I definitely store "Site::Configuration" along with all the other
modules.
As you've identified, I use a mechanism similar to my "if $ENV{DEVMODE}"
example to automatically change the run-time configuration. The system
I use is based on a few ideas:
1. There are things called "environments", of which "production",
"staging", and "Mark's development" would be a few.
2. Each environment should have its own Apache server.
3. Environments need to be centrally managed.
4. The process for moving work between environments must be totally
consistent for Quality Assurance's sake.
5. Each environment is defined by a number of distinct run-time
settings.
Regarding number five, here is a list of run-time properties for
environments in my typical system:
ENVIRONMENT_NAME
DEV_ROOT
LOG_DIR
SITE_HOST_NAME
APACHE_IP
APACHE_ROOT
APACHE_PIDFILE
For each environment I have a hash containing values for these
parameters. A control script (run via sudo) is used to start and stop
Apache. This control script reads the environment name (e.g.,
"production", "mark", "jesse", etc.) from a UNIX environment variable,
and selects the proper hash of environment configuration settings. This
control script then *dynamically* creates an Apache "httpd.conf" from a
template (using HTML::Template, of course) populating things like the IP
address and host name. (N.b., the "DEV_ROOT" property is used to
automatically set PERL5LIB and HTML_TEMPLATE_ROOT.)
As you can imagine, this system eliminates the problems usually related
to moving changes between environments. I've been using this system for
years.
TTYL,
