Re: $TAINTED in latest CGI.pm v2.87

in reply to $TAINTED in latest CGI.pm v2.87

the warning is produced from the $ENV{REQUEST_METHOD} . ''. it seems $ENV{REQUEST_METHOD} is undefined, which causes the 'uninitialized value' message.

why the request method is not set, i'm not sure.

    You are right. I went back and put CGI.pm v2.87 back in and added
a line:
$ENV{REQUEST_METHOD} = $ENV{REQUEST_METHOD} || '';

$TAINTED = substr($ENV{REQUEST_METHOD}.'',0,0);

and it works fine now.  There must be a better idiom for that added line ?

      how about 

      $ENV{REQUEST_METHOD} ||= '';

      [download]

      but it will replace a false value, such as the number 0. in perl6, that's better written as:

      $ENV{REQUEST_METHOD} //= '';

      [download]

      which will only default undefined values

[d/l]
[select]
      defined or $_ = '' for $ENV{REQUEST_METHOD};

      Makeshifts last the longest.
