Analysis: ======== As part of BUG#28642318 fix, two new test cases were added. The first test case tests a scenario where two sessions are present, in which the first session has a regular table named 't1' and another session has a temporary table named 't1'. Test executes a DELETE statement on regular table. These statements are captured from binary log and replayed back on new client connection to prove that DELETE statement is applied successfully. Note that the binlog contains only CREATE TEMPORARY TABLE part hence a temporary table gets created in new connection. This replaying logic is implemented by using '--exec $MYSQL' command. If the new connection gets disconnected within the scope of first test case the test passes, i.e the temporary table gets dropped as part thread cleanup. But on slow platforms the connection gets closed at the time of execution of test case 2. When the temporary table is dropped as part thread cleanup a "DROP TEMPORARY TABLE t1" is written into the binary log. In test case two the same sessions continue to exist and and table names are reused to test a new bug scenario. The additional "DROP TEMPORARY TABLE" command drops second test specific tables which results in "Unknown table" error. Fix: ==== Rename the second case specific table to 't2'. Even if the close connection from test case one happens later the drop command with has 'DROP /*!40005 TEMPORARY */ TABLE IF EXISTS `t1`' will not result in an error.
