Java library for ED2K(eDonkey) networks

Build status

Why Java?

Main goal - native application for Android platform. Lighter, faster, more user friendly and convenient than current Mule for Android.

Techniques

  • Async network I/O using Java NIO
  • Async disk I/O operations emulation via one single thread executor service per session
  • Project structure inspired by libed2k

Implemented features

  • Packets parsing engine
  • Alerts system
  • Exception system with one type of exception and error code for each problem
  • Search on servers(with all parameter types), search related, search more
  • Downloading parts of files
  • Downloading compressed parts of files(not recommended as default!)
  • Connections policy
  • Naive piece picker optimized to download fist and last pieces first for preview feature
  • Naive piece manager - online pieces hash calculation and hash verification during downloading
  • KAD search for keywords and file sources

What next

  • Stable code, fixing bugs, increase performance
  • Advandced piece picker and piece manager
  • Completed KAD support including firewalled usage and buddy system.
  • Support publishing in KAD and responses to search requests

Building Gradle

Maven build was removed. Gradle is only supported build system.

  1. cd jed2k
  2. open multi module Gradle project - settings.gradle

Testing

You can use simple console downloader module "console". Before usage you have to set incoming directory as first parameter. Do not use double quotes in commands below - there are for mark parameters. Some commands(much more available - see in code):

  • connect to server, default port 4661: connect "server_address_or_ip" [port]
  • search on server: search "search_phrase"
  • search on server: search "search_phrase" dataSize "limit_in_mb"
  • save search results: save
  • load search results: restore
  • show search results: print
  • create transfer: load "hash" "size" "filepath"
  • create transfer: load "emule_link"
  • create transfer: load "number of search"
  • delete transfer: delete "hash"
  • exit application: quit

Additional tool for testing DHT: Kad.java application with own commands system

Special case - trial session - fixed sources addresses. Setup -Dsession.trial=true, -Dsession.peers=a.b.c.d:port,....

Help

If you know Java/C++, Android or Java for Android, use eMule or simply would like help project - welcome 😄
