* Removed the status display from the console, as its more confusing
than informative (though the content is still displayed in the HTML)
* i2psnark: Paranoid copy before writing pieces,
recheck files on completion, redownload bad pieces
* i2psnark: Don't contact tracker as often when seeding
* i2psnark: Implement retransmission of requests. This
eliminates one cause of complete stalls with a peer.
This problem is common on torrents with a small number of
active peers where there are no choke/unchokes to kickstart things.
* i2psnark: Mark a peer's requests as unrequested on disconnect,
preventing premature end game
* i2psnark: Randomize selection of next piece during end game
* i2psnark: Don't restore a partial piece to a peer that is already working on it
* i2psnark: strip ".torrent" on web page
* i2psnark: Limit piece size in generated torrent to 1MB max
* i2psnark: Fix bug where new peers would always be set to "interested"
regardless of actual interest
* i2psnark: Reduce max piece size from 10MB to 1MB; larger may have severe
memory and efficiency problems
* i2psnark: Implement basic partial-piece saves across connections
* i2psnark: Implement keep-alive sending. This will keep non-i2psnark clients
from dropping us for inactivity but also renders the 2-minute transmit-inactivity
code in i2psnark ineffective. Will have to research why there is transmit but
not receive inactivity code. With the current connection limit of 24 peers
we aren't in any danger of keeping out new peers by keeping inactive ones.
* i2psnark: Increase CHECK_PERIOD from 20 to 40 since nothing happens in 20 seconds
* i2psnark: Fix dropped chunk handling
* i2psnark: Web rate report cleanup
* i2psnark: Report cleared trackerErr immediately
* i2psnark: Add trackerErr reporting after previous success; retry more quickly
* i2psnark: Set up new connections more quickly
* i2psnark: Don't delay tracker fetch when setting up lots of connections
* i2psnark: Reduce MAX_UPLOADERS from 12 to 4
* Limit form size in SusiDNS to avoid exceeding a POST size limit on postback
* Print messages about addressbook size to give better overview
* Enable delete function in published addressbook

* 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
* Ensure that the I2PTunnel web interface won't update tunnel settings
for shared clients when a non-shared client is modified
(thanks for spotting, BarkerJr!)
* 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
* Cut down on the time that we allow a tunnel creation request to sit by
without response, and reject tunnel creation requests that are lagged
locally. Also switch to a bounded FIFO instead of a LIFO
* Threading tweaks for the message handling (thanks bar!)
* Don't add addresses to syndie with blank names (thanks Complication!)
* Further ban clearance
* 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!)
* Take out the router watchdog's teeth (don't restart on leaseset failure)
* Filter the IRC ping/pong messages, as some clients send unsafe
information in them (thanks aardvax and dust!)
* Added a simple purge and ban of syndie authors, shown as the
"Purge and ban" button on the addressbook for authors that are already
on the ignore list. All of their entries and metadata are deleted from
the archive, and the are transparently filtered from any remote
syndication (so no user on the syndie instance will pull any new posts
from them)
* More strict tunnel join throtting when congested
* 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!)
* HTML fixes in Syndie to work better with opera (thanks shaklen!)
* Give netDb lookups to floodfill peers more time, as they are much more
likely to succeed (thereby cutting down on the unnecessary netDb
searches outside the floodfill set)
* Fix to the SSU IP detection code so we won't use introducers when we
don't need them (thanks Complication!)
* Add a brief shitlist to i2psnark so it doesn't keep on trying to reach
peers given to it
* Don't let netDb searches wander across too many peers
* Don't use the 1s bandwidth usage in the tunnel participation throttle,
as its too volatile to have much meaning.
* Don't bork if a Syndie post is missing an entry.sml
* More aggressive tunnel throttling as we approach our bandwidth limit,
and throttle based off periods wider than 1 second.
* Included Doubtful Salmon's syndie stylings (thanks!)

* Adjust the jbigi.jar to use the athlon-optimized jbigi on windows/amd64
machines, rather than the generic jbigi (until we have an athlon64
optimized version)
* Switch from the bouncycastle to the gnu-crypto implementation for
SHA256, as benchmarks show a 10-30% speedup.
* Removed some unnecessary object caches
* Don't close i2psnark streams prematurely
* Made the Syndie permalinks in the thread view point to the blog view
* Disabled TCP again (since the live net seems to be doing well w/out it)
* Fix the message time on inbound SSU establishment (thanks zzz!)
* Don't be so aggressive with parallel tunnel creation when a tunnel pool
just starts up
