Review of Last Meeting

New Topics

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

  • bug 283745 - Maven - current status, next steps
    • Wayne: Foundation contacted Sonatype about giving GPL'd Nexus version (maybe only commercial provides OBR support)
    • Need to understand better what needs to happen
    • Mylyn provided everything as POM but canceled this again a year ago since there was no consumers
    • Move ahead if there is not too much work
  • bug 285074 - Dave Carver - Hudsonbuilder and write access to the cvs / svn repo
    • Agreed on the bug that this should work
    • John: Platform build now working on Eclipse.org, but blocked on not being able to tag
    • Related: Build machine is too slow if many people start building on build.eclipse.org
    • Martin: Would vservers help?
    • Dave: Stats by Foundation would help
    • Bernd: Not signing every build would help
    • Denis: Possible solutions include more servers / less signing / better scheduling
    • Wayne: Hudson should be able to control what runs in parallel
    • Bernd: What about build2.eclipse.org rather than vservers
      • Denis: Even if on multiple servers, everyone building at the same time is an issue
    • Options for the Community: less signing, different servers, funnel everything through a single build queue
      • DaveC: Incremental checkouts rather than pulling ALL
    • AI DaveC to come up with ideas in a document how to save build resources
      • Better implement improvements directly in Athena rather than having projects do all by themselves
  • bug 288393 - Denis - Bugzilla Best Practices
    • Boris: If there is only ONE assignee for all "triaged" bugs across all of Eclipse, it would be hard to "listen"
    • Want experience reports from a first team implementing the new solution before advertising best practice
    • The new TRIAGED state would be a global change
    • Mik: Mylyn experiments went well, Bugzilla team has been doing something similar
    • If experiments with a TRIAGED state fail, it could be converted into a status_whiteboard or keyword
      • Mik would prefer a project to try it with a keyword
    • Mik: Adding a state is the biggest change we can make... why Mozilla hasn't done this?
      • Mozilla is using UNCONFIRMED as initial state, once triaged they go to NEW (this is a per-project setting)
      • UNCONFIRMED is supported on a per-project basis (as an exception)
      • Advantage: consistent with mozilla, Disadvantage: inconsistent with Eclipse.org
      • AI Dave C volunteers the WTP project to go and try the UNCONFIRMED state (after checking with Dave W)
    • Migration problems with existing NEW bugs?
      • Boris thinks that most bugs in the system today are actually triaged... so less migration effort
      • Denis: Can configure bugmail to receive ONE initial E-mail only as long as a bug is UNCONFIRMED
  • bug 288721 - Sonar / Eclemma - Cedric Brun, Dave Carver
    • Quality statistics for Projects. Dave is a fan of Eclemma
    • Boris: Author of Eclemma is working on a replacement for Emma


Old items

  • The art of project release naming - no bug yet ?!?

Action Items

  • (old) Martin to follow up on Architecture Diagrams idea
  • (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) Mik to create initial "architectural walkthrough" material for Mylyn -- 1 wiki page not too large, send link to the mailing list
  • (old) Tools and Tech PMC's to encourage incubating grandfathered projects find a mentor
  • (old) Cedric, Tom talk to their PMCs about making AC representation official (can be 2 backup reps)
  • (old) Martin to add Eclipsecon meeting notes onto the wiki
  • Dave Carver to blog about bugzilla best practices
  • Wayne to E-mail e.o-committers after that
