Project Overview
TopCoder Competition Engine is a system used for Single Round Matches (SRM) and Marathon Matches (MM).
Recently, the whole system is targeted to be built for Java 5, which is end of its life already. You can check http://www.oracle.com/technetwork/java/eol-135779.html
Competition Task Overview
The purpose of this contest, is seeking to update Java 7, which is mature now, and evalute that nothing is broken. So you are expecting to carry out the following tasks.
Install JDK 7
You are expected to install JDK 7 update 55, and update the JAVA_HOME settings for various accounts related to, like apps, farm, deployer, mm etc.
JBoss Upgrade
Currently, JBoss 4.0.5 is used for deploying ejbs, We'd like to upgrade it to JBoss 6.1.0.
Notes, the jboss services are used by marathon match web interface, please make sure the marathon match interface is still working properly.
Tomcat Upgrade
Currently, Apache Tomcat 5.5.27 is used for deploying farm deployer, we'd like to upgrade it to use Apache Tomcat 7.0.53.
Verification
The SRM Problem Guide and MM Problem Guide are provided in forum, please make sure all steps and all languages are working properly.
Winner Responsibility
Winner will be responsible to create pull request in final fix phase, and help with the merge.
About Code Base
For the code under /home/apps/dev directory, some are hosted in internal svn repositories, some are hosted in private repositories in github.
You can check Source Code Management For TopCoder Competition Engine - TopCoder Wiki
For SVN Access, please send request to support@topcoder.com, For github access, please post your github account in forum to ask PM to grant you access.
Arena VM Usage
Root access will be granted to make you easy to install JDK 7.
Before asking your own VM, you need to have a public key on your profile before asking for the VM.
You can find more details on how to generate a key http://apps.topcoder.com/wiki/display/projects/Generate+SSH+Key and how to connect using it http://apps.topcoder.com/wiki/display/projects/Connect+Using+SSH+Key.
Please reference http://apps.topcoder.com/wiki/display/docs/Competition+Engine+VM+Setup for general usage.
Previously, we have made several update for the Arena VM. So when the Arena VM allocated is available for you, there is a problem and a SRM contest already setup, you can reuse that for testing.
