In case of low memory sort buffer QUICK_INDEX_MERGE_SELECT creates temporary file where is stores row ids which meet QUICK_SELECT ranges except of clustered pk range, clustered range is processed separately. In init_read_record we check if temporary file is used and choose appropriate record access method. It does not take into account that temporary file contains partial result in case of QUICK_INDEX_MERGE_SELECT with clustered pk range. The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT with clustered pk range is used. mysql-test/suite/innodb/r/innodb_mysql.result: test case mysql-test/suite/innodb/t/innodb_mysql.test: test case mysql-test/suite/innodb_plugin/r/innodb_mysql.result: test case mysql-test/suite/innodb_plugin/t/innodb_mysql.test: test case sql/opt_range.h: added new method sql/records.cc: The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT with clustered pk range is used.

Use __builtin_stpcpy only if the system supports stpcpy. This is necessary as in some cases a call to stpcpy will be emitted if the built-in can not optimized. include/m_string.h: The expansion of stpcpy (in glibc) causes warnings if the return value of strmov is not being used. Since stpcpy is a GNU extension and the expansion ends up using a built-in provided by GCC, use the compiler provided built-in directly when possible. Nonetheless, the C library must have stpcpy as a call be emitted if the built-in can not optimized.

Problem: When GET_FORMAT() is called two times from the upper level function (e.g. LEAST in the bug report), on the second call "res= args[0]->val_str(...)" and str point to the same String object. 1. Fix: changing the order from - get val_str into tmp_value then convert to str to - get val_str into str then convert to tmp_value The new order is more correct: the purpose of "str" parameter is exactly to call val_str() for arguments. The purpose of String class members (like tmp_value) is to do further actions on the result. Doing it in the other way around give unexpected surprises. 2. Using str_value instead of str to do padding, for the same reason.

Also delete dict_update_statistics() and rename dict_update_statistics_low() to dict_update_statistics() because the only thing that distinguished those two functions was the removed parameter.

Bug#57820 extractvalue crashes Problem: ExtractValue and Replace crashed in some cases due to invalid handling of empty and NULL arguments. Per file comments: @mysql-test/r/ctype_ujis.result @mysql-test/r/xml.result @mysql-test/t/ctype_ujis.test @mysql-test/t/xml.test Adding tests @sql/item_strfunc.cc Make sure Item_func_replace::val_str safely handles empty strings. @sql/item_xmlfunc.cc set null_value if nodeset_func returned NULL, which is possible when the second argument is an unset user variable.

The test result differs on windows, since it writes out 'localhost:<port>' instead of only 'localhost', since it uses tcp/ip instead of unix sockets on windows. Fixed by replacing that column. Also requires --big-test from some long running tests and added a weekly run of all test requiring --big-test. mysql-test/collections/default.weekly: Added a run of big-test (already exists in 5.5). mysql-test/r/variables-big.result: Updated results mysql-test/suite/parts/t/part_supported_sql_func_innodb.test: requiring --big-test since the test takes long time mysql-test/suite/parts/t/partition_alter1_1_2_innodb.test: requiring --big-test since the test takes long time mysql-test/suite/parts/t/partition_alter1_2_innodb.test: requiring --big-test since the test takes long time mysql-test/suite/parts/t/partition_alter4_innodb.test: requiring --big-test since the test takes long time mysql-test/t/disabled.def: Disabled two tests since they fail and was already reported as bugs (but was never run since they requires --big-test flag). mysql-test/t/variables-big.test: Replacing column 3 in process list since it is not the same on windows as in unix.
