Note: I've reset the merge from Gaëtan Denaisse as it brakes some of my usage. I'll review it more carrefully and merge later. I'll also make it compatible with last mysql-utilities
This is a script to keep track of database schema. It helps to check and migrate to a new version of the schema and rollback if necessary.
It uses pt-online-schema-change as backend (http://www.percona.com/doc/percona-toolkit/2.2/pt-online-schema-change.html) and Oracle MySQL utilities (http://dev.mysql.com/doc/workbench/en/mysql-utilities.html).
- mysql-utilities (1.3.3)
- mysql client
- perl-DBI (dependency of pt-online-schema-change)
- perl-DBD-MySQL (dependency of pt-online-schema-chane)
A new type (mysql_schema) and its provider as been added to the project
Currently rollback the addition of foreign keys doesn't work because foreign keys are not copied with mysqldbcopy see http://bugs.mysql.com/bug.php?id=63783
A bug in pt-online-schema-change fails the example with the world database, see https://bugs.launchpad.net/percona-toolkit/+bug/1207186
