"Remove the alignment option, let valgrind use its default"
Regression introduced in bug#52455. Problem was that the
fixed function did not set the last used partition variable, resulting
in wrong partition used when storing the position of the newly
retrieved row.
Fixed by setting the last used partition in ha_partition::index_read_idx_map.
Race condition may occur: mtr sees the .expect file but it's empty
Fix: wait and try again if file is empty
Addendum: try again if line isn't 'wait' or 'restart'
Also added verbose printout of extra restart options
Added logging of all possible fatal table errors if --log-warnings set to > 1

When dates are represented internally as strings, i.e. when a string constant
is compared to a date value, both values are converted to long integers,
ostensibly for fast comparisons. DATE typed integer values are converted to
DATETIME by multiplying by 1,000,000 (each digit pair representing hour,
minute and second, respectively). But the mechanism did not distuinguish
cached INTEGER values, already in correct format, from newly converted
strings.
Fixed by marking the INTEGER cache as being of DATETIME format.
The test were using external tools not available for embedded.
Fixed by rewriting the test to not rely on external tools like the mysql-client
Also fixed some non portable --exec commands and replaced #p# to #P# to pass
on windows.
rpl_packet got a timeout failure sporadically on PB when stopping
slave. The real reason of this bug is that STOP SLAVE stopped
IO thread first and then stopped SQL thread. It was
possible that IO thread stopped after replicating part of a
transaction which SQL thread was executing. SQL thread would
be hung if the transaction could not be rolled back safely.
After this patch, STOP SLAVE will stop SQL thread first and then stop IO
thread, which guarantees that IO thread will fetch the reset of the
events of the transaction that SQL thread is executing, so that SQL
thread can finish the transaction if it cannot be rolled back safely.
Added below auxiliary files to make the test code neater.

Undoing the patch, it complicates the code but is not the solution
I do not beleive newline mismatch could be the cause of this failure
First, I cannot see how this could be a problem, mtr ignores the newline
when reading the expect file, and the file is written and read on Windows.
Second, if this really was the problem it should have been deterministic:
either the newline is correctly interepreted or it is not.
Problem: the scanner function tested for strings "<![CDATA[" and
"-->" without checking input string boundaries, which led to valgrind's
"Conditional jump or move depends on uninitialised value(s)" error.
Fix: Adding boundary checking.
@ mysql-test/r/xml.result
@ mysql-test/t/xml.test
Adding test

Adding a helper function my_xml_parser_prefix_cmp(),
with input string boundary check.
Committing After latest merge.
Modified check_pct procedure to check return value of wait condition instead
of calling "dirty_pct".
Adding Review comments:
1) Added comment for success variable value
2) Procedure check_pct changed For Adding BOOLEAN input and SELECT QUERY Change
Fixed query plans with loose index scan degraded into index scan.
Analysis:
With MWL#89 subqueries are no longer executed and substituted during
the optimization of the outer query. As a result subquery predicates
that were previously executed and substituted by a constant before
the range optimizer were present as regular subquery predicates during
range optimization. The procedure check_group_min_max_predicates()
had a naive test that ruled out all queries with subqueries in the
WHERE clause. This resulted in worse plans with MWL#89.
Solution:
The solution is to refine the test in check_group_min_max_predicates()
to check if each MIN/MAX argument is referred to by a subquery predicate.
Introduced by the fix for bug#44766.
Problem: it's not correct to use args[0]->str_value as a buffer,
because args[0] may need this buffer for its own purposes.
Fix: adding a new class member tmp_value to use as return value.
@ mysql-test/r/ctype_many.result
@ mysql-test/t/ctype_many.test
Adding tests
@ sql/item_strfunc.cc
Changing code into traditional style:
use "str" as a buffer for the argument and tmp_value for the result value.
@ sql/item_strfunc.h
Adding tmp_value
Problem: when processing a query like:
SELECT '' LIKE '1' ESCAPE COUNT(1);
escape_item->val_str() was never executed and the "escape" class member
stayed initialized, which led to valgrind uninitialized memory error.
Note, a query with some tables in "FROM" clause
returns ER_WRONG_ARGUMENTS in the same situation:
SELECT '' LIKE '1' ESCAPE COUNT(1) FROM t1;
ERROR 1210 (HY000): Incorrect arguments to ESCAPE
Fix: disallowing using aggregate functions in ESCAPE clause,
even if there are no tables used. There is no much use of that anyway.
When mysqldadmin is run with sleep and count options,
it goes into an infinite loop and keeps executing the
specified command.
This happened because the statement, responsible for
decrementing the count value, was missing.
Fixed by adding a statement which will decrement the
count value for each iteration.
client/mysqladmin.cc:
Bug#58221 : mysqladmin --sleep=x --count=x keeps looping
Added a condition to check and decrement the count
value stored in nr_iterations per iteration.
mysql-test/r/mysqladmin.result:
Added a testcase for Bug#58221.
mysql-test/t/mysqladmin.test:
Added a testcase for Bug#58221.
Backport to 5.0.
/*![:version:] Query Code */, where [:version:] is a sequence of 5
digits representing the mysql server version(e.g /*!50200 ... */),
is a special comment that the query in it can be executed on those
servers whose versions are larger than the version appearing in the
comment. It leads to a security issue when slave's version is larger
than master's. A malicious user can improve his privileges on slaves.
Because slave SQL thread is running with SUPER privileges, so it can
execute queries that he/she does not have privileges on master.
This bug is fixed with the logic below:
- To replace '!' with ' ' in the magic comments which are not applied on
master. So they become common comments and will not be applied on slave.
- Example:
'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
will be binlogged as
'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/
IA64 and some other arcitectures use different float rounding mode and
i find no decent way to make it consistent.
So the test changed to be insensitive to this.

Without this patch mysqlhotcopy tests would fail due to not finding the mysqlhotcopy tool in release-like builds.
With this patch the tests would either pass, or fail due to missing Perl modules (see 56817).
Text conflict in mysql-test/mysql-test-run.pl:
- resolved by using logic from 5.5 to find mysqlhotcopy, the intention of this backport. Changed bindir to basedir.
When mysqldump tries to dump information in xml format,
the result does not contain field level comments.
In order to retrieve various informations for a field/column,
mysqldump currently uses 'show fields from <tab>' statement.
The attributes returned by the statement lacks the information
regarding field comments.
Fixed by changing the query to one that probes I_S to retrieve
required field informations, including the field comment.
client/mysqldump.c:
Bug#13618 : mysqldump --xml omits comment on table field.
Replaced the 'show fields' command by a statement that
queries I_S, in order to retrieve information on all the
attributes that 'show fields' returns along-with an additional
column_comment information.

Problem: the auxiliary test files rpl_start_server.inc and rpl_stop_server.inc
write a file that is later read by mtr. The bug was that the file was written
with platform-dependent newline terminators, i.e., \r\n on windows, whereas mtr
only understands \n.
Fix: write the file so that it uses \n on all platforms.
mysql-test/include/rpl_start_server.inc:
Force test to use \n instead of platform-dependent newline terminator.
mysql-test/include/rpl_stop_server.inc:
Force test to use \n instead of platform-dependent newline terminator.

Made sure that the optimal fields are used by TABLE_REF objects
when building index access keys to joined tables.
Fixed a bug in the template function that sorts the elements of
a list using the bubble sort algorithm. The bug caused poor
performance of the function. Also added an optimization that
skips comparison with the most heavy elements that has been
already properly placed in the list.
Made the comparison of the fields belonging to the same Item_equal
more granular: fields belonging to the same table are also ordered
according to some rules.
An assertion failure was triggered for a 6-way join query that used two
join buffers.
The failure happened because every call of JOIN_CACHE::join_matching_records
saved and restored status of all tables that were accessed before the table
join_tab. It must do it only for those of them that follow the last table
using a join buffer.
