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, but blocked on not being able to tag
  • Related: Build machine is too slow if many people start building on
  • 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 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
    • 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 ... looking for volunteers to test it
    • Advantage: Would work directly in the VM -- better performance; possibly EPL'd
  • Sonar: Effort for setting it up? Any guinea pigs?
  • Dave: Buckminster working on Eclemma integration
  • AI Interested parties look at and comment on the bug

Topics for Next Meeting

  • DaveC would like to discuss New Committer Guidelines; Scrum / Agile techniques
  • Wayne: Project plans are important but in a bad state!
    • Mentors please encourage projects to keep their project plans up to date! (Wayne going to blog about)

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
  • (old) Dave C work with Wayne on a "handbook" for project criteria for becoming a committer (referencing committer guidelines)
  • Dave C come up with a document how to save build resources
  • Dave C to try bugzilla UNCONFIRMED state
