Review of Last Meeting
- Architecture Council/Meetings/December 10 2009
-
Martin Ask PC to think about an "e4 ready" requirement for next year's train - Martin Ask e4 team to pitch a migration talk at EclipseCon.
- Still open items moved to #Action Items
New Topics
e4 - current state of affairs
- McQ: e4 feels 1 milestone behind where it should be (original goal was self-hosting by Christmas)
- McQ: Look and feel in e4 for the SDK: Susan Franklin created some Markups in bug 293481 please add constructive criticism
- e.g. how much whitespace should be expected etc
- note that an e4 goal is to support multiple looks / feels
- How could AC help / e4 be promoted / early adoption?
- McQ wants selfhosting running by Eclipsecon, thats the right time to start thinking about early adoption
- It would be good to find people who build stuff on "plain e4" rather than the compatibility layer... but currently that is more realistic for standalone rcp apps (RSSOwl?)
- Shape of the model should be pretty stable by now, but rest is in flux... so migrating now would be more about helping e4 than helping apps
- Other candidate: anybody interested in building a web based UI component (hosted in Eclipse but also in a browser) like igoogle home pages... e.g. junit tests running on server show results in something like the junit view rather than plain xml
- Doug S: Ribbon IDE? Toolbar still looks very ugly on Susan's markups
- Legal says: In order to use the Ribbon lnf in an app, one has to sign an agreement with MS which says one is not competing with MS. Pushing that requirement on every consumer of the Platform makes this a non starter in the Platform
target platform docs
- Today, all searchable documentation is for the development host (e.g. o.e.platform.doc.isv)
- When I develop against multiple target platforms, how can I access correct documentation?
- Sample use cases:
- Use Eclipse 3.6m4 development host but work on the R3_5_maintenance brach as target platform
- WTP: Documentation for the server-side target e.g. servlets
- CDT: Documentation for the C runtime I develop against
- RT/Equinox: Documentation for the target I develop against
- Any known solutions? What are people doing today?
- What could be done from an architectural point of view?
- Darin W: UA might be smart enough in terms of its webserver to look for documentation in the target rather than the host
- McQ: Chris G looking at a related IBM usecase... want to have a single large infocenter with docs for multiple products, but have a particular view into that
- Andrew O: For C lib docs, linuxtools has a simple toggle to switch docs
- AI Andrew to follow up with more info for Martin about switching target platform docs in linuxtools
Follow-up:
- bug 76005 filter help by criteria; {{bug|
- bug 306162 hyperlinks pointing to a target that may not be unique
- bug 306164 contributing TOC extensions to an anchor that may not be unique
git at Eclipse - current state of affairs
- is Git for Committers still up to date with bug 280583 complete for the read-only git of all of Eclipse
- could instructions be simplified for the most common use cases:
- Getting source for a plugin I want to change
- Adding a branch for a patch of mine
- Rebasing my branch to a new milestone
- Andrew using the read-only git mirrors and following egit-dev
- AI Andew O file a bug to track adding dummy docs -> bug 299663
- egit seems to be progressing well
- Martin interested in a "git at eclipse for dummies" documentation ... what's the easiest way to get going
- DougS using git for some C projects, unsure about import workflow
Tracing
- TimD: Usage of tracing API (-debug optionsfile) has some drawbacks (restart eclipse, use commandline, how to create optionsfile)
- Every component uses System.out differently
- In e3.4 a new tracing service was added to solve all those issues (dynamically turn options on/off) but not quite finished
- Some things going on in e3.6 to improve tracing API (too much output right now)
- Q: Anybody else interested? Should we have a standard way of doing tracing?
- BrianP: Sounds great!
- As a first step, ask projects to use the Platform tracing API rather than rolling their own (in order to get consistent usage of timestamps etc, and support dynamic on/off of tracing options)
- New stuff, see bug 267683
- AI Tim write up an initial wiki page with information for people to standardize on the tracing API
AC Backlog Discussions
- bug 288721 - Sonar / Eclemma - Cedric Brun, Dave Carver
- Oisin tried it in the context of Maven, likes it
- AI Oisin CC on the bug
- bug 267144 - Re-use of micro components
- Boris: Orbit works very well... but it looks like the problem is not urgent enough
- Kosta proposed the Nexus Project some time ago ... status of this?
- Suggest waiting for somebody to sign up for that work
- AI Martin investigate status of Nexus project
- bug 261408 - Simpler infrastructure for microprojects
- Related to bug 235828 better standard website template, have more web infrastructure auto-generated
- bug 261874 - Provisional API conventions
- Boris suggests talking about that at Eclipsecon over a beer
- See also EclipseCon Tutorial on API Design and Evolution hosted by Boris and Martin (additional presenters welcome)
Items for next meeting
Regular briefing on the status of e4.
Action Items
- (old) Martin to follow up on Architecture Diagrams idea
- (old) Michael to flesh out the Patterns idea and remind the EAC -- started Architecture Council/Top Ten Recommendations#Design Patterns, backed by EclipseCon tutorial proposals
- While these show how well-known GoF patterns are applied in Eclipse, Michael's idea was more to find and describe new patterns which are specific to Eclipse
- (old) Michael to draft an E-Mail about the "plugin granularity" idea, searching for people to lead the effort
- (old) Mik to create initial "architectural walkthrough" material for Mylyn -- 1 wiki page not too large, send link to the mailing list
- (old) Dave C work with Wayne on a "handbook" for project criteria for becoming a committer (referencing committer guidelines)
- (old) Dave C come up with a document how to save build resources
- (old) Dave C to try bugzilla UNCONFIRMED state
- (old) Wayne to ask Sonatype about Nexus test installation
- (old) Wayne to try doing a 3.6m2 API Report on Helios m2
- (old) Wayne to ask EclipseCon PC/Donald if we can get a room for e4 Hack-a-thon (migration, creating plug-ins, etc.)
- (old) Wayne to discuss "e4 ready" marketing campaign with Ian.
- (old) 'Ed to tell Cloudsmith about bug 283745 Maven
- (old) Tools and Tech PMC's to encourage incubating grandfathered projects find a mentor; mentorless projects due to AC members quitting or falling dormant
- (old) Martin to add Eclipsecon meeting notes onto the wiki
- (old) Martin to file bug for asking Mik hyperlink Wikitext / crowdsourcing Docs handbook on the Architecture Council/Top Ten Project Development Practices page
- Andrew to follow up with more info for Martin about switching target platform docs in linuxtools
- Andrew to file bug for better documenting "git at Eclipse for dummiees" and add bug number to AC notes -> bug 299663
- Tim write up an initial wiki page with information for people to standardize on the tracing API
- Martin to investigate status of the Eclipse Nexus Project
