Public bug reported:
Binary package hint: netpbm
Ubuntu 9.04 and 9.10, package netpbm 2:10.0-12 and 2:10.0-12ubuntu1.
ppmrainbow(1) fails unless the optional -t option is given specifying a
temporary directory. 9.04:
$ ppmrainbow -w 9 -h 1 red cyan | pnmnoraw
Use of uninitialized value $tmpdir in sprintf at /usr/bin/ppmrainbow line
58.
sh: cannot create /000.ppm: Permission denied
pnmnoraw: EOF / read error reading magic number
$
Line 58 is
push @outlist, my $outfile = sprintf "%s/%03u.ppm", $tmpdir, $n;
and $tmpdir hasn't been defined by that point unless the -t option has been
given. $tempdir, note the `e', has been defined earlier, using File::Temp's
tempdir, but that doesn't make use of the $tmpdir set by the command line.
ppmrainbow seems confused. The -t option probably shouldn't exist; $TMPDIR in
the environment is sufficient. And it doesn't work as currently documented, -t
has to be given.
** Affects: netpbm-free (Ubuntu)
Importance: Undecided
