Review of Last Meeting

Dani: Planning Council Update on Releasing more Frequently

  • 2 months ago, reached consensus renaming to "Mars.1" and "Mars.2". Thus made it more official to allow adding minor features in Update Releases
  • Consensus for keeping the June release as the "major" one where API breakage is allowed
  • Consensus for 3 additional "update" releases from Neon on: End Sept, Mid Dec, End March
    • Cannot opt-out of the release train on updates (but allowed to not contribute again)
    • Cannot break API on updates
    • Eike: For Release Reviews that coincide with the Release Train Update, there's a different deadline (material ready by RC1 -- EDP not yet updated to mention that)
    • Dani: Will need to add a "Feature Deadline" for Update releases moving forward, such that the IP team can plan ahead


Max: How Update Sites Are Handled in the Release Train

  • JBoss Tools using Docker Tooling; Mirror the Eclipse site
    • Linuxtools and CDT have a p2.inf touchpoint pointing to their update site -- adding the "docker fixes" update site in that case
      • This helps users enabling "bugfix" updates for docker easily; underlying tools change quite rapidly, thus there is a need releasing bugfixes quickly
      • Make it easier for Release Train to work with latest valgrind, docker, ...
    • Workaround; Cut out that touchpoint when mirroring the site (to avoid p2 mirror downloading too much)
    • "Automatic Updates" should by default give something that's rock solid and works
  • Q: What is the best way to deliver "important updates" to users easily?
    • Pointing Release Train to a "nightly" site sounds like a bug.
    • Plus p2 gets very slow when checking too many sites (Eike: Oomph Layer in packages includes cached repo, making it much faster)
    • Max Idea 1: Provide a "Mars Rolling" composite p2 repo which actually just points to project's update sites ?
    • Max Idea 2: Get Updates from Marketplace (at least for "optional features")
    • Kosta: Fundamental problem of the Eclipse Release Train - Other communities use multiple train streams eg "stable", "development"
    • Ian: Streams are great, but what's the default? - Bulk of the users will just download and expect it works
      • Max: Get "Mars" by default; allow people to add one site eg "Mars.Rolling" rather than a long list of sites
      • Alex: Could also be a single checkbox in the installer (make the decision upfront)
    • Martin: What do Users/Consumers say - do they complain about "too hard to get updates" ?
    • Wayne: Adding Marketplace Entries for simrel automatically turned out to be too complex
  • Eike likes the idea of a "Mars.Rolling" stream to allow users "check for updates" on contributing repos
    • BUT projects would need some rules to contribute only "bugfix" repos to that stream
    • Kosta: Proposes a broader discussion around which streams may be needed ... ask user explicitly what stream he wants to be on
    • Doug: How to make that happen...

Summary: - It's a real problem today that users who "check for updates" only get access to the Simrel Stream (which publishes updates infrequently).

  • Direct access to project update sites is unintuitive; how could we make it more intuitive to allow getting "project updates" more easily ?
  • Doug agreed taking this discussion to the Planning Council.
