Summary: Rails 2.0 Query Cache not working
Initial Comment:
Rails 2.0.2, AR-JDBC 0.7.2, JRuby trunk rev 5928: The query cache is not
working.
It turned out that the JdbcAdapter class has a "select_all" method (in
active_record/connection_adapters/jdbc_adapter.rb),
which seems to overwrite/redefine the "select_all" method, which has been
prepared by query_cache.rb.
This results in the "select_all_with_query_cache" not being called.
The "select_all" method is the same as the original one in AR's
database_statement.rb, so I decided to simply
remove the method as a workaround. I've added the following line to my
environment.rb:
::ActiveRecord::ConnectionAdapters::JdbcAdapter.send('remove_method',
'select_all') if RUBY_PLATFORM =~ /java/
Note that query_cache.rb also creates a cached version of the "columns" method.
