mogilefs newbie help

[Robert Rogers]

 FYI,

It seems like this code is never called: 

        if ($! == ENOENT) {
            # directory doesn't exist, so let's manually create it
            eval { File::Path::mkpath($path, 0, 0755); };
            return $self->system_error("Unable to create directory", "path = $path, file = $file") if $@;
            print STDERR "debug ENOENT: path=$path file=$file, fd=$fd; err=$!\n";
            # should be created, call self recursively to try
            return $self->attempt_open($path, $file);
        } elsif ($!) {
            return $self->system_error("Internal error", "error = $!, path = $path, file = $file");
        }


ie the directories are never made. weird.

so, i did this hack (i should use all caps) and it now works:
$! = ENOENT if $fd == -1;

here:
 my $fd = shift;
        $! = ENOENT if $fd == -1;
        print STDERR "debug: fd=$fd; err=$! : also ENOENT maybe: " . ENOENT . "\n";
        # verify file was opened


Thoughts?
