Apache::AuthCookie: undefined value in subroutine call -- solved

[Vivek Khera <kh...@kcilink.com>]

I've had this long standing warning in my application:

Use of uninitialized value in subroutine entry at
 /var/vkmlm/perllib/MLM/MLMhandler.pm line 80

And this is what the line was:

    my $subr = $r->lookup_uri($uri);

Naturally, $uri is *always* defined, and the warning only shows up
some of the time.

I finally tracked down the right conditions to repeat the warning at
will, which let me find the actual cause.  It turns out to be the
method Apache::AuthCookie->recognize_user which has a return call that
does not return a status:

  my ($cookie) = $r->header_in('Cookie') =~ /${auth_type}_${auth_name}=([^;]+)/;
  $r->log_error("cookie ${auth_type}_${auth_name} is $cookie") if $debug >= 2;
  return unless $cookie;


changing the last line to

 return DECLINED unless $cookie;

seems to do the right thing, and gets rid of that pesky warning.

Finally, I can have an error log that logs only real errors ;-)
