13.5.9. Maria Open Bugs

This section contains all known fatal bugs in the Maria storage engine for the last source or binary release. Minor bugs, extensions and feature requests and bugs, found since this release can be found in the MySQL bugs databases at: http://bugs.mysql.com/. When reporting a bug, make sure you select the Maria category for the bug.

Note

You can find additional information in the KNOWN_BUGS.txt file within the Maria repository.

There shouldn't normally be any bugs that affect normal operations in any Maria release. Still, there are always exceptions and edge cases and that is what this section is for.

If you have found a bug that is not listed here, please add it to http://bugs.mysql.com/ so that we can either fix it for next release or in the worst case add it here for others to know! When reporting a bug, make sure you select the Maria category for the bug.

Known bugs that are planned to be fixed before next minor release

  • If the log files are damaged or inconsistent, Maria may fail to start. We should fix that if this happens and mysqld is restarted (thanks to mysqld_safe, instance manager or other script) it should disregard the old logs, start anyway and automatically repair any tables that were found to be crashed on open.

    Temporary fix is to remove maria_log.???????? files from the data directory, restart mysqld and run CHECK TABLE/REPAIR TABLE or mysqlcheck on your Maria tables.

    Warning

    Do not remove the maria_log_control file, as this contains the page size information required for reading Maria log and data files.

Known bugs that are planned to be fixed before Beta

  • If we get a write failure on disk for the log, we should stop all usage of transactional tables and mark all transactional tables that are changed as crashed.

  • Missing features that are planned to be fixed before Beta

  • We will add a maria-recover option to automatically repair any crashed tables on open. (This is needed for non-transactional tables and also in edge cases for transactional tables when the table crashed because of a bug in MySQL or Maria code)

Features planned for future releases

You can find details on additional features and functionality planned for Maria, see MySQL Forge Worklog.
