Detailed revision comments: r6770 | marko | 2010-03-03 12:52:55 +0200 (Wed, 03 Mar 2010) | 12 lines branches/zip: Disallow duplicate index name when creating an index. This should fix Mantis Issue #461. innodb.test, innodb.result, innodb-index.test, innodb-index.result: Adjust the test result and mention that the introduced restriction has been reported as MySQL Bug #51451. innobase_check_index_keys(): Add a parameter for the InnoDB table and check that no duplicate index name is added. Report errors by my_error() instead of sql_print_error(). rb://260 approved by Sunny Bains
