Let us assume the following function:
void function(void)
{
DBUG_CRASH_ENTER("function");
if (DBUG_EVALUATE_IF("process_if", 1, 0))
{
DBUG_EXECUTE_IF("process_code", {
const char *old_proc_info= thd->proc_info;
thd->proc_info= "DBUG sleep";
my_sleep(6000000);
thd->proc_info= old_proc_info;});
}
DBUG_CRASH_VOID_RETURN;
}
To crash the server in the fault points defined above, we need to
be SUPER user and execute one of
the following statements:
SET SESSION debug="+d,function_crash_enter";will crash the server while entering the function.
SET SESSION debug="+d,function_crash_return";will crash the server while returning from function.
SET SESSION debug="+d,process_if";will execute the code inside theif.
SET SESSION debug="+d,process_code";will execute thesleepcode.
