| * Correct TRASH() macro usageSergei Golubchik2018-01-221-1/+1
| | | | | | | | | | | | | | | | | | | | TRASH was mapped to TRASH_FREE and was supposed to be used for memory that should not be accessed anymore, while TRASH_ALLOC() is to be used for uninitialized but to-be-used memory. But sometimes TRASH() was used in the latter sense. Remove TRASH() macro, always use explicit TRASH_ALLOC() or TRASH_FREE().

| | | | | | | | | | | | | | | | Backport of 7e29f2d64fb from 10.1. Create_field does not set BINARY_FLAG, so the check didn't work at all. Also, character sets were already compared, so this check would've been redundant (if it would've worked).

| | * Bug #22123583: MYSQL 5.5: MAIN.SP HAS VALGRIND ISSUESSreeharsha Ramanavarapu2015-11-031-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: ----- When a varchar column is used to fill the record in an internal temporary table, the length of the string stored in the column is not taken into account. Instead the default length of packed data is used to copy with memmove. This will cause valgrind issues since some bytes are uninitialized. SOLUTION: --------- The solution is to take into account the length of the string stored in the column while filling the record. This fix is a backport of BUG#13389854.

| | * Bug #21143080: UPDATE ON VARCHAR AND TEXT COLUMNS PRODUCESreeharsha Ramanavarapu2015-07-161-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | INCORRECT RESULTS Issue: ----- Updating varchar and text fields in the same update statement can produce incorrect results. When a varchar field is assigned to the text field and the varchar field is then set to a different value, the text field's result contains the varchar field's new value. SOLUTION: --------- Currently the blob type does not allocate space for the string to be stored. Instead it contains a pointer to the varchar string. So when the varchar field is changed as part of the update statement, the value contained in the blob also changes. The fix would be to actually store the value by allocating space for the blob's string. We can avoid allocating this space when the varchar field is not being written into.
| | * Bug#17632978 SLAVE CRASHES IF ROW EVENT IS CORRUPTEDVenkatesh Duggirala2013-12-171-13/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (MYSQLBINLOG -V CRASHES WITH THAT BINLOG) Problem: If slave receives a corrupted row event, slave server is crashing. Analysis: When slave is unpacking the row event, it is not validating the data before applying the event. If the data is corrupted for eg: the length of a field is wrong, it could end up reading wrong data leading to a crash. A similar problem happens when mysqlbinlog tool is used against a corrupted binlog using '-v' option. Due to -v option, the tool tries to print the values of all the fields. Corrupted field length could lead to a crash. Fix: Before unpacking the field, a verification will be made on the length. If it falls into the event range, only then it will be unpacked. Otherwise, "ER_SLAVE_CORRUPT_EVENT" error will be thrown. Incase mysqlbinlog -v case, the field value will not be printed and the processing of the file will be stopped.

| | * | | Bug#58190 BETWEEN no longer uses indexes for date or datetime fieldsAlexander Barkov2010-11-191-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regression introduced by WL#2649. Problem: queries with date/datetime columns did not use indexes: set names non_latin1_charset; select * from date_index_test where date_column between '2010-09-01' and '2010-10-01'; before WL#2649 indexes worked fine because charset of date/datetime columns was BINARY which always won. Fix: testing that collation of the operation matches collation of the field is only needed in case of "real" string data types. For DATE, DATETIME it's not needed. @ mysql-test/include/ctype_numconv.inc @ mysql-test/r/ctype_binary.result @ mysql-test/r/ctype_cp1251.result @ mysql-test/r/ctype_latin1.result @ mysql-test/r/ctype_ucs.result @ mysql-test/r/ctype_utf8.result Adding tests @ sql/field.h Adding new method Field_str::match_collation_to_optimize_range() for use in opt_range.cc to distinguish between "real string" types like CHAR, VARCHAR, TEXT (Field_string, Field_varstring, Field_blob) and "almost string" types DATE, TIME, DATETIME (Field_newdate, Field_datetime, Field_time, Field_timestamp) @ sql/opt_range.cc Using new method instead of checking result_type() against STRING result. Note: Another part of this problem (which is not regression) is submitted separately (see bug##58329).
| | * | | Bug #52131: SET and ENUM stored endian-dependent in binary logMats Kindahl2010-10-061-30/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replication SET and ENUM fields from a big-endian to a little- endian machine (or the opposite) that are represented using more than 1 byte (SET fields with more than 8 members or ENUM fields with more than 256 constants) will fail to replicate correctly when using row-based replication. The reason is that there are no pack() or unpack() functions for Field_set or Field_enum, which make them rely on Field::pack and Field::unpack. These functions pack data as strings, but since Field_set and Field_enum use integral types for representation, the fields are stored incorrectly on big-endian machines. This patch adds Field_enum::pack and Field_enum::unpack functions that store the integral value correctly in the binary log even on big-endian machines. Since Field_set inherits from Field_enum, it will use the same functions for packing and unpacking the field.

Now that we have metadata locks, we don't need to keep a crippled TABLE instance in the table cache to indicate that a table is locked. Remove all code that used this technique. Instead, rely on metadata locks and use the standard open_table() and close_thread_table() to manipulate with the table cache tables. Removes a list of functions that have become unused (see the comment for sql_base.cc for details). Under LOCK TABLES, keep a TABLE_LIST instance for each table that may be temporarily closed. For that, implement an own class for LOCK TABLES mode, Locked_tables_list. This is a pre-requisite patch for WL#4144. This is not exactly a backport: there is no new online ALTER table in Celosia, so the old alter table code was changed to work with the new table cache API.

We need this to keep ha_base_keytype() return HA_KEYTYPE_BINARY. - Adding BINARY_FLAG into some fields, because it's not being set automatically anymore with "my_charset_bin to my_charset_numeric" change. - Changing derivation for numeric/datetime datatypes to a weaker value, to make "SELECT concat('string', field)" use character set of the string literal for the result of the function. @ sql/item.cc - Implementing generic val_str_ascii(). - Using max_char_length() instead of direct read of max_length to make "tricky" charsets like UCS2 work. NOTE: in the future we'll possibly remove all direct reads of max_length - Fixing Item_num::safe_charset_converter(). Previously it alligned binary string to character string (for example by adding leading 0x00 when doing binary->UCS2 conversion). Now it just converts from my_charset_numbner to "tocs". - Using val_str_ascii() in Item::get_time() to make UCS2 arguments work. - Other misc changes @ sql/item.h - Changing MY_COLL_CMP_CONV and MY_COLL_ALLOW_CONV to bit operations instead of hard-coded bit masks. - Addding new method DTCollation.set_numeric(). - Adding new methods to Item. - Adding helper functions to make code look nicer: agg_item_charsets_for_string_result() agg_item_charsets_for_comparison() - Changing charset for Item_num-derived items from my_charset_bin to my_charset_numeric (which is an alias for latin1). @ sql/item_cmpfunc.cc - Using new helper functions - Other misc changes @ sql/item_cmpfunc.h - Fixing strcmp() to return max_length=2. Previously it returned 1, which was wrong, because it did not fit '-1'. @ sql/item_func.cc - Using new helper functions - Other minor changes @ sql/item_func.h - Removing unused functions - Adding helper functions agg_arg_charsets_for_string_result() agg_arg_charsets_for_comparison() - Adding set_numeric() into constructors of numeric items. - Using fix_length_and_charset() and fix_char_length() instead of direct write to max_length. @ sql/item_geofunc.cc - Changing class for Item_func_geometry_type and Item_func_as_wkt from Item_str_func to Item_str_ascii_func, to make them return UCS2 result properly (when character_set_connection=ucs2). @ sql/item_geofunc.h - Changing class for Item_func_geometry_type and Item_func_as_wkt from Item_str_func to Item_str_ascii_func, to make them return UCS2 result properly (when @@character_set_connection=ucs2). @ sql/item_strfunc.cc - Implementing Item_str_func::val_str(). - Renaming val_str to val_str_ascii for some items, to make them work with UCS2 properly. - Using new helper functions - All single-argument functions that expect string result now call this method: agg_arg_charsets_for_string_result(collation, args, 1); This enables character set conversion to @@character_set_connection in case of pure numeric input. @ sql/item_strfunc.h - Introducing Item_str_ascii_func - for functions which return pure ASCII data, for performance purposes, as well as for the cases when the old implementation of val_str() was heavily 8-bit oriented and implementing a UCS2-aware version is tricky. @ sql/item_sum.cc - Using new helper functions. @ sql/item_timefunc.cc - Using my_charset_numeric instead of my_charset_bin. - Using fix_char_length(), fix_length_and_charset() and fix_length_and_charset_datetime() instead of direct write to max_length. - Using tricky-charset aware function str_to_time_with_warn() @ sql/item_timefunc.h - Using new helper functions for charset and length initialization. - Changing base class for Item_func_get_format() to make it return UCS2 properly (when character_set_connection=ucs2). @ sql/item_xmlfunc.cc - Using new helper function @ sql/my_decimal.cc - Adding a new DECIMAL to CHAR converter with real multibyte support (e.g. UCS2) @ sql/mysql_priv.h - Introducing a new derivation level for numeric/datetime data types. - Adding macros for my_charset_numeric and MY_REPERTOIRE_NUMERIC. - Adding prototypes for str_set_decimal() - Adding prototypes for character-set aware str_to_xxx() functions. @ sql/protocol.cc - Changing charsetnr to "binary" client-side metadata for numeric/datetime data types. @ sql/time.cc - Adding to_ascii() helper function, to convert a string in any character set to ascii representation. In the future can be extended to understand digits written in various non-Latin word scripts. - Adding real multy-byte character set aware versions for str_to_XXXX, to make these these type of queries work correct: INSERT INTO t1 SET datetime_column=ucs2_expression; @ strings/ctype-ucs2.c - endptr was not calculated correctly. INSERTing of UCS2 values into numeric columns returned warnings about truncated wrong data.

| | | | | * | | | | | BUG#49618: Field length stored incorrectly in binary logMats Kindahl2009-12-151-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for InnoDB The class Field_bit_as_char stores the metadata for the field incorrecly because bytes_in_rec and bit_len are set to (field_length + 7 ) / 8 and 0 respectively, while Field_bit has the correct values field_length / 8 and field_length % 8. Solved the problem by re-computing the values for the metadata based on the field_length instead of using the bytes_in_rec and bit_len variables. To handle compatibility with old server, a table map flag was added to indicate that the bit computation is exact. If the flag is clear, the slave computes the number of bytes required to store the bit field and compares that instead, effectively allowing replication *without conversion* from any field length that require the same number of bytes to store.
| | | | | * | | | | | WL#5151: Conversion between different types when replicatingMats Kindahl2009-12-141-23/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Row-based replication requires the types of columns on the master and slave to be approximately the same (some safe conversions between strings are allowed), but does not allow safe conversions between fields of similar types such as TINYINT and INT. This patch implement type conversions between similar fields on the master and slave. The conversions are controlled using a new variable SLAVE_TYPE_CONVERSIONS of type SET('ALL_LOSSY','ALL_NON_LOSSY'). Non-lossy conversions are any conversions that do not run the risk of losing any information, while lossy conversions can potentially truncate the value. The column definitions are checked to decide if the conversion is acceptable. If neither conversion is enabled, it is required that the definitions of the columns are identical on master and slave. Conversion is done by creating an internal conversion table, unpacking the master data into it, and then copy the data to the real table on the slave.
