WORK WITH --START-POSITION
If setting --start-position to start after the FD event, mysqlbinlog
will output an error stating that it has not found an FD event.
However, its not that mysqlbinlog does not find it but rather that it
does not processes it in the regular way (i.e., it does not print it).
Given that one is using --base64-output=DECODE-ROWS then not printing
it is actually fine.
To fix this, we make mysqlbinlog not to complain when it has not
printed the FD event, is outputing in base64, but is decoding the
rows.
The new --secure-file-priv checks dereference any symlinks in the paths and compare the
resolved paths.
Thus the 5.0 test suite must do as the 5.1 and up and avoid using symlinks.
The query was re-written *after* we had tagged it with NON_AGG_FIELD_USED.
Remove the flag before continuing.

The problem was that wrong structure of mysql.event was not detected and
the server continued to use wrongly-structured data.
The fix is to check the structure of mysql.event after opening before
any use. That makes operations with events more strict -- some operations
that might work before throw errors now. That seems to be Ok.
Another side-effect of the patch is that if mysql.event is corrupted,
unrelated DROP DATABASE statements issue an SQL warning about inability
to open mysql.event table.
Add extra codes to wait_until_disconnected.inc that are present in 5.5,
but not in 5.1. The missing codes cause innodb_bug59641 to fail in 5.1 on
Windows PB2 runs. The addition of those codes in 5.5 was done in
luis.soares@sun.com-20090930233215-aup3kxy4j6ltvjfp
The partitioning engine checked the auto_increment column even if it was not to be written,
triggering a DBUG_ASSERT.
Fixed by checking if table->write_set for that column was set.
USING '..' ON WINDOWS
Backport of the fix to 5.0 (to be null-merged to 5.1).
Moved the test into the main test suite.
Made mysql-test-run.pl to not use symlinks for sdtdata as the symlinks
are now properly recognized by secure_file_priv.
Made sure the paths in load_file(), LOAD DATA and SELECT .. INTO OUTFILE
that are checked against secure_file_priv in a correct way similarly to 5.1
by the extended is_secure_file_path() backport before the comparison.
Added an extensive test with all the variants of upper/lower case,
slash/backslash and case sensitivity.
Added few comments to the code.
Partitions can have different ref_length (position data length).
Removed DBUG_ASSERT which crashed debug builds when using
MAX_ROWS on some partitions.
calc_daynr() function returns negative result
if malformed date with zero year and month is used.
Attempt to calculate week day on negative value
leads to crash. The fix is return NULL for
'W', 'a', 'w' specifiers if zero year and month is used.
Additional fix for calc_daynr():
--added assertion that result can not be negative
--return 0 if zero year and month is used

Bug#11764671 57533: UNINITIALISED VALUES IN COPY_AND_CONVERT (SQL_STRING.CC) WITH CERTAIN CHA
When ROUND evaluates decimal result it uses Item::decimal
value as fraction value for the result. In some cases
Item::decimal is greater than real result fraction value
and uninitialised memory of result(decimal) buffer can be
used in further calculations. Issue is introduced by
Bug33143 fix. The fix is to remove erroneous assignment.

The bug was fixed by the patch for bug number BUG 11763109 - 55779: SELECT
DOES NOT WORK PROPERLY IN MYSQL SERVER VERSION "5.1.42 SUSE MYSQL (Exact same
fix as was proposed for this bug.) Since the motivation for the two bug
reports was completely different, however, it still makes sense to push the
test case.
This patch contains only the test case.
Some multibyte sequences could be considered by my_mbcharlen() functions
as multibyte character but more exact my_ismbchar() does not think so.
In such a case this multibyte sequences is pushed into 'stack' buffer which
is too small to accommodate the sequence.
The fix is to allocate stack buffer in
compliance with max character length.

Valgrind warnings were caused by comparing index values to an un-initialized field.

sql/opt_sum.cc:
Add thd to opt_sum_query enabling it to test for errors.
If we have a non-nullable index, we cannot use it to match null values,
since set_null() will be ignored, and we might compare uninitialized data.
sql/sql_select.cc:
Add thd to opt_sum_query, enabling it to test for errors.
sql/sql_select.h:
Add thd to opt_sum_query, enabling it to test for errors.
Fix for --vs-config applied
Find.pm incorrectly tested an unitialized local variable instead
of the global, corrected.
Find.pm is also wrong in 5.5: uses a non-existent global variable. Fix when
merging up.
There are two problems with ANALYSE():
1. Memory leak
it happens because do_select() can overwrite
JOIN::procedure field(with zero value in our case) and
JOIN destructor don't free the memory allocated for
JOIN::procedure. The fix is to save original JOIN::procedure
before do_select() call and restore it after do_select
execution.
2. Wrong result
If ANALYSE() procedure is used for the statement with LIMIT clause
it could retrun empty result set. It happens because of missing
analyse::end_of_records() call. First end_send() function call
returns NESTED_LOOP_QUERY_LIMIT and second call of end_send() with
end_of_records flag enabled does not happen. The fix is to return
NESTED_LOOP_OK from end_send() if procedure is active.

DEFINITION OF ANY ROUTINE.
This follow-up patch removes SHOW PROCEDURE CODE from the test
case as this command is only available on debug versions of the
server and therefore caused the test to fail on release builds.
When we create temporary result table for UNION
incorrect max_length for YEAR field is used and
it leads to incorrect field value and incorrect
result string length as YEAR field value calculation
depends on field length.
The fix is to use underlying item max_length for
Item_sum_hybrid::max_length intialization.

Valgrind warning happens due to early null values check
in Item_func_in::fix_length_and_dec(before item evaluation).
As result null value items with uninitialized values are
placed into array and it leads to valgrind warnings during
value array sorting.
The fix is to check null value after item evaluation, item
is evaluated in in_array::set() method.

DEFINITION OF ANY ROUTINE.
The problem was that having the SELECT privilege any column of the
mysql.proc table by mistake allowed the user to see the definition
of all routines (using SHOW CREATE PROCEDURE/FUNCTION and SHOW
PROCEDURE/FUNCTION CODE).
This patch fixes the problem by making sure that those commands
are only allowed if the user has the SELECT privilege on the
mysql.proc table itself.
Test case added to sp-security.test.
Select from a view with the underlying HAVING clause failed with a
message: "1356: View '...' references invalid table(s) or column(s)
or function(s) or definer/invoker of view lack rights to use them"
The bug is a regression of the fix for bug 11750328 - 40825 (similar
case, but the HAVING cause references an aliased field).
In the old fix for bug 40825 the Item_field::name_length value has
been used in place of the real length of Item_field::name. However,
in some cases Item_field::name_length is not in sync with the
actual name length (TODO: combine name and name_length into a
solid String field).
The Item_ref::print() method has been modified to calculate actual
name length every time.

Minor commentary.
create_schema if auto-generate-sql also set.
mysqlslap uses a schema to run its tests on and later
drops it if auto-generate-sql is used. This can be a
problem, if the schema is an already existing one.
If create-schema is used with auto-generate-sql option,
mysqlslap while performing the cleanup, drops the specified
database.
Fixed by introducing an option --no-drop, which, if used,
will prevent the dropping of schema at the end of the test.
client/client_priv.h:
Bug#11765157 - 58090: mysqlslap drops schema specified in

client/mysqlslap.c:
Bug#11765157 - 58090: mysqlslap drops schema specified in

Introduced an option 'no-drop' to forbid the removal of schema
