGet.
* Make chunked transfer work (better) with EepGet.
* Do replaceAll("<","<") for logs.
* 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.
* 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
2005-10-07 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.
* 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 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.
* 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)
* 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
* 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.
* 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.
* 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.
* Expose the HTTP headers to EepGet status listeners
* Handle DSA key failures properly (if the signature is not invertable, it
is obviously invalid)
also, syndie now properly detects whether the remote archive can send a filtered export.zip
by examining the HTTP headers for X-Syndie-Export-Capable: true. If the remote archive
does not set that header (and neither freesites, nor apache or anything other than the ArchiveServlet will),
it uses individual HTTP requests for individual blog posts and metadata fetches.
* 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
* 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.
