How to start Releng?

Top Ten Recommendations

Relationship to E4

Concurrency

  • Examples: bug 245573 comment 12 (Dali JPA Tools Deadlock, John CC'd to EAC); bug 246840 discussion about ISchedulingRule (saving project preferences)
  • What is causing issues?
    • work performed during class loading (Activator.start()) - unknown context, can run at unpredictable times
    • work performed in callbacks - unknown context, avoid synchronous callbacks
    • General recommendations: (e.g. avoid synchronous callbacks, avoid in Activator.start(), static initializers or Singleton getters) - a general recommendation could be to avoid performing work at unpredictable times, but that would recommend against lazy initialization in general
    • Does anybody have a well-working, consistent model on top of the current infrastructure?
    • Totally new concurrency mechanism as part of E4 ?
      • David Orme mentions DataBinding Realms and the Threads Considered Harmful blog which references Erlang message-based concurrence
      • Would it help to become more asynchronous under the hood, even if old APIs need to remain for compatibility?
      • Are there any other good known models for concurrency?
    • Better Javadoc ?
      • Example: ISchedulingRule.isConflicting() vs. ISchedulingRule.contains(), and how does it relate to RuleFactory and MultiRule?
    • Articles ? - John referenced the resource-deltas article

Mentoring New Projects

  • We need more Architecture Council members to step up and become project mentors
    • New projects require two mentors (a Good Thing™)
  • How do new projects find/attract a mentor?
    • Mailing list, bugzilla?
    • "Work the crowd"
  • Experiences?
    • What could be improved?
    • Webpage improvements: more pre-canned content for new projects (like Sourceforge)?

Other Ideas for Discussion

  • Mentoring Galileo: What could be improved?
    • Running each project's unittests with full Galileo installed; especially interesting for Performance tests
    • Don't duplicate work done by the Planning Council
    • Integrated bug reporting: Mylyn is providing a bug/error/enhancement reporting facility that will provide a flexible and product-configurable mapping between features, bundles and bug trackers bug 212209 (Example: http://wiki.eclipse.org/images/8/86/Mylyn-Bug-Reporting-Example.jpg ). Do we want this for Galileo?
  • E4 now has bi-weekly calls -- won't discuss E4 on the EAC unless asked / invited
  • Eclipse Pain Points
