Review of Last Meeting

New Topics

Updates from the Board

  • What are the criteria for starting a new project at Eclipse ?
    • Existing code and community;
    • But sometimes existing Eclipse committers want to start something new so they don't have code yet
    • Eg Orion was forced to create the code upfront
    • Foundation didn't want projects that lead nowhere ... increase the chances for project to be successful
    • Could go into an update to the Dev process
    • AI Boris open Bugzilla

Hudson coming to Eclipse

  • Pascal: Worries about Hudson coming to Eclipse, potential re-union with Jenkins and desire to not use the Eclipse Development Process
  • Would like to release every week
  • Ed: If they say they don't like the Process they should be more specific
  • zx having some private discussions with the Jenkins guys .. might remain 2 projects though
  • Looks like it's a Jenkins - Hudson thing that we can do little about .. other than reaching out and informing Jenkins what Eclipse is really about

Maven @ Eclipse progress

  • zx: signing and publishing making some progress, will hopefully have some code by next call, for signing and publishing via Maven / Tycho
    • bug 339915 Parent POM - not yet, zx working on a draft to send out .. signing would inherit from Parent
    • bug 288644 name spaces / group ID for Maven artifacts - Dave Carver suggests org.eclipse.jdt etc as group ID, corresponding to projects
    • Other related bugs bug 283745 and bug 337068
    • Convert p2 repo into Maven or build with Tycho? - Dave recommends moving forward (creating guidelines)
    • Pascal: Should eventually discuss whether some artifacts should be promoted to Maven Central
      • Maybe a topic for later... some common usable blocks like jface, emf
      • First step is getting stuff into our own Nexus repo, then publish to Central

Moving to git

  • Brian P: When do projects move over, do they have to move over? How much work is the migration (for a skeleton crew)?
  • Boris: Eclipse SDK thinking about moving to git after Indigo for new Dev Streams (not maintenance)
    • Few teams have experience; running test builds with some bundles from git; but unclear how fast can move
  • zx: BIRT looking to move after Indigo; same for Mylyn (50% in git already); CDT going right after indigo
    • Neil: WTP discussions on PMC level - Dave C volunteers to contribute experience from WTP Incubator
  • zx had discussed with Wayne some Workgroup / Wiki page to aid in migration
    • Initially list of projects who're planning to migrate ... also collect experiences
    • Dave C: There is a migration page already
    • AI zx put together something
    • JohnA: Should also collect some wisdom on how to proceed after migration
      • eg how to work with clones on Github ... contributing back from a clone on Github is problematic since 1-way copy
      • In Theory, github enables clones / contributions very easily but contributing back is very hard
        • Seems to be an architectural problem with how github is set up ... it assumes the master is there
        • Getting the patches is painful, but it's still better than what we had before
      • Pascal: Make github the primary clone? - Not allowed by Bylaws today
      • Gerrit would make things much easier (just push into Gerrit without going through Github)
        • CDT very interested in Gerrit... Denis workin on it
        • egit working on github related tooling for pull requests ... but may take a while
    • Scope of the problem ... maybe it's not that bad after all
      • Dave C topic branches might help
    • CDT preparing some scripts for migration - planning to publish them, will allow others to look at
      • See CDT bug 316208 contains attached scripts (Kudos to James Blackburn)

General Topics

  • bug 336874 Updating to Latest Version of Libs
    • Not much happened since bug was opened
    • RH / Fedora trying to ship one (latest) version of each lib only, in order to get security fixes etc
    • Eg some projects ship old libs even if newer ones are in Orbit like JSch
    • Pascal: A timing problem .. need lib by M6 timeframe latest to get into release train
    • zx thinks about some automated process to make people aware .. in general people are OK upgrading when aware
    • A Registry of "who's using what from Orbit" would be a good thing .. information should be in ipzilla
      • Example: If creating a new IP-Bug to ship a library, should CC projects already shipping that lib
    • Should probably have a phase during the annual release in which 3rd party libs are considered (1st quarter of dev cycle .. jan latest)
      • Mostly just small updates ... few brand new things
  • bug 285074 - Dave Carver - Hudsonbuilder and write access to the cvs / svn repo
    • Just a question of "tag before" or "tag after"
    • OK to go ahead and close it - other more important things going on - don't feel to fight that battle now
  • PDE Visualizer - displays dependencies between bundles - not touched currently

Old Topics

  • Pascal's bug 331385 naming conventions for p2 Repos - no time for this at the moment

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
  • Boris open bug for new project criteria discussion
  • zx start Wiki page for collecting git migration advice and experience
