From e4827b0c4048718ab06670cf60ef68d028fe7fc4 Mon Sep 17 00:00:00 2001 From: NRK Date: Mon, 28 Mar 2022 01:02:52 +0600 Subject: [PATCH] drw_text: don't segfault when called with 0 width this patch just rejects *any* 0 width draws, which is surely an error by the caller. this also guards against cases where the width is too small for the ellipsis to fit, so ellipsis_w will remain 0. reported by Bakkeby --- drw.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drw.c b/drw.c index a50c9ee..2f3a5df 100644 --- a/drw.c +++ b/drw.c @@ -267,7 +267,7 @@ drw_text(Drw *drw, int x, int y, unsigned int w, unsigned int h, unsigned int lp enum { nomatches_len = 64 }; static struct { long codepoint[nomatches_len]; unsigned int idx; } nomatches; - if (!drw || (render && !drw->scheme) || !text || !drw->fonts) + if (!drw || (render && (!drw->scheme || !w)) || !text || !drw->fonts) return 0; if (!render) {
