* 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)
* Expire queued messages even when the writer is blocked.
* Reimplement most of the I2NP writing with less temporary memory
allocations (I2NP reading still gobbles memory).
* 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.
