to mitigate effects of large pieces and allow them to
become interesting faster (ticket #2473)

Implement variable timeout
Hardcode handshake bytes
Log tweaks

Some UI cleanup still to do

when calculating global uploader limit, to allow more upload slots,
especially when some torrents are stalled.
Convert some shared fields to atomics for concurrency.

close files faster based on file count (tickets #1626, #1671)
Remove dup synchs

Add creation date to created torrents
log tweaks
more test cases

   - Store seed/leech status in DHT tracker (ticket #1280)
   - Increase max received DHT nodes (Vuze sends more than K)
   - Recognize not-registered message from diftracker
   - Fix bug in DHT unannounce()

- Protect against null DHT races
- Add message about restarting tunnel when DHT config changes
- Add DHT size to table totals

   - Don't send a keepalive to a peer we are going to disconnect
   - Disconnect peer when idle a long time
   - PeerCheckerTask cleanup
   - Static ref cleanup
   - Don't show a downloaded torrent file as "seeding"
   - Better torrent file download icon (from Silk, same license as the others)

- Disable KRPC
- Shorten tracker string

  - Update session options when max bandwidth changes
  - BufferedStream cleanup and comments
  - torrent name display tweak
  - findbugs

- Announce peers to local tracker
- Ping node on port reception
- More info on directory pages
- Cleanups

and lots of prep for lack of metainfo and storage.

      - Fix NPE and other partials bugs
      - More extension message stubbing
      - Log tweaks

      - Drop queued outbound requests when choked
      - Redo some data structures and locking to hopefully prevent deadlock
      - Memory reduction part 3: Return partial pieces to PeerCoordinator when choked

      - More listing fixes
      - Revert choker change
      thx 'backup' !

      - Choke slower when at bandwidth limit
      - Fix completion % for small files
      - Use Random from context

    * i2psnark debug logging tweak

    - 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.

    * TunnelPeerSelectors:
       - Re-enable strict ordering of peers,
         based on XOR distance from a random hash
       - Restrict peers with uptime < 90m from tunnels (was 2h),
         which is really 60m due to rounding in netDb publishing.
    * i2psnark:
       - Limit max pipelined requests from a single peer to 128KB
         (was unlimited; i2p-bt default is 5 * 64KB)
       - Increase max uploaders per torrent to 6 (was 4)
       - Reduce max connections per torrent to 16 (was 24) to increase
         unchoke time and reduce memory consumption
       - Strictly enforce max connections per torrent
       - Choke more gradually when over BW limit

    * i2psnark changes to improve upload performance:
    *  Implement total uploader limit (10)
    *  Don't timeout non-piece messages out
    *  Change chunk size to 32K (was 64K)
    *  Change request limit to 64K (was 256K)
    * i2psnark: Disconnect from seeds when complete

    * i2psnark: More choking rotation tweaks
    * Improve performance by not reading in the whole
      piece from disk for each request. A huge memory savings
      on 1MB torrents with many peers.

zzz authored 18 years ago and zzz committed 18 years ago

    * i2psnark: Improvements for torrents with > 4 leechers:
      choke based on upload rate when seeding, and
      be smarter and fairer about rotating choked peers.
    * Handle two common i2psnark OOM situations rather
      than shutting down the whole thing.
    * Fix reporting to tracker of remaining bytes for
      torrents > 4GB (but ByteMonsoon still has a bug)

zzz authored 18 years ago and zzz committed 18 years ago

    * i2psnark: Implement retransmission of requests. This
      eliminates one cause of complete stalls with a peer.
      This problem is common on torrents with a small number of
      active peers where there are no choke/unchokes to kickstart things.

    * i2psnark: Implement basic partial-piece saves across connections
    * i2psnark: Implement keep-alive sending. This will keep non-i2psnark clients
      from dropping us for inactivity but also renders the 2-minute transmit-inactivity
      code in i2psnark ineffective. Will have to research why there is transmit but
      not receive inactivity code. With the current connection limit of 24 peers
      we aren't in any danger of keeping out new peers by keeping inactive ones.
    * i2psnark: Increase CHECK_PERIOD from 20 to 40 since nothing happens in 20 seconds
    * i2psnark: Fix dropped chunk handling
    * i2psnark: Web rate report cleanup
