Interlude
Tuesday, 22 March 2011
Was dm Server Mature?
• Users in production on v1 & v2
• Principled design

• Extensive test suite (with CI)
• Based on, and influencing, standards

Why donate it?
• Remove adoption inhibitors
• GPL
• Single vendor
• Collaborate on usability
• Build
• Application development tooling

Why Eclipse.org?
• Permissive license
• Governance & IP process
• Built on Equinox & Eclipse
• EclipseRT needed a runtime

Eclipse IP Process• Scrutiny
• Source code
• License
• Pedigree
• Contribution & dependencies
Tuesday, 22 March 2011
IP Process Costs
•Raised 200 CQs
•Deleted 2 dependencies
•Tweaked 3rd party licensing
Tuesday, 22 March 2011
IP Process Benefits• Assured license/pedigree
• Recorded dependencies
• Improved licensing, e.g.
• JWebUnit LGPL
• mime.types file in Spring
Tuesday, 22 March 2011
IP Process Improvements• Clarify:
• Downstream distribution
• “Works with” dependencies
• Policy for build/test dependencies
• Automate release checks (WIP)

Infrastructure
Tuesday, 22 March 2011
Build/Test Infrastructure
•Moved CI to hudson.eclipse.org
•Tool issues
•False positives
•Sharing vs stability
•Virtualisation?
Tuesday, 22 March 2011
Search Infrastructure
• Private OpenGrok
• Too much code to remember
• 22 git repos
• No search at eclipse.org
• Public OpenGrokhttp://virgo-opengrok.springsource.org/

Moving the Community• Generally willing
• Incompatibilities
• Package names
• Dropped function
• Migration to Virgo 2.1
• Minimised
• Migration notesTuesday, 22 March 2011
Effect on Committers• JIRA replaced by bugzilla + Acunote
• Distributed sprint planning
• Concurrent sprints
