[Maria-developers] Valgrind error in table elimination in MySQL 5.1.44 merge
by Kristian Nielsen 08 Mar '10

08 Mar '10

Hi Sergey, When I merged MySQL 5.1.44, there was a new testcase introduced: CREATE TABLE t1 (a VARCHAR(10), FULLTEXT KEY a (a)); INSERT INTO t1 VALUES (1),(2); CREATE TABLE t2 (b INT); INSERT INTO t2 VALUES (1),(2); EXPLAIN EXTENDED SELECT * FROM t1 UNION SELECT * FROM t1 ORDER BY (SELECT a FROM t2 WHERE b = 12); DROP TABLE t1,t2; This crashes the server in MariaDB. This is Bug#49734, but this bug is marked private. After my merge, the server no longer crashes, but there is a Valgrind error about uninitialised value: ==14946== Thread 9: ==14946== Conditional jump or move depends on uninitialised value(s) ==14946== at 0x71E89D: select_describe(JOIN*, bool, bool, bool, char const*) (sql_select.cc:16883) ==14946== by 0x71F585: JOIN::exec() (sql_select.cc:1837) ==14946== by 0x8467D1: st_select_lex_unit::exec() (sql_union.cc:513) ==14946== by 0x71C016: mysql_explain_union(THD*, st_select_lex_unit*, select_result*) (sql_select.cc:16927) ==14946== by 0x6880BC: execute_sqlcom_select(THD*, TABLE_LIST*) (sql_parse.cc:5091) ==14946== by 0x68A260: mysql_execute_command(THD*) (sql_parse.cc:2299) ==14946== by 0x692EB3: mysql_parse(THD*, char const*, unsigned, char const**) (sql_parse.cc:6034) ==14946== by 0x693CC5: dispatch_command(enum_server_command, THD*, char*, unsigned) (sql_parse.cc:1247) ==14946== by 0x6951C3: do_command(THD*) (sql_parse.cc:886) ==14946== by 0x6805A0: handle_one_connection (sql_connect.cc:1132) ==14946== by 0x50463F6: start_thread (pthread_create.c:297) ==14946== by 0x6026B4C: clone (in /usr/lib/debug/libc-2.7.so) The tree on Launchpad containing the merge and showing the error is lp:~maria-captains/maria/mariadb-5.1-knielsen Problem is seen in this code in sql/sql_select.cc, static void select_describe(): if (!(unit->item && unit->item->eliminated)) { if (mysql_explain_union(thd, unit, result)) DBUG_VOID_RETURN; } Here unit->item->eliminated is uninitialised. Checking the code in item_subselect.cc, I see that item->eliminated is not initialised in the constructor, only in fix_fields() and mark_as_eliminated_processor(). However, I do not know the code enough to know if the problem is missing initialisation in the constructor, or missing call of fix_fields() (or maybe something else). Can you help? Looks related to the table elimination patch. Since the bug report is privat, I have instead appended the patch in MySQL for the bug. - Kristian. ----------------------------------------------------------------------- revno: 2502.884.63 committer: Georgi Kodinov <joro(a)sun.com> branch nick: B49734-5.1-bugteam timestamp: Tue 2009-12-22 17:52:15 +0200 message: 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. diff: === modified file 'mysql-test/r/fulltext_order_by.result' --- mysql-test/r/fulltext_order_by.result 2005-08-12 16:27:54 +0000 +++ mysql-test/r/fulltext_order_by.result 2009-12-22 15:52:15 +0000 @@ -126,7 +126,7 @@ a.text, b.id, b.betreff order by match(b.betreff) against ('+abc' in boolean mode) desc; -ERROR 42S22: Unknown column 'b.betreff' in 'order clause' +ERROR 42000: Incorrect usage/placement of 'MATCH()' select a.text, b.id, b.betreff from t2 a inner join t3 b on a.id = b.forum inner join @@ -142,7 +142,7 @@ match(c.beitrag) against ('+abc' in boolean mode) order by match(b.betreff) against ('+abc' in boolean mode) desc; -ERROR 42S22: Unknown column 'b.betreff' in 'order clause' +ERROR 42000: Incorrect usage/placement of 'MATCH()' select a.text, b.id, b.betreff from t2 a inner join t3 b on a.id = b.forum inner join @@ -158,7 +158,7 @@ match(c.beitrag) against ('+abc' in boolean mode) order by match(betreff) against ('+abc' in boolean mode) desc; -text id betreff +ERROR 42000: Incorrect usage/placement of 'MATCH()' (select b.id, b.betreff from t3 b) union (select b.id, b.betreff from t3 b) order by match(betreff) against ('+abc' in boolean mode) desc; === modified file 'mysql-test/r/union.result' --- mysql-test/r/union.result 2009-05-15 07:11:07 +0000 +++ mysql-test/r/union.result 2009-12-22 15:52:15 +0000 @@ -1588,3 +1588,66 @@ Note 1003 select '0' AS `a` from `test`.`t1` union select '0' AS `a` from `test`.`t1` order by `a` DROP TABLE t1; End of 5.0 tests +# +# Bug #49734: Crash on EXPLAIN EXTENDED UNION ...
