OT: Really wierd problem with TT2
Hi:
I know this is not modperl specific, but, I use TemplateToolkit2 to
create pages on my site. My site contains a lot of photos and I want to
add listings with thumbnail preview. But element attributes magically
appears when generating the page. The page contains no java script or
other stuff that can account for this:
In my handler I create a list reference with one entry preview per page
like this:
my $item;
$item->{path} = getPath($page->{page_id});
$item->{title} = $page->{title};
$item->{ctime} = dateStr($page->{ctime});
my $text = $page->{page};
if (my ($src) = $text =~ //io) { # Get image source
$src =~ s/\/?photo/photo\/thumb/gio;
$item->{img} = $src;
}
$text =~ s/.*?<\/object>//go; # Remove object-element
$text =~ s/.*?<\/h\d>//gio;
$text =~ s/\n?<\/p>/\n/go; # Replace paragraph by newline
$text =~ s/<.*?>//go; # Remove all elements
$text = substr($text,0,256); # Get first 256 chars
$text =~ s/\.[^\.]*?$/./go; # Chomp to last period
$text =~ s/\r?\n\r?\n\r?/\n/go; # Remove double new-lines
$item->{text} = $text;
So, the item contains the title, extract of the content and possibly
path to a thumbnail image.
In my template I have this:
[% FOREACH item IN list %]
[% IF item.img %]
[% END %]
[% item.title %]
Posted: [% item.ctime %]
[% item.text %]
[% END %]
Which produces this output:
Beach of Paris
Posted: 2007-01-07 00:42:25 UTC+01
This august in Paris they ...
So: where does the alt, title and class attributes in the image element
come from??? I tried first to set these in the template, and discovered
the dublicates when I tried to validate the result. Now, removing these
attributes from the template and restarting Apache several times, I
still get these extra "ghost" attributes.
If you like to see for yourself without my edits, the generated output
is here: http://www.locolomo.org/photos/ and the full template is here:

This is something you will have to figure out by experimenting. Print
the contents of $item->{img} to your error_log. Take the item.img part
out of your template. Change things until you understand where it's
coming from.

Yes taking a few hours off the bug is obvious, in the parsing for
the source path of the image:
if (my ($src) = $text =~ //io) {
Should be:
if (my ($src) = $text =~ //io) {
The first takes all the attributes of the original image ... DUH!
Well, thanks.

urgent help needed - this script does not chdir
Hi,
I am new to modperl and needs help, i have a script which works fine in
non-modperl enviornment but when i include in modperl::registry then mine
scripts when invoked via a browser finds itself in / directory i mean the
file or script do not include the files with the require command i mean the
relative path it cannot understand.
Additionally when i give this block,
BEGIN{
chdir('/home/absolute/directory');
};
then the script will run fine for some time and not fine i mean will give
error on including a function in a library included by require.
Pl. help me , i need a sol urgently ,
thanks ,

does begin block effect any performance in modperl
Hi friends,
i need to know that if i add the following block then will it affect
anything in the execution of modperl apart from first time run.
BEGIN{
require'abc.pl';
require'large_file.pl';
};
I mean anything relative to the performance.is the begin block called
everytime orjust the first time and is it safe to define a function in a
file and call it with this method rather than a package ,
Pl. help me.
Thanks,
Abhishek jain.

The begin blocks are only run at compile time, so won't affect the
performance of future requests.

Re: Lost ENV variable value .........
Can you let us know how you did this, Can we update the REMOTE_USER variable, From where can we find the documentation. Does mod_cas takes configurable parameters,is it s Authentication module, Our objective is simply, call the CAS, serivice_validate retrive the xml and look for a specific attribute, if it is there update the remote_user variable, that is it. We dont bother about any PGTIOU etc... We only care about service_validate.

How to extract a parameter
Hi,
Is there a easy way to extract the ticket(may be using a Regular Expression)
parameter from a URL as follows
http://localhost/myTest.pl?ticket=ST-2-zbwAtOlYlfzoC6knUXP9&name=test
I need to extract this from the perl_module where I have a handler for the
$r as follows, which is called from the httpd.conf
sub authen_handler {
my $self= shift;
my $r = shift;
..
Also would like to know how to get the entire queryString?

Re: Lost ENV variable value .........
I agree but look at the following scenario if User hits http://somedomain/test.pl?param1=x¶m2=y and if a failure happens in the authenticate handler I need to redirect to http://casmachine:8443/cas/login?service= that is http://casmachine:8443/cas/login?service=http://somedomain/test.pl?param1=x¶m2=y even though the http://casmachine:8443/cas/login?service=http://somedomain/test.pl is static users might requrest for inner files. Hence it is not static Due to this reason I thought I cant use AUTH_REQUIRED and use ErrorDocument Please let me know above can be achieved even using errorDocument Thanks Peter Rosenthal wrote: > > I have used CAS myself, but instead of attempting to implement the server > module for CAS authentication I used mod_cas.

Re: mod_perl installation
If you're running on Linux/ Sun, I think most people avoid threading for performance reasons. If you're going to be on Windows, you don't have a choice: threading is compulsory. You may want to read up on the various MPM models for each OS. Octavian Rasnita wrote: Hi, How it is recommended to install perl if I also want to use it with mod_perl? With or without threading support? With or without support for multiplicity? It gives an error when installing with Apache 2.24, and I am trying to see if I don't make some mistakes. Thank you.

There is an easy way, that emulates CGI's methods. It's called
libapreq2, and the class you're looking for is Apache2::Request. To get
the ticket for example, you create an instance of the class, and called
$req->param("ticket");
It's not part of the mod_perl package, but it is easily available.

Because each main-script load those scripts independently,then there are multi-copies of those scripts in each apache's process space,it distinctly waste the memory. It's good to define the scripts needed to be loaded as classes and access their methods by OO way. -- Books below translated by me to Chinese.

Functionality works/test failed
Hi,
I am in the process of changing a perl module written to a Perl
Authentication handler.
Well when I try to deploy the module it failed in the ' make test' stage
all the other steps went ok.
But the functionality works as expected.
When we execute make test it gives the following error
Failed Test Stat Wstat Total Fail Failed List of Failed
---
t/00.load.t1 256 11 100.00% 1
2 tests skipped.
Failed 1/3 test scripts, 66.67% okay. 1/1 subtests failed, 0.00% okay.
make: *** [test_dynamic] Error 255
I found out that the reason for failure is the following line
use Apache2::compat;
but when I remove this entry the make test gives no errors but functionality
fails and in the log it says that
Can't locate object method "user" via package "Apache2::Connection" at
/usr/lib/perl5/site_perl/5.8.8/AuthCAS.pm line 512.\n
which is basically $r->connection->user($user);
line in the source.
Also in the in the 't' folder the source of the 00.load.t is as follows
use Test::More tests => 1;
BEGIN {
use_ok( 'AuthCAS' );
}
diag( "Testing AuthCAS $AuthCAS::VERSION" );
Let us know how to get around with this,
