Perl Sections Issue

[David Wheeler]

Hi All,

I just realized that there's an issue with <Perl> sections. It seems 
that, because items like $Location are managed as hash references, and 
because you can't predict the order in which a hash is evaluated (esp. 
in Perl 5.8.1 and later), that some sections can be overridden. For 
example, I have code similar to this in Bricolage:

  $Location = { "/data" => { SetHandler => 'default-handler' },
                "/data/preview" => {
                    SetHandler       => 'perl-script',
                    PerlFixupHandler => 
'Bric::App::PreviewHandler::fixup_handler',
                    PerlHandler      => 'Bric::App::Handler'
               }};

However, I find that often, the resulting httpd.conf directives get 
written and sent to Apache as:

    <Location /data/preview>
        PerlFixupHandler Bric::App::PreviewHandler::fixup_handler
        SetHandler perl-script
        PerlHandler Bric::App::Handler
    </Location>
    <Location /data>
      SetHandler default-handler
    </Location>
As a result, the settings in /data/preview do not take effect, because 
/data is declared after /data/preview.

I tried using arrays to get around this issue:

  $Location = [ { "/data" => { SetHandler => 'default-handler' }},
                { "/data/preview" => {
                      SetHandler       => 'perl-script',
                      PerlFixupHandler => 
'Bric::App::PreviewHandler::fixup_handler',
                      PerlHandler      => 'Bric::App::Handler'
                 }}
              ];

But then Apache simply doesn't start. There are no error messages, I 
just get "httpd could not be started".

Is anyone aware of another workaround for this issue? And if not, what 
can we do to fix it?

Many TIA,

David
