Fix regression on pushbuild 1. The cygwin perl is ancient there, and Net::Ping does not have port_number method (port_number was introduced around 2007). The fix is to check if port_number is present. Otherwise, fallback to the slow connect().

Disabling the mysiam_debug.test in embedded mode because of BUG#43733

  Disable the test in embedded mode

This patch adds corrections to the original patch
submitted 2009-04-08 (http://lists.mysql.com/commits/71607):

- fixed that the original patch didn't work because of an
  incorrect condition;
- added a test case.

storage/myisam/ha_myisam.cc:
  Bug#37631 Incorrect key file for table after upgrading from 5.0 to 5.1
  
  Fix the conformance checker to relax checking
  for the correct version of the tables (for tables
  created by mysql server version <= 4.0)

my_error() was invoked in reset_slave()'s with purge_relay_logs()-failing branch
without passing sql_errno to it.

Fixed with setting sql_errno= ER_RELAY_LOG_FAIL in the purge_relay_logs()-failing branch.




sql/sql_repl.cc:
  set sql_errno= ER_RELAY_LOG_FAIL when purge_relay_logs() fails.

This is a "null" merge because the fix is
already in 5.1

Error happens because sp_head::MULTI_RESULTS is not set for SP
which has 'show table status' command.
The fix is to add a SQLCOM_SHOW_TABLE_STATUS case into
sp_get_flags_for_command() func.

per-file comments:
  tests/mysql_client_test.c
the test for bug 37956 isn't relevant anymore.
The query there 'select point(?,?)' doesn't produce an error.

                       
Killing the insert-select statement corrupts the MyISAM table only
when the destination table is empty and when it has indexes. When 
we bulk insert huge data and if the destination table is empty we 
disable the indexes for fast inserts, data is then inserted and 
indexes are re-enabled after bulk_insert operation
                        
Killing the query, aborts the repair table operation during enable
indexes phase leading to table corruption.
                      
We now truncate the table when we detect that enable indexes is
killed for bulk insert query.As we have an empty table before the 
operation, we can fix by truncating the table.

  Testcase for BUG#40827
storage/myisam/ha_myisam.cc:
  Fixed end_bulk_insert() method to truncate the table when we detect enable 
  index operation is killed.

MTR would die as soon as one server terminates
Implemented --wait-all option and associated subroutine

      
A bug in the initialization of key segment information made it point
to the wrong bit, since a bit index was used when its int value
was needed. This lead to misinterpretation of bit columns
read from MyISAM record format when a NULL bit pushed them over
a byte boundary.
Fixed by using the int value of the bit instead.

  Bug#43737: Test result.

key_buffer_size.

The cause of corruption was number overflow when multiplying 
two ulong values, number of used keycache blocks with size
of a single block. The result of multiplication exceeded ulong 
range (4G) and this lead to incorrectly calculated  buffer offset
in the key cache.

The fix is to use size_t for multiplication result.

This patch also fixes pointless cast in safemalloc 
(size of allocated block to uint), that creates lot of false
alarm warnings when using big keycache (> 4GB) in debug mode.

The storage engine was not correctly handling the case in 
which rnd_pos is executed for a handler without a preceding
rnd_next or index read operation. As a result, an unitialized
file handle was sometimes being passed to the QMY_READ API.

The fix clears the rrnAssocHandle at the beginning of each
read operation and then checks to see whether it has been
set to a valid handle value before attempting to use it
in rnd_pos. If rrnAssocHandle has not been set by a previous
read operation, rnd_pos instead falls back to the use of the
currently active handle.

storage/ibmdb2i/ha_ibmdb2i.cc:
  Bug#44337 Select query using index merge fails with MCH3601
  
  - clear the rrnAssocHandle at the beginning of each
    read operation 
  - checks to see whether it has been set to a valid
    handle value before attempting to use it in rnd_pos
