      Removed logic in ha_federated::write_row, which checks field query ids in the
      loop which builds the query to run on the remote server.

        New test results for test that verifies that one can insert to rows using

        Removed the logic in ha_federated::write_row which checked the query id of 
        each field and compared it to the thread query id.
        
        Each field has a query id, and the problem used to be that if I did an insert
        no fields specified, the field value would contain the last inserted value 
        for that field. The way to work around this was to see if the query id for 
        that field was the same as the current query id or of the rest of the field 
        query ids. If it wasn't, that told me the query didn't have the field value 
        specified.
        
        Somewhere from when I wrote that code to now the problem went away, and there
        was no longer the need for this logic. 
        
        Also removed the bool "has_fields", which needs not exist and using 
        table->s->fields is sufficient.

      Bug #17608: String literals lost during INSERT query on FEDERATED table · abbf7ad0
      unknown authored
        The Federated storage engine used Field methods that had arbitrary limits on
        the amount of data they could process, which caused problems with data
        over that limit (4K). By removing those Field methods and just using
        features of the String class, we can avoid this problem.

      After merge fixes for patch solving bug#18437 "Wrong values inserted with a · 0e47753f
      unknown authored
      before update trigger on NDB table".
      
      Two main changes:
      - We use TABLE::read_set/write_set bitmaps for marking fields used by
        statement instead of Field::query_id in 5.1.
      - Now when we mark columns used by statement we take into account columns 
        used by table's triggers instead of marking all columns as used if table
        has triggers.
      
      
      mysql-test/r/federated.result:
        Changed test in order to make it work with RBR.
        RBR changes the way in which we execute "DELETE FROM t1" statement - we don't
        use handler::delete_all_rows() method if RBR is enabled (see bug#19066).
        As result federated engine produces different sequences of statements for
        remote server in non-RBR and in RBR cases. And this changes order of the
        rows inserted by following INSERT statements.
      mysql-test/t/federated.test:
        Changed test in order to make it work with RBR.
        RBR changes the way in which we execute "DELETE FROM t1" statement - we don't
        use handler::delete_all_rows() method if RBR is enabled (see bug#19066).
        As result federated engine produces different sequences of statements for
        remote server in non-RBR and in RBR cases. And this changes order of the
        rows inserted by following INSERT statements.
      sql/ha_partition.cc:
        Added handling of HA_EXTRA_WRITE_CAN_REPLACE/HA_EXTRA_WRITE_CANNOT_REPLACE
        to ha_partition::extra().
      sql/item.cc:
        Adjusted comment after merge. In 5.1 we use TABLE::read_set/write_set
        bitmaps instead of Field::query_id for marking columns used.
      sql/log_event.cc:
        Write_rows_log_event::do_before_row_operations():
          Now we explicitly inform handler that we want to replace rows so it can
          promote operation done by write_row() to replace.
      sql/mysql_priv.h:
        Removed declaration of mark_fields_used_by_triggers_for_insert_stmt() which
        is no longer used (we have TABLE::mark_columns_needed_for_insert() instead).
      sql/sql_insert.cc:
        Adjusted code after merge. Get rid of mark_fields_used_by_triggers_for_insert_stmt()
        as now we use TABLE::mark_columns_needed_for_insert() for the same purprose.
        Aligned places where we call this method with places where we call
        mark_fields_used_by_triggers_for_insert() in 5.0.
        Finally we no longer need to call handler::extra(HA_EXTRA_WRITE_CAN_REPLACE)
        in case of REPLACE statement since in 5.1 write_record() marks all columns
        as used before doing actual row replacement.
      sql/sql_load.cc:
        Adjusted code after merge. In 5.1 we use TABLE::mark_columns_needed_for_insert() instead of
        mark_fields_used_by_triggers_for_insert_stmt() routine. We also no longer
        need to call handler::extra(HA_EXTRA_RETRIEVE_ALL_COLS) if we execute LOAD
        DATA REPLACE since in 5.1 write_record() will mark all columns as used before
        doing actual row replacement.
      sql/sql_trigger.cc:
        Table_triggers_list::mark_fields_used():
          We use TABLE::read_set/write_set bitmaps for marking fields used instead
          of Field::query_id in 5.1.
      sql/sql_trigger.h:
        TABLE::mark_columns_needed_for_* methods no longer need to be friends of
        Table_triggers_list class as intead of dirrectly accessing its private
        members they can use public Table_triggers_list::mark_fields_used() method.
        Also Table_triggers)list::mark_fields_used() no longer needs THD argument.
      sql/table.cc:
        TABLE::mark_columns_needed_for_*():
          Now we mark columns which are really used by table's triggers instead of
          marking all columns as used if table has triggers.

      Fix for bug#18437 "Wrong values inserted with a before update trigger on · ae9724cc
      unknown authored
      NDB table".
      
      SQL-layer was not marking fields which were used in triggers as such. As
      result these fields were not always properly retrieved/stored by handler
      layer. So one might got wrong values or lost changes in triggers for NDB,
      Federated and possibly InnoDB tables.
      This fix solves the problem by marking fields used in triggers
      appropriately.
      
      Also this patch contains the following cleanup of ha_ndbcluster code:
      
      We no longer rely on reading LEX::sql_command value in handler in order
      to determine if we can enable optimization which allows us to handle REPLACE
      statement in more efficient way by doing replaces directly in write_row()
      method without reporting error to SQL-layer.
      Instead we rely on SQL-layer informing us whether this optimization
      applicable by calling handler::extra() method with
      HA_EXTRA_WRITE_CAN_REPLACE flag.
      As result we no longer apply this optimzation in cases when it should not
      be used (e.g. if we have on delete triggers on table) and use in some
      additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
      
      Finally this patch includes fix for bug#20728 "REPLACE does not work
      correctly for NDB table with PK and unique index".
        
      This was yet another problem which was caused by improper field mark-up.
      During row replacement fields which weren't explicity used in REPLACE
      statement were not marked as fields to be saved (updated) so they have
      retained values from old row version. The fix is to mark all table
      fields as set for REPLACE statement. Note that in 5.1 we already solve
      this problem by notifying handler that it should save values from all
      fields only in case when real replacement happens.
      
      
      include/my_base.h:
        Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
        parameters for ha_extra() method. We use them to inform handler that
        write_row() which tries to insert new row into the table and encounters
        some already existing row with same primary/unique key can replace old
        row with new row instead of reporting error.
      mysql-test/r/federated.result:
        Additional test for bug#18437 "Wrong values inserted with a before update
        trigger on NDB table".
      mysql-test/r/ndb_replace.result:
        Added test for bug #20728 "REPLACE does not work correctly for NDB table
        with PK and unique index". Updated wrong results from older test.
      mysql-test/t/federated.test:
        Additional test for bug#18437 "Wrong values inserted with a before update
        trigger on NDB table".
      mysql-test/t/ndb_replace.test:
        Added test for bug #20728 "REPLACE does not work correctly for NDB table
        with PK and unique index".
      sql/ha_ndbcluster.cc:
        We no longer rely on reading LEX::sql_command value in handler in order
        to determine if we can enable optimization which allows us to handle REPLACE
        statement in more efficient way by doing replaces directly in write_row()
        method without reporting error to SQL-layer.
        Instead we rely on SQL-layer informing us whether this optimization
        applicable by calling handler::extra() method with
        HA_EXTRA_WRITE_CAN_REPLACE flag.
        As result we no longer apply this optimization in cases when it should not
        be used (e.g. if we have on delete triggers on table) and use in some
        additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
      sql/item.cc:
        Item_trigger_field::setup_field():
          Added comment explaining why we don't set Field::query_id in this method.
      sql/mysql_priv.h:
        mysql_alter_table() function no longer takes handle_duplicates argument.
        Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function.
      sql/sql_delete.cc:
        Mark fields which are used by ON DELETE triggers so handler will retrieve
        values for these fields.
      sql/sql_insert.cc:
        Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
        in cases when it can promote insert operation done by write_row() to replace.
        Also when we do REPLACE we want to store values for all columns so we should
        inform handler about it.
        Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
        so handler can properly retrieve/restore values in these fields during
        execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
      sql/sql_load.cc:
        Explicitly inform handler that we are doing LOAD DATA REPLACE (using
        ha_extra() method) in cases when it can promote insert operation done by
        write_row() to replace.
        Also when we do replace we want to save (replace) values for all columns
        so we should inform handler about it.
        Finally to properly execute LOAD DATA for table with triggers we should
        mark fields used by ON INSERT triggers as such so handler can properly
        store values for these fields.
      sql/sql_parse.cc:
        mysql_alter_table() function no longer takes handle_duplicates argument.
      sql/sql_table.cc:
        Got rid of handle_duplicates argument in mysql_alter_table() and
        copy_data_between_tables() functions. These functions were always
        called with handle_duplicates == DUP_ERROR and thus contained dead
        (and probably incorrect) code.
      sql/sql_trigger.cc:
        Added Table_triggers_list::mark_fields_used() method which is used to mark
        fields read/set by triggers as such so handlers will be able properly
        retrieve/store values in these fields.
      sql/sql_trigger.h:
        Table_triggers_list:
          Added mark_fields_used() method which is used to mark fields read/set by
          triggers as such so handlers will be able properly retrieve/store values
          in these fields. To implement this method added 'trigger_fields' member
          which is array of lists linking items for all fields used in triggers
          grouped by event and action time.
      sql/sql_update.cc:
        Mark fields which are used by ON UPDATE triggers so handler will retrieve
        and save values for these fields.
      mysql-test/r/ndb_trigger.result:
        Added test for bug#18437 "Wrong values inserted with a before update trigger
        on NDB table".
      mysql-test/t/ndb_trigger.test:
        Added test for bug#18437 "Wrong values inserted with a before update trigger
        on NDB table".

        Post-review changes, per Monty. 3rd patch, OK'd for push.
        - Added index_read_idx_with_result_set, which uses the result set passed to it
        - Hash by entire connection scheme
        - Protected store_result result set for table scan by adding a method result set
          to index_read_idx and index_read which is passed to index_read_with_result, which
          in turn iterates over the single record via read_next.
          This is a change from having two result sets in the first two patches. 
          This keeps the code clean and avoids the need for yet another result set.
        - Rewrote ::position and ::rnd_pos to store position - if primary key use 
          primary key, if not, use record buffer.
        - Rewrote get_share to store hash with connect string vs. table name
        - delete_row added subtration of "records" by affected->rows
        - Added read_next to handle what rnd_next used to do (converting raw record
           to query and vice versa)
        - Removed many DBUG_PRINT lines
        - Removed memset initialisation since subsequent loop accomplishes

      unknown authored
       When building the UPDATE query to send to the remote server, the
       federated storage engine built the query incorrectly if it was updating
       a field to be NULL.

      unknown authored
      This changeset is largely a handler cleanup changeset (WL#3281), but includes fixes and cleanups that was found necessary while testing the handler changes
      
      Changes that requires code changes in other code of other storage engines.
      (Note that all changes are very straightforward and one should find all issues
      by compiling a --debug build and fixing all compiler errors and all
      asserts in field.cc while running the test suite),
      
      - New optional handler function introduced: reset()
        This is called after every DML statement to make it easy for a handler to
        statement specific cleanups.
        (The only case it's not called is if force the file to be closed)
      
      - handler::extra(HA_EXTRA_RESET) is removed. Code that was there before
        should be moved to handler::reset()
      
      - table->read_set contains a bitmap over all columns that are needed
        in the query.  read_row() and similar functions only needs to read these
        columns
      - table->write_set contains a bitmap over all columns that will be updated
        in the query. write_row() and update_row() only needs to update these
        columns.
        The above bitmaps should now be up to date in all context
        (including ALTER TABLE, filesort()).
      
        The handler is informed of any changes to the bitmap after
        fix_fields() by calling the virtual function
        handler::column_bitmaps_signal(). If the handler does caching of
        these bitmaps (instead of using table->read_set, table->write_set),
        it should redo the caching in this code. as the signal() may be sent
        several times, it's probably best to set a variable in the signal
        and redo the caching on read_row() / write_row() if the variable was
        set.
      
      - Removed the read_set and write_set bitmap objects from the handler class
      
      - Removed all column bit handling functions from the handler class.
        (Now one instead uses the normal bitmap functions in my_bitmap.c instead
        of handler dedicated bitmap functions)
      
      - field->query_id is removed. One should instead instead check
        table->read_set and table->write_set if a field is used in the query.
      
      - handler::extra(HA_EXTRA_RETRIVE_ALL_COLS) and
        handler::extra(HA_EXTRA_RETRIEVE_PRIMARY_KEY) are removed. One should now
        instead use table->read_set to check for which columns to retrieve.
      
      - If a handler needs to call Field->val() or Field->store() on columns
        that are not used in the query, one should install a temporary
        all-columns-used map while doing so. For this, we provide the following
        functions:
      
        my_bitmap_map *old_map= dbug_tmp_use_all_columns(table, table->read_set);
        field->val();
        dbug_tmp_restore_column_map(table->read_set, old_map);
      
        and similar for the write map:
      
        my_bitmap_map *old_map= dbug_tmp_use_all_columns(table, table->write_set);
        field->val();
        dbug_tmp_restore_column_map(table->write_set, old_map);
      
        If this is not done, you will sooner or later hit a DBUG_ASSERT
        in the field store() / val() functions.
        (For not DBUG binaries, the dbug_tmp_restore_column_map() and
        dbug_tmp_restore_column_map() are inline dummy functions and should
        be optimized away be the compiler).
      
      - If one needs to temporary set the column map for all binaries (and not
        just to avoid the DBUG_ASSERT() in the Field::store() / Field::val()
        methods) one should use the functions tmp_use_all_columns() and
        tmp_restore_column_map() instead of the above dbug_ variants.
      
      - All 'status' fields in the handler base class (like records,
        data_file_length etc) are now stored in a 'stats' struct. This makes
        it easier to know what status variables are provided by the base
        handler.  This requires some trivial variable names in the extra()
        function.
      
      - New virtual function handler::records().  This is called to optimize
        COUNT(*) if (handler::table_flags() & HA_HAS_RECORDS()) is true.
        (stats.records is not supposed to be an exact value. It's only has to
        be 'reasonable enough' for the optimizer to be able to choose a good
        optimization path).
      
      - Non virtual handler::init() function added for caching of virtual
        constants from engine.
      
      - Removed has_transactions() virtual method. Now one should instead return
        HA_NO_TRANSACTIONS in table_flags() if the table handler DOES NOT support
        transactions.
      
      - The 'xxxx_create_handler()' function now has a MEM_ROOT_root argument
        that is to be used with 'new handler_name()' to allocate the handler
        in the right area.  The xxxx_create_handler() function is also
        responsible for any initialization of the object before returning.
      
        For example, one should change:
      
        static handler *myisam_create_handler(TABLE_SHARE *table)
        {
          return new ha_myisam(table);
        }
      
        ->
      
        static handler *myisam_create_handler(TABLE_SHARE *table, MEM_ROOT *mem_root)
        {
          return new (mem_root) ha_myisam(table);
        }
      
      - New optional virtual function: use_hidden_primary_key().
        This is called in case of an update/delete when
        (table_flags() and HA_PRIMARY_KEY_REQUIRED_FOR_DELETE) is defined
        but we don't have a primary key. This allows the handler to take precisions
        in remembering any hidden primary key to able to update/delete any
        found row. The default handler marks all columns to be read.
      
      - handler::table_flags() now returns a ulonglong (to allow for more flags).
      
      - New/changed table_flags()
        - HA_HAS_RECORDS	    Set if ::records() is supported
        - HA_NO_TRANSACTIONS	    Set if engine doesn't support transactions
        - HA_PRIMARY_KEY_REQUIRED_FOR_DELETE
                                  Set if we should mark all primary key columns for
      			    read when reading rows as part of a DELETE
      			    statement. If there is no primary key,
      			    all columns are marked for read.
        - HA_PARTIAL_COLUMN_READ  Set if engine will not read all columns in some
      			    cases (based on table->read_set)
       - HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS
         			    Renamed to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION.
       - HA_DUPP_POS              Renamed to HA_DUPLICATE_POS
       - HA_REQUIRES_KEY_COLUMNS_FOR_DELETE
      			    Set this if we should mark ALL key columns for
      			    read when when reading rows as part of a DELETE
      			    statement. In case of an update we will mark
      			    all keys for read for which key part changed
      			    value.
        - HA_STATS_RECORDS_IS_EXACT
      			     Set this if stats.records is exact.
      			     (This saves us some extra records() calls
      			     when optimizing COUNT(*))
      			    
      
      - Removed table_flags()
        - HA_NOT_EXACT_COUNT     Now one should instead use HA_HAS_RECORDS if
      			   handler::records() gives an exact count() and
      			   HA_STATS_RECORDS_IS_EXACT if stats.records is exact.
        - HA_READ_RND_SAME	   Removed (no one supported this one)
      
      - Removed not needed functions ha_retrieve_all_cols() and ha_retrieve_all_pk()
      
      - Renamed handler::dupp_pos to handler::dup_pos
      
      - Removed not used variable handler::sortkey
      
      
      Upper level handler changes:
      
      - ha_reset() now does some overall checks and calls ::reset()
      - ha_table_flags() added. This is a cached version of table_flags(). The
        cache is updated on engine creation time and updated on open.
      
      
      MySQL level changes (not obvious from the above):
      
      - DBUG_ASSERT() added to check that column usage matches what is set
        in the column usage bit maps. (This found a LOT of bugs in current
        column marking code).
      
      - In 5.1 before, all used columns was marked in read_set and only updated
        columns was marked in write_set. Now we only mark columns for which we
        need a value in read_set.
      
      - Column bitmaps are created in open_binary_frm() and open_table_from_share().
        (Before this was in table.cc)
      
      - handler::table_flags() calls are replaced with handler::ha_table_flags()
      
      - For calling field->val() you must have the corresponding bit set in
        table->read_set. For calling field->store() you must have the
        corresponding bit set in table->write_set. (There are asserts in
        all store()/val() functions to catch wrong usage)
      
      - thd->set_query_id is renamed to thd->mark_used_columns and instead
        of setting this to an integer value, this has now the values:
        MARK_COLUMNS_NONE, MARK_COLUMNS_READ, MARK_COLUMNS_WRITE
        Changed also all variables named 'set_query_id' to mark_used_columns.
      
      - In filesort() we now inform the handler of exactly which columns are needed
        doing the sort and choosing the rows.
      
      - The TABLE_SHARE object has a 'all_set' column bitmap one can use
        when one needs a column bitmap with all columns set.
        (This is used for table->use_all_columns() and other places)
      
      - The TABLE object has 3 column bitmaps:
        - def_read_set     Default bitmap for columns to be read
        - def_write_set    Default bitmap for columns to be written
        - tmp_set          Can be used as a temporary bitmap when needed.
        The table object has also two pointer to bitmaps read_set and write_set
        that the handler should use to find out which columns are used in which way.
      
      - count() optimization now calls handler::records() instead of using
        handler->stats.records (if (table_flags() & HA_HAS_RECORDS) is true).
      
      - Added extra argument to Item::walk() to indicate if we should also
        traverse sub queries.
      
      - Added TABLE parameter to cp_buffer_from_ref()
      
      - Don't close tables created with CREATE ... SELECT but keep them in
        the table cache. (Faster usage of newly created tables).
      
      
      New interfaces:
      
      - table->clear_column_bitmaps() to initialize the bitmaps for tables
        at start of new statements.
      
      - table->column_bitmaps_set() to set up new column bitmaps and signal
        the handler about this.
      
      - table->column_bitmaps_set_no_signal() for some few cases where we need
        to setup new column bitmaps but don't signal the handler (as the handler
        has already been signaled about these before). Used for the momement
        only in opt_range.cc when doing ROR scans.
      
      - table->use_all_columns() to install a bitmap where all columns are marked
        as use in the read and the write set.
      
      - table->default_column_bitmaps() to install the normal read and write
        column bitmaps, but not signaling the handler about this.
        This is mainly used when creating TABLE instances.
      
      - table->mark_columns_needed_for_delete(),
        table->mark_columns_needed_for_delete() and
        table->mark_columns_needed_for_insert() to allow us to put additional
        columns in column usage maps if handler so requires.
        (The handler indicates what it neads in handler->table_flags())
      
      - table->prepare_for_position() to allow us to tell handler that it
        needs to read primary key parts to be able to store them in
        future table->position() calls.
        (This replaces the table->file->ha_retrieve_all_pk function)
      
      - table->mark_auto_increment_column() to tell handler are going to update
        columns part of any auto_increment key.
      
      - table->mark_columns_used_by_index() to mark all columns that is part of
        an index.  It will also send extra(HA_EXTRA_KEYREAD) to handler to allow
        it to quickly know that it only needs to read colums that are part
        of the key.  (The handler can also use the column map for detecting this,
        but simpler/faster handler can just monitor the extra() call).
      
      - table->mark_columns_used_by_index_no_reset() to in addition to other columns,
        also mark all columns that is used by the given key.
      
      - table->restore_column_maps_after_mark_index() to restore to default
        column maps after a call to table->mark_columns_used_by_index().
      
      - New item function register_field_in_read_map(), for marking used columns
        in table->read_map. Used by filesort() to mark all used columns
      
      - Maintain in TABLE->merge_keys set of all keys that are used in query.
        (Simplices some optimization loops)
      
      - Maintain Field->part_of_key_not_clustered which is like Field->part_of_key
        but the field in the clustered key is not assumed to be part of all index.
        (used in opt_range.cc for faster loops)
      
      -  dbug_tmp_use_all_columns(), dbug_tmp_restore_column_map()
         tmp_use_all_columns() and tmp_restore_column_map() functions to temporally
         mark all columns as usable.  The 'dbug_' version is primarily intended
         inside a handler when it wants to just call Field:store() & Field::val()
         functions, but don't need the column maps set for any other usage.
         (ie:: bitmap_is_set() is never called)
      
      - We can't use compare_records() to skip updates for handlers that returns
        a partial column set and the read_set doesn't cover all columns in the
        write set. The reason for this is that if we have a column marked only for
        write we can't in the MySQL level know if the value changed or not.
        The reason this worked before was that MySQL marked all to be written
        columns as also to be read. The new 'optimal' bitmaps exposed this 'hidden
        bug'.
      
      - open_table_from_share() does not anymore setup temporary MEM_ROOT
        object as a thread specific variable for the handler. Instead we
        send the to-be-used MEMROOT to get_new_handler().
        (Simpler, faster code)
      
      
      
      Bugs fixed:
      
      - Column marking was not done correctly in a lot of cases.
        (ALTER TABLE, when using triggers, auto_increment fields etc)
        (Could potentially result in wrong values inserted in table handlers
        relying on that the old column maps or field->set_query_id was correct)
        Especially when it comes to triggers, there may be cases where the
        old code would cause lost/wrong values for NDB and/or InnoDB tables.
      
      - Split thd->options flag OPTION_STATUS_NO_TRANS_UPDATE to two flags:
        OPTION_STATUS_NO_TRANS_UPDATE and OPTION_KEEP_LOG.
        This allowed me to remove some wrong warnings about:
        "Some non-transactional changed tables couldn't be rolled back"
      
      - Fixed handling of INSERT .. SELECT and CREATE ... SELECT that wrongly reset
        (thd->options & OPTION_STATUS_NO_TRANS_UPDATE) which caused us to loose
        some warnings about
        "Some non-transactional changed tables couldn't be rolled back")
      
      - Fixed use of uninitialized memory in ha_ndbcluster.cc::delete_table()
        which could cause delete_table to report random failures.
      
      - Fixed core dumps for some tests when running with --debug
      
      - Added missing FN_LIBCHAR in mysql_rm_tmp_tables()
        (This has probably caused us to not properly remove temporary files after
        crash)
      
      - slow_logs was not properly initialized, which could maybe cause
        extra/lost entries in slow log.
      
      - If we get an duplicate row on insert, change column map to read and
        write all columns while retrying the operation. This is required by
        the definition of REPLACE and also ensures that fields that are only
        part of UPDATE are properly handled.  This fixed a bug in NDB and
        REPLACE where REPLACE wrongly copied some column values from the replaced
        row.
      
      - For table handler that doesn't support NULL in keys, we would give an error
        when creating a primary key with NULL fields, even after the fields has been
        automaticly converted to NOT NULL.
      
      - Creating a primary key on a SPATIAL key, would fail if field was not
        declared as NOT NULL.
      
      
      Cleanups:
      
      - Removed not used condition argument to setup_tables
      
      - Removed not needed item function reset_query_id_processor().
      
      - Field->add_index is removed. Now this is instead maintained in
        (field->flags & FIELD_IN_ADD_INDEX)
      
      - Field->fieldnr is removed (use field->field_index instead)
      
      - New argument to filesort() to indicate that it should return a set of
        row pointers (not used columns). This allowed me to remove some references
        to sql_command in filesort and should also enable us to return column
        results in some cases where we couldn't before.
      
      - Changed column bitmap handling in opt_range.cc to be aligned with TABLE
        bitmap, which allowed me to use bitmap functions instead of looping over
        all fields to create some needed bitmaps. (Faster and smaller code)
      
      - Broke up found too long lines
      
      - Moved some variable declaration at start of function for better code
        readability.
      
      - Removed some not used arguments from functions.
        (setup_fields(), mysql_prepare_insert_check_table())
      
      - setup_fields() now takes an enum instead of an int for marking columns
         usage.
      
      - For internal temporary tables, use handler::write_row(),
        handler::delete_row() and handler::update_row() instead of
        handler::ha_xxxx() for faster execution.
      
      - Changed some constants to enum's and define's.
      
      - Using separate column read and write sets allows for easier checking
        of timestamp field was set by statement.
      
      - Remove calls to free_io_cache() as this is now done automaticly in ha_reset()
      
      - Don't build table->normalized_path as this is now identical to table->path
        (after bar's fixes to convert filenames)
      
      - Fixed some missed DBUG_PRINT(.."%lx") to use "0x%lx" to make it easier to
        do comparision with the 'convert-dbug-for-diff' tool.
      
      
      Things left to do in 5.1:
      
      - We wrongly log failed CREATE TABLE ... SELECT in some cases when using
        row based logging (as shown by testcase binlog_row_mix_innodb_myisam.result)
        Mats has promised to look into this.
      
      - Test that my fix for CREATE TABLE ... SELECT is indeed correct.
        (I added several test cases for this, but in this case it's better that
        someone else also tests this throughly).
        Lars has promosed to do this.

      mysys/base64.c:
        Include my_global.h first
      mysys/my_bitmap.c:
        Added bitmap_is_overlapping(), bitmap_test_and_clear() and bitmap_copy()
        Changed logic of bitmap handling to be a bit more efficent (Did this together with Mikael Ronström)
        Now the 'extra, not used bits' in the bitmap are assumed to have a 'random value' and the bitmap functions are free to change them whenever needed.
        Changed how mutex is allocated to make 'bitmap_free()' function simpler.
      mysys/thr_lock.c:
        Added 0x before thread pointers (for easier comparison of DBUG traces)
      sql/event.cc:

        Don't print warning that event table is damaged if it doesn't exists.
      sql/field.cc:
        Added ASSERT_COLUMN_MARKED_FOR_WRITE in all store() methods and ASSERT_COLUMN_MARKED_FOR_READ in all val() methods to catch wrong setting if table->read_set and table->write_set
        (Rest of changes are only indentation cleanups)
      sql/field.h:

        This allowed me to remove checking of sql_command.
        Create a temporary column bitmap for fields that are used by the sorting process.
        Use column bitmaps instead of query_id
      sql/ha_berkeley.cc:

        Use 'simpler to use' XXXX_LEN' macros
        A bit simpler logic in ::write_row() when creating statements.
        In update, only include test of fields actually read.
        (This greatly simplifies the queries sent by the federated engine)
        Similar changes done for delete_row()
      sql/ha_federated.h:
        Update to 'newer' table handler interface
        Changed XXX_LEN macros to use sizeof(...)-1, to simplify usage in ha_federated.cc

        - Added ::reset(), with code from ::extra(HA_EXTRA_RESET)
        - Removed HA_EXTRA_RETRIVE_ALL_COLS and HA_EXTRA_RETRIEVE_PRIMARY_KEY as
          the table->read_set and table->write_set bitmaps now are accurate
      sql/ha_innodb.h:
        Update to 'newer' table handler interface
        - table_flags are now ulonglong
        - Added reset() method
        - Removed not needed ha_retrieve_all_cols() and ha_retrieve_all_pk() columns.
        - Made build_template() a class function to be able to easier access class variables

        In ::complemented_read() we have to check both the read and write bitmap as the old code did mark all changed columns also in the read map
        Correct dumping of field data with DBUG_DUMP
        Prefix addresses in DBUG_PRINT with 0x
        Fixed usage of not initialized memory
        Update to use field->flags & FIELD_IN_ADD_INDEX instead of field->add_index.
      sql/ha_ndbcluster.h:
        Update to 'newer' table handler interface
      sql/ha_ndbcluster_binlog.cc:
        Mark usage of all columns in ndbcluster binlog tables
        false -> FALSE, true -> TRUE
        Use table->s->all_set instead of creating a temporary bitmap.
      sql/ha_partition.cc:
        Update to 'newer' table handler interface
        Added memroot to initialise_partitions() and related functions to get faster memory allocation.
        partition_create_handler() is now responsible for initialisation of the partition object
        Some trivial optimizations and indentation fixes
        Ensure that table_flags() are up to date
        Removed documentation for removed HA_EXTRA flags
        Fixed 'strange' usage of m_file[i] in new_handlers_from_part_info()that worked in current code 'by chance'
      sql/ha_partition.h:
        Update to 'newer' table handler interface
      sql/handler.cc:
        create_xxx handler now takes MEMROOT as an argument to simplify memory allocation.
        Much simpler get_new_handler()
        (Initialization of the object is now handled by the create method for the engine)
        Moved all allocation of bitmap handling to the TABLE object (in table.cc)
        Added column_bitmaps_signal() to signal column usage changes.
        Changed binlog_log_row() to use the exiusting all_set bitmap in the table object.
        Added ha_reset() function to test that the file object is ok at end of statement and call handler::reset()
        Added use_hidden_primary_key() to signal handler that we we are going to read and update + delete the row and the handler should thus remember the position for the row
      sql/handler.h:
        Added HA_NO_TRANSACTIONS, HA_PARTIAL_COLUMN_READ, HA_REQUIRES_KEY_COLUMNS_FOR_DELETE,HA_PRIMARY_KEY_REQUIRED_FOR_DELETE and HA_HAS_RECORDS
        Removed HA_NOT_EXACT_COUNT, HA_READ_RND_SAME

        HA_NOT_EXACT_COUNT replaced by HA_STATS_RECORDS_IS_EXACT, HA_HAS_RECORDS and records()
        HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS renamed to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION
        Added future row type 'ROW_TYPE_PAGES'
        Added MEM_ROOT to handlerton 'create' function
        Added ha_statistics, a structure for all status variable in the base handler class.
        Moved all status variables in the handler class into a stats structs to improve readability.
        ha_table_flags() is now a cached (not virtual) version of table_flags()
        reset() doesn't anymore call extra(HA_EXTRA_RESET) but is a function of it's own.
        Renamed dupp_ref to dup_ref
        Renamed not used handler::sortkey
        Moved read_set and write_set to TABLE structure
        handler::init() function added for cacheing of virtual constants from engine.
      sql/item.cc:
        Added register_field_in_read_map() for marking used columns in expression.
        This is used by filesort() for creating an optimal column bitmap while retrieving columns for sorting.
        Initalize value.cs_info.character_set_client to fix core dump bug with --debug
        set_query_id -> mark_used_columns
        Mark used columns in read_set OR write_set.
      sql/item.h:
        Removed reset_query_id_processor() as it's not needed anymore.
        Added register_field_in_read_map()

        traverse sub queries.
      sql/item_cmpfunc.cc:
        Temporary mark used columns to be read/writable
        Update Item::walk to new interface
      sql/item_cmpfunc.h:
        Added extra argument to Item::walk() to indicate if we should also traverse sub queries.
      sql/item_func.cc:
        Update Item::walk() to new interface
        table_flags() -> ha_table_flags()
      sql/item_func.h:
        Update Item::walk() to new interface
      sql/item_row.cc:
        Update Item::walk() to new interface
      sql/item_row.h:
        Update Item::walk() to new interface
      sql/item_strfunc.h:
        Update Item::walk() to new interface
      sql/item_subselect.cc:
        Added Item_subselect::walk()
        (It was a bug it was missing before. Not sure what kind of bugs this could have caused)

        Update Item::walk() to new interface
      sql/item_sum.cc:
        Update Item::walk() to new interface

      sql/item_sum.h:
        Update Item::walk() to new interface
      sql/key.cc:
        Updates for new handler interace
      sql/log.cc:
        Mark all columns used for log tables
        Split options flag
        Ensured that second argument to trans_register_ha is a bool
      sql/log_event.cc:
        Fixed comments to be withing 79 characters
        Use OPTION_KEEP_LOG instead of OPTION_STATUS_NO_TRANS_UPDATE to remove wrong warnings
        Updates for new handler interface
        Use 0x%lx instead of %p (portability problem)
      sql/mysql_priv.h:
        Added OPTION_KEEP_LOG to indicate that we should replicate the binlog even on rollback
        Removed not used 'conds' argument to setup_tables
      sql/mysqld.cc:
        Indentation fixes and removed old comment
      sql/opt_range.cc:
        Update to new handler and bitmap interface.
        Fixed calls to cp_buffer_from_ref() and walk() (new argument).
        Create new temporary bitmaps for ror scans.
        (Needed because of handler changes and to get more accurate column bitmaps than before)
        Remove not needed file->ha_reset() call before file->close().
        Some trivial optimization and indentation fixes.
        Use Field->part_of_key_not_clustered() to check if field is part of a key, instead of looping over all key parts.
        
        Added flag 'in_ror_merged_scan' to allow ::get_next() to know that we need a special column bitmap to only fetch pointer to record.
        This is needed because ror scan uses the same TABLE object but different file objects, which creates problem for the column bitmap handling.
        (This is a temporary solution. A better one would be to allocate an own TABLE object for ROR scans)
        
        Optimized bitmap handling in ror scans:
        - Start bitmap at position 0, not 1
        - Use same bitmap size as in TABLE
        - Use table->read_set and table->write_set to create column bitmaps instead of looping over all fields in table
      sql/opt_range.h:
        Added 'in_ror_merged_scan' to indicate if we are doing a ROR scan
        Added temporary column bitmaps used in ROR scans
      sql/opt_sum.cc:
        Added get_ext_record_count() which is used in COUNT() optimization if handler has HA_HAS_RECORDS
        Note that we don't call this if handler has HA_STATS_RECORDS_IS_EXACT set.
      sql/protocol.cc:
        We need to mark columns as readable in ::store() as we sometimes return default value for fields to the user
      sql/records.cc:
        Updates for new handler interface
      sql/set_var.cc:
        Handle splitting OPTION_STATUS_NO_TRANS_UPDATE to two flags
      sql/share/errmsg.txt:
        Fixed wrong
      sql/sp.cc:
        Mark that we are using all columns for the proc table
        Update call to setup_tables() to use new prototype
      sql/sp_head.cc:
        Removed QQ comment
      sql/spatial.cc:
        Removed wrong QQ comment
      sql/sql_acl.cc:
        Mark that we need all columns for acl tables
        Supply memroot to some 'new' calls.
        Indentation fixes
      sql/sql_base.cc:
        set_query_id removed
        Ensure we call ha_reset() at end of each statement
        Mark read columns in read_set and changed columns in write_set (Before all columns was marked in read set)
        Fixed marking of some columns that was not proplerly marked before
        Maintain in TABLE->merge_keys set of all keys that are used in some way
        Removed not used 'conds' argument from setup_tables()
        Remove not used setting of 'dupp_field' in insert_fields()
        Added missing FN_LIBCHAR in mysql_rm_tmp_tables()
        (This has probably caused us to not properly remove temporary files after crash)
      sql/sql_bitmap.h:
        Added is_overlapping()
      sql/sql_class.cc:
        Slow_logs was not properly initialized, which could maybe cause extra/lost entries in slow log.
        set_query_id -> mark_used_columns
        Simpler variable usage in pack_row()  (cleanup)
        Moved some variable declartion at start of function for better code readability
      sql/sql_class.h:
        Added enum_mark_columns
        Updated comments
        Renamed dupp_field -> dup_field
        Added virtual function 'can_rollback_data()' to select_insert() to be used in CREATE ... SELECT to optimize use of OPTION_STATUS_NO_TRANS_UPDATE.
        (This fixes a bug in CREATE ... SELECT where we did give wrong warnings when using non transacational tables)
      sql/sql_delete.cc:
        Updates to new handler interface
        Call table->mark_columns_needed_for_delete() to allow us to put additional columns in column usage maps if handler so requires.
        Call table->prepare_for_position() to tell handler that we are going to call ha_position().
        Removed call to free_io_cache(). (io_cache is now removed in ha_reset()).
        Fixed calls to setup_tables()
      sql/sql_do.cc:
        Update call to setup_fields()
      sql/sql_handler.cc:
        Tell handler tables to always read all columns.
        Use temporary column map when storing value in field for later index usage
      sql/sql_help.cc:
        Makr all used fields to be read
        Update call to setup_fields()
      sql/sql_insert.cc:
        Tell handler we are going to update the auto_increment column
        dupp_field -> dup_field
        Set column usage bits for timestamp field.
        Call table->mark_columns_needed_for_insert() and table->mark_auto_increment_column()
        Removed not used argument from mysql_prepare_insert_check_table().
        
        If we get an duplicate row on insert, change column map to read and write all columns while retrying the operatation.
        This is required by the definition of REPLACE and also ensures that fields that are only part of UPDATE are properly handled.
        This fixed a bug in NDB and REPLACE where REPLACE wrongly copied some column values from the replaced row.
        
        Setup new bitmaps for delayed insert rows
        Remove reseting of next_number_fields as it will be reset on next call to handler_insert()
        
        Fixed usage of thd->options and OPTION_STATUS_NO_TRANS_UPDATE.
        The issue was that one should not to reset this flag as it may be set by a previous statement.
        The way it was now used caused us to loose some warnings and get other wrong warnings when using non transactional tables mixed with transactional.
        I fixed it by introducing 'select_insert::can_rollback_data' to inform send_error() that the given statement can be rolled back (which in case of CREATE TABLE can always be done)
        Don't close tables created with CREATE ... SELECT but keep them in the table cache.
        
        Moved out MY_HOOKS from inside function (better readability)
      sql/sql_load.cc:
        Update to use new handler and column marking interface
        Update using setup_tables()
      sql/sql_olap.cc:
        Update calls to setup_tables
        Use enums instead of constants to setup_fields()
      sql/sql_parse.cc:
        Handle OPTION_KEEP_LOG:
        - Set it on CREATE TEMPORARY TABLE / DROP TABLE
        - Reset it when OPTION_STATUS_NO_TRANS_UPDATE is reset
        - Don't set it for CREATE ... SELECT (this is handled in select_create class)
        Remove reseting of OPTION_STATUS_NO_TRANS_UPDATE in begin_trans() as this should already be reset.
        If in autocommit mode, reset OPTION_KEEP_LOG and OPTION_STATUS_NO_TRANS_UPDATE to not give warnings in future commands
      sql/sql_partition.cc:
        Update walk() usage
        Trivial indentation fixes
      sql/sql_plugin.cc:
        Mark all columns as used for plugins
      sql/sql_prepare.cc:

        Updates for new handler interface
        Update calls to setup_fields()
      sql/sql_repl.cc:
        Indentation fixes
      sql/sql_select.cc:
        Update call to setup_tables() and setup_fields()
        Remove some old disabled code
        Update to new hadler interface
        Indentation cleanups
        Added column bitmaps for temporary tables.
        Remove updating of the removed slots in the Field class
        Added TABLE argument to cp_buffer_from_ref() (To be able to install temporary column maps)
        For internal temporary tables, use handler::write_row(), handler::delete_row() and handler::update_row() instead of handler::ha_xxxx() for faster execution.
      sql/sql_select.h:
        Indentaition fixes.
        Install temporary column usage maps when needed
        Added TABLE element to cp_buffer_from_ref()
      sql/sql_show.cc:
        Update to new handler interface
        Mark all columns used for internal tables.
        Style fixes.
        Added support for 'future' ROW_TYPE_PAGES.
        Don't allocate TMP_TABLE_PARAM with calloc. The 'init()' function will initialize the structure properly.
      sql/sql_table.cc:
        Update to new handler interface
        Simple my_snprintf -> strmake()
        Changed some constants to defines
        Don't test for NULL in primary key (as we a couple of line above force the PRIMARY KEY to be NOT NULL)
        Change field->add_index to use field->flags & FIELD_IN_ADD_INDEX
        Mark all columns as used for ALTER TABLE
        Style fixes
        Update call to filesort()
      sql/sql_trigger.h:
        Added friend functions to be able to test if triggers exists for table we are going to insert/update or delete in.
      sql/sql_udf.cc:
        Mark all columns as used for udf system table.
      sql/sql_union.cc:
        Update call to walk()
        Update to new handler interface
      sql/sql_update.cc:
        Remove query_id argument from compare_record()
        Use column bitmaps instead of query_id.
        We can't use compare_records() to skip updates for handlers that returns a partial column set and the read_set doesn't cover all columns in the write set, because compare_record() can't in this case know if a not read column changed value.
        Update call to setup_fields()
        Using separate column read and write sets allows for easier checking of timestamp field was set by statement.
        Removed call to free_io_cache() as this is now done in ha_reset()
        Call table->mark_columns_needed_for_update() and table->prepare_for_position()
        Style fixes
      sql/sql_view.cc:
        Style fixes

        Create column bitmaps in TABLE and TABLE_SHARE
        Don't setup a temporary MEM_ROOT object as a thread specific variable for the handler. Instead we send the to-be-used MEMROOT to get_new_handler()
        Update to new handler interface
        Update call to walk()
        Added new functions:
        - st_table::clear_column_bitmaps()
        - st_table::prepare_for_position()
        - st_table::mark_columns_used_by_index()

        - st_table::mark_columns_needed_for_update()
        - st_table::mark_columns_needed_for_insert()
      sql/table.h:
        Moved column usage bitmaps from handler to TABLE
        Added to TABLE_SHARE all_set and column_bitmap_size
        Added to TABLE merge_keys, bitmap_init_values, def_read_set, def_write_set, tmp_set, read_set and write_set.
        Declared all new table column bitmap functions
        Added TABLE functions column_bitmaps_set(), column_bitmaps_set_no_signal(), use_all_columns() and default_column_bitmaps()
        Added functions: tmp_use_all_columns() and tmp_restore_column_map() to temporarly switch column bitmaps
        Added functions: dbug_tmp_use_all_columns() and dbug_tmp_restore_column_map() to temporarly switch column bitmaps to avoid asserts in Field::store() and Field::val().
      sql/tztime.cc:
        Mark all columns as used for timezone tables

        Fixed DBUG_PRINT messages to use 0x%lx instead of %lx
      storage/myisam/mi_test2.c:
        Use mi_reset()
      storage/myisam/myisampack.c:

      Bug#19066 (DELETE FROM inconsistency for NDB): · ddc25698
      unknown authored
      Under row-based replication, DELETE FROM will now always be
      replicated as individual row deletions, while TRUNCATE TABLE will
      always be replicated as a statement.

      Bug#17377 Federated Engine returns wrong Data, always the rows with the highest ID · 701b6991
      unknown authored
       - Always make rnd_pos reposition the cursor in the fetched result set.
      
      
      mysql-test/r/federated.result:
        Update test result
      mysql-test/t/federated.test:
        Add test for bug#17377
      sql/ha_federated.cc:
        Remove the "scan_flag" variable. rnd_pos should always move to a new position in the result set. 
        The "scan" flag in rnd_init will protect from the old result set being 
        closed and a new fecthed. I think the "scan_flag" was added before check of the "scan" argument in rnd_init was added.
      sql/ha_federated.h:
        Remove class variable "scan_flag"

      deallocation cleanup
      
      
      mysql-test/r/federated.result:
        new test results
      mysql-test/t/federated.test:
        New tests, and added explains per Timour's suggestion. This will keep
                track of whether changes have been made to the optimiser that might affect
                Federated.
                Also changed the error codes to federated error codes in the error tests
      sql/ha_federated.cc:
        1. Not using MAX_REMOTE_SIZE, so removed
                 2. Changed all defines that were IO_SIZE to FEDERATED_QUERY_BUFFER_SIZE
                 3. Now using Federated Error Codes
                 4. Implemented ::info (gets valid 'records' number)
                 5. Implemented ::read_range_first - now uses indexes in range operations
                 6. Better allocation in get_share
                 7. Cleaned up memory bug in get_share
                 8. Better initial query "SELECT * FROM t1 WHERE 1=0" for check_foreign_data_src
                 9. emit_key_part_name and emit_key_part_element for read_range_first to not
                    have redundancy
                 10. Made sure all 'append's pass length, and use append("") to ensure proper
                     null termination of strings being built.
                 11. Better message creation. If ER_QUERY_ON_FOREIGN_DATA_SRC, I also pass
                     the actual error code and message from the foreign data src.
                 12. Cleaned up how the result set and share->scheme is freed.
      sql/share/errmsg.txt:
        New Federated error messages that are more tailored to the type of information
        we want to see when federated has an error.
      mysql-test/include/federated.inc:
        New bitkeeper file, include file for separating setup from main test suite
      mysql-test/include/federated_cleanup.inc:
        New BitKeeper file ``mysql-test/include/federated_cleanup.inc''
      sql/ha_federated.h:
        Added comments where needed, one was already commented about

      changes to fix joins not working (bug #10848). New tests, as well as table->status being set in index_read_idx
      
      
      mysql-test/r/federated.result:
        new join test results
      mysql-test/t/federated.test:
        new simple join tests (more to come with subsequent commits)
      sql/ha_federated.cc:
        This fixes joins not working. Monty discussed that having to deal 
        with table->status needs to be moved from the handler/storage engine
        to a higher level

      WL #2094 Federated Storage Engine · 24dc8331
      unknown authored
      Changes to a test with a update to a table with 1001 columns, the last being a blob. 
      On HP, the test worked properly, but on other OSs, there's a problem with using the 
      blob column in an update where clause. The field method val_string(String *, char *) 
      should work, but doesn't seem to deal with blobd, and for some reason, cannot get
      the correct value of the blob column from the byte pointer in update_row, "*old_data"
      which is a byte pointer to the row in mysql format, that will be replaced with 
      "*new_data" (which conveniently has a field pointer to use to get values from).
      
      Will document this.
      
      
      mysql-test/r/federated.result:
        New test results. These results have been tested on production and hpita2 successfully.
      mysql-test/t/federated.test:
        Changed blob column in this test due to some issues with HPUX handling it correctly
        and other OSs not. Will document this (blobs in update where clause)

      Patch #2, all coding style changes per Kostja's review 
      (as requested to keep style changes separate from functionality changes),
      as well as changes to the test suit to no longer use hard-coded port 
      values in foreign table creation statement
      
      
      mysql-test/r/federated.result:
        Now using SLAVE_PORT as opposed to hard-coded port value
      mysql-test/t/federated.test:
        - changed test to use SLAVE_MYPORT
        - made all standard SQL uppercase
        - made test 80 cols, except blob inserts of text
      sql/ha_federated.cc:
        - made sure all comments and style changes were according to Kostja's 
        review 
        - combined parse_url error handling into a 'error:' block, took out 
        triple exclamation points.
        - clarified commented documentation
        - got rid of all trailing spaces

      This patch contains all that my previous patch (1.1814) contained, with the addition of using cli_fetch_lengths for
      handling binary data (Bar noted this on the review of 1.1814, Guilhem suggested using cli_fetch_lenghts by 
      making available via removal of static in method definition and declaration in mysql.h, but
      Konstantin had some reservations, but he said to commit the patch using this anyway,
      and I suppose this can be discussed. I abandoned 1.1814 because Monty made a couple
      fixes to my code as well as formatting changes, and I thought it would just be easier
      to hand-edit my changes into a fresh clone and then make a patch. 
      
      The reason for using cli_fetch_lengths is so that I can correctly get the length of
      the field I am setting into the field. I was previously using 'strlen' but Bar pointed out this
      won't correctly get the length of binary data and is also less effecient. Upon testing,
      it was in fact verified that binary data in a blob table was being inserted correctly,
      but not being retrieved correctly, all due to not having the correct value for the
      field:
      
      (*field)->store(row[x], strlen(row[x]), &my_charset_bin);
      
      was changed to:
      
      (*field)->store(row[x], lengths[x], &my_charset_bin);
      
      lengths being a unsigned long pointer to the values of the field lengths from a 
      MYSQL_ROW.
      
      Since the server doesn't have the function "mysql_fetch_lengths" available, I tried 
      to use "result->lengths", but this isn't set, so I finally successfully used 
      cli_fetch_lenghts, which does give the correct lengths, and now the binary data gets
      retrieved correctly.
      
      I've also run the code through indent-ex and am using Brian's vimrc to ensure correct formatting!
      
      This code passes the entire test suite, without any errors or warning on both my 
      workstation and build.mysql.com
      
      
      include/mysql.h:
        added cli_fetch_lengths to mysql.h in order to use this function in the federated handler
      mysql-test/r/federated.result:
        - Moved countries to be created and inserted prior to federated test table
        - Added a test of inserting binary values into a blob table
      mysql-test/t/federated.test:
        - Moved order of countries table creation to prior to test table creation
        - Test insertion of binary values in a blob table
      sql-common/client.c:
        removed 'static' to allow cli_fetch_lengths to be used in the federated handler
      sql/ha_federated.cc:
        1. share->scheme that was created in parse_url was not being freed
        2. HASH federated_open_tables was being deleted, but not freed
        3. 'result' from mysql_store_result was not being free in several instances
        4. Fixed the problem where a table scan was being performed after
        index_read_idx, which didn't cause a problem because the result set from
        idx_read_idx was not being freed, but once the result set was properly freed,
        it broke update_row. Now, I'm using the bool 'scan' to determine if I need to
        perform a table scan, which it magically is false when the query is an update
        with an index.
        5. Changed all stings containing the query to perform in mysql_real_query
        calls from string.c_ptr_quick() to string.ptr() per Monty's suggestion
        (better performance)
        6. Fixed various cast/type/truth compile warnings.
        7. Removed 'load_conn_info' and just let 'parse_url' handle it.
        8. Added the use of cli_fetch_lengths, needed to fix binary values being retrieved 
        from the database in rnd_next/convert_row_to_internal_format
        9. Formatting changes by using indent-ex!
      sql/ha_federated.h:
        added scan flag, setting defaults for result and scan_flag
