Problem: Some system functions that could return different values on
master and slave were not marked unsafe. In particular:
GET_LOCK
IS_FREE_LOCK
IS_USED_LOCK
MASTER_POS_WAIT
RELEASE_LOCK
SLEEP
SYSDATE
VERSION
Fix: Mark these functions unsafe.
mysql-test/extra/rpl_tests/rpl_stm_000001.test:
- The test does not work in mixed mode any more, since it tries to
simulate an error in the sql thread in a query that uses get_lock.
Since get_lock now causes the query to be logged in row format,
the error didn't happen. Hence, we now force statement mode.
- Warnings must be disabled when the unsafe query is issued.
- Replaced some save_master_pos+connection slave+sync_with_master
by sync_slave_with_master.
mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result:
updated result file
mysql-test/suite/binlog/r/binlog_stm_row.result:
updated result file
mysql-test/suite/binlog/r/binlog_unsafe.result:
updated result file
mysql-test/suite/binlog/t/binlog_killed.test:
binlog_killed only works in statement format now, since
it switches to row mode in mixed mode.
mysql-test/suite/binlog/t/binlog_stm_mix_innodb_myisam.test:
suppress warnings for unsafe statements
mysql-test/suite/binlog/t/binlog_stm_row.test:
- Suppress warnings in test that causes warnings.
- The test sets binlog format explicitly, so no need to execute it
twice.
mysql-test/suite/binlog/t/binlog_unsafe.test:
Added test for all unsafe system functions. This test also includes
system functions that were unsafe prior to BUG#47995.
mysql-test/suite/rpl/r/rpl_err_ignoredtable.result:
updated result file
mysql-test/suite/rpl/r/rpl_get_lock.result:
updated result file
mysql-test/suite/rpl/r/rpl_nondeterministic_functions.result:
new result file
mysql-test/suite/rpl/r/rpl_stm_000001.result:
updated result file
mysql-test/suite/rpl/r/rpl_trigger.result:
updated result file
mysql-test/suite/rpl/t/rpl_err_ignoredtable.test:
- suppress warnings for unsafe statement
- replaced save_master_pos+connection slave+sync_with_master
with sync_slave_with_master
mysql-test/suite/rpl/t/rpl_get_lock.test:
update test case that causes new warnings
mysql-test/suite/rpl/t/rpl_nondeterministic_functions.test:
Added new test case for nondeterministic functions.
mysql-test/suite/rpl/t/rpl_trigger.test:
update test case that causes new warnings
sql/item_create.cc:
Marked some system functions unsafe.
sql/item_strfunc.cc:
Clarified comment related to this bug.
sql/sql_yacc.yy:
Marked sysdate unsafe.
