Error handling class for range optimizer.
We handle only out of memory error here. This is to give a hint to the user to raise range_optimizer_max_mem_size if required. Warning for the memory error is pushed only once. The consequent errors will be ignored.

Handle a sql condition.
This method can be implemented by a subclass to achieve any of the following:
This mechanism is similar to C++ try/throw/catch:
THD::push_internal_handler()
,my_error()
, which invokes my_message_sql()
,THD::pop_internal_handler()
.thd | the calling thread |
sql_errno | the error number for the condition raised. |
sqlstate | the SQLSTATE for the condition raised. |
level | the severity level for the condition raised. |
msg | the error message for the condition raised. |
Implements Internal_error_handler.
