I've been tracking down why the latest devdraw.c that includes winname =
just wasn't being read by rio in my drawterm-cocoa port.  What I found =
is that /dev/winname is created during the #i initialization but =
subsequently never found in drawgen() after the qid has been created =
from Qtopdir.  The following diff against the most recent Plan 9 sources =
versions of devdraw.c shows the change that lets drawterm resize the =
window and have rio pick up the change:

% diff /usr/local/src/plan9.bell-labs.com/plan9/sys/src/9/port/devdraw.c =
kern/devdraw.c
> drawgen(Chan *c, char *name, Dirtab *dt, int ndt, int s, Dir *dp)
218a219,222
> 	USED(name);
> 	USED(dt);
> 	USED(ndt);
>=20
254c258
< 			mkqid(&q, Qwinname, 0, 0);
---
> 			mkqid(&q, Qwinname, 0, QTFILE);
262a267,272
> 	if(t =3D=3D Qwinname){
> 			mkqid(&q, Qwinname, 0, QTFILE);
> 			devdir(c, q, "winname", 0, eve, 0444, dp);
> 			return 1;
> 	}
>=20

These missing lines don't appear to be an issue in devvga.c or in the =
current 9vx.


Now that I've got clean resizing of a drawterm window working I'll be =
focused on cleaning up the rest of the diffs and pushing out a new =
version for OS X in the near term.
