The InnoDB background DROP TABLE queue is something that we should really remove, but are unable to until we remove dict_operation_lock so that DDL and DML operations can be combined in a single transaction. Because the queue is not persistent, it is not crash-safe. We should in some way ensure that the deferred-dropped tables will be dropped after server restart. The existence of two separate transactions complicates the error handling of CREATE TABLE...SELECT. We should really not break locks in DROP TABLE. Our solution to these problems is to rename the table to a temporary name, and to drop such-named tables on InnoDB startup. Also, the queue will use table IDs instead of names from now on. check-testcase.test: Ignore #sql-ib*.ibd files, because tables may enter the background DROP TABLE queue shortly before the test finishes. innodb.drop_table_background: Test CREATE...SELECT and the creation of tables whose file name starts with #sql-ib. innodb.alter_crash: Adjust the recovery, now that the #sql-ib tables will be dropped on InnoDB startup. row_mysql_drop_garbage_tables(): New function, to drop all #sql-ib tables on InnoDB startup. row_drop_table_for_mysql_in_background(): Remove an unnecessary and misplaced call to log_buffer_flush_to_disk(). (The call should have been after the transaction commit. We do not care about flushing the redo log here, because the table would be dropped again at server startup.) Remove the entry from the list after the table no longer exists. If server shutdown has been initiated, empty the list without actually dropping any tables. They will be dropped again on startup. row_drop_table_for_mysql(): Do not call lock_remove_all_on_table(). Instead, if locks exist, defer the DROP TABLE until they do not exist. If the table name does not start with #sql-ib, rename it to that prefix before adding it to the background DROP TABLE queue.

# ==== Purpose ====
|
|
#
|
|
# This test is executed twice for each test case. Before every
|
|
# testcase it is run with mysqltest in record mode and will thus
|
|
# produce an output file that can be compared to output from after the
|
|
# tescase. In that way, it is possible to check that a testcase does
|
|
# not have any unwanted side affects.

# We want to ensure all slave configuration is restored. But SHOW
|
|
# SLAVE STATUS returns nothing for servers not configured as slaves,
|
|
# and (after BUG#28796 was fixed) there is no way to de-configure a
|
|
# slave. Hence, it's impossible to clean up the replication state at
|
|
# the end. But we want to check that the slave is stopped, there is
|
|
# no error, and a few other invariants. So we issue SHOW SLAVE
|
|
# STATUS, and if it returns no rows we fake the result.
