Review of Last Meeting
- Architecture Council/Meetings/April 14 2011
- Still open items moved to #Action_Items
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
