insert...select Queries following bulk insert into an empty MyISAM table may break it. This was pure MyISAM problem. When bulk insert into an empty table is complete, MyISAM may want to enable indexes via repair by sort. If repair by sort fails (e.g. insufficient buffer), MyISAM failover to repair with key cache, requesting repair of data file. Repair of data file performs data file substitution. This means that current table instance will point to new data file. Other cached table instances are still pointing to an old, deleted data file. This is fixed by not requesting repair of data file during enable indexes. Explicit REPAIR is not affected, since it flushes all table instances. mysql-test/r/myisam.result: A test case for BUG#51307. mysql-test/t/myisam.test: A test case for BUG#51307. storage/myisam/ha_myisam.cc: When enabling indexes do not attempt to repair data file. |
