Changelog

0.1.5 (May 12th, 2010)

quite a few patches from Eric Wong related to thread-safety, non-blocking I/O and general cleanup ** wrap mysql_real_connect with rb_thread_blocking_region ** release GVL for possibly blocking mysql_* library calls ** [cleanup] quiet down warnings ** [cleanup] make all C symbols static ** add Mysql2::Client#close method ** correctly free the wrapped result in case of EOF ** Fix memory leak from the result wrapper struct itself ** make Mysql2::Client destructor safely non-blocking
bug fixes for ActiveRecord adapter ** added casting for default values since they all come back from Mysql as strings (!?!) ** missing constant was added ** fixed a typo in the show_variable method
switched over sscanf for date/time parsing in C
made some specs a little finer-grained
initial Sequel adapter added
updated query benchmarks to reflect the difference between casting in C and in Ruby

optimization: implemented a local cache for rows that are lazily created in ruby during iteration. The MySQL C result is freed as soon as all the results have been cached
optimization: implemented a local cache for field names so every row reuses the same objects as field names/keys
refactor the Mysql2 connection adapter for ActiveRecord to not extend the Mysql adapter - now being a free-standing connection adapter

added an EventMachine Deferrable API
added an ActiveRecord connection adapter ** should be compatible with 2.3.5 and 3.0 (including Arel)

fix a bug (copy/paste fail) around checking for empty TIME values and returning nil (thanks @marius)
