Ramil Kalimullin	55852670cc	Fix for bug#52397: another crash with explain extended and group_concat Problem: EXPLAIN EXTENDED was trying to resolve references to freed temporary table fields for GROUP_CONCAT()'s ORDER BY arguments. Fix: use stored original GROUP_CONCAT()'s arguments in such a case. mysql-test/r/func_gconcat.result: Fix for bug#52397: another crash with explain extended and group_concat - test result. mysql-test/t/func_gconcat.test: Fix for bug#52397: another crash with explain extended and group_concat - test case. sql/item_sum.cc: Fix for bug#52397: another crash with explain extended and group_concat - use "pargs", printing ORDER BY arguments in the Item_func_group_concat::print() instead of "order" to avoid possible reference resolving to (freed) temporary table fields.	16 years ago

Staale Smedseng	c7fad393fd	Bug #49829 Many "hides virtual function" warnings with SunStudio SunStudio compilers of late warn about methods that might hide methods in base classes due to the use of overloading combined with overriding. SunStudio also warns about variables defined in local socpe or method arguments that have the same name as a member attribute of the class. This patch renames methods that might hide base class methods, to make it easier both for humans and compilers to see what is actually called. It also renames variables in local scope. sql/field.cc: Local scope variable or method argument same as class attribute. sql/item_cmpfunc.cc: Local scope variable or method argument same as class attribute. sql/item_create.cc: Renaming base class create() to create_func(). sql/item_create.h: Renaming base class create() to create_func(). sql/protocol.cc: Local scope variable or method argument same as class attribute. sql/sql_profile.cc: Local scope variable or method argument same as class attribute. sql/sql_select.cc: Local scope variable or method argument same as class attribute. sql/sql_yacc.yy: Renaming base class create() to create_func(). storage/federated/ha_federated.cc: Local scope variable or method argument same as class attribute. storage/myisammrg/ha_myisammrg.cc: Local scope variable or method argument same as class attribute.	16 years ago
Tatiana A. Nurnberg	1fc1f462b6	Bug#49487: crash with explain extended and group_concat in a derived table When EXPLAIN EXTENDED tries to print column names, it checks whether the referenced table is CONST (in which case, the column's value rather than its name will be printed). If no proper table is reference (i.e. because a derived table was used that has since gone out of scope), this will fail spectacularly. This ports an equivalent of the fix for Bug 43354. mysql-test/r/func_gconcat.result: Show that EXPLAIN EXTENDED on a GROUP_CONCAT() on a derived table no longer crashes the server. mysql-test/t/func_gconcat.test: Show that EXPLAIN EXTENDED on a GROUP_CONCAT() on a derived table no longer crashes the server. sql/item_sum.cc: Do not de-ref what cannot be, that is, temp-tables that have gone away. This is of questionable utility anyway, since our deref has the sole purpose of checking whether the table is const (in which case, we'll substitute the column with its value in EXPLAIN EXTENDED - that is all).	16 years ago

Georgi Kodinov	a21cd97c35	Bug #45261 : Crash, stored procedure + decimal Bug #48370 Absolutely wrong calculations with GROUP BY and decimal fields when using IF Added the test cases in the above two bugs for regression testing. Added additional tests that demonstrate a incomplete fix. Added a new factory method for Field_new_decimal to create a field from an (decimal returning) Item. In the new method made sure that all the precision and length variables are capped in a proper way. This is required because Item's can have larger precision than the decimal fields and thus need to be capped when creating a field based on an Item type. Fixed the wrong typecast to Item_decimal.	16 years ago
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
Georgi Kodinov	5beae1f8dc	Bug #46080 : group_concat(... order by) crashes server when sort_buffer_size cannot allocate The NULL return from tree_insert() (on low memory) was not checked for in Item_func_group_concat::add().

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

Sergey Petrunia	fd485ad988	MWL#17: Table elimination - Make elimination work with aggregate functions. The problem was that aggregate functions reported all table bits in used_tables(), and that prevented table elimination. Fixed by making aggregate functions return more correct value from used_tables(). mysql-test/r/ps_11bugs.result: MWL#17: Table elimination - Update test results. The difference is because of Item_ref change: outer references to constants are now recognized as constants, too. mysql-test/r/subselect.result: - Update test results.

Before this diff Item_ref used the default implementation of const_item(){ return used_tables()==0; }. This is no longer true, as COUNT() now has used_tables()==0 but const_item()==FALSE. sql/item_sum.cc: MWL#17: Table elimination - Make Item_sum() and it descendants not to return all bits in used_tables(). This is needed because otherwise table elimination can't work in presense of aggregate functions - COUNT(*) now has used_tables()==0 and const_item()==FALSE. Had to change Item_ref::const_item() to account for this. sql/item_sum.h: MWL#17: Table elimination - Add comments	17 years ago

unknown	1a68ec2809	Fix for bug #35298 : GROUP_CONCAT with DISTINCT can crash the server The bug is a regression introduced by the patch for bug32798. The code in Item_func_group_concat::clear() relied on the 'distinct' variable to check if 'unique_filter' was initialized. That, however, is not always valid because Item_func_group_concat::setup() can do shortcuts in some cases w/o initializing 'unique_filter'. Fixed by checking the value of 'unique_filter' instead of 'distinct' before dereferencing. mysql-test/r/func_gconcat.result: Added test cases for bugs #35298 and #36024. mysql-test/t/func_gconcat.test: Added test cases for bugs #35298 and #36024. sql/item_sum.cc: Check if unique_filter != NULL before dereferencing it.

unknown	9d661efd7f	Bug#27219: Aggregate functions in ORDER BY. Mixing aggregate functions and non-grouping columns is not allowed in the ONLY_FULL_GROUP_BY mode. However in some cases the error wasn't thrown because of insufficient check. In order to check more thoroughly the new algorithm employs a list of outer fields used in a sum function and a SELECT_LEX::full_group_by_flag. Each non-outer field checked to find out whether it's aggregated or not and the current select is marked accordingly.

unknown	8270d9875f	Fix for bug #34512 : CAST( AVG( double ) AS DECIMAL ) returns wrong results Casting AVG() to DECIMAL led to incorrect results when the arguments had a non-DECIMAL type, because in this case Item_sum_avg::val_decimal() performed the division by the number of arguments twice.

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	c2e961cf2e	Bug#27333: subquery grouped for aggregate of outer query / no aggregate of subquery The optimizer counts the aggregate functions that appear as top level expressions (in all_fields) in the current subquery. Later it makes a list of these that it uses to actually execute the aggregates in end_send_group(). That count is used in several places as a flag whether there are aggregates functions. While collecting the above info it must not consider aggregates that are not aggregated in the current context. It must treat them as normal expressions instead. Not doing that leads to incorrect data about the query, e.g. running a query that actually has no aggregate functions as if it has some (and hence is expected to return only one row). Fixed by ignoring the aggregates that are not aggregated in the current context. One other smaller omission discovered and fixed in the process : the place of aggregation was not calculated for user defined functions.

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

unknown	e14fd2b651	Bug #27363 : Validity checks for nested set functions were not taking into account that the enclosed set function may be on a nest level that is lower than the nest level of the enclosing set function. Fixed by : - propagating max_sum_func_level up the enclosing set functions chain. - updating the max_sum_func_level of the enclosing set function when the enclosed set function is aggregated above or on the same nest level of as the level of the enclosing set function. - updating the max_arg_level of the enclosing set function on a reference that refers to an item above or on the same nest level as the level of the enclosing set function. - Treating both Item_field and Item_ref as possibly referencing items from outer nest levels. mysql-test/r/subselect.result: Bug #27363: test cases mysql-test/t/subselect.test: Bug #27363: test cases sql/item.cc: Bug #27363: Treat the reference as an outer reference for the enclosing set function even if it's referencing an item that is above the nest level of the enclosing set function. Consider both Item_field and Item_ref. sql/item_sum.cc: Bug #27363: Use the enclosed set function aggregation level to mark the enclosing set function even if it's aggregated on a level that is above the nest level of the enclosing set function. Pass max_sum_func_level up the accending branch of the recursion because it must take into account each directly or indirectly nested set function.	19 years ago
unknown	40c1a3f9a2	Bug #26815 : When creating a temporary table the concise column type of a string expression is decided based on its length: - if its length is under 512 it is stored as either varchar or char. - otherwise it is stored as a BLOB. There is a flag (convert_blob_length) to create_tmp_field that, when >0 allows to force creation of a varchar if the max blob length is under convert_blob_length. However it must be verified that convert_blob_length (settable through a SQL option in some cases) is under the maximum that can be stored in a varchar column. While performing that check for expressions in create_tmp_field_from_item the max length of the blob was used instead. This causes blob columns to be created in the heap temp table used by GROUP_CONCAT (where blobs must not be created in the temp table because of the constant convert_blob_length that is passed to create_tmp_field() ). And since these blob columns are not expected in that place we get wrong results. Fixed by checking that the value of the flag variable is in the limits that fit into VARCHAR instead of the max length of the blob column. mysql-test/r/func_gconcat.result: Bug #26815: test case mysql-test/t/func_gconcat.test: Bug #26815: test case sql/item_sum.cc: Bug #26815: wrong length was checked sql/sql_select.cc: Bug #26815: wrong length was checked	19 years ago
unknown	ec3de56263	Fixed bug #27348 . If a set function with a outer reference s(outer_ref) cannot be aggregated the outer query against which the reference has been resolved then MySQL interpretes s(outer_ref) in the same way as it would interpret s(const). Hovever the standard requires throwing an error in this situation. Added some code to support this requirement in ansi mode. Corrected another minor bug in Item_sum::check_sum_func. mysql-test/r/subselect.result: Added a test case for bug #27348. mysql-test/t/subselect.test: Added a test case for bug #27348. sql/item_sum.cc: Fixed bug #27348.

unknown	d95c307f1d	This is a fix for the memory corruption occurred in one of test cases from func_group.test after the patch for bug #27229 had been applied. The memory corruption happened because in some rare cases the function count_field_types underestimated the number of elements in in the array param->items_to_copy. sql/item_sum.cc: The return value of the Item_sum::update_used_tables method should not depend on the place of aggregation of the set function for which the Item_sum object has been created. sql/sql_select.cc: This is a fix for the memory corruption occurred in one of test cases from func_group.test after the patch for bug #27229 had been applied. The memory corruption happened because in some rare cases the function count_field_types underestimated the number of elements in in the array param->items_to_copy. Currently it's not guaranteed that after JOIN::prepare() the used_tables attribute is calculated for all items. For example for the expression SUM(outer_ref)+1 used_tables() must return OUTER_REF_TABLE_BIT. Yet by the moment when the used_tables attribute is calculated in JOIN::prepare SUM(outer_ref) has not been substituted for Item_aggregate_ref yet. By this reason additional calls of the method update_used_tables are needed for some items passed as parameters to the function create_tmp_table.	19 years ago
