Java library for ED2K(eDonkey) networks

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,....
