Sergey Petrunia	2951f00be4	BUG#35478: sort_union() returns bad data when sort_buffer_size is hit - In QUICK_INDEX_MERGE_SELECT::read_keys_and_merge: when we got table->sort from Unique, tell init_read_record() not to use rr_from_cache() because a) rowids are already sorted and b) it might be that the the data is used by filesort(), which will need record rowids (which rr_from_cache() cannot provide). - Fully de-initialize the table->sort read in QUICK_INDEX_MERGE_SELECT::get_next(). This fixes BUG#35477. (bk trigger: file as fix for BUG#35478).	18 years ago
kaa@polly.(none)	6d1f3e8de5	Fix for bug #31207 : Test "join_nested" shows different strategy on IA64 CPUs / Intel's ICC compile The bug is a combination of two problems: 1. IA64/ICC MySQL binaries use glibc's qsort(), not the one in mysys. 2. The order relation implemented by join_tab_cmp() is not transitive, i.e. it is possible to choose such a, b and c that (a < b) && (b < c) but (c < a). This implies that result of a sort using the relation implemented by join_tab_cmp() depends on the order in which elements are compared, i.e. the result is implementation-specific. Since choose_plan() uses qsort() to pre-sort the join tables using join_tab_cmp() as a compare function, the results of the sorting may vary depending on qsort() implementation. It is neither possible nor important to implement a better ordering algorithm in join_tab_cmp(). Therefore the only way to fix it is to force our own qsort() to be used by renaming it to my_qsort(), so we don't depend on linker to decide that. This patch also "fixes" bug #20530: qsort redefinition violates the standard.	18 years ago
gkodinov/kgeorge@macbook.gmz	d17ad7b3a4	Bug #25831 : Deficiencies in INSERT ... SELECT ... field name resolving. Several problems fixed: 1. There was a "catch-all" context initialization in setup_tables() that was causing the table that we insert into to be visible in the SELECT part of an INSERT .. SELECT .. statement with no tables in its FROM clause. This was making sure all the under-initialized contexts in various parts of the code are not left uninitialized. Fixed by removing the "catch-all" statement and initializing the context in the parser. 2. Incomplete name resolution context when resolving the right-hand values in the ON DUPLICATE KEY UPDATE ... part of an INSERT ... SELECT ... caused columns from NATURAL JOIN/JOIN USING table references in the FROM clause of the select to be unavailable. Fixed by establishing a proper name resolution context. 3. When setting up the special name resolution context for problem 2 there was no check for cases where an aggregate function without a GROUP BY effectively takes the column from the SELECT part of an INSERT ... SELECT unavailable for ON DUPLICATE KEY UPDATE. Fixed by checking for that condition when setting up the name resolution context.	19 years ago

monty@mishka.mysql.fi	f348f62cc3	Added option --valgrind-mysqltest to mysql-test-run Added flag to Field::store(longlong) to specify if value is unsigned.

timour@mysql.com	a247282aa6	Implementation of WL#2486 - "Process NATURAL and USING joins according to SQL:2003". * Some of the main problems fixed by the patch: - in "select " queries the expanded correctly according to ANSI for arbitrary natural/using joins - natural/using joins are correctly transformed into JOIN ... ON for any number/nesting of the joins. - column references are correctly resolved against natural joins of any nesting and combined with arbitrary other joins. * This patch also contains a fix for name resolution of items inside the ON condition of JOIN ... ON - in this case items must be resolved only against the JOIN operands. To support such 'local' name resolution, the patch introduces a stack of name resolution contexts used at parse time. NOTICE: - This patch is not complete in the sense that - there are 2 test cases that still do not pass - one in join.test, one in select.test. Both are marked with a comment "TODO: WL#2486". - it does not include a new test specific for the task	21 years ago

monty@mysql.com	d35140a851	First stage of table definition cache Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon) Created Field::make_field() and made Field_num::make_field() to call this Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer. Renamed TABLE_SHARE->real_name to table_name Renamed TABLE->table_name to alias Renamed TABLE_LIST->real_name to table_name	21 years ago

monty@mysql.com	b903a129e2	Simpler arena swapping code Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root. This gives us the following benefits: - Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases) - Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT) - We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root	21 years ago
timour@mysql.com	09f1c7096c	WL#1972 "Evaluate HAVING before SELECT select-list" - Changed name resolution for GROUP BY so that derived columns do not shadow table columns from the FROM clause. As a result GROUP BY now is handled as a true ANSI extentsion. - Issue a warning when HAVING is resolved into ambiguous columns, and prefer the columns from the GROUP BY clause over SELECT columns.	21 years ago

monty@mishka.local	91ff64e107	Added options --auto-increment-increment and --auto-increment-offset. This allows one to setup a master <-> master replication with non conflicting auto-increment series. Cleaned up binary log code to make it easyer to add new state variables. Added simpler 'upper level' logic for artificial events (events that should not cause cleanups on slave). Simplified binary log handling. Changed how auto_increment works together with to SET INSERT_ID=# to make it more predictable: Now the inserted rows in a multi-row statement are set independent of the existing rows in the table. (Before only InnoDB did this correctly)	22 years ago
