losing it's .MYD When OPTIMIZE TABLE is completed it attempts to rename temporary file to original name. This step may fail on windows when a file is opened. As a result data file might be deleted and optimized copy of file (table_name.MYD) remains. This situation is handled properly by my_delete_allow_opened, so use it instead of my_delete when attempting to rename a file on windows. No suitable test case for this bug. mysys/my_redel.c: Attempting to delete an opened file and to immediately create a new one with the same name may result in my_redel failure on windows. It may fail because file is not deleted until it is closed. This situation is handled properly by my_delete_allow_opened, so use it instead of my_delete.
