if --skip-grant-tables specified. The problem is that there is a check that prevents creating a definer with empty host name. In --skip-grant-tables mode this check prevents the user from creating a trigger/view without explicitly specifying its definer. This happens, because in --skip-grant-tables mode CURRENT_USER is ''@''. According to Sanja this check was implemented intentionally. However, according to the MySQL manual it is possible to specify empty host name (as well as empty user name). Moreover, the behaviour for stored routines is different in this aspect -- we allow them to be created with implicit definer. Based on this, we believe it is OK to change the behaviour for views to be similar with the behaviour for stored routines. mysql-test/r/skip_grants.result: Added a test case for BUG#16777. mysql-test/t/skip_grants.test: Added a test case for BUG#16777. sql/mysql_priv.h: Do not check that strlen(host) > 0 in get_default_definer(). sql/sql_parse.cc: Do not check that strlen(host) > 0 in get_default_definer(). sql/sql_view.cc: Do not check that strlen(host) > 0 in get_default_definer().
