Stefan Laudemann 94f7256564 Adds missing comma to pass (x['neighbor'], ) as tuple (not as str). 
As Python interprets "(elem)" as string and not as tuple,
maybe_node_by_mac() iterates over the single characters in the MAC-
addressed passed as parameter when called parse_vis_data(). Most of the
calls already use the "(elem, )" syntax to indicate that a tuple is
passed. However, there is still one call for which this is not the case
causing a noticable longer runtime due to calls to maybe_node_by_mac()
that cannot yield any useful result.

Data for Freifunk Map, Graph and Node List

ffmap-backend gathers information on the batman network by invoking batctl and batadv-vis as root (via sudo) and has this information placed into a target directory as the file "nodes.json" and also updates the directory "nodes" with graphical representations of uptimes and the number of clients connecting.

The target directory is suggested to host all information for interpreting those node descriptions, e.g. as provided by https://github.com/ffnord/ffmap-d3.git . When executed without root privileges, we suggest to grant sudo permissions within wrappers of those binaries, so no further changes are required in other scripts:

$ cat < $HOME/batctl
#!/bin/sh
exec sudo /usr/sbin/batctl $*
EOCAT

and analogously for batadv-vis. The entry for /etc/sudoers could be whateveruser ALL=(ALL:ALL) NOPASSWD: /usr/sbin/batctl,/usr/sbin/batadv-vis,/usr/sbin/alfred-json

The destination directory can be made directly available through apache:

$ cat /etc/apache2/site-enabled/000-default
...
        
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        
...

$ cat /etc/apache2/conf.d/freifunk
Alias /map /home/ffmap/www/
Alias /firmware /home/freifunk/autoupdates/

To execute, run ./mkmap.sh ../www The script expects above described sudo-wrappers in the $HOME directory of the user executing the script. If those are not available, an error will occurr if not executed as root. Also, the tool realpath optionally allows to execute the script from anywhere in the directory tree.

For the script's regular execution add the following to the crontab:

*/5 * * * * /home/ffmap/ffmap-backend/mkmap.sh /home/ffmap/www
