I also don't think these two bits of functionality need to be in the same module, although they do use parts of the same op code tree. I'd like to hear a bit more discussion about it before I go about patching StatINC.pm I know they're busy, but if the main mod_perl maintainers have anything to add, I'd be very interested. -- Matt/ Fastnet Software Ltd.

That seems right - so perhaps it would be better to integrate the StatINC functionality into Apache::Reload than the other way around. If it's called Apache::Reload, then it might make sense to have a directive like 'ReloadMode' that could be set to 'INC' to emulate StatINC's behavior, or to 'Files' to explicitly name the files you want checked with every request, or to 'Slave' (perhaps a bad choice) to only check those files that do the "use Apache::Reload" thingy you've written. 'Files' and 'INC' wouldn't be very different in implementation, but 'Files' gives you finer-grained control. They both just take a list of files and check them with every request. One nice thing about this approach is that you could set the ReloadMode differently for different URI files/directories in httpd.conf, so you wouldn't have to shotgun your entire site when you just need to test one little thing in your private area. It might be nice to have only one [main] module for reloading changed code files, both because of memespace issues and because the actual reloading task seems to be a tricky one, and it would be nice to only have to get it right once. But if it doesn't make sense to combine the approaches into one module, it doesn't make sense. -Ken Williams The Math Forum [EMAIL PROTECTED]

$$foo in Apache::ASP
I'm running Apache 1.12, Mod_Perl 1.23, Apache::ASP 2.03 on NT. I can't get the construct % $foo = "xxx"; $$foo="yyy"; % to populate $xxx with "yyy". Works in normal Perl. Any sugeestions ? Thanks Rod

Re: RFC: Apache::Reload
According to Matt Sergeant: package Apache::Reload; What I've always wanted along these lines is the ability to load something in the parent process that would take a list of directories where modules are always checked and reloaded (for your local frequently changed scripts) plus one filename that is checked every time and if it has been touched then do the full StatINC procedure. This would keep the number of stat's down to a reasonable number for production and still let you notify the server when you have updated the infrequently changed modules.

This would keep the number of stat's down to a reasonable number for production and still let you notify the server when you have updated the infrequently changed modules. Thats an interesting idea.
