Review of Last Meeting

• Architecture Council/Meetings/June 9 2011
• Still open items moved to #Action_Items

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?
• Linux Tools: Good feedback from contributors to Linux Tools - patches get stale very quickly, good success with patches commits maintained in external public git repo (setup by contributor)
  • Contributor info got set during the Push, when committer pulls/pushes
  • Docs: Development_Resources/Handling_Git_Contributions
• Gerrit - currently used by egit under special permission, no date yet for other projects to use

Documentation:

• Platform-releng/Git_Workflows from Paul for migrators from CVS
  • Paul's migration scripts that the platform team used are in git://git.eclipse.org/gitroot/e4/org.eclipse.migration.git
  • The Git Parable
  • Pro Git book - especially chapter 3
  • The Pro Git blog
  • EGit/User Guide
  • Git page by Denis (Eclipse infrastructure, Legal stuff, pulling from external repos)

Maven and parent POM

• bug 339915 Parent POM - deployed at eclipse.org; 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
  • The AOSA book is Open Source and available for purchase or free http://www.aosabook.org
• Long-term support meeting yesterday ... minutes ?

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
