Review of Action Items

Administrative

  • New Members: Linda Chan, Sven Efftinge (new Strategic Member)
  • New Dormant Members - see Architecture Council/Members and Mentors
  • Some Bio's still not filled in: Architecture Council/Members and Mentors - Doug Clarke, Sven Efftinge, Steve Northover, Brett Porter, Mary Ruddy, Michael Scharf, Thomas Watson, David Williams, Mike Wilson, Gary Xue
    • Just click on your red link to create a page -- it can't be simpler!
    • Bjorn (and some others) to become dormant?
  • Projects in need of Mentors
  • AC Admin via the Portal
    • Enter Mentorship data on the Portal - new AC component - will show up on the councils page as well as project homepages
    • bug 256318 - Need a page that lists projects and mentors for further processing (query for projects without mentors)
    • bug 258085 - councils page - hyperlink mentored projects against projects' home pages
    • bug 258096 - Request a "Biography URL" in the Portal
    • bug 255383 - councils page doesn't show company affiliation for PMC reps
    • bug 255385 - councils page doesn't show PMC reps for Modeling, Birt, Stp
    • Should we retire the Architecture Council/Members and Mentors page? - Not entirely, 'cause the "dormant" status cannot be tracked in foundation DB, and mentorship for proposed projects won't show up; but don't want to do double bookkeeping
  • Janet's E-Mail asking PMC's and AC to answer IP/Legal related questions:
    • IPZilla update (Mike) ?
  • AC Website Revamp needed to make the information that's already there more consumable

News from the EMO & Councils

  • Don: StAC meeting at Eclipse World -- outcome?
  • Board Meeting Update, based on Martin's AC update
    • Confidential until the Board Meeting minutes are posted on the Foundation Minutes page - navigated from Eclipse homepage by "About us" > "Foundation" > "Meeting Minutes"

Recent Discussions

  • Oisin says - by the time this call happens, I'll be a mentor on the Faceted Framework project, which is Konstantin's move from WTP. It's a little odd, because he has a lot more experience of working in Eclipse than I do :) Would it be useful in some cases to have a rider on the mentorship requirement for old hands starting with new projects? Maybe reduce the mentor count to one? Discuss.
    • Martin thinks: In my understanding, the idea of mentorship is getting a "second pair of eyes" on some things, as well as to foster communications across PMC / Technology boundaries (by means of the AC). If Kosta is more experienced than yourself, this just means that he won't need you that much to answer questions, and you'll likely not have to monitor his efforts a lot. But it's good to have the cross-project exposure by means of the two-mentor-requirement.
  • Tom: What can be done to streamline project proposals even more ... we could provide Tooling for it. I started writing a little RCP-Application which defines an Ecore-Model of required information and provides a UI to enter the data and produce the Review Document

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
