[Bese-devel] ucw setup - a newbie question

[Alec Segal]

Just  have ucw set up and trying to get any response from it. No luck with
any backend.
I use the latest sources from darcs ucw_dev.

SBCL 0.9.8

ucw.log (lisp was restarted every time):

(+INFO+ 3352746404 IT.BESE.UCW::UCW-LOGGER "Starting up standard server
#<STANDARD-SERVER MULTITHREAD-HTTPD-BACKEND 2 {B2F6149}>.")
(+INFO+ 3352751202 IT.BESE.UCW::UCW-LOGGER "Starting up standard server
#<STANDARD-SERVER ARANEIDA-BACKEND 2 {B342C09}>.")
(+INFO+ 3352752177 IT.BESE.UCW::UCW-LOGGER "Starting up standard server
#<STANDARD-SERVER MULTITHREAD-MOD-LISP-BACKEND 2 {B3D1249}>.")

As soon as I try to connect with through http, I get an error in the
ucw-backend.log:

(+ERROR+ 3352743688 IT.BESE.UCW::UCW.BACKEND "Error in worker loop:
#<UNDEFINED-FUNCTION READ-REQUEST {BDD2D29}>.")
(+ERROR+ 3352743688 IT.BESE.UCW::UCW.BACKEND "Worker thread #<
IT.BESE.UCW::HTTPD-WORKER {BD3D6B9}> reported #<UNDEFINED-FUNCTION
READ-REQUEST {BDD2D29}>.")

(+INFO+ 3352751202 IT.BESE.UCW::UCW.BACKEND "Starting up ARANEIDA backend
#<ARANEIDA-BACKEND {C1C37C1}> on http://127.0.0.1:8080/")
(+ERROR+ 3352754733 IT.BESE.UCW::UCW.BACKEND "Error in worker loop:
#<UNDEFINED-FUNCTION READ-REQUEST {A746601}>.")
(+ERROR+ 3352755066 IT.BESE.UCW::UCW.BACKEND "Error in worker loop:
#<UNDEFINED-FUNCTION READ-REQUEST {C67BF11}>.")

For some reason httpd-worker-loop/handle in multithread-httpd.lisp does not
have read-request and make-response functions defined (though they are in
the httpd.lisp). I am less clear what is going on with other backends.
IMHO ucwctl needs to be fixed (the value for :backend must be a list):
...
                  $EVAL "(ucw:create-server :backend '(:$BACKEND
                                             :host \"$HOST\"
                                             :port $PORT)
...
Starting ucw trough the ucwtl I am getting exactly the same error.

What is the url to access admin and demo scripts?
I was trying http://127.0.0.1/index.ucw and http://127.0.0.1/admin/index.ucw,
amd just plain http://127.0.0.1
but everything resulted in the errors I was trying to describe earlier.

I set
UCW-USER> (setf *debug-on-error* t)
Here is the sldb trace with the httpd backend:
