It would be cool if you could tell gbr to randomize the order of the music it's queueing.

If you have a huge library of music, but you only want e.g. 20 songs to be queued, you should have the option to tell gbr to only queue the first 20 songs. This could be used in conjunction with the randomize function as well, to queue e.g. 20 random songs from your entire library.

I mentioned briefly on zephyr, but when zsr came back up, jobs submitted from non-cups (or is it non-IPP?) clients were getting stuck in a held state: root@zygorthian-space-raiders:~# lpstat -l -osipbmp3 sipbmp3-13382 kaduk 3861504 Fri 03 Dec 2010 9:18:00 PM EST

Alerts: job-hold-until-specified queued for sipbmp3

(jobs submitted using cups clients played uneventfully)

Looking at /tmp/gutenbach.log , we see a bunch of things like: STDERR FROM SPOOL FILTER Got @ARGV: $VAR1 = [

There is more in /var/log/cups/error_log (.1.gz at the moment), but it is less interesting: D [03/Dec/2010:21:03:56 -0500] [Job 13381] The following messages were recorded from 09:03:56 PM to 09:03:56 PM D [03/Dec/2010:21:03:56 -0500] [Job 13381] Job submission timed out.

So the gziptoany filter's error is what is shown in the super-verbose lpstat output, which is a bit confusing to users.

Going back to the error in gutenbach.log, it's coming from here:

69 # If we weren't given a filename, we need to read from stdin. Since 70 # mplayer really wants a file, let's write out to a temporary file 71 # first. 72 if (!$arguments{"file"}) { 73 my ($fh, $file) = tempfile("gutenbachXXXXX", UNLINK => 1); # Ask File::Temp for a safe temporary file 74 my $buf; 75 while (read(STDIN, $buf, 1024*1024)) { # Read 1M at a time and put it in the temporary file 76 print $fh $buf; 77 } 78 close($fh); 79 $arguments{"file"} = $file; 80 }

The call to tempfile() on line 73 fails, I presume because it is running as an unprivileged user (lp?) in a PWD (/root ?) that it is not authorized to write to. The workaround that I put in place was to just hardcode the tempfile path to begin in /tmp -- but I'm not very happy with that, not knowing for sure where it was trying to write and as what user.
