Review of Action Items

  • Last meeting Architecture Council/Minutes August 14 2008#Action Items
  • Ok green.gif Boris to start Architecture Council/Top Ten Recommendations
  • Ok green.gif Martin to draft an E-Mail to eclipse.org-committers for review, inviting to put EAC on CC of bugs
  • Ok green.gif Martin to send E-Mail to EAC list as a reminder for "Architectural Walkthrough". Will propose this to the public only when we get one more project so sign up (in addition to mylyn) to make the review by putting together material (slideware, ...)
  • MichaelS to draft an E-Mail about the "plugin granularity" idea, searching for people to lead the effort
  • Ok green.gif Bjorn or Anne to add a "year of appointment" to members on the councils page
  • Ok green.gif Martin to propose alternate meeting scheme on the mailing list
  • Everyone to think about time commitments that can be made for "architectural things" at Eclipse (3 hours == 1 hr meeting + 2 hrs E-Mail and mentoring)
  • Everyone to propose new members on the mailing list
  • Ok green.gif Martin to create bugzilla bugs for the ISchedulingRule (bug 246840 and LGPL {bug|246945}} discussions

Administrative

  • Meeting Dates - any additional comments? The vote was to keep 2nd thursday of each month (and I propose moving to tuesday as first choice in case there is a public holiday or other conflict on thursday).
  • Architecture Council/Members and Mentors - is it accurate?
    • What projects should have a mentor? (Every / Incubation / Those who ask / ...?)
    • Who's mentoring Apogee?
    • What to do with the COSMOS and Aperi projects, which seem mentorless after Harm Sluiman quit
    • Can we (auto)generate a list of mentor-less projects?
    • Other wishes for re-assigning mentorship?
  • Dormant Status Proposal:
    • Do the 3 month / 1 year times make sense?
    • Mike needs to sign off changes in membership
  • New Member Proposals:
    • Are we too big a crowd already? New Member Proposals?
    • Some ideas (from E4 mostly): Dave Carver, Tom Schindl, Scott Lewis, Konstantin Kommissarchik, Kevin McGuire, David Orme, Paul Webster, Paul Coltron
  • Google Calendar Bugs and Requests -- does anybody know how to report them?
    • Changing an event, "Dont send" does send notifications
    • Response from to mailing list invitation should track attendance of each member separately
  • Welcome Gunnar Wagenknecht as Technology PMC representative to the Architecture Council

News from the Board (EMO)

  • We have board reps and EMO reps on the council (Mike, Bjorn, Jeff, Ed, zx, Mik and Doug Gaff; Wayne)
  • Would like to have a standing "news from the board" topic, since as mentors we should be top informed
  • Other channels (PlanetEclipse, Blog, Committers / Project-leads mailing list, ...) should work but 1st-hand is better
  • Do information channels work well?

Top Ten Recommendations

  • Architecture Council/Top Ten Recommendations
  • More recommendations?
  • Add links into some code which exposes a recommendation as example?
  • Could easily convert a Recommendation into an article / blog post / ... ("The EAC Series")

Deadlocks, Jobs and Scheduling

  • 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
    • work performed in callbacks - unknown context
    • Job / SchedulingRule intermixed with Resources - cannot extend rules after the fact, need to know who locks what internally
  • What can we do to make the Platform safer for Concurrency?
    • Come up with some items in our Architecture Council/Top Ten 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 resouce-deltas article

LGPL Works-with vs. Requires

bug 246945

How to start Releng?

  • Question from a new project: I am trying to create some update sites and build scripts for TmL and I am having some difficults to find some reference material to working with this. Do you have any idea where I can find a starter material to do that??
    • Bjorn, NickB & Denis Build Workshop 3: Build Hard With A Purpose but is that an answer for now? Current status?
    • Refer people to clone existing projects' releng? Which ones are good?
    • Refer to the PDE Build docs? But that's only half of the story?

Other Ideas for Discussion

  • Mentoring New Projects
    • Experiences? What could be improved?
    • Webpage improvements: more pre-canned content for new projects (like Sourceforge)?
  • 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
