Review of Last Meeting

New Topics

  • Welcome Pascal Rapicault to the council as Strategic Member representative for Sonatype

Naming conventions for p2 repos

  • Pascal's bug 331385 naming conventions for p2 Repos
    • Need better ways for Eclipse stuff to be consumed - coalesce all repos into a single page
    • Might need more Fields (multiple Repo's per project)
    • Might need data pre-filled for new projects (release, milestone, I-builds, ...)
    • Wayne would like some discussion within a diverse group of people ("working group") - need a definitive suggestion of what the items should look like
    • AI Pascal write a concrete proposal to discuss on the bug

Maven at Eclipse

  • bug 283745 Maven @ Eclipse progress, workinggroup? (Along with bug 288644 naming)
    • Discussion stalled, couple interested parties, but no leadership
    • Wayne feels this is a great opportunity for the AC
    • Pascal feels like there's 2 things being asked: (a) convert Release train repo into a Maven repo;
    • Do a first simple approach and see whether people want more; for Maven Central, there's a lot of Requirements that cannot be filled automatically
    • Some concept disconnect - eg Maven explicit versions for reproducability, vs Eclipse/p2 version ranges
      • --> in Eclipse, a reproducable build is a function of products + repo-list
      • Pascal proposes locking up ranges
    • David W: b3 aggregator can produce hybrid repo, but just on build.e.o and never promoted
      • Some problems were detected, no owner, thus stalled
      • Pascal would only promote pieces (to Central) - each component to check what could be used outside an OSGi container
      • AI David to close the "mechanical bug" (bug 312656)
      • Community wants released stuff easily consumable; get that by manually importing pieces into their own private repos
      • Could we enable the Community of people who import stuff to share their efforts?

News from the EMO

  • News from the Board, EMO and Councils
    • Had some project terminations - DSDP needs some actual mechanics (archival) done
    • STP in the process of terminating
    • Mylyn restructuring progressing very well tough at a very measured pace
    • TPTP intends to archive after Helios Winter SR .. some other project might absorb pieces
    • Trend .. still getting new projects in, healthy project landscape, no concern for now

e4 - current state of affairs

Injection Discussions

  • John A - some interesting e4 discussions about Injection
    • how to handle multiple injection frameworks within the same application, e.g. Google Guice vs Eclipse 4.0
    • who owns the injection, how to avoid frameworks stepping on each other
    • bug 331235
    • bug 330865
    • bug 330866

Eclipse 4.1 status

  • Eclipse 4.1 status
    • Eric Moffat requested bug 330957 community testing and feedback - some results but underwhelming, only few projects on Eclipse 4.1 for now
    • Pascal: Community still unsure about how it fits in the global picture - still an EAR (Early Adopter Release)
    • Boris: Focusing on other Eclipse projects for now because projects need dependencies to work
    • Martin: might be some small things making perception, eg splashscreen, make downloads more easily findable
  • New e4 Work area for generalizing JDT for non-Java VM languages
    • OT/J, AspectJ, Groovy/Eclipse, and bunch of JDT committers

Old Topics

  • bug 324125 architecture diagrams - 2006 version - relationship to e4 ?
  • Build systems requirements - Antoine, Dave C
    • Martin in touch with Nick and Henrik
  • 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 285074 - Dave Carver - Hudsonbuilder and write access to the cvs / svn repo
  • bug 288393 - Denis - Bugzilla Best Practices

Action Items

  • (old) Michael to flesh out the Patterns idea and remind the EAC -- started Architecture Council/Top Ten Recommendations#Design Patterns, backed by EclipseCon tutorial proposals
    • While these show how well-known GoF patterns are applied in Eclipse, Michael's idea was more to find and describe new patterns which are specific to Eclipse
  • (old) Michael to draft an E-Mail about the "plugin granularity" idea, searching for people to lead the effort
  • (old) Tools and Tech PMC's to encourage incubating grandfathered projects find a mentor; mentorless projects due to AC members quitting or falling dormant
  • (old) Martin to add Eclipsecon meeting notes onto the wiki
  • (old) Mik to create initial "architectural walkthrough" material for Mylyn -- 1 wiki page not too large, send link to the mailing list
  • (old) Dave C work with Wayne on a "handbook" for project criteria for becoming a committer (referencing committer guidelines)
  • (old) Dave C come up with a document how to save build resources
  • (old) Dave C to try bugzilla UNCONFIRMED state
  • (old) Wayne to ask Sonatype about Nexus test installation
  • (old) Wayne to try doing a 3.6m2 API Report on Helios m2
  • (old) Martin to file bug for asking Mik hyperlink Wikitext / crowdsourcing Docs handbook on the Architecture Council/Top Ten Project Development Practices page
  • (old) Tom S Athena Common Builder Cookbook
  • (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
  • Antoine / Dave C bug 316642 Requirements Wiki for build systems
