New Mysql Ruby Bindings
There’s been some recent discussions about the way ruby 1.9 handles encodings and the exceptions people are running into, particularly when running rails.
A lot of the time, the exceptions are caused by database drivers passing back multi-byte strings incorrectly tagged as ASCII-8BIT instead of UTF-8.
The work around was ususally to do something like the monkey patch described here. I’ve used that particular patch in production for a few months and it works fine, but monkey patches make me squirm.
This week I was finally able to replace the patch with an alternative mysql gem that retrieves all strings from the database as utf-8 and marks them correctly.
Brian Mario has released mysql2. The basic API is different to the standard mysql gem, but he’s included an ActiveRecord adapter that acts as a drop-in replacement for the mysql one.
To give mysql2 a go in rails install the gem:
Then update your database.yml:
Make sure you get mysql2 version 0.1.6 or higher, in lower versions the ActiveRecord adaptor behaved slightly differently from the default Mysql one.
Brian is incredibly responsive to bug reports, so if you have any issues make sure you report them on the github project.
