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);
>
254c258
< mkqid(&q, Qwinname, 0, 0);
---
> mkqid(&q, Qwinname, 0, QTFILE);
262a267,272
> if(t == Qwinname){
> mkqid(&q, Qwinname, 0, QTFILE);
> devdir(c, q, "winname", 0, eve, 0444, dp);
> return 1;
> }
>
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.
