can't store non-activerecord models in session

Fixing that will simply let me move onto the next problem.

There appears to be a few places where there is an assumption that objects in sessions are ActiveRecords.

It is cool that it is not intentional.

My guess -- and it is just a guess -- that from a code perspective there may be a number of unrelated small problems. But, and again this is just a guess: there may be a gaping hole in the test suite.

I have what amounts to an integration test, namely a script that implements the depot application in the Agile Web Development with Rails book, as well as a few other small scenarios. It works on 2.2.2, except for one part that was a regression in that release. It doesn't get very far with 2.3RC0.

It is not currently structured in a way that enables it to be immediately picked up as such, but I'd like to work with somebody to use this to enhance the test suite for Rails. I'd be willing to do the bulk of the work.

Note to self: See 2-2-stable CGIRequest#stale_session_check! for the rescue method catch these types of errors.

I think this is caused because we've pushed out the session saving till outside the dispatch hook.

This means we're marshalling the using 'broken vestigial' constants mentioned in #1339 AR::Base should not be nuking its children, just because it lost interest.
