Gleb Shchepa 06142cd545 Bug #42778 : delete order by null global variable causes assertion .\filesort.cc, line 797 A query with the "ORDER BY @@some_system_variable" clause, where @@some_system_variable is NULL, causes assertion failure in the filesort procedures. The reason of the failure is in the value of Item_func_get_system_var::maybe_null: it was unconditionally set to false even if the value of a variable was NULL. mysql-test/r/variables.result: Added test case for bug #42778. mysql-test/suite/sys_vars/r/innodb_data_home_dir_basic.result: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/r/innodb_flush_method_basic.result: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/r/rpl_init_slave_func.result: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/r/ssl_capath_basic.result: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/r/ssl_cipher_basic.result: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/t/innodb_data_home_dir_basic.test: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/t/innodb_flush_method_basic.test: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/t/ssl_capath_basic.test: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/suite/sys_vars/t/ssl_cipher_basic.test: Updated test case for bug #42778: system variables were NOT NULL, now they are nullable. mysql-test/t/variables.test: Added test case for bug #42778. sql/item.cc: Bug #42778: delete order by null global variable causes assertion .\filesort.cc, line 797 The longlong_from_string_with_check function has been modified to skip unwanted warnings: now it uses the THD::no_errors flag to suppress warnings. The Item_func_get_system_var::update_null_value method sets the no_error flag. sql/item_func.cc: Bug #42778: delete order by null global variable causes assertion .\filesort.cc, line 797 1. The Item_func_get_system_var::fix_length_and_dec method has been modified to make system variables truly nullable. 2. The Item_func_get_system_var::update_null_value method method has been overloaded with a simple wrapper (like Item_field::update_null_value) to suppress unwanted warnings from Item_func_get_system_var::val_int() calls on non-numeric variable values: the Item_func_get_system_var::update_null_value method sets and restores THD::no_errors flag for a nested call of the longlong_from_string_with_check function. sql/item_func.h: Bug #42778: delete order by null global variable causes assertion .\filesort.cc, line 797 The Item_func_get_system_var::update_null_value method method has been overloaded.		17 years ago
