than an empty host '' is the same as any-host wildcard '%'.
Replace '' with '%' in the parser (for GRANT ... foo@'') and when loading grant tables.
Side effect: one cannot have foo@'' and foo@'%' both at the same time
(but one can have foo@'%' and foo@'%%')
because parser might modify the lex->user (e.g. set lex->user-password).
switch to use LEX_STRING current_user string, and also change other similar constants
to be LEX_STRING's for consistency.
mysql-test/r/acl_roles_show_grants.result:
one can do SHOW GRANTS for himself
mysql-test/t/acl_roles_set_role-table-column-priv.test:
correct error message
mysql-test/t/acl_roles_show_grants.test:
one can SHOW GRANTS for himself
sql/sql_acl.cc:
bugfixing:
* don't assign with && - it can shortcut and the second assignment won't be executed
* correct the test in check_grant_all_columns() - want_access should not be modified
*
sql/sql_cmd.h.OTHER:
add new commands at the end
sql/sql_db.cc:
don't call acl_get() if all privileges are already satisfied
(crashes when run with --skip-grants, because acl data stuctures aren't initialized)
sql/sql_parse.cc:
* test for current_user in get_current_user()
* map explicitly specified user@host to current_user
Also fixed issue with drop role not clearing internal memory entry
for that role. The issue was due to a condition introduced in handle_grant_data
Updated testsuite to also check the possible error conditions.
BNL and BNLH joins pre-filter the records from a joined table via JOIN_TAB::cache_select->cond.
There is no need to re-evaluate the same conditions via JOIN_TAB::select_cond. This patch removes
the duplicated conditions from the top-level conjuncts of each pushed condition.
The added "Using where" in few EXPLAINs is due to taking into account tab->cache_select->cond
in addition to tab->select_cond in JOIN::save_explain_data_intern.
