1. Fixes BUG#44030 - Error: (1500) Couldn't read the MAX(ID) autoinc value
from the index (PRIMARY)
2. Disables the innodb-autoinc test for innodb plugin temporarily.
The testcase for this bug has different result file for InnoDB plugin.
Should add the testcase to Innodb suite with a different result file.

branches/5.1: When the InnoDB and MySQL data dictionaries go out of sync, before
the bug fix we would assert on missing autoinc columns. With this fix we allow
MySQL to open the table but set the next autoinc value for the column to the
MAX value. This effectively disables the next value generation. INSERTs will
fail with a generic AUTOINC failure. However, the user should be able to
read/dump the table, set the column values explicitly, use ALTER TABLE to
set the next autoinc value and/or sync the two data dictionaries to resume
normal operations.

Remove the word "Error" from the printout because the mysqltest suite
interprets it as an error and thus the innodb-autoinc test fails.

branches/5.1:
Adjust the failing innodb-autoinc test to conform to the latest behavior
of the MySQL code. The idea and the comment in innodb-autoinc.test come
from Sunny.
The test case rpl_do_grant fails sporadically on PB2 with "Access
denied for user 'create_rout_db'@'localhost' ...". Inspecting the
test case, one may find that if issues a GRANT on the master
connection and immediately after it creates two new connections
(one to the master and one to the slave) using the credentials
set with the GRANT.
Unfortunately, there is no synchronization between master and
slave after the grant and before the connections are
established. This can result in slave not having executed the
GRANT by the time the connection is attempted.
This patch fixes this by deploying a sync_slave_with_master
between the grant and the connections attempt.
The test case creates two temporary tables, then closes the
connection, waits for it to disconnect, then syncs the slave with
the master, checks for remaining opened temporary tables on
slave (which should be 0) and finally drops the used
database (mysqltest).
Unfortunately, sometimes, the test fails with one open table on
the slave. This seems to be caused by the fact that waiting for
the connection to be closed is not sufficient. The test needs to
wait for the DROP event to be logged and only then synchronize
the slave with the master and proceed with the check. This is
caused by the asynchronous nature of the disconnect wrt
binlogging of the DROP temporary table statement.
We fix this by deploying a call to wait_for_binlog_event.inc
on the test case, which makes execution to wait for the DROP
temp tables event before synchronizing master and slave.
Problem: LOGGER::general_log_write() relied on valid "thd" parameter passed
but had inconsistent "if (thd)" check.
Fix: as we always pass a valid "thd" parameter to the method,
redundant check removed.
sql/log.cc:
Fix for bug#47130: misplaced or redundant check for null pointer?
- code clean-up, as we rely on the "thd" parameter in the
LOGGER::general_log_write(), redundant "if (thd)" check removed,
added assert(thd) instead.
The problem is that argument buffer can be used as result buffer
and it leads to argument value change.
The fix is to use 'old buffer' as result buffer only
if first argument is not constant item.

In RBR, There is an inconsistency between slaves and master.
When INSERT statement which includes an auto_increment field is executed,
Store engine of master will check the value of the auto_increment field.
It will generate a sequence number and then replace the value, if its value is NULL or empty.
if the field's value is 0, the store engine will do like encountering the NULL values
unless NO_AUTO_VALUE_ON_ZERO is set into SQL_MODE.
In contrast, if the field's value is 0, Store engine of slave always generates a new sequence number
whether or not NO_AUTO_VALUE_ON_ZERO is set into SQL_MODE.
SQL MODE of slave sql thread is always consistency with master's.
Another variable is related to this bug.
If generateing a sequence number is decided by the values of
table->auto_increment_field_not_null and SQL_MODE(if includes MODE_NO_AUTO_VALUE_ON_ZERO)
The table->auto_increment_is_not_null is FALSE, which causes this bug to appear. ..

Archive engine returns wrong values for average record length
and max data length.
With this fix they're calculated as following:
- max data length is 2 ^ 63 where large files are supported
and INT_MAX32 where this is not supported;
- average record length is data length / records in data file.

Create temporary InnoDB table fails on case insensitive
filesystems, when lower_case_table_names is 2 (e.g. OS X)
and temporary directory path contains upper case letters.
The problem was that tmpdir prefix was converted to lower
case when table was created, but was passed as is when
table was opened.
Fixed by leaving tmpdir prefix part intact.

if it is empty). Without this, a test suite run
aborted on Windows for "embedded".
This fix was applied dusing the build of 5.4.2-beta.
mysql-test/mysql-test-run.pl:
From the code (function "envsubst()"), it is obvious
that any variable which is used in an ".opt" file needs
to be defined.
If the value is wrong, starting the server may fail -
but if the variable is undefined, the whole test suite
will abort.
So variables which are used in an ".opt" file should
always be defined to some value, even if it is blank.
This fix may be overkill, I did not check in detail
whether all these variables are really used in an ".opt"
file - but some are.

All these are upmerges from 5.1 which came too late to be
included when 5.4.2-beta was cloned, so they were applied
during the build phase.
Unresolved reference to 'innodb_system_libs' in "mysql_config"
In 5.4.2, we use InnoDB 1.0.4 which does file IO via separate
threads, opposed to the use of asynchronous IO previously.
So there is no InnoDB call to "aio_read()" which was searched
in "librt", causing a "-lrt" value of "innodb_system_libs",
that whole variable is gone.
This fix was applied in the build of 5.4.2-beta.

There is no "innodb_system_libs" variable any more,

.
Changed resize_key_cache() to not disable the key cache
after the flush phase. Changed queue handling to use
standard functions. Wake all threads waiting on resize_queue.
We can now have read/write threads waiting there (see below).
.
Combined add_to_queue() and the wait loops that were always
following it to the new function wait_on_queue().
Combined release_queue() and the condition that was always
preceding it to the new function release_whole_queue().
.
Added code to flag and respect the exceptional situation
BLOCK_IN_EVICTION.
.
Rewrote the resize branch of find_key_block().
.
Added code to the eviction handling in find_key_block()
to catch more exceptional cases.
.
Changed key_cache_read(), key_cache_insert() and key_cache_write()
so that they lock keycache->cache_lock whenever the key cache is
initialized. Checking for a disabled cache and incrementing and
decrementing the "resize counter" is always done within the lock.
Locking and unlocking as well as counting the "resize counter" is
now done once outside the loop. All three functions can now handle
a NULL return from find_key_block. This happens in the flush phase
of a resize and demands direct file I/O. Care is taken for
secondary requests (PAGE_WAIT_TO_BE_READ) to wait in any case.
Moved block status changes behind the copying of buffer data.
key_cache_insert() does now read the block if the caller did
supply less data than a full cache block.
key_cache_write() does now take care of parallel running flushes
(BLOCK_FOR_UPDATE, BLOCK_IN_FLUSHWRITE).
.
Changed free_block() to un-initialize block variables in the
correct order and respect an exceptional BLOCK_IN_EVICTION state.
.
Changed flushing to take care for parallel running writes.
Changed flushing to avoid freeing blocks in eviction.
Changed flushing to consider that parallel writes can move blocks
from the file_blocks hash to the changed_blocks hash.
Changed flushing to take care for other parallel flushes.
Changed flushing to assure that it ends with everything flushed.
Optimized normal flush at end of statement (FLUSH_KEEP),
but let other flush types be stringent.
.
Added some comments and debugging statements.

The parser rule for expressions in a udf parameter list contains
two hacks:
First, the parser input stream is read verbatim, bypassing
the lexer.
Second, the Item::name field is overwritten. If the argument to a
udf was a field, the field's name as seen by name resolution was
overwritten this way.
If the field name was quoted or escaped, it would appear as e.g. "`field`".
Fixed by not overwriting field names.

This test case uses mysqlbinlog to dump the content of master-bin.000001,
but the content of master-bin.000001 is not that this test needs.
MTR runs a lot of test cases on one server, so when this test starts, the current binlog file
might not be master-bin.000001, or there are other events are written by tests before.
'RESET MASTER' command must be called at the begin, it ensures that binlog of this test
is wrote to master-bin.000001 correctly.
Three other tests have the same problem, They were fixed together.

Postfix.
extra/rpl_tests/rpl_row_sp006.test had changed to fix this bug.
extra/rpl_tests/rpl_row_sp006.test is also referenced by rpl_ndb_sp006,
So rpl_row_sp006.result must be changed too.
The external 'for' loop in remove_dup_with_compare() handled
HA_ERR_RECORD_DELETED by just starting over without advancing
to the next record which caused an infinite loop.
This condition could be triggered on certain data by a SELECT
query containing DISTINCT, GROUP BY and HAVING clauses.
Fixed remove_dup_with_compare() so that we always advance to
the next record when receiving HA_ERR_RECORD_DELETED from
rnd_next().
