      BUG#29582: huge memory consumption with union, subselect, joins: · b4c0044e
      unknown authored
      - Don't call mysql_select() several times for the select that enumerates
        a temporary table with the results of the UNION. Making this call for
        every subquery execution caused O(#enumerated-rows-in-the-outer-query) 
        memory allocations.
      - Instead, call join->reinit() and join->exec(), and
        = disable constant table detection for such joins,  
        = provide special handling for table-less constant subqueries.

      Bug #29717 INSERT INTO SELECT inserts values even if · 86ae8436
      unknown authored
       SELECT statement itself returns empty.
      
      As a result of this bug 'SELECT AGGREGATE_FUNCTION(fld) ... GROUP BY'
      can return one row instead of an empty result set.
      
      When GROUP BY only has fields of constant tables
      (with a single row), the optimizer deletes the group_list.
      After that we lose the information about whether we had an
      GROUP BY statement. Though it's important
      as SELECT min(x) from empty_table; and
         SELECT min(x) from empty_table GROUP BY y; have to return
      different results - the first query should return one row,
      second - an empty result set.
      So here we add the 'group_optimized_away' flag to remember this case
      when GROUP BY exists in the query and is removed
      by the optimizer, and check this flag in end_send_group()

      Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
        
      Once had been set the flag might later got reset inside of a stored routine 
      execution stack.
      The reason was in that there was no check if a new statement started at time 
      of resetting.
      The artifact affects most of binlogable DML queries. Notice, that multi-update 
      is wrapped up within
        bug@27716 fix, multi-delete bug@29136.
        
      Fixed with saving parent's statement flag of whether the statement modified 
      non-transactional table, and unioning (merging) the value with that was gained 
      in mysql_execute_command.
        
      Resettling thd->no_trans_update members into thd->transaction.`member`;
      Asserting code;
      Effectively the following properties are held.
        
      1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
         reflects the fact if such a table got modified by the substatement.
         That also respects THD::really_abort_on_warnin() requirements.
      2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
         the union of the values of all invoked sub-statements.
         That fixes this bug#27417;
      
      Computing of thd->transaction.all.modified_non_trans_table is refined to base to 
      the stmt's value for all the case including insert .. select statement which 
      before the patch had an extra issue bug@28960.
      Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
      to temp_table select. 
        
      The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
      for bug@13270, bug@23333.

      Bug#24989: The DEADLOCK error is improperly handled by InnoDB. · 7186a2d7
      unknown authored
      When innodb detects a deadlock it calls ha_rollback_trans() to rollback the 
      main transaction. But such action isn't allowed from inside of triggers and
      functions. When it happen the 'Explicit or implicit commit' error is thrown
      even if there is no commit/rollback statements in the trigger/function. This
      leads to the user confusion.
      
      Now the convert_error_code_to_mysql() function doesn't call the 
      ha_rollback_trans() function directly but rather calls the
      mark_transaction_to_rollback function and returns an error.
      The sp_rcontext::find_handler() now doesn't allow errors to be caught by the
      trigger/function error handlers when the thd->is_fatal_sub_stmt_error flag
      is set. Procedures are still allowed to catch such errors.
      The sp_rcontext::find_handler function now accepts a THD handle as a parameter.
      The transaction_rollback_request and the is_fatal_sub_stmt_error flags are 
      added to the THD class. The are initialized by the THD class constructor.
      Now the ha_autocommit_or_rollback function rolls back main transaction
      when not in a sub statement and the thd->transaction_rollback_request
      is set.
      The THD::restore_sub_statement_state function now resets the 
      thd->is_fatal_sub_stmt_error flag on exit from a sub-statement.

      Fixed bug #30120. · bfea827a
      unknown authored
      SP with local variables with non-ASCII names crashed the server.
      
      The server replaces SP local variable names with NAME_CONST calls
      when putting statements into the binary log. It used UTF8-encoded
      item names as variable names for the replacement inside NAME_CONST
      calls. However, statement string may be encoded by any
      known character set by the SET NAMES statement.
      The server used byte length of UTF8-encoded names to increment
      the position in the query string that led to array index overrun.
      
      
      sql/item.cc:
        Fixed bug #30120.
        The Item_splocal class constructor has been modified to

        The Item_splocal class has been modified to keep new

        The subst_spvars function has been modified to increment
        position in the query string by the lengths of not

      Bug#30020: Insufficient check led to a wrong info provided by the · 8306d3dc
      unknown authored
      information schema table.
      
      The get_schema_views_record() function fills records in the view table of
      the informations schema with data about given views. Among other info
      the is_updatable flag is set. But the check whether the view is updatable or
      not wasn't covering all cases thus sometimes providing wrong info.
      This might led to a user confusion.
      
      Now the get_schema_views_record function additionally calls to the 
      view->can_be_merge() function to find out whether the view can be updated or
      not.

      Bug#29856: Insufficient buffer space led to a server crash. · a1e18414
      unknown authored
      The subst_spvars function is used to create query string with SP variables 
      substituted with their values. This string is used later for the binary log
      and for the query cache. The problem is that the
      query_cache_send_result_to_client function requires some additional space
      after the query to store database name and query cache flags. This 
      space wasn't reserved by the subst_spvars function which led to a memory
      corruption and crash.
      
      Now the subst_spvars function reserves additional space for the query cache.

      Bug #29878 Garbage data generation when executing SESSION_USER() on a slave. · e35c8aa4
      unknown authored
      Item_func_user doesn't calculate anything in it's val_str() method,
      just returns saved str_value.
      Though Item::save_in_field method can destroy str_value, relying on
      val_str() return. As a result we get the garbage stored in field.
      
      We cannot use Item::save_in_field implementation for Item_func_user,
      reimplement it in simpler way.

      BUG#29957 - alter_table.test fails · e011d300
      unknown authored
      INSERT/DELETE/UPDATE followed by ALTER TABLE within LOCK TABLES
      may cause table corruption on Windows.
      
      That happens because ALTER TABLE writes outdated shared state
      info into index file.
      
      Fixed by removing obsolete workaround.
      
      Affects MyISAM tables on Windows only.
      
      
      myisam/mi_extra.c:
        On windows when mi_extra(HA_EXTRA_PREPARE_FOR_DELETE) is called,
        we release external lock and close index file. If we're in LOCK
        TABLES, MyISAM state info doesn't get updated until UNLOCK TABLES.
        
        That means when we release external lock and we're in LOCK TABLES,
        we may write outdated state info.
        
        As SQL layer closes all table instances, we do not need this
        workaround anymore.

        A test case for BUG#29957.

      Bug #29571: INSERT DELAYED IGNORE written to binary log on · fb41c7da
      unknown authored
       the master but on the slave
      
      MySQL can decide to "downgrade" a INSERT DELAYED statement
      to normal insert in certain situations.
      One such situation is when the slave is replaying a 
      replication feed.
      However INSERT DELAYED is logged even if there're no updates
      whereas the NORMAL INSERT is not logged in such cases.
      
      Fixed by always logging a "downgraded" INSERT DELAYED: even 
      if there were no updates.

      Bug#25679 · 372ef902
      unknown authored
        "Federated Denial of Service"
        Federated storage engine used to attempt to open connections within
        the ::create() and ::open() methods which are invoked while LOCK_open
        mutex is being held by mysqld. As a result, no other client sessions
        can open tables while Federated is attempting to open a connection.
        Long DNS lookup times would stall mysqld's operation and a rogue
        connection string which connects to a remote server which simply
        stalls during handshake can stall mysqld for a much longer period of
        time.
        This patch moves the opening of the connection much later, when the
        federated actually issues queries, by which time the LOCK_open mutex is
        no longer being held.
