How-to verify rails is using mysql gem instead of whatever "-d mysql" provides


#1

How does one verify that a Rails project is using the mysql gem (which
I assume is
faster) instead of whatever “-d mysql” provides ?


#2

Answered my own question, but in case anyone is curious:

  • renaming /usr/lib/libmysqlclient.so.15.0.0 to anything else causes
    script/console to complain like so:

Budgie.find(:all)

!!! The bundled mysql.rb driver has been removed from Rails 2.2.
Please install the mysql gem and try again: gem install mysql.
LoadError: libmysqlclient.so.15: cannot open shared object file: No
such file or directory - /usr/lib/ruby/1.8/i486-linux/mysql.so
from /usr/lib/ruby/1.8/i486-linux/mysql.so
