From e197284d4789d7caa613fc406516f58fbec02547 Mon Sep 17 00:00:00 2001 From: Dmitry Antipov Date: Fri, 3 Oct 2014 07:46:53 +0400 Subject: [PATCH] * font.c (font_list_entities): Do not add empty vector to font cache. (font_matching_entity): Likewise. If matching entity is found, insert 1-item vector with this entity instead of an entity itself (Bug#17125). --- src/ChangeLog | 6 ++++++ src/font.c | 35 +++++++++++++++++++---------------- 2 files changed, 25 insertions(+), 16 deletions(-) diff --git a/src/ChangeLog b/src/ChangeLog index 331da12aa13..9354aa09fa4 100644 --- a/src/ChangeLog +++ b/src/ChangeLog @@ -1,3 +1,9 @@ +2014-10-03 Dmitry Antipov + + * font.c (font_list_entities): Do not add empty vector to font cache. + (font_matching_entity): Likewise.
