Only MyISAM tables locked with LOCK TABLES ... WRITE were affected. A query that is optimized with index_merge doesn't reflect rows inserted within LOCK TABLES. MyISAM doesn't flush a state within LOCK TABLES. index_merge optimization creates a copy of the handler, which thus gets outdated MyISAM state. New handler->clone() method is introduced to fix this problem. For non-MyISAM storage engines it allocates a handler and opens it with ha_open(). For MyISAM it additionally copies MyISAM state pointer to cloned handler. mysql-test/r/index_merge.result: A test case for bug#20256. mysql-test/t/index_merge.test: A test case for bug#20256. sql/ha_myisam.cc: clone method added to handler class. sql/ha_myisam.h: clone method added to handler class. sql/handler.cc: clone method added to handler class. sql/handler.h: clone method added to handler class. sql/opt_range.cc: Use handler clone method. |
