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.

2005-03-23  jrandom
    * 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)

2005-03-11  jrandom
    * 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
