= COPS =

COPS stands for Calibre OPDS Php Server.

COPS output is valid the unofficial OPDS validator : 
http://opds-validator.appspot.com/

= Why ? =

In my opinion Calibre is a marvelous tool but is too big and has too much 
dependancies to be used for its content server.

That's the main reason why I coded this OPDS server. I needed a simple 
tool to be installed on a small server (Seagate Dockstar in my case).

I initially thought of Calibre2OPDS but as it generate static file no
search was possible.

So COPS's main advantages are :
 * No need for many dependancies.
 * No need for a lot of CPU or RAM.
 * Not much code.
 * Search is available.
 * With Dropbox it's very easy to have an up to date OPDS server.
 * It was fun to code.

= Prerequisites =

1. 	PHP 5.3 with GD image processing & SQLite3 support.
2. 	A web server with PHP support. I only tested with Nginx 1.1.14. For now
    there is support for X-Accel-Redirect which is Nginx specific.
3.  The path to a calibre library (metadata.db, format, & cover files).

On any Debian base Linux you can use :
 aptitude install php5-gd php5-sqlite

= Install =

1.  Extract the zip file to a folder in web space (visible to the web server).
2.  If a first-time install, copy config_default.php to config_local.php
3.  Edit config_local.php to match your config.

In my case I installed COPS in a subdomain. Here is my nginx config file :
server {

    listen [::]:80;

    server_name opds.mydomain.com;

    access_log  /var/log/nginx/opds.access.log;
    error_log /var/log/nginx/opds.error.log;
    root   /var/www/opds;
    index feed.php;

    location ~ \.php$ {
       include /etc/nginx/fastcgi_params;
       fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
       fastcgi_pass    unix:/tmp/fcgi.sock;
    }

    location /Calibre {
        root /home/calibre/Dropbox;
        internal;
    }
}

Beware in this case my Calibre database is in /home/calibre/Dropbox/Calibre/ so
the internal location of nginx has to split like that.

If your Calibre database is inside your web directory then there is no need for
an internal location.

If you choose to put your Calibre directory inside your web directory then you
will have to edit /etc/nginx/mime.types to add this line :
application/epub+zip epub;

= Known problems =

 * Only tested with Nginx.
 * Contain Nginx specific code.
 * Only works with EPUB (not MOBI or PDF).
 * certainly many many more.

= Disclaimer =

I only tested on Debian with Nginx so I have stricly no idea if it works
with Apache or any other web server.

On the OPDS client side I mainly tested with FBReader and Aldiko on Android.
