running Rails AR tests with activerecord-jdbc

[Stephen Bannasch <stephen.bannasch@deanbrook.org>]

Hi Nick,

I'm working on running the rails AR tests in JRuby and would like to 
display the version of both activerecord-jdbc-adapter and the 
database adapter it is using.

Initially I'm trying to get these tests working just using mysql so 
I'd like to get these version numbers:

  activerecord-jdbc-adapter
  activerecord-jdbcmysql-adapter

Which for the gems I've got installed now should be 0.9 for both.

Looking at the code I assumed that once the connection was 
established I could get the version info like this:

  ActiveRecord::ConnectionAdapters::JdbcConnection::Version::VERSION

or perhaps:

   ActiveRecord::ConnectionAdapters::JdbcAdapter::Version::VERSION

But references to either throw a const_missing error.

uninitialized constant 
ActiveRecord::ConnectionAdapters::JdbcAdapter::Version (NameError)
uninitialized constant 
ActiveRecord::ConnectionAdapters::JdbcConnection::Version (NameError)

I've attached my patch to trunk rails (actually just to the 
active_record gem). After applying the patch (and setting up the 
proper db for the tests to run) you can run a specific rails AR test 
like this:

$ jruby -S rake test_jdbcmysql TEST=test/cases/attribute_methods_test.rb

There are three of the AR tests which crash jruby and halt the tests 
so for now I'm running the tests in sections:
