* 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
* 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.
* 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)
* 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.

* 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
* 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!)
* 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)
(enjoy, duck)
packets through that point have been ACKed, throwing an
InterruptedIOException if there was a writeTimeout or an IOException
if the con failed
* revamped the ack/nack field settings to ack as much as possible
* handle some strange timeout/resend errors on connection
* pass 1/2rtt as the packet 'optional delay' field, and use that to
schedule the ack time (the 'last' messages in a window set the
optional delay to 0, asking for immediate ack of all received)
* increase the optional delay to 2 bytes (#ms to delay)
* inject random failures and delays if configured to do so in
PacketHandler.choke
* fix up the window size adjustment (increment on ack, /= 2 on resend)
* use the highest RTT in the new RTT calculation so that we fit more
in (via SACK)
* fix up the SACK handling (duh)
* revise the resend time calculation
* properly close the source file in StreamSinkSend
* always adjust the rtt on ack, not just for packets with 1 send
* handle dup SYN gracefully
* revamp the default connection options
* logging
* immediately send an ack on receiving a duplicate payload message
(unless we've sent one within the last RTT)
* only adjust the RTT when there have been no resends
* added some (disabled) throttles - randomly injecting delays on
received packets, as well as randomly dropping them
* logging
has session tags within it, send an additional ping to the peer,
bundling those tags a second time, ACKing those tags on the pong.
* handle packets transferred during a race after the receiver ACKs the
connection but before the establisher receives the ACK.
* notify the messageInputStream reader on close (duh)
* new stream sink test, shoving lots and lots of data down a stream
with the existing StreamSinkServer and StreamSinkClient apps
* logging
* 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 implementation to instantiate.
* Enable explicit disabling of the systray entirely for windows machines
with strange configurations: add -Dsystray.disable=true to the java
command line. (thanks mihi!)
* 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!)

* 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)
* 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.
plus minor bugfixes / refactoring / logging
- sendsPerFailure: how many partial sends we make when they all fail
- timeoutCongestionInbound: describes how much faster than our average speed we were receiving data when each partial send timed out (in Bps)
- timeoutCongestionMessage: our send processing time when each partial send timed out (in ms)
- timeoutCongestionTunnel: our tunnel test time when each partial send timed out (in ms)
- participatingMessagesProcessedActive: # of messages more than the (most recent) average that a tunnel we were participating in transmitted (for tunnels with more than the average)
* updated to use Writer for rendering the console, so we can do partial writes (and hopefully help debug some kooky threading bugs on kaffe)
* Always wipe the Jetty work directory on startup, so that web updates
are reflected immediately (Jetty does not honor the cache across
multiple executions)
in addition, refactor various file ops out of the DataHelper into FileUtil
* 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.
* 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 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
* 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
* 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.
* Handle a bug in the SimpleTimer with requeued tasks.
* 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.
* 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
* 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.
* 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
