I'm afraid that we're rolling over a cliff here. I'd like to have a discussion and resolution on the future of the JPA sandbox work, and IMHO putting it into a branch just defers the real decision that we need to make.
Yes, I agree. We need a proposal for getting JPA into Roller.
There are advantages and disadvantages with using JPA instead of Hibernate native APIs, and we need to resolve whether Roller will support a single back end or multiple back ends. I think there are three end results: 1. Stay the course. JPA continues as a second class citizen, remains in the sandbox, and might not work, subject to feature development in the main line. "Someone" will have to come along after a checkin to make sure that the sandbox code continues to work. 2. Switch out Hibernate API and use JPA API as the one API that is supported by Roller. Note that since Hibernate has a JPA implementation, current users of Roller could continue to use Hibernate but with a different API. 3. Support both JPA and Hibernate native APIs in Roller. New feature development would have to test in both JPA and Hibernate modes before checking in. When I started working on this project, I anticipated outcome 3. I'm used to implementing and using pluggable back ends and this applies equally to hardware platforms, Java VMs, persistence APIs, and databases. It was a bit of a surprise to me that this was not the expectation of the rest of the team, but it was rather late in the cycle when I discovered this would be an issue.
I've had some experience supporting multiple back-end implementations. It is no fun at all and a distraction from what Roller really needs which is better UI, easier installation and cool new features.
I understand that in the early stages of the project, there was some skepticism in the team that the JPA API would be suitable for production. I would say that we should be past discussion on this point. We're down to fine points in the implementation.
Yes. I agree. We need to have that discussion now and I'm going to kick it off by introducing a proposal for Roller 4.0 with JPA today. - Dave
