Problem: if multibyte and binary string arguments passed to
RPAD(), LPAD() or INSERT() functions, they might return
wrong results or even lead to a server crash due to missed
character set convertion.
Fix: perform the convertion if necessary.

Removed duplicated code
No mysql-test case. Tested by creating a table, removing a *.frm file and
attempting to create the table again. Code coverage tested by
instrumentation. Tested with Valgrind.
After ALTER TABLE which changed only table's metadata, row-based
binlog sometimes got corrupted since the tablemap was unexpectedly
set to 0 for subsequent updates to the same table.
ALTER TABLE which changed only table's metadata always reset
table_map_id for the table share to 0. Despite the fact that
0 is a valid value for table_map_id, this step caused problems
as it could have created situation in which we had more than
one table share with table_map_id equal 0. If more than one
table with table_map_id are 0 were updated in the same statement,
updates to these different tables were written into the same
rows event. This caused slave server to crash.
This bug happens only on 5.1. It doesn't affect 5.5+.
This patch solves this problem by ensuring that ALTER TABLE
statements which change metadata only never reset table_map_id
to 0. To do this it changes reopen_table() to correctly use
refreshed table_map_id value instead of using the old one/
resetting it.
mysql-test/suite/rpl/r/rpl_alter.result:
Add test for BUG#56226
mysql-test/suite/rpl/t/rpl_alter.test:
Add test for BUG#56226
When slave executes a transaction bigger than slave's max_binlog_cache_size,
slave will crash. It is caused by the assert that server should only roll back
the statement but not the whole transaction if the error ER_TRANS_CACHE_FULL
happens. But slave sql thread always rollbacks the whole transaction when
an error happens.
Ather this patch, we always clear any error set in sql thread(it is different
from the error in 'SHOW SLAVE STATUS') and it is cleared before rolling back
the transaction.
mysql-test/suite/rpl/r/rpl_binlog_max_cache_size.result:
SET binlog_cache_size and max_binlog_cache_size for all test cases.
Add test case for bug#55375.
mysql-test/suite/rpl/t/rpl_binlog_max_cache_size-master.opt:
binlog_cache_size and max_binlog_cache_size can be set in the client connection.
so remove this option file.
mysql-test/suite/rpl/t/rpl_binlog_max_cache_size.test:
SET binlog_cache_size and max_binlog_cache_size for all test cases.
Add test case for bug#55375.
sql/log_event.cc:
Some functions don't return the error code, so it is a wrong error code.
The error should always be set into thd->main_da. So we use
slave_rows_error_report to report the right error.
sql/slave.cc:
exec_relay_log_event() need call cleanup_context() to clear context.
clearup_context() will call end_trans().
Clear thd's error before cleanup_context. It avoid to trigger the assert
which cause this bug.

This is a regression from the fix for bug no 38999. A storage engine capable
of reading only a subset of a table's columns updates corresponding bits in
the read buffer to signal that it has read NULL values for the corresponding
columns. It cannot, and should not, update any other bits. Bug no 38999
occurred because the implementation of UPDATE statements compare the NULL bits
using memcmp, inadvertently comparing bits that were never requested from the
storage engine. The regression was caused by the storage engine trying to
alleviate the situation by writing to all NULL bits, even those that it had no
knowledge of. This has devastating effects for the index merge algorithm,
which relies on all NULL bits, except those explicitly requested, being left
unchanged.
The fix reverts the fix for bug no 38999 in both InnoDB and InnoDB plugin and
changes the server's method of comparing records. For engines that always read
entire rows, we proceed as usual. For engines capable of reading only select
columns, the record buffers are now compared on a column by column basis. An
assertion was also added so that non comparable buffers are never read. Some
relevant copy-pasted code was also consolidated in a new function.
Suprisingly, a Slave_log_event would show up in the binary
log. This event is never used and should not appear in the
logs. As such, when the slave (or the mysqlbinlog tool) reads the
event, it will hit an invalid pointer (reference to the
descriptor event when deserializing the Slave_log_event was
purposodely set to NULL).
The presence of the Slave_log_event denotes a corrupted log, but
we cannot tell how the log got corrupted in the first
place. However, we can make the server cope with such events when
it reads them - in case of log corruption - and fail gracefully.
This patch makes the server/mysqlbinlog to report that it has
found an invalid log event when Slave_log_event is read.
The reason for this was that some bitmap test functions changed the bitmap, which caused problems when the same bitmap was used by multiple threads.
include/my_bitmap.h:
Changed order of elements to get better alignment.
mysys/my_bitmap.c:
Change bitmap test functions to not modify the bitmap.
Fixed compiler errors in test_bitmap
LOAD DATA into partitioned MyISAM table
Problem was that both partitioning and myisam
used the same table_share->mutex for different protections
(auto inc and repair).
Solved by adding a specific mutex for the partitioning
auto_increment.
Also adding destroying the ha_data structure in
free_table_share (which is to be propagated
into 5.5).
This is a 5.1 ONLY patch, already fixed in 5.5+.
The crash happens because original join table is replaced with temporary table
at execution stage and later we attempt to use this temporary table in
select_describe. It might happen that
Item_subselect::update_used_tables() method which sets const_item flag
is not called by some reasons (no where/having conditon in subquery for example).
It prevents JOIN::join_tmp creation and breaks original join.
The fix is to call ::update_used_tables() before ::const_item() check.
