DURING INNODB RECOVERY
Problem:
=======
The connection 'master' is dropped by mysqltest after
rpl_end.inc. At this point, dropping temporary tables
at the connection 'master' are not synced at slave.
So, the temporary tables replicated from master remain
on slave leading to an inconsistent close of the test.
The following test thus complains about the presence of
temporary table(s) left over from the previous test.
Fix:
===
- Put explicit drop commands in replication tests so
that the temporary tables are dropped at slave as well.
- Added the check for Slave_open_temp_tables in
mtr_check.sql to warn about the remaining temporary
table, if any, at the close of a test.
temp table
This patch introduces two key changes in the replication's behavior.
Firstly, it reverts part of BUG#51894 which puts any update to temporary tables
into the trx-cache. Now, updates to temporary tables are handled according to
the type of their engines as a regular table.
Secondly, an unsafe mixed statement, (i.e. a statement that access transactional
table as well non-transactional or temporary table, and writes to any of them),
are written into the trx-cache in order to minimize errors in the execution when
the statement logging format is in use.
Such changes has a direct impact on which statements are classified as unsafe
statements and thus part of BUG#53259 is reverted.
