      Fixed bug#12185: Data type aggregation may produce wrong result · 35209c68
      unknown authored
      The Item::tmp_table_field_from_field_type() function creates Field_datetime
      object instead of Field_timestamp object for timestamp field thus always
      changing data type is a tmp table is used.
      
      The Field_blob object constructor which is used in the 
      Item::tmp_table_field_from_field_type() is always setting packlength field of
      newly created blob to 4. This leads to changing fields data type for example
      from the blob to the longblob if a temporary table is used.
      
      The Item::make_string_field() function always converts Field_string objects 
      to Field_varstring objects. This leads to changing data type from the 
      char/binary to varchar/varbinary.
      
      Added appropriate Field_timestamp object constructor for using in the 
      Item::tmp_table_field_from_field_type() function.
      
      Added Field_blob object constructor which sets pack length according to
      max_length argument.
      
      The Item::tmp_table_field_from_field_type() function now creates
      Field_timestamp object for a timestamp field.
      
      The Item_type_holder::display_length() now returns correct NULL length NULL
      length. 
      
      The Item::make_string_field() function now doesn't change Field_string to
      Field_varstring in the case of Item_type_holder. 
      
      The Item::tmp_table_field_from_field_type() function now uses the Field_blob
      constructor which sets packlength according to max_length.

      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.

      Bug#16218 - Crash on insert delayed · ab5ebc0f

      Bug#17294 - INSERT DELAYED puting an \n before data
      Bug#16611 - INSERT DELAYED corrupts data
      Bug#13707 - Server crash with INSERT DELAYED on MyISAM table
      Combined as Bug#16218.
      
      INSERT DELAYED crashed in 5.0 on a table with a varchar that 
      could be NULL and was created pre-5.0 (Bugs 16218 and 13707).
      INSERT DELAYED corrupted data in 5.0 on a table with varchar 
      fields that was created pre-5.0 (Bugs 17294 and 16611).
      
      In case of INSERT DELAYED the open table is copied from the
      delayed insert thread to be able to create a record for the 
      queue. When copying the fields, a method was used that did 
      convert old varchar to new varchar fields and did not set up 
      some pointers into the record buffer of the table.
      
      The field conversion was guilty for the misinterpretation of 
      the record contents by the delayed insert thread. The wrong
      pointer setup was guilty for the crashes.
      
      For Bug 13707 (Server crash with INSERT DELAYED on MyISAM table)
      I fixed the above mentioned method to set up one of the pointers.
      For Bug 16218 I set up the other pointers too.
      
      But when looking at the corruptions I got aware that converting
      the field type was totally wrong for INSERT DELAYED. The copied
      table is used to create a record that is to be sent to the
      delayed insert thread. Of course it can interpret the record
      correctly only if all field types are the same in both table
      objects.
      
      So I revoked the fix for Bug 13707 and changed the new_field() 
      method so that it can suppress conversions.
      
      No test case as this is a migration problem. One needs to
      create a table with 4.x and use it with 5.x. I added two
      test scripts to the bug report.

        I solved all four bugs in sql/sql_insert.cc by making exact

        Used the new parameter 'keep_type' of Field::new_field()
        to avoid field type conversion. The table copy must have
        exactly the same types of fields as the original table.
        Otherwise the record contents created by the foreground 
        thread could be misinterpreted by the delayed insert thread.

      This bug in Field_string::cmp resulted in a wrong comparison

      Given field a is declared as a varchar(16) collate utf8_unicode_ci
      INDEX(a(4)) gives us an example of such an index.
        
      Wrong key comparisons could lead to wrong result sets if

      Bug#20086: Can't get data from key partitioned tables with VARCHAR key · 4e138572
      unknown authored
      The problem appeared because the same values produced different hash
      during INSERT and SELECT for VARCHAR data type.
      Fix:
      VARCHAR required special treatment to avoid hashing of length bytes
      (leftmost one or two bytes) as well as trailing bytes beyond real length,
      which could contain garbage. Fix is done by introducing hash() - new method
      in the Field class.

      Fixed bug#16377: result of DATE/TIME functions were compared as strings which · 47311e8e
      unknown authored
      can lead to a wrong result.
      
      All date/time functions has the STRING result type thus their results are
      compared as strings. The string date representation allows a user to skip 
      some of leading zeros. This can lead to wrong comparison result if a date/time 
      function result is compared to such a string constant.
      
      The idea behind this bug fix is to compare results of date/time functions
      and data/time constants as ints, because that date/time representation is 
      more exact. To achieve this the agg_cmp_type() is changed to take in the
      account that a date/time field or an date/time item should be compared 
      as ints.
      
      This bug fix is partially back ported from 5.0.
      
      The agg_cmp_type() function now accepts THD as one of parameters. 
      In addition, it now checks if a date/time field/function is present in the
      list. If so, it tries to coerce all constants to INT to make date/time
      comparison return correct result. The field for the constant coercion is
      taken from the Item_field or constructed from the Item_func. In latter case
      the constructed field will be freed after conversion of all constant items.
      Otherwise the result is same as before - aggregated with help of the
      item_cmp_type() function.
      
      From the Item_func_between::fix_length_and_dec() function removed the part
      which was converting date/time constants to int if possible. Now this is 
      done by the agg_cmp_type() function.
      
      The new function result_as_longlong() is added to the Item class. 
      It indicates that the item is a date/time item and result of it can be
      compared as int. Such items are date/time fields/functions.
      
      Correct val_int() methods are implemented for classes Item_date_typecast, 
      Item_func_makedate, Item_time_typecast, Item_datetime_typecast. All these
      classes are derived from Item_str_func and Item_str_func::val_int() converts
      its string value to int without regard to the date/time type of these items.
      
      Arg_comparator::set_compare_func() and Arg_comparator::set_cmp_func()
      functions are changed to substitute result type of an item with the INT_RESULT
      if the item is a date/time item and another item is a constant. This is done
      to get a correct result of comparisons like date_time_function() = string_constant.
      
      
      mysql-test/r/cast.result:
        Fixed wrong test case result after bug fix#16377.
      sql/item_timefunc.h:
        Fixed bug#16377: result of DATE/TIME functions were compared as strings which
        can lead to a wrong result.
        The result_as_longlong() function is set to return TRUE for these classes:
        Item_date, Item_date_func, Item_func_curtime, Item_func_sec_to_time,
        Item_date_typecast, Item_time_typecast, Item_datetime_typecast,
        Item_func_makedate.
      sql/item_timefunc.cc:
        Fixed bug#16377: result of DATE/TIME functions were compared as strings which
        can lead to a wrong result.Correct val_int() methods are implemented for classes Item_date_typecast, 
        Item_func_makedate, Item_time_typecast, Item_datetime_typecast.
      sql/item_cmpfunc.h:
        Fixed bug#16377: result of DATE/TIME functions were compared as strings which
        can lead to a wrong result.
        Arg_comparator::set_compare_func() and Arg_comparator::set_cmp_func()
        functions are changed to substitute result type of an item with the INT_RESULT
        if the item is a date/time item and another item is a constant.
      sql/field.cc:
        Fixed bug#16377: result of DATE/TIME functions were compared as strings which
        can lead to a wrong result.
        Field::set_warning(), Field::set_datetime_warning() now use current_thd to get thd if table isn't set.
      sql/item_cmpfunc.cc:
        Fixed bug#16377: result of DATE/TIME functions were compared as strings which
        can lead to a wrong result.
        The agg_cmp_type() function now accepts THD as one of parameters. 
        In addition, it now checks if a date/time field/function is present in the
        list. If so, it tries to coerce all constants to INT to make date/time
        comparison return correct result. The field for the constant coercion is
        taken from the Item_field or constructed from the Item_func. In latter case
        the constructed field will be freed after conversion of all constant items.
        Otherwise the result is same as before - aggregated with help of the
        item_cmp_type() function.
      sql/item.h:
        The new function result_as_longlong() is added to the Item class. 
        It indicates that the item is a date/time item and result of it can be
        compared as int. Such items are date/time fields/functions.

      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.
      
      
      BitKeeper/etc/ignore:
        added mysys/test_bitmap

        Removed HA_EXTRA_RESET. MySQL will now call ::reset() instead of ::extra(HA_EXTRA_RESET).
        HA_EXTRA_RETRIVE_ALL_COLS and HA_EXTRA_RETRIVE_PRIMARY key are deleted as the column bitmaps makes these unnecessary
      include/my_bitmap.h:
        Remove my_pthread.h (should be included at upper level)
        Introduced my_bitmap_map typedef to make it the bitmap handling more like a black box

        Use copy instead of INSTALL_DB for master and slave databases.
        (Speeds up startup time a lot!)
        Remove snapshot directories at startup (removes some strange warnings)
      mysql-test/r/binlog_row_mix_innodb_myisam.result:
        Added testing of CREATE ... SELECT in a mixed environment
        (This found some bugs that Mats is going to fix shortly)
      mysql-test/r/binlog_stm_mix_innodb_myisam.result:
        Added testing of CREATE ... SELECT in a mixed environment
      mysql-test/r/create.result:
        Some extra tests of warnings and number of tables opened by CREATE ... SELECT

        Now we don't get these (wrong) warnings anymore
      mysql-test/r/view_grant.result:
        Drop used views
      mysql-test/t/create.test:
        Some extra tests of warnings and number of tables opened by CREATE ... SELECT

      mysql-test/t/multi_update.test:
        Test multi updates and deletes using primary key and without
      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
        Added HA_PRIMARY_KEY_REQUIRED_FOR_DELETE to tell MySQL to read all primary key columns in case of DELETE
      sql/ha_heap.cc:
        Update to 'newer' table handler interface
      sql/ha_heap.h:
        Update to 'newer' table handler interface
      sql/ha_innodb.cc:
        Update to 'newer' table handler interface
        - Update innobase_create_handler() to new 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:
        Update to 'newer' table handler interface

        Update to 'newer' table handler interface
      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
        HA_DUPP_POS -> HA_DUPLICATE_POS
        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()
        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

        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.

        Don't allocate TMP_TABLE_PARAM with calloc. The 'init()' function will initialize the structure properly.

        Update to new handler interface
        Simple my_snprintf -> strmake()
        Changed some constants to defines

        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()

      Fixed bug #19089. · db5d1974
      unknown authored
      When a CREATE TABLE command created a table from a materialized
      view id does not inherit default values from the underlying table.
      Moreover the temporary table used for the view materialization
      does not inherit those default values.
      In the case when the underlying table contained ENUM fields it caused
      misleading error messages. In other cases the created table contained
      wrong default values.

        mysql_prepare_table. This is not needed if we're executing
        a statement for the first time, however, at subsequent executions
        length contains the number of bytes, not characters (as it's expected

      Bug#15581: COALESCE function truncates mutli-byte TINYTEXT values · e1c61413
      unknown authored
      field.cc:
        BLOB variations have number-in-bytes limit,
        unlike CHAR/VARCHAR which have number-of-characters limits.
        A tinyblob column can store up to 255 bytes.
        In the case of basic Latin letters (which use 1 byte per character)
        we can store up to 255 characters in a tinyblob column.
        When passing an utf8 tinyblob column as an argument into
        a function (e.g. COALESCE) we need to reserve 3*255 bytes.
        I.e. multiply length in bytes to mbcharlen for the character set.
        Although in reality a tinyblob column can never be 3*255 bytes long,
        we need to set max_length to multiply to make fix_length_and_dec()
        of the function-caller (e.g. COALESCE) calculate the correct max_length
        for the column being created.

      Patch for WL#2894: Make stored routine variables work · 6b2f1309
      unknown authored
      according to the standard.
      
      The idea is to use Field-classes to implement stored routines
      variables. Also, we should provide facade to Item-hierarchy
      by Item_field class (it is necessary, since SRVs take part
      in expressions).
      
      The patch fixes the following bugs:
        - BUG#8702: Stored Procedures: No Error/Warning shown for inappropriate data 
          type matching; 
       
        - BUG#8768: Functions: For any unsigned data type, -ve values can be passed 
          and returned; 
       
        - BUG#8769: Functions: For Int datatypes, out of range values can be passed 
          and returned; 
       
        - BUG#9078: STORED PROCDURE: Decimal digits are not displayed when we use 
          DECIMAL datatype; 
       
        - BUG#9572: Stored procedures: variable type declarations ignored; 
       
        - BUG#12903: upper function does not work inside a function; 
       
        - BUG#13705: parameters to stored procedures are not verified; 
       
        - BUG#13808: ENUM type stored procedure parameter accepts non-enumerated
          data; 
       
        - BUG#13909: Varchar Stored Procedure Parameter always BINARY string (ignores 
          CHARACTER SET); 
       
        - BUG#14161: Stored procedure cannot retrieve bigint unsigned;
      
        - BUG#14188: BINARY variables have no 0x00 padding;
      
        - BUG#15148: Stored procedure variables accept non-scalar values;

      Table definition cache, part 2 · f631b361
      unknown authored
      The table opening process now works the following way:
      - Create common TABLE_SHARE object
      - Read the .frm file and unpack it into the TABLE_SHARE object
      - Create a TABLE object based on the information in the TABLE_SHARE
        object and open a handler to the table object
      
      Other noteworthy changes:
      - In TABLE_SHARE the most common strings are now LEX_STRING's
      - Better error message when table is not found
      - Variable table_cache is now renamed 'table_open_cache'
      - New variable 'table_definition_cache' that is the number of table defintions that will be cached
      - strxnmov() calls are now fixed to avoid overflows
      - strxnmov() will now always add one end \0 to result
      - engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
      - After creating a field object one must call field->init(table) before using it
      
      - For a busy system this change will give you:
       - Less memory usage for table object
       - Faster opening of tables (if it's has been in use or is in table definition cache)
       - Allow you to cache many table definitions objects
       - Faster drop of table

      sql/sql_base.cc:
        Main implementation of table definition cache
        (The #ifdef's are there for the future when table definition cache will replace open table cache)
        Now table definitions are cached indepndent of open tables, which will speed up things when a table is in use at once from several places
        Views are not yet cached; For the moment we only cache if a table is a view or not.
        
        Faster implementation of find_temorary_table()
        Replace 'wait_for_refresh()' with the more general function 'wait_for_condition()'

        Fixed calls to functions with new interfaces
        Don't use 'share_not_to_be_used'
        Instead of doing openfrm() when doing repair, we now have to call
        get_table_share() followed by open_table_from_share().
        Replace some fn_format() with faster unpack_filename().
        Safer strxnmov()
        part_info is now in TABLE
        Added Mikaels patch for partition and ALTER TABLE
        Instead of using 'TABLE_SHARE->is_view' use 'table_flags() & HA_NO_COPY_ON_ALTER

      sql/table.cc:
        Creation and destruct of TABLE_SHARE objects that are common for many TABLE objects
        
        The table opening process now works the following way:
        - Create common TABLE_SHARE object
        - Read the .frm file and unpack it into the TABLE_SHARE object
        - Create a TABLE object based on the information in the TABLE_SHARE
          object and open a handler to the table object
        
        open_table_def() is written in such a way that it should be trival to add parsing of the .frm files in new formats
      sql/table.h:
        TABLE objects for the same database table now share a common TABLE_SHARE object
        In TABLE_SHARE the most common strings are now LEX_STRING's
      sql/unireg.cc:
        Changed arguments to rea_create_table() to have same order as other functions

        Added OPEN_VIEW
      strings/strxnmov.c:
        Change strxnmov() to always add end \0
        This makes usage of strxnmov() safer as most of MySQL code assumes that strxnmov() will create a null terminated string
