[cgiapp] code reuse.

[James.Q.L]

Greetings,

I would like to seek opinions on the issue of reusing code. i am slowly finding common things that
i need to do within my C::A apps.  i have put the common codes into C::A plugin or just normal
module but i don't really like the way it is organized. 

one example is that there is event logging in every apps so i created a C::A::P::EventLogging,
then in my app's Base module i have something like the following. btw, Company is the top
namespace for shared libraries used or will be used in multiple apps.
	
	package MyAPP::Base;
	use Company::CAP::EventLogging;
	use Company::Util;
	use MyAPP::DB;

	sub cgiapp_prerun {
		
		my $dbh = MyApp::DB->dbh;
		my $uuid = Company::Util->uuid( { dbh => $dbh, 
								uname => $ENV{REMOTE_USER},
		} );	
		$self->param('uuid', $uuid);
		$self->elog_config( { dbh  => $dbh, 
						uuid => $uuid,
		} );
	
		# then i can do 
		$self->elog("blabla");	
	}

two things that i don't like the above code are
	
1. passing $dbh to every shared lib that needs it. the $dbh is coming from each app's MyAPP::DB
module. 
2. $uuid (there are other properties too)  is used in other places (controller and model ) in the
app as well. in controller i just  call $self->param to get it but for controller i have to pass
it as an extra parameter.

i can't think of a good way to tackle my issues.. what's your opinion?
