Vladislav Vaintroub	64e308e28d	Fix build and packaging on Windows: - build executables we have in 5.3 (mysql_install_db.exe, mysq_upgrade_service.exe, upgrade wizard), and MSI - add some missing headers to windows specific source files. This needs to be done since 5.5 is using WIN32_LEAN_AND_MEAN preprocessor constant thus windows.h no more includes whiole Windows - do not deliver perl scripts (mysql_install_db.pl & friends) -they do not work, are not documented, and we have native executables for this functionality. do not pack echo.exe, replace.exe into MSI, they are not needed. Do not build resolveip on Windows, it is not used. - precache results of of system checks in cmake/os/WindowsCache.cmake (like it is alreay done for majority of tests to speed up cmake run with VS) - make feedback plugin DEFAULT on Windows (so MSI works if user enables plugin), fix null pointer access in PSI_register	14 years ago
Vladislav Vaintroub	6be24a771a	Avoid mysqld dependency on libaio.so by linking xtradb statically to libaio. A variable XTRADB_PREFER_STATIC_LIBAIO should be set to 1 (or TRUE or ON) for static linking. Even if mysqld can avoid dependency on shared libaio, shared libraries libmysqld.so or ha_innodb.so cannot link without it. Given that the patch primarily addresses building tar.gz package, and shared libraries mentioned above deemed less important than mysqld executable, we accept shared lib dependency on libaio.so	14 years ago

Igor Babaev	b2e5a3f603	Fixed LP bug #887496 . This bug in the function Loose_scan_opt::check_ref_access_part1 could lead to choosing an invalid execution plan employing a loose scan access to a semi-join table even in the cases when such access could not be used at all. This could result in wrong answers for some queries with IN subqueries.	14 years ago
unknown	f8dbbc010f	Fix bug lp:833777 Analysis: The optimizer distinguishes two kinds of 'constant' conditions: expensive ones, and non-expensive ones. The non-expensive conditions are evaluated inside make_join_select(), and if false, already the optimizer detects empty query results. In order to avoid arbitrarily expensive optimization, the evaluation of expensive constant conditions is delayed until execution. These conditions are attached to JOIN::exec_const_cond and evaluated in the beginning of JOIN::exec. The relevant execution logic is: JOIN::exec() { if (! join->exec_const_cond->val_int()) { produce an empty result; stop execution } continue execution execute the original WHERE clause (that contains exec_const_cond) ... } As a result, when an expensive constant condition is TRUE, it is evaluated twice - once through JOIN::exec_const_cond, and once through JOIN::cond. When the expensive constant condition is a subquery, predicate, the subquery is evaluated twice. If we have many levels of subqueries, this logic results in a chain of recursive subquery executions that walk a perfect binary tree. The result is that for subquries with depth N, JOIN::exec is executed O(2^N) times. Solution: Notice that the second execution of the constant conditions happens inside do_select(), in the branch: if (join->table_count == join->const_tables) { ... } In this case exec_const_cond is equivalent to the whole WHERE clause, therefore the WHERE clause has already been checked in the beginnig of JOIN::exec, and has been found to be true. The bug is addressed by not evaluating the WHERE clause if there was exec_const_conds, and it was TRUE.	14 years ago

Igor Babaev	3c496ea9ad	Fixed LP bug #892725 . A non-first execution of a prepared statement missed a call of the TABLE_LIST::process_index_hints() method in the code of the function setup_tables(). At some scenarios this could lead to the choice of a quite inefficient execution plan for the base query of the prepared statement.	14 years ago

Igor Babaev	6ed9c13643	Fixed LP bug #891953 . Due to this bug the function SEL_IMERGE::or_sel_tree_with_checks() could build an inconsistent merge tree if one of the SEL_TREEs in the resulting index merge happened to contain a full key range. This could trigger an assertion failure.	14 years ago

unknown	42221abaed	Fix bug lp:869036 Apart from the fix, the patch also adds few more unrelated test cases for partial matching, and fixes few typos. Analysis: This bug uncovered that partial matching via rowid intersection didn't handle the case when: - the left IN argument has some NULLs, - there are no non-null value matches, and there is no non-null column, - the subquery columns that are not covered with the NULLs in the left IN argument contain at least one row, such that it has NULL values in all columns where the left IN operand has no NULLs. In this case there is a partial match. In addition the analysis of the related code uncovered incorrect handling of few other related cases. Solution: The solution for the bug is to check if there exists a row with NULLs in all columns other than the ones having NULL in the let IN operand. The check is implemented via checking whether the bitmaps that store NULL information in class Ordered_key have a non-empty intersection for the relevant columns. The intersection itself is implemented via the function bitmap_exists_intersection() in my_bitmap.c.	14 years ago
Igor Babaev	c05e5b9c65	Fixed LP bug #887479 . The function setup_semijoin_dups_elimination erroneously assumed that if join_cache_level is set to 3 or 4 then the type of the access to a table cannot be JT_REF or JT_EQ_REF. This could lead to wrong query result sets.	14 years ago
