8b48986f4c drw.c: drw_scm_free: call free inside
Because drw_scm_create() allocates it.

b1e217b29a XUngrabKeyboard() instead of XUngrabKey()
XUngrabKey(), which is currently used in cleanup(), is not the right
counterpart to XGrabKeyboard(), which is used in grabkeyboard(),
called from main().

XUngrabKeyboard() is the function to use, as grabbing the whole
keyboard is different to grabbing individual keys.

With the current code the keyboard gets ungrabbed, as far as I can tell,
only by the final XCloseDisplay() in cleanup(), as the XUngrabKey()
there effectively does nothing.

475d8093cb drw.c: use the same pattern as ellipsis_width to check for infinite recursion 2024-07-14 11:43:01 +02:00

59936c7d97 render invalid utf8 sequences as U+FFFD
previously drw_text would do the width calculations as if
invalid utf8 sequences were replaced with U+FFFD but would pass
the invalid utf8 sequence to xft to render where xft would just
cut it off at the first invalid byte.

this change makes invalid utf8 render as U+FFFD and avoids
sending invalid sequences to xft. the following can be used to
check the behavior before and after the patch:

	$ printf "0\xef1234567\ntest" | dmenu
