From 46dee0d1848e24e39fc236e78a438efa22356f8d Mon Sep 17 00:00:00 2001 From: Alexander Barkov <bar@mariadb.org> Date: Mon, 5 Dec 2016 16:50:12 +0400 Subject: MDEV-10717 Assertion `!null_value' failed in virtual bool Item::send(Protocol*, String*) The problem was that null_value was not set to "false" on a well-formed row. If an ill-formed row was followed by a well-forned row, null_value remained "true" in the call of Item::send() for the well-formed row. --- sql/item.cc | 1 + 1 file changed, 1 insertion(+) (limited to 'sql') diff --git a/sql/item.cc b/sql/item.cc index 3448b236640..ede1df6aa9b 100644 --- a/sql/item.cc +++ b/sql/item.cc @@ -5743,6 +5743,7 @@ String *Item::check_well_formed_result(String *str, bool send_error) uint wlen= cs->cset->well_formed_len(cs, str->ptr(), str->ptr() + str->length(), str->length(), &well_formed_error); + null_value= false; if (wlen < str->length()) { THD *thd= current_thd; -- cgit v1.2.1
