      Bug #50192 Strange effect in replication test, trigger, auto_increment · 8d240586
      Andrei Elkin authored
      The auto-inc unsafe warning makes sense even though it's just
      one auto-inc table could be involved via a trigger or a stored
      function.
      However its content was not updated by bug@45677 fixes continuing to mention
      two tables whereas the fixes refined semantics of replication of auto_increment 
      in stored routine.
      
      Fixed with updating the error message, renaming the error and an internal unsafe-condition 
      constants.
      
      A documentation notice
      ======================
      
            Inserting into an autoincrement column in a stored function or a trigger
            is unsafe for replication.
            Even with just one autoincrement column, if the routine is invoked more than 
            once slave is not guaranteed to execute the statement graph same way as 
            the master.
            And since it's impossible to estimate how many times a routine can be invoked at 
            the query pre-execution phase (see lock_tables), the statement is marked
            pessimistically unsafe.

      BUG#46364 MyISAM transbuffer problems (NTM problem) · 0efac646
      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.

      Fix for perfschema.binlog_stmt failure: · 5d279205
      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.

      Fix for Bug#50221 Server refuses to start from non-default installdir on Solaris 32-bit · ec680f0a
      Olav Sandstaa authored
      When starting mysqld it did not recognize most of the options given on
      the command line when it was compiled for 32-bit Solaris using Sun
      Studio compiler. The cause for this was that most of the entries in
      the my_long_options array contained "garbage" data. The garbage data
      was caused by a compiler bug. When initilizing the def_value member
      for the "default-storage-engine" entry it was initialized like this:
      
        (longlong)"MyISAM"
      
      i.e. casting a 32 bit pointer to a 64 bit integer value. Due to the
      compiler bug only 4 bytes was allocated (instead of 8 bytes). This
      caused everything following this entry to be stored at a location that
      was 4 byte wrong.
      
      The fix/work-around for this problem is initialize the def_value
      for default-storage-engine in my_long_options to 0 and instead
      initialize the default_storage_engine variable to "MyISAM" in
      init_common_variables().
      
      sql/mysqld.cc:
        Due to a bug in Sun Studio compiler when generating 32 bit code the 
        initialization of the def_value member of the default-storage-engine entry 
        in my_long_options only got 4 bytes allocated instead of 8 bytes. 
        The compiler bug was triggered by casting a 32 bit pointer to a 64 bit 
        integer value in the initialization code for my_long_options. To avoid 
        triggering the compiler bug the intialization of the def_value in
        my_long_options is set to 0 and instead the default_storage_engine
        is initialized to "MyISAM" in init_common_variables().
