From 223f42b7158fee3b2464e76654142c7cd55a415e Mon Sep 17 00:00:00 2001 From: Jon Olav Hauglid Date: Wed, 7 Jul 2010 13:55:09 +0200 Subject: [PATCH 1/6] Bug #54117 crash in thr_multi_unlock, temporary table This crash occured after ALTER TABLE was used on a temporary transactional table locked by LOCK TABLES. Any later attempts to execute LOCK/UNLOCK TABLES, caused the server to crash. The reason for the crash was the list of locked tables would end up having a pointer to a free'd table instance. This happened because ALTER TABLE deleted the table without also removing the table reference from the locked tables list. This patch fixes the problem by making sure ALTER TABLE also removes the table from the locked tables list. Test case added to innodb_mysql.test. --- mysql-test/suite/innodb/r/innodb_mysql.result | 8 ++++++++ mysql-test/suite/innodb/t/innodb_mysql.test | 14 ++++++++++++++ sql/sql_table.cc | 5 +++++ 3 files changed, 27 insertions(+) diff --git a/mysql-test/suite/innodb/r/innodb_mysql.result b/mysql-test/suite/innodb/r/innodb_mysql.result index ba37a46b62a..8765f58b120 100644 --- a/mysql-test/suite/innodb/r/innodb_mysql.result +++ b/mysql-test/suite/innodb/r/innodb_mysql.result @@ -2499,4 +2499,12 @@ ORDER BY f1 DESC LIMIT 5; id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE t1 range f2,f4 f4 1 NULL 11 Using where DROP TABLE t1; +# +# Bug#54117 crash in thr_multi_unlock, temporary table +# +CREATE TEMPORARY TABLE t1(a INT) ENGINE = InnoDB; +LOCK TABLES t1 READ; +ALTER TABLE t1 COMMENT 'test'; +UNLOCK TABLES; +DROP TABLE t1; End of 5.1 tests diff --git a/mysql-test/suite/innodb/t/innodb_mysql.test b/mysql-test/suite/innodb/t/innodb_mysql.test index d802b04487e..80f14d32eb8 100644 --- a/mysql-test/suite/innodb/t/innodb_mysql.test +++ b/mysql-test/suite/innodb/t/innodb_mysql.test @@ -737,4 +737,18 @@ ORDER BY f1 DESC LIMIT 5; DROP TABLE t1; + +--echo # +--echo # Bug#54117 crash in thr_multi_unlock, temporary table +--echo # + +CREATE TEMPORARY TABLE t1(a INT) ENGINE = InnoDB; + +LOCK TABLES t1 READ; +ALTER TABLE t1 COMMENT 'test'; +UNLOCK TABLES; + +DROP TABLE t1; + + --echo End of 5.1 tests diff --git a/sql/sql_table.cc b/sql/sql_table.cc index 50045ec6d90..6de461574d8 100644 --- a/sql/sql_table.cc +++ b/sql/sql_table.cc @@ -7387,6 +7387,11 @@ view_err: mysql_unlock_tables(thd, thd->lock); thd->lock=0; } + /* + If LOCK TABLES list is not empty and contains this table, + unlock the table and remove the table from this list. + */ + mysql_lock_remove(thd, thd->locked_tables, table, FALSE); /* Remove link to old table and rename the new one */ close_temporary_table(thd, table, 1, 1); /* Should pass the 'new_name' as we store table name in the cache */ From 74f23d7e8fe99700c62749251c8844deec8c97ae Mon Sep 17 00:00:00 2001 From: Jimmy Yang Date: Fri, 9 Jul 2010 01:39:20 -0700 Subject: [PATCH 2/6] Fix bug #55039 Failing assertion: space_id > 0 in fil0fil.c. rb://396, approved by Sunny Bains. --- storage/innodb_plugin/dict/dict0crea.c | 18 +++++++++++++++--- storage/innodb_plugin/os/os0file.c | 12 ++++++++++-- 2 files changed, 25 insertions(+), 5 deletions(-) diff --git a/storage/innodb_plugin/dict/dict0crea.c b/storage/innodb_plugin/dict/dict0crea.c index f185371bfca..09353c45c8c 100644 --- a/storage/innodb_plugin/dict/dict0crea.c +++ b/storage/innodb_plugin/dict/dict0crea.c @@ -240,17 +240,29 @@ dict_build_table_def_step( ibool is_path; mtr_t mtr; ulint space = 0; + ibool file_per_table; ut_ad(mutex_own(&(dict_sys->mutex))); table = node->table; - dict_hdr_get_new_id(&table->id, NULL, - srv_file_per_table ? &space : NULL); + /* Cache the global variable "srv_file_per_table" to + a local variable before using it.

From 1837dcfee747b697bce2023d94a8daff6e393039 Mon Sep 17 00:00:00 2001 From: Alexey Kopytov Date: Fri, 23 Jul 2010 15:52:54 +0400 Subject: [PATCH 3/6] Bug #54476: crash when group_concat and 'with rollup' in prepared statements Using GROUP_CONCAT() together with the WITH ROLLUP modifier could crash the server. The reason was a combination of several facts: 1. The Item_func_group_concat class stores pointers to ORDER objects representing the columns in the ORDER BY clause of GROUP_CONCAT(). 2. find_order_in_list() called from Item_func_group_concat::setup() modifies the ORDER objects so that their 'item' member points to the arguments list allocated in the Item_func_group_concat constructor. 3. In some cases (e.g. in JOIN::rollup_make_fields) a copy of the original Item_func_group_concat object could be created by using the Item_func_group_concat::Item_func_group_concat(THD *thd, Item_func_group_concat *item) copy constructor. The latter essentially creates a shallow copy of the source object. Memory for the arguments array is allocated on thd->mem_root, but the pointers for arguments and ORDER are copied verbatim. What happens in the test case is that when executing the query for the first time, after a copy of the original Item_func_group_concat object has been created by JOIN::rollup_make_fields(), find_order_in_list() is called for this new object. It then resolves ORDER BY by modifying the ORDER objects so that they point to elements of the arguments array which is local to the cloned object. When thd->mem_root is freed upon completing the execution, pointers in the ORDER objects become invalid. Those ORDER objects, however, are also shared with the original Item_func_group_concat object which is preserved between executions of a prepared statement. So the first call to find_order_in_list() for the original object on the second execution tries to dereference an invalid pointer. The solution is to create copies of the ORDER objects when copying Item_func_group_concat to not leave any stale pointers in other instances with different lifecycles. mysql-test/r/func_gconcat.result: Test case for bug #54476. mysql-test/t/func_gconcat.test: Test case for bug #54476. sql/item_sum.cc: Copy the ORDER objects pointed to by the elements of the 'order' array in the copy constructor of Item_func_group_concat. sql/table.h: Removed the unused 'item_copy' member of the ORDER class. --- mysql-test/r/func_gconcat.result | 21 ++++++++++++++++++++- mysql-test/t/func_gconcat.test | 16 +++++++++++++++- sql/item_sum.cc | 19 ++++++++++++++++++- sql/table.h | 1 - 4 files changed, 53 insertions(+), 4 deletions(-) diff --git a/mysql-test/r/func_gconcat.result b/mysql-test/r/func_gconcat.result index 766f3b6bfaa..ae48eb1e0ff 100644 --- a/mysql-test/r/func_gconcat.result +++ b/mysql-test/r/func_gconcat.result @@ -995,6 +995,7 @@ SELECT 1 FROM 1 1 DROP TABLE t1; +End of 5.0 tests # # Bug #52397: another crash with explain extended and group_concat # @@ -1010,4 +1011,22 @@ id select_type table type possible_keys key key_len ref rows filtered Extra Warnings: Note 1003 select 1 AS `1` from (select group_concat(`test`.`t1`.`a` order by `test`.`t1`.`a` ASC separator ',') AS `GROUP_CONCAT(t1.a ORDER BY t1.a ASC)` from `test`.`t1` `t2` join `test`.`t1` group by `test`.`t1`.`a`) `d` DROP TABLE t1; -End of 5.0 tests +# +# Bug #54476: crash when group_concat and 'with rollup' in prepared statements +# +CREATE TABLE t1 (a INT); +INSERT INTO t1 VALUES (1), (2); +PREPARE stmt FROM "SELECT GROUP_CONCAT(t1.a ORDER BY t1.a) FROM t1 JOIN t1 t2 GROUP BY t1.a WITH ROLLUP"; +EXECUTE stmt; +GROUP_CONCAT(t1.a ORDER BY t1.a) +1,1 +2,2 +1,1,2,2 +EXECUTE stmt; +GROUP_CONCAT(t1.a ORDER BY t1.a) +1,1 +2,2 +1,1,2,2 +DEALLOCATE PREPARE stmt; +DROP TABLE t1; +End of 5.1 tests diff --git a/mysql-test/t/func_gconcat.test b/mysql-test/t/func_gconcat.test index e832ea316eb..926c1f92855 100644 --- a/mysql-test/t/func_gconcat.test +++ b/mysql-test/t/func_gconcat.test @@ -708,6 +708,7 @@ SELECT 1 FROM DROP TABLE t1; +--echo End of 5.0 tests --echo # --echo # Bug #52397: another crash with explain extended and group_concat @@ -719,5 +720,18 @@ EXPLAIN EXTENDED SELECT 1 FROM t1 t2, t1 GROUP BY t1.a) AS d; DROP TABLE t1; +--echo # +--echo # Bug #54476: crash when group_concat and 'with rollup' in prepared statements +--echo # ---echo End of 5.0 tests +CREATE TABLE t1 (a INT); +INSERT INTO t1 VALUES (1), (2); + +PREPARE stmt FROM "SELECT GROUP_CONCAT(t1.a ORDER BY t1.a) FROM t1 JOIN t1 t2 GROUP BY t1.a WITH ROLLUP"; +EXECUTE stmt; +EXECUTE stmt; + +DEALLOCATE PREPARE stmt; +DROP TABLE t1; + +--echo End of 5.1 tests diff --git a/sql/item_sum.cc b/sql/item_sum.cc index 228e36fc9f9..1048bd3d6ff 100644 --- a/sql/item_sum.cc +++ b/sql/item_sum.cc @@ -3034,7 +3034,6 @@ Item_func_group_concat::Item_func_group_concat(THD *thd, tree(item->tree), unique_filter(item->unique_filter), table(item->table), - order(item->order), context(item->context), arg_count_order(item->arg_count_order), arg_count_field(item->arg_count_field), @@ -3047,6 +3046,24 @@ Item_func_group_concat::Item_func_group_concat(THD *thd, { quick_group= item->quick_group; result.set_charset(collation.collation); + + /* + Since the ORDER structures pointed to by the elements of the 'order' array + may be modified in find_order_in_list() called from + Item_func_group_concat::setup(), create a copy of those structures so that + such modifications done in this object would not have any effect on the + object being copied. + */ + ORDER *tmp; + if (!(order= (ORDER **) thd->alloc(sizeof(ORDER *) * arg_count_order + + sizeof(ORDER) * arg_count_order))) + return; + tmp= (ORDER *)(order + arg_count_order); + for (uint i= 0; i < arg_count_order; i++, tmp++) + { + memcpy(tmp, item->order[i], sizeof(ORDER)); + order[i]= tmp; + } } diff --git a/sql/table.h b/sql/table.h index 3ef3c5e0cb2..9088b3b6965 100644 --- a/sql/table.h +++ b/sql/table.h @@ -55,7 +55,6 @@ typedef struct st_order { struct st_order *next; Item **item; /* Point at item in select fields */ Item *item_ptr; /* Storage for initial item */ - Item **item_copy; /* For SPs; the original item ptr */ int counter; /* position in SELECT list, correct only if counter_used is true*/ bool asc; /* true if ascending */ From 80aa8824971de3e5524537e30175b2390d0570db Mon Sep 17 00:00:00 2001 From: Gleb Shchepa Date: Sun, 1 Aug 2010 22:12:36 +0400 Subject: [PATCH 4/6] Bug #54461: crash with longblob and union or update with subquery Queries may crash, if 1) the GREATEST or the LEAST function has a mixed list of numeric and LONGBLOB arguments and 2) the result of such a function goes through an intermediate temporary table.
