This file should contain all know fatal bugs in the Mariadb and the Maria storage engine for the last source or binary release. Minor bugs, extensions and feature request and bugs found since this release can be find in the MariaDB bugs database at: https://bugs.launchpad.net/maria and in the MySQL bugs databases at: http://bugs.mysql.com/ (category "Maria storage engine"). There shouldn't normally be any bugs that affects normal operations in any MariaDB release. Still, there are always exceptions and edge cases and that's what this file is for. If you have found a bug that is not listed here, please add it to http://bugs.launchpad.net/maria so that we can either fix it for next release or in the worst case add it here for others to know! IMPORTANT: If you have been using the Maria storage engine with MySQL-5.1-Maria-alpha build and upgrading to a newer MariaDB you MUST run maria_chk --recover on all your Maria tables. This is because we made an incompatible change of how transaction id is stored and old transaction id's must be reset! cd mysql-data-directory maria_chk --recover */*.MAI As the Maria storage engine is now in beta we will do our best to not introduce any incompatible changes in the data format for the Maria tables; If this would be ever be needed, we will, if possible, support both the old and the new version to make upgrades as easy as possible. Note that for the MariaDB 5.1 release the Maria storage engine is classified as 'beta'; It should work, but use it with caution. Please report all bugs to https://bugs.launchpad.net/maria so that we can fix them!
