From 76627d5fc33749cb329a6ced6ce8ba16a3bdd558 Mon Sep 17 00:00:00 2001 From: Sergey Glukhov Date: Tue, 14 Dec 2010 19:08:25 +0300 Subject: Bug#57818 string conversion function died Bug#57913 large negative number to string conversion functions crash String object which is used as result container of the item has uninitialized 'str_charset' field. This object might be used later to preform some internal operations and str_charset field is involved in these operations. It leads to crash. The fix is to intialize str_charset in my_decimal2string() func. mysql-test/r/func_str.result: test case mysql-test/t/func_str.test: test case sql/my_decimal.cc: intialize str_charset field for result string in my_decimal2string() func. --- mysql-test/t/func_str.test | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'mysql-test/t/func_str.test') diff --git a/mysql-test/t/func_str.test b/mysql-test/t/func_str.test index 3392a41519b..fdcfbcf519e 100644 --- a/mysql-test/t/func_str.test +++ b/mysql-test/t/func_str.test @@ -1362,4 +1362,11 @@ SELECT 1 FROM t1, t1 t2 ORDER BY QUOTE(t1.a); DROP TABLE t1; +--echo # +--echo # Bug#57913 large negative number to string conversion functions crash +--echo # Bug#57810 case/when/then : Assertion failed: length || !scale +--echo # +SELECT '1' IN ('1', SUBSTRING(-9223372036854775809, 1)); +SELECT CONVERT(('' IN (REVERSE(CAST(('') AS DECIMAL)), '')), CHAR(3)); + --echo End of 5.1 tests -- cgit v1.2.1
