"Rows not deleted from innodb partitioned tables if --innodb_autoinc_lock_mode=0"
Due to a previous bugfix which initializes a previously uninitialized
variable, ha_partition::get_auto_increment() may fail to operate
correctly when the storage engine reports that it is only reserving
one value and one or more partitions have a different 'next-value'.
Currently, only affects Innodb's new-style auto-increment code which
reserves larger blocks of values and has less inter-thread contention.

Ensure that innobase_read_and_init_auto performs table autoinc lock when lock_mode = 0
No need for "if" guard around row_unlock_table_autoinc_for_mysql() because
it already performs same check.
Make autoinc_lock_mode variable read-only for duration of running mysqld process.
of statement breaks binlog.
There were two problems discovered by this bug:
1. Default (current) database is not fixed at the creation time.
That leads to wrong output of DATABASE() function.
2. Database attributes (@@collation_database) are not fixed at
the creation time. That leads to wrong resultset.
Binlog breakage and Query Cache wrong output happened because of
the first problem.
The fix is to remember the current database at the PREPARE-time and
set it each time at EXECUTE.
Bug#21422 GRANT/REVOKE possible inside stored function, probably in a trigger
Bug#17244 GRANT gives strange error message when used in a stored function
GRANT/REVOKE statements are non-transactional (no explicit transaction
boundaries) in nature and hence are forbidden inside stored functions and
triggers, but they weren't being effectively forbidden. Furthermore, the
absence of implict commits makes changes made by GRANT/REVOKE statements to
not be rolled back.
The implemented fix is to issue a implicit commit with every GRANT/REVOKE
statement, effectively prohibiting these statements in stored functions
and triggers. The implicit commit also fixes the replication bug, and looks
like being in concert with the behavior of DDL and administrative statements.
Since this is a incompatible change, the following sentence should be
added to the Manual in the very end of the 3rd paragraph, subclause
13.4.3 "Statements That Cause an Implicit Commit": "Beginning with
MySQL 5.0.??, the GRANT and REVOKE statements cause an implicit commit."
Patch contributed by Vladimir Shebordaev
The functions ROW_COUNT/FOUND_ROWS are indeed not safe to be used in
statement based replication.
Added code to declare them as such and switch the statement they're in
to row based logging for mixed mode.
MySQL replicates the time zone only when operations that involve
it are performed. This is controlled by a flag. But this flag
is set only on successful operation.
The flag must be set also when there is an error that involves
a timezone (so the master would replicate the error to the slaves).
This patch adds functionality to row-based replication to ensure the
slave's column sizes are >= to that of the master.
It also includes some refactoring for the code from WL#3228.
This patch corrects a problem found during testing on Solaris. The code
changes how length values are retrieved on big endian machines. The
patch allows the rpl_extraColmaster tests to run on these machines.
