In statement-based or mixed-mode replication, use DROP TEMPORARY TABLE
to drop multiple tables causes different errors on master and slave,
when one or more of these tables do not exist. Because when executed
on slave, it would automatically add IF EXISTS to the query to ignore
all ER_BAD_TABLE_ERROR errors.
To fix the problem, do not add IF EXISTS when executing DROP TEMPORARY
TABLE on the slave, and clear the ER_BAD_TABLE_ERROR error after
execution if the query does not expect any errors.
mysql-test/suite/rpl/r/rpl_drop_temp.result:
Updated for the patch of bug#49137.
mysql-test/suite/rpl/t/rpl_drop_temp.test:
Added the test file to verify if DROP MULTI TEMPORARY TABLE
will cause different errors on master and slave, when one or
more of these tables do not exist.
sql/log_event.cc:
Added code to handle above cases which are
removed from sql_parse.cc
sql/sql_parse.cc:
Remove the code to issue the 'Unknown table' error,
if the temporary table does not exist when dropping
it on slave. The above cases decribed in comments
will be handled later in log_event.cc.

The 'rpl_cross_version' fails on mysql-next-mr-bugfixing as following:
mysqltest: In included file "./include/setup_fake_relay_log.inc": At line 80: query
'select './$_fake_filename-fake.000001\n' into dumpfile '$_fake_relay_index'' failed:
1290: The MySQL server is running with the --secure-file-priv option so it cannot execute
this statement.
To fix the problem by removeing the --secure-file-priv option
for adapting the update of the 'setup_fake_relay_log.inc'.
Metadata for geometric fields was not being properly stored by
the slave in its the table definition. This happened because
MYSQL_TYPE_GEOMETRY was not included in the 'switch... case' that
handles field metadata according to the field type. Therefore, it
would default to 0, leading to always have a mismatch between
master's field and slave fields'.
We fix this by deploying the missing 'case MYSQL_TYPE_GEOMETRY:'.
mysql-test/extra/rpl_tests/type_conversions.test:
Added some tests for blob fields and also the particular
case for replicating from/into BLOB into/from GEOMETRY.
sql/field.h:
As requested by Mats, reverted function added by him in
changeset:
http://lists.mysql.com/commits/95313
subselect_single_select_engine::exec()
When a subquery doesn't need to be evaluated because
it returns only aggregate functions and these aggregates
can be calculated from the metadata about the table it
was not updating all the relevant members of the JOIN
structure to reflect that this is a constant query.
This caused problems to the enclosing subquery
('<> SOME' in the test case above) trying to read some
data about the tables.
Fixed by setting const_tables to the number of tables
when the SELECT is optimized away.

When @@session.binlog_format is modified inside a transaction,
it can cause slave to go out of sync.
To fix the problem, make the session variable 'binlog_format'
read-only inside a transaction.

Test result for bug#47863.

is read-only inside a transaction and in sub-statements.

Problem was when calculating the range of partitions for
pruning.
Solution was to get the calculation correct. I also simplified
it a bit for easier understanding.

Added results.

Simplified calculation for partition id for ranges.
Easier to get right and understand.
Added comments.
to string conversions and vice versa"
Initial import of the dtoa.c code and custom wrappers around it
to allow its usage from the server code.
Conversion of FLOAT/DOUBLE values to DECIMAL ones or strings
and vice versa has been significantly reworked. As the new
algoritms are more precise than the older ones, results of such
conversions may not always match those obtained from older
server versions. This in turn may break compatibility for some
applications.
This patch also fixes the following bugs:
- bug #12860 "Difference in zero padding of exponent between
Unix and Windows"
- bug #21497 "DOUBLE truncated to unusable value"
- bug #26788 "mysqld (debug) aborts when inserting specific
numbers into char fields"
- bug #24541 "Data truncated..." on decimal type columns
without any good reason"
Several problems fixed :
1. Non constant expressions in UNION ... ORDER BY were not correctly cleaned up
in st_select_lex_unit::cleanup() causing crashes in EXPLAIN EXTENDED because of
fields quoted by these expressions pointing to the already freed temporary table
used to calculate the UNION.
Fixed by correctly cleaning up expressions of any depth.
2. Subqueries in the order by part of UNION ... ORDER BY ... caused a crash in
EXPLAIN EXTENDED because of a transformation attempt made during EXPLAIN EXTENDED
execution. Fixed by not doing the transformation when in EXPLAIN.
3. Fulltext functions caused crash when in the ORDER BY part of an un-parenthesized
UNION that gets "promoted" to be valid for the whole union, e.g.
SELECT * FROM t1 UNION SELECT * FROM t2 ORDER BY MATCHES (a) AGAINST ('abc' IN BOOLEAN MODE).
This is a case that demonstrates a more general problem of parts of the query being
moved to another level. When doing such transformation late in the optimization run
when most of the flags about the contents of the query are already aggregated it's possible
to "split" the flags so that they correctly reflect the new queries after the transformation.
In specific the ST_SELECT_LEX::ftfunc_list is holding all the free text function for all the
parts of the second SELECT in the UNION and we don't know what part of that is in the ORDER BY
that we're to move to the UNION level and what part is about the other parts of the second SELECT.
Fixed by throwing and error when such statements are about to be processed by adding a check
for the presence of MATCH() inside the ORDER BY clause that's going to get promoted to UNION.
To workaround this new limitation one must parenthesize the UNION SELECTs and provide a real
global ORDER BY for the UNION outside of the parenthesis.
This patch fixes these warnings and some compile time warnings.
On top of that, it also fixes rpl_err_ignoredtable test failure.
This test was failing because the warning suppression text was not
matching the latest text. We fix this by making them match.
mysql-test/suite/rpl/t/rpl_err_ignoredtable.test:
Replaced the suppression text.
sql/rpl_record.cc:
- Fixed some compile time warnings (replaced %d --> %ld and
removed unused mas mask variable.
- Fixed valgrind warnings when using c_ptr(). Replaced with
c_ptr_safe().
sql/rpl_utility.cc:
- Fixed valgrind warnings when using c_ptr(). Replaced with
c_ptr_safe().
At the end of execution top level join execution
we cleanup this join with true argument.
It leads to underlying join cleanup(subquery) with true argument too
and to tmp_table_param->field array cleanup which is required later.
The problem is that Item_func_set_user_var does not set
result_filed which leads to unnecessary repeated excution of subquery
on final stage.
The fix is to set result_field for Item_func_set_user_var.

Bug#49836 reports that the geometry type does not work
with WL#5151 applied.
The GEOMETRY type inherits the blob comparison function,
which read the pack length from the metadata. The GEOMETRY
type does not fill in the metadata with anything sensible,
so it is always zero, meaning that the pack length for the
source type is considered zero, rendering it always "smaller"
than the target type which has pack length 4 (without pointer).
This patch fixes the problem by defining
Field_geom::pack_length_from_metadata() to always use the
same as Field_geom::row_pack_length().
