- Fixes and cleanups when NTCP and/or UDP transports disabled
- More TCP removal cleanup
- Clean up bandwidth limiting, centralize defaults
- Force burst to be >= limit
- Increase default bw to 48/24, burst 64/32
- Restrict peers requiring introducers from inbound tunnels,
since it's slow and unreliable... and many of them advertise
NTCP, which seems unlikely to work
- Provide warning on summary bar if firewalled with inbound NTCP enabled
* Stats: Remove the bw.[send,recv]Bps[1,15]s stats unless
log level net.i2p.router.transport.FIFOBandwidthLimiter >= WARN
at startup (you didn't get any data unless you set the log level anyway)
* oldstats.jsp: Don't put 2 decimal places on integer event counts
* Remove the Internals link from the menu bar
* i2psnark: Extend startup delay from 1 to 3 minutes
* Improve the multitransport shitlisting (thanks Complication!)
* Allow routers with a capacity of 16-32KBps to be used in tunnels under
the default configuration (thanks for the stats Complication!)
* Properly allow older router references to load on startup
(thanks bar, Complication, et al!)
* Add a new "i2p.alwaysAllowReseed" advanced config property, though
hopefully today's changes should make this unnecessary (thanks void!)
* Improved NTCP buffering
* Close NTCP connections if we are too backlogged when writing to them
* Correct a misnamed property in SummaryHelper.java
to avoid confusion
* Make the maximum allowance of our own concurrent
tunnel builds slightly adaptive: one concurrent build per 6 KB/s
within the fixed range 2..10
* While overloaded, try to avoid completely choking our own build attempts,
instead prefer limiting them to 1
* Process inbound tunnel requests more efficiently
* Proactively drop inbound tunnel requests if the queue before we'd
process it in is too long (dynamically adjusted by cpu load)
* Adjust the tunnel rejection throttle to reject requeusts when we have to
proactively drop too many requests.
* Display the number of pending inbound tunnel join requests on the router
console (as the "handle backlog")
* Include a few more stats in the default set of graphs
* Run the peer profile coalescing/reorganization outside the job queue
(on one of the timers), to cut down on some job queue congestion. Also,
trim old profiles while running, not just when starting up.
* Slightly more sane intra-floodfill-node netDb activity (only flood new
entries)
* Workaround in the I2PTunnelHTTPServer for some bad requests (though the
source of the bug is not yet addressed)
* Better I2PSnark reconnection handling
* Further cleanup in the new tunnel build process
* Make sure we expire old participants properly
* Remove much of the transient overload throttling (it wasn't using a good
metric)
* Add a new Status: line on the router console - "ERR-ClockSkew", in case
the clock is too skewed to do anything useful (check the year and month,
not just the hour and minute).
* Fixed the read/write timeouts in the streaming lib (so that it actually
honors them now)
* Minor I2PSnark cleanups (no read timeout, more careful shutdown and
torrent closing)
* Handle an oddball tunnel creation failure (thanks Xunk)
* Create different strategies for exploratory tunnels (which are difficult
to create) and client tunnels (which are much easier)
* Gradually increase number of parallel build attempts as tunnel expiry
nears.
* Temporarily shorten attempted build tunnel length if builds using
configured tunnel length are unsuccessful
* React more aggressively to tunnel failure than routine tunnel
replacement
* Make tunnel creation times randomized - there is existing code to
randomize the tunnels but it isn't effective due to the tunnel creation
strategy. Currently, most tunnels get built all at once, at about 2 1/2
to 3 minutes before expiration. The patch fixes this by fixing the
randomization, and by changing the overlap time (with old tunnels) to a
range of 2 to 4 minutes.
* Reduce number of excess tunnels. Lots of excess tunnels get created due
to overlapping calls. Just about anything generated a call which could
build many tunnels all at once, even if tunnel building was already in
process.
* Miscellaneous router console enhancements
2005-10-07 jrandom
* Include the 1 second bandwidth usage on the console rather than the
1 minute rate, as the 1 second value doesn't have the 1m/5m quantization
issues.
* Allow reseeding on the console if the netDb knows less than 30 peers,
rather than less than 10 (without internet connectivity, we keep the
last 15 router references)
* Reenable the x-i2p-gzip HTTP processing by default, flushing the stream
more aggressively.
* Show the status that used to be called "ERR-Reject" as "OK (NAT)"
* Reduced the default maximum number of streaming lib resends of a packet
(10 retransmits is a bit much with a reasonable RTO)
* Test the router's reachability earlier and more aggressively
* Use the low level bandwidth limiter's rates for the router console, and
if the router has net.i2p.router.transport.FIFOBandwidthLimiter=INFO in
the logger config, keep track of the 1 second transfer rates as the stat
'bw.sendBps1s' and 'bw.recvBps1s', allowing closer monitoring of burst
behavior.
* Deployed the peer testing implementation to be run every few minutes on
each router, as well as any time the user requests a test manually. The
tests do not reconfigure the ports at the moment, merely determine under
what conditions the local router is reachable. The status shown in the
top left will be "ERR-SymmetricNAT" if the user's IP and port show up
differently for different peers, "ERR-Reject" if the router cannot
receive unsolicited packets or the peer helping test could not find a
collaborator, "Unknown" if the test has not been run or the test
participants were unreachable, or "OK" if the router can receive
unsolicited connections and those connections use the same IP and port.
* Display the average clock skew for both SSU and TCP connections
2005-08-07 jrandom
* Fixed the long standing streaming lib bug where we could lose the first
packet on retransmission.
* Avoid an NPE when a message expires on the SSU queue.
* Adjust the streaming lib's window growth factor with an additional
Vegas-esque congestion detection algorithm.
* Removed an unnecessary SSU session drop
* Reduced the MTU (until we get a working PMTU lib)
* Deferr tunnel acceptance until we know how to reach the next hop,
rejecting it if we can't find them in time.
* If our netDb store of our leaseSet fails, give it a few seconds before
republishing.
* 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.
* 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
* 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!)
* 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.
* (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!)
* Bundle the configuration necessary to run an eepsite out of the box
with Jetty - simply edit ./eepsite/docroot/index.html and give people
the key listed on the I2PTunnel configuration page, and its up.
plus minor bugfixes / refactoring / logging
- sendsPerFailure: how many partial sends we make when they all fail
- timeoutCongestionInbound: describes how much faster than our average speed we were receiving data when each partial send timed out (in Bps)
- timeoutCongestionMessage: our send processing time when each partial send timed out (in ms)
- timeoutCongestionTunnel: our tunnel test time when each partial send timed out (in ms)
- participatingMessagesProcessedActive: # of messages more than the (most recent) average that a tunnel we were participating in transmitted (for tunnels with more than the average)
* updated to use Writer for rendering the console, so we can do partial writes (and hopefully help debug some kooky threading bugs on kaffe)
* Update for the SDK reconnection to deal with overflow.
* Web improvements (@ not # on the /logs.jsp [thanks ugha!] and fixed the
rounding on lifetime bandwidth used [thanks gott!]).
2004-09-08 jrandom
* Updated the "Active:" peer count to display the # of connections as well
as the number of recently active router identities.
* Implement some basic updating code - on startup, if there is a file named
"i2pupdate.zip" in the I2P installation directory, extract it, delete it,
then restart.
* Added an ugly little script to allow launching the router on win9x
machines without a dos box (using javaw to run a .bat file).
* Logging updates.
* Updated VERSION constants to 0.4.0.1
* apply oOo's patch for beautifying the new console w/ links to a shitlisted peer's netDb entry
* apply oOo's patch to clean up the peer shitlist count more aggressively
* apply oOo's patch to allow removing lines via /configadvanced.jsp
* apply oOo's patch to clean up the memory usage display
* apply oOo's patch to include log messages on /logs.jsp most recent first, rather than last
* get rid of the netDb key shitlist (its a bad idea, better solution coming soon)
