unknown	cc2e929ac4	Bug #31887 : DML Select statement not returning same results when executed in version 5 Zero fill is a field attribute only. So we can't always propagate constants for zerofill fields : the values and expression results don't have that flag. Fixed by converting the const value to a string and using that in const propagation when the context allows it. Disable const propagation for fields with ZEROFILL flag in all the other cases. mysql-test/r/compare.result: Bug #31887: test case mysql-test/t/compare.test: Bug #31887: test case sql/item.cc: Bug #31887: If the context allows conversion of an int constant to a zero-filled string constant put the string constant instead of the int constant when doing const propagation sql/mysql_priv.h: Bug #31887: a macro to get all the Field_num descendant fields.	18 years ago

unknown	d068dd1aab	Fixed bug #32403 : query causes a crash due to stack and memory corruptions. The right pointer field of the SEL_ARG structure was not initialized in the constructor and sometimes that led to server crashes. There is no testcase because the bug occurs only when uninitialized memory has particular values, which can't be re-created in the test suite. sql/opt_range.cc: Fixed bug #32403. The eq_tree function requires that SEL_ARG::left and SEL_ARG::right are equal to null pointer if SEL_ARG type is MAYBE_KEY, but SEL_ARG::right was not initialized and contained garbage.	18 years ago

unknown	67bf39f241	Fix for bug #28837 : MyISAM storage engine error (134) doing delete with self-join When doing DELETE with self-join on a MyISAM or MERGE table, it could happen that a record being retrieved in join_read_next_same() has already been deleted by previous iterations. That caused the engine's index_next_same() method to fail with HA_ERR_RECORD_DELETED error and the whole DELETE query to be aborted with an error. Fixed by suppressing the HA_ERR_RECORD_DELETED error in hy_myisam::index_next_same() and ha_myisammrg::index_next_same(). Since HA_ERR_RECORD_DELETED can only be returned by MyISAM, there is no point in filtering this error in the SQL layer. mysql-test/r/merge.result: Added a test case for bug #28837. mysql-test/r/myisam.result: Added a test case for bug #28837. mysql-test/t/merge.test: Added a test case for bug #28837. mysql-test/t/myisam.test: Added a test case for bug #28837. sql/ha_myisam.cc: Skip HA_ERR_RECORD_DELETED silently when calling mi_rnext_same(). sql/ha_myisammrg.cc: Skip HA_ERR_RECORD_DELETED silently when calling mi_rnext_same().	18 years ago

unknown	f3f9855d13	Bug #32036 : EXISTS within a WHERE clause with a UNION crashes MySQL 5.122 There was a difference in how UNIONs are handled on top level and when in sub-query. Because the rules for sub-queries were syntactically allowing cases that are not currently supported by the server we had crashes (this bug) or wrong results (bug 32051). Fixed by making the syntax rules for UNIONs match the ones at top level. These rules however do not support nesting UNIONs, e.g. (SELECT a FROM t1 UNION ALL SELECT b FROM t2) UNION (SELECT c FROM t3 UNION ALL SELECT d FROM t4) Supports for statements with nested UNIONs will be added in a future version. mysql-test/r/subselect.result: Bug #32036: test case mysql-test/t/subselect.test: Bug #32036: test case sql/sql_yacc.yy: Bug #32036: Make the syntax rules for UNIONs in subqueries the same as for top level UNIONs.	18 years ago

unknown	13105534fa	Bug#31048: Many nested subqueries may cause server crash. This bug is actually two. The first one manifests itself on an EXPLAIN SELECT query with nested subqueries that employs the filesort algorithm. The whole SELECT under explain is marked as UNCACHEABLE_EXPLAIN to preserve some temporary structures for explain. As a side-effect of this values of nested subqueries weren't cached and subqueries were re-evaluated many times. Each time buffer for filesort was allocated but wasn't freed because freeing occurs at the end of topmost SELECT. Thus all available memory was eaten up step by step and OOM event occur. The second bug manifests itself on SELECT queries with conditions where a subquery result is compared with a key field and the subquery itself also has such condition. When a long chain of such nested subqueries is present the stack overrun occur. This happens because at some point the range optimizer temporary puts the PARAM structure on the stack. Its size if about 8K and the stack is exhausted very fast. Now the subselect_single_select_engine::exec function allows subquery result caching when the UNCACHEABLE_EXPLAIN flag is set. Now the SQL_SELECT::test_quick_select function calls the check_stack_overrun function for stack checking purposes to prevent server crash. mysql-test/t/subselect.test: Added a test case for the bug#31048: Many nested subqueries may cause server crash. mysql-test/r/subselect.result: Added a test case for the bug#31048: Many nested subqueries may cause server crash. sql/opt_range.cc: Bug#31048: Many nested subqueries may cause server crash.

unknown	c4d0901d00	Fix for bug #32221 : bug25714, mytest, mysql_client_test complaints and crashes. MySQL distributions contain a number of programs that are used only by the MySQL test suite internally, i.e. they are not indended to be invoked directly by a user. As a result, such programs are not documented, do not have any built-in help or proper error reporting, which may confuse users. This patch fixes the problem with the following changes: - mytest, libmysqltest and all references to them were removed from the distribution since they are not used anymore - bug25714 now displays an error message when run with incorrect arguments or with the --help option - mysql_client_test now does not call abort() in case of errors, instead it does a clean exit() with a proper error status.
