Does "not up to date" mean the code isn't working with current releases
of php 4 or 5? I'd be interested in giving it a try.
Forgive my ignorance of Apache and PHP internals, but I'm not
understanding the concept of your implementation. I'm not enivisioning
allowing a PHP script to be able to meddle with the Apache request
process.
I'm picturing an extension that would simply not allow an uncautious or
unknowing scripter to ruin the server, but would only allow him to store
all his app defs and data model startup stuff in a one-shot performance
booster. It could even do it in a separate (CLI?) interpreter and copy
the data over (but only once!) to the Apache-embedded interpreter using
a shared memory resource... hmmm.
I'm not versed enough to suggest a feasible implementation, but if
the overall goal is feasible then I'm willing to climb the learning
curve.
I'm also quite surprised there wasn't much interest in these concepts, I
admit the benefits would be small for most apps, but complex apps with
large data setup could save valuable time, and having persistent
namespaces/modules is plugged as a worthy feature of mod_perl and
mod_python, for what it's worth.
