Brian Palmer commented on CASSANDRA-2500:
-----------------------------------------

Jon,

jbellis asked me to take a quick look at this, but I haven't had much luck so 
far getting this to work with DBI 0.4.3, ruby 1.8.7, cassandra 0.8.0 on OS X. 
The short list:

 * ruby syntax error in DBI::DBD::Cass::Database#execute_prepared (missing 
comma)
 * Cass::Driver calls super with VERSION which is "0.0.0", but DBI is expecting 
the DBI API version ("0.4.0"), so an exception is thrown on init
 * initializing a new DBI connection fails due to 
DBI::DBD::Cass::Database#active? not checking if @tconn is nil before calling 
@tconn.current_server
 * DBI::DBD::Cass::Statement#execute references db, which isn't defined, it 
probably means to use @db local var
 * After working around the above errors, I get an exception when running a 
select query like `dbh.execute("select * from users;")` : NoMethodError: 
undefined method `size' for #<CassandraThrift::CqlRow:0x102badf58>

I'm not entirely sure if any of these last four are issues specific to my 
environment, but it seems unlikely that they all are. The require statements in 
Cass.rb definitely need cleaning up as well, but it sounds like that's still an 
open question. Also, I'd suggest changing all those define_method calls in 
Cass.rb to normal method definitions just using def, that's very unidiomatic 
ruby.
