I came across the following gcc warning (6.3.1)
sql/item_sum.cc: In member function ‘virtual bool Item_func_group_concat::fix_fields(THD*, Item**)’: sql/item_sum.cc:3478:5: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation] if ((!args[i]->fixed && ^~ sql/item_sum.cc:3482:7: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘if’ with_subselect|= args[i]->with_subselect;
The with_subselect line was added in 950abd526
In context it is:
Item_func_group_concat::fix_fields(THD *thd, Item **ref) { ... for (i=0 ; i < arg_count ; i++) { if ((!args[i]->fixed && args[i]->fix_fields(thd, args + i)) || args[i]->check_cols(1)) return TRUE; with_subselect|= args[i]->with_subselect; }
While removing the indent would fix the warning, I'd like someone to check this line should be after the IF statement rather than before.
I've fixed the indentation (in 5.5). Returning TRUE means an error anyway, the query processing is aborted. It shouldn't matter what with_subselect is in that case. Regards, Sergei Chief Architect MariaDB and security@mariadb.org
