      WL#3464: Add replication event to denote gap in replication · adaf162b
      unknown authored
      Adding an event that can be used to denote that an incident occured
      on the master. The event can be used to denote a gap in the replication
      stream, but can also be used to denote other incidents.
      
      In addition, the injector interface is extended with functions to
      generate an incident event. The function will also rotate the binary
      log after generating an incident event to get a fresh binary log.

      Bug#17642 mysqlbinlog: Restore from row-based binlog fails · e653222d
      unknown authored
      Problem: mysqlbinlog_base64 failed sporadically.
      
      Reason: Missing "flush logs" before running $MYSQL_BINLOG,
      which could start dumping the log file before server
      has finished writting into it.
      Fix:
      - implementing --force-if-open option to "mysqlbinlog"
      - adding --disable-force-if-open to make $MYSQL_BINLOG
        fail on non-closed log files, to garantee that nobody
        will forget "flush logs" in the future.
      - adding "flush logs" into all affected tests.
      
      
      client/mysqlbinlog.cc:
        Implementing --force-if-open option with TRUE by default
      mysql-test/mysql-test-run.pl:

        Adding new tests:
        - checking that $MYSQL_BINLOG returns an error on a non-closed binlog
        file because of --disable-force-if-open
        - checking that it does not return an error with --force-if-open

      fixes after merge. Updates to test's results. · 20c59f9c
      unknown authored
      We now reset the THD members related to auto_increment+binlog in
      MYSQL_LOG::write(). This is better than in THD::cleanup_after_query(),
      which was not able to distinguish between SELECT myfunc1(),myfunc2()
      and INSERT INTO t SELECT myfunc1(),myfunc2() from a binlogging point
      of view.
      Rows_log_event::exec_event() now calls lex_start() instead of
      mysql_init_query() because the latter now does too much (it resets
      the binlog format).

        if the size of an event changes).
      mysql-test/r/rpl_insert_id.result:
        fix after merge
      mysql-test/r/rpl_loaddata.result:
        The binlog positions change, because one event disappeared; indeed there
        was this in the binlog (in the current 5.1!):
        SET INSERT_ID=2;
        SET INSERT_ID=1;
        SET TIMESTAMP=1152540671;
        load data LOCAL INFILE '/tmp/SQL_LOAD_MB-1-2' INTO table t1;
        Two INSERT_ID events, useless and a bug. Goes away afer cleaning up
        auto_increment handling.
      mysql-test/r/rpl_switch_stm_row_mixed.result:
        INSERT_ID=5 appears, it's a consequence of having merged the fix
        for BUG#20341
        "stored function inserting into one auto_increment puts bad data in slave".
        In mixed mode, if one substatement of a stored procedure requires row-based,
        the entire procedure uses row-based (was already true for stored functions);
        this is a consequence of not doing the resetting of binlog format inside
        lock_tables() (which didn't work with how the slave thread executes
        row-based binlog events).
      mysql-test/t/rpl_switch_stm_row_mixed.test:
        removing the multi-row delayed insert because in RBR the number of events
        which it generates, is not repeatable (probably depends on how the delayed
        thread groups rows, i.e. dependent on timing).
      sql/ha_partition.cc:
        update to new prototype
      sql/ha_partition.h:
        update to new prototype of the handler:: method.
      sql/handler.cc:
        after-merge fixes (manually merging part which was hard to merge in fmtool)
      sql/log.cc:
        When we write to the binary log, THD's parameters which influenced this
        write are reset: stmt_depends_on_first_successful_insert_id_in_prev_stmt
        and auto_inc_intervals_in_cur_stmt_for_binlog. This is so that future
        writes are not influenced by those and can write their own values.
        As a consequence, when we don't write to the binlog we do not reset.
        This is to abide by the rule that in a complex statement (using triggers etc),
        the first top- or substatement to generate auto_increment ids
        wins their writing to the binlog (that writing may be done by the statement
        itself or by the caller); so for example for
        INSERT INTO t SELECT myfunc() where myfunc() inserts into auto_increment
        and INSERT INTO t does not, myfunc() will fill
        auto_inc_intervals_in_cur_stmt_for_binlog, which will not be reset when
        myfunc() ends, then INSERT INTO t will write to the binlog and thus
        write the preserved auto_inc_intervals_in_cur_stmt_for_binlog.
      sql/log_event.cc:
        mysql_init_query() does too much now to be called in Rows_log_event::exec_event
        (it call mysql_reset_thd_for_next_command() which may switch
        the binlog format now).
        It's ok to call it in Table_map_log_event::exec_event() but its call must
        be before setting the binlog format to "row".
      sql/sql_base.cc:
        Resetting the binlog format in lock_tables() was a bad idea of mine;
        it causes problems in execution of row-based binlog events, where
        the thread sets the binlog format by itself and does not want a next
        lock_tables() to reset the binlog format.
        It is also misleading, for a function named lock_tables(), to reset
        the binlog format.
        As a consequence of this change, in mixed binlogging mode, a routine
        is logged either entirely statement-based or entirely row-based, we
        don't switch in the middle (this was already true for prelocked routines,
        now it's also true for stored procedures).
      sql/sql_class.cc:
        resetting of auto_increment variables used for binlogging is now done
        when writing to the binary log, no need to do the resetting at the end
        of the statement. It is also more correct this way; consider
        SELECT myfunc1(),myfunc2();
        where both functions insert into the same auto_increment column.
        Binlogging is done in 2 events: "SELECT myfunc1()" and "SELECT myfunc2()".
        So each of those needs to have, in binlog, the INSERT_ID which
        it inserted. But as the 2 function calls are executed under prelocked mode,
        the old code didn't reset auto_inc_intervals_in_cur_stmt_for_binlog
        after the first SELECT was binlogged, and so the INSERT_ID of the first
        SELECT was binlogged for the first SELECT and (wrong) also for the 2nd
        SELECT event.
        stmt_depends_on_first_... has the same logic.
      sql/sql_class.h:
        clearer comment
      sql/sql_delete.cc:
        unneeded #ifdef. As we temporarily change the binlog format to "statement"
        before calling mysql_delete(), we must restore it afterwards.
      sql/sql_insert.cc:
        after-merge fixes.
        No need to reset auto_inc_intervals_in_cur_stmt_for_binlog for every
        row in the delayed insert system thread, because we already reset it
        when writing to the binlog.
      sql/sql_parse.cc:
        unneeded #ifdef

      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.

      mysql-test/t/view_grant.test:
        Drop used views
      mysql-test/valgrind.supp:
        Added supression of not needed warnings when printing stack trace
      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:
        Ensure 'use_all_columns()' is used for event tables
        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:
        Removed Field->query_id (replaced by table->read_set and table->write_set)
        Removed Field->fieldnr (use Field->field_index instead)
        Removed Field->add_index (Use Field->flags instead)
        Add Field->part_of_key_not_clustered (for usage in opt_range.cc)
      sql/filesort.cc:
        Added paramater sort_postion to filesort() to force sorting by position instead of storing all fields in the result set.
        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:
        Update to 'newer' table handler interface
      sql/ha_berkeley.h:
        Update to 'newer' table handler interface

        Update to 'newer' table handler interface
        Only read columns that are needed from remote server.
        In case of eq ranges, don't generate two conditions in the WHERE clause
        (this can still be optimized, but would require a bigger code change)
        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

      sql/ha_heap.cc:
        Update to 'newer' table handler interface
      sql/ha_heap.h:
        Update to 'newer' table handler interface

        - Renamed HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION.
        - Prefixed base status variables with 'stats'
        - Use table column bitmaps instead of ha_get_bit_in_read_set()
        - 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
      sql/ha_myisam.cc:
        Update to 'newer' table handler interface
      sql/ha_myisam.h:

      sql/ha_ndbcluster.cc:
        Update to 'newer' table handler interface
        Fixed use_blob_value() to be accurate
        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

        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()
        Added extra argument to Item::walk() to indicate if we should also
        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)
      sql/item_subselect.h:
        Update Item::walk() to new interface
      sql/item_sum.cc:
        Update Item::walk() to new interface
        Updates for new handler interace
      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:
        Added assert to find out hidden bugs in character_set_client (got an error in debug binary when this not set correctly)
        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
      sql/table.cc:
        Remove implicitely include 'errno.h'
        Remove code for building normalized path, as this is now identical to 'path'
        Remove field->fieldnr
        Added update of field->part_of_key_not_clustered()
        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::restore_column_maps_after_mark_index()
        - st_table::mark_columns_used_by_index_no_reset()
        - st_table::mark_auto_increment_column()
        - st_table::mark_columns_needed_for_delete()
        - 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
      storage/archive/ha_archive.cc:
        Update to new handler interface

        Update to new handler interface
