Problem: ======== row_discard_tablespace() updates SYS_TABLES, SYS_INDEXES and reassigns the table identifier in SYSTEM TABLES. These changes cannot be rolled back, and row_discard_tablespace_for_mysql() commits the transaction even when row_discard_tablespace() returned an error. If the reassignment in row_mysql_table_id_reassign() fails in the middle then the committed data dictionary is inconsistent and the table can no longer be loaded from it, while the in-memory table definition stays in the dictionary cache and remains usable. Solution: ========= row_discard_tablespace_for_mysql(): If row_discard_tablespace() failed, flag the table as corrupted and report the data dictionary inconsistency in the error log. dict_table_open_on_name(): Check dict_table_t::space before reading fil_space_t::get_compression_algo() from it.

MariaDB: The innovative open source database
MariaDB was 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 and the MariaDB Corporation. 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 Corporation, the MariaDB Foundation 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:
