Review of Last Meeting

New Topics

  • Problems dialing into German access number
  • Martin: EclipseCon 2013 AC Meeting
    • Sunday all-hands + Breakfast (AI Martin schedule for Tuesday)

How To Contribute Docs

  • Krum bug 397644 How to contribute docs, where to host them and how to publish ?
    • Where to make it visible ?
    • Suggestion to add to the PMI, Wayne commented on the bug
    • Martin suggestion: Add 1 link "AC Recommendations" to the Development Resources

Logging Policy

  • Martin: bug 358968 Policy for configuring Logging systems (like slf4j, commons logging, log4j, logback, ...) in Eclipse
    • Mylyn disables commons logging
    • bug 400027 m2e configures logback as null logger for similar reasons;
    • Handle on EPP level ?
    • Martin: OK with plugins (like Mylyn) disabling logging of downstream components by default;
      • Allow re-enabling logging from the outside eg via System Property
      • Document how to re-enable it (eg via System Property / Eclipse.ini
    • Steffen: Became aware that Microsoft had issues with Mylyn disabling logging by default
    • Request is for a standardized way to enable or disable logging
      • Michael: Common Preference ?
    • If a plugin wants logging and another does not, who should win ? - Cannot assign priorities on plugin level
      • Steffen agrees that logging should be disabled by default on plugin level
    • Recommendation:
      • Steffen: Provide common default implementations for disabling logging ?
        • Those would have to live in Orbit, since logging impls live in Orbit ...

AI Steffen comment on the bug with proposed resolution + idea to provide default implementations for disabling

LTS Updates

  • Martin: LTS updates - see this message, interesting information in the thread
    • John: How would version numbers work in LTS ?
    • Company's own branches vs canonical branch ?
    • Level of testing - how are decisions made what changes flow back into the common branch ?
    • Last Econ's LTS meeting was very introductory and didn't go as deep as we'd like ... maybe schedule a BoF for a follow-up meeting
    • Unsure about current state ... there's now, but are there even build machines
    • Martin: As a project lead, I need to know when LTS adopts changes; since my customers might have an LTS stream and I need to know when my own plugins won't work on LTS due to a version conflict
    • John: People in the Field should know some policies
    • Martin: Maybe at least publish the LTS version numbers publicly (while the bits are private)
    • Publish notes of details, might get potentially interested companies more interested

AI Martin Point Andrew Ross to these questions

e4 API Graduation

  • Any other notices for M6 / EclipseCon ?
    • John: Eclipse Platform 4 is finalizing new e4 API and it's going into M6
      • Adopters please review the API and check if it meets your requirements
      • Meant to be a "usable subset" of the full API; some advanced concepts are not graduating yet and remain provisional
      • Report feedback or gaps; internals you're using that didn't make it into API; there's still some (but limited time!)
      • Most e4 API unchanged compared to Juno - mostly cleanup and docs only, removed / broke / changed things only where absolutely necessary. Therefore, an e4 application that's built against Kepler should typically run on Juno too !

General Topics

  • Eclipse Infrastructure - git, Gerrit, Maven, Hudson, Bugzilla, ...
  • Updates from the Board or the EMO
    • Ed: bug 401236 CLA's and git signed-off-by improvements for automatic tracking
    • IP Committee working on some other things that might life easier for committers, but can't talk about details yet
      • 250-line restriction ... and ways around it like splitting into multiple commits
      • Github: Pulling contributions; external contributions
        • Martin: Fork granularity - what if I want to fork a single plugin only, do I have to fork the whole repo ?
          • Tom: Maintaining the fork is much easier by forking the repo (rebase and keep up-to-date)
          • Use forked repo as a submodule of consumer if desired
  • Ian: Reminder to vote for the Board

Action Items

  • Cleaned up old action items, see Architecture Council/Meetings/February 10 2011 for old stuff
