Fixed stack overrun with some INSERT ... SELECT ... GROUP BY queries (Bug #3265)
Ensure that raid_chunks is not set to higher than 255 as this could cause problems with DROP DATABASE. (Bug #3182)
mysql-test/r/raid.result:
Test of raid_chunks > 255
mysql-test/t/raid.test:
Test of raid_chunks > 255
sql/item.cc:
Fixed wrong usage of str_value in Item::save_in_field
This could caused a stack overrun with some very special INSERT ... SELECT ... GROUP BY queries where the GROUP BY value was an expression that generated a NULL value. (Bug #3265)
The Item_copy_string::save_in_field() function is from 4.1 and helps optimized this case a bit
sql/item.h:
Fixed wrong usage of str_value in Item_copy_string::save_in_field
sql/sql_insert.cc:
More debug information
sql/table.cc:
Ensure that raid_chunks is not set to higher than 255 as this could cause problems with DROP DATABASE.
Another problem with values > 255 is that in the .frm file we store the chunks value in one byte.
