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.

# ==== Purpose ====
|
|
#
|
|
# Test that nondeterministic system functions are correctly replicated.
|
|
#
|
|
# (Some functions are only correctly replicated if binlog_format=MIXED
|
|
# or ROW. See binlog_unsafe.test for a test that those variables are
|
|
# indeed unsafe.)
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# We insert the values of each unsafe function into a table. Then we
|
|
# replicate and check that the table is identical on slave.
|
|
#
|
