[Templates] Two issues - Processing problem and caching problem (bug?)

Wed, 12 Jul 2006 10:12:09 -0500

I have two issues, one dealing with template processing, and the other
dealing with template caching.

the first issue, I'm using mod_perl and apache to process all .phtml
files as TT2 templates, using this PerlHandler:
    sub handler {
      # load apache request object
      my $request = shift;

      # display 404 if requested template file does not exist
      return NOT_FOUND unless(-e $request->filename());

      # unless a Template object already exists, create new
      $TT ||= Template->new({
        INCLUDE_PATH => $ENV{'DOCUMENT_ROOT'},
        ABSOLUTE     => 1,
        EVAL_PERL    => 1,
        LOAD_PERL    => 1
      });

      # print content-type and process template
      $request->content_type('text/html');
      $TT->process($request->filename(), { 'uri' => $request->uri },
$request ) || do
      {
        $request->log_reason( $TT->error() );
        return SERVER_ERROR;
      };

      # return status to mod_perl
      return OK;
    }

this modules compiles and runs just fine.  now, when I try to display
a page that contains the following text:
    Testing
    ...
    Testing 1 2 3
    ...

I somehow get this served from apache:
    <html><head></head><body>TiTi13</body></html>

i'll be honest, i have no idea whats happening here.  the mangling of
the page content is pretty obvious, but I'm not sure why its mangling
it.  plus, i have NO idea where those html tags are coming from...

as for my second problem, the caching issue...I'm using absolute paths
to retrieve my templates (from a mod_perl handler, so it could come
from outside of the server's DOCUMENT_ROOT, if there's a spurious use
of Aliases), and I'd like to cache the compiled templates for
performance.  however, if i enable caching *with* absolute paths:
    ABSOLUTE => 1,
    COMPILE_DIR => "/home/test/cache"

I get a 500 (internal server error).  for instance, if someone
requests the template file '/home/test/public_html/test.phtml', I get
this error in my apache log:
    mkdir /home/test/cache//home: Permission denied at
    /usr/lib/perl5/vendor_perl/5.8.8/i386-linux/Template/Provider.pm line 398
    "/var/log/apache2/error_log" [converted] 54L, 2804C

It seems like its automatically adding a trailing slash to
COMPILE_DIR, and then choking on the leading slash of the absolute
path of the template file...Is this a bug?  If so, any ideas for a
workaround?
