reload modules for development environments on modperl2

I currently use Apache2::Reload on my development environments. However it's
usefulness has been spotty particularly on win32 environments. Someone
recently recommended Module::Refresh to me as an alternative.

I was wondering in other peoples experience has been with modperl module
reloaders and refreshers. Or do most of you just prefer to go with an apache
restart?

I can't speak for windows, but Apache::Reload or Apache2::Reload work
really well for me.

PerlModule Apache2::Reload
PerlChildInitHandler Apache2::Reload
PerlInitHandler Apache2::Reload
PerlSetVar ReloadAll Off
PerlSetVar ReloadModules "X::* Y::*"

Of course it doesn't play nice with fatal warnings, so you'll want this
in your code:

use warnings FATAL => 'all', NONFATAL => 'redefine';

I tend to do final testing with Reload still on, but enabling
fatal warnings for redefines too.

FWIW, I have not had much luck with Apache2::Reload in my development
environment (Linux, Apache2 Prefork MPM). Most of the time when I
change something, it produces "Not a CODE reference" type errors.

I have had much better luck with Module::Refresh. I did it this way to
only reload packages starting with MyApp::

in httpd.conf

PerlInitHandler MyApp::Apache2::Reload

the module looks like this:

package MyApp::Apache2::Reload;

use Module::Refresh;

my $cache = Module::Refresh->new;

sub handler : method {
for my $mod (keys %INC) {
next unless $mod =~ /^MyApp/;
$cache->refresh_module_if_modified($mod);
}
}

1;

__END__

This has worked perfectly for me.
