What I do _want_ to end up is quite simple, though. I want to end up with is a long running process running under a user id different from the web server, listing on an ONC RPC port or a similar communication channel for requests, having a pool of threads and a pool of database connections governed by a ressource management mechanism similar to what Apache offers for number of worker threads (StartServers, MinSpareServers, MaxSpareServers, MaxClients like limits for threads and DB connections). I want that thing to keep compiled bytecode in memory, r/o and shared between the threads, if possible and I want to limit that amount of memory in a LRU style fashion, so that unused bytecode is being dropped in low memory situation, but compiles are saved when there is enough memory. I want that thing to be able to execute unmodified PHP scripts, if possible, dropping ressources at script end as before, but keeping bytecode around. I want that thing to keep session variables actively, no serialization needed, and to work with pooled ressources such as database connections in a sane manner. That way, references and ressources will not be a problem as session variables. And I believe that this will be slightly larger than your average sapi interface, but not so much that it would not fit into a sapi/ directory in your normal PHP distribution, including the stub program as a CGI and a module version. I would not call this breaking the language, in fact the average user not using session_*() functions probably will not even notice the difference besides faster execution times. Now please tell me where the hole is in my reasoning. Kristian -- Kristian Köhntopp, NetUSE AG Siemenswall, D-24107 Kiel Tel: +49 431 386 436 00, Fax: +49 431 386 435 99 Using PHP3?
