From 6330815a0ce15311cb90781d633b4c8cdfd34834 Mon Sep 17 00:00:00 2001 From: Sergey Glukhov Date: Mon, 13 Dec 2010 13:39:26 +0300 Subject: Bug#58396 group_concat and explain extended are still crashy Explain fails at fix_fields stage and some items are left unfixed, particulary Item_group_concat. Item_group_concat::orig_args field is uninitialized in this case and Item_group_concat::print call leads to crash. The fix: move the initialization of Item_group_concat::orig_args into constructor. mysql-test/r/func_gconcat.result: test case mysql-test/t/func_gconcat.test: test case sql/item_sum.cc: move the initialization of Item_group_concat::orig_args into constructor. --- mysql-test/t/func_gconcat.test | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'mysql-test/t/func_gconcat.test') diff --git a/mysql-test/t/func_gconcat.test b/mysql-test/t/func_gconcat.test index a7072362759..1475ca082a5 100644 --- a/mysql-test/t/func_gconcat.test +++ b/mysql-test/t/func_gconcat.test @@ -746,4 +746,15 @@ SELECT POLYGON((SELECT 1 FROM (SELECT 1 IN (GROUP_CONCAT(t1.f1)) FROM t1, t1 t G --enable_ps_protocol DROP TABLE t1; +--echo # +--echo # Bug#58396 group_concat and explain extended are still crashy +--echo # + +CREATE TABLE t1(a INT); +--error ER_UNKNOWN_ERROR +EXPLAIN EXTENDED SELECT UPDATEXML('1', a, '1') +FROM t1 ORDER BY (SELECT GROUP_CONCAT(1) FROM t1); +SHOW WARNINGS; +DROP TABLE t1; + --echo End of 5.1 tests -- cgit v1.2.1
