* (Merged the 0.5-pre branch back into CVS HEAD)
* Replaced the old tunnel routing crypto with the one specified in
router/doc/tunnel-alt.html, including updates to the web console to view
and tweak it.
* Provide the means for routers to reject tunnel requests with a wider
range of responses:
probabalistic rejection, due to approaching overload
transient rejection, due to temporary overload
bandwidth rejection, due to persistent bandwidth overload
critical rejection, due to general router fault (or imminent shutdown)
The different responses are factored into the profiles accordingly.
* Replaced the old I2CP tunnel related options (tunnels.depthInbound, etc)
with a series of new properties, relevent to the new tunnel routing code:
inbound.nickname (used on the console)
inbound.quantity (# of tunnels to use in any leaseSets)
inbound.backupQuantity (# of tunnels to keep in the ready)
inbound.length (# of remote peers in the tunnel)
inbound.lengthVariance (if > 0, permute the length by adding a random #
up to the variance. if < 0, permute the length
by adding or subtracting a random # up to the
variance)
outbound.* (same as the inbound, except for the, uh, outbound tunnels
in that client's pool)
There are other options, and more will be added later, but the above are
the most relevent ones.
* Replaced Jetty 4.2.21 with Jetty 5.1.2
* Compress all profile data on disk.
* Adjust the reseeding functionality to work even when the JVM's http proxy
is set.
* Enable a poor-man's interactive-flow in the streaming lib by choking the
max window size.
* Reduced the default streaming lib max message size to 16KB (though still
configurable by the user), also doubling the default maximum window
size.
* Replaced the RouterIdentity in a Lease with its SHA256 hash.
* Reduced the overall I2NP message checksum from a full 32 byte SHA256 to
the first byte of the SHA256.
* Added a new "netId" flag to let routers drop references to other routers
who we won't be able to talk to.
* Extended the timestamper to get a second (or third) opinion whenever it
wants to actually adjust the clock offset.
* Replaced that kludge of a timestamp I2NP message with a full blown
DateMessage.
* Substantial memory optimizations within the router and the SDK to reduce
GC churn. Client apps and the streaming libs have not been tuned,
however.
* More bugfixes thank you can shake a stick at.

* Updated jbigi source to handle 64bit CPUs. The bundled jbigi.jar still
only contains 32bit versions, so build your own, placing libjbigi.so in
your install dir if necessary. (thanks mule!)
* Added support for libjbigi-$os-athlon64 to NativeBigInteger and CPUID
(thanks spaetz!)
* 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
* 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
got some pretty heavy GC churn when under load. rough estimate is we allocate 5-8x as
much data as we need, copying it all over the place before forwarding it (or processing it).
this should cut down a few of those copies, but not enough yet. it'd be great to get that
down to 2x.
* lots of logging
a rooted app context. The core itself has its own I2PAppContext
(see its javadoc for, uh, docs), and the router extends that to
expose the router's singletons. The main point of this is to
make it so that we can run multiple routers in the same JVM, even
to allow different apps in the same JVM to switch singleton
implementations (e.g. run some routers with one set of profile
calculators, and other routers with a different one).
There is still some work to be done regarding the actual boot up
of multiple routers in a JVM, as well as their configuration,
though the plan is to have the RouterContext override the
I2PAppContext's getProperty/getPropertyNames methods to read from
a config file (seperate ones per context) instead of using the
System.getProperty that the base I2PAppContext uses.
Once the multi-router is working, i'll shim in a VMCommSystem
that doesn't depend upon sockets or threads to read/write (and
that uses configurable message send delays / disconnects / etc,
perhaps using data from the routerContext.getProperty to drive it).
I could hold off until the sim is all working, but there's a
truckload of changes in here and I hate dealing with conflicts ;)
Everything works - I've been running 'er for a while and kicked
the tires a bit, but if you see something amiss, please let me
know.
