* 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.
