The test rpl.rpl_failed_drop_tbl_binlog exercises a scenario where
the adaptive hash index is enabled. Try to explicitly enable the
adaptive hash index for this test, and skip the test if it does not
succeed (that is, if the server was not built WITH_INNODB_AHI=ON).
Problem:
=======
DROP TABLE IF EXISTS was killed. The table still exists on
the master but the DDL was still logged.
Analysis:
=========
During the execution of DROP TABLE command "ha_delete_table" call is invoked
to delete the table. If the query is killed at this point, the kill command
is not handled within the code. This results in two issues.
1) The table which is not dropped also gets written into the binary log.
2) The code continues further upon receiving 'KILL QUERY'.
Fix:
===
Upon receiving the KILL command the query should stop its current execution.
Tables which were successfully dropped prior to KILL command should be
included in the binary log.
