* 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.

* 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
* 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.
* 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.
* 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

* 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)
* 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
* 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
* 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
* 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!)
* Default the I2CP listener to localhost only, unless overridden by
i2cp.tcp.bindAllInterfaces=true (thanks dm!)
* More SAM fixes for things recently broken (whee)
* 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.
* 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.
this still doesnt get the BT to where it needs to be, or fix the timeout problem,
but i dont like having so many commits outstanding and these updates are sound
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 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.
* 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
* 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.
* 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.
* 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.
* 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.
* 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
* 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.
* 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)
------------------------------------------------
* 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
* 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.
* 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)
* 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.
* 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).
* 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!)
* 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
* 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
* 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
* 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!)
