[Ironruby-core] DataMapper (was Re: Thread Priority)

That's a very good question actually; I know at least one Rails + DataMapper site that will switch to IronRuby if they can get it working (one I used to work on), so I'm personally interested in this as well. :)

Last I checked do_sqlserver wasn't too mature. They don't depend on dbi, so there will need to be a separate abstraction for ADO and <http://ADO.NET> ADO.NET<http://ADO.NET>. I have more faith in do_sqlite3 working, as there is a .NET API for sqlite3 (http://sqlite.phxsoftware.com/), and it would be minimal work to test do_sqlite3 with sqlite-ironruby.

As far as DataMapper itself, it'd be interesting to run DataMapper with it's in-memory database to see if IronRuby at-least run it.

I'll want to look into running datamapper for unit testing sake, but it would be great if someone signed up to work on the sqlserver and sqlite3 support. Ryan, you want to head that up, or at least look for a team?

What's the status of the DataMapper port? I was just trying to use it but couldn't get the gem installed. I'm interested in helping get this working. What next steps are needed?

Thanks,

Quick +1 to vote this patch up.

I've been working on the JRuby support for the DataMapper ORM and
DataObjects(.rb) database connectivity layer. These projects rely in
turn on another project called Extlib, which provides a bunch of
useful extensions (lazy arrays, thread pools, string extensions) for
the other two projects.

I pulled down and built the latest IronRuby and running Extlib's
specs, the lack of Thread#priority appears to be the first blocker in
our support for IR.
