Might there be any documentation or example code for using CLISP's
interface to foreign objects? I'm contemplating talking to the Apache
API. (I also want to know for other reasons -- I'm also interested in
talking to libpcap...)
I'd really like to be able to find a way to write Apache servlets in
Common Lisp. There has to be a way to do this without a lot of pain
and suffering being involved:
o I don't want to port some behemoth like CL-HTTP to CLISP so I can
write web code (CL-HTTP doesn't seem to work with CMUCL 18c);
o Apache seems to be doing a good job of tying programs and whatnot
to the web, so I say, let it manage that job;
o Because CLISP is able to write such small images, it seems like
it's in a good position to compete, resource-wise, with less
optimal languages that have a reputation of producing small and
fast runtime code.
o I tried to get the onShore IMHO stuff running, using Apache JServ
and its connection to CMUCL, which rapidly got way out of control.
Just for giggles, a few minutes ago, I did a completely unscientific
experiment to test the relative level of load for Perl/CGI code as
compared to essentially the same thing using CLISP. In a trivial
"Hello, Web" Perl program, I was able to drive the load up to about
.35 on my Indy just by continuously banging on the program for about
I did the same thing with a "Hello, Web" program written in Common
Lisp, compiled, and dumped to a memory image, then wrapped with some
Bourne shell that would invoke clisp quietly, without loading startup
stuff, and using the image I dumped. Banging away on the server, I
was able to get the load up to about .25.
Of course, this isn't highly important, since I really don't want to
write CGI code, but having just cranked out some CGI Perl to get a
small job done quickly, I'm beginning to wonder if maybe the "cost of
entry" for writing web server-side code in Lisp is just too high...
