- Deprecate unused stream methods and I2NPMessageReader since
all transports provide encapsulation.
- Don't throw IOE from byte array methods
- Use cached null cert in GarlicClove
- Add method to limit size of buffer to read
- Don't check checksum at input, in most cases
- Reuse checksum at output, for unomodified pass-through messages
(but recalculating it now and logging on a mismatch for testing)
- Fix DatabaseLookupMessage to internally store the don't include peers as
a List, not a Set, so it doesn't get reordered and break the checksum
- Log cleanup
* NTCP:
- Zero-copy and limit size when handing buffer to I2NP
- Log hex dump message on I2NPMessageException, like in SSU
- Don't close connection on I2NPMessageException
- Earlier detection and better logging of
truncated TunnelGatewayMessage and DatabaseStoreMessage
- Fix and enhance UnknownI2NPMessage implementation
- Don't deserialize or verify the checksum of the
embeddedI2NP message in the TunnelGatewayMessage
at the IBGW, just use UnknownI2NPMessage and pass it along,
except if zero hop; Still to do: similar thing at OBEP
- Round expiration times when converting to/from seconds for SSU
- Cleanups and javadoc
- Kill the global app context
- Recognize multi-router case
- Fix RandomIterator, YKGenerator, DHBuilder, NTCPConnection
hanging on to old context -
probably other offenders not yet found
- Fix DHBuilder thread not stopping
* 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"
* (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!)
* 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.
* Added a watchdog timer to do some baseline liveliness checking to help
debug some odd errors.
* Added a pair of summary stats for bandwidth usage, allowing easy export
with the other stats ("bw.sendBps" and "bw.receiveBps")
* Trimmed another memory allocation on message reception.
* Reimplement the I2NP reading with less temporary memory allocation.
There is still significant GC churn, especially under load, but this
should help.
* Catch some oddball errors in the transport (message timeout while
establishing).
* 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!)
* removed SourceRouteBlock & SourceRouteReplyMessage, as they're a redundant concept
that 1) takes up bandwidth 2) takes up CPU 3) smell funny.
now the TunnelCreateMessage includes a replyTag, replyKey, replyTunnel, and
replyGateway that they garlic encrypt their ACK/NACK through and with.
* tunnelCreateMessage doesn't need a seperate ACK - either we get a
TunnelCreateStatusMessage back or we don't.
* message structure mods for unique tunnel ID per hop (though currently all hops have
the same tunnel ID)
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.
