2007-11-26 zzz
* i2psnark: add timeout for receive inactivity
2007-11-24 zzz
* i2psnark: increase streaming lib write timeout to 240 sec and change
timeout action from "ping" to "disconect", as the fix in .30 to
honor options on outbound connections led to hung outbound connections
(bitfield never transmitted, connection never dropped)
2007-10-11 zzz
* IRC Proxy: Fix several possible anonymity holes:
- Block CTCP in NOTICE messages
- Block CTCP anywhere in PRIVMSG and NOTICE, not just at first character
- Check for lower case commands
(Thanks sponge!)
2007-10-07 jrandom

* i2psnark: Fix outbound tunnel nickname
2007-08-05 Complication
* Update the sharing calculator on config.jsp
and explain the trade-off even more thoroughly.
2007-08-04 Complication
* Lower the threshold between the K and L bandwidth class,
so that K is now < 12 KB/s, instead of <= 16 KB/s.
Hopefully this lets people with 128 kbit/s (16 KB/s) upload lines
participate in routing, if they keep the default share percentage.
2007-07-16 zzz
* i2psnark: Add tooltip info for choked/uninterested
2007-07-16 zzz

remove most of the default graphs to save some memory
2007-07-15 zzz
* Add current values to graph legends
* Fix up previous Rate fix to check for divide by zero
2007-07-14 Complication
* Take the post-download routerInfo size check back out of ReseedHandler,
since it wasn't helpful, and a lower limit caused false warnings.
* Give EepGet ability to enforce a min/max HTTP response size.
* Enforce a maximum response size of 8 MB when ReseedHandler
downloads into a ByteArrayOutputStream.
* Refactor ReseedHandler/ReseedRunner from static to ordinary classes,
change invocation from RouterConsoleRunner accordingly.
* Add an EepGet status listener to ReseedHandler to log causes of reseed failure,
provide status reports to indicate the progress of reseeding.
* Enable icon for default eepsite, and the index page
of the router console (more later).
2007-07-14 zzz
* Clean up graphs.jsp - set K=1024 where appropriate,
output image sizes in html, catch ooms, other minor tweaks
* Fix current event count truncation which fixes graphs with low
60-sec event counts displaying high values
(bw.* and router.* graphs for example were 1.5x too high)
Affects all "events per period" (non-lifetime) counts.
2007-07-09 zzz
* i2psnark: give a better error message for a non-i2p torrent
2007-07-07 zzz
* 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.
2007-07-04 zzz
* Display calculated share bandwidth and remove load testing
on config.jsp
2007-07-01 zzz
* Replace broken option i2np.udp.alwaysPreferred with
i2np.udp.preferred and adjust UDP bids; possible settings are
"false" (default), "true", and "always".
Default setting results in same behavior as before
(NTCP is preferred unless it isn't established and UDP is established).
Use to compare NTCP and UDP transports.
2007-06-27 jrandom
* fix for a streaming lib bug that could leave a thread waiting
indefinitely (thanks Complication!)
2007-06-16 Complication
* 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.
2007-05-06 Complication

which became deprecated with the old Syndie (thanks for alerting, itsu!)
2007-03-31 zzz
* Add trevorreznik jump server to the http proxy error page
* Add anonymity to the trackers supporting details links in i2psnark
2007-03-24 zzz

(thanks Takk and postman!)
2007-02-13 jrandom
* Tell our peers about who we know in the floodfill netDb every
6 hours or so, mitigating the situation where peers lose track
of floodfill routers.
* Disable the Syndie updater (people should use the new Syndie,
not this one)
* Disable the eepsite tunnel by default
2007-01-30 zzz
* i2psnark: Don't hold _snarks lock while checking a snark,
so web page is responsive at startup
2007-01-28 zzz
* i2psnark: Don't hold sendQueue lock while flushing output,
to make everything run smoother
2007-01-27 zzz
* i2psnark: Fix orphaned Snark reader tasks leading to OOMs
2007-01-20 Complication
* Drop overlooked comment
2007-01-20 Complication
* 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.
2007-01-20 zzz
* i2psnark: More choking rotation tweaks
* Improve performance by not reading in the whole
piece from disk for each request. A huge memory savings
on 1MB torrents with many peers.

* Don't start tunnel if 'Autostart' unchecked
* Fix torrent restart bug by reopening file descriptors
2007-01-14 zzz

choke based on upload rate when seeding, and
be smarter and fairer about rotating choked peers.
* Handle two common i2psnark OOM situations rather
than shutting down the whole thing.
* Fix reporting to tracker of remaining bytes for
torrents > 4GB (but ByteMonsoon still has a bug)
2006-10-29 zzz
* i2psnark: Fix and enable generation of multifile torrents,
print error if no tracker selected at create-torrent,
fix stopping a torrent that hasn't started successfully,
add eBook and GayTorrents trackers to form,
web page formatting tweaks
2006-10-29 Complication
* Ensure we get NTP samples from more diverse sources
(0.pool.ntp.org, 1.pool.ntp.org, etc)
* Discard median-based peer skew calculator as framed average works,
and adjusting its percentage can make it behave median-like
* Require more data points (from at least 20 peers)
before considering a peer skew measurement reliable
2006-10-10 jrandom
* Removed the status display from the console, as its more confusing
than informative (though the content is still displayed in the HTML)
2006-10-08 Complication
* Add a framed average peer clock skew calculator
* Add config property "router.clockOffsetSanityCheck" to determine
if NTP-suggested clock offsets get sanity checked (default "true")
* Reject NTP-suggested clock offsets if they'd increase peer clock skew
by more than 5 seconds, or make it more than 20 seconds total
* Decrease log level in getMedianPeerClockSkew()
2006-09-29 zzz
* i2psnark: Second try at synchronization fix - synch addRequest()
completely rather than just portions of it and requestNextPiece()
2006-09-27 jrandom
* added HMAC-SHA256
* properly use CRLF with EepPost
* suppress jbigi/jcpuid messages if jbigi.dontLog/jcpuid.dontLog is set
* PBE session key generation (with 1000 rounds of SHA256)
* misc SDK helper functions
2006-09-26 Complication
* Take back another inadverent logging change in NTCPConnection
2006-09-26 Complication
* Take back an accidental log level change
2006-09-26 Complication
* Subclass from Clock a RouterClock which can access router transports,
with the goal of developing it to second-guess NTP results
* Make transports report clock skew in seconds
* Adjust renderStatusHTML() methods accordingly
* Show average for NTCP clock skews too
* Give transports a getClockSkews() method to report clock skews
* Give transport manager a getClockSkews() method to aggregate results
* Give comm system facade a getMedianPeerClockSkew() method which RouterClock calls
(to observe results, add "net.i2p.router.transport.CommSystemFacadeImpl=WARN" to logging)
* Extra explicitness in NTCP classes to denote unit of time.
* Fix some places in NTCPConnection where milliseconds and seconds were confused
2006-09-25 zzz
* i2psnark: Paranoid copy before writing pieces,
recheck files on completion, redownload bad pieces
* i2psnark: Don't contact tracker as often when seeding
2006-09-24 zzz
* i2psnark: Add some synchronization to prevent rare problem
after restoring orphan piece
2006-09-20 zzz
* i2psnark: Eliminate duplicate requests caused by i2p-bt's
rapid choke/unchokes
* i2psnark: Truncate long TrackerErr messages on web page
2006-09-16 zzz
* 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.
2006-09-13 zzz
* i2psnark: Fix restoral of partial pieces broken by last patch
* 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
2006-09-09 zzz
* i2psnark: Add "Stalled" indication and stat totals on web page
2006-09-09 zzz
* i2psnark: Fix bug where new peers would always be sent an "interested"
regardless of actual interest
* i2psnark: Reduce max piece size from 10MB to 1MB; larger may have severe
memory and efficiency problems
2006-09-08 jrandom
* Tweak the PRNG logging so it only displays error messages if there are
problems
* Disable dynamic router keys for the time being, as they don't offer
meaningful security, may hurt the router, and makes it harder to
determine the network health. The code to restart on SSU IP change is
still enabled however.
* Disable tunnel load testing, leaning back on the tiered selection for
the time being.
* Spattering of bugfixes
2006-09-07 zzz
* i2psnark: Increase output timeout from 2 min to 4 min
* i2psnark: Orphan debug msg cleanup
* i2psnark: More web rate report cleanup
2006-09-05 zzz
* 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
2006-09-04 zzz

* i2psnark: Don't delay tracker fetch when setting up lots of connections
* i2psnark: Reduce MAX_UPLOADERS from 12 to 4
2006-09-04 zzz

the scaling on their processing
2006-07-31 jrandom
* Increase the tunnel building timeout
* Avoid a rare race (thanks bar!)
* Fix the bandwidth capacity publishing code to factor in share percentage
and outbound throttling (oops)
2006-07-29 Complication
* Treat NTP responses from unexpected stratums like failures
2006-07-28 jrandom
* Don't try to reverify too many netDb entries at once (thanks
cervantes and Complication!)
2006-07-28 jrandom
* Actually fix the threading deadlock issue in the netDb (removing
the synchronized access to individual kbuckets while validating
individual entries) (thanks cervantes, postman, frosk, et al!)
2006-07-27 jrandom
* Cut down NTCP connection establishments once we know the peer is skewed
(rather than wait for full establishment before verifying)
* Removed a lock on the stats framework when accessing rates, which
shouldn't be a problem, assuming rates are created (pretty much) all at
once and merely updated during the lifetime of the jvm.
2006-07-27 jrandom
* Further NTCP write status cleanup
* Handle more oddly-timed NTCP disconnections (thanks bar!)
2006-07-26 jrandom
* When dropping a netDb router reference, only accept newer
references as part of the update check
* If we have been up for a while, don't accept really old
router references (published 2 or more days ago)
* Drop router references once they are no longer valid, even if
they were allowed in due to the lax restrictions on startup
2006-07-26 jrandom
* Every time we create a new router identity, add an entry to the
new "identlog.txt" text file in the I2P install directory. For
debugging purposes, publish the count of how many identities the
router has cycled through, though not the identities itself.
* Cleaned up the way the multitransport shitlisting worked, and
added per-transport shitlists
* When dropping a router reference locally, first fire a netDb
lookup for the entry
* Take the peer selection filters into account when organizing the
profiles (thanks Complication!)
* Avoid some obvious configuration errors for the NTCP transport
(invalid ports, "null" ip, etc)
* Deal with some small NTCP bugs found in the wild (unresolveable
hosts, strange network discons, etc)
* Send our netDb info to peers we have direct NTCP connections to
after each 6-12 hours of connection uptime
* Clean up the NTCP reading and writing queue logic to avoid some
potential delays
* Allow people to specify the IP that the SSU transport binds on
locally, via the advanced config "i2np.udp.bindInterface=1.2.3.4"
* 2006-07-18 0.6.1.22 released
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!)
2006-07-16 Complication
* Collect tunnel build agree/reject/expire statistics
for each bandwidth tier of peers (and peers of unknown tiers,
even if those shouldn't exist)
2006-07-14 jrandom
* 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
2006-07-04 jrandom
* 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
2006-07-01 Complication
* 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!)
2006-06-14 cervantes
* Small tweak to I2PTunnel CSS, so it looks better with desktops
that use Bitstream Vera fonts @ 96 dpi
2006-06-13 jrandom
* Use a minimum uptime of 2 hours, not 4 (oops)
2006-06-13 jrandom
* Cut down the proactive rejections due to queue size - if we are
at the point of having decrypted the request off the queue, might
as well let it through, rather than waste that decryption
2006-06-11 Kloug
* Bugfix to the I2PTunnel IRC filter to support multiple concurrent
outstanding pings/pongs
2006-06-10 jrandom
* Further reduction in proactive rejections
2006-06-09 jrandom
* Don't let the pending tunnel request queue grow beyond reason
(letting things sit for up to 30s when they fail after 10s
seems a bit... off)

* Be more conservative in the proactive rejections
2006-06-04 Complication
* Trim out sending a blank line before USER in susimail.
Seemed to break in rare cases, thanks for reporting, Brachtus!
* 2006-06-04 0.6.1.20 released
2006-06-04 jrandom
* Reduce the SSU ack frequency
* Tweaked the tunnel rejection settings to reject less aggressively
2006-05-31 jrandom
* Only send netDb searches to the floodfill peers for the time being
* Add some proof of concept filters for tunnel participation. By default,
it will skip peers with an advertised bandwith of less than 32KBps or
an advertised uptime of less than 2 hours. If this is sufficient, a
safer implementation of these filters will be implemented.
* 2006-05-18 0.6.1.19 released
2006-05-18 jrandom
* Made the SSU ACKs less frequent when possible
2006-05-17 Complication
* Fix some oversights in my previous changes:
adjust some loglevels, make a few statements less wasteful,
make one comparison less confusing and more likely to log unexpected values
2006-05-17 jrandom
* Make the peer page sortable
* SSU modifications to cut down on unnecessary connection failures
2006-05-16 jrandom
* Further shitlist randomizations
* Adjust the stats monitored for detecting cpu overload when dropping new
tunnel requests
2006-05-15 jrandom
* Add a load dependent throttle on the pending inbound tunnel request
backlog
* Increased the tunnel test failure slack before killing a tunnel
2006-05-13 Complication
* Separate growth factors for tunnel count and tunnel test time
* Reduce growth factors, so probabalistic throttle would activate
* Square probAccept values to decelerate stronger when far from average
* Create a bandwidth stat with approximately 15-second half life
* Make allowTunnel() check the 1-second bandwidth for overload
before doing allowance calculations using 15-second bandwidth
* Tweak the overload detector in BuildExecutor to be more sensitive
for rising edges, add ability to initiate tunnel drops
* Add a function to seek and drop the highest-rate participating tunnel,
keeping a fixed+random grace period between such drops.
It doesn't seem very effective, so disabled by default
("router.dropTunnelsOnOverload=true" to enable)
2006-05-11 jrandom
* PRNG bugfix (thanks cervantes and Complication!)
* 2006-05-09 0.6.1.18 released
2006-05-09 jrandom
* Further tunnel creation timeout revamp
2006-05-07 Complication
* Fix problem whereby repeated calls to allowed() would make
the 1-tunnel exception permit more than one concurrent build
2006-05-06 jrandom
* Readjust the tunnel creation timeouts to reject less but fail earlier,
while tracking the extended timeout events.
2006-05-04 jrandom
* Short circuit a highly congested part of the stat logging unless its
required (may or may not help with a synchronization issue reported by
andreas)
2006-05-03 Complication
* Allow a single build attempt to proceed despite 1-minute overload
only if the 1-second rate shows enough spare bandwidth
(e.g. overload has already eased)
2006-05-02 Complication
* 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
2006-05-01 jrandom
* Adjust the tunnel build timeouts to cut down on expirations, and
increased the SSU connection establishment retransmission rate to
something less glacial.
* For the first 5 minutes of uptime, be less aggressive with tunnel
exploration, opting for more reliable peers to start with.
2006-05-01 jrandom
* Fix for a netDb lookup race (thanks cervantes!)
2006-04-27 jrandom
* Avoid a race in the message reply registry (thanks cervantes!)
2006-04-27 jrandom
* Fixed the tunnel expiration desync code (thanks Complication!)
2006-04-19 jrandom
* 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
2006-04-15 jrandom
* Adjust the proactive tunnel request dropping so we will reject what we
can instead of dropping so much (but still dropping if we get too far
overloaded)
2006-04-14 jrandom
* 0 isn't very random
* Adjust the tunnel drop to be more reasonable
2006-04-14 jrandom
* -28.00230115311259 is not between 0 and 1 in any universe I know.
* Made the bw-related tunnel join throttle much simpler
2006-04-14 jrandom
* Make some more stats graphable, and allow some internal tweaking on the
tunnel pairing for creation and testing.
2006-04-12 jrandom
* Added a further failsafe against trying to queue up too many messages to
a peer.
2006-04-12 jrandom
* Watch out for failed syndie index fetches (thanks bar!)
2006-04-11 jrandom
* Throttling improvements on SSU - throttle all transmissions to a peer
when we are retransmitting, not just retransmissions. Also, if
we're already retransmitting to a peer, probabalistically tail drop new
messages targetting that peer, based on the estimated wait time before
transmission.
* Fixed the rounding error in the inbound tunnel drop probability.
2006-04-10 jrandom
* 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.
2006-04-08 jrandom
* Stat summarization fix (removing the occational holes in the jrobin
graphs)
2006-04-08 jrandom
* 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
2006-04-06 jrandom
* Fix for a bug in the new irc ping/pong filter (thanks Complication!)
2006-04-06 jrandom
* Fixed a typo in the reply cleanup code
2006-04-05 jrandom
* 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
2006-04-05 jrandom
* 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!)
2006-04-01 jrandom
* 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!)
2006-03-30 jrandom
* Substantially reduced the lock contention in the message registry (a
major hotspot that can choke most threads). Also reworked the locking
so we don't need per-message timer events
* No need to have additional per-peer message clearing, as they are
either unregistered individually or expired.
* Include some of the more transient tunnel throttling
2006-03-25 jrandom
* 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
2006-03-24 jrandom
* Try to desync tunnel building near startup (thanks Complication!)
* If we are highly congested, fall back on only querying the floodfill
netDb peers, and only storing to those peers too
* Cleaned up the floodfill-only queries
2006-03-21 jrandom
* 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)
2006-03-20 jrandom
* Fix to allow for some slack when coalescing stats
* Workaround some oddball errors
2006-03-18 jrandom
* Added a new graphs.jsp page to show all of the stats being harvested
2006-03-18 jrandom
* 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
2006-03-17 jrandom
* 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
