isso and fastcgi

[22decembre]

I am trying to setup isso (python comment system) on OpenBSD/httpd. It is installed fine (all dependencies installed in a virtualenv inside the httpd chroot). My problem comes with the link between httpd and isso.

Here is what I get if isso get an unix socket in /var/www/tmp/isso.sock with this httpd conf':

location "/isso/*" {
                #root /isso strip 1
                log style combined
                log error isso-error.log
                log access isso-access.log
                fastcgi socket "/tmp/isso.sock"
                }

I load a webpage with something in isso : https://.../isso/js/embed.min.js

stephane@blackblock:/var/www/isso doas -u www env LANG=C.UTF-8 bin/isso -c isso.cfg run

    return self.client_address[0]

----------------------------------------

Starting httpd on debug mode shows nothing now. Other sockets (php) are not affected and running fine.

----------------------

Now I launch isso with a network socket, I don't see anything while loading pages :

 location "/isso/*" {
                #root /isso strip 1
                log style combined
                log error isso-error.log
                log access isso-access.log
                fastcgi socket ":1234"
                #fastcgi socket "/tmp/isso.sock"
                }

But if I wget the same javascript from the localhost directly from isso, I indeed get the file :

stephane@blackblock:/tmp wget http://localhost:1234/js/embed.min.js
--2017-01-01 20:35:27--  http://localhost:1234/js/embed.min.js

Sorry for it being quite messy (to my own taste !).

I cannot figure it out : isso seems to run fine when running as a small webapp, but then httpd does not seem to forward requests. But when isso is running as a file socket, we can see httpd forward something to isso, just it does not work fine.

Someone has a suggestion ?
