(Why does "nobody" have a home directory? That's odd, and maybe a
little scary.)
For testing purposes, I created a /home/nobody. It was not there. Agree
it should not be there.
As a quick glance at perl5db.pl, it seems that the LineInfo directive
will just make a quick effort to open the file. On failure it will just
merrily go its way. The recipe as written will write the db.out file into
the current directory, which "nobody" may not (and probably should not)
have write access to. The LineInfo filehandle is set command buffer
its output, so it should be able to be used even on a CGI script that
just hangs and never completes.
Changing the LineInfo directive to a full path to a directory nobody
can write to (like /tmp/db.out) might be all that you need.
Otherwise, maybe a more complex wrapper script, like the one below,
around your CGI might work.
#!/usr/local/perl/5.8.1/bin/perl -w
chdir('/tmp');
$ENV{PERLDB_OPTS}='NonStop=1 LineInfo=db.out AutoTrace';
system('/usr/local/perl/5.8.1/bin/perl', '-dw',
'/home/langmead/public_html/arthur.cgi');
Will try this. Thanks.
