Use context random for shuffle; other cleanups

  - Rework PeerID class so it depends only on peer desthash, since
    peer ID is not available with compact format. Implement deferred
    lookup of destination.
  - Implement compact tracker requests and response handling
    (may not be the final format)
  - Fix Peer hashCode()
  - Java 5

- i2psnark webfrontent configuration of startup delay
- default startup delay 3 minutes
- new config variable in i2psnark.config: i2psnark.startupDelay

      - Add tunnel config dropdowns
      - Comment out old proxy stuff

      - New I2PSocketEepGet fetches through existing tunnels
        rather than through the proxy
      - Use new eepget for i2psnark
      - Add a fake user agent for non-proxied fetches
      - Cleanups

    * Code Janitor time! Many fixes and documenting fixes that should be
      done in the future. for the most part, this is a general code cleanup.
    * On smaller/embedded systems, the "final" keyword cleanups will have
      more of an impact than on larger systems.
    * Document missing hashCode() methods.
    * Unhide more variables to make code easier to read.

Eliminate all uses of the current working directory, and
set up multiple directories specified by absolute paths for various uses.

Add a WorkingDir class to create a user config directory and
migrate files to it for new installs.
The directory will be $HOME/.i2p on linux and %APPDIR%\I2P on Windows,
or as specified in the system property -Di2p.dir.config=/path/to/i2pdir
All files except for the base install and temp files will be
in the config directory by default.
Temp files will be in a i2p-xxxxx subdirectory of the system temp directory
specified by the system property java.io.tmpdir.

Convert all file opens in the code to be relative to a specific directory,
as specified in the context. Code and applications should never open
files relative to the current working directory (e.g. new File("foo")).
All files should be accessed in the appropriate context directory,
e.g. new File(_context.getAppDir(), "foo").

The router.config file location may be specified as a system property on the
java command line with -Drouter.configLocation=/path/to/router.config
All directories may be specified as properties in the router.config file.

The migration will copy all files from an existing installation,
except i2psnark/, with the system property -Di2p.dir.migrate=true.
Otherwise it will just set up a new directory with a minimal configuration.

The migration will also create a modified wrapper.config and (on linux only)
a modified i2prouter script, and place them in the config directory.

There are no changes to the installer or the default i2prouter, i2prouter.bat,
i2prouter, wrapper.config, runplain.sh, windows service installer/uninstaller,
etc. in this checkin.


    *  Directories. These are all set at instantiation and will not be changed by
    *  subsequent property changes.
    *  All properties, if set, should be absolute paths.
    *
    *  Name	Property 	Method		Files
    *  -----	-------- 	-----		-----
    *  Base	i2p.dir.base	getBaseDir()	lib/, webapps/, docs/, geoip/, licenses/, ...
    *  Temp	i2p.dir.temp	getTempDir()	Temporary files
    *  Config	i2p.dir.config	getConfigDir()	*.config, hosts.txt, addressbook/, ...
    *
    *  (the following all default to the same as Config)
    *
    *  Router	i2p.dir.router	getRouterDir()	netDb/, peerProfiles/, router.*, keyBackup/, ...
    *  Log	i2p.dir.log	getLogDir()	wrapper.log*, logs/
    *  PID	i2p.dir.pid	getPIDDir()	wrapper *.pid files, router.ping
    *  App	i2p.dir.app	getAppDir()	eepsite/, ...
    *
    *  Note that we can't control where the wrapper actually puts its files.

All these will be set appropriately in a Router Context.
In an I2P App Context, all except Temp will be the current working directory.

Lightly tested so far, needs much more testing.

      will not be rescheduled or cancelled, to reduce SimpleTimer
      lock contention

    - Don't create SnarkManager instance until first call,
      so it doesn't create the i2psnark dir, read the config,
      etc., for single Snark instances.
    - Don't read i2psnark.config twice; fix setting
      i2psnark.dir
    - More Snark constructor changes for calling from router
    - Make max connections per torrent configurable

    - Remove static instances of I2PSnarkUtil, ConnectionAcceptor,
      and PeerCoordinatorSet
    - Convert static classes in Snark to listeners
    - Fix Snark to work in single torrent mode again
    - Should now work with multiple single Snarks

  - Refactor to allow running a single Snark without a SnarkManager again,
    by moving some things from SnarkManager to I2PSnarkUtil,
    having Snark call completeListener callbacks,
    and having Storage call storageListener callbacks.
    This is in preparation for using Snark for router updates.
    Step 2 is to allow multiple I2PSnarkUtil instances.
  - Big rewrite of Storage to open file descriptors on demand, and
    close them when unused, so we can support large numbers of torrents.

    * NTCP: Don't drop a connection unless both directions are idle;
            Fix idle time for outbound connections
    * Outbound message: Make sure cached lease is in current leaseSet
    * Stats: Put all NetworkDatabase stats in same group
    * TunnelPool: Stop building tunnels and leaseSets after client shutdown
    * i2psnark: Add locking to prevent two I2CP connections

      - Add support for secondary open trackers
      - Refactor and simplify the TrackerClient code
      - Add welterde's tracker to the default list
      - Don't have eepget retry announces
      - Slow down tracker contacts if they've failed for a while
      - Add some debug support showing connections (?p=2)

      - Exclude floodfill peers
      - Tweak the HighCap vs. NonFailing decision
    * i2psnark: Increase retries for .torrent fetch
    * IRC Proxy: Prevent mIRC from sending an alternate DCC request
      containing an IP
    * readme.html: Reorder some items
    * Stats: Add some more required stats
    * Streaming lib: Fix slow start to be exponential growth,
      fix congestion avoidance to be linear growth.
      Should speed up local connections a lot, and remote
      connections a little.

    * i2psnark: increase streaming lib write timeout to 240 sec and change
      timeout action from "ping" to "disconect", as the fix in .30 to
      honor options on outbound connections led to hung outbound connections
      (bitfield never transmitted, connection never dropped)

    * Add stats for individual tunnel rates (nice when graphed)
    * i2psnark: Fix outbound tunnel nickname

zzz authored 18 years ago and zzz committed 18 years ago

    * i2psnark: Make max total uploaders configurable (thanks Amiga4000!)

zzz authored 18 years ago and zzz committed 18 years ago

    * Streaming lib changes to improve upstream performance during congestion:
    *   Change min window size from 12 to 1
    *   Change max timeout from 10 to 45 sec
    *   Change initial timeout from 10 to 15 sec
    *   Change intial window size for i2psnark from 12 to 1
    *   Change slow start growth rate for i2psnark from 1/2 to 1

    * HTML fixes in Syndie to work better with opera (thanks shaklen!)
    * Give netDb lookups to floodfill peers more time, as they are much more
      likely to succeed (thereby cutting down on the unnecessary netDb
      searches outside the floodfill set)
    * Fix to the SSU IP detection code so we won't use introducers when we
      don't need them (thanks Complication!)
    * Add a brief shitlist to i2psnark so it doesn't keep on trying to reach
      peers given to it
    * Don't let netDb searches wander across too many peers
    * Don't use the 1s bandwidth usage in the tunnel participation throttle,
      as its too volatile to have much meaning.
    * Don't bork if a Syndie post is missing an entry.sml

    * Switch from the bouncycastle to the gnu-crypto implementation for
      SHA256, as benchmarks show a 10-30% speedup.
    * Removed some unnecessary object caches
    * Don't close i2psnark streams prematurely

jrandom authored 19 years ago and zzz committed 19 years ago

    * Merged in the i2p_0_6_1_10_PRE branch to the trunk, so CVS HEAD is no
      longer backwards compatible (and should not be used until 0.6.1.1 is
      out)

    * 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)

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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)
