reload modules for development environments on modperl2

[Jeremy Wall <je...@marzhillstudios.com>]

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?

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.

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.
