From db2236001c1cb042a2f24052849da96578273b1c Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Wed, 27 Dec 2017 13:36:53 +0100 Subject: dont NUL terminate _NET_WM_NAME Reported by Kernc, thanks! "This makes a particular program that uses libwnck [1] fail after: Wnck-WARNING **: Property _NET_WM_NAME contained invalid UTF-8 in this code [2] because the returned string contains a '\0' and the documentation for g_utf8_validate() [3] explicitly states that when string length is provided, no nul bytes are allowed." It is not entirely clear it is incorrect, other WM's seem to not NUL terminate it either though. --- dwm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/dwm.c b/dwm.c index ff893df5..ec6a27c6 100644 --- a/dwm.c +++ b/dwm.c @@ -1579,7 +1579,7 @@ setup(void) XChangeProperty(dpy, wmcheckwin, netatom[NetWMCheck], XA_WINDOW, 32, PropModeReplace, (unsigned char *) &wmcheckwin, 1); XChangeProperty(dpy, wmcheckwin, netatom[NetWMName], utf8string, 8, - PropModeReplace, (unsigned char *) "dwm", 4); + PropModeReplace, (unsigned char *) "dwm", 3); XChangeProperty(dpy, root, netatom[NetWMCheck], XA_WINDOW, 32, PropModeReplace, (unsigned char *) &wmcheckwin, 1); /* EWMH support per view */ -- cgit v1.2.3
