Previous semester: Fall 2011 SBR600 Weekly Schedule

Week 1 (Jan 10) - Introduction



  • About this course
  • Introductions

Intro to SBR600 - Software Build & Release

To Do

By Tuesday, January 17:

  1. Communication Lab
  2. Fedora Installation

Week 2 (Jan 17) - RPM Packaging, Mock, and Koji


Using make

Building from Source

  • Obtaining source code
  • Configuring the build
  • Performing the build
  • Testing the build
  • Installing the built software

RPM Packages

  • Differences between managing RPMS and Installing from Source
    • RPMS provide a database of installed software
      • Let you determine what's installed
      • Automatic management of dependencies
      • Identify the origin of files
      • Permit easy update or removal
      • Enable you to verify installation (useful for spotting file corruption and intrusions)
  • Contents of an RPM Package

The RPM Database

Creating an RPM Package


To Do

By Thursday, January 19:

  1. Build-from-Source Lab
  2. RPM-Writing Lab
  3. Send your SSH public key to your professor so he can create accounts for you on the CDOT Development Systems.


Mock: Testing BuildRequires

It's often difficult to get the BuildRequires in a spec file exactly right, because it's easy to overlook packages that are coincidentally installed on the machine. Mock is used to test that the BuildRequires for a package are complete and accurate, by creating a bare-bones chroot environment containing only the basic build packages plus any packages indicated by BuildRequires lines in the spec file.

Koji: Testing on Multiple Architectures

Most developers and packagers have access to only a small number of system architectures (for example, a developer might have access to 64-bit AMD/Intel, but not have access to 32-bit AMD/Intel, s390 mainframe, PowerPC, or ARM systems). The Koji build system provides a mechanism for building a package in mock on one or more remote systems.

To Do

By Tuesday, January 24:

  1. SBR600 Mock and Koji Lab

Week 3 (Jan 24) - The Fedora Build System


Guest Lecturer: Dennis Gilmore, Fedora Release Engineer, Red Hat, Inc.

Dennis is Fedora's release engineer. He will be visiting Seneca Centre for Development of Open Technology (CDOT) this week and has agreed to give a guest lecture on Tuesday.

How Koji Works


  • Work on packages

= Week 4 (Jan 31)


Project Selection

This is a project-based course. These projects involve participation in an open-source community.

  • Projects are listed on the SBR600 Potential Projects page.
  • Select two or three projects that are of interest to you.
    • Do some initial research into what the project involves.
      • Find out who to talk to in the community (start with the initial contacts listed on the project description)
      • See what work has already been done related to that project. Check the Seneca wiki for work by previous SBR600 semesters, the upstream project's wiki and mailing list archives for information about the current state of the project, and the web for related information (similar projects being done by other groups).
      • Join the mailing lists and IRC channels of the upstream community.
    • Update the Winter 2012 SBR600 Participants table with your project information, according to the instructions at the top of that page.
  • On Thursday we'll sort out project conflicts.
  • Your professor will approve your project selection via the participants page.
  • Link your project title on the participants page to a page of the same name to create a project page. Copy the contents of the Sample Project page to your project page and fill in the details.

Over the next 2 weeks, finalize your project plans and get started on your project:

  • The project page must be filled in, including your 0.1, 0.2, and 0.3 targets.
    • Release 0.1: Proof of concept (e.g., a first draft of a package, a basic script, infrastructure set up on a test system) - Note that this must include the release of something, not just research, and must be done in consultation with the community.
    • Release 0.2: Initial working state - Whatever you are working on -- package, script, infrastructure configuration -- should be working, although it may not be feature-complete, fully deployed, or fully documented. Feedback from the community should be solicited. If there is a review process required to submit upstream, it should be started.
    • Release 0.3: Completed working state - The work is complete and documented. Any upstream review, whether formal or informal, has been completed, feedback has been incorporated into the project, and the work has been committed been
  • You must have a strategy in place for reaching your targets.

You will make a brief (3-5 minute) presentation of your project plans on Thursday, February 9.
