Georgi Kodinov	2d8869d248	Bug #49734 : Crash on EXPLAIN EXTENDED UNION ... ORDER BY <any non-const-function> Several problems fixed : 1. Non constant expressions in UNION ... ORDER BY were not correctly cleaned up in st_select_lex_unit::cleanup() causing crashes in EXPLAIN EXTENDED because of fields quoted by these expressions pointing to the already freed temporary table used to calculate the UNION. Fixed by correctly cleaning up expressions of any depth. 2. Subqueries in the order by part of UNION ... ORDER BY ... caused a crash in EXPLAIN EXTENDED because of a transformation attempt made during EXPLAIN EXTENDED execution. Fixed by not doing the transformation when in EXPLAIN. 3. Fulltext functions caused crash when in the ORDER BY part of an un-parenthesized UNION that gets "promoted" to be valid for the whole union, e.g. SELECT * FROM t1 UNION SELECT * FROM t2 ORDER BY MATCHES (a) AGAINST ('abc' IN BOOLEAN MODE). This is a case that demonstrates a more general problem of parts of the query being moved to another level. When doing such transformation late in the optimization run when most of the flags about the contents of the query are already aggregated it's possible to "split" the flags so that they correctly reflect the new queries after the transformation. In specific the ST_SELECT_LEX::ftfunc_list is holding all the free text function for all the parts of the second SELECT in the UNION and we don't know what part of that is in the ORDER BY that we're to move to the UNION level and what part is about the other parts of the second SELECT. Fixed by throwing and error when such statements are about to be processed by adding a check for the presence of MATCH() inside the ORDER BY clause that's going to get promoted to UNION. To workaround this new limitation one must parenthesize the UNION SELECTs and provide a real global ORDER BY for the UNION outside of the parenthesis.	16 years ago
Alexey Kopytov	c08e6c8867	Bug #42849 : innodb crash with varying time_zone on partitioned timestamp primary key Since TIMESTAMP values are adjusted by the current time zone settings in both numeric and string contexts, using any expressions involving TIMESTAMP values as a (sub)partitioning function leads to undeterministic behavior of partitioned tables. The effect may vary depending on a storage engine, it can be either incorrect data being retrieved or stored, or an assertion failure. The root cause of this is the fact that the calculated partition ID may differ from a previously calculated ID for the same data due to timezone adjustments of the partitioning expression value. Fixed by disabling any expressions involving TIMESTAMP values to be used in partitioning functions with the follwing two exceptions: 1. Creating or altering into a partitioned table that violates the above rule is not allowed, but opening existing such tables results in a warning rather than an error so that such tables could be fixed. 2. UNIX_TIMESTAMP() is the only way to get a timezone-independent value from a TIMESTAMP column, because it returns the internal representation (a time_t value) of a TIMESTAMP argument verbatim. So UNIX_TIMESTAMP(timestamp_column) is allowed and should be used to fix existing tables if one wants to use TIMESTAMP columns with partitioning. mysql-test/r/partition_bug18198.result: Corrected the error. mysql-test/r/partition_error.result: Corrected error texts. Added test cases for bug #42849. mysql-test/t/partition_bug18198.test: Corrected error code. mysql-test/t/partition_error.test: Corrected error codes.

Adjusted the error message. sql/sql_partition.cc: Modified fix_fields_part_func() to walk through partitioning expression tree with is_timezone_dependent_processor() and issue a warning/error if it depends on the timezone settings.

Evgeny Potemkin	bc43bff7ed	Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) MySQL manual describes values of the YEAR(2) field type as follows: values 00 - 69 mean 2000 - 2069 years and values 70 - 99 mean 1970 - 1999 years. MIN/MAX and comparison functions was comparing them as int values thus producing wrong result. Now the Arg_comparator class is extended with compare_year function which performs correct comparison of the YEAR type. The Item_sum_hybrid class now uses Item_cache and Arg_comparator objects to correctly calculate its value. To allow Arg_comparator to use func_name() function for Item_func and Item_sum objects the func_name declaration is moved to the Item_result_field class. A helper function is_owner_equal_func is added to the Arg_comparator class. It checks whether the Arg_comparator object owner is the <=> function or not. A helper function setup is added to the Item_sum_hybrid class. It sets up cache item and comparator. mysql-test/r/func_group.result: Added a test case for the bug#43668. mysql-test/t/func_group.test: Added a test case for the bug#43668. sql/item.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) Now Item_cache_int returns the type of cached item. sql/item.h: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) To allow Arg_comparator to use func_name() function for Item_func and Item_sum objects the func_name declaration is moved to the Item_result_field class. sql/item_cmpfunc.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) The Arg_comparator class is extended with compare_year function which performs correct comparison of the YEAR type. sql/item_cmpfunc.h: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) The year_as_datetime variable is added to the Arg_comparator class. It's set to TRUE when YEAR value should be converted to the YYYY-00-00 00:00:00 format for correct YEAR-DATETIME comparison. sql/item_geofunc.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) Item_func_spatial_rel::val_int chenged to use Arg_comparator's string buffers. sql/item_subselect.h: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) Added an implementation of the virtual func_name function. sql/item_sum.cc: Bug#43668: Wrong comparison and MIN/MAX for YEAR(2) The Item_sum_hybrid class now uses Item_cache and Arg_comparator objects to correctly calculate its value.

Davi Arnaut	1ca80ed19e	Bug#48370: Absolutely wrong calculations with GROUP BY and decimal fields when using IF Bug#45261: Crash, stored procedure + decimal Revert fix for Bug#45261 due to unforeseen bugs.	16 years ago
Davi Arnaut	fc39459504	Bug#45261: Crash, stored procedure + decimal The problem was that creating a DECIMAL column from a decimal value could lead to a failed assertion as decimal values can have a higher precision than those attached to a table. The assert could be triggered by creating a table from a decimal with a large (> 30) scale. Also, there was a problem in calculating the number of digits in the integral and fractional parts if both exceeded the maximum number of digits permitted by the new decimal type. The solution is to ensure that truncation procedure is executed when deducing a DECIMAL column from a decimal value of higher precision. If the integer part is equal to or bigger than the maximum precision for the DECIMAL type (65), the integer part is truncated to fit and the fractional becomes zero. Otherwise, the fractional part is truncated to fit into the space left after the integer part is copied. This patch borrows code and ideas from Martin Hansson's patch. mysql-test/r/type_newdecimal.result: Add test case result for Bug#45261. Also, update test case to reflect that an additive operation increases the precision of the resulting type by 1. mysql-test/t/type_newdecimal.test: Add test case for Bug#45261 sql/field.cc: Added DBUG_ASSERT to ensure object's invariant is maintained. Implement method to create a field to hold a decimal value from an item. sql/field.h: Explain member variable. Add method to create a new decimal field. sql/item.cc: The precision should only be capped when storing the value on a table. Also, this makes it impossible to calculate the integer part if Item::decimals (the scale) is larger than the precision. sql/item.h: Simplify calculation of integer part. sql/item_cmpfunc.cc: Do not limit the precision. It will be capped later. sql/item_func.cc: Use new method for allocating a new decimal field. Add a specialized method for retrieving the precision of a user variable item. sql/item_func.h: Add method to return the precision of a user variable. sql/item_sum.cc: Use new method for allocating a new decimal field. sql/my_decimal.h: The integer part could be improperly calculated for a decimal with 31 digits in the fractional part. sql/sql_select.cc: Use new method which truncates the integer or decimal parts as needed.	16 years ago
Anurag Shekhar	c77b836ab8	Bug#37740 Server crashes on execute statement with full text search and match against. Server crashes when executing prepared statement with duplicating MATCH() function calls in SELECT and ORDER BY expressions, e.g.: SELECT MATCH(a) AGAINST('test') FROM t1 ORDER BY MATCH(a) AGAINST('test') This query gets optimized by the server, so the value returned by MATCH() from the SELECT list is reused for ORDER BY purposes. To make this optimization server is comparing items from SELECT and ORDER BY lists. We were getting server crash because comparision function for MATCH() item is not intended to be called at this point of execution. In 5.0 and 5.1 this problem is workarounded by resetting MATCH() item to the state as it was during PREPARE. In 6.0 correct comparision function will be implemented and duplicating MATCH() items from the ORDER BY list will be optimized. mysql-test/r/fulltext.result: Updated with the test case for Bug#37740 mysql-test/t/fulltext.test: A test case for Bug#37740. sql/item_func.h: True initialization of 'table' happens in ::fix_fields(). As Item_func_match::eq() may be called before ::fix_fields(), it is expected that 'table' is initialized to 0 when it is reused. This is mostly affecting prepared statements, when the same item doesn't get destroyed, but rather cleaned up and reused.	17 years ago
Alexey Kopytov	096c12b2c4	Bug #45262 : Bad effects with CREATE TABLE and DECIMAL Using DECIMAL constants with more than 65 digits in CREATE TABLE ... SELECT led to bogus errors in release builds or assertion failures in debug builds. The problem was in inconsistency in how DECIMAL constants and fields are handled internally. We allow arbitrarily long DECIMAL constants, whereas DECIMAL(M,D) columns are limited to M<=65 and D<=30. my_decimal_precision_to_length() was used in both Item and Field code and truncated precision to DECIMAL_MAX_PRECISION when calculating value length without adjusting precision and decimals. As a result, a DECIMAL constant with more than 65 digits ended up having length less than precision or decimals which led to assertion failures. Fixed by modifying my_decimal_precision_to_length() so that precision is truncated to DECIMAL_MAX_PRECISION only for Field object which is indicated by the new 'truncate' parameter. Another inconsistency fixed by this patch is how DECIMAL constants and expressions are handled for CREATE ... SELECT. create_tmp_field_from_item() (which is used for constants) was changed as a part of the bugfix for bug #24907 to handle long DECIMAL constants gracefully. Item_func::tmp_table_field() (which is used for expressions) on the other hand was still using a simplistic approach when creating a Field_new_decimal from a DECIMAL expression. mysql-test/r/type_newdecimal.result: Added a test case for bug #45262. mysql-test/t/type_newdecimal.test: Added a test case for bug #45262. sql/item.cc: Use the new 'truncate' parameter in my_decimal_precision_to_length(). sql/item_cmpfunc.cc: Use the new 'truncate' parameter in my_decimal_precision_to_length(). sql/item_func.cc: 1. Use the new 'truncate' parameter in my_decimal_precision_to_length(). 2. Do not truncate decimal precision to DECIMAL_MAX_PRECISION for additive expressions involving long DECIMAL constants. 3. Fixed an incosistency in how DECIMAL constants and expressions are handled for CREATE ... SELECT. sql/item_func.h: Use the new 'truncate' parameter in my_decimal_precision_to_length(). sql/item_sum.cc: Use the new 'truncate' parameter in my_decimal_precision_to_length(). sql/my_decimal.h: Do not truncate precision to DECIMAL_MAX_PRECISION when calculating length in my_decimal_precision_to_length() if 'truncate' parameter is FALSE. sql/sql_select.cc: 1. Use the new 'truncate' parameter in my_decimal_precision_to_length(). 2. Use a more correct logic when adjusting value's length.	17 years ago
Gleb Shchepa	06142cd545	Bug #42778 : delete order by null global variable causes assertion .\filesort.cc, line 797 A query with the "ORDER BY @@some_system_variable" clause, where @@some_system_variable is NULL, causes assertion failure in the filesort procedures.

Gleb Shchepa	405bd2af11	Bug #44768 : SIGFPE crash when selecting rand from a view containing null The RAND(N) function where the N is a field of "constant" table (table of single row) failed with a SIGFPE. Evaluation of RAND(N) rely on constant status of its argument. Current server "seeded" random value for each constant argument only once, in the Item_func_rand::fix_fields method. Then the server skipped a call to seed_random() in the Item_func_rand::val_real method for such constant arguments. However, non-constant state of an argument may be changed after the call to fix_fields, if an argument is a field of "constant" table. Thus, pre-initialization of random value in the fix_fields method is too early. Initialization of random value by seed_random() has been removed from Item_func_rand::fix_fields method. The Item_func_rand::val_real method has been modified to call seed_random() on the first evaluation of this method if an argument is a function. mysql-test/r/func_math.result: Added test case for bug #44768. mysql-test/t/func_math.test: Added test case for bug #44768. sql/item_func.cc: Bug #44768: SIGFPE crash when selecting rand from a view containing null 1.

The mysql_change_user API call forces TDH::cleanup() on a server that frees user variable entries. However it didn't reset Item_func_set_user_var::entry to NULL because Item_func_set_user_var::cleanup() was not overloaded.

Gleb Shchepa	af5cf536bc	Bug #40761 : Assert on sum function on IF(..., CAST(longtext AS UNSIGNED), signed_val) (was: LEFT JOIN on inline view crashes server) Select from a LONGTEXT column wrapped with an expression like "IF(..., CAST(longtext_column AS UNSIGNED), smth_signed)" failed an assertion or crashed the server. IFNULL function was affected too. LONGTEXT column item has a maximum length of 32^2-1 bytes, at the same time this is a maximum possible length of any MySQL item. CAST(longtext_column AS UNSIGNED) returns some unsigned numeric result of length 32^2-1, so the result of IF/IFNULL function of this number and some other signed number will have text length of (32^2-1)+1=32^2 (one byte for the minus sign) - there is integer overflow, and the length is equal to zero. That caused assert/crash.

Ramil Kalimullin	c3dc1d6dfb	Fix for bug#40770: Server Crash when running with triggers including variable settings (rpl_sys) Problem: under certain conditions (e.g. user variables usage in triggers) accessing a user defined variable we may use a variables hash table that belongs to already deleted thread. It happens if thd= new THD; has the same address as just deleted thd as we use if (stored_thd == thd) to check. That may lead to unpredictable results, server crash etc. Fix: use thread_id instead of thd address to distinguish threads. Note: no simple and repeatable test case. sql/item_func.cc: Fix for bug#40770: Server Crash when running with triggers including variable settings (rpl_sys) - store and use thd->thread_id to distinguish threads instead of thread address as it may be the same as just deleted thread had, i.e. we may get (old_thd == new_thd) after delete old_thd; new_thd= new THD; - set entry_thread_id only when we get a real entry, clear it if the hash search fails. sql/item_func.h: Fix for bug#40770: Server Crash when running with triggers including variable settings (rpl_sys) - Item_func_set_user_var::entry_thread_id introduced.	17 years ago

Georgi Kodinov	e7a6e86f78	Bug #38637 : COUNT DISTINCT prevents NULL testing in HAVING clause IS NULL was not checking the correct row in a HAVING context. At the first row of a new group (where the HAVING clause is evaluated) the column and SELECT list references in the HAVING clause should refer to the last row of the previous group and not to the current one.

Georgi Kodinov	6d54b0443a	Bug #32124 : crash if prepared statements refer to variables in the where clause The code to get read the value of a system variable was extracting its value on PREPARE stage and was substituting the value (as a constant) into the parse tree. Note that this must be a reversible transformation, i.e. it must be reversed before each re-execution. Unfortunately this cannot be reliably done using the current code, because there are other non-reversible source tree transformations that can interfere with this reversible transformation. Fixed by not resolving the value at PREPARE, but at EXECUTE (as the rest of the functions operate). Added a cache of the value (so that it's constant throughout the execution of the query). Note that the cache also caches NULL values. Updated an obsolete related test suite (variables-big) and the code to test the result type of system variables (as per bug 74). mysql-test/extra/rpl_tests/rpl_insert_id.test: Bug #32124: removed ambiguous testcase mysql-test/r/innodb_data_home_dir_basic.result: Bug #32124: fixed wrong test case mysql-test/r/innodb_flush_method_basic.result: Bug #32124: fixed wrong test case mysql-test/r/ps_11bugs.result: Bug #32124: test case mysql-test/r/ssl_capath_basic.result: Bug #32124: fixed wrong test case mysql-test/r/ssl_cipher_basic.result: Bug #32124: fixed wrong test case mysql-test/r/variables.result: Bug #32124: system vars are shown as such in EXPLAIN EXTENDED, not as constants. mysql-test/suite/rpl/r/rpl_insert_id.result: Bug #32124: removed ambiguous testcase mysql-test/t/ps_11bugs.test: Bug #32124: test case sql/item.cc: Bug #32124: placed the code to convert string to longlong or double to a function (so that it can be reused) sql/item.h: Bug #32124: placed the code to convert string to longlong or double to a function (so that it can be reused) sql/item_func.cc: Bug #32124: moved the evaluation of system variables at runtime (val_xxx). sql/item_func.h: Bug #32124: moved the evaluation of system variables at runtime (val_xxx). sql/set_var.cc: Bug #32124: removed the code that calculated the system variable's value at PREPARE sql/set_var.h: Bug #32124: removed the code that calculated the system variable's value at PREPARE tests/mysql_client_test.c: Bug #32124 : removed the reading of the system variable, because its max length is depended on the system charset and client charset and can't be easily calculated.	17 years ago
Gleb Shchepa	e9cb71fc3a	Bug#26020: User-Defined Variables are not consistent with columns data types The "SELECT @lastId, @lastId := Id FROM t" query returns different result sets depending on the type of the Id column (INT or BIGINT). Note: this fix doesn't cover the case when a select query references an user variable and stored function that updates a value of that variable, in this case a result is indeterminate. The server uses incorrect assumption about a constantness of an user variable value as a select list item: The server caches a last query number where that variable was changed and compares this number with a current query number. If these numbers are different, the server guesses, that the variable is not updating in the current query, so a respective select list item is a constant. However, in some common cases the server updates cached query number too late. The server has been modified to memorize user variable assignments during the parse phase to take them into account on the next (query preparation) phase independently of the order of user variable references/assignments in a select item list. mysql-test/r/user_var.result: Added test case for bug #26020. mysql-test/t/user_var.test: Added test case for bug #26020. sql/item_func.cc: An update of entry and update_query_id variables has been moved from Item_func_set_user_var::fix_fields() to a separate method, Item_func_set_user_var::set_entry(). sql/item_func.h: 1.

unknown	875ad6d8b8	BUG#31168: @@hostname does not replicate Problem: in mixed and statement mode, a query that refers to a system variable will use the slave's value when replayed on slave. So if the value of a system variable is inserted into a table, the slave will differ from the master. Fix: mark statements that refer to a system variable as "unsafe", meaning they will be replicated by row in mixed mode and produce a warning in statement mode. There are some exceptions: some variables are actually replicated. Those should not be marked as unsafe. BUG#34732: mysqlbinlog does not print default values for auto_increment variables Problem: mysqlbinlog does not print default values for some variables, including auto_increment_increment and others. So if a client executing the output of mysqlbinlog has different default values, replication will be wrong. Fix: Always print default values for all variables that are replicated. I need to fix the two bugs at the same time, because the test cases would fail if I only fixed one of them. include/m_ctype.h: Added definition of ILLEGAL_CHARSET_INFO_NUMBER. We just need a symbol for a number that will never be used by any charset. ~0U should be safe since charset numbers are sequential, starting from 0. mysql-test/include/commit.inc: Upated test to avoid making statements unsafe. mysql-test/r/commit_1innodb.result: Updated test needs updated result file. mysql-test/r/mysqlbinlog.result: Updated result file. mysql-test/r/mysqlbinlog2.result: Updated result file. mysql-test/r/user_var-binlog.result: Updated result file. mysql-test/suite/binlog/r/binlog_base64_flag.result: Updated result file. mysql-test/suite/binlog/r/binlog_stm_ctype_ucs.result: Updated result file. mysql-test/suite/binlog/r/binlog_unsafe.result: Modified test file needs modified result file. mysql-test/suite/binlog/t/binlog_base64_flag.test: Need to filter out pseudo_thread_id from result since it is nondeterministic. mysql-test/suite/binlog/t/binlog_unsafe.test: Add tests that using variables is unsafe. The 'CREATE VIEW' tests didn't make sense, so I removed them. SHOW WARNINGS is not necessary either, because we get warnings for each statement in the result file. mysql-test/suite/rpl/r/rpl_row_mysqlbinlog.result: Updated result file. mysql-test/suite/rpl/r/rpl_skip_error.result: Updated result file. mysql-test/suite/rpl/t/rpl_skip_error.test: The test used @@server_id, which is not safe to replicate, so it would have given a warning. The way it used @@server_id was hackish (issue a query on master that removes rows only on master), so I replaced it by a more robust way to do the same thing (connect to slave and insert the rows only there). Also clarified what the test case does. mysql-test/t/mysqlbinlog2.test: Use --short-form instead of manually filtering out nondeterministic stuff from mysqlbinlog (because we added the nondeterministic @@pseudo_thread_id to the output). sql/item_func.cc: Added method of Item_func_get_system_var that indicates whether the given system variable will be written to the binlog or not. sql/item_func.h: Added method of Item_func_get_system_var that indicates whether the given system variable will be written to the binlog or not. sql/log_event.cc: - auto_increment_offset was not written to the binlog if auto_increment_increment=1 - mysqlbinlog did not output default values for some variables (BUG#34732). In st_print_event_info, we remember for each variable whether it has been printed or not. This is achieved in different ways for different variables: - For auto_increment_*, lc_time_names, charset_database_number, we set the default values in st_print_event_info to something illegal, so that it will look like they have changed the first time they are seen. - For charset, sql_mode, pseudo_thread_id, we add a flag to st_print_event_info which indicates whether the variable has been printed. - Since pseudo_thread_id is now printed more often, and its value is not guaranteed to be constant across different runs of the same test script, I replaced it by a constant if --short-form is used. - Moved st_print_event_info constructor from log_event.h to log_event.cc, since it now depends on ILLEGAL_CHARSET_NUMBER, which is defined in m_ctype.h, which is better to include from a .cc file than from a header file. sql/log_event.h: Added fields to st_print_event_info that indicate whether some of the variables have been written or not. Since the initialization of charset_database_number now depends on ILLEGAL_CHARSET_INFO_NUMBER, which is defined in a header file, which we'd better not include from this header file -- I moved the constructor from here to log_event.cc. sql/set_var.cc: System variables now have a flag binlog_status, which indicates if they are written to the binlog. If nothing is specified, all variables are marked as not written to the binlog (NOT_IN_BINLOG) when created. In this file, the variables that are written to the binlog are marked with SESSION_VARIABLE_IN_BINLOG. sql/set_var.h: Added flag binlog_status to class sys_var. Added a getter and a constructor parameter that sets it. Since I had to change sys_var_thd_enum constructor anyways, I simplified it to use default values of arguments instead of three copies of the constructor. sql/sql_yacc.yy: Mark statements that refer to a system variable as "unsafe", meaning they will be replicated by row in mixed mode. Added comment to explain strange piece of code just above. mysql-test/include/diff_tables.inc: New auxiliary test file that tests whether two tables (possibly one on master and one on slave) differ. mysql-test/suite/rpl/r/rpl_variables.result: New test case needs new result file. mysql-test/suite/rpl/r/rpl_variables_stm.result: New test file needs new result file. mysql-test/suite/rpl/t/rpl_variables.test: Test that INSERT of @@variables is replicated correctly (by switching to row-based mode). mysql-test/suite/rpl/t/rpl_variables_stm.test: Test that replication of @@variables which are replicated explicitly works as expected in statement mode (without giving warnings).	18 years ago

unknown	a3e83048a3	Fix for Bug#30217: Views: changes in metadata behaviour between 5.0 and 5.1. The problem was that in the patch for Bug#11986 it was decided to store original query in UTF8 encoding for the INFORMATION_SCHEMA. This approach however turned out to be quite difficult to implement properly. The main problem is to preserve the same IS-output after dump/restore. So, the fix is to rollback to the previous functionality, but also to fix it to support multi-character-set-queries properly. The idea is to generate INFORMATION_SCHEMA-query from the item-tree after parsing view declaration. The IS-query should: - be completely in UTF8; - not contain character set introducers.

unknown	9e6bb07d38	Bug#30889: filesort and order by with float/numeric crashes server There are two problems with ROUND(X, D) on an exact numeric (DECIMAL, NUMERIC type) field of a table: 1) The implementation of the ROUND function would change the number of decimal places regardless of the value decided upon in fix_length_and_dec. When the number of decimal places is not constant, this would cause an inconsistent state where the number of digits was less than the number of decimal places, which crashes filesort. Fixed by not allowing the ROUND operation to add any more decimal places than was decided in fix_length_and_dec. 2) fix_length_and_dec would allow the number of decimals to be greater than the maximium configured value for constant values of D.

unknown	ebaa05efa7	Bug#27216: functions with parameters of different date types may return wrong type of the result. There are several functions that accept parameters of different types. The result field type of such functions was determined based on the aggregated result type of its arguments. As the DATE and the DATETIME types are represented by the STRING type, the result field type of the affected functions was always STRING for DATE/DATETIME arguments. The affected functions are COALESCE, IF, IFNULL, CASE, LEAST/GREATEST, CASE. Now the affected functions aggregate the field types of their arguments rather than their result types and return the result of aggregation as their result field type. The cached_field_type member variable is added to the number of classes to hold the aggregated result field type. The str_to_date() function's result field type now defaults to the MYSQL_TYPE_DATETIME. The agg_field_type() function is added. It aggregates field types with help of the Field::field_type_merge() function. The create_table_from_items() function now uses the item->tmp_table_field_from_field_type() function to get the proper field when the item is a function with a STRING result type. libmysql/libmysql.c: Bug#27216: functions with parameters of different date types may return wrong type of the result.

unknown	8ab1830f9a	Bug#28494: Grouping by Item_func_set_user_var produces incorrect result. This is an additional fix. Item::val_xxx methods are supposed to use original data source and Item::val_xxx_result methods to use the item's result field. But for the Item_func_set_user_var class val_xxx_result methods were mapped to val_xxx methods. This leads, in particular, to producing bad sort keys and thus wrong order of the result set of queries with group by/order by clauses. The set of val_xxx_result methods is added to the Item_func_set_user_var class. It's the same as the val_xxx set of method but uses the result_field to return a value. mysql-test/t/user_var.test: Corrected test case for hte bug#28494. mysql-test/r/user_var.result: Corrected test case for hte bug#28494. sql/item_func.cc: Bug#28494: Grouping by Item_func_set_user_var produces incorrect result.

unknown	b4a35cd76e	Bug#28494: Grouping by Item_func_set_user_var produces incorrect result. The end_update() function uses the Item::save_org_in_field() function to save original values of items into the group buffer. But for the Item_func_set_user_var this method was mapped to the save_in_field method. The latter function wrongly decides to use the result_field. This leads to saving incorrect value in the grouping buffer and wrong result of the whole query. The can_use_result_field argument of the bool type is added to the Item_func_set_user_var::save_in_field() function. If it is set to FALSE then the item's result field won't be used. Otherwise it will be detected whether the result field will be used (old behaviour). Two wrapping functions for the function above are added to the Item_func_set_user_var class: the save_in_field(Field field, bool no_conversions) - it calls the above function with the can_use_result_field set to TRUE. the save_org_in_field(Field field) - same, but the can_use_result_field is set to FALSE. mysql-test/t/user_var.test: Added a test case for the bug#28494: Grouping by Item_func_set_user_var produces incorrect result. mysql-test/r/user_var.result: Added a test case for the bug#28494: Grouping by Item_func_set_user_var produces incorrect result. sql/item_func.cc: Bug#28494: Grouping by Item_func_set_user_var produces incorrect result.

unknown	755ae21b82	Bug#26277 User variable returns one type in SELECT @v and other for CREATE as SELECT @v - Adding variable m_cached_result_type to keep the variable type consistent during the execution of a statement. - Before each result set is returned to the client the description of each column is sent as meta data. Previously the result type for a column could change if the hash variable entry changed between statements. This caused the result set of the query to alternate column types in certain cases which is not supported by MySQL client-server protocol. Example: Previously this sequence: SET @a:=1; SELECT @a:="text", @a; would return "text", "text"; After the change the SELECT returns "text", 0 The reson for this is that previously the result set from 'SELECT @a;' would always be of the type STRING, whereas now the type of the variable is taken from the last SET statement. However, 'SELECT @a:="text"' will return type of STRING since the right side of the assignment is used. mysql-test/r/ps_2myisam.result: Changed test result because SQL type of a user variable now more accurately represents its Item type: since Item type of a variable can be either STRING, INT, DECIMAL or DOUBLE, SQL type of the result set metadata now can be either MYSQL_TYPE_VARCHAR, MYSQL_TYPE_LONGLONG, MYSQL_TYPE_NEWDECIMAL or MYSQL_TYPE_DOUBLE.

unknown	f252f9248a	WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control
