# Changelog
## 0.2.4 (September 17th, 2010)
* a few patches for win32 support from Luis Lavena - thanks man!
* bugfix from Eric Wong to avoid a potential stack overflow during Mysql2::Client#escape
* added the ability to turn internal row caching on/off via the :cache_rows => true/false option
* a couple of small patches for rbx compatibility
* set IndexDefinition#length in AR adapter - Kouhei Yanagita <yanagi@shakenbu.org>
* fix a long-standing data corruption bug - thank you thank you thank you to @joedamato (http://github.com/ice799)
* bugfix from calling mysql_close on a closed/freed connection surfaced by the above fix
## 0.2.3 (August 20th, 2010)
* connection flags can now be passed to the constructor via the :flags key
* switch AR adapter connection over to use FOUND_ROWS option

=== Casting "boolean" columns
You can now tell Mysql2 to cast tinyint(1) fields to boolean values in Ruby with the :cast_booleans option.

== Async
=== Async
Mysql2::Client takes advantage of the MySQL C API's (undocumented) non-blocking function mysql_send_query for *all* queries.
But, in order to take full advantage of it in your Ruby code, you can do:

So if you really need things to stay async, it's best to just monitor the socket with something like EventMachine.
If you need multiple query concurrency take a look at using a connection pool.
=== Row Caching
By default, Mysql2 will cache rows that have been created in Ruby (since this happens lazily).
This is especially helpful since it saves the cost of creating the row in Ruby if you were to iterate over the collection again.
If you only plan on using each row once, then it's much more efficient to disable this behavior by setting the :cache_rows option to false.
This would be helpful if you wanted to iterate over the results in a streaming manner. Meaning the GC would cleanup rows you don't need anymore as you're iterating over the result set.
== ActiveRecord
To use the ActiveRecord driver, all you should need to do is have this gem installed and set the adapter in your database.yml to "mysql2".

Now say you were to iterate over that same collection again, this time yielding 15 rows - the 4 previous rows that had already been turned into ruby hashes would be pulled from an internal cache, then 11 more would be created and stored in that cache.
Once the entire dataset has been converted into ruby objects, Mysql2::Result will free the Mysql C result object as it's no longer needed.
This caching behavior can be disabled by setting the :cache_rows option to false.
As for field values themselves, I'm workin on it - but expect that soon.
