I get "die" erors in one log file (the one specified for my virtual
host) and warn errors in /var/log/apache2/error.log
What on Earth could be the reason for that?

$r->path_info unreliable?
In my handler I call $r->path_info to determine the path used to call my
script.
I am trying to have a test version of my code using the same module but
which reads different data based on the path.
So I have:
SetHandler perl-script
PerlResponseHandler Apache::MyPackage::FrontEnd2
SetHandler perl-script
PerlResponseHandler Apache::MyPackage::FrontEnd2
In FrontEnd2
sub handler {
my $r =3D shift;
warn $r->path_info;
if($r->path_info =3D~ /test/i){
## Load test data
}else{
## Load real data
}
This works for another package I have exactly like this, but in this
case $r->path_info is empty.
I am stumped.

Trouble with script execution
I am having a nproblem executing my handler.
The short of it is it is when I make a change to the script I have to
restart the server to get it noticed, and it does not always call the
same code.
The lng of it:
I have a package with a 'handler' function.
It starts...
package Apache::Script;
use strict;
use Apache2::Const qw(:common);
use Apache2::Connection;
[snip]
sub handler {
warn "Apache::Script::handler $$ '".join(", ", @_)."'";
my $r = shift;
[snip]
Many more lines like...
warn "Apache::Script::handler";
And in the config file:
SetHandler perl-script
PerlResponseHandler Apache::Script
Repeatedly loading the URL I get different results almost every time.
With the first 'warn' statement producing oyutput almst every iteration
and occasionally the later warn statements not being executed, and often
with no output.
Making changes t the script (adding debugging 'warn' statements) are
only reliably (ish) noticed if I restart the server. There is some
unreliability in my code (bugs) I am trying to track down but it is
confounded by the fact I am not sure what mod_perl is doing.
There seems to be a time element. After restarting the server
everything goes well for a while (minutes) but soon behaviour changes
and I am back to only some of the code executing (with no oither changes
but the passing of time).
I thought mod_perl would reload code that changed. Is this wrong?

The ErrorLog issue only happens under mod_perl. Given that all logs
were in the appropriate directory but I went and checked and it is set
appropriately in apache2/envvars. If you look at the snippet of my
configuration file you will see I set the error log just before setting
up mod_perl.

Thank you that is useful. I will look into that. I have gotten that
file. Is there some documentation to go with it?

Trouble with mod_perl API: E.g., Apache2::Directive::conftree()
I am having a lot of trouble with mod_perl APIs.
The short of it is that when I say:
use Apache2::Directive ();
my $tree = Apache2::Directive::conftree();
my $documentroot = $tree->lookup('DocumentRoot');
warn "\$documentroot '$documentroot'";
I get:
[Wed May 14 12:13:43 2014] -e: Use of uninitialized value $documentroot
in concatenation (.) or string at /home/worik/Worik.org/cgi/track line 11.
[Wed May 14 12:13:43 2014] -e: $documentroot '' at
/home/worik/Worik.org/cgi/track line 11.
in the logs.
I copied the code from
https://perl.apache.org/docs/2.0/api/Apache2/Directive.html
The longer of it is:
In the past (15 years ago) I installed mod_perl and forgot about it. I
set up my perl cgi script handler to be mod_perl in httpd.conf, and the
only real effect it had on my development cycle was I often had to
restart Apache to get it to notice I had changed a script.
These days I am more ambitious and am returning to Web programming after
a long break.
I expect mod_perl to still be useful to cut the overhead of starting
Perl. I expect a high throughput this time around, each request will be
worth very little to me so I want lots and lots of requests. SO far so
good.
I have set up my server:
## mod_perl2 configuration
Alias /cgi/ /home/worik/Worik.org/cgi/
PerlModule ModPerl::Registry
## PerlModule Apache::Registry
PerlSwitches -T
ErrorLog ${APACHE_LOG_DIR}/Worik.error.log
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders
Options +ExecCGI
Order allow,deny
Allow from all
Now I would like to use the API. In the first instance I want to find
what the directory is I am running in. So I want to say:
use Apache2::Directive ();
my $tree = Apache2::Directive::conftree();
my $pwd = $tree->lookup("cgi");
But that fails just like the example at the start of this email.
Also my errors are coming out in the wrong log. When I say warn("foo")
I expect it to come out in the file specified by the ErrorLog directive
but it comes as:
[Wed May 14 12:22:53 2014] -e: foo at /home/worik/Worik.org/cgi/track
line 12.
in /var/log/apache2/error.log which is not what I specified.
I am at a loss. Is the documentation up to date? Is mod_perl still
being used out there?
