MYSQL DB FROM REMOTE 5.0.96 SERVER Problem: mysqldump tool assumes the existence of general_log and slow_log tables in the server. If mysqldump tool executes on a old server where there are no log tables like these, mysqldump tool fails. Analysis: general_log and slow_log tables are added in the ignore-table list as part of bug-26121 fix causes bug-45740 (MYSQLDUMP DOESN'T DUMP GENERAL_LOG AND SLOW_QUERY CAUSES RESTORE PROBLEM). As part of the bug-45740 fix, mysqldump tool adds create table queries for these two tables. But the fix assumes that on all the servers, general_log and slow_log will be there. If the new mysqldump tool is executed against a old server where there are no general_log and slow_log, the mysqldump tool fails with an error that 'there is no general_log table'. Fix: When mysqldump tool is trying to retrieve general_log and slow_log table structures, first the tool should check their existence of these tables in the server instead of trying to dump it blindly.
