Subject Re: [CAMEL-3.0] Start moving forward
Date Thu, 17 Jan 2013 13:47:11 GMT

Thanks for taking the initiative and restarting the process for Camel 
3.0. The good news imho is that we're under no pressure and we can take 
the time to get it right.

I like your proposal of effectively splitting the camel-3.0-roadmap page 
into multiple pages. If I understand correctly you are suggesting the 
- proposals should go on the [ideas] wiki and the discussions on the 
mailing lists would refer to the wiki
- the [ideas] page should only contain items currently under discussion
- accepted ideas should move to one of the [roadmap] pages
- keep separate [roadmap] pages for changes to be implemented in 
[2.x-roadmap], [3.0-roadmap] and [3.x-roadmap]

The goal is to move faster and to avoid votes except in highly 
contentious situations which we hope to avoid. I think that would work. 
I also think that have an open concall on irc (plus maybe other channel) 
at a scheduled time would be great, although hard to accommodate the 
time zones.

I would add the following:
1. The ideas on the [ideas] page should be short, containing just an 
abstract. If it takes more than that the details should go in a separate 
[discuss] thread or another page.
2. Keep [discuss] threads focused on one topic only
3. Use endorsements (e.g. username or initials like [hadrian]) to show 
support for an idea (or [-1 hadrian] for a negative endorsement)
4. Once an idea has enough endorsements (3-5, dunno, need to agree on 
something) and no negative endorsement for at least say 72 hours or 
more, we move it to a [roadmap] page.
5. Have only a limited number of 'editors' to move [ideas] to [roadmap]
6. I am also thinking that each accepted idea on the [roadmap] should 
have a champion (not necessarily to implement/commit the code, but stay 
on top of it)

If no objections within 3 hours I will get to organizing the pages.

In terms of concrete development, Guillaume had a very interesting 
proposal at ACEU in November. We discussed concrete ways of refactoring 
the api and realized that it's very hard to fully explain an idea 
without showing some code and it's even harder to grasp the consequences 
without experimenting a bit with the code. We talked about doing that 
either in a (1) separate, possibly github, repo, (2) on a branch or (3) 
in the sandbox. This would have the advantage of being able to show an 
fast idea without concern for backward compatibility and all. More I 
thought about it, more I liked the approach. Of the three alternatives, 
the one I like the most is (3), I guess.

To anticipate objections (miscommunication will happen no matter how 
hard we'll try) backward compatibility and easy, painless migration are 
major goals for 3.0, I would assume everybody agrees. The ways to get 
there are many though.
