What's New?

Note that kaariboga is work in progress. This means: many bugs and many changes in the future.

2006-09-26

• Some minor code changes, because Kaariboga was no longer compatible to current Java versions.
• Made the developer version the standard version.

2003-02-09

• Developer version: The package org.kaariboga.io is now used for input/output operations. I have removed the threads for sending and receiving messages from KaaribogaBase and socket access from KaaribogaClassLoader. This makes the code a lot more cleaner and open for extensions.

2002-09-01

• Made the developer version the current version.
• Updated documentation.

2002-08-28

• Developer version: new package org.kaariboga.io. This is a first step towards a restructuring of input/output operations. The package inludes a new class called DeliverySerice, which should be used for network traffic in the future. This makes it easy to add new kinds of protocols.
• Developer version: new package org.kaariboga.domainserver The new domain server replaces the old boserver. Start with java org.kaariboga.domainserver.Main
• Developer version: new package org.kaariboga.util including a static Log class and a simple timer. The Log class makes it possible to write logging messages to a file and use different logging levels.

2002-06-16

• Made the developer version the current version.
• Bug fixes to the domain plug-in.
• Agents, that used a domain, now use the domain plug-in.
• Minor changes to the domain server. Several KaaribogaBases on one host are allowed now. This makes it possible to run a full testing environment with several bases on a single computer. .

2001-07-30

• Developer version: Plug-in concept implemented.
• Developer version: New agent HelloPlugInAgent to demonstrate the use of a plug-in.

2001-07-09

• Developer version: Bug fix: Messages to local base were not handled correctly.

2001-06-03

• Developer version: Bug fixes to the network code. Should be more reliable, now.

2001-03-27

• Developer version: The server now supports dynamic IP addressing.

2001-02-06

• Developer version: Minor changes and bug fixes.

2001-01-07

• Developer version: Name spaces for agents are obsolete. The current developer version provides a Java classpath like mechanism to search for agents. The agents are stored in proper directory structures resembling their package names.
• Developer version: Agents can now be loaded using a normal file open dialog.

2000-12-03

• Developer version: The Boga server now has a menu for going on- and offline. This is intended for people who want to use the server at home with dynamic IP addressing. Determing the dynamic IP address is still not ready.

2000-11-12

• Developer version now available through the web pages.
• Developer version: The domain server (BoServer) no longer broadcasts the list of all servers in the domain every time a server connects or disconnects
• Developer version: The domain server handles additional messages, that servers can use to determine their own IP address. This is needed for dynamic IP addressing.

2000-10-03

• Much enhanced version of the Kaariboga Guide.
• Mark's latest changes. This makes it possible to create a base class by deriving it from the current KaaribogaBase.
• Some changes on the web pages. The download section is now split into several parts that separate source code and documentation.

2000-09-19

• First version of the Kaariboga Guide. It is rather incomplete, but I hope, it will provide some help to get into Kaariboga.

2000-08-27

• Mark's latest bug fixes, including the class loading bug that crawled in when moving kaariboga to org.kaariboga.
• It is now possible to run two servers on one computer without code modifications. When sending an agent you can simply add the port number to the address, for example 192.168.0.1:10102.
• KaariboagaInputStream and KaaribogaOutputStream are public now.

2000-08-06

• Mark Jelasity has done a lot of code clean up in the core classes, added new comments and removed historical junk.
• Mark also pointed out, that the counter example does not work on Linux JVMs, that use green threads. According to his advice I have set a lower priority to fix this.
• Package kaariboga moved to org.kaariboga to comply with the standard. Let's hope, that everything still works.

2000-07-11

• Kaariboga discussion group opened. This group is intended for all people, who want to help in the developement process, have problems with the installation or are just curious.
• Kaariboga has moved from the University of Bielefeld to it's new home at the projectory.

2000-02-06

• Usage Scenarios totally rewritten. Lots of new pictures for illustration.

1999-12-04

• All configuration files are now in kaariboga/config/.
• Security improvements
  • Package security removed ;-).
  • The KaaribogaClassLoader now extends java.security.SecureClassLoader.
  • Security setting are defined in the kaariboga.policy file. Please check and modify to meet your demands. There are also some documented example files in the kaariboga/config/ dirctory.
  • The server must be started with
    java -Djava.security.manager -Djava.security.policy=kaariboga/config/kaariboga.policy kaariboga.server.Boga
    for the security settings to take effect. If you start the server the old way with java kaariboga.server.Boga there is no longer a security manager installed! All agents are granted all access rights!

Jul.15.1999

• Installation instructions improved.
• New agent: Reproducer simulates rise and fall of an agent population.
• More sections in the tutorial: Exchanging Messages between mobile agents and self reproduction.
• Broken links in the navigation bars fixed.

Jun.14.1999

• Configuration files should work on all systems now.
• Kaariboga Distribution available as tarball.
• New package kaariboga.security but not much work done yet.
• Moved security manager from core to kaariboga.security.KbSecurityManager.

Jun.10.1999

• Two new classes demonstrate message exchanging between kaariboga agents:
  • MessageReceiver prints out any message he gets.
  • MessageSender sends a message to every agent on the local server.
• New constructor for KaaribogaAddress that could be used for message delivery on the local host.
• Bug fixes:
  • Some messages types could not be delivered because of wrong type conversions in KaaribogaBase.
  • The Boga server always believed that there was an active domain server online.
