Backport Bug#11756194 to mysql-5.5. slave breaks if
'drop database' fails on master and mismatched tables on
slave.
'DROP TABLE <deleted tables>' was binlogged when
'DROP DATABASE' failed and at least one table was deleted
from the database. The log event would lead slave SQL thread
stop if some of the tables did not exist on slave.
After this patch, It is always binlogged with 'IF EXISTS'
option.
CRASHES ON EVERY START ATTEMPT
Description:
------------
push_warning_printf function is used to print the warning message
to the client. So this function should not invoke while recovering
the server. Moreover current_thd is NULL while starting the server.
Solution:
---------
- Avoiding the warning to be printed while recovery.
This patch already pushed in mysql-5.6.
generate_derived_keys_for_table() did not work correctly in the case where
- it had a potential index on derived table
- however, TABLE::check_tmp_key() would disallow creation of this index
after looking at its future key parts (because of the key parts exceeding
max. index length)
- the code would leave a KEYUSE structure that refers to a non-existant index.
Depending on further optimizer calculations, this could cause a crash.
when restoring auto-inc value in INSERT ... ON DUPLICATE KEY UPDATE, take into account that
1. it may be changed in the UPDATE clause (old code did that)
2. it may be changed in the INSERT clause and then cause a dup key (old code missed that)
