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. |
