From 7487e2e2214b27407e542df164a4d23520bbd8d8 Mon Sep 17 00:00:00 2001 From: Austin Clements Date: Mon, 6 Oct 2014 17:17:09 -0600 Subject: [PATCH] lib: Handle empty date value In the interest of robustness, avoid undefined behavior of sortable_unserialise if the date value is missing. This shouldn't happen now, but ghost messages will have blank date values. --- lib/message.cc | 3 +++ 1 file changed, 3 insertions(+) diff --git a/lib/message.cc b/lib/message.cc index bbfc2500..38bc9291 100644 --- a/lib/message.cc +++ b/lib/message.cc @@ -896,6 +896,9 @@ notmuch_message_get_date (notmuch_message_t *message) return 0; } + if (value.empty ()) + /* sortable_unserialise is undefined on empty string */ + return 0; return Xapian::sortable_unserialise (value); } -- 2.26.2
