$r vs. Apache2::RequestUtil->request
Hi, I'm confused about something. I am cleaning up some legacy Perl code in
our application, and I find a number of our custom Perl modules have
functions which require $r be passed to them solely for use in logging (e.g.
$r->log->error()). I want to remove that requirement, so I am changing
things around so that the code uses Apache2::RequestUtil::request to get the
request object when needed. This is working fine, except when I use the
object retrieved that way, the $r->log methods fail to write to the server
log. In addition, I see that the original $r and the new one from
A::RU::request are different:
use Data::Dumper;
print STDERR Dumper($r);
print STDERR Dumper(Apache2::RequestUtil->request);
yields
$VAR1 = bless( do{\(my $o = 158143776)}, 'Apache2::Request' );
$VAR1 = bless( do{\(my $o = 158116376)}, 'Apache2::RequestRec' );
Can someone help me understand this difference, and how to use the object
retrieved from A::RU::request to access the Apache2::Log methods? Why isn't
the original $r an Apache2::RequestRec object?
This is Perl 5.14.2, mod_perl 2.0.5
Thanks.

Apache2::Request is a Perl module which is part of the libapreq Apache
software project. You have to install apreq (
http://httpd.apache.org/apreq/ ) and then load the shared object in
httpd.conf via LoadModule. It contains many convenience methods that
CGI.pm normally provides.
Apache2::RequestUtil is part of the mod_perl2 core.
If you are using $r->log then you need to 'use Apache2::Log;' in
either startup.pl or your module.
Hope that helps.

Okay, never mind. The Apache2::Log methods are in fact working for me.
Stupid error.
I am still curious about the difference between the Apache2::Request object
which is the default request record accessor, and the Apache2::RequestRec
object which comes out of Apache2::RequestUtil::request.
