used causes server crash. When the loose index scan access method is used values of aggregated functions are precomputed by it. Aggregation of such functions shouldn't be performed in this case and functions should be treated as normal ones. The create_tmp_table function wasn't taking this into account and this led to a crash if a query has MIN/MAX aggregate functions and employs temporary table and loose index scan. Now the JOIN::exec and the create_tmp_table functions treat MIN/MAX aggregate functions as normal ones when the loose index scan is used. mysql-test/r/group_min_max.result: Added a test case for the bug#38195. mysql-test/t/group_min_max.test: Added a test case for the bug#38195. sql/sql_select.cc: Bug#38195: Incorrect handling of aggregate functions when loose index scan is used causes server crash. Now the JOIN::exec and the create_tmp_table functions treat MIN/MAX aggregate functions as normal ones when the loose index scan is used.

This fix is for 5.0 only : back porting the 6.0 patch manually The parser code in sql/sql_yacc.yy needs to be more robust to out of memory conditions, so that when parsing a query fails due to OOM, the thread gracefully returns an error. Before this fix, a new/alloc returning NULL could: - cause a crash, if dereferencing the NULL pointer, - produce a corrupted parsed tree, containing NULL nodes, - alter the semantic of a query, by silently dropping token values or nodes With this fix: - C++ constructors are *not* executed with a NULL "this" pointer when operator new fails. This is achieved by declaring "operator new" with a "throw ()" clause, so that a failed new gracefully returns NULL on OOM conditions. - calls to new/alloc are tested for a NULL result, - The thread diagnostic area is set to an error status when OOM occurs. This ensures that a request failing in the server properly returns an ER_OUT_OF_RESOURCES error to the client. - OOM conditions cause the parser to stop immediately (MYSQL_YYABORT). This prevents causing further crashes when using a partially built parsed tree in further rules in the parser. No test scripts are provided, since automating OOM failures is not instrumented in the server. Tested under the debugger, to verify that an error in alloc_root cause the thread to returns gracefully all the way to the client application, with an ER_OUT_OF_RESOURCES error.

running on Windows We used two OS-specific methods of looking up the executable name, which don't work outside of those two kinds of OSes (Linux+Solaris and Windows). We assume that if the user ran this program with a certain name, we can run the other sibling programs with a similar name. (re-patch in bzr)

min() and max() functions are implemented in MySQL as macros. This means that max(a,b) is expanded to: ((a) > (b) ? (a) : (b)) Note how 'a' is quoted two times. Now imagine 'a' is a recursive function call that's several 10s of levels deep. And the recursive function does max() with a function arg as well to dive into recursion. This means that simple function call can take most of the clock time. Identified and fixed several such calls to max()/min() : including the IF() sql function implementation. mysql-test/r/func_if.result: Bug#37662 test case mysql-test/t/func_if.test: Bug#37662 test case sql/item.cc: Bug#37662 don't call expensive functions as arguments to min/max sql/item_cmpfunc.cc: Bug#37662 don't call expensive functions as arguments to min/max sql/item_func.cc: Bug#37662 don't call expensive functions as arguments to min/max

Range scan in descending order for c <= <col> <= c type of ranges was ignoring the DESC flag. However some engines like InnoDB have the primary key parts as a suffix for every secondary key. When such primary key suffix is used for ordering ignoring the DESC is not valid. But we generally would like to do this because it's faster. Fixed by performing only reverse scan if the primary key is used. Removed some dead code in the process. mysql-test/r/innodb_mysql.result: Bug#37830 : test case mysql-test/t/innodb_mysql.test: Bug#37830 : test case sql/opt_range.cc: Bug#37830 : - preserve and use used_key_parts to distinguish when a primary key suffix is used - removed some dead code sql/opt_range.h: Bug#37830 : - preserve used_key_parts - dead code removed sql/sql_select.cc: Bug#37830 : Do only reverse order traversal if the primary key suffix is used.
