Problem: in mixed and statement mode, a query that refers to a system variable will use the slave's value when replayed on slave. So if the value of a system variable is inserted into a table, the slave will differ from the master. Fix: mark statements that refer to a system variable as "unsafe", meaning they will be replicated by row in mixed mode and produce a warning in statement mode. There are some exceptions: some variables are actually replicated. Those should *not* be marked as unsafe. BUG#34732: mysqlbinlog does not print default values for auto_increment variables Problem: mysqlbinlog does not print default values for some variables, including auto_increment_increment and others. So if a client executing the output of mysqlbinlog has different default values, replication will be wrong. Fix: Always print default values for all variables that are replicated. I need to fix the two bugs at the same time, because the test cases would fail if I only fixed one of them. include/m_ctype.h: Added definition of ILLEGAL_CHARSET_INFO_NUMBER. We just need a symbol for a number that will never be used by any charset. ~0U should be safe since charset numbers are sequential, starting from 0. mysql-test/include/commit.inc: Upated test to avoid making statements unsafe. mysql-test/r/commit_1innodb.result: Updated test needs updated result file. mysql-test/r/mysqlbinlog.result: Updated result file. mysql-test/r/mysqlbinlog2.result: Updated result file. mysql-test/r/user_var-binlog.result: Updated result file. mysql-test/suite/binlog/r/binlog_base64_flag.result: Updated result file. mysql-test/suite/binlog/r/binlog_stm_ctype_ucs.result: Updated result file. mysql-test/suite/binlog/r/binlog_unsafe.result: Modified test file needs modified result file. mysql-test/suite/binlog/t/binlog_base64_flag.test: Need to filter out pseudo_thread_id from result since it is nondeterministic. mysql-test/suite/binlog/t/binlog_unsafe.test: Add tests that using variables is unsafe. The 'CREATE VIEW' tests didn't make sense, so I removed them. SHOW WARNINGS is not necessary either, because we get warnings for each statement in the result file. mysql-test/suite/rpl/r/rpl_row_mysqlbinlog.result: Updated result file. mysql-test/suite/rpl/r/rpl_skip_error.result: Updated result file. mysql-test/suite/rpl/t/rpl_skip_error.test: The test used @@server_id, which is not safe to replicate, so it would have given a warning. The way it used @@server_id was hackish (issue a query on master that removes rows only on master), so I replaced it by a more robust way to do the same thing (connect to slave and insert the rows only there). Also clarified what the test case does. mysql-test/t/mysqlbinlog2.test: Use --short-form instead of manually filtering out nondeterministic stuff from mysqlbinlog (because we added the nondeterministic @@pseudo_thread_id to the output). sql/item_func.cc: Added method of Item_func_get_system_var that indicates whether the given system variable will be written to the binlog or not. sql/item_func.h: Added method of Item_func_get_system_var that indicates whether the given system variable will be written to the binlog or not. sql/log_event.cc: - auto_increment_offset was not written to the binlog if auto_increment_increment=1 - mysqlbinlog did not output default values for some variables (BUG#34732). In st_print_event_info, we remember for each variable whether it has been printed or not. This is achieved in different ways for different variables: - For auto_increment_*, lc_time_names, charset_database_number, we set the default values in st_print_event_info to something illegal, so that it will look like they have changed the first time they are seen. - For charset, sql_mode, pseudo_thread_id, we add a flag to st_print_event_info which indicates whether the variable has been printed. - Since pseudo_thread_id is now printed more often, and its value is not guaranteed to be constant across different runs of the same test script, I replaced it by a constant if --short-form is used. - Moved st_print_event_info constructor from log_event.h to log_event.cc, since it now depends on ILLEGAL_CHARSET_NUMBER, which is defined in m_ctype.h, which is better to include from a .cc file than from a header file. sql/log_event.h: Added fields to st_print_event_info that indicate whether some of the variables have been written or not. Since the initialization of charset_database_number now depends on ILLEGAL_CHARSET_INFO_NUMBER, which is defined in a header file, which we'd better not include from this header file -- I moved the constructor from here to log_event.cc. sql/set_var.cc: System variables now have a flag binlog_status, which indicates if they are written to the binlog. If nothing is specified, all variables are marked as not written to the binlog (NOT_IN_BINLOG) when created. In this file, the variables that are written to the binlog are marked with SESSION_VARIABLE_IN_BINLOG. sql/set_var.h: Added flag binlog_status to class sys_var. Added a getter and a constructor parameter that sets it. Since I had to change sys_var_thd_enum constructor anyways, I simplified it to use default values of arguments instead of three copies of the constructor. sql/sql_yacc.yy: Mark statements that refer to a system variable as "unsafe", meaning they will be replicated by row in mixed mode. Added comment to explain strange piece of code just above. mysql-test/include/diff_tables.inc: New auxiliary test file that tests whether two tables (possibly one on master and one on slave) differ. mysql-test/suite/rpl/r/rpl_variables.result: New test case needs new result file. mysql-test/suite/rpl/r/rpl_variables_stm.result: New test file needs new result file. mysql-test/suite/rpl/t/rpl_variables.test: Test that INSERT of @@variables is replicated correctly (by switching to row-based mode). mysql-test/suite/rpl/t/rpl_variables_stm.test: Test that replication of @@variables which are replicated explicitly works as expected in statement mode (without giving warnings).
