Thanks Lance for your reply.
I have already put $|=1 at the beginning of the script. Actually the output
is not blocked.
And I have changed the script to:
sub template_parse
{
my $template_file = shift;
my $vars_hashref = shift;
print 'before creating Template->new';
my $tt = Template->new({INTERPOLATE => 1, INCLUDE_PATH =>
["$root/cgi-bin"]}) ||
do{ open F, ">$root/cgi-bin/errorlog.txt"; print F "$Template::ERROR\n";
close F;};
you aren't checking here to see if you sucessfully opened the file. Is
$root undef at this point, possibly? Do you have warnings on?
Also I would use "warn" for debugging output, then you don't have to
worry about whether $| is set or not, and if you give warn() input that
doesn't end in newline, it will give you a handy line and file name so
you can find the debug statements later.
print 'after creating Template->new';
my $parsed;
$tt->process($template_file, $vars_hashref, \$parsed) or die $$tt->error;
return \$parsed;
}
after call the template_parse subroutine, there is no errorlog.txt exist at
all and the output is still the same. It looks like the program exit inside
the Template->new and it get lost.
It could be the problem of server resource shortage?

Subject: Re: [Templates] very strange Template->new behave
Try running with $|++ at the top of your script. Maybe
it's making it past the new and your program is
blocking on writing to the $template_file. Since
stdout may be buffered you aren't seeing it.
Alternately write the debug output to a file.

Hi,
I have a strange problem on Template->new() method
on Template Toolkit in a cgi script.
The program just stops at Template->new() instead of
creating a new object. Could anybody give me some
clues on how to resolve it?
Thanks in advance.
Anya
The program looks like:
sub template_parse
{
my $template_file = shift;
my $vars_hashref = shift;
print 'before creating Template->new';
my $tt = Template->new({INTERPOLATE => 1,
INCLUDE_PATH => ["$root/cgi-bin"]}) || die
"$Template::ERROR\n";
print 'after creating Template->new';
my $parsed;
$tt->process($template_file, $vars_hashref,
\$parsed) or die $$tt->error;
return \$parsed;
}
The output is
before creating Template->new
it stops at my $tt.....; and no error message shows.
This subroutine is inside a cgi script with a https
request to another server with XML format. Template
toolkit is used to display the response.
The same subroute works at other cgi scripts without
https request.
