Review of Last Meeting

Long-Term Support (LTS)

  • Andrew Ross to explain goals, concept and current status
    • Common Build Infrastructure (CBI): An evolution of PDE, Athena etc into a Continuous Integration (CI) facility operated by Eclipse Foundation
      • Make it easy to build, easier to contribute AND enable LTS: Prototype ready NOW
      • Get Eclipse Platform to build at Eclipse.org with Maven (worked on by Igor Fedorenko of Sonatype) - CBI Wiki, mailto:cbi-dev@eclipse.org
    • Why LTS: No single company can support all of Eclipse, but want to build a marketplace for support
      • Many products on top of Eclipse have a much longer lifecycle than SR2 ... what to do after SR2 ?
      • Duration and Cadence: every 2nd year to be LTS (Juno first), every 6th year to be VLTS (aerospace eg Airbus have 75 year projects)
      • Every LTS costs money ... if there is very high interest there may be budget for more VLTS
    • Source Patches to go into LTS git repo
    • Single Stream Goal: Fragmentation due to cherry-picking dimishes value of LTS ... Integration adds value and reduces cost
    • Governance Model: Committee to decide what can go in ... eg bugfixes only, no API changes ...
    • LTS committers appointed by membership organisation ... doesn't give them project commit rights (these still have to be earned)
      • But Project committers also get access to the LTS forge (as well as the Community Forge)

New Topics

Kim: Last year the Architecture of Open Source Applications book was released. This year the editors are working on volume II with a new set of authors and open source projects. They are looking for technical reviewers for these chapters, if you're interested let me know and I can put you in touch with the editors.

General Topics

  • Updates from the Board
  • git @ Eclipse progress
  • Maven @ Eclipse progress
  • AC Backlog

Old Topics

  • bug 324125 architecture diagrams - 2006 version - relationship to e4 ?
  • IP Logs - Martin and Wayne - project woolsey exists and open for community, Wayne hopes get soemthing downloadable by Christmas
    • Allow projects to file bugs which list collections of libraries that are used for testing (and mark these collectively as exemt prereqs)
      • Couldn't distribute those libs or put them in scm, but could have them on the build server

We need to reduce our bug backlog, by actually coming to a common resolution on some. Here are the most recent ones:

  • DaveC would like to discuss New Committer Guidelines; Scrum / Agile techniques
  • bug 288393 - Denis - Bugzilla Best Practices

Action Items

  • Cleaned up old action items, see Architecture Council/Meetings/February 10 2011 for old stuff
  • (old) Martin to add Eclipsecon meeting notes onto the wiki
  • (old) Tim write up an initial wiki page with information for people to standardize on the tracing API
  • Martin revise the AC Wiki to make it easier to find the New Member Process. More links on homepage. More usage of categories.
  • Martin bug 315210 Make the AC mailing list open / moderated
