Review of Last Meeting

New Topics

Platform git migration update

Platform UI and Equinox migrated, others to come

  • Granularity : Decided on 1 UNIX usergroup per git repository (CDT: 1 usergroup --> 1 repo; WTP: expect 4-5 repos)
    • Andrew: From consumer's point of view, fewer repos are easier - suggest splitting repos later
    • Platform: Some repos are large (120MB) - but others are larger eg Qt 1.5 Gig
    • Physical permissions - can only get access to a whole repo, cannot restrict per branch or per component
  • Paul Webster wrote a series of shellscripts - things that those scripts had to change:
    • Precondition CVS Repos, since branches are not done on all bundles but only some (this was not needed for CDT)
    • Verify the repo after migration (took 48 hours because there was so much history)
    • Moved checked-in binaries that change frequently into external p2 repos, to avoid re-distributing binaries to all client repos
  • Automated builds: Added egit fetch factory to automated builds... mixed mode now, some bundles fetch from CVS, others from git

Other projects that migrated successfully:

  • CDT
  • Mylyn: Converted some CDT-Repo which had lots of tags no longer relevant
  • Used to have 1 build across all of mylyn, now have 7 repositories (1 per subproject) - can do more fine-grained builds now

Other questions:

  • Doug S: Github updates - how often?
  • Linuxtools: Good feedback from contributors to Linuxtools - patches get stale very quickly, good success with patches maintained in external public git repo (setup by contributor)
    • Contributor info got set during the Push, when committer pulls/pushes
    • Docs: "Handling git contributions" under development resources linked off the main page from Denis
  • Gerrit - currently used by egit under special permission, no date yet for other projects to use


  • Platform-releng/Git_Workflows

Maven and parent POM

  • bug 339915 Parent POM - deployed at; zx / Minerva not quite ready yet
    • Sample not yet updated ... could use XSL tooling as sample
    • Need couple patches for signing plugin
    • Mirroring - Proxy for external dependencies; parent POM considered complete with mirror stuff in place
    • Docs: Maven Wiki; use the cross-project or dash-dev mailing list if issues, or open a project against Dash/Maven (or ping Dave C on G+)
    • CDT currently using Tycho without parent POM
  • Runtime wants to push to maven central - ping on dash-dev for current status

General Topics

  • Kim - Took part on "Architecture of Open Source" Webinar based on the book she contributed a chapter to
  • Long-term support meeting yesterday ... minutes ?
  • Updates from the Board
  • Maven @ Eclipse progress

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
