init 'wc' variable

replaced String->c_ptr() with String->c_ptr_safe()

The warning happens because string argument is not zero ended.
The fix is to add new parameter 'length' to SQL_CRYPT() and
use ptr() instead of c_ptr().

      
The rpl_binlog_corruption test case was inject failures, specifically,
incidents with invalid numbers to see if the replication was failing
gracefully. However, this test was causing the following warning message
in Valgrind: "Conditional jump or move depends on uninitialised value(s)"
      
The patch fixes the problem by correctly initializing the m_inicident 
number.

mysqldump.test is designed to run with concurrent inserts
disabled. It is disabling concurrent inserts at the very
beginning of the test case, and re-enables them at the
bottom of the test. But for some reason (likely incorrect
merge) we enable concurrent inserts in the middle of the test.

The problem is fixed by enabling concurrent inserts only
at the bottom of the test case.

3 problems found with DES_ENCRYPT/DES_DECRYPT :

1. The max length was not calculated properly. Fixed in fix_length_and_dec()
2. DES_ENCRYPT had a side effect of sometimes reallocating and changing 
the value of its argument. Fixed by explicitly pre-allocating the necessary
space to pad the argument with trailing '*' (stars) when calculating the 
DES digest.
3. in DES_ENCRYPT the string buffer for the result value was not 
reallocated to the correct size and only string length was assigned to it. 
Fixed by making sure there's enough space to hold the result.

information schema tables are based on internal tmp tables which are removed
after each statement execution. So HANDLER comands can not be used with
information schema.

        using it.
The crash was due to a null pointer present for select_lex while 
processing the view.
Adding a check while opening the view to see if its a child of a 
merge table fixed this problem.

Streamlined how we increase the size of our test table.
The new method shows run time decreased by ~60%.
This is not a guarantee that we will not see test timeouts (the random failures noted in the bug),
but it should significantly reduce the chances of this occurring.

Remember the acquired record locks per table handle (row_prebuilt_t)
rather than per transaction (trx_t), so that unlock_row should successfully
unlock all non-matching rows in multi-table operations.
This deficiency was found while investigating Bug #39320.

Revert a change to Makefile.am that I committed accidentally in c4574.

The test case was missing "let $slave_sql_errno= 1594;".

fixed message for 'help' command

The problem was that new lock types were being added without a
corresponding description. Since the lock types (enum values)
are used as indices to the description array, the descriptions
could be shifted depending on the lock type. The solution is to
ensure that every lock type has a correspondent description.

            Engine doesn't allow me to.

In case of incompatible changes between old and new table
versions, the mysqlcheck program prints error messages like
this:
  error: Table upgrade required. Please do
         "REPAIR TABLE `table_name`" to fix it!

However, InnoDB doesn't support REPAIR TABLE query, so the
message is confusing.


Error message text has been changed to:

  Table upgrade required. Please do "REPAIR TABLE `table_name`"
  or dump/reload to fix it!"

The current patch

-- Adds the ibmdb2i suite
-- related include(.inc) files
-- tests for Bug#44020 and Bug#44025

mysql_rename_view can not rename view if database is not the same.
The fix is to add new argument 'new_db' to mysql_rename_view() and
allow rename with different databases
(only for ALTER DATABASE ... UPGRADE DATA DIRECTORY NAME).

allow 'rename view' for ALTER ...UPGRADE DATA DIRECTORY NAME command.
it's safe because a view has valid internal db&table names in this case.

On IBM i 5.4, schemas with names that are longer 
than 8 characters and contain digits or an underscore
cannot contain IBMDB2I tables, even though this should
theoritically be possible if all alpha characters
are uppercase.

THe current patch fixes the IBMDB2I engine to
allow digits and the underscore(_) to be used in
schema names longer than 8 characters on IBM i 5.4.

In some circumstances, when a table is created with
the IBMDB2I engine, the CREATE TABLE statement will
return successfully but the table will not exist.

The current patch addresses the above issue and causes
CREATE to fail and report and error to the user.
