From 37196951ad1e8aec5d3094bb38e36f52ee0ac565 Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Fri, 17 Jul 2009 18:35:12 +0000 Subject: When resizing a screen smaller in alternate screen mode, all the lines needed could be consumed by deleting from the bottom, leaving none to be removed from the top. In this case, don't call grid_view_delete_lines with ny of 0 as this is incorrect and causes a bounds check to fatal error if built with -DDEBUG. --- usr.bin/tmux/screen.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'usr.bin/tmux') diff --git a/usr.bin/tmux/screen.c b/usr.bin/tmux/screen.c index af09daf2b92..0f78ad76439 100644 --- a/usr.bin/tmux/screen.c +++ b/usr.bin/tmux/screen.c @@ -1,4 +1,4 @@ -/* $OpenBSD: screen.c,v 1.8 2009/07/13 10:43:52 nicm Exp $ */ +/* $OpenBSD: screen.c,v 1.9 2009/07/17 18:35:11 nicm Exp $ */ /* * Copyright (c) 2007 Nicholas Marriott @@ -183,7 +183,7 @@ screen_resize_y(struct screen *s, u_int sy) available = s->cy; if (gd->flags & GRID_HISTORY) gd->hsize += needed; - else if (available > 0) { + else if (needed > 0 && available > 0) { if (available > needed) available = needed; grid_view_delete_lines(gd, 0, available); -- cgit v1.2.3
