Review of Last Meeting

New Topics

  • Welcome Sebastien Gandon (Talend) - Architect at Talend, not committer yet, new Talend Rep
  • Sebastien: Sopera - change of focus from runtime not really true, Sopera bought by Talen - focusing on runtime now, building a root builder and going to contribute
  • Wayne: bug 358980 retire CVS (in favor of git, starting to use the carrot as a stick .. talking about Dev 21,2012 for CVS to go read-only now)
    • asking AC members to help making that a reality
    • Looking at probably retiring SVN support too (not talked to Subversive yet, but going to deprecate from the New Project Provisioning form)
    • egit learning curve... been cited a lot as reason to not move, but we NEED TO start getting things off webmaster's plate
      • egit will never be the same as CVS
      • egit continues to evolve... provide more input
      • hoping that more good things come out of the pressure on teams to move
    • Kim: For projects that haven't moved yet, make it clear that there IS a cost moving
    • Wayne: Moving foundation-managed resources to git (website), putting together a collection of materials for people to learn
  • Gunnar: git releng and tagging strategies (eclipse-dev discussion)
    • Proper solution / migration path from the Mapfiles ?
    • "Git Releng" about to be moved back from egit into Eclipse Releng (just waited for Eclipse Releng to move to git)
    • John: Orion experience was that the only way to move forward was for the Builder to run the tagging script
      • Mapfiles ONLY for replacing version qualifiers; Mapfiles generated automatically; scripts in Orion releng, and floating around
      • Orion always builds from master .. but few developers; Platform is larger, thus idea of 2 branches
      • Orion doesn't use git flow - single branch rather than 2 branches
        • Platform team want "N-builds" in dev branch for all the tests, then "I-builds" in stable/master branch
      • Do any non-trivial change in a private branch, then merge into master when done
    • Naming .. don't care much
    • git flow has some helper scripts that help enforcing the model (eg require any checkin to master must be in dev first)
    • Andrew: Linuxtools pretty small - checkins just into master, CI does git pull every 6 hours or so. "Stable" release branches for releases (stabilization).
    • Doug: Very similar
  • John: It's common in git to work on multiple branches ... but our CI / automated builds are only set up to build on ONE branch
    • Martin: That's built into Gerrit (tied into Hudson) - but unsure how that would work with multiple git repos
  • bug 358917 naming: Enforce different ID's for plugins and features
    • Tycho made a change to enforce the groupID match the artifactID .. perception that ID's have to be different but that's not true
    • Doug: Just uses different group ID for features and bundles
    • Martin: Branding in About Dlg comes from branding bundle that has the same ID as the feature (but there's workarounds)
    • John: many small addons consist of just a single bundle (and feature)... makes no sense to require different ID's
    • RESOLUTION enforcing different ID's can't be a best practice.
  • John: bug 340067 port SWT to GTK3
    • Anyone's welcome to participate
  • Wayne: Updates from the Board and EMO
    • Working with Nathan re-imagine the development portal eg default website - early stages of implementation right now, going to open bugs
    • Long-term support ... EMO posted a job description, looking for an EMO staff member to do releng
    • Gerrit: Denis actively working on it, keeping updates on bug 283749
  • git and IP logs
    • Updated IP logs to extract contributor information from git (using the "Author" field - Development Resources/Handling Git Contributions)
      • Might lead to some duplication in the IP log in the beginning ..
      • Asking Project leads to review the IP log for correctness
        • git queries are expensive, so results are cached and only an "update" is made when generating again
        • background process runs every couple days to clean up
        • If something is missing, either contact Wayne or wait a couple days.
      • Recommendation to include the bug number in the commit message for linking contribution to bug
      • Still need the bug today (for the legal statement), but may not need to iplog+ ... will be replaced by Gerrit when it's running.
    • What's the easiest way to fix the "Author" info?
      • Tom: Amend Commit is easiest
      • John: egit has a field in the commit comment to enter the Author
      • Tom: For patches there's two formats, one with Author info / the other not.
    • Wayne: Make sure the Author is set, then you get the IP log for free
    • Deletions can now count as contributions too
  • Andrew: EAC get-together at Eclipecon Europe
    • Arrange on the mailinglist

General Topics

  • Updates from the Board
  • git @ Eclipse progress
  • Maven @ Eclipse progress
  • AC Backlog

Old Topics

  • bug 324125 architecture diagrams - 2006 version - relationship to e4 ?
  • 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 288393 - Denis - Bugzilla Best Practices

Action Items

  • Cleaned up old action items, see Architecture Council/Meetings/February 10 2011 for old stuff
  • (old) Martin to add Eclipsecon meeting notes onto the wiki
  • (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
