I'll bring this up on the mod_perl dev list. I don't think we should advise people to use such a crazy construct.

The problems people encounter with ModPerl::Registry are usually not caused by inner subroutines, but rather by closures. The closures were always there, but were never noticed before in a non-persistent environment. Consider this:

my $q = CGI->new; show_name(); sub show_name { print $q->param('name'); }

This code will break when run in mod_perl because it forms a closure around $q, making it a private variable for the show_name() sub after compilation.

This problem can be fixed by making $q an our variable, but that's a poor programming practice, giving $q a large scope and persistence that it should not have. The correct fix is to pass the variables that the sub requires:

my $q = CGI->new; show_name($q); sub show_name { my $q = shift; print $q->param('name'); }

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
