* 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.
* I2PTunnel bugfix (thanks Complication!)
* Increase the SSU cwin slower during congestion avoidance (at k/cwin^2
instead of k/cwin)
* Limit the number of inbound SSU sessions being built at once (using
half of the i2np.udp.maxConcurrentEstablish config prop)
* Don't shitlist on a message send failure alone (unless there aren't any
common transports).
* More careful bandwidth bursting
* Better i2paddresshelper handling in the I2PTunnel httpclient, plus a new
conflict resolution page if the i2paddresshelper parameter differs from
an existing name to destination mapping.

* Fix a long standing streaming lib bug (in the inactivity detection code)
* Improved handling of initial streaming lib packet retransmissions to
kill the "lost first packet" bug (where a page shows up with the first
few KB missing)
* Add support for initial window sizes greater than 1 - useful for
eepsites to transmit e.g. 4 packets full of data along with the initial
ACK, thereby cutting down on the rtt latency. The congestion window
size can and does still shrink down to 1 packet though.
* Adjusted the streaming lib retransmission calculation algorithm to be
more TCP-like.
* Bugfix in susidns for deleting entries
2005-09-21 jrandom
* Add support for HTTP POST to EepGet
* Use HTTP POST for syndie bulk fetches, since there's a lot of data to
put in that URL.
* Added support for pure 64bit linux with jbigi and the java service
wrapper (no need for jcpuid if we're on os.arch=amd64). Thanks mule
et al for help testing!
* UI cleanup in Syndie (thanks gloin and bar!)
2005-09-17 jrandom
* Clean up syndie a bit more and bundle a default introductory post with
both new installs and updates.
* Typo fixes on the console (thanks bar!)
* Removed guaranteed delivery mode entirely (so existing i2phex clients
using it can get the benefits of mode=best_effort). Guaranteed delivery
is offered at the streaming lib level.
* Improve the peer selection code for peer testing, as everyone now
supports tests.
* Give the watchdog its fangs - if it detects obscene job lag or if
clients have been unable to get a leaseSet for more than 5 minutes,
restart the router. This was disabled a year ago due to spurious
restarts, and can be disabled by "watchdog.haltOnHang=false", but the
cause of the spurious restarts should be gone.
* 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
* Catch errors with corrupt tunnel messages more gracefully (no need to
kill the thread and cause an OOM...)
* Don't skip shitlisted peers for netDb store messages, as they aren't
necessarily shitlisted by other people (though they probably are).
* Adjust the netDb store per-peer timeout based on each particular peer's
profile (timeout = 4x their average netDb store response time)
* Don't republish leaseSets to *failed* peers - send them to peers who
replied but just didn't know the value.
* Set a 5 second timeout on the I2PTunnelHTTPServer reading the client's
HTTP headers, rather than blocking indefinitely. HTTP headers should be
sent entirely within the first streaming packet anyway, so this won't be
a problem.
* Don't use the I2PTunnel*Server handler thread pool by default, as it may
prevent any clients from accessing the server if the handlers get
blocked by the streaming lib or other issues.
* Don't overwrite a known status (OK/ERR-Reject/ERR-SymmetricNAT) with
Unknown.
* Removed the concept of "no bandwidth limit" - if none is specified, its
16KBps in/out.
* Include ack packets in the per-peer cwin throttle (they were part of the
bandwidth limit though).
* Tweak the SSU cwin operation to get more accurrate estimates under
congestions.
* SSU improvements to resend more efficiently.
* Added a basic scheduler to eepget to fetch multiple files sequentially.
* Revise the SSU peer testing protocol so that Bob verifies Charlie's
viability before agreeing to Alice's request. This doesn't work with
older SSU peer test builds, but is backwards compatible (older nodes
won't ask newer nodes to participate in tests, and newer nodes won't
ask older nodes to either).
* Add a configurable throttle to the number of concurrent outbound SSU
connection negotiations (via i2np.udp.maxConcurrentEstablish=4). This
may help those with slow connections to get integrated at the start.
* Further fixlets to the streaming lib
2005-07-27 jrandom
* Enabled SSU as the default top priority transport, adjusting the
config.jsp page accordingly.
* Add verification fields to the SSU and TCP connection negotiation (not
compatible with previous builds)
* Enable the backwards incompatible tunnel crypto change as documented in
tunnel-alt.html (have each hop encrypt the received IV before using it,
then encrypt it again before sending it on)
* Disable the I2CP encryption, leaving in place the end to end garlic
encryption (another backwards incompatible change)
* Adjust the protocol versions on the TCP and SSU transports so that they
won't talk to older routers.
* Fix up the config stats handling again
* Fix a rare off-by-one in the SSU fragmentation
* Reduce some unnecessary netDb resending by inluding the peers queried
successfully in the store redundancy count.
* Fix in the SDK for a bug which would manifest itself as misrouted
streaming packets when a destination has many concurrent streaming
connections (thanks duck!)
* No more "Graceful shutdown in -18140121441141s"
* Further preparation for removing I2CP crypto
* Added some validation to the DH key agreement (thanks $anon)
* Validate tunnel data message expirations (though not really a problem,
since tunnels expire)
* Minor PRNG threading cleanup
* Fixed a long standing bug where we weren't properly comparing session
tags but instead largely depending upon comparing their hashCode,
causing intermittent decryption errors.
* Reduced the growth factor on the slow start and congestion avoidance for
the streaming lib.
* Adjusted some of the I2PTunnelServer threading to use a small pool of
handlers, rather than launching off new threads which then immediately
launch off an I2PTunnelRunner instance (which launches 3 more threads..)
* Don't persist session keys / session tags (not worth it, for now)
* Added some detection and handling code for duplicate session tags being
delivered (root cause still not addressed)
* Make the PRNG's buffer size configurable (via the config property
"i2p.prng.totalBufferSizeKB=4096")
* Disable SSU flooding by default (duh)
* Updates to the StreamSink apps for better throttling tests.
* Use a buffered PRNG, pulling the PRNG data off a larger precalculated
buffer, rather than the underlying PRNG's (likely small) one, which in
turn reduces the frequency of recalcing.
* More tuning to reduce temporary allocation churn
* Within the tunnel, use xor(IV, msg[0:16]) as the flag to detect dups,
rather than the IV by itself, preventing an attack that would let
colluding internal adversaries tag a message to determine that they are
in the same tunnel. Thanks dvorak for the catch!
* Drop long inactive profiles on startup and shutdown
* /configstats.jsp: web interface to pick what stats to log
* Deliver more session tags to account for wider window sizes
* Cache some intermediate values in our HMACSHA256 and BC's HMAC
* Track the client send rate (stream.sendBps and client.sendBpsRaw)
* UrlLauncher: adjust the browser selection order
* I2PAppContext: hooks for dummy HMACSHA256 and a weak PRNG
* StreamSinkClient: add support for sending an unlimited amount of data
* Migrate the tests out of the default build jars
2005-06-22 Comwiz
* Migrate the core tests to junit
* Phase 1 of the unit test bounty completed. (The router build script was modified not to build the router
tests because of a broken dependancy on the core tests. This should be fixed in
phase 3 of the unit test bounty.)
