Bug#11792: Check all of status code, to catch a crash as a failure
mtr_cases.pl:
Code cleanup for skipped/disabled handling
mtr_process.pl:
In debug mode, report if mysqladmin did not at least
make the server stop listening to the port.
Increased the time waiting for terminating to 20 seconds,
to wait for really slow slave shutdown.
Added call to start_reap_all(), to avoid zombies.
mtr_report.pl:
Removed prototype for unused function mtr_report_test_disabled()
Fixed bug #11479.
The JOIN::reinit method cannot call setup_tables
after the optimization phase since this function
removes some optimization settings for joined
tables. E.g. it resets values of the null_row flag to 0.
subselect.result, subselect.test:
Added a test case for bug #11479.
Added a test case for bug #12392.
item_cmpfunc.cc:
Fixed bug #12392.
Missing handling of rows containing NULL components
when evaluating IN predicates caused a crash.
- Fixed some error condtion when handling dates with 'T'
- Added extra test for bug #11867 (Wrong result with "... WHERE ROW( a, b ) IN ( SELECT DISTINCT a, b WHERE ...)" to show it's not yet fixed
- Safety fixes and cleanups
BUG #11104
Took out the offset-=delimiter_length-1 out of the for loop. It was causing
basically this:
select substring_index('the king of the the hill', 'the', -2) to not work.
The first iteration, offset would be initialised to 24, then strstr would
point at 'the king of the the* hill' ('*'means right before the
character following), returning a offset of 16. The for loop would then
decrement offset by two (3 - 1), to 14, now pointing at
"the king of th*e the hill", _skipping_ past the 'e' in the second to last
'the', and therefore strstr would never have a chance of matching the
second to last 'the', then moving on to the 'the' at the begginning of the
string!
In a nutshell, offset was being decremented by too great a value, preventing
the second to last 'the' from being ever found, hence the result of
'king of the the hill' from the query that is reported in the bug report
func_str.test:
BUG #11104
Added tests to make sure fix addresses issues in original bug report
func_str.result:
BUG #11104
New results for new tests
adding test case
item_strfunc.cc:
Bug#12351
CONCAT with USER()/DATEBASE() and
a column gets strange results.
Mark created Item_str as constant, so CONCAT
cannot reuse it for optimization purposes.
Changed assembler functions to not access global variables or variables in text segement
Added wrapper function in C to longlong2str() to pass _dig_vec_upper as an argument
Added test case for bug #11867.
Fixed results for two existing test cases.
subselect.test:
Added test case for bug #11867.
item_subselect.cc:
Fixed bug #11867.
Added missing code in Item_in_subselect::row_value_transformer
that caused problems for queries with
ROW(elems) IN (SELECT DISTINCT cols FROM ...).
When creating temporary table for UNION, pass TMP_TABLE_FORCE_MYISAM flag to
create_tmp_table if we will be using fulltext function(s) when reading from the
temp. table.
length.
When temporary field created for DATE(LEFT(column,8)) expression, max_length
value is taken from Item_date_typecast, and it is getting it from underlaid
Item_func_left and it's max_length is 8 in given expression. And all this
results in stripping last 2 digits.
To Item_date_typecast class added its own fix_length_and_dec() function
that sets max_length value to 10, which is proper for DATE field.
fixing tests accordingly
item.cc:
Bug #10892 user variables not auto cast for comparisons
When mixing strings with different character sets,
and coercibility is the same, we allow conversion
if one character set is superset for other character set.
