Problem: the test failed because errors were found in the error log.
The test case contains suppressions for an old version of the error message,
but the format of the error message has changed without updating the suppression.
Fix: Update the suppression. Also small fixes to improve the test.

of service in prepared statements).

The problem was that server didn't check resulting size of prepared
statement argument which was set using mysql_send_long_data() API.
By calling mysql_send_long_data() several times it was possible
to create overly big string and thus force server to allocate
memory for it. There was no way to limit this allocation.

The solution is to add check for size of result string against
value of max_long_data_size start-up parameter. When intermediate
string exceeds max_long_data_size value an appropriate error message
is emitted.

We can't use existing max_allowed_packet parameter for this purpose
since its value is limited by 1GB and therefore using it as a limit
for data set through mysql_send_long_data() API would have been an
incompatible change. Newly introduced max_long_data_size parameter
gets value from max_allowed_packet parameter unless its value is
specified explicitly. This new parameter is marked as deprecated
and will be eventually replaced by max_allowed_packet parameter.
Value of max_long_data_size parameter can be set only at server
startup.

FAILED DROP DATABASE CAN BREAK STATEMENT BASED REPLICATION

The first phase of DROP DATABASE is to delete the tables in the database.
If deletion of one or more of the tables fail (e.g. due to a FOREIGN KEY
constraint), DROP DATABASE will be aborted. However, some tables could
still have been deleted. The problem was that nothing would be written
to the binary log in this case, so any slaves would not delete these tables.
Therefore the master and the slaves would get out of sync.

This patch fixes the problem by making sure that DROP TABLE is written
to the binary log for the tables that were in fact deleted by the failed
DROP DATABASE statement.

Test case added to binlog.binlog_database.test.

Add a missing DBUG_RETURN function test_if_number().

               INSTALLATION

When starting mysqld as an MS Windows NT service, it crashed 
with "Error 1067: The process terminated unexpectedly".

The problem is that thread local variables are not allocated
and initialized properly when started as a service. When the
server is started as a regular executable, the problem does
not occur.

Analysis showed that this is a regression after the patch for 
Bug#11765237/Bug#11763065.   Before, the thread local storage
was initialized by the call chain:
win_main->my_basic_init->my_thread_basic_global_init->
my_thread_init

When the my_init() structure was changed, this initialization
was moved from win_main to mysqld_main.   When started as
a service win_main is run in a separate thread, which does
not have mysqld_main in its call path, so my_thread_init
is never called for this thread.

Added a call to my_thread_init / my_thread_end in the service
handler function, which solves the problem.

fails when running with ps-protocol).

The problem was that when running in --ps-protocol mode mysqltest.cc
didn't close created prepared statements. So, the plugins could not be
unistalled because there was a prepared statement using them.

A fix is to add a dummy statement that forces mysqltest.cc to close
the last prepared statement (which uses a plugin-defined table).

This patch corrects the problem by fixing the definition and alterations
of the mysql.user table in the .sql files.

Also included are new result files for tests that examine the name 
column of the mysql.user table.

When a RPM test build in a non-release branch is done,
the $MYSQL_BINDIR variable ends in "/usr"
(rather than in "/usr/lib" as in a RPM release build),
this made test "file_contents" fail.

A branch for this case is added to the test.
The test result is unchanged.

Issue:
      SSL_CIPHER set to a specific CIPHER name was not getting picked up by SHOW STATUS Command.

Solution:
      If specific cipher name is specified, avoid overwriting of Cipher List with default Cipher names.

pre-locking list caused by triggers).

The thing is that CREATE TRIGGER / DROP TRIGGER may actually
change pre-locking list of (some) stored routines.

The SP-cache does not detect such changes. Thus if sp_head-instance
is cached in SP-cache, subsequent executions of the cached
sp_head will use inaccurate pre-locking list.

The patch is to invalidate SP-cache on CREATE TRIGGER / DROP TRIGGER.

improved the result file readability.
