Fedora
Fedora. An open source operating system using RPM-based, built on top of the Linux kernel. It is developed and maintained by a community-support known as the Fedora Project which is sponsored by Red Hat. The Fedora Project's mission is "To lead the advancement of free and open source software and content as a collaborative commuinty." Fedora's main aim is to be a leader in the use and distrbution on software designed as open source.
= The Arm Architecture =
Koji Hub - an XML-RPC server that receives and relies upon calls from the Koji Builder Daemons and other Koji components to initiate communications.
Koji Web - an interactive web interface that runs on mod_python modules in the Apache Web Server. The Koji Web provides an interface for Koji users to see the status of queued builds and information for trouble shooting unsuccessful build attempts.
Koji Builder Daemon - the build daemon that runs on each of the Koji build machines and is responsible for polling the Koji Hub for build requests. Once a request is received for the Koji Hub the Koji Builder will initiate a test build of the software package ensuring there are no errors, if errors are detected they are logged for further analysis.
Components Required By Koji
Apache Web Server - The most popular web server on the internet Apache is responsible for serving the pages provided by the Koji Web scripts. Apache is configured to use a variety of modules including SSL and mod_python. The SSL modules facilitates authentication of users and the different components of the Koji Build System.
PostgreSQL - PostgreSQL is the back-end database used by the Koji Build System. It stores tables of information including users, packages and build categories.
Problems Encountered
- Problems using the PostgreSQL database
- After what appeared to be a successful installation and configuration, Koji builders were listed as not being fully functional, this appeared to be an issue with the Koji Hub but was later determined to be a lack of disk space on the Koji builders.
- Authentication using SSL certificates
- Various configuration issues
Results
At the close of the semester we currently have a functional Koji Build system. The Koji Hub is successfully dispatching packages to the Koji builder Daemons and Kojira is creating new repositories for use with the ARM architecture. Eight VM's and the Open-RD Client are online and are listed as Ready and Enable using the Koji command line tool and the web interface through Koji Web.
