      BUG#46364 MyISAM transbuffer problems (NTM problem) · 5bedb960
      Alfranio Correia authored
            
      It is well-known that due to concurrency issues, a slave can become
      inconsistent when a transaction contains updates to both transaction and
      non-transactional tables.
                          
      In a nutshell, the current code-base tries to preserve causality among the
      statements by writing non-transactional statements to the txn-cache which
      is flushed upon commit. However, modifications done to non-transactional
      tables on behalf of a transaction become immediately visible to other
      connections but may not immediately get into the binary log and therefore
      consistency may be broken.
                  
      In general, it is impossible to automatically detect causality/dependency
      among statements by just analyzing the statements sent to the server. This
      happen because dependency may be hidden in the application code and it is
      necessary to know a priori all the statements processed in the context of
      a transaction such as in a procedure. Moreover, even for the few cases that
      we could automatically address in the server, the computation effort
      required could make the approach infeasible.
                  
      So, in this patch we introduce the option
            - "--binlog-direct-non-transactional-updates" that can be used to bypass
            the current behavior in order to write directly to binary log statements
            that change non-transactional tables.
      
      Besides, it is used to enable the WL#2687 which is disabled by default.
      
      mysql-test/extra/rpl_tests/rpl_binlog_max_cache_size.test:
        Changes the result set as the STMT mode behaves as both the ROW and MIXED modes and as such uses the non-trx-cache and takes longer to fill the trx-cache up and trigger an error.
      mysql-test/extra/rpl_tests/rpl_implicit_commit_binlog.test:
        Changes the result set as the STMT mode behaves as both the ROW and MIXED modes and as such uses the non-trx-cache. It also fixes comments.
      mysql-test/extra/rpl_tests/rpl_mixing_engines.test:
        The STMT mode is unsafe when mixed-statements are executed thus making slaves to go out of sync. For that reason, it checks consistency if not in STMT mode.
      mysql-test/include/default_mysqld.cnf:
        Makes binlog-direct-non-transactional-updates "TRUE" by default in the test
        cases.
      mysql-test/r/mysqld--help-notwin.result:
        Updates the result file with the new option.

        Updates the result file with the new option.
      mysql-test/suite/binlog/r/binlog_multi_engine.result:
        Updates the result file because non-trx-changes are written ahead of the
        transaction.

        within a transaction or a procedure/function/trigger.
      mysql-test/suite/binlog/t/binlog_stm_mix_innodb_myisam-master.opt:
        Sets binlog_direct_non_transactional_updates to FALSE in order to avoid changing
        the test case and its result file.
      mysql-test/suite/binlog/t/binlog_switch_inside_trans.test:

        Sets binlog_direct_non_transactional_updates to FALSE in order to avoid changing the test case and its result file.
      sql/log.cc:
        Verifies if changes should be written to either the trx-cache or non-trx-cache through the use of the function use_trans_cache(). It also organizes the code.
      sql/log.h:
        Changes the signature of some functions by adding the modifier "const" to the thd parameter. Specifically, the following functions are changed: 
                bool trans_has_updated_trans_table(const THD* thd);

      Fix for perfschema.binlog_stmt failure: · 05943ddd
      unknown authored
              
      Problem: The test case failed because: (i) warning text in 
               result file differed from the warning output by the 
               server, and (ii) binlog contents in result file did
               not show the statements logged wrapped in BEGIN/COMMIT
               as it is the case after WL 2687.
            
      Solution: We update the result file, but first we change the
                unsafe warning text to also refer to performance_schema
                table(s). This required changing the result files for
                existing test cases that provide output for warnings 
                related to ER_BINLOG_UNSAFE_SYSTEM_TABLE. "Grepping" in
                result files, shows that only binlog_unsafe contained
                reference to such a warning.
            
                We also update the result file with the missing 
                BEGIN/COMMIT statements.
