Solution: - Removing class Item_ident_for_show - Implementing a new method Protocol::send_list_fields() instead, which accepts a List<Field> instead of List<Item> as input. Now no any Item creation is done during mysqld_list_fields(). Adding helper methods, to reuse the code easier: - Moved a part of Protocol::send_result_set_metadata(), responsible for sending an individual field metadata, into a new method Protocol_text::store_field_metadata(). Reusing it in both send_list_fields() and send_result_set_metadata(). - Adding Protocol_text::store_field_metadata() - Adding Protocol_text::store_field_metadata_for_list_fields() Note, this patch also automatically fixed another bug: MDEV-18685 mysql_list_fields() returns DEFAULT 0 instead of DEFAULT NULL for view columns The reason for this bug was that Item_ident_for_show::val_xxx() and get_date() did not check field->is_null() before calling field->val_xxx()/get_date(). Now the default value is correctly sent by Protocol_text::store(Field*).

These names looked similar to other functions that are used for a very different purpose (creating Field instances): - Public function "Field * make_field(..)" - Method "Field *Column_defitinion::make_field(..)" The rename makes it's easier to search the code using "grep".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Item_param::set_value() did not set Item::collation and Item_param::str_value_ptr.str_charset properly. So both metadata and data for OUT parameters were sent in a wrong way to the client. This patch removes the old implementation of Item_param::set_value() and rewrites it using Type_handler::Item_param_set_from_value(), so now setting IN and OUT parameters share the a lot of code. 1. Item_param::set_str() now: - accepts two additional parameters fromcs, tocs - sets str_value_ptr, to make sure it's always in sync with str_value, even without Item_param::convert_str_value() - does collation.set(tocs, DERIVATION_COERCIBLE), to make sure that DTCollation is valid even without Item_param::convert_str_value() 2. Item_param::set_value(), which is used to set OUT parameters, now reuses Type_handler::Item_param_set_from_value(). 3. Cleanup: moving Item_param::str_value_ptr to private, as it's not needed outside. 4. Cleanup: adding a new virtual method Settable_routine_parameter::get_item_param() and using it a few new DBUG_ASSERTs, where Item_param cannot appear. After this change: 1. Assigning of IN parameters works as before: a. Item_param::set_str() is called and sets the value as a binary string b. The original value is sent to the query used for binary/general logging c. Item_param::convert_str_value() converts the value from the client character set to the connection character set 2. Assigning of OUT parameters works in the new way: a. Item_param::set_str() and sets the value using the source Item's collation, so both Item::collation and Item_param::str_value_ptr.str_charset are properly set. b. Protocol_binary::send_out_parameters() sends the value to the client correctly: - Protocol::send_result_set_metadata() uses Item::collation.collation (which is now properly set), to detect if conversion is needed, and sends a correct collation ID. - Protocol::send_result_set_row() calls Type_handler::Item_send_str(), which uses Item_param::str_value_ptr.str_charset (which is now properly set) to actually perform the conversion.

Now fixed - Several bugs found and fixed (Access to null pointers, access of freed memory, wrong arguments to printf like functions) - Removed a lot of casts from (const char*) to (char*) Changes: - This caused some ABI changes - lex_string_set now uses LEX_CSTRING - Some fucntions are now taking const char* instead of char* - Create_field::change and after changed to LEX_CSTRING - handler::connect_string, comment and engine_name() changed to LEX_CSTRING - Checked printf() related calls to find bugs.

As a result, the execution always used Item_ident_for_show::val_real() to send the default value of the field, so most default values for non-numeric types were displayed as '0'. This patch: 1. Cleanup: a. Removes Send_field::charsetnr, as it's been unused since introduction of Item::charset_for_protocol() in MySQL-5.5. b. Adds the "const" qualifier to Field::char_length(). This is needed for (5.a), see below. 2. Introduces a new virtual method Type_handler::charset_for_protocol(), returning item->collation.collation for string data types, or &my_charset_bin for non-string data types. 3. Changes Item::charset_for_protocol() from virtual to non-virtual. It now calls type_handler()->charset_for_protocol(). As a good side effect, duplicate code in Item::charset_for_protocol() and Item_temporal_hybrid_func::charset_for_protocol() is now gone. 4. Fixes Item_ident_for_show::field_type() to correctly return its data type according to the data type of the referenced field. This actually fixes the problem reported in MDEV-11672. Now the default value is sent using a correct method, e.g. val_str() for VARCHAR/TEXT, or val_int() for INT/BIGINT. This required additional changes: a. in DBUG_ASSERT in Protocol::store(const char *,size_t,CHARSET_INFO), This method is now used by mysqld_list_fields(), which (unlike normal SELECT queries) does not set field_types/field_pos/field_count. b. Item_ident_for_show::Item_ident_for_show() now set standard attributes (collation, decimals, max_length, unsigned_flag) according to the referenced field, to make charset_for_protocol() return the correct value and to make mysqld_list_fields() correctly send default values. 5. In order to share the code between Item_field::set_field() and Item_ident_for_show::Item_ident_for_show(): a. Introduces a new method Type_std_attributes::set(const Field*) b. To make (a) possible, moves Item::fix_char_length() from Item to Type_std_attributes, also moves char_to_byte_length_safe() from item.h to sql_type.h c. Additionally, moves Item::fix_length_and_charset() and Item::max_char_length() from Item to Type_std_attributes. This is not directly needed for the fix and is done just for symmetry with fix_char_length(), as these three methods are directly related to each other.

Fixed the following way: - The client accepts now error packages with a packet number one less than expected. - To ensure that this issue can be detected early in my_real_read(), error messages sent to the client are not compressed, even when compressed protocol is used.

It's only used in asserts and my_decimal_int_part. - FLOATING_POINT_DECIMALS (31) is used to mark that a FLOAT or DOUBLE was defined without decimals. This is regarded as a floating point value. - Max decimals allowed for FLOAT and DOUBLE is FLOATING_POINT_DECIMALS-1 - Clients assumes that float and double with decimals >= NOT_FIXED_DEC are floating point values (no decimals) - In the .frm decimals=FLOATING_POINT_DECIMALS are used to define floating point for float and double (31, like before) To ensure compatibility with old clients we do: - When storing float and double, we change NOT_FIXED_DEC to FLOATING_POINT_DECIMALS. - When creating fields from .frm we change for float and double FLOATING_POINT_DEC to NOT_FIXED_DEC - When sending definition for a float/decimal field without decimals to the client as part of a result set we convert NOT_FIXED_DEC to FLOATING_POINT_DECIMALS. - variance() and std() has changed to limit the decimals to FLOATING_POINT_DECIMALS -1 to not get the double converted floating point. (This was to preserve compatiblity) - FLOAT and DOUBLE still have 30 as max number of decimals. Bugs fixed: variance() printed more decimals than we support for double values. New behaviour: - Strings now have 38 decimals instead of 30 when converted to decimal - CREATE ... SELECT with a decimal with > 30 decimals will create a column with a smaller range than before as we are trying to preserve the number of decimals. Other changes - We are now using the obsolete bit FIELDFLAG_LEFT_FULLSCREEN to specify decimals > 31 - NOT_FIXED_DEC is now declared in one place - For clients, NOT_FIXED_DEC is always 31 (to ensure compatibility). On the server NOT_FIXED_DEC is DECIMAL_NOT_SPECIFIED (39) - AUTO_SEC_PART_DIGITS is taken from DECIMAL_NOT_SPECIFIED - DOUBLE conversion functions are now using DECIMAL_NOT_SPECIFIED instead of NOT_FIXED_DEC
