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

Tuesday, 22 March 2011

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
