It doesn't make sense to allow selects from I_S but disallow selects that don't use any tables at all, because any (disallowed) select that doesn't use tables can be made allowed by adding "FROM I_S.COLLATIONS LIMIT 1" to the end. And it break mysql-test rather badly, even check-testcase.test fails on its first `SELECT '$tmp' = 'No such row'` This reverts9a89614857,c5dd2abf4c, and33028f7c4b: Refs: MW-245 - changed logic so that in non primary node it is possible to do SET + SHOW + SELECT from information and pfs schema, when dirty reads are not enabled - however, non table selects are not allowed (e.g. SELECT 1) Refs MW-245 - logic was wrong in detecting if queries are allowed in non primary node. it allowed select with no table list to execute even if dirty reads was not specified Refs: MW-245 - Adjust tests to account for the new behavior.
