Re: [Bacula-users] [Bacula-devel] mysql version

Thank you for your prompt reply. I'll try to answer both Kern and
Randy in this message.

To Kern:

    I thought bacula is developed for some specific version of mysql
    and changing it could be very risky.

To Randy:

    There are the following two types of incompatible changes:

        1) "controlled" incompatible changes introduced by the mylql
           software development team. I want to provide two examples
           here:

               a) Some changes in version 4.1.23 are incompatible with
                  the 4.1.22 version of MySQL.

               http://dev.mysql.com/doc/refman/4.1/en/news-4-1-23.html

               b) Some changes in version 4.1.13 are not compatible
                  with 4.1.12

               http://dev.mysql.com/doc/refman/4.1/en/news-4-1-13.html

        2) This case is rare but not unusual and thus it must be taken
           into account in case you need high reliability.

           There   are incompatible changes   created due   to bug
           corrections. Let's assume a feature F of mysql works well
           but it has some bug that manifests in a predictible and
           known manner. Bacula (or another potential user) of F can
           decide to use the feature by learning how to avoid the
           drawbacks introduced by the bug.   In this such case, the
           way bacula uses the feature F is dependent on the bug.
           Thus, correcting the bug may be not a benefit for bacula.
