HI


I've been able to burn a data CD, and was trying my hands at burning an
audio CD. Burning itself went fine, but the step prior to that was a
a bit botched. After running cdfs, there are several files served in
/mnt/cd (axxx, ctl), but when copying them, cdfs does not end input
on file boundaries.

i.e.,
		cp /mnt/cd/a000 /tmp/the_clash/
will copy all of track a000, a001 ... into one file in /tmp/the_clash.
I fixed this to a certain degree with the following fix to
/sys/src/cmd/cdfs/mmc.c:

namaste% diff mmc.c mmc.c.orig
541,550d540
< 	/*	Trunc nblock modulo size of track	*/
< 	if((off+nblock) > o->track->end) {
< 		if ((nblock = o->track->end - off) == 0) {
< 			werrstr("end of track (%ld->%ld)", o->track->beg, o->track->end);
< 			if(vflag)
< 				fprint(2, "end of track (%ld->%ld)", o->track->beg, o->track->end);
< 			return -1;
< 		}
< 	}
<
589c579
< 	//fprint(2, "nblock = %ld\n", nblock);
---
> 	fprint(2, "nblock = %ld\n", nblock);
namaste%



The fix works real horrorshow. I just made an 'archival copy' of
a cd with it.
