Eclipse 4.2 vs. 3.8 for Juno
We need to come up with a "proposed plan" for Eclipse Projects and members to evaluate. With their feedback, our proposed plan can become our initial plan, and it, in turn, become our final plan.
During this meeting, I'd like to get feedback on this proposal, to see if it is ready to "publish" for further feedback from the community. I realize that many of you will need more detailed meetings with the projects you represent and/or member companies to see if this plan is reasonable. It will help those discussions if there is a concrete proposal.
(See also notes from previous meeting.)
Proposal
For Juno, Eclipse 4.2 will be the primary workbench, but all (participating) projects will support and maintain a 3.8 based deliverable.
'Primary workbench' means Eclipse 4.2 will be the primary workbench that (participating) projects build against, and test, and will be provided in the common repository, and EPP packages. In all cases, "4.2" means "4.2 plus compatibility layer". That is, no one is expected to split streams, use 4.2 workbench "native" or exploit anything specific to 4.2. Of course, projects can if they want to (within the Assumptions, below) but there is no requirement to exploit 4.2 directly and probably better if low level projects do not.
'Support and maintain a 3.8 based deliverables' means that (participating) projects, at a minimum, agree to continue to provide a deliverable that can be used with 3.8 workbench. In most cases, we hope, this is the exact same deliverable used for the 4.2 based deliverable. This would be true for projects that do not use 4.2 specific API and simply rely on the compatibility layer. But for projects that want to exploit something new in 4.2 workbench ... that is split streams and have one specific to the 4.2 workbench prereq ... then they would still be expected to provide something adopters or upstream projects could use for 3.8-based installs. When there are two separate deliverables, the 3.8-based maintenance version might simply be Indigo SR2, at a minimum. But, even then, there might be cases where versions ranges have to be adjusted, or bugs fixed due to changes in 3.8 (since Indigo SR2 will be built and tested with Eclipse 3.7.2). Those are the minimum assumed deliverables. Naturally, projects may do more if they have desire or reason to, but the goal is to allow adopters an extended "transition" period to 4.x, if needed, where things will still work, in some form, using 3.8 based prereqs. For projects that do have "two deliverables", the 3.8 based one would be available on their own download sites and their own project's software site repositories, not the common repository.
Assumptions
While we want to allow projects to split streams, if they need to do so to exploit some new feature in Eclipse 4.x, we assume no "low level" projects introduce split streams that would require all dependent projects above them to also split streams. This could easily lead to "double work" for many people, which is not practical.
Plan roll-out and point of no return
We need to follow a process of evaluating this proposal, making sure there are no "blockers" that prevent it becoming our final plan.
The first step will be to "publish" this plan for feedback. If, or once, we agree on wording, I'll send note to cross-project list and remind people to talk to their Planning Council representative if they have comments or suggestions on the plan. We'll incorporate feedback received, from projects, or adopters, in our May meeting and then again in our June meeting. At that point, we'll consider our "proposed plan" to be our "initial plan".
To move from "initial plan" to "final plan", we will simply follow our plan and re-evaluate each milestone of Juno, that is for M1, M2, M3, and M4. Naturally, we expect confidence to grow incrementally each milestone, but M4 (in mid-December) will be assumed to be the point of no return. If no issues are found that prohibit this "4.2 is primary" plan, then it will be considered final after M4, mid-December, 2011 (which is the normal time for the "final plans" for our yearly June releases). This cycle differs a little from previous cycles, since it assumes projects and adopters do plenty of early testing with those early milestones (and/or early 3.8 based installs) to make sure it is a valid plan fulfilling their needs. Typically, many projects will be busy with Indigo maintenance during this same period of time, so it does take some commitment to also do the early Juno work if there are any concerns about implementing this plan.
Juno Dates
These are our proposed dates for Juno deliverables. They follow same "pattern" as previous years. Any issues? Discussion? If not, the milestone dates will be forthcoming, also following pattern from previous years.
- Release: June 27, 2012 (fourth Wednesday)
- SR1: September 28, 2012 (fourth Friday)
- SR2: February 22, 2013 (fourth Friday)
These dates were agreed to. It was pointed out that this is what the community would expect, and since one of the oft mentioned strong points of Eclipse is its predictability, we would want a really important reason to deviate
Next Meeting
- May 4, 2011 (our regular "first Wednesday" meeting, at Noon Eastern).
