causes out of memory errors The code in mysql_create_function() and mysql_drop_function() assumed that the only reason for UDFs being uninitialized at that point is an out-of-memory error during initialization. However, another possible reason for that is the --skip-grant-tables option in which case UDF initialization is skipped and UDFs are unavailable. The solution is to check whether mysqld is running with --skip-grant-tables and issue a proper error in such a case. mysql-test/r/skip_grants.result: Added a test case for bug #32020. mysql-test/t/skip_grants.test: Added a test case for bug #32020. sql/sql_udf.cc: Issue a proper error when a user tries to CREATE/DROP a UDF on a server running with the --skip-grant-tables option.
