Greetings JRuby-ist!
The final frontier of AR-JDBC 1.3.0 is (finally) here …
The release was originally planned for http://2013.jrubyconf.eu but got
delayed
once again (blame @j2h :). I’d like to take the opportunity to once
again
thank
the JRubyConf people for organizing this excellent event and the JRuby
team
for
giving me a free ticket to attend.
There’s some more in the final than a release after RC deserves, but
hopefully
it’s all for the best, namely two important code updates to note :
-
exec_query('SELECT * FROM users WHERE name = ?', 'SQL', [ [ nil, 'kares' ] ])
would work with AR-JDBC 1.2.x and it still does (only on ActiveRecord
<=
3.2)
but is something inherently wrong since it can not be 100% correct
(without
doing some query analysis) thus we’re deprecating it - if you’re
upgrading to
Rails 4.0 (as well) you will need to rewrite code relying on that
behavior
since it was hard to support due AR’s internals -
Java API received yet another small (binary compatible) refactoring
session due
Oracle’s driver hitting the DB on everygetMetaDatacall, which we
kind
of
called on every SELECT query (just to call a dummy method on it that
returns
a fixed boolean value) - this notably improves Oracle’s exec_query and
related
performance, details at connection.getMetaData() called every time on executing a SELECT query on Oracle · Issue #453 · jruby/activerecord-jdbc-adapter · GitHub (thank you people of
ThoughtWorks)
p.s. This seems Oracle exquisite - other drivers I have checked are
fine.
Full-Log:
Neat release managers would likely shoot another RC but I got tired of
pre-releases,
sorry about that … and do not follow my example unless you’re ready
for
it 
As a reminder this release aims to support Rails 2.3 / 3.x /
4.0 and
is a very recommended update for all AR-JDBC 1.2.x users out there
riding
JRuby.
If you’re planning on migrating from 1.2.x please consult :
(+ feel free to edit the wiki in case you find something that might help
others)
Thanks to all who contributed/supported/tested with us while making this
release!
p.s. Once again, on behalf of keeping AR-JDBC up-to-date with Rails, I
would
like to humbly ask you to step up to the keyboards and keep it fixin’
anytime
you hit an issue (want a feature) with the all new and shiny 1.3
releases
