      A fix for Bug#14845 "mysql_stmt_fetch returns MYSQL_NO_DATA when · db869810
      unknown authored
      COUNT(*) is 0" (the test case has been pushed already)
      
      
      sql/sql_cursor.cc:
        Fix a return of an unitialized variable: return_zero_rows
        checks the return value of send_fields and in case it's 1
        doesn't call send_data. This caused creation of an empty result 
        set for the case when there is a cursor against a select with a 
        group function and no matching rows.

      Fix for bug #13825 "Triggers: crash if release savepoint" and for general · 2722ebcd
      unknown authored
      handling of savepoints in stored routines.
      
      Fixed ha_rollback_to_savepoint()/ha_savepoint()/ha_release_savepoint()
      functions to properly handle savepoints inside of stored functions and
      triggers.
      Also now when we invoke stored function or trigger we create new savepoint
      level. We destroy it at the end of function/trigger execution and return back
      to old savepoint level.
      
      
      mysql-test/r/sp_trans.result:
        Added test for bug #13825 "Triggers: crash if release savepoint" and for
        general handling of savepoints in stored routines.
      mysql-test/t/sp_trans.test:
        Added test for bug #13825 "Triggers: crash if release savepoint" and for
        general handling of savepoints in stored routines.
      sql/ha_innodb.cc:
        innobase_savepoint():
          Replaced check which always failed due to similar check in caller
          with assertion.
      sql/handler.cc:
        ha_rollback_to_savepoint()/ha_savepoint()/ha_release_savepoint():
          Changed functions to properly support handling of savepoints
          inside of stored functions and triggers.
      sql/sql_class.cc:
        THD::reset_sub_statement_state()/restore_sub_statement_state():
          When we invoke stored function or trigger we should create new savepoint
          level. We should destroy it at the end of function/trigger execution and
          return back to old savepoint level. To support this behavior we should
          save and reset list of current savepoints on entering function and restore
          old list when we leave it.
      sql/sql_class.h:
        Sub_statement_state:
          When we invoke stored function or trigger we should create new savepoint
          level. We should destroy it at the end of function/trigger execution and
          return back to old savepoint level. To support this behavior added "savepoint"
          member which is used to save/restore list of current savepoints on
          entering/leaving function.
      sql/sql_parse.cc:
        mysql_execute_command():
          Changed processing of SQLCOM_SAVEPOINT so now it is not ignored when
          we are in autocommit mode and savepoint is set inside of stored
          function or trigger.
