The fix inserts newline and comma characters as appropriate
into the constraint reporting code to match the formatting
required by SHOW CREATE TABLE. Additionally, a erroneously
duplicated copy of check_if_incompatible_data() was removed
from db2i_constraints.cc since the correct version is already
in ha_ibmdb2i.cc.
storage/ibmdb2i/db2i_constraints.cc:
Bug#49521 SHOW CREATE TABLE on IBMDB2I tables has incorrect fk constraint format
- Insert newline and comma characters into the constraint reporting
code to match the formatting required by SHOW CREATE TABLE.
- Remove an erroneous copy of check_if_incompatible_data() from
db2i_constraints.cc.
This fix changes the character set used within the
IBMDB2I handler to hash table names to information
about open tables. Previously, tables with names
that differed only in letter case would hash to the
same data structure. This caused incorrect behavior
or errors when two such tables were in use simultaneously.

The help text for --init-slave=name:
"Command(s) that are executed when a slave connects to this master".
This text indicate that the --init-slave option is set on a master
server, and the master server passes the option's argument to slave
which connects to it. This is wrong. Actually the --init-slave option
just can be set on a slave server, and then the slave server executes
the argument each time the SQL thread starts.
Correct the help text for --init-slave option as following:
"Command(s) that are executed by a slave server each time the SQL thread starts."

SPATIAL and FULLTEXT indexes don't support algorithm

Disabled by creating a special grammar rule for these
in the parser.
Added some encasulation of duplicate parser code.
A few problems were found in the fix for bug 43668:
1) Comparison of the YEAR column with NULL always returned TRUE;
2) Comparison of the YEAR column with constants always returned
unpredictable result;
3) Unnecessary conversion warnings when comparing a non-integer
constant with a NULL value in the YEAR column;
The problems described above have been resolved with an
exception: zero (i.e. invalid) YEAR column value comparison
with 00 or 2000 still fail (it is not a regression and it was
not a regression), so MIN/MAX on YEAR column containing zero
value still fail.
mysql-test/r/type_year.result:
Test case for bug #49480.
mysql-test/t/type_year.test:
Test case for bug #49480.
sql/item_cmpfunc.cc:
- The get_year_value() function has been modified to make its
return value compatible with the get_datetime_value() return
value (i.e. to convert numeric values into the YYYY0000000000
(YYYY-00-00 00:00:00) form.
- The Arg_comparator::set_cmp_func method has been modified to
use the get_year_value function if get_datetime_value() is not
applicable.
From now only 2 cases have a special processing there:
* both comparing items have MYSQL_TYPE_YEAR field type
or
* one item have is MYSQL_TYPE_YEAR and other one is
is_datetime()-compliant.
- New helper function try_year_cmp_func() has been
added for the better code readability to call from
Arg_comparator::set_cmp_func().
- The Arg_comparator::compare_year method has been removed
since get_year_value() is compatible with the old
Arg_comparator::compare_datetime method that doesn't have
problems #1-#3 (see whole patch entry commentary).
sql/item_cmpfunc.h:
- New helper function try_year_cmp_func() has been
added for the better code readability to call from
Arg_comparator::set_cmp_func().
- Unnecessary Arg_comparator::year_as_datetime and
Arg_comparator::compare_year() declarations have been
removed.

Arg_comparator uses Item_cache objects to store constants being compared when
they're need a type conversion. Because this cache wasn't initialized properly
Arg_comparator might produce wrong comparison result.
The Arg_comparator::cache_converted_constant function now initializes cache
prior to usage.

Bug#49489: Uninitialized cache led to a wrong result.
The Arg_comparator::cache_converted_constant function now initializes cache
prior to usage.
This fix has been proposed by Sergey Petrunya and has been contributed
under SCA by sca@askmonty.org.
The cause for this valgrind error is that in the function
add_cond_and_fix() in sql_select.cc an Item_cond_and object is
created. This is marked as fixed but does not have a correct
table_map() attribute. Later, in make_join_select(), if
engine_condition_pushdown is in use, this table map is used and
results in the valgrind error.
The fix is to add a call to update_used_tables() in add_cond_and_fix()
so that the table map is updated correctly.
This patch is tested by multiple existing tests (e.g. the tests
innodb_mysql, innodb, fulltext, compress all produces this valgrind
warning/error without this fix).
sql/sql_select.cc:
In add_cond_and_fix() add a call to update_used_tables() to ensure
the table map is updated.
