* If i2np.udp.fixedPort=true, never change the externally published port,
even if we are autodetecting the IP address.
* 2005-07-27 0.6 released
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.
2005-07-22 jrandom
* Use the small thread pool for I2PTunnelHTTPServer (already used for
I2PTunnelServer)
* Minor memory churn reduction in I2CP
* Small stats update
2005-07-21 jrandom
* 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"
2005-07-20 jrandom
* Allow the user to specify an external port # for SSU even if the external
host isn't specified (thanks duck!)
2005-07-19 jrandom
* 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
* Added workaround for an odd win32 bug in the stats configuration console
page which meant only the first checkbox selection was saved.
* Added per group selection toggles in the stats configuration console
page.
2005-07-13 jrandom
* Fixed a recently injected bug in the multitransport bidding which had
allowed an essentially arbitrary choice of transports, rather than the
properly ordered choice.
2005-07-13 jrandom
* 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.
* Add some data duplication to avoid a recently injected concurrency
problem in the session tag manager (thanks redzara and romster).
2005-07-11 jrandom
* 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.
2005-07-05 jrandom
* 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
2005-07-04 jrandom
* 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
2005-05-01 jrandom
* Added a substantial optimization to the AES engine by caching the
prepared session keys (duh).
2005-05-01 jrandom
* Cleaned up the peers page a bit more.
2005-04-30 jrandom
* Added a small new page to the web console (/peers.jsp) which contains
the peer connection information. This will be cleaned up a lot more
before 0.6 is out, but its a start.
2005-04-30 jrandom
* Reduced some SimpleTimer churn
2005-04-29 jrandom
* Reduce the peer profile stat coallesce overhead by inlining it with the
reorganize.
* Limit each transport to at most one address (any transport that requires
multiple entry points can include those alternatives in the address).
2005-04-28 jrandom
* More fixes for the I2PTunnel "other" interface handling (thanks nelgin!)
* Add back the code to handle bids from multiple transports (though there
is still only one transport enabled by default)
* Adjust the router's queueing of outbound client messages when under
heavy load by running the preparatory job in the client's I2CP handler
thread, thereby blocking additional outbound messages when the router is
hosed.
* No need to validate or persist a netDb entry if we already have it
2005-04-25 smeghead
* Added button to router console for manual update checks.
* Fixed bug in configupdate.jsp that caused the proxy port to be updated
every time the form was submitted even if it hadn't changed.
2005-04-24 jrandom
* Added a pool of PRNGs using a different synchronization technique,
hopefully sufficient to work around IBM's PRNG bugs until we get our
own Fortuna.
* In the streaming lib, don't jack up the RTT on NACK, and have the window
size bound the not-yet-ready messages to the peer, not the unacked
message count (not sure yet whether this is worthwile).
* Many additions to the messageHistory log.
* Handle out of order tunnel fragment delivery (not an issue on the live
net with TCP, but critical with UDP).
2005-04-20 jrandom
* 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^!)
2005-04-17 sirup
* Added the possibility for i2ptunnel client and httpclient instances to
have their own i2p session (and hence, destination and tunnels). By
default, tunnels are shared, but that can be changed on the web
interface or with the sharedClient config option in i2ptunnel.config.
2005-04-17 jrandom
* Marked the net.i2p.i2ptunnel.TunnelManager as deprecated. Anyone use
this? If not, I want to drop it (lots of tiny details with lots of
duplicated semantics).
2005-04-17 zzz
* Added new user-editable eepproxy error page templates.
2005-04-17 jrandom
* Revamp the tunnel building throttles, fixing a situation where the
rebuild may not recover, and defaulting it to unthrottled (users with
slow CPUs may want to set "router.tunnel.shouldThrottle=true" in their
advanced router config)
2005-04-16 jrandom
* Migrated to Bouncycastle's SHA256 and HMAC implementations for efficiency
2005-04-12 jrandom
* Make sure we don't get cached updates (thanks smeghead!)
* Clear out the callback for the TestJob after it passes (only affects the
job timing accounting)
2005-04-08 smeghead
* Added NativeBigInteger benchmark to scripts/i2pbench.sh.
2005-04-08 smeghead
* Security improvements to TrustedUpdate: signing and verification of the
version string along with the data payload for signed update files
(consequently the positions of the DSA signature and version string fields
have been swapped in the spec for the update file's header); router will
no longer perform a trusted update if the signed update's version is lower
than or equal to the currently running router's version.
* Added two new CLI commands to TrustedUpdate: showversion, verifyupdate.
* Extended TrustedUpdate public API for use by third party applications.
2005-04-05 jrandom
* Retry I2PTunnel startup if we are unable to build a socketManager for a
client or httpclient tunnel.
* Add some basic sanity checking on the I2CP settings (thanks duck!)
2005-04-05 jrandom
* After a successfull netDb search for a leaseSet, republish it to all of
the peers we have tried so far who did not give us the key (up to 10),
rather than the old K closest (which may include peers who had given us
the key)
* Don't wait 5 minutes to publish a leaseSet (duh!), and rather than
republish it every 5 minutes, republish it every 3. In addition, always
republish as soon as the leaseSet changes (duh^2).
* Minor fix for oddball startup race (thanks travis_bickle!)
* Minor AES update to allow in-place decryption.
2005-04-03 jrandom
* EepGet fix for open-ended HTTP fetches (such as the news.xml
feeding the NewsFetcher)
2005-04-01 jrandom
* Allow editing I2PTunnel server instances with five digit ports
(thanks nickless_head!)
* More NewsFetcher debugging for reported weirdness
2005-04-01 jrandom
* Fix to check for missing news file (thanks smeghead!)
* Added destination display CLI:
java -cp lib/i2p.jar net.i2p.data.Destination privKeyFilename
* Added destination display to the web interface (thanks pnspns)
* Installed CIA backdoor

* 2005-03-29 0.5.0.5 released
2005-03-29 jrandom
* Decreased the initial RTT estimate to 10s to allow more retries.
* Increased the default netDb store replication factor from 2 to 6 to take
into consideration tunnel failures.
* Address some statistical anonymity attacks against the netDb that could
be mounted by an active internal adversary by only answering lookups for
leaseSets we received through an unsolicited store.
* Don't throttle lookup responses (we throttle enough elsewhere)
* Fix the NewsFetcher so that it doesn't incorrectly resume midway through
the file (thanks nickster!)
* Updated the I2PTunnel HTML (thanks postman!)
* Added support to the I2PTunnel pages for the URL parameter "passphrase",
which, if matched against the router.config "i2ptunnel.passphrase" value,
skips the nonce check. If the config prop doesn't exist or is blank, no
passphrase is accepted.
* Implemented HMAC-SHA256.
* Enable the tunnel batching with a 500ms delay by default
* Dropped compatability with 0.5.0.3 and earlier releases
2005-03-26 jrandom
* Added some error handling and fairly safe to cache data to the streaming
lib (good call Tom!)
2005-03-25 jrandom
* Fixed up building dependencies for the routerconsole on some more
aggressive compilers (thanks polecat!)
2005-03-23 jrandom
* Added more intelligent version checking in news.xml, in case we have a
version newer than the one specified.
2005-03-23 jrandom
* Added support for Transfer-Encoding: chunked to the EepGet, so that the
cvsweb.cgi doesn't puke on us.
2005-03-23 Connelly
* Fixed Bugzilla Bug #99 in the SAM Bridge, which caused pending
stream send data to not be sent if STREAM CLOSE is issued too fast.
2005-03-23 jrandom
* Implemented the news fetch / update policy code, as configurated on
/configupdate.jsp. Defaults are to grab the news every 24h (or if it
doesn't exist yet, on startup). No action is taken however, though if
the news.xml specifies that a new release is available, an option to
update will be shown on the router console.
* New initialNews.xml delivered with new installs, and moved news.xml out
of the i2pwww module and into the i2p module so that we can bundle it
within each update.

* New /configupdate.jsp page for controlling the update / notification
process, as well as various minor related updates. Note that not all
options are exposed yet, and the update detection code isn't in place
in this commit - it currently says there is always an update available.
* New EepGet component for reliable downloading, with a CLI exposed in
java -cp lib/i2p.jar net.i2p.util.EepGet url
* Added a default signing key to the TrustedUpdate component to be used
for verifying updates. This signing key can be authenticated via
gpg --verify i2p/core/java/src/net/i2p/crypto/TrustedUpdate.java
* New public domain SHA1 implementation for the DSA code so that we can
handle signing streams of arbitrary size without excess memory usage
(thanks P.Verdy!)
* Added some helpers to the TrustedUpdate to work off streams and to offer
a minimal CLI:
TrustedUpdate keygen pubKeyFile privKeyFile
TrustedUpdate sign origFile signedFile privKeyFile
TrustedUpdate verify signedFile
2005-03-22 smeghead
* New TrustedUpdate component for signing/verifying files with a DSA
signature.
2005-03-21 jrandom
* Fixed the tunnel fragmentation handler to deal with multiple fragments
in a single message properly (rather than release the buffer into the
cache after processing the first one) (duh!)
* Added the batching preprocessor which will bundle together multiple
small messages inside a single tunnel message by delaying their delivery
up to .5s, or whenever the pending data will fill a full message,
whichever comes first. This is disabled at the moment, since without the
above bugfix widely deployed, lots and lots of messages would fail.
* Within each tunnel pool, stick with a randomly selected peer for up to
.5s before randomizing and selecting again, instead of randomizing the
pool each time a tunnel is needed.
* 2005-03-18 0.5.0.3 released
2005-03-18 jrandom
* Minor tweak to the timestamper to help reduce small skews
* Adjust the stats published to include only the relevent ones
* Only show the currently used speed calculation on the profile page
* Allow the full max # resends to be sent, rather than piggybacking the
RESET packet along side the final resend (duh)
* Add irc.postman.i2p to the default list of IRC servers for new installs
* Drop support for routers running 0.5 or 0.5.0.1 while maintaining
backwards compatability for users running 0.5.0.2.
2005-03-18 jrandom
* Eepproxy Fix for corrupted HTTP headers (thanks nickster!)
* Fixed case sensitivity issues on the HTTP headers (thanks duck!)
2005-03-17 jrandom
* 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!)
2005-03-16 jrandom
* 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!)
2005-03-14 jrandom
* New strict speed calculator that goes off the actual number of messages
verifiably sent through the peer by way of tunnels. Initially, this only
contains the successful message count on inbound tunnels, but may be
augmented later to include verified outbound messages, peers queried in
the netDb, etc. The speed calculation decays quickly, but should give
a better differential than the previous stat (both values are shown on
the /profiles.jsp page)

* Rather than the fixed resend timeout floor (10s), use 10s+RTT as the
minimum (increased on resends as before, of course).
* Always prod the clock update listeners, even if just to tell them that
the time hasn't changed much.
* Added support for explicit peer selection for individual tunnel pools,
which will be useful in debugging but not recommended for use by normal
end users.
* More aggressively search for the next hop's routerInfo on tunnel join.
* Give messages received via inbound tunnels that are bound to remote
locations sufficient time (taking into account clock skew).
* Give alternate direct send messages sufficient time (10s min, not 5s)
* Always give the end to end data message the explicit timeout (though the
old default was sufficient before)
* No need to give end to end messages an insane expiration (+2m), as we
are already handling skew on the receiving side.
* Don't complain too loudly about expired TunnelCreateMessages (at least,
not until after all those 0.5 and 0.5.0.1 users upgrade ;)
* Properly keep the sendBps stat
* When running the router with router.keepHistory=true, log more data to
messageHistory.txt
* Logging updates
* Minor formatting updates
2005-03-08 jrandom
* More aggressively adjust the clock
2005-03-07 jrandom
* Fix the HTTP response header filter to allow multiple headers with the
same name (thanks duck and spotteri!)
* 2005-03-06 0.5.0.2 released
2005-03-06 jrandom
* Allow the I2PTunnel web interface to select streaming lib options for
individual client tunnels, rather than sharing them across all of them,
as we do with the session options. This way people can (and should) set
the irc proxy to interactive and the eepproxy to bulk.
* Added a startRouter.sh script to new installs which simply calls
"sh i2prouter start". This should make it clear how people should start
I2P.
* Properly expand the HTTP response header buffer (thanks shendaras!)
2005-03-04 jrandom
* Filter HTTP response headers in the eepproxy, forcing Connection: close
so that broken (/malicious) webservers can't allow persistent
connections. All HTTP compliant browsers should now always close the
socket.
* Enabled the GZIPInputStream's cache (they weren't cached before)
* Make sure our first send is always a SYN (duh)
* Workaround for some buggy compilers
2005-03-03 jrandom
* Loop while starting up the I2PTunnel instances, in case the I2CP
listener isn't up yet (thanks detonate!)
* Implement custom reusable GZIP streams to both reduce memory churn
and prevent the exposure of data in the standard GZIP header (creation
time, OS, etc). This is RFC1952 compliant, and backwards compatible,
though has only been tested within the confines of I2P's compression use
(DataHelper.[de]compress).
* Preemptively support the next protocol version, so that after the 0.5.0.2
release, we'll be able to drop protocol=2 to get rid of 0.5 users.
2005-03-02 jrandom
* Fix one substantial OOM cause (session tag manager was only dropping
tags once the critical limit was met, rather than honoring their
expiration) (duh)
* Lots of small memory fixes
* Double the allowable concurrent outstanding tunnel build tasks (20)
2005-03-01 jrandom
* 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.
2005-02-27 jrandom
* Don't rerequest leaseSets if there are already pending requests
* Reverted the insufficiently tested caching in the DSA/SHA1 impl, and
temporary disabled the streaming lib packet caching.
* Reduced the resend RTT penalty to 10s
2005-02-26 jrandom
* Force 1.3-isms on the precompiled jsps too (thanks laberhost)
2005-02-26 jrandom
* Further streaming lib caching improvements
* Reduce the minimum RTT (used to calculate retry timeouts), but also
increase the RTT on resends.
* Lower the default message size to 4KB from 16KB to further reduce the
chance of failed fragmentation.
* Extend tunnel rebuild throttling to include fallback rebuilds
* If there are less than 20 routers known, don't drop the last 20 (to help
avoid dropping all peers under catastrophic failures)
* New stats for end to end messages - "client.leaseSetFoundLocally",
"client.leaseSetFoundRemoteTime", and "client.leaseSetFailedRemoteTime"
2005-02-24 jrandom
* Throttle the number of tunnel rebuilds per minute, preventing CPU
overload under catastrophic failures (thanks Tracker and cervantes!)
* Block the router startup process until we've initialized the clock
2005-02-24 jrandom
* Cache temporary memory allocation in the DSA's SHA1 impl, and the packet
data in the streaming lib.
* Fixed a streaming lib bug where the connection initiator would fail the
stream if the ACK to their SYN was lost.
2005-02-23 jrandom
* Now that we don't get stale SAM sessions, it'd be nice if we didn't
get stale tunnel pools, don't you think?
2005-02-22 jrandom
* Reworked the tunnel (re)building process to remove the tokens and
provide cleaner controls on the tunnels built.
* Fixed situations where the timestamper wanted to test more servers than
were provided (thanks Tracker!)
* Get rid of the dead SAM sessions by using the streaming lib's callbacks
(thanks Tracker!)
2005-02-22 jrandom
* Temporary workaround for the I2CP disconnect bug (have the streaminglib
try to automatically reconnect on accept()/connect(..)).
* Loop check for expired lease republishing (just in case)
2005-02-22 jrandom
* Adjusted (and fixed...) the timestamper change detection
* Deal with a rare reordering bug at the beginning of a stream (so we
don't drop it unnecessarily)
* Cleaned up some dropped message handling in the router
* Reduced job queue churn when dealing with a large number of tunnels by
sharing an expiration job
* Keep a separate list of the most recent CRIT messages (shown on the
logs.jsp). This way they don't get buried among any other messages.
* For clarity, display the tunnel variance config as "Randomization" on
the web console.
* If lease republishing fails (boo! hiss!) try it again
* Actually fix the negative jobLag in the right place (this time)
* Allow reseeding when there are less than 10 known peer references
* Lots of logging updates.
2005-02-20 jrandom
* Allow the streaming lib resend frequency to drop down to 20s as the
minimum, so that up to 2 retries can get sent on an http request.
* Add further limits to failsafe tunnels.
* Keep exploratory and client tunnel testing and building stats separate.
* Only use the 60s period for throttling tunnel requests due to transient
network overload.
* Rebuild tunnels earlier (1-3m before expiration, by default)
* Cache the next hop's routerInfo for participating tunnels so that the
tunnel participation doesn't depend on the netDb.
* Fixed a long standing bug in the streaming lib where we wouldn't always
unchoke messages when the window size grows.
* Make sure the window size never reaches 0 (duh)
2005-02-20 jrandom
* Only build failsafe tunnels if we need them
* Properly implement the selectNotFailingPeers so that we get a random
selection of peers, rather than using the strictOrdering (thanks dm!)
* Don't include too many "don't tell me about" peer references in the
lookup message - only send the 10 peer references closest to the target.
2005-02-19 jrandom
* Only build new extra tunnels on failure if we don't have enough
* Fix a fencepost in the tunnel building so that e.g. a variance of
2 means +/- 2, not +/- 1 (thanks dm!)
* Avoid an NPE on client disconnect
* Never select a shitlisted peer to participate in a tunnel
* Have netDb store messages timeout after 10s, not the full 60s (duh)
* Keep session tags around for a little longer, just in case (grr)
* Cleaned up some closing event issues on the streaming lib
* Stop bundling the jetty 5.1.2 and updated wrapper.config in the update
so that 0.4.* users will need to do a clean install, but we don't need
to shove an additional 2MB in each update to those already on 0.5.
* Imported the susimail css (oops, thanks susi!)
2005-02-17 jrandom
* If the clock is adjusted during a job run, don't act as if the job took
negative time.
2005-02-17 jrandom
* Included the GPL'ed susimail 0.13 by default (thanks susi23!)
2005-02-17 jrandom
* Fixed the braindead tunnel testing logic
* If a large number of tunnels are failing (within the last 5-10 minutes)
and the current tunnel pool's configuration allows it, randomly build a
zero hop tunnel to replace failed tunnels.
* Enable postman's POP3 and SMTP tunnels by default
2005-02-16 jrandom
* Added some error handling when the number of session tags exceeds the
realistic capacity, dropping a random chunk of received tag sets and
conducting some minor analysis of the remaining ones. This is a part
of a pretty serious error condition, and logs as CRIT (if/when people
see "TOO MANY SESSION TAGS!", please let me know the full log line it
puts in the wrapper.log or /logs.jsp)
* Update the addressbook to only write to the published hosts location
if the addressbook's config contains "should_publish=true" (by default,
it contains "should_publish=false")

2005-02-16 jrandom
* (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.
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!)
2005-02-10 smeghead
* Initial check-in of Pants, a new utility to help us manage our 3rd-party
dependencies (Fortuna, Jetty, Java Service Wrapper, etc.). Some parts of
Pants are still non-functional at this time so don't mess with it yet
unless you want to potentially mangle your working copy of CVS.
2005-02-09 duck
* Allow an unneeded newline in the SAM client connection without
disconnecting.
2005-02-07 jrandom
* Fixed a race in the streaming lib's delayed flush algorithm (thanks anon!)
2005-02-06 Sugadude
* Added a filter to the addressbook to remove entries that dont end in ".i2p"
2005-02-03 smeghead
* Added Ant buildfile in apps/fortuna for creating a custom Fortuna PRNG jar
library from GNU Crypto's CVS HEAD sources.
2005-01-26 smeghead
* i2pProxy.pac, i2pbench.sh, and i2ptest.sh are now shipped with the dist
packages and installed to $i2pinstalldir/scripts.
* Added command line params to i2ptest.sh and i2pbench.sh: --gij to run them
using gij + libgcj, and --sourcedir to run them from the source tree
instead of the installation directory.
* Fixed unreachable for() statement clause in the KBucketImpl class that was
causing gcj to toss a compilation warning (jrandom++).
2005-01-26 smeghead
* Added a couple of scripts, i2ptest.sh and i2pbench.sh, to manage the core
tests and benchmarks.
* Routerconsole now builds under gcj 3.4.3.
* Corrected divide by zero error in TunnelId class under gcj (jrandom++).
2005-01-25 smeghead
* Tweaked some classes to enable gcj 3.4.3 to compile the router and
supporting apps (except for the routerconsole which is still being
investigated).
2005-01-24 smeghead
* C#-ification of sam-sharp: interface greatly simplified using delegates
and events; SamBaseEventHandler provides basic implementation and helper
methods but is now optional.
* NAnt buildfile and README added for sam-sharp.
2005-01-23 smeghead
* Port the java SAM client library to mono/C# and released into the
public domain. The 0.1 version of this port is available in CVS as
i2p/apps/sam/csharp/src/I2P.SAM.Client. The other nonfunctional C#
library has been removed.
2005-01-21 Jhor
* Updated jbigi build scripts for OSX.
2005-01-21 jrandom
* Added support for OSX to the NativeBigInteger code so that it will look
in the classpath for libjbigi-osx-none.jnilib. At the moment, that file
is not bundled with the shipped jbigi.jar yet though.
2005-01-18 jrandom
* Increased the max # session tags maintained and decreased slightly the
period over which they are gathered.
2005-01-17 jrandom
* 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.
2005-01-15 cervantes
* Added support to the eepproxy for URLs such as
http://localhost:4444/eepproxy/foo.i2p/bar/baz or even
http://localhost:4444/eepproxy/foo.i2p/?i2paddresshelper=base64
2005-01-15 jrandom
* Caught a series of (previously unhandled) errors caused by requeueing
messages that had timed out on the TCP transport (thanks mae^!)
* Reduce the barrier to dropping session tags on streaming lib resends -
every fourth send should drop the tags, forcing ElGamal encryption. This
will help speed up the recovery after a disconnect, rather than the drop
every fifth send.
* 2005-01-06 0.4.2.6 released
2005-01-06 jrandom
* Added a startup message to the addressbook, printing its version number
to stdout (which is sent to wrapper.config) when it loads.
* Updated the addressbook to reread the config file periodically
* Added orion.i2p to the list of eepsites on the default homepage
2005-01-05 jrandom
* 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.
2004-12-31 ragnarok
* Integrated latest addressbook changes (2.0.3) which include support for
deploying as a .war file with no existing addressbook configuration.
* Updated main build process to bundle the addressbook.war in the
i2pinstall.jar and i2pupdate.zip.
2004-12-31 jrandom
* Speling fxi (thanks digum!)
* Bugfix for the I2PTunnel web interface so that it now properly launches
newly added tunnels that are defined to be run on startup (thanks ugha!)
2004-12-30 jrandom
* Revised the I2PTunnel client and httpclient connection establishment
throttles. There is now a pool of threads that build the I2PSocket
connections with a default size of 5, configurable via the I2PTunnel
client option 'i2ptunnel.numConnectionBuilders' (if set to 0, it will
not throttle the number of concurrent builders, but will launch a thread
per socket during establishment). In addition, sockets accepted but
not yet allocated to one of the connection builders will be destroyed
after 30 seconds, configurable via 'i2ptunnel.maxWaitTime' (if set to
0, it will wait indefinitely).
2004-12-29 jrandom
* Imported Ragnarok's addressbook source (2.0.2) which is built but not
deployed in the i2pinstall.jar/i2pupdate.zip (yet).
* Don't treat connection inactivity closure as a connection error.
2004-12-29 jrandom
* Add in a new keepalive event on each TCP connection, proactively sending
a (tiny) time message every minute or two, as well as killing the
connection if no message has been fully sent within 5 minutes or so.
This should help deal with hung connections from IP address changes.
2004-12-28 jrandom
* Cleaned up the resending and choking algorithm in the streaming lib.
* Removed the read timeout override for I2PTunnel's httpclient, allowing
it to use the default for the streaming lib.
* Revised ack triggers in the streaming lib.
* Logging.
* 2004-12-21 0.4.2.5 released
2004-12-21 jrandom
* Track a new stat for expired client leases (client.leaseSetExpired).
2004-12-21 jrandom
* Cleaned up the postinstall/startup scripts a bit more to handle winME,
and added windows info to the headless docs. (thanks ardvark!)
* Fixed a harmless (yet NPE inspiring) race during the final shutdown of
a stream (thanks frosk!)
* Add a pair of new stats for monitoring tunnel participation -
tunnel.participatingBytesProcessed (total # bytes transferred) and
tunnel.participatingBytesProcessedActive (total # bytes transferred for
tunnels whose byte count exceed the 10m average). This should help
further monitor congestion issues.
* Made the NamingService factory property public (thanks susi!)
2004-12-20 jrandom
* No longer do a blocking DNS lookup within the jobqueue (thanks mule!)
* Set a 60s dns cache TTL, instead of 0s. Most users who used to use
dyndns/etc now just use IP autodetection, so the old "we need ttl=0"
reasoning is gone.
2004-12-19 jrandom
* Fix for a race on startup wrt the new stats (thanks susi!)
2004-12-19 jrandom
* Added three new stats - router.activePeers, router.fastPeers, and
router.highCapacityPeers, updated every minute
2004-12-19 jrandom
* Added a new i2ptunnel type: 'httpserver', allowing you to specify what
hostname should be sent to the webserver. By default, new installs will
have an httpserver pointing at their jetty instance with the spoofed
name 'mysite.i2p' (editable on the /i2ptunnel/edit.jsp page).
2004-12-19 scintilla
* Convert native jcpuid code from C++ to C. This should alleviate build
problems experienced by some users.
2004-12-16 jrandom
* Catch another oddball case for a reset connection in the streaming lib.
* Add a dumpprofile.jsp page, called with ?peer=base64OfPeerHash, which
dumps the current state of that peer's profile. Instead of the full
base64, you can pass in however many characters you have and it will
return the first match found.
2004-12-16 jrandom
* Remove the randomized factor in the tunnel rejection by bandwidth -
we now accept the request if we've allocated less than our limit
and reject it if we've allocated more.
* Stick to the standard capacity scale on tunnel rejection, even for
the 10m period.
* Build the time message at the very last possible moment
2004-12-15 jrandom
* Handle hard disconnects more gracefully within the streaming lib, and
log unmonitored events more aggressively.
* If we drop a peer after connection due to clock skew, log it to the
/logs.jsp#connectionlogs with relevent info. In addition, toss it in
the stat 'tcp.disconnectAfterSkew'.
* Fixed the formatting in the skew display
* Added an ERROR message that is fired once after we run out of
routerInfo files (thanks susi!)
* Set the connect timeout equal to the streaming lib's disconnect timeout
if not already specified (the I2PTunnel httpclient already enforces a
60s connect timeout)
* Fix for another connection startup problem in the streaming lib.
* Fix for a stupid error in the probabalistic drop (rand <= P, not > P)
* Adjust the capacity calculations so that tunnel failures alone in the
last 10m will not trigger a 0 capacity rank.
2004-12-14 jrandom
* Periodically send a message along all I2NP connections with the router's
current time, allowing the receiving peer to determine that the clock
has skewed too much, and hence, disconnect. For backwards compatability
reasons, this is being kludged into a DeliveryStatusMessage (ewww). The
next time we have a backwards compatability break, we can put in a proper
message setup for it.
2004-12-14 jrandom
* Reenable the probabalistic drop on the TCP queues to deal with good old
fashioned bandwidth limiting. However, by default the probability is
rigged to reserve 0% of the queue free - meaning we just aggressively
fail messages in the queue if we're transferring too slowly. That
reservation factor can be increased with 'tcp.queueFreeFactor=0.25'
(or whatever) and the drop code can be disabled with the parameter
'tcp.dropProbabalistically=false'.
* Still penalize a peer on tunnel failure, but don't immediately drop
their capacity to 0.
* More aggressively ACK duplicates
* Randomize the timestamper period
* Display the clock skew on the connection logs when a peer sends it.
* Allow the timestamper to fix skews of up to 10 minutes
* Logging
2004-12-13 jrandom
* Added some error checking on the new client send job (thanks duck!)
* Implemented tunnel rejection based on bandwidth usage (rejecting tunnels
proportional to the bytes allocated in existing tunnels vs the bytes
allowed through the bandwidth limiter).
* Enable a new configuration parameter for triggering a tunnel rebuild
(tunnel.maxTunnelFailures), where that is the max allowed test failures
before killing the tunnel (default 0).
* Gather more data that we rank capacity by (now we monitor and balance the
data from 10m/30m/60m/1d instead of just 10m/60m/1d).
* Fix a truncation/type conversion problem on the long term capacity
values (we were ignoring the daily stats outright)
2004-12-11 jrandom
* Fix the missing HTTP timeout, which was caused by the deferred syn used
by default. This, in turn, meant the I2PSocket creation doesn't fail
on .connect, but is unable to transfer any data in any direction. We now
detect that condition for the I2PTunnelHTTPClient and throw up the right
error page.
* Logging
2004-12-11 jrandom
* 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
2004-12-08 jrandom
* Revised the buffering when reading from the SAM client and writing
to the stream. Also added a thread (sigh) so we don't block the
SAM client from giving us more messages for abnormally long periods
of time.
* Display the router version in the logs on startup (oft requested)
* Fix a race during the closing of a messageOutputStream
2004-12-06 jrandom
* Don't do a 'passive flush' while there are already outbound messages
unacked.
* Show the reseed link if up to 10 peers profiles are active (thanks
dburton!)
2004-12-06 jrandom
* Don't propogate streaming connection failures out to the SAM bridge as
fatal errors.
* Dont barf on repeated I2CP closure.
2004-12-05 jrandom
* Explicitly use "127.0.0.1" to bind the I2CP listener, not the JVM's
getLocalhost call
2004-12-05 jrandom
* Default the I2CP listener to localhost only, unless overridden by
i2cp.tcp.bindAllInterfaces=true (thanks dm!)
* More SAM fixes for things recently broken (whee)
2004-12-05 jrandom
* Fix the recently broken SAM bridge (duh)
* Add a new pair of SAM apps - net.i2p.sam.client.SAMStreamSink and
net.i2p.sam.client.SAMStreamSend, mirroring the streaming lib's
StreamSink and StreamSend apps for transferring files.
* Make the passive flush timer fire more frequently.
2004-12-05 jrandom
* Fixed some links in the console (thanks ugha!) and the javadoc
(thanks dinoman!)
* Fix the stream's passive flush timer (oh, its supposed to work?)
2004-12-03 jrandom
* 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.
