By grabbing the latest Everything from CVS, you're kind of high-lighting the problem here: there is no current CVS of PerlMonks, because the code is kept in the database. There is no convenient way to get the latest code, let alone branch it for a major revision. It also makes the task of incorporating updates from Everything that much harder. This is why I think storing code in the database is not a good idea at this point. I'm sure there were reasons for it at the time, but it is counter-productive now.

When I referred to XML, what I was really thinking of was the way nodes are stored and the resulting update problems (some of them are described here). I don't think this would be such a problem with a more normalized database schema and a codebase that allowed for finer-grained locking during updates.

About the cache: subrefs are okay as long as Storable can handle them. Objects that can't be serialized can't be cached between processes at this point. At the moment, Perl threads are not very good at sharing objects so mod_perl 2 may not solve this issue any time soon. I'm not sure what your managed-forking idea is, but I don't see why it wouldn't have to deal with exactly the same issues mod_perl does.

I don't want to sound like I'm just whining about the code. I am grateful for the existence of this site and your part in creating the code that made it happen. I do think that some of the design ideas have not scaled well though, and that it will be hard to fix it completely without fundamental changes.
