NAME

       Wiki::Toolkit::Store::MySQL - MySQL storage backend for Wiki::Toolkit

REQUIRES

       Subclasses Wiki::Toolkit::Store::Database.

SYNOPSIS

       See Wiki::Toolkit::Store::Database

METHODS

       check_and_write_node
             $store->check_and_write_node( node     => $node,
                           checksum => $checksum,
                                           %other_args );

           Locks the node, verifies the checksum, calls "write_node_post_locking" with all supplied arguments,
           unlocks the node. Returns the version of the updated node on successful writing, 0 if checksum
           doesn't match, -1 if the change was not applied, croaks on error.

           Note:  Uses MySQL's user level locking, so any locks are released when the database handle
           disconnects.  Doing it like this because I can't seem to get it to work properly with transactions.
