sfDoctrineMysqlSafeMinifyPlugin

===============================

This plugin is to ease the usage of Doctrine migrations with MySQL database by

adding the ability to roll back on an error. 

Doctrine migrations are designed to roll back to the previous state when an

error occurs but this cannot happen with MySQL (at least InnoDB) because of

implicit commits on structure altering queries. To counter this problem this

plugin uses mysqldump to get a snapshot of your database before the migration

and then in the event of an error or a migration dry run the backup will be

restored. 

Because of the nature of a database backup and a restore, there is the

possibility for dataloss during the process of running a migration, with a

large database this could of course make the process very slow. The primary

usage of this plugin is for in a dev/test environment to ensure migration

classes are accurate.
