In innodb_bug38231.test: replace the fragile sleep 0.2 that depends on timing
with a more robust condition which waits for the TRUNCATE and LOCK commands
to appear in information_schema.processlist. This could also break if there
are other sessions executing the same SQL commands, but there are none during
the execution of the mysql test.

branches/5.1: Fix bug #47621 "MySQL and InnoDB data dictionaries
will become out of sync when renaming columns". MySQL does not
provide new column name information to storage engine to
update the system table. To avoid column name mismatch, we shall
just request a table copy for now.

If the listed columns in the view definition of
the table used in a 'INSERT .. SELECT ..'
statement mismatched, a debug assertion would
trigger in the cache invalidation code
following the failing statement.
Although the find_field_in_view() function
correctly generated ER_BAD_FIELD_ERROR during
setup_fields(), the error failed to propagate
further than handle_select(). This patch fixes
the issue by adding a check for the return
value.

The crash happens because greedy_serach
can not determine best plan due to
wrong inner table dependences. These
dependences affects join table sorting
which performs before greedy_search starting.
In our case table which has real 'no dependences'
should be put on top of the list but it does not
happen as inner tables have no dependences as well.
The fix is to exclude RAND_TABLE_BIT mask from
condition which checks if table dependences
should be updated.

There's no need to copy the value of a field into itself.
While generally harmless (except for some performance penalties)
it may be dangerous when the copy code doesn't expect this.
Fixed by checking if the source field is the same as the destination
field before copying the data.
Note that we must preserve the order of assignment of the null
flags (hence the null_value assignment addition).

myisam tables
Queries following TRUNCATE of partitioned MyISAM table
may crash server if myisam_use_mmap is true.
Internally this is MyISAM bug, but limited to partitioned
tables, because MyISAM doesn't use ::delete_all_rows()
method for TRUNCATE, but goes via table recreate instead.
MyISAM didn't properly fall back to non-mmaped I/O after
mmap() failure. Was not repeatable on linux before, likely
because (quote from man mmap):
SUSv3 specifies that mmap() should fail if length is 0.
However, in kernels before 2.6.12, mmap() succeeded in
this case: no mapping was created and the call returned
addr. Since kernel 2.6.12, mmap() fails with the error
EINVAL for this case.

A failed REVOKE statement is logged with error=0, thus causing
the slave to stop. The slave should not stop as this was an
expected error. Given that the execution failed on the master as
well the error code should be logged so that the slave can replay
the statement, get an error and compare with the master's
execution outcome. If errors match, then slave can proceed with
replication, as the error it got, when replaying the statement,
was expected.
In this particular case, the bug surfaces because the error code
is pushed to the THD diagnostics area after writing the event to
the binary log. Therefore, it would be logged with the THD
diagnostics area clean, hence its error code would not contain
the correct code.
We fix this by moving the error reporting ahead of the call to
the routine that writes the event to the binary log.

The problem is that when we make conditon for
grouped result const part of condition is cut off.
It happens because some parts of 'having' condition
which refer to outer join become const after
make_join_statistics. These parts may be lost
during further having condition transformation
in JOIN::exec. The fix is adding 'having'
condition check for const tables after
make_join_statistics is performed.

DBUG_SYNC_POINT has at least one strong limitation that it's not defined
on all platforms. It has issues cooperating with @@debug.
All in all its functionality is superseded by DEBUG_SYNC facility and
there is no reason to maintain the old less flexible one.
Fixed with adding debug_sync_set_action() function as a facility to set up
a sync-action in the server sources code and re-writing existing simulations
(found 3) to use it.
Couple of tests have been reworked as well.
The patch offers a pattern for setting sync-points in replication threads
where the standard DEBUG_SYNC does not suffice to reach goals.

This has been back-ported from 6.0 as the problems proved to afflict
5.1 as well.
The fix exposed two new bugs. They were reported as follows.
Bug no 52174: Sometimes wrong plan when reading a MAX value
from non-NULL index
Bug no 52173: Reading NULL value from non-NULL index gives wrong
result in embedded server
Both bugs taken together affect a much smaller class of queries than #47762,
so the fix stays for now.
Optimizer erroneously translated LEFT JOIN into INNER JOIN.
It leads to cutting rows with NULL right side. It happens
because Item_row uses not_null_tables() method form the
base(Item) class and does not calculate 'null tables'
properly. The fix is adding calculation of 'not null tables'
to Item_row.

The crash happens because of discrepancy between values of
conts_tables and join->const_table_map(make_join_statisctics).
Calculation of conts_tables used condition with
HA_STATS_RECORDS_IS_EXACT flag check. Calculation of
join->const_table_map does not use this flag check.
In case of MERGE table without union with index
the table does not become const table and
thus join_read_const_table() is not called
for the table. join->const_table_map supposes
this table is const and later in make_join_select
this table is used for making&calculation const
condition. As table record buffer is not populated
it leads to crash.
The fix is adding a check if an engine supports
HA_STATS_RECORDS_IS_EXACT flag before updating
join->const_table_map.

All numeric operators and functions on integer, floating point
and DECIMAL values now throw an 'out of range' error rather
than returning an incorrect value or NULL, when the result is
out of supported range for the corresponding data type.
Some test cases in the test suite had to be updated
accordingly either because the test case itself relied on a
value returned in case of a numeric overflow, or because a
numeric overflow was the root cause of the corresponding bugs.
The latter tests are no longer relevant, since the expressions
used to trigger the corresponding bugs are not valid anymore.
However, such test cases have been adjusted and kept "for the
record".

The class Field_bit_as_char stores the metadata for the
field incorrecly because bytes_in_rec and bit_len are set
to (field_length + 7 ) / 8 and 0 respectively, while
Field_bit has the correct values field_length / 8 and
field_length % 8.
Solved the problem by re-computing the values for the
metadata based on the field_length instead of using the
bytes_in_rec and bit_len variables.
To handle compatibility with old server, a table map
flag was added to indicate that the bit computation is
exact. If the flag is clear, the slave computes the
number of bytes required to store the bit field and
compares that instead, effectively allowing replication
*without conversion* from any field length that require
the same number of bytes to store.

If a single ALTER TABLE contains both DROP INDEX and ADD INDEX using
the same index name (a.k.a. index modification) we need to disable
in-place alter table because we can't ask the storage engine to have
two copies of the index with the same name even temporarily (if we
first do the ADD INDEX and then DROP INDEX) and we can't modify
indexes that are needed by e.g. foreign keys if we first do
DROP INDEX and then ADD INDEX.
Fixed the problem by disabling in-place ALTER TABLE for these cases.
concurrent I_S query
There were two problem:
1) MYSQL_LOCK_IGNORE_FLUSH also ignored name locks
2) there was a race between abort_and_upgrade_locks and
alter_close_tables
(i.e. remove_table_from_cache and
close_data_files_and_morph_locks)
Which allowed the table to be opened with MYSQL_LOCK_IGNORE_FLUSH flag
resulting in renaming a partition that was already in use,
which could cause the table to be unusable.
Solution was to not allow IGNORE_FLUSH to skip waiting for
a named locked table.
And to not release the LOCK_open mutex between the
calls to remove_table_from_cache and
close_data_files_and_morph_locks by merging the functions
abort_and_upgrade_locks and alter_close_tables.

In BUG#49562 we fixed the case where numeric user var events
would not serialize the flag stating whether the value was signed
or unsigned (unsigned_flag). This fixed the case that the slave
would get an overflow while treating the unsigned values as
signed.
In this bug, we find that the unsigned_flag can sometimes change
between the moment that the user value is recorded for binlogging
purposes and the actual binlogging time. Since we take the
unsigned_flag from the runtime variable data, at binlogging time,
and the variable value is comes from the copy taken earlier in
the execution, there may be inconsistency in the
User_var_log_event between the variable value and its
unsigned_flag.
We fix this by also copying the unsigned_flag of the
user_var_entry when its value is copied, for binlogging
purposes. Later, at binlogging time, we use the copied
unsigned_flag and not the one in the runtime user_var_entry
instance.
Non-determinism of the test was caused by lack of setting a proper value to hb period,
actually fixed by BUG@50767.
These fixes aim at possible non-determinism in comparison of received
hb events by master and slave in the circular part of the test.
Even though the HB periods ratio was choosen to be as high as 10, it's still incorrect
to compare number of hb-events basing only a relation between their periods.
Yet another issue is relatively short 60 secs timeout of wait_for_status_var.inc
makes valgrind runs to fail.
Fixed with deploying wait_for_slave_io_to_start afront of calling wait_for_status_var.
The test is made runnable only with MIXED binlog-format as it has close to 1 min
total exec time and there is nothing format specific in it.
mysql-test/suite/rpl/r/rpl_heartbeat_basic.result:
results are changed.
mysql-test/suite/rpl/t/rpl_heartbeat_basic.test:
Reducing the test env to run in only with MIXED mode;
Simplifying logics of the circular setup to verify only
that HB flows both directions.
NULL column for NULL
The optimization to read MIN() and MAX() values from an
index did not properly handle comparisons with NULL
values. Fixed by giving up the particular optimization step
if there are non-NULL safe comparisons with NULL values, as
the result is NULL anyway.
Also, Oracle copyright notice was added to all files.
