- Enable IPv6 stack in the JVM, hopefully won't break anything
- Patch Jetty to support binding to IPv6 addresses
- Allow multiple bind addresses for the router console
in the clients.config file; for new installs the
default is now "127.0.0.1,::1"
- Change most instances of "localhost" to "127.0.0.1"
throughout the code
* Router:
- Move some classes to private static inner
- Use the depend task with caching for more accurate dependencies
- Make sure the routerconsole gets the latest router version
- Fix addressbook repeated builds
Added socketSoTimeout
CHANGED RetransmissionTimer is now public
FIXED SimpleTimer has a way to be stopped, and reap it's children
CLEANUP A few javadoc additions, where I could figgure out bits
CLEANUP all code that needed to catch the timeout exception for socketSoTimeout
Added socketSoTimeout
CHANGED RetransmissionTimer is now public
FIXED SimpleTimer has a way to be stopped, and reap it's children
FIXED Lots of javadoc additions, where I could
CLEANUP all code that needed to catch the timeout exception for socketSoTimeout
and fixed all the broken mainstream applications depending on it.
Fixed a grave bug in SimpleTimer.
Fixed Steraming Timer to be public.
Fixed a pile of JavaDoc comments, and reformatted the files I touched.
* eepsite_index.html: Add links to trevorreznik address book
* streaming lib: Fix SocketManagerFactory to honor options on outbound connections
* streaming lib: Fix setDefaultOptions() when called with a ConnectionOptions parameter
* i2psnark: Don't make outbound connections to already-connected peers
* i2psnark: Debug logging cleanup
* 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.
* 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
* In the SDK, we don't actually need to block when we're sending a message
as BestEffort (and these days, we're always sending BestEffort).
* Pass out client messages in fewer (larger) steps.
* Have the InNetMessagePool short circuit dispatch requests.
* Have the message validator take into account expiration to cut down on
false positives at high transfer rates.
* Allow configuration of the probabalistic window size growth rate in the
streaming lib's slow start and congestion avoidance phases, and default
them to a more conservative value (2), rather than the previous value
(1).
* Reduce the ack delay in the streaming lib to 500ms
* Honor choke requests in the streaming lib (only affects those getting
insanely high transfer rates)
* Let the user specify an interface besides 127.0.0.1 or 0.0.0.0 on the
I2PTunnel client page (thanks maestro^!)
(plus minor udp tweaks)
* Update the old speed calculator and associated profile data points to
use a non-tiered moving average of the tunnel test time, avoiding the
freshness issues of the old tiered speed stats.
* Explicitly synchronize all of the methods on the PRNG, rather than just
the feeder methods (sun and kaffe only need the feeder, but it seems ibm
needs all of them synchronized).
* Properly use the tunnel tests as part of the profile stats.
* Don't flood the jobqueue with sequential persist profile tasks, but
instead, inject a brief scheduling delay between them.
* Reduce the TCP connection establishment timeout to 20s (which is still
absurdly excessive)
* Reduced the max resend delay to 30s so we can get some resends in when
dealing with client apps that hang up early (e.g. wget)
* Added more alternative socketManager factories (good call aum!)
* Adjust the old speed calculator to include end to end RTT data in its
estimates, and use that as the primary speed calculator again.
* Use the mean of the high capacity speeds to determine the fast
threshold, rather than the median. Perhaps we should use the mean of
all active non-failing peers?
* Updated the profile page to sort by tier, then alphabetically.
* Added some alternative socketManager factories (good call aum!)
* Really disable the streaming lib packet caching
* Synchronized a message handling point in the SDK (even though its use is
already essentially single threaded, its better to play it safe)
* Don't add new RepublishLeaseSetJobs on failure, just requeue up the
existing one (duh)
* Throttle the number of concurrent pending tunnel builds across all
pools, in addition to simply throttling the number of new requests per
minute for each pool individually. This should avoid the cascading
failure when tunnel builds take too long, as no new builds will be
created until the previous ones are handled.
* Factored out and extended the DataHelper's unit tests for dealing with
long and date formatting.
* Explicitly specify the HTTP auth realm as "i2prouter", though this
alone doesn't address the bug where jetty asks for authentication too
much. (thanks orion!)
* Updated the StreamSinkServer to ignore all read bytes, rather than write
them to the filesystem.
* (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.
2005-02-13 jrandom
* 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!)
* Added meaningful support for adjusting the preferred message size in the
streaming lib by setting the i2p.streaming.maxMessageSize=32768 (or
whatever). The other side will mimic a reduction (but never an increase).
* Always make sure to use distinct ConnectionOption objects for each
connection (duh)
* Reduced the default ACK delay to 500ms on in the streaming lib
* Only shrink the streaming window once per window
* Don't bundle a new jetty.xml with updates
* Catch another local routerInfo corruption issue on startup.
* Handle unexpected network read errors more carefully (thanks parg!)
* Added more methods to partially compare (DataHelper) and display
arrays (Base64.encode).
* Exposed the AES encryptBlock/decryptBlock on the context.aes()
* Be more generous on the throttle when just starting up the router
* Fix a missing scheduled event in the streaming lib (caused after reset)
* Add a new DisconnectListener on the I2PSocketManager to allow
notification of session destruction.
* Make sure our own router identity is valid, and if it isn't, build a new
one and restart the router. Alternately, you can run the Router with
the single command line argument "rebuild" and it will do the same.
* Use a simpler and less memory intensive job for processing outbound
client messages when the session is in mode=bestEffort. We can
immediately discard the data as soon as its sent the first time,
rather than wait for an ack, since we will never internally resend.
* Reduce some synchronization to avoid a rare deadlock
* Replaced 'localhost' with 127.0.0.1 in the i2ptunnel config, and special
case it within the tunnel controller.
* Script cleanup for building jbigi/jcpuid
* Logging
* Toss in a small pool of threads (3) to execute the events queued up with
the SimpleTimer, as we do currently see the occational event
notification spiking up to a second or so.
* Implement a SAM client API in java, useful for event based streaming (or
for testing the SAM bridge)
* Added support to shut down the SAM bridge on OOM (useful if the SAM
bridge is being run outside of the router).
* Include the SAM test code in the sam.jar
* Remove an irrelevent warning message from SAM, which was caused by
perfectly normal operation due to a session being closed.
* Removed some unnecessary synchronization in the streaming lib's
PacketQueue
* More quickly clean up the memory used by the streaming lib by
immediately killing each packet's resend job as soon as it is ACKed (or
cancelled), so that there are no longer any valid pointers to the
(potentially 32KB) packet.
* Fixed the timestamps dumped to stdout when debugging the PacketHandler.
* Drop packets that would expand our inbound window beyond our maximum
buffer size (default 32 messages)
* Always read the ACK/NACK data from the verified packets received, even
if we are going to drop them
* Always adjust the window when there are messages ACKed, though do not
change its size except as before.
* Streamlined some synchronization in the router's I2CP handling
* Streamlined some memory allocation in the SAM bridge
* Default the streaming lib to disconnect on inactivity, rather than send
an empty message.
this still doesnt get the BT to where it needs to be, or fix the timeout problem,
but i dont like having so many commits outstanding and these updates are sound
* 2004-11-26 0.4.2 released
2004-11-26 jrandom
* Enable the new streaming lib as the default. That means, for any
substantial definition, it is NOT BACKWARDS COMPATIBLE.
* Revised the installer to include start menu and desktop shortcuts for
windows platforms, including pretty icons (thanks DrWoo!)
* Allow clients specified in clients.config to have an explicit startup
delay.
* Update the default install to launch a browser pointing at the console
whenever I2P starts up, rather than only the first time it starts up
(configurable on /configservice.jsp, or in clients.config)
* Bugfix to the clock skew checking code to monitor the delta between
offsets, not the offset itself (duh)
* Router console html update
* New (and uuuuugly) code to verify that the wrapper.config contains
the necessary classpath entries on update. If it has to update the
wrapper.config, it will stop the JVM and service completely, since the
java service wrapper doesn't reread the wrapper.config on JVM restart -
requiring the user to manually restart the service after an update.
* Increase the TCP connection timeout to 30s (which is obscenely long)
------------------------------------------------
* Remove spurious flush calls from I2PTunnel, and work with the
I2PSocket's output stream directly (as the various implementations
do their own buffering).
* Another pass at a long standing JobQueue bug - dramatically simplify
the job management synchronization since we dont need to deal with
high contention (unlike last year when we had dozens of queue runners
going at once).
* Logging
* 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)
2004-10-30 jrandom
* 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
* 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
* 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.
