Problem was that for encryption we use temporary scratch area for reading and writing tablespace pages. But if page was not really decrypted the correct updated page was not moved to scratch area that was then written. This can happen e.g. for page 0 as it is newer encrypted even if encryption is enabled and as we write the contents of old page 0 to tablespace it contained naturally incorrect space_id that is then later noted and error message was written. Updated page with correct space_id was lost. If tablespace is encrypted we use additional temporary scratch area where pages are read for decrypting readptr == crypt_io_buffer != io_buffer. Destination for decryption is a buffer pool block block->frame == dst == io_buffer that is updated. Pages that did not require decryption even when tablespace is marked as encrypted are not copied instead block->frame is set to src == readptr. If tablespace was encrypted we copy updated page to writeptr != io_buffer. This fixes above bug. For encryption we again use temporary scratch area writeptr != io_buffer == dst that is then written to the tablespace (1) For normal tables src == dst == writeptr ut_ad(!encrypted && !page_compressed ? src == dst && dst == writeptr + (i * size):1); (2) For page compressed tables src == dst == writeptr ut_ad(page_compressed && !encrypted ? src == dst && dst == writeptr + (i * size):1); (3) For encrypted tables src != dst != writeptr ut_ad(encrypted ? src != dst && dst != writeptr + (i * size):1); |

MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance. MariaDB is brought to you by the MariaDB Foundation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB. MariaDB is developed by many of the original developers of MySQL who now work for the MariadB Foundation and the MariaDB Corporation, and by many people in the community. MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors. A description of the MariaDB project and a manual can be found at: http://mariadb.org/ https://mariadb.com/kb/en/ https://mariadb.com/kb/en/mariadb-vs-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/ As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable. More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode. *************************************************************************** NOTE: MariaDB is specifically available only under version 2 of the GNU General Public License (GPLv2).
